Working horses in developing countries are mostly used for transportation. They are often owned by people with limited economical resources and lack of knowledge about how to take care of the horses and due to this the horses often suffer from problems such as dehydration, poor body condition, lesions and parasitic infections. The aim of this master thesis was to investigate if free veterinary care improved the health and hydration status of working horses in Nicaragua and it was performed as a part of a project called ?Free veterinary assistance for working horses and training of their owners as veterinary promoters in the Pacific coast of Nicaragua?. Five parameters were used to investigate whether free care improved the health of working horses in six towns along the Pacific Coast of Nicaragua.

Arbetet som utförts består av två applikationer där båda presenterar information geografiskt på internet. Applikationerna har konstruerats i utvecklingsverktyget Visual Basic och med GIS-programvarorna MapObjects och MapObjects Internet Map Server. Den första applikationen som tillverkades är helt HTML-baserad (HTML är ett språk som används för att konstruera sidor på internet), vilket betyder att den fungerar som vilken sida som helst på internet, bortsett från att den kräver att en kartserver alltid har igång kartan i applikationen. Den andra har konstruerats med ActiveX. ActiveX är ett tilläggsprogram som fungerar tillsammans flera utvecklingsverktyg bl.a.

SAMMANFATTNINGMastit är den vanligaste och mest kostsamma sjukdomen hos mjölkkor. Enligt statistik från Svensk Mjölk har cirka 65 % av alla kor i Sverige mastit någon gång under en laktation. Subklinisk (utan märkbara symtom) mastit utgör det största problemet. De är svåra att upptäcka då även mjölken ser normal ut, vilket resulterar i att den hamnar i tanken och levereras till mejeriet. Mjölk från kor med mastit har ett ökat celltal samt försämrad kvalitet och sammansättning vilket i slutändan medför sämre betalt för lantbrukaren.

Background: About five percent of the infants being born in Sweden are cared for in a neonatal unit because of their prematurity. Breastfeeding and breast milk is considered to be the best nutrition for infants in general and for premature infants in particular. The premature infant, depending on how premature, may not be able to breastfeed effectively due to their immaturity. Stress, anxiety and fatigue are factors that affect breast milk production in a negative direction and these feelings are common in the neonatal unit.Aim: To illuminate mothers? experiences of breastfeeding the premature infant in the neonatal unit.Method: A literature review of eight studies with a qualitative research approach, published between the year 2000 and 2012 was conducted.

In the spring of 2006 we had our first outbreak of avian influenza of highly pathogenic H5N1 (HPAI) among wild birds in Sweden. This disease have impact on poultry industries world wide. Sporadically the virus infects other species than birds and we now know it can even cause fatal infection of humans. There are not yet any confirmed cases of transmission of the disease between humans though a suspected case in an Indonesian family is under investigation. If a mutation occurs that changes the pathogenicity and host affinity to humans we are at a risk of a new pandemia, perhaps like the Spanish flu in 1918-1920.

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

Protein i foder utnyttjas av idisslaren via upptag av mikrobprotein i tunntarmen eller som foderprotein som passerat vommen vidare till tunntarmen. Olika råproteinnivåer i foder till idisslare påverkar både miljön och djurens avkastning. Råprotein från vallväxter kan analytiskt delas upp i olika fraktioner utefter var i idisslaren det bryts ned och kan tillgodogöras. Ett sådant system är The Cornell Net Carbohydrate and Protein System (CNCPS) vilket delar in protein i fraktionerna A, B och C utefter deras nedbrytningshastighet i vommen. Många olika faktorer kan påverka halt och sammansättning av råprotein i vallfoder.

Automatic milking systems (AMS) have been in commercial use since 1992 and have since 1998 increased a lot. The objective of this study has been to examine the development of udder health on farms converting to AMS. The study also included a comparison of how udder health developed depending on how farms handled cows with mastitis. This was because farms choose to either milk cows with mastitis in a separate barn or in the milking robot. Other studies on udder health on commercial farms have shown that somatic cell count increases both among individual cows and in the bulk milk when converting to an AMS. No differences between before and after converting to AMS in the proportion of cows treated for mastitis can be found in the literature.

In this study I have compared two systems of handling TMR, self-propelled/ self loading mixers and conventional towed mixers, what has been investigated is the time for filling, mixing and feeding TMR as well as maintenance and fuel consumption. The background of this study is the structural rationalization within the Swedish milk production that has put focus on efficiency and reducing of costs. Forage and labour are the two biggest costs in milk production today. The study has been performed by visiting three farms and with a stopwatch measured the times for filling, mixing and feeding TMR. At the time for the visits, the users have been interviewed regarding maintenance and fuel consumption. They have also had an opportunity to give comments of how they experience the mixers. The result of the study after processing is that the average stock in the study can save 74000 SEK a year by reducing time for filling, mixing and feeding TMR to cows with a self propelled/ self loading mixer . The conclusion I can make of this study is that it?s not the size of the stock that decides whether it?s interesting to invest in a self propelled/ self loading mixer, but the presumptions on the farms, for instance forage logistics and mechanical equipment..

The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..

In this essay i argue that there are three different variables that may be able to control the outcome of certain foreign policy choices. These three variables are External Threats, government division and public opinion. The Essay also tries to identify former president Bush motives behind the 2003 Iraqi War. It is partly argued that the three variables had a certain amount of influence on Bush decision making process. But the main focus lies on the motives behind the attack.

Portable is a project with its starting point in plastic bags, how they negatively affect our planet and how people´s patterns of behavior and qualities of life are affected when people try to live more envi¬ronmentally friendly. Now we have reached the point when peoples way of living and consuming in the western world has to change. This is nothing new and we can now see that sustainability is start¬ing to get attention in every area.Today plastic bags are used on average for 12 minutes. Only one out of 200 is reused, and then only once . This is not sustainable at all.

Idiopathic pulmonary fibrosis (IPF) is a chronic respiratory disease with an estimated incidence of 3-6 cases per 100 000 inhabitants in Sweden. There is no cure for the disease, which inevitably leads to death. A similar disease has been found among terrier dogs, with an especially high prevalence in the West Highland White Terrier (WHWT). Dogs with pulmonary fibrosis become lethargic with exercise intolerance, and in some cases they develop cough and respiratory distress. This thesis gives a brief review of the field of pulmonary fibrosis and presents a method for analyzing surfactant proteins in bronchoalveolar lavage (BAL) in the dog.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.
