  2. 1. Adjusting to the extreme : Thermal adaptation in a freshwater gastropod

    Author : Magnus Johansson; Laurila Anssi; Robby Stoks; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radix balthica; Lake Mývatn; geothermal springs; thermal adaptation; isolation by environment; population structure; gene flow; cogradient variation; AFLP; thermal preference; CTmax; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Temperature is a ubiquitous force influencing biological processes ranging from cellular responses to life span. The thermal environment for many organisms is predicted to change with globally increasing temperatures and studies conducted in natural systems incorporating various evolutionary forces, such as gene flow, is needed.

  4. 2. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction

    Author : Krishna Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Nicholls John; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. READ MORE

  5. 3. Outdoor thermal comfort of residents in a warm humid climate : A study on informal settlements in Dar es Salaam, Tanzania

    Author : Modest Maurus Baruti; Boende och bostadsutveckling; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Outdoor thermal comfort; Microclimate; Thermal perception; Urbanites; Informal settlements; Informal urban fabric; Warm humid climates; Dar es Salaam; Physiological Equivalent temperature PET ; New Standard Effective Temperature SET* ; Universal Thermal Climate Index UTCI ;

    Abstract : In the informal settlements of warm humid climates, where the majority of urbanites spend most of their time outdoors, a conducive thermal environment is crucial for their social and economic well-being. The overall aim of this thesis is to increase knowledge and understanding of outdoor thermal comfort in informal settlements in the warm and humid climate of Dar es Salaam, Tanzania. READ MORE

  6. 4. Thermal physiology and metabolism : Interplay between heat generation and energy homeostasis

    Author : Gustavo Abreu-Vieira; Jan Nedergaard; Eric Ravussin; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fysiologi; Physiology;

    Abstract : Mammal metabolism is intimately connected to the maintenance of body temperature. While metabolic pathways invariably produce heat as a by-product, the natural heat present in the environment also plays a role in defining the adaptive metabolism and general physiology of an organism.

    Abstract : Temperature is one of the most decisive parameters when it comes to determining characteristics and distributions of life worldwide. For plants, as sessile organisms, it is particularly important to be able to deal with the temperatures they are exposed to at a given location. READ MORE
