The aim of this study was to describe the mental and social causes to obesity among children and adolescents, their consequences and what preventive interventions that are used. The method used by the authors was to search for scientific articles in the database Medline, using the keywords: obesity, overweight, child, body image, social, family, school, depression, nursing, quality of life, social support, prevention and support. The study was performed as a literature review, with a descriptive design, and the result contained 22 scientific articles. The main result of this study showed that obesity among children and adolescents is not only an individual problem, it affects the whole family. The main causes to obesity among children and adolescents are the socioeconomic status of the family, their lifestyle, and even gender to a certain degree.

Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

Under de senaste åren har det visat att folsyra har en koppling till neuralrörsdefekter (NTD) hos foster. Under graviditeten ökar kravet på folsyra på grund av tillväxt av livmoder, placenta och foster. Syftet med detta arbete var att ta reda på folsyrans effekter och bieffekter. Att redogöra de vetenskapliga belägg som finns för folsyrans skyddseffekter mot missbildningar och vilka rekommendationer av folsyratillskott som ges till de fertila kvinnorna i barnafödande ålder. Metoden som användes var att söka och granska vetenskaplig litteratur i form av artiklar från databaserna PubMed, SveMed+, Svensk MeSH, Google Scholar och Libris.

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Syftet med denna studie är att titta på det vi vet om dopamins roll i aptitreglering idag, både generellt och med ett veterinärmedicinskt intresse specifikt på hund. Dopamin är transmittorsubstans i flera nervbanor i hjärnan och dess frisättning har traditionellt kopplats starkt till att positivt förstärka nyttosamma upplevelser eller handlingar i det som kallas kroppens ?belöningssystem?. I relation till föda och födorelaterade beteenden har man dock på senare tid sett att dopamin har en bredare betydelse än att enbart förstärka själva födointaget. I litteraturen syns därför ett fokusskifte mot ett vidare perspektiv med hänsyn till dopamins alla, nu kända roller ? något som väckt insikten om det dopaminerga systemets komplexitet och frågan om det ens är möjligt att få en helhetsbild över alla dess funktioner. Denna litteraturstudie har undersökt delar av ett stort litteraturmaterial fram tills idag och konkluderar att trots mycket forskning är dopamins exakta funktioner i aptitregleringen fortfarande inte klarlagda utan det verkar fortfarande råda ovisshet och oenigheter.

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

The Landscape Architecture Program at SLU, Ultuna provide several design courses. Within these courses, students are mainly introduced to one type of design process, a process based on the specific site and its conditions, known as Genius Loci. This report presents a course and a design methodology from Cornell University which aims to provide students with tools for a more conceptual way of thinking about design and architecture. The design method is presented in two stages. First an introduction to the course description and objectives.

Today evidence exist that environmental chemicals deteriorate male sperm quality and that testicular cancer is increasing. Bisphenol A (BPA) is a chemical with estrogenic effects used in the manufacture of polycarbonate plastic and are found in, for instance, plastic boxes, feeding bottles and food containers. Much of the research on how men's reproductive ability is influenced are performed on rats. This review article complies how male rat reproduction is affected by BPA as a model for humans. Studies have investigated how sperm are affected, hormonal changes during reproduction and how reactive oxygen species (ROS) affects sperm.

Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.

SammanfattningSyftet med den här litteraturstudien var att ta reda på vad det finns för möjligheter och svårigheter att producera ål i fångenskap. Med nya hållbara metoder att föda upp konsumtionsål skulle utfiskningen av glasålar minska i världen och man skulle kunna fortsätta äta den goda rökta ålen med gott samvete.Det finns välutvecklade metoder för att inducera könsmognad hos han- och honålar. Detta utförs genom att injicera hormoner och man kan därför fråga sig om det är hållbart i en produktion för framtiden. Efter kläckning av larverna finns flera viktiga faktorer att ta ställning till, så som utfodring och optimal hållning av ålarna. Även ägg- och mjölkekvaliteten spelar en stor roll när det gäller att hålla ålarna vid liv.Abstract The aim with this study was to find out how far we have come to develop reproduction strategies in eel culturing.

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

The common warthog (Phachocoerus africanus) is a relatively long-legged pig with noticeable curved tusks, a short neck and three pairs of facial warts. It has four recognized subspecies. The common warthog is a non-migratory ungulate living on the African savannah. It is a hindgut fermenter and predominantly dependent on high-quality foods. It prefers open areas for grazing but use bushes for cover.
