Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

The purpose of this study is to investigate how male and female is produced in the literary children?s literature that is found in a Municipal preschool. My issues are the following:Which sex dominates as a main character in the preschools literary books?What type of properties is attributed to the characters?What type of clothes is portrayed on the books characters?I performed a quantitative study of 136 children?s books. I used Maria Nikolajevas perceptions of stereotypical male and female properties to analyze my empirical data.

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

Att genomgå en amputation kan upplevas som en stor livsomställning där patienten behöver acceptera förlusten av kroppsdelen för att kunna gå vidare med sitt liv och uppleva en god livskvalitet, trots en kvarvarande grundsjukdom. Patienten genomgår en transition och lär sig hantera sin nya situation och finner mening och begriplighet. Genom en känsla av sammanhang kan patienten få en ökad livskvalitet. Syftet med denna litteraturöversikt var att belysa faktorer som påverkar patientens livskvalitet efter en amputation av nedre extremitet på grund av diabetes eller kärlsjukdom. Artiklarna söktes i databaserna PubMed och Cinahl, där inklusionskriterierna var amputation av nedre extremiteter som genomförts på grund av diabetes eller kärlsjukdom.

Bakgrund: Hälso- och sjukvårdslagen fick år 2010 en ny paragraf som resulterat i nya riktlinjer i flera av Sveriges landsting angående bemötandet av barn som anhöriga. Årligen förlorar 3361 barn en förälder på grund av svår sjukdom och detta kan resultera i en sämre fysisk och psykisk hälsa hos barnet. En ökad medvetenhet inom sjukvården skulle möjliggöra igenkännande och stöd till drabbade barn. Syfte: Att beskriva hur barn hanterar sin situation då en förälder är svårt sjuk och hur sjuksköterskan kan stödja barnet. Metod: En litteraturöversikt baserad på 13 studier med kvalitativ ansats.

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.

Decision-making and valuation when buying small caps is a poorly explored area. Likewise, since disputes about deficiencies in the company?s financial and legal standing are, almost without exception, resolved in arbitration with confidentiality requirements for both sides, there is very little empirical knowledge about such disputes. This paper hopes to add empiric experience by describing such a take-over ? the purchase of the Jon Blund companies.

Denna uppsats handlade om att genom en textanalys studera hur två hälsotidskrifter, Hälsa och Må Bra, framställde ämnet kost och hälsa. Hälsoupplysningen började under 1700-talet, med skrifter och utvecklades därefter till ett allt större forum i takt med samhällsutvecklingen. I dagsläget kunde jag identifiera flertalet sätt där hälsoupplysning förekom som tex. via TV, internet, massmedia, reklamannonser, apotek, hälsokostaffärer, dagstidningar, tidskrifter, etc. Av detta urval valde jag att genom en textanalys, samt genom att hämta inspiration av några analysredskap, som metaforer, intertextualitet samt modalitet, studera hur tidskrifterna genom sina artiklar valde att framställa kost och hälsa.

The aim of this study was to examine differences between happy and unhappy people, with respect to individuals interpretations, their attributonal style and in what way the priming effect is related to their attributional style and well-being. The participants were 74 senior high school and 21 undergraduate college students. Participants were asked to read a short story, some words were in bold type, and thereafter for their subjective perception of the words in bold type loading and memory of them in a recognition list. Attributional style was operationalized with an own constructed instrument. The results show that happy individuals interpreted more words as positive than negative in comparission with unhappy individuals.

The purpose of this study was to understand how social workers experienced working with Addiction Severity Index (ASI) in relation to the goal set by the National Board of Health and Welfare. The method is spread nationwide and therefore it is of great importance to examine how the social workers themselves experience the demands and the resources surrounding ASI. We choose to do a qualitative study interviewing eight social workers at six different occasions. The result was analyzed using Max Weber?s ideal type bureaucracy and Michael Lipsky?s thesis on street-level bureaucrats.

Background:Companies of today commonly search to gain competitive advantages throughout different forms of co-operation, one of which is referred to as Supply Chain Management. Although little research has been assigned to the topic of how to manage and control this type of relation, lately a growing number of academics has been arguing that ABC is an appropriate mean of controlling this type of relationships.Purpose:The purpose of this thesis is to investigate to what degree the ongoing debate on the use of ABC as a mean of control within SCM correspond to the present theories related to ABC and SCM respectively.Research method:The thesis takes it?s starting point within the literature, meaning that the empirical information consists of published articles in the ongoing debate. This information is put in relation to the original theories concerning both topics.Conclusions:The results shown in the thesis in some content agrees with the ongoing debate referring to the positive aspects that could result from using ABC as a mean of control within SCM. However the main result of the study is the discovery of a lack of discussion concerning the problems that implementing ABC within SCM might implicate, a fact that we believe contributes to the mainly positive view on using ABC within Supply Chain Management..

As today, companies are facing an increasing competition; markets are expanding while customers are getting more informed and fastidious toward companies and their products. For this reason it is crucial for enterprises to create loyal customers, or at best hyper loyal customers. With today's prerequisite this creation is difficult and it is therefore of highly interest to examine possible and alternative ways for enterprises to attain this type of hyper loyal customer. In this thesis we have examine hyper loyal football supporters with the aim to identify mechanisms that create and characterize this type of loyalty. By means of a survey and a focus group we were able to identify six loyalty mechanisms; the ability to influence, vicarious achievement, self-esteem, group affiliation, family and social relations.

Bakgrund: En ökad medveten närvaro kring måltiden och ätandet genom mindful eating har i ny forskning visat sig vara en effektiv metod för att minska en rad olika sjukdomar och hälsorelaterade problem samt bidra till gynnsamma hälsoeffekter. Trots detta finns få studier genomförda i en svensk kontext.Syfte: Undersöka och beskriva graden av mindful eating hos en grupp individer på sociala medier i förhållande till Body Mass Index och demografiska variabler.Metod: Deskriptiv tvärsnittsstudie med en kvantitativ ansats. Ett tidigare utvecklat instrument, Mindful Eating Questionnaire (MEQ), översattes och distribuerades som en webbaserad enkätundersökning. Respondenterna rekryterades under en veckas tid genom ett snöbollsurval på det sociala nätverket Facebook. Inklusionskriterierna var att deltagarna skulle behärska det svenska språket, vara mellan 20-65 år och användare av Facebook.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

Jönköping Small Animal Hospital is today the only clinic in Sweden to offer radiation therapy as a treatment of tumours. The body contains of billions of cells that all have to obey the regulations that are established. If a cell is exposed to a harmful substance, for example a chemical, it can be transformed into a tumourcell. Normally the body has a good defence but the tumourcell can survive and start to divide unrestrained. A tumour is starting to develop.
