Comunicação interna: uma questão de qualidade

Internal Communications, a central theme of this project, it is essential to support a transparent and effective cooperation between organization and em ployee. In companies with Quality Management System, as certified in ISO 9001, need to adhere to the quality not only in its management policy, but as in all of its processes and the various agencies in which there is interaction, especially the internal. This paper aims to reflect on the interaction with the internal audience, paying attention to the fact that the information required and the strategic management of public relations positively interfere in the relationship between organization and employe e and the resulting benefits that these entail in quality management. The demonstration of the policies employed by the company Vien a Grafica & Editora as the basis for developing a model suggestive of internal communication in business quality. Thus, we intend to understand how effective communication arouses feelings of motivation and engagement among employees, so there is the realization of quality in all organizational sectors

Microwave-assisted hydrothermal synthesis of NiO-Ce1-XEuxO2-δ powders for fuel cell catalytic anodes

CeO2-based materials doped with rare earth (TR +3) can be used as alternative to traditional NiO-YSZ anodes in solid oxide fuel cells as they have higher ionic conductivity and lower ohmic losses compared to YSZ. Moreover, they allow fuel cell operation at lower temperatures (500-800°C). In the anode composition, the concentration of NiO acting as catalyst in YSZ provides high electrical conductivity and high electrochemical activity of reactions, promoting internal reform in the cell. In this work, NiO - Ce1-xEuxO2-δ compounds (x = 0.1, 0.2 and 0.3) have been synthesized by microwave-assisted hydrothermal method. The materials were characterized by TG, XRD, TPR and SEM-FEG techniques. The refinement of data obtained by X-ray diffraction showed the presence of ceria doped with europium crystallized in a cubic phase with fluorite structure, in addition to the presence of NiO. The microwave-assisted hydrothermal method showed significant reduction in the average particle size and good mass control of phase compositions compared to other chemical synthesis techniques.

Movimento dos olhos e controle postural

The control of stances such as the upright stance seems not to have a purpose in itself; this control could facilitate the execution of other simultaneous tasks, the so-called suprapostural tasks. The goal of this study was to determine the effects of saccadic eye movements on the control of posture. Twelve adult participants had their body oscillations analyzed while standing upright, for 70 s, in the postural conditions of feet apart and feet together, performing fixation in the central target or horizontal saccadic movements, in the conditions slow (0,5 Hz) and fast (1,1 Hz). The results showed that saccadic movements, independently of their frequency, strongly reduced trunk and head oscillations in the anterior-posterior (AP) axis. In this axis, there was an effect of feet position only in head oscillation. In the medio-lateral (ML) axis, the results showed a strong effect of feet position with body oscillation decreased in the condition of feet apart. The effect of the visual task in the ML axis occurred only for trunk oscillation, not reaching significance level in the pairewise comparisons. In the AP axis, the data corroborate a facilitatory explanation of the control of posture: the reduction in body oscillation limited the variations of the stimulus image projected on the retina, facilitating the execution of saccadic movements as compared to fixation. In the ML axis, the effect of reducing the basis of support was more evident than the effect of saccadic movements, suggesting that the available resources were used primarily for the postural task in detriment of the visual task. Additionally, aspects like attentional focus and sensory information pick up are discussed as mechanisms involved in this task

Caracterização geofísica no Gabro Santa Catarina, São Sepé (RS)

Geophysical methods are widely used in mineral exploration for several types of mineral deposits. When combined with direct studies as geochemistry, a substantial increase in the probability of ore discovery is possible in mineral exploration activities. Electrical geophysical methods are particularly promising in studies related to the search of sulphides due to the contrast of physical properties electric resistivity and chargeability. This paper presents the results obtained from the application of Resistivity (DC) and Induced Polarization methods, through the electrical profiling technique, aiming at evaluating the potential mineral of a gabbro intruded in a metasedimentary sequence, in an area where several occurrences of gold and copper were described. This gabbro is ranked on the Basic-Ultrabasic stratiform bodies, which gather peridotites, gabbros, and layered anortosites. Three radial lines of electrical profiling were performed, spaced of 60° and crossing at the area center, with readings of electric resistivity and chargeability in Wenner-Schlumberger array. The association of low resistivity and high chargeability areas has allowed defining potentially mineralized zones related to structures that condition the drainage net in the gabbro domain. Grains of gold detected through geochemical prospection of alluvial sediments dowstream from the gabbro may have originated from leaching of ores deposited in fractures through the action of river waters within the gabbro domain, possibly consisting of sulphides and gold.

Use of Chlorine to Remove Magnesium from Molten Aluminum

Removal of Mg from aluminum scraps, known as demagging, has been widely applied in the,aluminum industry. This work discusses bubble-formation theories and magnesium kinetic removal from aluminum scraps using chlorine and inert gas fluxing. The interfacial area of the bubbles and residence time were estimated using a mathematical model. To inject gaseous chlorine, three types of nozzles were used with varying internal diameter. In addition, a porous plug, as well as varying input chlorine flow and concentration were used. The use of lower chlorine concentration improves efficiency because the interfacial tension is reduced therefore, more and smaller bubbles are formed. The model proposed herein is consistent with the experimental data. [doi:10.2320/matertrans.M2011256]

Análise do conforto térmico na obra de João Filgueiras Lima, Lelé: Hospitais Sarah de Salvador e do Rio de Janeiro

Estratégias passivas de projeto reduzem significativamente o uso de ar condicionado e melhoram o conforto térmico dos usuários. Isto pode ser ilustrado através dos hospitais da Rede Sarah Kubitschek projetados pelo arquiteto João Filgueiras Lima, Lelé, cujas soluções além de propiciarem ambientes mais agradáveis e salubres, evitam o uso de sistemas mecânicos de resfriamento, reduzindo o consumo de energia elétrica. Deste modo, o presente artigo tem como objetivo avaliar o conforto térmico dos hospitais Sarah de Salvador e do Rio de Janeiro, através de medições in loco da temperatura do ar, umidade relativa do ar e velocidade do ar. A análise dos resultados foi baseada em leituras de projeto, na norma ASHRAE Standard 55/2004 e em parâmetros adquiridos na literatura especializada. Os resultados demonstram a preocupação de Lelé na incorporação de aspectos bioclimáticos nos projetos. No Sarah - Salvador, alguns ambientes permaneceram fora da zona de conforto no período do meio dia, devido ao ganho de calor pela cobertura. No entanto, o uso da ventilação natural auxilia no efeito de resfriamento, melhorando o conforto térmico nos espaços internos. Já no Sarah - Rio, todos os ambientes permanecem dentro da zona de conforto proposta pela ASHRAE 55.

Aumento de fijación de nitrógeno en diazótrofos unicelulares versus Trichodesmium tras un evento de deposición de polvo atmosférico en las Islas Canarias

[ES]En este trabajo hemos estudiado la relación entre la deposición de polvo atmosférico, y la abundancia y tasas de fijación de nitrógeno asociadas a Trichodesmium y fijadores unicelulares en las Islas Canarias. La fijación de nitrógeno asociada a los fijadores unicelulares aumentó entre el 86 y el 92% tras un evento de deposición de polvo atmosférico, mientras que la asociada a Trichodesmium disminuyó entre el 34 y el 92%. Tras el evento de deposición de polvo, aumentó la abundancia de fijadores unicelulares y la mayoría de éstos aparecieron asociados a partículas de materia orgánica. Creemos que esta estrategia les permite ligar el hierro que contiene el polvo y así poder usar este nutriente limitante.

Il concetto di sezione nel metodo compositivo di Aldo Rossi.

Purpose of this research is to deepen the study on the section in architecture. The survey aims as important elements in the project Teatro Domestico by Aldo Rossi built for the XVII Triennale di Milano in 1986 and, through the implementation on several topics of architecture, verify the timeliness and fertility in the new compositional exercises. Through the study of certain areas of the Rossi’s theory we tried to find a common thread for the reading of the theater project. The theater is the place of the ephemeral and the artificial, which is why his destiny is the end and the fatal loss. The design and construction of theater setting has always had a double meaning between the value of civil architecture and testing of new technologies available. Rossi's experience in this area are clear examples of the inseparable relationship between the representation of architecture as art and design of architecture as a model of reality. In the Teatro Domestico, the distinction between representation and the real world is constantly canceled and returned through the reversal of the meaning and through the skip of scale. At present, studies conducted on the work of Rossi concern the report that the architectural composition is the theory of form, focusing compositional development of a manufacturing process between the typological analysis and form invention. The research, through the analysis of some projects few designs, will try to analyze this issue through the rules of composition both graphical and concrete construction, hoping to decipher the mechanism underlying the invention. The almost total lack of published material on the project Teatro Domestico and the opportunity to visit the archives that preserve the drawings, has allowed the author of this study to deepen the internal issues in the project, thus placing this search as a first step toward possible further analysis on the works of Rossi linked to performance world. The final aim is therefore to produce material that can best describe the work of Rossi. Through the reading of the material published by the same author and the vision of unpublished material preserved in the archives, it was possible to develop new material and increasing knowledge about the work, otherwise difficult to analyze. The research is divided into two groups. The first, taking into account the close relationship most frequently mentioned by Rossi himself between archeology and architectural composition, stresses the importance of tipo such as urban composition reading system as well as open tool of invention. Resuming Ezio Bonfanti’s essay on the work of the architect we wanted to investigate how the paratactic method is applied to the early work conceived and, subsequently as the process reaches a complexity accentuated, while keeping stable the basic terms. Following a brief introduction related to the concept of the section and the different interpretations that over time the term had, we tried to identify with this facility a methodology for reading Rossi’s projects. The result is a constant typological interpretation of the term, not only related to the composition in plant but also through the elevation plans. The section is therefore intended as the overturning of such elevation is marked on the same plane of the terms used, there is a different approach, but a similarity of characters. The identification of architectural phonemes allows comparison with other arts. The research goes in the direction of language trying to identify the relationship between representation and construction, between the ephemeral and the real world. In this sense it will highlight the similarities between the graphic material produced by Ross and some important examples of contemporary author. The comparison between the composition system with the surrealist world of painting and literature will facilitate the understanding and identification of possible rules applied by Rossi. The second part of the research is characterized by a focus on the intent of the project chosen. Teatro Domestico embodies a number of elements that seem to conclude (assuming an end point but also to start) a curriculum author. With it, the experiments carried out on the theater started with the project for the Teatrino Scientifico (1978) through the project for the Teatro del Mondo (1979), into a Laic Tabernacle representative collective and private memory of the city. Starting from a reading of the draft, through the collection of published material, we’ve made an analysis on the explicit themes of the work, finding the conceptual references. Following the taking view of the original materials not published kept at Aldo Rossi's Archive Collection of the Canadian Center for Architecture in Montréal, will be implemented through the existing techniques for digital representation, a virtual reconstruction of the project, adding little to the material, a new element for future studies. The reconstruction is part of a larger research studies where the current technologies of composition and representation in architecture stand side by side with research on the method of composition of this architect. The results achieved are in addition to experiences in the past dealt with the reconstruction of some of the lost works of Aldo Rossi. A partial objective is to reactivate a discourse around this work is considered non-principal, among others born in the prolific activities. Reassessment of development projects which would bring the level of ephemeral works most frequented by giving them the value earned. In conclusion, the research aims to open a new field of interest on the part not only as a technical instrument of representation of an idea but as an actual mechanism through which composition is formed and the idea is developed.

Design and Setup of a New HPGe Detector Based Body Counter Capable of Detecting Also Low Energy Photon Emitters

The present work describes the development of a new body-counter system based on HPGe detectors and installed at IVM of KIT. The goal, achieved, was the improvement of the ability to detect internal contaminations in the human body, especially the ones concerning low-energy emitters and multiple nuclides. The development of the system started with the characterisation of detectors purchased for this specific task, with the optimisation of the different desired measurement configurations following and ending with the installation and check of the results. A new software has been developed to handle the new detectors.

Extended arm polyphenylene dendrimers

In order to eliminate the de Gennes packing problem, which usually limits the attainable size of dendrimers, a new branching unit containing para-tetraphenylene ethynyl arms has been synthesized and utilized in the preparation of dendrimers of the Müllen type. The divergent principle of synthesis, based on the Dilthey reaction, could be carried up to sixth generation which contains 2776 benzene rings and possesses a diameter in the 27 nm range ("exploded dendrimer"). Monodispersity and dimensions of this and the lower generation species have been studied by MALDI-TOF MS (including the very recent superconducting tunnel junction detector), by size-exclusion chromatography, dynamic light scattering, transmission electron microscopy, and atomic force microscopy. Interesting features, apart from the huge dimension, are the low density and high porosity of these giant molecules which cause extensive aggregation in the gas phase, flattening on solid support (AFM) and the ready incorporation of guest molecules in the condensed phase. Since the synthesis of the para-tetraphenylene arms is quite elaborate, similar dendrimers containing para-terphenylene arms have been prepared; they are accessible more economically ("semi-exploded dendrimers"). It has been shown that they in several aspects mimic the features of the "exploded dendrimers". In order to take advantage of the presence of large internal cavities in this dendrimer type, dendrons containing -C≡C- triple bonds have also been incorporated. Surprisingly, they are readily hydrogenated under the condition of heterogeneous catalysis (Pd/C) which demonstrates the large size of the cavities. As revealed by a quartz microbalance study the post-hydrogenation dendrimers are less prone to incorporate guest molecules than before hydrogenation. Obviously, the more flexible nature of the former reduces porosity, it also leads to significant shrinkage. An interesting perspective is the use of homogeneous hydrogenation catalysts of variable size with the aim of determining the dimension of internal free space.

Optimierung der Inhalationstherapie bei Kindern und Mukoviszidose-Patienten

Die pulmonale Applikation von Arzneimitteln hat in den vergangenen Jahren zu- rnnehmend an Bedeutung gewonnen und wird vor allem in der lokalen Therapie bei Asthma, COPD und Mukoviszidose genutzt. Als neues innovatives Inhalationsgerät befindet sich der Respimat® seit 2004 auf dem Arzneimittelmarkt und ist bisher nur für Erwachsene zugelassen. Daher wurden im Rahmen dieser Arbeit die Anwendbarkeit und die Modifikation des Respimats® bei Kindern untersucht. Zusammenfassend zeigen die Ergebnisse, dass Kinder ab einem Alter von fünf Jahren fähig sind suffizient mit dem Respimat® zu inhalieren und gute Werte für die estimierte Intrathorakaldosis zu erreichen. Besonders Kinder von 9-12 Jahren und Patienten mit DPI- oder Autohaler®-Inhalationserfahrung erreichten aufgrund eines hohen Atemflusses eine niedrigere estimierte Intrathorakaldosis als es das Potenzial des Respimats® erlaubt hätte. Durch den Einbau eines höheren internen Widerstands in den Orginalrespimat® wurde der Atemfluss signifikant verlangsamt und die Intrathorakaldosis erhöht. Des Weiteren wurden in der vorliegenden Arbeit die physikalisch-chemische Kompatibilität und die aerodynamischen Eigenschaften von Mischinhalationslösung/-suspensionen untersucht. In der Praxis mischen Muko-viszidose-Patienten oftmals mehrere Fertigarzneimittel und inhalieren diese simultan. Dadurch wird der Zeitaufwand der täglichen Inhalation reduziert und die Compliance sowie die Lebensqualität verbessert. Die 4er Kombination aus Colistimethat mit konservierungsmittelfreier Salbutamolsulfat, Ipratropiumbromidinhalationslösungen und Fluticason-17-propionatinhalationssuspension erwies sich als physikalisch-chemisch kompatibel. Die entwickelte mikrobiologische Wertbestimmungsmethode erwies sich als robust, präzise, gut reproduzierbar und erfüllte alle Anforderungen des statistischen Modells. Weiterhin wurden die aerodynamischen Eigenschaften einer praxisrelevanten 3er Mischinhalationssuspension aus Salbutamolsulfat, Ipratropiumbromid und Fluticason-17-propionat im Vergleich zu deren konsekutiven Vernebelung mittels Kaskadenimpaktion betrachtet. Die Charakteristik des erzeugten Aerosols änderte sich für simultan vernebeltes Salbutamolsulfat und Ipratropiumbromid nicht, wohingegen Fluticason-17-propionat bei simultaner Vernebelung eine Reduktion des MMADs, der delivered dose und der recovery aufwies. Dennoch ist die inhalative Glukokortikoiddosis ausreichend hoch um eine effektive antiinflammatorische Wirkung zu gewährleisten. Daher kann die simultane Inhalation der 3er Kombination empfohlen werden und somit die Compliance und die Lebensqualität von Mukoviszidosepatienten erhöht werden.rn
