1. 6. Lipases at interfaces

   Författare :Pedro Reis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrolysis.; fat; microenvironment; depletion; surfactant; interface; Lipase; modulation; digestion; synthesis;

   Sammanfattning : Lipases are acyl hydrolases that play a key role in fat digestion by cleaving long-chain triglycerides into polar lipids. Due to an opposite polarity between the enzyme (is hydrophilic) and their substrates (are lipophilic), the lipase reaction occurs at the interface between the aqueous and the oil phases. LÄS MER

3. 7. Future stratospheric ozone depletion will affect a subarctic dwarf shrub ecosystem

   Författare :Ulf Johanson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vaccinium; UVB; subarctic; shoot growth; ozone depletion; leaf thickness; irradiation system; heath ecosystem; Empetrum; dwarf shrubs; Calamagrostis; decomposition; Physiological biophysics; Växtfysiologi;

   Sammanfattning : The stratospheric ozone depletion and the concomitant increase in ultraviolet-B (UV-B, 280-320 nm) radiation is of global concern due to the effects of UV-B on living organisms. To investigate the effects of increased levels of UV-B, a field irradiation system was established at a subarctic dwarf shrub heath in Northern Sweden (68 °N). LÄS MER

4. 8. Can the ego be depleted? : Attempts to replicate the ego depletion effect and integrate its explanations

   Författare :Junhua Dang; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Self-control; Ego depletion; Pre-registration; Meta-analyses; Goal maintenance; Competition resolution;

   Sammanfattning : Although self-control is so important that no one from any corner of the world would dispute, it is often difficult and vulnerable. Continuous exertion is one of the most influential factors that are detrimental to self-control, which leads to a state called “ego depletion”. LÄS MER

5. 9. A Study of Polar Ozone Depletion in the Lower Stratosphere. -Dynamical assimilation of O3 and N2O data from Odin/SMR and ENVISAT/MIPAS

   Författare :JOHN RÖSEVALL; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SMR; O3; stratosphere; Odin; data assimilation; transport modelling; atmosphere; NO2; ozone depletion; MIPAS;

   Sammanfattning : For more than 20 years, a hole in the ozone layer has formed each spring over Antarctica when sunlight returns to the polar region. Similar albeit far less extensive ozone destruction has also been observed in the Arctic polar vortex after colder than average winters. LÄS MER

7. 10. Nutritional Depletion in Chronic Obstructive Pulmonary Disease (COPD) : Effect on Morbidity, Mortality and Physical Capacity

   Författare :Runa Hallin; Christer Janson; Frode Slinde; Magnus Sköld; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic obstructive pulmonary disease; nutrition; pulmonary rehabilitation; physical capasity; systemic inflammation; Lung diseases; Lungsjukdomar;

   Sammanfattning : The overall aim of this work was to examine the effects of depleted nutritional status on some aspects of Chronic Obstructive Pulmonary Disease (COPD).Morbidity. In paper І, we found that energy intake was lower than the calculated energy demand for all patients. LÄS MER
