Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

Miljövärdeflödesanalys av Risifruttiproduktionen : En utvärdering av värdeflödesanalys och miljövärdeflödesanalys

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

Kollektivtrafik längs Litteraturgatan. En jämförelse mellan olika kollektivtrafiksystem med avseende på kapacitet.

There are many elderly buildings, particularly those constructed during the million program, in need of renovations and plumbing replacement. An alternative to the traditional plumbing replacement is the relatively new and untested technique called relining. The purpose of the study is to thoroughly investigate the different types of relining that are currently available on the market to help enhance Peab?s knowledge before purchasing relining services. The theoretical part of this report is based on relevant information provided from companies, previous studies, investigations and reports within the area.

Oberoende skivbolag i förändringstider : Om den förändrade affärslogiken i skivbolagsbranschen

During the last decade the conditions for the music industry have been changed significantly. With the dropping sales of physical phonograms and the increasing illegal file sharing, the record labels have been forced to adapt and thus seek alternative sources of income next to the traditional sales of phonograms. Our purpose was to investigate how smaller Swedish record labels adapt themselves to the changing environment within the music industry and which new alternative sources of income they can use to finance their music production. To do this we used a deductive approach where we started by researching theories we thought were relevant to the subject, which we then used to get valuable information out of our informants.From our empirical investigations it appears that the independent record labels are rather positive about the future and that they will be able to survive, even though they will have to change their ways of working to a large extent. Our results show that the record labels as we know then will disappear.

"En ryggradslös lag" : Om LSS-besvär hos länsrätten rörande personkrets tre

AbstractThe purpose of this study were to examine the appeal that reaches the county administrative court regarding cases within The law of support and service to some disabled (LSS) the third "alternative" with the effort personal assistant. We have gathered 280 cases from seven different county administrative court and from our selection 19 of the cases remained.These 19 cases became our starting point for our study and they have been interpreted through Foucault´s and Skau´s interpretation frame regarding power and Payne´s social constructivism to try and answer our three questions at issue: How are the cases being handled by the county administrative court? What kind of cases leads to appeal? What similarity and differences are there between the cases? These questions have been answered one by one in a systematical order. Our result shows, among other things, that cases that involve certificates from occupational therapist or physiotherapist are the cases that win against the municipality in the county administrative court. Further we have found a new theme in our study regarding clientification among them who apply for efforts within LSS and "alternative" three.

Alternativa hylluppställningar: en användarundersökning på fyra folkbibliotek

The aim of this master?s thesis is to examine how users at four public libraries experience the alternative shelf arrangement in their library. The purpose of introducing an alternative shelf arrangement in a public library is often to facilitate for its users. In each of our chosen libraries, the librarians have arranged the books in the non-fiction section in broad themes, with the Swedish Library Association Classification System as subsections. Using qualitative interviews, we examined a total of 26 users? experience of the shelf arrangement and its accessibility, their methods for seeking information and their opinion about the presentation of the books.

Hylluppställning i förändring ? En studie över svenska folkbiblioteks alternativa hylluppställningar

The aim of this thesis is to study how public libraries in Sweden use alternative shelf arrangements that differ from the library?s original classification system, which in Swedish public libraries usually is the SAB-system. I sent out a survey to 169 public libraries, where I received 114 replies. 77 of these stated that they had some kind of alternative shelf arrangement, therefore these are the ones that are included in my study. I wanted to investigate in what way the libraries had changed their shelf arrangement and why this decision was made.

Den som vinner barnen, honom tillhör framtiden - Valfrid Palmgren och Stockholms barn- och ungdomsbibliotek 1911-1927

In 1911 Valfrid Palmgren founded the Children's Library of Stockholm, the very first in Sweden.She was a well-educated woman, who believed in social and educational equality for all.During a journey to the USA in 1907, she was deeply impressed by the public libraries, andshe put many of the public library ideas to use in the Children's Library of Stockholm. Palmgrenstrongly opposed to the Swedish libraries not allowing admission to children, since shefirmly believed that educating the people had to start with the children.Other reasons for opening a children's library were to give children an alternative to roamingthe streets, to give children a quiet place to read, to give an alternative to the cheap trashliterature that flooded the market and to teach the young ones how to extract information frombooks. Of great importance was that the library should be equal to all classes in society.In 1927 the children's library was taken over by the new public library of Stockholm..

FPGA baserad PWM-styrning av BLDC-motorer

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Ett aktivt beslut att renovera passivt : En ekonomisk jämförelse vid upprustning av miljonprogrammetsflerbostadshus

As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

Är Sambandet Mellan Utdelningsandel och Framtida Vinsttillväxt Positivt

Common wisdom dictates that because payment of dividends decreases funds available for investment, a high payout ratio is to be associated with low earnings growth. This notion has been challenged in recent years by empirical research that has found a positive relationship between payout ratio and future earnings growth, both on the aggregated market level and the company level in different countries. This study investigated the aforementioned relationship on the Swedish market by statistically analyzing future earnings growth as a function of payout ratio on a large sample of publicly listed companies over the period 1980 to 2011. The results are in line with those found in previous research and indicate that companies with high dividend payout ratio tend to experience strong future earnings growth. The results are robust to the presence of mean reversion, the use of an alternative accounting measure of earnings, non-symmetrical earnings growth cycles and alternative practices for dealing with outliers..

Sverigestallet eller uppbundet :

When I got the opportunity to write this examination did I want to write about something that I both was interest in and also can use in the future. I think it?s going to be difficult to carry on the milk production with only 28 cows. I wanted to investigate the possibility to increase the herd of cows. I also wanted to compare this cost with a new cow house the cows where milked with a robot.

Vindkraft och elbilar på Öland år 2020 : Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?

The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.

Klöver i ensilage till suggor - effekter på reproduktion och produktivitet

The weather has been extremely rainy the last summers in Sweden. Because of the rain, a lot of harvested straw has been lost since it was too wet to store. When the pig producers couldn?t get enough straw to use as bedding, an alternative was requested. Silage is a realistic alternative to straw but since silage often contains clover, it may not be suitable to use in pig production since clover is rich in phytoestrogens.

Vårlamm eller dikoproduktion i Dalarna : fallstudie

This study investigates a farm in Dalarna which includes 16 ha of farmland and 1, 7 ha of pasture. The purpose is to find out if it is possible to start an animal production in Dalarna. The study is set only to compare spring lamb production with nurse cow production. There are two buildings on the farm that can be used for this purpose. One is an old cowshed, and the other is an unused silo for silage with a roof on top. Both of the buildings are compared to every alternative in the calculations.
