Fertility is of central interest in the dairy production but has during the last decades declined. Increased milk yield has resulted in high pressure on the metabolism of the dairy cows that are supposed to manage the transition from dry cows to lactating cows within a few weeks around the parturition. Much indicate that metabolism and fertility are closely linked, with insulin playing a substantial part. There are many studies suggesting that the main part of gestation loss can be found during the early embryo development, a period which can be studied in vitro. The aim of this study was to test the effect of insulin during maturation in vitro and to evaluate two different fluorescent stainings on oocytes and embryos; a nuclear stain and a staining of apoptotic cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-method. Bovine cumulus-oocyte-complexes (n=991) were aspirated from abattoir-derived ovaries.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

The purpose of this study is to investigate ethnic discrimination in the recruitment process. National and international law protect individuals from ethnic discrimination by potential employers during the recruitment process.Despite the laws in place to protect human rights, minorities in society do not have the same opportunities in the labor market as the rest of the population. Minorities continue to have difficulties compared to Swedish nationals in the recruiting process. Highly educated immigrants seeking employment in Sweden continue to report being treated unfairly based on their ethnic background.Ethnic discrimination in the recruiting process is based on prejudice and stereotypes that affect decisions whether it is visible or hidden, intentional or unintentional.Under the law, it is not legal to base a decision on prejudices or stereotypes. Therefore, it is important for the employer to highlight the job requirements to ensure the recruitment process is ethical.

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

The treatment that women get from health care staff can influence the experience of the abortion and how women manage to coping the experience emotionally. The aim of this study was to illuminate women?s experiences in connection with an abortion. The findings show that the women?s social situation led them to the decision of abortion.

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Då det köptes in ny utrustning för kalibrering av värmestrålningsmätare till SP, Brandteknik, fanns det ett önskemål om att effektivisera proceduren vid kalibreringen. Vid kalibrering med den befintliga hård- och mjukvaran finns många manuella moment som skulle kunna reduceras.I detta projekt har ett styrprogram utvecklats i programmeringsspråket LabVIEW. Programmet använder ett seriellt kommunikationsprotokoll för att styra den kontroller som reglerar temperaturen i kalibreringsugnen. Programmet ställer in de temperaturnivåer som ska ingå i kalibreringen, upp till tio stycken, och kontrollerar när temperaturen har stabiliserat sig. När den gjort det tas ett antal mätpunkter ut och sparas till en resultatfil.

Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.

This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.

The aim of the study was to examine plaqueindex, gingivalindex and oral hygiene measure among patients between 20-26 years of age, who were treated at the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a dental record. All 126 subjects with records in this age were including in the study. Sixteen records (13 %) were excluded because the criteria were not fulfilled. Plauqeindex, gingivalindex and oral hygiene measures were registered from 110 records.

Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.

During the 19th century the Elementary school and its teachers emerge in the city of Halmstad and in the parish of Veinge as well as in Sweden overall. The aim of the essay is to enthrone these teachers? conditions and a comparison is done between the teachers in these two places. The mate-rial that is used is for example minutes from the board of education in Veinge and the city council of Halmstad, collected works about the elementary school of Halmstad as well as litera-ture regarding the subject. The essay starts with a short background history about the Elementary school and its teachers.

Aim: My aim with this study is to investigate whether the co-workers in the company Arla Foods is satisfied with the communication between the company and the employees. If there are any changes to be made or if it works well as it is now.Method: I have sent out invistigationforms to 85 co-workers within Arla Foods. This forms included questions about Arla Foods internal communication and how the co-workers apprehend this. I have also made 7 interviews over the phone with co-workers on the dairys around Sweden. Including in these 7 interviews have I also talked and posed questions to representatives for the trades-union within Arla Foods.

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

I wanted to focus this essay on the operative?s perspective of running religious organizations in the city of Karlstad and to see positive and negative aspects of their day-to-day life working with their organization, following up with a comparison of the difference and the similarities between those groups. After delimitating which groups I was going to examine, I implemented a qualitative study of four people, from two different religious groups, whom I performed interviews with. My method of performing these interviews and understanding the perspective of the informants, I had a semi structured interview guide along with a recent study that was opting for similar conclusions, only in a different county and with different input perspective. The result of my study showed a difference in establishment of their region but with a lot of similarities in problems with their religious and structural premises.
