Engineered Structured Sorbents for the Adsorption of Carbon Dioxide and Water Vapor from Manned Spacecraft Atmospheres: Applications and Modeling 2007/2008

In NASA s Vision for Space Exploration, humans will once again travel beyond the confines of earth s gravity, this time to remain there for extended periods. These forays will place unprecedented demands on launch systems. They must not only blast out of earth s gravity well as during the Apollo moon missions, but also launch the supplies needed to sustain a larger crew over much longer periods. Thus all spacecraft systems, including those for the separation of metabolic carbon dioxide and water from a crewed vehicle, must be minimized with respect to mass, power, and volume. Emphasis is also placed on system robustness both to minimize replacement parts and ensure crew safety when a quick return to earth is not possible. This paper describes efforts to improve on typical packed beds of sorbent pellets by making use of structured sorbents and alternate bed configurations to improve system efficiency and reliability. The development efforts described offer a complimentary approach combining testing of subscale systems and multiphysics computer simulations to characterize the regenerative heating substrates and evaluation of engineered structured sorbent geometries. Mass transfer, heat transfer, and fluid dynamics are included in the transient simulations

Can surveying practitioners about their practices help identify priority clinical practice guideline topics?

BACKGROUND: Clinical practice guidelines are systematically developed statements designed to assist in patient and physician clinical decision making for specific clinical circumstances. In order to establish which guideline topics are priorities, practitioners were surveyed regarding their current practice. METHODS: One hundred ninety-seven practitioners in Ontario, Canada were mailed a survey exploring their current practice or opinion regarding the prophylactic use of anticonvulsant drugs in patients with malignant glioma who had never had a seizure. The survey consisted of seven questions regarding the relevance of a guideline on the subject to the practitioner's practice, the proportion of clinical cases involving anticonvulsant use, knowledge of existing guidelines on this topic, interest in reviewing a completed practice guideline and three clinical scenarios. RESULTS: There were 122 respondents who returned the survey (62% rate of return). Eighty percent of the practitioners who responded indicated that less than 25% of their clinical cases involved the use of anticonvulsants; however, only 16% of respondents indicated that a practice guideline would be irrelevant to their practice. Eighty percent of respondents volunteered to review a draft version of a practice guideline on the use of anticonvulsants. The survey presented the practitioners with three scenarios where anticonvulsants in patients with brain tumours may be appropriate: peri-operatively in patients without seizures, postoperatively in patients currently using anticonvulsants, and thirdly in patients not currently using anticonvulsants or undergoing surgery. In contrast to the third situation, the first two situations yielded considerable variation in practitioner response. CONCLUSION: The survey established that there is some variation present in the current practice of anticonvulsant use in the patients with brain tumours. Whether there is an optimal treatment practice has yet to be determined. Practitioners do seem to feel that a guideline on anticonvulsant use in warranted, and most practitioners would be interested in being part of the guideline development process

Thinking aloud: an exploration of cognitions in professional snooker

Objectives: Presently, there is no exploration into the cognitive processes of super-elite and elite professional snooker players during real-time performance. Therefore, this study explored the cognitions of seven professional snooker players during real-time solo practice performance. Design: A Think Aloud (TA) protocol analysis. Method: This involved players verbalizing and explaining their thoughts within naturalistic practice environments. Player’s verbalizations were recorded during each solo practice performance, transcribed verbatim, and analyzed via protocol analysis. Results: Analyses revealed an array of continuous reactive-adaptive cognitions relat-ing to stressors and coping strategies during performance, as well as general snooker-specific related thoughts. Specifically, the results highlighted key stressor themes which were coded as: Table Conditions, Distractions, and Mistakes. Our main finding was: Shot Preparation being essential to problem-focused coping, with Rationalizing integral to emotion-focused coping. Further results highlighted the visualperceptual and cognitive expertise of players, with regards to identification of problem balls and cueball spatial awareness, insofar as unearthing the delib-erate structure to practice routines. Conclusions: The study’s original and novel findings lend further support to the transactional process of coping. Whilst accordingly, the utilization of TA significantly contributed to our limited understanding of super-elite and elite real-time cogni-tions in professional snooker and self-paced sports generally. Future research should continue to dissect the sport-specific nuances that underpin real-time performance, not only during prac-tices, but within competitive play. TA is an appropriate methodology to use in the domain-specific sport of snooker

The Mason-Alberta Phonetic Segmenter: A forced alignment system based on deep neural networks and interpolation

Forced alignment systems automatically determine boundaries between segments in speech data, given an orthographic transcription. These tools are commonplace in phonetics to facilitate the use of speech data that would be infeasible to manually transcribe and segment. In the present paper, we describe a new neural network-based forced alignment system, the Mason-Alberta Phonetic Segmenter (MAPS). The MAPS aligner serves as a testbed for two possible improvements we pursue for forced alignment systems. The first is treating the acoustic model in a forced aligner as a tagging task, rather than a classification task, motivated by the common understanding that segments in speech are not truly discrete and commonly overlap. The second is an interpolation technique to allow boundaries more precise than the common 10 ms limit in modern forced alignment systems. We compare configurations of our system to a state-of-the-art system, the Montreal Forced Aligner. The tagging approach did not generally yield improved results over the Montreal Forced Aligner. However, a system with the interpolation technique had a 27.92% increase relative to the Montreal Forced Aligner in the amount of boundaries within 10 ms of the target on the test set. We also reflect on the task and training process for acoustic modeling in forced alignment, highlighting how the output targets for these models do not match phoneticians' conception of similarity between phones and that reconciliation of this tension may require rethinking the task and output targets or how speech itself should be segmented.Comment: submitted for publicatio

ANTIGEN-SPECIFIC SYNERGISM IN THE IMMUNE RESPONSE OF IRRADIATED MICE GIVEN MARROW CELLS AND PERITONEAL CAVITY CELLS OR EXTRACTS

A synergistic immune response to foreign erythrocytes may be induced in heavily irradiated mice injected with a mixture of isologous cells obtained from marrow and from the peritoneal cavity. Under appropriate conditions, homologous or heterologous peritoneal cavity cells, heat-killed cells, or cellfree extracts made from such cells are also effective. The activity of the peritoneal cavity cells or extracts is antigen-specific, in the sense that cells or extracts obtained from animals previously immunized with the test antigen produce much stronger synergistic effects than do cells from animals immunized with some other antigen; however, the peritoneal cavity cells or extracts are not immunogenic when tested in primed animals. The marrow cells, demonstrated to contain precursors of the antibody-forming cells produced during this synergistic immune response, also show a form of antigen-specificity

Combination of carbon nanotubes and two-photon absorbers for broadband optical limiting

New systems are required for optical limiting against broadband laser pulses. We demonstrate that the association of non-linear scattering from single-wall carbon nanotubes (SWNT) and multiphoton absorption (MPA) from organic chromophores is a promising approach to extend performances of optical limiters over broad spectral and temporal ranges. Such composites display high linear transmission and good neutral colorimetry and are particularly efficient in the nanosecond regime due to cumulative effects.Comment: 5 avril 200

Perception of Unfamiliar English Phonemes by Native Mandarin Speakers

In second language acquisition, speech sounds, or phonemes, not present in a learner’s native language often pose an extra challenge for speech production. When hearing one of these unfamiliar phonemes, the learner either maps it to a similar native phoneme, perceives it as a completely foreign sound, or does not perceive it as speech at all. In the first case, the learner is unable to perceive a difference between the unfamiliar phoneme and the native phoneme to which it is mapped. This mapping difficulty potentially creates problems for the learner during word recognition. The present research investigated the extent to which English phonemes absent from the Mandarin phonological inventory impact processing of native Mandarin speakers in an auditory lexical decision task. Results of this research will expand the understanding of second language perception, especially within the context of auditory lexical decision tasks. A list of ten phonemes—/ɪ/, /æ/, /ʊ/, /ɛ/, /v/, /z/, /ʒ/, /ɵ/, /ð/, /ʤ/—present in the English phonological inventory but absent from that of Mandarin were identified as unfamiliar to native Mandarin speakers. Data from the Massive Auditory Lexical Decision (MALD) database, in which participants decided whether recorded utterances were English words or made-up words, were utilized. The effects of the proportion of unfamiliar phonemes, proportion of unfamiliar vowels, and proportion of unfamiliar consonants on reaction time, representative of processing difficulty, were then calculated using statistical techniques. It was found that the proportion of all unfamiliar phonemes in an utterance had no significant effect on the reaction time of the native Mandarin speakers. However, when the list of unfamiliar phonemes was divided into vowels and consonants, a greater proportion of unfamiliar vowels was noticed to increase reaction time, while a greater proportion of unfamiliar consonants was found to decrease reaction time. Further research in this area is required to determine a concrete explanation for these results. Interestingly, when the same analysis was performed on the data of native English speakers, similar results were observed. This may reflect a common language processing mechanism in second language learners and native speakers
