"democracy in doses"? - en studie kring demokrati och Egypten under Mubarak

AbstractWhy don't (some) regimes with formal democratic features undergo transition to democracy? Which are the internal dynamics of these regimes that can offer comprehension to this state of affairs? The main purpose of this thesis is to advance the above questions, and, on a lower level of abstraction, examine the case of Egypt. The Egyptian regime is characterized by, for instance, a multiparty-system, steps toward economic liberalization, and some level of persistent state opposition, and has been considered on the way to liberal democracy, but can still hardly be estimated as such.Thus, the thesis takes part in a theoretical framework on democratization, and further analyzes the case of Egypt on grounds of socioeconomic development, political culture, and class configuration. By this contextual approach, the thesis adduces that a low level of modernization, an incomplete democratic political culture, and a bourgeoisie supported by the state are impending significant factors. The thesis additionally remarks on the interconnection of the adopted theories, and discusses a potential need for new theoretical propositionsA secondary aim of the thesis also gives some insights into the concurrence of regime stability and the absence of democracy in, what often could be labelled, authoritarian regimes.

Standardisering av dragarinstallation

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.

Plan för multifunktionella buffertzoner längs Vramsån påMalörten AB : s jordbruksfastigheter

To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.

Stärkelsers funktion som konsistensgivare vid olika temperaturer i pulversoppa : en experimentell kvantitativ studie

More often consumers demand instant dry soup that can be prepared with a water temperature below 100o C, which is currently not possible, because the dry soup becomes too thin when using water with a lower temperature. In this study, various kinds of starch studies were made to optimize the starch used in the existing product to make it more viscous at both high and low temperatures. The result was that one of the two starches present in the existing product was retained by change in quantity as it contributed to important flavor parameters. The second was removed and replaced with a starch that made the product more viscous at lower temperatures. To find out if the new product differed from the existing product a viscosity measurement and a sensory paired preference test were made.

Varför läxor? : En studie över, vilken syn några lärare i grundskolan år 7-9 har på läxor

AbstractIn the research made on the subject, homework, there are a lot of differences in the opinions regarding the meaning of homework/home assignments in the educational system today. Do they fill a purpose or do they only create social rifts and injustice.For my essay I chose to find out what attitude senior-level teachers have towards homework and what meaning it is considered to have on the students learning ability.My research is based on interviews with six senior-level teachers who all teach different subjects.The results showed that all of the interviewed teachers used some kind of home assignments in their teaching.Ultimately, the conclusion I reached is that the homework should be well prepared and given a lot of thought. The homework should also be interesting and meaningful to the students to promote the learning process..

Neuropsykiatriska funktionshinder och missbruk: de professionellas syn på riskfaktorer och skyddsfaktorer ur ett utvecklingsekologiskt perspektiv

The purpose of our study is to examine what risk factors can contribute to a child/youth with neuropsychiatric disorders developing an addiction to drugs. We also wanted to find out what protective factors can contribute not to develop an addiction. In order to find out these two different aspects we interviewed twelve professionals to get their view upon the matter. The professionals work within different sectors such as school, healthcare, social services and one of the interviewed is a member of an organization that specialises in neuropsychiatric disorders.When analysing our result of the interviews we used Bronnfenbrenner´s theory on the ecology of human development. What we found was that there are significant risk factors and protective factors on different levels of the child's environment.On the first level, the microsystem, interpersonal relations have an impact on the child's development.

Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro

The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.

Cytologiska bedömningens påverkan på analysen av bronkoalveolärt lavage (BAL) samt förhållandet mellan andelen mastceller och proinflammatoriska cytokinmediatorer i BAL hos häst :

Inflammatory airway disease (IAD) is a respiratory disorder that most commonly affects young horses performing at a high level. The clinical signs are often mild but the disorder can cause a marked decrease in performance to a point where the horse has to be taken of training and competing. The aetiology underlying IAD is not yet fully understood. One current theory is that a type I-hypersensitivity reaction due to allergens in the environment is the cause in some horses. The most reliable diagnostic method is a bronchoalveolar lavage (BAL) since it reflects the inflammatory status in the most distal parts of the lungs, which are affected in IAD.

Fl?ckreducering ? Bl? Vinranka En j?mf?rande studie av tv? efterbehandlingsmetoder vid reng?ring av glaserad keramik

This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.

Trädgårdar på tak- och gårdsbjälklag :

The purpose of this thesis is to collect knowledge of techniques and materials for planning roofgardens. Gardens built on top of buildings is not a new phenomenon, already in the beginning of the century architects were experimenting with roofgardens. During the Modern Era roofgardens appeared as a part of the design and worked well together with flat roofs and the ideas of light, air and greenery. Today the most common kind of roofgarden is on a ground-level joist that hides parking or other underground functions. The most important difference between planning a roofgarden and a garden on the ground is the limitation of the load of the roofgarden. Plants, paving-material and equipment must be chosen with this in mind. A light and thin layer of soil demands plants with small needs for water and nutrition.

Utvärdering av miljönytta för olika miljöcertifieringssystem för byggnader : En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö

This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.
