Background: Global climate change is already increasing the average temperature and direct heat exposure in many places around the world. Objectives: To assess the potential impact on occupational health and work capacity for people exposed at work to increasing heat due to climate change. Design: A brief review of basic thermal physiology mechanisms, occupational heat exposure guidelines and heat

Popular Abstract in Swedish Människans immunförsvar har utvecklats under miljontals år för att i bästa möjliga mån skydda oss från infektioner och det sköter i de allra flesta fall det jobbet utmärkt. Ibland händer det dock att någonting går fel och konsekvensen kan bli väldigt obehaglig eller till och med förödande för den drabbade. Allergiska reaktioner är ett utmärkt exempel på en sådan situatiAntibodies of the IgE isotype play a key role as the allergen recognizer in allergic disease, which today affects as much as a third of the population in the industrialized parts of the world. Despite this crucial role of IgE, our knowledge of IgE repertoires and how we can utilize the information hidden in monoclonal IgE to improve the quality of life of allergic patients, is limited.

A theory of viscoplasticity is formulated within a thermodynamic concept. The key point is the postulate of a dynamic yield surface, which allows us to take advantage of the postulate of maximum dissipation to derive an associated formulation of the evolutions laws for the internal variables without using penalty techniques that only hold in the limit it when viscoplasticity degenerates to invisci

This paper examines the impact of mutual inductance and parasitic capacitance on the phase-error performance for a class of CMOS quadrature voltage-controlled oscillators (QVCOs). Good agreement is found between theory, post-layout simulations, and measurement results. The QVCOs were implemented in a standard 0.35/spl mu/m CMOS process. All QVCOs display a center frequency of 2 GHz and a tuning ra

We have studied the interaction of light with an array of vertically oriented III-V semiconductor nanowires both theoretically and experimentally. For the theoretical studies, electromagnetic modeling has been employed. This modeling shows that with proper tuning of the nanowire diameter, the absorption per volume semiconductor material can be 20 times higher in the nanowires than in a correspondi

Studies show that women managers are subject to more stressors than are men in comparable positions and in general women also report higher levels of distress symptoms than men do. It is of particular importance to examine the components that can cause strain and mental health problems for female managers. A further aspect of the stress process, that has received increased attention, is coping. Se

The interest in modelling, analysis and optimisation of supply chain structures has increased in the last decade. Among the reasons are globalisation, a general speed-up of the rate of change in the business environment, the trend towards more outsourcing of activities, and the rapid development in IT. This development has caused more and more people to realise the benefits of supply chain managem
