Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Konstruktion och utvärdering av diplexer

The report descripbs how a diplexer for a hybrid analog/digital filterbank has been constructed and tested. A diplexer divides the frequency band into two different bands that do not who doesn't overlapp each other. The sampling rate for the two ADC:s is 80 Msps, and therefore it is advantage to have zero at 80 MHz. The reason for this is that a proposed class of hybrid filterbanks with very good quality requires a zero at or close the sampling frequency to work well. The diplexer was made in three versions.

Motiven bakom en investering i crowdfunding

It is well known that small businesses and entrepreneurs in the initial phase has difficult to gain access to external capital and bank loans. With the background of the problems that entrepreneurs face when they ask for capital has since the financial crisis the phenomenon of crowdfunding developed and evolved. Crowdfunding is an alternative source of funding for entrepreneurs to fund their ideas through small or medium-sized capital contribution from a larger amount of investors, often investors who have any kind of relationship with the entrepreneur or to the very idea. This study examined the factors that motivate and guide an investor's decisions when they select their projects. The results of the study show that the motives of the various existing forms of crowdfunding is big.

Kunskapshus eller offentligt vardagsrum? En undersökning av Lunds stadsbiblioteks ombyggnad

In this study my aim has been to discover what connections can be made between the way of creating a library building and the general values concerning the library activities and the library users. What kind of ideology could possibly be reflected in a library room? My study includes two different parts. First of all there is a theoretical section based upon literature relevant for the subject. Here I try to focus on the libraryÕs role in society as a public room.

Att fylla tidningarna med kris : En studie av kriskommunikation, nyhetsmedier och deras källor

The purpose of this study is to discover and explain the influences of media coverage of organizational crises on crisis communication, and vice versa. The study also shows how mediated crises develop, and how media framing and news sources affect this development.Carried out as a case study of three Swedish mediated crises, the methods used are quantitative and qualitative content analysis of media content from four Swedish newspapers and four organizations' press releases from the studied crises.Mediated crises develop through their specific pattern regardless of, but not independent from, the organizations' crisis communication. The crisis communication is used as an elite source in media reporting from the crises, but it can not control the mediated crises. However, it influences framing, and the possibilities to influence media reporting are better in the pre-crisis phase and the culmination..

Utveckling av takra?cken fo?r sla?pvagnar

This report is a bachelor thesis work in the field of product development and design. The assignment has been to develop a solution for roof racks, normally used for cars, to fit on the open trailer models FS1425 and Alugance. The project was implemented by Johan Andersson and Victor Karlsson, students at the Mechanical Engineering program with a focus on product development and design at Jo?nko?ping?s school of Engineering, in spring 2012.The client wants to use transport solutions in the same way as roof racks on cars. The user of such a product is assumed to desire simplicity, safety and an attractive design with an appealing price, which has been a challenge during the thesis work.Pre-studies have been conducted to examine the potential competitors and gain knowledge in the research area.

Another two interviews were made with two informants, this material was included in the background material. As theoretical framework I have used literature about the school library development, the role of the principal for development and David V.

Avståndsmätning med Hög Noggrannhet till Låg Kostnad

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

Påverkad strukturerad produktion produktiviteten? : Analys av mätningar från byggbranschen

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

MEASUREMENT OF C-REACTIVE PROTEIN IN CANINE SERUM ON KONELABAUTOANALYZER 20

An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Att genomföra projekt - Två teoretiska perspektiv på ett problemfyllt projekt i ett kunskapsföretag

This thesis examines a project that has been conducted at a software development company. The aim is to investigate which problems firms of this kind faces performing projects. We choose a theoretical frame consisting of a modern view on how to manage projects. The view argues that the management of each project has to be adapted to the situation at hand. This theory is divided into two separate streams of reasoning; one emphasize learning, delegation of responsibility and flexibility, while the other argues for control, time planning and the importance of keeping to the plans.When we compare the theories to the case we draw three main conclusions: A thorough phase of investigation is required to produce the necessary planning documents.

"Det är svårt att få dem att stanna längre än tre år" : måste rekryteringsprocessen förändras för att tillfredsställa unga medarbetares krav?

How does a corporation work during the recruitment phase to entice and motivate younger members to work for their organization?The aim is to examine in which grade corporations and organizations? recruitment needs to adapt to encounter Generation Y on the labour market.The base in our method is abduction and our research is based on a qualitative method. We have fulfilled interviews with corporations such as Scania, Skatteverket, Swedbank and Appelqvist & Ottoson HR AB.Corporations need in a sense change their recruitment and emphasis their resources to sell the whole corporation and its image to the young job applicant. The younger members demand a total impression of the corporation to implement an interest and to get motivated to work there. Together with our respondents we have realized that Generation Y has higher demands on their workplace than earlier generations..

Skarven : ? Produktutveckling av en oljedimavskiljare

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

Nu vågar jag vara chef: utvärdering av Norrbottens läns landstings chefsutbildning ur ett NPM-perspektiv

The public sector has through the years been exposed to a rather radical alteration. The aim with this alteration has been to make the public sector more effective. It?s a dynamic society that Norrbottens läns landsting (NLL) operates in today and it is therefore of great importance that the managers get a solid foundation to rely on, since they have a central role in the ambition for efficiency. Another reason to educating the managers is that NLL can secure the future pension losses.
