De flesta industrier har någon typ av kylsystem som betjänar industriella processer och komfortkyla. Funktion och effektivitet på systemen varierar och när kylproblematik uppstår på anläggningen kan anledningarna vara flera. Kylproblematiken kan bero på bristande kylkapacitet, felaktigt injusterade köldbärarflöden eller underdimensionering av distributionssystem samt cirkulationspump.Detta examensarbete har utförts i samarbete med Stora Enso Skoghall och syftet med studien är att kartlägga och analysera deras kylsystems kapacitet, både sett till producerad kyleffekt och möjligheter till distribution på anläggningen. Genom en ökad kännedom av systemets funktion kan optimeringsförslag arbetas fram för att minska risken för kylproblematik och kostsam produktionsbegränsning. Då distributionssystemet är äldre och påbyggt i etapper finns misstankar om att det även finns möjligheter att med modern teknik få systemet att bli mer energieffektivt.

Today we are living in a time were impulses from other places and cultures constantly grow and the contact over the boundary is getting bigger. We se satellites pictures over the world, we hear about worldwide ecological problems, we learn about other different lifestyles, we cock food that are inspired from the worlds many kitchens, we shop more and we can travel to different parts of the world. My problem was to find out how cultural phenomenon spreads to a greater extent global and how this transference take place, but also be able to se what factors that has a part in the cultural spread.What I found with help from my literature study was that trough improved communication and transports has gained mobility in the world and people can take part off others culture.The world is shrinking and this means that human beings identity is changing and this create a so-called hybrid mixture. Culture is what we human beings create. Culture can be seen as a community phenomenon for the most parts.

About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.

Outdoor housing of horses? best fulfils the horses? need for physical activity and it is an alternative to the more cost and energy demanding indoor housing in stables. Furthermore, if outdoor housed horses have access to shelter they can generally cope well with adverse weather conditions such as high or low ambient temperature, heavy rain or strong winds. In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather variables (e.g., ambient temperature and wind Speed) and insect harassment. The shelter-seeking behaviour was studied for three different groups of horses: Group 1) eight individually housed horses in paddocks that had access to three different shelter types (C: closed on three sides with roof, R: open on three sides with roof, W: closed on three sides without roof), Group 2) 25 group housed mares with foals on pasture with access to shelters C, and Group 3) ten mares without foals on pasture without access to shelter. Each group was studied for eight days.

In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

Whiplash is a bodily injury, where the person that is injured is subjected to force towards the neck, mainly in traffic accidents. Even low Speed accidents can cause severe damage due to the complicated muscle and nerve structure of the neck. Symptoms range from neck aches and headaches to numb fingers and this makes the Whiplash injury difficult to diagnose. Whiplash is also a treacherous injury due to the fact that the symptoms can not be objectively verified. The principal symptom of the injury is pain, which is to its nature highly subjective.

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

The ability of a dog to perform some kind of practical work, for example hunting or herding, depends among other things on its behavioural characteristics. In animal breeding it is not always easy though to select for behavioural traits. It may, for example, be difficult to identify traits that are not only heritable but also of importance for the dogs' ability to perform the practical work of interest. Moreover, it is often difficult to accomplish accurate measurements of behavioural traits. When selecting dogs for breeding, it is usually preferable to evaluate them using an objective and standardized bahavioural test, rather than results from field trials.

In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production. The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.

Det går allt fortare. Nätjournalister befinner sig mitt i nyhetsflödet. De är bland de första individerna som får ta del av de nyheter som inkommer till en webbredaktion. Från att en nyhet inkommer till en webbredaktion till dess att den publiceras på nätet är en process som idag inte behöver ta mer än tio minuter. Under dessa tio minuter hinner en nätjournalist både att granska källan, kontakta eventuella vittnen, skriva nyheten och sedan publicera den.

At SLU, Divison of Reproduction, Dept of Clinical Science, there is an ongoing project on the development and evaluation of new methods for the assessment of stallion semen quality. This EEF-study, which is a part of that larger project, has focused on the effects on motility and fertility of stallion semen of two different extenders and selection. Both an objective method and a subjective method for analysis have been used and compared in the study. The increase in the use of artificial insemination with cooled semen in Swedish horse breeding over the last decade is thought to play a part in declining foaling rates (Kareskoski et al, 2006, Kuisma et al, 2006). This calls for better evaluation methods of semen quality since cooling and transportation put higher demands on semen quality in order to maintain fertility (Aurich, 2005).

The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.

Byggbranschen ställs inför stora prövningar med högt satta mål inom klimat- och energipolitiken och en omfattande påverkan på naturmiljön till följd av dess stora material- och energiomsättning. Demonstrationsprojekt i byggbranschen anses vara ett viktigt steg i utvecklingen av ny byggteknik, men samtidigt finns det ett gap mellan goda resultat som demonstrationsprojekten kan uppvisa och det traditionella arbetssättet (Femenías, 2004) . Samtidigt som det finns ett behov av satsningar på miljöanpassad nyproduktion, finns det också ett stort behov av god förvaltning av våra befintliga byggnader. Bebyggelsen som helhet förnyas väldigt långsamt; drygt 90 procent av de hus som finns år 2020 är redan byggda (Miljövårdsberedningen, 2004). Byggnaders driftsskede har en betydande del i bygg- och fastighetssektorns miljöpåverkan (Byggsektorns kretsloppsråd, 2001), vilket ställer höga krav på fastighetsbolag och fastighetsförvaltare.Syftet med denna rapport är att belysa fastighetsförvaltarens roll i arbetet mot en hållbar utveckling, men också den eventuella problematik som råder med förvaltning av fastigheter som byggs som miljöprojekt.

SAMMANFATTNING Uppskattningsvis transporteras 171 miljoner grisar inom EU varje år, varav ca 3,5 miljoner i Sverige. Grisarna kommer, under hela förloppet från förflyttningen från box i stallet till bedövningen i slakteriet, att utsättas för stressande moment. Orsakerna är bland annat omgrupperingar, nya miljöer, vibrationer i bilen samt, speciellt under sommaren, värmestress. Temperaturen i djurtransportbilen är en nyckelfaktor som dessutom kan förstärka effekten av andra stressorer. Lastning i höga temperaturer ökar risken för värmestress. Värmestress innebär att djuren får allt svårare att avge sin värme. Även den relativa luftfuktigheten har betydelse, framförallt vid temperaturer över 30°C. Det är ventilationen i transportbilen som ska transportera bort värme och fukt från bilen.
