Ультраструктурные аспекты биологии злокачественного роста саркомы С-45
An integrated morphological research of solid sarcoma S-45 tumor transplanted to mongrel male rats under skin in the back was performed. An electron microscope study revealed two types of sarcoma S-45 cells varying in distinctness. Data on tumor growth kinetics, proliferative activity and ultrustructural composition o…
High Q-factor Ba0.25Sr0.75TiO3 thin film bulk acoustic wave resonators: growth conditions and correlations with microstructure
The electrically tunable thin film bulk acoustic wave resonators (TFBARs), utilizing electric field induced piezoelectric effect in paraelectric phase ferroelectrics, enable development of novel reconfigurable/adaptable circuit architectures. However, the practical applications are hindered by their relatively low aco…

Ценотипы представителей рода alchemilla L. в среднем Поволжье
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…

A Review of Thermal Rectification Observations and Models in SolidMaterials
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…
Analytical investigation into velocity change of the transported material in a pipeline bend
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.
Excitation-Induced Ge Quantum Dot Growth on Si(100)-2X1 by Pulsed Laser Deposition
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…
