The aim of this paper is to find an algorithm to establish and maintain a virtual enclosure around a mobile unit. The area may take any form and should be scalable up to and including national borders. The enclosure is managed on the mobile unit. The target system is Android. Smartphones, tablets and more recently, cameras is examples of mobile units.

After recognizing a lack of children?s voices in the debate about the children?s book Kivi och monsterhund and the gender-neutral pronoun hen that occurred in the beginning of the year of 2012, I decided to interview pre-school children about the same book. My purpose with the study was, using semi-structured group interviews, to examine how 6-year olds talked about the main character Kivi. With the help of Judith Butler?s theory of performativity, I have studied how the children constructed Kivi?s gender in their speech.

During the time of membership in The European Union Swedish domestic policy has gone through many changes. A lot more political areas are being influenced by the EU policy. Today every ministry has got some sort of EU office. Swedish politicians are functioning on two arenas, domestic and European. At the same time Swedish membership has gone from being highly discussed to being a state of normality.

Acute bacterial prostatitis is a common disease in older male dogs. It gives symptoms such as fever, pain, tiredness, infertility, unwillingness to mate and sometimes symptoms from the urinary tract. It is common that you do an ultrasound exam on dogs when you suspect prostatic changes. In this study 15 dogs diagnosed with acute prostatitis at the small animal clinic at SLU in Uppsala were examined. The clinical signs and the ultrasound pictures were put together in retrospect.

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.

Semi-natural grasslands are threatened biotopes in the landscape and without conservation measures high values of nature will be lost. Meanwhile, the biological values associated with cultural values of the traditional agricultural landscape in Sweden. Studies of land use history may help to understand how today biological diversity has evolved and how it can be preserved. Färsna farm in Norrtälje has left some of the old heritage of biological diversity in the form of nature - forest and grassland, which hosts an unusual herb-rich flora. Through the study of historic maps and från1673/1767/1801/1901 1952 and orthophoto of the area has a picture of how land use has changed over time emerged.

Contortatall (Pinus contorta ssp. latifolia) började planteras storskaligt i Sverige runt år 1970 men det dröjde till 1987 förrän Sverige lagstiftade begränsningar för hur den fick användas i skogsbruket. Detta gjordes bland annat på grund av att det saknades information om dess spridningsförmåga. Contortans spridningsförmåga i Sverige är fortfarande okänd och lagstiftningen är densamma. För att kunna beräkna spridningsförmågan och i förlängningen den potentiella etableringsframgången behövs kännedom om contortans fröproduktion i Sverige.

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.

Att ha automatiserat grundläggande additionskombinationer i talområdet 0-20 kan underlätta elevers vidare matematikutveckling. I detta utvecklingsarbete undersöktes om ett interventionsprogram bestående av strategidiskussioner, kombinationsträning samt minuttest i årskurs 7 var effektivare än enbart minuttest. Vidare analyserades om ökad säkerhet med additionskombinationerna 0-20 ledde till en generalisering till addition inom talområdet 20-99 samt till subtraktionskombinationer inom talområdet 0-20.En mixed ANOVA med enkla kontraster genomfördes och resultatet visade att interventionsgruppen utvecklades något bättre än jämförelsegruppen under interventionsperioden fram till eftertestet i addition 0-20 men det fanns ingen statistiskt signifikant skillnad mellan grupperna för hela testperioden. Generalisering skedde till addition 20-99 för båda grupperna men interventionsgruppen utvecklades bättre än jämförelsegruppen i subtraktion 0-20. En slutsats är att det är en fördel för eleverna att bli säkrare på de grundläggande additionskombinationerna då de även blir säkrare på addition inom talområdet 20-99 och med träning även säkrare på subtraktion inom talområdet 0-20.

This paper, called Pupils' practice of source criticism on the Internet, is investigating pupils? use of source criticism. The main research question was: how much knowledge pupils from an upper secondary class have about the use of source criticism, regarding examining data from the Internet intended for assignments. Furthermore, developing a suitable method to investigate this was included. The main research question led to further sub questions that aimed to answer to what extent pupils consider source critique criteria as sender, aim, up-to-dateness, credibility and dependence.The study has been conducted by using mixed methods, both qualitative and quantitative methods.

Bakgrund: Hög arbetsbelastning hos omvårdnadspersonal är ett problem både i Sverige och internationellt. En ökad förståelse av hur arbetsbelastning påverkar patientsäkerheten krävs för att förebygga fler vårdskador inom vården. Syfte: att belysa vilka faktorer som skapar arbetsbelastning hos omvårdnadspersonal och dess betydelse för patientsäkerhet. Metod: Litteraturöversikt där studier som undersöker arbetsbelastningens påverkan på patientsäkerhet granskades. 15 studier valdes ut via Pubmed, Psycinfo och Cinahl, där 11 var kvantitativa, två var kvalitativa och två var av mixed design.  Resultat: Faktorer av betydelse för arbetsbelastningen som hade ett samband med patientsäkerheten var ?stressrelaterade situationer?, ?antal patienter i förhållande till personal?, ?antal arbetspass och längd? och ?personals erfarenheter?.

Ten years ago the public computers with Internet access were introduced in the public libraries. The purpose of the public computers was to give the possibility of searching information. Along with the Internet came also communication media like chat and e-mail. This type of communication was a new function for the libraries and the reactions among the librarians were mixed. It has been a source of big frustration and attempts to block it has not succeeded.

A change of generations occurs several times during a company?s lifetime. It is a process that requires planning and time. If the current owner wants to keep the company within the family, he has two options; he can either sell the company to a family member, or give the company to the new owner, like a gift. When the owner sells the company, it is common that he accomplishes it to a losing price.

The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.

Parents today can be very stressed at the drop off and pick up of their children, this leads to that they sometimes miss important information that is pinned to the walls for example. Papers has the ability to disappear, a blog collects all in one place. Today, almost everything is digitized.This study has examined what a blog is and how schools and preschools can use it. The blog is used as a communication site for the preschools and school. This exam graduate work is made of three blog analysis, the analysis is made to see if the blogs can help the preschool and school to communicate wiht the parents.The theory I have decided to use in this study is the sociocultural theory.
