1. 16. Exercise in patients with chronic heart failure. With emphasis on peripheral muscle training, hydrotherapy and type 2 diabetes mellitus

   Författare :Åsa Cider; Göteborgs universitet; []
   Nyckelord :Exercise tolerance; Ejection fraction; Metabolic function; Muscle function; Oxygen uptake; Physical therapy techniques; Quality of life; Rehabilitation; Stroke volume; Water immersion;

   Sammanfattning : Chronic heart failure (CHF) is not uncommon in developed countries with a growing ageing population. CHF is a chronic syndrome, which markedly impact negatively on the patient s life situation. Considerable impaired physical function and reduced health related quality of life is often present.

3. 17. Ice out of Fire : Ice and cloud condensation nucleation of aerosol particles emitted from controlled soot generation and combustion of renewable fuels

   Författare :John Falk; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soot; BC; Immersion freezing; IN; INP; CCN; SPIN; CCNC; MiniCAST; Cold Stage; Cook Stove;

   Sammanfattning : Aerosol particles, small solid or liquid particles suspended in a gas, are found everywhere in the atmosphere. Air pollution from such particles, mainly soot from combustion-derived activity is a leading cause of premature deaths in the world and have a large effect on the climate. LÄS MER

4. 18. Corrosion testing of heat exchanger tubing

   Författare :Ulf Kivisäkk; KTH; []
   Nyckelord :corrosion testing; heat exchanger; stainless steels; general corrosion; immersion testing; activation; stress corrosion cracking; constant load; u-bends; relaxation; dewpoint corrosion;

   Sammanfattning : Heat exchanger tubes are commonly made from stainless steel.In a heat exchanger both the process fluid and the cooling orheating media can be corrosive. It is therefore important to beable to select materials that do not suffer from corrosion.Current methods in this area, however, suffer from limitationsand shortcomings. LÄS MER

5. 19. Autonomic cardiac control in long QT syndrome : clinical studies of arrhythmogenic triggers

   Författare :Anna Lundström; Annika Rydberg; Urban Wiklund; Håkan Eliasson; Jacob Tfelt-Hansen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; pediatrics; exercise; Holter; water immersion; arrhythmia; clinical physiology; ECG; heart rate variability; heart rate response; cardiovascular disease; hjärt- och kärlforskning; kardiologi; Cardiology; pediatrik; Pediatrics;

   Sammanfattning : Background: Long QT syndrome (LQTS) is an inherited cardiac disease characterized by prolonged cardiac repolarization and an increased risk for life-threatening arrhythmias. These arrhythmias are typically triggered by adrenergic stimuli, such as physical activity and intense emotions, implicating that the sympathetic part of the autonomic nervous system (ANS) is involved in arrhythmogenesis.

7. 20. 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
