Effektivare hantering av foderspannmål : en fallstudie

The purpose with this work was to investigate some alternatives for an effective handling with grain, to find the most economic alternative. It is not common that moisture content is below 14% when harvesting grain in Sweden. To store the grain safe it has to be preserved in some way. I have described some of the most common systems for preserving grain in this paper. I have used the systems as a basis when I made calculations in handling the grain for a company. I have chosen a company placed in south of Sweden. The productions are crop farming and pork.

Peltierelement - spillvärme till el : Peltier element - waste heat into electricity

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

Hur ser diskussionerna ut kring det nya Kregelverket?

The aim of the study was to look at a particular work group of housing supporters, whomhave implemented two special working methods in their work. The methods have been implemented by two of the housing supporters that also have special education in the methodsSOC (Sense of Coherence) and solution focused brief therapy. The study is based on anethnographic observation and analysis of documents that are used in the implementation. To analyse the information that was given at the observation and in the document I´ve used a theory which illustrates the significance of developing professions so their knowledge become legitimate. I´ve also used a theory that illustrates the importance of implementation and how it´s done at its best.

Limmade träförband

Utvecklingen av förbandsmetoder är viktigt för att utveckla konstruktionslösningar. Under det senaste decenniet har forskning på limmade förband utförts, främst på inlimning av stålstag och plattstål i limträ. Förhoppningen är att spänningen ska fördelas jämnare i förbandet och att brott ska kunna undvikas. Hypotetiskt sett skulle det kunna göra knutpunker utan synliga förband möjliga vilket även skulle gynna arkitekternas önskemål.Genom en sammanställning av tidigare forskning dras en jämförelse mellan testresultaten och en antagen knutpunkt som belastas av egentyngder och variabla laster. På så sätt kan limmets kapacitet konkretiseras.

En tand för en tand och en våtmark för en våtmark - ett återskapande värt pengarna? : En undersökning av nyttan och kostnaderna av att restaurera våtmark med hjälp av Contingent Valuation Method.

The goal of this study is to examine what five teacher?s impression of the teacher?s role is in their previous years. How important the ?joy at work? is in relation with the educational progress? And what aspects that contributes to the? joy at work? and what obstacles that stops them. The essay will also go through the concepts of a teacher role, with connection to the theoretical perspectives of Csikszentmihalyi?s Flow and Antonovsky?s Salutogenesis (KASAM).The method I used was interviewing five teachers and I used Larsen?s chapter of ?content analysis? as a basis, I also used Flow and KASAM as theoretical references in my analysis.

Att synliggöra de osynliga : En analys om fyra kvinnliga irreguljära immigranter och om hur deras relationer till andra människor påverkar deras livssituation och identitet

The objective of this paper is to describe and analyze female irregular immigrants and their experience of how relationships with other people affect their lives and identity.A qualitative method is used in the study, because my main purpose is to analyse the respondents? lives and life experiences. The analysis is based on a symbolic interactionism perspective. The results are also analyzed based on previous research and the concepts underlying the paper; irregular immigrants, discrimination, power and identity.In summary, the respondents have a clear picture of how they live and experience their relationship to others and themselves and how this affects their lives and identity.Their experiences affect their lives and influence their behaviour and identity when they interact with others. Their own view of their situation means that they are afraid to seek care or report sexual abuse, threats or other similar conditions.

Lämpliga främmande trädslag för Kalmar och Mönsterås kommuner

This report concerns the for Sweden foreign tree species hybrid larch, hybrid aspen and poplar, and focuses on the area Kalmar and Mönsterås municipalities. The report shows that there are not only advantages with these species. The larch, the most common of the alien tree species has the greatest problems due to that its timber is difficult to sell in the area but also the Larch´s poor pulp quality and is more likely to be damaged by wildlife than the spruce is. Hybrid Aspen is much easier to sell and is used like regular aspen for match wood and textile pulp. Its disadvantage is the high cost for plants and to prevent damage from wildlife.

Fluid Simulation for Visual Effects

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..

Framtidens Teater finns inte. En beskrivning av ett icke-linjärt projektarbete

This is a non-traditional examination paper written after three years of studies at Malmö University and the Kaospilot Program. It is written in Swedish and in the spring of 2009. It describes a non-linear project based on a process-orientated theory called Theory-U by Otto C. Scharmer (2009). The project aims to investigate the changing conditions of Stage Theatre and deals with non-linearity as phenomena.

Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Inverkan av röjning och gödsling på mikrofibrillvinkeln i tallens (Pinus sylvestris L.) ungdomsved

Tall (Pinus sylvestris L.) är ett av Sveriges viktigaste trädslag. Med ökad efterfrågan på vedråvara samt ökade krav på naturavsättningar är det viktigt att öka produktionen i skogen. Röjning och tidig gödsling ger ökad volymproduktion men kan ge icke önskvärd påverkan på vedegenskaper som ökad mikrofibrillvinkel (MFV). MFV är vinkeln mellan mikrofibrillerna i cellväggens S2-lager och cellens längdaxel och påverkas av ståndort samt konkurrensen om ljus och näringsämnen. Höga MFV resulterar i sämre kvalitet på papper och sågade trävaror.

Ytbehandling baserad på hampolja

The varieties of paint are today very big, but many of the more popular paints are less than environmental friendly. The uses of fossilized fuel in paints are common because these paints dry fast and are color true. It would be beneficial for the environment if more renewable source were used to produce paint. Linseed oil is an old base for oil paints. It is renewable and easily procured.

Automatisk detektering av akustiska resonansfrekvenser i trästockar

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Perspektiv på kompetensutveckling i praktiken: en intervjustudie av HR-arbete i ett globalt företag.

During the last decade working with competence has emerged as a more strategically important area. Today the human resources in a company are considered a competitive advance and the HR-units play a significant role when it comes to HR-management. Different motives for investing in strategies that promote competence development and learning also exist. The purpose of this paper was to examine how the process of competence development was managed at a large global company. The empirical material consisted of four persons who were interviewed and the analysis of the material was inspired by grounded theory.From the analysis four major themes or core factors emerged as central to the interviewed persons' understanding of the competence development process; solid preparatory work in relation to competence development, communication, awareness of responsibilities and finally the taking action and evaluation of the action.
