Growth of inclined fatigue cracks using the biaxial CJP model [PDF]

open access: yesFracture and Structural Integrity, 2015
The CJP model of crack tip stresses is a modified version of the Williams crack tip stress field which takes account of simplified stress distributions that arise from the presence of a zone of plastic deformation associated with the crack flanks and ...

Quantitative structure-property relationship studies for the prediction of the vapor pressure of volatile organic compounds [PDF]

open access: yesJournal of the Serbian Chemical Society, 2019
A theoretical model (QSPR) using multiple linear regression analysis for predicting the vapor pressure (pv) of volatile organic compounds (VOCs) has been developed. A series of 51 compounds were analyzed by multiple linear regression analysis. First, the

Exploring Porcine Precision-Cut Kidney Slices as a Model for Transplant-Related Ischemia-Reperfusion Injury

open access: yesTransplantology, 2022
Marginal donor kidneys are more likely to develop ischemia-reperfusion injury (IRI), resulting in inferior long-term outcomes. Perfusion techniques are used to attenuate IRI and improve graft quality.

A novel method for isolation and culture of primary swine gastric epithelial cells

open access: yesBMC Molecular and Cell Biology, 2021
Background Culturing primary epithelial cells has a major advantage over tumor-derived or immortalized cell lines as long as their functional phenotype and genetic makeup are mainly maintained.

Development of an Improved Method for the Isolation and Culture of Newborn Sheep Primary Hepatocytes

open access: yesCurrent Issues in Molecular Biology, 2022
The liver plays a crucial role in metabolism, synthesis, biotransformation, secretion, and excretion. Hepatocytes are the main cells of the liver and can be used as a cell model to study liver function.

Anti-Dengue: A Machine Learning-Assisted Prediction of Small Molecule Antivirals against Dengue Virus and Implications in Drug Repurposing

open access: yesViruses, 2023
Dengue outbreaks persist in global tropical regions, lacking approved antivirals, necessitating critical therapeutic development against the virus. In this context, we developed the “Anti-Dengue” algorithm that predicts dengue virus inhibitors using a ...

Extrinsic mortality and senescence: a guide for the perplexed

open access: yesPeer Community Journal, 2023
Do environments or species traits that lower the mortality of individuals create selection for delaying senescence? Reading the literature creates an impression that mathematically oriented biologists cannot agree on the validity of George Williams ...

Intelligent modeling of hydrogen sulfide solubility in various types of single and multicomponent solvents

open access: yesScientific Reports, 2023
This study aims to study the solubility of acid gas, i.e., hydrogen sulfide (H2S) in different solvents. Three intelligent approaches, including Multilayer Perceptron (MLP), Gaussian Process Regression (GPR) and Radial Basis Function (RBF) were used to ...

Predation has small, short-term, and in certain conditions random effects on the evolution of aging

open access: yesBMC Ecology and Evolution, 2021
Background The pace of aging varies considerably in nature. The best-known explanation of the evolution of specific rates of aging is the Williams’ hypothesis suggesting that the aging rate should correlate with the level of extrinsic mortality. However,
