Sar (river)
The Sar is a river in Galicia, Spain. Rising near Santiago de Compostela, it flows through the A Maía valley for over before entering the Ulla (river), Ulla River, near Padrón. Pomponius Mela (d. 45 AD) mentions it (''Sars'') in ''De situ orbis libri III'' and the Galician poet and novelist Rosalía de Castro wrote a well-known collection titled ''En las Orillas del Sar'' ("On the Banks of the Sar") in Spanish language, Castilian Spanish.

Nationwide Suspicious Activity Reporting Initiative
The Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI) is a program of the United States government used to collect and share reports of suspicious activity by people in the United States. The Nationwide SAR Initiative (NSI) builds on what law enforcement and other agencies have been doing for years — gathering information regarding behaviors and incidents associated with criminal activity — but without the customary restrictions on collecting data on individuals in the absence of reasonable suspicion or probable cause. The program has established a standardized process whereby SARs can be shared among agencies to help detect and prevent terrorism-related criminal activity. This process is in direct response to the mandate to establish a "unified process for reporting, tracking, and accessing ARs in a manner that rigorously protects the privacy and civil liberties of Americans, as called for in the ''2007 National Strategy for Information Sharing'' (NSIS), which i ...

Sodium Adsorption Ratio
The sodium adsorption ratio (SAR) is an irrigation water quality parameter used in the management of sodium-affected soils. It is an indicator of the suitability of water for use in agricultural irrigation, as determined from the concentrations of the main alkaline and earth alkaline cations present in the water. It is also a standard diagnostic parameter for the sodicity hazard of a soil, as determined from analysis of pore water extracted from the soil. The formula for calculating the sodium adsorption ratio (SAR) is: : \text = \frac where sodium, calcium, and magnesium concentrations are expressed in milliequivalents/liter. SAR allows assessment of the state of flocculation or of dispersion of clay aggregates in a soil. Sodium and potassium ions facilitate the dispersion of clay particles while calcium and magnesium promote their flocculation. The behaviour of clay aggregates influences the soil structure and affects the permeability of the soil on which directly depends the ...

Semi-automatic Rifle
A semi-automatic rifle is a type of rifle that fires a single round each time the Trigger (firearms), trigger is pulled while automatically loading the next Cartridge (firearms), cartridge. These rifles were developed Pre-World War II, and were used throughout World War II. Rifles are firearms designed to be fired while held with both hands and braced against the shooter's shoulder for stability. Externally similar shotguns can fire multiple Shot (pellet), pellets simultaneously through a smoothbore, while rifle Gun barrel, barrels are Rifling, rifled to spin-stabilize individual bullets. The actions of semi-automatic rifles use a portion of the fired cartridge's energy to eject the spent casing and load a new round into the Chamber (firearms), chamber, readying the rifle to be fired again. This design differs from manually operated rifles such as Bolt action, bolt-action and Lever action, lever-action rifles, which need to chamber a cartridge manually before firing again, and ...

IPCC Second Assessment Report
The Second Assessment Report (SAR) of the Intergovernmental Panel on Climate Change (IPCC), published in 1995, is an assessment of the then available scientific and socio-economic information on climate change. The report was split into four parts: a synthesis to help interpret UNFCCC article 2, ''The Science of Climate Change'' (Working Group I), ''Impacts, Adaptations and Mitigation of Climate Change'' (WG II), ''Economic and Social Dimensions of Climate Change'' (WG III). Each of the last three parts was completed by a separate Working Group (WG), and each has a Summary for Policymakers (SPM) that represents a consensus of national representatives. The SPM of the WG I report contains the following statements: Greenhouse gas concentrations have continued to increase; anthropogenic aerosols tend to produce negative radiative forcings; climate has changed over the past century (air temperature has increased by between 0.3 and 0.6 °C since the late 19th century; this estimate ...

Sterling SAR-87
The Sterling SAR-87 is a military assault rifle of the late 20th century. The Sterling Assault Rifle (SAR), which included elements from Sterling's earlier Light Automatic Rifle (LAR) design, was jointly engineered by Sterling Armaments Company and Chartered Industries of Singapore in the early 1980s as an advanced version of the AR-18 for the export sales. It was also offered to the British Armed Forces, who declined it because they were already in the process of adopting the SA80 bullpup design manufactured by Royal Ordnance Factories. Design The SAR-87 was a robust weapon based on the well tried AR-18 with the versatility of the M16 rifle. It could also be converted from 5.56×45mm NATO to 9×19mm Parabellum by changing the barrel and bolt assembly, to provide a submachine gun for police forces. Sterling Armaments tried to push the rifle, renamed SAR-87, for some more years, but at the end of the 1980s, it was bought out by British Aerospace British Aerospace plc ( ...

SAR 21
The SAR 21 ("Singapore Assault Rifle - 21st Century") is a bullpup assault rifle designed and manufactured in Singapore, chambered for the 5.56x45mm cartridge. First revealed and subsequently adopted by the Singapore Armed Forces (SAF) as its standard service weapon in 1999, it was designed and developed over a four-year period to replace the locally license-built M16S1 by the Ministry of Defence (MINDEF), Singapore Army and the former Chartered Industries of Singapore (CIS), presently ST Engineering Land Systems. Many of its design features are directly intended to address the weaknesses of the M16S1 as encountered operationally by some infantrymen. The rifle is being sold for export use aside from domestic use. In the United States, it was marketed by ST Kinetics via its American subsidiary, VT Systems. History Since the mid-80s, the SAF had an outstanding requirement to replace the M16S1, in use since 1973, in part due to licensing limitations that prevented Singapore fr ...

Sar (astronomy)
The saros () is a period of exactly 223 synodic months, 18 years 11 days and 8 hours, that can be used to predict eclipses of the Sun and Moon. One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. Every eclipse has an associated saros series and all succeeding or preceding eclipses have a different saros series associated with them - as the eclipse of the same series occurs or occurred with a gap of one saros only. Solar and lunar eclipses have different saros series. A series of eclipses that are separated by one saros is called a ''saros series''. It corresponds to: *6,585.321347 solar days *18.029 years *223 synodic months *241.999 draconic months *18.999 eclipse years (38 eclipse seasons of 173.31 days) *238.992 anomalistic months *241.029 sidereal months The 19 eclipse years means that if there is a solar ec ...

Systemic Acquired Resistance
Systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen. SAR is analogous to the innate immune system found in animals, and although there are many shared aspects between the two systems, it is thought to be a result of convergent evolution. The systemic acquired resistance response is dependent on the plant hormone, salicylic acid. Discovery While, it has been recognized since at least the 1930s that plants have some kind of induced immunity to pathogens, the modern study of systemic acquired resistance began in the 1980s when the invention of new tools allowed scientists to probe the molecular mechanisms of SAR. A number of 'marker genes' were characterized in the 1980s and 1990s which are strongly induced as part of the SAR response. These pathogenesis-related proteins (PR) belong to a number of different protein families. While there is substantial overlap, the spectrum of PR proteins expresse ...

Structure–activity Relationship
The structure–activity relationship (SAR) is the relationship between the chemical structure of a molecule and its biological activity. This idea was first presented by Alexander Crum Brown and Thomas Richard Fraser at least as early as 1868. The analysis of SAR enables the determination of the chemical group responsible for evoking a target biological effect in the organism. This allows modification of the effect or the Potency (pharmacology), potency of a bioactive compound (typically a drug) by changing its chemical structure. Medicinal chemistry, Medicinal chemists use the techniques of chemical synthesis to insert new chemical groups into the biomedical compound and test the modifications for their biological effects. This method was refined to build mathematical relationships between the chemical structure and the biological activity, known as quantitative structure–activity relationships (QSAR). A related term is structure affinity relationship (SAFIR). Structure-biodeg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Absorption Rate
Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg). SAR is usually averaged either over the whole body, or over a small sample volume (typically 1 g or 10 g of tissue). The value cited is then the maximum level measured in the body part studied over the stated volume or mass. Calculation SAR for electromagnetic energy can be calculated from the electric field within the tissue as :\text = \frac\int_\text \frac \,d\mathbf, where :\sigma is the sample electrical conductivity, :E is the RMS electric field, :\rho is the sample density, :V is the volume of the sample. SAR measures exposure to fields between 100 kHz and 10 GHz (known as radio waves). It is commonly used to measure power absorbed from mobile phones and during MRI scans. The ...

Sexual Attitude Reassessment
A Sexual Attitude Reassessment, sometimes Sexual Attitude Restructuring (SAR), seminar is a process-oriented, structured group experience to promote participants' awareness of their attitudes and values related to sexuality, and to assist them in understanding how these attitudes and values affect them professionally and personally. Since the primary purpose of a SAR is the examination of attitudes and values, it is not a traditional academic experience designed to disseminate cognitive information, nor is it psychotherapy directed toward the resolution of personal problems. A SAR provides an opportunity for participants to explore and understand their beliefs, attitudes, values and biases within the realm of sex and sexuality. This self-exploration and self-understanding facilitates comfort that ultimately fosters improved communication skills, both on a professional and a personal level. By becoming increasingly aware of their perceptions, beliefs, and feelings, participants be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
