Kinetic and Surface Properties of alpha-synuclein : Investigating the Difference between Pure Peptide and Phospholipid Including Aggregates
Popular summary Parkinson's Disease is a disorder caused by brain that affects patients' coordination, movement as well as causing tremor. The onset of Parkinson's Disease is found to be the large fibrillar aggregates in the brain which consists mostly alpha-synuclein protein. The disease propagation has also been ass…
SEMIFLUORINATED AROMATIC ETHER POLYMERS SEGMENTED WITH POLYETHYLENE GLYCOL (PEG)
Aromatic trifluorovinyl ether (TFVE) monomers are the precursors for perfluorocyclobutyl (PFCB) aryl ether polymers and fluoroethylene/vinylene alkyl/aryl ether (FAE) polymers. PFCB aryl ether polymers are prepared by 2π + 2π cycloaddition of aromatic TFVE monomers. FAE polymers are prepared by nucleophilic addition o…
Predicting The Performance Parameters of In[sub 2]S[sub 3]∕MEH-PPV Heterojunction Using Photoluminescence Technique
Photoluminescence (PL) technique has been put into use for analysing In2S3/MEH‐PPV heterojunction for the first time. Strong luminescence of the polymer absorber MEH‐PPV has been exploited here to predict the properties of the cell. The underlying theory is the dependence of PL intensity on quasi Fermi level separatio…
Влияние состава смешанных растворов ПАВ в перхлорэтилене на моющую способность и смачивание
In the article the comparison between a method of definition of capillary characteristics of textile materials and a method of definition of washing ability of binary solutions of PEAHENS is presented. Surface active agents (surfactants) chemical compounds that are concentrated at the interface, cause a decrease in su…
Approaching to nanostructures using basic concepts of quantum mechanics
In this work we discuss some concepts of quantum mechanics showing the result for the ground state energy of the infinite potential well that, together with elementary thermal physics concepts applied to semiconductors, help us to estimate the size of nanostructures. The energy value of the infinite potential well is…
Теоретическое обоснование антирадоновых призабойных систем вентиляции на урановых рудниках
Theoretical foundation of antiradon ventilation effectiveness rising at uranium mines is given. A number of aerodynamic nozzles which help to raise range and aerodynamical qualities of ventilation stream to carry radon from purifying bottoms out is suggested
Синтез новых бис-малеинимидов на основе алкилароматических диаминов
Maleamic acids have been received by the interaction of diamines on the basis of alkilaromatic phenols and ethers of alkilen-bis-N-amino benzoic acid with maleic anhydride. New bismaleinimides with alkilaromatic bridges have been received by ring formation of maleamic acids with acetic anhydride. Physical and spectral…
Photophysical and Photochemical Investigations of New Tunable Luminescent METL-Metal Bonded Exciplexes
The photophysical and photochemical properties of NaCu(CN)2 and KCu(CN)2 in bulk and doped in alkali halide hosts have studied. In addition, heterometallic interaction between d10-d10 (Cu(CN)2--Au(CN)2- and Cu(CN)2--Ag(CN)2-) and d8-d10 (Ni(CN)42--Cu(CN)2-, Pd(CN)42--Cu(CN)2- and Pt(CN)42--Cu(CN)2-) doped in alkali ha…
Effects of Water Absorption before Molding on Degradation Behavior of Hemp Fiber Reinforced Composites under Hot Water
In this paper, the degradation behavior under hot water of the hemp fiber reinforced thermosetting resin composite materials was examined. Especially, the effects of drying condition for hemp fiber before molding on the mechanical property and degradation behavior of the composites were investigated. In composite mate…
Иcпользование оптического способа измерений для определения предельных деформаций по толщине при разрушении листовых термопластов
Article describes methodic of determination of the limit strains of fracture in sheet materials in case of unibeaxial tension. Geometrical relaxation after fracture is taken into account. Results obtained are in use for calculation of Forming Limit Curves of sheet materials. FLC will be applied in calculation and frac…
О возможности использования озона для облагораживания тяжелого нефтяного и газоконденсатного сырья
Despite sufficiently high effectiveness of hydrogenation processes of purification of oil stock from sulfurous compounds, they have a few drawbacks, some of which are irreparable loss of valuable sulfur organic compounds during the process of hydrogenolysis, high cost of the process and usage of expensive catalysts. A…

Some embedding theorems for functions belonging to Sobolev spaces with mixed summability powers are proved.
The influence of copper on thermal and biochemical activity of silicate-phosphate glasses
Thermal and biochemical activities of glasses from the SiO2-P2O5-K2O-MgO-CaO system modied with the addition of CuO were studied. The glasses can act as slowly dissolving fertilizers, supplying macroelements P, K, Mg, Ca and microelements in a form of copper for plants. Thermal characteristics of the glasses was carri…
