3. 7. Impact of the upper gut on body fluid regulation and blood pressure in man - potential involvement of a locally expressed renin-angiotensin system

   Författare :Peter Hallersund; Göteborgs universitet; []
   Nyckelord :angiotensin; stomach; duodenum; sodium; salt; diuresis; appetite; gastric bypass; blood pressure;

   Sammanfattning : This thesis explores the role of the upper gut in the regulation of diuresis and blood pressure control in relation to the novel finding of a mucosa-located renin-angiotensin system (RAS). RAS is a regulatory super-system vital for body fluid homeostasis and blood pressure control. LÄS MER

4. 8. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning

   Författare :Mattias Nilsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elevated temperatures; Electroviscous friction; Energy; pH; Economics; Nanofiltration; Pre-treatment; Salt; Swelling; Membrane performance; Cleaning; Temperature;

   Sammanfattning : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. LÄS MER

5. 9. Characterization of Raw Materials for Salt Extraction from Lake Katwe, Uganda

   Författare :Hillary Kasedde; Stefan Jonsson; Baohua Zhu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; characterization; PHREEQC;

   Sammanfattning : Uganda is well endowed with economic quantities of salt evident in the interstitial brines and evaporite deposits of Lake Katwe, a closed saline lake located in the western branch of the great East African rift valley. Currently, rudimentally methods of salt mining based on solar evaporation of brine continue to be used for salt extraction at the lake. LÄS MER

7. 10. Towards the Improvement of Salt Extraction from Lake Katwe Raw Materials in Uganda

   Författare :Hillary Kasedde; Pär Jönsson; Anders Tilliander; Eric Forssberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; saltpan; characterization; evaporation - crystallization; solubility; Pitzer ’s ion - interaction model; PHREEQC software; dissolution kinetics; Avrami model.;

   Sammanfattning : Uganda is well endowed with economic quantities of mineral salts present in the interstitial brines and evaporite deposits of Lake Katwe, a closed (endorheic) saline lake located in the western branch of the great East African rift valley. Currently, rudimentally and artisanal methods continue to be used for salt extraction from the lake raw materials. LÄS MER
