Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.

The aim of this study is to investigate the prevalence of computer consumption among boys in ninth grade, and to see if there were any differences with regards to physical activity, sleeping habits, breakfast habits and BMI. The study has cross sectional design with a comparative and a quantitative structure and is based on a former study called ?Food & Health 2007?.  The respondents were represented by 181 boys in ninth grade, recruited from ten different schools in the county of Uppsala, who were answering questions about media consumption, breakfast habits, physical activity and sleeping habits. Daily computer consumption was reported up to one hour for 12 % of the respondents, one to three hours for 65 % and over three hours for 42 %. The boys who had a high physical activity level were less frequent in computer consumption while those who had a low physical activity level spent more time by the computer.

This work is about euthanasia and how to use it on horses, dogs and cats. A description for each animal is done, about when it is time, why, which methods can be used and who is allowed to use them, how and where it shall be done. The methods we have concentrated on are: - Chemical destruction and the most common drugs for euthanatize horses, dogs and cats. - Physical disruption of the brain activity by a captive bolt, only for horses. The captive bolt only makes the horse unconscious and must always be followed by cutting off the vena jugularis. Then the horse dies because of loss of blood. No matter which method used for euthanizing, the animal must be declared to be dead by the operator before other measures. The testing criteria for death: muscle relaxation and cyanosis, cessation of reflex activity and pupillary dilatation, cessation of respiratory activity and cessation of all cardiac activity.

The probiotic bacteria Lactobacillus reuteri DSM17938 was evaluated as a starter culture in cheese production, with the intention to produce a new interesting product within the functional food market. Growth and acidification rate in milk subjected to different heat treatments, as well as supplementation with growth promoting factors or support cultures was measured during controlled fermentations. The results showed that the weak proteolytic activity of L. reuteri could be compensated for by supplementation with 1% casamino acids or 5% MRS broth. Furthermore, a decrease in growth and acidification rate could be seen when using yoghurt culture or Lactobacillus delbrueckii as adjunct cultures.

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.

In today's society, the internet is an important part of everyday life. Over recent years the number of electronic services has increased markedly. Communities such as Facebook, consume more of people's time than 5-10 years ago. How can public authorities benefit from these communities or are the municipalities not ready for this? The municipalities determine how their resources should be allocated based on the municipality's needs.

This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

Bakgrund Mat- och måltidsituationen på äldreboenden är ett område som ofta diskuteras. Det är viktigt att inhämta kunskap om de äldres näringsintag, upplevelse av matsituationen och åsikter om smaken på maten för att bättre kunna möta deras behov och genomföra förbättringar på detta område.Syfte Syftet med studien var att undersöka mat och måltid på äldreboende. Fokus lades på de äldres smakupplevelse, måltidssituation samt näringsintag.Metod Dels en kvalitativ studie där halvstrukturerade intervjuer användes som datainsamlingsmetod och analyserades med kvalitativ innehållsanalys, dels en kvantitativ studie där den kvantitativa analysen genomfördes med hjälp av Dietist XP samt bilddokumentering.Resultat Den kvalitativa analysen resulterade i två kategorier: uppfattningen om maten och upplevelsen av måltidsmiljön. Nutritionsscreeningen visade att anpassning hade gjorts för dem som hade ätproblem. Näringsintaget visade att de äldre, med vissa undantag, uppnådde det rekommenderade intaget för måltiderna.Slutsats Genom att tänka på hur maten serveras kan aptiten påverkas, vilket i sin tur kan göra att de äldre får ett bra näringsintag.

Hittills har nästan allt färskt kött, som sålts i Ica-butiker, styckats och paketerats i butikerna. Köttavdelningen hos de flesta Ica-butikerna har länge tampats med dålig lönsamhet, främst beroende på stort svinn och höga arbetskostnader. För att ändra på detta upprättade Ica tillsammans med Hilton Food Group (HFG) en anläggning i Västerås, där färskt kött finstyckas och paketeras, innan det levereras till merparten av landets Ica-handlare. Under hösten 2004 fick en del butiker sina första leveranser av så kallat kpk (konsumentpackat kött). Ica och HFG är intresserade av att se hur väl projektet slagit igenom. Denna studie är en uppföljning av projektet, och det syftar till att utreda hur lönsamheten i butikernas köttavdelning har ändrats sedan butikerna övergått till Icas kpk, samt utreda vad skillnaderna mellan butikernas lönsamhet beror på. Det empiriska materialet har insamlats genom att fyra Ica Supermarketbutiker och en Maxibutik i mellersta Sverige lämnat siffror om försäljning och kostnader i köttavdelningen. Data avser oktober - december 2004 och jämförs med samma variabler från motsvarande period 2003. Även intervjuer med butikspersonal har gjorts för att få en uppfattning om hur arbetssättet skiljer sig mellan butikerna. Studien bygger på transaktionskostnadsteorin, som förklarar hur Ica, HFG och Ica-butikerna genom vertikal integration kan undvika onödigt kostsamma transaktioner. Transaktionskostnadernas bestämningsfaktorer tillämpas på den situation, som Ica-butikerna hamnat i sedan företaget övergick att sälja Icas kpk. Precis som Ica hade förutsagt minskade butikernas kostnader vid övergången till Icas kpk.

This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.

The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.

Barn i åldrarna 4-9 år har tydliga önskemål kring hur de vill att deras restaurangbesök ska se ut. I samarbete med Barnens Bästa Bord har en kvalitativ studie gjorts med fokus på barns önskemål vid restaurangbesök. Syftet med uppsatsen var att undersöka barnens önskemål när de går på restaurang med hänsyn till hela måltidsupplevelsen gällande mat, miljö, meny och bemötande. Metoderna som har använts är bildövning där barn har ritat sin favoriträtt, fokusgruppintervjuer med barn samt enkätundersökningar med föräldrar.Resultatet visar att gemenskapen inom familjen är viktig för barnen vid restaurangmåltiden. Barnen är medvetna om att vid restaurangbesök önskas lugn och ro, dock är stillasittande ett problem för barnen.

This study aims to evaluate the waste management in Norrbottens municipalities in key areas such as possibilities to reach the two national waste goals, information to the public, the effect of legislation, future of waste management and differences in geographic- and demographic areas. The Waste Framework Directive (WFD) issued by the EU and incorporated into Swedish law plays a major part in waste management by defining a hierarchy in five steps how waste should be treated. Interviews conducted with each of the fourteen municipalities aimed to find out what step in the hierarchy they are at and what effect the implementation of EU-legislature into Swedish law has had. Based on the interviews a diverse range of answers was found in relation to the questions asked, generally the more populated municipalities saw a more positive future of waste management, mainly because more developed infrastructure to handle waste is already in place. However the smaller the municipality is the harder it is to allocate resources for waste management and problems arise in the form of expensive transports of waste.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

The Swedish market for vehicle inspection is re-regulated since June 2010. More than four years after the re-regulation there are eight companies in the market. Two of these companies are a result of the former monopolist's owners divided the business among themselves. The remaining six companies have entered the market through acquisitions or by building up their business from scratch, these are known as new entrants in the study. The competition has developed slowly and the former monopolist still has the highest market share.
