Methane emission from nitrate-treated tannin rich feed for cattle in Vietnam
In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.
Cykelparkering i stadsmiljö : en redogörelse för cykelparkeringens komponenter
In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.
Spillningsinventering för bestämning av älgbetesbelastning på ungskog
In the 1980?s the moose population in Sweden grew explosively due to big changes in the silviculture with clear cuttings instead of single-tree selection. Clear cuttings brought big areas of young forest and therefore a lot of fodder in one place. Since this change, the discussion about how to manage the moose population has grown into a very big problem. Forest owners think that the population needs to be strongly reduced because of all the damage that is done to the young forest when the moose seeks its food, and the economic losses because of that.
Historiska Bakverk vol. II - ett arbete om bakverk ur ett historiskt, kulturellt och estetiskt perspektiv
?Historiska Bakverk? is a project about different pastries from a historiacal perspective.The goal was to create illustrations and typography inspired by differentpastries, in order to communicate something about their history and what layunderneath. The project aimed to highlight, understand and acknowlage thepastries as an important part of our history and cultural heritage. Importantquestions I have dealt with throughout the project was in what way the pastriestell us about our history, how it has changed them through time. The result, aseries of posters for croissant, doughnut and pretzel, are a combination of boththeir history and my own experience of them.
Dietary fibre composition and sensory analysis of heat treated wheat and rye bran
When grains of wheat and rye are conventionally milled, large quantities of bran classified as by-products are left and are mainly used for animal feed. Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. It would also be valuable for the food industry to convert by-products as bran to products with higher commercial values.
The aim of this thesis was to analyse the content and composition of dietary fibre of heat treated wheat and rye bran according to the Uppsala method with some modifications in order to analyse soluble and insoluble dietary fibre separately. Half of the bran samples were precooked, dried and roasted and the other half dried and roasted (uncooked).
Den moderna matens uttryck : en etnologisk studie om modernitet i Husmoderns Köksalmanack
The aim of this study is to point out different aspects of modernity in the cookbook Husmoderns Köksalmanack. It is a publication that has been published annually since 1933. The books have been studied in the light of Anthony Giddens´ theoretical perspective on modernity. The study is based on three different themes that all can be linked to modernity. These themes are; Time and space, Locally, regionally and globally, and Advice.
Vilka faktorer påverkar konsumentens benägenhet att välja ekologiskt producerad mat?
Syftet med denna uppsats var att belysa vilka faktorer som påverkar konsumentens benägenhet att välja ekologiskt producerad mat. En surveyundersökning gjordes bland konsumenter i Stockholm och Luleå. Vår studie visade att den ekologiska matkonsumenten är hälsomedveten, lojal mot vissa ekologiska märken och anser även att ekologisk mat är bättre för hälsan. Studien visade även att det ekologiska konsumentköpbeteendet påverkas av konsumentens attityder och värderingar om ekologiskt producerad mat. .
Tidsstudier i kalvuppfödning :
Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf.
To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.
Rättssäkerhet i barnavårdsutredningar : BBIC - ett nytt sätt att arbeta i socialtjänsten
AbstractThe Swedish National Board of Health and Welfare has since a year or so started to introduce a new way to work with childcare investigations within the social services. This new concept, BBIC, is meant to put the child?s needs in the first room rather than the grownup?s as it used to be before. This study is about to examine how BBIC affects the legal security of the children within these childcare investigations.BBIC was first developed in England after a massive criticism against the way that the foster home- and institutional care was handled. In Sweden, BBIC was first tested and developed into Swedish conditions in a few project municipalities for about five years but is now being introduced all over the country.
Bagaren och biblioteket : Skolbibliotekets roll i undervisningen i karaktärsämnena på ett yrkesinriktat gymnasieprogram
In Swedish school library research, the role of the school library has seldom been studied in a subject-specific context. When it has been, the subject has usually been a theoretical subject such as Swedish or Social studies. The purpose of this master's thesis is to study what role or roles the school library can play in a different context, in the program-specific subjects at a trade oriented program in the Swedish upper secondary school, and to determine what factors affect the possibility for the school library to play a role in such a context. The Food Programme was selected as the specific program to be studied. In this program, the students learn a trade, in this case bakery, and the teaching in the program-specific subjects can be expected to be practical in nature.
Hjälp utifrån? Vem behöver inte det? : Om chefers möjlighet att balansera karriär med familjeliv
This study focuses on the internal marketing and how it affects the complaints by companies? communication control. Our purpose with this subject is to increase the understanding of which components affects the relation between internal marketing, communication control and complaints. We have chosen the subject, internal marketing because it caught our interest in an earlier course. On the basis of the literature of costumer complaint there have not been so much research about it and that is why we have chosen this perspective on internal marketing.This study is based on a qualitative approach.
Design comparison between HiperLAN/2 and IEEE802.11a services
This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.
Olfactory responses of the parasitic wasp, Trybliographa rapae (Hymenoptera: Figitidae)
Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges.
The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.
Skadlig kod och sårbarheter i Windows : En studie i virusens historia och nutidens olika säkerhetsrisker
I dag kan man oftast läsa om olika säkerhetshot och risker en datoranvändare måste tänka på för att inte ge någon utomstående möjlighet att komma åt känslig och/eller privat information. Här talas det om nya virus och nya typer av trojaner som sprids som epidemier över Internet, och i bland handlar det om ett spionprogram som följer med en nedladdad fil. Det är svårt att hålla reda på alla typer av skadlig kod som nämns fast med ökad förståelse ökar också chanserna för att klara sig från smitta. Det har visat sig att utvecklingen av skadlig kod är lika stark som den inom kommersiella mjukvaror. Från persondatorns uppkomst i början av 80-talet och fram till i dag, har utveckling skett i alla områden av den skadliga kod det handlar om strategi, syfte och framförallt ren kodkomplexitet.Dagens ledande leverantör av operativsystem och webbläsare, Microsoft, lovar allt mer sofistikerade säkerhetslösningar varje gång en ny version av ett program släpps.
