Resa diagnostica di anamnesi, EEG intercritico ed home-made video negli episodi parossistici notturni: confronto con la VEPSG

Poiché la diagnosi differenziale degli episodi parossistici notturni è affidata alla VEPSG, tenendo conto dei limiti di tale metodica, il progetto attuale ha lo scopo di definire la resa diagnostica di strumenti alternativi alla VEPSG: anamnesi, home-made video ed EEG intercritico. Sono stati reclutati consecutivamente 13 pazienti, afferiti al nostro Dipartimento per episodi parossistici notturni. Ciascun paziente è stato sottoposto ad un protocollo diagnostico standardizzato. A 5 Medici Esperti in Epilessia e Medicina del Sonno è stato chiesto di formulare un orientamento diagnostico sulla base di anamnesi, EEG intercritico, home-made video e VEPSG. Attraverso l’elaborazione degli orientamenti diagnostici è stata calcolata la resa diagnostica delle procedure esaminate, a confronto con la VEPSG, attraverso il concetto di “accuratezza diagnostica”. Per 6 pazienti è stato possibile porre una diagnosi di Epilessia Frontale Notturna, per 2 di parasonnia, in 5 la diagnosi è rimasta dubbia. L’accuratezza diagnostica di ciascuna procedura è risultata moderata, con lievi differenze tra le diverse procedure (61.5% anamnesi; 66% home-made video; 69,2 % EEG intercritico). E’ essenziale migliorare ulteriormente l’accuratezza diagnostica di anamnesi, EEG intercritico ed home-made video, che possono risultare cruciali nei casi in cui la diagnosi non è certa o quando la VEPSG non è disponibile.

The Mechanisms of wear of the video head

      This thesis examines the mechanism of wear occuring to the video head and their effect on signal reproduction. in particular it examines the wear occuring to manganese-zinc ferrite heads in sliding contact with iron oxide media.       A literature survey is presented, which covers magnetic recording technologies, focussing on video recording. Existing work on wear of magnetic heads is also examined, and gaps in the theoretical account of wear mechanisms presented in the literature are identified.       Pilot research was carrried out on the signal degradation and wear associated witha number of commercial video tapes, containing a range of head cleaning agents. From this research, the main body of the research was identified. A number of methods of wear measurement were examined for use in this project. Knoop diamond indentation was chosen because experimentation showed it to be capable of measuring wear occuring in situ. This technique was then used to examine the wear associated with different levels of A12O3 and Cr2O3 head cleaning agents.      The results of the research indicated that, whilst wear of the video head increases linearly with increasing HCA content, signal degradation does not vary significantly. The most significant differences in wear and signal reproduction were observed between the two HCAs. The signal degradation of heads worn with tape samples containing A12O3 HCA was found to be lower than heads worn with tapes containing Cr2O3 HCA.      The results also indicate that the wear to the head is an abrasive process characterised by ploughing of the ferrite surface and chipping of the edges of the head gap. Both phenomena appear to be caused by poor iron oxide and head cleaning particles, which create isolated asperities on the tape surface.   

Desenho de deficiência visual: uma experiência no ensino de artes visuais na perspectiva da educação inclusiva

Over the past 30 years, Art Education in interface with disabilities has been a subject of increasing interest in research in academia, especially with regard to Special Education, but still has some shortages in terms of socialization studies to discuss this type of teaching from the perspective of inclusive education. In this scenario, this paper presents an analysis from the field of teaching Visual Arts in the context of school inclusion, with emphasis on teaching drawing to the visually impaired. The conducted literature indicates a number of authors who discuss teaching drawing to people with visual disabilities, who are dedicated primarily to the Special Education context. In this sense, the shortage of research that discuss this teaching from the perspective of inclusive education, this research aimed at the inclusive approach to teaching drawing in the school context. Thus, the aim of this study was to develop a proposal for a pedagogical intervention in Visual Arts, with reference to drawing and its construction process, with the participation of seeing and unseeing students. Therefore, the methodological approach, which was qualitative, was the intervention research, in the light of the Bakhtinian principles of dialogism and otherness, with exploratory study characteristics. The locus of the research was the State School Admiral Newton Braga Faria, which is located in Alecrim, on the East Zone of Natal / RN and is near the Institute for Education and Rehabilitation of the Blind - IERC / RN. The class chosen for intervention was the 7th grade “C” afternoon shift, which had children aged 12 to 16, with 27 students enrolled, three students with disabilities: 02 blind girls and 01 deafblind boy with light hearing and visual loss. As interlocutors of the research, we could also count on the Art teacher who served as a collaborator, as well as teacher in the school’s Multifunction Resource Room. The instruments and research procedures were observation, semi-structured interview, field diary and the photo / video recording. In the development of research, we conducted 10 workshops with multisensory teaching sequences, articulating the physical, tactile and graphical expressions as intrinsic to the reading and production of drawing for both seeing and unseeing students. The process and data built on research allowed for a reflection on cultural experiences with drawing in the school context and on the interactions between seeing and unseeing students in the production and analysis of tactile-visual drawings. They also point out the construction of a teaching approach to drawing, in the context of the common class, from educational workshops that enable artistic and aesthetic interactions from the perspective of school inclusiveness. Thus, we argued that the mobilization of the tactile, physical and graphical expressions can be adopted in a multisensory approach that enables a pedagogical focus that involves all students and is not restricted to the presence of students with visual impairment.

Autoscopia: um procedimento de pesquisa e de formação

This article considers a procedure for data collection called autoscopy. Autoscopy entails the video recording of a practice with the purpose of allowing analysis and self-evaluation by one of the protagonists of that practice. The objective of the video recording is that of apprehending the actions of the agent (or agents), the scenario, and the plot that make up a situation. The recorded material is subjected to sessions of analysis after the action that aim at the understanding of the reflective process of the agent (or agents) through their verbalizations during the analysis of video recorded scenes. The present text introduces a theoretical basis for the procedure of autoscopy, deals with advantages and limitations of its use, as well as with aspects that deserve attention and, finally, describes the authors' experiences in two studies in which the procedure was employed. Starting from these two experiences, differences and similarities are pointed out between the studies, especially regarding the participants, object, and the time distribution of the video recordings. The authors draw considerations about the formative-reflective potential of the procedure, both for research situations and for the learning and training of various professionals, considering it to be an excellent educational instrument. It is, however, vital to keep in mind the need to recognize and return to the teacher, as an autoscopic participant, his condition as subject of his own profession, thereby promoting, besides the self-evaluation, also the autonomy of his thinking and doing.

Slip ratio in dispersed viscous oil-water pipe flow

In this article, dispersed flow of viscous oil and water is investigated. The experimental work was performed in a 26.2-mm-i.d. 12-m-long horizontal glass pipe using water and oil (viscosity of 100 mPa s and density of 860 kg/m(3)) as test fluids. High-speed video recording and a new wire-mesh sensor based on capacitance (permittivity) measurements were used to characterize the flow. Furthermore, holdup data were obtained using quick-closing-valves technique (QCV). An interesting finding was the oil-water slip ratio greater than one for dispersed flow at high Reynolds number. Chordal phase fraction distribution diagrams and images of the holdup distribution over the pipe cross-section obtained via wire-mesh sensor indicated a significant amount of water near to the pipe wall for the three different dispersed flow patterns identified in this study: oil-in-water homogeneous dispersion (o/w H), oil-in-water non-homogeneous dispersion (o/w NH) and Dual continuous (Do/w & Dw/o). The phase slip might be explained by the existence of a water film surrounding the homogeneous mixture of oil-in-water in a hidrofilic-oilfobic pipe. (C) 2010 Elsevier Inc. All rights reserved.

Rapid increases in cytokinin concentration in lateral buds of chickpea (Cicer arietinum L) during release of apical dominance

We examined the role of cytokinins (CKs) in release of apical dominance in lateral buds of chickpea (Cicer arietinum L.). Shoot decapitation or application of CKs (benzyladenine, zeatin or dihydrozeatin) stimulated rapid bud growth. Time-lapse video recording revealed growth initiation within 2 h of application of 200 pmol benzyladenine or within 3 h of decapitation. Endogenous CK content in buds changed little in the first 2 h after shoot decapitation, but significantly increased by 6 h, somewhat later than the initiation of bud growth. The main elevated CK was zeatin riboside, whose content per bud increased 7-fold by 6 h and 25-fold by 24 h. Lesser changes were found in amounts of zeatin and isopentenyl adenine CKs. We have yet to distinguish whether these CKs are imported from the roots via the xylem stream or are synthesised in situ in the buds, but CKs may be part of an endogenous signal involved in lateral bud growth stimulation following shoot decapitation. To our knowledge, this is the first detailed report of CK levels in buds themselves during release of apical dominance.

Temperature safety profile of laparoscopic devices: Harmonic ACE (ACE), Ligasure V (LV), and plasma trisector (PT)

Background Reports of iatrogenic thermal injuries during laparoscopic surgery using new generation vessel-sealing devices, as well as anecdotal reports of hand burn injuries during hand-assisted surgeries, have evoked questions about the temperature safety profile and the cooling properties of these instruments. Methods This study involved video recording of temperatures generated by different instruments (Harmonic ACE [ACE], Ligasure V [LV], and plasma trisector [PT]) applied according the manufacturers` pre-set settings (ACE setting 3; LV 3 bars, and the PT TR2 50W). The video camera used was the infrared Flex Cam Pro directed to three different types of swine tissue: (1) peritoneum (P), (2) mesenteric vessels (MV), and (3) liver (L). Activation and cooling temperature and time were measured for each instrument. Results The ACE device produced the highest temperatures (195.9 degrees +/- 14.5 degrees C) when applied against the peritoneum, and they were significantly higher than the other instruments (LV = 96.4 degrees +/- 4.1 degrees C, and PT = 87 degrees +/- 2.2 degrees C). The LV and PT consistently yielded temperatures that were < 100 degrees C independent of type of tissue or ""on""/ ""off"" mode. Conversely, the ACE reached temperatures higher than 200 degrees C, with a surprising surge after the instrument was deactivated. Moreover, temperatures were lower when the ACE was applied against thicker tissue (liver). The LV and PT cooling times were virtually equivalent, but the ACE required almost twice as long to cool. Conclusions The ACE increased the peak temperature after deactivation when applied against thick tissue (liver), and the other instruments inconsistently increased peak temperatures after they were turned off, requiring few seconds to cool down. Moreover, the ACE generated very high temperatures (234.5 degrees C) that could harm adjacent tissue or the surgeon`s hand on contact immediately after deactivation. With judicious use, burn injury from these instruments can be prevented during laparoscopic procedures. Because of the high temperatures generated by the ACE device, particular care should be taken when it is used during laparoscopy.

Play Preferences and Behavior of Preschool Children with Autistic Spectrum Disorder in the Clinical Environment

The play of children with autistic spectrum disorder (ASD) is a valuable medium for assessment and intervention, and its analysis has the potential to aid diagnosis. This study investigated spontaneous play behavior and play object preferences for 24 preschool children with ASD in a typical occupational therapy clinical environment. Play behavior was rated and choice of play object noted at 10-second intervals from a 15-minute video recording of unstructured play. Statistical analyses indicated that play behavior was consistent with descriptions in the literature. In addition, the children demonstrated clear preferences for play objects in the form of popular characters (e.g., Thomas the Tank Engine) and those with sensorimotor properties. We propose that the inclusion of preferred play objects in a clinical environment may increase intrinsic motivation to play, and thereby enhance assessment and intervention.
