Hydrological Modelling, Topographical Influence and Yield Mapping in Precision Agriculture

The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. The yield was recorded with a new optical sensor, which uses a digital camera to detect objects and records th

Bone turnover markers and prediction of bone loss in elderly women

Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. Biochemical markers of bone turnover (BTMs) have shown some degree of fracture predictability. There is also a correlation b

Mitochondrial and chromosomal genomics in type 2 diabetes

Understanding the mechanisms of complex polygenic diseases like type 2 diabetes (T2D) is as complex as their nature. Cellular processes involved in glucose homeostasis need high and reliable energy supply. Mitochondria are the major energy producers in mammalian cells. Since majority of the mitochondrial genes are encoded by the nuclear genome, a tightly regulated and coordinated nuclear-mitochond

A stranger in my homeland. The politics of belonging among young people with Kurdish backgrounds in Sweden

This dissertation examines how young people with Kurdish backgrounds form their identity in Sweden with regards to processes of inclusion and exclusion. It also sheds light on the ways these young people deal with ethnic discrimination and racism. Further, the study outlines the importance of these social processes for the discipline of social work and the ways social workers can work with disadva

Calcium deposition and expression of bone modelling markers in the tympanic membrane following acute otitis media

Background and objectives In accordance with clinical findings, myringoscterosis develops after otitis media (OM) and paracentesis in an experimental setting. The pathogenesis of this phenomenon of calcification is poorly understood. As the calcification process and the sclerotic plaques of the drum mimics features of bone tissue, this study explores tympanic membrane calcium deposition in associa

Arsenic mobilisation in a new well field for drinking water production along the Red River, Nam Du, Hanoi

Arsenic enrichment of groundwater in the Red River (Song Hong) delta in Vietnam was discovered in 1998.

Element cycling in forest soils -modelling the effects of a changing environment

Element cycling and nutrient supply in forest ecosystems are of vital importance for short-term productivity and for longer-term land management in terms of nutrient leaching and CO2 fixation. This thesis includes a series of studies with the objective of modelling some aspects of the effect of acidification and climate change on element cycling and nutrient supply in forest soil. A reconstructio

Groundwater occurrence and risk of pollution in a mountain watershed of Nicaragua

Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. The aim of this work was to characterise the hydrogeological conditions in the basin with emphasis on understanding the possible co

Enzymatic hydrolysis coupled to hot water extraction for determination of flavonoids in plants

Popular Abstract in Swedish I Sverige produceras dagligen flera ton biprodukter avfall inom jordbruks-, livsmedels- och skogsindustrierna. Detta avfall förbränns, komposteras och går till biogasproduktion samt i vissa fall till djurfoder. Intressanta avfallsgrupper ur ett svenskt perspektiv är lök- morots-, och potatis avfall från jordbruk- och livsmedelsindustrin och bark från skogsindustrin. DesThe word sustainability is more and more frequently used within the field of chemistry and in many other fields. Green or sustainable chemistry was introduced during the 90 ́s as a field of chemistry where the environmental and health impacts of processes and products are evaluated and improved. Within analytical chemistry the awareness of sustainability has also increased, which has resulted in o

Antibody Evolution and Repertoire Development

Popular Abstract in Swedish Antikroppar är viktiga beståndsdelar av det naturliga immunförsvaret som skyddar oss mot smittämnen, såsom bakterier och virus. Utvecklingen av olika genetiska och biokemiska teknologier har dessutom möjliggjort användningen av antikroppar för en mängd ändmål, bl a för diagnostik och behandling av infektionssjukdomar och cancer. I denna avhandling, som bygger på fem vetAntibodies are key players of the immune system in higher vertebrates, which provide a defense against potentially lethal threats from the environment. Besides their importance in the immune defense, antibodies have a great potential as reagents in biological chemistry and diagnostics, and as therapeutic agents against both infectious diseases and cancer. Despite tremendous advances in all fields
