In order to reduce its environmental impact, the chemical industry no longer produces base chemicals such as ethylene, solely from fossil, but also from biomass-based feedstocks. However, a biomass option suitable for one region might not be as suitable for another region due to, e.g., long transport and the related environmental. Therefore, local biomass alternatives and the environmental impact
We analyze the Ce3+-Pr3+:Y2SiO5 emission spectra obtained under selective excitation of the two Ce3+ sites in Y2SiO5 and we show clear evidence of direct energy transfer from Ce3+ to Pr3+. Energy transfer microparameters were calculated from the experimental spectral overlap between the Ce3+ emission and the Pr3+ and Eu3+ absorptions from which, the transfer mechanisms Ce3+-> Pr3+ are concluded to
Biological applications of ion beams have recently become a new important research field using single ion hit facilities to study individual living cells and their response to the hit of a counted number of ions. One motivation is the search for a better understanding of the fundamental processes taking place in cells and organs as a result of irradiation. Another comes from the increasing interes
This study deals with the transformation of institutions of higher technical education in Sweden. It situates those processes in the context of educational reforms during the second half of the 20th century. Lund Institute of Technology, Lunds tekniska högskola (LTH), is focused upon. It was founded in 1961 as a major addition to the expanding higher education system. As a newly established instit
During the last few years increased focus has been given to environmental and social issues due to worldwide changes in the weather and temperature, in some cases leading to natural disasters and dramatic changes in everyday life. Media and politicians have begun to address related problems, acknowledging the fact that human impact on nature is a real problem that poses as a threat to our future.
When grief finds new ways - a qualitative study about grief blogs The purpose of this study was to examine why people who suffer from grief chooses to share their experiences through blogs on the Internet. Furthermore and by studying the blogs we intended to gain understanding of the advantages and disadvantages that blogging can bring to the bloggers. The study is based on a qualitative analysis
Problem discussion: To be more competitive, Trading Area Wood is working on developing their suppliers in efficiency projects. However, they find it hard to motivate their suppliers to take part in the projects. Therefore, they need a way to show the suppliers the positive effects of participating in the efficiency projects. Moreover, Trading Area Wood has troubles to predict the economical outcom
Problem statement This master thesis was initiated since today, when developing a new mobile phone at Sony Ericsson, it is difficult to get a perception of the ergonomics and the tactility of the keyboard before the first design prototype (DP0 and DP1) is built. The SLA block model used today is completely solid and consequently a secured decision of the final design can not be made in this phase
Our master thesis is performed for Faiveley Transport AB, Landskrona. The company’s main business area is development and assembly of complete brake systems, wheels and couplings for railway vehicles. The company is currently working on a project, V-Brake, to develop a new competitive brake. Earlier two students, T. Persson and J. Mårtensson, have been working with the development of the brake, bu

RNA interference (RNAi) plays a major role in regulation of gene expression in most eukaryotic organisms. On a basic level it is a protein complex named RNA induced silencing complex (RISC) that binds a RNA strand, a micro RNA (miRNA) or a small interfering RNA (siRNA), which guides it to its intended target, an mRNA. The RISC then disrupts translation of the bound mRNA, either by restricting it t
Ett patent är en immateriell rättighet som medför en ensamrätt för patenthavaren att dra affärsmässig nytta av en viss uppfinning under en begränsad tidsperiod. Den som kränker patenthavarens ensamrätt gör sig skyldig till patentintrång. Vid patentintrång tillhandahåller den svenska patentlagen (1967:837) ett antal olika sanktionsmöjligheter. De primära civilrättsliga sanktionsformerna utgörs av pA patent is a kind of intellectual property right that grants the patent holder an exclusive right to profit from a certain invention for a limited time period. Anyone who violates the patent holder's exclusive right is guilty of patent infringement. In cases of patent infringement the Swedish Patent Act (patentlag 1967: 837) provides a number of different sanction options. The primary civil s
We have previously proposed a blind system identification method that exploits the underlying dynamics of non-Gaussian signals in [Li and Andersen, "Blind identification of Non-Gaussian Autoregressive Models for Efficient Analysis of Speech Signals," Proceedings of the International Conference on Acoustics, Speech and Signal Processing (ICASSP), May 2006, vol. 1, pp. I-1205-1-1208]. The signal mod
Popular Abstract in Swedish Villkoren för utbildning och undervisning förändras i väsentliga avseenden i takt med samhällets tilltagande komplexitet. Det är många gånger svårt för både lärare och elever att veta hur man på bästa sätt ska orientera sitt pedagogiska handlande. Med utgångspunkt från tre pedagogiska kontexter - grundskolan, de särskilda ungdomshemmen och grundskollärarutbildningen - pPedagogical practice is, in several important considerations, contradictory in character. In this dissertation attenention is drawn towards the field of tension that prevails between pedagogical action, which can be descibed in terms of strategic processes and communicative pedagogical action. While the former places the preconditions for effective knowledge development of the individual at the ce
Popular Abstract in Swedish I »operatörens blick« beskrivs ett projekt där möjligheter för IT-stöd i erfarenhetsöverföring undersökts inom ett område där konfrontationen mellan datorisering och yrkeskunnande är särskilt tydlig - operatörsarbete i processindustrin. Driftsstörningar av olika omfattning är ett kontinuerligt inslag i operatörsarbetet och snabba förändringar i risknivå är en central deStudies in process control automation show that manual control skills are important in handling situations where the automatic control system fails. The fact that these skills are particularly difficult to maintain and develop in automated production environments is usually described as one of the ironies of automation. This work explores new roles for computer support in developing and maintainin
Continuous production control is important for the production using Tetra Pak equipment, as problems that are found early in the chain of production can minimize the need for waste greatly. In production of paper straws, a possible production control could be to photograph straws during production, analyse these and predict how good the straw is, using the image. If the predicted performance of th
I denna uppsats utreder jag vilken rätt gifta barn har att återförenas med sina föräldrar eller med sin make eller maka. Detta för att ur ett barnrättsperspektiv utreda om ett ingånget barnäktenskap begränsar barns rätt till familjeåterförening. Syftet är även att undersöka på vilket sätt principen om barnets bästa förhåller sig till gifta barns rätt till familjeåterförening, för att sedan utreda From a child’s rights perspective this essay seeks to investigate whether child marriage restricts children’s right to family reunification. In this essay I therefor study what rights married children have to reunite with their parents or with their spouse. The purpose of this essay is also to investigate how the principle of the best interest of the child relates to married children’s right to fa
