Auxin and Cellular Elongation [PDF]

open access: yesPlant Physiology, 2016
Auxin is a crucial growth regulator in plants. However, a comprehensive understanding of how auxin induces cell expansion is perplexing, because auxin acts in a concentration- and cell type-dependent manner. Consequently, it is desirable to focus on certain cell types to exemplify the underlying growth mechanisms.

Effect of Al or Cu Content on Microstructure and Mechanical Properties of Zn Alloys Fabricated Using Continuous Casting and Extrusion

open access: yesMetals
The effect of Al or Cu content on the microstructure and mechanical properties of continuous casting and extrusion Zn alloys has been studied by a room temperature tensile test, X-ray diffraction, and scanning electron microscope. With the increase in Al

Influence of the typical vegetation ashes/particles on discharge characteristics of conductor-plane air gap

open access: yesThe Journal of Engineering, 2019
The frequent forest fires become a serious threat to the performance of transmission lines’ external insulation, and large quantities of smoke (carbon black) and flying ashes are produced during the combustion of vegetation, reducing the dielectric ...

Effects of Extrusion and Rolling Processes on the Microstructure and Mechanical Properties of Zn-Li-Ag Alloys

open access: yesMetals, 2022
In this work, a novel Zn-0.5%Li-0.1%Ag alloy was cast and extruded into rods, which were rolled into a plate, and the effects of extrusion and rolling on the microstructure and mechanical properties of the Zn-0.5%Li-0.1%Ag alloy were evaluated.

The Elongation of Ovococci [PDF]

open access: yesMicrobial Drug Resistance, 2014
The morphogenesis of ovococci has been reviewed extensively. Recent results have provided new insights concerning the mechanisms of elongation in ovoid bacteria. We present here the proteins involved in the elongation (firmly established and more or less hypothetical) and discuss the relationship between elongation and division of ovococci.

Brain astrocyte synthesis of docosahexaenoic acid from n-3 fatty acids is limited at the elongation of docosapentaenoic acid

open access: yesJournal of Lipid Research, 2002
The phospholipids, particularly phosphatidylethanolamine, of brain gray matter are enriched with docosahexaenoic acid (22:6n-3). The importance of uptake of preformed 22:6n-3 from plasma compared with synthesis from the α-linolenic acid (18:3n-3 ...

Docosahexaenoic acid synthesis from α-linolenic acid by rat brain is unaffected by dietary n-3 PUFA deprivations⃞

open access: yesJournal of Lipid Research, 2007
Rates of conversion of α-linolenic acid (α-LNA, 18:3n-3) to docosahexaenoic acid (DHA, 22:6n-3) by the mammalian brain and the brain's ability to upregulate these rates during dietary deprivation of n-3 polyunsaturated fatty acids (PUFAs) are unknown. To
