  1. 1. Dietary energy density and energy intake in cancer patients

    Författare :Ola Wallengren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cachexia; diagnostic criteria; quality of life; nutritional support; energy intake; energy balance; dietary energy density;

    Sammanfattning : Background & Aims: Cachexia is frequent in advanced cancer and is associated with adverse outcomes; however, definite diagnostic criteria for cachexia are not established. Diet energy density (ED) may affect energy intake (EI) and energy balance. Patient characteristics may also influence such associations. LÄS MER

  3. 2. On Optimization Based Control of Distributed Energy Resources in Power Systems: Electricity Markets and Voltage Regulation Perspectives

    Författare :Pavan Balram; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model predictive control and distribution systems; Electric vehicles; electricity markets; coordinated voltage control; battery energy storage; photovoltaics;

    Sammanfattning : Distributed energy resources are increasingly being integrated into power systems around the world. These resources, typically connected at the distribution system level, are already changing the pattern of power flow from being unidirectional to multidirectional. LÄS MER

  4. 3. Experimental and numerical study of the thermal and hydraulic effect of EMC screens in radio base stations : detailed and compact models

    Författare :Raúl Antón Remírez; Björn Palm; Masud Behnia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sub-rack; perforated plate; air cooling; 90 degrees turn; flow deistribution; CFD; measurement; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : Today’s telecommunication cabinets use Electro Magnetic Compliance (EMC) screens in order to reduce electromagnetic noise that can cause some miss functions in electronic equipment. Many radio base stations (RBSs) use a 90-degree building architecture: the flow inlet is perpendicular to the EMC screen, which creates a complex flow, with a 90-degree air turn, expansions, compressions, perforated plates and PCBs.

  5. 4. Cardiovascular structure and function in obesity. The impact of body composition, sleep apnea and sustained weight loss

    Författare :Dimitris Kardassis; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; weight loss; cardiac function; cardiac structure; inflammation; intima-media thickness; obstructive sleep apnoea;

    Sammanfattning : Background: Obesity is associated with disturbances in cardiovascular structure and function varying along with the degree of fatness, but the mechanisms underlying this co-variation are unclear. Short-term weight loss appears to have favourable effects on the cardiovascular system, but whether such improvements are maintained in the long run is unknown. LÄS MER

  7. 5. Food Packaging for Sustainable Development

    Författare :Helén Williams; Fredrik Wikström; Ole Jørgen Hanssen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Packaging; sustainable development; service perspective; food losses; food waste; consumer interaction; life cycle assessment - LCA; consumer value; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Packaging has been on the environmental agenda for decades. It has been discussed and debated within the society mainly as an environmental problem. Production, distribution and consumption of food and drinks contribute significant to the environmental impact. However, consumers in the EU waste about 20% of the food they buy. LÄS MER
