The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.

Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

People have utilised and influenced the boreal forest for many centuries. Prior to the industrial revolution during the 19th century, however, human use primarily only had a low impact on the forest. When the timberfrontier swept over the country, the Swedish forests came to change for ever. The study site for this thesis is situated in the northern part of the county of Västerbotten, Sweden, and has previously been a National forest. Today the area is an ecopark and the land is owned by the forest company Sveaskog.

The environmental monitoring in Sweden has been developed by several different parties and is now being coordinated and made more effective in order to meet the current demands on high quality information regarding the state of the environment. Sweden has been divided into five different water districts based on watershed areas because of requirements in the Water Directive of the EU. In Sweden there are two common types of environmental monitoring programs used to gather information on changes in time and in space. Currently both these two types are used for lakes in the water district of the western sea but only one is used for watersheds. The purpose of this report is to supply basic information regarding the possible need for a second environmental monitoring program for watersheds in order to better describe the spatial variation within the district as well as to determine the number of samples necessary in order to describe the district over time and space.

The main purposes of this study were to 1) quantify bacterial production in winter during ice conditions, and 2) to compare these production measures with values measured from summer and open water conditions in three humic lakes situated in northern Sweden. Another purpose of this study was to 3) examine whether clear-cutting significantly affected bacterial production or water chemistry in two lakes situated in catchments were a large part of the forest had been removed through logging compared to an undisturbed reference lake. In winter (March/April 2014), the bacterial production ranged from 0, 7 - 2, 2 µgC/L/day and in the summer of 2013 the production values was 4 ? 10 times higher. The main reason for lower bacterial production in winter was ascribed to lower water temperatures as well as to older and more recalcitrant DOC, as there were no significant differences in total dissolved nitrogen or DOC concentration or -quality, that could explain a lower production compared to summer.

Älvkarleby, landscape character and design proposal is a Graduated Thesis (30 ECCcredtis), in the subject of landscape planning at the Swedish University of Agricultural Sciences, the Department of Rural and Urban Development. This thesis is a study and implement of the method "Landscape Character Assessment" (LCA), developed in England and Scotland as tool to analyse and highlight the landscape in different planning processes. The purpose of LCA is to increase the understanding and strengthen the role of the landscape. The thesis consists of three main parts: landscape characterization, guidelines and a design proposal. The landscape characterization emphasizes the values of the landscape in different types of planning processes, a documentation to base estimations on in any kind of change in the area. Theese estimations have resulted in guidelines that give proposals to the development of the landcape, focusing at the desingproposal.

Syftet med detta examensarbete var att göra en jämförelse mellan uppmätt A-temp och framräknad A-temp. A-temp är ett area begrepp som används när man räknar ut byggnadens energianvändning i kWh per m2 och år, vid upprättande av energideklarationer. För att få fram A-temp kan man mäta upp den men det är också tillåtet att räkna fram den från existerande area enheter. Vilket är lättare och går snabbare men kan ge något fel area värde. Det jag fann i undersökningarna var att för de undersöknings objekt jag haft så är det oftast inte så stor skillnad mellan uppmätt och framräknad A-temp. Störst skillnad blev det i de fall där A-temp räknades fram från BOA och LOA, där den i ett par av fallen uppgick till nästan 15%. För att göra undersökningarna har jag själv, mätt upp A-temp på ritningar samtidigt som jag räknat fram A-temp från existerande area mått som BOA+LOA, BRA eller BTA, därefter har jag jämfört värdena..

This study revolves around the NATO-led Operation Unified Protector in Libya 2011. The military campaign was executed under a UN mandate to protect the Libyan civilian population. Despite the mandate civilians died because of NATO bombings. The purpose of this study is to identify inadequate measures in avoiding civilian casualties during the operation and to continue to work towards minimizing civilian casualties caused by military organizations in international interventions.Early in the operation, NATO?s objective altered from protecting the civilians to over­throwing the Libyan regime. At the same time NATO changed its military targeting.

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

AbstractAimThe aim of the pilot study was to compare short- and long-term effects from group exercise in water with land-based exercise on pain at rest and pain with movement, along with the effects on function in daily life and practice of sports and leisure activities in patients with knee osteoarthritis. The aims were: Is there a difference in short- and long-term effects on pain intensity at rest and pain with movement after exercise in water or land in patients with knee osteoarthritis? Is there a correlation between the degree of pain intensity at rest and with movement, respectively and long-term effects from the two different exercises on function in daily life and practice of sports and leisure? MethodThe study was a randomized intervention study without a control group. Twenty patients with radiographic knee osteoarthritis were under a total of eight weeks treated with either land- or water-based exercise lead by a physiotherapist. The patients rated pain intensity at rest and with movement on a numerical rating scale (NRS) before and after the first training session, before and after the eighth training session, before and after the fifteenth training session and before the last and sixteenth training session.

This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..

Water is vital for all life on earth. But it can also be dangerous, even fatal, if it is polluted water. 60 percent of child mortality can directly be deduced to dirty water. Not only developing countries are affected, even in the western world epidemics are breaking out by partake or bathing in dirty/polluted water.MIP, Molecularly Imprinted Polymers, is a biosensor technology that can provide faster and more reliable response than the current methods of water analysis. It is also cheaper and due to that more samples can be taken and analyzed.

The purpose of this essay has been to explore Alexander the Great from two different perspectives in Greece. The village Proti Serron represents the local area and the national area named Macedonia represents the second perspective. Oral history has been used as a method in addition to literature and trips to museums and archaeological places.As a guideline for the essay and its contents a stereotyped schedule has been created. This schedule is presented below, and it is also possible to read it backwards.The villagers who identify themselves with Alexander the Great from their local area Proti Serron which is a part of the national area named Macedonia.This study proves that the villagers who has been interviewed, identify themselves with the place they live in as well as its history and that they feel that it is their duty to pass this knowledge forward. Alexander the Great is described as intelligent, humble, a man of strength and courage as well as a strategist and sovereign.

Moisture damage in buildings is a serious issue that leads to problematic consequences and high economic costs. Despite the knowledge and awareness existing about moisture problems, extensive damager still occurs today. Studies of moisture in the exterior wall constructions shows that the issue if often caused by rain and water intrusion. These kinds of problem result in major costs usually because the companies have to replace the material and structural components and also in some cases tear down large parts of the buildings.The work includes moisture theory and descriptions of four different exterior wall constructions, wood stud wall with plastered facade, exterior wall with wood facade, exterior wall with concrete, and exterior wall with brick facade. Our thesis work describes how the constructions are affected and moisture damage due to water intrusion.
