Valutasäkringar och räntebindningar inom lantbruket : åtgärder för att förbättra ekonomin inom lantbruksföretag
The thesis aims to investigate the farmer?s perception of currency hedging and interest
rate bonds and to investigate the farm size of companies categorized by number of acres,
has no effect on this. The work also aims to gain an insight into what active farmers
consider to be important what to consider when they choosing a bank and a personal
banker.
The work is based on the survey and has been supplemented by a literature review on the
subject. For the survey were selected out randomly 50 farmers with Agriculture and
Rural Management education.
The requirement of the farmers was that they should be farmers by profession, and also
made sure that the farmers of various sizes came with. We got a total of 32 responses
within the set response time we said, which was better response than we expected.
When the final result came we ranged the farms in a size range.
We found out that all farmers in the study diligently follow the market and are easy to
assimilate new ideas, providing opportunities to profitability of their business with the
different instruments that are available on both the financial level and farm level.
The investigation revealed that the major in favor of having a personal banker.
They think it´s good to have a special plug to turn to who has knowledge and experience
of how the agriculture sector operates.
KRAV-grisar har fler ledanmärkningar än konventionellt uppfödda grisar.
Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.
Modellering av reserv- och nödkraftsystem i JAS 39 Gripen
Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.
Intelligenta Switchar
This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.
Barns tankar om vattnets kretslopp och vattnets betydelse för livet på jorden.
Huvudsyftet var att ta reda på vad förskolebarn kan och tänker kring vattnets kretslopp och vattnets betydelse för allt liv på jorden. Samtidigt syftade undersökningen till att ta reda på pedagogernas arbetssätt och tankar kring dem. Undersökningen har genomförts med hjälp av kvalitativa intervjuer med såväl pedagoger som barn. Intervjuerna har spelats in och sedan transkribetats för att därefter analyseras. Resultatet av undersökningen visar att barnen har god kännedom om vattnets kretslopp och vattnets betydelse för livet på jorden.
Temperaturzoner för lagring av värmeenergi i cirkulärt borrhålsfält
The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.
The role and genetic control of non-coding RNAs in bacterial infection

Effekten av mjölkkors rang på ?antistresshormonet? oxytocin, mjölkavkastning, mjölkflöden och besökstider i mjölkningsenheten i ett automatiskt mjölkningssystem :
The study was carried out at the Kungsängen Research Centre, Department of Animal Nutrition and Management, Swedish University of Agriculture Sciences, Uppsala.
The technical development in dairy production has resulted in a housing system where feeding and milking is done automatically without human contact, a so called automatic milking system. The motives for utilising an automatic milking system, is to increase the animal welfare and to decrease the need for manual labour. However, the system does involve a change for the animals, among the effects is the deprival or the diminishment of a chance for synchronous behaviour and the animals have to agree among themselves in which order they use the feeding stations and the milking unit itself. How and if this affects the animals well-being and production is yet to be solved. A possible way to form an opinion on this, is to study the animals ranking order along with hormone profiles and production.
The purpose of this work was to study the effect of low- vs.
The effect of cold stratification on germination in 28 cultural relict plant species : with the purpose of establishing germination protocols
Cultural relict plant species from the Nordic countries have been collected by the Nordic Genetic Resource Center (NordGen) for the purpose of conservation. To ensure high seed vitality in store, regular germination tests need to be conducted. It is important to get a correct viability status, but the knowledge of seed dormancy in the cultural relict plants is often poor. The objective of this study was to investigate how seed dormancy is affected by cold stratification. The study includes 31 accessions from 28 species with the purpose of establishing germination protocols.
Jämförande studie av normal ERG-svar hos tre olika hundraser :
The purpose of this study was to compare normal electroretinographies (ERGs) from three different canine breeds in order to evaluate if there were any marked similarities or differences between these breeds as to ERG responses. It is known that healthy dogs from different breeds but also dogs within the same breed but in different age categories may have different appearances of their ERG responses. This may be a problem when evaluating if an ERG is normal or not from a dog within a breed not previously examined. Because of this it is important to obtain normal values for each breed and age group in order to be able to use these for later comparisons of ERGs obtained from individuals affected with various retinal diseases.
In this study we have chosen to examine dogs within the three breeds: Labrador Retriever (LR), English Springer Spaniel (ESS) and Chinese Crested Dog (CCD). All of these breeds may be affected with hereditary retinal diseases such as Progressive Retinal Atrophy (PRA).
It is possible that ERG-responses vary due to a number of different factors.
Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos
This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
Översyn av vattenskyddsföreskrifter med tillhörande vattenskyddsområde i Hallstahammars kommun. : Vilka revideringsbehov finns?
Water is an important food and an important natural resource. In order to protect these are the Environmental Code and the EU directive given to water protection and related water protection regulations will be established for all water sources until 2010. Those who will prepare a water protection and related water protection regulations is the municipality or person responsible for water supply. The person then decides and declares the area as water protection and related water protection regulations are municipal or provincial government. The idea of creating a water protection is to protect the water supply and the body of water against pollution caused by point sources, diffuse sources and accidents combined.
Minimizing acts of violence through telephone-linked care: an
automated telephone system for outpatients in forensic
psychiatric care
Achievements within the fields of computer- and telecommunication technology have led to a revolution when it comes to managing information. These achievements have made it possible to offer new services in healthcare, especially in telemedicine. New technology has become a complement to traditional care, thus partly compensating for insufficient time and resources. Telephone Linked Care (TLC) is a telecommunication technology that enables automated dialog counselling and monitoring of patients in their homes. During the last two decades numerous randomized controlled studies with TLC have demonstrated improvement among outpatients with chronic and health behaviour disorders.
Framtagning av en rörväxlaretill sopsugsystem
The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.
