During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

This thesis examines a project that has been conducted at a software development company. The aim is to investigate which problems firms of this kind faces performing projects. We choose a theoretical frame consisting of a modern view on how to manage projects. The view argues that the management of each project has to be adapted to the situation at hand. This theory is divided into two separate streams of reasoning; one emphasize learning, delegation of responsibility and flexibility, while the other argues for control, time planning and the importance of keeping to the plans.When we compare the theories to the case we draw three main conclusions: A thorough phase of investigation is required to produce the necessary planning documents.

How does a corporation work during the recruitment phase to entice and motivate younger members to work for their organization?The aim is to examine in which grade corporations and organizations? recruitment needs to adapt to encounter Generation Y on the labour market.The base in our method is abduction and our research is based on a qualitative method. We have fulfilled interviews with corporations such as Scania, Skatteverket, Swedbank and Appelqvist & Ottoson HR AB.Corporations need in a sense change their recruitment and emphasis their resources to sell the whole corporation and its image to the young job applicant. The younger members demand a total impression of the corporation to implement an interest and to get motivated to work there. Together with our respondents we have realized that Generation Y has higher demands on their workplace than earlier generations..

The objectives of this study was to (1) examine Swedish professional bowlers understanding of imagery (2) their experience in imagery (3) see if there was interest in improved use of imagery within bowling. Twelve professional bowling players (M = 30.42), all male, took part in the study. Six of the players were ranked among the best in the world. The instrument that was used was The Individual Profile of Imagery Experiences in Sport (IPIES, Weibull 2008). The result showed that eleven of twelve use imagery within bowling.

This study will focus on the role of social services and their experiences regarding why youth become involved in criminal activities, as well as the preventive measures social services offer to address this issue. The paper employs the theories of territorial stigmatization, systems theory, and labeling theory (of deviant behavior). The study is based on a qualitative method. Semi-structured interviews were conducted with social workers who have experience working with youth involved in criminal activities or at risk of involvement. The results indicate that a lack of social cohesion can be a contributing factor to youth involvement in crime, and various factors can lead individuals to such situations.

This report describes the work and the results found when comparing three different 3d modeler applications. The programs are 3ds Max, Maya and Cinema 4D. The comparisons focus on the possibilities/the amount of freedom these programs interface offer to its plugins. The comparisons are made from the point of view of a tool for creating animations developed as a plugin for these modelers. This plugins demands on the system it is loaded into have been analyzed and from the results of this analysis a template have been created.

This thesis examines the everyday resistance, and its interaction with cultural hybridity, of the Saami population in the administrative unit of Torne lappmark during the period 1639?1732. To do this, the thesis uses theoretical concept of everday resistance as it has been described by JamesC. Scott and the theories of cultural hybridity as they have been described by Peter Burke. Primary source material used in this thesis consists of the court records from Torne lappmark, specifically from the courts at Jukkasjärvi and Enontekis.The results of this thesis present a picture of the everyday resistance in early modern Torne lappmark.

This essay is a historiographical analysis of the picture of the transition period between the Bronze and the Iron Ages in Greece presented in A. M. Snodgrass' The Dark Age of Greece and V. R. d'A.

The purpose of this study is to examine discursive change regarding mathematics and language in the Swedish primary school curriculums. The study analyzes pedagogical discourses represented within the curriculums and how they represent different pedagogical theories in relation to discursive and social practice. The analysis shows a change towards a more language oriented curriculum discourse in mathematics which still carries an intertextual and discursive heritage from the prior curriculums. In relation to the early curriculums of the Swedish primary schools the former explicit differentiation of students becomes implicit as the language skills become of increasingly importance..

The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.

The objective with this essay was to compare the modern epistolary novel Priority by danish author Iselin C. Hermann with the epistolary genre during its heyday in late seventeenth to early nineteenth century. I especially looked at gender: the similarities and differences between the female character in Priority and the female characters during the epistolary novels days of glory. I concluded that Priority has the same structure, characteristics as the heyday epistolary novel and that the female character does not have any typical similarities with its stereotypical female characters. In addition I also came to the conclusion that she is reminiscent to their original model Héloïse and follows the epistolary novels heyday convention when she dies at the end of the novel..

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea?s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task.The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument.

Syftet med detta arbete är att ta reda på om läxor ger fördjupad kunskap inom ett ämne. Vidare vill vi veta vad syftet med läxor är. Vi har genomfört femton intervjuer, jämt fördelade mellan lärare, elever och föräldrar. Resultatet pekar på att läxor behövs, men att eleverna vill ha en annan typ av hemuppgifter än de i nuläget har. Vi genomförde även mindre studie på sex av våra egna barn för att få veta hur mycket tid de trodde sig lägga på sina läxor och hur lång tid de i verkligheten ägnade åt läxläsning. Vår slutsats är att om läxor ges, ska de vara väl genomtänkta och att det kan skapas utrymme för att göra läxorna under skoldagen. Nyckelord: läxor, kreativitet, individ, variation.
