Dagvatten i Märsta : förslag till anläggning för ekologisk hantering samt metodöversikt

Stormwater in urban areas has been treated as a problem for a long time. The large proportion of impermeable surfaces inhibits the water from infiltrating in the ground to the same extent that it does in nature. This causes intensive surface flow during rain, which in turn causes inconveniences such as decreased accessability, floods and increased risk of desease spreading. Drainage through pipes is the traditional and usually functional metod for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation.

Förnuftets chiaroscuro : Om möjlighet till kunskap om Gud enligt Thomas av Aquino

This academic essay explores the possibilities to knowledge of God in the thought of Thomas Aquinas. The essay takes its departure from question 12 in the Summa Theologiae, specifically articles 12 and 13 that deal with natural knowledge of God and supernatural knowledge, respectively. It also presents objections made by modern philosophers against these ways of knowledge along with a rebuttal of these objections. Lastly, a conclusion is offered and ends with a reflection on how Aquinas' teaching on human knowledge of God in earthly existence compares with his teaching on the knowledge human beings will have in heaven and what consequences that has for our present knowledge..

Lag i katolsk och luthersk teologi : Om lagbegreppet i Wolfhart Pannenberg, Dietrich Bonhoeffer, David P. Scaer och Johannes Paulus II encyklika Veritatis Splendor

Three main questions give the fundamental structure for this master thesis: 1) In what way is the notion of law being perceived in the following theologians respectively; David P. Scaer, Dietrich Bonhoeffer and Wolfhart Pannenberg? 2) In what way is the notion of law being perceived in the encyclical Veritatis Splendor? 3) Which similarities and divergences can be found in the respective expositions of the notion of law?For the purpose of comparison, I have employed four questions of analysis. These are: A) What is ?the law?? B) Is the law being effected, or is it working, in the world and if so - in what ways and for what purposes is it meant to serve? C) Does human beings have any capacities to understand and/or live in accordance to the law? D) Does the Gospel, perceived as the earthly life, actions, death and resurrection of Jesus Christ, effect any alteration with respect to the purpose, range, function or interpretation of the law?In order to better understand Roman-Catholic concepts of law, the treatise on law of Thomas Aquinas Summa Theologica is briefly presented.

Application development for touch-screen interfaces

The way we interact with computers will soon change dramatically. The input interfaces are becoming more and more intuitive and one of the latest technologies is a touch screen interface capable of dealing with multiple inputs simultaneously. The tools we use to communicate with the computer - such as the mouse and the keyboard, will slowly disappear and be replaced with tools more comfortable and more natural for the human being to use. The purpose of this project was to create a basic framework for future projects dealing with this interface, as well as creating some example programs. This report describes my work and my experiences with this new interface..

Förfädernas berg? : en tolkning av fornborgen på Halleberg

The essay deals with the hill-fort on the mountain Halleberg, Sweden, its wall design, functionality, dating and its possible function as a central location and a place of worship of the ancestors.The Halleberg hill-fort consists of a 1500 meters long at times cohesive stonewalls which together blocked the mountain from its surroundings. Hallberg's natural vertical scree and cliffs along with the masonry blocked the whole mountain from the surroundings.The hill-forts, with few exceptions are largely not investigated archaeologically and its functionality and role in the ancient society is based on outdated research on the subject. The current archaeological interpretation is that hill-forts served as temporary defense in times of unrest or served as center of power for a social elite. The prevailing view in the archaeological sphere is that the hill-forts had a variety of functions and that its functionality and role in ancient society has varied.Halleberg´s strongest wall sections are at the mountain's south-eastern part where the natural driveway, Storgårdsklev is located. Along with the massive masonry of the walls in Bokedalen Storgårdsklev functioned as the hill-forts main entrance.

Modeling of Natural Human ? Robot Encounters

Studiens syfte är att belysa teknikens mångfald samt att analysera hur man kan väcka barns intresse för teknik och hur man kan skapa inlärningstillfällen i förskolan. Undersökningen bygger på en litteraturstudie. Forskning och teknikprojekt har studerats. Resultatet visar att framför allt förebilder, teknikmedvetenhet och undervisningsmetod har påverkan på barns teknikintresse. Vidare behöver barn komma i kontakt med gammal, enkel och synlig teknik, vilket man kan utgå ifrån vid planering av förskoleverksamheten i teknik.

Uppfölining av naturvårdande skötselåtgärder(NS) i ekopark Storklinten

This study's primary purpose was monitoring of conservancy operation measures. The fixed sections within ekopark Storklinten owned by the forest company Sveaskog. These measures are performed with the purpose of creating and maintaining hardwood forest and mimic natural processes. The sections were divided into different categories depending on the type of measures they were exposed with. The monitoring showed that the purpose of these measures was fulfilled in general.

Järnåldersboplatser och historiska byar : En studie av agrara bebyggelsemönster i mälarbygder under 1500 år

Following paper deals with the questions about prehistorian and medieval settlements in the Mälar Valley and their relations to the historically known hamlets or single farmsteads from the 17th- and 18th-century cadastral maps. Models over settlement development through the period A.D 200 to 1700 done by geographers Ulf Sporrong and Dan Carlsson are tested and compared to the knowledge won by recent archaeological excavations. Is there a connection between the older settlements linked together by dry-stone walls and the late Iron Age settlements? Does the picture differ from the one presented for the Gotland region? How well are the general theories about different settlement development depending on basic natural conditions as for the potentials for cultivation and topography, corresponding to the physical remains?  Are there other factors involved when the settlement structure takes its form?The methods that are used here constitutes mainly of a comparison between different locations in the Mälar Valley that has got a well known prehistory thanks to extensive archaeological excavations. Cadastral maps, soilmaps, topography maps and maps over ancient monuments are intertwined to the same map and analyzed through works in Geographical information systems.The results of this study reveal an interesting suspicion in the continuity-question through the Iron Age.

Allt har förändrats men ändå ingenting

Everything has changed, yet everything is the sameUsually, there is no reason for people to think about death or illness, although it is a highlynatural part of life. Most people live in health without major problems. When something does happen, people assume it will be at the end of their life and then it will be a natural part ofgrowing old. Yet some will get the notice or the feeling that something is not the way it should be, it can be something they can live with or they may have to face death.The work concerns the body?s fragility and feelings about human vulnerability.

Asymptotiska egenskaper för Lanczosspinoren

Asymptotically flat spaces are widely studied because it is one natural way of describing an isolated system in general relativity. In this thesis we study what happens to the Lanczos potential at spacelike infinity in such spacetimes. By transformations of the Weyl-Lanczos equation, we derive expressions for the limiting equations on both the timelike unit hyperboloid, and the timelike unit cylinder. Finally the Newman-Penrose formalism is used to get a component version of the equations..

How can the business potential of products with health claims increase?

The purpose of this master thesis is to investigate the influencing factors on the businesspotential of products with health claims, using PrimaLiv as an example. And togive recommendations on how a dairy producer, which is present in the Swedishmarket, could improve the sales rates of products with health claims. We have chosento put a main focus on the consumer, as he or she determines the business potential.This is an unusual approach since most studies cover the producer?s perspective. Wethereby wish to contribute with new knowledge on the area in question.

En bra plats för lek : kreativ och tillgänglig lekplats i Hedemora

For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play. A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose irregular forms and structures can become interesting elements to explore. Vegetation also gives sence-experiences of various kinds, materials like twigs and leafs to play with and a place to play house.

Den bortglömda krisen ? en kritisk diskursanalys på nyhetsrapporteringen av Centralafrikanska republiken
