The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

This is a study about the communication interaction in the context of the reference work at some public university-libraries and some private company libraries in Gothenburg and Borås. The primary purpose of the study is to investigate the communication interaction in a library situation. The second purpose is to deepen the knowledge, understanding and to establish what is important in this communication. Focus has been on how the intermediaries communicate and how she or he perceives this communication. The intermediary needs to manage the communication with all the different patrons and different information needs of the patrons.

Marknaden för flygmotorunderhåll har blivit allt mer konkurrensutsatt sedan nya aktörer börjat ta marknadsandelar. Det kärvare marknadsklimatet har främst drabbat de små fristående underhållsleverantörerna. En av dessa små fristående underhållsleverantörer är Volvo Aero Corporation, VAC, i Trollhättan. Ett problem vid flygmotorunderhåll är behovet av reservmotorer. Kapitalkostnaden för inköp av reservmotorer är mycket hög, samtidigt som bristkostnaderna också är mycket höga.

The number of firms adapting the concept of Corporate Social Responsibility is constantly growing. It is no longer enough only to supply your customers with demanded products and services since todays? customers have an increased awareness and are demanding more transparence when it comes to the manufacturing and responsibility for society.Along with a growing interest in social, ethical and environmental matters, many firms have received critique, consequently forcing them to start taking more responsibility for their activities. The clothing industry was among the first to get critized and therefore early in starting their work with CSR.The purpose of this paper is to investigate how firms in the clothing industry work with CSR today, and also how they choose to communicate this work, both internally and externally. The methodology of the paper is qualitative and aims to deeply investigate four different firms, along with an additional interview with a CSR-consult from one of the leading communication-firms in Sweden.The theoretical foundation includes a frame of reference around CSR and the communication thereof, and also a few relevant theories around CSR and business ethics.After analyzing the empirical material the paper have reached a few conclusions.

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.

Syftet med denna studie är att se vad som påverkar förbättringsmöjligheterna i en försörjningskedja. Detta har vi gjort genom att analysera ett terminal- och logistikbolag i Kiruna. Efter att ha gjort lite efterforsking kom vi fram till ett forskningsproblem (FP) och två forsknings frågor (FF).? FP: Vad påverkar förbättringsmöjligheter i en försörjningskedja?? FF 1: Hur påverkas befintliga och potentiella kunders önskemål om logistiklösningar i en försörjningskedja med hänsyn till miljöpåverkande effekter?? FF 2: Hur ser utvecklingsmöjligheterna ut för en försörjningskedja i en kontext under stark omvandling?Studien påvisar att det finns ett antal faktorer som påverkar förbättringsmöjligheterna i en försörjningskedja. De viktigaste faktorerna som vi kom fram till är pris, samordning och miljöpåverkan..

The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

The purpose of this thesis is to give an understanding of how grocery stores relate to local foods. Through a case study representatives for two groceries in Norrbotten have been interviewed regarding why they supply local foods, how they try to influence customers to buy this, and how they decide upon the assortment of local foods. The result shows that groceries supply local foods in order to supply a wide range of products and to mediate social responsibility, in order to create customer loyalty. Concerning how the groceries try to influence customers to buy local foods the result cannot give any clear-cut view. Instead it shows that a grocery that actively works to influence customers to buy local foods markets them in specific ways, while the opposite applies to a grocery that does not actively work for this.

Background: A large number of companies works as a link between manufacturers and final users. These companies buys and stores goods to be able to deliver when a need comes up later in the chain. The storage could have a negative effect on profitability and therefore places great demands on the management control systems. ABC as a method has been used with some success in manufacturing for over ten years. In wholesale companies the method is not frequently used.
