This thesis project has been written and accomplished in cooperation with HABO AB. The objective of the project was to develop a standard stated packaging system. The background to this is that HABO is not pleased with the system currently in use. The system which HABO is currently using consists of to many sizes. The largest benefit of a standard stated system is that it becomes much easier to organize the packaging with the aid of a computer program.

Mulesing is a surgical husbandry procedure performed on lambs in Australia. The reason is toprevent severe fly-strike to the breech area, which otherwise risks to be soiled with faeces.This problem is mainly occurring in sheep of the Merino breed. Their fine wool is in demandworldwide due to high quality. Mulesing has been performed since the 1930?s, and eventhough alternative methods have been discussed nothing is yet generally accepted.

In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

The logistic business Svenska Retursystem AB was founded by the Swedish retail sector in the year 2000, and their introduction of a grey plastic crate to the supply chain for perishable goods changed the situation for the swedish horticultural sector. The new system revealed several challenges to be tackled by all actors, from the small family firm to the bigger organisations. Whereas the initiative comes from the customer himself, from the horticultural sector ?s point of view, a refusal of the new packing is a hard decision to take. It is however interesting that a comparison between the two systems, shows in favour of the corrugated board boxes, not only concerning environmental aspects but also for economical and ergonomical reasons.

I dagens läge har energifrågorna väckt ett stort intresse i samhället. Nu fokuseras det mer på att bygga energisnålare hus. En betydande faktor som påverkar energiförbrukningen i våra hus är köldbryggor. De uppstår då ett material med dålig värmeisolering bryter igenom ett material med bättre värmeisolering. Köldbryggor är nästan omöjligt att undvika, dock går alltid att reducera.

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

Minskad efterfrågan på traditionella produkter från skogsindustrin kombinerat med ökad efterfrågan på icke-fossila material medför att företag inom skogsbranschen alltmer intresserar sig för nya produktsegment. Holmen New Business Development, en forsknings- och utvecklingsavdelning inom företaget Holmen arbetar med att utveckla produkter där trä kan ersätta traditionella alternativ. En möjlig produkt för avdelningen är Wood Plastic Composite (WPC), ett material som består av en kombination av en plastmatris och ett träbaserat fyllnadsmaterial som kan ges olika egenskaper vilka skiljer sig från rena trä- och plastmaterial. Syftet med denna studie var att undersöka hur designers och produktutvecklare inom olika svenska branscher ser på användandet och utvecklingen av WPC inom sina produktområden, både idag och i framtiden. För att undersöka detta har 18 kvalitativa intervjuer genomförts med företag inom möbel-, köks-, fönster-, dörr-, staket- och trallindustrin. Studien visar att ett lågt pris, hög beständighet mot till exempel röta, fukt och mögel samt att materialet går att bearbeta på samma sätt som trä är de mest önskvärda attributen hos framtida WPC-material. Miljövänlighet hos produkten är ett attribut som respondenterna tror kommer få större betydelse i framtiden men som kunderna inte är beredda att betala för idag.

Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.

Today most dosages used in horse medicine are based on studies in adult horses. Since there are differences between adult and neonatal horses with respect to different pharmacological parameters this can cause problems when administring drugs to neonatal foals. Neonatal sepsis is a common cause of morbidity and mortality in foals and aggressive antibiotic treatment is needed immediately when sepsis is suspected. In Sweden the combination of trimethoprim/sulphadiazine and bensylpenicillin is often used as the initial treatment. When administering drugs, interactions can occur between the drugs and endogenous substances.

Kronisk exacerbativ uveit (ERU) är en av de vanligare ögonsjukdomarna hos häst och drabbar hästnäringen svårt. Det är idag accepterat att sjukdomen är immunologiskt medierad och syftet med denna litteraturstudie är att klargöra de immunologiska mekanismer som ligger bakom sjukdomsförloppet. Detta genom att utreda vad som inducerar uveit och hur återfall av uveit uppkommer samt de autoimmuna mekanismer som är aktiva vid sjukdomen. Grundbulten i ett friskt öga är dess upprätthållande av ett immunprivilegium då en inflammation skulle kunna förstöra strukturer som inte kan repareras igen. Om de barriärer som upprätthåller ögats immunstatus bryts tillåts immunförsvarceller nå ögats strukturer, något som observeras vid ERU.

There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes. District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption Research), which has focused on climate adaption in the Nordic countries.

Lately the popularity to keep different species of dwarf hamsters has increased in Sweden. The requirements of the Swedish legislation to keep hamsters as pets are low which could be a reason for the increasing popularity. Hamsters are in nature generally nocturnal and can travel far distances to find food sources during their active part of the day. Their eyesight is poor, but is compensated by their well-developed hearing and olfaction. ?Run about balls? are made of plastic and the hamster is placed inside it where after the ball is placed on the floor and the hamster can then run protected outside the cage.

?Halmstads Fastighets AB? is a local real estate company investing in sustainable development. One problem though is that the domestic waste, particularly the source separation, at the three resident blocks for students? isn´t working very well. This creates inconveniences for people and environment as well as decreasing the impression on the estates.This project has had the ambition to improve the domestic waste and increase the amount of source separation at HFAB´s student hostels.

The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands. There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.

Couch grass (Elymus repens (L.) Gould) is a severe weed in Sweden, and since both the use of herbicides and cultivation should be decreased, it will become increasingly problematic to control couch. The present work is meant to, by literature studies and an experiment, give some answers to the question if cutting and competition can depress the growth of couch. The experiment was carried out in the growing season 2001 at Ultuna, Uppsala, in plastic boxes. The design was three-factorial randomised complete blocks. The factors were plant combination, nitrogen level and cutting strategy.
