Optical and Structural Properties of CuxS Quantum Dots Concerning H2O/Ethanol Solvent Ratio

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?

Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.

Deltid och kön: En undersökning av deltidsarbetets utveckling under åren 1987-2005

This paper aims at assessing the relationship between female and male part-time employment and the business cycle in Sweden during the years 1987?2005 using quarterly time-series data and two alternative indicators of the business cycle. It further aims at determining whether the share of women working part-time has changed over time. Key results include that the relationship between the business cycle and female part-time employment is found to be significant and countercyclical. No significant effect is however found for men.

Ekonomi eller politiska beslut : Vad styr fristående gymnasieskolors lokalisering?

In the beginning of the 1990s the responsibility for the schools shifted from the government to the local authorities. This started an era with a freedom of choice for students where they themselves could choose which school to go to. The new system also opened up the possibility for independent private schools to exist side by side with local authority held schools. The overall aim of this study is to determine the factors that affect the location of these independent schools and the geographical pattern these independent schools create. The study in this paper is based on materials from statistics and interviews.

Inverkan av SPC på induktion av protein AF och produktionsresultat hos slaktkyckling

This study was a degree in Master of Science in agriculture with specialization in animal science for the Department of animal nutrition and management at SLU. The subject was created by AS-Faktor, a small company for science and development within the company Lantmännen AB. It was a test of the effect of SPC (Special Processed Cereals) on induction of the endogenous protein AF (an antisecretory factor) in plasma and intestinal lumen in broilers. Previous results have shown positive effects on different intestinal diseases in pigs, horses, dogs as well as in humans. Beside the induction we also studied the effects on results in a conventional slaughter chicken production, including the ability of SPC to compete with or be affected by the coccidiostat, Salinomax.When diarrhoea occurs, it's because there is an imbalance between the secretion and the absorption and it can be caused by for example toxins.

Övervikts påverkan på kundmötet

The use of thin and attractive models to promote companies' products is widespread among marketers. This is true even for companies whose products have little or no association with beauty or body weight. As the proportion of overweight people continues to grow in many developed countries the ideals used by marketers to attract customers strays further away from the actual attributes of the customers themselves. What is little understood is what effect overweight has on the efficiency of the product promoter. Some limited research has studied how the efficiency of the product promoters in printed advertisements is affected by the existence of congruence between the product promoter and the product itself.
