  1. 1. Sea Level Compensation System for Wave Energy Converters

    Författare :Valeria Castellucci; Rafael Waters; Ronan Costello; Uppsala universitet; []
    Nyckelord :Ocean energy; Tides; Linear generator; Point absorber; Offshore experiment; Hydro-mechanic modeling; Power absorption; Control system; Communication system; Measurement system; Lysekil research site; Wave Hub.;

    Sammanfattning : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. LÄS MER

  3. 2. Congenital adrenal hyperplasia : pre-and postnatal treatment effects on cognition, behavior and brain resting-state functional connectivity

    Författare :Valeria Messina; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Congenital adrenal hyperplasia (CAH), an autosomal recessive disorder affecting adrenal steroid synthesis, is linked to impaired adrenal synthesis of cortisol and aldosterone. The increased production of androgen precursors in the adrenal cortex during fetal life leads to the virilization of external genitalia in girls with CAH already in utero. LÄS MER

  4. 3. Transport phenomena in quantum wells and wires in presence of disorder and interactions

    Författare :Valeria Vettchinkina; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-dependent density-functional theory; disorder; electron correlation; Lowdimensional semiconducting systems; transport phenomena; Fysicumarkivet F:2012:Vettchinkina;

    Sammanfattning : Present-day electronics employ circuits of smaller and smaller dimensions, and today the length scales are so small that the laws of physics which rule micro-cosmos, quantum mechanics, become directly important. This thesis reports on theoretical work on electron transport in different nanostructures. LÄS MER

  5. 4. Improving Stress Tolerance in Industrial Saccharomyces cerevisiae Strains for Ethanol Production from Lignocellulosic Biomass

    Författare :Valeria Wallace; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; lignocellulose; ethanol; inhibitors; temperature; stress tolerance;

    Sammanfattning : The present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors.

  7. 5. Cold-induced nonshivering thermogenesis : tissue origin, activation, recruitment

    Författare :Valeria Golozoubova; Martin Brand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

    Sammanfattning : Two types of heat production, shivering and nonshivering thermogenesis, are activated in mammals in the cold. In small mammals, nonshivering thermogenesis becomes the main source of heat upon long-term cold exposure. LÄS MER
