There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

Bostadsbristen för studenter, särskilt i större städer, har under en längre tid varit ett frekvent diskuterat ämne i Sverige. Stockholm har ett brett och starkt utbud av högre utbildning och regionen expanderar kontinuerligt. Regionen har idag cirka 80,000 studenter som slåss om färre än 13 000 studentbostäder. Detta medför en risk att studenter väljer bort Stockholm som studentstad.Denna studie syftar till att undersöka möjligheterna för studentbostadsmarknaden att utvecklas. Med ett kvalitativt tillvägagångsätt via intervjuer med fastighetsutvecklare och lärosäten identifierades fem problemområden som ligger till grund för detta examensarbete.

Billions of children, women and men lack access to safe water supplies, whichputs the affected in both social as well as economic despair. This paper willpresent some of the conclusions leading Non Governmental Organisations suchas the UN has presented recently concerning the terms of sustainability. Much ofit is true and important, but nothing can be done without extended cooperationbetween nations worldwide to find arguments that prevent short-term thinkingand economic wealth on the behalf of future sustainability.With a growing population and an increased competition for fresh water, theworld will soon face a severe shortage of good quality water for irrigation. This isbecause the distributions rarely match the demand, neither in Australia nor inAfrica. Important to notice is the major factor that the degradation of theenvironment is not one country?s problem to solve.

This study was carried out in the purpose of investigating the factors in the electronicmedical records system in Procapita that contributes to utility for the users and the factorsthat prevents the experience of utility for the users. The study was done within KalmarCounty and its employees within the field elderly care. The problem that we brought upwas that the elderly part of the population is growing quite rapidly whilst the gap betweensupply and demand on nurses and physiotherapists is increasing. This creates a problem ofits own in regards to how we are going to care for the elderly when there?s not enoughstaff for it.

Abstract Students' questions play an important role in both teaching and learning science. However, in a traditional classroom, the teacher is the center of attention and poses questions to which students answer. The students seldom ask questions to which the teacher responds. The purpose of this paper is to examine teachers' attitudes towards student questions. This paper will also explore teachers? views on the issues related to students? questions for science education.

Resource-based learning or problem-oriented learning are teaching methods that are becoming more and more common in schools today. In order to make these teaching methods work there is a demand to make students information literate. This entails that school librarians ought to play a more important role in teaching than before since they are the ones that are the most qualified when it comes to mediating information skills. The aim of this thesis is to find out how nine teachers at six senior high schools apprehend the professional role of the school librarian and how they apprehend the conception of information literacy In order to learn about these conceptions we have chosen to study to what extent collaboration exists in the schools in question and the teachers conceptions of the importance of the school librarian in this context. We have used phenomenography which is both a set of theoretical assumptions and a methodology.

This bachelor thesis is about illustrating the fundamental principles for planning, locatingand designing bicycle parking spaces. The study aims to give an understanding of theneed and demand for bicycle parking spaces today, as well as to determine how these canbe met according to different theories. The study also aims to investigate the issue withincorrectly parked bicycles, which occurs frequently in the cityscape and therefore createsan obstacle in street spaces.An observational study on the new bicycle lots along Götgatan was conducted in orderto analyze how the theories of bicycle parking spaces are applied in practice. Cyclistswere then interviewed in order to obtain a deeper understanding of the cyclists? revealedpreferences.

Trees in urban environment are exposed to extreme conditions, foremost the ones that grow in the hard packed soil along our streets. They are also exposed to damaging insects and fungal diseases both local and new ones spreading from South Europe. The global warming with warmer temperatures provides a longer growing season, making it easier for insects and fungus to establish a habitat. Based on these facts new tree species need to be available for future urban plantings.To determine what these trees would be an interview study began. Six people were selected who have experience in the field of urban environment planting.

In this study potential health risks for employees in connection with handling of bottom ash and bottom ash water at a Municipal Waste Incineration (MWI) plant have been investigated. Air surrounding the bottom ash and the bottom ash water has been examined. MWI is one of the primary ways to manage solid household waste, and bottom ash is the main solid residue produced by the incineration process. Bottom ash constitutes about 15-20% of the original waste. The bottom ash is extinguished in a water bath (bottom ash water).The study was carried out in a MWI plant in Karlstad, Sweden.

The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

A lot of mine waste rock and tailings arise from all mining processes and have to be stored in an appropriate way. Tailings are deposited in impoundments retained by tailings dams. The objective of tailings dams is to retain the slurry from the mining process and in that way prevent spill into the surroundings that might be harmful for the environment. Tailings dams are often constructed as staged embankments so that construction costs and demand of materials are spread more evenly over the period of deposition.The objective of this thesis has been to compile information about and evaluate events at Swedish tailings dams and also to develop a collective database for all Swedish mining companies for all tailings dams and all events that occur at tailings dams.Information about 60 events at Swedish tailings dams has been gathered and evaluated. The evaluation has been performed by comparison between and analysis of individual parameters and also by use of a multivariate statistical method called PLS.

This market study was written on behalf of Uni4 Marketing (U4M) and investigates the Egyptian softwood market. The objective was to identify what characterises a good softwood supplier according to Egyptian importers. In addition to this U4M?s competitiveness compared to their competitors was evaluated. The study also identified possible sources of competitive advantage possessed by U4M.

As the environmental awarenesshas increasedin recent decadessohas the society?s demand forenvironmentalresponsible companies(Ammenberg, 2004).One way for companies to take responsibility and work with environmental issues is to implement anenvironmental management system(EMS). EMSserves as a tool for companies to systematically work with environmental issues and develop the company's environmental efforts. ISO 14001 is theEMSaccording to whichthat the majority of companies today choose to get certified(Brorson & Almgren, 2007). The introduction and operation of the ISO 14001 requires significant financial and human resources and it can therefore be questioned whether the environmental managementsystem is adaptable forall companysizes.The purpose of this studyis to examine whether EMScan provide environmental and economic benefits for companies of all sizes and ifthe conditions to get certifiedaccordingto ISO 14001 is the same for large and smallcompanies.A literature study was made to collect information on company'simplementation of ISO 14001.

One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

Background: Sweden has, since 1983, had a statutory audit for all joint-stock companies. However, according to EG?s fourth corporation directive, member countries can decide on their own if this applies for small joint-stock companies. An investigation was launched in the fall of 2006 to form an opinion on the importance of the audit reporting by law and what an abolishment of this rule would mean for small joint-stock companies. Critics are claiming that the cost of audit for small companies is exceeding the cause in these micro companies.Audit is regulated by Swedish translation (RS) of International Standards on Auditing (ISA) and is to be applied in all companies comprised by the statutory audit.
