The rise and fall of Benedetto Croce: intellectual positionings in the Italian cultural field 1944-1947

This article evaluates the discourse developed around Benedetto Croce in the Italian cultural periodical press between 1944 and 1947 and it discusses the forms of adversarial discourse and the agents involved in the anti-Croce polemics that unfolded in the Communist party’s official cultural journal Rinascita. Specifically, this article focuses on a selection of intellectuals who moved away from Crocean idealism to embrace Marxism in order to investigate how their conversion was presented in Rinascita.

Transporters involved in glucose and water absorption in the Dysdercus peruvianus (Hemiptera: Pyrrhocoridae) anterior midgut

Little is known about insect intestinal sugar absorption, in spite of the recent findings, and even less has been published regarding water absorption. The aim of this study was to shed light on putative transporters of water and glucose in the insect midgut Glucose and water absorptions by the anterior ventriculus of Dysdercus peruvianus midgut were determined by feeding the insects with a glucose and a non-absorbable dye solution, followed by periodical dissection of insects and analysis of ventricular contents. Glucose absorption decreases glucose/dye ratios and water absorption increases dye concentrations. Water and glucose transports are activated (water 50%, glucose 33%) by 50 mM K(2)SO(4) and are inhibited (water 46%, glucose 82%) by 0.2 mM phloretin, the inhibitor of the facilitative hexose transporter (GLUT) or are inhibited (water 45%, glucose 35%) by 0.1 mM phlorizin, the inhibitor of the Na(+)-glucose cotransporter (SGLT). The results also showed that the putative SGLT transports about two times more water relative to glucose than the putative GLUT. These results mean that D. peruvianus uses a GLUT-like transporter and an SGLT-like transporter (with K(+) instead of Na(+)) to absorb dietary glucose and water. A cDNA library from D. peruvianus midgut was screened and we found one sequence homologous to GLUT1, named DpGLUT, and another to a sodium/solute symporter, named DpSGLT. Semi-quantitative RT-PCR studies revealed that DpGLUT and DpSGLTs mRNA were expressed in the anterior midgut, where glucose and water are absorbed, but not in fat body, salivary gland and Malpighian tubules. This is the first report showing the involvement of putative GLUT and SGLT in both water and glucose midgut absorption in insects. (C) 2010 Elsevier Inc. All rights reserved.

Magnetic-field asymmetry of nonlinear transport in a small ring

We have investigated the magnetic-field asymmetry of the conductance in the nonlinear regime in a small Aharonov-Bohm ring. We have found that the odd-in B and linear in V (the DC bias) correlation function of the differential conductance exhibits periodical oscillations with the Aharonov-Bohm flux. We have deduced the electron interaction constant and analyzed the phase rigidity of the Aharonov-Bohm oscillations in the nonlinear regime. Copyright (C) EPLA, 2009

Machine vision for the automatic classification of images acquired from Non-destructive tests

This project is based on Artificial Intelligence (A.I) and Digital Image processing (I.P) for automatic condition monitoring of sleepers in the railway track. Rail inspection is a very important task in railway maintenance for traffic safety issues and in preventing dangerous situations. Monitoring railway track infrastructure is an important aspect in which the periodical inspection of rail rolling plane is required.Up to the present days the inspection of the railroad is operated manually by trained personnel. A human operator walks along the railway track searching for sleeper anomalies. This monitoring way is not more acceptable for its slowness and subjectivity. Hence, it is desired to automate such intuitive human skills for the development of more robust and reliable testing methods. Images of wooden sleepers have been used as data for my project. The aim of this project is to present a vision based technique for inspecting railway sleepers (wooden planks under the railway track) by automatic interpretation of Non Destructive Test (NDT) data using A.I. techniques in determining the results of inspection.

ANALYSIS & STUDY OF AI TECHNIQUES FORAUTOMATIC CONDITION MONITORING OFRAILWAY TRACK INFRASTRUCTURE : Artificial Intelligence Techniques

Since the last decade the problem of surface inspection has been receiving great attention from the scientific community, the quality control and the maintenance of products are key points in several industrial applications.The railway associations spent much money to check the railway infrastructure. The railway infrastructure is a particular field in which the periodical surface inspection can help the operator to prevent critical situations. The maintenance and monitoring of this infrastructure is an important aspect for railway association.That is why the surface inspection of railway also makes importance to the railroad authority to investigate track components, identify problems and finding out the way that how to solve these problems. In railway industry, usually the problems find in railway sleepers, overhead, fastener, rail head, switching and crossing and in ballast section as well. In this thesis work, I have reviewed some research papers based on AI techniques together with NDT techniques which are able to collect data from the test object without making any damage. The research works which I have reviewed and demonstrated that by adopting the AI based system, it is almost possible to solve all the problems and this system is very much reliable and efficient for diagnose problems of this transportation domain. I have reviewed solutions provided by different companies based on AI techniques, their products and reviewed some white papers provided by some of those companies. AI based techniques likemachine vision, stereo vision, laser based techniques and neural network are used in most cases to solve the problems which are performed by the railway engineers.The problems in railway handled by the AI based techniques performed by NDT approach which is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion. The NDT approach ensures the uniformity, quality and serviceability of materials without causing any damage of that materials is being tested. This testing methods use some way to test product like, Visual and Optical testing, Radiography, Magnetic particle testing, Ultrasonic testing, Penetrate testing, electro mechanic testing and acoustic emission testing etc. The inspection procedure has done periodically because of better maintenance. This inspection procedure done by the railway engineers manually with the aid of AI based techniques.The main idea of thesis work is to demonstrate how the problems can be reduced of thistransportation area based on the works done by different researchers and companies. And I have also provided some ideas and comments according to those works and trying to provide some proposal to use better inspection method where it is needed.The scope of this thesis work is automatic interpretation of data from NDT, with the goal of detecting flaws accurately and efficiently. AI techniques such as neural networks, machine vision, knowledge-based systems and fuzzy logic were applied to a wide spectrum of problems in this area. Another scope is to provide an insight into possible research methods concerning railway sleeper, fastener, ballast and overhead inspection by automatic interpretation of data.In this thesis work, I have discussed about problems which are arise in railway sleepers,fastener, and overhead and ballasted track. For this reason I have reviewed some research papers related with these areas and demonstrated how their systems works and the results of those systems. After all the demonstrations were taking place of the advantages of using AI techniques in contrast with those manual systems exist previously.This work aims to summarize the findings of a large number of research papers deploying artificial intelligence (AI) techniques for the automatic interpretation of data from nondestructive testing (NDT). Problems in rail transport domain are mainly discussed in this work. The overall work of this paper goes to the inspection of railway sleepers, fastener, ballast and overhead.

Corpos amputados e suas próteses : a intervenção técnica (re)inventando formas de ser e de habitar o corpo na contemporaneidade

Baseada na perspectiva teórica do campo dos Estudos Culturais e sócio-históricos sobre o corpo, esta dissertação analisou os significados culturais que os indivíduos atribuíam aos seus corpos e suas vidas cotidianas após terem sido submetidos a amputação e se tornarem usuários de prótese. O material empírico foi coletado através da observação participante, do diário de campo e da entrevista semi-estruturada, realizada numa clínica ortopédica privada, situada em Porto Alegre, especializada na reabilitação e protetização de indivíduos que foram submetidos a amputação. O grupo participante do estudo foi: o fisioterapeuta e o protesista, e por nove pacientes da clínica, homens e mulheres, todos amputados de um membro inferior, com idades variando entre 18 e 82 anos, sendo que apresentavam em comum o fato de terem se tornado amputados após um acidente ou em decorrência da diabete. A pesquisa de campo foi desenvolvida no período de Fevereiro de 2003 a Setembro de 2003, através da participação de sessões de fisioterapia, das reuniões mensais dos grupos de apoio aos amputados, onde foi acompanhado o processo de adaptação à prótese. O estudo consistiu em problematizar os efeitos provocados na vida cotidiana destes indivíduos pelas transformações ocorridas em seus corpos secundários à amputação, bem como aqueles produzidos pelo "acoplamento" com a prótese, buscando tornar visível o processo vivenciado por eles, ou seja, o estranhamento e a naturalização do seu "novo" corpo fabricado pelas tecnologias. A dissertação representa, portanto, as reflexões construídas a partir da investigação desenvolvida especificamente neste grupo, onde o corpo amputado e protetizado foi vislumbrado como algo produzido e ressignificado na cultura, sendo assim moldável, provisório e reinventado continuamente.

Análise das condições ergonômicas da situação de trabalho dos auxiliares de enfermagem em uma unidade de interação hospitalar

O objetivo do presente estudo foi investigar as condições ergonômicas da situação de trabalho dos Auxiliares de Enfermagem em uma unidade de clínica geral de um hospital privado na cidade de Curitiba, Paraná, bem como sugerir melhorias a partir da situação caracterizada. Com a aplicação do método da Análise Ergonômica do Trabalho (AET), pôde-se verificar a realidade desses profissionais, caracterizando suas tarefas, registrando a existência de distanciamento entre tarefa prescrita e real. Os resultados obtidos evidenciaram problemas no âmbito organizacional como a montagem inadequada da escala de divisão de pacientes, o quadro de pessoal abaixo da exigência mínima estabelecida pelo Conselho Federal de Enfermagem (COFEN), a falta e a má conservação de materiais e equipamentos e, em relação ao posto de trabalho, o dimensionamento inadequado dos espaços para trânsito de pessoas e equipamentos. Concluiu-se que os problemas de maior relevância são de origem organizacional e que os mesmos favorecem e, até mesmo, intensificam os relativos ao posto de trabalho, contribuindo para o elevado índice de atestados e insatisfação entre os Auxiliares de Enfermagem. O estudo é finalizado com sugestões de melhorias, entre elas, o redimensionamento do número de leitos nas enfermarias e quadro de pessoal, promoção de rodízio dos Auxiliares de Enfermagem entre postos de diferentes níveis de exigência, escalonamento apropriado na distribuição de pacientes de acordo com a gravidade do quadro clínico, formação de comitês com reuniões periódicas para discussão de problemas existentes e outras possíveis soluções.
