Småskalig elproduktion i Arvika
Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.
Predation som selektiv kraft bakom differentiering av populationer av sötvattensgråsugga, Asellus aquaticus
Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.
Folkbibliotek och resursfördelning. En jämförande studie av sju folkbibliotek i Uppsala kommun.
Allocation of funds to public libraries is uneven and this study will try to explain the reasons and clarify why the allocations of funds are distributed like they are and what calculations influenced the financial apportionment. This master thesis accounts for allocation in seven public libraries in Uppsala. The study shows that one reason for uneven allocations is demographic. Another reason is that the library has come into a good or bad circle. There are no models for allocation of funds to public libraries in Uppsala, thats why their allocations are given after a percentage increase of earlier years allocations, and that leads to a good or bad circle.
Brand i förorten : En studie av etiken i journalistiken
A great fire seized a suburb in a small town in Sweden in the autumn of 2011. Parts of a shopping mall were burnt to the ground by youngsters. Due to the suburb's earlier problems, the event was a tough ethical dilemma for the town's journalists.The purpose of this thesis was to study and examine the local newspapers ethical treatment of this event. How do they motivate their decisions on what to publish and what not to publish? How do the articles treat ethical dilemmas? What do the journalists think about ethical journalism?This study is based on a survey of the articles published about the fire in the two local newspapers seven days after the fire.
Hur påverkas beteende/känslor och fysiologiska faktorer på människa och häst vid interaktion mellan parterna? :
The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments.
Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.
Studie av planerings- och produktionsprocess i sågverksbranschen
The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.
Vänner med förmåner : positiva effekter av interaktion mellan människa-hund
The aim of this review was to examine scientific literature to determine what kind of physiological and psychological benefits derive from human-dog interaction, as well as attempt to uncover a possible mechanism behind these benefits and whether or not they are mutually beneficial.
A growing body of research indicates there are physiological and psychological benefits associated with human-dog interaction. Significant cardiovascular benefits have been linked with human-dog interaction, as have lowered blood pressure, cortisol and heart rate. Interaction with dogs is often associated with a feeling of social support and well-being, and dogs also seem to facilitate social interaction between people. Dogs? ability to buffer and reduce stress is also well documented.
A strong indication was found regarding a relationship between physical contact and benefits associated with human-dog interaction.
High Cereal Prices : An analysis of the causes behind the increase in the world market price of corn, rice and wheat.
The purpose of this study is to examine which factors played an important role in the food price crisis of 2007-2008. Theories used are Microeconomic theory, explaining changes in supply and demand, and Macroeconomic theory, explaining the impact of changes in exchange rate on prices. A theory regarding speculation is also used to explain the impact of speculative activities effects on price. The method used is multiple regression analysis in order to determine the effects which ethanol production, oil price and dollar exchange rate had on the surge in the price of corn, rice and wheat.The data used is in monthly observations during the period 2005-2008. However, other factors are taken into consideration during the study, such as production quantity, stock size, economic growth, speculative activity and population growth.
Indirekt blodtrycksmätning hos hund och katt :
The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.
Bildförbättring över en bildsekvens
When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
Ett holländskt fenomen i Värmland : Faktorer bakom och effekter av en holländsk inflyttning
AbstractDuring the last five years there has been a considerable immigration from the Netherlands to Värmland in Sweden. INVA, Invest in Värmland, wanted to highlight this phenomenon and therefore contacted Karlstad University to make a survey about how extensive the immigration is and what consequences it brings for the business life and municipalities in Värmland. We were luckily chosen to perform this research and the main focus in this study has been the following questions:? Why do the Dutchmen choose to buy their house in Värmland?? What are the main reasons for leaving the Netherlands?? What consequences does the immigration cause for the business life in Värmland?? How do the Dutchmen experience the contact with Swedish authorities?To answer the questions we designed a questionnaire that was sent to 200 Dutch house purchasers. The ambition was to survey all the Dutch house purchasers in Värmland, but with the time constrains and the municipalities having problem to find complete data, we limited the survey to 200 households.

Care and solicitude about Swedish documentary heritage has varied substantially throughout the years. The main purpose of this essay has been to investigate what efforts have been made to preserve rare book collections at public libraries. These cultural policies have been studied from both a national as well as local perspective. What we have tried to explore can be condensed into three questions: What national initiatives have been taken in the past century to preserve the municipal documentary heritage?What initiatives have been taken in the past century to preserve thedocumentary heritage of what is presently the municipality of Jönköping? What value do rare book collections at public libraries represent? The results indicate few national efforts were initially made to preserve rare book collections in the timeframe we studied.
