  2. 1. Advancing the Implementation of Protective Measures for Drinking Water Sources in Sweden

    Author : Nadine Gärtner; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; water protection; mitigation measures; spatial planning; groundwater; surface water; drinking water; risk assessment;

    Abstract : The world’s drinking water sources are under growing pressure due to human activities, including infrastructure projects, agriculture, climate change, and the ever-increasing need for freshwater. Although there is a strong call to protect our source waters instead of increasing treatment efficiency at the drinking water treatment plant, the extent of protection measures is often hotly debated.

  4. 2. Odour guided predation on acorns by small rodents during direct seeding

    Author : Mattias Engman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Costs related to planting of seedlings and plant material is a major economic obstacle that may impede successful large-scale forest restoration. One way to reduce this cost is to use direct seeding instead of planting. Nut-bearing trees such as oaks have seeds with large nutrient storage that results in competitive seedlings. READ MORE

  5. 3. Active oxygen involvement in developmental processes in Populus : with emphasis on HipI-superoxide dismutase

    Author : Vaibhav Srivastava; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : In plants, oxidative stress is result of disruption of the cellular redox metabolism and is caused by a variety of stress conditions (abiotic and/or biotic). This leads to the induction of several mechanisms that protect against disruption of the redox balance, as well as mechanisms to assist in recovery from toxicity/damage caused by increased cellular levels of reactive oxygen species (ROS).

  6. 4. Microbial production of 3-hydroxypropionic acid and poly(3-hydroxypropionate): Investigation of Lactobacillus reuteri propanediol utilization pathway enzymes

    Author : Ramin Sabet Azad; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platform chemicals; biopolymers; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; glycerol; poly 3-hydroxypropionate ; polyhydroxyalkanoates; Escherichia coli; Lactobacillus reuteri; propanediol utilization pathway; propionaldehyde dehydrogenase; biotransformation; cofactor regeneration; NADH oxidase;

    Abstract : Concerns regarding environmental issues such as greenhouse gas emissions and climate change have led to a shift within the research community and chemical and energy industry sectors for finding sustainable routes for producing fuels and chemicals from renewable resources, thereby minimizing our dependence on petroleum. The C3-chemical 3-hydroxypropionic acid has been identifed as a top candidate for the biobased chemical industry. READ MORE
