Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness
A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..
OTEC-Ett energialternativ för enhållbar ö
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
"Det bästa med skolan" : En elevinriktad studie om motiv och attityder till internationella utbildningsutbyten.
In Sweden, little research has been done on the topic of international exchange programs that various schools offer to their pupils. This study investigates how pupils view these exchange programs, and how in their opinion it affects their learning and their level of motivation. The study also investigates the motives for taking part in or declining an international exchange. To answer these questions a quantitative survey and qualitative interviews with pupils with and without experience respectively was carried out.The study indicates that pupils that have not taken part in an exchange believe that it is a time consuming quest that may affect the student?s results in other courses, which is not a belief shared by the other group.
En utredning om effekterna av Skogsstyrelsens röjningsrådgivning
This is a study on the outcome of the Swedish Forest Agency´s mission to provide individual advice to private land owners about precommercial thinning. The study was conducted in Sala municipality and included forest owners that had received private individual advice from a Swedish Forest Agency consultant as well as forest owners that had not received individual advice. One of the central issues was to make comparisons between these two groups. The survey was carried out by telephone interviews combined with a smaller field study. The questions were designed to provide information about to what degree the forest owners had been affected by the advice and if there had been a change in the way in which precommercial thinning was performed.
In terms of the amount of precommercial thinning that had been carried out, no statistically significant differences were found between the two groups.
Store Image Perceptions in International Retailing: an Empirical Comparison of IKEA?s
It has been found that customers in the home market perceive the retailer?s store image more positively than customers in the host market, even though this study has found that theretailer?s store image is generally perceived very positively by customers in both examined markets. In addition, this thesis has found that there is a significant difference in how IKEA?smanagement and customers perceive its store image. It can also be concluded that IKEA management perceived store image more positively than customers.
Passivhus ur en brukares perspektiv
Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.
Kulturarvets skydd i väpnade konflikter. Kulturarvsbrott vid ICTY
This graduation thesis aims to give a survey of how cultural property is protected withininternational law and how these protections worked during the conflicts in the formerYugoslavia and later at the International Tribunal for the former Yugoslavia, ICTY.Cultural heritage is important symbols for ethnicity, religion or political views. Because ofthis cultural property has been targeted in armed conflicts as long as can beremembered. The protection of cultural property within international law has developedfrom the midst of the 19th century up til today and is still developing towards strongerprotection. One of the latest armed conflicts where the cultural property became targetedwas the wars in Yugoslavia in the 1990?s.
Judendom i läromedel En diskursanalys av fyra läromedel i religionskunskap
This is a study that aims to discern whether there are any differences between upper secondary level school textbooks published both before The Living History Forum (a government agency that works with issues on tolerance, democracy and human rights) was founded and after with regards to their depiction of Judaism in general and anti-Semitism and the Holocaust in particular. Underscoring the relevancy of this topic, in 1997 CEIFO (The Centre for Research in International Migration and Ethnic Relations) and Brå (Swedish National Council for Crime Prevention) conducted a survey among school children which revealed a lack of knowledge regarding the Holocaust (including whether it had even occurred). With this educational deficiency in mind, this study attempts to determine if there is an active development in text-book authoring regarding this subject.Using Norman Fairclough's critical discourse analysis (CDA) eight textbooks (four old and four new) are examined and compared in order to see if there have been changes in discourse regarding this topic over time. Fairclough's critical discourse analysis is a method used to analyse the relationship between discourse and changes in social and cultural development, and is thus employed in this case to determine if any significant changes have been made in textbooks regarding this topic.As a future teacher in religion it is important for me (and others) to be aware of this type of issue in order to be able to combat it when encountered in schools. It is also important, and part of one?s responsibility as a teacher, to actively and critically work with and review textbooks.This study has not found any major changes in the depiction of Judaism and anti-Semitism in any of the textbooks reviewed.
Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal
Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.
Investeringar i privat och kommunal verksamhet : En studie om faktorer som påverkar investeringar
The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.
Solenergi på Nya Karolinska Solna
In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.
Har forskningen om internationella relationer någon praktisk betydelse? : En studie om idémakt i utrikespolitik
The aim of this paper is to get a deeper understanding if research about international relations has any practical meaning. The main focal point is about the importance of the scholar idea soft power, and its meaning on foreign policy actions through expressions. A quantity and quality method is used. The point of the main theory that concerns international relations takes a rationalistic perspective, and expands it to the notion that ides can have an impact on policy outcomes. Three different types of research utilization can be traced to determine in which way an idea is getting implemented.
Internationellt erkännande : En studie utifrån Syd Sudan och Somalilands självständighetssökande
The intention of this study is to investigate why some regions, which choose to secede from their parent country, are internationally recognized and others are not. The case studies of this study are South Sudan and Somaliland. South Sudan is as of now the world?s newest state, and Somaliland is a break-away state that is considered a part of Somalia by the International community. There are conditions that have to be fulfilled, before existing nations recognize the break-away state, such as an agreement between the seceded state and the parent country, which was the case for South Sudan and Sudan.
Metaller i dagvatten - Effekter i recipient : En analys av koppar, kdamium och zink i dagvatten från en parkering i Halmstad, Sverige
When stormwater occurs near human activity the water gets polluted. The purity and composition vary widely depending on the types of activities in the area, the type of surface the water comes in contact with, precipitation and many more parameters. It has long been known that stormwater quality can affect both human health and the environment as stormwater is a major contributor to pollution of receiving waters.A human activity that has an impact on the environment in several different ways is traffic and stormwater is no exception. Airborne gases that react with precipitation, oil leaks and fuel systems that drops down on the ground, metals from brake linings and rubber particles from tire wear are some of the aspects you have to take into account when categorizing the relationship between traffic and polluted stormwater.In this project, stormwater samples from a parking lot in Halmstad, Sweden were collected and analyzed with an atomic spectrophotometer. The presence and relationship between copper, cadmium and zinc with different rainfall parameters have been studied.
IT, mat och miljö
Shopping for groceries often means that, as consumers, we travel to the grocery store ourselves, by ear, bike or on foot. At the store we pick out the groceries that we want, go the register and pay for them. During the last couple of years consumers in Sweden have been given the opportunity to let someone else select and transport the groceries to their home instead, so called home shopping. As this report is being written, the possibility to buy groceries this way is somewhat limited, but many forecasters believe that in the near future it will increase immensely. Because of the large volumes of groceries that are being transported, there is great transport work being done in the supply chain.
