  1. 1. Too Hot! : an Epidemiological Investigation of Weather-Related Mortality in Rural India

    Författare :Vijendra Ingole; Barbara Schumann; Joacim Rocklöv; Rainer Sauerborn; Sanjay Juvekar; Patrick Kinney; Umeå universitet; []
    Nyckelord :Temperature; heat and cold; mortality; education; socioeconomic status; occupation; rural population; India; folkhälsa; Public health;

    Sammanfattning : BackgroundMost environmental epidemiological studies are conducted in high income settings. The association between ambient temperature and mortality has been studied worldwide, especially in developed countries. LÄS MER

  3. 2. Women's knowledge, attitudes, and management of the menopausal transition

    Författare :Lotta Lindh-Åstrand; Mats Hammar; Karin Kjellgren; Aila Collins; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Menopause; hormone therapy; knowledge; attitudes; conceptions; management treatment; climacteric symptoms; hot flushes; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Introduction: Hormone therapy (HT) has been considered as a safe treatment for menopausal symptoms. Use of HT increased dramatically in the 1980s and 1990s. Results from large randomized clinical trials (RCT) could, around the turn of the century, however not find evidence for long-term benefits with HT. LÄS MER

  4. 3. Hot forming tribology : galling of tools and associated problems

    Författare :Leonardo Pelcastre; Ewald Badisch; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

    Sammanfattning : In recent years, the use of ultra high-strength steels (UHSS) as structural reinforcements and in energy-absorbing systems in automobiles has increased rapidly; mainly in view of their favourable strength to weight ratios. However, due to their high strength, the formability of UHSS is poor, thus complex-shaped UHSS components are invariably produced through hot-metal forming processes. LÄS MER

  5. 4. Hot-carrier extraction in nanowires

    Författare :Jonatan Fast; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Hot carrier; photovoltaic; Thermoelectric; Fysicumarkivet A:2023:Fast;

    Sammanfattning : A hot-carrier solar cell aims to generate power from energetic, photoexcited, charge carriers, so called hot carriers, in order to reach higher conversion efficiencies than current solar cell technology.Creating a hot-carrier solar cell has proven challenging for two main reasons: hot carriers lose their energy very quickly, and they need to be extracted over distances of a few hundrednanometers via energy selective filters.

  7. 5. Chromium martensitic hot-work tool steels : damage, performance and microstructure

    Författare :Johnny Sjöström; Jens Bergström; Farhad Rezai-Aria; Karlstads universitet; []
    Nyckelord :Hot-work tool steel; thermal fatigue; microstructure; Materialteknik; Materials Engineering;

    Sammanfattning : Chromium martensitic hot-work tool steel (AISI H13) is commonly used as die material in hot forming techniques such as die casting, hot rolling, extrusion and hot forging. They are developed to endure the severe conditions by high mechanical properties attained by a complex microstructure. LÄS MER
