158-546: The Cenepa River is a 185-km stretch of river where its basin borders Ecuador and Peru. The land around the Cenepa River Basin "presents a capricious topography that includes relatively broad inland valleys". For example, the Numpatkeim Valley, like similar valleys in the region that have narrow canyons and opportune farmland is not commonly found along many reaches of the river. Along the eastern banks of

316-933: A segregated basis. A flight training center was set up at the Tuskegee Institute in Alabama . Despite the handicap—caused by the segregation policy—of not having an experienced training cadre as with other AAF units, the Tuskegee Airmen distinguished themselves in combat with the 332nd Fighter Group . The Tuskegee training program produced 673 black fighter pilots, 253 B-26 Marauder pilots, and 132 navigators. The vast majority of African-American airmen, however, did not fare as well. Mainly draftees , most did not fly or maintain aircraft. Their largely menial duties, indifferent or hostile leadership, and poor morale led to serious dissatisfaction and several violent incidents. Women served more successfully as part of

474-585: A "disturbing failure to follow through on orders". To streamline the AAF in preparation for war, with a goal of centralized planning and decentralized execution of operations, in October 1941 Arnold submitted to the WDGS essentially the same reorganization plan it had rejected a year before, this time crafted by Chief of Air Staff Brig. Gen. Carl A. Spaatz . When this plan was not given any consideration, Arnold reworded

632-476: A Chief of Air Staff and three deputies. This wartime structure remained essentially unchanged for the remainder of hostilities. In October 1944 Arnold, to begin a process of reorganization for reducing the structure, proposed to eliminate the AC/AS, Training and move his office into OC&R, changing it to Operations, Training and Requirements (OT&R) but the mergers were never effected. On 23 August 1945, after

790-538: A Zone of Interior "training and supply agency", but from the start AAF officers viewed this as a "paper" restriction negated by Arnold's place on both the Joint and Combined Chiefs, which gave him strategic planning authority for the AAF, a viewpoint that was formally sanctioned by the War Department in mid-1943 and endorsed by the president. The Circular No. 59 reorganization directed the AAF to operate under

948-566: A blueprint. After war began, Congress enacted the First War Powers Act on 18 December 1941 endowing President Franklin D. Roosevelt with virtual carte blanche to reorganize the executive branch as he found necessary. Under it, on 28 February 1942, Roosevelt issued Executive Order 9082 , based on Marshall's recommendation and the work of McNarney's committee. The EO changed Arnold's title to Commanding General, Army Air Forces effective 9 March 1942, making him co-equal with

1106-555: A cassava plant is the root. This is long and tapered, with an easily detached rough brown rind. The white or yellowish flesh is firm and even in texture. Commercial cultivars can be 5 to 10 centimetres (2 to 4 in) wide at the top, and some 15 to 30 cm (6 to 12 in) long, with a woody vascular bundle running down the middle. The tuberous roots are largely starch , with small amounts of calcium (16 milligrams per 100 grams), phosphorus (27 mg/100 g), and vitamin C (20.6 mg/100 g). Cassava roots contains little protein , whereas

1264-470: A change of mood at the War Department, and of dubious legality. By November 1941, on the eve of U.S. entry into the war, the division of authority within the Army as a whole, caused by the activation of Army GHQ a year before, had led to a "battle of memos" between it and the WDGS over administering the AAF, prompting Marshall to state that he had "the poorest command post in the Army" when defense commands showed

1422-457: A complex division of administrative control performed by a policy staff, an operating staff, and the support commands (formerly "field activities" of the OCAC). The former field activities operated under a "bureau" structure, with both policy and operating functions vested in staff-type officers who often exercised command and policy authority without responsibility for results, a system held over from

1580-609: A controversial move, the AAF Technical Training Command began leasing resort hotels and apartment buildings for large-scale training sites (accommodation for 90,000 existed in Miami Beach alone). The leases were negotiated for the AAF by the Corps of Engineers, often to the economic detriment of hotel owners in rental rates, wear and tear clauses, and short-notice to terminate leases. In December 1943,

1738-429: A deleterious effect on operational training and threatened to overwhelm the capacity of the old Air Corps groups to provide experienced cadres or to absorb graduates of the expanded training program to replace those transferred. Since 1939 the overall level of experience among the combat groups had fallen to such an extent that when the demand for replacements in combat was factored in, the entire operational training system

1896-425: A famine reserve and is invaluable in managing labor schedules. It offers flexibility to resource-poor farmers because it serves as either a subsistence or a cash crop. Worldwide, 800 million people depend on cassava as their primary food staple. Cassava roots, peels and leaves are dangerous to eat raw because they contain linamarin and lotaustralin , which are toxic cyanogenic glycosides . These are decomposed by

2054-408: A fine powder and used to make tapioca, a popular starch used to make bubbles, a chewy topping in bubble tea . Alcoholic beverages made from cassava include cauim (Brazil), kasiri (Venezuela, Guyana, Suriname), parakari or kari (Venezuela, Guyana, Surinam), and nihamanchi (South America), A safe processing method known as the "wetting method" is to mix the cassava flour with water into

2212-560: A fungicide, then wrapping in plastic, freezing, or applying a wax coating. While alternative methods for controlling post-harvest deterioration have been proposed, such as preventing reactive oxygen species effects by using plastic bags during storage and transport, coating the roots with wax, or freezing roots, such strategies have proved to be economically or technically impractical, leading to breeding of cassava varieties with improved durability after harvest, achieved by different mechanisms. One approach used gamma rays to try to silence

2370-522: A gene involved in triggering deterioration; another strategy selected for plentiful carotenoids , antioxidants which may help to reduce oxidization after harvest. Cassava is subject to pests from multiple taxonomic groups, including nematodes, and insects, as well as diseases caused by viruses, bacteria, and fungi. All cause reductions in yield, and some cause serious losses of crops. Several viruses cause enough damage to cassava crops to be of economic importance. The African cassava mosaic virus causes

2528-720: A general autonomy within the War Department (similar to that of the Marine Corps within the Department of the Navy ) until the end of the war, while its commanders would cease lobbying for independence. Marshall, a strong proponent of airpower, understood that the Air Force would likely achieve its independence following the war. Soon after the Japanese attack on Pearl Harbor on 7 December 1941, in recognition of importance of

2686-788: A high-yielding form of shifting agriculture by the time of European contact in 1492. Cassava was a staple food of pre-Columbian peoples in the Americas and is often portrayed in indigenous art . The Moche people often depicted cassava in their ceramics. Spaniards in their early occupation of Caribbean islands did not want to eat cassava or maize, which they considered insubstantial, dangerous, and not nutritious. They much preferred foods from Spain, specifically wheat bread, olive oil, red wine, and meat, and considered maize and cassava damaging to Europeans. The cultivation and consumption of cassava were nonetheless continued in both Portuguese and Spanish America. Mass production of cassava bread became

2844-498: A higher effective yield. The use of tolerant and resistant cultivars is the most practical management method in most locales. Insects such as stem borers and other beetles, moths including Chilomima clarkei , scale insects, fruit flies, shootflies, burrower bugs , grasshoppers, leafhoppers, gall midges, leafcutter ants, and termites contribute to losses of cassava in the field, while others contribute to serious losses, between 19% and 30%, of dried cassava in storage. In Africa ,

3002-927: A legend that cassava was introduced in 1880–1885 CE to the South Indian state of Kerala by the King of Travancore , Vishakham Thirunal Maharaja, after a great famine hit the kingdom, as a substitute for rice. However, there are documented cases of cassava cultivation in parts of the state before the time of Vishakham Thirunal Maharaja. Cassava is called kappa or maricheeni in Malayalam , and tapioca in Indian English usage. Optimal conditions for cassava cultivation are mean annual temperatures between 20 and 29 °C (68 and 84 °F), annual precipitation between 1,000 and 2,500 mm (39 and 98 in), and an annual growth period of no less than 240 days. Cassava

3160-698: A major reorganization and consolidation on 29 March 1943. The four main directorates and seventeen subordinate directorates (the "operating staff") were abolished as an unnecessary level of authority, and execution of policies was removed from the staffs to be assigned solely to field organizations along functional lines. The policy functions of the directorates were reorganized and consolidated into offices regrouped along conventional military lines under six assistant chiefs of air staff (AC/AS): Personnel; Intelligence; Operations, Commitments, and Requirements (OC&R); Materiel, Maintenance, and Distribution (MM&D); Plans; and Training. Command of Headquarters AAF resided in

3318-570: A multiplicity of branches and organizations, reduced the WDGS greatly in size, and proportionally increased the representation of the air forces members on it to 50%. In addition to dissolving both Army General Headquarters and the chiefs of the combat arms , and assigning their training functions to the Army Ground Forces, War Department Circular 59 reorganized the Army Air Forces, disbanding both Air Force Combat Command and

3476-399: A myth relates that food derives from the body of Dewi Teknowati, who killed herself rather than accept the advances of the god Batara Guru . She was buried, and her lower leg grew into a cassava plant. In Trinidad, folk stories tell of a saapina or snake-woman; the word is related to sabada , meaning to pound, for what is traditionally a woman's work of pounding cassava. The identity of

3634-580: A perception of resistance and even obstruction then by the bureaucracy in the War Department General Staff (WDGS), much of which was attributable to lack of funds, the Air Corps later made great strides in the 1930s, both organizationally and in doctrine. A strategy stressing precision bombing of industrial targets by heavily armed, long-range bombers emerged, formulated by the men who would become its leaders. A major step toward

3792-478: A previous issue was the cassava mealybug ( Phenacoccus manihoti ) and cassava green mite ( Mononychellus tanajoa ). These pests can cause up to 80 percent crop loss, which is extremely detrimental to the production of subsistence farmers. These pests were rampant in the 1970s and 1980s but were brought under control following the establishment of the Biological Control Centre for Africa of

3950-471: A proposal for creation of an air staff, unification of the air arm under one commander, and equality with the ground and supply forces. Arnold's proposal was immediately opposed by the General Staff in all respects, rehashing its traditional doctrinal argument that, in the event of war, the Air Corps would have no mission independent of support of the ground forces. Marshall implemented a compromise that

4108-622: A rate of 80 kilometres (50 miles) per year, and as of 2005 was found throughout Uganda, Rwanda, Burundi, the Democratic Republic of the Congo and the Republic of the Congo. Viruses are a severe production limitation in the tropics. They are the primary reason for the complete lack of yield increases in the 25 years up to 2021 . Cassava brown streak virus disease is a major threat to cultivation worldwide. Cassava mosaic virus (CMV)

4266-589: A separate air force came in March 1935, when the command of all combat air units within the Continental United States (CONUS) was centralized under a single organization called the "General Headquarters Air Force" . Since 1920, control of aviation units had resided with commanders of the corps areas (a peacetime ground forces administrative echelon), following the model established by commanding General John J. Pershing during World War I. In 1924,

4424-473: A standard of combat proficiency had barely surpassed the total originally authorized by the first expansion program in 1940. The extant training establishment, in essence a "self-training" system, was inadequate in assets, organization, and pedagogy to train units wholesale. Individual training of freshly minted pilots occupied an inordinate amount of the available time to the detriment of unit proficiency. The ever-increasing numbers of new groups being formed had

4582-458: A temporary, nonstandard, headquarters in August 1944. This provisional fighter wing was set up to separate control of its P-38 groups from its P-51 groups. This headquarters was referred to as "XV Fighter Command (Provisional)". Eight air divisions served as an additional layer of command and control for the vast organization, capable of acting independently if the need arose. Inclusive within

4740-738: A thick paste, spread it in a thin layer over a basket and then let it stand for five hours at 30 °C in the shade. In that time, about 83% of the cyanogenic glycosides are broken down by linamarase ; the resulting hydrogen cyanide escapes to the atmosphere, making the flour safe for consumption the same evening. The traditional method used in West Africa is to peel the roots and put them into water for three days to ferment. The roots are then dried or cooked. In Nigeria and several other west African countries, including Ghana, Cameroon, Benin, Togo, Ivory Coast, and Burkina Faso, they are usually grated and lightly fried in palm oil to preserve them. The result

4898-511: Is a foodstuff called garri . Fermentation is also used in other places such as Indonesia, such as Tapai . The fermentation process also reduces the level of antinutrients, making the cassava a more nutritious food. The reliance on cassava as a food source and the resulting exposure to the goitrogenic effects of thiocyanate has been responsible for the endemic goiters seen in the Akoko area of southwestern Nigeria. A traditional method used by

5056-512: Is available on the US market in bottled form. Raw cassava is 60% water, 38% carbohydrates, 1% protein, and has negligible fat (table). In a 100-gram ( 3 + 1 ⁄ 2 -ounce) reference serving, raw cassava provides 670 kilojoules (160 kilocalories) of food energy and 23% of the Daily Value (DV) of vitamin C, but otherwise has no micronutrients in significant content (i.e., above 10% of

5214-484: Is grown in sweet and bitter varieties; both contain toxins, but the bitter varieties have them in much larger amounts. Cassava has to be prepared carefully for consumption, as improperly prepared material can contain sufficient cyanide to cause poisoning . The more toxic varieties of cassava have been used in some places as famine food during times of food insecurity . Farmers may however choose bitter cultivars to minimise crop losses. The generic name Manihot and

5372-434: Is harvested at three to four month, when it reaches about 30 to 45 cm (12 to 18 in) above ground; it is dried in the sun until its dry matter content approaches 85 percent. The hay contains 20–27 percent protein and 1.5–4 percent tannin . It is valued as a source of roughage for ruminants such as cattle. Cassava is used in laundry products, especially as starch to stiffen shirts and other garments. In Java,

5530-406: Is predominantly consumed in boiled form, but substantial quantities are processed to extract cassava starch, called tapioca , which is used for food, animal feed, and industrial purposes. The Brazilian farofa , and the related garri of West Africa, is an edible coarse flour obtained by grating cassava roots, pressing moisture off the obtained grated pulp, and finally drying it (and roasting in

5688-414: Is propagated by cutting the stem into sections of approximately 15 cm (5.9 in), these being planted prior to the wet season. Cassava growth is favorable under temperatures ranging from 25 to 29 °C (77 to 84 °F), but it can tolerate temperatures as low as 12 °C (54 °F) and as high as 40 °C (104 °F). These conditions are found, among other places, in the northern part of

5846-560: Is sometimes described as the "bread of the tropics" but should not be confused with the tropical and equatorial bread tree (Encephalartos) , the breadfruit (Artocarpus altilis) or the African breadfruit (Treculia africana) . This description definitely holds in Africa and parts of South America; in Asian countries such as Vietnam fresh cassava barely features in human diets. There is

6004-476: Is sufficient to eliminate all toxicity. The cyanide is carried away in the processing water and the amounts produced in domestic consumption are too small to have environmental impact. The larger-rooted, bitter varieties used for production of flour or starch must be processed to remove the cyanogenic glucosides. The large roots are peeled and then ground into flour, which is then soaked in water, squeezed dry several times, and toasted. The starch grains that flow with

Excess cyanide residue from improper preparation causes goiters and acute cyanide poisoning, and is linked to ataxia (a neurological disorder affecting the ability to walk, also known as konzo ). It has also been linked to tropical fibrocalcific pancreatitis in humans, leading to chronic pancreatitis. Symptoms of acute cyanide intoxication appear four or more hours after ingesting raw or poorly processed cassava: vertigo, vomiting, goiter , ataxia , partial paralysis, collapse, and death. It can be treated easily with an injection of thiosulfate (which makes sulfur available for

6320-483: Is vital when productivity has declined due to pests and diseases , and smallholders tend to retain less productive but more diverse gene pools . MeFT1 (FT) is a gene producing FT proteins which affect the formation of storage roots in many plants, including this one. Alleles in cassava include MeFT1 and MeFT2 . MeFT1 expression in leaves seems to not be photoperiodic , while MeFT2 clearly is. MeFT1 expression encourages motivation of sucrose towards

Bredeson et al. 2016 find the M. esculenta cultivars most widely used on that continent have M. carthaginensis subsp. glaziovii genes of which some appear to be CMD resistance genes . Although the ongoing CMD pandemic affects both East and Central Africa, Legg et al. found that these two areas have two distinct subpopulations of

6636-471: The Air Transport Command made deliveries of almost 270,000 aircraft worldwide while losing only 1,013 in the process. The operation of the stateside depots was done largely by more than 300,000 civilian maintenance employees, many of them women, freeing a like number of Air Forces mechanics for overseas duty. In all facets of the service, more than 420,000 civilian personnel were employed by

6794-526: The Army Service Forces , but the AAF increasingly exerted influence on the curricula of these courses in anticipation of future independence. African-Americans comprised approximately six per cent of this force (145,242 personnel in June 1944). In 1940, pressured by Eleanor Roosevelt and some Northern members of Congress , General Arnold agreed to accept blacks for pilot training, albeit on

6952-614: The Gulf Coastal Plain in Mexico. In this part of Mexico the following soil types have been shown to be good for cassava cultivation: phaeozem , regosol , arenosol , andosol and luvisol . Before harvest, the leafy stems are removed. The harvest is gathered by pulling up the base of the stem and cutting off the tuberous roots. Cassava deteriorates after harvest, when the tuberous roots are first cut. The healing mechanism produces coumaric acid , which oxidizes and blackens

7110-513: The International Institute of Tropical Agriculture (IITA) under the leadership of Hans Rudolf Herren . The Centre investigated biological control for cassava pests; two South American natural enemies Anagyrus lopezi (a parasitoid wasp) and Typhlodromalus aripo (a predatory mite) were found to effectively control the cassava mealybug and the cassava green mite, respectively. In 2022, world production of cassava root

7268-510: The Lucayans to detoxify cassava is by peeling, grinding, and mashing; filtering the mash through a basket tube to remove the hydrogen cyanide; and drying and sieving the mash for flour. The poisonous filtrate water was boiled to release the hydrogen cyanide, and used as a base for stews. Bioengineering has been applied to grow cassava with lower cyanogenic glycosides combined with fortification of vitamin A , iron and protein to improve

7426-480: The Macushi people of Guyana is closely bound up with the growth and processing of cassava in their slash-and-burn subsistence lifestyle. A story tells that the great spirit Makunaima climbed a tree, cutting off pieces with his axe; when they landed on the ground, each piece became a type of animal. The opossum brought the people to the tree, where they found all the types of food, including bitter cassava. A bird told

7584-624: The Quartermaster Corps and then by the U.S. Army Corps of Engineers , because of a lack of familiarity with Air Corps requirements. The outbreak of war in Europe and the resulting need for a wide variety of facilities for both operations and training within the Continental United States necessitated comprehensive changes of policy, first in September 1941 by giving the responsibility for acquisition and development of bases directly to

7742-690: The United States Air Force , James Robinson Risner and Charles E. Yeager . Air crew needs resulted in the successful training of 43,000 bombardiers , 49,000 navigators , and 309,000 flexible gunners, many of whom also specialized in other aspects of air crew duties. 7,800 men qualified as B-29 flight engineers and 1,000 more as radar operators in night fighters , all of whom received commissions. Almost 1.4 million men received technical training as aircraft mechanics, electronics specialists, and other technicians. Non-aircraft related support services were provided by airmen trained by

7900-657: The vector , Bemisia tabaci whiteflies. Genetically engineered cassava offers opportunities for the improvement of virus resistance, including CMV and CBSD resistance. Among the most serious bacterial pests is Xanthomonas axonopodis pv. manihotis , which causes bacterial blight of cassava . This disease originated in South America and has followed cassava around the world. Bacterial blight has been responsible for near catastrophic losses and famine in past decades, and its mitigation requires active management practices. Several other bacteria attack cassava, including

8058-676: The 16th century. Around the same period, it was introduced to Asia through Columbian Exchange by Portuguese and Spanish traders, who planted it in their colonies in Goa, Malacca, Eastern Indonesia, Timor and the Philippines. Cassava has also become an important crop in Asia. While it is a valued food staple in parts of eastern Indonesia, it is primarily cultivated for starch extraction and bio-fuel production in Thailand, Cambodia and Vietnam. Cassava

8216-605: The AAF created a reserve pool that held qualified pilot candidates until they could be called to active duty, rather than losing them in the draft. By 1944, this pool became surplus, and 24,000 were sent to the Army Ground Forces for retraining as infantry , and 6,000 to the Army Service Forces . Pilot standards were changed to reduce the minimum age from 20 to 18, and eliminated the educational requirement of at least two years of college. Two fighter pilot beneficiaries of this change went on to become brigadier generals in

In addition to the construction of new permanent bases and the building of numerous bombing and gunnery ranges, the AAF utilized civilian pilot schools, training courses conducted at college and factory sites, and officer training detachments at colleges. In early 1942, in

8532-468: The AAF reached a war-time peak of 783 airfields in the Continental United States. At the end of the war, the AAF was using almost 20 million acres of land, an area as large as Massachusetts , Connecticut , Vermont , and New Hampshire combined. By the end of World War II, the USAAF had created 16 numbered air forces ( First through Fifteenth and Twentieth ) distributed worldwide to prosecute

8690-590: The AAF. The huge increases in aircraft inventory resulted in a similar increase in personnel, expanding sixteen-fold in less than three years following its formation, and changed the personnel policies under which the Air Service and Air Corps had operated since the National Defense Act of 1920. No longer could pilots represent 90% of commissioned officers. The need for large numbers of specialists in administration and technical services resulted in

These locations are rotated within the sub-basin they inhabit also interpreted as the same geographical region. The low population density of the traditional communities and their traditional movement of their settlements around their inhabited sub-basin, enable

In some regions vegetations is restricted to growing on average fifteen meters; a result of shallow soils over limestone and strong winds. Flowering and fruiting specimens of Cremastosperma yamayakatense grow up to heights of around 6 to 8 metres in the Cenepa River region in contrast to the Bagua and Condorcanqui provinces where the same species have been recorded having an average of 1.5 meters. A vast number of frog species have been discovered around

9164-529: The Air Corps expanded from 15 to 30 groups by the end of the year. On 7 December 1941 the number of activated combat groups had reached 67, with 49 still within the Continental United States. Of the CONUS groups (the "strategic reserve"), 21 were engaged in operational training or still being organized and were unsuitable for deployment. Of the 67 combat groups, 26 were classified as bombardment: 13 Heavy Bomb groups ( B-17 Flying Fortress and B-24 Liberator ), and

9322-557: The Air Corps found entirely inadequate, naming Arnold as acting "Deputy Chief of Staff for Air" but rejecting all organizational points of his proposal. GHQ Air Force instead was assigned to the control of Army General Headquarters, although the latter was a training and not an operational component, when it was activated in November 1940. A division of the GHQ Air Force into four geographical air defense districts on 19 October 1940

9480-480: The Air Corps in October 1940 saw fifteen new general officer billets created. By the end of World War II, 320 generals were authorized for service within the wartime AAF. The Air Corps operated 156 installations at the beginning of 1941. An airbase expansion program had been underway since 1939, attempting to keep pace with the increase in personnel, units, and aircraft, using existing municipal and private facilities where possible, but it had been mismanaged, first by

9638-490: The Air Corps mission remain tied to that of the land forces. Airpower advocates achieved a centralized control of air units under an air commander, while the WDGS divided authority within the air arm and assured a continuing policy of support of ground operations as its primary role. GHQ Air Force organized combat groups administratively into a strike force of three wings deployed to the Atlantic , Pacific, and Gulf coasts but

American fighter aircraft were inferior to the British Spitfire and Hurricane , and German Messerschmitt Bf 110 and 109 . Ralph Ingersoll wrote in late 1940 after visiting Britain that the "best American fighter planes already delivered to the British are used by them either as advanced trainers—or for fighting equally obsolete Italian planes in

9954-492: The Air Corps years. The concept of an "operating staff", or directorates, was modeled on the RAF system that had been much admired by the observer groups sent over in 1941, and resulted from a desire to place experts in various aspects of military aviation into key positions of implementation. However functions often overlapped, communication and coordination between the divisions failed or was ignored, policy prerogatives were usurped by

10112-458: The Air Corps". A lawyer and a banker, Lovett had prior experience with the aviation industry that translated into realistic production goals and harmony in integrating the plans of the AAF with those of the Army as a whole. Lovett initially believed that President Roosevelt's demand following the attack on Pearl Harbor for 60,000 airplanes in 1942 and 125,000 in 1943 was grossly ambitious. However, working closely with General Arnold and engaging

The peak size of the AAF during World War II was over 2.4 million men and women in service and nearly 80,000 aircraft by 1944, and 783 domestic bases in December 1943. By " V-E Day ", the Army Air Forces had 1.25 million men stationed overseas and operated from more than 1,600 airfields worldwide. The Army Air Forces

Although other nations already had separate air forces independent of their army or navy (such as the Royal Air Force and

10586-508: The Air Corps, while 82 per cent of enlisted members assigned to AAF units and bases had the Air Corps as their combat arm branch. While officially the air arm was the Army Air Forces , the term Air Corps persisted colloquially among the public as well as veteran airmen; in addition, the singular Air Force often crept into popular and even official use, reflected by the designation Air Force Combat Command in 1941–42. This misnomer

10744-496: The Army General Headquarters had the power to detach units from AFCC at will by creating task forces, the WDGS still controlled the AAF budget and finances, and the AAF had no jurisdiction over units of the Army Service Forces providing "housekeeping services" as support nor of air units, bases, and personnel located outside the continental United States. Arnold and Marshall agreed that the AAF would enjoy

Nematode pests of cassava are thought to cause harms ranging from negligible to seriously damaging, making the choice of management methods difficult. A wide range of plant parasitic nematodes have been reported associated with cassava worldwide. These include Pratylenchus brachyurus , Rotylenchulus reniformis , Helicotylenchus spp., Scutellonema spp. and Meloidogyne spp., of which Meloidogyne incognita and Meloidogyne javanica are

During the period of the 1943–1946 aerial survey, two aircraft and 14 men are recorded to be lost in accidents in the dense tropical rainforest encompassing the Cenepa River. A network of rivers and streams as well as brooks follow through deeply dissected mountain systems within

11218-446: The Cenepa River resulted in the greater foot traffic and damages to its ecosystem. In addition with the clearing of tropical premontane rainforests for the establishment of multiple camps and military outposts. The territorial disputes have had many impacts in the Cenepa River as there are reports of landmines from the conflict that remain a problem in that area. The landmines remaining in the upper Cenepa, placed by Peruvian forces add to

11376-409: The Cenepa River which were unknown until this survey. Geographical understanding prior to this survey was limited; the survey verified that the Cenepa River was far longer than Ecuadorian cartography had initially recorded and believed. The Peruvian Government had a spoken pact of mutual understanding and cooperation with the local communities of the Cenepa River, primarily the Aguaruna People. The pact

11534-502: The Cordillera del Condor and Cenepa region are the reason behind the conservation and preservation. The primary role of conservation in the region is to maintain the water cycles essential to the Cenepa River. The 1946 United States Army Air Force accomplished the first aerial survey of the Cordillera del Condor zone including the Cenepa River. The results revealed for the first time the topographic contours, watershed and drainage of

11692-557: The General Staff planned for a wartime activation of an Army general headquarters (GHQ), similar to the American Expeditionary Forces model of World War I , with a GHQ Air Force as a subordinate component. Both were created in 1933 when a small conflict with Cuba seemed possible following a coup d'état but was not activated. The activation of GHQ Air Force represented a compromise between strategic airpower advocates and ground force commanders who demanded that

11850-617: The German Luftwaffe ), the AAF remained a part of the Army until a defense reorganization in the post-war period resulted in the passage by the United States Congress of the National Security Act of 1947 with the creation of an independent United States Air Force in September 1947. In its expansion and conduct of the war, the AAF became more than just an arm of the greater organization. By

12008-474: The HiFi genome assembly revealed extensive chromosome rearrangements and abundant intra-genomic and inter-genomic divergent sequences, with significant structural variations mostly related to long terminal repeat retrotransposons. Although smallholders are otherwise economically inefficient producers, they are vital to productivity at particular times. Small cassava farmers are no exception. Genetic diversity

12166-513: The Low Countries in May 1940, Roosevelt asked Congress for a supplemental appropriation of nearly a billion dollars, a production program of 50,000 aircraft a year, and a military air force of 50,000 aircraft (of which 36,500 would be Army). Accelerated programs followed in the Air Corps that repeatedly revised expansion goals, resulting in plans for 84 combat groups, 7,799 combat aircraft, and

12324-527: The Middle East. That is all they are good for." RAF crews he interviewed said that by spring 1941 a fighter engaging Germans had to have the capability to reach 400 mph in speed, fight at 30,000–35,000 feet, be simple to take off, provide armor for the pilot, and carry 12 machine guns or six cannons, all attributes lacking in American aircraft. Following the successful German invasion of France and

12482-543: The Office of Chief of the Air Corps (OCAC), eliminating all its training and organizational functions, which removed an entire layer of authority. Taking their former functions were eleven numbered air forces (later raised to sixteen) and six support commands (which became eight in January 1943). The circular also restated the mission of the AAF, in theory removing from it responsibility for strategic planning and making it only

12640-762: The United States . The AAF was a component of the United States Army , which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces , the United States Army Services of Supply (which in 1943 became the Army Service Forces ), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff . The AAF administered all parts of military aviation formerly distributed among

12798-545: The WAACs and WACs as AAF personnel, more than 1,000 as Women Airforce Service Pilots (WASPs), and 6,500 as nurses in the Army Air Forces, including 500 flight nurses. 7,601 "Air WACs" served overseas in April 1945, and women performed in more than 200 job categories. The Air Corps Act of July 1926 increased the number of general officers authorized in the Army's air arm from two to four. The activation of GHQAF in March 1935 doubled that number to eight and pre-war expansion of

12956-430: The air forces and to avoid binding legislation from Congress, the War Department revised the army regulation governing the organization of Army aviation, AR 95–5. Arnold assumed the title of Chief of the Army Air Forces , creating an echelon of command over all military aviation components for the first time and ending the dual status of the Air Corps and GHQ Air Force, which was renamed Air Force Combat Command (AFCC) in

13114-473: The air forces, commands and divisions were administrative headquarters called wings to control groups (operational units; see section below). As the number of groups increased, the number of wings needed to control them multiplied, with 91 ultimately activated, 69 of which were still active at the end of the war. As part of the Air Service and Air Corps, wings had been composite organizations, that is, composed of groups with different types of missions. Most of

13272-481: The annual addition to the force of 30,000 new pilots and 100,000 technical personnel. The accelerated expansion programs resulted in a force of 156 airfields and 152,125 personnel at the time of the creation of the Army Air Forces. In its expansion during World War II, the AAF became the world's most powerful air force. From the Air Corps of 1939, with 20,000 men and 2,400 planes, to the nearly autonomous AAF of 1944, with almost 2.4 million personnel and 80,000 aircraft,

13430-471: The army and the Aguaruna resulted in the army receiving warnings from the locals, regarding military infiltrations from Ecuadorian forces. As the Cenepa River along the border is a region of extremely restricted access, traditional dirt roads is the one alternative option other than a helicopter flight. The Team, Organisation for the Development of Border Communities of EL Cenepa Research 2010 observed that

13588-540: The basin, primarily in habitats that consisted of clear and black waters, including some lentic environments. It was observed that there is a great Otter presence in the region, this highlights the copiousness of fish in the upper stretches of the Cenepa river basin.

13746-469: The bitter varieties containing much larger amounts. The more toxic varieties of cassava have been used in some places as famine food during times of food insecurity . For example, during the shortages in Venezuela in the late 2010s, dozens of deaths were reported due to Venezuelans resorting to eating bitter cassava in order to curb starvation. Cases of cassava poisoning were also documented during

13904-522: The capacity of the American automotive industry brought about an effort that produced almost 100,000 aircraft in 1944. The AAF reached its wartime inventory peak of nearly 80,000 aircraft in July 1944, 41% of them first line combat aircraft, before trimming back to 73,000 at the end of the year following a large reduction in the number of trainers needed. The logistical demands of this armada were met by

14062-430: The capitulation of Japan, realignment took place with the complete elimination of OC&R. The now five assistant chiefs of air staff were designated AC/AS-1 through -5 corresponding to Personnel, Intelligence, Operations and Training, Materiel and Supply, and Plans. Most personnel of the Army Air Forces were drawn from the Air Corps. In May 1945, 88 per cent of officers serving in the Army Air Forces were commissioned in

14220-435: The case of both farofa and garri ). Cassava is the third-largest source of carbohydrates in food in the tropics, after rice and maize , making it an important staple ; more than 500 million people depend on it. It offers the advantage of being exceptionally drought-tolerant , and able to grow productively on poor soil. The largest producer is Nigeria, while Thailand is the largest exporter of cassava starch. Cassava

14378-538: The cassava enzyme linamarase , releasing poisonous hydrogen cyanide . Cassava varieties are often categorized as either bitter (high in cyanogenic glycosides) or sweet (low in those bitter compounds). Sweet cultivars can contain as little as 20 milligrams of cyanide per kilogram of fresh roots, whereas bitter cultivars may contain as much as 1000 milligrams per kilogram. Cassavas grown during drought are especially high in these toxins. A dose of 25 mg of pure cassava cyanogenic glucoside, which contains 2.5 mg of cyanide,

14536-518: The commanders of GHQ Air Force and the Air Corps, Major Generals Frank M. Andrews and Oscar Westover respectively, clashed philosophically over the direction in which the air arm was moving, exacerbating the difficulties. The expected activation of Army General Headquarters prompted Army Chief of Staff George C. Marshall to request a reorganization study from Chief of the Air Corps Maj. Gen. Henry H. Arnold resulting on 5 October 1940 in

14694-573: The commanding generals of the new Army Ground Forces and Services of Supply , the other two components of the Army of the United States . The War Department issued Circular No. 59 on 2 March that carried out the executive order, intended (as with the creation of the Air Service in World War I) as a wartime expedient to expire six months after the end of the war. The three components replaced

14852-512: The common name "manioc" both derive from the Guarani (Tupi) name mandioca or manioca for the plant. The specific name esculenta is Latin for 'edible'. The common name "cassava" is a 16th century word from the French or Portuguese cassave , in turn from Taíno caçabi . The common name "yuca" or "yucca" is most likely also from Taíno, via Spanish yuca or juca . The harvested part of

15010-399: The community. Bananas, cassava , plantains and Mauritian palm fruit are the most common food resources grown in the Cenepa river basin that the local communities eat, where meals are most commonly prepared through boiling. The land around the Cenepa River has many banana trees, maintained by the local communities. Chapo and pururuca are the names of drinks the local communities, primarily

15168-700: The conduct of all aspects of the air war in every part of the world, determining air policy and issuing orders without transmitting them through the Army Chief of Staff. This "contrast between theory and fact is...fundamental to an understanding of the AAF." The roots of the Army Air Forces arose in the formulation of theories of strategic bombing at the Air Corps Tactical School that gave new impetus to arguments for an independent air force, beginning with those espoused by Brig. Gen. Billy Mitchell that led to his later court-martial . Despite

15326-625: The creation of the Air Service Command on 17 October 1941 to provide service units and maintain 250 depots in the United States; the elevation of the Materiel Division to full command status on 9 March 1942 to develop and procure aircraft, equipment, and parts; and the merger of these commands into the Air Technical Service Command on 31 August 1944. In addition to carrying personnel and cargo,

15484-634: The creation of the Army Air Forces, caused an immediate reassessment of U.S. defense strategy and policy. The need for an offensive strategy to defeat the Axis Powers required further enlargement and modernization of all the military services, including the new AAF. In addition, the invasion produced a new Lend lease partner in Russia, creating even greater demands on an already struggling American aircraft production. An offensive strategy required several types of urgent and sustained effort. In addition to

15642-448: The development and manufacture of aircraft in massive numbers, the Army Air Forces had to establish a global logistics network to supply, maintain, and repair the huge force; recruit and train personnel; and sustain the health, welfare, and morale of its troops. The process was driven by the pace of aircraft production, not the training program, and was ably aided by the direction of Lovett, who for all practical purposes became "Secretary of

15800-469: The direct control of Headquarters Army Air Forces. At the end of 1942 and again in the spring of 1943 the AAF listed nine support commands before it began a process of consolidation that streamlined the number to five at the end of the war. These commands were: "In 1943 the AAF met a new personnel problem, to which it applied an original solution: to interview, rehabilitate, and reassign men returning from overseas. [To do this], an AAF Redistribution Center

15958-620: The directorates, and they became overburdened with detail, all contributing to the diversion of the directorates from their original purpose. The system of directorates in particular handicapped the developing operational training program (see Combat units below), preventing establishment of an OTU command and having a tendency to micromanage because of the lack of centralized control. Four main directorates—Military Requirements, Technical Services, Personnel, and Management Control—were created, each with multiple sub-directorates, and eventually more than thirty offices were authorized to issue orders in

16116-447: The dormant struggle for an independent United States Air Force. Marshall had come to the view that the air forces needed a "simpler system" and a unified command. Working with Arnold and Robert A. Lovett , recently appointed to the long-vacant position of Assistant Secretary of War for Air, he reached a consensus that quasi-autonomy for the air forces was preferable to immediate separation. On 20 June 1941, to grant additional autonomy to

16274-571: The end of World War II, the Army Air Forces had become virtually an independent service. By regulation and executive order, it was a subordinate agency of the United States Department of War (as were the Army Ground Forces and the Army Service Forces) tasked only with organizing, training, and equipping combat units and limited in responsibility to the continental United States. In reality, Headquarters AAF controlled

16432-671: The equator, where it can be produced at up to 2,000 m (7,000 ft) above sea level, and with 50 to 5,000 mm (2 to 200 in) of rain per year. These environmental tolerances suit it to conditions across much of South America and Africa. Cassava yields a large amount of food energy per unit area of land per day – 1,000,000 kJ/ha (250,000 kcal/ha), as compared with 650,000 kJ/ha (156,000 kcal/ha) for rice, 460,000 kJ/ha (110,000 kcal/ha) for wheat and 840,000 kJ/ha (200,000 kcal/ha) for maize. Cassava, yams ( Dioscorea spp.), and sweet potatoes ( Ipomoea batatas ) are important sources of food in

16590-555: The establishment of an Officer Candidate School in Miami Beach, Florida , and the direct commissioning of thousands of professionals. Even so, 193,000 new pilots entered the AAF during World War II, while 124,000 other candidates failed at some point during training or were killed in accidents. The requirements for new pilots resulted in a massive expansion of the Aviation Cadet program, which had so many volunteers that

16748-626: The famine accompanying the Great Leap Forward (1958–1962) in China. Farmers may select bitter cultivars to reduce crop losses. Societies that traditionally eat cassava generally understand that processing (soaking, cooking, fermentation, etc.) is necessary to avoid getting sick. Brief soaking (four hours) of cassava is not sufficient, but soaking for 18–24 hours can remove up to half the level of cyanide. Drying may not be sufficient, either. For some smaller-rooted, sweet varieties, cooking

16906-682: The famous iconic " Why We Fight " series, as an animated map graphic of equal prominence to that of the Army and Navy. The Air Corps at the direction of President Roosevelt began a rapid expansion from the spring of 1939 forward, partly from the Civilian Pilot Training Program created at the end of 1938, with the goal of providing an adequate air force for defense of the Western Hemisphere. An initial "25-group program", announced in April 1939, called for 50,000 men. However, when war broke out in September 1939

17064-524: The first Cuban industry established by the Spanish. Ships departing to Europe from Cuban ports such as Havana , Santiago , Bayamo , and Baracoa carried goods to Spain, but sailors needed to be provisioned for the voyage. The Spanish also needed to replenish their boats with dried meat, water, fruit, and large amounts of cassava bread. Sailors complained that it caused them digestive problems. Portuguese traders introduced cassava to Africa from Brazil in

17222-422: The flavors and also impart them (even if dry) to foods such as rice and chicken cooked in it. The poisonous but volatile hydrogen cyanide is evaporated by heating. Nevertheless, improperly cooked cassava has been blamed for a number of deaths. Amerindians from Guyana reportedly made an antidote by steeping chili peppers in rum . The natives of Guyana traditionally brought the product to town in bottles, and it

17380-466: The force array. In the first half of 1942 the Army Air Forces expanded rapidly as the necessity of a much larger air force than planned was immediately realized. Authorization for the total number of combat groups required to fight the war nearly doubled in February to 115. In July it jumped to 224, and a month later to 273. When the U.S. entered the war, however, the number of groups actually trained to

17538-660: The ground forces by March 1942. In the spring of 1941, the success in Europe of air operations conducted under centralized control (as exemplified by the British Royal Air Force and the German Wehrmacht 's military air arm, the Luftwaffe ) made clear that the splintering of authority in the American air forces, characterized as " hydra -headed" by one congressman, had caused a disturbing lack of clear channels of command. Less than five months after

17696-428: The increasing formation of new population centres and existing communities consisting of relatives that lived traditionally in a widespread manner. The increasing populations concentrated around the lower and middle regions of the Cenepa and Canga rivers. The main populous communities are located in the middle reaches of the river. The increase in schools and other services to the region such as health posts has resulted in

17854-416: The integrity of the Cenepa River Basin. Overall, the legal certainty of the Cenepa River was an effort to recognise the traditional caretakers of the land. The Team, Organisation for the Development of Border Communities of EL Cenepa Research states that "by 1999 a total of 158, 910 hectares in the Cenepa River Basin had been awarded land tiles to the local communities". The Cenepa River native inhabitants are

18012-715: The leaves are rich in it, except for being low in methionine , an essential amino acid . The complete and haplotype-resolved African cassava (TME204) genome has been reconstructed and made available using the Hi-C technology. The genome shows abundant novel gene loci with enriched functionality related to chromatin organization, meristem development, and cell responses. Differentially expressed transcripts of different haplotype origins were enriched for different functionality during tissue development. In each tissue, 20–30% of transcripts showed allele-specific expression differences with <2% of direction-shifting. Despite high gene synteny,

18170-463: The leaves of the cassava plant to wither, limiting the growth of the root. An outbreak of the virus in Africa in the 1920s led to a major famine. The virus is spread by the whitefly and by the transplanting of diseased plants into new fields. Sometime in the late-1980s, a mutation occurred in Uganda that made the virus even more harmful, causing the complete loss of leaves. This mutated virus spread at

18328-404: The locations of where the bilingual schools had been established in the 1960s". These communities where primarily located in the middle reaches of the Cenepa river including some in the lower reaches. The land tiles were given to fourteen local communities and had the common attempt to protect the land on the banks of the Cenepa river that were in the local vicinity of the established schools. This

18486-497: The most widely reported and economically important. Meloidogyne spp. feeding produces physically damaging galls with eggs inside them. Galls later merge as the females grow and enlarge, and they interfere with water and nutrient supply. Cassava roots become tough with age and restrict the movement of the juveniles and the egg release. It is therefore possible that extensive galling can be observed even at low densities following infection. Other pests and diseases can gain entry through

18644-550: The name of the commanding general. Among the headquarters directorates were Technical Services, Air Defense, Base Services, Ground-Air Support, Management Control, Military Equipment, Military Requirements , and Procurement & Distribution. A "strong and growing dissatisfaction" with the organization led to an attempt by Lovett in September 1942 to make the system work by bringing the Directorate of Management Control and several traditional offices that had been moved to

18802-402: The new organization. The AAF gained the formal "Air Staff" long opposed by the General Staff, and a single air commander, but still did not have equal status with the Army ground forces, and air units continued to report through two chains of command. The commanding general of AFCC gained control of his stations and court martial authority over his personnel, but under the new field manual FM-5

18960-412: The nutrition of people in sub-Saharan Africa. In Guyana the traditional cassareep is made from bitter cassava juice. The juice is boiled until it is reduced by half in volume, to the consistency of molasses and flavored with spices —including cloves , cinnamon , salt , sugar , and cayenne pepper . Traditionally, cassareep was boiled in a soft pot, the actual "pepper pot", which would absorb

19118-479: The operating staff, including the Air Judge Advocate and Budget Officer, back under the policy staff umbrella. When this adjustment failed to resolve the problems, the system was scrapped and all functions combined into a single restructured air staff. The hierarchical "command" principle, in which a single commander has direct final accountability but delegates authority to staff, was adopted AAF-wide in

19276-961: The operational command was designated by the Roman numeral of its parent numbered air force. For instance, the Eighth Air Force listed the VIII Bomber Command and the VIII Fighter Command as subordinate operational commands. Roman numbered commands within numbered air forces also included "support", "base", and other services commands to support the operational units, such as the VIII Air Force Service and VIII Air Force Composite Commands also part of Eighth Air Force during its history. The Tenth and Fourteenth Air Forces did not field subordinate commands during World War II. Fifteenth Air Force organized

19434-569: The pact was the reason that the valleys in the Cenepa River Basin had no outside settlements and it was made possible to sustain territorial control and environment solidity for the traditional locals. Large troop activity around the Cenepa River was evident during the disputes between Ecuador and Peru. In 1995, upwards of 3000 Ecuadorian troops where deployed in the region as well as 2000 Peruvian troops. The average skirmishes between these forces where between patrol units consisting of on average 40 men (Marcella 1995 p. 1). Increased troop activity around

19592-457: The patient's body to detoxify by converting the poisonous cyanide into thiocyanate). Chronic, low-level exposure to cyanide may contribute to both goiter and tropical ataxic neuropathy , also called konzo , which can be fatal. The risk is highest in famines, when as many as 3 percent of the population may be affected. Like many other roots and tubers, both bitter and sweet varieties of cassava contain antinutritional factors and toxins, with

19750-548: The physical damage caused by gall formation, leading to rots. They have not been shown to cause direct damage to the enlarged tuberous roots, but plant height can be reduced if the root system is reduced. Nematicides reduce the numbers of galls per feeder root, along with fewer rots in the tuberous roots. The organophosphorus nematicide femaniphos does not reduce crop growth or harvest yield. Nematicide use in cassava does not increase harvested yield significantly, but lower infestation at harvest and lower subsequent storage loss provide

19908-439: The population around the Cenepa River to rise. The Team Organisation for the Development of Border Communities of EL Cenepa Research 2010 states that the sizes of the local communities greatly varied from 50 to 3000 inhabitants. This resulted in the increase of small farms for animal breeding which was located closer to the local communities and farmland for food production through crops such as bananas and cocoa, located further from

20066-524: The proposal the following month which, in the face of Marshall's dissatisfaction with Army GHQ, the War Plans Division accepted. Just before Pearl Harbor, Marshall recalled an Air Corps officer, Brig. Gen. Joseph T. McNarney , from an observer group in England and appointed him to chair a "War Department Reorganization Committee" within the War Plans Division, using Arnold's and Spaatz's plan as

20224-554: The regions. The water that originates in the Cordillera del Condor establishes a pivotal section of the subsystems that create the Cenepa river basin. The great multitude of limestone and sandstone structure in the region along with the presence of the vast number of streams have created hundreds of culturally significant waterfalls in the Cordillera del Condor and Cenepa regions. Caves which have been formed can take days to walk through, these are accessed through long narrow passages that are often 60 to 80 meters deep. These characteristics of

20382-442: The rejection of Arnold's reorganization proposal, a joint U.S.-British strategic planning agreement ( ABC-1 ) refuted the General Staff's argument that the Air Corps had no wartime mission except to support ground forces. A struggle with the General Staff over control of air defense of the United States had been won by airmen and vested in four command units called "numbered air forces", but the bureaucratic conflict threatened to renew

20540-630: The related Xanthomonas campestris pv. cassavae , which causes bacterial angular leaf spot. Several fungi bring about significant crop losses, one of the most serious being cassava root rot; the pathogens involved are species of Phytophthora , the genus which causes potato blight. Cassava root rot can result in losses of as much as 80 percent of the crop. A major pest is a rust caused by Uromyces manihotis . Superelongation disease, caused by Elsinoë brasiliensis , can cause losses of over 80 percent of young cassava in Latin America and

20698-442: The relevant DV). Cassava has been studied as a feedstock to produce ethanol as a biofuel , including to improve the efficiency of conversion from cassava flour, and to convert crop residues such as stems and leaves as well as the more easily processed roots. China has created facilities to produce substantial amounts of ethanol fuel from cassava roots. Cassava tubers and hay are used worldwide as animal feed. Young cassava hay

20856-410: The reproductive organs, as shown by experimental overexpression reducing storage root accumulation. Wild populations of M. esculenta subspecies flabellifolia , shown to be the progenitor of domesticated cassava, are centered in west-central Brazil, where it was likely first domesticated no more than 10,000 years ago. Forms of the modern domesticated species can also be found growing in the wild in

21014-488: The rest Medium and Light groups ( B-25 Mitchell , B-26 Marauder , and A-20 Havoc ). The balance of the force included 26 Pursuit groups (renamed fighter group in May 1942), 9 Observation (renamed Reconnaissance ) groups, and 6 Transport (renamed Troop Carrier or Combat Cargo ) groups. After the operational deployment of the B-29 Superfortress bomber, Very Heavy Bombardment units were added to

21172-524: The role of the Army Air Forces, Arnold was given a seat on the Joint Chiefs of Staff , the planning staff that served as the focal point of American strategic planning during the war, in order that the United States would have an air representative in staff talks with their British counterparts on the Combined Chiefs . In effect the head of the AAF gained equality with Marshall. While this step

21330-488: The roots, making them inedible after a few days. This deterioration is related to the accumulation of reactive oxygen species initiated by cyanide release during mechanical harvesting. Cassava shelf life may be increased up to three weeks by overexpressing a cyanide-insensitive alternative oxidase, which suppressed ROS by 10-fold. Post-harvest deterioration is a major obstacle to the export of cassava. Fresh cassava can be preserved like potato, using thiabendazole or bleach as

21488-490: The significant dangers of the region. Airstrikes have impacted areas around the Cenepa river, primarily in east Cordillera del Condor. The Cenepa River Basin has been the subject to territorial disputes between Ecuador and Peru as well as legal conflicts between the local inhabitants and the Peruvian government. In the 1970s the "first registrations and land titles where awarded to the communities that roughly corresponded to

21646-510: The soil fertility to periodically recover. This allows the Aguarana people to maintain the land and resources such as fruit trees. The traditional local communities main influence on the Cenepa River region was the continual rotation of their settlements which provided the basin the opportunity to recover and be maintained. In the 1960s the first bilingual schools were established in the Cenepa River Basin region. this establishment contributed to

21804-702: The south of Brazil. By 4600 BC, cassava pollen appears in the Gulf of Mexico lowlands, at the San Andrés archaeological site. The oldest direct evidence of cassava cultivation comes from a 1,400-year-old Maya site, Joya de Cerén , in El Salvador . It became a staple food of the native populations of northern South America, southern Mesoamerica, and the Taino people in the Caribbean islands , who grew it using

21962-402: The sweet variety is mild to the taste, like potatoes; Jewish households sometimes use it in cholent . It can be made into a flour that is used in breads, cakes and cookies. In Brazil, farofa , a dry meal made from cooked powdered cassava, is roasted in butter, eaten as a side dish, or sprinkled on other food. In Taiwanese culture, now spread to the United States, cassava "juices" are dried to

22120-446: The tropics. The cassava plant gives the third-highest yield of carbohydrates per cultivated area among crop plants, after sugarcane and sugar beets . Cassava plays a particularly important role in agriculture in developing countries, especially in sub-Saharan Africa , because it does well on poor soils and with low rainfall, and because it is a perennial that can be harvested as required. Its wide harvesting window allows it to act as

22278-494: The war, plus a general air force within the continental United States to support the whole and provide air defense. The latter was formally organized as the Continental Air Forces and activated on 15 December 1944, although it did not formally take jurisdiction of its component air forces until the end of the war in Europe. Half of the numbered air forces were created de novo as the service expanded during

22436-461: The war-time Army Air Forces. The AAF was willing to experiment with its allotment from the unpopular Women's Army Auxiliary Corps (WAACs) and became an early and determined supporter of full military status for women in the Army ( Women's Army Corps or WACs). WACs serving in the AAF became such an accepted and valuable part of the service they earned the distinction of being commonly (but unofficially) known as "Air WACs". Nearly 40,000 women served in

22594-630: The war. Some grew out of earlier commands as the service expanded in size and hierarchy (for example, the V Air Support Command became the Ninth Air Force in April 1942), and higher echelons such as United States Strategic Air Forces (USSTAF) in Europe and U.S. Strategic Air Forces in the Pacific became necessary to control the whole. Within numbered air forces, operational commands were created to divide administrative control of units by function (eg fighters and bombers). The numbering of

22752-419: The water during the soaking process are also used in cooking. The flour is used throughout South America and the Caribbean . Industrial production of cassava flour, even at the cottage level, may generate enough cyanide and cyanogenic glycosides in the effluents to have a severe environmental impact. There are many ways of cooking cassava . It has to be prepared correctly to remove its toxicity. The root of

22910-404: The wings of World War II, however, were composed of groups with like functions (denoted as bombardment , fighter , reconnaissance , training , antisubmarine , troop carrier , and replacement ). The six support commands organized between March 1941 and April 1942 to support and supply the numbered air forces remained on the same chain of command echelon as the numbered air forces, under

23068-469: Was 330 million tonnes, led by Nigeria with 18% of the total (table). Other major growers were Democratic Republic of the Congo and Thailand. Cassava is the third-largest source of carbohydrates in food in the tropics, after rice and maize . making it an important staple; more than 500 million people depend on it. It offers the advantage of being exceptionally drought-tolerant , and able to grow productively on poor soil. Cassava grows well within 30° of

23226-622: Was a remarkable expansion. Robert A. Lovett, the Assistant Secretary of War for Air, together with Arnold, presided over an increase greater than for either the ground Army or the Navy, while at the same time dispatching combat air forces to the battlefronts. "The Evolution of the Department of the Air Force" – Air Force Historical Studies Office The German invasion of the Soviet Union , occurring only two days after

23384-542: Was also used on official recruiting posters (see image above) and was important in promoting the idea of an "Air Force" as an independent service. Jimmy Stewart , a Hollywood movie star serving as an AAF pilot, used the terms "Air Corps" and "Air Forces" interchangeably in the narration of the 1942 recruiting short " Winning Your Wings " . The term "Air Force" also appeared prominently in Frank Capra 's 1945 War Department indoctrination film " War Comes to America " , of

23542-581: Was concurrent with the creation of air forces to defend Hawaii and the Panama Canal . The air districts were converted in March 1941 into numbered air forces with a subordinate organization of 54 groups. The likelihood of U.S. participation in World War II prompted the most radical reorganization of the aviation branch in its history, developing a structure that both unified command of all air elements and gave it total autonomy and equality with

23700-457: Was created in June 1941 to provide the air arm greater autonomy in which to expand more efficiently, to provide a structure for the additional command echelons required by a vastly increased force, and to end an increasingly divisive administrative battle within the Army over control of aviation doctrine and organization that had been ongoing since the creation of an aviation section within the U.S. Army Signal Corps in 1914. The AAF succeeded both

23858-503: Was enforced in 1940 by the military and remained until the end of the Cenepa War in 1995. As a result of the local communities' ability to produce food resources through small farms like animal breeding ; such as chickens and farmland for bananas . This enabled the army to maintain logistical support through a reliable and steady supply of staples from the locals for their encampments established in isolated locations. The pact between

24016-498: Was established on 7 August 1943, and given command status on 1 June 1944. as the AAF Personnel Distribution Command. This organization was ordered discontinued, effective 30 June 1946." The primary combat unit of the Army Air Forces for both administrative and tactical purposes was the group , an organization of three or four flying squadrons and attached or organic ground support elements, which

24174-403: Was in order to protect and preserve the local communities' right to fish and pan for alluvial gold. Including the right of access and ownership of inland areas. The end of the Cenepa War of 1995 was when the legal certainty of the land was recognised as an important verdict. Results were produced between 1997 and 1999, where many local Cenepa River communities were granted land titles as to maintain

24332-502: Was never officially recognized by the United States Navy , and was bitterly disputed behind the scenes at every opportunity, it nevertheless succeeded as a pragmatic foundation for the future separation of the Air Force. Under the revision of AR 95–5, the Army Air Forces consisted of three major components: Headquarters AAF, Air Force Combat Command, and the Air Corps. Yet the reforms were incomplete, subject to reversal with

24490-464: Was small in comparison to European air forces. Lines of authority were difficult, at best, since GHQ Air Force controlled only operations of its combat units while the Air Corps was still responsible for doctrine, acquisition of aircraft, and training. Corps area commanders continued to exercise control over airfields and administration of personnel, and in the overseas departments, operational control of units as well. Between March 1935 and September 1938,

24648-404: Was the major land-based aerial warfare service component of the United States Army and de facto aerial warfare service branch of the United States during and immediately after World War II (1941–1947). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force , today one of the six armed forces of

24806-460: Was the rough equivalent of a regiment of the Army Ground Forces . The Army Air Forces fielded a total of 318 combat groups at some point during World War II, with an operational force of 243 combat groups in 1945. The Air Service and its successor the Air Corps had established 15 permanent combat groups between 1919 and 1937. With the buildup of the combat force beginning 1 February 1940,

24964-502: Was threatened. Cassava Manihot esculenta , commonly called cassava , manioc , or yuca (among numerous regional names), is a woody shrub of the spurge family, Euphorbiaceae , native to South America, from Brazil, Paraguay and parts of the Andes. Although a perennial plant, cassava is extensively cultivated in tropical and subtropical regions as an annual crop for its edible starchy tuberous root. Cassava
