Phenotyping of Bali cattle and interviewing farmers in Indonesia - a minor field study
Among the Indigenous cattle breeds in Indonesia, the Bali cattle is the most preferred by small farmers. The Bali cattle is a beef breed, and is considered to have several advantageous characteristics and to be well adapted to the country?s harsh environmental tropical conditions with drought and rain. The main aim of this project was to phenotype of Bali cattle from different locations in order to identify and document diversity within the Bali cattle breed based on their observable characteristics, to compare cattle from different areas and production systems to see the effect of management on phenotype. In this study, 107 cows and bulls of the breed Bali cattle, from Kalimantan, Sumatra, Lombok and Bali were phenotyped.
Välfärdsregimer och hälsa - en litteraturstudie om determinanter på makronivå
Introduction: Public health researchers have long been focusing on investigating health inpopulations through determinants such as income inequalities. Nevertheless, incomeinequalities can be considered an effect of the organization of welfare regimes. The publichealth status is largely affected by the organization of welfare regimes and consequently thereare large differences in health within and between welfare regimes. How are these differencesdistributed and how can they be explained?Aim: To compare health between welfare state regimes with the use of Esping-Andersen?swelfare regime typology and to investigate the relationship between welfare statedeterminants and health.Methods: A literary review based on 12 scientific articles.
Fallstudie av 10 skånska gårdar för en lönsam stutproduktion :
During the summer of 2005 a number of steer producers in Skåne, Sweden, found that their animals graded less favourable according to the EUROP carcass grading system when slaughtered, than ordinary. The aim with this project was to determine factors that affects the production result in steer production and to find the reason to the lower classification. The project was initiated by Anita Persson, LRF, Skåne and was preformed with supervision from Ingemar Olsson, SLU, and Jens Fjelkner, Skånesemin. Ten producers of dairy steers located in Skåne was chosen for this study. The producers were interviewed to collect information about their steer production with respect to their planning and results.
Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage
When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Local poultry production in rural Zambia and the effect of light on poultry performance
Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production.
Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.
Vilken information får hundägare i samband med kastrering av sin hanhund?
BACKGROUND
Until 1988, it was forbidden to neuter male dogs in Sweden without a veterinary medical cause, so there is clearly no long tradition of this procedure in healthy dogs. According to the website of The Swedish Kennel Club (SKK), February 11, 2011, there has been an increase of castrated male dogs in Sweden. They see this increase as worrying, especially in cases of the less common breeds, where it is most important to maintain the gene pool. The SKK expresses concern that castration is used as a tool to influence the personality of dogs, instead of training and education of the dog. They write that castration should be preceded by a discussion initiated by the veterinarian, where the pros and cons of castration are weighed against each other.

Differences in host plant preferences and olfactory physiology between populations of the moth Spodoptera littoralis established in Egypt and Benin
This study was made to compare and distinguish any differences in olfactory recognition and
host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The
populations used were established in Egypt and Benin, Africa. The documentation consisted of
information about (1) each of the strains development through the larval stage up to pupation on
diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton,
clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any
possible responses to plant volatiles.
Throughout the diet experiments the larvae from the Benin strain showed significantly a better
development between artificial, clover, cowpea and cotton respectively, while the Egypt strain
had significance between artificial, cotton and cowpea/clover as diet.
Also noted was how the strains substantial development of weight differentiated if fed the cotton
diet, followed by the cowpea diet showing that the Benin strain would develop a higher body
mass on a cotton diet as well as on a cowpea diet.
This trend was however switched once the pupal stage was reached, where the Egyptian strain
contained a significantly greater body mass than the Benin strain on the artificial and the Benin
strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly
better on cowpea while the Egypt strain develops better on an artificial diet.
During the oviposition experiment that both stains showed a clear difference in hierarchy of host
plants considered suitable for oviposition, where the Egyptian strain is significantly more
attracted to clover than the Benin strain.
Also showed with electroantennographic recordings and significant values was the higher
sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate,
Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

Optimering av sintrade kugghjul
Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.
