Structural and Semantic Features of People’s Memoirs in Internet Communication

People’s memoirs as a speech genre of Internet communication are discussed. The definition of people’s memoirs is given as memoirs, the author of which is not a professional writer, but an ordinary native speaker. The purpose of the author is dictated, firstly, by the linguistic interest in the study of memoirs from the perspective of one of the most actively developing directions of modern linguistics - genre studies within the context; secondly, by the need of studying the laws of change of the traditional (which had originally a paper base) genres in the process of developing the new communication space. The novelty of the research is seen in the fact that for the first time in this paper, Internet-genre of people’s memoirs acts as a linguistic object of study - along with existing philological tradition of the study of literary genre and traditional speech genre beyond the professional literary creativity. The structural-semantic parameters of Internet-genre of people’s memoirs are analyzed according to genre model developed by L. Yu. Shipitsina. In the framework of the description of these parameters the structural organization of the genre is set and described, as well as the content embodied in its structural elements. It is proved that the structural and substantial features of Internet genre of people’s memoirs are subject to modification compared to the traditional genre of people’s memoirs with a paper substrate

Effect of parameters of heat treatment on magnetic properties and magnetization distribution in ribbons of amorphous soft magnetic iron-based alloys

The effect of the isothermal-holding temperature and cooling rate upon in-air heat treatment on the magnetic properties and magnetization distribution in ribbons of amorphous soft magnetic iron-based alloys with positive saturation magnetostriction has been investigated. The results of the investigation showed that the dependence of the maximum magnetic permeability on the isothermal-holding temperature correlates with the corresponding changes in the magnetization distribution in the ribbon and is determined by diffusion processes that occur upon in-air heat treatment at a specific isothermal-holding temperature. An increase in the cooling rate leads to an ambiguous effect on the level of magnetic properties. The increase favors an improvement in magnetic properties when, after in-air heat treatment, either a predominantly amorphous state of the surface or a state with the formed amorphous-crystalline surface layer with a nearly optimal thickness is obtained. © 2013 Pleiades Publishing, Ltd

Suppression of hole-hole scattering in GaAs/AlGaAs heterostructures under uniaxial compression

Resistance, magnetoresistance and their temperature dependencies have been investigated in the 2D hole gas at a [001] p-GaAs/Al$_{0.5}$Ga$_{0.5}$As heterointerface under [110] uniaxial compression. Analysis performed in the frame of hole-hole scattering between carriers in the two spin splitted subbands of the ground heavy hole state indicates, that h-h scattering is strongly suppressed by uniaxial compression. The decay time $\tau_{01}$ of the relative momentum reveals 4.5 times increase at a uniaxial compression of 1.3 kbar.Comment: 5 pages, 3 figures. submitted to Phys.Rev.

ACTUAL CHARACTERISTICS DETERMINATION OF PHOTOVOLTAIC POWER GENERATION

The work was done to evaluate the possibility of solar energy introduction in the Ural region. An experiment using CETC NES36-5-60M photovoltaic panel was conducted. The actual characteristics for the panel were determined. Based on the results obtained, the conclusions about the relevance of using solar panels in the Urals were done.Данная работа была проделана с целью оценки возможности внедрения солнечной энергетики в Уральский регион. Для этого был произведен эксперимент, в котором использовалась фотоэлектрическая панель CETC NES36-5-60M. Для нее были определены фактические характеристики, и на основе полученных результатов сделаны выводы об актуальности применения солнечных панелей на Урале

A bacterial effector counteracts host autophagy by promoting degradation of an autophagy component

Beyond its role in cellular homeostasis, autophagy plays anti- and promicrobial roles in host-microbe interactions, both in animals and plants. One prominent role of antimicrobial autophagy is to degrade intracellular pathogens or microbial molecules, in a process termed xenophagy. Consequently, microbes evolved mechanisms to hijack or modulate autophagy to escape elimination. Although well-described in animals, the extent to which xenophagy contributes to plant-bacteria interactions remains unknown. Here, we provide evidence that Xanthomonas campestris pv. vesicatoria (Xcv) suppresses host autophagy by utilizing type-III effector XopL. XopL interacts with and degrades the autophagy component SH3P2 via its E3 ligase activity to promote infection. Intriguingly, XopL is targeted for degradation by defense-related selective autophagy mediated by NBR1/Joka2, revealing a complex antagonistic interplay between XopL and the host autophagy machinery. Our results implicate plant antimicrobial autophagy in the depletion of a bacterial virulence factor and unravel an unprecedented pathogen strategy to counteract defense-related autophagy in plant-bacteria interactions
