Background: Due to outsourcing, the material flows in the telecom equipment industry have undergone major changes, which in turn has imposed new challenges for packaging supplier Nefab who delivers to the industry. In order to achieve market intelligence, Nefab wants to map the material flows, and investigate possibilities of further reusable logistical packaging systems.Purpose: The purpose of this thesis is to describe the typical features of the logistical material flows in a technically based, rapidly growing industry, and analyze the driving forces and obstacles, which influence the selection of logistical packaging system. Procedure: After developing a theoretical framework consisting of general logistical theories and theories related to logistical packaging, we have interviewed companies in the logistics channel of Ericsson Radio Systems.Results: We have found the main characteristics of material flows in our investigated industry to be Variations in Demand, Focus on Time-to-Customer, and Globalization of Logistics Channels. Regarding driving forces and obstacles in the selection of logistical packaging systems, we have identified Transportation Characteristics, Customer Demands, Quality, Handling & Administration, and Current Packaging System as important factors..

Purpose: To explore the purchasing function, mainly the supplier selection activities, in the fast fashion apparel industry. The purpose is 1) to explore the criteria associated with supplier selection for fashion products, and 2) to analyze the purchasing activities in order to find characteristics and trends which are considered to be strategic for the buying company. Method: The empirics consist of qualitative interviews with employees with responsibility for the companies' purchasing activities, as well as information gathered from articles, annual reports, and company websites. Result: The study indicates that qualitative criterias have increased in importance, and have become an important part of supplier selection for fashion goods. A number of characteristics where identified as important for purchasing fashion goods, which can affect choice of supplier; examples are increased collaboration, increased re-buys and increased use of logistics services.

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

This graduate thesis deals with the challenges facing us as we gradually make our urban environments withtheir many public buildings, such as shops, cafés and cinemas, more accessible for disabled people. Theperspective taken is that of the conservationist, who in her or his profession looks to the cultural andhistorical characteristics in buildings and building environments. In order to gain better accessibility, changesin the physical fabric need to be made, with consideration for the cultural and historical characteristics.The introduction presents the subject of considarate accessibility. The second chapter deals with the legalaspects concerning the protection of buildings as well as the accessibility for disabled people. Severalinterviews with different participants are presented here, aiming to tie the legislation to the reality of theconservationist, the disabled, the civil servant working with accessibility issues and the property owner,whose responsibility it is to make the adjustments necessary to improve accessibility.

Sycamore maple (Acer pseudoplatanus L.) is a common broadleaved species throughout Europe, however often of minor interest to the forest sector. There is currently a lack of research on sycamore maple, and some of its characteristics have throughout history contributed to a negative reputation in both literature and the forest society. Since broadleaved species in general are of great importance to the forest sector in Europe and presumably of enhanced significance in the future, deepened research is needed and particularly Swedish. With a desire to hopefully increase the interest for sycamore maple, was the objective of the study to examine the current status of the sycamore stands in southern Sweden. The study was carried out both as a survey with inventory field work and as a literature study. Parts of the latter mentioned is also presented in the introduction. The study shows that the majority of the sycamore stands in Sweden are growing well, producing fairly high qualities and volumes.

Background One of the main demands on Swedish and global health care in general is to meet the patient?s need for safety. By general health care law this also comprises district nurses? field of responsibility. Although there are numerous studies describing the concept of safety and its different shapes, no research could be found exploring how safety is, or supposed to be, mediated by district nurses? in a Swedish context.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

Syftet med detta examensarbete var att ta fram en modell för att attrahera innovationsmöjligheter till Munktell Science Park i Eskilstuna. Detta gjorde författarna genom att från befintliga teorier deducera fram en hypotetisk modell. Modellen används inte för att skapa innovationer utan för att hitta komplexa problem. Det är lösningarna på de komplexa problemen som i sin tur kan vara innovationerna. Därför har vi kallat de komplexa problemen för innovationsmöjligheter. .

In recent years, customer profitability has become a focal point of academic discussions on business performance. However, researchers remain divided as to how evaluation of customers ought to be conducted, resulting in uncertainty of how accounting systems should be adapted to prevailing conditions. This paper aims to investigate the application of customer accounting techniques and the role they play in the organisational and commercial context in which they take place. In a case study of Billerud, a Swedish company providing materials and services for packaging solutions, the interplay between customer accounting techniques and customer relationship characteristics has been examined through the application of a theoretical framework developed by Lind and Strömsten. Particular emphasis has been put on deviations from the prescribed pattern of the framework.

For many individuals gambling gives an opportunity for relaxation and social relations. The positive effects of gambling are for most individual?s considerable more than the negative effects. Even if gambling gives positive effects there is individuals that cannot control there gambling and therefore develop an addiction which disturb there life situation and health. The aim of this study was to describe which personal characteristics distinguish people with a pathological gambling and which psychological, physical and social consequences this pathological gambling causes for the individual.

The work examines geographical variations of bicycle use in Trondheim municipality with the aim to create an understanding of what influences the use of bicycles and explain the geographical travel pattern for cycling. The work focuses on the how physical structures generates different transports effects. Where bicycle travels in Trondheim municipality are undertaken is described by using network analysis in ArcGIS, based on aggregated data from the travel habit survey (RVU) in 2009/2010. Trondheim municipality is divided into smaller geographical units (zoner) whose characteristics are described by 19 variables, categorized into 6 groups; Distance, Land use, Topography, Bicycle Facilities, Road characteristics and Demographic factors.By linear regression analysis in SPSS and ArcGIS Spatial Analyst, an explanatory model is elaborated. The variablesdistance to the regional center, workplace density, percentage separate bike paths and hilly terrain explains 78 percent of where cycle journeys are undertaken.

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.
