Moder Jord i kyrkorummet? : En undersökning av kopplingarna mellan det kristna och det fornnordiska i Vester Egede kyrkans dopfunt som objekt och vad angår motivval, tolkning och dopritual.
A church in rural Vester Egede from the earliest Christian period in Denmark e.g. the early 1100, a baptismal font is found showing a woman breastfeeding two animals. She is said to be a typical early roman Luxuria, in mild appearance. However, what makes her unique is that she appears standing on the top of her head, her womb serving as font. The main question is how come that a baptismal font like this is to be found in a church, leading to the sub question, if this font really has a Christian origin or could it be rooted in Norse, pre-Christian tradition, alternatively is the font an expression of a syncretism between the two colliding cultures.
INOMHUSMILJÖ I SMÅHUSMED FTX-VENTILATION : EN LITTERATURSTUDIE MED ENKÄTUNDERSÖKNINGAR OCHMÄTNINGAR
This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.
Perenner i Norrbotten - Ja, varför inte? :
In this thesis, I have discussed which (herbacious) perennials that are sold most in
the county of Norrbotten in the upper north of Sweden. Also discussed are the factors
considering overwintering and factors that affect the chances of survival. The reason
to the subject is that I m born and raised in Norrbotten and throughout the years I ve
wondered why so many of the perennial flowerbeds look so similar. The purpose of
the thesis is to give another approach to the composition of the garden by explaining
some of the factors that controls the survival of plants. The information is gathered
partly through interviews with plantshop personnel and partly by a literature study.
The results of the interviews reveal that tradition and hardiness is the major reasons
to the consumer s choice.
Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen
Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The
dynamics and paths of losses of phosphorus from arable lands are not fully understood.
It is known that phosphorus can be lost directly from plant material to water.
In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted
under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials.
In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.
Opportunities for improved environmental sustainability of a wine producer in South Africa : natural resource management and climate change adaptation and mitigation
South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.
Avvikelser i energiprestanda
Calculated and measured energy in residential buildings is going to differ. The reason to this may be due to many factors. In this study there is a study on how these factors affect the energy use in a building. To get an insight in what defines energy, there is first a description of energy supply both worldwide and used in Sweden, followed by a description of the energy balance. In this study energy will be studied in residential buildings only.
Provtagning av trädkärnor för att bedöma föroreningsgraden av klorerade lösningsmedel i grundvatten
Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.
Energikartläggning av polishuset i Gävle : Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10
The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
En Survey av NFC och NFC-Protokoll med Fokus på Säkerhetsaspekterna
Near Field Communication (NFC) is a short range wireless communication technology that enables data exchange between devices. NFC is used in many different areas, from subway tickets to authentication systems. This paper presents possible security threats to Near Field Communication and documented attacks that have been used to target various NFC protocols. Weaknesses in different NFC protocols will be presented and suggestions on how to counter certain weaknesses will be discussed. This survey will be valuable for companies interested in protecting their data when using or planning to use NFC systems..
Enegiutredning Hotell Princess
This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.
Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp
The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.
Ett land som inget annat : Bilden av Sydafrika före, under och efter en utbytestermin i Stellenbosch
The mental constructions of other places are based on impressions from everything that surrounds us in our everyday life, e.g. pictures, videos, texts and narratives. The tourism industry is especially influential when it comes to creating the image of before ?unknown places?. Furthermore, it has a tendency to embellish and idealize people and places located in what is commonly known as the Third World.
