Plant defensive mechanisms against insect pests

This study has focused on testing the following two hypotheses:? Pest resistant plants have higher levels and/or several different kinds of secondary metabolites. ? Induced defensive systems in resistant plants are activated more rapidly than those of susceptible plants. As a background for the test of the hypotheses a short literature study was performed concerning plant defensive mechanisms in Arabidopsis thaliana.

Barns läsning av facktexter. En studie av skolbibliotekariers och pedagogers syn på barns läsning och förståelse av facktexter.

The aim of this Masters thesis is to analyse school librarians and teachers perspective of childrens reading and reading progress, the impact of informational texts on childrens reading and how school librarians and teachers work/teach to improve their students understanding of informational texts. We also intend to study what consequences school librarians and teachers believe that childrens reduced understanding of informational texts can have in the long run and how this could be improved. The theories applied encompass different literature-pedagogical strategies, theories about reading purpose and direction of the reading process together with a theory that shows the school librarys function in the education. The empirical material has been collected through interviews with one school librarian and one teacher at three different schools. The material has then been analysed and interpreted from theories and earlier research.

Police Science - expansionen av ett kunskapsfält : En studie om vetenskapligt gränsdragningsarbete i 1930-talets Chicago

In 1929, the Scientific Crime Detection Laboratory was established in Chicago?the first of its kind in the United States. The purpose was to engage in practical use of scientific methods in the detection of crime. In 1930, the institute published its own periodical called The American Journal of Police Science. Applying the theory of boundary-work, this essay analyses how the novelty institute argued its legitimacy as a scientific establishment through the expansion of Police Science as a collective field of knowledge.

Laserinkopplingselement För XFEL Laser Heater : Från Idé Till Färdig Produkt I Designstadie

Uppsala University is involved in a large international collaborationto build the Laser heater system for the European Xray Free-electronlaser in Hamburg, Germany. In this thesis I describe a laser incouplingdevice into the vacuum chamber of this laser heater all the way fromthe specifications to a completed design.The laser heater is a very important part of the XFEL and thepart described here is a part of the vacuum system needed to couplean external laser into the electron vacuum system and align it withthe electron bunches in order to heat them. The task was started by studying the literature about the basic theory andthe design of vacuum systems. After this study and collection of ideaswith colleagues I started to prepare different concepts to solve thetask. The ideas can be put into two categories, in one case the couplingmirror is located inside the vacuum chamber and in the second caseoutside.

Lärsituationens komplexitet för elever som upplever svårigheter i matematik : Rutiga Familjen i en ny lärmiljö

The Squares Family is a game developed as a learning aid in mathematics. With its graphical representation of the decimal system, the four basic arithmetic operations and positive and negative numbers together with a learning agent as pedagogical approach, the game?s primary purpose is to motivate students in their learning of mathematics. Although the game is strictly based on mathematical rules it attempts to encourage students to play and work with math without experiencing it as mathematics as this is initially not obvious. The game being internationally tested on normal performing students, this project introduced the game to six Swedish students who experience low motivation for and/or difficulties in mathematics.

Att äta kakan och ha den kvar : En hållbarhetsprövning av John Haughts evolutionsteologi

From underwater boat to submarine ? The development of the Swedish submarine service 1945-1960 The scope of this essay is the development of the Swedish submarine service during the period 1945-1960. The aim is to answer the following questions:- What kind of new technology did Sweden acquire when salvaging the German type XXI submarine off Gothenburg at the end of World War II?- In what respect did this technology differ from that of the Royal Swedish Navy and did it subsequently contribute to the tactical and operational development?- What tactical and operational development was accomplished between 1945-1960?The timeframe, 1945-1960, was chosen since this is when the analysis of the salvaged type XXI submarine and related effects was conducted. Furthermore, it is also during this time that the Swedish submarine service is beginning to evolve as a result of the new knowledge mentioned above and the experiences made by both the allies and the Germans during World War II.The theoretical framework primarily refers to the theories on naval warfare by Sir Julian Corbett.

Revisionsbyråernas syn på jävsregeln i Aktiebolagslagen

AbstractTitle: Accounting firms´ view on the (new law) in joint-stock companiesCourse: Business Administration, Financial Accounting in Corporations and Groups, Ad-vanced Course, 15 ECTSAuthors: Mikaela Uveby, Shadi Nourbehesht, Almira DizdarevicAdvisor: Kent TrosanderProblem: During the last few years, more importance and emphasis has been put on auditors and accounting in general due to a number of company and business scandals on both national and international levels. The United States as well as the EU consid-ered it a necessity to make regulations stricter when it comes to auditing and ac-counts in order to increase the public trust to accounting. At January 1st, 2007, Sweden also changed its law concerning accounting firm challenges. The new law states that as soon as someone of the auditor?s co-workers assists a client with some part of the basic bookkeeping, the main bookkeeping or the drawing-up of the an-nual account, the challenge situation becomes a fact.Purpose: The purpose of the essay is to examine and inquire into how the renewed law con-cerning accounting firm challenges, that was established and put to action at Janu-ary 1st, 2007, has affected accounting firms.Method: The writers have chosen to complete qualitative interviews in order to get a deeper insight to and an understanding of the topic.Conclusion: One year after the renewal of the law, the writers have reached the conclusion of that the new law has not had a great impact on the accounting firms.

Framtagning av lämplig teknologi för konvertering av VBA-applikation till Internet Explorer

Företaget GUTAB använder idag en frågeanalysmodul som är utvecklat i Visual Basic for Applications i Microsoft Excel. GUTAB fann det intressant att veta om modulen kunde konverteras till webbläsaren Internet Explorer samt vilken teknologi som var lämplig för detta. GUTAB var även intresserade av att veta vilken teknologi som kunde användas för att skapa grafiska manipulerbara objekt.En skrivbordsundersökning genomfördes som omfattade teknologierna ASP, ASP.NET, JSP, PHP, ActiveX samt Java applets. Skrivbordsundersökningen utgjordes av två delar där den första delen redogjorde för de två klientbaserade teknologierna ActiveX och Java applets med vilka grafiska manipulerbara objekt kunde realiseras. GUTAB ansåg att ActiveX program var mest lämpliga för detta ändamål.Baserat på skrivbordsundersökningens andra del bestämde GUTAB att ASP och ASP.NET skulle användas för att testa teknologiernas kapacitet att konvertera programlogik samt grafiska objekt från VBA-applikationen i en webbapplikation då dessa två teknologier ansågs som mest lämpliga för en konvertering.Testet som genomfördes visade att det var fullt möjligt att konvertera utvald funktionalitet med båda teknologierna.

Konstruktion av infästning till dysa

The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.

Användning av geografiskt informationssystem (GIS) vid studier av nötkreatur i landskapet - en pilotstudie :

The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.

"Annan finansiell verksamhet" - En tolkning i ljuset av CFC-lagstiftningen : En tolkning i ljuset av CFC-lagstiftningen

The initial provisions concerning CFC-legislation were introduced 1990 and has since been subject to several revisions and adaptations. The fundamental purpose of the CFC-legislation is to prohibit and prevent tax evasion undertaken by such companies that own other foreign companies where generated income is subject to low rates of taxation. The CFC-legislation aims to provide the Swedish government with an op-portunity to tax this income. This is important in order to prevent tax avoidance and preserve the integrity of the system of taxation within Sweden. In order for the CFC-legislation to be as effective as possible there must exist a clear way of defining which activity that is to be regulated within its scope.
