Fundamental issues on discovery and disclosure of evidence

The present study is concerned with the impact of psychological factors, particularly character traits and attitudes, on the traffic accident patterns of young drivers. 101 drivers completed a questionnaire consisting of 206 questions and statements. Factor analysis was used to identify and eliminate non-significant test items, leaving 70 statements defining 14 distinct traits. Age and sex were sh

This chapter describes the architecture of a middleware layer between low-level sensing devices and higher level software layers, to support the requirements of a software infrastructure for networked enterprises. The development of such middleware layer is an important problem, as demonstrated by the number or research papers and the variety of approaches that can be found in literature. The main

Flame flashback from the combustion chamber to the premixing section is a major operability issue when using high H-2 content fuels in lean premixed combustors. Depending on the flow-field in the combustor, flashback can be triggered by different mechanisms. In this work, three flashback mechanisms of H-2/CH4 mixtures were visualized in an atmospheric variable-swirl burner using high speed OH* che

The European electric power industry has undergone considerable changes over the past two decades as a result of more stringent laws concerning environmental protection along with the deregulation and liberalization of the electric power market. However, the pressure to deliver solutions in regard to the issue of climate change has increased dramatically in the last few years and has given rise to

The evaporative gas turbine (EvGT), also known as the humid air turbine (HAT) cycle, is a novel advanced gas turbine cycle that has attracted considerable interest for the last decade. This high-efficiency cycle shows the potential to be competitive with Diesel engines or combined cycles in small and intermediate scale plants for power production and/or cogeneration. A 0.6 MW natural gas-fired EvG

BACKGROUND: To investigate, in a rabbit model, the effect of two different doses of vigabatrin (VGB) on retinal function and morphology. METHODS: Twenty-nine rabbits of mixed strain were divided into two groups, receiving either high-dose (n = 15) or low-dose (n = 14) oral VGB treatment (cumulative dose 29.8 +/- 2.9 g and 14.2 +/- 0.6 g respectively). Ten rabbits receiving water served as control

The modeling of soot formation and oxidation under industrially relevant conditions has made significant progress in recent years. Simplified models introducing a small number of transport equations into a CFD Code have been used with some success in research configurations simulating a reciprocating diesel engine. Soot formation and oxidation in the turbulent flow is calculated on the basis of a

Epidemiological studies reveal growing evidence that most cases of Alzheimer`s Disease (AD) likely involve a combination of genetic and environmental risk factors. Identifying and validating these risk factors remains one of the most critical scientific challenges. Several diseases appear to have strong implications for neurodegeneration leading to dementia. This risk encompasses different forms o

Popular Abstract in Swedish Benskörhet (osteoporos) är en sjukdom som karaktäriseras av låg benmassa och försämrad benkvalitet, en sjukdom som leder till ökad risk för frakturer. Benskörhetsfrakturer uppkommer vanligen i handleder, axelleder, kotor, bäckenben, höftleder och knäleder. Frakturerna drabbar kvinnor oftare än män, något som till stor del beror på att nivåerna av det kvinnliga könshormoThe aim of this thesis was to identify the influence of calcium, physical activity and detraining on bone mass and bone size in girls and young women. We hypothesised that calcium intake above a specific level does not enhance the accrual of bone mineral, that exercise predominantly influences the skeleton in the early pubertal period and that reduced training is followed by a loss of exercise-ind

Pre-treatment of sludge before anaerobic digestion can increase methane production and degradation of organic matter. There are various pre-treatment methods for this purpose. Anaerobic digestion tests were performed for comparison of three pre-treatment methods (hygienisation, ultrasonic treatment and enzyme dosing) used separately or in combination on biosludge and mixed sludge. COD solubilisati
