Fordonsgas ur gödsel och vall

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

Detection of mutations in dihydropteroate synthase (dhps) and dihydrofolate reductase (dhfr) in Plasmodium falciparum in eastern Sudan

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

Minimizing acts of violence through telephone-linked care: an
automated telephone system for outpatients in forensic
psychiatric care

Achievements within the fields of computer- and telecommunication technology have led to a revolution when it comes to managing information. These achievements have made it possible to offer new services in healthcare, especially in telemedicine. New technology has become a complement to traditional care, thus partly compensating for insufficient time and resources. Telephone Linked Care (TLC) is a telecommunication technology that enables automated dialog counselling and monitoring of patients in their homes. During the last two decades numerous randomized controlled studies with TLC have demonstrated improvement among outpatients with chronic and health behaviour disorders.

Militära ?mobil-appar? : Den militära nyttan med kommersiell teknik för militära ändamål

The transformation of the Swedish Armed Forces is bringing about major changes in many areas. Indirect fire is one capability affected by these changes. Financial savings, a shrinking organization and higher eligibility requirements mean that fewer soldiers will gain access to exclusive high-tech support resources such as the JAS 39 Gripen aircraft and the ARCHER artillery system. This thesis aims to examine whether access to indirect fire capability can be increased through the use of civilian products and communication networks. Technology development in the civilian mobile communications area is exponential and nations such as the USA, facing challenges similar to those of the Swedish Armed Forces, devote substantial resources to research and development.

AbstractThis study deals with NTA in preschool and the purpose of the study is to find out how the NTA project works out in practice. In the empirical study I have used questionnaires as a research method (Trost2001). Questionnaires have been sent to preschool teachers in the whole of Sweden to get as good a selection as possible. The responses received have been processed and analyzed. The results are reported below.The majority of the teachers thought it worked well to work with the NTA.

Kunskapshantering inom växande IT-bolag. En kvalitativ fallstudie på ett mindre IT-bolag

This paper intends to examine the knowledge challenges in small IT companies which is going through rapid growth. The movement of information and knowledge is a social and very complex process. The challenge for technology is the social as information and knowledge requires. To believe blindly that technology will solve the problem is what many people think. In order to understand how technology can support information and knowledge management one needs to understand what information and knowledge is.

Vad är god fysikundervisning? : Studie av några lärarstudenters uppfattning med Repertory Grid Technique

I studien har en relativt ovanlig intervjumetod, Repertory Grid Technology använts för att ge några blivande fysiklärares syn på god fysikundervisning. Metoden inspirerar till användning i många andra sammanhang. Resultaten visar att god fysikundervisning bland annat uppfattas som krävande för läraren..

Användarupplevelse av ett komplext infotainmentsystem i en bil. En verklighetsbaserad studie av gränssnittet mellan människa och fordon

In recent decades here has been a huge development in information technology (IT), where we humans are increasingly using IT in our daily lives, ranging from social media to music streaming services; this has also been a reflection of the technologies developed to our cars. Infotainment systems have become an increasingly regular feature in modern cars where the high degree of integration such as navigation, mobile and Internet has become more common and more sought after. Despite this, relatively little research problemized User Experience of a complex infotainment system in a car. This study thus has the intention to consider the relevance of reality based tests by examining how the user experiences a complex infotainment system in a car. We asked ourselves; How do the user experience a complex infotainment system in a car? We conducted our qualitative study, an interview with researchers in the field of vehicle and road safety and designed a number of system-related activities in a test session where we observed three users.

Taggade bibliotek ? en studie av adoptionen av RFID på svenska folkbibliotek

The purpose of our research was to examine whether the acceptance and diffusion of RFID technology among the employees at public libraries in Sweden, follow the classic diffusion of innovation model. RFID or Radio Frequency Identification, is a technology that uses radio frequency and microchip technology to track items, in our case, library books and other library materials. Diffusion is the process by which, in our case, the RFID technology is adopted by the library staff. The purpose of this study was to examine what factors influenced the acceptance and adoption of RFID among the library staff. We used Everett Rogers' Diffusion of innovation theory as our framework.

Utmattning av vägbroar i armerad betong enligt eurokoder

Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.

IKT som pedagogiskt verktyg : - en studie om lärares användning av IKT i undervisningen

 The purpose of this study is to investigate the attitude to and experience of information and communication technology (ICT) in teachers teaching and what motivates them. The study is qualitative and its research material is based on interviews. There are eight interviews and they where carried out at one school with a stated IT profile and at another school without a stated IT profile. The two schools are located in different municipalities, but both are secondary schools. The result shows that there are differences in attitude between the two schools. The school with a stated IT profile seems to have a more open mind of using ICT when teaching, but both schools sees the lack of availability as one of the main hindrance for using it. None of the participating teachers saw themselves as controlled to use ICT in their teaching.

Interna processer : Modell för ett effektivt returstålsflöde

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

CAMPUS BTH : ett gestaltningsförslag och en studie av begreppet campus

This text answers the questions how do we define what a campus is, how the concept of the campus came to exist and how it is used today, and how the Blekinge Institute of Technology (BTH) campus can be designed according to site conditions and the conclusions drawn from case studies at Chalmers University of Technology and Karlstad University. The purpose of the case studies is to gain insight into their campuses advantages and disadvantages. This finally results in an interpretation of how the Blekinge Institute of Technology campus can be planned. A campus is the area of land on which a college or university and its surrounding buildings resides on. Campus as a concept meant a field at first, it later evolved at American universities due to their design of college campuses.
