"The Never Ending Story" : Sårbarhet och kamp för överlevnad i Olofströms kommun

The world around us is shrinking and globalization and capitalism are processes affecting the world. Global trends, like outsourcing and relocation of firms to low-cost countries, have become more common. This creates a huge vulnerability in the municipalities that today are concentrated around a single large company. One of these is Olofström which today is one of the most vulnerable municipalities in Sweden and whose survival today lies in the hand of the company ?Volvo Cars Corporation?.

Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.

En undersökning av lärarnas genusmedvetenhet : En enkät och intervjuundersökning om lärarens föreställningar och uppfattningar om genus och om det påverkar deras genusmedvetenhet

The law of 2006 about Equal treatment, has been put in place to stop discrimination of students, example based on their gender. The law has an important function to increase the equality of opportunity between girls and boys in school. Therefore the teacher has an imported roll for raising the equality of opportunity between girls and boys in school. That?s why it?s imported to work gender awareness.

Kloridutlakning från flygaska : möjligheten till en lokal hantering

In Sweden, there are limits to how much leachable substances waste must contain in order to be deposited as hazardous waste. Fly ash from waste incineration often end up over the limit, mainly due to the chloride content. Fly ash is therefore often deposited abroad. The purpose of this study was to investigate the possibility to handle fly ash locally. To clarify how the law is applied, environmental reports and permit documents from ten waste sites with permission to deposit fly ash were studied.

Risk för exponering av växtskyddsmedel i växthusmiljö

Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.

Factors for success in Swedish biogas : a study based on the Swedish agricultural sector

The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.

Koldioxidutsläpp vid sticklingsproduktion av pelargonium x hortorum i Kenya jämfört med Sverige :

Long transport of products is an environmental issue discussed to an increasing extent. The consumers are increasingly aware of how far our comestibles really have been transported. The increasing levels of environmental emissions are something that concerns people. The question is nevertheless delicate and many choose to ignore it. This is no longer an option.

Likabehandlingsprincipen i uthyrningslagen - om lön för arbetare inom bemanningsbranschen

In Sweden has the temporary agency work industry settled in an explosive way since the deregulation of the unemployment agency monopole in 1993. The demand of civil right for the employer that is rented out confronts the entire labour law regulation with new challenges.The purpose with this paper is an investigation of the principle of equal treatment in The Swedish temporary agency work act and also to create a deeper understanding of the effects of labour and employment relationship. An investigation of relevant collective agreements will be done to highlight the difficulties the principal of equal treatment is exposed to. Further on is there a will to gain understanding for the wage concept and what possible can be included in the wage concept in relation to the principal of equal treatment in The temporary agency work directive. By using the dogmatic method, an approach to descriptive identifying relevant sources of law and clarify the legal situation in the area.In the conclusions it will be determined that the principle of equal treatment in The Swedish temporary agency work act have different effects depending on if the temporary agency or if the client corporation is tied to an collective agreement alternative if a collective agreement is completely missing.

Faror i varor : En studie av unga vuxnas medvetenhet om kemikalier i hygienprodukter och kosmetika

Chemicals are everywhere in todays society, in humans, animals as well as nature, and they are difficult to avoid. The chemical industry is regarded to be the fastest growing industrial sector, accounting for ten percent of the global economy. A large amount of chemicals are used to produce hygiene products and cosmetics, products that in Sweden only are consumed in quantities of 110 tons per day. Researchers find it increasingly difficult to determine which chemicals that are dangerous and which that are safe, and how they might affect us in the long run. Correlations have been found between chemicals, diseases and other health effects such as cancer, allergies, reproductive and endocrine disorders.

KLIMATTOLERANS HOS URBANA TR?D I G?TEBORG: Analys av klimatgr?nser och framtida klimathot

Urban trees contribute significantly to our society. By providing ecosystem services and a habitat that other urban species and ecosystems depend on, both biodiversity and the people in the city benefit. Some characteristics that the trees possess include functioning as biological filters for the atmosphere and water, as well as positively impacting people's mental health. However, urban trees are challenged by stressors such as pollution and a drier environment, making them particularly sensitive to climate change. The goal of this study was to estimate the expected magnitude of climate change in Gothenburg and compare it with the current urban species' natural climate boundaries to understand the extent of the climate threat and which species appear to be most at risk.

Biologisk mångfald bland åkerogräsen. En fältstudie av två åkrar : en konventionellt och en ekologiskt odlad

Den biologiska mångfalden är viktig inom lantbruket. Jordbrukslandskapets mångfald är vacker för människan att se på och spännande och rogivande att vistas i. Mångfalden innehåller även en genbank som kan bli mycket etydelsefull i framtiden. Dessutom innebär oftast en rik mångfald bland ogräsen även en rik mångfald bland insekter och andra djur, däribland skadeinsekternas predatorer, vilket bidrar till produktiva åkrar. Ogräsens mångfald på åkern beror till stor del på geografiskt läge, klimat och berggrund.

Får handen och foten någon chans mot boken? : Om att lära in matematik ute. En studie i utomhusmatematik.

The aim of this paper is to find out to what extent outdoor mathematics is used in preschool and elementary school. I have chosen to use interviews to find it out. I made my interviews in five different schools in Karlskoga, with teachers in preschool and in first and second class. Focus has been on the positive effects in outdoor activities. The paper also deals with some of the prerequisites necessary to organize such activities.

Synchronizing migration with birth: an exploration of migratory tactics in female moose

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

Modellstudie av föroreningsretention i Bäckaslövs våtmark : Tillämpning av modellverktygen MIKE SHE WET och MIKE 21

During the nineties, ecological handling of urban storm water became very popular in Sweden. Together with Chalmers University of Technology and two Swedish communities, DHI Water and Environment has been doing research of storm water ponds and constructed wetlands. This thesis work is a part of that research project. The work has been applied at the Bäckaslöv storm water treatment plant in Växjö, Sweden. The plant consists of one storm water pond and a downstream constructed wetland.

Studier av mjölkbarhet automatiskt mätt i mjölkningsanläggningar :

Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.
