Gas som bedövningsmetod vid slakt av slaktkyckling :

Electrical stunning is the method that has been used in Sweden to stun broilers prior to slaughter. However, for reasons of animal welfare and meat quality, research has been made in the EU to develop new stunning methods. Gas stunning is now regarded as the best alternative. In this study literature has been reviewed with focus on different gas stunning systems and observations have been made at two different slaughterhouses regarding animal welfare before, during and directly after stunning. At one slaughter plant carbondioxide was used in a two-stage system where the birds were standing on a conveyer belt during the stunning procedure.

Stadsklimat/Gatuklimat :

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

Kartläggning och analysering av initieringsprocessen : En fallstudie utförd hos Teknikgruppen för RV2012 på Sandvik AB

This thesis has been carried out to the Technology Group at industrial plant Tube Mill2012, which belongs to the Sandvik AB. Technology Group is a unit that takes care ofall requirements and suggestions regarding investigations, test runs and designmodifications. The main objective is to identify and analyze the existing initializationprocess to see where improvement opportunities exist and to come up withsuggestions for improvement, supported by previous research and literature. Anextensive literature search and case study has been conducted to provide a solidfoundation to refer to during the work. Completing the interviews and the workshopgave a clear picture of their unstructured work and approach, how the lowrequirements on the received orders caused problems for the group as well as thelack of a standardized resource allocation method provides major delay factors.Solution proposal then became a very easy process model in five steps with all theinformation gathered in one place.

100 % svenskt foder till mjölkkor :

As for today, a large quantity of protein feeds is imported from other countries to be used in the Swedish dairy production. The main import is soya from Brazil. The soya-production in Brazil results in negative consequences for the natural environment in the area, and the long transport of the feeds requires a lot of energy. The organic dairy production in Sweden is, with the highest probability going to be forced to use 100 % organic feed to the cows in the year 2005, due to new EU-rules. These are some of the causes why there are reasons to look closer at the possibilities to feed Swedish cows with only Swedish feeds. In this study, I have looked at the KRAV-rules for organic feeding, where the goal is feeding with only KRAV-approved feeds.

Optimalt råvarulager för biobränsleföretaget :

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

En man och hans ?pplen: en fallstudie av Carl Str?mbergs ?ppeltr?dg?rd

This bachelor?s thesis studies Carl Str?mbergs ?ppeltr?dg?rd, a private garden consisting of a large number of apple trees and varieties. The garden is located outside ?rebro, in N?rke, and is owned by a unit owner association whose goal is to preserve and determine the varieties. Through interviews, articles, site visits and documents from Carl Str?mberg, the purpose have been to get an understanding of who Carl Str?mberg was, how he collected the apple varieties and how that process was affected by the climate amongst apple growing and pomology during that time.

Composers? and choreographers? world of ideas. Aspects of the art process. This inquiry is about the artistic process when composing contemporary music and choreographing modern dance. I have studied three composers? and three choreographers? thoughts about the artistic process and the work that leads to a piece of music or a dance.

St?ndsg?rdens ?vergivna tr?dg?rd: en studie av Kullen i Hova

The higher status homestead called Kullen is located on top of a small hill just outside of Hova in V?stra G?taland. The house stands on a plateau surrounded by a stonewall. Aerial photos from the 1960?s shows what looks like a big parklike garden behind the house, with a gravel walk cutting through on the length of the garden up to the house.

Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

Fordonsgas ur gödsel och vall

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

Optimering av indunstningsprocess

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

Vilometabolism hos barn och ungdomar med Cerebral Pares : En deskriptiv korrelationsstudie

Background: Cerebral Palsy is usually divided into three subgroups: ataxic, spastic and dyskinetic, where children and adolescents can, because of misestimation in nutrition and energy intake, suffer from weight problems.Aim: To compare calculations with equations with the individual's measured RMR in the subgroups, to see if any equation is more suitable. This could be used as a tool to calculate the resting metabolism at times when it is not possible to perform clinical measurements.Method: The RMR has been measured in 37 children and adolescents aged 3-15 years through indirect respiratory calorimetry. Those values have been compared with calculations from five equations. The results were then analyzed in order to find if any equation is better to apply for calculating resting metabolism for each subgroup.Results: The ataxic group was overestimated by 56.5% of the calculated values. WHO/FAO/UNU?s equation indicates a significantly strong correlation between the measured and calculated values (r=0.85, p<0.05).

Cystocentes versus spontankastad urin : tillförlitlighet vid klinisk diagnostik hos tik

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.
