1. 1. Oxygen-dependent regulation of key components in microbial chlorate respiration

   Författare :Miriam Hellberg Lindqvist; Thomas Nilsson; Stefan Nordlund; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic respiration; Gene expression; Chlorate; Chlorate reductase; Chlorite dismutase; Kemi; Chemistry;

   Sammanfattning : Contamination of perchlorate and chlorate in nature is primarily the result of various industrial processes. The microbial respiration of these oxyanions of chlorine plays a major role in reducing the society’s impact on the environment. LÄS MER

3. 2. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases

   Författare :Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; Biochemistry; biokemi;

   Sammanfattning : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

4. 3. Cardiovascular and respiratory effects of apnea in humans

   Författare :Johan Andersson; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

   Sammanfattning : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. LÄS MER

5. 4. Double Poling Incross-Country Skiing : Biomechanical and Physiological Analysis of Sitting and Standing Positions

   Författare :Marie Lund Ohlsson; Marko Laaksonen; Jonas Danvind; L. Joakim Holmberg; Anders Eriksson; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood lactate concentration; cross-country sit-skiing; impairment; internal kinetics; inverse dynamics simulations; joint reaction forces; kinematics; metabolic rate; musculoskeletal modelling; musculoskeletal efficiency; nordic skiing; oxygen uptake; para-skiing; respiration; skiing efficiency.;

   Sammanfattning : Double poling (DP) is a sub-technique in cross-country skiing that has increased in interest over the last decades, e.g. athletes in cross-country skiing have increased their utilisation of double poling during competitions. LÄS MER

7. 5. Quality and function of anaerobic digestion residues

   Författare :Kajsa Risberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The growing number of biogas plants in Europe has resulted in increased production of nutrient-rich digestate, which has potential as fertiliser on arable land. Many different organic materials can be degraded in the anaerobic digestion process, with most macronutrients and micronutrients retained in the digestate. LÄS MER
