I detta kapitel studeras något så oglamoröst som hur människor hanterar sitt hushållsavfall i vardagliga situationer, de problem växande sopberg leder till och hur samlade nationella och internationella processer leder till politiska beslut, målsättningar och åtgärder som för med sig att aktörer på skilda nivåer ända ner till den enskilda hushållsmedlemmen måste ändra sitt beteende och delta i sam

During a machining operation the workpiece material at some point has to split up into two separate material flows forming the chip and machined surface respectively. In the boundary zone between these two different flows of material it is possible to distinguish a stagnation point. This stagnation point is closely related to the minimum chip thickness h1min. The size of h1min is of great interest

Popular Abstract in Swedish När främmande fettlösliga ämnen som miljögifter (ex. PCB och dioxin) hamnar inuti kroppen bearbetas de ofta av det så kallade biotransformations-systemet. När inte levern och njurarna direkt kan utsöndra de främmande molekylerna får enzymer ändra de oönskade ämnenas kemiska sammansättning. Detta görs genom att ändra molekylernas kemiska egenskaper så att de blir vattenlIn vertebrates, studies of the aryl hydrocarbon receptor (AhR) have been of particular interest due to its direct involvement in the toxic effects exerted by several environmental pollutants, such as PCB and dioxin. After binding to the toxic molecule, this receptor initiates transcription of several genes that are part of the biotransformation battery but most notably the cytochrome P450 (CYP) ge

Popular Abstract in Swedish Bakgrunnen for den foreliggende avhandling er et ønske om å utnytte moderne tredimensjonell bildeanalyse for å forbedre undersøkelse og tolkning av synsnervehodets (papillens) form og størrelse (topografi). Synsnervehodet representerer den delen av synsnerven som trer inn i bakre del av øyet gjennom senehinnen (sklera). Den normale synsnerve har ca 1.2 millioner nervetrEvaluation of the optic nerve head topography is one of the most important methods to diagnose and monitor patients with glaucoma. Until recently, optic nerve head topography has most often been judged by either ophthalmoscopy or from optic disc photographs. These methods are subjective and examiners do not have access to absolute measurements of the optic disc size and cup depth. The result of su

There is increasing evidence that fermentation in the large intestine is important for health, and that health-promoting effects are mediated by fermentation products such as butyric and propionic acid. As the formation of carboxylic acids (CAs) from various carbohydrates reaching the colon has been shown to vary, it is of great interest to identify food factors that could be of importance to this
