Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action

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.

En geopolitisk återkomst : Kultur, ekonomi och territoriell konstruktion i samband med inomstatliga konflikter

Through geopolitical theory this thesis explores how conflicts within states can be read and understood according to an analytical model determining one or several possible causes for the conflict.  The model is created by the author and reflects geopolitical theory by giving three possible explanations to an intrastate conflict: culture, economy or territorial construction. The aim of the thesis is Testing this model on two selectively chosen case studies ? i.e. two intrastate conflicts ? namely: the upcoming referendum in Scotland and the terror attack at Tiananmen Square in China.

Den litterära nätsajten Vulkan.se och en ny modell för den litterära processen

The aim of this thesis is to investigate how the literary site Vulkan.se affects the conditions for publishing, distribution, incorporation in value systems and feedback in the literary process, as it appears in Lars Furuland?s model of this process. The purpose is also to propose an updated version of the model. This is achieved through a qualitative Testing of Furuland?s theory.

Översättning av Western Aphasia Battery ? Revised samt en jämförande studie med A-ning med personer med afasi

New tools for the assessment of aphasia are important for bothclinical work and research. To see how they relate to already existing testscan increase their usefulness. Western Aphasia Battery ? Revised was translatedto Swedish and compared with the Swedish aphasia test A-ning, partlyto compare content and partly to see how sixteen people aged between 22and 92 with aphasia performed on the tests. The subtests did not correspondcompletely and the type of items included varied a lot.

Sveriges säkerhetspolitik under 2000-talet : En analys ur ett liberalt och ett realistiskt perspektiv

The purpose of this study was to examine and explain Sweden?s defence and security policy during the twenty-first century. The method that was used in this research was a case study. The material that was used were government documents focusing on this area of policy, and numerous books concerning the theoretical perspectives on international relations and defence security policy. The study is of an explaining art and the analysis explains Sweden?s security and defence policy during the twenty-first century. The analysis explains this by Testing it against a liberal and a realist view on international relations. The conclusion of the study is that Sweden?s defence and security policy has been liberal during this time period ? and still is.

Hållbarhetscertifiering av stadsdelar : En jämförelse mellan existerande certifieringssystem

This bachelor thesis describes the process of developing a two wheeled robot with activebalancing. The robot is designed to go straight ahead until it reaches a finish line.

Hur man vinner ett val i Sverige

Studies have found that the applicability of commercial marketing strategies within politics have increased in recent years as a result of a rising number of swing voters. The purpose of this paper was to investigate the effects of the commercial theory of incongruent information in political marketing in Sweden. Subsequently, an experiment with 742 participants was conducted, Testing the effects of congruent and incongruent ad messages for two established Swedish parties. The effect of ad message choice on several well-established measures of ad effectiveness such as awareness, credibility, attitude, conviction and voting intentions was analyzed. The results showed that incongruent information effectively increases attitude, conviction and voting intention for voters who decide on the election day what party to vote for.

Effekten av neutrala påståenden på social önskvärdhet i självskattningsformulär

This study investigated the effect different contexts have on personality items when they are framed more neutrally. The study was based on a five-factor personality inventory originating from International Personality Item Pool. The inventory consisted of 50 original and 50 neutral personality items and in addition 28 items measuring social desirability. The sample consisted of 150 students from the Department of Psychology, Lund. The students were divided into three instruction groups differing in context.

Bland kockrockar och rock-kockar  - En retorisk analys av svenska matlagningsprogram

Aim: The purpose of this paper is to see if there has been a change over time in the performance and in the spoken word of the Swedish cooking programs. By Testing the theory of intimization on the cooking programs I get the opportunity to see if the border between the private and the public have become clearer or more difficult to notice, and if the new language, the informal language as intimization entails, has been used in Swedish cooking programs since the 70s until today, or if there´s ever been a formal language in Swedish programs? Method/Material: I'm using a rhetorical approach that includes a three-step analysis. Analysing the context, means to persuade and performance. The empirical material I intend to analyze is Swedish cooking programs from the 70s until today, 2010.

Kvantitativ studie om knappsatsdesign och knappstorlekars påverkan på träffsäkerhet

A mobile Testing application using Unity was developed to analyse what impact button sizes and button layouts has on the accuracy of touch as well as the time to finish a labyrinth. This was tested on a Nexus 4 phone. 28 users navigated a small object through a labyrinth in which they collect keys to open the door to the exit. Each participant did the test 6 times with different combinations of button size and button layout each time, done in a random order. Hits, misses, completion time, order of button size and order of button layout was collected and then visualized using R.

Flyt tillsammans : Emotionell gemenskap i kooperativa spel

Studien undersöker känslomässiga reaktioner vid kooperativt spelande, vilka som är gemensamma för båda spelarna och hur de påverkas av hur svårt spelet är. Arbetet utgick från studier av spelares emotionella reaktioner på spel och teorierna om Flow. Spelet Sanctum användes i en serie tester där mätningar utfördes på två spelare med hjälp av rapportformulär, pulsmätare och hjärna-till-datorgränssnittet Emotiv EPOC. Studien fann att spelarna ibland upplevde samma känslor när de spelade tillsammans och att den ökade svårighetsgradens huvudsakliga effekt var att förändringarna i känslorna blev skarpare och större. Det tycktes huvudsakligen vara motgångar som splittrade spelarnas upplevelser.

Experimentell undersökning av provkroppar för trälimfogar

This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

Detektion av mRNA från en cytokrom c gen belägen i genklustret för kloratmetabolism i Ideonella dechloratans

Abstract:In previous experiments with the bacterium Ideonella dechloratans a probable sequencecoding for a cytochrome c protein (cyt c) was observed, the sequence is assumed to have afunction in the bacterial respiratory chain. Detection attempts have been made to try to findthis protein, but have not succeeded. The purpose of this project is to detect the expressionof mRNA associated with the cytochrome c. And if it is detected, it will also be investigated ifthere is any difference in expression of the mRNA due to aerobic or anaerobic environment.Total RNA was purified from cultures grown under aerobic and anaerobic conditions. cDNAwas then synthesized using reverse transcriptase and subsequently amplified with thespecific primers in a qRT-PCR.qRT-PCR Testing showed a distinct amplification of primer product, confirming that I.dechloratans expresses mRNA coding for the cyt c protein.
