  2. 1. Heat exposure and health outcomes in Costa Rican sugarcane harvesters

    Author : Jennifer Crowe; Maria Nilsson; Tord Kjellström; Catharina Wesseling; Linda Forst; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Agricultural worker; Central America; Chronic kidney disease; Climate change; Dehydration; Heat; Heat illness; Heat stress; Sugarcane; Urinalysis; Worker health; folkhälsa; Public health; Epidemiology; epidemiologi;

    Abstract : Background The remarkably efficient mechanisms of the human body to maintain its core temperature of 37°C can be inadequate when harsh climatic conditions and excessive muscle movement lead to heat stress, dehydration and potential heat illness, ranging from minor symptoms such as fatigue to a potentially fatal heat stroke. Agricultural workers in the tropics are at high risk, which is expected to increase with climate change. READ MORE

  4. 2. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System

    Author : Habib Aghaali; Hans-Erik Ångström; Carlos Guardiola; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; heat transfer; heat loss; exhaust heat utilisation; waste heat recovery; turbocompound; divided exhaust period; internal combustion engine; gas exchange; pumping loss; variable valve timing; WHR; DEP; Turbo; värmeöverföring; värmeförluster; avgasvärme utnyttjande; förluster vid värmeåtervinning; turbocompound; delad avgasperiod; förbränningsmotor; gasväxling; pumpningsförlust; variabla ventiltider; WHR; DEP; Vehicle and Maritime Engineering; Farkostteknik; Energy Technology; Energiteknik;

    Abstract : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. READ MORE

  5. 3. Outdoor heat in urban areas - Model development and applications

    Author : Nils Wallenberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mean radiant temperature; Urban Climate; SOLWEIG; Outdoor Thermal Comfort;

    Abstract : Heat waves and high outdoor air temperature can lead to heat stress with negative implications for human health and wellbeing such as heat stroke, heat cramps, dehydration and in extreme cases death. The urban population is at higher risk of such outcomes because of the generally warmer urban climate. READ MORE

  6. 4. Estimation of the In-Cylinder Air/Fuel Ratio of an Internal Combustion Engine by the Use of Pressure Sensors

    Author : Per Tunestål; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; hydraulik; Maskinteknik; nonlinear; cylinder pressure; engine; least-squares; Mechanical engineering; estimation; hydraulics; vibration and acoustic engineering; vacuum technology; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem;

    Abstract : This thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. READ MORE

  7. 5. On the function endogenous pain controlling systems in healthy subjects and patients with peripheral or central neuropathic pain

    Author : Birgitta Tuveson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Painful peripheral neuropathy; Central post-stroke pain; Dynamic mechanical allodynia; Endogenous pain modulation; Heterotopic noxious conditioning stimulation; Quantitative sensory testing; Ondansetron;

    Abstract : Introduction and aim: Activity in the nociceptive system is modulated by descending inhibitory and facilitatory supraspinal endogenous control. Altered balance between inhibition and facilitation has been suggested to at least partly explain the maintenance of some persistent pain conditions. READ MORE
