Byggnadsinvesteringsbedömning : En studie av 44 svenska kommuner 2011

Syfte: Syftet med studien är att undersöka och presentera vilka investeringskriterier som svenska kommuner använde år 2011 vid byggnadsinvesteringar, samt i vilken utsträckning extern hjälp vid investeringsbedömning och utförande av byggnadsinvesteringar användes.Frågeställning: Vilka samband fanns mellan investeringsandel per omsättning och i hur stor utsträckning beslutade byggnadsinvesteringar blev dyrare än beräknat?Vilka skillnader fanns mellan större och mindre kommuner med hänsyn till investeringsbedömningar i byggnader?I vilken utsträckning förekom samarbete mellan kommuner gällande byggnadsinvesteringar?I hur stor utsträckning anlitades extern hjälp med projektledning och kalkylering vid byggnadsprojekt?Metod: Studien är baserad på en webbenkätundersökning med 44 deltagande kommuner och en personlig intervju. Denna undersökning analyserades och jämfördes sedan med en referensram baserad på sekundära källor.Slutsats: Större kommuner behöver förbättra sina planeringar och kontrollera sina byggnadsinvesteringar i och med att investeringarna ofta är större och fler saker kan gå fel än för mindre kommuner.Fler kommuner borde samarbeta mer vid byggnadsinvesteringar för att på det viset kunna matcha byggföretagen vid upphandling.Kommunerna bör fortsätta kontrollera den externa hjälp de använder vid byggnadsinvesteringar och göra tydliga kontrakt..

Läcksökning med penetrant ? kvalitetssäkring av

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

Överavkastande Aktierekommendationer : En utopi eller en hållbar investeringsstrategi?

Background: The value of stock recommendations have been debated for a century andthe debate has escalated since Alfred Cowles (1933) published his research in ?Can StockMarket Forecasters Forecast?? As of late, savings in stocks has increased and the householdsare managing their savings more actively. The consequence of the increased interestin stocks has resulted in a growing market for stock recommendations. Not just financialmedia but daily newspapers have embraced this new found interest, hence stock recom-mendations can be found in almost all large newspapers in Sweden. Furthermore, this phe-nomenon has also lead to intensified research within stock recommendations.

Orsaker till kolik hos häst

The aim of this work was to investigate possible risk factors for colic in horses, and to describe what horse owners can do to prevent this condition. The gastrointestinal system of the horse is constructed for continuous high fibre consumption for a period up to eighteen hours a day. Under those conditions, the continuous flow of digesta stimulates gut motility so that the intestines move constantly. When the diet is changed rapidly and the horse is being fed high rations of concentrates each day, the risk of getting colic is higher compared to when consuming less concentrates and giving the horse a stable diet. Lack or absence of access to water and restricted allowance to move freely every day increases the risk of colic. Changed management practices and decreased activity contributes to increased risks, as well as other critical risk factors such as breed, season and age combined with rapidly changed management. More knowledge and education is required of the horse owners about feed requirements in the horse, management routines and rapidly changed activity..

Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel

Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol. Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.

IT-system och organisationsutveckling

This report describes work on the thesis ?IT systems and organizational development?. The work is carried out on Stocksbro Energi AB, during spring 2009. The company wanted better flow in their production but also review if the inventory management function located in Visma SPCS Administration 2000, could be used in the organization. Under the first part of this report the system were tested to ensure if the system would work together with the organization.

Container Security Initiative - En diskursanalys utifrån teorier om det il/legala

Container Security Initiative was launched in 2002 by the US Customs and Border Patrol in order to secure the global flow of containers destined for USA. This thesis attempts to analyze Container Security Initiative in relation to a possible future scenario made by the weapons industry where the state's global traderoutes are being subject to militarization. A development which is partly based on the threat posed by global illegal trade. The latter is discussed and defined based on current research made by Carolyn Nordstrom, Moíses Naím and theories on the cosmopolitan perspective made by Ulrich Beck. Strategy documents concerning Container Security Initiative are then analyzed in terms of discourse to try to say something about what the program indicates.

Introduktion till Certifierad Grafisk Produktion på Jernström Offset

The aim for this thesis was to develop a proposal of documentation, containing rules and procedures, which JernströmOffset needs to acquire the Certified Graphic Production certification. A fundamental part was to study the materialissued by Sveriges Grafiska Mediaförening, to clarify the requirements that must be met to obtain the certification. Therecommendations found in the CGP material must also be considered.Based on the requirements and recommendations of Certified Graphic Production, a mapping of the workflows atJernström Offset was performed. It was done by interviewing employees from different departments at the company,this to get a clear understanding of the operations carried out throughout the production flow and the final qualityfollow-up.During our reviewing process we found that a number of changes, in terms of working environment and practices,must be made at the company. As a result of this we propose some appropriate actions to be implemented.The documentation was finally written, through the requirements and recommendations of Certified GraphicProduction and then applied to Jernström Offset?s work procedures..

Rena rör : Clean pipes

In this project a washing station has been constructed for Albany International AB. At present, there is no existing system to clean the dirty pipes that are coming back to the company.The work followed the product development process, and it started with the requirements list. This was followed by brainstorming, evaluation and completion.The result was a concept for de present time and one concept for the future.The present concept is intended to be built immediately. This is an adjustable bench with sliding bearings to facilitate the work. The actual cleaning is done with a high pressure washer that uses hot water.

Utveckling av en ny tillverkningslina

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

Inventering av värmelager för kraftvärmesystem

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

Studie av introduktionen av NorFor Plan för foderstatsberäkning till mjölkkor i Sverige :

NorFor is a cooperative project between the consulting organisations owned by the farmers in the Nordic countries ? Sweden, Norway, Denmark and Iceland. The project started in 2001 and the outcome, the system for ration calculation NorFor Plan and the model for evaluating the ration NorFor Evaluation, was completed in 2006. Along with NorFor Plan economical optimization are available and according to literature, the optimization will generate a 2 öre lower feed cost per kg milk, and thereby improve the profit for the farmer. The use of NorFor Plan in Sweden for feed optimization during spring 2008 has been very small. In this study eight herds in the middle of Sweden fed half the herd according to the classical system used in Sweden and the other half according to NorFor Plan system.

Hållbar växtnäringshantering i Stockholms län : En aktörsanalys

Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.

En kombinerad Organisk Rankinecykel och värmepump integrerat med ett fjärrvärmesystem : Där värme- och elproduktion samt lönsamhet studeras och avfall är huvudbränslet

The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market shares. This Master?s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the fuel mix used in district heating systems, and this share is expected to increase in the future.

Uttryck och intryck : En studie om skillnaderna mellan avsikt och uppfattning på Windows Live Messenger

Face-to-face communication is always complemented with non-verbal signals that give us clues as to how a message shall be interpreted, but as communication is moved online the possibilities to express oneself becomes more limited.This paper focuses on the instant messaging client Windows Live Messenger and three of the non-verbal functions that it provides (nudges, winks and emotes). The purpose of the paper and its underlying study is to compare the senders' intentions with the receivers' conceptions when it comes to these functions.The study was done as a questionnaire with two different versions of the questions, one looking at the senders' intentions and the other at the receivers' conceptions.The results were then compared in order to look for tendencies. The results showed that the most common intention among the senders was also the most common conception among the receivers, but that the rest of the attitudes didn't match at all. The functions that are supposed to help the conversation flow often create ambiguity instead and lead to vagueness, misconceptions and annoyance..
