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.

During the last decades the questions about environment and social ethics, so called Corporate Social Responsibility (CSR), have increased in importance. It is in the business world highly important for the corporations to show the public that the company care about these questions. A common approach nowadays is to outsource productions to other countries resulting in that suppliers have a great part of the work with CSR. CSR as a trend is a rather new phenomenon, and therefore interesting to see how the corporations handle these questions and how the approach looks like. The purpose with this study is to show how corporations which are recommended by CSR organizations for their handling regarding these questions approach CSR and how the work look like in the supply chain.

Demands on businesses are constantly increasing and the competition in the market-place is becoming ever tougher. To gain the long-term confidence of customers, not only the best businesses, but also the best supply chains are required.Volvo Cars is experiencing a changing competitive situation and their retailers are having trouble stocking the right spare parts. Shorter product life cycles and the growth of Volvo?s product program result in an increase in the number of spare parts to be stocked. In order to adapt to market trends and meet customer demands, Volvo has developed the LDC model, establishing a number of regional warehouses in strategic locations in Sweden, de-signed to supply spare parts to the regions? retailers through so-called Vendor-Managed In-ventory (VMI).The purpose of the study is to examine Volvo personbilar Sverige?s (VPS) motivation for a modified customer-service strategy through LDC.

A study around some fourteen and fifteen year old boys, who are interested in reading. It is about their reading and library habits, what has created their interest and where they acquire access to literature. A certain amount deals with the habits of the boys? school-friends in this subject. The result compares with earlier made reports.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Att upprätthålla en effektiv konkurrens är något som EG-rätten syftar till. Genom artikel 82 i EG-fördraget förhindras dominerande företag att via ensidiga förfaranden utestänga konkurrenter eller begränsa konkurrensen. Det finns flera sätt, för ett dominerande företag, att påverka konkurrensen negativt och därmed göra sig skyldigt till missbruk enligt artikel 82. Ett förfarande som under vissa omständigheter kan anses som missbruk är att leveransvägra för att stoppa eller begränsa parallellimporten. I denna uppsats diskuteras och analyseras det om under vilka förutsättningar en leveransvägran kan anses som ett missbruk av en dominerande ställning.

Logistics and supply chain management in the construction sector is an area with great potential for improvements. Today, a lot of the workers time is spent on non-value adding activities. Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.

Denna rapport beskriver ett projekt utfört på Bjurab Sweden AB i Halmstad. Syftet med projektetär att finna och åtgärda de faktorer som sänker tillförlitligheten i affärssystemets saldo, samtskapa bättre kontroll över olika artiklars placering på olika lagerplatser. Anledningen till att företagetvill genomföra detta projekt är att deras inköpsarbete idag blir lidande av att saldot i affärssystemetinte stämmer. Detta i kombination med att de har dålig kontroll på var materialet ärplacerat leder till att de lägger mycket tid på att leta efter material, och att inköp ibland sker såsent att produktionen tvingas stanna upp på grund av materialbrist.Arbetet inleddes med kartläggningar av informations- och materialflödet, och insamling av historiskdata från affärssystemet. Detta kompletterades sedan med intervjuer med de berörda i företaget.Genom detta upplägg studerades situationen först på lite avstånd med syftet att hålla objektivitetenhög, och i den efterföljande intervjun tilläts sedan objektiviteten sjunka något för attkunna komma riktigt nära det undersökta.

This thesis work has been performed at Volvo Aero Corporation in Trollhättan, at the department of ?hot structures? involving aircraft engine GP7000. The purpose with the study was to investigate the possibility to reduce size of the forging of flanges on the rear turbine frame when purchasing. Thereto examine the parameters that affect the flanges motion during the manufacturing process. The goal was to provide Volvo Aero with foundation to later bring in slimmed forgings.

The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.
