This report contains CFD-simulations of cable tray fires in nuclear power plant applications with the CFD-code SMAFS. Furthermore the report evaluates the use of CFD-codes within this kind of problems. The assessment of this report is that there is a tendency towards the good use of CFD-codes but before using it solely more research has to be done on the subject..

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.

When cows in Sweden are inseminated the heat strength is reported to the Swedish milk-recording scheme and AI scheme. Cows that show strong signs of estrus are desirable and the trait is included in the Swedish breeding goal. A strong heat makes it easier to inseminate at the right time and to avoid long and expensive days open. Since ten years the heat strength is scored from one to five by the farmer and reported to the milk-recording scheme and AI scheme. Earlier the score was from one to three and the decision was made by the AI technician.

This thesis work is the result of the company Prisjakt?s wish to develop and improve its current system of opinions for online stores. The challenge was to develop a similar system that competitors are using but better. The collection of information is based on purchases and are collected from Web-shops. The purchases can then be monitored in a control panel.

Ett branschanpassat affärssystem är avsett för organisationer verksamma inom samma bransch. Syftet med denna typ av affärssystem är att ge högre passform än standardiserade affärssystem och vara billigare än skräddarsydda affärssystem. Det råder dock brist på kunskap om hur dessa ska utvecklas. Genom vår litteraturstudie presenteras en kravinsamlingsmodell med utgångspunkt i Requirements Engineering som ska ge stöd för utvecklare vid insamling av krav för branschanpassade affärssystem. Utöver det identifierades ett flertal aktiviteter relaterade till modellen.

During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.

The aim of my bachelor?s thesis is to investigate, through a literature review, changes in the distribution of filamentous algae as well as the general species composition of macroalgae and diatoms in Swedish eelgrass meadows. I have also studied the possibility of tracking these algae and diatoms in eelgrass meadows using eDNA methodology. The focus has been on linking these changes to climate change factors such as eutrophication, temperature increase, and anthropogenic emissions, and how these affect the health of eelgrass meadows and their ecosystem services, such as a carbon sink and biodiversity support. The results show that filamentous algae have increased markedly in coverage in Swedish coastal areas between 1980 and 2021, especially in sheltered bays, indicating that altered environmental conditions favor these fast-growing species. Genetic tracking using eDNA demonstrated that there are functional primers for many species, particularly among brown algae and red algae, whereas green algae require more specific primers due to greater genetic variation.

More than 1000 Swedish Warmblood foals are shown every year at foal inspections which are arranged around the country. Six traits are evaluated at these inspections: type, head-neck-body, correctness of legs, walk, trot and canter. No previous genetic studies have been done on the data from these evaluations. The purpose of this study was to do genetic analyses of the traits which are evaluated at foal inspections. The purpose was also to see if there are any correlations between the results of the foal inspections and the results from the tests of three-year-old horses.

Denna rapport är ett inledande steg mot att förbättra arbetsmiljön för svetsare vid påsvetsning med Uddcomb Metoden i massakokare. Syftet med rapporten är att analysera problemet med värme och dålig luft samt förklara hur och varför problemet uppstår. I arbetet ingår även att ta fram olika lösningar för att slutligen hitta ett komplett system för ventilation och kylning. Den föreslagna lösningen består av ett integrerat kylsystem och ett koncept med mindre fläktar, kallade torpeder, som monteras på arbetsplanen vilka driver ut varm och smutsig luft snabbare ur kokaren. Den föreslagna lösningen utreds även ur ett ekonomiskt perspektiv.

The Swedish beef cattle population is growing when the dairy cattle become fewer. The fertility of the beef cows is important for the profitability in beef cattle production. Today there is no genetic evaluation for female fertility in Swedish beef cows. The purpose of this study was to see if calving interval can be used in the genetic evaluation as a measure of female fertility in beef cows. For this purpose the variation in calving interval for beef cows of different breeds and ages registred in KAP was studied.

Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

The aim of this project is to study the work that has been done by the youth welfare to prevent accidents and to increase the preparedness in case of fire. Further the aim is to develop a basis to improve the interaction between the fire services and the youth welfare. The conclusions that were made during the project can be used to increase the safety of the environment that estates by the youth welfare..

TAT?s Cascades and Kastor are programming languages used to create graphical user interfaces (GUI) for mobile phones. TAT Tutorials is a dynamic, interactive tutorial site for these xml-based programming languages. An editor will be available for download to enhance the learning process..

Genetic parameters for four leg conformation traits in dogs (Canis lupus familiaris) are in this literature review summarized to investigate whether selective breeding could be useful to improve purebred dogs´ health and welfare. The four traits are leg length, leg weakness, hip joint and elbow joint conformation. When summarized, the genetic parameters are compared with genetic parameters affecting in pigs (Sus scrofa). Of the four traits, hip and elbow conformations were mostly studied in dogs. However, these traits were not widely studied in pigs.

The purpose of this study was to compile when and why piglets die during the suckling peri-od. Piglet mortality is an important factor influencing the profitability of piglet production. There are many factors that play a role and interact whit each other. This study summarizes when the piglets die during the suckling period and reasons why the piglets die. The infor-mation given is crushed, illness, management/environmental, genetic influence and piglet birth weight/farrowingprocess.
