A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.

Den här studien undersöker hur vinstvarningar påverkar stora och små företag. För att förklara dess påverkan på företagen har den effektiva marknadshypotesen och behavioral finance använts som grund. Avgränsningen har gjorts till Stockholmsbörsen då inga tidigare studier haft fokus på den. Empirin visar att företag i Large Cap påverkas med i snitt -4,63% och företagen i Small Cap med -8,42%. Large Cap visade signifikanta abnorma avkastningar under eventdatumet och dagen efter medan Small Cap endast visade signifikans under eventdatumet.

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

The aim of this paperisto find out which plants the Cistercian monks might have cultivated in Sweden during the Middle Ages and which types of plants it would have been practical to grow inside or outside of the Cistercian monastery precinct. Archaeologicaland archaeobotanical studies have been consulted to find out which plants were available in Sweden during the Middle Ages. Examples, mainly from Scandinavia, but also from the continent, are used to show that the monasteries were large institutionsthat had to feed a large number of people and that there would not have been enough space to cultivate everything needed within the monastery precinct.Secondary sources have in the main been used to gather this information, except in the case of the Swedish monastery of Nydala where F-Topo, a database developed by the County Museum of Jönköping,has been used to analyse the amount of land and the types of properties owned by the monastery.The conclusion is that for practical reasons the monks would have cultivated plants that needed to be close at hand, that were rare or delicate, that could not be stored for long periods and that were used in small quantities within the monastery precinct. This would include medicinal plants, herbs for cooking and some vegetables like lettuce, spinach,and similar,that do not keep well. Most other items, grains, cabbages, root vegetables, peas and beans could equally well be cultivated outside the walls.

Abstract: The purpose of this study was to examine the Swedish industry- and craftmanship trade, specifically the relationship between effort and reward and how it affects the meaningfulness during labour hours. Also, what are the possible effects on production efficiency as a whole? Discussed and analyzed through empirics and previous research.38 workers filled out a survey and two interviews were conducted to get a more analytic depth to the data.The results showed that there is little to no reward for high effort during labour hours on the evaluated workplaces, combined with low commitment and meaningfullness. My conclusions are that more ways of effort-based rewards would likely have a positive effect on meaningfulness and thereby the production as a whole. I also show that the theses of Karl Marx are still plausible and relevant in modern day industrial- and craftsmanship trades in capitalist countries..

Because society?s demand for quality, efficiency at low cost is constantly increasing, companies are increasingly choosing to invest new methods to achieve these points. Those who manage to find ways to improve their processes are often the companies that have the greatest chance of becoming a winning player in the market. BIM is a new method that can reduce the internal costs while increasing communications between different parties. However there is disagreement about what BIM is and its purpose.

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.

Quality assurance of construction projects and create effective ways of working, is intoday's pressed position, major objectives for building contractor companies. This thesis is an attempt to see if it is possible to achieve these goals with the new modern tool iPad.The author of this thesis has during the latter half of his one year practice work in Uppsala for the Swedish building construction company NCC Construction Sverige AB, conducted a study on the possibility of using the iPad on an construction site. This has been done with active field studies in which applications have been tested and also the supervisors receptive. The usability of the iPad has always been in focus since it is important that the applications are easy to use and easy to learn.The results of the work, as presented in this report, points at opportunities in efficiency if the iPad is introduced and used on construction site. There are many useful applications for the iPad, and with a system that can handle the synchronization between the iPad and the computer, the workflow will be streamlined significantly..

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.

The values politicians relate with public administration are likely to affect the way that they want the public administration to be organised. The purpose of this study is therefore to examine which values Swedish parliamentary parties relate with public administration and more particularly how they emphasise these values.The study is conducted as an analysis of theoretically relevant bills that the government party and the parliamentary parties have introduced to the Riksdag, and reports and statements of opinion from the parliamentary committees. The documents are from the Riksdag´s sessions from 2000/01 to 2005/06. After examining the documents the conclusion can be drawn that the value that is most emphasised during the period is legal security. This might mean that legal security will have more influence on the decisions taken about the organisation of Swedish public administration..

This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.

Milk yield levels in dairy cows are influenced by many factors such as nutrition, breed, health status, management and environment. This study was conducted among small scale farmers in Zambia, where the climate can be dry for up to six months per year and cause a lack of green pasture for livestock and on-farm produced feed. The purpose of this study was to identify management factors that can influence milk yield at small scale dairy farms in Zambia, and present advice that could improve productivity, without the need of expensive investments. The study included semi-structured questionnaires presented to the farmers (n=29) including questions about cattle management and milk production. Testing of somatic cell count (SCC) with DCC (DeLaval Cell Counter) from herd milk samples (n=56) and observation of housing and animal body condition on-farm was also made.

Lower urinary tract diseases are a common problem in cats all over the world. The symptoms are for example dysuria, pollakuria, stranguria, periuria and hematuria. In approximately two thirds of these cats the underlying cause is not known and the disease is therefore called feline idiopathic cystitis (FIC). We need to know more about the disease to get a consistently effective treatment and prevention. A retrospective study was performed in 50 cats with symptoms of FIC and where other causes of inflammation were ruled out. Data like breed, age, sex, body weight, feeding, therapy and therapeutic results were collected, also if it was an indoor or outdoor cat, duration of the symptoms, if there was any stress and if the cat was living with another cat.

Stunning of pigs at slaughter constitutes of primarily two methods; carbon dioxide and electricity. Both methods have advantages and disadvantages from an animal welfare point of view. The purpose of this study is to compare different methods of stunning pigs from a welfare point of view. Questions included in the study are 1) What differences are there, from an animal welfare point of view, between CO2 and electricity as methods for stunning pigs? 2) What alternatives are there to the methods currently in use? 3) Which method for stunning pigs is preferable from an animal welfare point of view?This report is a literature review.
