Fuktproblematik i platta på mark : En analys av uppkomsten till fuktproblem
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

This thesis aims to increase understanding and knowledge of issues affecting the redevelopment of older office buildings to housing. The rising demand for housing in recent years has resulted in a need and an increase in cost housing projects. The need has led property owners wanting to build old office buildings to apartments. The case study is carried out in Lycksele town and in close contact with consultancy TM (Technician Mercantile) ? consulting, which has operations in the area.
Staten och civilsamhället i Uruguay
Lack of political interest and will to deal with human rights violations carried out under the civil- military dictatorship, has characterized the transition and post-transition in Uruguay. The systematic use of torture, arbitrary imprisonments and forced disappearances in the relatively small country created a culture of fear that has been present through out the post-transition phase. Human rights groups have been central actors in the fight for truth and justice and against impunity. This study analyzes how these groups multiple democracy-building functions have contributed to democratic development. It also analyses how the democracy-building functions have been constrained by the political context.
Gerillaodling - ett frö till förändring
Abstract A phenomenon that has been noticed more and more in media and the public space in recent years is what is called guerrilla gardening. It means the illicit cultivation of someone else?s land. This report's intention is to analyze what impact guerrilla gardening could have on today's urban space in terms of stable changes in norms and physical design. I have also focused on guerrilla gardener?s choice to carry out these actions illegally, without asking for permission, and what impact that could have on the issue of appropriating public space.
Förutsättningskontroll och nedbrytningstest på oljeförorenad mark : Preem 2, Karlstad
More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).
Ljudisolering - Teknisk felsökning och kvalitetssäkring av lätta bygg-system
By using industrialized building, pre-installed modules can be delivered to the construction site where they are easily mounted. This method has many advantages compared to on-site manufacturing, for example, the precision during the production process should be much higher than building each wall and floor on site. Furthermore, the quick erection procedure when using prefabricated elements and the possibility to use weather protection has the advantage of not being dependent on weather conditions, and many other factors.Masonite Beams AB is a Swedish company (a member of the Norwegian company, Byggma ASA) with a relatively new technology using light weight beams as bearing elements in the walls and a certain stiff board lamella slap which is mounted on the top of the floor structure creating an integrated stiff beam / board floor structure. The elements are flat which make it much easier to transport the elements from the factory to the building site where the building parts are easily mounted with special mounting stud.One of the main drawbacks of lightweight structure is the sound transmission. The main topic is low frequency annoyance, however the complex structural elements and their mutual sensitive connections other acoustical problems might appear.
Hallbyggnadsteknik - en effektivisering av småhusproduktion
Syftet med det här examensarbetet är att undersöka om det är möjligt att överföra hallbyggnadsteknik till produktion av småhus för att sänka produktionskostnaderna. Studien visar att hallbyggnadsteknik enkelt går att överföra till en villa. Dessutom blir det billigare att bygga klimatskalet med vårt byggsystem jämfört med ett traditionellt prefabricerat småhus. Genom detta system kan den totala byggkostnaden för villan i jämförelsen sänkas med 3-10 % beroende på vilket fasadmaterial som väljs..
Förhandling vid tomträttsavgäldsreglering av kommersiella tomträtter - Med fokus på beräkningsmodell för avgäldsunderlag
The objective of a site leasehold is to allow the lessee to occupy a specific plot of land. In return, the lessor imposes an annual ground rent. The ground rent ownership gives the lessor the possibility to capture the increasing in land value. As such, the rent is based on the value of the land multiplied with a percentage that reflects the yield of the land value. It is renegotiated every ten years.
The Podcar Way : hur kan spårtaxi integreras i en urban miljö?
A new system of public transportation that can simplify and shorten the trips made throughout the city, anddo that both cheap and environment-friendly. Sounds like good news. This new system, though, require anall new type of infrastructure, differing from what we are used to see in our cities. Podcar, or PRT, as thesystem is called can become a transport revolution, possibly. If that revolution does happen it is crucial that webeforehand have studied the possible effects it can cause on our city environment, from a spatial point of view.This thesis thoroughly describes the function and essence of the PRT system and presents what is availabletoday and in what forms.
Presence of Japanese Encephalitis virus vectors in Can Tho City
Japanese encephalitis virus (JEV) is a significant vector-borne zoonotic pathogen, causing devastating encephalitis in humans. Its geographical range includes a majority of Asian countries and has also been recognized in some western Pacific areas. The main vectors of JEV are mosquitoes belonging to the genus Culex. Birds and pigs function as hosts and virus amplifiers, whereas humans are accidental hosts. Japanese encephalitis is commonly regarded as a rural disease.
Föränderliga stadsrum : flexibilitet, dynamik & interaktivitet
The number of inhabitants of the towns and city centers have generelly increased, concurrent as the population in smaller towns has decreased. In Stockholm, the migration is very fast and here is also the most populous place, if one compares with other Sweden.
In order to respond to the increasing population and the pressure they put on city spaces has Stockholm's town a town building strategy that says "build inwards". It means that one stem seals the town with spaces and business activities in central locations.
The increased population in the towns and the densification of buildings leads however to an increased pressure on parks and public places.
Kvalitetssäkring vid arbete med fukt i virke
There are many factors in a building project that has to collaborate with one another in order to reach the desired end result, how you work with moisture issues in timber is a very important one. While constructing Varbergs Hospital, the building company Skanska came in contact with the issue of extra high demands on the moisture content in timber. What they requested from us was a moisture program in which you clearly could follow the routines regarding work with moisture in timber. The aim is to use this program as a help during the work, in order to achieve a good result.We have developed this study in addition to the moisture program. The aim is that this study will give you a deeper understanding of the important factors to consider.

Organizing for value creation : a corporate perspective on urban farming
In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.
