Effekten av ett probiotikum i en besättning med hög incidens spädgrisdiarré

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

Påverkan av skuggor från vindkraftverk

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Sensorfusion för undervattensrobot i kärnteknisk miljö med Kalman filtrering

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

Val av produktion vid generationsskifte :

The objective of this thesis was to get more knowledge before an alternation of generations. In theses I have chose to make two drawings, one for dairy cows and one for cattle rearing. The drawings are made for a future alternation of generations at my parental home in the province Dalarna. The results are made out of educational visits at different farms and literature investigations. Those dairy farms who I visited had different milking system at each farm and the cattle farm I visited had beef production. The farms are placed in the middle and south of Sweden. At 1998 the Swedish Board of Agriculture decided to change the stall breadth and stall length and the result of this is that many farmers had to rebuild their cattle- and dairy buildings or end farming..

Folkbiblioteks och släktforskarföreningars stöd i släktforskares egen forskning sett ur ett självstudieperspektiv

The purpose of this thesis is, from a self directed learning perspective, to investigate the support of public libraries and genealogy associations of genealogists' own research, i.e. their search for ancestors as well as their possibilities to broaden their history outlook. Accordingly, five public librarians and five genealogy representatives in the west of Sweden have been interviewed regarding the support that can be offered to genealogists. The investigated support to genealogists in their own research is about working environment, literature and material, activities and the cooperation between public libraries and genealogy associations. In this thesis conclusions are merely drawn from a self-directed learning perspective, a perspective where also different forms of support are being recommended by scientists.
