Abstracts: The vascular endothelium produces a large number of vasodilator and vasoconstrictor compounds which regulate vascular tone. Nitric Oxide (NO) is recognised to be the most important and best characterised mediator; its intrinsic vasodilator function is commonly used as a surrogate index of endothelial functi…

Many cancer treatment protocols regard doxorubicin as a one of the most effective anticancer agents available to treat different types of cancer. Its mechanisms of action include either intercalation with the DNA of the cancerous cells, production of reactive oxygen species ROS or it acts by inhibition of topoisomeras…
The analysis of body composition is a broadly applied approach used to evaluate the health condition of the human body, with a view to improving the quality of life, physical activity and sport performance. This study focused on a body analysis of three categories of women athletes, handball players, skaters, swimmers…
The photostability of PVC films phenylphrine HCl acid complexes was investigated.PVC reacts with phenyl phrine HCl acid (L) in THF to prepare PVC-L compound, which characterized by various spectroscopic methods.PVC-L has been reacted with different metal ions to form PVC-L-M II complexes.The structures of these comple…
Abstract The influence of cutting on the surface roughness and undulation of AMg2 aluminum alloy with regular and ultrafine grain structure is considered. The quantitative influence of profile filters on its surface roughness and undulation is established, on the basis of 2D parameters. In the machining of materials w…
The eastern German state of Saxony-Anhalt has opened its first hydrogen refueling station, in the state capital Magdeburg, while the Bavarian capital Munich has opened its third station, in the latest additions to the nationwide network in Germany.
In this work we theoretically introduce and experimentally examine a novel type Bessel-like beams which have an intensity distribution spherically modified by a polarization structure when compared to standard Bessel beams. Standard Bessel-Gaussian beams can be either linearly or radially and azimuthally polarized. He…
This paper addresses the modelling of PMSM under high frequency PWM control. The high frequency components of input voltage have different responses in terms of induced current and iron losses, due to eddy currents in the magnets, phase conductors and in the core lamination. Both inductance and HF iron loss behavior o…
A new class of photoactive poly(hydroxyl-amino ether)s P1a-d & P2a-d based on diarylidene-epoxy moieties were synthesized by ring opening polymerizations of diarylidene epoxy monomers 2a-d during the reaction with 4,4'-diamino diphenyl methane (DDM) or 4,4'-diamino diphenyl ether (DDE). Diarylidene-epoxy monomers 2a-d…
The goals of construction of the BIGR reactor, which was commissioned in 1977 at the All-Russian Scientific Research Institute of Experimental Physics, are reviewed. The primary avenues of research at BIGR are outlined. A brief description of the neutron-physics parameters of the reactor and the characteristic shapes…
Fungal mediated biological synthesis of magnesium oxide nanoparticles (MgO-NPs) is a new approach and eco-friendly technique in context to green nanotechnology. The fungal isolate Aspergillus sp. was used for biosynthesis of magnesium oxide nanoparticles by using Mg (NO3)2.6H2O as a precursor. This fungal isolate was…
Objective: Nanotechnology is one of the greatest breakthroughs in the field of science and technology that have numerous applications that are essential, nowadays. This study was conducted to synthesize ZnONps from carrageenan and characterized the carrageenan with ZnONps using UV-VIS, SEM and FTIR. Material and metho…
Hot forging and machining by forging press is the traditional processing method of automotive universal joint outer race. The method has several disadvantages, such as high energy consumption, over-burning and oxidation tendency of the workpiece, large machining allowance, low surface quality, and poor mechanical prop…

Copper is relatively soft metal and its wear and corrosion are considered to be a major factors of degradation of this metal. For this reason, when the higher wear and corrosion properties are needed, surface properties should be improved with different surface treatments. One of these methods is the applying of Ni-P…
Various scientific researches proved that the most important macro and microelements for human health are potassium, calcium, iron, magnesium. Sugar beet molasses (SBM), which is a concentrated liquid extract and a by-product of sugar refining, is full of mentioned macro and micronutrients. The aim of the research is…
