In this scientific research, magnesium oxide (MgO) nanoparticles were synthesized from magnesium nitrate and ammonium solutions via microwave@sol-gel process. The structure and the morphology of the synthesized nanoparticles has been identified and characterized by X-ray diffraction (XRD), N2-BET (Brunauer-Emmett-Tell), scanning electron microscopy (SEM) and fourier transform infrared (FTIR) te...

Four phenylalanine nitrogen mustards were tested against the S91 Cloudman mela noma in young male mice. Two of the mustards carried the di (2-chloroethyl) amino group in the meta position but differed in respect to the location of the amino group in the alanine side chain. Likewise, two of the mustards carried the di(2-chloroethyl)amino group in the para position, again differing, however, in l...

BACKGROUND Progress in maternal and neonatal mortality has been slow in many countries despite increasing access to institutional births, suggesting deficiencies in the quality of care. We carried out a systematic assessment of the quality of maternal and newborn care in three CEE/CIS countries, using an innovative approach to identify priority issues and promote action. METHODS A standard-ba...

Austrian foreign direct investment (FDI) increased quickly since 1992. The profitability of these investments did improve over the full period under consideration (1992 to 2005). In particular investments in Central and Eastern Europe became rather profitable. In 2005 total annual profits translate into an average return on equity (RoE) of 8.3%. However, returns differ to a large extent by regi...

Fe(0 0 1) thin films (70 ( A) with Fe(7.2 ( A) tracer layers at the interface were epitaxially grown on GaAs(4 6) surfaces. Magneto-optic Kerr effect and Ferromagnetic resonance measurements indicate a dominant 2-fold in-plane magnetic anisotropy (easy axis along [1 1 0]) superimposed to a 4-fold anisotropy, and small coercivity (B10Oe). M . ossbauer (CEMS) measurements indicate no magnetic ‘‘d...

Compounds incorporating the tetrathiafulvalene (TTF) donor unit and one or two cyanoethynylethene (CEE) acceptor units were prepared by Knoevenagel condensations of highly unstable, TTF-linked propargylic aldehyde or ketone derivatives. The resulting TTF-CEEs are very strong chromophores with low-energy end-absorptions beyond 900 nm. The molecules experience reversible oxidations of the TTF uni...

in this work, zncao2 (zinc oxide-calcium oxide) nanocomposite were synthesized at different temperatures (500-700°c) by sol-gel method based on polymeric network of polyvinyl alcohol (pva). the synthesized samples were characterized by sem/edax, ft-ir and xrd techniques. it was found that synthesized nanocomposites have 1.62, 2.05 and 13.91%wt of cao, respectively. the obtained results show tha...

Background: Numerous studies have been conducted on humans, animals, and cell cultures exposed to Sulfur Mustard (SM). However, the precise mechanism and cause or long-term pattern of SM injuries are not well defined. There is no protocol available for treating people with severe eye, lung, and skin ailments. The current study aimed to develop an animal model of the acute and delayed complicati...
