Torkning och pelletering av organiskt hushållsavfall - en konstruktionslösning

The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.

Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi

AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.

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.

Röstförmedlingen : Att skapa en kreativ designlösning till ett nytt företag

It becomes increasingly more important that, as a new buisness, both to be seen and heard in an increasingly harder competition situation where the range of similar products and services increase. It requires a well planned and well thought visual profile to succesfully stand out on the market. To give a good impression, this profile should be both distinct and aesthetically appealing. In the making of a new profile it requires creativity to succesfully think in new directions and to separate from the competition.This practical report presents the production process for a designsolution to the new website Röstförmedlingen (Voice agency), a commission from the production and commercial bureau Bartos media. The task in this project was to create a graphic profile and a lofi-prototype that would represent Röstförmedlingen as a buissness.

Utvärdering av produktionsledarens användning av Holmen Skogs datorbaserade stödsystem vid operativ planering av avverkning

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

Hur mycket "mjölk" ska det vara i mjölken, och hur styr vi det?

In most countries, the dairy industry focuses on the volume of milk produced instead of its composition. This results in a high content of water and a lower proportion of fat and protein. A high proportion of water is not desirable when processing the milk into various dairy products like cheese, cream and milk powder. High water content also increases the costs for transport and storage, and also an unnecessary, albeit marginal, strains on the world?s water reservoir.

Utredning av alternativa distributionssystem för Holmen Paper

Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

Uppfödning av gyltor till hållbara suggor

Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.

Fel i produktionen : En studie om uppkomna fel i två anläggningsprojekt

AbstractThe purpose of this study was to identify problems that may occur in the execution of a civil engineering project and suggest measures to reduce the risk of errors. The study was conducted in cooperation with a civil engineering company in the Gothenburg area. During two weeks in February 2012, a field study took place on two construction sites where disruption and problems that took more than 15 minutes to correct were noted. During the field study we identified 39 such occurrences in the projects and then these were classified into different categories according to their cause.The two largest categories were "Design" and "Planning", which accounted for half of the errors that were discovered.In the study results were evaluated to decide whether it was possible to detect discrepancies at an earlier stage. The cost to fix an error in the design stage may be significantly less than to correct the problem in production.According to the evaluation, 55% of the errors could have been detected earlier if there was a greater degree of observation for such issues by everyone involved in the project.

?Om dom bara säger nej hela tiden vet man ju inte hurman gör när man ska spela? : En studie om surfplattors användningsområden i förskolan

I have through qualitative interviews and analysis of previous research in the area searched answers to what tablets are used for in preschools and the reason why they are used in this way. In addition, it examines the similarities and differences there are in how teachers and children describe the use of the tool in preschool. The study is also looking for answers on whether and how the plates are used to develop children's scientific knowledge. There are six teachers and 14 children's statement that forms the basis for the analysis. The results indicate that tablets are used for two purposes.

The cow eye-Function and effect of light on milk yield

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.
