Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

Marknadens reaktion när ett företag informerar och annonserar om en eventuell nyemission sägs vara oförutsägbar. Enligt tidigare forskning pressas aktiekursen i de flesta fallen nedåt vid en nyemission. Under det senaste året har en del nyemissioner utförts i synnerhet på grund av den globala lågkonjunkturen då många företag haft för lite kapitalbas. Vad gäller företag på Stockholmsbörsen som valt att nyemittera aktier har även här de flesta fått se sin aktiekurs rasa.Författarna till denna uppsats avser att studera hur marknaden reagerar på ett offentligt tillkännagivande av en kommande nyemission. Det undersöks även om det förefaller någon skillnad mellan tillkännagivanden av nyemissioner genomförda innan eller under lågkonjunkturen och skillnader branscher emellan.Då vi ville se hur denna händelse påverkar ett företags aktiekurser valde vi att göra en eventstudie.

Börsnoterade bolag i spelbranschen med pokerklienter har det senaste året haft kraftigt stigande aktiekurser. Vår uppsats ämnar undersöka om dessa företag är övervärderade på grund av det stora ökade intresset för poker. Vi har genomfört analyser med hjälp av target price och multipelvärdering. Vi har förklarat hur regressioner på dessa bolagen ser ut samt koncentrerat oss ytterligare på vad som driver Unibets aktiekurs. Det resultat vi har kommit fram till är att branschen i sin helhet inte är övervärderad utan snarare korrekt prissatt, med reservation för eventuell undervärdering.

There are various value-influencing factors that have various effects on the value of a cooperative flat for buyers. What generates value is individual and different from buyer to buyer, but also between buyers and real-estate agents. Consequently, the real-estate agents who perform valuations can make incorrect estimates of a residential value. Therefore, it is important to examine which factors are important for buyers to prevent incorrect valuations. To find out which these factors are and which of them that are the most important for potential buyers, previous research has been done in larger cities in both Sweden and other countries.

Introduktion: Det finns många olika ytbehandlingar för glasögon tillgängliga i butikerna. En av dessa är antireflexbehandlingen som har till avsikt att eliminera reflexer som annars uppstår i obehandlade glas.Syfte: Detta är en studie vars syfte var att undersöka om antireflexbehandlade glasögon kan ge upphov till bättre syn jämfört med vanliga obehandlade glas.Metod: Nitton försökspersoner blev tillpassade två par glasögon var. Glasögonen var identiska förutom att det ena paret var försett med antireflexbehandling på glasens främre och bakre yta. Synskärpan testades med en LogMAR-tavla. Kontrastskänsligheten provades dels med Vistech chart på 3 meters avstånd och dels med Mars Contrast Sensitivity Test på 50 centimeters avstånd.Resultat: Testresultaten visade på en statistisk signifikant bättre synskärpa med de antireflexbehandlade glasögonen i normal rumsbelysning.

The purpose of this study is to evaluate the real aggregated consumption and empirically determine its exogenous variables. A multiplicative analysis is done in the context of government stabilization policy to find out how policymakers can execute a stimulus package that will bring the best multiplicative effect to the economy The conclusion of the study is that real income, net financial assets and real-estate price index are all statistically significant. An effective expansive fiscal policy is a public-financed investment in the private sector. Coordination is going to be crucial when stimulus package is developed due to the fact that leakage in the form of imports will prevent the expected multiplicative effect..

Sound surrounds us in a great extent, we all have experiences of sound and this phenomena has a great meaning in our lives. High levels of sound might be harmful for your hearing and might also cause related difficulties such as tinnitus and sensitivity to sound. Studies reveal a connection between the attitudes toward high levels of sound and the risk behaviours in these situations. The purpose of this study was to explore the experiences and meaning of sound and whether the attitudes toward sound will reflect in a family consisting parents and adolescents. A family consisting two parents and two adolescents participated each and one of them in an interview in this qualitative study that has been carried out of a phenomenological approach.

?Det finns en chans att man hittar ett unikt plagg som ingen annan har.?(Kommentar från undersökningen)Idag används second hand kläder flitigt av trendsättare och kändisar och är ofta ett återkommande tema i modetidningar och styling jobb. Kända personer som skådespelerskan Josephine Bornebusch och artisten Agnes Carlsson förespråkar second hand och har alla second hand- kläder i sina garderober. Två detaljhandelsföretag som är välkända inom second hand- branschen är företagen Myrorna och Beyond Retro. Trots att de är verksamma inom samma bransch, andrahandskläder, har de enligt oss fokuserat på olika element som gör dem konkurrenskraftiga.

This thesis examines some special education teachers with experiences of childrendiagnosed with dyscalculia. Problems with mathematics at school may occur to allchildren in all schools. It is therefore important that the teacher knows the variousdisabilities that teachers may encounter. The study is based on four randomlyselected special education teachers, all-working at schools that are related to amedium-sized Swedish town. This work will immerse in the knowledge ofdyscalculia among four special education teachers.The interviews revealed that all special education teachers felt that dyscalculiainvolves specific difficulties in mathematics, their views on dyscalculia is consistentwith current research.

From a historical perspective, Sweden is a classic example of a social democratic state in view ofits early development of labor movements, democracy and focus on the welfare state. Today, as amember state of the EU, Sweden has however come to be influenced by America?s neoliberalpolities, where companies need to deliver more and better products/services while the consumerawareness and sensitivity has increased about company?s way to invest. Research shows thatScandinavian companies, primarily in Denmark and Sweden, has a leading position when it comesto responsible corporate behavior which has been the reason to our choice of studying howSwedish companies do to achieve success in CSR. To carry out this study, we have usedqualitative analysis, using semi-structures to interview companies in different industry sectors.

AbstractThe aim for this study is to establish how teachers and supervisors at the Child and Recreation Programme interpret the concept ?vocational knowledge?. It is also about how they substantially can see that the pupils are developing vocational knowledge, during their work placement training. The aim of this thesis is to create a base for teachers to work with continuing development in teaching practice. The empirical part of this study is based on interviews. Interviews were analyzed in three categories: definition of vocational knowledge, substantially developing in vocational knowledge and success factors. The result shows that knowing how and knowing why is salient in vocational knowledge.

The Internet has developed into a marketplace for national and international companies. With relatively small means, a company can reach out to millions of people on a daily basis by placing itself on the Internet. With this report, we wish to suggest how e-businesses can change its strategy to adapt to the new market. Focus is on the Swedish Internet market where Swedes, resident in Sweden, trades with Swedish e-companies active within the Swedish borders. To be able to make suggestions, we will first paint a picture of the Swedish e-commerce market from statistics collected from public sources.
