Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges. The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.

Post-anaesthetic myopathy (PAM) is a serious occasional complication of general anaesthesia in horses. It causes not only pain and suffering to the horse, but also suffering (trauma) to the owner with increased veterinary costs. In the worst case PAM can be fatal. The anaesthetic nurse must know which parameters have to be taken into consideration in the prevention of PAM, to be able to prevent it, and use that knowledge for the animals safety. The aim of this literature review was to investigate and make a presentation of the factors and measurements associated with PAM, with focus on how to monitor these measurements to prevent it from happening, and the advice a Veterinary nurse can give to the horse owner regarding this condition. According to literature there a few factors that greatly increase the risk of PAM, these include- hypotension, periods less than 60 mmHg significantly increases the risk.

Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.

Since a few years back television has been on a verge of an enormous digital change. Web-TV is now growing at an incredible rate and is said to completely change the way we consume TV. The purpose of this essay is to determine and gain an understanding of how representatives of the broadcast industry looks at the phenomenon of web-TV and especially the different kinds of online video services and how they believe this will affect the television. Methods used are qualitative interviews which we compared with previous studies on the subject and acknowledged communication theories. The respondents were people with good insight and understanding of the media and TV industry.

The purpose of this essay is to test for significance between TED- spread and four different macrovariables, housing prices, Federal funds rate, Asset Backes Securities and mortgage volume. Multiple regression has been used to search for significance between the dependent and the four independent variables. Our data consist of quarterly reports from January 1998 to June 2008. Our conclusion is that all of the four variables show a significant relation with TED- spread. The model explains 76 percent of the variation in TED- spread..

In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..

This paper describes a factor analysis applied at the data of the European Union structural indicators. These are the official indicators for wealth and economic development in the European Union with main use to evaluate the outcomes of the year 2000 Lisbon goals for making the European Union the world?s strongest economy by 2010. The purpose of the data is to serve for comparing and ?learning by doing?-policies, but have, due to size and format, so far been hard to use for a good compare between member countries.

Syftet med denna studie är att belysa ungdomars tankar kring sina framtida levnadsvillkor.Genom en kvalitativ ansats intervjuades ungdomar kring frågor om vidare studier, arbete, ekonomi och huruvida de ville flytta hemifrån. Urvalsgruppen bestod av 8 ungdomar av båda könen. En avgränsning var att ungdomarna skulle gå årskurs 3 på gymnasiet.Studiens resultat visade att ungdomarna kunde tänka sig att ta det arbete som erbjuds om de inte hade möjlighet att välja. Om de hade ett val, kunde ingen av ungdomarna i studien tänka sig att gå arbetslös och ta emot ekonomiskt bistånd i stället för att arbeta. På sikt tyckte de dock att det var viktigt att ha ett meningsfullt arbete som de trivs med och tycker är kul.Ungdomarna tyckte att det var viktigt att få en bra utbildning då detta är avgörande för hur man klarar sig i framtiden.

Our purpose was to investigate the schools and the social welfare´s experiences of Roman children´s school situation in a Scanian town. We have done a qualitative investigation, interviewing 14 persons from both school and social welfare. Through the interviews we wanted to find the factors which influences the Roman pupils schooling and which efforts the professionals has to their disposition to influence these children´s school situation in a positive direction.The main result of our study is that the majority of the Romans is an isolated group, both in the Swedish school system and in the society. The Romans got access to the Swedish comprehensive school first in 1965, which implies that the Romans have a young school tradition. Most of the Roman pupils have a high absent, which is grounded in a complex of problems.

Den digitala utvecklingen både i samhället i stort och inom utbildning accelererar som aldrig förr. Många ungdomar idag har tillgång till digitala verktyg så som dator, mobiltelefon, surfplatta mm. Detta ställer nya krav på utbildning och därmed också nya krav på lärarna. Ett urval av matematiklärare på gymnasienivå fick i en webb-survey rangordna vilken kunskapsnivå de anser sig ha med avseende tre huvudområdena som beskrivs av ramverket Technological Pedagogical Content Knowledge (TPACK): teknik, pedagogik, ämnesinnehåll och kombinationer av dessa. Resultaten visar att lärarna anser sig ha en hög kunskapsnivå med avseende på pedagogik och ämnesinnehåll samt kombinationen av dessa men att kunskapsnivån ligger lägre när det gäller teknik och då framförallt den rent tekniska biten (t.ex.

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

Municipal Real Estate Companies runs by a political boarder who makes decisions in large investments. In some cases the municipal counter have to take the decisions about big and expensive investments. A successful investment needs to be built on solid ground.Media has lately focused on energy topics as a part of the environmental discussion and the real estate companies tries to use the new technology that the market has provided. Energy investments in new buildings are not longer a small part of the energy saving program. Long-term investment demands needs large knowledge and awareness about the energy topics that have recently grown in the municipal real estate companies.

I takt med den ökade internationaliseringen så ökar osäkerheten för företagen vad gäller valutakurser, räntor, inflation, efterfrågan och konkurs. I dagsläget utsätts i stort sätt alla företag för någon form av valutaexponeringen, antingen direkt eller indirekt. Olika företag skyddar sig på olika sätt beroende på storleken på företaget. Vare sig om det är ett stort eller litet företag är det är extremt viktigt att skydda sig mot valutarisker som uppkommer då man gör affärer utomlands. Syftet med denna uppsats är att utreda om det är någon skillnad på hur stora och små företag hanterar och skyddar sig mot valutarisker, vilka metoder som är vanligast och varför man väljer det ena före det andra.

Abstract  Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.
