Biogas is an expanding sector within the broad field of agriculture and animal production. Small-scale biogas offers local combined power and heating production and the substrate is transformed into high-quality biological fertilizer. This bachelor thesis focuses on a pig farm in south-western Sweden, where biogas is produced from pig manure, evaluates and suggests ways of optimizing the process and investigates whether investing in an upgrading plant would be a feasible and more cost-efficient option. The results show that the biogas plant is working well, although the production differs from the original plans. This shows in turn that planning and examining the basic conditions before making the investment is of great importance, as well as monitoring and keeping detailed statistics of the running process.

The title, ?You simply must own your classroom?, is taken from a quote from one of my informants.After review of earlier research on how teachers handle their leadership in the meeting with disturbing pupils and which strategies they use to solve problems in the classroom, interesting questions developed. What experiences do teachers have of disturbing situations in the classroom? Which strategies do they use to solve the problems? What kind of support do the teachers consider necessary in teaching? Are there any differences in teachers? experiences and strategies between the two selected schools? The study is supported by earlier research that deals with pupils? and teachers? perspective and strategies in different classroom cultures in terms of norm-breaking behaviour of pupils. The study is also supported by three different theoretical perspectives such as power structure, social order/disorder and support strategies.I conducted the study through interviews with sex teachers who work in the same municipality but in two separate schools.

Our purpose in this paper is to examine if there is any profitability for a company with a factory in the timber industry to invest in a combined heat and power, CHP. Based on analysis and the results that the paper generates, we will give Derome AB a suggestion on how it is a profitable investment or not to installing in a CHP.By investing in a CHP plant, you can get a high efficiency, which means that companies can use their resources more effectively. The Swedish wood industry has by-products of production that can be used for combustion in their boiler which is an advantage.The essay is a qualitative study where we have a case company, Derome AB. In this company, we interviewed two employees who have knowledge in the study. They have helped us to provide information and data about their business.We chose to use the pay-off- and the net present value method, NPV, to see if there are profitable advantages for the investment.

The purpose of this essay is to illuminate two teachers? communication strategies when dealing with pupils with another first language than Swedish. One of the teachers teaches Swedish as a second language and the other teacher educates one class in most of the subjects such as mathematic, Swedish and social studies. I make an ethnographic study where I make non-participating observations and shorter interviews with the teachers. The observations lie in focus of my study and were made at eight occasions, four lessons with each teacher.My result shows that they have a lot of communication strategies in common, but not all.

Breast cancer is the most common form of cancer which struck women around the world. When a human is exposed to threat or stress, e.g. breast cancer, different coping strategies are used in order to cope with the situation by the afflicted person. The aim of this literature study was to describe how women, who suffered from breast cancer, experienced coping with their situation. Scientific articles were found in the databases Medline (Pub Med) and Cinahl.

Theories about exposure and risk-taking in an everyday environment show a connection between parental strategies, parent-child relationship and exposure on the Internet. In the present study, the Internet is presented as an everyday activity. Negative exposure is seen as an outcome of risk-taking. The purpose of the study was to examine in what way parental strategies together with the parent-child relationship were related to the teenagers? negative experiences on the Internet, which consisted of three categories: 1) Exposure to pornographic sites, 2) Exposure to upsetting and violent material, 3) Digital bullying.

Background: According to the Swedish Social Board induced abortions are increasing in the modern day society. Nurses who work with in the gynecological department can come across patients seeking care for an induced abortion.Theoretical framework: The findings of the study will be discussed in relation to Peplau's nursing theory, ethical concepts and nursing concepts.Aim: The aim of the literature review was to illuminate the experiences of nurses working with induced abortion.Method: A systematic literature review with an inductive approach was chosen. The findings are based on seven qualitative and two quantitative studies. The articles were assessed through two different modified templates based on qualitative or quantitative design.Findings: Nurses and midwives experienced their work with induced abortions as emotionally stressful. However, it was highlighted that all women have the right whether to choose abortion or to proceed with the pregnancy.

This study?s aim is to investigate how multilingual students learn mathematics and teaching strategies used to support the students? development of knowledge. A total of eleven scientific articles were selected for analysis and comparison. The results showed that visual representation, multimodal forms of expression and the students? whole linguistic repertoire constitute central resources for learning.

New Zealand is currently the third largest global producer of kiwifruit and thus plays an important role in the international market. Exports of kiwifruit are also of significant horticultural value for New Zealand and in 2007 the kiwifruit industry accounted for export values of NZ$790 million. The global kiwifruit market has experienced substantial changes in recent years and is likely to change significantly in the near future due to developments in production sources, adjustments to trade policy settings and shifts in consumer preferences. The New Zealand kiwifruit industry needs to consider what the impacts of these changes might be so that future strategies can be constructed effectively. Little quantitative modelling has been done in New Zealand to consider the impacts of changes to the global kiwifruit industry. The major contribution of this research was the development and calibration of a kiwifruit industry-specific partial equilibrium trade model. The model was then used to examine the impacts on New Zealand producers of these trade-related changes in the global kiwifruit market.

This paper is a literature review that examines how good mental calculation skills benefit pupils, which could work as a valuable learning tool for future teachers. The study addresses four key questions: ?What are the advantages of proficient mental calculations??, ?What strategies exist for mental calculation skills??, ?How can teachers accommodate their teaching to develop pupils? mental calculation skills?? and ?What has arithmetic looked like in different eras and what algorithms have been used??. Through literature searches in search engines, scientific articles were found, which formed the basis for the result segment. This was divided into two parts: A historical and a didactic overview.

Background Swedish nurses are required by law to document nursing care. Studies have proved scarce in nursing documentation with regard to written language, the nursing process and the nurse´s caring perspective.

This thesis explores how the city of Gothenburg integrates and use social capital, defined through factors such as trust and cooperative networks, in its crisis preparedness strategies and how this can enhance the city's collective resilience. The study aims to contribute to the understanding of how social capital can be leveraged to strengthen crisis management and resilience in urban environments. The research analyzes existing quantitative data from the SOM-Institute regarding residents perceptions and self-reported preparedness actions and reviews Gothenburg's official civil defense plan for 2024?2027. By examining various aspects of social capital, including levels of trust and cooperative networks across different city districts and age groups, the analysis focuses on how social bonds and community contexts are considered in planning for handling and recovering from potential crises.

Through the information strategies I examined the selected groups? information environments.

AbstractThe aim of the research presented in this thesis is to study how interactional strategies are used by children and what these strategies mean or imply in the preschool cultural context. The theoretical point of departure in the study is the socio-cultural perspective (William Corsaro, Roger Säljö, Jim Wertsch). The study is a contribution to the field of research that focuses upon contextual issues and an overall way of seeing the child. This is in opposition to the strong traditional psychological perspective in the development of the child, where a focus upon the individual dominates in special education. This ethnographic study aims to answer the following research questions; What interactional strategies are co-constructed by the children in preschool play? How do the interactional strategies influence the creation of culture in preschool play? The children, 3-5 years olds, and their play situation were in focus.
