In an effort to evaluate the effects of restorations of float ways on population density of stream dwelling fish in relation to the changes in habitat, I studied the physical habitat restored and channalized sites and their population density of brown trout (Salmo trutta L.) in three streams in the municipality of Sorsele. The differences between the channalized and the restored sites where most noticeable regarding substrate which where generally coarser in the restored sites. The analyses showed that the proportion of habitat that where suitable to the age class 0+ where significantly lower in the restored sites compared to the channalized sites. Regarding age class ?2+, no statistical differences in habitat quality were found.

Den här rapporten är gjord för ett kandidatexamensarbete på KTH inom programmet industriell ekonomi med inriktning mot energisystem och hållbar utveckling. Bakgrunden till studien är den ökning av andelen elektricitet i Sverige som genereras från förnybara energikällor, där lagstiftning och politiska mål kring utsläpp av växthusgaser har varit drivande faktorer. Vindkraft är en av dessa förnybara energikällor och produktionen av elektricitet från vindkraft har på senare tid ökat kraftigt i Sverige.Den ökade mängden vindkraft som ingår i det svenska energisystemet ställer ökade krav på regleringen av produktionen i elnätet då vindkraftens effekt varierar med vindhastigheten, den är intermittent. I dagsläget är det främst vattenkraften som används för reglering av vindkraften, men den är till största del utbyggd i norra Sverige och transmissionsbegränsningar i elnätet gör att dess förmåga att reglera elproduktion i södra Sverige är begränsad.Studiens mål är att svara på om det finns teknologier för lagring av energi som är lämpliga och ekonomiskt hållbara för användning i Sverige samt hur dagsläget för vindkraften ser ut i Sverige. En omfattande studie av de i dagsläget aktuella teknologierna för lagring av energi utförs.

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

For a long period of time there has been an extensive documentation of how things are presumed not to be at our workplace. However there is little knowledge on how it is supposed to be, what makes us feel good and what makes us retain our well-being. The aim of this study was to survey the attitudes towards factors of well-being at the workplace among personnel at four institutions at Kristianstad University. The work method used in this study is quantitative and a questionnaire survey was carried out to produce an overall picture. The majority considered praise from manager and the opportunity of development discussions of great importance.

This bachelor thesis in tourism studies focuses on people's use of social media related to travel.

The intention was to provide an insight into the phenomenon to contribute new awareness that destinations can exploit in their marketing.

Background and problem discussion: Sustainability reporting has recently risen in importance and a rising number of companies choose to issue voluntary stand-alone sustainability reports. Their non-regulated nature increases the opportunity for management to angle the information in these disclosures to their own advantage. Lately the focus has shifted from examining what kind of information is provided in environmental disclosures, to analyzing how the information is presented.Purpose: The purpose is to examine if managers in the energy sector use optimistic tone when issuing sustainability reports. The aim is to find out if the tone applied in environmental disclosures is in congruence with either the environmental or economic performance or if an excessively positive tone is being used to mislead readers.Limitations: This study is limited to information found in environmental disclosures from private companies in the energy sector, issued in 2012 or 2013. Environmental performance is defined as the amount of CO2e emissions and economic performance refers to annual company revenues.Methodology: The quantification of optimistic tone is conducted using a content analysis, relying on a pre-specified wordlist and a pilot study.

Background: In 1994 came the general prescription law in force for the district nurses with specific training in pharmacology and pathology in Sweden. According to The National Board of Health and Welfare from 2004 follow-up of the use of the prescription law revealed that nearly half of the district nurses used their prescription once a week. According to previous research the district nurses and patients were positive to the district nurses administration of prescriptions. Doctors, contrariwise, were not as favorable to the district nurses administration of prescriptions. The responsibility of the heads of the health centers is to promote the district nurses to prescribe and make sure that it works in a satisfactory manner.

This paper examines if trading suspensions on Nasdaq OMX Nordic - Stockholm work as a contributing factor in creating a secure trading. This has been made through an event study and examination of abnormal returns. Our results for plus tick suspensions indicate that suspensions fulfill their purpose in creating a more secure trading since the trend of abnormal return we observe prior to a suspension is disrupted. Thus, the suspension is warranted. The conclusion is that the market cannot be completely safe; as the law and practice is structured today an abnormal return is inevitable.

In nature settings people often experience positive emotions. Litterature and theories about the positive effect of nature on humans are largely based upon visual impressions and aesthetic preference. The purpose of the present study is to examine how visually impaired individuals that lack visual impressions experience nature. The background is about what it means to be visually impaired and what it is like to be visually impaired in a nature setting, followed by a presentation of the five human senses and about stimulation of senses in healing gardens. That is followed by theories about the health promoting effect of nature, about why nature and therapeutic gardens make people feel good. After that theories about experiences and relations with settings are presented.

More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations. Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist. There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.

Social work as an traditional aid is an area that provides welfare services financed from public funds, which is one of the methods of microloans. Microloans have since the mid-1970s has become an increasingly common tool in the fight against poverty. Instead of purely assistance is now offered microloans from more banks and other institutions, as well as NGOs (non governmental organization). This paper aims to study whether and how microcredit can contribute to the empowerment of women in Bangladesh and India. This study is based on a qualitative text analysis, and has hence been based on a number of reports and articles. The paper examines, from a radical feminist perspective how microcredit can fight and eliminate poverty, and how empowerment can help women in developing countries to become independent and liberated. The introduction of micro-loan is considered to have positive effects on women's empowerment in the short term. But it is, however, the longer term effects that are considered to have the greatest positive impact on society's unequal structures.

Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

The aim of this Master's thesis was to examine the political and cultural reasons for making music materials compulsory at Danish public libraries by the new library act of 2000. The aim was also to examine how the public libraries have responded to this reform. To answer these questions a literature study was conducted as well as interviews. The results of the literature study indicated that the main reason for making music materials compulsory is to increase the influence of the library users. The study of the debate concerning the new library act showed that a majority of the Danish political parties as well as the Danish library organizations had a positive attitude towards the new obligation.

Purpose: The purpose of this study has been to investigate whether Frennberg & Hanssons earlier study of anomalies still are correct, and if these are valid for certain sectors. Methodology: In an effort to find seasonal patterns on the Swedish exchange market, we have used the average daily returns. By using these patterns we have created investment strategies which have then been tested over a 10 year period. We also used t-tests to verify our results. Conclusions: We have been able to prove a change in the seasonal patterns that Frennberg & Hansson presented in their study.
