Riskfaktorer för Staphylococcus aureus i mjölk och på has hos mjölkkor :
Mastitis is the most common disease of dairy cows. Mastitis can be painful for the dairy cow and causes economical losses for the farmer. These losses are due to decreased milk production, more working hours for the farmer, treatment costs and possible costs due to culling of the cow. The udder inflammation, mastitis, is often caused by bacteria infection. One of the most common bacteria found to cause mastitis in Sweden is Staphylococcus aureus (S.
Implementering av höghastighetsgränssnitt i 0,15 µm halvledarprocess
This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.
Informationssystem för service av truckar och städmaskiner
This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.
Följdeffekter av olika användningssätt för vedråvara : en ekonomisk studie
Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased.
As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.
Förskolebarn i grupp : Grupprocesser i förskolan
Sammanfattning:Syfte och frågeställningarSyftet med denna undersökning är att undersöka vilka material/ hjälpmedel som används för att hjälpa barnen med koncentrationssvårigheter i förskolorna och att undersöka vilka för- och nackdelar pedagogerna ser med materialet/ hjälpmedel.MetodFör att undersöka vilka material/verktyg som finns i verksamheterna gjordes en webbenkät.Webbenkäten korsanalyserades med en intervju som gjordes i en särskoleverksamhet.ResultatResultatet av enkäten visade att pedagogerna använde olika färdiga material samt egenutvecklat material. Det positiva som framkom var att alla barn oavsett behov gynnades av att arbeta med materialet. Det negativa var att pedagogerna ansåg att de hade för lite schemalagd tid att leta efter passande material.Betydelse för läraryrketMin förhoppning är att denna undersökning ska hjälpa pedagoger i förskoleverksamheter med att lättare kunna söka passande material till barngrupperna. Min förhoppning är också att ge pedagoger en liten fingervisning om var de kan finna information gällande hjälpmedel för barn med behov..
Prognostisering av aktieavkastningar med hjälp av makroekonomiska variabler - en svensk studie
Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.
Finns det potential att införa en massdatabas för handel och utbyte av överskottsmassor i Eskilstuna?
In Eskilstuna and Sweden in general the level of reuse of surplus material containing soils and rocks from excavation is low. In this report the potential for increasing the reuse of excavated material in Eskilstuna by using a web-based earth information database has been examined. The purpose of a web-based earth information database is to connect those who have surplus material with those who need material for a fast and simple transaction. The intention is to give Eskilstuna a more environmentally and economically efficient handling of surplus material by increasing the level of reuse and thereby reducing the amount of surplus material that is wasted and emissions given off to the atmosphere during transportation. The potential has been examined in two different ways, by tracing information about a number of projects to see if excavated material driven to the dump could have been used in another project and by interviewing eight of the work leaders active in Eskilstuna.

Kulturella och ekonomiska överväganden för framtiden : En fältstudie om syriska flyktingar i jordanska värdsamhällen
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.
Fuktproblem i sydöstra Asien
The author has, with the help of AK Consultancy Indoor Air AB, formed a series of questions regarding moisture problems in buildings and how these are handled in extreme climates with high temperatures and a high relative humidity. Furthermore to analyse and indentify key material that makes a construction safe against moisture problems. Ventilation, AC and the choice of materials have in a later stage of the thesis been investigated to enhance the knowledge of moisture protection. The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.
Behaviour and throughput of dairy cows when entering and exiting two types of parallel rotaries
Today a trend can be seen towards fewer dairy farms and increasing number of cows per farm. Larger farms set a higher demand of more labour efficient milking systems. The time to enter and exit milking rotary platforms is crucial to maintain a high cow throughput. This study is a project initiated by DeLaval in order to evaluate the cow throughput and cow behaviour during entry and exit in two types of parallel external rotaries with different bail designs. The two rotaries compared were DeLaval parallel rotary PR2100 and PR3100HD.
Jämställdhet i undervisningen : Några gymnasielärares syn på jämställdhet i läromedel och undervisning
The purpose of this study has been to look into and analyze the view on sex equality in textbooks and teaching media, and teaching of a group of upper secondary school teachers, through a gender perspective. The teachers teach subjects within social- and political science. The two questions that I wanted to answer are: What views do the teachers have on sex equality in their teaching? What views do the teachers have on sex equality in the teaching media (textbooks and other teacher media) which they have access to? Since I wanted to look into the teachers own views I chose unstructured interviews as the method of gather empirical information. To interpret the transcribed texts I chose the hermeneutic view of people as intentional.
