TILT - en serie glas

This work describes a series of glasses, both for people withvisual handicap, and the glasses are not only limited for use onlyby people with poor sight.I have, based on the course Senses, done research and lookedinto how to design glasses for visual handicapped people interms of function, look and expression.I have elaborated with several different glasses and performedmany experiments to come up with my final result, consisting ofa series of glasses.The glasses in the series are made with a weight on one side, onestep on the bottom to get the possibility for the glass to tilt over,which enables you to both hear and see when you have reach acertain amount of substance in the glass.It has also been important for me that the glasses express somethingand get an individual identity.The result became glasses for whiskey, coffee, shots and mullwine..

Smart seed : fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling

Oilseed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.

Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

Skogssådd med tall och gran : effekter av fröegenskaper och skärm/hygge på plantbildning, överlevnad och tillväxt de två första åren efter sådd

Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method. This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.

Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Naturvetenskap i förskolan : Pedagoger om relevans och uppfyllandet av läroplanens naturvetenskapliga mål i förskolan

The main reason for the study was to find out how much naturscience is used in the daily situation in the preschool/school environment with the younger kids. I have studied the teacher`s educations background, if this had any role in the teaching of naturscience. To get my answers I interviewed ten teachers with different teaching background.The result showed that science was present both in the preschool and school for the early years. Everything from teamwork to outdoor play and small experiments. To play out in the woods is most important part teaching in naturscience.My study showed that a teacher`s educations background had no part in the teaching of everyday life in the nature.Keyword: experiment, primary, school, science..

Hur hanteras vildsvinets (Sus scrofa) populationstillväxt i Sverige idag?

The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.

Peltierelement - spillvärme till el : Peltier element - waste heat into electricity

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

Djuromvårdnad vid fång

Laminitis is a common but devastating condition, and affected horses are often euthanized or influenced a very long time. Many horses never return to their original capacity. Laminitis is often associated with severe pain and a long time of convalescence. Symthoms includes lameness, hoof hyperthermia, strenghthened digital pulse and pain. The horse often tries to move the body weight away from the forelegs which are often more severly affected than the hindlimbs.

Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Mineralämnen i fullfoder : studier på 20 mjölkkogårdar i Halland

In 2003 the recommended phosphorus allowance for dairy cows in Sweden was lowered approximately 10 %. For a cow at a production level of 35 kg ECM it decreased from 0,40 to 0,36 % of dry matter. To investigate if the decrease has been implemented at farm level, analysis of following minerals; P, Ca, Mg, K, Na, S, Se, Cu, Mn and Zn was performed on the TMR at 20 farms in Sweden in the summer of 2004. The purpose was to describe the actual allowance of different minerals as compared to the new recommendations. One hypothesis was that the decrease in recommended allowance of phosphorus would lead to the need of new mineral feeds on the market.

Det individuella programmets populäritet: studievägledares perspektiv på elev och program i kommunerna Boden, Luleå, Piteå och Skellefteå

This work of investigation was to report how four study counsellors see upon the facts regarding the amount of admission, the students social surroundings and local designs for the Individual program (IV) at upper secondary school. Through interviews with four professionals set to guide the students at four different schools in the rural districts of Boden, Luleå, Piteå and Skellefteå, this has become a paper that describes how they see these young adults today. Different handicaps and diagnosis, troubles at home, pregnancy and even drug abuse tend to make you wonder how they possibly can get through school at all. Regarding local development within the program there are no strings of what to do but for every district to deside for themselves and this has led to different ?experiments? with students not mentaly fit for school at all.

Betong - Förvånansvärt lättflytande!

Concrete is a very common construction material. It´s characteristics are strength, durability and formablility. Superplasticizer is a common admixture, which changes the properties of concrete. Today (spring 2007) there are no certian mathematical methods to calculate the required percentage of this admixture needed to give the necessary set slump flow in the overall concrete recipe. Concrete batching companies must therefor experiment with different amount of superplasticizer in order to meet the specified slump and strength. The purpose og this report is to investigate if any mathematical relation can be established between the amount of superplasticizer used and the slump flow achieved. After carrying out some practical experiments using four different superplasticizers a direct relationship can be establish between the percentage of admixture used and the slump/flowability achieved. Unfortunatly at present due to the numerous variables, the calculation of mathematical formula can not be achieved..

Conqueror för Indigo

Conqueror for Indigo is production treated with an active chemical to maximize the ink adhesion.ArjoWiggins has found that another chemical, the candidate compound, would improve the propertiesof the paper. ArjoWiggins therefore wish to replace the current compound. To strengthenthe patent requirements for ink adhesion needs to be determined. A theory is developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate.
