Olika metoder och tekniska hjälpmedel för att bestämma bevattningstidpunkt :

This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.

Kallbad som turistattraktion : En studie om destinationsutveckling av Stockholms stad

Stockholm is considered as a tourist destination which has a lot of offers to attract tourists and if it utilizes it water better it can give a wonderful and unique experiences and cold baths may become an image to it.The aim of this study is to shed light on the open-air swimming-baths and shores of Stockholm. Also how to use this advantage as it?s a city based on many islands, the purest water in Europe and this makes Stockholm as a destination a very attractive place for tourism. For a better understanding of our study, we have studied the quality and quantity to see how people began to exploit open-air swimming-baths throughout history everywhere in Europe and specifically of Stockholm city sea shore. We did a study on the history traditions of open-air swimming-baths and how it can be a tourist attraction through books and interviews, scientific articles and our personal observation, so that we can analyze how to develop sustainable tourism in the future and how Stockholm city can make development of opportunities for the future.

Design Program for Dessie Campus, Wollo University, Ethiopia

A geographical position and its social, cultural and political context as well as climate and specific physical characteristics define the scope for a landscape design project. This has become clearer for us in our master project where we have made a Design Program for the outdoor environment of Wollo University in Dessie, Ethiopia and analysed and reflected on the work and process. The aim for the project has been to design an attractive and functional outdoor environment for the Campus, based on the inventories and the needs and wishes of clients and users. But, the aim has also been for us as landscape architect students to gain a greater knowledge about landscape architecture and the design process by position ourselves outside our usual context. The method has been open and seeking where the site, literature studies, dialogues with people and our own experiences from the field study in Ethiopia has influenced the work. Wollo University is situated 400 kilometers north of Addis Ababa, in a mountainous landscape. It faces problems of heavy rainfall during the summer, soil erosion, a lack of essential facilities, and is still a construction site with empty spaces in-between buildings and infrastructure.

Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes

Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.

Statlig eller privat vattenförsörjning? : En debattanalys

The purpose of this essay is to illustrate the debate of water politics and privatisation of water distribution. My method is debate analysis and qualitative idea analysis and for my essay I used three books that try to persuade the reader that his or her idea is the best for this water crisis. My main question is to illustrate the debate concerning water privatisations. I will also look at the arguments for or against privatisations and finally determine how the authors think the state should act towards this subject. The first book I used was Vandana Shivas ?Water Wars? that when published started an international discussion about the water privatisations.

Utveckling av kyl- och smörjsystem för ekobilen Agilis HCCI motor

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.

Leva med Lean : Hur involveras och motiveras medarbetare till att ständigt arbeta med förbättringar?

The European Union is struggling to maintain democracy and tries to increase the participation among the citizens in Europe. The European Citizens? Initiative, ECI, is a platform established by the European Commission to allow citizens to propose new legislation. ?Water and sanitation are a human right! Water is a public good, not a commodity!? is the first ECI that has met the requirements.

Varför är Bivarödsånsvatten så brunt?

The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.

Samkörning mellan värmepumpar och fjärrvärme : Bostadsrättsföreningen Bogården

This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.

Anpassning av VOD-tjänster för breda barnmålgrupper : EN ANVÄNDBARHETSUTVÄRDERING AV BARNPLAY UTIFRÅN MÅLGRUPPEN 3-11 ÅR

This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

Översvämningsmodellering av ett dagvattensystem

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten

In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

Identifiering av parametrar för tillståndsbedömning av en vattenkraftstation

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

Barns tankar om älven : Förskolebarns förståelse av älven och vattnets miljö

AbstractThis research is about pre-school children?s conceptions of the river and the water environment. The aim of this study was to apply a new teaching method based on the outside learning, as well as to test the method and see if it works, i.e. if children get more knowledge this way compared to ordinary methods like teaching in the class-room which involves showing pictures and discussion of them.The main questions in this study were how children get new knowledge through outside learning and how effective this learning method is, i.e. how much they noticed and learned about the river and the water environment as a result of that outside observation.

Simulering av energieffektiviserande åtgärder för små- och flerbostadshus : Möjligheter för JM:s hustyper att uppnå passivhuskonceptet vid nybyggnation

The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.
