Kan total enteral nutrition ersätta steroidbehandling vid pediatrisk Morbus Crohn?

Sahlgrenska Academyat University of GothenburgDepartment of internal medicine and clinical nutritionAbstractTitle: Can exclusive enteral nutrition replace steroid treatment in pediatric Morbus Crohn?Author: Hanna Rymark Lehnér and Josephine PetterssonSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012Background: Morbus Crohn is a chronic inflammatory bowel disease which periodically causes great suffering for the patient. There is solid scientific evidence that treatment with steroids effectively induces and preserves remission. However, side effects are many and a great risk for stunted growth and skeletal development exists in children. A widespread view is that exclusive enteral nutrition is as effective as steroids in pediatric Crohn´s.

MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2

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.

Man har ju i alla fall tak över huvudet : En kvalitativ studie om natthärbärgets effekter på hemlösas självupplevda psykosociala hälsa

This is a qualitative study, whose purpose is to examine if night shelters effects homeless peoples self-perceived psychosocial health.

Hantering av negativ eWOM på Twitter - Ett sätt att skapa kundrelationer

Consumers are facing a wide selection of brands trying to get their attention. An increasing amount of corporations are incorporating non-traditional media in their marketing strategies as an attempt to build relationships with their customers. However, along with the new opportunities to enhance consumer emotions about the brand, social media has brought along new risks for corporations to face. This paper investigates the consequences of different ways of handling such electronic word-of-mouth (eWOM) crisis on Twitter. Furthermore, we investigate potential differences depending on the credibility of the source that sent the message.

Stranden och det främmande : En undersökning av ?den Andres? roll och tematisering i Alex Garlands The Beach

In this essay I point out that the presence of  ?Otherness? plays a key role in the novel The Beach by Alex Garland, and that the text relates to a colonial literary tradition. I?ve mainly used the distinction of Otherness and cultural representation presented by the postcolonial theorist Edward W. Said to guide me.

Genomgång av kemikalieförteckning som exempel på uppströmsarbete : en identifiering av utfasningsämnen i spillvattnet

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.

Dark Side of Wonderland : en kort 2D-animation med syfte att väcka intresse för en online serietidning

My objective for this project was to create a short but thrilling 2D-animation intended as promotion for an online comic book. The purpose of the project was to learn more about animation and graphics, to further my artistic skills and to learn how to work in Adobe After Effects. I also wanted to learn more about scheduling, project methods and how to handle stress. During the ten weeks of the project I have created the story, the storyboard, the character design, the backgrounds and the animation. The voice over was recorded with the help of a fellow student who also made the music and the sound effects.

Mätning av Emissioner från en Diesel Motor under Transient Driftförhållande

Transient driftförhållande blir allt mer intressant för forskare och tillverkare och de största svårigheterna är att minska emissionerna utan att påverka bränsleförbrukningen eller motorns respons vid gaspådrag negativt. Huvudmålet med det här examensarbetet var utvärdera olika metoder för att mäta NOx och antal partiklar med hög tidsupplösning för att möjliggöra studier av emissioner under transient driftförhållande.I arbetet har en Horiba MEXA 120NOx NOx-sensor studerats med avseende på linearitet, mätsäkerhet och responstid. Försök för att öka noggrannheten har också gjorts genom att kompensera för varierande skalfaktor för utsignalen och för responstiden.Ett spädsytem har arbetats fram för att ge hög tidsupplösning och god repeterbarhet. I detta ingick en Rotating Disc spädare och en två-stegs Dekati spädare. Spädsystemet var kopplat till en TSI Ultrafine Condensation Particle Counter 3025 A (CPC) och var nödvändigt för att hålla koncentrationen inom det mätbara området.

Visualisering av elanvändning i kontorsfastigheter : Utveckling, implementering och utvärdering av visualiseringsverktyg för minskad elanvändning

This thesis examines the effects of electricity visualization in an office building. The subject was investigated through the creation of a web based visualization tool that was made accessible to the about 1500 employees in a large office building. The visualization was available for three weeks. During this period interviews, user studies and observations took place in order to evaluate what, if any, effects the visualization had on the attitudes and behaviors in the office. Electricity use data was collected and analyzed to see if the project had a statistically significant effect on the electricity consumption in the office.The results from the interviews and the data analysis indicate that no reduction in electricity consumption took place, and a number of factors that could increase the chances of success were identified.

Mindfulness as business : Vad några mindfulnessinstruktörer anser att mindfulness kan tilllföra arbetslivet

The purpose of this paper is to critically examine and question the use of mindfulness in the workplace. Mindfulness in the workplace can be understood as an organization recipe and is now a so called trend. We believe that there may be an issue of how mindfulness at work is advertised when it is described in such a way that it could be the solution to many organizational problems, such as reducing stress, increasing efficiency, creativity and productivity. To get a better understanding of what mindfulness is and what it can bring to a stressful work, we conducted semi-structured interviews with four mindfulness instructors. We analyzed the interviews from a theoretical analytical framework consisting of both a constructivist perspective and a power perspective.
