Energimässig jämföelse med investeringskalkyl av två förskolor

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

Krafter på rörsystem vid transient flöde : En jämförelse mellan RELAP5 och Fluent

At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.

Luftföring i operationsrum. Visualisering av olika luftföringsprinciper i modellskala.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Effektivisering av ventilationsprojekt : Bravida Filial Uppsala

In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.

ENERGIEFFEKTIVISERING AV VENTILATIONSYSTEM I AITIK, BOLIDEN

Aitikgruvan är Sveriges största dagbrottsgruva som bryter kopparkis. Kopparkisen bryts i dagbrottet och transporteras under jord i ett underjordsortssystem till ett anrikningsverk. I ortssystemet finns ett ventilationssystem som i dagsläget styrs utan hänsyn till ventilationsbehovet i orterna. Boliden har för avsikt att göra energibesparingar inom dess verksamhet och ett sätt att göra det är att styra ventilationssystemet i ortssystemet efter behov. För att styra ventilationen skall applikationen ?Ventilation on demand?, en produkt utvecklad av ABB, implementeras i det nuvarande styrsystemet 800xA.

Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

Kroppsideal hos unga kvinnor i åldern 15-25 år : En kvalitativ studie av unga kvinnors syn på kroppsideal

In this essay, I have interviewed six young women about their views on body image and how their views are affected by their surroundings, massmedia and social media. Also the relationship between body image and eating disorders is relevant in this context and has a part in the study. The purpose of this study is to build an understanding of how young women relate to the body ideal that exists around them. Theoretical auxiliary tools used are George Herbert Mead's theory of the generalized other, Erving Goffman's theory of dramaturgical perspective and impression management, and Du Bois's theory of double consciousness. I have also used two scientific articles to get a deeper understanding of the subject.

Nya kriser, gamla källor : en kvantitativ studie om nyhetskällor på expressen.se och dn.se under katastrofen i Japan

In a press release from the Swedish church it says that the pressure from people who are in need is increasing on the deacons in Sweden and that it?s getting higher each year. This study contains the search of knowledge about the deacons of the Swedish church, if they actually feel an increasing pressure and in what way, how they are handling the possible pressure from people in need, if that pressure is too high and if the deacons feel that they can assist the people seeking their help. The study also aim to provide more knowledge about the deacons experiences of the opportunities and boundaries (or obstacles) they meet in their line of work and how they handle the boundaries when/if they can?t provide the help that the people need.

The impact of the EU Timber Regulation on the Bosnia and Herzegovinian export of processed wood

Illegal logging and its related trade is of great concern around the world. The European Union Timber Regulation (EUTR) is a regulatory approach by the EU to prevent illegal timber and timber products to be placed on the European Union inner market. This means the regulation affects both actors in the member countries as well as the actors exporting timber and timber products to the EU from non EU member countries. This study aims to study the implementation process of the EUTR in Bosnia and Herzegovina (B-H), and its preconditions. Institutional theory is used to understand and explain how the EUTR affects B-H organisations? business environment, and how the organisations choose to respond to the EUTR.
