Delta X : Utveckling av värmeväxlare

Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..

Fenylbutazon - tillåta vid tävling?

Phenylbutazone has been discussed in the world of the equestrian sport several times and different countries have diverse opinions on its use in competitions. The progressive list that permits phenylbutazone with plasma levels up to 8 µg/ml was presented at the FEI General Assembly in November 2009. The list was voted to be accepted, but later several countries realized the consequences and after protests the list was rejected and is going to be discussed again at the FEI General Assembly 2010. In this literature study I have studied the relationship between the concentrations of phenylbutazone in plasma and the effects on lameness. The purpose was to establish whether the limit of 8 µg/ml phenylbutazone in plasma affects the equestrian sport.

Högkänslighetens spektrum En kvalitativ studie om behandlarens upplevelse av högkänslighet hos ungdomar samt den högkänsliga människans upplevelse av sitt karaktärsdrag

Syftet med studien var att undersöka hur behandlare upplever högkänslighet hosungdomar med psykosocial problematik. För att få en vidare förståelse förhögkänslighet ville vi även se hur personer med högkänslighet upplever sittkaraktärsdrag. Detta ville vi undersöka utifrån ett genusperspektiv. Studien baserades påtotalt tolv kvalitativa intervjuer varav åtta behandlare inom Hem för vård eller boendeoch Familjehem, samt fyra medlemmar från Sveriges Förening för Högkänsliga.Högkänslighet är ett karaktärsdrag hos 15-20 procent av befolkningen. Detta innebär attman är extra känslig för sinnesintryck och bearbetar dessa mer noggrant.

Verktyg för informationshämtning vid optimering av beredskap

This thesis describes a tool for data mining used to optimize ambulance preparedness. The goal with the tool was that it should be able to retract the information necessary to be able to analyze and calibrate the preparedness model used in the software ResQMap. ResQMap is used by SOS Alarm, who are responsible for the Swedish emergency number 112, as a decision support tool for ambulance operators. It is developed by Carmenta AB, who are the supervisors of the thesis work. Also, a minor study of the preparedness models variables has been performed in order to be able to evaluate the function of the tool.

Patienters upplevelse av livskvalitet i livets slutskede inom den palliativa vården : en litteraturöversikt

Background: Palliative care is a type of care, which does not cure but eases the suffering caused by the disease. The goal of palliative care is not to extend or shorten the patient's life, but to relieve pain and distressing symptoms and to promote the patients? quality of life (QOL). QOL can be understood as a subjective sense of happiness of existence, which means that the patient is experiencing life when her total life situation is consistent with her ??wishes.

Kopplingsbeslag för resårbottnar

The project has been implemented in collaboration with Carl-Johan Lundberg on Deltagruppen Ltd in Jönköping. Problem introduction comes from Carl-Johan's own experience from the hotel sector. The problem that all hotels has is that they sell two products, i e. simple - and double rooms. Persons that travel in companies do not desire always to share bed.Focus in the work is to develop a product that holds together two simple beds and forms double bed, concurrent that it goes that converters to two simple bed without needing to disassemble the product and be done invisible.

Den ekonomiska tillväxten : en redogörelse för pessimistiska och optimistiska synsätt

The economic growth we have experienced the last century is based on limited natural resources. Whether these resources will last for a further economic growth is widely debated. Pessimism and optimism have each been influential philosophies in debate whose opinions can be conceded as two opposing opinions. In this paper we have analyze these opinions from an economics perspective. To study this further, the construction and meaning of the pessimistic and optimistic arguments have been applied implicitly on the Leontief production function and the Solow growth model.

Improvement of positive strand assay used in detecting positive and negative RNA of hepatitis E virus

Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).

Skuggvävens effekt på fryslagrade täckrotsplantor av tall (Pinus sylvestris) i upptiningsstadiet :

This project was an assignment by Sveaskog and Svenska Skogsplantor. The purpose was to study the effect of protective fabric on the thawing stage of frozen pine seedlings. The function of the protective fabric is that it should protect the seedlings against strong sunlight and create an even temperature inside the boxes containing the seedlings. The result has shown that there was no statistically significant difference when the protective fabric was used or when it was not used, although this was probably due to the weather conditions. The study was carried out under cold and cloudy weather conditions and probably would have given other results if there had been more sunny days with a higher ambient temperature.

En nutida analys av reseguidehemsidor

In this research our goal is to conclude the aspects of interactivity which can prove to be important during the creation of a website. The focus in this essay is websites functioning as travelingguides, because we live in a time of traveling, experiance and learning. How can an analyzing method of websites be shaped? What can an analyze of interactivity on current travelingguides provide for recommendations by the creation of interactive travelingguides? The analyzingmethod is based on three shapingmethods and a poll that was answered by both national and international people. The analyze gave us quite clear results, if you follow the basics of Use Case, Personas, Usability and design, the website will have a bigger chanse of attracting people than if it doesn't..

Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier

This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.
