Accuracy of Rapid Prototyping Biomodels Plotted by Three Dimensional Printing Technique: Ex Vivo Study  [PDF]
Lucio Costa Safira, Luana Costa Bastos, Valter Estevo Beal, Roberto Almeida de Azevedo, Carlos Eduardo Francischone, Viviane Almeida Sarmento
Advances in Computed Tomography (ACT) , 2013, DOI: 10.4236/act.2013.22008
Abstract: The rapid prototyping biomodels manufacturing is a recent technology with great importance in oral and maxillofacial surgery. It provides a better surgical planning, decrease of anesthesia time and great functional and esthetic results. The aim of this experimental study was to evaluate the accuracy of rapid prototyping biomodels built by three-dimensional printing (3DP) technique, since this is one of the least expensive methods available. Linear measurements of standardized bone defects and anatomic distances were compared using a digital caliper of high precision in nine dry mandibles (gold standard) and their respective biomodels. The Bland-Altman test was used for statistical analysis (5% level of significance). The results showed strong concordance between the dry mandibles and their respective biomodels, with discrepancies smaller than 2 mmin most cases (97.4%). We can conclude that the biomodels built by 3DP technique can be used for surgical planning in Dentistry.
Do Tsihuri ao Waradzu: o que as ideologias xavante de concep??o, substancia e forma??o da pessoa nos dizem sobre o estatuto ontológico do outro?
Fernandes, Estevo Rafael;
Horizontes Antropológicos , 2010, DOI: 10.1590/S0104-71832010000200019
Abstract: this work reflects about the notions of conception, substance and personhood among the the shavante indians (and between the gê indians, in general) and its perception of the other. what i try to demonstrate is that such notions, although it seems to, are not static, but extremely dynamic - being that such dynamism reflects an ideology of inclusive perception of this "other", beyond bodiness, but also in its mythology, history and in the contact with the whites.
Low-cost microprocessed instrument for evaluating soil temperature profile
CRUVINEL, PAULO ESTEVO;
Pesquisa Agropecuária Brasileira , 2000, DOI: 10.1590/S0100-204X2000001100020
Abstract: this paper describes a low-cost microprocessed instrument for in situ evaluating soil temperature profile ranging from -20.0°c to 99.9°c, and recording soil temperature data at eight depths from 2 to 128 cm. of great importance in agriculture, soil temperature affects plant growth directly, and nutrient uptake as well as indirectly in soil water and gas flow, soil structure and nutrient availability. the developed instrument has potential applications in the soil science, when temperature monitoring is required. results show that the instrument with its individual sensors guarantees ±0.25°c accuracy and 0.1°c resolution, making possible localized management changes within decision support systems. the instrument, based on complementary metal oxide semiconductor devices as well as thermocouples, operates in either automatic or non-automatic mode.
Fiat voluntas tua! Vício e pecado na ética de Abelardo
Estevo, José Carlos;
Trans/Form/A??o , 1989, DOI: 10.1590/S0101-31731989000100007
Abstract: abelardo, na sua ética, desqualifica a no??o de "vício" em favor da no??o de "pecado". esta passagem n?o é apenas um pressuposto do autor, mas decorre necessariamente tanto de sua posi??o enquanto lógico quanto de sua crítica dos filósofos estóicos que p?de conhecer.

ética e rela??es internacionais: elementos de uma agenda político-cultural
Martins, Estevo de Rezende;
Revista Brasileira de Política Internacional , 2001, DOI: 10.1590/S0034-73292001000200001
Abstract: the international relations began to reflect more intensively since the 1990s the requirement of moralization of the public sphere. the theme of ethics - often present on the internal political agendas - gets into the action programs of multilateral organizations and becomes strongly requested from public agents. on the internal and external field as well the contemporary ethical agenda takes the human rights as its substantial reference, as the leading values for a valuable private and public behavior, including the international organizations. for such a historical trend some examples may be mentioned: the internal and external brazilian policy on human rights, the organizing tendency of the regional blocks, as the european union, and the "social clause" considered as indispensable to the economic, commercial and financial relations.
O alargamento da Uni?o Européia e a América Latina
Martins, Estevo de Rezende;
Revista Brasileira de Política Internacional , 2004, DOI: 10.1590/S0034-73292004000200001
Abstract: the european union's expansion in 2004 owing to the unprecedented adhesion of ten countries simultaneously signaled a movement toward endogenous concentration based on intra-european means and efforts. this expansion entails further difficulties for eu's external relations, including those with latin america. the cultural legacy partially shared by europe and countries such as the latin american countries is insufficient to change current economic and trade relations. a further obstacle is the political and conceptual inconsistency of a "latin america" that is neither an interlocutor nor a natural partner. the eu's political initiatives and their possible outcome do not go beyond affable rhetoric and good intentions or are restricted to development aid. owing to their competing interests in bilateral or multilateral relations, the european union and its member countries prefer to deal with similar blocs, such as mercosur or the andean community, which have a more clearly defined profile.
História, discurso e estrutura
Estevo de Resende Martins
Diálogos , 2010, DOI: 10.4025/dialogos.v12i1.29
Abstract: O recurso categorial à no o de estrutura, nas suas diversas rela es, pode ser de validade metódica para a elabora o da explica o histórica mas n o permite deduzir que a história mesma (como a suma de todos os atos humanos efetivamente praticados) se petrificasse numa numa estrutura (ou em mais de uma) mesmo se apenas discursiva. The categorical recourse to the notion of structure, in its many relations, can be methodologically useful in elaborating a historical explanation, but does allow us to deduce that history itself (as the sum of all human acts actually practiced) would solidify itself in a single (or more than one) structure, even if only a discursive on. El recurso de categorizar la noción de estructura, en sus diversas relaciones, puede tener validez metódica para la elaboración de la explicación histórica; sin embargo, no permite deducir que la propia historia (entendida como la suma de todos los actos humanos efectivamente practicados) se petrificara en una estructura (o en más de una), aún siendo sólo discursiva.
História: consciência, pensamento, cultura, ensino
Martins, Estevo C. de Rezende;
Educar em Revista , 2011, DOI: 10.1590/S0104-40602011000500004
Abstract: history is made by human action in time and in the social space. any action is individual. its results exceed, in most cases, the private scope of a person, and moreover shape the society as a whole, in different ways. the teaching of history is located in a double perspective. the traditional one more restricted to certain individuals and groups, and another one, far more comprehensive, which influences beyond the present time and the present society. in both cases it is required that each individual develops historical consciousness, which puts into perspective the reflected experience of time, whose sense of history comes to be articulated only when there is a proper identification of its components and its cultural effects. the teaching of history finds its most prominent role in the establishment of substantive correlation between the daily life of present and the historicized past. it must preserve the quality of the contents produced and control its responsible use by teachers and students in the common social and cultural life. the teaching of history is, thus, both profession and mission.
In silico analysis of Eucalyptus thioredoxins
Barbosa, Aulus Estevo;Marinho, Paulo;
Genetics and Molecular Biology , 2005, DOI: 10.1590/S1415-47572005000400008
Abstract: the eucalyptus genome sequencing project (forests), an initiative from the brazilian onsa consortium (organization for nucleotide sequencing and analysis), has achieved the sequencing of 123.889 est clones from 18 different cdna libraries. we have investigated the forests data set to identify est clusters potentially encoding thioredoxins (trx). two types of thioredoxin families described in plants, chloroplastic (trxm/f/x/y) and cytosolic (trxh), have been found in the transcriptome. putative typical trxs have been identified in fifteen clusters, four m-type, seven h-type, two f-type, one cluster for each x/y-types and one putative homologue of the tdx gene from arabidopsis thaliana. one cluster presents an atypical active site wcmps, different from the conserved wcgpc present in the other 15 clusters, and corresponds to a subgroup of cytosolic thioredoxins. except in specific libraries from callus, roots, seedlings and wood tissues, thioredoxin deduced ests are found in all remaining libraries. according to the calculated frequencies of ests, chloroplastic thioredoxins are preferentially present in green tissues such as leaves whilst cytoplasmic thioredoxins are more general but demonstrate elevated frequencies in seedlings and flower tissues. trx frequency patterns in the eucalyptus transcriptome seem to indicate a good coherence with data from arabidopsis thaliana gene expression.
