Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.

This essay aims to examine what subject positions are possible within the discourse of relationship anarchy. Through semi-structured interviews with four people who define themselves as relationship anarchists I've made a discourse analysis to determine how these relationship anarchists explain what, in the discourse they?re in, is described as an relationship anarchistic way of being, what isn?t and how they relate to this. Relationship anarchy is described as an ideology based on freedom. It is about the right to define their relationships as they like, as something constantly changing and that does not hold a specific value based on its label.

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

In today's society it has become increasingly important for organizations to take into account non-financial values. Sustainability reporting involves reporting the economic, social and environmental aspects of an organization's operations. The trend has been towards an all the more scrutinizing society with an increasing demand for transparency and translucency. A greater focus on environmental issues has also contributed to sustainability?s increasing importance as a topic.

The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.

Syftet med denna studie är att undersöka hur Karlskrona kommun skulle betygsättas utifrån Sustainable Urban Mobility Plan verktyget ADVANCE. Studien utgår framförallt ifrån forskningsförhållningssättet fallstudier, som framförallt har genomförts med hjälp av metoderna litteraturstudier samt ADVANCE. Litteraturstudierna har framförallt bestått av de strategier Karlskrona kommun har antagit angående dess mobilitetsplanering och ADVANCE har använts som ett verktyg för att kunna upptäcka de positiva och negativa effekter dessa strategier har för kommunen. Utifrån denna fallstudie, samt genom diskussioner med Lars Olofsson (trafiknämnden, Karlskrona kommun), analyseras de resultat som verktyget ADVANCE visar upp, i dessa analyser ges även exempel på lösningar som Karlskrona kommun skulle kunna använda sig av för att kunna förbättra sin nuvarande mobilitetsstrategi..

The main purpose of this study was to investigate which enter- and exit barriers that exist on the banking market for small enterprises located within the region of Gotland. The reason was to examine and identify which barriers that could affect the mobility among small enterprise bank customers on the bank market. To identify the barriers, the study was carried out partly by a quantitative survey with 33 small business owners respondents located at three different concentrated small enterprise areas within the region of Gotland. And partly by qualitative interviews that were conducted with two employees at Länsförsäkringar Gotland Bank.The result indicated that the enter barrier mostly depended on the aspect that business owners of small enterprises believed that bank switching were complicated. The business owners did also consider bank switching as time demanding.

This essay examines the possibilities for the use of ICT for learning in the subject of history. By interviewing history teachers in upper secondary school about their experiences and thoughts regarding the subjects of learning, history and ICT, as well as the relations there between, based on Mishra and Koehlers TPACK model, I come to the conclusion that ICT may enhance learning in history. I also conclude that ICT may create new learning environments in history, where knowledge may or may not grow.The more unique ways of using ICT in history, compared to other school subjects, appears to be the possibility of using a variety of new sources, for example digitized primary sources from archives, that perhaps will motivate students, and make it possible to work from a con- structivistic point of view in history.Other unique possibilities are to satisfy the need of concretizing and visualizing the history being taught, by using a broad range of different media when presenting it. .

Many companies are currently working to optimize and streamline their processes and production lines to achieve higher profitability. In increasingly competitive markets, companies are working to find solutions to increase the value of their production with such a small use of resources as possible. A tool used to accomplish this is the Lean management system. Lean comes from the production system that Toyota has been developing since the early 1900's, The Toyota Production System (TPS). The Lean philosophy helps companies, by working towards continuous improvement in its operations, to achieve higher customer satisfaction, more efficient production and ultimately higher profitability. Many companies are working to implement Lean in their organization. But there are many who fail to implement a complete change towards Lean.

Inledning: Studien är en explorativ kvalitativ undersökning av psykoterapeuters upplevelser i terapier med ungdomar med narcissistisk problematik. Fem psykoterapeuter deltog i kvalitativa intervjuer. Intervjumaterialet bearbetades utifrån en tematisk analys. Genom ett relationellt terapeutiskt arbete går det att få en "genuin" kontakt och bygga allians, men att det också är osäkert och inte en självklarhet. I resultatet framkommer att det krävs tålamod, uthållighet, lång klinisk erfarenhet, goda teoretiska kunskaper samt professionell handledning.

Mervärdesskatten infördes i Sverige den 1 januari 1969 med lagen (1968:430) om mervärdeskatt, så kallad moms. År 1994, året innan Sveriges inträde i EU, infördes Mervärdesskattelagen (1994:200) som anpassats till EG-rätt. Mervärdesskatten är alltid 25 procent om inget annat anges. Kunderna betalar moms till företaget och företagaren betalar in skillnaden mellan utgående moms och ingående moms till Skatteverket. Många företag bedriver blandad verksamhet, det vill säga både momsfri och momspliktig verksamhet som berättigar till avdrags- eller återbetalningsrätt av mervärdesskatten.

This study focuses on carpooling and how carpools can be better integrated into today's society.
