  1. 16. Factors Associated with Motorcylists' Safety at Access Points along Primary Roads in Malaysia

    Författare :Marizwan Manan; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; access point; primary road; motorcyclists’ behavior; Safety Performance function; Motorcycle accident fatality;

    Sammanfattning : More than 50% of road accident fatality victims in Malaysia are motorcyclists, numbering more than 4,000 fatalities per year. The aim of this thesis is to investigate motorcyclists’ road safety problems in general in Malaysia, and narrow down the focus to the most salient road infrastructure related risk factors. LÄS MER

  3. 17. Epidemiological studies in Malaysia and Sweden on associations between smoking, silica exposure and the risk of developing rheumatoid arthritis

    Författare :Abqariyah Yahya; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Rheumatoid arthritis (RA) is a chronic, inflammatory disease, frequently associated with joint destruction. Knowledge regarding the aetiology of RA is mainly generated on Caucasian populations. Less is known about RA in other populations with different genetic backgrounds and lifestyles. LÄS MER

  4. 18. In the wake of the Green Revolution : Environmental and socioeconomic consequences of intensive rice agriculture - The Problems of weeds in Muda, Malaysia

    Författare :Magnus Jirström; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; intensification; land degradation; rice agriculture; IPM integrated pest management ; Social geography; sustainable agriculture; Green Revolution; Socialgeografi;

    Sammanfattning : The agricultural intensification strategies represented by the Green Revolution have since the mid-1960s had a very positive impact on food-grain production in Asia. Presently, however, a post-Green Revolution phase of declining growth in output and productivity is experienced in many of the areas where intensification took place. LÄS MER

  5. 19. Role of Melatonin, Neuropeptide S and Short Chain Fatty Acids in Regulation of Duodenal Mucosal Barrier Function and Motility

    Författare :Wan Salman Wan Saudi; Markus Sjöblom; Olof Nylander; Mark Berner-Hansen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; rat; in vivo; duodenum; enteric nervous system; paralytic ileus; parecoxib; bicarbonate secretion; motility; ethanol; HCl; melatonin; neuropeptide S; short chain fatty acids; chemosensing; Physiology; Fysiologi;

    Sammanfattning : The duodenal epithelium is regularly exposed to HCl, digestive enzymes, bacteria and toxins, and sometimes also to ethanol and drugs. The imbalance of aggressive factors in the intestinal lumen and mucosal barrier function increases the risk of tissue injury and inflammation. LÄS MER

  7. 20. Interaction of Lightning Flashes with Wireless Communication Networks : Special Attention to Narrow Bipolar Pulses

    Författare :Mohd Riduan Ahmad; Vernon Cooray; Mahbubur Rahman; Rajeev Thottappillil; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Latitude; Lightning; Narrow bipolar pulse; Wireless network.; Engineering Science with specialization in Atmospheric Discharges; Teknisk fysik med inriktning mot atmosfäriska urladdningar;

    Sammanfattning : In this thesis, the features of electric field signatures of narrow bipolar pulses (NBPs) generated by cloud flashes are investigated and their effects on wireless communication systems are studied. A handful amount of NBPs (14.5%) have been observed to occur as part of cloud-to-ground flashes in South Malaysia. LÄS MER
