Gymnasieungdomars hälsa : En jämförande studie av unga migranters och inrikesfödda ungdomars hälsa
Aim: The aim was to investigate and describe, how students on high school level in Kronoberg county self rated their health with relation to irritation, nervousness/anxiety insomnia and gender. An additional aim was to investigate if there are differences between students born in Sweden by Swedish parents, students born in Sweden by foreign-born parents and foreign-born students. Methods: A quantitative method was used to analyse data gathered from students (n=1936) on high school level in 2006. All statistical analyses were made with help of SPSS V-12. Finding: The findings showed that most of the students self rated their health as ?good?, however migrant students self rated their health as ?not so good? and they had more problems with insomnia. The overall findings showed gender differences. Particularly, foreign-born girls self rated their health as ?not so good? and reported more problems with insomnia. There was no divergence between the groups regarding irritation, nervousness/anxiety. Conclusion: School nurses and health workers must have deep knowledge about differences in gender, self- rated health and insomnia when they work with public health.
Detaljhänsyn efter slutavverkning : kvantitet och inverkan på framtida produktion hos SCA i Västerbotten
According to FSC (Forest Stewardship Council) shall at least a mean of 10 trees per hectare including riparian zones and other areas with high biological values be left in final felling. In addition large clear areas should not be created and all retained trees with high environmental value shall be spared. To leave trees in final felling means a lower cutting volume and hence a lower income from the cutting, but it also means that the production in the next generation becomes less because of competition. The aim of this study was to evaluate the effect retained trees have on the production in the new generation of forest, and to investigate if there is any way to lower this effect. The environmental care has also been estimated by the amount left in final felling.
Ventilhus för salivsug i dentalutrustning
The purpose of this work is to find out if the suctionvalve to the
salivaejector for dental equipment in a simple way can be improved or if a new
design is needed. The result of the examination of the suctionvalve shows that
the friction between the piston and the seal is high and that this causes the
valve in a few cases sheaves. The study concluded that only small changes in
material or detail, improve the component..

Molekylärgenetisk analys av dilaterad cardiomyopati hos hund :
Canine dilated cardiomyopathy (DCM) is a disease with high morbidity and mortality and with a high prevalence in certain breeds. Predominatly large breeds are affected, such as Great danes, Newfoundlands, Deerhounds and Dobermanns. One exception is Cocker spaniels, where both American and English Cocker spaniels are affected in a quite high frequency.
Cardiomyopathy is characterised as a disease that affects the myocardium and gives an impaired heart function. To diagnose DCM following criteria have to be observed:
1. Dilation of the left ventricle.
2. Reduced systolic heart function.
3. Increased sphericity of the left ventricle.
To be certain of the diagnosis, alternative reasons for the symptoms such as lung- and heart diseases with other etiologies have to be excluded
Two different types of DCM have been found upon histological examination.
Sensory nerve conduction studies in young adults for the expansion of a reference material
Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.
Energikartläggning hos RostiGP i Gislaved
In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.
Vilken nutritionsbehandling har bäst effekt på tillväxten hos barn födda för tidigt och/eller med låg födelsevikt?
Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: ?What nutrition therapy has the best outcome on growth in preterm children and/or children born with low birth weight??Author: Josefine Nyström and Rebecca HammarSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2013Background: There is a number of reasons why a child is born preterm and with a low birth weight, for instance if the mother is underweight, smoking or exposed for malaria. The negative consequences of being born preterm or with a low birth weigth are many, both on long and short term. According to the WHO preterm birth is the most common direct cause of infant mortality. By providing the right measures in time when it comes to nutrition the mortality can be reduced considerably.Objective: To examine and summarise the scientific ground when it comes to the best nutrition therapy for preterm children and children born with a low birth weight.Search strategy: A systematic literature search was done in the databases Pubmed, Cohrane and Scopus.
Konstruktiva och destruktiva former av språklig kommunikation i moderna arbetsorganisationer : - En teoretisk undersökning med kompletterande fallstudier av Leksands vårdcentral och Mora vårdcentral
A main aim with the essay ?Constructive and destructive forms of language communication in modern work organizations? is to try to develop methods which can be used to measure and classify different forms of language communication. Methods that hopefully also can be used for analysis of in which ways dominating language communication forms affects employees health in modern work organizations.Quantitative methods have chiefly been used in the essay. A questionnaire study based on sociological research and psychoterapeutic research and practice has been used to collect data around communication in two work organizations (community health centers). Then communication has been classified in two main forms: constructive and destructive language communication.Results in the essay indicate that there are tendencies to links between high illness-absence and destructive communication in a work organization.

Gestaltningsförslag för Norbyvreten : från kvarterspark till stadsdelspark
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
EN JÄMFÖRELSESTUDIE AV PLAST- OCH GLASHEMOCYTOMETRAR FÖR BERÄKNING AV BLODCELLER I VENÖST OCH KAPILLÄRT HELBLOD
Hematology-instruments that analyze blood cells can at specific cases
be followed by manual counting with a hemocytometer. The plastic hemocytometer which has a fixed coverslip and is assigned for disposable use, appears to reduce the problems arising from the use of the traditional glass hemocytometer, for instance coverslip-application difficulty and dust particles. Capillary whole blood sampling may be useful for patients at the emergency department and in addition, a smaller volume of blood is taken compared to venous blood sampling. This study will focus on the platelet- and leukocyte count (PLT and WBC) in venous and capillary blood, in order to compare the plastic- and glass hemocytometers with Sysmex XN-2000 (Sysmex Corporation, Kobe, Japan), and verify if capillary whole blood sampling can be used for the measurement of these hematological parameters. 30 subjects donated both capillary- and venous blood samples and these blood samples were analyzed with glass- and plastic hemocytometers with Sysmex XN-2000 as the reference method.
?Tala är silver??: En undersökning av användarrecensioner på webben och på biblioteket
The purpose of this bachelor thesis is to examine reviewswritten by users in library online catalogs, online bookstoresand on the web community LibraryThing, in order todetermine whether there are any differences in the way usersreview books, and whether these differences might explainwhy libraries experience difficulties in getting their users toreview books. At the core of web 2.0 and library 2.0concepts lies the thought of user participation, and largerlibraries have sought to implement systems for reviewingand tagging items in the catalog in ways similar to onlinebookstores and other websites.By analyzing the contents of user reviews, however, thisthesis shows that users express themselves differentlydepending on what kinds of literature they review, and inwhat context. Most notably, user reviews of ?the Classics? orcanonized literature recognizes the high status of suchliterature, while users reviewing popular fiction expressthemselves in a way that admits that the reviewed titles areconsidered less valuable. There are also signs that booksreviewed at online bookstores are seen as products ormerchandise, while the reviews at the library to a greaterdegree treat the books as works of literature.The conclusion reached in this thesis suggests that there maybe a relation between the image of the library as a defenderof high culture and the perceived status of literary works,causing users to become hesitant to review books, feelingthat they do not have the knowledge to describe or reviewthem ?correctly?..
Våga Vara Annorlunda?: En uppsats om hur produktengagemang och motivation påverkar inkongruent marknadskommunikation
To be seen is essential. Presently, the marketing of different well-known brands within the same product category is done with little variation. To marketing professionals, this creates an opportunity to market products in an unexpected way. The use of incongruent market communication and by creating a discrepancy between a well-known brand?s advertisement and brand scheme, which is already established in customers? minds, is one way to be different.
Interorganisatorisk styrning av leverantörsrelationer inom lågprismodebranschen: -En fallstudie av lågprismodeföretaget BikBok
This thesis concerns the control of outsourced interorganizational buyer-supplier relationships in the low-price fashion industry. A qualitative case study has been performed on two supplier relationships of a low-price fashion company. By identifying specificities of the industry and relating them to control problems and their implications on control solutions, the thesis has established a relation between industry specific characteristics and the way companies in the industry control their supplier relationships. The analysis is based on a theoretical framework created by Dekker (2004). Amongst other factors, the difficulty to define, quantify and measure the design variables of a fashion good, the high heterogeneity between individual products and the difficulty to predict the trend based demand, create high coordination requirements as well as appropriation concerns solved through extensive formal control.
