Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Detta examensarbete utgår från en egen idé och har inte genomförts i samarbete med ett företag eller annan uppdragsgivare. På grund av detta har arbetet varit mycket fritt, vilket har gjort vikten av eget ansvar större.En lösning för att hänga upp cyklar på barnvagnar är något som fattas på marknaden. Det kan tänkas vara ett litet problem, men en lösning borde ändå finnas tillgänglig.  Eftersom det finns så pass många olika varianter av barnvagnar har detta arbete fokuserats mot att konstruera en cykelhållare som passar till en typ av barnvagnar. En prototyp har också byggts för att utföra tester på.Som metod har Fredy Olssons Primär- och Principkonstruktion använts.

Since the demands from authorities regarding lower energy consumption havebecome increasingly strict, this puts new pressure on designers and builders, who notonly have to ensure an esthetically pleasing building, but also make sure it issufficiently efficient to pass under new laws and regulations.This thesis takes into consideration a wide range of various parameters and theireffect on a building?s energy consumption. For this evaluation a computer softwarecomparison between the two programs Autodesk Ecotect Analysis and AutodeskProject Vasari was performed.Autodesk Ecotect Analysis is better suited for studies made on individual factors whileAutodesk Project Vasari is better used in experiments regarding the geometricalshape of the stucture itself.The results from the two different software tools used, give us both differences andsimilarities. For instance, both software programs produced the same resultsregarding the importance of the windows of the buildings to ensure a highly energyefficient building, both when it comes to the windows size and their U-value..

Author: Karl LarssonTitle: Samverkan mellan skola och socialtjänst ? en studie i attityder och kunskapThe overall purpose of the studie has been to explore inter-professional work between social workers and teachers. The main focus has been on the link between attitude and knowledge. Attitude and knowledge has also been tested for any connection to age, gender, what kind of a teacher you are and for how long you have been a teacher.The collected data has been analyzed in a descriptive part, one part with correlations and in one part with t-tests. The terms samsyn (consensus) and attitude has been reviewed in its connection to the results.The study shows a significant correlation (0.222*) between knowledge and attitude.

This thesis which is about working with mathematics teaching has no effect/impact on performance and understanding of pupils. The study is intended to gain insight on working in mathematics education which has an impact on performance and understanding of students who are ethnically Swedish and foreign ethnic. In order to compare the ethnic Swedish and foreign students of ethnic understanding, I judged from their performance on the tests taken in year three. The qualitative approach permeated the work, both interviews and observations which were included in the survey. The qualitative study was chosen to get an understanding of how mathematics teaching is conducted in two different areas.

As the quality of internationally competing horses is increasing, a debate concerning the breeding goal of the Swedish Warmblood horse has arisen. Some people claim that the breeding goal should be divided into two separate goals in the future; one for show jumping horses and another one for dressage horses. At the same time others claim that since the largest group of people using the Swedish Warmblood horse today is amateur riders, the needs of these riders should be taken into a larger consideration in the breeding program. The largest emphasis in this matter is on the horses? temperament. The objective of the study was to investigate what the majority of the Swedish horse people think about a variety of questions concerning today?s breeding goal of the Swedish Warmblood horse.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

The bachelor's thesis is to examine the explanatory factors affecting the choice of capital structure in real estate companies. The analysis is based on data collected from the main financial reporting from 2007; all listed real estate companies listed on Swedish, Norwegian, Danish and Finnish stock market. Based on previous research and theories, we have defined five independent variables that are linked to the debt ratio, which are: profitability, growth, firm size, cost of debt and operational risk. The statistical tests have resulted in that we can say with certainty that profitable firms tend to have a lower debt to equity ratio. We can also say with certainty that property companies with high interest costs have a high level of indebtedness..

Arbetet handlar om Piteås nya konserthus studio Acustikum som skall byggas vid musikhögskolan. En studie är gjord på stora konsertsalen. Ett bra inomhusklimat är ej lätt att uppnå eftersom hårda ljudkrav gör det svårt att tillföra luft i tillräcklig omfattning. Det finns vissa krav avseende luftflöden, men bara för att de är uppfyllda så är det ändå inte säkert att det blir ett bra klimat. För att kunna förutse lufttemperaturen i salen så användes CFD simulering.

This paper aims to describe and discuss psychotherapy in rhetorical terms; in particular how psychotherapists can use their ethos, or person, as a means for convincing the patient, and subsequently discuss how these insights in turn can be useful for other rhetors.Classical rhetoric is commonly associated with one speaker exercising influence on an audience of many, but modern rhetoric is broader, and includes all situations where someone is attempting, by speech or in writing, to affect anyone, including the rhetor himself. With this broader definition, psychotherapy may also be considered a form of rhetoric. Psychotherapy does, however, highlight the aspect of power distribution, in that it is clear that it is up to the patient to determine whether the rhetoric will achieve its purpose or not, that is, if he will be influenced by it. In psychotherapy, it is also important to differentiate between persuading and convincing: for a permanent change to occur in the patient?s thoughts and actions, the deeper, "internal" form of conviction is necessary for change to take place.When attempting to convince an audience, it is important for the speaker to establish a credible ethos, that is, present a trustworthy persona.

The aim of this thesis is to examine the existence and prevalence of earnings management in Swedish companies. Theoretical frameworks often suggest that there are strong incentives to practice earnings management. The research area of earnings management has, to date, mainly focused on detecting earnings management. However, to our knowledge, no such studies have been conducted on Swedish companies. This thesis provides evidence of the existence and prevalence of earnings management in Swedish companies.

I denna C-uppsats har vi undersökt hur ideella arrangemang av svenska festivaler går till. Vi har valt ut Hultsfredsfestivalen i Hultsfredskommun och Skogsröjet i Finspångskommun för att kunna analysera debatten kring festivaler i det lokala och nationella medianätverken samt även hur samarbetet mellan kommun och festival har utvecklats. Vi utgick från teorier av Andy Bennett där han diskuterar vikten av festivaler kopplat till ungdomskultur och att en festival är så mycket mer än bara en plats att lyssna på musik, som även stöttades upp av andra teorier av bland annat Kirstie Jamieson. Vi genomförde en analys och jämförde de teorier vi utgick ifrån med den historiska utvecklingen av festivalerna, för att sedan kunna se vad festivalerna har bidragit till i respektive ort som de äger rum på. En fråga som vi har utgått ifrån är om festivaler har utvecklats till den grad att de idag kan ses som kulturarv.

The present study aims to examine how teachers write polemical articles. This genre often occurs in national standardized tests in Swedish schools. The study seeks to analyze argumentative structures in the articles. It also categorizes assessment notes written by the teachers in response to each others? articles, by interpreting response texts.    The examination shows that there is uncertainty among the teachers about how to create structures in argumentative text types.

Enligt lag måste avloppsvatten renas och tas om hand innan det släpps ut igen. Det är det som reningsverken gör, i Hede och Björnrike är det fällningsdammar med aluminiumsulfat som doseringskemikalie.I avloppsvatten finns bakterier, som kan orsaka sjukdomar hos människor och djur om det finns i för stora mängder. I denna undersökning ser man hur mycket bakterier det finns per 100 ml vid reningsverken i Hede och Björnrike, detta är för att se om att aluminiumsulfat är en bra kemikalie att använda för att få så lite bakterier som möjligt efter reningen.För att genomföra denna studie användes miljörapporter från Härjedalens kommun och vattenprover togs vid båda reningsverken vid två tillfällen.I resultatet ser man att detta är en metod som fungerar då antalet bakterier är så pass lågt när reningen är klar att det inte är någon fara ur hälsomässig synpunkt. Detta visar då att fällningsdammar med aluminiumsulfat är en av de reningsmetoderna man kan använda för att ?knäcka? dessa patogena mikroorganismer..
