Contratos de terceirização de manutenção industrial na modalidade risco: análise comparativa das avaliações e expectativas entre o setor industrial e as empresas fornecedoras de serviços

O objetivo principal deste trabalho é avaliar as formas de contratação de manutenção industrial praticadas nos últimos anos e identificar os elementos que devem ser considerados na elaboração de um contrato baseado em performance, com remuneração variável e cláusulas de risco, sob a óptica de quem contrata (indústrias) e de quem fornece (empresas especializadas) esse tipo de serviço. Para se chegar ao modelo sugerido, o estudo utiliza uma analogia com o "jogo da forca" (jogo infantil de salão que baseia-se no processo de tentativa e erro) para desenvolver um processo de desconstrução dos modelos atuais de contratação de manutenção, identificando os fatores determinantes (para cada forma de contrato mais utilizada) para o insucesso financeiro e operacional atualmente percebido. Após a tentativa de ordenação das causas dos problemas correntes, o trabalho passa para o objetivo principal, que é o de listar os fatores críticos de sucesso para um contrato de manutenção por performance e, finalmente, sugerir um modelo básico de atuação para que os resultados almejados sejam obtidos. Com a identificação e implementação desses elementos num novo modelo de contrato de risco de manutenção, acredita-se ser possível minimizar os problemas comerciais e operacionais que atualmente representam obstáculos ao sucesso da terceirização da manutenção em plantas industriais, particularmente no Brasil . A metodologia se baseia em análise dos resultados de pesquisa de campo através de questionário realizado junto aos principais gestores de grandes grupos industriais e com os executivos das empresas prestadoras de serviço de manutenção industrial.

Sacredness of the constitutional text and interpretative heresy: the Brazilian Supreme Court decision on same-sex civil unions

The paper provides a close lecture of the arguments and methods of legal construction, employed in the extensive individual opinions written by the Justices of the Brazilian Supreme Court in the case which authorized the same sex civil union. After tracing an outline of the legal problem and his possible solutions, we analyze the individual opinions, showing their methodological syncretism, the use of legal methods and arguments in a contradictory way as well the deficiencies in the reasoning. The Justices use legal arguments, but do not meet the requirements of rationality in the decision-making. We have a rhetorical attempt that aims to satisfy the public opinion than to offer a comprehensive and coherent solution according the normative elements of the Brazilian Federal Constitution of 1988.

Neue medien und text: privatbrief und private E-Mail im vergleich

Die vorliegende Dissertation setzt sich mit dem Phänomen ›Text im Rahmen der Neuen Medien‹ auseinander, indem sie theoretisch und empirisch der in der einschlägigen Forschung aufgeworfenen (und kontrovers diskutierten) Frage nachgeht, ob die Sprache in den Textsorten der neuen Kommunikationsformen als neue Schriftlichkeit bzw. schriftliche Mündlichkeit zu verstehen sei. Dabei konzentriert sie sich exemplarisch auf die Analyse eigens für diesen Zweck erstellter aktueller Textkorpora der Kommunikationsformen E-Mail und Brief und untersucht sie unter den Gesichtspunkten Mündlichkeit / Schriftlichkeit bzw. Nähe / Distanz. ›Kapitel 1‹ umreißt den Forschungsstand zum Thema ›Text und Textsorte‹ sowohl in der Textlinguistik als auch in aktuellen Studien zur Sprache in den Neuen Medien. ›Kapitel 2‹ ist dem kritischen Referat verschiedener bekannter Modelle gewidmet, die sich mit dem Aspekt der Mündlichkeit und Schriftlichkeit bzw. Nähe und Distanz beschäftigen (Hugo Stegers Freiburger Gruppe, Ludwig Söll, Koch/Oesterreicher und Ágel/Hennig) und eine Verortung von Textsorten im Kontinuum Nähe und Distanz vornehmen (Koch/Oesterreicher und Ágel/Hennig).›Kapitel 3‹ schlägt Korrekturen und Ergänzungen betreffend Punktgebung, Modellglossar und Makroanalyse im Modell von Ágel/Hennig vor, das in dieser Arbeit den Analysen der Nähesprachlichkeit in Privatbriefen und privaten E-Mails zugrunde liegt. ›Kapitel 4‹ setzt sich mit Aspekten der beiden Textkorpora auseinander, auf die sich diese Arbeit stützt, und beschreibt und erläutert den Fragebogen, der im Rahmen dieser Arbeit erstellt und Probanden zur Beantwortung vorgelegt wurde. ›Kapitel 5‹ nimmt einen ausführlichen Vergleich der Textsorten ›Privatbrief und private E-Mail‹ vor und beleuchtet abrissartig die Geschichte beider Kommunikationsformen, wobei es sich gleichzeitig auch kritisch mit den in der Forschung in solchen Vergleichsfragen vertretenen Positionen auseinander setzt. ›Kapitel 6‹ interpretiert die Ergebnisse der in der Arbeit durchgeführten Näheanalysen und zieht daraus die Schlussfolgerungen.

Molecular analysis of the bacterial diversity in a specialized consortium for diesel oil degradation

Diesel oil is a compound derived from petroleum, consisting primarily of hydrocarbons. Poor conditions in transportation and storage of this product can contribute significantly to accidental spills causing serious ecological problems in soil and water and affecting the diversity of the microbial environment. The cloning and sequencing of the 16S rRNA gene is one of the molecular techniques that allows estimation and comparison of the microbial diversity in different environmental samples. The aim of this work was to estimate the diversity of microorganisms from the Bacteria domain in a consortium specialized in diesel oil degradation through partial sequencing of the 16S rRNA gene. After the extraction of DNA metagenomics, the material was amplified by PCR reaction using specific oligonucleotide primers for the 16S rRNA gene. The PCR products were cloned into a pGEM-T-Easy vector (Promega), and Escherichia coli was used as the host cell for recombinant DNAs. The partial clone sequencing was obtained using universal oligonucleotide primers from the vector. The genetic library obtained generated 431 clones. All the sequenced clones presented similarity to phylum Proteobacteria, with Gammaproteobacteria the most present group (49.8 % of the clones), followed by Alphaproteobacteira (44.8 %) and Betaproteobacteria (5.4 %). The Pseudomonas genus was the most abundant in the metagenomic library, followed by the Parvibaculum and the Sphingobium genus, respectively. After partial sequencing of the 16S rRNA, the diversity of the bacterial consortium was estimated using DOTUR software. When comparing these sequences to the database from the National Center for Biotechnology Information (NCBI), a strong correlation was found between the data generated by the software used and the data deposited in NCBI.

SAMVC sistema de autoria de museus virtuais colaborativos

The use of graphical objects three-dimensional (3D) multimedia applications is gaining more space in the media. Networks with high transmission rates, computers with large processing and graphics boost and popularize such three-dimensional applications. The areas of 3D applications ranging from military applications, entertainment applications geared up for education. Within the applications related to education, we highlight the applications that create virtual copies of cultural spaces such as museums. Through this copy, you can virtually visit a museum, see other users, communicate, exchange information on works, etc. Thereby allowing the visit museums physically distant remote users. A major problem of such virtual environments is its update. By dealing with various media (text, images, sounds, and 3D models), its subsequent handling and update on a virtual environment requires staff with specialized knowledge. Speaking of museums, they hardly have people on your team with this profile. Inside the GT-MV (Grupo de Trabalho de Museus Virtuais), funded by RNP (Rede Nacional de Ensino e Pesquisa) propose a portal for registration, amendment and seen collaborative virtual museums of Brazil. The update, be it related to work or physical space, a system with a national scale like this, would be impossible if done only by the project team. Within this scenario, we propose the modeling and implementation of a tool that allows editing of virtual spaces in an easy and intuitive as compared with available tools. Within the context of GT-MV, we apply the SAMVC (Sistema de Autoria de Museus Virtuais Colaborativos) to museums where curators build the museum from a 3D floor plan (2D). The system, from these twodimensional information, recreates the equivalent in three dimensions. With this, through little or no training, team members from each museum may be responsible for updating the system

Rotavirus gastroenteritis in a children's hospital specialized in craniofacial malformations

This study aimed to verify the relationship between acute diarrhea provoked by rotavirus and different indicators of craniofacial malformations. In the Hospital for Rehabilitation of Craniofacial Anomalies, 8,724 children with cleft lip and cleft palate were divided into the following groups: acute diarrhea and infection due to rotavirus (C1, n = 62), acute diarrhea (C2, n = 153) and without acute diarrhea (C3, n = 8,509). In C1, 29.03% of the cases consisted of hospital infections associated with the hospitalization period while 38.71% of the patients were aged less than six months. The percentage of children not having breastfed was significantly higher in acute diarrhea groups. Additionally, there was a seasonal prevalence of rotavirus infection between May and October. Finally, the present findings indicate that rotavirus is a predominant etiological agent for gastroenteritis in children with craniofacial malformations. Moreover, among infants younger than six months of age, type of craniofacial malformation, breastfeeding difficulty, socioeconomic level and longer hospitalization period appear to contribute to higher infection morbidity.

The specialized reproductive mode of the treefrog Aplastodiscus perviridis (Anura : Hylidae)

Males of the South American treefrog Aplastodiscus perviridis construct concealed subterranean nests. Using a complex courtship behavior that involves tactile stimuli and vocalizations, males guide the females to the subterranean nests where eggs are laid. Embryos and facultatively oophagous tadpoles (at least in stage 25) stay in subterranean nests until flooding transports them to ponds or streams. This is a rare reproductive mode previously known for few species in the Hyla albosignata and H. albofrenata complexes. Based on similarities of reproductive mode we suggest a monophyletic origin for Aplastodiscus and these complexes of Hyla.

A specialized midgut region in stingless bees (Hymenoptera: Apidae: Meliponinae)

Ultrastructure of the anterior end of the midgut of three Neotropical stingless bees, including an obligate necrophagous species Trigona hypogea, suggests that this midgut region has no role in nutrient absorption because its lumen is reduced by a thick cuticle that lines the outer epithelium of the cardiac valve. A possible involvement of this midgut region in the production of the peritrophic membrane compounds is discussed.

Built to Bite: Feeding Kinematics, Bite Forces, and Head Shape of a Specialized Durophagous Lizard, Dracaena Guianensis (Teiidae)

Most lizards feed on a variety of food items that may differ dramatically in their physical and behavioral characteristics. Several lizard families are known to feed upon hard-shelled prey (durophagy). Yet, specializations toward true molluscivory have been documented for only a few species. As snails are hard and brittle food items, it has been suggested that a specialized cranial morphology, high bite forces, and an adapted feeding strategy are important for such lizards. Here we compare head and skull morphology, bite forces, and feeding kinematics of a snail-crushing teiid lizard (Dracaena guianensis) with those in a closely related omnivorous species (Tupinambis merianae). Our data show that juvenile D. guianensis differ from T. merianae in having bigger heads and greater bite forces. Adults, however, do not differ in bite force. A comparison of feeding kinematics in adult Dracaena and Tupinambis revealed that Dracaena typically use more transport cycles, yet are more agile in manipulating snails. During transport, the tongue plays an important role in manipulating and expelling shell fragments before swallowing. Although Dracaena is slow, these animals are very effective in crushing and processing hard-shelled prey. J. Exp. Zool. 317A:371381, 2012. (c) 2012 Wiley Periodicals, Inc.

A specialized genetic algorithm to solve the short term transmission network expansion planning

In this paper, the short term transmission network expansion planning (STTNEP) is solved through a specialized genetic algorithm (SGA). A complete AC model of the transmission network is used, which permits the formulation of an integrated power system transmission network expansion planning problem (real and reactive power planning). The characteristics of the proposed SGA to solve the STTNEP problem are detailed and an interior point method is employed to solve nonlinear programming problems during the solution steps of the SGA. Results of tests carried out with two electrical energy systems show the capabilities of the SGA and also the viability of using the AC model to solve the STTNEP problem. © 2009 IEEE.

Specialized genetic algorithm for transmission network expansion planning considering reliability

This paper presents a methodology to solve the transmission network expansion planning problem (TNEP) considering reliability and uncertainty in the demand. The proposed methodology provides an optimal expansion plan that allows the power system to operate adequately with an acceptable level of reliability and in an enviroment with uncertainness. The reliability criterion limits the expected value of the reliability index (LOLE - Loss Of Load Expectation) of the expanded system. The reliability is evaluated for the transmission system using an analytical technique based in enumeration. The mathematical model is solved, in a efficient way, using a specialized genetic algorithm of Chu-Beasley modified. Detailed results from an illustrative example are presented and discussed. © 2009 IEEE.

Purpose. The purpose of this study was to evaluate the discrepancies between abstracts presented at the IADR meeting (2004-2005) and their full-text publication. Material and Methods. Abstracts from the Prosthodontic Section of IADR meeting were obtained. The following information was collected: abstract title, number of authors, study design, statistical analysis, outcome, and funding source. PubMed was used to identify the full-text publication of the abstracts. The discrepancies between the abstract and the full-text publication were examined, categorized as major and minor discrepancies, and quantified. The data were collected and analyzed using descriptive analysis. Frequency and percentage of major and minor discrepancies were calculated. Results. A total of 109 (95.6%) articles showed changes from their abstracts. Seventy-four (65.0%) and 105 (92.0%) publications had at least one major and one minor discrepancies, respectively. Minor discrepancies were more prevalent (92.0%) than major discrepancies (65.0%). The most common minor discrepancy was observed in the title (80.7%), and most common major discrepancies were seen in results (48.2%). Conclusion. Minor discrepancies were more prevalent than major discrepancies. The data presented in this study may be useful to establish a more comprehensive structured abstract requirement for future meetings. © 2012 Soni Prasad et al.
