Monte Carlo-simulering av tillverkningskostnaden

DPM is a manufacturing company within the metal cutting industry. A number of years ago there emerged a desire to make statistical calculations for its production. Until today, the company has not done any post-calculations, which means that they have based their cost calculations and sales prices on precalculated costs. The absence of post-calculations leads to lack of cost-consciousness that is

Produktions- och konstruktionsanalys av acceleratortekniska komponenter

A particle accelerator consists of a large number of components, which among other things includes several acceleration modules, which consists of one or several cavities. A cavity is a complex and essential part in the accelerations process and is usually made of oxygen-free copper (OFC) or niobium. These two materials are special when it comes to metal cutting, it´s hard to find information abou

Development of an in vitro assay for analysis of cellular uptake of nanoparticles

Metodutveckling för analys av cellulärt upptag av nanopartiklar Cancer är idag en utbredd sjukdom som tusentals människor världen över diagnostiseras för dagligen. Möjligheterna att få en korrekt behandling ökar om tumörer upptäcks i ett tidigt skede tidigt vilket ger en större chans att tillfriskna. Men detta har visat sig vara en utmaning då nuvarande metoder som används inte är av tillräckligAbstract MRI, magnetic resonance imaging, is used for disease detection such as assessing blood flow, detecting tumours and diagnosing many forms of cancer. Contrast agents are chemical substances that increase the MRI sensitivity. One class of contrast agents are the so called nanoparticulate contrast agents. Since tumour-associated formation of new blood vessels often results in highly permeab

Swedish Stories of the Neighbour Across the Baltic Sea: A Narrative Media Analysis of Swedish Reporting on Lithuania

This thesis identifies ten main narratives related to Lithuania in the reporting of five major Swedish newspapers between 2010-2012, and investigates how these narratives have been discursively constructed and why they might have been chosen to serve as a frame of reference for Swedish readers. Through narrative analysis and a theoretical framework including the concepts of ‘narrative’, ‘collectiv

State-owned enterprises' operating efficiencies does percentage of private share matter?

What kind of influence does percentage of private share have on state-owned enterprises’ operating efficiencies? The thesis studies on the correlation between percentage of private share and SOEs’ operating efficiency in China. By analyzing both input and output side of SOEs’ performance (i) theoretically, based on previous studies, and (ii) empirically, through data bivariate analyses and variabl

The Determinants of Micro Saving

It is more difficult for the poor to save money than for the wealthy. The poor have no institutions to help them such as state pensions and they are left to fight their personal short comings themselves. One consequence is that the poor save under their ability. Savings is important to respond to changes in the environment and to avoid incurring debt. Two of the behavioral obstacles the poor face

Certifieringar inom byggsektorn

Construction business is responsible for a large portion of the world's emissions of greenhouse gases. As part of the work against this, environmental certifications has become more and more common. This is partly because consumers have been more willing to pay more for products or services with low environmental impact and this has had a major impact on the construction industry. In this stud

Hur en leverantör till byggindustrin kan bidra till en miljöcertifiering enligt LEED

Syftet med detta examensarbete är att undersöka vad en leverantör till byggindustrin kan göra för att deras kunder ska uppnå en miljöcertifiering enligt LEED. Studien kan delas upp i tre delar. I den första delen har vi fördjupat oss i de miljöstyrmedel som använts i Sverige idag såsom olika miljöcertifieringssystem och miljöledningssystem. Den andra delen beskriver vilka produkter en leverantör t

Utveckling av balkramskonstruktion för pumpstationer till kylsystem

ABB Swedewater has designed and manufactured pump stations and cooling systems for many years. During this time, several different designs on frames have been developed. Most of these are based on welded steel profiles which are then painted. For smaller pump stations bolted profiles and bent plates are used. Today there is a need to find a more modern design that reduces the design time in the pr

Mapping Potential Distribution for the Endangered Wild Asses of Asia, Equus hemionus

Popular science summary: Potential Distribution for the Endangered Asian Wild Ass Over the past century, large mammals have been globally under increasing pressure of humanized landscapes. Since extirpations of large herbivores are likely to have complicated consequences for the entire ecosystem, their conservation is a priority. With almost 81% threatened species, Perissodactyla (odd-toad ungu

The swedish white stork reintroduction programme

Popularvetenskaplig sammanfattning: Storkprojektet i Skåne – nutid och framtid Den vita storken (Ciconia ciconia) har varit utdöd i Sverige sedan 1954. Orsaken till storkens försvinnande tros ha varit en kombination av utdikningar av våtmarker, ökad dödlighet samt en generellt nedåtgående trend hos storkpopulationerna i övriga Europa. Sedan 1989 pågår ett återintroduceringsförsök i Skåne. Genom Abstract: In 1954 the last breeding attempt by the White Stork (Ciconia ciconia) in Sweden failed and the species was declared extinct from the Swedish fauna. Reasons for the extinction are thought to be a combination of issues such as habitat conversion, increased mortality and an overall decline of the European White Stork populations. Since 1989 an ongoing reintroduc-tion programme for the Whi

Parallellhandel och hur den påverkar läkemedelspriser - Marknadsdynamiken mellan parallellimportör och originalfabrikant

In a market with homogeneous products and no barriers to trade, arbitrage, in the form of parallel imports of pharmaceuticals, is expected to lead to a price convergence in the market as a whole, preferably downwards, as an effect of competitive behavior between the parallel trader and the pharmaceutical producer. Such an effect on prices have however only sparsely been shown in previous research,
