Sover du gott, lille vän? : En studie om mellanstadie- och gymnasieelevers sömnvanor och upplevda prestationsförmåga i skolan
This study has emerged from a growing interest in students' sleeping habits. During practical training as teachers, we have noticed a discussion of students' sleeping habits, fatigue and student performance at school in relation to their sleeping habits. The purpose of this field survey was to examine students? sleeping habits and self-perceived performance ability in school in relation to sleeping habits. The material was collected from a questionnaire that was answered by 200 students in 4-6th grade and 188 students in 1-2th grade in the upper secondary school, this to give an opportunity to see if there were any differences between the different age groups.
Från apparat till App : Public service i ett förändrat medielandskap
This Bachelor thesis is a qualitative study of the public debate regarding the role of Public service in the media converged society today. The purpose of this thesis is to examine how the public debate, that is the Swedish Public service television and people with broad representative knowledge about Public service, motivates a change of the function of the Swedish Public service television.Our issues are: What does the public debate say about the function of Swedish Public service television in our society today and how is a change motivated in this debate? How does the public debate look upon today´s media convergence and the fragmentation of the audience which, according to Denis McQuail, is a consequence of this?The method of this thesis is a qualitative analysis and we have analyzed ten opinion articles and Swedish Public service television magazine ?DittSvt?. The theoretical background was obtained from Henry Jenkins and Håkan Hvitfelts theories and thoughts about mediaconvergence. We have supplemented this with Denis McQuails theory regarding the fragmentation of the audience.In this thesis, we see that the public debate is a lot about diversity in Swedish Public service television programming and that the democratic base is still very important.
Sömnkvalitet hos patienter på rehabiliteringsklinik : Sömnrutiners påverkan på sömnkvalitet
SAMMANFATTNING Bakgrund: Sömn är grundläggande för att människor ska uppleva hälsa och välbefinnande.Syftet: Att undersöka sömnrutiners och omgivande faktorers betydelse för god sömn hos patienter på rehabiliteringsklinik. Metod: En kvantitativ deskriptiv tvärsnittsstudie genomfördes med hjälp av en enkätundersökning på två rehabiliteringskliniker i Stockholm. Patienterna (n=33) togs ut enligt konsekutiv ordning utifrån att de bedömdes kunna fylla i enkäten (adekvata, orienterade till tid och rum, förstod svenska språket). Enkäten, ett validerat och reliabelt redan befintligt frågeformulär, Karolinska Sleep Questionaire (KSQ) användes efter omarbetning. Resultat: Den sammanlagda bedömningen av sömnen utifrån de fyra indexen, sömnkvalitetsindex, uppvaknandebesvärsindex, snarkbesvärsindex och sömnighets/trötthetsindex visade att det var 76 % som ansåg sig ha dålig sömn.
Skolmiljön som potentiellt kompensatoriskt mikrosystem för barn som upplevt våld mot mamma
This paper aims to examine how children who have experienced violence against their mother experience their school and if the school somehow can compensate for the vulnerable situation of the children?s home situation. The data is an already collected material there interviews with abused children are done. The results presented consist of the previous research in the area where the empirical material analyzed from the developing ecological theory and based on children's different abilities to master life and then give an voice to the collected research. The results showed that if the violence in the family does not affect the child's sleep or the parents do not prioritize enough for the child to get the sleep he/she needs and that the child is not serious difficulty concentrating, it seems that children can use school to learn and enjoy this learning.
Effekten av öronproppar i intensiv- och postoperativ vård : en pilotstudie
Det är väl belagt att patienter postoperativt och inom intensivvården drabbas av en funktionell sömnbrist i form av störd dygnsrytm, stort antal uppvaknanden och rubbad sömncykel med underskott av djupsömn och REM-sömn. En delförklaring till sömnbristen är de generellt höga ljudnivåerna på intensivvårdsavdelningar. Syftet med föreliggande pilotstudie var att undersöka huruvida öronproppar kunde förbättra den upplevda sömnkvalitén för patienter inom intensivvård och postoperativt. Tjugotvå patienter från två intensivvårdsavdelningar, en hjärtintensivvårdsavdelning och en postoperativ avdelning deltog i studien. I interventions-gruppen sov elva patienter en natt med öronproppar och elva patienter som sov utan öronproppar utgjorde kontrollgrupp.
Chalmers oanvända datorkraft - Distribuering av arbete och energihantering med HTCondor
Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.
Brandgravar : Yngre järnålder i Broe, Halla socken, på Gotland : en studie i olika metoder, med fokus på kremeringen
This essay concerns the osteological cremated skeletal remains from Broe, Halla parish, Gotland of The Late Iron Age.The focus of this essay is to determine the position of the corpse on the pyre, whether the cremated bones were crushed after or prior to the cremation and if the individual was buried in the pyre. In addition the species, age, sex and skeletal abnormalities of the bones in question will be studied.The result of the research has yielded that the cremated bones did not need to be crushed to result in the small fragment sizes. Crushing of the bones may have happened during the cremation, this conclusion has been drawn through the comparison of a pyre experiment were bone fragmentation is evident with cremated foxes, and dogs in the cremation graves from Broe. The construction of the pyre and the position of the corpse could not be determined through colouring and fragmentation of the bones.The human's were commonly buried in the pyre, and in some cases it is possible that the "grave" in fact is the remainder of a pyre. The species found are dog, horse, cow, sheep/goat and bear.
Gäddan & fisket i Ringsjöholm : en osteologisk metodstudie i säsong & bevarande
This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.
Hästars aktivitet och liggtid på madrasserade gummimattor i box
Sleep is essential for all mammals and they all have different sleep patterns. Wild horses normally spend 2-8.5% of a 24-hour period in recumbent position while stabled horses lie down 11-20%. To fulfil the need of rapid eye movement (REM) sleep the horse must lie down with support against the ground for the head. The lying behavior can be affected by external stimuli such as age, food intake, bedding materials and if the horses feel safe or not. This study investigates the lying behavior of horses on different bedding materials; wood shavings and filled rubber mats (HIT SoftBed®).
Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :
Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.
Eutanasi : en skonsam död
This work is about euthanasia and how to use it on horses, dogs and cats.
A description for each animal is done, about when it is time, why, which methods can be used and who is allowed to use them, how and where it shall be done.
The methods we have concentrated on are:
- Chemical destruction and the most common drugs for euthanatize horses, dogs and cats.
- Physical disruption of the brain activity by a captive bolt, only for horses.
The captive bolt only makes the horse unconscious and must always be followed by cutting off the vena jugularis. Then the horse dies because of loss of blood.
No matter which method used for euthanizing, the animal must be declared to be dead by the operator before other measures. The testing criteria for death: muscle relaxation and cyanosis, cessation of reflex activity and pupillary dilatation, cessation of respiratory activity and cessation of all cardiac activity.
Att sova på sjukhus
Bakgrund: Sömnen har stor betydelse för återhämtning vid sjukdom och bevarande av god hälsa. Många gånger skiljer sig vårdmiljön från patienternas normala omvärld och möjligheten för inlagda patienter att påverka sin sovsituation är ofta liten.Syfte: Syftet med denna litteraturstudie var att belysa de faktorer som vuxna patienter upplever som störande för sömnen under sjukhusvistelsen.Metod: Litteraturstudien som genomfördes grundades på tolv utvalda vetenskapliga artiklar. Dessa artiklar granskades, analyserades och sammanställdes.Resultat: Studien visade att det fanns flera olika faktorer som patienterna upplevde som störande för sömnen under sjukhusvistelsen. Det visade sig även förekomma delade meningar kring hur mycket sömnen påverkats utav vistelsen på sjukhus. De faktorer som identifierades som störande för sömnen presenteras under följande kategorier: medicinska faktorer, omvårdnad & sjuksköterske faktorer, omgivningsfaktorer och personliga faktorer.Slutsats: Denna studie visar att den verksamhet som bedrivs idag och de bestämmelser som styr vården bidrar till att patienter upplever svårigheter att sova under sjukhusvistelsen.
Kromatinstabilitet som grund för kvalitetsbedömning av hingstsperma :
This study is part of a project to evaluate and develop metods to control the semen quality in stallions. The study was carried out in cooperation between SLU and Flyinge AB. The objective of the study was to analyse
-if there are individual differences in sperm chromatin integrety between different stallions
-if there is a correlation between subjectively evaluated sperm motility and sperm chromatin integrity
-if sperm chromatin integrity is changed after selection of the semen with a centrifugation method through the silica-spheres, gradient or a single-layer, i.e to use the chromatin integrity analysis as a method to evaluate the selection method.
The use of chilled transported semen has increased a lot during the last 10 years, especially among the Swedish warmblood breed. Because the foaling percentage has decreased with the increased use of chilled transported semen, there is a need to develop methods to control the sperm quality. Evaluation of the chromatin integrity could be one way to evaluate the quality of the semen.
Chromatin is the DNA in the nucleus of the sperm.
Religionsämnets värdegrund manifesterar det som redan har hänt : En jämförelse mellan läroplanerna Lpf-94 och GY 2011 i ämnet religionskunskap, samt hur detta uttrycks i olika läroböcker
This paper studies the fragmentation and reuse of early christian monuments ("eskilstunakistor") in churches in Östergötland during the medieval period. This is found to have been done in two stages. The first stage shows a collectivization of society. Within religion the change from ancestoral cult towards the saints' cult is important as the fragments are reused like relics. During the second stage the collectivization has been fulfilled, and the reuse is instead part of the christian churches' strategy for incorporating old powerful symbols from the landscape into their own church building..
Hur har natten varit? : Litteraturöversikt: Omgivningens påverkan på patienters sömn på sjukhus
SAMMANFATTNINGBakgrund: Delaktighet, vårdrelation och kommunikation är tre centrala begrepp inomhälso- och sjukvården. Detta med tanke på att det är tre faktorer som kan få patienten attpåverka dennes hälsoprocess samt att kunna trygghet. Syfte: Att belysa sjuksköterskansförutsättningar och hinder för att skapa delaktighet i vårdrelationen med patienter närsamma verbala språk inte talas. Metod: Studien utgår från sjuksköterskans perspektiv ochbaseras på en kvalitativ analys utifrån Evans (2002) litteraturstudie. Resultat: Det somansågs vara förutsättningar för delaktighet kunde vara tolkens närvaro för skapandet avdelaktighet i vårdrelationen.
