120-656: Old State Library Building is a heritage-listed former library building at 159 William Street , Brisbane City , City of Brisbane , Queensland , Australia. It is also known as the former Queensland Museum . It was added to the Queensland Heritage Register on 21 October 1992. Originally constructed for the Queensland Museum opposite Queens Gardens , the building contained the State Library of Queensland from 1902 to 1988, when
240-420: A crankcase , crankshaft , piston rod , piston , piston ring , cylinder head and valves. This compressor uses two interleaving scrolls to compress the refrigerant. it consists of one fixed and one orbiting scrolls. This type of compressor is more efficient because it has 70 percent less moving parts than a reciprocating compressor. This compressor use two very closely meshing spiral rotors to compress
360-557: A mezzanine and air conditioning and the removal of the skylight , at a cost of over £ 227,000. The exterior brickwork may also have been rendered at this time. The William Street frontage remained largely intact, as one of the city's few surviving 1870s facades. The State Library of Queensland (including the John Oxley Library) moved to new premises in the Queensland Cultural Centre in 1988, and
480-502: A special library or academic library, for example. Libraries may also be community hubs, where programmes are made available and people engage in lifelong learning. Modern libraries extend their services beyond the physical walls of the building by providing material accessible by electronic means, including from home via the Internet. The services that libraries offer are variously described as library services, information services, or
600-501: A "wired thermostat," is a device that controls an air conditioner by switching heating or cooling on or off. It uses different sensors to measure temperatures and actuate control operations. Mechanical thermostats commonly use bimetallic strips , converting a temperature change into mechanical displacement, to actuate control of the air conditioner. Electronic thermostats, instead, use a thermistor or other semiconductor sensor, processing temperature change as electronic signals to control
720-534: A 1939 architecture graduate from the University of Texas at Austin , developed the first experimental "suburb" with inbuilt air conditioning in each house. 22 homes were developed on a flat, treeless track in northwest Austin, Texas , and the community was christened the 'Austin Air-Conditioned Village.' The residents were subjected to a year-long study of the effects of air conditioning led by
840-570: A 24-hour period. The value is equal to 12,000 BTU IT per hour, or 3,517 watts . Residential central air systems are usually from 1 to 5 tons (3.5 to 18 kW) in capacity. The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment . A similar standard
960-405: A cooling tower on its condenser side. An air source heat pump shares many components with an air conditioning system, but includes a reversing valve , which allows the unit to be used to heat as well as cool a space. Air conditioning equipment will reduce the absolute humidity of the air processed by the system if the surface of the evaporator coil is significantly cooler than the dew point of
1080-422: A defrosting cycle to be performed. The icing problem becomes much more severe with lower outdoor temperatures, so heat pumps are sometimes installed in tandem with a more conventional form of heating, such as an electrical heater, a natural gas , heating oil , or wood-burning fireplace or central heating , which is used instead of or in addition to the heat pump during harsher winter temperatures. In this case,
1200-778: A gap between the two walls to encourage air flow, were found in the ancient city of Hamoukar , in modern Syria . Ancient Egyptian buildings also used a wide variety of passive air-conditioning techniques. These became widespread from the Iberian Peninsula through North Africa, the Middle East, and Northern India. Passive techniques remained widespread until the 20th century when they fell out of fashion and were replaced by powered air conditioning. Using information from engineering studies of traditional buildings, passive techniques are being revived and modified for 21st-century architectural designs. Air conditioners allow
1320-676: A large library, the card catalogue often filled a large room. The emergence of desktop computers and the Internet , however, has led to the adoption of electronic catalogue databases (often referred to as "webcats" or as online public access catalogues , OPACs), which allow users to search the library's holdings from any location with Internet access. This style of catalogue maintenance is compatible with new types of libraries, such as digital libraries and distributed libraries , as well as older libraries that have been retrofitted . Large libraries may be scattered within multiple buildings across

#17327722844391440-538: A larger facility. Lamba (2019) reinforced this idea by observing that "today's libraries have become increasingly multi-disciplinary, collaborative and networked" and that applying Web 2.0 tools to libraries would "not only connect the users with their community and enhance communication but will also help the librarians to promote their library's activities, services, and products to target both their actual and potential users". Academic libraries are generally located on college and university campuses and primarily serve
1560-484: A love of books. One of the most popular programs offered in public libraries are summer reading programs for children, families, and adults. Another popular reading program for children is PAWS TO READ or similar programs where children can read to certified therapy dogs. Since animals are a calming influence and there is no judgment, children learn confidence and a love of reading. Many states have these types of programs: parents need simply ask their librarian to see if it
1680-793: A national library, putting less emphasis on the repository character. The first national libraries had their origins in the royal collections of the sovereign or some other supreme body of the state. Many national libraries cooperate within the National Libraries Section of the International Federation of Library Associations and Institutions (IFLA) to discuss their common tasks, define and promote common standards, and carry out projects helping them to fulfill their duties. The national libraries of Europe participate in The European Library which
1800-915: A parent organization and may serve only members of that organization. Examples of research libraries include the British Library , the Bodleian Library at Oxford University and the New York Public Library Main Branch on 42nd Street in Manhattan, State Public Scientific Technological Library of the Siberian Branch of the Russian Academy of Science . Digital libraries are libraries that house digital resources, such as text, photographs, and audio. These are curated by digital librarians. In
1920-456: A patent in 1851, but following the death of his main backer, he was not able to realize his invention. In 1851, James Harrison created the first mechanical ice-making machine in Geelong, Australia , and was granted a patent for an ether vapor-compression refrigeration system in 1855 that produced three tons of ice per day. In 1860, Harrison established a second ice company. He later entered
2040-684: A physical location, a virtual space, or both. A library's collection normally includes printed materials which may be borrowed, and usually also includes a reference section of publications which may only be utilized inside the premises. Resources such as commercial releases of films, television programmes, other video recordings, radio, music and audio recordings may be available in many formats. These include DVDs , Blu-rays , CDs , cassettes , or other applicable formats such as microform . They may also provide access to information, music or other content held on bibliographic databases . Libraries can vary widely in size and may be organised and maintained by
2160-436: A public body such as a government, an institution (such as a school or museum), a corporation, or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained experts in finding, selecting, circulating and organising information while interpreting information needs and navigating and analysing large amounts of information with a variety of resources. The area of study
2280-425: A quantity of gas from discharge to the suction side. The compressor will keep operating at the same speed, but due to the bypass, the refrigerant mass flow circulating with the system is reduced, and thus the cooling capacity. This naturally causes the compressor to run uselessly during the periods when the bypass is operating. The turn down capacity varies between 0 and 100%. Several compressors can be installed in
2400-504: A reference library, which does not lend its holdings, or a lending library, which does lend all or some of its holdings. Some extremely large or traditional research libraries are entirely reference in this sense, lending none of their materials; most academic research libraries, at least in the US and the UK, now lend books, but not periodicals or other materials. Many research libraries are attached to
2520-405: A remote control to the air conditioner. The output of the infrared LED (like that of any infrared remote) is invisible to the human eye because its wavelength is beyond the range of visible light (940 nm). This system is commonly used on mini-split air conditioners because it is simple and portable. Some window and ducted central air conditioners uses it as well. A wired controller, also called

Their work supplements that of the public schools. Services commonly provided by public libraries may include storytelling sessions for infants, toddlers, preschool children, or after-school programs, all with an intention of developing early literacy skills and
2760-460: A single or a few rooms of a building, without ducts and in a decentralized manner. Multi-zone or multi-split systems are a common application of ductless systems and allow up to eight rooms (zones or locations) to be conditioned independently from each other, each with its indoor unit and simultaneously from a single outdoor unit. The first mini-split system was sold in 1961 by Toshiba in Japan, and
2880-409: A small pediment above in the entablature. The large unfluted columns with lotus leaf capitals form a colonnade in front of the second and third storeys. Corbels rise through the entablature above each column . The top pediment is marked by stretches of balustrade . All the windows in this front facade are arched. The interior of the first section was substantially remodelled in 1964–1965, with

Depending on their construction they may be outdoors or indoors, on roofs ( rooftop units ), draw the air to be conditioned from inside or outside a building and be water or air-cooled. Often, outdoor units are air-cooled while indoor units are liquid-cooled using a cooling tower. medium (large capacity) This compressor consists of
3120-507: A staff member. Ways in which a library's content is displayed or accessed may have an impact on use. An antiquated or clumsy search system, or staff unwilling or not properly trained to engage their patrons, will limit a library's usefulness. In the public libraries of the United States, beginning in the 19th century, these problems drove the emergence of the library instruction movement, which advocated library user education. One of

Franklin concluded: "From this experiment, one may see the possibility of freezing a man to death on a warm summer's day." The 19th century included many developments in compression technology. In 1820, English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when

Once a user has located a resource within the catalogue, they must then use navigational guidance to retrieve the resource physically, a process that may be assisted through signage, maps, GPS systems, or RFID tagging. Finland has the highest number of registered book borrowers per capita in
3480-405: A university. Some items at reference libraries may be historical and even unique. Many lending libraries contain a "reference section", which holds books, such as dictionaries, which are common reference books, and are therefore not lent out. Such reference sections may be referred to as "reading rooms" or "study rooms", which may also include newspapers and periodicals. An example of a reading room
3600-424: A window frame or on a wall opening. The unit usually has an internal partition separating its indoor and outdoor sides, which contain the unit's condenser and evaporator, respectively. PTAC systems may be adapted to provide heating in cold weather, either directly by using an electric strip, gas , or other heaters, or by reversing the refrigerant flow to heat the interior and draw heat from the exterior air, converting
3720-487: Is a service of the Conference of European National Librarians (CENL). A public library provides services to the general public. If the library is part of a countywide library system, citizens with an active library card from around that county can use the library branches associated with the library system. A library can serve only their city, however, if they are not a member of the county public library system. Much of

3840-470: Is an attempt to make the library a more user-driven institution. Despite the importance ascribed to public libraries, their budgets are often cut by legislatures. In some cases, funding has dwindled so much that libraries have been forced to cut their hours and release employees. A reference library does not lend books and other items; instead, they can only be read at the library itself. Typically, such libraries are used for research purposes, for example at
3960-476: Is available at their local library. A national or state library serves as a national repository of information, and has the right of legal deposit , which is a legal requirement that publishers in the country need to deposit a copy of each publication with the library. Unlike a public library, a national library rarely allows citizens to borrow books. Often, their collections include numerous rare, valuable, or significant works. There are wider definitions of
4080-407: Is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often graphed or averaged against expected conditions. Air conditioner equipment power in the U.S. is often described in terms of " tons of refrigeration ", with each approximately equal to the cooling power of one short ton (2,000 pounds (910 kg) of ice melting in

A large university library may be considered a research library; and in North America, such libraries may belong to the Association of Research Libraries . In the United Kingdom, they may be members of Research Libraries UK (RLUK) . Particularly important collections in England may be designated by Arts Council England . A research library can be either
4440-497: Is not lent out. Travelling libraries, such as the early horseback libraries of eastern Kentucky and bookmobiles , are generally of the lending type. Modern libraries are often a mixture of both, containing a general collection for circulation, and a reference collection which is restricted to the library premises. Also, increasingly, digital collections enable broader access to material that may not circulate in print, and enables libraries to expand their collections even without building
4560-454: Is not practical to have available as hard copies. Furthermore, most libraries collaborate with other libraries in exchange of books. Specific course-related resources are usually provided by the library, such as copies of textbooks and article readings held on 'reserve' (meaning that they are loaned out only on a short-term basis, usually a matter of hours). Some academic libraries provide resources not usually associated with libraries, such as
4680-471: Is particularly attractive to younger library users. Digitization of books, particularly those that are out-of-print , in projects such as Google Books provides resources for library and other online users. Due to their holdings of valuable material, some libraries are important partners for search engines such as Google in realizing the potential of such projects and have received reciprocal benefits in cases where they have negotiated effectively. As

The FCU is then connected to the spaces to be cooled by ventilation ducts . Floor standing air conditioners are similar to this type of air conditioner but sit within spaces that need cooling. Large central cooling plants may use intermediate coolant such as chilled water pumped into air handlers or fan coil units near or in
4920-469: Is the European seasonal energy efficiency ratio (ESEER). Efficiency is strongly affected by the humidity of the air to be cooled. Dehumidifying the air before attempting to cool it can reduce subsequent cooling costs by as much as 90 percent. Thus, reducing dehumidifying costs can materially affect overall air conditioning costs. This type of controller uses an infrared LED to relay commands from

6000-866: The humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or by other methods, including passive cooling and ventilative cooling . Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC) . Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them both to heat and to cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration , range in size from small units used in vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps , which can be used for heating as well as cooling , are becoming increasingly common in cooler climates. Air conditioners can reduce mortality rates due to higher temperature. According to

The shift to digital libraries has greatly impacted the way people use physical libraries. Between 2002 and 2004, the average American academic library saw the overall number of transactions decline approximately 2.2%. The University of California Library System saw a 54% decline in circulation between 1991 and 2001 of 8,377,000 books to 3,832,000.

Academic libraries offer workshops and courses outside of formal, graded coursework, which are meant to provide students with the tools necessary to succeed in their programs. These workshops may include help with citations, effective search techniques, journal databases, and electronic citation software. These workshops provide students with skills that can help them achieve success in their academic careers (and often, in their future occupations), which they may not learn inside

In North America, Europe, and other parts of the world, academic libraries are becoming increasingly digitally oriented. The library provides a "gateway" for students and researchers to access various resources, both print/physical and digital. Academic institutions are subscribing to electronic journals databases, providing research and scholarly writing software, and usually provide computer workstations or computer labs for students to access journals, library search databases and portals, institutional electronic resources, Internet access, and course- or task-related software (i.e. word processing and spreadsheet software). Some academic libraries take on new roles, for instance, acting as an electronic repository for institutional scholarly research and academic knowledge, such as

Moreover, academic libraries are increasingly acting as publishers on their own on a not-for-profit basis, especially in the form of fully Open Access institutional publishers. Children's libraries are special collections of books intended for juvenile readers and usually kept in separate rooms of general public libraries. Some children's libraries have entire floors or wings dedicated to them in bigger libraries while smaller ones may have

The term library is based on the Latin word liber for 'book' or 'document', contained in Latin libraria 'collection of books' and librarium 'container for books'. Other modern languages use derivations from Ancient Greek βιβλιοθήκη ( bibliothēkē ), originally meaning 'book container', via Latin bibliotheca ( cf. French bibliothèque or German Bibliothek ). The history of libraries began with

Organizations or departments are often called by one of these names. Most libraries have materials arranged in a specified order according to a library classification system, so that items may be located quickly and collections browsed efficiently. Some libraries have additional galleries beyond
8640-400: The compression. There are several ways to modulate the cooling capacity in refrigeration or air conditioning and heating systems . The most common in air conditioning are: on-off cycling, hot gas bypass, use or not of liquid injection, manifold configurations of multiple compressors, mechanical modulation (also called digital), and inverter technology. Hot gas bypass involves injecting

A prominent example of this can be found in the Mongol massacre of the Nizaris at Alamut in 1256 and the torching of their library, "the fame of which", boasts the conqueror Juwayni, "had spread throughout the world". The libraries of Timbuktu were established in
9240-454: The early leaders was John Cotton Dana . The basic form of library instruction is sometimes known as information literacy . Libraries should inform their users of what materials are available in their collections and how to access that information. Before the computer age, this was accomplished by the card catalogue —a cabinet (or multiple cabinets) containing many drawers filled with index cards that identified books and other materials. In
9360-414: The educational institution. Academic libraries house current, reliable and relevant information resources spread through all the disciplines which serve to assuage the information requirements of students and faculty. In cases where not all books are housed some libraries have E-resources, where they subscribe for a given institution they are serving, in order to provide backups and additional information that
9480-565: The evaporator and the condenser into the same air path; the air first passes over the evaporator coil, where it is cooled and dehumidified before passing over the condenser coil, where it is warmed again before it is released back into the room. Free cooling can sometimes be selected when the external air is cooler than the internal air. Therefore, the compressor does not need to be used, resulting in high cooling efficiencies for these times. This may also be combined with seasonal thermal energy storage . Some air conditioning systems can reverse
9600-441: The first automobile manufacturer to offer an air conditioning unit in its cars in 1939. Innovations in the latter half of the 20th century allowed more ubiquitous air conditioner use. In 1945, Robert Sherman of Lynn, Massachusetts , invented a portable, in-window air conditioner that cooled, heated, humidified, dehumidified, and filtered the air. The first inverter air conditioners were released in 1980–1981. In 1954, Ned Cole,
9720-508: The first efforts to organize collections of documents. The first libraries consisted of archives of the earliest form of writing —the clay tablets in cuneiform script discovered in Sumer , some dating back to 2600 BC. Private or personal libraries made up of written books appeared in classical Greece in the 5th century BC. In the 6th century, at the very close of the Classical period ,
9840-636: The first wall-mounted mini-split air conditioner was sold in 1968 in Japan by Mitsubishi Electric , where small home sizes motivated their development. The Mitsubishi model was the first air conditioner with a cross-flow fan . In 1969, the first mini-split air conditioner was sold in the US. Multi-zone ductless systems were invented by Daikin in 1973, and variable refrigerant flow systems (which can be thought of as larger multi-split systems) were also invented by Daikin in 1982. Both were first sold in Japan. Variable refrigerant flow systems when compared with central plant cooling from an air handler , eliminate
9960-721: The fourteenth century and attracted scholars from all over the world. Libraries may provide physical or digital access to material, and may be a physical location, virtual space, or both. A library's collection can include books , periodicals , newspapers , manuscripts , films , maps , prints , documents , microform , CDs , cassettes , videotapes , DVDs , Blu-ray Discs , e-books , audiobooks , databases , table games , video games , and other formats. Libraries range widely in size, up to millions of items. Libraries often provide quiet spaces for private studying, common areas to facilitate group study and collaboration, and public facilities for access to their electronic resources and
10080-400: The gas. The gas enters at the suction side and moves through the threads as the screws rotate. The meshing rotors force the gas through the compressor, and the gas exits at the end of the screws. The working area is the inter-lobe volume between the male and female rotors. It is larger at the intake end, and decreases along the length of the rotors until the exhaust port. This change in volume is
10200-477: The great libraries of the Mediterranean world remained those of Constantinople and Alexandria . The Fatimids (r. 909–1171) also possessed many great libraries within their domains. The historian Ibn Abi Tayyi’ describes their palace library, which probably contained the largest collection of literature on earth at the time, as a " wonder of the world ". Throughout history, along with bloody massacres,
10320-408: The heat pump is in heating mode, the indoor evaporator coil switches roles and becomes the condenser coil, producing heat. The outdoor condenser unit also switches roles to serve as the evaporator and discharges cold air (colder than the ambient outdoor air). Most air source heat pumps become less efficient in outdoor temperatures lower than 4 °C or 40 °F. This is partly because ice forms on
10440-400: The heat pump is used efficiently during milder temperatures, and the system is switched to the conventional heat source when the outdoor temperature is lower. The coefficient of performance (COP) of an air conditioning system is a ratio of useful heating or cooling provided to the work required. Higher COPs equate to lower operating costs. The COP usually exceeds 1; however, the exact value
10560-465: The liquefied ammonia was allowed to evaporate. In 1842, Florida physician John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida . He hoped to eventually use his ice-making machine to regulate the temperature of buildings. He envisioned centralized air conditioning that could cool entire cities. Gorrie was granted
10680-416: The management of libraries through its Technical Committee 46 (TC 46), which is focused on "libraries, documentation and information centers, publishing, archives, records management, museum documentation, indexing and abstracting services, and information science". The following is a partial list of some of them: Some patrons may not know how to fully utilize library resources, or feel unease in approaching
10800-466: The materials located within a public library are available for borrowing. The library staff decides upon the number of items patrons are allowed to borrow, as well as the details of borrowing time allotted. Typically, libraries issue library cards to community members wishing to borrow books. Often visitors to a city are able to obtain a public library card. Many public libraries also serve as community organizations that provide free services and events to
10920-403: The most common type of individual room air conditioner: one designed to sit on a window ledge. The units went on sale in 1932 at US$ 10,000 to $ 50,000 (the equivalent of $ 200,000 to $ 1,100,000 in 2023.) A year later, the first air conditioning systems for cars were offered for sale. Chrysler Motors introduced the first practical semi-portable air conditioning unit in 1935, and Packard became
11040-718: The nation’s premier air conditioning companies, builders, and social scientists. In addition, researchers from UT’s Health Service and Psychology Department studied the effects on the "artificially cooled humans." One of the more amusing discoveries was that each family reported being troubled with scorpions, the leading theory being that scorpions sought cool, shady places. Other reported changes in lifestyle were that mothers baked more, families ate heavier foods, and they were more apt to choose hot drinks. Air conditioner adoption tends to increase above around $ 10,000 annual household income in warmer areas. Global GDP growth explains around 85% of increased air condition adoption by 2050, while
11160-885: The necessity for these services in doubt. Library scholars have acknowledged that libraries need to address the ways that they market their services if they are to compete with the Internet and mitigate the risk of losing users. This includes promoting the information literacy skills training considered vital across the library profession. Many US-based research librarians rely on the ACRL Framework for Information Literacy in order to guide students and faculty in research. However, marketing of services has to be adequately supported financially in order to be successful. This can be problematic for library services that are publicly funded and find it difficult to justify diverting tight funds to apparently peripheral areas such as branding and marketing. The privacy aspect of library usage in
11280-404: The need for large cool air ducts, air handlers, and chillers; instead cool refrigerant is transported through much smaller pipes to the indoor units in the spaces to be conditioned, thus allowing for less space above dropped ceilings and a lower structural impact, while also allowing for more individual and independent temperature control of spaces. The outdoor and indoor units can be spread across
11400-426: The needs of the library. Basic tasks in library management include planning acquisitions (which materials the library should acquire, by purchase or otherwise), classifying and preserving items (especially rare and fragile archival materials such as manuscripts), deaccessioning materials, patron borrowing, and developing and administering library computer systems and technology. More long-term issues include planning
11520-421: The number of books in libraries have steadily increased since their inception, the need for compact storage and access with adequate lighting has grown. The stack system involves keeping a library's collection of books in a space separate from the reading room. This arrangement arose in the 19th century. Book stacks quickly evolved into a fairly standard form in which the cast iron and steel frameworks supporting
11640-474: The original 1879 neoclassical structure and the 1959 modern extension. The original building was a three storeyed masonry structure with a sandstone facade . The facade is designed using classical elements , with a rusticated base and double-height columns rising from the piano nobile to support an entablature . The centre of the facade is marked by an aedicular containing an arched doorway, at ground level (the original entrance, now blocked in) and
11760-430: The outdoor unit's heat exchanger coil, which blocks air flow over the coil. To compensate for this, the heat pump system must temporarily switch back into the regular air conditioning mode to switch the outdoor evaporator coil back to the condenser coil, to heat up and defrost. Therefore, some heat pump systems will have electric resistance heating in the indoor air path that is activated only in this mode to compensate for
11880-461: The prominence of and reliance on the Internet has grown, library services have moved the emphasis from mainly providing print resources to providing more computers and more Internet access . Libraries face a number of challenges in adapting to new ways of information seeking that may stress convenience over quality, reducing the priority of information literacy skills. The potential decline in library usage, particularly reference services , puts
12000-516: The public ones, where "reference" materials are stored. These reference stacks may be open to selected members of the public while others may require patrons to submit a "stack request" – a request for an assistant to retrieve the material from the closed stacks: see List of closed stack libraries . Larger libraries are often divided into departments staffed by both paraprofessionals and professional librarians. Their department names and occupational designations may change depending on their location and
12120-511: The public, such as reading groups and toddler story time. For many communities, the library is a source of connection to a vast world, obtainable knowledge and understanding, and entertainment. According to a study by the Pennsylvania Library Association , public library services play a major role in fighting rising illiteracy rates among youths. Public libraries are protected and funded by the public they serve. As
12240-538: The rays of the sun, representing 'the dissemination of enlightenment to mankind - the function of a library as an instrument of enlightenment'. It was cast by the Non-Ferrous Foundry of Brisbane. The extensions were opened officially in August 1959 by Princess Alexandra . From 1964 to 1965 the original building underwent a major renovation, including the addition of a concrete frame structure, new floors,
12360-591: The refurbished building in April 1902. The name was changed to the State Library of Queensland in 1971. The John Oxley Library , established in 1926 as the principal centre for research material on Queensland history, was housed in the State Library building from 1931. As a major centennial project, the library building was extended in 1958–1959, at a cost of over £ 265,000. The additions, designed by government architects WG Thain, P Prystupa, U Stukoff, AJ Wheeler, D Davies and H de Jong, included an exhibition hall on
12480-498: The remaining 15% can be explained by climate change . As of 2016 an estimated 1.6 billion air conditioning units were used worldwide, with over half of them in China and USA , and a total cooling capacity of 11,675 gigawatts. The International Energy Agency predicted in 2018 that the number of air conditioning units would grow to around 4 billion units by 2050 and that the total cooling capacity would grow to around 23,000 GW, with
12600-463: The river, private work areas and shade from the sun. The Old State Library Building was listed on the Queensland Heritage Register on 21 October 1992 having satisfied the following criteria: [REDACTED] This Misplaced Pages article incorporates text from "The Queensland heritage register" published by the State of Queensland under CC-BY 3.0 AU licence (accessed on 7 July 2014, archived on 8 October 2014). The geo-coordinates were computed from
12720-404: The river. The choice of a classical style of architecture, modelled on 16th century Italian buildings and its central location close to the city's southern entrance, reflected the museum's importance in the scientific and cultural life of Brisbane. The building was completed and occupied early in 1879, but proved inadequate for museum purposes. In 1881 the area below was levelled and the basement
12840-411: The role of libraries in a nation's cultural heritage, and the role of government, church, or private sponsorship. Since the 1960s, issues of computerization and digitization have arisen. Many institutions make a distinction between a circulating or lending library , where materials are expected and intended to be loaned to patrons, institutions, or other libraries, and a reference library where material
12960-415: The spaces to be cooled which then duct or deliver cold air into the spaces to be conditioned, rather than ducting cold air directly to these spaces from the plant, which is not done due to the low density and heat capacity of air, which would require impractically large ducts. The chilled water is cooled by chillers in the plant, which uses a refrigeration cycle to cool water, often transferring its heat to
13080-623: The students and faculty of that and other academic institutions. Some academic libraries, especially those at public institutions, are accessible to members of the general public in whole or in part. Library services are sometimes extended to the general public at a fee; some academic libraries create such services in order to enhance literacy levels in their communities. Academic libraries are libraries that are hosted in post-secondary educational institutions, such as colleges and universities. Their main functions are to provide support in research, consultancy and resource linkage for students and faculty of
13200-427: The surrounding air. An air conditioner designed for an occupied space will typically achieve a 30% to 60% relative humidity in the occupied space. Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs. At the same time, the fan is slowed to reduce the evaporator temperature and condense more water. A dehumidifier uses the same refrigeration cycle but incorporates both
13320-412: The temperature and humidity, which helped maintain consistent paper dimensions and ink alignment at the printing plant. Later, together with six other employees, Carrier formed The Carrier Air Conditioning Company of America , a business that in 2020 employed 53,000 people and was valued at $ 18.6 billion. In 1906, Stuart W. Cramer of Charlotte, North Carolina , was exploring ways to add moisture to
13440-437: The temperature of an object past the freezing point of water. They experimented with the bulb of a mercury-in-glass thermometer as their object. They used a bellows to speed up the evaporation . They lowered the temperature of the thermometer bulb down to −14 °C (7 °F) while the ambient temperature was 18 °C (64 °F). Franklin noted that soon after they passed the freezing point of water 0 °C (32 °F),
13560-405: The temporary indoor air cooling, which would otherwise be uncomfortable in the winter. Newer models have improved cold-weather performance, with efficient heating capacity down to −14 °F (−26 °C). However, there is always a chance that the humidity that condenses on the heat exchanger of the outdoor unit could freeze, even in models that have improved cold-weather performance, requiring
13680-646: The term and incorporated it into the name of his company. Domestic air conditioning soon took off. In 1914, the first domestic air conditioning was installed in Minneapolis in the home of Charles Gilbert Gates . It is, however, possible that the considerable device (c. 2.1 m × 1.8 m × 6.1 m; 7 ft × 6 ft × 20 ft) was never used, as the house remained uninhabited (Gates had already died in October 1913.) In 1931, H.H. Schultz and J.Q. Sherman developed what would become
13800-515: The use of their employees in doing specialized research related to their work. Depending on the particular institution, special libraries may or may not be accessible to the general public or elements thereof. Air conditioning Air conditioning , often abbreviated as A/C (US) or air con (UK), is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling
13920-537: The water in a bucket or tray and stops when full. The air-to-air type re-evaporates the water, discharges it through the ducted hose, and can run continuously. Many but not all portable units draw indoor air and expel it outdoors through a single duct, negatively impacting their overall cooling efficiency. Many portable air conditioners come with heat as well as a dehumidification function. The packaged terminal air conditioner (PTAC), through-the-wall, and window air conditioners are similar. These units are installed on
14040-422: The western side and reading rooms on the river elevation. In 1958 national competitions were held for designs for a wall mural and sculpture to embellish the exterior of the new Centennial Hall. These were won by Victorian artist Lindsay Edward for his glass mosaic mural, and Brisbane sculptor Leonard George Shillam . Shillam's aluminium sculpture 'Enlightenment' showed three symbolic figures reaching towards
14160-412: The world. Over half of Finland's population are registered borrowers. In the US, public library users have borrowed on average roughly 15 books per user per year from 1856 to 1978. From 1978 to 2004, book circulation per user declined approximately 50%. The growth of audiovisuals circulation, estimated at 25% of total circulation in 2004, accounts for about half of this decline. A library may make use of
14280-520: Was extended. By 1884 the government was setting aside funds for a new museum building, but economic depression necessitated the museum remaining in the cramped William Street premises until removed to the former Exhibition Building at Gregory Terrace in 1899. A £ 1,900 contract was let in September 1900 for the conversion of the former museum building into premises for the free Public Library of Queensland , established in 1896. The library opened in
14400-489: Was needed, a method of moving shelves on tracks (compact shelving) was introduced to cut down on otherwise wasted aisle space. Library 2.0 , a term coined in 2005, is the library's response to the challenge of Google and an attempt to meet the changing needs of users by using Web 2.0 technology. Some of the aspects of Library 2.0 include, commenting, tagging, bookmarking, discussions, use of online social networks by libraries, plug-ins , and widgets . Inspired by Web 2.0, it
