This bachelor thesis mainly focuses on the cadmium in the environment, how we are exposed to cadmium and it´s human toxicity. Cadmium (Cd) is a heavy metal that occurs naturally in the earth's crust (0,08 -0,05 μg Cd/g). Pure cadmium minerals are rare and cadmium is often found associated with zinc minerals, such as sphalerite (ZnS) with a Cd-concentration usually lower than 0,5 percent. The

Models for dynamic simulation of a parabolic trough concentrating solar power plant were developed in Modelica for the simulation software Dymola. The parabolic trough power plant has a two-­‐tank indirect thermal storage with solar salt for the ability to dispatch electric power later in the evening and during the night when little or no solar irradiation is present. The complete system consists

When we talk about the future of work we do no longer talk about “the paper less office” like we used to but the “no fixed work place office”. In the year of 2013 26% of the Swedish population was occasionally working flexible, meaning at other locations then the actual workplace. And this number is expected to increase in the upcoming years. The research made in this project consisted of differe

Högeffektiva solceller och lysdioder samt nya typer av transistorer är bara några av möjligheterna som öppnas med nanoteknik. En av de mest lovande nano- strukturerna som studeras för framtida applikationer är nanotrådar av halvledarmaterial som galliumarsenid (GaAs). Dessa stavformade kristaller har en diameter mindre än en tusendel av ett hårstrås och förväntas bli de nya byggnadsblocken inom elSemiconductor nanowires (NWs) are expected to be the new building blocks in electronics and photonics, but improved understanding of the nanowire surfaces and electronic properties are required to realize it. In this bachelor thesis, wurtzite (Wz)-zincblende (Zb) axial heterostructure GaAs nanowires are studied using scanning tunneling microscopy and spectroscopy. The hexagonal cross section nan

Normalt åldrande kan innebära att den äldre människan drabbas av ohälsa som kan leda till minskat välbefinnande. Djur kan ha ett vårdande syfte och används på följande sätt: Animal-assisted activity (AAA), animal-assisted therapy (AAT), animal-assisted intervention (AAI). Studiens syfte var att beskriva hur interaktion med djur kan användas som en omvårdnadsåtgärd för att den äldre människan inom

Temporary work agencies operate on a business model based on the idea of hiring workers and placing them in assignments at other companies. This model has proved to be beneficial on the labour market in response to the increasing competitive pressure, the need of flexibility and a bigger variation of workforce. The Swedish labour law model is traditionally built on an employment contract between a

Since the first methadone program was introduced in Sweden during the late 60s, it has been a controversial method of treating opiate addiction. The aim of this study was to, by doing a discourse analysis, come to an understanding how the Swedish maintenance program for opiate addiction was constructed and debated in three big Swedish newspapers during the 2000s. More specifically the aim was to r
