Environmental Isocyanate-Induced Asthma: Morphologic and Pathogenetic Aspects of an Increasing Occupational Disease
2011
Occupational diseases affect more and more people every year. According to the International Labour Organization (ILO), in 2000 an estimated amount of at least 160 million people became ill as a result of occupational-related hazards or injuries. Globally, occupational deaths, diseases and injuries account for an estimated loss of 4% of the Gross Domestic Product. Important substances that are related to occupational diseases are isocyanates and their products. These substances, which are used in a lot of different industrial processes, are not only toxic and irritant, but also allergenic. Although the exposure to higher concentrations could be monitored and restricted by technical means, v…

Background: Emotional dysregulation, measured with face recognition tasks, is prevalent in alcohol use disorders (AUD), constituting a risk factor for alcohol use and relapse. It is not clear howev...
Friction and wear of lubricated M3 Class 2 sintered high speed steel with and without TiC and MnS additives
2005
Abstract M3/2 sintered high speed steel and composite materials processed by initial admixing of 5 wt.% TiC (to decrease wear) and 5 wt.% MnS (to minimise friction) powders, singly and in combination, were assessed in pin-on-disc tribometers specially constructed to simulate use in the automotive valve train. Pins were of the sintered materials and the mating tribological material discs of T1 high speed steel. For comparison with existing conventional materials, identical tests were performed with discs and pins of two types of spheroidal cast iron. Testing at ∼110 °C, employing a few drops of fresh Shell Helix Standard SAE: 15W-40, API: SJ/CF oil, in daily segments of 5000 m of sliding dis…
Early Signs of Mathematics Anxiety?
2012
Abstract Mathematics anxiety refers to individual's negative affect when engaging in numerical and mathematical tasks. Researchers have recently connected high math anxiety to lower performance on math tasks, developmental dyscalculia, and lower self-efficacy towards math learning. Math anxiety scales have been made and validated mainly for secondary school and high school students. In our paper we are looking for early signs of math anxiety using a Pictorial Test (37 pictures) which we have developed for 6 to 8 year old children. Children were asked to concentrate on one picture at a time and to write down spontaneously their emotional and mathematical ideas. Most powerful sources of sadne…
