In this article, we derived an equality for CR-warped product in a complex space form which forms the relationship between gradient and Laplacian of warping function second fundamental form. We necessary conditions submanifolds Ka¨hler manifold to be Einstein impact Ricci soliton. Some classification by using Euler–Lagrange equation, Dirichlet energy Hamiltonian is given. also derive some chara...

The objective of this study is to investigate the removal efficiency of Cr(VI) by Bacillus subtilis, Pseudomonas aeruginosa and Enterobacter cloacae from aqueous solution under different process conditions. Batch mode experiments were carried out as a function of solution pH, biosorbent dosage, Cr(VI) concentration and contact time. The FT-IR spectra and SEM analysis of the biosorbent were reco...

Issues related to the thermal stability of front contacts, based on Cr-Au and Cr-Au-Ag-Au, GaSb-based photovoltaic cells have been considered at operational (the cell temperature is 50 o C) standard conditions as well forced degradation (at 125 200 C). It shown that converter with silver-containing contact preferable in terms resistivity, external quantum yield, FF, V oc , therefore, efficiency...

A set of new chromium(III) [Cr(III)] complexes based on the tridentate ligand HC(Pz)2Py (Pz = pyrazole; Py = pyridine) and its derivatives were prepared, characterized, and evaluated for ethylene polymerization/oligomerization. X-ray single-crystal analyses of the Cr(III) complexes showed tridentate coordination on the fac-octahedral Cr sphere. Upon activation with methylaluminoxane (MAO), the ...

Removal of Cr(VI) from aqueous solutions using biochar from sugar beet tailing (SBT) was investigated as a function of pH, contact time, and biochar mass via batch experiments. The surface characteristics of SBT biochar before and after Cr(VI) sorption was investigated with scanning electron microscopy equipped with energy dispersive X-ray spectroscopy and Fourier transform infrared spectroscop...

A CR-slant warped product is considered a generalization of CR-warped product. It was firstly introduced and studied in the field Kaehler geometry. In this paper, we study products nearly trans-Sasakian manifolds. We obtain general inequality related to second fundamental form warping function such products. The equality case discussed.

There is growing concern about how participation in contact sports affects the brain. Retrospective evidence suggests that contact sports are associated with long-term negative health outcomes. However, much of the research to date has focused on former athletes with significant health problems. Less is known about the health of current athletes in contact and collision sports who have not repo...
