This study utilized eight years of crossbreeding data at this station to compare the number of pigs produced by different mating systems using Duroc, Hampshire and Yorkshire breeds. Mating systems were defined to include the purebred and crossbred herds. These were herds required to produce replacement breeding stock for commercial pig production for a particular two-breed terminal, two-breed r...

A Gram-negative, strictly anaerobic, halophilic, motile, sporulating and rod-shaped bacterium, designated strain HY-42-06T, was isolated from tidal flat sediment from Ganghwa Island in South Korea. The isolate produced glycerol, ethanol and CO2 as fermentation end-products from glucose. Strain HY-42-06T grew optimally at 35 degrees C, pH 7.5 and 3 % (w/v) artificial sea salts. No growth was obs...

This work evaluates the effects of sulfide phase location on zeolite-containing catalysts in cyclohexene hydroconversion using infrared operando technique. Parallels between activity, product yield, and surface species changes with time stream under pyridine poisoning were assessed pure HY zeolite, sulfided NiMo/HY, NiMo/Al2O3, NiMo/Al2O3 + HY. Isomerization activity could be related to zeoliti...

Catalytic conversion of waste rubbers and plastics into aromatic hydrocarbons is a promising approach to management energy recovery. In the present study, acidic HY zeolites were supported by cobalt, iron, zirconium, catalysts characterized powder X-ray diffraction, nitrogen adsorption-desorption, ammonia temperature programmed desorption, photoelectron spectroscopy, pyridine-Fourier transform ...

hyalomma and haemaphysalis are two most important genera of ticks (acari: ixodidae). the rapid and accurate identification of field collected specimens is crucial in faunal works, laboratory assays, anti-tick vaccine experiments, etc. the present study was designed to introduce a rapid and more sensitive method for the differentiation of closely related hyalomma and haemaphysalis species namely...

b a ckground: ticks are important vectors of human and animal pathogens. they are considered as main vectors fortransmission of many viral, bacterial, rickettsial and parasitical pathogens. the aim of the present study was to find out species diversity of ticks, which infested the domestic ruminants in zabol county, eastern iran in 2012. m e t hods: ticks were selected randomly from sheep, goat...

T here are those who want us to believe that, given sufficient time, the human Y-chromosome (HY) will disappear (Graves, 2006). Their reasoning is simple and straightforward. Owing to lack of recombination the HY has degenerated in size and number of genes during its 300 million years of splendid isolation and there is nothing to prevent this process from continuation towards its impending demi...

The first Chinese operational Ku-band scatterometer on board Haiyang-2A (HY-2A), launched in August 2011, is designed for monitoring the global ocean surface wind. This study estimates the quality of the near-real-time (NRT) retrieval wind speed and wind direction from the HY-2A scatterometer for 36 months from 2012 to 2014. We employed three types of sea-surface wind data from oceanic moored b...
