Sistema inteligente para la selección de brocas de perforación de pozos

The present work begins with a review of the literature on bit selection methods for oil well drilling. A proposal for the structure and organization of a drilling database and a knowledge base, is described. Previous studies formed the principal elements in the process of selection of drills for proposed drilling. The procedure was implemented as a computer system for the selection of tricone bits. A drilling bit database for three different Brazilian sedimentary basins was obtained for several wells drilled, and knowledge was collected from drilling engineers from different fields both electronically and also by means of interviews. It can be concluded that the selection process showed good results based on tests, which were carried out.

Osteotomia com brocas de alta e baixa rotação, com e sem refrigeração líquida: estudo histopatológico duplo cego em suínos

Nine swines of the White Large race were used for study of the process of bony repair after osteotomy with rotating instruments of low and high-speed, with and without liquid refrigeration. The authors observed, through double blind histopathological analysis, that in every analyzed operative time, the bony repair was processed more appropriately when the osteotomies were accomplished with liquid refrigeration. In the final postoperative times, of fourteen and twenty-eight days, the best results of bony repair were observed in the osteotomy accomplished with drills of low rotation and with liquid refrigeration, while in the postoperative time of seven days, the results of the bony repair of osteotomy accomplished with drills of high rotation and with liquid refrigeration they were better. The authors consider, still, that the process of bony repair in swine display larger proximity in the histological pictures among the studied variables, when compared with other biological models. As most of the works told in the literature it refers the use of dogs, the authors consider that the present work guarantees your importance in the sense of looking for a closer model of the man.

Introdução da comunicação suplementar e alternativa na terapia com afásicos

Sabe-se que o tratamento fonoaudiológico de pacientes com afasia severa é limitado. A ausência de fala articulada, algumas vezes, impede o diagnóstico da afasia. O paciente grave pode não falar devido à inabilidade de articulação, como ocorre na disartria e/ou apraxia. Essa ausência de fala não permite afirmar se a linguagem está comprometida. O uso da comunicação suplementar e alternativa tem sido um método eficaz na reabilitação desses pacientes. Esse estudo visou descrever o uso da comunicação suplementar e alternativa associada a outras modalidades de linguagem (escrita, gestos), a partir do relato de dois casos de afasia. A análise dos dados foi composta por dois blocos: a introdução da comunicação suplementar e alternativa no diálogo; e o uso da leitura e escrita associado aos símbolos. A comunicação suplementar e alternativa foi um apoio para a oralidade, leitura e escrita dos pacientes.

Analysis of speech fluency in Williams syndrome

Williams syndrome (WS) is a neurodevelopmental genetic disorder, often referred as being characterized by dissociation between verbal and non-verbal abilities, although the number of studies disputing this proposal is emerging. Indeed, although they have been traditionally reported as displaying increased speech fluency, this topic has not been fully addressed in research. In previous studies carried out with a small group of individuals with WS, we reported speech breakdowns during conversational and autobiographical narratives suggestive of language difficulties. In the current study, we characterized the speech fluency profile using an ecologically based measure - a narrative task (story generation) was collected from a group of individuals with WS (n = 30) and typically developing group (n = 39) matched in mental age. Oral narratives were elicited using a picture stimulus - the cookie theft picture from Boston Diagnosis Aphasia Test. All narratives were analyzed according to typology and frequency of fluency breakdowns (non-stuttered and stuttered disfluencies). Oral narratives in WS group differed from typically developing group, mainly due to a significant increase in the frequency of disfluencies, particularly in terms of hesitations, repetitions and pauses. This is the first evidence of disfluencies in WS using an ecologically based task (oral narrative task), suggesting that these speech disfluencies may represent a significant marker of language problems in WS.

Stroke in ancient times - a reinterpretation of Psalms 137 : 5,6

Stroke was probably first described in Psalms 136: 5-6 of the Catholic Bible, and Psalms 137:5-6 of the Evangelical Bible. Based on the Portuguese, Spanish, English, German, Dutch, Russian, Greek, and original Hebrew Bible, the significance of this Psalm is the invocation of a punishment, of which the final result would be a stroke of the left middle cerebral artery, causing motor aphasia and right hemiparesis.

Myiasis in Palate by Cochliomyia hominivorax

Myiasis is the infestation of tissues and organs of animals and humans caused by the larvae of certain dipteran flies. It is more common in undeveloped and tropical countries and usually affects elderly patients, persons who are sick, and patients with mental illness. Oral myiasis is a rare pathologic condition and a risk to the patient's life because of its great destructive potential. Therefore, appropriate treatment is necessary. This article aimed to report a case of myiasis caused by Cochliomyia hominivorax in the palate of a patient with primary progressive aphasia, which was successfully treated through mechanical removal of larvae plus administration of ivermectin.

AFASIA MOTORA, PARALISIA FACIAL E HEMIPLEGIA DIREITA APOS ABSCESSO DENTARIO A ESQUERDA

The authors report a case of a 6 year old child who presented with dental abscess associated with a parietal and frontal cerebrite, right facial paralysis and motor aphasia. The clinical findings, radiological examination including computerized tomography and type of treatment are presented. At beginning, the patient did not respond to antimicrobial therapy and only after drainage of her dental abscess revealed good clinical evolution.

A emergência da noção de comportamento simbólico em neuropsicopatologia

In this article, we present the notion of symbolic behavior in accordance with neuropsychopathology research from the first decades of the past century, carried out particularly in the context of aphasia research. The guiding axis was the presence of this notion in the first work by Merleau-Ponty, The structure of behavior. Based on research by Gelb and Goldstein, the philosopher takes ownership of the semantics of the symbolic and characterizes human corporality based on its capacity to move beyond the immediate nature of the experienced situations. We also show that the circumscription of symbolic behavior was conditioned by theoretical-methodological changes that permitted the passage from localizationist conceptions to globalist attitudes in view of pathological events of cerebral origin.
