The objective of the present study was to determine factors affecting body condition score (BCS) and its association with productive and reproductive performances in Holstein cows. Mixed model analysis was performed on monthly records of BCS from April 2006 to July 2012 comprising 34666 records from 3134 dairy cows in a large commercial dairy herd under arid climatic conditions of Isfahan in Ir...

1. Introduction Recent advances in photonic cross-connect (XC) systems and their associated switch fabrics are remarkable [1], [2]. Some photonic switches are reported to allow for an abundant switching capability beyond 1000×1000 at the optical path (OP) level. However, the rationale for such large-scale switches has not yet been proven from the viewpoint of network management or operation. Wa...

Drosophila Wingless (Wg) is the founding member of the Wnt family of secreted proteins. During the wing development, Wg acts as a morphogen whose concentration gradient provides positional cues for wing patterning. The molecular mechanism(s) of Wg gradient formation is not fully understood. Here, we systematically analyzed the roles of glypicans Dally and Dally-like protein (Dlp), the Wg recept...

the aim of this research is to analyze the performance of 8 drought’s index in isfahan, kerman and yazd province and choose the best index. for this purpose, used monthly and yearly rainfall data in the period of 30 years (1985-2014) and also used 8 drought indexes in 20 meteorological stations of central iran which the accuracy of each index in determining drought is examined. also zoning in a...

Understanding and quantitatively evaluating the regional impacts of climate change and variability (e.g., droughts) on forest ecosystem functions (i.e., water yield, evapotranspiration, and productivity) and services (e.g., fresh water supply and carbon sequestration) is of great importance for developing climate change adaptation strategies for National Forests and Grasslands (NFs) in the Unit...

The purpose of this study was determine the selectivity properties of gillnet used in Roach (Rutilus rutilus) fishery in the Lake Uluabat. In the fishery works, 7 different gill net which were 100 meters in length and 32, 40,50, 60,70,80 and 90 mmmesh size with a same thickness and depth of 50 mesh as vertically have been used. Field work was carried out monthly in a period of January 2011 and ...
