Biokemisk och immunologisk karaktärisering av pepsin-spjälkade mjölkallergener

Milk allergens were digested by allowing them to flow through a chromatography column, where pepsin was conjugated to the stationary phase of the column. The allergen fragments were then characterized both biochemically, by using SDS-PAGE and gel permeation chromatography, and immunologically, by examining their reactivity to IgE and monoclonal antibodies..

Testdriven utveckling för mobila applikationer/Android

Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.

Individuell utprovning av inkontinenshjälpmedel i kommunala särskilda boenden

The purpose of this study was to examine the extent to which incontinence aids, used in local authority/municipal nursing homes, were adapted to the resident?s urine-leakage volume and to find out how nurses perceived the current situation concerning individual testing of incontinence aids in municipal nursing homes. The study method was a quantitative empirical study and was carried out in two phases. The first phase was a weighing test, carried out in three nursing homes, whereby the incontinence aids used by 25 residents during a 48 hour period were weighed. The second phase was the completion of a questionnaire by the municipal nurses working in the same local authority.

Bäst i klassen? : - En studie av hållbarhetsredovisningar i statligt ägda bolag

Due to the globalization and the changes in the market, companies have now realized the importance of a strong brand. This has led to the phenomena outsourcing. The relation between the branding consultant and his or her client has changed. Earlier the consultants worked as a single unit and were given a task to independently accomplish the assignment. Today there has to be co-operation between the two parties.

Läsplatta som hjälpmedel för dyslektiker

Denna uppsats tar upp frågan om en teknisk artefakt, i detta fall läs- och/eller surfplatta, kan ses som en bra lösning för dyslektiker i deras svårigheter med läsningen. Studien har fokus på läs- och surfplattans funktioner som kan vara en möjlighet att hjälpa personer med läsning. Uppsatsens experiment beprövar en redan etablerad metod, läsa och lyssna samtidigt, genom att sätta samman ett antal funktioner och tekniker som finns idag i en enhet. Vi har undersökt om man kan öka läshastigheten och läsförståelsen hos dyslektiker med hjälp av sådan teknik på en läs/surfplatta. Resultatet visar en trend på att metoden fungerar.

The Zeitgeist Movement : ?Allt kanske inte är som mamma och pappa sa?? EN SOCIALPSYKOLOGISK STUDIE MED FOKUS PÅ ETT ANTAL DELTAGARE I THE ZEITGEIST MOVEMENT

This study´s focus was a group of participants of a social movement called The Zeitgeist Movement. The purpose of this study was to understand and convey what causes participants of this movement to engage despite that the prevailing culture teaches them otherwise.With qualitative methodology of participatory observation and semi-structured interviews with ten participants, our objective has been to answer the following questions: What are the driving forces that make these people act, which approach do they have to ?reality? and how do they relate to it, and what are the potential consequences with this approach?The study has shown that their critical and questioning attitude towards their perception of reality and their social constructivist view of it lead to conflicts between them and their fellowmen. The data was then analyzed with Alfred Schütz phenomenological theories in synthesis with Zygmunt Baumans critical societal analysis and theories.The study's focus was on the Gothenburg chapter of the Swedish Zeitgeist Movement. We did not make any comparisons with other national or international chapters of the movement..

Konflikthantering i klassrummet

We have chosen to focus our study on conflicts and handling of conflicts in a classroom environment. We are addressing problems such as the teachers? roll in a conflict, the importance of solid leadership in the classroom, students? agency, defense mechanisms in coping with conflicts and so on. In this paper there is a review of different perspectives on conflict and of understanding why conflicts occur the different reasons for the conflicts. Our observation study took place in a grade three classroom, in a mid-sized town, during a regular school day.

Hantering av verksamhetskrav : Utredning av hur hantering av verksamhetskrav från kunder kan förbättras på Saab Aerosystems

Saab Aerosystems have had one dominating product, JAS 39 Gripen, and one dominating customer, FMV, for a long time. The operations management system at Aerosystems is adjusted for development of Gripen and as the business unit is trying to enter new markets with other products and customer the operations needs to be adjusted to fit the development and manufacturing of these products as well.The purpose of the master thesis has been to investigate how Aerosystems is managing requirements on operations from external customers and how to make improvements within this area. The aim has been to carry out a situation analysis to identify where improvements are possible and then produce proposals for improvements through studies of literature and other business units. The thesis also include a study of knowledge transfer within the business unit to investigate how this can be applied to improve the managing of requirement on the operations.An extensive interview study has been carried out in which interviews mainly have been conducted with employees at Aerosystems, but also at Saab Avitronics and Saab Aerostructures. The reason why these business units have been examined is because they have carried out a large number of successful businesses with external customers, which also are potential customers for Aerosystems in the future.The interviews have been analysed to identify strengths, weaknesses, opportunities and threats with the present way of working.

Deltack, Blanket Study

There are two objectives of this study.The first one was to study the new instrument Deltack fromPrufbau, and with the new knowledge, study the interaction between blanket and paper.Deltack is a new instrument to measure the ink splitting force. Blankets from an earlier study doneby GATF have been montered on 12 different Deltack print forms and those have together with Deltackbeen the base for this project.This study together with information from GATF?s study shows that some of the blankets have ahigher capability to adsorb ink. Those blankets generate a sharper shape on the force curve, they havea lower dot gain, but they print not as good solid..

?Thy sanningen bliwfer ändånäst Gudz hielp alltid ochallena bestående.? : Naturrättsliga influenser i några karolinskakrigares källor kring 1700.

This study aims to describe the influence of natural law on the common concept of justiceamongst Swedish officers around 1700. Through this study I intend to establish that therewere discrepancies and expressions of other norms in 17th and 18th century military culture.Both from natural law but also from Christian belief. A secondary aim is to establish howsuch variances were manifested and how they can be explained.A few theoretical starting-points have been used as a guide in developing the purpose andrelevant questions for this study. I intend to describe the key features of the concept of naturallaw as thoroughly as needed, through relevant legal literature. The next step will be to mapthese outlines against texts from the time, through a qualitative close reading.This study has investigated, at least, seven diaries from the time.

Utveckling av snabbfäste och verktyg för byte av sågklinga

This thesis is based upon the work done at Westinghouse electric company (WEC)inVästerås during the spring semester of 2015 and describes the development of a quickcoupler with associated blade changing tool. These are meant to be used togetherwith a sawing tool that the company uses for the dismantling of nuclear reactors,which is performed under water.The aim of the thesis was to develop a complete manufacturing documentation withdrawings and related CAD models which Westinghouse later can use to manufacturethe tool and the quick coupler. It was also included in the assignment to, if necessary,modify parts of the saw tool to adapt these to the intended blade changing tool.A number of visits to the company's workshop was made during the time to study thesaw that the thesis is based upon. The purpose of these visits was to get a better ideaof the dimensions, construction and the field of use of the saw. On three of thoseoccasions various engineers and consultants accompanied us to discuss possibleproblems with different ideas.This was interspersed with information in the form of literature studies on quickcouplers to create a clearer picture of the nature of the task.When enough information had been gathered a functional analysis was made to dividethe main problem into subthis phase the idea and concept generating process took place.The methods used for this was mainly brain writing and brainstorming.

Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0

After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.

Vad är ?rätt? gjutkvalitet? Hur uppnås det?

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
