The hydrographical and chemical conditions of Lake Manzalah, Egypt, are influenced by the surging in of saline water from the Mediterranean sea and are by no means stable. The average of the parameters studied during the ...

Let en(T) and an(T) be the entropy numbers and approximation numbers of operator T between Banach spaces, respectively. Let ?p be the operator ideal defined by Sp:^TeL;{en(T)^lp}, and Sp be the operator ideal defined ...

Various samples of the raw materials used in the manufacture of Portland cement in Qatar, the clinker produced and the cement itself were studied by using Mossbauer Effect and X-ray diffraction analysis in order to investigate ...

The magnetic properties and lattice dynamics of the spinel ferrite system Cdx Coi-x Fe^ 04 (x = 0.0, 0.1, . . . , and 1.) were studied in the temperature range between 78 to 800°K. The results showed that the samples with ...

The problem of the propagation of the elastic-plastic wave in the half-space occupied by and elastic-plastic medium has been studied. Treatments were carried out under the Assumption of perpendicular load, on the boundary, ...

Overhead is an incurred cost which is matched against cost objects via an intervening base of allocation. The problem of overhead allocation is to come up with a cost allocation procedure which is objective, applies, ...

In 1955 Nayar described two types of neurosecretory cells in lphita limbata (A- and B-types) [1]. Later, Johannson [2] classified these cells into four categories: A, B, C and D, which he regarded as motor neurones of ...

The effect of treating •y-alumina with hydrofluoric acid on the dehydration reaction of ethanol was investigated at 325°C. The gas chromatographic column was used as a chemical reactor. The rate of formation of ethylene ...
