In conjunction with today?s increasing competition within the construction sector, more pressure is being placed on building contractors. Efficiency and improvements are necessary but without impairment to an ergonomic and safe construction site. This in is in order to reduce the construction costs and time but to retain the ability to deliver a high-quality contract.Various methods and prefabrication degrees are used, depending on the project's requirements and conditions. This analysis sets out to investigate and exhibit what qualifications are important when choosing a construction method for curtain walls.Advantages and disadvantages with each method have been analyzed and recommendations have been given to show when different methods are best suited.

Purpose: The purpose of this study is to examine different organizations' views on their communicative crisis work. The study will analyze organizations' crisis prevention efforts, its views on the crisis of accountability in relation to stakeholders and to work for a crisis to be elucidated. In order to delineate the study focuses the investigation on various train organizations. Then the concept of crisis is something that circulated widely in the train sector in recent years.Theory: This examination has chosen to use the theory Situational Crisis Communication Theory. It is an empirically tested theory of a collection of different strategies.

Today 70 percent of the world's sand beaches are under recession due to erosion. The global warming may have the effect upon the sea level increasing and the erosion increasing on the sand beaches. To save these sand beaches, the erosion must be prevented. Coast erosion shelters like gabions and sea walls are functioning extremely well to protect the land behind the sand beach, but due to the wave reflections, created in front of these so called hard erosion shelters, the erosion of the front beach is accelerated. During the last decades, artificial sand supply (beach nourishment) has been the adopted praxis.

In the centre of Bromma, east of Brommaplan is the part of Bromma named Riksby. Riksby was built in the early 1940:s as a part of the westward expansion of Stockholm. Other places that were built at the same time was for ex. Stora Mossen and Abrahamsberg. This work is about the outdoor environment of the housing co-operative of Brickbandet.

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through Restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

The study investigates questions and considerations emerging when stone in historic buildings needs to be replaced. The focus is on the surface treatment of stone in sandstone façades in pre-industrial buildings. That means buildings constructed by traditional methods and craftsmanship without the use of modern technology.The research issue originates from the extensive stonework that is planned for the façades of the Stockholm Palace. The project includes the replacement of large quantities of damaged stone to newly cut stone. This raises the questions about the use of modern and rational methods for surface treatment on the replacement stone.

Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and Restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

Carbon sequestration through Restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

Not enough attention has been paid to the correlation between the failure of peacekeeping operations and the actual source of civil wars. This text is an attempt to fill that gap. Hence the question: under which conditions is it possible for peacekeeping operations to replace the responsibility of the state concerning the security aspects of the social contract? The outset of the text, using the theories of Robert Nozick, is a theoretical approach towards the founding of states, described as the merging of entities. The theory serves a purpose since it, in combination with identity, illustrates in what manner the glue of society occurs and the rallying around other kind of loyalties like clans and ethnicities.

Idag är många städer belägna längs kusten och när städerna växer innebär det att stora ytor våtmark försvinner. Våtmarker i urban miljö kan genom rätt utformning erbjuda varierade miljöer med ett antal värdefulla ekosystemtjänster. Exempel på sådana ekosystemtjänster är vattenrening, omhändertagande av stormvatten, kvarhållande av näringsämnen i marken och möjlighet till rekreation i grönskande miljöer.1 Att anlägga våtmarker i en urban miljö kan innebära ett värdefullt utbyte mellan människa och natur. Dock kan det finnas utmaningar kring att kombinera en rik biologisk miljö och en urban miljö med människans förväntningar på tilltalande estetik och möjlighet för rekreation. För att urbana våtmarker lågsiktigt ska restaureras och anläggas i stadsmiljö krävs det att de accepteras av stadens befolkning.

Idag tillämpas den s.k. bruksvärdeshyran som har sin grund i att lägenhetens standard avgörhyran. Företagets produktionskostnader ska ej tas i beaktande vid ett bruksvärdessystem. Detmedför både för- och nackdelar för hyresgästen. Om företagets kostnader överstigervärderingen av de standardhöjande åtgärderna kan detta inte åläggas hyresgästerna samtidigtsom hyresgästerna ej ålägger en hyresrabatt när åtgärderna kan avses avbetalad.

Gothenburg municipality has a lot of natural water. This paper enhances the function and importance of water in the city. It also deals with the problems of sewage water and flooding. Gothenburg has reached an advanced stage of water planning. By developing a Waterplan, the municipality highlight that water has an important position in the urban planning.

The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.

Titel: Human being and Christian ? creationtheology of Gustaf Wingren.Analysis of an accentshift from a juridical theological metaphor to a biological theological metaphor.Author: Tove Pilroth.The purpose of the essay is to analyse the meaning and the consequences, in a critical and constructive way, of an accentshift of interpretation and understanding of the gospel, from a juridical theological metaphor to a biological theological metaphor. The purpose is presented in the frame of the creationtheology of Wingren. To be able to make the research and to answer the purpose of the essay, the following questions are essential:The human being is captive and redemption is liberation. If we are serious about that the gospel gives the human being rehabilitation, satisfaction, liberation and a life and a future with God, the essential question is which metaphor, a juridical or a biological, that speaks to the human being in the best way? What is the meaning of an accentshift from a juridical to a biological metaphor? How does the creationtheologhy of Wingren, from a biological metaphor, meets the situation of the existence for the human being, her longing for life, health and meaning? What kind of theological resources are present in the creationtheology of Wingren, in the confrontation with future theological challenges?The essay is stressing the need of pluralism in the interpretation of the gospel.
