A basic problem with complexity is that we would like to characterize all complex systems both verbally and mathematically and do so in a clear, concise and distinctive manner, as do scientists with many of the systems found in other fields. Such characterizations are necessary if we are to distinguish complex systems from other kinds of dynamical systems, influence their functioning, forecast ...
The aim of this study was to determine the body measurement of Holstein cows through image analysis (IA) and to estimate their live weight (LW) by means of a fuzzy rule-based model using the body measurements. For this purpose, a photography environment was established at a dairy cattle farm where a large number of cows were kept. First, digital photographs of each animal were synchronously tak...

Understanding the evolution and molecular architecture of complex traits is important in domestic animals. Due to phenotypic selection, genomic regions develop unique patterns of genetic diversity called signatures of selection, which are challenging to detect, especially for complex polygenic traits. In this study, we applied the composite selection signals (CSS) method to investigate evidence...
Harsh conditions, almost desert, only goats and Bedouins could be found all over the North Sinai region. Shammi goats are the common and favorable breed in this region. All animals have the same feeding system based mainly on natural vegetation most of the year. Every midmonth and during one year. Sixty-five Shammi goats were examined to determine the pattern of inner coat fibers. In mid Februa...
After disappointing results from all efficacy trials conducted to date, the field of microbicides research now faces substantial challenges. Poor coordination among interested parties and the choice of nonvalidated scientific targets for phase III studies have hampered progress and created mistrust about the use of microbicides as a method to prevent HIV-1 sexual transmission. Although new prom...
