The fit of all-ceramic crowns produced using different digital impression systems

Syfte: Att jämföra marginell och intern passform på kronor framställda genom fyra olika digitala avtryckssystem med kronor framställda genom konventionell avtrycksteknik, som kontrollgrupp. Metod: Femtio helkeramiska kronor framställdes från 50 standardiserade provkroppar, som delades in i fem grupper, där varje grupp representerade ett avtryckssystem. Varje krona cementerades på sin respektive provkropp och sektionerades till fyra segment. Den marginella och interna passformen mättes i 8 fördefinierade punkter. Totalt 1567 mätningar utfördes, analyserades och jämfördes. Resultat: (1) Gällande marginell spalt kunde inga signifikanta skillnader hittas då kontrollgruppen jämfördes med vart och ett av de digitala systemen. (2) Lava? hade mindre marginala spalter än CEREC® och iTero®, (3) CEREC och Lava hade mindre spalter i chamfern jämfört med iTero och kontroll, (4) E4D® visade mindre spalter än CEREC i mätpunkter 4-8 och CEREC visade en mindre spalt i mätpunkt 2, (5) Lava visade mindre spalter än CEREC i mätpunkter 1, 3 och 5-8.

What goes up must come down - Modelling economic consequences of wind turbine decommissioning

At the time being there is limited experience within turbine decommissioning in Sweden and the economic effects are unknown. Despite this, there are expectations that revenues generated by sales of materials will cover decommissioning costs. The model developed identifies thirteen parameters that vary between different types of turbines and that affect the economic consequences of decommissioning. The three most important parameters are turbine location, tower material, and the scope of decommissioning. Trends in the wind energy industry show that these three factors are developing in a manner that increases decommissioning costs dramatically.

Visioner om framtidens profilboenden : Hur äldre personer vill bo när det bli ännu äldre

As the population of senior citizens increase, various housing options are required for an increasing competitive environment within elderly care. This study addresses the concept of profile housing for the elderly by outlining its definition and providing options for the different kinds of housing options available within the municipalities of Stockholm and Solna. The study reveals that these locations have different definitions of what constitutes a profile home. Based on this, should one assume there are further definitions to cover additional municipalities?     This study also touches upon how a group of senior citizens would perceive their living conditions if relocated into such housing. Members of the group have also expressed that they would like to go about their daily activities as they have prior to being relocated. They want health professionals to enable and encourage participation in various daily activities..

Konstruktioner av kvinnligt och manligt i våldtäktsdomar : En kvalitativ textanalys

The purpose of this study is to examine constructions of plaintiff [woman] and the defendant [man] in Swedish rape convictions from 2013. The cases in this study cover acquaintance rape. We also intend to analyze the constructions of the sexes in relations to each other. The study is completed by a qualitative text analysis, with inspiration of a hermeneutic interpretation. The result is presented by four categories: the worthy of protection of the woman, the penalty of the man, the complicity of the woman and credibility.

Familjehem med konsulentstöd : En kvantitativ studie om konsulentstöd till familjehem

The main aim of this bachelor thesis is to describe through a quantitative study the extent of support received by foster families, their opinion of the support and any areas that might need improvement. The foster families receive foster care support through a private agency. We concentrated on the following areas of support; education, health, contact with the children?s biological relatives and behavioral difficulties. These four areas have, in previous research, shown to be problematic for foster children.

Beslutsfattande vid anbudsgivning hos svenska byggentreprenörer

This thesis examines the tendering process from the point of view of Swedish building contractors. The purpose with the study is to chart the decision process for the contractors during the tendering process. The study is designed as a survey study. This made it possible to reach a wide base of respondents, not letting such factors as geography being an issue. The survey itself was characterised by a very high response rate compared to other similar studies. The result from this study shows that former experience from similar projects, current workload and the clients economic condition are very important factors for both whether or not the contractor will bid for a project as well as the cost estimation and tendering price. Former experience from similar projects is also an important factor for the determination of the indirect costs.

När pojkar betraktas som män : en kvantitativ och kvalitativ studie om åldersgräns för tonårspojkar på Sveriges kvinnojourer

This paper aimed to investigate to what extent there is an age cut-off for teenage boys in the women?s shelters of Sweden and how a possible cut-off is described and maintained. This occurrence has not been investigated earlier to a large extent, which emphasizes the importance of this paper. A mixed strategy was used to cover both the frequency as well as the explanations to the age cut-off. The quantitative survey was sent to all women?s shelters in Sweden and the result showed that 56 % of the shelters had an age cut-off for teenage boys from 12 years of age and above.

Läsa med självförtroende : En fallstudie om hur lärare arbetar för att motverka Matteuseffekten

The aim of the study is to investigate how a teacher and a special education teacher cooperate to prevent a pupil with reading difficulties from ending up in the vicious circle of the Matthew effect, and to find out how a pupil with reading difficulties experiences his or her reading situation. This case study is based on a phenomenological perspective whereby qualitative interviews illuminate a commonly occurring problem in today?s schools. Interviews were conducted with a teacher, a special education teacher, and a pupil in grade 1, in order to cover everyone?s perspective in this situation.

Mixtekniker

A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.

Effekt på värdeutfallet av sågad vara vid övergång från 30 till 60 cm moduler : - en fallstudie av Moelven

The purpose of this study is to explain how the value of sawn wood changes when sawn wood are cut in 30 respective 60 cm lengths. The raw material into the saw mill will mainly be bucked in 30cm and 60 cm modules. There will also be two alternatives where the timber will be bucked special lengths, 370, 490 and 550 cm but also in 490 and 550 cm.The method used for the study is to simulate both cutting and sawing the woods. For cutting the simulator Timan is used and for sawing the simulator Timberopt is used. When data is generatedfrom the simulators, calculations of some key figures is done and also how much the revenue need to be increased for the sawn wood in order to cover for the increased costs of changing sawn woodfrom 30 cm to 60 cm modulesThe conclusion is that the single biggest reason, impacting the value of the sawn wood is the cutting at the saw mill.When going from 30 to 60 cm modules, the impact will be that the customers to the saw mill must pay more to increase the revenue by at least 10% for the sawn wood in order to justifice the changein production.It is also possible to increase the value of the products further by bucking the timber in three lengths, 370, 490 and 550 cm, in order to get 12 % increase of the share of longer sawn wood (>= 480 cm)..

Modellering av diametern hos tall (Pinus sylvestris) som en effekt av beståndstäthet och biomekanik

Med gallringseffekt menas att träden efter en gallring ökar sin diametertillväxt. Denna effekt har traditionellt tillskrivits den minskade konkurrensen om ljus och näringsämnen mellan träden. En alternativ förklaring till gallringeffekten är att vindpåverkan per träd blir högre i det gallrade beståndet, vilket leder till större svajningar för träden och därmed en ökad diametertillväxt. I studien undersöktes ifall vindens påverkan är en del av gallringseffekten på tall (Pinus sylvestris L). Lokalen för studien var SLU:s försökspark i Siljansfors utanför Mora. Omgivande tätheter av stamantal, grundyta, kronvolym och kronmantelyta beräknades på flera avstånd från varje individuellt träd.

Hantering av handhållna läsenheter - en kvalitativ analys av läsbegreppet på nätforumet MobileRead

The aim of this study is to examine reading on the MobileReadforums. The term ?to read? is extended to also cover bookcollection and usage of new technology such as mobile readerunits.A catalyst for reading on mobile reader units seem to be the needto always have access to the personal e-book collection. Apartfrom being a source for reading the collection of e-books alsoserves the purpose of extending the members self-esteem.A large portion of the activities on the MobileRead forum isaimed at making new technology comprehensible with the help ofprotocols to determine the usage of that technology. The processof making protocols also seem to be another way for the membersto extend their self-esteem.Traditional libraries are mainly seen as one of many sources for ebooks.Librarians are mostly perceived as being service mindedbut lacking in e-book knowledge.There is also a risk for miscommunication as the library hasdeveloped other protocols that defines an e-book and how itshould be used.This study is a qualitative analysis based on forum posts collectedfrom the MobileRead forum..

There will primarily manure from stables that rot to biogas. The biogas plant will also have the capacity that rot others substrates that can arise in the farm operation. The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.This study has implemented multiple cases study of different investment scenarios.

Finansiella garantier - en möjlighet att säkerställa ett miljömässigt omhändertagande av uttjänta produkter

Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.
