Idag är intresset för högpresterande betong (HPB) växande runt om världen då fördelarna är många, eftersom slankare, tätare, starkare och lättare konstruktioner kan tillverkas. Detta examensarbete handlar om materialförsök och modellering för en typ av HPB som ska användas i husbyggnation. Arbetet inleddes med materialförsök i färskt tillstånd, där god gjutbarhet och konsistens eftersträvades. Utgångspunkten var från ett grundrecept med två olika ballastsorter (slaggballast med flygaska och krossballast från asfaltindustrin med silikastoft), vilka namngavs till pilotförsök 1 och pilotförsök 2. Vidare valdes pilotförsök 1 att provas i hårdnat tillstånd då det visades att det var mer ekonomiskt lönsam eftersom ballasten inte behövde siktas, lägre vct tillhandhölls och att flygaskan som användes i pilotförsök 1 är billigare än silikastoft som användes i pilotförsök 2. Resultaten efter 28 dygn för de materialförsök som utfördes i hårdnat tillstånd var:Tryckhållfasthet; 141,9 MPaDraghållfasthet; 7,0 MPaBöjdraghållfasthet; 10,0 MPaElasticitetsmodul; 46,4 GPaKrympning efter 56 dygn; 0,5 ?Samtliga försök utfördes enligt svenska standarder (SS). Dessutom vidareutvecklas och förbättrades ett redan arkitektoniskt gestaltat Attefallshus ur ett konstruktions- och hållbarhets perspektiv, där fokus låg på transport- och produktionsförutsättningar.

The aim of our study is to explore the empowerment process among micro-business owners in Kayamandi, a black township of Stellenbosch in South Africa. What are the positive and negative implications for the empowerment process? Another aim is to find out the role of local and international support in this process. The theoretical framework of this study revolves around the concepts of gender, power and empowerment. Our methods are qualitative interviews and observations.

On a highly competitive market, quality is an important aspect to take into account, both in terms of goods and services. The Swedish timber market is very competitive and to achieve long-term success focus on the customer, in this case private forest owners, is a prerequisite. SCA Skog AB Jämtlands forest management administration is dependent on the acquisition of timber from private forest owners to fulfil their mission to the supply of SCA's paper and sawmills in Sweden with raw material. To be able to develop the cooperation with private forest owners, the administration investigates their quality management by measuring the customer satisfaction index (CSI). The purpose of the study was to identify a practical and systematic method to handle deviations and suggestions for improvements to achieve a higher customer satisfaction.

 AimThe purpose of this study is to compare and highlight the scope for research into outdoor recreational pursuits in Sweden and Norway. - What are the similarities and differences in the financing of research into outdoor recreational pursuits in Sweden and Norway?- What are the similarities and differences in forums for research into outdoor recreational pursuits in the two countries?  Method The method that has been used in this study consists of qualitative interviews in conjunction with an examination of the published material on the subject. The qualitative interviews have been conducted with six key figures in the field of research into outdoor recreational pursuits in Sweden and Norway where the aim was to obtain a comprehensive overview of the research undertaken in both countries. The examination of the published material has been used to complement the interviews, primarily with information from propositions and reports from relevant organisations and authorities.  Results  Financing in Sweden is spread over several different research councils and authorities where no one organisation has an express responsibility for research into outdoor recreational pursuits. In Norway, however, The Research Council of Norway is the prime source of research funding.

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..

Bakgrund: En bra relation motverkar ångest och depression medan en dålig relation är sämre för den psykiska hälsan än att vara singel. Bra kärleksrelationer består av komponenter som exempelvis nöjdhet, intimitet, kärlek och engagemang. Nöjdhet predicerar dessutom nöjdhet senare i relationen. Kärlek belyses utifrån definitionerna romantisk kärlek, kamratlig kärlek, vuxen anknytningskärlek och medkännande kärlek. Medkännande kärlek innefattar ömhet, omsorg, förståelse, vård, stöttning och hjälpsamhet.

Nationalism during the early 20th century, was often shaped around efforts to create feelings of fellowship within the frontiers. Fellow feelings was considered as a necessity to convince the people that their efforts served mutual goals.Beginning in the 19th century, the European nations experienced a great many projects for this purpose. In the early 20th century the efforts grew. The danger of war and the competition for economic power, contributed the increase of nationalist movements. At the same time, many influential intellectuals also expressed apprehensions about the urbanized way of life; measures were necessary to secure the future success of the nation.The national movements in Sweden, played a prominent role in the creation of a greater patriotic feeling.

Roads and railroads have significant impact on the surrounding landscape and the wildlife living in it. This study aims to provide an overview of the effects caused by railways to reindeer, roe deer and moose in Sweden in order to make more detailed assessments within this topic in the future. The method used is a study of literature on the subject and a synthesis of databases with information about wildlife mortalities, traffic intensity and fences in the study area; northern and central Sweden. The databases were used to compile digital maps using ArcGIS. Infrastructure brings change to the surrounding landscape and its function as habitat for wildlife. Railroads cause barrier effects such as fragmentation, wildlife mortality, loss of habitat and loss of connectivity.

Vid adhesiv cementering, så kallad bonding, rekommenderar fabrikanter att glaskeramers cementeringsyta etsas innan applicering av silan. Att värmebehandla silan med respektive utan etsning, har i tidigare studier visat en höjning av bindningsstyrkan mellan olika material. Den litiumdisilikatbaserade glaskeramen IPS e.max® Press har funnits på marknaden sedan 2005 och få studier har gjorts på ytbehandlingar och dess effekter på materialet och bindningen till olika material. Syftet: att undersöka om ytbehandling med värmebehandlat silan ger en högre bindningsstyrka till adhesivt cement hos en litiumdisilikatbaserad glaskeram, jämfört med kombinationen etsning och silanisering. Material och metod: 12 litiumdisilikatbaserade keramiska block pressades. Blocken delades parvis in i sex grupper och ytbehandlades med etsmedel och/eller silan med eventuell påföljande värmebehandling. Blocken cementerades samman varpå mikrostavar sektionerades fram, som sedan termocyklades. 10 provkroppar ur varje grupp valdes ut för ett microtensile bond strength test. Frakturytorna bedömdes i mikroskop.

Today it is mandatory for every college or university student to pay a union fee to their student?s union. The fee is mandatory and is a payment for writing examinations, receiving grades. The fees purpose is also intended to secure the education quality and student influence. In the presence of the abolishment of the union fee the Swedish student?s unions stand before an uprising competition between themselves and most likely a decrease in membership.

This quality study was carried out with seven semi-structured interviews and five of them were with elite women´s football coaches. What has been studied is how elite women?s football coaches are working with injury prevention training to their knees for the women?s football players. An anterior cruciate ligament injury in elite women?s football is both common and serious knee injury.

Detta examensarbete har genomförts med anledning av att Norrvatten har önskemål om att få en rapport om de material som används i deras vattenledningsnät med fokus på typiska skador kopplade till ett specifikt material eller tillverkningsmetod. Det har framkommit indikationer om att kunskapen om rörmaterial och dess egenskaper med tiden har försämrats då den äldre generationens projektörer efterlämnat en kunskapslucka efter sig.Syftet med rapporten är att ge en god överblick av materialen i Norrvattens ledningsnät. Det krävs kunskap om materialen för att analysera sambandet mellan läckningsstatistik och materialets egenskaper.Informationshalten varierar mellan de olika materialen. Detta beror framförallt på materialets uppbyggnad och svårighetshalten att redovisa en klar och rättvis bild över dem. Materialen och dess information är uppdelade i kapitel för att underlätta för läsaren att på ett enkelt sätt förstå sammanhangen.Ett annat viktigt kapitel i denna rapport är beskrivningen över de anläggningsmetoder som valdes att tas med, dels markförlagda ledningar men också två schaktfria metoder vilka är infodring och rörspräckning.
