Effect of changing strain rate on flow stress during hot deformation of type 316L stainless steel [PDF]

open access: yes, 2008
ompression testing has been used with ramped changes in strain rate during deformation, and with changes in strain rate between double deformations to study their effects on flow stress.

Assessment of drought tolerance of some Triticum L. species through physiological indices

open access: yesCzech Journal of Genetics and Plant Breeding, 2012
Wheat is one of the most important crops in the world. Its yield is greatly influenced by global climate change and scarcity of water in the arid and semi-arid areas of the world.

Creation of cotton mutant library based on linear electron accelerator radiation mutation

open access: yesBiochemistry and Biophysics Reports, 2022
Cotton (Gossypium spp.) is one of the most important cash crops worldwide. At present, new cotton varieties are mainly produced through conventional cross breeding, which is limited by available germplasm.

Contact effects in bending affecting stress and formability [PDF]

open access: yes, 2010
If a strip is pulled over a curved tool there is a contact stress acting on the strip. This contact stress changes the stress state in the material, which is analysed with a simple model.

CD36 facilitates fatty acid uptake by dynamic palmitoylation-regulated endocytosis

open access: yesNature Communications, 2020
The mechanistic details of fatty acid uptake into cells remains poorly understood. Here, the authors identify CD36 internalization via cavaeolae and demonstrate dynamic palmitoylationof CD36 is required for endocytic uptake of fatty acids.

Transcriptome profiling revealed potentially important roles of defensive gene expression in the divergence of insect biotypes: a case study with the cereal aphid Sitobion avenae

open access: yesBMC Genomics, 2020
Background Many insects can develop differential biotypes on variable host plants, but the underlying molecular factors and mechanisms are not well understood. To address this issue, transcriptome profiling analyses were conducted for two biotypes of the

Stability of pulse-like earthquake ruptures [PDF]

open access: yes, 2019
Pulse-like ruptures arise spontaneously in many elastodynamic rupture simulations and seem to be the dominant rupture mode along crustal faults. Pulse-like ruptures propagating under steady-state conditions can be efficiently analysed theoretically, but ...

Paspalines C–D and Paxillines B–D: New Indole Diterpenoids from Penicillium brefeldianum WZW-F-69

open access: yesMarine Drugs, 2022
Five new indole diterpenoids named paspaline C–D (1–2) and paxilline B–D (3–5), as well as eleven known analogues (6–16), were identified from fungus Penicillium brefeldianum strain WZW-F-69, which was isolated from an abalone aquaculture base in Fujian ...

Proto-oncogene Src links lipogenesis via lipin-1 to breast cancer malignancy

open access: yesNature Communications, 2020
Altered lipid metabolism has been associated with tumour malignancy, but underlying mechanisms are not clear. Here the authors show that proto-oncogene Src interacts and phosphorylates metabolic enzyme phosphatidic acid phosphatase LPIN1 (lipin-1) to ...

Pentacyclic Cytochalasins and Their Derivatives from the Endophytic Fungus Phomopsis sp. xz-18

open access: yesMolecules, 2021
Eight new cytochalasins 1–8 and ten known analogs 9–18 were isolated from the endophytic fungus Phomopsis sp. xz-18. The planar structures of the cytochalasins were determined by HR-ESI-MS and NMR analysis.
