Popular Abstract in Swedish Mekanisk ventilation kan medföra "ventilationsinducerad lungskada" (VILI), som kan öka sjuklighet och dödlighet i samband med akut lungskada (ALI). Flera ventilationssätt har föreslagits för att undvika VILI, men inte slutgiltigt utvärderats. En princip är att öka alveolär ventilation och CO2-elimination genom att minska ventilationen av de skadliga rummet, dead space. Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. by aspiration of dead space gas (ASPIDS). ASPIDS implies that gas rich in CO2 during expiration is aspirated through a separate c

Popular Abstract in Swedish Den största källan till läkemedelsrester i vattenmiljön är utgående renat avloppsvatten från våra kommunala reningsverk. Läkemedel är utvecklade för att ha olika typer av biologiska effekter. Vilka dessa är i människan är relativt välkänt, medan effekterna på vattenlevande organismer och andra djur till stor del är okända. Detta i kombination med deras resistens mot de The discharge of effluents from wastewater treatment plants (WWTPs) is considered to be the major source of residual pharmaceuticals frequently found in aquatic environments. The complex nature of such compounds tends to make conventional biological treatments aimed at their removal ineffective. The present thesis concerns the removal of 62 different active pharmaceutical ingredients commonly dete

Environmental aspects have during the last years made electric vehicles an interesting competitor to the present internal combustion engine driven vehicles. For a broad introduction of pure electric vehicles, a battery charging infrastructure is deemed necessary. However, to build and maintain such an infrastructure is costly. Active power line conditioning capabilities could be included in the ba

Students completing a Swedish Master’s degree in engineering should have knowledge and skills to independently solve engineering issues. This autonomy should be developed and demonstrated within the M.Sc. project course. But, how can supervisors encourage independence? We have explored this in a case study through semi-structured interviews with students, supervisors and examiners of two M.Sc. pro

Traditionally, control loops are closed using periodic sensing and actuation. When communication resources are scarce, however, much may be gained from transmitting only when something important has happened in the loop. This paper presents a simple model of the interference between event-based control loops caused by sharing a common medium, based on the coupled dynamics of a Markov chain represe

Popular Abstract in Swedish Kostfiber kallas de kolhydrater från växtriket som inte bryts ner under matsmältningen och därför når tjocktarmen i stort sett opåverkade. Kostfiber finns till exempel i våra fyra sädesslag, havre, råg, korn och vete, vilka alla är cerealier. Framför allt är det de yttre delarna av cerealiekärnorna, klidelen, som innehåller mycket kostfiber. I cerealier är de vanligasteIt is well known that dietary fibre is good for the health. Cereals, and in particular the outer parts of the cereal kernels, are rich in dietary fibre. Rye bran, wheat bran, oat bran and barley fibre have been investigated regarding their suitability as additives in low-fat meat products. Two types of meat products, frankfurter-type sausages and meatballs have been evaluated in this thesis. In th
