Phycoremediation of pesticides using microalgae

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

Programverksamhet: ett uttryck för folkbibliotekets identitet

This thesis is a contribution to the discussion on the public library?s institutional identity in late modernity. The aim is to shed light on the public library?s identity as expressed through its public events. The thesis seeks to answer the following questions: What kind of public events are offered at public libraries? What themes distinguish the content of these events? What characterizes the institutional identity expressed through these events? In addition to the concept of institutional identity, a model of four library spaces, developed by Skot-Hansen, Hvenegaard Rasmussen, and Jochumsen, constitutes the theoretical framework of this thesis.

På väg. En undersökning av en svensk stadsmotorväg

The purpose of this essay is to examine one of Sweden's oldest motorways in cityenvironment. The researched section is motorway E20 east of Gothenburg. Olskroksmotetin the west and Jonsered junction in the east, a distance of about 11 km. The mainquestion was, can maintenance of areas and objects related to the motorway give greatermeaning to a system that currently lacks historical connection?The survey was partly an archival study and partly a physical examination of themotorway and its appearance today.The road through Säveedalen from Gothenburg has a long history that begins with theriver and its valley as transport routes.

Karlskrona: örlogsstad och världsarv : en fallstudie om stadsidentitet

In 1998, 'the Naval Port of Karlskrona' was inscribed as a World Heritage Site by UNESCO and thus, it is equally protected as China?s Great Wall and the Pyramids of Egypt.The essay is a case study of Karlskrona, one of Sweden's most well planned cities, where famous urban planners and architects such as Erik Dahlberg and Nicodemus Tessin the Elder has been involved.Today, Karlskrona is a rather unknown small town in Sweden's outskirts, where population growth has been a problem. When Karlskrona was founded, in the late 17th century, Sweden was a major power. The Blekinge archipelago was in the middle of the Baltic dominion and Karlskrona represented a midpoint in the kingdom. Therefore, Karlskrona has a small town charm with the history and style of a cosmopolitan city.By initially studying how the town?s character of today is expressed, the history of Karlskrona is explored.

Nöjda kunder med risken i fokus : En studie i hur finansiell risk bör förmedlas

During the last decades major changes has occurred at the financial markets, meaning an increasing supply and a greater variation of financial instruments. The saving habits of the Swedish people have gone from traditional bank deposits to investments in equities, funds and bonds. All this together with the great rise in the stock market at the late 90?s has brought words like risk and return up-to-date, and is the background to the development of a new law concerning financial advising which come into force the 1th of July 2004. The contents of the thesis can be described as three bricks, representing the survey questions.

Förnuft och känsla : En studie av kokböckers visuella kommunikation under det tidiga 90-talet och sena 00-talet

The interest for food and cooking has probably never engaged the people of Sweden as much as it does today. Especially cookbooks are selling better than ever which has been a quite constant trend since the mid 90's. This study explores the connection between visual communication in Swedish cookbooks and the post-modern values which have influenced the market climate and the visual culture. I have used a theoretical framework as reference consisting of theories of semiotics, visual rhetoric, marketing communications and postmodernism. I have been studying six cookbooks, three from the late 00's and three from the early 90's, from the two separate angles of their graphic design and photographic material.

VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

Skördemetoder av industrihampa :

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.

Studenters medieval- från vardag till kris : En kvantitativ surveyundersökning

Bakgrund och problem:Belöningssystem alltid varit ett styrverktyg där ledning med dess hjälp försökt att bidra till att medarbetare blir motiverade till att öka sin produktivitet och på så sätt bidra till organisationens lönsamhet. Men att försöka förstå de icke-ekonomiska effekterna av olika belöningssystem har bidragit till att försöka skapa en ökad förståelse för organisatorisk rättvisa. Vad gäller monetära ersättningar i ett belöningssystem så är det viktigt att förstå att rättvisefrågor utgör en viktig del av de olika anställningsförhållandena i organisationen. Utan denna förståelse kan det uppstå ogynnsamma situationer. Detta har lett oss till uppsatsens problemformulering: Vad har upplevd rättvisa för påverkan på attityder kring monetära ersättningar i ett belöningssystem?? Vad kan monetära ersättningar få för upplevda beteendemässiga konsekvenser?Syfte:Rapportens huvudsakliga syfte är att beskriva och förklara attityder kring monetära ersättningar i ett belöningssystem.

Läkemedlet Oxazepam påverkar abborryngel : Exponering under embryonalutvecklingen ger effekter på tillväxt, överlevnad och beteende

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Kväveomsättning i gräsmark med olika artantal och artsammansättningar :
