Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

Nötköttsproduktion i Västerbotten

Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.

Motorikens betydelse för inlärning

AbstractMy purpose with this study is to find out if it helps children who have diffuculties with their concentration if they get to practise their motor behaviour knowledge during their day at the school to promote their learning capacity. My purpose is also to find out how schools works with motor behaviour training. To get answers to my questions have I done interviews with four educationalists and I have also used books and internet sites. Motor behaviour is of importance to how children learn things in the school, without a well working motor children gets difficulties to sit still and to concentrate. The children may put their energy at the wrong things in the classroom, when the energy instead should be need to learning things.

Därtill är jag nödd och tvungen : En fokusgruppsstudie om distriktssköterskans erfarenhet av läkemedelsdelegering i hemsjukvård

AbstractBackground. The need for drugs delegation is increasing as more and more sick people are cared for at home and too few nurses working in home health care. Because of this, the number of delegations per nurse is often unacceptably high.Aim. The aim of this study was to describe the public health nurses´ experience in drugs delegation to home care staff in home care.Method. In this study a qualitative method with an inductive approach was used.

Passivhus ? lönsamhet och komfort

In this essay, we have compared a conventional house to a passive house. The housesshared the same local conditions; they have the same living area and the same layout. Thedifferences between the houses were the different construction solutions for the roof, theouter walls, the floor and the heating system. Both the houses qualify the standards fromBBR and the passive house also lives up to FEBY?s special conditions.The purpose with the essay was to examine if it really is profitable to build small hoses aspassive houses.

Myndighetssamverkan i Barnahus : Blir det bättre för barnen?

Many children are being abused by daily basis. Mostely they are abused by a parent or another person that is close to the child. Mostely the child abuse never is reported to the social services or to the police, and even if the perpertrator is known, only a few cases are brought to prosecution. If a case allthough is drawn before the court of law, there are still too many of the perpetrators that are being acquitted. In other words, the legal security for the abused children is way too low.When suspiscions arise that a child is exposed to child abuse there are several inquiries that starts at the same time.

Föräldramedverkan vid utförande av vårdåtgärder i hemmet efter instruktion/utbildning från sjuksköterska : Föräldrars och sjuksköterskors upplevelser

Introduction: Parental involvement is becoming increasingly common in the paediatric health care. Parental participation at home means that parents receive instruction by nursing staff in order to perform a caregiving procedure at home.Aim: To explore parents' feelings about performing caregiving procedures on their child at home, and their experience of instruction about these, and to explore nurses? experiences of their instruction to parents.Method: A descriptive quantitative and qualitative design using questionnaires with statements to be responded by nurses and parents according to scales graded 1-10. The study was carried out during the autumn of 2009 at a pediatric unit in the University Hospital in Uppsala.Results: Ten completed questionnaires from the nursing staff and ten from parents were obtained. The mean assessment of parents' perceived safety and security, and their perception that their questions had been answered ranged between 8,6 and 9,2.

Småskalig elproduktion i Arvika

Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

Utvärdering av en väggkonstruktion utan PE-folie : Med en undersökning av hårdvaxolja som diffusions-/konvektionsspärr

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

According to Nosti (2012) banks target youths to find new customers by giving them special offers such as debit cards from a relatively early age. However, Moschis and Churchill (1979) point out that age can affect the level of knowledge in the consumer. Therefore, this essay focuses on youths as consumers. Specifically, youths? awareness of security risks in using bank tools such as debit cards or internet banks was studied.

Äldres berättelser om åldrandet

ABSTRACT Our main objective with this essay is to provide a description of old people?s stories about aging. The essay is based on the empirical source of four qualitative interviews with older people over the age of eighty years young. The main goal is to inquire answers about; their time in the workforce; retirements; healthissues; media/advertisements; adolescence/youthfulness and attitudes. The following main questions have been dealt with: What do the elderly emphasize when they describe ageing? Are healthissues the prime subjects the elderly talk about? Do the elderly experience positive or negative attitudes towards ageing? What is their point of view of younger generations? In what way do they describe their years as workers? In what way do they describe aspects about their retirement? We reserved to consider the opinion of their own, to be the most valuable source in our study.

Bring Your Own Device : Ur ett säkerhetsperspektiv

Syftet med denna studie är att identifiera hot, risker och konsekvenser kopplade till BYOD samt undersöka hur dessa kan lösas. BYOD är idag något som införs i allt större utsträckning hos olika företag världen över. Många är intresserade av alla möjligheter det kan frambringa, dock blundar allt för många för alla de olika hot och risker det samtidigt kan medföra. Utöver det tar vi i denna studie även upp hur man kan skriva en säkerhetspolicy kopplad till området BYOD. För att komma fram till våra slutsatser har vi förutom den teori vi samlat in fått hjälp av Jan-Olof Andersson en av Sveriges främsta IT-säkerhetsexperter med att skapa en riskanalys och en arkitekturbild.

Resolution 1325 was adopted by the members of the United Nations Security Council in year 2000 and aims to increase the efforts made to secure women's rights and security in parts of the world where war and crisis prevail.

Farmers preferred end-values related to their use of forward contract : a means-end chain analysis

Today?s farmers are constantly affected by the fluctuating world market prices on grain and thereby the price risk that comes with the price fluctuations. The volatile prices of grain increase the price risk within the business, which in turn affects the profitability of the business. The fluctuating prices together with the increased price risk within the farm business have opened up the market for hedging instruments. In this master thesis project, the aim is to identify the underlying end-values of 30 Swedish farmers? related to their choice of using hedging and the product; forward contract.
