Recent advances in understanding of magnetohydrodynamic (MHD) turbulence call for revisions in the picture of particle acceleration. We make use of the recently established scaling of slow and fast MHD modes in strong and weak MHD turbulence to provide a systematic study of particle acceleration in magnetic pressure (low-β) and gaseous pressure (high-β) dominated plasmas. We consider the accele...

The development of modern science and technology, improving the level industrialization, increase people's awareness environmental protection were leaded to world's demand for filter materials purify air. This review presented an overview air pollutants classification, history fiber materials, theory filtration traditional (materials, characteristics, advantages, disadvantages, standards). In a...

The formation and presence of clathrate hydrates could influence the composition stability planetary ices comets; they are at heart development numerous complex models, all which include necessary condition imposed by their curves, some cage occupancy or host-guest content hydration number, but fewer take into account kinetics aspects. We measure temperature-dependent-diffusion-controlled carbo...

Al2O3-forming austenitic (AFA) stainless steels are potential replacements for the existing balance of plant (BoP) components in solid oxide fuel cells (SOFCs). In this study, chromium (Cr) poisoning anode supported (ASCs) coupled with various alloys was analyzed by distribution relaxation times (DRT). The performance deterioration ASCs mainly attributed to increased polarization resistances ch...

The source of N(2)O produced in soil is often uncertain because denitrification and nitrification can occur simultaneously in the same soil aggregate. A technique which exploits the differential sensitivity of these processes to C(2)H(2) inhibition is proposed for distinguishing among gaseous N losses from soils. Denitrification N(2)O was estimated from 24-h laboratory incubations in which nitr...

• Increasing application of the indicator-dilution technic to the study of various segments of the circulation has focused attention on the different forms of this teehnic that have been devised" as well as on requirements of the ideal indicator and of the ideal detecting-recording system to be used in such studies. This paper will be largely confined to a discussion of indicators and detectors...

The mixing and combustion of liquid oxygen (LOX) and gaseous methane of a shear coaxial injector operating under supercritical pressures have been numerically investigated. The near-field flow and flame dynamics are examined in depth, with emphasis placed on the flame-stabilization mechanisms. The model accommodates the full conservation laws and real-fluid thermodynamics and transport phenomen...

Two-dimensional (2D) materials are composed of atomically thin crystals with an enormous surface-to-volume ratio, and their physical properties can be easily subjected to the change of the chemical environment. Encapsulation with other layered materials, such as hexagonal boron nitride, is a common practice; however, this approach often requires inextricable fabrication processes. Alternatively...

This investigation into the reactions of Tyroglyphut farinae to varying concentrations of carbon dioxide and oxygen and to the presence of small quantities of hydrocyanic acid, was carried out in order to obtain some insight into the respiratory activities of the mite, very little being known of its physiological reactions. As a necessary preliminary, its reactions to humidity were determined. ...

BACKGROUND Ozone exposure rapidly leads to bacterial death, making ozone an effective disinfectant in food industry and health care arena. However, microbial defenses may moderate this effect and play a role in the effective use of oxidizing agents for disinfection. Serratia marcescens is an opportunistic pathogen, expressing genes differentially during infection of a human host. A better under...
