1. 1. Where Gendered Spaces Bend : The Rubber Phenomenon in Northern Laos

   Författare :Anna-Klara Lindeborg; Aida Aragao - Lagergren; Susanne Stenbacka; Jonathan Rigg; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Laos; LuangNamtha; rubber; gender; HatNyao; everyday life; bend; transitions; paradoxical spaces; intersectionality; ethnography; Hmong; phenomenon; gender contract; intersectionality; border-region; division of labour; China; Social and Economic Geography; Kulturgeografi; Geography;

   Sammanfattning : This thesis seeks to understand and explain gendered everyday life in the village of HatNyao in Northwestern Laos, specifically in relation to rubber cultivation, by using an ethnographic approach and methods. The ‘rubber boom’ is changing the landscape of Northern Laos, and in the process is reshaping gendered everyday life. LÄS MER

3. 2. Experimental study of turbulent flows through pipe bends

   Författare :Athanasia Kalpakli; P. Henrik Alfredsson; Ramis Örlü; Christoph Brücker; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent flow; swirl; pulsation; pipe bend; hot-wire anemometry; cold-wire anemometry; laser Doppler velocimetry; stereoscopic particle image velocimetry.;

   Sammanfattning : This thesis deals with turbulent flows in 90 degree curved pipes of circular cross-section. The flow cases investigated experimentally are turbulent flow with and without an additional motion, swirling or pulsating, superposed on the primary flow. LÄS MER

4. 3. Heat and Mass Transfer Effects in a U-Bend in Pneumatic Drying

   Författare :Muslikhin Hidayat; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Pneumatic conveying drying is a widely used process in many engineering applications. Due to the high velocity of the drying medium and the limited conveying distance, the drying times of theses dryers are typically short, in the order of seconds. LÄS MER

5. 4. An Experimental and Numerical Study of Heat Transfer and Pressure Drop on the Bend Surface of a U-duct

   Författare :Tareq Salameh; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This work concerns experimental and numerical studies of pressure drop and heat transfer for turbulent flow inside a U-duct and in particular the bend part. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. LÄS MER
