The work is devoted to the analytical substantia-tion of protection technological means and tools from gas-abrasive impact. It shown that in order reduce friction force, main wear factor, it necessary apply hard thin coatings with microelasticity surface.

Wood flux (piece number per time interval) is a key parameter for understanding wood budgeting, determining the controlling factors, and managing flood risk in river basin. Quantitative data critically needed to improve of dynamics estimate discharge rivers. In this study, streamside videography technique was applied detect passage measure instantaneous rates transport. The goal better understa...

Photosynthesis is an essential part of the plant function and metabolism and a number of herbicides inhibit certain photosynthetic activities. The aim of this study was to evaluate the effect of some herbicides including Topik, Titos, Equip, Mister, Lumax, Bromicide and Oltima on the photosynthetic efficiency of three corn cultivars (CC-260, 400, 704) in response to salicylic acid (SA) treatmen...

in this paper a new form of the homptopy perturbation method is used for solving oscillator differential equation, which yields the maclaurin series of the exact solution. nonlinear vibration problems and differential equation oscillations have crucial importance in all areas of science and engineering. these equations equip a significant mathematical model for dynamical systems. the accuracy o...

The notions of column and row operator space were extended by A. Lambert from Hilbert spaces to general Banach spaces. In this paper, we use column and row spaces over quotients of subspaces of general Lp-spaces to equip several Banach algebras occurring naturally in abstract harmonic analysis with canonical, yet not obvious operator space structures that turn them into completely bounded Banac...

This paper describes a method to register a moving (principal) camera, given a set of fully calibrated static cameras (witnesses) viewing a dynamic scene, a common scenario in broadcasting and film production. Our ultimate aim is to equip the existing free-viewpoint video algorithms with the ability to exploit any available moving cameras in generic dynamic scenes, and to facilitate 3D content ...
