Torkat bioavfall som jordförbättringsmedel
The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.

Hemlösa ungdomar - ett osynligt problem : En kvalitativ studie om avsaknaden av en enhetlig problembeskrivning
Homeless adolescents are in Sweden rather invisible, as a group. There is no established definition or description of the problem, nor any uniform terms regarding it. The purpose of this study is to investigate how four different organizations, based on their basic principles, describe the group homeless adolescents. We discuss why the organizations reason as they do, and what it leads to. In order to do so we have performed qualitative interviews with representatives from each organization.
Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge
Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.
Att beskriva upplevelsen av stadens rum :
The city is complex, multi-faceted and fascinating. The same can be said about the rooms
of the city. The experience of the rooms of the city can be described in as many ways as
there are individuals. The question concerned in this essay is How can you describe the
rooms of the city as a phenomenon and how can you describe the experience of these rooms
in general?
The concepts city and room are widely understood and neither of them has a description
that can be used in all situations.
Kartering av markföroreningar inom Skutskärs Bruk samt utvärdering av spridningsrisker enligt Naturvårdsverkets MIFO fas 2
With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.
Hygienisering av torkat bioavfall
The main project Dry preservation of food waste from households includes a new technique concerning drying and storage of dried biowaste as well as a study of the sorting of household waste and further usage of the dried biowaste. A question asked in the project is, can the dried biowaste be used as a soil amendment? If organic waste is used as a soil amendment, precaution concerning hygienic safety risks has to be accounted for. The objective of this M. Sc.
Side effects of biological control agents in agriculture : does the bacteria Bacillus amyloliquefaciens affect the earthworm Aporrectodea longa?
Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.
Ådalen 1931 - Göteborg 2001: en jämförelse av två händelser som skakade Sverige
Ådalen 1931 - Göteborg 2001, A comparison of two incidetns that upsett Sweden. An essay about how the press in Norrbotten wrote about the incidents in Ådalen 1931 and Göteborg 2001. The main questions are: Is there any parrallells in how the swedish state acted? Is there any parrallells in how the press acted? In what way have the state and the press acted different 2001 compared to 1931? What does eventual differences in their actions depend on? The so called biträdesteorin is used to answer theese questions. The essay includes three big newspapers in Norrbotten: Norrbottens Kuriren, Norrländska socialdemokraten and Norrskensflamman.
Reducerad jordbearbetning : en fallstudie
This is a study made because I would like to see how much money can be saved when
reduced soil preparations is used. This is a case study, the farm is located in the north
vest part of Skåne, Sweden.
I have calculated with four different soilpreparation methods.
Alternative 1: Conventional soil preparation, the way the farm is managed today.
Alternative 2: Ploughing on depth of 12 centimeters, with a ridge packer followed with
sowing.
Alternative 3: Eco-tillage
Alternative 4: Direct drilling
The results of my study showes that Alternative 2 is the most profitable. Alternative 4 is
very good if you see to dieselexpenses and hours of work, but the yield is far to low.
If the numbers are further analized, it showes that in spring barley the differense
between Alternative 2 and Alternative 4 is at a minimum. So if there is lack of time for
one reason or another, this might be an alternative in spring barley.
The differense in how the farm is managed today and the most profitable alternative in
the study, Alternative 2 showes that it can be saved up to 60 940 SEK..

Teachers today face the task of meet those children in the best way. Södertörn University has a special profile on their teacher education, the intercultural profile.Aims: My report focuses on teachers who have been working in preschools for about one to two years after graduating from the intercultural education at Södertörn University. The report aims at finding out more about their experiences and thoughts about the intercultural approach after having worked in the Swedish preschool with a special focus on the intersectional perspective on cultural phenomena class, gender and ethnicity.
Markvattenhalt och temperatur i sandig jordbruksmark vid Ilstorp, centrala Skåne : en mätnings- och modelleringsstudie
Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Europa och som man i slutändan hoppas ska kunna resultera i en vinderosionsmodell. Detta har genomförts med SOIL modellen, en matematiskt fysikaliskt baserad modell för simulering av vatten och värmeflöde i en skiktad jordmånsprofil..
Demand and perception of fertilizer : among small-holder farmers in Kenya
Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.

Outsourcing av urval och inköp : En studie av hur bibliotekariens kompetens och yrkesroll påverkas av Bibliotekstjänsts profiltjänster
Traditionally, the majority of Swedish public libraries have carried out most of their acquisitions through Bibliotekstjänst's binding booklets. In recent years, however, many libraries have complemented the binding booklets and other services from Bibliotekstjänst by other ways of acquiring books, such as Internet bookshops, while other libraries have stopped using the binding booklets altogether. There are various reasons for this development, such as Information Technology making it possible for librarians to compare prizes and services from different retailers. Another important reason is the need for public libraries to meet new needs from their patrons, while remaining on a restrained budget, which often causes a need for reorganization of staff and resources.As a way of meeting the new needs for libraries, Bibliotekstjänst has created Profile Services (profiltjänster), a service in which a library outsources its acquisitions to Bibliotekstjänst. The staff of the library, in dialogue with Bibliotekstjänst, design a profile for the acquisitions for the library in question, in order to determinate which types and genres of literature the library and its patrons are requesting.
