Brandsläckning och textil restvärdesräddning Hur saneras textil efter en pulversläckning?
This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.
Utvecklingsalternativ för grisbesättning :
The purpose of this report was to compare two different options for expanding of an
existing pig farm. For the time being there are low prices within the agricultural market
of pig production, and it is interesting to see if it is worth expanding or not.
The two different options this report is based on are: expanding from a herd with 50
sows in breeding gilt production to a herd with 100 sows in breeding gilt production
(option 1), or expanding to a herd with 140 sows in breeding gilt production (option 2).
The number of pregnant gilts produced per year will stay the same for both alternatives;
about 300 pregnant gilts per year. The rest of the breeding gilts will be sold at a weight
of 25 kg. The pigs that are not sold as breeding gilts (e.g. castrates, and female pigs that
are too small or that have disorders) will be kept on the farm as growing-finishing pigs
until 120 kg of live weight, and then sold to the slaughter house.
By using the existing buildings, even after the expanding, the investment costs, and
thereby costs for housing, were kept as low as possible.
Hur skapar man en funktionell och beständig dörrmiljö? : En närmare studie av ståldörrar
Today?s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex.In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed.Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made.
Energieffektivisering av Badmintonstadion AB i Umeå
Badmintonstadion i Umeå vill söka bidrag hos Umeå kommun för att genomföra energieffektiviserande åtgärder. Stadion är byggd år 1990-1991 och har 13 badmintonbanor fördelat över tre hallar, ett gym, omklädningsrum och en mottagning för sjukgymnastik. Umeå Energi försörjer lokalen med el och fjärrvärme. Syftet med detta arbete har varit att undersöka vilka energieffektiviserande åtgärder som är mest ekonomiskt lönsamma. Lokalen förbrukade under år 2013 234 MWh el och 134 MWh fjärrvärme (graddagskorrigerad).
Förslag till bebyggelse och park i kvarteret Seminariet i Uppsala
In the urban planning debate of today, two strategies for city development stand out as each other's opposites, urban sprawl and smart growth. This thesis concerns a development project of the latter kind and aims to give an alternative proposal to new buildings and a park in a Swedish city block. The term sprawl is used for new developments on virgin soil on the outskirts of cities leading to a city spreading, while smart growth stand for increased city density through development on re-used land within the city boundaries. The latter are often seen as more sustainable in many levels and are also shown to have positive effects on a number of city functions. At the same time smart growth has negative consequences on other aspects of the city such as public open spaces.
MILJÖCERTIFIERINGSSYSTEMET MILJÖBYGGNAD I PRODUKTIONEN : En fördjupning inom området ?Material?
The environmental assessment system Miljöbyggnad is a Swedish system initiated by Bygga-Bo-Dialogen to assess buildings with regards to three main areas; ?Energy?, ?Indoor climate? and ?Materials?. A building can obtain three different classifications depending on how well it manages to meet the demands. GOLD is the highest classification and is followed by SILVER and BRONZE. The majority of the measures needed to comply with the demands are done during the design phase.
Life Cycle Cost : Studie om LCC som verktyg att utva?rdera geoenergianla?ggningar
Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods.
Energi och klimatanalys O-huset på Campus i Halmstad
AbstractThe indoor environment affects the human performance. Noise pollution, poor lightning and coloring are some of the factors that affect our work performance. The human is also affected by the air change and temperature, these factors are in most buildings possible to adjust and through this make economic savings. To find out about the indoor environment in the O-building a questionnaire was handed out, measurements/surveys and an interview was also made. 108 questionnaires where handed out to employees and students.
Vad är viktigast i staden? : Utveckling av ett lokaliseringsverktyg för stadsplanering
This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.
"Jens Holgerß af Glimynge" Om en borgbyggares intentioner
Glimmingehus is one of the most well preserved medieval castles in Sweden. This essay examines why it was built ? what were the intentions of the Lord, Jens Holgersen? Even though we?ll never be able to ask him, the answer to the question ?why?? can give us aninsight of how a man of his position thought in the Late Medieval time. To answer the question the castle are explored through three different angles ? the Lord of the castle and thesocial context the castle was built in, the landscape surrounding Glimmingehus ? has Jens Holgersen left any structural clues there, and finally the castle itself ? how has a potential visitor experienced Glimmingehus? The methods are greatly influenced by Gunhild Eriksdotter, who in her book Bakom fasaderna explores the possibilities of an analysis ofexperience together with an analysis of function in the archaeology of buildings.
Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system
BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.
Fårens anpassning till värme och kyla
Får finns i stora delar av världen och i helt olika miljöer. För att klara av att leva väl under så vitt skilda levnadsförhållanden har flera hundra olika raser utvecklats, vilka skiljer sig bland annat vad beträffar ull, storlek o fettdeponering. I Sverige ökar produktionen av lamm året runt, vilket innebär att lamning sker även under de kallaste vintermånaderna. Detta skulle kunna innebära problem då lammen kan ha svårt att hålla sin kroppstemperatur vilket påverkar överlevnaden. Insatser som kan göras för att förbättra lammens chanser är att utfodra tackan väl, klippa tackan några veckor före lamningen, se till att tackan slickar sitt lamm torrt och försäkra sig om att lammet har god tillgång på mjölk.
Organisationskultur i fusion : en studie av neurologiska kliniken på Karolinska Universitetssjukhuset
Mergers and Acquisitions have become more and more in common knower days among the companies. Factors that might influence could be such as power of competition or it could even be the aim of new strategies of the company. In mergers is it not only the buildings and the physical objects that is put together, also the human beings within the organization are put together. Each person contributes to the culture, which makes the situation more complicated. In making a merger successful, it is important to pay attention to the organizational culture.
En studie av höghusbyggande med avseende på stomsystem och lastpåverkan
Vi har valt att undersöka vilka möjligheter och eventuella risker det finns att bygga högt i Stockholm. Undersökningen utgick på att jämföra olika byggtekniska lösningar för stomsystem. Hur tar stomsystemen hand om vertikala och horisontella laster? Vilket stomsystemen är lämpligast vid en viss höjd? Dessa är några av de frågor som besvaras i arbetet.De vertikala och horisontella lasterna är de faktorer som främst försvårar höghusbyggandet. Med en större belastning av laster ju högre det byggs måste stomsystemen dimensioneras med allt större noggrannhet för att lasterna ska nedföras till grundläggningen på ett säkert sätt.
Eldens arkitektur : En studie av de medeltida varmluftsugnarna och deras betydelse
AbstractThis thesis examines and discusses a sample of the medieval hypocausts (stone-heating ovens) in the Baltic area. The medieval construction is thoroughly explained as well as the antique hypocaust in order to establish a base for the following discussion. The medieval hypocaust has been almost forgotten for a long period of time. The last time someone dealt with this category of finds were in the 1960?s by Swedish archaeologist Iwar Andersson and in the 1970?s by Danish archaeologist Johannes Hertz.
