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..
Gynna nyttodjuren i hemträdgården
Biologisk bekämpning innebär reglering av oönskade växt- och djurpopulationer med hjälp av
naturliga fiender. Det finns fyra grenar inom biologisk bekämpning och en av dessa är gynnande av
naturliga fiender. Det innebär att förutsättningarna i trädgården anpassas så att önskvärda invånare
gynnas och på så sätt minska populationen av skadedjur. En viktig skillnad mellan gynnande av
naturliga fiender och de andra formerna av biologisk bekämpning är att inga organismer sätts ut
utan de naturligt förekommande används.
Det finns många olika nyttodjur som bör eftersträvas att ha i trädgården. Dessa brukar delas
in i predatorer, som jagar och äter upp bytesdjuret, och parasitoider, som parasiterar genom att lägga
sina ägg i eller i närheten av sitt byte.
Genom att skapa en mångfald av olika sorters växter i sin trädgård kan en mängd olika
insekter och andra djur lockas dit.
Movement patterns of Eurasian lynx (Lynx lynx) around their kills in southern Sweden
During the last ten- fifteen years the Eurasian lynx (Lynx lynx) population in southern Sweden has increased considerably. This area has a high density of both people and roads and have a higher roe deer (main prey of lynx) density than the rest of the country. Movement patterns such as how long animals utilize their kills and how far they travel from their kills between revisits is unknown for lynx in southern Sweden. The aim of this study was to examine how different factors affected the time lynx used their kills and the distances they travelled from the kill between revisits. The data was prepared and calculated using ArcGIS and the study is based on 98 ungulate kills and 12 lynx individuals.
Beteenden hos geparder i två stora svenska djurparker
Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.
Verkställighetsföreskrifter, uppdragsarkeologi och konservatorer - Konservatorns integrering inom uppdragsarkeologin
To increase the quality and the cost-efficiency of contract archaeology in Sweden a revisedregulation for contract archaeology was established the 1st of January 2008. By including findstrategy as a concept with special demands in the regulation the Swedish Heritage Board is nowhoping that the conservators will be integrated earlier in the archaeological process and that theunpremeditated find accumulations will stop. This is making the competition between thearchaeological companies even harder. The questions are how the regulation have affected therole of the conservators in the field of contract archaeology today, what is affecting theintegration and the situation, and what can the different stakeholders do to make the collaborationbetween archaeologists and conservators more professional? The conservators are now hopingthat this is the change that will increase the collaboration with the archaeologists, which isimportant for the finds prosperity and the drive of information.To get an updated and generalised view of the impact of the regulation so far, phoneconversations and questionnaires were carried out with archaeologists, conservators, employees atcounty administrative boards and the Swedish Heritage Board.

Rydboholms engelska park : historik och vårdprogram
The estate of Rydboholm is situated in the municipality of Österåker, north of Stockholm, Sweden, and has a long history dating back to the 14th century. Rydboholm was the home of several families of great national importance, such as the Finsta and Vasa clans. However, since the 1500s, the noble family Brahe was the most influential; leaving its mark on the castle and surroundings. The gardens of Rydboholm consist of two parts; The first is from the baroque era, dating back to the 1660s, and the second is an immense landscape park completed around the year 1800 by Magnus Fredrik Brahe.
During his travels through Europe, Magnus Fredrik Brahe was influenced by the new English-style gardens and he brought a large collection of literature on the subject back to Sweden, still kept in the library of Rydboholm.
En kartl?ggning av inv?ndiga f?nsterluckors utbredning och konstruktion
Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in
modern buildings. In modern contemporary construction, large glass panels are often the ideal because
of increased light inflow and for architectural purposes. However, this can generate several negative
effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that
window shutters could have accommodated historically.
This thesis identifies a lack of knowledge about interior window shutters in the Swedish building
stock.
Energieffektivisering av befintlig bebyggelse med exempel från Göteborgsområdet
This thesis concerns to investigate renovations of existing buildings aiming at enabling energy efficiency, from a conservation and restoration perspective. This includes performing case studies of three projects in the Gothenburg area where renovations has been done and an analysis of directives raised by the EU and later implemented by the Swedish National Board of Housing, Building and Planning, Boverket. In addition to these, regulations enforced by the Swedish law, related to the topic, have been considered.The investigated projects in this case were the housing cooperative Välten in Brämaregården, the Solar Buildings in Järnbrott and Gårdsten as well as Katjas Gata 119 at Backa Röd. In order to measure and compare the results of these projects a comparison between the pre- and post-restoration energy consumption have been performed. To capture additional perspectives the grading system Operation Kungsörn has been applied.Regarding the comparison of energy consumption the renovation of Katjas Gata 119 was found preferable but showed in my view lacking attention to the cultural heritage of the area.

Grodsamhällen längs vattendrag på Borneo : En identifiering av habitatkaraktärer viktiga för diversitet och abundans av grodor i tropisk regnskog
The stretch from the riparian zone of a major river, through the mouth and upstream in tributaries forms a range of differing habitats. The aim of this study was to investigate the effect of these different habitats on the riparian frog community in primary rain forest in Borneo; i.e. examine whether any gradients could be demonstrated in terms of species composition, diversity and density of frogs, as well as which environmental characteristics that seem to be of most importance in forming habitats of high conservational value. A major river, Segama, and three of its tributaries were investigated. The surveys were carried out at night by searching for frogs visually and acoustically along the streams, from the shore of the Segama river and 400 metres upstream in the tributaries.
Kulturarv för evigheten? Studie av kyrkans utveckling och framtid med exemplet Skallsjö kyrka
The aim of this study is to describe and analyze the history and the current situation of the Church of Sweden. The renovation of Skalljö church in Lerum municipality has been used as an example to enlighten the common changes in the church buildings. The long history of the Church of Sweden as the state church has resulted in the fact that it carries a remarkable part of the Swedish cultural heritage. The reason why the Heritage Conservation Act (1988:950) was altered in January 2000 was due to the change of relations between the State and the Church of Sweden. According to the Act, all church sites owned or managed by the Church of Sweden shall be maintained in such a way that their cultural historic value is not diminished and their appearance and character are not violated.Sweden is today considered to be a secularised country where religion is an individuals? private matter.
Hur kan naturvärden och rekreativa intressen tas tillvara vid byggnationsprojekt? : Fallstudie Tyresö strand
Under det senaste årtiondet har 97 % av den totala folkökningen tillkommit inom fem kilometer från kusten, främst kring storstadsregionerna. Tyresö kommun är en av Stockholms förorter. Kommunen har under åren köpt loss tomter i ett kustnära område vid Tyresö strand. Ekologigruppen ab har på uppdrag av kommunen gjort bedömningar av områdets naturvärden såväl som rekreativa värden. Bedömningarna är tänkta att kunna vila som beslutsunderlag för planering såväl som byggnationer i området.
Aktör - Struktur : Förslag till utgångspunkt för studier av samverkansprocesser i förvaltningsområden med naturresurser
The focus on this essay is derived from an international and national dialogue for sustainable development. The recommendation from international level has been to find solutions for governments to implement strategies for sustainable development between local and regional level. This initiative is to improve and stimulate the dialogue between the local inhabitants, officials, entrepreneurs and stakeholders in the communities together with the authorities on the regional level. The purpose is to share knowledge and find ways to learn about the natural systems and how to co-operate in the work of preserving the natural resources and developing different processes for a sustainable development. Many scientists? today stress the importance that ecosystem resilience is promoted by biodiversity conservation and that we need to find solutions for local ecosystem management practices.This essay aims to find theoretical approaches and perspectives that can be used in a wider framework to study co-operative processes between the local (agent) and regional (structure) level.
Effekter av upphörd hävd i Lurö skärgård : Har diversiteten av kärlväxtarter förändrats?
En av de största orsakerna till den massiva förlusten av växtarter, är fragmenteringen av habitat. I Europa är öppna naturbetesmarker och ängar de habitat som genomgått de största förändringarna i och med jordbrukslandskapets omstruktureringar under 1900-talet. I den här studien inventerades kärlväxter på 5 olika öar i kulturlandskapet Lurö skärgårds naturreservat. Syftet var att ta reda på hur diversiteten bland kärlväxtarter skiljer sig mellan hävdade gräsmarker och f.d. gräsmarker där hävd upphört och hur ett förändrat landskap spelat roll för artantalets utveckling eller tillbakagång.
