Artificial Immune Systems with Negative Selection Applied to Health Monitoring of Aeronautical Structures

In this paper we present a system for aircraft structural health monitoring based on artificial immune systems with negative selection. Inspired by a biological process, the principle of discrimination proper/non-proper, identifies and characterizes the signs of structural failure. The main application of this method is to assist in the inspection of aircraft structures, to detect and characterize flaws and decision making in order to avoid disasters. We proposed a model of an aluminum beam to perform the tests of the method. The results obtained by this method are excellent, showing robustness and accuracy.

Cultura y comportamiento informacional en ambientes empresariales y el proceso de inteligencia competitiva

This article presents and discusses the concepts found in the literature about informational culture, informational behavior, information management, knowledge management and competitive intelligence. It focuses the correlation among those elements and shows, from theliterature analysis, the importance of the informational culture for the development of competitive intelligence in organizations.

Um mundo radicalmente melhor: criatividade, colaboração e padrão de redes como estratégias para o desenvolvimento sustentável

There are substantial evidences that the period experienced by humanity globally is unprecedented and is heading towards a major transformation that results from the Globalization. Totally conditioned to the addictions of the dominant and predatory capitalism, humanity has, for decades, exhausted natural resources, disregarded the nature of its own social existence and walked away from its humanity. It is notable, however, an impressive flow of factors that dialogue and support each other as trends that go towards sustainable development, based on the harmonious integration between Technology, Culture, Society, Environment and Economy. This emerging moment can be seen from the perspectives of the Creative Economy as economic paradigm centered on the subjectivity and the human capacity to undertake innovative services, products and solutions guided by social values. Within this fluid and dynamic global context, initiatives that legitimately intend to act sustainably are gaining space. This socioeconomic moment fosters and is fostered by new kinds of work and organization guided by the Collaboration and social structuring on Network Patterns. These new social models significantly transform the understanding and insights about the Communication flows. The HUB São Paulo, as creative and social organization that operates under the logic of Collaboration through a Network Structure, was the subject of a case study used to sustain the defense of this emerging scenario and also to perform an analysis on the new role of Communication, at perspectives of transformation of mental paradigms towards sustainability and establishment of meaningful connections

Expressão e localização de aquaporinas no epidídimo do gerbilo, Meriones unguiculatus, em diferentes fases do desenvolvimento pós-natal

Aquaporins (AQPs) are membrane protein channels expressed in a wide variety of cells and tissues that are involved in the transport of water. In the male excurrent duct, the movement of fluid and solutes across the epithelium is essential for establishing the proper luminal environment in which sperm mature and are stored. The initial aim of the present propose is to localize AQP 2 e 9 in epithelium of the initial segment, caput, corpus and cauda epididymidis in Mongolian gerbil during postnatal development (10, 30, 60, 120 and 300 days), observing possible changes in the pattern of expression of the AQPs along the postnatal development. The animals will be killed by inhalation of carbon dioxide. After euthanasia, the epididymis will be removed and the different regions will be isolated. The biological material obtained will be processed in accordance with the routines of histological techniques and imunnohistochemistry to study the expression and localization of the AQPs 2 and 9. The results obtained will be analyzed and photographed in conventional light microscope

Análise da troca de calor em sistemas de injeção de termoplásticos – um estudo de caso: polipropileno

The purpose of this work was to define the processes through which the cooling of thermoplastics parts occur inside the mold cavity in an injection process. The plastic materials have become more widespread in the automobile industry and, among its manufacturing processes, injection moulding develops quickly, allowing the manufacturing of quality parts in great volumes. Data was collected from the injection of Volkswagen Gol NF 23X (Gol Generation 5). Using approximated methods for calculation for the heat Exchange inside the mould, in the cooling system, the required water flow was determined to properly cool the parts. Comparing the obtained value with Project specifications, it was verified that the method, in spite of incurring in some mistakes, is efficient in determining the flow of cooling fluid and serves as a verification tool for the parameters defined on project, and can be applied to simple projects. The definition of the cooling system, in practice, is dependent on innumerable variables and each case must be approached in itself, since the parameters for one product may not be ideal for another

Relação entre materiais dentários e o complexo dentino-pulpar

Despite the strong valorization of the esthetics and its relationship with restorative materials, the biological principles of any clinical procedure are extremely important to maintain the vitality of the dentin-pulp complex. Dentin and pulp tissue are susceptible to different kinds of irritants such as toxins from microorganisms, traumatic procedures of cavity preparation, as well as toxic components released by restorative materials applied in non recommended clinical situations. Initially, the pulp responds to irritation by starting an inflammatory reaction which involves outward movement of dentinal fluid and intratubular deposition of immunoglobulins, upregulation of odontoblast activities, presence of immune cells and their cytokines as well as local expression of neuropeptides and chemokines. After these initial events, the inflammation process can be resolved associated or not to sclerotic dentin formation and reactionary dentin deposition. If high intensity offensive stimuli are applied to the dentin-pulp complex, death of odontoblasts takes place and consequently pulp ageing or even partial necrosis of this tissue may occurs. Thereby, clinicians need to be aware about the physiological and pathological features of the dentin-pulp complex as well as the possible biological consequences of different clinical procedures. In this way, the dentists should be able to carry out minimally aggressive operative techniques and to select the more appropriate restorative materials for each specific clinical situation in order to obtain excellent clinical results associated to the maintenance of pulp vitality.
