Cropping Structures Adjustments Under Water Limitations in the Egyptian Agriculture

Using programming methods, the two models of cropping structures suggested by the study were remarkably different. The first model considered water availability levels, while the second tried to optimize its use. As such, some cash crops were excluded from the second model as water extensive users, such as some kinds of fruits. Hence, the second type models expected net revenues and benefit-cost ratios dropped to nearly one-third the corresponding estimates of the first type, and about 10-20% higher than those of the actual cropping structures in average. Accordingly, encouraging farmers to adopt cropping patterns of rational water use would be in vain unless fortified by taxation tools and guidance toward efficient methods of cost reduction and/or yields promotion.Crop Production/Industries,

Responses of Egyptian Food Crops Producers to New Economic Policies: Cases of Wheat and Rice

The formerly neglected wheat production is recovering under policies of economic reform and liberalization. The most effective factors are the continuous price raises and the relatively low production costs which should continue, along with attempts to improve yields and reduce costs, if to avoid imports re-expansion. As for rice, its production expansion potentials are constrained by water limitations. However, the ongoing price increases may motivate attempts to reduce both production costs and post-harvest enormous losses. Exports may be promoted as such, hardly threatening satisfaction of domestic needs, at least in the foreseen future.Crop Production/Industries,

Spectral relationships of the integral equation with logarithmic kernel in some different domains

In this work, the Fredholm integral equation (FIE) with logarithmic kernel is investigated from the contact problem in the plane theory of elasticity. Then, using potential theory method (PTM), the spectral relationships (SRs) of this integral equation are obtained in some different domains of the contact. Many special cases and new SRs are established and discussed from this work

Biomimetic Potentials for Building Envelope Adaptation in Egypt

AbstractBiomimicry is a science that seeks sustainable solutions by emulating nature's time-tested 3.8 billion years of patterns and strategies. The paper is concerned with embodying the biomimetic strategies to building envelopes which shall offer a high potential to reduce the energy demand, save material and thus improve the sustainability of buildings, through accessing current practices process of natural ventilation biomimicry in buildings for a potential application in building envelope for environmental adaptation which could help for the emergence of a new generation of biomimetic building envelopes aiming at promoting biomimicry in Egypt by showing the benefits that could be harvested
