Den här studien gjordes för att undersöka om lärare uppfattar ett samband mellan elevers koncentrationsförmåga och fysisk aktivitet i skolan. Den baseras på en enkätundersökning som gjorts i årskurserna 1-5 på sju olika skolor i närområdet. Studien visar ett positivt samband mellan all fysisk aktivitet i skolan och lärarnas uppfattning av elevernas koncentrationsförmåga, vilket även kopplats samman med tidigare forskning inom närliggande områden. Nyckelord: physical education AND concentration, physcial activity AND concentration ability, physcial acitivty AND effect in school, excercise AND brain, physical education AND brain..

The Swedish Forestry Research Institute implemented an experiment which began in the year 1979 in a by moose browse damaged area in Sweden. An audit in 2014 of the moose browsing study called ?Furudalsförsöket? is the underlay to the study's results. By comparing Scots pine stands development in relation to known damage obtained thereby gives the understanding of how browsing affects the short and long terms impacts of Scots pines quality and volume production. The results of this year's audit reveal that the standing volumes in the undamaged and damaged areas represent a significant difference. The number and volume of the ingrown trees constitute a larger proportion of the areas that have been heavily browsed. It also proves once again that that all damage classes had a downward trend, which means that the damage is concealed with time.

The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types. The data was collected from an electric power line going from the north to the south of Sweden. The mean value of the clearcutted area around the power line was 120 meters. The main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set. The main parameter studied was the damage frequency at the edge of the forest compared to the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated. The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species. A marked difference was observed between tree species and damage frequency.

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Bakgrund: Migration är ett vanligt förekommande fenomen idag vare sig den är ofrivillig eller frivillig. Mycket forskning har gjorts om den ofrivilliga flyktingmigrationen men ytterst lite forskning har fokuserat på den frivilliga migrationen, då i synnerhet gällande högutbildade individer med special kompetens. Avgränsningar: Vi har begränsat oss till att studera de mer rationella orsakerna till inflödet av utländsk kompetens, vilka anses vara lättare för en stat att påverka. Vidare så har vi fokuserat oss mot de individer som anses vara högutbildade eller inneha en speciell eftertraktad kompetens. Studien är också begränsad till att studera migration av högutbildad arbetskraft mellan i-länder.

This study was conducted on a property with a thinning machine team. The purpose was to investigate in which machine, the harvester or the forwarder, that caused most damage to the trees in six different stands. Different factors, related to the damage frequency in the stands, were checked out. For example: basal area per hectare, thinning strength, tree diameter and the rate of production. The harvester drivers were also interviewed about how, when and why stem damages occur and how to minimize them. The study stated that 4.3 percent of the trees were damaged. Out of these 88 percent was caused by the harvester and the rest, 12 percent, by the forwarder..

Obemannade flygplan med attackförmåga (UCAV) används i allt större utsträckning i konflikter idag. En av de främsta fördelarna med dessa är att det inte finns någon risk att mista en pilot, då dessa är fjärstyrda. I attacker utförda av amerikanska UCAV:er i framför allt Afghanistan och Pakistan, har collateral damage inträffat vid ett flertal tillfällen. Det innebär att civila oavsiktligt fallit offer för attacker. Enligt krigets lagar kan sådana händelser rättfärdigas av att militär nödvändighet föreligger, men det är tveksamt om det går att hävda det när man inte riskerar egna förluster.

Background: Studies have shown that 66 children and teenagers in Sweden suffers from brain tumor every year. Children and teenagers who can´t participate in the regular school for a longer time for whatever reason, have by the school law the right to education in hospitals or institutions. Education that take place in other places than school most try to follow the same guidelines as his/hers usual school.  This applies to students in elementary school, compulsory school, special school, Sami school, secondary school and upper secondary school.Purpose:  The purpose of this study was to find out how three teachers at a hospital school plans their work with children in grade from 1 to 3, who suffer from cancer, especially brain tumor.  How can the teachers at the hospital school plan and organize their teaching so that it´s possible for the children whit brain tumor to feel as normal as possible. How does the common work between the consultant nurse, teachers at the hospitals and their ordinary school prevent the children to feel like an outsider?Method: I have chosen to do a qualitative study followed by three interviews whit three informants who works at a hospital school.

Background   The patient's rights to self-determine their own health care is described in Swedish legislation and guidelines. However, due to infancy, unconsciousness, severe Brain damage or certain diseases, some patients might be unable to make such decisions. Ethically difficult situations do occur, not infrequently associated with culture. Since the patient is vulnerable, there is a risk that the patient in the treatment and care can not be bothered to maintain right to autonomy and that the nurse violates patient integrity.Aim                 The aim of this study was to illustrate the nurse's dilemma when the patient refuses vital caring efforts.Method           A literature review of eight scientific articles with a qualitative approach was performed.Results           The results revealed the following domains to describe the nurse's dilemma when the patient refuses vital care interventions: patients? reasons for treatment refusal, the nurse's understanding of the patient's refusal of care and contradictory legislationConclusion     More knowledge and discussion of the patient's decision-making competence is needed for both the nursing profession and those who make decisions on legislation..

In the Kolmården area, northeast of Norrköping in south-central Sweden, it was discovered that shoots of spruce Picea abies, plants to a seemingly large extent had been browsed by deer. The area inhabits a dense red deer population, alongside with moose and roe deer, and red deer is thus suspected to cause the damage. The main purposes of this study are, however, to estimate the extent of the shoot-damage and to investigate what factors that may affect the browsing of shoots. For each stand information was recorded about the age of the plants, area for the stand, height over the sea for the stand, site productivity, type of plants and stand-history. The study was done in three areas: Simonstorp, Stavsjö and Valinge. At Simonstorp and Stavsjö, respectively, 10 stands were chosen for study and on Valinge six stands. In each stand, 10 plots were sampled.
