Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.

The purpose of this Master?s thesis is to examine how the gender system is described in chick lit. The analysis is based upon seven chick lit novels. The primary theoretical point of departure is Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes.

Lantmäteriet använder idag ett verktyg för fastighetsvärdering, detta verktyg består av ett system med spridd arkitektur för att lagra fastighetsdata och geografisk information. Studien syftar till att undersöka vad det finns för alternativa tekniker och lösningar för att integrera spatialdata och fastighetsdata i samma databas. För att finna svar på detta analyseras litteratur, svar från enkäter som besvarats av slutanvändare samt resultat från djupintervjuer av systemexpter. Resultatet visar att tekniker som t.ex. ArcSDE och Oracle Spatial kan lösa det angivna problemet.

This paper appeals to professionals working with green questions. It intends to create a discussion about which plant species that can be established in a fieldlayer of a naturelike planting on fertile agricultural land. To initiate the essay, a studie of which values that can be connected with an establishment of a fieldlayer was performed . A part of Tor Nitzelius Park in Alnarp, a so called naturlike planting on fertile agricultural land, was used as a model for the choice of species. With the aid of soil values, photos and a list of current species, interviews with four ecologists were performed.

Vid utveckling av nya system finns det flera olika modeller/metoder att använda sig av, till exempel prototyping eller vattenfallsmodellen. Denna uppsats beskriver hur utvecklingen avett webbaserat system för registrering av datorer kan ske med hjälp av vattenfallsmetoden. Fokus på detta arbete ligger förutom själva utvecklandet av registret också på dokumenteringen av de olika stegen som följts enligt vattenfallsmodellen. Detta arbeteförsöker också svara på om denna modell är lämplig att använda vid utvecklingen av liknande system. Uppsatsen tar också upp fördelar och nackdelar om kan uppkomma vid användandet av denna modell..

The work is performed at Forsmark Group AB as a final step in the Bachelor ofScience program in nuclear engineering at the University of Uppsala in 2013.The work is part of an ongoing process of streamlining project system model FKA.Streamlining the project model is an important aspect that affects all largecompanies that somehow have a project governing body when there is muchfinancial resources to save. Although the quality of the projects is positivelyaffected by efficiencyThe aim is to find possible common weaknesses and strengths of the project systemby interviewing a number of project managers, and using the systems in placeexamine the model.As part of the work also includes examining what project managers have to adjust tothe newly implemented system VPMM, and other newly introduced elements thathave been added to improve the efficiency in the futureProject System is a complex system that is influenced by many different parametersand participating individuals' attitude and personality. But then small changes in themodel could have major economic consequences.The thesis has generated results that show common weaknesses among the variousprojects and their project managers' general opinions about the project model. It alsopresents some possible solutions based on own thoughts and those interviewedobjects suggestions and comments..

The aim of this study is to look into the correctional system?s work with parent ship of incarcerated mothers and fathers from a gender perspective. It is a qualitative study and two interviews have been done with employees from a prison for women and one interview from a prison for men. Two interviews have been done with two former incarcerated parents, one mother and one father. One interview has also been done with an organization which gives children with incarcerated parents support and an opportunity to meet other children in the same situation.

This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing people from outside the company in a simulated Xbox Live Indie Games test environment; excluding this developed system there is no other way to do such an analysis without actually releasing the game on the Xbox Live Indie Games marketplace and then analyze the resulting sales from the product.The finished system had to be similar to the original system to the degree that a user could see past the interface itself and use the system just as he/she would have used the real marketplace. It also had to be easy to change and add games to the system so that Ludosity Interactive easily could show the games and the data that they deemed interesting for their tests. The final product was developed using C#, XNA and XML together with an Agileinspired development method in combination with Pivotal Tracker. This report describes how this product was developed..

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

AimThe compulsory school attendance in Sweden means that all children are obligated to go to school. This makes great demands on those who work in the school, especially the teachers. Schools are complex units. In school, teachers face all kinds of ethical dilemmas on a daily basis. The aim of the study is to enlighten how different teachers would act differently, if they were facing the same dilemma in the PE-lessons and why this knowledge is important to our profession.MethodThe data was collected through interviews to make a qualitative research.

The number of public schools in Sweden has increased strongly over the past twenty years. This essay gives a possible explanation to how the Social Democratic Party in Sweden took part in this evaluation from 1987 to 1997. I've analysed how the party's ideology in this issue was shaped and adapted to the opposite politics, when the Liberals and Conservatives Parties were in government.The empirical analyse is primarily based on official documents from the Parlament such as debates, government bills and motions. I have also studied the Social Democratic Party's congresses which took place during this period of time. I have practised two different theories in analysing the motives behind the acting.

När organisationer implementerar ett nytt ERP-systemligger deras intresse påkonkurrensfördelar och ekonomiska vinster. Det fokuseras på vilka fördelar systemet kan georganisationeni form av snabbare ledtider, reducerade kostnader, bättre beslutsstöd och resursöversikt. Dessa konkreta fördelar ärävenlättare att hålla koll på och att mäta. Svårigheter finns i att hantera fördelar som systemet kan ge användarna. Implementation av ett nytt, verksamhetsövergripande, ERP-system kan påverka kärnprocesser, arbetsmönster och uppgifter.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.
