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.

Många hushåll och individer har i dagens samhälle tvingats börja pendla till sina arbeten bl.a. på grund av en förändrad arbetsmarknad. Syftet med föreliggande studie var att se om individer som pendlar regelbundet har ett lägre KASAM. Utgångspunkten var att individer med en mer extern kontrollokus ofta har lägre KASAM och att pendling hypotetiskt sett bör påverka individen lokus i en extern riktning. Sammanlagt 27 försökspersoner i åldrarna 22 ? 50 år undersöktes med hjälp av KASAM test och I-E test.

Orofaciala funktioner såsom mimik, tal, tuggning och sväljning är viktiga för livskvaliteten. Det råder generell brist på normerade test som bedömer dessa funktioner och därför har Nordiskt Orofacialt Test ? Screening (NOT-S) utvecklats. Syftet med föreliggande studie var att normera NOT-S för barn med typisk utveckling i åldrarna 3:0-6:0 år. Testet består av en strukturerad intervjudel och en undersökningsdel med sex avsnitt vardera.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

Swedish students' knowledge of both mathematics and reading comprehension has deteriorated in recent years. Scientists are discussing whether there is a connection between these areas and that the pupils deteriorating math skills may have something to do with their increasingly lower results in terms of reading comprehension. To investigate this possible connection, I conducted a survey among students in ninth grade and have come to the conclusion that the scientists are right: this connection absolutely exist. Students who received a high score on tasks designed to test students' mathematical problem-solving skills, also received high results on the reading comprehension test. And students who received a poor performance on the problem-solving tasks, were also low performers in the reading comprehension test.

This study highlights the differences in articulation, nasality and intelligibility between twenty 16-year-olds and thirteen 19-year-olds born with isolated cleft palate and control groups. The test groups are compared in a longitudinal perspective and based on earlier evaluations of velopharyngeal impairment. Significant differences were found between test groups and control groups using quantitative comparisons based on SVenskt Artikulations- och Nasalitets-TEst and NasometerTM. The longitudinal comparison also showed a positive but not significant development of the speech. Differences emerged in the comparisons based on velopharyngeal impairment but no significance analysis was made.

Teorier inom Kognitiv hörselvetenskap beskriver hur uppfattning av tal beror på två olika typer av processer. Bottom-up processer associeras med akustiska och fonetiska egenskaper hos en inkommande signal och top-down processer associeras med lexikala, syntaktiska, semantiska samt kontextuella egenskaper. Förmågan att utnyttja top-down processer tros bero på kapaciteten hos arbetsminnet. För att undersöka en skillnad mellan bottom-up och top-down samt deras förhållande till arbetsminnet har ett Speech-in-Noise (SIN) test utformats och genomförts på 15 försöksdeltagare. Testet undersöker skillnader i tröskelvärden för att identifiera ett enstavigt ord i ett uppåtgående förhållande till stationärt brus, mot tröskelvärden för att identifiera ett enstavigt ord i stationärt brus med hjälp att top-down stöd.

Vole populations in northern Scandinavia vary in cycles with peaks every third or fourth year as described by the National Environmental Monitoring Programme of small mammals (NEMP). Some vole species have declined in population numbers since the NEMP started in 1971, especially the grey-sided vole (Myodes rufocanus) which is nearly extinct in the forested region. Since small mammals are an important food source for several avian and mammalian predators, the decline in vole numbers is expected to have consequences for the whole food chain, especially if other vole species start to decline in numbers. This study tried to test the hypothesis that presence and abundance of M. rufocanus (a specialist species) and Myodes glareolus (a generalist species) can be predicted by patch size and connectivity of forest patches >60 years old with a minimum of 15% pine >100years old.

Our work is based on a mathematics test which the students accomplished, interviews with student and teachers who are working on this program and the current literatures. The purposes of this work are to search the importance and the effect of the languages understanding in students learning of mathematic in the Individual high school curriculum. In total, sex students and three teachers took part in our study. Tow of the students is mother tongue language student and the remains are second language student. Our study should answer tow important questions:? Do the student in the Individual high school curriculum have the fundamental knowledge in mathematic?? How does the understanding of Swedish language effect in the understanding of the mathematic problems and in the students results in mathematic test?In order to answer those questions, the students have to complete a mathematic test that consists of four parts.

The aim of this thesis is to investigate how Bahamas, a magazine belonging to the antideutsche current in German left-wing politics, acted during a two year period between the summer 2001 and 2003. When explaining the anti-deutsche phenomena and the editors? politics it is common to take the currents own history-writing as a fact, thus presenting the development of the current as a reaction to outside factors and impulses outside. In this thesis it is stressed that the editors are far from only passively reacting, rather the opposite is true. I claim that the editors have a fixed ideology that they strive to implant in to certain parts of the radical left.

All inclusive travel has become a popular way to travel abroad. When tourists pay for everything in advance their need for contact with the local people will be reduced. The consequences of this can be dissatisfaction from the local people as they are left out and do not share the financial benefits created by tourism. During the purchasing cycle of an all inclusive travel, it is possible that the tour operator can influence a sustainable development.The aim of this paper is to compare how a large and a small tour operator in their purchase of all inclusive holidays interacts with local players to create sustainable development, thereby creating a surplus value to the customer. The hypothesis is that the amount of knowledge and application of this knowledge regarding sustainable development differs in the purchase process between large and small tour operators.This paper was carried out as a case study.

The company Microshop is interested in implementing new features in their product-website, and would like to examine the possibility and usefulness of introducing such functionality. When designing interaction for commercial websites, it is important to make the menus easy to use, and refrain from using deep hierarchies in order to avoid causing unnecessary burden for the users. There is an interest among users for adaptive functionality, but this requires great amounts of trust in the website from the user. Something which can be created by refraining from using implicit information, and provide detailed explanations throughout the website. A usability test was conducted in order to complement the data gathered from the theoretical study, the interviews and the expert evaluations.

This paper is a compilation of some of the important viral zoonosis that can be passed from apes and simians (simian and prosimian) to man. Viral zoonoses are viral diseases that can be passed from animals to humans. The paper will also provide a better insight of the risks workers and visitors to the zoo can be exposed to. The viruses that this paper is focused on is herpes Bvirus, simian T-lymphotropic virus type 1 (STLV), simian immunodeficiency virus (SIV), Ebola virus, Marburg virus, yellowfever virus, monkeypoxvirus and hepatitis B virus. The choice of viruses is based on how infectious they are and how pathogenic they are.

Detta examensarbete har gjorts på uppdrag av Compare Testlab på Sätterstrand, Hammarö. Målet med arbetet var att de?nera en uppsättning frågor och punkter som ska vara med i ett lättviktstest med inriktning på säkerhet. Efter mycket studier av böcker och webbsidor kom vi fram till att det inte var så lätt som vi trodde att de?nera ett allmänt säkerhetstest för mjukvaror eller applikationer.
