Seasonal variations of zooplankton communities were studied in the southern Caspian Sea for 4 successive seasons and 8 transects with 5 stations from 5 to 100 m depths which sampled during 2009. The zooplankton population constituted of 73.33% copepods, 24.21% rotifers, 2.23% cladocerans and 0.23% protozoans. Copepods were dominant at all stations with a density between 1456±531 ind. m-3 (Trans...

Thitarodes pui larvae have a limited distribution in the Tibetan Plateau and are the host of a parasitic fungus, Ophiocordyceps sinensis. Low temperature is a main environmental stress. However, understanding of T. pui cold adaptation mechanisms is insufficient. Delta-9-acyl-CoA desaturase (D9D) is closely correlated with cold adaptation for many organisms. To further understand the cold adapta...

saqqez, located in a specific geographical area with its own topographical and climatic conditions, has a cool climate. with long-lasting frosts, the town has imposed harsh bio-climatological circumstances on the residents. on the basis of the results derived from the building thermal request, it was determined that the weather in saqqez is definitely cold about 43.7 percent of the year, and th...

This study analyzes six frontal dust storms in the Middle East during cold period (October–March), aiming to examine atmospheric circulation patterns and force dynamics that triggered fronts associated (pre- or post-frontal) storms. Cold troughs mostly located over Turkey, Syria north Iraq played a major role front propagation at surface, while cyclonic conditions strong winds facilitated The p...

The broad aim of this study was to determine whether bedding level in the transport trailer influenced pig performance and welfare. Specifically, the objective was to define the bedding requirements of pigs during transportation in commercial settings during cold and mild weather. Animals (n = 112,078 pigs on 572 trailers) used were raised in commercial finishing sites and transported in traile...

A total of 65 multiparous cows that calved during the hot season (n = 21), temperate season (n = 23) or cold season (n = 21) were used to investigate the relationships between heat stress, seasonal changes, metabolic traits, body condition score (BCS), resumption of ovulation and occurrence of subclinical endometritis (SE). Cows were monitored for the first 7 weeks of lactation by ultrasonograp...

in order to identify different types of effective weather on patterns of inversion in mashhad, the researchers first prepared the inversion statistics, then, the sea level pressure and finally they prepared access to the zero meeting gmt cumulative 2.5 degrees in the range 20 to 47.5 degrees to 67.5 degrees north and 35 east center, university ncep angelia east of england norwich city. then for...

The objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. Given the increasing demand for higher steel...
