129-467: The River Moriston ( Scottish Gaelic : Abhainn Mhoireastain ) is a river in Inverness-shire , Scotland. It flows broadly east-north-east from the outfall of the dam at Loch Cluanie to Loch Ness . Its waters and those of its tributaries have been harnessed to generate hydro-electric power . The River Moriston begins just below the dam at the eastern end of Loch Cluanie. Flow in the river

258-442: A 19% fall in bilingual speakers between the 1911 and 1921 Censuses. Michelle MacLeod of Aberdeen University has said that there was no other period with such a high fall in the number of monolingual Gaelic speakers: "Gaelic speakers became increasingly the exception from that point forward with bilingualism replacing monolingualism as the norm for Gaelic speakers." The Linguistic Survey of Scotland (1949–1997) surveyed both

387-557: A Goidelic language, Scottish Gaelic, as well as both Irish and Manx , developed out of Old Irish . It became a distinct spoken language sometime in the 13th century in the Middle Irish period, although a common literary language was shared by the Gaels of both Ireland and Scotland until well into the 17th century. Most of modern Scotland was once Gaelic-speaking, as evidenced especially by Gaelic-language place names. In

516-564: A Pictish substrate. In 1018, after the conquest of Lothian (theretofore part of England and inhabited predominantly by speakers of Northumbrian Old English ) by the Kingdom of Scotland , Gaelic reached its social, cultural, political, and geographic zenith. Colloquial speech in Scotland had been developing independently of that in Ireland since the eighth century. For the first time,

645-405: A blend containing ground limestone (where a suffix L is present in the class names). White portland cement or white ordinary portland cement (WOPC) is similar to ordinary gray portland cement in all respects, except for its high degree of whiteness. Obtaining this colour requires high purity raw materials (low Fe 2 O 3 content), and some modification to the method of manufacture, among others

774-534: A cement of the kind invented 7 years later by the French engineer Louis Vicat . Vicat's cement is an artificial hydraulic lime , and is considered the "principal forerunner" of portland cement. The name portland cement is recorded in a directory published in 1823 being associated with a William Lockwood and possibly others. In his 1824 cement patent, Joseph Aspdin called his invention "portland cement" because of its resemblance to Portland stone . Aspdin's cement

903-524: A central feature of court life there. The semi-independent Lordship of the Isles in the Hebrides and western coastal mainland remained thoroughly Gaelic since the language's recovery there in the 12th century, providing a political foundation for cultural prestige down to the end of the 15th century. By the mid-14th century what eventually came to be called Scots (at that time termed Inglis ) emerged as

1032-823: A challenge to revitalization efforts which occur outside the home. Positive engagements between language learners and native speakers of Gaelic through mentorship has proven to be productive in socializing new learners into fluency. In the 2022 census, 3,551 people claimed Gaelic as their 'main language.' Of these, 1,761 (49.6%) were in Na h-Eileanan Siar, 682 (19.2%) were in Highland, 369 were in Glasgow City and 120 were in City of Edinburgh; no other council area had as many as 80 such respondents. Gaelic has long suffered from its lack of use in educational and administrative contexts and

1161-465: A construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element. Concrete can be used in the construction of structural elements like panels, beams, and street furniture , or may be cast- in situ for superstructures like roads and dams. These may be supplied with concrete mixed on site, or may be provided with ' ready-mixed ' concrete made at permanent mixing sites. Portland cement

1290-400: A few weeks and this causes strength growth to stop. Five types of portland cements exist, with variations of the first three according to ASTM C150. Type I portland cement is known as common or general-purpose cement. It is generally assumed unless another type is specified. It is commonly used for general construction, especially when making precast, and precast-prestressed concrete that

1419-489: A full range of language skills: speaking, understanding, reading and writing Gaelic. 40.2% of Scotland's Gaelic speakers said that they used Gaelic at home. To put this in context, the most common language spoken at home in Scotland after English and Scots is Polish, with about 1.1% of the population, or 54,000 people. The 2011 UK Census showed a total of 57,375 Gaelic speakers in Scotland (1.1% of population over three years old), of whom only 32,400 could also read and write

1548-487: A fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker. The materials in cement clinker are alite, belite, tricalcium aluminate , and tetracalcium alumino ferrite. The aluminium, iron, and magnesium oxides are present as a flux allowing the calcium silicates to form at a lower temperature, and contribute little to the strength. For special cements, such as low heat (LH) and sulphate resistant (SR) types, it

1677-514: A given project it is best to use cement from a single batch. Bags of cement routinely have health and safety warnings printed on them, because not only is cement highly alkaline , but the setting process is also exothermic . As a result, wet cement is strongly caustic and can easily cause severe skin burns if not promptly washed off with water. Similarly, dry cement powder in contact with mucous membranes can cause severe eye or respiratory irritation. The reaction of cement dust with moisture in

1806-405: A higher kiln temperature required to sinter the clinker in the absence of ferric oxides acting as a flux in normal clinker. As Fe 2 O 3 contributes to decrease the melting point of the clinker (normally 1450 °C), the white cement requires a higher sintering temperature (around 1600 °C). Because of this, it is somewhat more expensive than the grey product. The main requirement is to have

1935-586: A language ideology at odds with revitalization efforts on behalf of new speakers, state policies (such as the Gaelic Language Act), and family members reclaiming their lost mother tongue. New learners of Gaelic often have a positive affective stance to their language learning, and connect this learning journey towards Gaelic language revitalization. The mismatch of these language ideologies, and differences in affective stance, has led to fewer speaking opportunities for adult language learners and therefore

2064-527: A low iron content which should be less than 0.5 wt.% expressed as Fe 2 O 3 for white cement, and less than 0.9 wt.% for off-white cement. It also helps to have the iron oxide as ferrous oxide (FeO) which is obtained via slightly reducing conditions in the kiln, i.e., operating with zero excess oxygen at the kiln exit. This gives the clinker and cement a green tinge. Other metallic oxides such as Cr 2 O 3 (green), MnO (pink), TiO 2 (white), etc., in trace content, can also give colour tinges, so for

2193-633: A mild heat. The European norm EN 197-1 defines five classes of common cement that comprise portland cement as a main constituent. These classes differ from the ASTM classes. * Constituents that are permitted in portland-composite cements are artificial pozzolans (blast furnace slag (in fact a latent hydraulic binder), silica fume, and fly ashes), or natural pozzolans (siliceous or siliceous aluminous materials such as volcanic ash glasses, calcined clays and shale). The Canadian standards describe six main classes of cement, four of which can also be supplied as

2322-805: A national centre for Gaelic Language and Culture, based in Sleat , on the Isle of Skye . This institution is the only source for higher education which is conducted entirely in Scottish Gaelic. They offer courses for Gaelic learners from beginners into fluency. They also offer regular bachelors and graduate programs delivered entirely in Gaelic. Concerns have been raised around the fluency achieved by learners within these language programs because they are disconnected from vernacular speech communities. In regard to language revitalization planning efforts, many feel that

2451-480: A patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s. The low cost and widespread availability of the limestone, shales , and other naturally occurring materials used in portland cement make it a relatively cheap building material. Its most common use is in the production of concrete, a composite material consisting of aggregate (gravel and sand), cement, and water. Portland cement

2580-549: A process of Gaelicisation (which may have begun generations earlier) was clearly under way during the reigns of Caustantín and his successors. By a certain point, probably during the 11th century, all the inhabitants of Alba had become fully Gaelicised Scots, and Pictish identity was forgotten. Bilingualism in Pictish and Gaelic, prior to the former's extinction, led to the presence of Pictish loanwords in Gaelic and syntactic influence which could be considered to constitute

2709-610: A proportion of Gaelic speakers greater than 65% (the highest value is in Barvas , Lewis , with 64.1%). In addition, no civil parish on mainland Scotland has a proportion of Gaelic speakers greater than 20% (the highest is in Ardnamurchan , Highland , with 19.3%). Out of a total of 871 civil parishes in Scotland, the proportion of Gaelic speakers exceeds 50% in seven parishes, 25% in 14 parishes, and 10% in 35 parishes. Decline in traditional areas has recently been balanced by growth in

2838-536: A situation where new learners struggle to find opportunities to speak Gaelic with fluent speakers. Affect is the way people feel about something, or the emotional response to a particular situation or experience. For Gaelic speakers, there is a conditioned and socialized negative affect through a long history of negative Scottish media portrayal and public disrespect, state mandated restrictions on Gaelic usage, and highland clearances . This negative affect towards speaking openly with non-native Gaelic speakers has led to

2967-465: A smaller generator in the station, which can discharge compensation water to the river when the full capacity of the station is not required. In addition to the main supply from Loch Cluanie, water from the upper reaches of the River Doe and its tributaries is captured and fed into a branch tunnel, where it can either be used by the turbine directly, or can be fed into Loch Cluanie for later use. A dam

3096-625: A translation of the New Testament. In 1798, four tracts in Gaelic were published by the Society for Propagating the Gospel at Home, with 5,000 copies of each printed. Other publications followed, with a full Gaelic Bible in 1801. The influential and effective Gaelic Schools Society was founded in 1811. Their purpose was to teach Gaels to read the Bible in their own language. In the first quarter of

3225-412: A typical concrete sets in about 6 hours and develops a compressive strength of 8 MPa in 24 hours. The strength rises to 15 MPa at 3 days, 23 MPa at 1 week, 35 MPa at 4 weeks, and 41 MPa at 3 months. In principle, the strength continues to rise slowly as long as water is available for continued hydration, but concrete is usually allowed to dry out after

3354-440: A very low (C 3 A) composition which accounts for its high sulphate resistance. The maximum content of (C 3 A) allowed is 5% for type V portland cement. Another limitation is that the (C 4 AF) + 2(C 3 A) composition cannot exceed 20%. This type is used in concrete to be exposed to alkali soil and ground water sulphates which react with (C 3 A) causing disruptive expansion. It is unavailable in many places, although its use

3483-543: Is immediately dangerous to life and health . Portland cement manufacture can cause environmental impacts at all stages of the process. These include emissions of airborne pollution in the form of dust; gases; noise and vibration when operating machinery and during blasting in quarries; consumption of large quantities of fuel during manufacture; release of CO 2 from the raw materials during manufacture, and damage to countryside from quarrying. Equipment to reduce dust emissions during quarrying and manufacture of cement

3612-581: Is 748 feet (228 m) above Ordnance datum (AOD), and it is relatively shallow. The Cluanie dam is also a mass gravity dam, 2,215 feet (675 m) long and 133 feet (41 m) high. Compensation water for the River Moriston flows through a small power station located at the base of the dam. Both the Loyne dam and the Cluanie dam were built using ground blast furnace slag, which replaced 70 percent of

3741-490: Is a significant step forward for the recognition of Gaelic both at home and abroad and I look forward to addressing the council in Gaelic very soon. Seeing Gaelic spoken in such a forum raises the profile of the language as we drive forward our commitment to creating a new generation of Gaelic speakers in Scotland." Bilingual road signs, street names, business and advertisement signage (in both Gaelic and English) are gradually being introduced throughout Gaelic-speaking regions in

3870-404: Is added to the clinker, and the mixture is finely ground to form the finished cement powder. This is achieved in a cement mill . The grinding process is controlled to obtain a powder with a broad particle size range , in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the ' specific surface area ', which

3999-409: Is also used in mortars (with sand and water only), for plasters and screeds , and in grouts (cement/water mixes squeezed into gaps to consolidate foundations, road-beds, etc.). When water is mixed with portland cement, the product sets in a few hours and hardens over a period of weeks. These processes can vary widely, depending upon the mix used and the conditions of curing of the product, but

4128-457: Is common in the western United States and Canada. As with type IV, type V portland cement has mainly been supplanted by the use of ordinary cement with added ground granulated blast furnace slag or tertiary blended cements containing slag and fly ash. Types Ia , IIa , and IIIa have the same composition as types I, II, and III. The only difference is that in Ia, IIa, and IIIa, an air-entraining agent

4257-492: Is controlled remotely from Glenmoriston power station. In addition, a system of aqueducts collects water from streams flowing into the Moriston downstream of Dundreggan Reservoir, and feeds some of their flow into Bhlaraidh Reservoir. Power generated by the stations is fed to Auchterewe, near Fort William, by overhead transmission lines, where there is a switching station and control centre. From Auchterewe, 132 kV lines distribute

4386-429: Is delivered to end users either in bags, or as bulk powder blown from a pressure vehicle into the customer's silo. In industrial countries, 80% or more of cement is delivered in bulk. Cement sets when mixed with water by way of a complex series of chemical reactions still only partly understood. The different constituents slowly crystallise, and the interlocking of their crystals gives cement its strength. Carbon dioxide

4515-462: Is extensive forest on both banks of the river, which gradually widens as it becomes part of Dundreggan Reservoir. A dam impounds the water at its eastern end, and a hydro-electric power station is located on the south bank close to the dam. The river narrows again, as it is fed with compensation water from the dam, and is joined by Allt Bhlaraidh, flowing southwards from three lochs and a reservoir, all of which are dammed. The river finally turns towards

4644-411: Is generally known for its low heat of hydration. Its typical compound composition is: 28% (C 3 S), 49% (C 2 S), 4% (C 3 A), 12% (C 4 AF), 1.8% MgO, 1.9% (SO 3 ), 0.9% ignition loss, and 0.8% free CaO. The percentages of (C 2 S) and (C 4 AF) are relatively high and (C 3 S) and (C 3 A) are relatively low. A limitation on this type is that the maximum percentage of (C 3 A) is seven, and

4773-516: Is generally not stocked by manufacturers, but some might consider a large special order. This type of cement has not been made for many years, because portland-pozzolan cements and ground granulated blast furnace slag addition offer a cheaper and more reliable alternative. Type V is used where sulphate resistance is important. Its typical compound composition is: 38% (C 3 S), 43% (C 2 S), 4% (C 3 A), 9% (C 4 AF), 1.9% MgO, 1.8% (SO 3 ), 0.9% ignition loss, and 0.8% free CaO. This cement has

4902-418: Is ground into the mix. The air-entrainment must meet the minimum and maximum optional specification found in the ASTM manual. These types are only available in the eastern United States and Canada, only on a limited basis. They are a poor approach to air-entrainment which improves resistance to freezing under low temperatures. Types II(MH) and II(MH)a have a similar composition as types II and IIa, but with

5031-452: Is heated to high temperature. The key chemical reaction distinguishing portland cement from other hydraulic limes occurs at these high temperatures (>1,300 °C (2,370 °F)) as belite (Ca 2 SiO 4 ) combines with calcium oxide (CaO) to form alite (Ca 3 SiO 5 ). Portland cement clinker is made by heating, in a cement kiln , a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then

5160-411: Is impounded by a dam, which is 1,800 feet (550 m) long and 72 feet (22 m) high. Most of the water released from the loch passes along a tunnel and into Loch Cluanie. A small amount of electricity is generated by an induction generator in the pipeline. The dam is a mass gravity dam, and construction was completed in 1956. The loch covers an area of 2.43 square miles (6.3 km), the surface level

5289-478: Is in contact with soils and ground water, especially in the western United States due to the high sulphur content of the soils. Because of similar price to that of type I, type II is much used as a general purpose cement, and the majority of portland cement sold in North America meets this specification. Note: Cement meeting (among others) the specifications for types I and II has become commonly available on

5418-537: Is maintained by releasing compensation water from the loch. The A887 road from Kyle of Lochalsh to Loch Ness closely follows the course of the river for much of its length, and is on the north bank at this point. A small river, the Allt nam Peathrain, flows southwards to pass under the road and join the channel on its left bank. At Bun Loyne, a bridge carries the A87 road over the river, as it heads southwards to Glen Garry and

5547-425: Is necessary to limit the amount of tricalcium aluminate (3 CaO·Al 2 O 3 ) formed. The major raw material for the clinker-making is usually limestone ( CaCO 3 ) mixed with a second material containing clay as source of alumino-silicate. Normally, an impure limestone which contains clay or SiO 2 is used. The CaCO 3 content of these limestones can be as low as 80%. Secondary raw materials (materials in

5676-411: Is no evidence that Gaelic was ever widely spoken. Many historians mark the reign of King Malcolm Canmore ( Malcolm III ) between 1058 and 1093 as the beginning of Gaelic's eclipse in Scotland. His wife Margaret of Wessex spoke no Gaelic, gave her children Anglo-Saxon rather than Gaelic names, and brought many English bishops, priests, and monastics to Scotland. When Malcolm and Margaret died in 1093,

5805-473: Is not to be in contact with soils or ground water. The typical compound compositions of this type are: 55% (C 3 S), 19% (C 2 S), 10% (C 3 A), 7% (C 4 AF), 2.8% MgO, 2.9% (SO 3 ), 1.0% ignition loss , and 1.0% free CaO (utilizing cement chemist notation ). A limitation on the composition is that the (C 3 A) shall not exceed 15%. Type II provides moderate sulphate resistance, and gives off less heat during hydration. This type of cement costs about

5934-423: Is slowly absorbed to convert the portlandite (Ca(OH) 2 ) into insoluble calcium carbonate . After the initial setting, immersion in warm water will speed up setting. Gypsum is added as an inhibitor to prevent flash (or quick) setting. The most common use for portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate ( gravel and sand ), cement, and water. As

6063-410: Is stable or increasing. While the hydro-electric schemes were being constructed in both Glen Moriston and Glen Garry, the roads running through the glens were upgraded. The main route from Invergarry to Kyle of Lochalsh formerly ran along Glen Garry to the hamlet of Tomdoun , turned northwards to cross Loch Loyne at a narrow point near the centre of the present loch, and continued to the north-west to

6192-406: Is that the six-month strength of type III is the same or slightly less than that of types I and II. Therefore, the long-term strength is sacrificed. It is usually used for precast concrete manufacture, where high one-day strength allows fast turnover of molds. It may also be used in emergency construction and repairs, and construction of machine bases and gate installations. Type IV portland cement

6321-476: Is the most common type of cement in general use around the world as a basic ingredient of concrete , mortar , stucco , and non-specialty grout . It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin , and is usually made from limestone . It is a fine powder , produced by heating limestone and clay minerals in a kiln to form clinker , and then grinding

6450-522: Is the total particle surface area of a unit mass of cement. The rate of initial reaction (up to 24 hours) of the cement on addition of water is directly proportional to the specific surface area. Typical values are 320–380 m ·kg for general purpose cements, and 450–650 m ·kg for 'rapid hardening' cements. The cement is conveyed by belt or powder pump to a silo for storage. Cement plants normally have sufficient silo space for one to 20 weeks of production, depending upon local demand cycles. The cement

6579-477: Is thought to date from the mid-18th century. A replacement bridge was built in 1933, slightly further downstream. It consists of a single 90-foot (27 m) concrete span with a small flood arch, and was designed by Mears and Carcus-Wilson. Below the newer bridge is a nine-sided gazebo, perched on a rocky outcrop overlooking the river. It dates from the early 19th century. Shortly afterwards, the river discharges into Loch Ness. The Garry-Moriston hydro-electric scheme

6708-518: The 2011 census of Scotland , 57,375 people (1.1% of the Scottish population aged over three years old) reported being able to speak Gaelic, 1,275 fewer than in 2001. The highest percentages of Gaelic speakers were in the Outer Hebrides . Nevertheless, there is a language revival , and the number of speakers of the language under age 20 did not decrease between the 2001 and 2011 censuses. In

6837-538: The 2021 census , 2,170 Canadian residents claimed knowledge of Scottish Gaelic, a decline from 3,980 speakers in the 2016 census . There exists a particular concentration of speakers in Nova Scotia , with historic communities in other parts of Canada having largely disappeared. Scottish Gaelic is classed as an indigenous language under the European Charter for Regional or Minority Languages , which

6966-468: The 2022 census of Scotland , it was found that 2.5% of the Scottish population had some skills in Gaelic, or 130,161 persons. Of these, 69,701 people reported speaking the language, with a further 46,404 people reporting that they understood the language, but did not speak, read, or write in it. Outside of Scotland, a dialect known as Canadian Gaelic has been spoken in Canada since the 18th century. In

7095-476: The German Standard , issued in 1909). Clinkers make up more than 90% of the cement, along with a limited amount of calcium sulphate (CaSO 4 , which controls the set time), and up to 5% minor constituents (fillers) as allowed by various standards. Clinkers are nodules (diameters, 0.2–1.0 inch [5.1–25.4 millimetres]) of a sintered material that is produced when a raw mixture of predetermined composition

7224-471: The London sewer project . This became a specification for portland cement. The next development in the manufacture of portland cement was the introduction of the rotary kiln , patented by Frederick Ransome in 1885 (U.K.) and 1886 (U.S.); which allowed a stronger, more homogeneous mixture and a continuous manufacturing process. The Hoffmann "endless" kiln which was said to give "perfect control over combustion"

7353-553: The Occupational Safety and Health Administration (OSHA) has set the legal limit ( permissible exposure limit ) for portland cement exposure in the workplace as 50 mppcf (million particles per cubic foot) over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 10 mg/m total exposure and 5 mg/m respiratory exposure over an 8-hour workday. At levels of 5000 mg/m , portland cement

7482-492: The Outer Hebrides , accommodation ethics exist amongst native or local Gaelic speakers when engaging with new learners or non-locals. Accommodation ethics, or ethics of accommodation, is a social practice where local or native speakers of Gaelic shift to speaking English when in the presence of non-Gaelic speakers out of a sense of courtesy or politeness. This accommodation ethic persists even in situations where new learners attempt to speak Gaelic with native speakers. This creates

7611-534: The River Garry . Below the bridge, the River Loyne joins on the right bank. This is largely compensation water released from the dam at the eastern end of Loch Loyne . The A887 road crosses to the south bank at Ceannacroc Bridge. The road formerly crossed the old bridge, constructed by Thomas Telford in 1808-1811, and located a little further downstream. It consists of a main span of 50 feet (15 m) for

7740-688: The Scottish Lowlands . Between the 2001 and 2011 censuses, the number of Gaelic speakers rose in nineteen of the country's 32 council areas. The largest absolute gains were in Aberdeenshire (+526), North Lanarkshire (+305), the Aberdeen City council area (+216), and East Ayrshire (+208). The largest relative gains were in Aberdeenshire (+0.19%), East Ayrshire (+0.18%), Moray (+0.16%), and Orkney (+0.13%). In 2018,

7998-786: The significant increase in pupils in Gaelic-medium education since that time is unknown. Gaelic Medium Education is one of the primary ways that the Scottish Government is addressing Gaelic language shift. Along with the Bòrd na Gàidhlig policies, preschool and daycare environments are also being used to create more opportunities for intergenerational language transmission in the Outer Hebrides.  However, revitalization efforts are not unified within Scotland or Nova Scotia, Canada. One can attend Sabhal Mòr Ostaig ,

8127-601: The 19th century, the SSPCK (despite their anti-Gaelic attitude in prior years) and the British and Foreign Bible Society distributed 60,000 Gaelic Bibles and 80,000 New Testaments. It is estimated that this overall schooling and publishing effort gave about 300,000 people in the Highlands some basic literacy. Very few European languages have made the transition to a modern literary language without an early modern translation of

8256-404: The 2011 Census. The 2011 total population figure comes from table KS101SC. The numbers of Gaelic speakers relate to the numbers aged 3 and over, and the percentages are calculated using those and the number of the total population aged 3 and over. Across the whole of Scotland, the 2011 census showed that 25,000 people (0.49% of the population) used Gaelic at home. Of these, 63.3% said that they had

An alternative view has been voiced by archaeologist Ewan Campbell , who has argued that the putative migration or takeover is not reflected in archaeological or placename data (as pointed out earlier by Leslie Alcock ). Campbell has also questioned

8514-569: The Bible; the lack of a well known translation may have contributed to the decline of Scottish Gaelic. Counterintuitively, access to schooling in Gaelic increased knowledge of English. In 1829, the Gaelic Schools Society reported that parents were unconcerned about their children learning Gaelic, but were anxious to have them taught English. The SSPCK also found Highlanders to have significant prejudice against Gaelic. T. M. Devine attributes this to an association between English and

8643-669: The Cluanie Inn, at the western end of the present Loch Cluanie. When the level of Loch Loyne was raised, the crossing point was submerged, and a new A87 road was constructed, turning northwards from the old road near the eastern end of Loch Garry, running along part of the shore of Loch Loyne, and crossing over the River Loyne beyond the eastern end of the loch, to join the A887 Invermoriston to Kyle of Lochalsh road at Bun Loyne. An original bridge became visible in 2012 due to low levels of rainfall, and corresponding low levels in

8772-594: The EU's institutions. The Scottish government had to pay for the translation from Gaelic to other European languages . The deal was received positively in Scotland; Secretary of State for Scotland Jim Murphy said the move was a strong sign of the UK government's support for Gaelic. He said; "Allowing Gaelic speakers to communicate with European institutions in their mother tongue is a progressive step forward and one which should be welcomed". Culture Minister Mike Russell said; "this

8901-538: The Forth–Clyde line and along the northeastern coastal plain as far north as Moray. Norman French completely displaced Gaelic at court. The establishment of royal burghs throughout the same area, particularly under David I , attracted large numbers of foreigners speaking Old English. This was the beginning of Gaelic's status as a predominantly rural language in Scotland. Clan chiefs in the northern and western parts of Scotland continued to support Gaelic bards who remained

9030-684: The Gaelic Act falls so far short of the status accorded to Welsh that one would be foolish or naïve to believe that any substantial change will occur in the fortunes of the language as a result of Bòrd na Gàidhlig 's efforts. On 10 December 2008, to celebrate the 60th anniversary of the Universal Declaration of Human Rights , the Scottish Human Rights Commission had the UDHR translated into Gaelic for

9159-762: The Gaelic aristocracy rejected their anglicised sons and instead backed Malcolm's brother Domnall Bán ( Donald III ). Donald had spent 17 years in Gaelic Ireland and his power base was in the thoroughly Gaelic west of Scotland. He was the last Scottish monarch to be buried on Iona , the traditional burial place of the Gaelic Kings of Dàl Riada and the Kingdom of Alba. However, during the reigns of Malcolm Canmore's sons, Edgar, Alexander I and David I (their successive reigns lasting 1097–1153), Anglo-Norman names and practices spread throughout Scotland south of

9288-619: The Highland and Island region. In 1616, the Privy Council proclaimed that schools teaching in English should be established. Gaelic was seen, at this time, as one of the causes of the instability of the region. It was also associated with Catholicism. The Society in Scotland for the Propagation of Christian Knowledge (SSPCK) was founded in 1709. They met in 1716, immediately after the failed Jacobite rising of 1715 , to consider

9417-416: The Highlands and Islands, including Argyll. In many cases, this has simply meant re-adopting the traditional spelling of a name (such as Ràtagan or Loch Ailleart rather than the anglicised forms Ratagan or Lochailort respectively). Some monolingual Gaelic road signs, particularly direction signs, are used on the Outer Hebrides , where a majority of the population can have a working knowledge of

9546-726: The Inner Hebridean dialects of Tiree and Islay, and even a few native speakers from Western Highland areas including Wester Ross , northwest Sutherland , Lochaber and Argyll . Dialects on both sides of the Straits of Moyle (the North Channel ) linking Scottish Gaelic with Irish are now extinct, though native speakers were still to be found on the Mull of Kintyre , on Rathlin and in North East Ireland as late as

9675-631: The Irish language ( Gaeilge ) and the Manx language ( Gaelg ). Scottish Gaelic is distinct from Scots , the Middle English -derived language which had come to be spoken in most of the Lowlands of Scotland by the early modern era . Prior to the 15th century, this language was known as Inglis ("English") by its own speakers, with Gaelic being called Scottis ("Scottish"). Beginning in

9804-610: The UK Government as Welsh . With the advent of devolution , however, Scottish matters have begun to receive greater attention, and it achieved a degree of official recognition when the Gaelic Language (Scotland) Act was enacted by the Scottish Parliament on 21 April 2005. The key provisions of the Act are: After its creation, Bòrd na Gàidhlig required a Gaelic Language Plan from the Scottish Government. This plan

9933-826: The Western Isles (−1,745), Argyll & Bute (−694), and Highland (−634). The drop in Stornoway , the largest parish in the Western Isles by population, was especially acute, from 57.5% of the population in 1991 to 43.4% in 2011. The only parish outside the Western Isles over 40% Gaelic-speaking is Kilmuir in Northern Skye at 46%. The islands in the Inner Hebrides with significant percentages of Gaelic speakers are Tiree (38.3%), Raasay (30.4%), Skye (29.4%), Lismore (26.9%), Colonsay (20.2%), and Islay (19.0%). Today, no civil parish in Scotland has

10062-589: The Western Isles. The Scottish Qualifications Authority offer two streams of Gaelic examination across all levels of the syllabus: Gaelic for learners (equivalent to the modern foreign languages syllabus) and Gaelic for native speakers (equivalent to the English syllabus). An Comunn Gàidhealach performs assessment of spoken Gaelic, resulting in the issue of a Bronze Card, Silver Card or Gold Card. Syllabus details are available on An Comunn's website. These are not widely recognised as qualifications, but are required for those taking part in certain competitions at

10191-522: The age and reliability of the medieval historical sources speaking of a conquest. Instead, he has inferred that Argyll formed part of a common Q-Celtic -speaking area with Ireland, connected rather than divided by the sea, since the Iron Age. These arguments have been opposed by some scholars defending the early dating of the traditional accounts and arguing for other interpretations of the archaeological evidence. Regardless of how it came to be spoken in

10320-463: The annual mods . In October 2009, a new agreement allowed Scottish Gaelic to be formally used between Scottish Government ministers and European Union officials. The deal was signed by Britain's representative to the EU, Sir Kim Darroch , and the Scottish government . This did not give Scottish Gaelic official status in the EU but gave it the right to be a means of formal communications in

10449-603: The bill be strengthened, a revised bill was published; the main alteration was that the guidance of the Bòrd is now statutory (rather than advisory). In the committee stages in the Scottish Parliament, there was much debate over whether Gaelic should be given 'equal validity' with English. Due to executive concerns about resourcing implications if this wording was used, the Education Committee settled on

10578-459: The cement which would otherwise have been used, reducing the amount of Portland cement used by 40,000 long tons (41,000 t). The project was the first time that this technique had been used in Britain. Loch Cluanie is much deeper than Loch Loyne. It covers an area of 4.04 square miles (1,046 ha) and its surface level is 705 feet (215 m) AOD, which is 96 feet (29 m) higher than it

10707-625: The census of pupils in Scotland showed 520 students in publicly funded schools had Gaelic as the main language at home, an increase of 5% from 497 in 2014. During the same period, Gaelic medium education in Scotland has grown, with 4,343 pupils (6.3 per 1000) being educated in a Gaelic-immersion environment in 2018, up from 3,583 pupils (5.3 per 1000) in 2014. Data collected in 2007–2008 indicated that even among pupils enrolled in Gaelic medium schools, 81% of primary students and 74% of secondary students report using English more often than Gaelic when speaking with their mothers at home. The effect on this of

10836-568: The cities and professors of Celtic from universities who sought to preserve the language. The Education (Scotland) Act 1872 provided universal education in Scotland, but completely ignored Gaelic in its plans. The mechanism for supporting Gaelic through the Education Codes issued by the Scottish Education Department were steadily used to overcome this omission, with many concessions in place by 1918. However,

10965-472: The clinker with the addition of several percent (often around 5%) gypsum . Several types of portland cement are available. The most common, historically called ordinary portland cement (OPC), is grey, but white portland cement is also available. Its name is derived from its resemblance to Portland stone which is quarried on the Isle of Portland in Dorset , England. It was named by Joseph Aspdin who obtained

11094-450: The concept of 'equal respect'. It is not clear what the legal force of this wording is. The Act was passed by the Scottish Parliament unanimously, with support from all sectors of the Scottish political spectrum, on 21 April 2005. Under the provisions of the Act, it will ultimately fall to BnG to secure the status of the Gaelic language as an official language of Scotland. Some commentators, such as Éamonn Ó Gribín (2006) argue that

11223-468: The construction of a lighthouse, now known as Smeaton's Tower . In the late 18th century, Roman cement was developed and patented in 1796 by James Parker . Roman cement quickly became popular, but was largely replaced by portland cement in the 1850s. In 1811, James Frost produced a cement he called British cement. James Frost is reported to have erected a manufactory for making of an artificial cement in 1826. In 1811 Edgar Dobbs of Southwark patented

11352-499: The dialect of the Scottish Gaelic language, and also mixed use of English and Gaelic across the Highlands and Islands. Dialects of Lowland Gaelic have been defunct since the 18th century. Gaelic in the Eastern and Southern Scottish Highlands, although alive until the mid-20th century, is now largely defunct. Although modern Scottish Gaelic is dominated by the dialects of the Outer Hebrides and Isle of Skye, there remain some speakers of

11481-582: The entire region of modern-day Scotland was called Scotia in Latin, and Gaelic was the lingua Scotica . In southern Scotland , Gaelic was strong in Galloway , adjoining areas to the north and west, West Lothian , and parts of western Midlothian . It was spoken to a lesser degree in north Ayrshire , Renfrewshire , the Clyde Valley and eastern Dumfriesshire . In south-eastern Scotland, there

11610-668: The first portland cement was produced in the Coplay Cement Company Kilns under the direction of David O. Saylor in Coplay, Pennsylvania . By the early 20th century, American-made portland cement had displaced most of the imported portland cement. ASTM C150 defines portland cement as: hydraulic cement (cement that not only hardens by reacting with water but also forms a water-resistant product) produced by pulverizing clinkers which consist essentially of hydraulic calcium silicates, usually containing one or more of

11739-560: The first time. However, given there are no longer any monolingual Gaelic speakers, following an appeal in the court case of Taylor v Haughney (1982), involving the status of Gaelic in judicial proceedings, the High Court ruled against a general right to use Gaelic in court proceedings. While the goal of the Gaelic Language Act was to aid in revitalization efforts through government mandated official language status,

11868-581: The forms of calcium sulphate as an inter ground addition. The European Standard EN 197-1 uses the following definition: Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates , (3 CaO·SiO 2 , and 2 CaO·SiO 2 ) , the remainder consisting of aluminium- and iron-containing clinker phases and other compounds. The ratio of CaO to SiO 2 shall not be less than 2.0. The magnesium oxide content ( MgO ) shall not exceed 5.0% by mass. (The last two requirements were already set out in

11997-426: The general purpose clinker is usually used, ground to a specific surface area typically 50–80% higher. The gypsum level may also be increased a small amount. This gives the concrete using this type of cement a three-day compressive strength equal to the seven-day compressive strength of types I and II. Its seven-day compressive strength is almost equal to 28-day compressive strengths of types I and II. The only downside

12126-479: The initiatives must come from within Gaelic speaking communities, be led by Gaelic speakers, and be designed to serve and increase fluency within the vernacular communities as the first and most viable resistance to total language shift from Gaelic to English. Currently, language policies are focused on creating new language speakers through education, instead of focused on how to strengthen intergenerational transmission within existing Gaelic speaking communities. In

12255-502: The language. Compared with the 2001 Census, there has been a diminution of about 1300 people. This is the smallest drop between censuses since the Gaelic-language question was first asked in 1881. The Scottish government's language minister and Bòrd na Gàidhlig took this as evidence that Gaelic's long decline has slowed. The main stronghold of the language continues to be the Outer Hebrides ( Na h-Eileanan Siar ), where

12384-475: The language. These omit the English translation entirely. Bilingual railway station signs are now more frequent than they used to be. Practically all the stations in the Highland area use both English and Gaelic, and the use of bilingual station signs has become more frequent in the Lowlands of Scotland, including areas where Gaelic has not been spoken for a long time. Portland cement Portland cement

12513-532: The late 15th century, it became increasingly common for such speakers to refer to Scottish Gaelic as Erse ("Irish") and the Lowland vernacular as Scottis . Today, Scottish Gaelic is recognised as a separate language from Irish, so the word Erse in reference to Scottish Gaelic is no longer used. Based on medieval traditional accounts and the apparent evidence from linguistic geography, Gaelic has been commonly believed to have been brought to Scotland, in

12642-450: The left bank at Torgoyle Bridge. A bridge was constructed here in 1811 by Telford, but in 1818 was destroyed by a flood. A temporary wooden bridge was put in place to maintain the route, and the present three-arched structure was completed in 1823, to the design of Joseph Mitchell, who was Telford's principal inspector. The outside two arches span 48 feet (15 m) while the centre one, which is wider and higher, spans 55 feet (17 m). The

12771-584: The loch. [REDACTED] Media related to River Moriston at Wikimedia Commons Scottish Gaelic language Scottish Gaelic ( / ˈ ɡ æ l ɪ k / , GAL -ik ; endonym : Gàidhlig [ˈkaːlɪkʲ] ), also known as Scots Gaelic or simply Gaelic , is a Goidelic language (in the Celtic branch of the Indo-European language family ) native to the Gaels of Scotland . As

12900-417: The maximum percentage of (C 3 S) is thirty-five. This causes the heat given off by the hydration reaction to develop at a slower rate. Consequently, the strength of the concrete develops slowly. After one or two years the strength is higher than the other types after full curing. This cement is used for very large concrete structures, such as dams, which have a low surface to volume ratio. This type of cement

13029-459: The members of Highland school boards tended to have anti-Gaelic attitudes and served as an obstacle to Gaelic education in the late 19th and early 20th century. Loss of life due to World War I and the 1919 sinking of the HMY Iolaire , combined with emigration, resulted in the 1910s seeing unprecedented damage to the use of Scottish Gaelic, with a 46% fall in monolingual speakers and

13158-734: The mid-20th century. Records of their speech show that Irish and Scottish Gaelic existed in a dialect chain with no clear language boundary. Some features of moribund dialects have been preserved in Nova Scotia, including the pronunciation of the broad or velarised l ( l̪ˠ ) as [w] , as in the Lochaber dialect. The Endangered Languages Project lists Gaelic's status as "threatened", with "20,000 to 30,000 active users". UNESCO classifies Gaelic as " definitely endangered ". The 1755–2001 figures are census data quoted by MacAulay. The 2011 Gaelic speakers figures come from table KS206SC of

13287-532: The modern era. Some of this was driven by policy decisions by government or other organisations, while some originated from social changes. In the last quarter of the 20th century, efforts began to encourage use of the language. The Statutes of Iona , enacted by James VI in 1609, was one piece of legislation that addressed, among other things, the Gaelic language. It required the heirs of clan chiefs to be educated in lowland, Protestant, English-speaking schools. James VI took several such measures to impose his rule on

13416-419: The mouth of the River Moriston through a tailrace tunnel which is 20 feet (6.1 m) in diameter and around 4 miles (6.4 km) long. The level of the reservoir is controlled by automatic sector gates. Compensation water for the river is discharged through another small power station, built into the dam. When the dam was constructed, a Borland type fish pass was included, to allow fish to move upstream beyond

13545-695: The official language of government and law. Scotland's emergent nationalism in the era following the conclusion of the Wars of Scottish Independence was organized using Scots as well. For example, the nation's great patriotic literature including John Barbour's The Brus (1375) and Blind Harry's The Wallace (before 1488) was written in Scots, not Gaelic. By the end of the 15th century, English/Scots speakers referred to Gaelic instead as 'Yrisch' or 'Erse', i.e. Irish and their own language as 'Scottis'. A steady shift away from Scottish Gaelic continued into and through

13674-459: The outcome of the act is distanced from the actual minority language communities. It helps to create visibility of the minority language in civil structures, but does not impact or address the lived experiences of the Gaelic speaker communities wherein the revitalization efforts may have a higher return of new Gaelic speakers. Efforts are being made to concentrate resources, language planning, and revitalization efforts towards vernacular communities in

13803-560: The overall proportion of speakers is 52.2%. Important pockets of the language also exist in the Highlands (5.4%) and in Argyll and Bute (4.0%) and Inverness (4.9%). The locality with the largest absolute number is Glasgow with 5,878 such persons, who make up over 10% of all of Scotland's Gaelic speakers. Gaelic continues to decline in its traditional heartland. Between 2001 and 2011, the absolute number of Gaelic speakers fell sharply in

13932-471: The power in several directions. Those over the Corrieyarrick Pass are very exposed, reaching a height of 2,507 feet (764 m) AOD, and high frequency pulses are injected into the lines to enable faults to be located. The construction of the hydro-electric stations has brought some benefits to the area, which are wider than just providing electricity to remote communities. The dam at Dundreggan

14061-466: The prosperity of employment: the Highland economy relied greatly on seasonal migrant workers travelling outside the Gàidhealtachd . In 1863, an observer sympathetic to Gaelic stated that "knowledge of English is indispensable to any poor islander who wishes to learn a trade or to earn his bread beyond the limits of his native Isle". Generally, rather than Gaelic speakers, it was Celtic societies in

14190-423: The raw mix other than limestone) depend on the purity of the limestone. Some of the materials used are clay , shale , sand , iron ore , bauxite , fly ash , and slag . When a cement kiln is fired by coal, the ash of the coal acts as a secondary raw material. To achieve the desired setting qualities in the finished product, a quantity (2–8%, but typically 5%) of calcium sulphate (usually gypsum or anhydrite )

14319-460: The reform and civilisation of the Highlands, which they sought to achieve by teaching English and the Protestant religion. Initially, their teaching was entirely in English, but soon the impracticality of educating Gaelic-speaking children in this way gave rise to a modest concession: in 1723, teachers were allowed to translate English words in the Bible into Gaelic to aid comprehension, but there

14448-587: The region, Gaelic in Scotland was mostly confined to Dál Riata until the eighth century, when it began expanding into Pictish areas north of the Firth of Forth and the Firth of Clyde. During the reign of Caustantín mac Áeda (Constantine II, 900–943), outsiders began to refer to the region as the kingdom of Alba rather than as the kingdom of the Picts. However, though the Pictish language did not disappear suddenly,

14577-529: The river and a flood arch of 36 feet (11 m). The river sweeps round in a large bend, where it is joined by the waters of the River Doe and its tributary the Allt Bhuruisgidh, both of which are dammed further upstream. The main channel continues in an east-north-easterly direction, past the hamlet of Tomchrasky on its northern bank. There is a hatchery on the right bank, and then the A887 crosses to

14706-416: The same as type I. Its typical compound composition is: 51% (C 3 S), 24% (C 2 S), 6% (C 3 A), 11% (C 4 AF), 2.9% MgO, 2.5% (SO 3 ), 0.8% ignition loss, and 1.0% free CaO. A limitation on the composition is that the (C 3 A) shall not exceed 8%, which reduces its vulnerability to sulphates. This type is for general construction exposed to moderate sulphate attack, and is meant for use when concrete

14835-518: The sinuses and lungs can also cause a chemical burn, as well as headaches, fatigue, and lung cancer. The production of comparatively low-alkalinity cements (pH<11) is an area of ongoing investigation. In Scandinavia , France, and the United Kingdom, the level of chromium(VI) , which is considered to be toxic and a major skin irritant, may not exceed 2 parts per million (ppm). In the US,

14964-469: The south-east as it approached Invermoriston , the main settlement on its course. The A82 road which runs along the bank of Loch Ness used to cross the river on a two-arched bridge, with another arch on the right bank of the river and a three-arched clapper bridge in the approach on the left bank. It is in line with Telford's road built for the Commission for Highland Roads and Bridges in 1808-1811, but

15093-505: The structure. A third power station on the River Moriston system was constructed in 1962. The Livishie station generates 15 MW, and a head of 850 feet (259 m) is provided by the Bhlaraidh Reservoir. This acts as a headpool, but its water is supplemented by supplies from Loch a Chrathaich, Loch Laith and Loch ma Stac, all of which have had their capacity increased by the construction of small dams. Transfer from these lochs

15222-406: The world market. Type III has relatively high early strength. Its typical compound composition is: 57% (C 3 S), 19% (C 2 S), 10% (C 3 A), 7% (C 4 AF), 3.0% MgO, 3.1% (SO 3 ), 0.9% ignition loss, and 1.3% free CaO. This cement is similar to type I, but ground finer. Some manufacturers make a separate clinker with higher C 3 S and/or C 3 A content, but this is increasingly rare, and

15351-399: Was accepted in 2008, and some of its main commitments were: identity (signs, corporate identity); communications (reception, telephone, mailings, public meetings, complaint procedures); publications (PR and media, websites); staffing (language learning, training, recruitment). Following a consultation period, in which the government received many submissions, the majority of which asked that

15480-483: Was built across the River Moriston some 9 miles (14 km) downstream of the Loch Cluanie dam in 1957, to form Dundreggan Reservoir. It is a mass gravity dam 460 feet (140 m) long by 59 feet (18 m) high, and creates a headpond for Glenmoriston power station which is 300 feet (91 m) below the ground, and is fed by a vertical shaft. Once the water has passed through the two 18 MW turbines, it flows into

15609-402: Was built at a location where there had previously been a waterfall, which made the migration of salmon up the river impossible. However, a Borland fish pass , which works in a similar way to a navigation lock , was constructed at the site, and unlike the neighbouring River Garry, where salmon stocks have suffered serious decline, salmon have established themselves on the river, and the population

15738-542: Was developed from natural cements made in Britain beginning in the middle of the 18th century. Its name is derived from its similarity to Portland stone , a type of building stone quarried on the Isle of Portland in Dorset, England. The development of modern portland cement (sometimes called ordinary or normal portland cement) began in 1756, when John Smeaton experimented with combinations of different limestones and additives, including trass and pozzolanas , intended for

15867-483: Was involved in cement making. William Aspdin made what could be called "meso-portland cement" (a mix of portland cement and hydraulic lime). Isaac Charles Johnson further refined the production of "meso-portland cement" (middle stage of development), and claimed to be the real father of portland cement. In 1859, John Grant of the Metropolitan Board of Works, set out requirements for cement to be used in

15996-491: Was long suppressed. The UK government has ratified the European Charter for Regional or Minority Languages in respect of Gaelic. Gaelic, along with Irish and Welsh, is designated under Part III of the Charter, which requires the UK Government to take a range of concrete measures in the fields of education, justice, public administration, broadcasting and culture. It has not received the same degree of official recognition from

16125-510: Was no further permitted use. Other less prominent schools worked in the Highlands at the same time, also teaching in English. This process of anglicisation paused when evangelical preachers arrived in the Highlands, convinced that people should be able to read religious texts in their own language. The first well known translation of the Bible into Scottish Gaelic was made in 1767, when James Stuart of Killin and Dugald Buchanan of Rannoch produced

16254-481: Was nothing like modern portland cement, but a first step in the development of modern portland cement, and has been called a "proto-portland cement". William Aspdin had left his father's company, to form his own cement manufactury. In the 1840s William Aspdin, apparently accidentally, produced calcium silicates which are a middle step in the development of portland cement. In 1848, William Aspdin further improved his cement. Then, in 1853, he moved to Germany, where he

16383-487: Was one of several constructed by the North of Scotland Hydro-Electric Board , a public body formed in 1943 to promote water power in the Highlands. They used profits from similar schemes in the southern Highlands to fund remote schemes such as this, in order to stimulate economic regeneration of the area. The catchment for the River Moriston, which includes Loch Loyne and Loch Cluanie, is 158 square miles (410 km). Loch Loyne

16512-399: Was prior to construction of the dam. From Loch Cluanie, water is fed to a power station at Ceannacroc through a tunnel and pressure shaft. The power station was built underground and was one of the first underground stations to be constructed in the country, when it was completed in 1956. This arrangement provides a head of 300 feet (90 m) and the station can generate 20 MW. There is also

16641-620: Was tested in 1860 and shown to produce a superior grade of cement. This cement was made at the Portland Cementfabrik Stern at Stettin , which was the first to use a Hoffmann kiln. The Association of German Cement Manufacturers issued a standard on portland cement in 1878. Portland cement had been imported into the United States from Germany and England , and in the 1870s and 1880s, it was being produced by Eagle Portland cement near Kalamazoo, Michigan. In 1875,
