Lawn Tennis Association
The Lawn Tennis Association (LTA) is the national governing body of tennis in Great Britain, the Channel Islands and the Isle of Man. Founded in 1888, the LTA promotes all levels of lawn tennis. It believes that tennis can provide "physical, social and mental rewards both on and off the court." The National Tennis Centre (NTC) in Roehampton, southwest London serves as its main training facility. The Princess of Wales has been an LTA patron since 2017. Its first president was seven-time Wimbledon champion William Renshaw. History The British Lawn Tennis Association formed in 1888, eleven years after the first Wimbledon championship. It was tasked with maintaining the new rules and standards of the emerging sport of tennis in the United Kingdom. In 1978, a government inquiry was carried out into the state of British tennis, which accused the LTA of complacency and a lack of action in developing the game. During the 1980s and 1990s, a number of initiatives were launched in an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Learning Through Art
Learning Through Art is an educational program of the Solomon R. Guggenheim Museum. LTA pairs practicing artists with participating public elementary school classrooms throughout the five boroughs of New York City. These resident artists spend one day a week for a period of 10 or 20 weeks working with classroom instructors to create and execute an art curriculum for the students that ties in with current Guggenheim exhibitions and supports the core curriculum learning inside of the classroom. Participating classrooms visit the Guggenheim multiple times throughout the duration of their program, and student artwork is shown in a culminating exhibition at the Guggenheim Museum in their annual ''A Year With Children'' showcase. History In 1970, in response to the cutting of art and music programs in New York City public schools, Natalie K. Lieberman started a program called Learning to Read Through the Arts. Later becoming a Guggenheim trustee, in 1994 the program was merged with the Gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a commissioned officer rank in the armed forces of many nations. The meaning of lieutenant differs in different militaries (see comparative military ranks), but it is often subdivided into senior (first lieutenant) and junior (second lieutenant and even third lieutenant) ranks. In navies, it is often equivalent to the army rank of captain; it may also indicate a particular post rather than a rank. The rank is also used in fire services, emergency medical services, security services and police forces. Lieutenant may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is " second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieutenant governor in various g ...

Lighter Than Air
A lifting gas or lighter-than-air gas is a gas that has a density lower than normal atmospheric gases and rises above them as a result. It is required for aerostats to create buoyancy, particularly in lighter-than-air aircraft, which include free balloons, moored balloons, and airships. Only certain lighter than air gases are suitable as lifting gases. Dry air has a density of about 1.29 g/L (gram per liter) at standard conditions for temperature and pressure (STP) and an average molecular mass of 28.97 g/mol, and so lighter-than-air gases have a density lower than this. Gases used for lifting Hot air Heated atmospheric air is frequently used in recreational ballooning. According to the Ideal gas law, an amount of gas (and also a mixture of gases such as air) expands as it is heated. As a result, a certain volume of gas has a lower density as the temperature is higher. The average temperature of air in a hot air balloon is about . Hydrogen Hydrogen, being the li ...

Lipoteichoic Acid
Lipoteichoic acid (LTA) is a major constituent of the cell wall of gram-positive bacteria. These organisms have an inner (or cytoplasmic) membrane and, external to it, a thick (up to 80 nanometer) peptidoglycan layer. The structure of LTA varies between the different species of Gram-positive bacteria and may contain long chains of ribitol or glycerol phosphate. LTA is anchored to the cell membrane via a diacylglycerol. It acts as regulator of autolytic wall enzymes ( muramidases). It has antigenic properties being able to stimulate specific immune response.Lipoteichoic acid's chemical signals is C28H74O37P3=OH. LTA may bind to target cells non-specifically through membrane phospholipids, or specifically to CD14 and to Toll-like receptors. Binding to TLR-2 has shown to induce NF-κB expression(a central transcription factor), elevating expression of both pro- and anti-apoptotic genes. Its activation also induces mitogen-activated protein kinases (MAPK) activation along with pho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lymphotoxin Alpha
Lymphotoxin-alpha (LT-α) formerly known as tumor necrosis factor-beta (TNF-β) is a protein that in humans is encoded by the ''LTA'' gene. Belonging to the hematopoietic cell line, LT-α exhibits anti-proliferative activity and causes the cellular destruction of tumor cell lines. As a cytotoxic protein, LT-α performs a variety of important roles in immune regulation depending on the form that it is secreted as. Unlike other members of the TNF superfamily, LT-α is only found as a soluble homotrimer, when found at the cell surface it is found only as a heterotrimer with LTβ. LT-α has a significant impact on the maintenance of the immune system including the development of secondary lymphoid organs. Absence of LT-α leads to the disruption of gastrointestinal development, prevents Peyer's patch development, and results in a disorganized spleen. As a signaling molecule, LT-α is involved in the regulation of cell survival, proliferation, differentiation, and apoptosis. L ...

Lambda Theta Alpha
Lambda Theta Alpha Latin Sorority, Inc. () is a Hispanic and Latino Americans, Latina-based sorority, established in 1975 at Kean University by seventeen women of Latin, Caribbean, and European descent as a support system for women in higher education. According to their website, Lambda Theta Alpha states that its focus would be to "actively integrate itself into the social, political and community service arena that other students had been involved with." The sorority was a member of the National Association of Latino Fraternal Organizations, and won recognition as Sorority of the Year from 2000–2001, 2002–2003, 2003–2004, 2009–2010, 2011–2012, 2012–2013 and 2013– 2014. History Seventeen women came together to form the sorority and are recognized as the 17 Founding Mothers. According to the Sorority's website, Lambda Theta Alpha is recognized as the first Latina sorority in the United States. Lambda Theta Alpha partakes in traditions such as havin ...

Molecular Sieves
A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can. As a mixture of molecules migrate through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of highest molecular weight (which are unable to pass into the molecular pores) leave the bed first, followed by successively smaller molecules. Some molecular sieves are used in size-exclusion chromatography, a separation technique that sorts molecules based on their size. Other molecular sieves are used as desiccants (some examples include activated charcoal and silica gel). The pore diameter of a molecular sieve is measured in ångströms (Å) or nanometres (nm). According to IUPAC notation, microporous materials have pore diameters of less than 2 nm (20 Å) and macroporous materials have pore diameters of gre ...

Aluminosilicate
Aluminosilicate minerals ( IMA symbol: Als) are minerals composed of aluminium, silicon, and oxygen, plus countercations. They are a major component of kaolin and other clay minerals. Andalusite, kyanite, and sillimanite are naturally occurring aluminosilicate minerals that have the composition Al2 Si O5. The triple point of the three polymorphs is located at a temperature of and a pressure of . These three minerals are commonly used as index minerals in metamorphic rocks. Naturally occurring microporous, hydrous aluminosilicate minerals are referred to as zeolites. Feldspar is a common tectosilicate aluminosilicate mineral made of potassium, sodium, and calcium cations surrounded by a negatively charged network of silicon, aluminium and oxygen atoms. The catalyst silica-alumina is an amorphous substance which is not an aluminosilicate compound. Aluminosilicate glasses There exist a wide variety of glass types. The characteristics of these different types depend on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Línea Turística Aereotuy
Linea Turistica Aereotuy LTA, C.A. was a Venezuelan regional and domestic airline headquartered in Caracas and based at Simón Bolívar International Airport. History The airline was established in 1982 and started operations on June 30 of the year. It was part of a full service safari company with its own lodges, camps, guides, aircraft and sailing vessels and operated services to remote destinations in Venezuela, including tourist attractions. It had 300 employees by March 2010. In October 2014, the airline was forced to suspend its flights to Aruba, affecting more than 7,000 customers. The airline's suspension was due to a failure in an aircraft that covered the route, however the National Institute of Civil Aviation indicated that the suspension was due to the over-sale of tickets for said route, as well as the creation of new unauthorized flights to cover the over-sale. This suspension was maintained until February 28, 2015. In February 2016, it was announced that LTA w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
