Perenner i Norrbotten - Ja, varför inte? :

In this thesis, I have discussed which (herbacious) perennials that are sold most in the county of Norrbotten in the upper north of Sweden. Also discussed are the factors considering overwintering and factors that affect the chances of survival. The reason to the subject is that I m born and raised in Norrbotten and throughout the years I ve wondered why so many of the perennial flowerbeds look so similar. The purpose of the thesis is to give another approach to the composition of the garden by explaining some of the factors that controls the survival of plants. The information is gathered partly through interviews with plantshop personnel and partly by a literature study. The results of the interviews reveal that tradition and hardiness is the major reasons to the consumer s choice.

H?RNERVMOSSANS P?VERKAN P? LJUNGHEDENS ARTM?NGFALD: En f?ltstudie fr?n Sandsj?backas naturreservat

Campylopus introflexus is a moss species that originates from the southern hemisphere and has spread worldwide during the 20th century. Today it is classified as an invasive alien species in many countries, and it has been seen during inventories that it has become widespread in Sweden as well. The purpose of this essay is to contribute to new knowledge about how this moss affects species diversity on Calluna heathlands in Sweden. The study includes both fieldwork and an analysis of scientific literature on the subject, and the question that is answered is if C. introflexus has an impact on species richness in the heather peat.

Riskbedömning vid Saltvikens kopparverk

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Habitat preference and foraging behaviour in adult red-tailed monkeys (Cercopithecus ascanius)

The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.

Hur publicera efter policyn? Ett antal seniora forskares förhållningssätt till open access efter Vetenskapsrådets open access-policy.

Since the 1990?s Open Access has developed into an alternative model for scientific publication. Today an increasing political interest in promoting Open Access is commonly channeled through the implementation of policies by research funders. However, in the scientific community the uptake and acceptance of the model has been of notably different character.This Master?s thesis examines the understanding of and attitudes towards open access among eight senior Swedish researchers and how these have been affected by the implementation of the Swedish Research Council?s Open Access-policy as implemented in 2010.

Mjukvarukvalitet i öppen programvara - en explorativ och kvalitativ studie av uppfattningar om mjukvarukvalitet

Open source software has recently been discussed, not least in media as a revolution in IT. A number of advantages have been listed in changing proprietary software into open source software. Examples of such pros are no expenses for license fees and improved efficiency. In spite of this, few users have made this change. One of the reasons is a distrust of the quality in open source software.

Nature of science i skolans tidigare år - Intervjuer med lärare som integrerat Linnés 300-årsjubileum

För att alla elever ska kunna uppnå scientific literacy bör man utgå från barnens erfarenheter där naturorienterade ämnen, NO, knyts till ett sammanhang ? en kontext. I kontexten synliggörs naturvetenskapens mänskliga sida, och därmed visa att NO är mer än fakta. Elever behöver lära om naturvetenskapen, vilket kallas nature of science, NOS. Vårt syfte är att ta reda på hur lärare aktualiserar nature of science genom ett Linné-tema.

Åtgärder för unga arbetslösa och deras påverkan på jobbstatus och hälsa

Several reports and scientific research have shown that unemployment affectshealth negatively and that it is the young unemployed who suffer the most. Despitethis, there were not many evaluated labour market programs for young peoplefocusing both on how the labour market programs affect the job status and health,most of them were only focused on job status. Since there were not manycompilations in that direction, the essay is intended to describe the variousprograms and their impact on both job status and health. A literature-based studyhas been conducted and 15 articles have been reviewed and compiled into variouscategories using a content analysis. It turned out that the majority of the mostcommon labour market programs were represented in the scientific literature.There was also a new genre that is not mentioned in previous reports, cognitivebehavioral therapy (CBT), which proved to be one of the most successful programs.Michigan Prevention Research Center (MPRC) job search programs also showedsome positive results.
