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

    Author : Karin Edvardsson; Björn Birgisson; Andrew Dawson; KTH; []
    Keywords : 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;

    Abstract : Approximately 75 percent (300 000 km) of the total Swedish road network and 20 percent(20 000 km) of the national road network consists of gravel roads. One of the most significantproblems associated with gravel roads is traffic-generated dust emission, which contributes tothe deterioration of the road surface and acts as a major source of particulate matter releasedinto the atmosphere, thereby involving public economics, road safety, human health, andenvironmental quality.

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

    Author : Karin Oscarsson; Högskolan Dalarna; []
    Keywords : 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.; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : 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. READ MORE

  3. 3. Studies on the Role of UDP-Glucose Dehydrogenase in Polysaccharide Biosynthesis

    Author : Elisabet Roman; Marion Kusche-Gullberg; Hakon Leffler; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; UDP-glucose dehydrogenase; polysaccharide biosynthesis; glycosaminoglycan; A. thaliana; E. coli K5; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Abstract : Polysaccharides are found in all forms of life and serve diverse purposes. They are enzymatically synthesised from activated monosaccharide precursors, nucleotide sugars. One such nucleotide sugar is UDP-glucuronic acid, which is formed from UDP-glucose by the UDP-glucose dehydrogenase (UGDH) enzyme. READ MORE

  4. 4. Rhizoctonia solani and sugar beet responses : genomic and molecular analysis

    Author : Louise Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The soil-borne basidiomycete Rhizoctonia solani (strain AG2-2) incite root rot disease in sugar beet (Beta vulgaris). The overall objective of this thesis work was to enhance the genomic knowledge on this pathogen and induced responses in the host to promote breeding of better performing cultivars. The AG2-2IIIB R.

  5. 5. Structural and functional investigation of underexplored carbohydrate-active enzyme families

    Author : Andrea Seveso; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbohydrate-active enzymes; lytic polysaccharide monooxygenase; plant biomass degradation; copper radical oxidases; carbohydrate esterase; protein structure determination; protein structure prediction;

    Abstract : The known consequences of the current fossil-based economy require a transition towards a bio-based economy. Development of biorefineries in which plant biomass can be utilized as a renewable source of energy and building blocks to produce both commodities and high-value products, is a key step in this transition.
