espanolKyliniella latvica Skuja es un rodofito de amplia distribucion pero escasamente citado debido a su caracter estacional. Su presencia siempre esta ligada a ambientes bajos en nutrientes, y podria considerarse un buen indicador de oligotrofia. La especie ha sido recolectada en lagos y arroyos de America y Europa.…
The collective of authors leads experimental researches on assessments of bactericidal action new disinfectant preparations on example E. coli by results of the lead researches all preparations had pernicious an effect on E. coli, bactericidal action in 0,5 % concentration possessed: OMDEZ-1, OMDEZ-2, SKAT-ED-1, MUK-D…
For the first time identified features reokinetic curing prepolymer polydienurethan brand «Krasol NN23» glycerin and it is shown that this process is a multistage, because of the different functional reactants. Revealed that up to the point of the structure formation occurs miсrogel homogeneously in the kinetic region…
In this article species structure and ecological and geographical characteristics of diatoms algae of phytobenthos of the Ingoda, the Shilka, the Onon, the Borsiy, the Turga and the Aga rivers are presented. There are 212 species and forms of diatoms algae in phytobenthos of the rivers
The growing interest in the use of hydrogen as main fuel has increased the need for pure hydrogen (H2) production and purification. There are several by-products (CO, H2O, CO2) associated with the production of hydrogen which might damage the production rate. Therefore, separation of hydrogen from other gases is an im…
Nanotechnology is the science and technology of manipulating materials at atomic and molecular scale with properties different from bulk. Semiconductor QDs are important class of nanomaterials with unique physical and chemical properties owing to the quantum confinement effect. Size dependent optical properties make r…
Codeposition of bismuth and selenium from citrate solutions was investigated by method of stripping voltammetry. The optimum potential of deposition was found. It was shown that in this system is formed heterostructure consisting of a chemical compound Bi 2Se 3 and free bismuth.
The synthesis of new highly porous composite materials, by combining Metal Organic Frameworks (MOFs) and graphene derivatives is described. The porosity of these composite materials is confirmed by pore volume, nitrogen uptake, BET and Langmuir surface area calculations. Structural information for the composites is ac…
The article studies certain suitability aspects of polymeric-textile fabrics, e.g. mechanical-and-physical properties and protective properties. It analyses the results of experimental studies. The complex quality index has been adapted for polymer-textile fabrics comparison
Στην παρούσα διατριβή παρουσιάζεται μεθοδολογία για την αναγνώριση της πρωτεϊνικής αναδίπλωσης η οποία ισοδυναμεί με την εύρεση της δομής του μορίου της πρωτεΐνης στο χώρο. Η μέθοδος είναι πλήρως αυτοματοποιημένη και δεδομένης μιας αλληλουχίας αμινοξέων αγνώστου δομής μπορεί να την ταξινομήσει με υψηλό ποσοστό επιτυχί…
Conservative schemes of approximation equations of total current, continuity, heat conduction and Poisson, used in the simulation of processes of a self-heating up of semiconductor structures in diffusive-drift 1D approach for a basis electric potential free carriers charge concentration are presented. There are resul…

Proces ten zale y od takich parametrow jak: – temperatura, – atmosfera spiekania, – wielko cz stek u ytego proszku, – sposob zag szczenia proszku [2].…
Effects of Crimp and Textile Architecture on the Tensile Response of Composites with 3D Reinforcement
During the time period January-December 2012, 4 members of our university staff from the Goce Delcev University-Stip, Macedonia have realized research study stays in the joint laboratories within the SOE DAAD project MatCatNet. Ass. Professor Violeta Ivanova Petropulos has realized two-weeks stay at the Leipzig Univer…
This article considers the integrated propulsion system, consisting of internal combustion engine with a free piston and linear electrical inductor machine with permanent magnet on the stator. The authors investigate the regenerative mode of the linear inductor machine operation and compare two systems of permanent ma…
Literature data characterizing dependence of a number of thermodynamic properties of substance (heat of phase transition, pressure of saturated vapour, melting temperature, surface tension) on its particles effective radius r have been generalized. Analytical dependence substance heat capacity at constant volume (CV)…
Photovoltaic devices consisting of highly periodic, ultradense, silicon nanowire arrays and nanohole arrays have been fabricated with nominal nanowire widths of 20 nm, nanohole sizes of 12 nm, and lattice pitches of 32 nm, deep in the subwavelength regime for visible light. We have developed a set of surface passivati…
This project continues the work of Daniel White which culminated in the thesis, "A Hot Strip Mill Work Roll Temperature Model", submitted to Cardiff University in 2007. The current project presents a combined thermal solution, incorporating a transient, two-dimensional model which predicts changes in the circumferenti…
The specificity of textile materials, quality and purpose of which is determined by the product of which they are incurred. One of the major modern materials are polymers have been successfully applied to the textile fibers. The modern market economy and improving the technology of textile production open up wider opp…
La caracterisation des mecanismes regulant la migration, la proliferation et la differenciation des keratinocytes lors de la cicatrisation est un enjeu majeur d’un point de vue physiologique et physiopathologique. Dans ce contexte, l’etude de l’implication potentielle des microARNs nous a semble innovante et originale…
