background: toxoplasma gondii is a zoonotic protozoan parasite found worldwide and responsi­ble for major economic losses in most classes of livestock. this study was aimed to deter­mine the prevalence of t. gondii infection in sheep, cattle and horses in urmia, north-west of iran, using mat. methods : blood samples of 276 livestock and 26 horses were collected from july 2009 till april 2010. t...

We investigated the mechanism of nitric oxide (NO) action on hepatic methionine adenosyltransferase (MAT) activity using S-nitrosoglutathione (GSNO) as NO donor. Hepatic MAT plays an essential role in the metabolism of methionine, converting this amino acid into S-adenosylmethionine. Hepatic MAT exists in two oligomeric states: as a tetramer (MAT I) and as a dimer (MAT III) of the same subunit....

HTM-MAT is a MATLAB® based toolbox for implementing cortical learning algorithms (CLA) including related cortical-like algorithms that possesses spatiotemporal properties. CLA is a suite of predictive machine learning algorithms developed by Numenta Inc. and is based on the hierarchical temporal memory (HTM). This paper presents an implementation of HTM-MAT with several illustrative examples in...

Effect of nanosilver (NS) on the heat-transferring rate to the core section of medium density fiberboard (MDF) mat was studied here. A 400 ppm aqueous nanosilver suspension was used at three consumption levels of 100, 150, and 200 mL/kg, based on the weight of dry wood fibers; the results were then compared with the control MDF panels. The size range of nanosilver was 30-80 nm. Results showed t...

We have reviewed information on early-, late- and limit-value decomposition stages for litter of Norway spruce (Picea abies) Scots pine (Pinus silvestris). This synthesis covers c 16 studies/papers made along a climatic gradient; range in mean annual temperature (MAT) from ?1 to +7 °C precipitation (MAP) 425 1070 mm. has an early stage dominated by carbohydrate late lignin; just one lignin deco...

Microbes form mats with architectures that promote efficient metabolism within a particular physicochemical environment, thus studying mat structure helps us understand ecophysiology. Despite much research on chemolithotrophic Fe-oxidizing bacteria, Fe mat architecture has not been visualized because these delicate structures are easily disrupted. There are striking similarities between the bio...

Black band disease (BBD) is a virulent polymicrobial disease primarily affecting massive-framework-building species of scleractinian corals. While it has been well established that the BBD bacterial mat is dominated by a cyanobacterium, the quantitative composition of the BBD bacterial mat community has not described previously. Terminal-restriction fragment length polymorphism (T-RFLP) analysi...

The study of yeast mating-type (MAT) gene switching has provided insights into several aspects of the regulation of gene expression. MAT switching is accomplished by a highly programmed site-specific homologous recombination event in which mating-type-specific sequences at MAT are replaced by alternative DNA sequences copied from one of two unexpressed donors. The mating-type system has also pr...

Comparative tests were conducted in an environment-controlled farrowing room (21 ° C, 70 ° F) to determine the choice of mat heat vs. lamp heat by piglets in farrowing crates. Two widened farrowing crates (2.40 × 2.13 m, 8 × 7 ft.) were used, each equipped with two double-size heat mats (0.6 × 1.2 m or 2 × 4 ft, 120 W capacity each). One mat was powered to provide the localized heat, while the ...
