Coal desulfurization by chlorinolysis production and combustion test evaluation of product coals

Laboratory-scale screening tests were carried out on coal from Harrison County, Ohio to establish chlorination and hydrodesulfurization conditions for the batch reactor production of chlorinolysis and chlorinolysis-hydrodesulfurized coals. In addition, three bituminous coals, were treated on the lab scale by the chlorinolysis process to provide 39 to 62% desulfurization. Two bituminous coals and one subbituminous coal were then produced in 11 to 15 pound lots as chlorinolysis and hydrodesulfurized coals. The chlorinolysis coals had a desulfurization of 29-69%, reductions in voltatiles and hydrogen. Hydrodesulfurization provided a much greater desulfurization (56-86%), reductions in volatiles and hydrogen. The three coals were combustion tested in the Penn State ""plane flame furnace'' to determine ignition and burning characteristics. All three coals burned well to completion as: raw coals, chlorinolysis processed coals, and hydrodesulfurized coals. The hydrodesulfurized coals experienced greater ignition delays and reduced burning rates than the other coals because of the reduced volatile content. It is thought that the increased open pore volume in the desulfurized-devolatilized coals compensates in part for the decreased volatiles effect on ignition and burning

Mobile integrated conditional access system

This paper presents design of a novel security architecture integrating mobile and broadcasting technologies in the Pay-TV system. The security architecture proposed herein is a state-of-the-art solution to tackle well-known problems challenging current Pay-TV systems including but not limited to interoperability amongst service providers, relatively high cost of the service deployment, the security compromise, limited interactivity and bespoken services offered to subscribers. It also proposes the Follow-me service that enables subscribers to access their entitlements via an arbitrary set-top box

Security architectures in mobile integrated pay-TV

This paper presents the design and describes the advantage of the state-of-the-art Mobile Integrated Conditional Access System (MICAS) concerning interoperability, personalisation, security and operational costs in Pay-TV systems. The Message Handling Subsystem is proposed and outlined together with ‘Follow-Me’ service, which proposed herewith to extend mobility and personalisation concepts on Pay-TV service

When Both Transmitting and Receiving Energies Matter: An Application of Network Coding in Wireless Body Area Networks

A network coding scheme for practical implementations of wireless body area networks is presented, with the objective of providing reliability under low-energy constraints. We propose a simple network layer protocol for star networks, adapting redundancy based on both transmission and reception energies for data and control packets, as well as channel conditions. Our numerical results show that even for small networks, the amount of energy reduction achievable can range from 29% to 87%, as the receiving energy per control packet increases from equal to much larger than the transmitting energy per data packet. The achievable gains increase as a) more nodes are added to the network, and/or b) the channels seen by different sensor nodes become more asymmetric.Comment: 10 pages, 7 figures, submitted to the NC-Pro Workshop at IFIP Networking Conference 2011, and to appear in the conference proceedings, published by Springer-Verlag, in the Lecture Notes in Computer Science (LNCS) serie

Candido Portinari: Brazilian Artist as Cultural Ambassador: A Re-Examination of the Library of Congress Murals

The artistic contributions of Portinari, and of many other Brazilian and Latin American modern artists, have not been adequately examined as part of the visual history of the twentieth century. Although by no means comprehensive, this study employs an holistic approach to re-examining Portinari\u27s Library of Congress murals in an attempt to understand better not only these distinctive murals, but also the historical significance of this twentieth century artist

Challenges in imaging and predictive modeling of rhizosphere processes

Background Plant-soil interaction is central to human food production and ecosystem function. Thus, it is essential to not only understand, but also to develop predictive mathematical models which can be used to assess how climate and soil management practices will affect these interactions. Scope In this paper we review the current developments in structural and chemical imaging of rhizosphere processes within the context of multiscale mathematical image based modeling. We outline areas that need more research and areas which would benefit from more detailed understanding. Conclusions We conclude that the combination of structural and chemical imaging with modeling is an incredibly powerful tool which is fundamental for understanding how plant roots interact with soil. We emphasize the need for more researchers to be attracted to this area that is so fertile for future discoveries. Finally, model building must go hand in hand with experiments. In particular, there is a real need to integrate rhizosphere structural and chemical imaging with modeling for better understanding of the rhizosphere processes leading to models which explicitly account for pore scale processes

Neural and physiological data from participants listening to affective music

Music provides a means of communicating affective meaning. However, the neurological mechanisms by which music induces affect are not fully understood. Our project sought to investigate this through a series of experiments into how humans react to affective musical stimuli and how physiological and neurological signals recorded from those participants change in accordance with self-reported changes in affect. In this paper, the datasets recorded over the course of this project are presented, including details of the musical stimuli, participant reports of their felt changes in affective states as they listened to the music, and concomitant recordings of physiological and neurological activity. We also include non-identifying meta data on our participant populations for purposes of further exploratory analysis. This data provides a large and valuable novel resource for researchers investigating emotion, music, and how they affect our neural and physiological activity

Youth social exclusion in Australian communities: a new index

Using specialised data from the 2011 Census, this paper presents a new index intended to be representative of youth at risk of social exclusion. Abstract Social exclusion and inclusion has been given a great deal of attention in Australia and throughout the world. This broader concept of disadvantage has replaced much of the social discourse around poverty and inequality, with the realisation from researchers, practitioners and policy makers that disadvantage is often a multi-dimensional occurrence, spanning many dimensions of an individual’s life. Despite the attention social exclusion has been given, particular population groups are often overlooked – particularly young people. A growing interest in the power of geographic data and the prevalence of social exclusion, has lead the authors to develop the first nation-wide geographically disaggregated index of youth social exclusion for Australia. A number of domains and indicators deemed important to youth wellbeing were identified and constructed to develop a comprehensive index of youth social exclusion for young people aged 15-19 years. Using specialised data from the 2011 Census, supplemented with national school assessment data, we use a domains approach to construct an index that is representative of youth at risk of social exclusion, using a combination of principal components and equal weighting techniques. Particular attention is paid to ‘youth’ as an important stage of life in its own right and the implications of the delayed transition into adulthood that is now seen in many developed nations. Many more young people now remain as dependent children well into their twenties. A final index of youth social exclusion across Australian communities is presented and discussed
