1. Clothing Evaporative Resistance: Its Measurements and Application in Prediction of Heat Strain
Sammanfattning : Clothing evaporative resistance is one of the most important inputs for both the modelling and for standards dealing with thermal comfort and heat stress. It might be determined on guarded hotplates, on sweating manikins or even on human subjects. LÄS MER
2. Occupational heat exposure and kidney disease - Studies on the role of heat stress in the Mesoamerican epidemic of Chronic Kidney Disease of non-traditional origin
Sammanfattning : This thesis examines the association between heat stress and kidney disease in Mesoamerica using different perspectives and methods. An ecologic study found that hot, sugarcane-cultivating regions had elevated chronic kidney disease (CKD) mortality. LÄS MER
3. Monotonic and Cyclic Plastic Deformation of High-Strength Aluminium Alloys
Sammanfattning : Dynamic strain ageing (DSA) and dynamic precipitation (DP) are two, closely interrelated, phenomena arising from the dynamic interaction between mobile solute atoms and dislocations. The occurrence of DSA and DP is confined to specific ranges of strain rate and temperature, and aluminium alloys are generally prone to experience DSA and DP already at ambient temperatures and conventional strainrates.

4. Corrosion testing of heat exchanger tubing
Sammanfattning : Heat exchanger tubes are commonly made from stainless steel.In a heat exchanger both the process fluid and the cooling orheating media can be corrosive. It is therefore important to beable to select materials that do not suffer from corrosion.Current methods in this area, however, suffer from limitationsand shortcomings. LÄS MER
5. The Plastic Flow Behaviour of Aluminium Alloys Exhibiting Dynamic Strain Ageing
Sammanfattning : The phenomenon known as dynamic strain ageing, abbreviated DSA, has been known since the beginning of last century. It was first discovered as serrations in the load-elongation curve obtained upon deforming specimens of certain alloys in tension. This phenomenon became known as the Portevin-Le Chatelier (PLC) effect. LÄS MER
