Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer
Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which Leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor
In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.
Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
Kundens bidrag i innovationsprocessen : En studie om användande av kunder för att upptäcka latenta behov
Title: The customer?s contribution to the innovation-process ? a study of using customers to discover latent needs. Level: Final assignment for Bachelor Degree in Business Administration Author: Robert Klein Supervisor: Agneta Sundström Date: 2014-06 Aim: The purpose of this study is to gain enhanced understanding of what knowledge costumers contribute with in an innovation-process Lead by a producer of goods, and how that knowledge is used to fulfill latent needs. The area of research has formerly described which results customer-involvement Lead to, but have been scarce in describing how results are produced. Method: From a qualitative onset, a case-study collecting data through observations and interviews capturing customer knowledge contributions, and producer use of fetched knowledge has been conducted. Data has been analyzed using a grounded theory approach. Results have been processed in several steps in which material has been categorized and enriched continuously. Result & Conclusions: Customer-knowledge is broken down into market-knowledge, everyday-knowledge, and specialist-knowledge, which all are significant to a producer of goods.

Ostalgie : DDR-nostalgi i det återförenade Tyskland
This essay is a case-study of a phenomenon called ?ostalgie? which could be described as GDR-nostalgia. ?Ostalgie? is a compound of the two German words ?ost? (east) and ?Nostalgie? (nostalgia.) It is, like a similar phenomenon referred to as ?communist nostalgia?, a type of nostalgia. However, if one were to define ?ostalgie? as ?communist nostalgia? important aspects of the phenomenon would be left out.
Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca
The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the Lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.
Hästen ? en medgörlig kompanjon eller en överexploaterad resurs?
The horse was domesticated about 6000 years ago. Since then humans have used the horse for different purposes, such as work force and in sports. Horses are social, group living animals that spend around 16-17 hours a day on grazing. Horses are often kept stabled in single boxes with a limited feeding time. The forage usually contains grain-based concentrates and roughage.
Privatiseringen av de växtgenetiska allmänningarna : Konsekvenserna av regimkomplexet kring växtgenetiska resurser för bönders rättigheter och matsäkerhet
This thesis discusses the global regime complex concerning the management of plant genetic resources for food and agriculture, and how different regimes concerning these resources cooperate or stand in opposition to each other. Because of changes in US patent law and the establishment of TRIPS, patent claims over plant genetic resources has increased dramatically globally. This, amongst other things, in turn has Lead to the development of CBD which in turn Lead to the creation of access and benefit laws in many countries. To create a free flow of genetic resources for food and agriculture the ITPGRFA, with its multilateral system, were negotiated. The aim of this thesis is to investigate which consequences the regime complex concerning plant genetic resources for food and agriculture can have on the rights of small farmers, agricultural research and food security in the global South.
Inkludering - Utopi eller verklighet?
The aim of this paper is to shed some light on to what extent the process of making reality of Inclusion, as stated in International Declarations and in Government policies, has reached the actual educational activities in the school system. My chosen method is a case study, in which I have combined a survey with interviews in order to retrieve enough data for my analysis. I have also studied a number of policy documents and relevant literature. My analysis concludes, for the school that I have chosen to study, that there is still a lot to be done before inclusion becomes a reality. There are many obstacles to overcome, for instance; a constant struggle to obtain enough resources and to reach relevant levels of competence within the personnel.
Klimatanpassning med grönstrukturplanering : Med exempel från Malmö stad
Climate change is expected to Lead to increased rainfall and higher temperatures, among other things. This will have a major impact on our cities. Floods can Lead to property damage as well as damages to human and animal health. Higher temperatures will increase the frequency of heat-related health risks and premature deaths. The consequences of climate change will be particularly large in our cities because of the city's morphology with a high amount of paved surfaces and buildings that affect the natural processes in areas such as drainage and absorption of solar radiation.
Styrsystemets roll i balanseringen mellan kontroll och empowerment : En kartläggning av ett styrsystem och varför användningen leder till observerade effekter på personalen
Problem discussion: That empowerment and autonomy can Lead to desirable effects on employees is clear. Previous research has found correlations between empowerment and e.g. motivation, job satisfaction, productivity, loyalty and commitment. However, a control problem arises when employees have more freedom in decision-making which could potentially Lead to undesirable outcomes. It thus becomes a type of dilemma for management and managers where you have to try to balance a restrictive use of the control system (to maintain control) and an enabling use (to promote empowerment).Purpose: The purpose of this study is therefore to identify how a company can use its control system in order to achieve empowerment while maintaining acceptable levels of control.

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.
En ny diskussion kring religionsfriheten : Alternativ till religionsfrihetsbegreppet under Europakonventionen och Europeiska domstolen för de mänskliga rättigheterna
Freedom of religion or belief is indisputable in Human rights discourse, more discussed is exactly what it is that is included in the concept of freedom of religion or belief (in Swedish: religionsfrihet). This thesis focuses on the freedom of religion or belief in a European context, in particular on the European court of human rights and article 9 in the European convention for human rights. Some criticism has been directed against the Court to the effect that its practice and verdicts don't answer to the pronounced desire to develop a pluralistic and inclusive form of freedom of religion or belief.My aim is to examine, analyse and test three different theories, which all try to develop alternatives to the expression freedom of religion or belief, in relation to six verdicts from article 9 in Europe convention. My basic purpose is to try to find new ways of talking about freedom of religion or belief that might Lead to a more inclusive, pluralistic and equal interpretation of that concept.The three theories wich I use are elaborated by Richard Amesbury (associate professor at Claremont school of Theology); Hugo Strandberg (TD at Åbo Akademi) and Eberhard Herrmann (professor in philosophy of religion at Uppsala University); and Martha Nussbaum (professor of law and ethics at the University of Chicago). The six cases from the European court are: X v.
