Modeling patterns of wealth disparity in predynastic Upper Egypt
The archaeological record shows that from ca. 4000 BC onwards, Neolithic farming communities in Upper Egypt underwent a process of increasing social complexity. This included a rise in wealth inequality and hierarchy, settlement agglomeration, and the development of complex cultural ideology, all leading eventually to the emergence of a unified territorial state encompassing the whole Nile Vall...
متن کاملThe effect of different combinations of dietary energy and protein on the composition of ostrich eggs
Abstract Nutrition of breeding female birds can influence egg quality and is therefore extremely important for the development of the embryo and the successful hatching of a high quality chick. We investigated the effect of combining different levels of dietary energy and protein, with accompanied amino acid levels, in the diets of female ostriches on the composition of their eggs. Ninety pairs...
متن کاملThe effects of storage temperature and position on embryonic mortality of ostrich (Struthio camelus) eggs
The present study was carried out with the aim of determining the effects of storage temperature and storage position on embryonic mortalities in ostrich eggs. A total of 229 ostrich eggs was collected from two commercial ostrich farms. The effects of storage temperature on embryonic mortality differed. Embryonic deaths (totalled for early, medium and late incubation) were determined at respect...
متن کاملFactors related to shell deaths during artificial incubation of ostrich eggs.
The ostrich industry experiences a high rate of embryonic mortalities during artificial incubation of eggs. Embryonic deaths were studied from data recorded on 37,740 fertile eggs incubated artificially during the 1998-2005 breeding seasons. Roughly 10,000 eggs that sustained embryonic mortalities were classified according to the stage and nature of death, i.e. before 21 days of incubation, aft...
متن کاملPhysical Characteristics, Chemical Composition and Fatty Acid Profile of Ostrich Eggs
A study was conducted to assess the physical characteristics, chemical composition and fatty acid profile of ostrich eggs. Fifteen eggs were collected randomly and used for the conduct of study. Studies revealed the average size to be 1435.1 ± 20.10 g, length 151.5 ± 0.83 mm, width 113.6 ± 0.34 mm, shell thickness 2.56 ± 1.12 mm and shape index 74.2 ± 0.82. Three principal components amounted t...
