Ekosystemtjänster i det skånska jordbrukslandskapet

Jordbrukslandskapet tillhandahåller ekosystemtjänster som utgör förutsättningen för en uthållig jordbruksproduktion och är till nytta för samhället i stort. Bakom dessa finns ekologiska processer som beror av samspel mellan en mångfald av organismer. Skånes jordbruk har genomgått betydande förändringar som förändrat landskapet och livsmiljön för många av dessa. För att bevara och förvalta ekosyste

Etnisk diskriminering i arbetslivet

Förbud mot könsdiskriminering, enligt vilket en arbetsgivare inte får missgynna en arbetstagare eller en arbetssökande på grund av hans eller hennes kön, har uttryckligen stadgats i Lag om jämställdhet mellan kvinnor och män i arbetslivet. Denna jämställdhetslag är avsedd att befrämja kvinnors och mäns lika rätt i fråga om arbete, arbetsvillkor och utvecklingsmöjligheter i arbetslivet. När det gäl

Nutritional effects of barley products — Mechanisms of action in the intestinal tract

Popular Abstract in English There is a growing prevalence of disorders associated to the metabolic syndrome globally. To reverse this trend lifestyle changes are required. Among dietary factors, dietary fibre that is associated with several health benefits plays an interesting role. Barley is highly unutilized as human food, and it contains high amounts of dietary fibre. The composition of the barBarley is one of the most important crops in the world. Although it is mainly used as the raw material for the production of beer and animal feed, it has recently attracted interest from nutritionists and consumers, due to its high content of dietary fibre, especially β-glucan, and its relation to various positive health effects. The proposed mechanisms behind the health effects are the formation

Resonant states in modulation-doped heterostructures

Popular Abstract in Swedish Denna avhandling handlar om de kvantmekaniska effekter som kan uppstå då man dopar extremt små halvledarstrukturer, och det inflytande detta kan ha på de elektroniska och optiska egenskaperna. Mottot för elektronikindustrin är "mindre, snabbare och billigare". Om man fortsätter göra komponenterna som bygger upp datorer och andra apparater mindre och mindre, hamnar man This thesis deals with the properties of donors placed inside or outside a heterostructure quantum well (QW). The focus of the investigation has been on the formation of resonant states, which are a hybridization of the discrete localized impurity levels and the continuous two-dimensional QW subbands. The impact of such states on the optical properties and the noise spectrum have been investigated

Accelerating signal processing algorithms in digital holography using an FPGA platform

This paper describes the implementation of a custom DSP system to accelerate image processing algorithms used in the field of digital holography. The system, implemented on an FPGA platform, is intended for real-time reconstruction of images captured on a large image sensor. Due to the large amount of processing information, it is not possible to perform a HDL simulation of a complete image recons

Integrated Watershed Management to Save the UNESCO Biosphere Reserve Lake Urmia, Iran

Lake Urmia is a hypersaline lake in northwest Iran. Due to its unique aquatic ecosystem it has been designated as a Biosphere Reserve by UNESCO and a National Park under the 1971 Ramsar Convention. The biodiversity of the lake is determined by its salinity and Artemia urmiana is the dominant invertebrate and also the key element of the lake’s food chain. The lake is relatively shallow and satellit

Iterative time reversal retrofocusing of electromagnetic wave fields

Time reversal is based on recording the wave field by a set of transducers, time reversing the recorded signal, and retransmitting the result. An iterative time reversal algorithm that retrofocuses an electromagnetic wave field to its controllable part is establish. The algorithm utilizes the 'equal fields on the boundary' condition, which can be archived with the wave-guided controllable part of
