This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .

En brandstation ställer specifika krav på funktionalitet och flöden - som i det här examensarbetet har fått generera rumsligheter och arkitektoniska händelser. Brandbilarna står uppradade i ett stort och rymligt garage. Ljuset flödar in genom portarna och det stora glastaket. Om hundrafemtio år kanske det inryms en konsthall här istället - så som i Magasin 3 en bit bort..

The purpose with this project is to compare different fuels when investing in a central combustion station at a case study farm. I have chosen to write about biofuel from an economical perspective. This because the heating costs are steadily increasing. Also because the farm in this case study has several different heating systems, which are neither profitable nor easy to work with. I have made calculations regarding usage of splinter, wood and grain for the heating system.

        This is a report that describes the entire process of design of a measuring station for rolling resistance. The report is structured with elements of Fredy Olsson's method.The report also includes a brief presentation of HGF, the company that will manufacture the machine. Requirements and preferences are set up and used in a weighting of criteria by which product suggestions are based. These suggestions are used in the evaluation to produce a final draft product. Solutions to major functions are produced by criteria?s. Component selection for all components is performed, a CAD-based model is developed and an economic analysis is set up. FMEA analysis is set up. The report ends with a brief summary, critical review and suggestions for further work..

SAMMANDRAGDenna rapport är en del i ett examensarbete på byggingenjörsutbildningen vid Chalmers Tekniska Högskola. Som komplement till rapporten finns ritningar på idéförslag samt ett program som beskriver byggnadens nutida utformning samt kraven på en ombyggnad.I denna rapport utreder vi möjligheterna att bygga om den befintliga järnvägsstationen i Mellerud till ett modernt resecentrum, på uppdrag av Melleruds kommun. Rapporten behandlar flera olika grundläggande lösningarav utformningen. Med dessa som utgångspunkt utformas sedan de olika delarna i den bästa av de grundläggande lösningarna. Målet med rapporten är att utforma ett resecentrum som tillgodoser resenärernas behov.

The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping. The work is going to answer the questions about today?s throughput time, how much waste that occurs, number of staff at the assembly line, how the supply of material works and possible improvements that can be made at the work stations. The work is also going to give a proposal of improve-ments that can be made.The methods used to get the result include observations and measurements, con-versations with technicians and operators and also data from Fläkt Woods? data-base.Large variations in throughput time are measured during the measure period, from 3 hours up to 5 hours and 35 minutes.

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

Syfte och frågeställningarSyftet är att ta reda på om en utökad undervisning i idrott och hälsa har ett samband på skolelevers motoriska färdigheter. Detta syfte kommer vi undersöka genom att besvara frågorna ?hur ser de motoriska färdigheterna ut hos eleverna i en Bunkefloskola jämfört med i SIH-projektet?? och ?finns det något/några områden inom de motoriska färdigheterna där skillnaderna är särskilt utmärkande??MetodDatainsamlingen bestod av två stycken observationstillfällen där vi observerade 60 elever, från en Bunkefloskola i Sverige. Eleverna uförde NyTidstestet som syftar till att testa deras allsidiga rörelsekompetens. Skolan som eleverna går på arbetar med Bunkeflomodellen som karaktäriseras av att ha fysisk aktivitet på schemat varje skoldag.

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

På Scania väntar stora utmaningar i framtiden. Ständigt ökande konkurrens kräver ständiga förbättringar av produktion och produktionsstruktur. På Chassimonteringen i Södertälje monteras lastbilar samman. Detta examensarbete har utförts på en avdelning på Chassimonteringen där lastbilshytterna förbereds för att monteras på lastbilschassit. På denna avdelning, Hyttförmonteringen eller helt enkelt Förmonteringen, finns stora möjligheter till förbättringar.

The ongoing construction of Kristianstad is a trade mall in the city center, the City Hall and the railway station neighborhood is rebuilding, new residential projects are planned and "The healthy garden", "Accessibility for everyone" and "ERA-farms" are also current. Kristianstad has always a sustainable way of thinking in the background during the development and they are trying to meet all three perspective of sustainability: economical, ecological and social. The municipality seeks knowledge both by sharing their own and takes part in other municipalities in the development process..

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

Wind power is one of the sources of renewable energy which has to be developed further in order to lessen our dependence on non renewable sources of energy. It's mainly oil and coal which have to be replaced by green energy. Wind power is already established in many countries, for example Germany, The United States of America and Denmark but it has to be continually developed and expanded to meet the needs of the growing energy consumption in the world. During the last few years many types of small wind turbines have appeared on the market. These small wind turbines are an alternative to the big wind turbines or power generators which demand huge sums of investment money.A new target group can now buy the small wind turbines in order to cover their own usage of electricity.
