Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Dual adaptive strategies in Candida glabrata under tunicamycin stress: petite mutations and chromosome C aneuploidy drive transient drug resistance

open access: yesFrontiers in Microbiology
BackgroundCandida glabrata is an opportunistic fungal pathogen known for its ability to rapidly develop resistance to antifungal agents. Tunicamycin (TUN), an inhibitor of N-linked glycosylation, induces Endoplasmic Reticulum (ER) stress, but the ...

Polymorphism of prolamin proteins in selected varieties of winter wheat registered in the Czech Republic

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
In 2006 and 2007 samples of harvested grain were used to verify the possibility of distinguishing 12 winter wheat genotypes and of detecting impurities on the basis of polymorphism of prolamin kernel proteins.

No wonder, it is a hybrid. Natural hybridization between Jacobaea vulgaris and J. erucifolia revealed by molecular marker systems and its potential ecological impact

open access: yesEcology and Evolution, 2023
Progressive changes in the environment are related to modifications of the habitat. Introducing exotic species, and interbreeding between species can lead to processes that in the case of rare species or small populations threatens their integrity. Given

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Weighted LD surfaces produced by constant admixture.

open access: yes, 2022
The heat maps are from simulations and the contours from analytical results for a model in which continuous admixture started 10, 20, or 40 generations ago and stopped 5 generations before the present.

THE IMPROVEMENT OF CONTROL SYSTEM OF FURNACE EQUIPMENT BY USING THE NEW MATHEMATICAL MODEL OF GAS MIXING

open access: yesИзвестия высших учебных заведений. Поволжский регион:Технические науки, 2020
Backgrounds. The object of the study is the aspects leading to more intensive mixing of the gas, for the most complete combustion of the formed turbulent jet, which is used in combustion processes. The subject of the study is the model for finding the

The effects of a propofol/alfentanil admixture on total intravenous anaesthesia in dogs undergoing splenectomy

open access: yesVeterinární Medicína, 2015
The aim of this study was to compare the cardiovascular and respiratory effects and the bispectral scale index (BIS) as well as the recovery period characteristics in response to treatment with a propofol/alfentanil admixture of different concentrations ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Prospects for Admixture Mapping of Complex Traits [PDF]

open access: yes, 2005
Admixture mapping extends to human populations the principles that underlie linkage analysis of an experimental cross. For detecting genes that contribute to ethnic variation in disease risk, admixture mapping has greater statistical power than family ...
