Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.

The transition from a planned economy to a market economy was initiated in Russia in the beginning of the 90s. The three components: privatization, liberalization and stabilization constitute the trinity of the transition theory. This thesis has its focus on the privatization, that also can be referred to as a piratization of Russia. The purpose of the thesis is to explain what went wrong with the privatization, and also why it went wrong. A few men, called oligarchs, got their hands on great wealth which has lead to an abuse of power.

Va?rlden sta?r info?r ett stort vattenfo?rso?rjningsproblem som ma?ste lo?sas ? sa? ma?nga som 884 miljoner ma?nniskor anva?nder idag potentiellt fo?rorenade vattenka?llor till sitt dricksvatten. Denna rapport fokuserar pa? ett av de drabbade la?nderna som a?r Uganda. Syftet med projektet a?r att underso?ka vilket/vilka av de fem olika ugandiska va?xterna; Erythrina abyssinica, Musa spp, Cyperus papyrus, Imperata cylindrica och Coffea canephora som a?r mest la?mplig fo?r rening av kadmium- och blykontaminerat grundvatten.

Dagvatten från vägar innehåller ofta tungmetaller. De vanligaste metallerna i vägdagvatten är bly, koppar, kadmium, nickel och zink. Dessa föroreningar utgör en belastning i recipienter som tar emot dagvattnet. I denna rapport har bly, koppar och zink reducerats från vägdagvatten genom filtrering i kolonner med amorf, granulerad masugnsslagg och sand. Masugnsslagg, som är en biprodukt från framställningen av järn, är en alkalisk produkt med goda sorptionsegenskaper vilket gör den lämplig att använda som filtermaterial för vatten förorenade med metaller.

Diabetes mellitus type 2 and chronic obstructive pulmonary diseases (COPD) are two of the most common diseases in the world and the amount are increasing. The treatments of these diseases are self care and a change of lifestyle. For this to be successful there is a need for the person to have knowledge about the diseases and a motivation for making changes in his or her lifestyle. Most of this information is given by the district nurse at the health centre. It is important to get a better knowledge of these persons experiences and how they used the information given to them.

The purpose of the research is to find out how the teacher of the pre-school looks at the value of the nature Pre-school. To get an understanding of what the nature pre-school enviorment can bring, we are talking about learning, knowledge, and experience combined with the everyday lessons learned from the natural world. The research is a stepping stone on the pre-school teacher?s thoughts and reflections of what a nature pre-school is. This is grounded in a view of how having options for alternative schools lead to wider research, and all conclusions where formed after multiple interviews and analysis.The results showed that the teachers involved are very positive to the nature pre-school environment and learning process.

The integration of the Internet in our society has shaped alot of the things we do in our lives. The Web allows us to achieve certain things directly through our computers, such as reading the paper and paying our bills. But this integration has also lead to another interesting change. Activists have begun to unload their operations onto the Net instead of holding on to the more traditional demonstrations performed in squares. This study aims to look into the world of cyberactivism and examine how cyberactivists experience the way activism has changed as a result of using the Internet.

In organic animal production, synthetic amino acids are not allowed. Therefore, a higher level of crude protein is needed in the diet to pigs, which lead to more nitrogen (N) excreted in the faeces and urine. N can be emitted to the air in the form of e.g. ammonia (NH3), which contributes to eutrophication and acidification and as nitrous oxide (N2O), which is a very potent greenhouse gas. The emission of N can be reduced by e.g.

The main question this bachelor thesis aims to answer is how the public service program Tg1?s news broadcasts may look. The following questions were used to discuss thetendencies of the result: How can the distribution of the news categories appear in Tg1?sbroadcasts? Can the main news be considered as impartial and objective in its linguisticand pictorial representation?To answer the aforementioned question I chose to do a combined study, using aquantitative content analysis and a qualitative content analysis.To lead my research, I focused on two requirements underlined by public servicebroadcasters, namely, objectivity and impartiality, and diversity. The outcome shows thatthe diversity in Tg1?s broadcast is disproportionate and that the pictorial representation isnot impartial and objective without the linguistic part.

It?s known that the drug information patients get at discharge from hospital is often insufficient. Patients? ignorance of which drug they use and how to take them can lead to drug related problems, can cause suffering and heavy expenses.The aim of this study was to shed light on the patients? understanding for drug information, which was given at discharge from hospital. The literature survey was used as a method and based upon a systematic choice of scientific articles, which were found in different databases during the period of April 1 to May 31, 2008.

The leadership within healthcare is a constantly discussed subject. The discussion today is evolving around the physicians' lack of strive towards becoming managers within healthcare organizations. Furthermore the leadership that the nurse practice when becoming manager is on the other hand not discussed. The purpose of this study is to describe important factors of the leadership the nurse practice upon physicians in a healthcare organization as well as to explain why that is. To fulfill this purpose, we have used a qualitative case study research design including a private Swedish healthcare company.

At this point seamen have a lot of tasks of administrative character, beyond the traditional tasks aboard a ship. Due to the new conventions that are formed by IMO, more requirements are added which often lead to time consuming administrative tasks and documentation that should be spent on activities which are contributing to the ships safety. The issue has been observed by IMO that has through BIMCO done a study with the aim to identify and reduce administrative burdens at sea.The primary aim of this study is to find out if safety officers aboard Swedish ferries consider that SOLAS Chapter III, 8.3 och 19.5 regulations are administrative burdens, restricted to muster lists and documentation of training aboard the ship.The secondary questions to the study are if it is possible to remove, combine or change the documents and how much time can be saved by doing this. The question about timesaving could not be answered, because the values were scattered and could not be used for further investigation. The observed values were accumulated by a survey and the result indicated that safety officers did not experience the two regulations as administrative burdens.
