In the article the features of formation of products from coarse-grained ceramics, poorly compressible masses. To evaluate the molding properties of ceramic materials used in the rheological characteristics: viscosity, fast and slow modules reversible deformation, elasticity, relaxation time, and plasticity. The ways…
We present the data on three (according to Rabotnov classification) apomictic Alchemilla-species coenotypes: patients which are strong edificators, addotors, and explerents with weak reactivity. Phytocoenotic diagnosing features identifying the Alchemilla species with a particular coenotype are presented. The coenotyp…
[Objective] The study aimed to seek for enzyme processing technology without changing the existing process conditions of making the stem-silk,so as to improve the immanent quality of tobacco stem-silk.[Method] Based on the existing technology of making stem-silk and the existing process conditions of washing stem,thro…
The article is devoted to the problem of reception by methods of powder metallurgy of essentially new products with a certain set of physicomechanical properties. Considering last trends in a science, there is possible a reception of new results in the field of nano-dimensional powder materials. The main objective con…

Thermal rectification is a phenomenon in which thermal transport along a specific axis is dependent upon the sign of the temperature gradient or heat current. This phenomenon offers improved thermal management of electronics as size scales continue to decrease and new technologies emerge by having directions of prefer…
У роботі обгрунтовується і пропонується математична модель руху аеродисперсних потоків в коліні трубопроводу. Отримано рішення цієї моделі за умов, наближених до реальних. Наведено порівняння результатів, отриманих експериментально, по даній моделі і для деяких спрощуючих гіпотез.
Self-assembled Ge quantum dots (QD) are grown on Si(100)-(2×1) with laser excitation during growth processes by pulsed laser deposition (PLD). In situ reflection-high energy electron diffraction (RHEED) and post-deposition atomic force microscopy (AFM) are used to study the growth dynamics and morphology of the QDs. A…

Предложен более простой по сравнению с существующими технологиями способ создания трехмерного гибкого высокочастотного микроиндуктора на основе полиимидной пленки с протравленными треками быстрых тяжелых ионов, заполненными проводящим материалом. Создан действующий макет микроиндуктора размером 0,04 мм3, имеющий следу…
Phosphorescent organic light-emitting devices based on polymers have recently been widely studied owing to its high efficiency. The research in this essay also focuses on this topic with the particular concentration on the synthesis, characterization and investigation of opto-electronic properties of the new carbazole…
Целью данной работы является разработка способа литья полых заготовок из силумина с высокодисперсной микроструктурой на их внутренних поверхностях.
Цель данной работы – исследование влияния количества гартцинка в насыщающей смеси на толщину цинкового слоя, изменения размеров и массы после термодиффузионной обработки. Объектом исследования являлись толщина цинкового слоя, изменения размеров и массы образцов.
The subject of this thesis is a good indoor climate in swimming pools. It is very important to achieve good indoor climate in swimming pool in order to swimmers and spectators do not have bad effect on their health. The long operational time of envelope constructions can also be possible only in good envi-ronment. The…

In the present work the problem about a temperature mode of the oil pipeline is considered at its stop. The given problem is actual because of severe environmental conditions in which oil pipelines in Russia, and as owing to specificity of a chemical compound of the oil extracted on a number of deposits in Russia lie.…
The loads acting on the linear part of main oil pipelines and the internal forces in the material of pipes are considered for complicated loading conditions. Refs. 3. Figs. 3. Tabs. 3.
Reduktori su neizostavan element većine strojeva u današnje vrijeme, bilo po pitanju smanjenja broja okretaja ili povećanju okretnog momenta, rabe se za prijenos momenta s pogonskog vratila na pogonjeni uređaj. Ovisno o stroju ili aplikaciji gdje se ugrađuju, potrebno je dobro poznavati strojarsku pozadinu, jer odabir…
Lost foam casting is a relatively new process in commercial terms and is widely used to produce defect free castings owing to its advantages like producing complex shape and acceptable surface finish. In the present research, experimental investigations in lost foam casting of aluminium-silicon cast alloy, LM6, were c…
