  1. 1. Evaluation of Dust Suppressants for Gravel Roads: Methods Development and Efficiency Studies

    Detta är en avhandling från Stockholm : KTH

    Författare :Karin Edvardsson; Karin Oscarsson; KTH.; Högskolan Dalarna.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road; dust; particulate matter; PM10; horizontal dust diffusion; deteriorations; maintenance; dust control; dust suppressants; efficiency; application rate; leaching; residual concentration; seasonal variations; salt solution; solid salt; calcium chloride; magnesium chloride; lignosulphonate; polysaccharide sugar ; bitumen emulsion; rape oil; starch; surfactant; mesa; clay; fine material content; Komplexa system - mikrodataanalys; fine material content.;

    Sammanfattning : Application of the proper dust suppressant to a gravel road ensures road safety and riding comfort as well as creating a cleaner and healthier environment for residents in buildings adjacent to the road. It also reduces the need and cost for vehicle repair, road maintenance activities, and aggregate supplementation. LÄS MER

  2. 2. The interplay of ions in the stimulation of the pancreatic -cell

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; diabetes; pancreatic β-cells; cytoplasmic calcium; oscillations; glucose; tetrodotoxin; tolbutamide; veratridine; tetraethylammonium; quinine; cesium; H2DIDS; furosemide; transients; microfluorometry; fura-2; MQAE; calcium channels; potassium channels; sodium channels; chloride channels; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Glucose stimulation of insulin release is mediated by depolarisation of the pancreatic β-cells with accompanying entry of Ca2+ through voltage-dependent channels. An important feature of the glucose-induced depolarisation is its rhythmicity causing oscillations of the cytoplasmic Ca2+ concentration ([Ca2+]i), which trigger pulsatile release of insulin.

    Sammanfattning : Aqueous solutions were studied using photoelectron and Auger spectroscopy, based on synchrotron radiation and a liquid micro-jet setup.By varying the photon energy in photoelectron spectra, we depth profiled an aqueous tetrabutylammonium iodide (TBAI) solution. LÄS MER

  4. 4. Chloride Channels and Brown Fat Cells

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Victor Sabanov; Stockholms universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chloride channel; BAPTA; EGTA; Ca; NATURAL SCIENCES Biology Organism biology Animal physiology; NATURVETENSKAP Biologi Organismbiologi Zoofysiologi;

    Sammanfattning : Chloride ion channels are macromolecular pores providing for passage of chloride ions (and certain other inorganic and organic anions) through the cell membrane, down their electrochemical gradients. Chloride channels are differentially expressed in various cells, to best suit specific cellular activities. LÄS MER

  5. 5. Inorganic ions in wood chips- Leaching prior to Kraft pulping and effect of calcium on Kraft delignification

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Anna Saltberg; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; calcium; Scandinavian softwood; Keywords: Kraft pulping; potassium; birch; eucalyptus; aspen; acidic leaching; oxalate.;

    Sammanfattning : Wood is the main source of Non-Process Elements (NPEs), such as, calcium, potassium, manganese and chloride in Kraft pulp mills. Due to the recirculation of cooking chemicals and water, process disturbances related to the accumulation of NPEs in the process streams are inevitable. LÄS MER
