Kvicksilver är ett av de farligaste miljögifter vi känner till. Regeringen har därför arbetat fram ett förslag till förbud mot kvicksilver som kemikaliereagens från år 2004. Detta förbud innebär att många laboratorier måste byta analysmetoder. Vid analys av CODCr används kvicksilversulfat för att minska interferens från klorid. Bravikens pappersbruk använder en CODCr-metod som innehåller kvicksilver.

C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.

Earlier research has shown that young and adult citizens in Europe participate in politics in different ways. While adult citizens participate in more traditional ways, non-traditional ways are more frequent among younger citizens. Moreover, issue-based participation increases when Europeans turn away from mainstream politics. Citizens in the European Union EU-15 between 15-24 ages are likely to be ?critical? citizens of a working democracy compared to people in older ages (Sloam, 2016).

This paper is a literature review that examines how good mental calculation skills benefit pupils, which could work as a valuable learning tool for future teachers. The study addresses four key questions: ?What are the advantages of proficient mental calculations??, ?What strategies exist for mental calculation skills??, ?How can teachers accommodate their teaching to develop pupils? mental calculation skills?? and ?What has arithmetic looked like in different eras and what algorithms have been used??. Through literature searches in search engines, scientific articles were found, which formed the basis for the result segment. This was divided into two parts: A historical and a didactic overview.

I denna rapport undersöktes S&P 500 Energy Index genom multipel regressionsanalys. Modellerframställdes genom regression och baserades på data hämtad från börsen. Modellerna angavs iprocentuell ändring respektive absolut ändring. Validitet för varje enskild kovariat testades och en risknivå avgjorde om en kovariat skulle inkluderas i modellen eller inte. Detta ledde till två modeller med bättre kurvanpassning till den givna mängd data över det valda energiindex.

In the care for the critically ill patient the next of kin is of great importance. Their support, love and care for the patient, increases the wellbeing and makes a connection to the patient?s normal lifeworld. For the next of kin to be able to be that support the next of kin needs to be helped to maintain the basic need of for example their sleep, food, hygiene and psychosocial support. The critical care nurse must see to the patient?s whole lifeworld which includes their next of kin.The aim of the study was to identify the resources available for the next of kin in intensive care units in Sweden.

The purpose of this essay is to raise and discuss children?s problems with concentration in two areas, stress and Adhd, where the symptoms are similar to each other. During recent years I have experienced how "difficult" children increasingly have been diagnosed and "stamped" with various combinations of letters. Because of my own children?s diagnoses, this has raised my interest in studying children´s modes of expression and behavior, and I have come to question whether many children who receive a diagnosis of Adhd really are afflicted by it.

Studien baseras på en kvantitativ metod med starka kvalitativa inslag. Syftet med studien är att med hjälp av ekonomisk teori och ekonometriska modeller försöka bestämma efterfrågeelasticiteten på Internetpokermarknaden. Vi har i studien utgått från att efterfrågefunktionen på Internetpokermarknaden är en konstant elastisk nyttofunktion. Då priset i Internetpoker är en komplicerad variabel att skatta konstruerade vi en prisformel. För att kunna vikta de olika variablerna som ingick i prisdefinitionen genomförde vi en surveyundersökning.

Lack of political interest and will to deal with human rights violations carried out under the civil- military dictatorship, has characterized the transition and post-transition in Uruguay. The systematic use of torture, arbitrary imprisonments and forced disappearances in the relatively small country created a culture of fear that has been present through out the post-transition phase. Human rights groups have been central actors in the fight for truth and justice and against impunity. This study analyzes how these groups multiple democracy-building functions have contributed to democratic development. It also analyses how the democracy-building functions have been constrained by the political context.

How capital structure influences corporate performance and value has been in the interest of researchers and scholars for more than half a century, but an answer is yet to be found. The main objective of the present paper is to contribute with data for this cause and hopefully help to clarify this mystery. The method that was used was by analyzing the impact of debt on profitability and market valuation through linear regression. The study examined 17 Swedish property companies listed on Nasdaq OMX Large Mid and Small Cap over a 6 year period (2007-2012). The authors found a slightly negative relationship between debt-to-equity and profitability measured by return on equity (ROE) as well as by return on assets (ROA).

A common assumption in marketing is the wider variety of product a corporation has, the better for the consumer: more product - more choices. Companies often develop a line extension to broaden consumer range through product attributes including quality, function and design. These developed attributes within the product are not always optimal for the consumer. As a result, companies often become entangled in having a price higher than the cost and benefit of the products. This essay aims to analyze the consumer value of line extension products and how these evaluations relate to extended line product pricing.

The store manager can make great benefits of having an eye on how the staff works towards the customer, because the personnel is an important tool when competing with other stores. This paper is focusing on the part that relates to the staff in the store, which is one of the key tools in the competition for customers after the customer made it to the store. Many stores have guidelines which the staff should follow when they meet with customers. If the staff is too tightly controlled by these guidelines, customers can perceive the first encounter with the staff as artificial and as if the genuine friendliness does not exist. It is important that the staff looks at the individual customer and treat every customer in a personal way and that the staff can see the customer?s needs.

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

The purpose with the examination is to examine a preschool head and three teachers experiences and opinions of whether the tablet can be used to support childrens linguistic development and social interactions in preschool.
