Hörneborg - borg eller lada? : kolanalys, magnetisk susceptibilitet, sjösänkning och historiska kartor.
Hörneborg ligger på en udde i sjön Hörnsjön i Olofströms kommun i Blekinge län. En utgrävning av borgen gjordes 1997 för att fastställa funktion och ålder. 14C dateringar visade att borgen var byggd cirka 1030-1250 e.Kr. och förstördes genom brand någon gång mellan 1290 och 1420 e. Kr.
Tätning eller ventilering mot fukt på kalla vindsutrymmen
This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.
Hur bör unga hundar av storvuxna raser utfodras?
The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein.
The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.
Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder
This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).
Är kolrika jordar en källa till fosforläckage? : en sammanställning av data från 130 åkerjordar
Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore,
the minerals used to produce the mineral phosphate is a non renewable resource.
There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils.
The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).
Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab
ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.
Det självförsörjande passivhuset
The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.
Renbruksplan ? från tanke till verklighet
Renbruksplan (RBP) är ett kommunikations- och planeringsverktyg skapat för Sveriges samebyar. År 1999 genomfördes en förstudie och idag, 15 år senare, har 50 av Sveriges 51 samebyar påbörjat arbetet med renbruksplaner. Idag används RBP av renskötare för att planera sin dagliga verksamhet och som ett stöd i diskussioner med olika typer av markanvändare för att kommunicera och visa rennäringens verksamhet.
Vägen fram till dagens Renbruksplan startade redan under 1700-talet i och med gränsdragningen mellan Norge och Sverige. Renskötseln begränsades till Sverige och sommarbetet i Norge gick förlorat. Efterföljande århundraden fortsätter renskötselsamhället möta förändringar som påverkar dess form och utförande.
Sustainable phosphorus management of horse paddocks at Julmyra
Horse keeping is gaining an increasing interest in Sweden. During 2004 to 2010 the number of horses increased
with 10 - 20 %, and was estimated to be 362 700 in 2010. Julmyra Horse Center (JHC), situated in Heby municipality,
is a gated community for people sharing a large interest for horses and a vision of a sustainable horse
management has been formulated. This study evaluates how the horse keeping of today at JHC, and how an
expansion of the horse keeping may affect the risk of enhanced phosphorus load to the nearby lake system

Utvärdering av den bärande tegel- och betongstommen i en byggnad från år 1916
This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.
Effektivisering av reservdelsförsörjningsprocessen: En studie av Boliden Minerals värdeflöde i reservdelsförsörjningsprocessen
I en värld med ökande globalisering utsätts företagen för mer och mer konkurrens. Vilket medför att företagen ställs inför högre krav på effektivitet och produktivitet för att skapa och bibehålla sin konkurrenskraft. För att upprätthålla effektivitet och produktivitet krävs emellertid underhållsarbete för att stödja de processer som ska möta kundens behov. Detta underhållsarbete medför därför ett behov av att anskaffa reservdelar, en process som bör bedrivas effektivt för att undvika produktionsstopp.Studien har genomförts på Boliden Minerals AB i Kristineberg, vars reservdelsförsörjningsprocess inte upplevts som optimal. Detta medförde att studien ämnat till att studera den nuvarande reservdelsförsörjningsprocessen, att effektivisera reservdelsförsörjningsprocessen och att utreda vilka utmaningar som kan uppstå vid en förändring av denna samt hur dessa ska kunna hanteras för ett effektivt förändringsarbete.
Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Möjligheterna för Casabona-systemet
Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.
Utredning av pallsprängning med lutande borrhål i Aitik
Examensarbetet har utförts vid Boliden Mineral AB dagbrott i Aitik under perioden 2011-03-28 till 2011-06-01. Syftet med examensarbetet var att göra en utvärdering av pallsprängning lutande borrhål för att se om fragmenteringen förbättrades. Dessutom studera andra effekter som påverkas av fragmentering, t.ex. antal icke hanterbara block (stenar större än 1m3), flöde i primär krossanläggning och grävbarhet. Studien genomfördes genom att en försökssalva sprängdes, där en del av borrhålen var vertikala och den andra delen bestod av lutande borrhål.
Renovering av Säteriet, Råda - Från miljonprogram till attraktivt bostadsområde
The homes that were built in the 60?s - and 70's are now so dilapidated and worn that they need thorough renovations. These renovations are expensive to implement for the landlords, which means that the funding for these renovations can create problems. Currently there are no government subsidies for these renovations. This report will examine how Förbo performed the renovation of Säteriet.
