Oxidative Stress, Nitric Oxide, and Diabetes [PDF]

open access: yesThe Review of Diabetic Studies, 2010
In the recent decades, oxidative stress has become focus of interest in most biomedical disciplines and many types of clinical research. Increasing evidence from research on several diseases show that oxidative stress is associated with the pathogenesis of diabetes, obesity, cancer, ageing, inflammation, neurodegenerative disorders, hypertension ...

Characteristics of Ozone Production by Using Atmospheric Surface Glow Barrier Discharge

open access: yesWalailak Journal of Science and Technology, 2011
Ozone is a strong oxidizer that can kill bacteria and other micro-organisms very effectively. In the recent years, ozone has become very important for sterilization of water used in shrimp farming and treatment of wastewater from food industry.

Combustion Characteristics of a Swirl-Radial-Injection Composite Fuel Grain with Applications in Hybrid Rockets

open access: yesAerospace, 2023
The combustion characteristics of a swirl-radial-injection composite fuel grain were experimentally and numerically investigated. This composite grain permits swirl-radial oxidizer injection based on three hollow helical blades, each having a constant ...

Modeling and analytical simulation of high-temperature gas filtration combustion

open access: yesJournal of Applied Sciences and Environmental Management, 2017
High temperature filtration in combustion and gasification processes is a highly interdisciplinary field. Thus, particle technology in general has to be supported by elements of physics, chemistry, thermodynamics and heat and mass transfer processes ...

Crystal structure of bis(fluorosulfato-κO)xenon(II), Xe(SO3F)2

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
Thermally unstable Xe(SO3F)2 has been prepared by the reaction of XeF2 with HSO3F. Single crystals were obtained from HSO3F by slow cooling in a sealed tube.

Synthesis Gas Composition Prediction for Underground Coal Gasification Using a Thermochemical Equilibrium Modeling Approach

open access: yesEnergies, 2020
Underground coal gasification (UCG) is an in situ conversion technique that enables the production of high-calorific synthesis gas from resources that are economically not minable by conventional methods. A broad range of end-use options is available for

Oxidative stress: oxidants and antioxidants [PDF]

open access: yesExperimental Physiology, 1997
An imbalance between oxidants and antioxidants in favour of the oxidants, potentially leading to damage, is termed ‘oxidative stress’. Oxidants are formed as a normal product of aerobic metabolism but can be produced at elevated rates under pathophysiological conditions. Antioxidant defense involves several strategies, both enzymatic and non‐enzymatic.
