In my work I have chosen to examine the profitability for small scale production of hemp briquettes. My study also includes a review of which briquette technique that is the most common one among small scale producers. The reason that I have chosen this subject is because of the discussions about climate and energy that we face almost every day. I also think the subject is extra interesting in these days when the grain prizes are at a historic high level. In order for me to achieve a reliable report, a hemp and briquette producer has given me the actual data from his farm. In that way I have been able to make my calculations from a concrete perspective.

This study describes the intellectual ability of a cohort consisting of 120 young women in compulsory care at a SiS institution in Sweden, tested and analyzed between January 2001 and May 2005. The women have been tested with the intelligence tests WISC-III or WAIS-R, as well as the personality trait tests BCT, CMPS and SCL-90, and the personality disorder test SCID-II. This material has been analyzed to investigate how these women's intellectual ability relates to other factors. The analyses show that the main difference between the women of this study and the normal population is their level of intelligence and presence of personality disorders. The IQ level of these women is statistically proven on an average one standard deviation lower than the normal population.

Public libraries have an important roll of making information accessible to all people. This democratic right supports the cultural development in our society. When public libraries build websites offering information and services it can sometimes cause obstacles for impaired users. It is therefore our purpose to evaluate a selection of websites and library plans to examine how the libraries work with accessibility for these users. This thesis is based on theories of cognitive and human computer interaction, and information architecture.

 Abstract The purpose with this study is to study the individual setting of salary rates among branch heads. We have chosen to look deeper into which criteria that are the base for the branch heads? individual setting of wage rates within geriatric care and the care of disabled people. One other aspect we have looked into is how the setting of salary rates appears from a gender perspective. The empirical material in our thesis consists of both qualitative and quantitative methods in the shape of a questionnaire study and three open interviews.

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

A literature study and a field trial have been carried out in order to investigate the physiological response of potato plants to different soil moisture levels. Higher yield, quality and number of tubers can according to the literature be obtained if constant high soil moisture is kept during major parts of the growing season. A field trial was set up where drip irrigation was used as an alternative to conventional irrigation techniques to maintain high and constant soil moisture. The application of water in the drip irrigated area was monitored and adjusted on a daily basis so that the soil moisture stayed as close as possible to the recommended level. The sprinkle irrigated area was irrigated according to traditional practices with approximately 35 mm every 7th to 10th day depending on the whether.

Studies show that the performance of Swedish students in the subject of mathematics is to be considered somewhat average. The government has therefore decided to assist with extended project funding to schools on a local level in order to improve these results.Schools will, unlike before, practice teaching suited for the individual needs of students based on their previous experiences, knowledge level, language comprehension and their environment. This is also clearly stated in the Swedish school curriculum.My survey shows how three teachers in primary school actually work towards individualized teaching of mathematics and what methods they prefer. This survey also answered what these teachers considered to be the obstacles and opportunities with individualized teaching methods. The difference in approach of how to practice this has also been documented.The survey, based on interviews and class observations, have been analyzed and compared to previous research and theories in the field of teaching practices.

This paper examines the impact of the congruence between the background music and the brand image on the customer behaviour in retail store. The essay's hypotheses are built after the famous S-O-R-model that unveils if congruence background music affects the customers' emotions, brand image and response. The aim of the study is mainly to answer if the congruent background music stimuli in the retail store environment will affect the customer's emotions and if it will increase spent time and money. The congruent background music has been selected through two pre-studies based on consumers' brand image. A quantitative study has been conducted where triangulation was applied in a real store environment, where in total 201 surveys was collected for the main study.

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Since criminality started to rise steeply in most western welfare states following the second world war the relationship between welfare support and criminality has been debated. For a period of time thought to be an effective preventive measure against crime welfare support has since from time to time come to be seen by some as ineffective and in some cases even as a contributing factor to the rise in crime. It remains a contested issue as new theories, such as social support theory, which is employed here, attempt to contribute to the understanding of what effects general welfare has on overall crime levels. As a connection which is relatively well-researched in the USA, altough still not yet fully understood, this study strives toward a better understanding by testing the relationship in a swedish context. The relationship might not function in the same way considering that the US is a fundamentally different welfare-regime than Sweden, liberal and social-democratic respectively.Untangling the relationship is attempted by employing a multivariate regressionanalysis on a crosssectional dataset consisting of data from 2012 covering 247 of Swedens total of 290 municipalities.

Introduction: Anxiety and depression are common among patients enrolled in psychiatric outpatient care. Ear Acupuncture is an alternative form of treatment that has been shown to relieve anxiety and depression in previous studies.Aim: To evaluate ear acupuncture as a group treatment for depression and anxietyMethod: A psychiatric outpatient clinic has been offering group treatments with ear acupuncture for anxiety and depression for 5 weeks. Participants of the study have answered self-rating scales Montgomery Åsberg Depression Rating Scale, Beck Anxiety Inventory and Sheehan Disability scale before and after the treatment period. Material was collected in the period 2008-2012 and has been analyzed in SPSS.Results: Data from 31 patients were included in the study. The results from the study showed a significant difference, between the measurements before and after treatment, with a reduction of the average values in the three different scales.Summary: From this study, it is difficult to draw any conclusions about the effect of ear acupuncture.

Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.

Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.

 Tediousness, fear and boredom are all part of everyday?s life for a student. How can a teacher counteract these feelings of boredom and replace them with a feeling of pleasure of learning? Students have to be motivated and want to go to school every day. By comparing student?s experiences of motivation this essays purpose is to create a theory about factors for motivation in education.

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.
