Regulation of transcription elongation in response to osmostress [PDF]

open access: yes, 1967
Cells trigger massive changes in gene expression upon environmental fluctuations. The Hog1 stress-activated protein kinase (SAPK) is an important regulator of the transcriptional activation program that maximizes cell fitness when yeast cells are exposed

THE EFFECT OF LENGTH TIME IN USING POLYAMIDE NETS (PA) MULTIFILAMENT SIZE 210D/15 MESH SIZE ¾ INCH ON THE PART OF THE PURSE SEINE NETS TO THE VALUE OF BREAKING STRENGTH AND ELONGATION

open access: yesRussian Journal of Agricultural and Socio-Economic Sciences, 2021
Fishing gear consists of natural materials (natural fibres) and synthetic materials (synthetic fibres). The advantage of using synthetic materials is more durable. Polyamide is one of the examples of synthetic materials or also known as nylon.

Evaluation of properties of elastomer seal for fuel systems exposed to effects of rapeseed methyl ester

open access: yesResearch in Agricultural Engineering, 2017
Elastomer seals in fuel systems have to evince required mechanical properties also at exposure to fuels. The aim of the research was to determine an influence of various concentrations of rapeseed methyl ester (RME) on a change of mechanical properties ...

Efficient regeneration of Eucalyptus urophylla from seedling-derived hypocotyls

open access: yesBiologia Plantarum, 2010
Seedling hypocotyls were used as explants to establish a regeneration protocol for Eucalyptus urophylla and N-phenyl-N'-[6-(2-chlorobenzothiazol)-yl] urea (PBU), one kind of di-substituted urea, was found useful growth regulator. The hypocotyls incubated

Fossil evidence and stages of elongation of the Giraffa camelopardalis neck [PDF]

open access: yesRoyal Society Open Science, 2015
Several evolutionary theories have been proposed to explain the adaptation of the long giraffe neck; however, few studies examine the fossil cervical vertebrae. We incorporate extinct giraffids, and the okapi and giraffe cervical vertebral specimens in a

Elongating under Stress [PDF]

open access: yesGenetics Research International, 2011
In response to extracellular stimuli, mitogen-activated protein kinases (MAPKs) modulate gene expression to maximize cell survival. Exposure of yeast to high osmolarity results in activation of the p38-related MAPK Hog1, which plays a key role in reprogramming the gene expression pattern required for cell survival upon osmostress.

A Spheroid Model for the Role of Shape in Particle Size Analysis

open access: yesKONA Powder and Particle Journal, 2015
Standard procedure in particle size analysis is to express size as an equivalent sphere diameter. As a consequence, results obtained by procedures based on different kinds of response give different results.

Determination of thermally stressed state of rod elements of variable cross section under the impact of a lateral heat flow, heat exchange and surface thermal insulation [PDF]

open access: yesE3S Web of Conferences, 2020
A horizontal bar of limited length is considered. The radius of the bar changes linearly along its length. The cross-sectional area of the left end is larger than the right. The lateral surface of the investigated rod is completely insulated.
