  2. 1. Proton pump inhibitors: indications and acid rebound

    Author : Anna Niklasson; Göteborgs universitet; []
    Keywords : Proton pump inhibitors; indications; gastrointestinal symptoms; overuse; chronic obstructive pulmonary disease; acid rebound hypersecretion; gastroesophageal reflux disease;

    Abstract : Proton pump inhibitors (PPIs) are nowadays the therapy of choice in the management of a variety of upper gastrointestinal (GI) conditions particularly gastroesophageal reflux disease (GERD). Previous studies indicate that patients commonly receive PPIs without clear indications. READ MORE

  4. 2. Experimental Investigation of Refrigerant Charge Minimisation of a Small Capacity Heat Pump

    Author : W. Primal D. Fernando; Björn Palm; Alberto Gavallini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat pump; propane; low-charge; Wilson plot method; minichannels; aluminium heat exhangers; single.phase flow; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Abstract : Enormous quantities of heat are available in air, soil, water, exhaust air from buildings, and in waste water of any kind. However these heat sources are use-less for heating purposes since their temperatures are lower than the tempera-ture required for heating. READ MORE

  5. 3. Capacity-controlled Ground Source Heat Pump Systems for Swedish single-family dwellings

    Author : Hatef Madani; Per Lundqvist; Joachim Claesson; Jose Miguel Corberan Salvador; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Pump; Capacity control; ground; ground source; geothermal;

    Abstract : The overall objective of this thesis is to develop a structured method to approach the challenge of better understanding the techniques and potential for capacity control in Ground Source Heat Pump (GSHP) systems used in Swedish single-family dwellings. This thesis aims at development of a generic model of the system that can be used for comparative, descriptive, and predictive analysis of capacity controlled GSHP systems in single-family dwellings.

  6. 4. Design and Analysis of Charge-Pump Bases Frequency Synthsizers

    Author : Tord Johnson; Svante Signell; Mälardalens högskola; []
    Keywords : Datavetenskap;

    Abstract : Most telecommunication systems employ modulation techniques that require the transceiver to be capable of accurately estimating the phase of the transmission signal. The frequency synthesizer is a key element and extensively utilized to synthesize frequencies for such radio-frequency communication systems. READ MORE

  7. 5. Degranulation in macrophages and other leukocytes: regulation by calcium, phosphoinositide 3-kinase, and protein kinase C

    Author : Claes Nauclér; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lysosomal secretion; neutrophil; Clinical biology; proton pump; Klinisk biologi; exocytosis; lysosomal pH;

    Abstract : Macrophages mediate innate immunity through release of cytokines, eicosanoids, reactive oxygen species as well as through phagocytosis and secretion of lysosomal enzymes. Regulation of lysosomal secretion in macrophages differs in several respects from release of specialized granules in other leukocytes. READ MORE
