Effects of ten year old enrichment plantings in a secondary dipterocarp rainforest : a case study of stem and species distribution in Sabah, Malaysia
Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).

Studie av skyddsavstånd mellan bergvärmeanläggning och skyddsobjekt i ett vattenskyddsområde
During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

Underlag för solcellsproducerad el i Stockholm : Potential och klimatpåverkan
The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.
Naturvärden i en värmländsk bruksskog : en skogshistorisk studie av Åbengtshöjden/Bogranghöjden
In this study I have analysed the history of a forest belonging to Saxåhyttan in Värmland. The study area is 448 hectares and has been used by iron industry since the 16th century. A forest that has been used by man during at least 400 years should have few ecological values. This inventory however shows the opposite.
The aim of the study is to interpret the history of the forest in the area, i. e.

Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering
Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.
Förhandsbedömningar : Förklaringar och konstruktioner
AbstractIn Östhammar a change has been noticed in the statistics regarding incoming reports, appraisals and investigations concerning a suspicion that a child or youth may be harmed.There are some earlier reaserch made concerning the sorting process that takes place when a report is made. In Östhammar the social workers have been interested in finding out what the main reasons are for not opening an investigation. It has also been some research from the ?sociology of childhood perspective? on how childhood is being constructed and how children are positioned in the investigative texts. From a social constructionist perspective and by using both a quantitative and a qualitative research, I have examined all the reports that have not led to an investigation from the first quarter of 2011 in Östhammar. This to find out the main explanations for not investigating and how children are positioned in such appraisals.It has been shown that most appraisals closed either because of the situation which led to the declaration no longer exists, to another input already exists, the problem is not seen as serious or that it was felt that the parents are capable of giving the support they need. I have discovered that the childs voice is missing in most of the report investigations. I have not found any explanations to why one has chosen not to speak with the child, but there may be explanations such as limited time, limited knowledge or a will to spare the child the discomfort..
Stenhuggaren på Korpåsberget : vilken bild förmedlas av stenhuggarens liv och arbete på Korpåsberget?
My essay aims to explore, "What image is conveyed by the stone mason's life and work on Korpåsberget". In my essay I have been working with respondent interviews to examine the purpose. I've been trying to get interviewees to talk freely, but have also had a number of indicative questions for support. In order to process and understand the interviews, I also have a part in the essay aiming to provide background information to the stone industry in Bohuslän, an area along the westcoast in Sweden, and foremost in the area of Bovallstrand.The text discusses the stone industry's development in the area, its development and the time until the stone industry at large was closed. As for the stone industry in Bovallstrand I have chosen to focus on the largest quarry in society, namely the Korpåsberget. The background text also briefly covers stonecutter?s lives and work.
