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.

Ovidkommande vatten i spillvattensystemet - problematik och åtgärder

The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.

attraktrivitet och regionplanering : Hur ska osby kunna ha en positiv ekonomisk tillväxt och befolkningsutveckling i region skåne?

 AbstractAttractiveness may be defined by a variety of factors but you should see it in the public planning as it is to have a positive population growth and economic growth, through working with communications, service, housing, to name a few. This is done primarily through direct projects both within the municipality and through various partnerships between local and regional level. The progress we have seen in recent years has gone more towards a clear shell level, particularly a regional level where these have had a much greater freedom with clear geographical boundaries in between each other. Within these regions there are also clear regional groupings that have common interests and competing between each other. In my thesis, we have been distinguished including three levels of scale levels.

Vem får ligga när man bäddar?: En studie om specialexponeringar och dess sidoeffekter med utgångspunkt i varumärkesstyrka

Store managers and brand owners have realized the benefits of sales promoting activities in-store, which thus have become a common sight for consumers when grocery shopping. Using in-store displays, a brand?s sales can increase by more than 1000 percent. We believe, however, that displays can give rise to additional effects to those previous studies have shown. The purpose of our study was therefore to map possible side effects that a display can generate depending on the strength of the exposed brand.

Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Hur bemöts Kina i Afrika? : En mångdimensionell idealtypsanalys av Sydafrikas, Zambias och Zimbabwes bemötande av Kinas ökande ekonomiska intresse

The outset of this study is to contribute to the literature concerning China?s increasing economic interest to engage in the African context, its economies and resource abundandce. The overarching research problem is that the approaches held by the respective African state entities may facilitate increasing development gains for the recipient state of this economic interest in principle. To adress this research problem the study is undertaken by conducting a comparative case study where three cases/states, with presumably diverging economic and political status, are likely to effect their overall state approaches differently.Research questions, which are addressed by the creation of an idealtype analytic matrix, concern whether the states of South Africa, Zambia and Zimbabwe take on a more ?permissive? or ?restrictive? approach towards China?s economic interst and whether the approaches can be looked upon on both aggratege and case/area-specific levels.The main findings are that a clear tendency of the ?permissive approach? may be noted on a aggregate level for all cases.

De kommunala miljöarbetet : En uppsats om miljömedvetenhet och medborgarskap

The work with Agenda 21 resulted in a larger focus on local participation and deliberation. The Swedish implementation of Agenda 21 is a result of these local governments´ political agendas and policies.The purpose with this paper is to examine the relationship between the citizen and the local government. It focuses on three theories of citizenship and how the view of "the environmental aware citizen?; in the local government?s municipalities policies differ and from which theory of citizenship do they come from.The analysis is of a valuing and comparing nature. The municipalities´ web pages have been the main source to generate an understanding of their view on the normative environmental work.

Optimering av distorsionseffekt med hjälp av Fourieranalys

In music performers and music-making are oftenused different distortion effects to give the desiredcharacter on the individual sound sources andinstruments.

Tocarry out this work, an extensive literature study ofthe circuit diagrams of a large number of the classicdistortion circuits implemented. In this work, adistortion effect of the character fuzz was createdfrom several other existing effects. MeasurementsFFT, frequency response have been conducted tovalidate the desired results along the given problem.The finished effect was named Instant Carlos and aprototype was manufactured.

En deal om dagen - En kvantitativ studie om hur konsumenter uppfattar varuma rken som promotas genom dagliga deals

The relatively new phenomenon of daily deals has had an amazing explosion of growth during recent years. The concept relies on offering deeply discounted products and services that a number of customers must buy in order to acquire this discounted service. Companies spend valuable resources on marketing to get customers but the effects of daily deals on the brand do not have empirical evidence. What is the customers' attitude towards companies that communicate through daily deals How is their intention to buy from that company affected This is what is the main purpose of this study. To examine how customers perceive a company, in terms of attitude toward the brand and buying intentions, when the company markets through daily deals compared to more traditional promotion.

Försörjningens paradox : En kvalitativ studie om statliga företrädares framställning av våld i nära relation

The aim of this study was to examine how state representatives prepared domestic violence, regarding the economic consequences of women exposed to violence. In order to achieve a profound and comprehensive view of the governmental keyfigures discussion we performed five interviews and studied selected governmental preparatory works between the years 1995-2015. We used theory on social construction as an approach and certain themes were more regular in our empirical material, which we compiled in three different discourses. According to our empirical material the economic situation of women exposed to violence is caused by inequality and gender power structure. The solution given by state representatives are referred to the municipality and social services.

Ingen rök utan eld - Handelseffekter av EU: s tobakspolitik

This thesis examines the impact that the Euoropean Agricultural Policy has had on the tobacco regime during the years from the start of the Common Market Organization for Tobacco in 1970 til the days of today. The Truman method has been employed to estimate the degree of change of trade creation or trade diversion on the domestic market and also on the worldmarket. From these facts an analysis has been made to investigate how and if a new reform of the CMOT will affect the European tobacco market. Through the CMOT, the European Commission has tried to rise the quality level and the prices of raw tobacco growing in Europe. The european market value for tobacco has been rising and a marginal grade of of trade creation within the union and a grade of trade diversion to third countries has been shown since the implementation of the tobacco regime.

Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige

Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.
