Betydelsen av prokainets nedbrytning i plasma vid penicillinchock hos häst :
The use of intramuscular injections of procaine penicillin G (bensylpenicillin procaine) in the horse is now and then associated with acute adverse reactions (penicillin-chock). The etiology is not yet clearly understood, but the theories are several. One possibility is that it can be caused by procaine toxicity. Procaine penicillin G is a salt which is quickly dissolved in plasma. Procaine is then metabolized by plasmaesterases to non-toxic metabolites, p-aminobenzoic acid (PABA) and diethylaminoethanol.
Effect of insulin during oocyte maturation in vitro on bovine early embryo development : partially evaluated by novel fluorescent staining
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.
Career choice:The relationship between personality, state anxiety and the career decidedness among Swedish upper secondary school students
The main purpose of this study was to inquire into personality and the state anxiety in relation to career decidedness scale among students in upper secondary school. The participants were 124 students in three grades and respectively non vocationally oriented classes. The participants were asked to grade themselves on a scale in relation to the statements regarding, state of decidedness for career choice, personality (NEO FFI, Costa & McCrae, 1985. Sweden, Gerontologic Center) and anxiety (AnTI, Wells, 1994). The results showed no significant relationship between personality and state of anxiety that could be connected to the decidedness for career choice.
Ryttarens tygelsignalers inverkan på hästens beteende och trycket i tyglarna
This essay derives from the concern that horses ridden with a bit in their mouth can be subjected to strong pressure from the bit if the horse and rider do not understand each other. The horse's mucosa membrane and the tongue are very sensitive tissues (Cook, 1999; Manfredi, 2005; Oliveira, 2005; Terada, 2006) and the bit can then be a source of pain and discomfort. The training of the horse should therefore always be a step by step process and as the horse develops difficulties are increased. Oliveira (2005) suggested that high demands can be placed on the horse but to be successful in the training it is essential to be content with small progress and reward the slightest desired response from the horse. This corresponds with the principles of operant conditioning with negative reinforcement.
Vetenskap eller pseudovetenskap? : En utvärdering av giltigheten i Poppers kritik gentemot Freuds psykoanalytiska teori på basis av demarkationskriteriet
In this essay I evaluate the legality of Karl Popper?s criticism against psychoanalysis, regarding this theory of Freud?s being pseudoscientific. Popper?s criticism is based on his theory of demarcation in which he states that an empirical theory must be possible to test by observations in order to be, as most important is, hypothetically possible to falsify based on other empirical statements ? often in the form of new found facts that contradict the original statement/theory. In purpose of assessing Popper?s criticism I perform a modified idea analysis, based on a book by Evert Vedung (1977).
Estimering av GPS pålitlighet och GPS/INS fusion
The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning. An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.
XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.
En effektivare habilitering med stöd av webbaserad utbildning. En studie om habiliteringens utbildningsutveckling
The information technology development that has occurred over the past decade has broughtmajor changes into people?s lives. We have gotten used to being constantly connected to theInternet and always having access to information through mobile technology. This has led tochanges in education and more and more courses have become available through Internet. Theseweb-based educations are nowadays very common in schools and in the business world as theyprovide increased flexibility for the user.Habiliteringen Lundbystrand has seen the potential in this kind of education and believes this isan opportunity for them to rationalize their work by replacing parts of their education for parentswith a web-based education.
Skadegörelse klotter nedskräpning förbjuden : Graffitiborttagning som ikonoklasm
This essay concerns graffiti, and in particular graffiti removal regarded as iconoclasm.Graffiti is described as a visual symbol laden with both negative and positive values, and sometimes as a meaningful expression in the urban public space. One problem with graffiti as a field of study is the diversity of both the meaning of the term as well as the diversity of the phenomenon itself. Therefore I have defined the term graffiti as follows: words and images painted on public walls by a person usually in an unauthorised manner. Specific examples of graffiti and related phenomena are presented. Within the Swedish anti-graffiti discourse the pejorative term klotter (scribbling) is used to describe what I above define as graffiti.
"Vi har ju alla en tårtbit i det hela" - en studie om samverkan i arbetet med hedersrelaterat våld och förtryck
This paper deals primarily with the developmental potential and use of court -based mediation in Swedish law, and its relation to court-based conciliation and the judicial procedure as means to end a conflict. In Chapter 42, Section 17 of the Swedish Code of Judicial Procedure, a judge, before the parties have their main hearing, can act as a mediator between the parties to settle the dispute. The judge should, according to the law, always try to make the parties come to an agreement before the main hearing. This obligation can be fulfilled either through the use of court-based conciliation, or court based mediation. Mediation as such is rarely used in Sweden, and one of the goals of this essay is to try to provide a tentative answer to why that might be the case. The second goal is to try to find a consistent, yet flexible notion, of the concept of ?jurisdiction?, and to provide an explanation for the relation between mediation as an alternative method for dispute resolution and the judicial procedure. .
Försök med olika såmaskiner vid konventionell sådd och direktsådd
In this thesis, two studies with different drills were included. In one of the studies two drills were compared: Väderstad Rapid and Väderstad Spirit. In the other study various drills for direct drilling were compared.
The study with Rapid and Spirit was placed in two locations with different autumn tillage; one on ploughed land in Uppsala and one on cultivated land in Västerås, both with relatively high clay content. Rapid drills have a single disc coulter, while the Spirit drills have a double disc coulter. Various aspects were compared such as aggregate distribution, seed placement, emergence, crop yield and economic outcome.

The thesis demonstrates protection solutions that can be suitable for a camp during internationalmissions in order to resist complex threats. The threats could consist of small arms, machineguns,RPG 7, anti armour missiles, mortar, artillery, HPM-weapons, car bombs, biological and chemicalweapons as well as sabotage and theft. It?s not the technology itself that makes the threat scenariocomplex it?s the way the opponent acts during the operations. The opponent acts usually incivilian clothes and therefore he is difficult to distinguish from other civilians.

Accelererat åldrande av produkter Apelsinjuice och hallondryck
Brämhults Juice AB is one of Sweden?s leading producers of fresh fruit juices and drinks. The fruit drinks last 3 days once opened and when stored in a refrigerator kept at 7°C. Since factors that shorten the drinks? best before date are usually not noticed until the entire batch has expired, it would be advantageous to find a way to accelerate the drinks? natural deterioration, so that an unusal short best before date is noticed before more products are shipped off to the stores.
Crowdfunding : Svenskarnas motiv till att investera
The purpose of this essay is to examine the Swedish people?s level of knowledge about crowdfunding and their incentives and deterrents to crowdfunding investments. Early on crowdfunding was divided into two objectives: reward based and equity based crowdfunding. The division of objectives is logical due to the differencing conditions of the motivation for investors to invest. Supported by theories in crowdfunding incentives, commitment-trust, the prospect theory, and the diffusion of innovations, we aim to establish a comprehensive line of reasoning to support our model of motivation in the conclusive chapter.The results of this essay were achieved by a combined method.
