Application of zero-dimensional thermodynamic model for predicting combustion parameters of CI engine fuelled with biodiesel-diesel blends

open access: yesAlexandria Engineering Journal, 2016
Biodiesel from non-edible vegetable oil seems to be a promising alternate for petro-diesel in the present energy scenario. This study analyses the experimental and theoretical effects on the blends of Bee Wax biodiesel with straight diesel on combustion ...

Explosion characteristics of a biogas/air mixtures

open access: yesChemical Engineering Transactions, 2022
An experimental apparatus for the biogas and air mixture explosion in a closed spherical vessel was set up. Biogas-air mixtures were studied experimentally and numerically for different equivalence ratios between 0.25 and 2.4, and initial temperatures of

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Study on the significant effects of ignition energy and gas volume fraction on gas explosion pressure and flame propagation speed

open access: yesMeikuang Anquan
The maximum flame propagation speed, the peak pressure and the pressure rise rate of gas explosion were studied under the influence of two factors of ignition energy and gas volume fraction, by using the orthogonal experimental method in a closed ...

Effects of each operating condition on the underwater shock waves driven by imploding detonation and microorganism treatment experiments

open access: yesJournal of Thermal Science and Technology, 2015
In recent years, microorganisms contained in ship ballast water have been identified as vectors for the destruction of marine ecosystems. To control such microorganisms, various techniques are being developed and tested.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

The rate of rise of alveolar carbon dioxide pressure during expiration in man. [PDF]

open access: yesThe Journal of Physiology, 1982
1. The purpose of the study was to see whether the rate of rise of alveolar PCO2 (PA, CO2) in expiration was directly proportional to the rate of pulmonary elimination of CO2 (VCO2) in man in the steady state. 2. Alveolar ventilation at rest and during exercise in man was calculated from the difference between total ventilation and dead space ...
