Abstract:

The claims of the traditional texts and teachers of Buddhist meditation include the enhancement of mental health. Twenty five meditators sitting a ten day retreat in Vipassana and Metta meditation were measured on a compassion scale and an androgyny index. The androgyny index was used to measure mental health. Compassion scores for all meditators increased slightly after the retreat. Experienced meditators had significantly higher scores than inexperienced meditators. Regardless of previous experience, meditators with high compassion scores significantly increased in androgyny after the retrea

Abstract:

Numerous applications of heavy metal have caused to their wide contamination in the environmental system and raised serious concerns over potential harmful effects on public health and the environment. Water, sediment, and dietary food are the main exposure media of heavy metal pollution and key determinants of adverse human and environmental health effects. Heavy metal(s) toxicity and speciation involve various mechanistic features with specific media and some of them are not clearly investigated. In particular, biological effects such as toxicity are not related to the total concentration o

Abstract:

Open pore metal foams with moderate porosity (0.6 – 0.7) may be of interest as regenerators due to their high volumetric heat capacity and large specific surface area. Replication process is a low cost and simple foam manufacturing method which provides moderate porosity metal foams. Due to its simplicity, it provides many opportunities to investigate the effect of porosity, pore size and shape or their combination. In this study, this process was used to manufacture metal foams. A method, called vacuum-gas, was the standard method for manufacturing metal foams in the University of Sheffield M

Abstract:

Studies have shown that Co and Cr particles and ions can enter the bloodstream and accumulate in tissues and organs of patients after metal-on-metal (MM) total hip arthroplasty (THA). These ions can generate reactive oxygen species (ROS) that can be deleterious for cells. We first assessed the biological effects of Cr(VI), Co(II), and Cr(III) by testing their effect on antioxidant enzymes (SODs, CAT, GPx, HO-1) that represent a primary defense system against ROS. We demonstrated that Cr(VI) induced the protein expression (translation) of antioxidant enzymes, whereas it had no effect on the mRN

Between 1830 and 1968 Glasgow was home to one of the world’s largest producers of Cr-based chemicals. Chromite ore processing residue (COPR) arising from the factory was used as infill material across large areas of SE Glasgow, resulting in widespread land contamination with Cr(VI), a known human carcinogen of significant mobility. This thesis presents the results of a research project into the bioaccessibility of Cr in Glasgow soils, using a physiologically based extraction test (PBET). 27 Samples were analysed, four of which had a Cr concentration above the residential SGV (200 mg/kg).

Abstract:

Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like cancer, keratosis, gangrene, diabetes, cardio- vascular disorders, etc. Therefore, removal of these pollutants from soil, water and environment is of great importance for human welfare. One of the possible eco-friendly solutions to this problem is the use of microorganisms that can accumulate the heavy metals from the contaminated sources,

Metal oxide nanoparticles (MONPs) are increasingly being incorporated in domestic and industrial products.

The aim of this study was to investigate the behaviour and effects of two MONPs with different solubilities on terrestrial organisms in soils.

Metal dusting mechanisms for iron and nickel-based alloys have been proposed but, nevertheless, have not been agreed upon and numerous modifications to them have been suggested.
