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.

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.

In music performers and music-making are oftenused different distortion effects to give the desiredcharacter on the individual sound sources andinstruments. These have different names (fuzz,distortion, overdrive) depending on the character. 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.

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.

Global uppvärmning : gymnasieelevers oro och kunskap

Global warming is generally recognized as one of the major environmental challenges we have to face in the near future. The students in school today are the ones that will have to deal with the consequences of it tomorrow. That is why education about it is so important. Previous research shows that students believe that environmental issues in general are important problems to be solved. I this study I tested students in grade twelve, in four different schools in order to find out what their level of knowledge about global warming is, how worried they are about it and if there are any correlation between their knowledge and their level of worry.

EKONOMISKA SANKTIONER P? BEKOSTNAD AV M?NSKLIGA R?TTIGHETER? En kvantitativ studie om den regionala effekten av ekonomiska sanktioner p? graden av m?nskliga r?ttigheter i icke-sanktionerade l?nder

Previous studies have shown that economic sanctions have adverse effects on the level of human rights in sanctioned countries. The focus of research on the effects in sanctioned countries has left the question of whether economic sanctions can have a regional effect on human rights levels in countries not sanctioned in the same region. Therefore, this essay has sought to investigate if economic sanctions aimed at an individual state have a regional effect on the level of human rights in countries not sanctioned within the same region. A previous study found that economic sanctions in Latin America positively affected the level of human rights in non-sanctioned countries within the same region. This essay has examined whether the same result can be found in a region with a different level of democracy.
