Background ? The last 20 years healthcare has been facing increased demands on efficiency and increased customer satisfaction. This despite reduced resources and increasing demand. These demands are presents in all departments within healthcare organisations, including medical laboratories that currently receive an ever-increasing number of remittances. Laboratory flows are quickly becoming overloaded with samples and related Materials.
Radonfritt boende : Stegen till att eliminera radongas med rätt Grundläggningsmetod
People who live in northern part of the world spend much more time indoors than those who live in warmer countries. In addition that home should be safe, it should also protect one against heat, cold, sunlight and pollution. The indoor environment is affected by installations, material and how the building is formed. Those anomalies that are visible, felt or smelled can be noticed and be rectified. But it?s much more difficult if these abilities are missing.
Utveckling av ett lyftverktyg för skivformade produkter
Under höstterminen 2013 har Stefan Erlandsson och Louise Andersson, designingenjörsstudenter på Högskolan i Skövde, utfört ett produktutvecklingsprojekt i samarbete med entreprenören Lars Willebrand. Målsättningen för projektet var att utveckla ett lyftverktyg som ska komplettera Willebrands produktserie bestående av; travers, svängkran, plåtbyrå och lyftverktyg. Lyftverktyget ska vara anpassat för att användas i kombination med en plåtbyrå, vilket innebär att det kommer användas till att lyfta material från höga och låga höjder. Lyftverktyget måste därmed konstrueras i syfte att underlätta för användaren och undvika arbetsskador som kan uppstå vid dessa lyft. Lyftverktyget ska även kunna anpassas till kunder som endast avser att lyfta skivformade produkter i midjehöjd.Projektet inleds med en förstudie där mycket fokus läggs på ergonomi och användaren.

Helsingborg ? Ängelholm, en jämförelse mellan kommunernas friskvårdsarbete för sina läraranställda.
AbstractAuthorJohanna Rahl and Marie Johansson.TitleHelsingborg-Ängelholm, a comparison of the work of the municipalities regarding self generated health care activities for employed teachers.ContentToday you pay more and more attention to self generated health care. Political decisions affect the social development and thereby also conditions for people to feel healthy. As the municipalities are working with its inhabitants they are an important part of the self generated health care activities. The most part of our life we spend in school or at work and this is the reason why these places are the most suitable to create healthy people. From these thoughts we created the following aim of the study:?The aim of this study is to investigate what kind of work regarding self generated health care that is performed by the municipalities of Helsingborg and Ängelholm towards the employed teachers and how the teachers apprehend this work.
Krav och önskemål på skogsbruksplanen : förbättringspotential med laserskanning
In 2009 The National Land Survey of Sweden, Lantmäteriet, commenced a project intended to provide a new digital elevation model (DEM) of Sweden. The method chosen for the project was airborne laser scanning (ALS). In addition to information about the land surface the project will also provide information about the forest, this as a by-product. This data can be used to estimate forest variables such as height and volume. The estimates are often more reliable than what is standard today.
This study is based on interviews with employees and members of the forest owner association Södra in southern Sweden.

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.
Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
Effektivisering av marina containerflöden : en fallstudie på Bertling
Logistics is an important concept in the organizational context in which the planning of flows, services and products are treated. Logistics handles supplier management, supply of Materials, production and distribution. The distribution of goods can be managed with different types of transportation depending on price and time aspects. The lowest transport cost for larger amount of goods is by maritime shipping. A common carrier used in transportation of goods is a standardized ISO- container.
Livscykelanalys av flerbostadshus ? energieffektiviseringsåtgärder för minskade koldioxidutsläpp
The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.
En ökad kontroll av tillverkningsresurser i samband med CAM-
beredning
Sandvik AB grundades 1862 av Göran Magnus Göransson som var den första i världen som lyckades framställa stål enligt Bessemermetoden. Idag, nästan 150 år senare, har Sandvik AB 44 000 anställda och är verksamma i 130 olika länder världen över och har en omsättning på närmare 72 miljarder SEK. (Sandvik) Sandvik är indelat i tre olika affärsområden: Sandvik Tooling, Sandvik Materials Technology och Sandvik Mining and Construction, vilket också är det område detta examensarbete berör. En del av produktionsberedningen av produkterna, CAM-beredningen, är att skapa de verktyg som produkten i fråga skall bearbetas med. Verktygen hämtas i dag från olika platser (databaser, mallar) och används sedan i beredningen för att simulera bearbetningen av produkten.

Hackelselängden beroende av skördemetod :
The conditions for a good silage process start with good wheather and choice of crop, then choice of harvesting machinery. The shorter and more mechanically treated crop, the better quality of the forage. (Pauly 1994). This study has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces.
Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator
Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
Sustainable business practices : a review of eco-efficiency
The current demanding business environment requires corporations to act fast in finding effective solutions to problems given the myriad of challenges they face (Dyllick & Hockerts, 2001). The challenges include the impact of climate change on business practices, natural resource consumption, chemical pollution, technological change etc. Moreover, the forces of globalization, heightened concerns about the deteriorating quality of the physical environment and increased stakeholder power are also increasingly having a real influence on business practices (Rainey, 2008).
Since 1992, the World Business Council for Sustainable Development (WBCSD) has encouraged the adoption of the concept of ecological efficiency (eco-efficiency) to support business efforts aimed at addressing some of these challenges. The aim of eco-efficiency is to reduce the amount of energy and Materials used in production processes to achieve economic and environmental benefits (WBCSD, 2000).
