The present study investigates the hemotoxic and cytotoxic impacts of two acute doses of silver nanoparticles (AgNPs) on the African catfish, Clarias garepinus in comparison to the impact of AgNO3 and the control fish. AgNPs-induced impacts were recorded on some biological and hematological indices of that species on the bases of their size (20 and 40 nm) and concentration (10 and 100 µg) but no significant interaction. AgNO3 had very low impact on these indices in comparison to AgNPs. Recovery period for 15 days was found to be valid to remove AgNPs and AgNO3 toxicity for most indices. The condition factor exhibited stability under stress whereas the hepatosomatic index was more sensitive to AgNPs. The AgNPs-induced hematological changes recorded were corresponding with different blood cell alterations which increased in frequency from the control and AgNO3 to 40 nm/100 µg; such blood cell alterations disappeared to great extent after recovery period of 15-days in a reverse order

Abu Gharadig (AG) oil and gas field lies in the central portion of the AG basin in the northern part of the Western Desert. The Abu Roash “G” (AR”G”) represents the basal member of the Abu Roash Formation and comprises shale and limestone with interbeds of sandstone. This member may act as a source, reservoir or seal rock. Structural patterns of the AR “G” Member play an important role in the hydrocarbon potentialities and prospect identification in the area. The data available for the present study include four digital wireline logs, 2D seismic sections, well path data, formation tops and a checkshot survey. The goal of the present study was achieved through the interpretation of the 2D seismic sections using petrel schlumberger modeling software. Two-way time (TWT) and depth structure maps were obtained, in addition to the geo-seismic cross-sections. From the present study, it is concluded that the AR “G” Member suffered compartmentalization by a complex series of normal faults along with anticlinal folding. The anticline has NE-SW axis resulting from NW-SE compression. The fault planes have trends range from EW to NW-SE direction. The fold and the NW-SE faults are of Late Cretaceous age and are related to the time of the positive structural inversion through the AG basin. The fold is asymmetric and doubly plunging. The fold changes its asymmetry and plunging from SW to NE. The normal faults form horsts, grabens and half grabens.

In a recent paper [15], Saddeek introduced the so-called class of generalized strictly pseudo-contractive mappings and established some strong convergence theorems for the generalized modified Krasnoselskii iterative processes developed by Saddeek [15] for finding the minimum norm solutions of certain nonlinear equations when p ≥ 2 in the framework of uniformly convex Banach spaces. This paper develops the work presented in [15] by considering separately the case in which 1 p 2:

Abstract. A generalized class of nonlinear multivalued mappings in uniformly convex Banach spaces is introduced and termed generalized K1J-pseudocontractive mapping. Significantly, this class incorporates various other important classes of pseudocontractive mappings in Banach and Hilbert spaces. A duality fixed point theorem for such generalized class of mappings (assuming that it is also generalized Lipschitzian) is constructed by the modified Ishikawa iterative scheme. Finally, an application to the strictly monotone inclusion problem is also discussed. The obtained theorems extend several known results in the literature.

We point out a major flaw in the conformable calculus. We demonstrate why it fails at definning a fractional derivative and where exactly these tempting conformability properties come from.
