Horses are by nature herbivores, specialized on grass, and graze during the main part of the day. The horse has neither changed this basic behaviour nor the function of gastro-intestinal tract, when the horse was domesticated by man. A horse on pasture has an even production of saliva and gastric acids. The buffering effect of the saliva makes the pH in the stomach above four throughout most of the day. With abnormal long breaks of eating, the pH may decrease, causing an increased risk of gastric ulcer.

Problem Vad är grunden till att ett företag outsourcar vissa delar av sin verksamhet? Är skälen rent ekonomiska eller finns det andra faktorer som väger tyngre? Vad vill företagen ha av sina leverantörer? Vilka konsekvenser uppstår och hur hanteras de? Syfte Syftet med uppsatsen är att ur ett ledningsperspektiv belysa orsakerna till outsourcing samt de konsekvenser som förenas med outsourcing. Syftet är vidare att belysa det köpande företagets syn på leverantörsförhållandet och hur köparen utövar kontroll över den outsourcade verksamheten. Metod Uppsatsen bygger på sju intervjuer som är fördelade på de fyra fallföretagen Akzo Nobel, Pilkington, Trelleborg Wheel Systems och Tetra Pak. Våra intervjupersoner ingår i företagens ledning eller har tjänster nära ledningen.

Today automatic milking systems (AMS) are growing in popularity. In these systems the cows are loose and have to get to the robot and the feed on their own. The cows ranking in this system affect their welfare. In this study data from seven years in an AMS was used and analysed. The aim was to investigate how ranking could affect the behaviour of the cows at milking and at feeding.

This two years master?s thesis is about book circles for children, arranged by the public libraries in Sweden. The purpose is to gain knowledge about how children experience their participation in book circles, and how they experience their own reading. It focuses on children aged 10 to 12 years, and their leisure reading. The research questions are: What are the book circles? function for the participants? How and why do the children read? What kind of literature do they like? Do the children experience that their reading has developed through their participation in the book circles? What parts of the reading process do the book circles influence?The theoretical framework is threefold.

Syftet med studien är att få en ökad kunskap om vad som motiverar elever i årskurs fem i lärarledda lärandesituationer. Valet att utföra studien i årskurs fem beror på att vi under vår studietid har mött elever i denna årskurs och har ställt oss undrande till vad det är som motiverar dem. Motivation är ett begrepp som har genomsyrat lärarutbildningen och på grund av detta ville vi veta mer om hur eleverna uppfattar begreppet. Flera teoretiker menar att elevers motivation till lärande kan påverkas av såväl inre som yttre faktorer samt diverse behov. Jenner (2004) anser att det även finns en tredje faktor där eleverna tycks pendla mellan faktorerna.

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Obese horses with insulin resistance are often also afflicted with laminitis. Horses with these symptoms are given the diagnosis equine metabolic syndrome (EMS). Signs of insulin resistance are excessive accumulation of adipose tissue on the neck, around the withers and on the dorsal area of the hindquarters. Insulin resistance means that the function of insulin is defective and does not stimulate glucose uptake by the cells in the body in the correct way. This will result in an increased insulin release.

The purpose of this study is to show which content that is most common in the Swedish News Agency TT Nyhetsbyrån?s sports coverage. It also shows if the coverage is concentrated to for example any special sports, clubs, people or topics.This study uses a quantitative content analysis and the result is based on texts from 28 systematically selected days during one year. In total, the study includes 906 texts.The result of this study shows that the sports content of TT Nyhetsbyrån?s news feed is mainly concentrated to two sports, football/soccer and ice hockey.

Bedömning är en central del av lärares och elevers vardag och i den svenska skolan tillämpas mål- och kriterierelaterad bedömning. Om bedömningen kan leda till mer än bara ett betyg, och vägleda eleverna i deras sökande efter kunskap, sägs bedömningen ha ett formativt syfte. En förutsättning för detta är effektiv feedback som kan hjälpa eleven att jämföra sin prestation med kriterierna och själv engagera sig i handlingar som leder till ökad kunskap. Syftet med detta arbete är, att som fallstudie, undersöka hur feedback ges, upplevs och används i en studieverkstad i matematik på komvux. Resultatet av observationerna visar att vanligt förekommande feedback var att lärarna preciserade vad de studerande skulle förbättra eller att de gav beröm. Intervjuerna visar att den feedback som ges uppfattas positivt av de studerande och de använder den antingen för att korrigera fel eller som något som peppar och uppmuntrar dem.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Examensarbetet har genomförts i samarbete med Meritor HVS AB i Lindesberg som tillverkar fram- och bakhjulsaxlar till buss- och lastbilsindustrin. Projektet behandlar de fixturer som används vid transport av bakhjulsaxlar. Målet med arbetet var att utveckla en ny transportfixtur som passar majoriteten av deras bakaxelmodeller och som förebygger skador vid transport.Projektet har genomförts enligt metodiken systematisk konstruktion som beskrivs enligt Johannesson, Persson och Petterssons (2004). Systematisk konstruktion kan delas in i fem steg: produktspecificering, konceptgenerering, utvärdering och val av koncept, detaljkonstruktion samt slutkonstruktion.De problem som Meritor har med transportfixturerna är att de i hög grad slits och att skyddsbeläggningarna inte håller. Det finns för projektet 30 aktuella bakaxelmodeller som skall kunna transporteras med samma fixtur.

Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.

The comprehensive goal in this study was to examine important factors in an introduction of a new machine team. The aim was to identify what elements should be part of an introduction program for new machine team. The examination was done together with Stora Enso Skog. A new machine team and their supervisors where analyzed during a six month period. The evaluation was done with open interviews of the team members and their supervisors. The main question was what should be included in an introduction program to develop a successful machine team as effective as possible? Interviews of the new team and analyses gave good indications how the procedure should be done.

At present, the Swedish pig industry is in transition. Prices have been low, but feed prices have increased. Therefore, many pig producers have stopped their production. Producers that lack an integrated production may contract piglet?s producers, or may use the mediation services that slaughterhouses provide.
