Schaeffer est mort! Long live Schaeffer!
No full textThis paper examines two groups of composers and discusses the commonality in their approach to using concrete sound materials and rhythm in their works. As a result of this commonality an examination of the ways in which these composers have expanded the electroacoustic language through the hybridisation of electronica and musique concrete techniques is undertaken. It will then be demonstrated how these works, whilst pushing at the boundaries of electroacoustic music can nevertheless be discussed and analysed with reference to Emmerson’s language grid as originally proposed in The Relation of Language to Materials (1986: 17-39). It will be demonstrated how, with the advent of the sampler and proliferation of works utilizing concrete materials, Emmerson’s language grid can be used as the basis for a wider discussion of electronic works

Dr. Daniels is highly regarded as one of the leading scholar activists of his era. Richard Adams has served for several decades as a community organizer and activist. He has worked with many local grassroots group to address problematic conditions. With their wide experiences and keen insights Daniels and Adams address a wide array of concerns about ways and means for enhancing cooperative efforts among progressive groups, the prospects for Pan-Africanism in the 21st century, and building responsible leadership that will push to empower Black communities
Swarming and complex pattern formation in <it>Paenibacillus vortex </it>studied by imaging and tracking cells
No full textAbstract Background Swarming motility allows microorganisms to move rapidly over surfaces. The Gram-positive bacterium Paenibacillus vortex exhibits advanced cooperative motility on agar plates resulting in intricate colonial patterns with geometries that are highly sensitive to the environment. The cellular mechanisms that underpin the complex multicellular organization of such a simple organism are not well understood. Results Swarming by P. vortex was studied by real-time light microscopy, by in situ scanning electron microscopy and by tracking the spread of antibiotic-resistant cells within antibiotic-sensitive colonies. When swarming, P. vortex was found to be peritrichously flagellated. Swarming by the curved cells of P. vortex occurred on an extremely wide range of media and agar concentrations (0.3 to 2.2% w/v). At high agar concentrations (> 1% w/v) rotating colonies formed that could be detached from the main mass of cells by withdrawal of cells into the latter. On lower percentage agars, cells moved in an extended network composed of interconnected "snakes" with short-term collision avoidance and sensitivity to extracts from swarming cells. P. vortex formed single Petri dish-wide "supercolonies" with a colony-wide exchange of motile cells. Swarming cells were coupled by rapidly forming, reversible and non-rigid connections to form a loose raft, apparently connected via flagella. Inhibitors of swarming (p-Nitrophenylglycerol and Congo Red) were identified. Mitomycin C was used to trigger filamentation without inhibiting growth or swarming; this facilitated dissection of the detail of swarming. Mitomycin C treatment resulted in malcoordinated swarming and abortive side branch formation and a strong tendency by a subpopulation of the cells to form minimal rotating aggregates of only a few cells. Conclusion P. vortex creates complex macroscopic colonies within which there is considerable reflux and movement and interaction of cells. Cell shape, flagellation, the aversion of cell masses to fuse and temporary connections between proximate cells to form rafts were all features of the swarming and rotation of cell aggregates. Vigorous vortex formation was social, i.e. required > 1 cell. This is the first detailed examination of the swarming behaviour of this bacterium at the cellular level.</p

Sports Fans' Evaluations of Sporting Code Innovations
No full textToday's professional sports are frequently evolving and changing their design, structure and format. Many such innovations have been spurred on by the opportunity to capitalise financially on new markets and increase profit. This study used both quantitative (survey) and qualitative (depth interviews) methods in order to examine fans' attitudes towards the current state of Rugby Union, Rugby League, Netball, Soccer and Cricket. The findings for Rugby Union concluded that the recent experimental law variations have succeeded in what they were introduced to do. Fans believe that Rugby is more exciting to watch than ever before and that it is now a faster and more attack-focused contest. Fans believe that Rugby League has improved following the introduction of the video referee and in particular by the use of two on-field referees. They believe that it is now a more exciting and faster game. Fans also believe that salary caps are good for Rugby League and help to increase competition and spread the wealth of talent among the teams. Netball fans are excited by possible new innovations and show support for the inclusion of power plays, two point goals, rolling substitutions and increased physical contact. Fans believe that Soccer needs to adopt technology in order to help its officials but they also admire the traditionalism of the code. Surprisingly, fans show support for increasing the sizes of Soccer‟s goals in order to make it easier for teams to score. Fans show support for Twenty20 cricket and seem undeterred by recent match fixing scandals. There is also evident support for the introduction of Beach Cricket to New Zealand. Analysing fans' attitudes towards professional sport's product innovations has led to a final implication and conclusion for the administrators and governing bodies of professional sport. That is, it would be wise to keep the traditional codes and their formats as traditional as possible. However, evolve the same sport in to a completely separate format in order to financially capitalise on different markets. Twenty20 cricket is a perfect example of this
CO2 capture through electrified calcination in cement clinker production
No full textThe cement industry has the second highest share of industrial CO2 emissions, and two-thirds of these emissions come from decomposing its key ingredient by the calcination reaction (CaCO3 → CaO + CO2). This thesis studied the electrification of the calcination process. Electrified calcination will produce a relatively pure CO2 stream, which can be sent for direct utilization/storage, thereby avoiding a separate CO2 capture plant.
The main aim of the work is to recommend a suitable design for an electrified calciner heated by resistance heating technology. The main aim is achieved by answering four key questions related to 1) impacts on the mass and energy balance, 2) technical feasibility, 3) heat transfer efficiency, and 4) design recommendations. The key questions are answered by performing a mass and energy balance using Aspen Plus, experimental studies of different calciner designs, 1-D and transient modelling of different calciner designs, and computational particle fluid dynamics (CPFD) simulations of a fluidized bed calciner design.
The mass and energy balance results show that the CO2 emissions can be reduced up to 78% by using an electrified calciner instead of a coal-fired calciner. Moreover, a hybrid system integrating an electrified calciner with an amine-based CO2 capture unit using only internal heat integration can completely decarbonize the cement industry (i.e., close to 100% reduction). Different calciner concepts require different levels of CO2 recycling in the calciner. Increased gas recycling increases the calciner energy demand as the recycling gas must be heated. The energy demand can be reduced with heat recovery from the recycling gas. Such heat recovery is especially relevant for high and extremely high gas recycling cases. Moreover, CO2 capture from an electrified calciner is better than from a pure amine-based capture system as it requires lower input of extra energy.
The entrained flow calciner requires more than 2000 heating rods working under high gas velocities, so this design is unlikely to be technically feasible. The rotary calciner designs are technically feasible but have scale-up problems.
The fluidized bed calciner operating with a binary particle mixture is in interesting concept. Fine raw meal particles are difficult to fluidize, but cold-flow experiments have demonstrated that a mixture of raw meal and coarse inert particles can be fluidized, and subsequently segregated. A design of such a calciner also seems promising at hot flow conditions, based on results from CPFD simulations. However, the fluidized bed design should be experimentally validated also at hot flow conditions.
The fluidized bed calciner has the highest heat transfer efficiency and the lowest surface heat loss as it has a high heat transfer coefficient and high heat transfer area per internal surface area of the calciner geometry.
To conclude, the fluidized bed calciner is recommended as it has the highest heat transfer efficiency, and the concept seems promising both from cold flow tests and from CPFD simulations. An electrified fluidized bed calciner design is proposed, and this can be experimentally tested in future work.publishedVersio
