  1. 1. Security in Physical Distribution Networks - A Survey Study of Swedish Transport Operators

    Författare :Luca Urciuoli; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antagonistic threats.; supply chain security; cargo security; physical distribution security; transportation security; cargo theft; Quantitative Risk Assessment;

    Sammanfattning : The objective of this study is to understand what factors influence the security of physical distribution networks. Thereafter it aims to bring to light what security measures exist today to enhance security and finally how to determine the profitability of security investments. LÄS MER

  3. 2. Studies on periodontitis and analyses of individuals at risk for periodontal diseases

    Författare :Henrik Jansson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotics; diabetes mellitus; genotype; periodontal disease; risk factor;

    Sammanfattning : Parodontit är en infektionssjukdom som orsakas av munhålans normala bakterieflora samt faktorer i infektionsförsvaret. Det inflammatoriska svaret fungerar som ett skydd för värden men är samtidigt vävnadsnedbrytande. Detta är anledningen till förlust av tandens stödjevävnader. LÄS MER

  4. 3. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators

    Författare :Eskil Johnsson; Institutionen för laboratoriemedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antigenic variation; factor H; C4b-binding protein; Fc-receptor; IgA; Streptococcus pyogenes; M protein; mykologi; virologi; bakteriologi; Mikrobiologi; virology; mycology; bacteriology;

    Sammanfattning : The human pathogenic bacterium Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. LÄS MER

  5. 4. Effect of Wood Constituents Oxidation of Unsaturated Fatty Acids

    Författare :Alireza Salehi Movahed; Mats K.G. Johansson; Mats Johnssson; Karin Jacobsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wood constituents; oil; oxidation; unstatured fatty acids; lignin; model lignin compounds; Polymer chemistry; Polymerkemi;

    Sammanfattning : This work presents the mechanisms of free radicals in a model system between fatty acids oxidation process and wood components. The aim is to create a better understanding of new environmentally friendly materials for exterior wood protection. LÄS MER

  7. 5. Grazing and the geographical range of seaweeds : The introduced Fucus evanescens and the newly described Fucus radicans

    Författare :Helena Forslund; Lena Kautsky; Ove Eriksson; Veijo Jormalainen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-indigenous species; phlorotannin; herbivore defense; ; Biology; Biologi; Marine ecology; Marin ekologi; Plant Ecology; växtekologi;

    Sammanfattning : Along the coast of temperate oceans brown algae of the genus Fucus form dense stands on rocky shores and are keystone species of the coastal ecosystem. These large seaweeds are perennial and function as substrate for many sessile marine organisms, provide shelter for fauna and juvenile fish, and are food source. A number of abiotic (e.g. LÄS MER
