Motivationsfaktorers relevans för medarbetarna på Sörmlands sparbank Vingåker : En kvalitativ studie
Bakgrund: I takt med att konsumenters preferenser har förändrats, har företag fått överge massproduktion till förmån för produktionssystem som bättre avspeglar konsumenternas ökade krav på flexibilitet. Ett sätt för att överbrygga denna utmaning är att implementera lean production. Även om detta sätt att producera på har tydliga fördelar för dagens företag, verkar lean production även kunna medföra problem i avseende på att kombinera med den befintliga, i många fall, traditionella styrningen i företaget. En del av styrningen som verkar vara speciellt svår att kombinera med implementeringen av lean production rör mätningen av produktionen. Vid en närmare granskning visar det sig att det råder vissa motsättningar mellan traditionell mätning och lean production som kan påverka företagets beslutsfattande negativt.
Statusbedömning av asynkronmotorer
Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..
Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus
The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.

My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.
Optimering av SNCR-system i en biobränsleeldad panna : möjligheter till minskade NOx-utsläpp för ENA Energi
Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.
Brikettillverkning på gårdsnivå :
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.
Ekonomi i vallfrödominerad växtföljd :
This is a project about how you grow timothy seed and red clover seed successfully. The main part is about economic analyse to see if it is any economy by growing leyseed.
There are lots of things to be aware of to get all the costs in your economic analyze.
Timothy
Timothy seed is planted on 4400 hectares in Sweden. It is possible to grow timothy seed in the south part of Sweden. Timothy is very sensitive for dry weather in spring and in the beginning to summer. Timothy gives acceptable harvest of seed for about three years.
Red clover
Red clover is also sensitive for dry weather and is suitable to grow in the south part of Sweden.
Civila musikkårer i landskapet Värmlands bruksorter : Betydelsen av faktorerna ekonomi, rekrytering, musik och kulturskolan, samt samverkan med studieförbunden för musikkårernas överlevnad
This bachelor thesis is about civilian marching bands in the province Värmland industrial communities, with a focus on Degerfors, Edsvalla, Gruvön, Nors, Slottsbron, and Vålberg bands. Degerfors, Gruvön, and Slottsbron bands are three corps that still operates concerts and performances. The other three unions are defunct.In Värmland, there were many mills that were operating well into the 1900s, roughly speaking there were about 25 mills in various industrial areas. These mills had operations in glass, iron, and paper, each user had a band at least a brass sextet and today there are only eight bands left in Värmland. Bofors in Karlskoga, Charlottenberg, Degerfors, Dejefors, Gruvöns in Grums, Hagfors, Skoghall, and Slottsbron bands.What is the reason that so many bands have disappeared? To answer the question I have investigated the importance of four factors have had for the unions: finance, recruitment collaboration with the music and arts, as well as cooperation with educational associations.The results show a marked reduction in civil bands, from about 25 corps to eight corps today.
Från vilda till domesticerade djur - kan man gå ett steg längre?
Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.
The Value of Relationships in a Chinese-Western Business-to-Business Context: An Investigation on Relationship Bonds, Adaptation, Trust and Commitment
The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.
Dexametasons effekt på trombocytaggregering och syreradikalproduktion
Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.
Beräkningsmodul för ett förbättrat offertförfarande och minskad icke-värdeskapande tid
In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

One interview is also made with a city planner.
Lammproduktionens ekonomiska påverkan av MTR :
The Swedish consumption of lamb a increasing, and today we yearly eat a kilo of lamb per person each year. As a consequence the Swedish degree of self production according to lamb is steadily decreasing, and is today about 39 %.Today Swedish Meats is now cooperating with the Swedish lamb breeders organisation to raise that percentage. At the same time the European Union presents a new agricultural reform, the MTR (Mid Term Review). The shape of this new reform is not yet fully known, but the general policy has been more or less outlined. The new reform is split into three propositions: the farm model, the regional model and the mixed model.
