Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel. Water contamination of lubricants is often considered as

Background: Systemic Lupus Erythematosus (SLE) is an autoimmune disease encompassing a wide range of symptoms that can emanate from pathology in virtually any organ system. Severe SLE includes involvement of the central nervous system and kidneys. One of the hallmarks of the disease is a multitude of autoantibodies, indicating a breakdown in self tolerance. The corresponding antigens have been fou

There are many reasons why heat transfer and heat exchangers play a key role in the development of sustainable energy systems as well as in the reduction of emissions and pollutants. In general, all attempts to achieve processes and thermodynamic cycles with high efficiency, low emissions, low costs include heat transfer and heat exchangers to a large extent. It is known that sustainable energy de

The physicochemical properties of two root suspensions, parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius), were studied and compared at different concentrations and after being subjected to processes such as homogenization and heating. The study and the evaluation of the physicochemical properties of these plant materials in the form of pastes might help to increase the interest in t

The state of the farming industry in Europe has been put under the spotlight in recent years due to a number of different food scares and disease outbreaks. Many new quality assurance schemes have been formed to accompany the existing environmental monitoring schemes, to give concerned consumers some guarantee when buying food that it is of a good quality and the environmental load of production h

This work shows a contribution to a long-term study of lead in smelter workers where the objectives were to assess the historical lead (Pb) exposure and to study the relationships between lead concentrations in finger bone (Bone-Pb), whole blood (B-Pb), plasma (P-Pb), urine (U-Pb) and the duration of employment in workers at a secondary lead smelter. Moreover, results were compared with previous s

Pyranose 2-oxidase (P20x) has several proposed biotechnological applications such as a bio-component in biofuel cells or for carbohydrate transformations. To improve some of the catalytic properties of P20x from Trametes multicolor, we selected a semi-rational approach of enzyme engineering, saturation mutagenesis of active-site residues and subsequent screening of mutant libraries for improved ac

One of the most important trends in contemporary tourism is the increase in urban tourism, both in absolute and in relative terms. An increasing number of cities have become significant tourism destinations. Cities also attract an increasingly diverse set of visitors, some of which could be called alternative tourists. The development of alternative tourism is related to decreasing relative costs
