2. 6. Perspectives of Aerodynamic Drag and Cooling Airflow for Heavy-Duty Trucks - Reconsidering European Total Length Legislation

   Author : Helena Martini; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling airflow; CFD; under-hood design; soft nose; truck-trailer combinations; inlet duct; outlet duct; aerodynamic drag;

   Abstract : Increasing fuel prices and constantly lowered emission legislation forces the vehicle industry to develop new methods for propelling vehicles and to optimize existing technology. Trucks constitute a significant proportion of the transportation system; consequently it is of great importance to ensure as low an impact as possible on the environment. READ MORE

4. 7. Experimental Study of Outlet Guide Vane Heat Transfer and Gas Turbine Internal Cooling

   Author : Chenglong Wang; Värmeöverföring; []
   Keywords : ;

   Abstract : Heat transfer in gas turbine related applications is investigated by steady state liquid crystal thermography (LCT) in this thesis. The work presented includes outlet guide vane heat transfer and gas turbine internal cooling. READ MORE

6. 9. Factors Contributing to Detrusor Overactivity - Obstruction, Hypertrophy and Afferent Nerve Stimulation

   Author : Annette Schröder; Avdelningen för klinisk kemi och farmakologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacological sciences; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; knockout; mice; estrogen receptor; EP1 receptor; prostaglandin; rat; endothelin; detrusor overactivity; rabbit; smooth muscle; bladder outlet obstruction; hypertrophy; pharmacognosy;

   Abstract : The consequences of bladder outlet obstruction (BOO) with respect to detrusor hypertrophy, structural and functional changes, and obstruction-induced detrusor overactivity were investigated in vivo and in vitro utilizing various animal models. Possible pathophysiological pathways and therapeutic approaches were tested by drug treatment and the use of knockout models. READ MORE
