Abstract: background: bone conduction auditory brainstem responses (abr) in normal hearing individuals. aim: to evaluate the clinical applicability of bone conduction abr, characterizing normality and determining an assessment protocol. method: participants of this study were 22 individuals with normal hearing (20db na), with ages between 20 and 30 years, 14 female and 8 male. all individuals were assessed using air and bone (vibrator positioned on the forehead and mastoid) conduction abr. ep25 equipment, interacoustic; 3a insertion phone; b-71 bone vibrator; click stimulus. results: it was possible to evaluate the bone conduction abr in all individuals. the results demonstrate that the electrophysiological threshold obtained when the vibrator was positioned on the forehead (32.69 ± 5.63 and 32.5 ± 7.07db nhl) was higher than that obtained when the vibrator was positioned on the mastoid (25.00 ± 7.33 and 30.00 ± 5.34db nhl) for both genders respectively. for this reason the vibrator was positioned on the mastoid. the electrophysiological threshold obtained by bone conduction was higher than that obtained by air conduction for both genders and also when all individuals were grouped together. thus it is necessary to use a correction factor, according to the results, of 10db nhl. the latency-intensity values of the v wave in the ipsilateral and contralateral recordings differed statistically according to gender, and should be considered separately. the value of 26.81 ± 6.99db nhl was adopted as being the normal threshold for bone conduction abr. conclusion: it is possible to evaluate bone conduction abr in the clinical environment. these results, when considered along with the air conduction abr, increase the chances of a more precise diagnosis regarding the type of hearing loss.

Abstract: thanks to the care of the architect tommaso gaudencio bezzi (1844-1915) in filing documents and countless newspaper articles related to the matters that involved himself directly and the monument to brazil's independence, it was possible for us to rescue relevant facts to the understanding of the monument-building conceived by him. many descriptions of that time enable us to have visions as much of the power of representation of the work and its repercussions on the city s?o paulo's society as in the work and activities of the architect. in this sense the text reproduces articles published in s?o paulo and rio de janeiro's main newspapers in the end of the second half of the 19th century. the articles describe the work in that historical moment and valorize the architect's activity, reminding us of the importance and complexity of architecture as an artistic production. "[…] the foundations and the ground floor have are already built. the brick of homogen contexture and great hardness is handmade, making on it, as if it was to be uncovered, all the moldings with a perfection whose secret only the italian workers have. hundreds of workers are in the labor, a number that should increase later when the distribution of work allows for that. an inclined plan, of great extension and powered by steam, takes the material to the top of the hill. it is expected that the sculptor bernadelli is the responsible for moulding the statue of d. pedro i and the others that shall decorate the building, which should, in a short time, be appreciated by the model in relief, which is carefully making mr. bezzi."

Nanopores Structure in Electrospun Bacterial Cellulose  [PDF]
Ligia Maria Manzine Costa, Gabriel Molina de Olyveira, Pierre Basmaji, Lauro Xavier Filho
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2012, DOI: 10.4236/jbnb.2012.31012
Abstract: Bacterial cellulose (BC) has established to be a remarkably versatile biomaterial and can be used in wide variety of applied scientific endeavours, especially for medical devices, lately, bacterial cellulose mats are used in the treatment of skin conditions such as burns and ulcers, because of the morphology of fibrous biopolymers serving as a support for cell proliferation, its pores allow gas exchange between the organism and the environment. Moreover, the nanostructure and morphological similarities with collagen make BC attractive for cell immobilization and cell support. In this work, we obtain first electrospun bacterial cellulose mats after chemical treatment and without conductive additives. With DMA/LiClmechanism dissolution, modified bacterial cellulose was easily electrospun in chloroform/acetone solvents in comparison with BC unmodified. FTIR peaks results are consistent with proposed interactions between cellulose and DMA/LiCl solvent system.

Scientia Iuris , 1999,
Abstract: Regarding the simple privy’s juridical interest in the outcome of the process, there is not a doctrinarian discrepancy in the understanding that the privy has freedom to act in the procedure, excepts in his powers towards the material law that is argued in the judicial proceeding. Still, there is not an unanimity in doctrine about the nature of procedure position of the privy in the simple adhesive intervention. This essays analyzes the fundamentals that give live to the doctrinal standpoints. Dado o interesse jurídico do assistente simples no resultado do processo, n o existe discrepancia doutrinária no que diz respeito ao entendimento de que tem ele liberdade de atua o processual, exceto no que diz respeito a atos de disposi o sobre o direito material controvertido no processo intervindo. Sobre a natureza da posi o processual do assistente na interven o adesiva simples, n o reina unanimidade na doutrina. O presente trabalho analisa os fundamentos que animam as posi es doutrinárias.

Abstract: Scintillators are high-density luminescent materials that convert X-rays to visible light. Thallium doped cesium iodide (CsI:Tl) scintillation materials are widely used as converters for X-rays into visible light, with very high conversion efficiency of 64.000 optical photons/MeV. CsI:Tl crystals are commercially available, but, the possibility of developing these crystals into different geometric shapes, meeting the need for coupling the photosensor and reducing cost, makes this material very attractive for scientific research. The objective of this work was to study the feasibility of using radiation sensors, scintillators type, developed for use in imaging systems for X-rays. In this paper, the CsI:Tl scintillator crystal with nominal concentration of the 10-3 M was grown by the vertical Bridgman technique. The imaging performance of CsI:Tl scintillator was studied as a function of the design type and thickness, since it interferes with the light scattering and, hence, the detection efficiency plus final image resolution. The result of the diffraction X-ray analysis in the grown crystals was consistent with the pattern of a face-centered cubic (fcc) crystal structure. Slices 25 × 2 × 3 mm3 (length, thickness, height) of the crystal and mini crystals of 1 × 2 × 3 mm3 (length, thickness, height) were used for comparison in the imaging systems for X-rays. With these crystals scintillators, images of undesirable elements, such as metals in food packaging, were obtained. One-dimensional array of photodiodes and the photosensor CCD (Coupled Charge Device) component were used. In order to determine the ideal thickness of the slices of the scintillator crystal CsI:Tl, Monte Carlo method was used.

Abstract: Objective: This study aimed to compare the cortical topographic mapping while performing cognitive activities of standardized short-term memory. Materials and Methods: The sample consisted of 30 individuals of both gender. Each individual participant of the survey was subjected to a short-term memory test for each sense. To carry out the EEG record, we used an electroencephalograph with 20 electrodes. The stimulus for the acquisition of short-term memory has always been made up of five items from different semantic classes. Results: The posterior right quadrant had a higher percentage of gamma rhythm during the tests of most senses. Conclusion: It was concluded that the right back quadrant has a higher gamma rhythms percentage during tests which involve somesthetic, olfactory and gustatory memory. On the other hand, the predominance of a gamma rhythm percentage in any quadrant when the auditory and visual memory was stimulated was not observed in this study.

Abstract: background: as a successor of cirurgia vascular e angiologia, the brazilian vascular journal (j vasc bras) is the official scientific organ of sociedade brasileira de angiologia e cirurgia vascular (sbacv) and has been making progress and achievements throughout the years. however, these achievements lead to a full commitment able to maintain a high quality standard and imply continuous challenges, not only to achieve new conquests, but also to sustain them. objective: to critically evaluate all j vasc bras publications in printed and/or electronic versions between 2002 and 2007. methods: it is a systematic review of all j vasc bras publications, both printed and electronic, released in the aforementioned period. the papers were subdivided into 12 categories and evaluated considering five aspects: a) type of publication; b) large thematic area; c) level of scientific evidence; d) references; e) country of origin of references. spsstm version 13.0 and microsoft exceltm were used for statistical analysis. there is no conflict of interest in this study. results: a total of 26 issues and nearly 400 manuscripts were evaluated, regarding all levels of scientific evidence, comprehending editorials, original and review articles, consensus and/or scientific forums, case reports, letters to the editor and final paper abstracts. the texts dealt with all large thematic areas of angiology and vascular surgery, besides bioethics, sociology, philosophy and technological innovations. however, despite a progressive paradigm shift, brazilian authors are still far from ideal with regard to appreciation of the brazilian scientific production, besides that of j vasc bras. this behavior needs to be reconsidered. conclusion: despite being young, j vasc bras has been overcoming obstacles and playing its role, both as the official scientific organ of sbacv and as a scientific journal. its achievements allow us to claim that it is in the right path, but there are still challenges to be overc
