avian leukosis viruses (alvs) cause different types of tumours in poultry and can affect the health and egg production of the birds. to investigate the presence of the virus in chicken layer flocks in shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...

I review some aspects of supersymmetric grand unification and emphasize a recent development in the area of gauge coupling unification.

This paper presents the digital interactive experience system of the Jing-Hang Grand Canal of China and introduces some related work. The purpose of this system is to attract users’ interests in the history and culture of the Jing-Hang Grand Canal. We provide users with virtual exhibition and virtual exploring environment which make it possible that the disappeared ancient scenes and stories re...

We show that an intermediate gauge symmetry breaking scale can be a significant source of electric dipole moments for the electron and neutron in supersymmetric grand unified theories. New phases, similar to that of the CKM matrix, appear which do not arise from the supersymmetry (SUSY) breaking operators. To illustrate, we choose some grand unified SUSY models having an intermediate gauge symm...

GF677 rootstock (peach ×almond) is an important rootstock for peach. It was produced by Bernhard in French at Grand Farad Research Centre in 1965. The present study focused on the effect of some PGRs on propagation and root induction on GNH medium as part of providing an applicable protocol for micro-propagation of mentioned rootstock. Results indicated that BAP at concentration of 0.5 mg/l plu...

This paper deals with the amount of disorder that is left in a permutation after one of its elements has been selected with quickselect with or without median-of-three pivoting. Five measures of disorder are considered: inversions, cycles of length less than or equal to some m, cycles of any length, expected cycle length, and the distance to the identity permutation. “Grand averages” for each m...

A Supersymmetric Grand unified model is constructed based on SO(10)xSO(10) symmetry in which new types of Yukawa matrices couple standard and exotic fermions. Evolution of these couplings from the Grand Unified scale to the electroweak scale causes some of them to be driven to their fixed points. This solves the supersymmetric alignment problem and ensures that there are no observable flavor ch...

PURPOSE In modern days, grand multiparity is confined to communities where contraception is not practiced because of social and religious beliefs. For this reason, it is quite prevalent in all GCC countries. Few studies have compared the outcomes between the three groups: low parity (2-4), grand multiparity (5-9), and great grand multiparity (10 and more) . This study intended to analyze the tr...

“One of the better aspects of human nature is our drive to seek out and conquer challenges. We seem imbued with a desire to formulate problems of the highest degree of difficulty and then to relentlessly pursue their solution. The identification and pursuit of Grand Challenges has been a hallmark of the high-performance computing arena for over a decade. In recent years, many other technical co...
