In order to study the bacterial flora of dead-in-shell ostrich chicks, twelve unhatched eggs which did nothave external pipping during the hatching period were transferred to the laboratory of microbiology. The eggshells were accurately disinfected and the embryos were removed and placed in a sterile plate. The surface of each embryo was swabbed with a sterile swab which was also plunged throug...
Yolk sac infection (YSI) and dead-in-shell mortality caused by Enterobacteriaceae in birds are not a rare phenomenon, however there are only a few reports indicating the association between these conditions and Klebsiella spp. among canary chicks (Serinus canaria). There have been reports of high mortality among 1-3 day old canary chicks in an indoor flock of canaries. In order to study the cau...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
The present work was carried out to isolate and identify fungi species present in dead-in-shell chick embryo. A total of three thousand dead-in-shell embryonated chicken eggs pooled into 300 eggs (10 eggs per group) were collected from the four hatcheries over a period of six months. The contents of the pooled eggs were inoculated onto Sabourauds Dextrose Agar (SDA) and Corn Meal Agar (CMA) sla...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
In this research, hydrodynamic distribution pressure in continuous times is done and stress and displacement of a high speed vessel are studied. Hydrodynamic distribution pressure is studied for different dead rise angle according to vertical and horizontal vessel velocity at dry chine and wet time steps and is applied to vessel at continues times of vessel variable position. Vessel body is div...
