ARTGEO: ensino interdisciplinar

The ARTGEO Project aimed at integrating science, art, and technology, emphasizing geometric elements which must be explored within the teaching process. Geometry, present in the most primitive civilizations, assists man in settling relationships and organizing his space. It has been clearly identified in human constructions, consisting of an important instrument of knowledge and domain of nature. The art, in its turn, can mediate the elaboration of knowledge, whether it is scientific, technical, or philosophical. Science and art are products that express the imaginary representations from distinct cultures. The Brazilian Concretism, for its relations with the geometry, is the period in art history chosen as reference. Technology was represented by the computational environments, as a didactic support and an instrument for the accomplishment of practical activities. Microsoft Word is one of the basic softwares for this proposal because of its easy access in most public schools.

Arte reversa: aplicando a engenharia reversa na arte

This study aimed to examine the reverse engineering and respond to a concern about the possible application of this concept in art, breaking down barriers and breaking paradigms. Using 3D scanning, the art of computer aided design and manufacturing – CAD/CAM, machining by computer numerical control - CNC, engineering, and applying this methodology in the arts especially in sculpture, it is possible to dematerialize a artwork, virtualizes it in 3D programs, make speeches, and process a new work, a new art elsewhere. By the example of surgeries at a distance, the artist, or technical author could produce their works, and materialize them anywhere. In other words, do the reverse gear. It discusses the relationship between art and technology, the role of the author, the viewer, which can interfere with the interactivity that case by stating that art, exists only in the look and feel of the viewer.

Whaling as Science

In an open letter published last year in the New York Times, 21 distinguished scientists (including three Nobel laureates) criticized Japan's program of scientific research whaling, noting its poor design and unjustified reliance upon lethal sampling. In a recent Forum article in BioScience, Aron, Burke, and Freeman (2002) castigate the letter's signers and accuse them of meddling in political issues without sufficient knowledge of the science involved in those issues.

Melting Alpine Glaciers Enrich High-Elevation Lakes with Reactive Nitrogen

Alpine glaciers have receded substantially over the last century in many regions of the world. Resulting changes in glacial runoff not only affect the hydrological cycle, but can also alter the physical (i.e., turbidity from glacial flour) and biogeochemical properties of downstream ecosystems. Here we compare nutrient concentrations, transparency gradients, algal biomass, and fossil diatom species richness in two sets of high-elevation lakes: those fed by snowpack melt alone (SF lakes) and those fed by both glacial and snowpack meltwaters (GSF lakes). We found that nitrate (NO3-) concentrations in the GSF lakes were 1-2 orders of magnitude higher than in SF lakes. Although nitrogen (N) limitation is common in alpine lakes, algal biomass was lower in highly N-enriched GSF lakes than in the N-poor SF lakes. Contrary to expectations, GSF lakes were more transparent than SF lakes to ultraviolet and equally transparent to photosynthetically active radiation.Sediment diatom assemblages had lower taxonomic richness in the GSF lakes, a feature that has persisted over the last century. Our results demonstrate that the presence of glaciers on alpine watersheds more strongly influences NO3- concentrations in high-elevation lake ecosystems than any other geomorphic or biogeographic characteristic.

Tropical, de Anita Malfatti

A partir da análise de Tropical, tela pintada por Anita Malfatti em 1917, este artigo propõe que a artista procedia a uma mudança em sua linguagem pictórica, afastando-se das concepções de vanguarda que adotara até então para, aderindo ao clima de retorno à ordem internacional, aproximar-se das discussões sobre o nacionalismo na arte, presentes na cena paulistana. Assim, a imagem de mulher insegura que mudou sua perspectiva por causa da crítica de Monteiro Lobato adquire outra conotação. Os modernistas teriam preferido essa interpretação a efetuar uma análise da obra de Anita Malfatti, por meio da qual se poderia desvelar uma deserção do programa vanguardista feita de forma consciente pela artista

Performance tests of two small trigeneration pilot plants

Trigeneration systems have been used with advantage in the last years in distributed electricity generation systems as a function of a growth of natural gas pipeline network distribution system, tax incentives, and energy regulation policies. Typically, a trigeneration system is used to produce electrical power simultaneously with supplying heating and cooling load by recovering the combustion products thermal power content that otherwise would be driven to atmosphere. Concerning that, two small scale trigeneration plants have been tested for overall efficiency evaluation and operational comparison. The first system is based on a 30 kW (ISO) natural gas powered microturbine, and the second one uses a 26 kW natural gas powered internal combustion engine coupled to an electrical generator as a prime mover. The stack gases from both machines were directed to a 17.6 kW ammonia-water absorption refrigeration chiller for producing chilled water first and next to a water heat recovery boiler in order to produce hot water. Experimental results are presented along with relevant system operational parameters for appropriate operation including natural gas consumption, net electrical and thermal power production, i.e., hot and cold water production rates, primary energy saving index, and the energy utilization factor over total and partial electrical load operational conditions.

Brazilian multicenter study on prevalence of preterm birth and associated factors

Abstract Background The occurrence of preterm birth remains a complex public health condition. It is considered the main cause of neonatal morbidity and mortality, resulting in a high likelihood of sequelae in surviving children. With variable incidence in several countries, it has grown markedly in the last decades. In Brazil, however, there are still difficulties to estimate its real occurrence. Therefore, it is essential to establish the prevalence and causes of this condition in order to propose prevention actions. This study intend to collect information from hospitals nationwide on the prevalence of preterm births, their associated socioeconomic and environmental factors, diagnostic and treatment methods resulting from causes such as spontaneous preterm labor, prelabor rupture of membranes, and therapeutic preterm birth, as well as neonatal results. Methods/Design This proposal is a multicenter cross-sectional study plus a nested case-control study, to be implemented in 27 reference obstetric centers in several regions of Brazil (North: 1; Northeast: 10; Central-west: 1; Southeast: 13; South: 2). For the cross sectional component, the participating centers should perform, during a period of six months, a prospective surveillance of all patients hospitalized to give birth, in order to identify preterm birth cases and their main causes. In the first three months of the study, an analysis of the factors associated with preterm birth will also be carried out, comparing women who have preterm birth with those who deliver at term. For the prevalence study, 37,000 births will be evaluated (at term and preterm), corresponding to approximately half the deliveries of all participating centers in 12 months. For the case-control study component, the estimated sample size is 1,055 women in each group (cases and controls). The total number of preterm births estimated to be followed in both components of the study is around 3,600. Data will be collected through a questionnaire all patients will answer after delivery. The data will then be encoded in an electronic form and sent online by internet to a central database. The data analysis will be carried out by subgroups according to gestational age at preterm birth, its probable causes, therapeutic management, and neonatal outcomes. Then, the respective rates, ratios and relative risks will be estimated for the possible predictors. Discussion These findings will provide information on preterm births in Brazil and their main social and biological risk factors, supporting health policies and the implementation of clinical trials on preterm birth prevention and treatment strategies, a condition with many physical and emotional consequences to children and their families.

Dos diagramas aos parâmetros: transformações no design digital

The article is part of an ongoing theoretical research about the emergence of parametric architecture. It discusses some of the last developments in digital design from the transition of the discourse and operativity by “diagrams” to the theories and processes derived from “parameters”. Centered in Peter Eisenman’s and Patrik Schumacher’s propositions, it is in its horizon to comprehend what relations are established between “diagram” and “parameter” -­‐ similarities, complementarities and differences -­‐, contributing for the critical contextualization of theoretical movements and design processes in contemporary architecture.

Coastline changes and sedimentation related with the opening of an artificial channel: The Valo Grande Delta, SE Brazil

The role played by human activity in coastline changes indicates a general tendency of retreating coasts, especially deltaic environments, as a result of the recent trend of sea level rise as well as the blockage of the transfer of sediments towards the coast, especially due to the construction of dams. This is particularly important in deltaic environments which are suffering a dramatic loss of area in the last decades. In contrast, in this paper, we report the origin and evolution of an anthropogenic delta, the Valo Grande delta, on the south-eastern Brazilian coast, whose origin is related to the opening of an artificial channel and the diversion of the main flow of the Ribeira de Iguape River. The methodology included the analysis of coastline changes, bathymetry and coring, which was used to determine the sedimentation rates and grain-size changes over time. The results allowed us to recognize the different facies of the anthropogenic delta and to establish its lateral and vertical depositional trends. Despite not being very frequent, anthropogenic deltas represent a favorable environment for the record of natural and anthropogenic changes in historical times and, thus, deserve more attention from researchers of different subjects

Gestión del ranking para una asociación canina de perros de exposición

[ES] Esta aplicación web realizada en Ruby on Rails, tiene como objetivo principal la gestión del ranking para una asociación de perros de exposición. Dicha asociación es la “Asociación Española para el Fomento de la Raza Bulldog Francés”. En dicha asociación, los perros participan en exposiciones caninas y de acuerdo con una tabla y los resultados, les adjudican puntos a los perros. La tabla de asignación de puntos puede variar cada año.  El perro que más puntos obtiene gana el ranking, hay un ganador hembra y otro ganador macho. Por otra parte, los posibles roles de usuarios son: el rol de administrador, los cuales pueden manejar todos los recursos; el rol de socio, que puede crear nuevos perfiles de perros, enviar resultados de sus perros y demás acciones posibles para este rol; el rol de usuarios registrado, que son usuarios que fueron socios y que ya no lo son. Dicho tipo de usuario puede modificar su perfil, pero ya no podría hacer cambios o eliminar sus perros de la aplicación. Y tampoco podría borrar resultados de sus perros que ya hubiesen sido enviados cuando era socio;  y el rol de usuario no registrado que sólo pueden ver los listados de perros, ver sus perfiles y demás acciones que sólo sean ver pero no crear, modificar ni borrar nada. Como resultado final a este trabajo de fin de grado se ha obtenido una aplicación con los requisitos necesarios para cubrir las necesidades para la asociación de perros de exposición, en el cual se gestiona el ranking, también se gestionan los perfiles tanto de perros como de usuarios, control de accesos según el rol del usuario, gestión de las exposiciones, etc.

Los objetos de aprendizaje en la enseñanza del vocabulario específico del inglés para la Conservación y Restauración

[ES]En la docencia de inglés del Grado en Conservación y Restauración de la Universidad de La Laguna (España), se ha constatado la inexistencia de recursos didácticos comerciales adecuados para este ámbito concreto, en particular para el aprendizaje del léxico especializado. Ante esta situación, como suele suceder en el campo del inglés para fines específicos, se ha acometido la creación gradual de materiales propios, empleando tecnologías de la información y de la comunicación (TIC). La experiencia acumulada durante los tres primeros años de andadura de la titulación, en los que los materiales TIC sirvieron de apoyo a la docencia presencial de grupos muy heterogéneos, ha conducido al planteamiento de la presente investigación.

La governance della società di capitale a base familiare: "Protocolo Familiar" e Patti di Famiglia

Family businesses have acquired a very specific gravity in the economy of occidental countries, generating most of the employment and the richness for the last ages. In Spain Family Businesses represent the 65% about the total of enterprises with 1,5 million companies. They give employment to 8 million people, the 80% of the private employment and develop the 65% of the Spanish GNP (Gross National Product). Otherwise, the family business needs a complete law regulation that gives satisfaction to their own necessities and challenges. These companies have to deal with national or international economic scene to assure their permanency and competitiveness. In fact, the statistics about family companies have a medium life of 35 years. European family businesses success their successor process between a 10 and 25%. It’s said: first generation makes, second generation stays, third generation distributes. In that sense, the Recommendation of the European Commission of December 7º 1994 about the succession of the small and medium companies has reformed European internal orders according to make easier successor process and to introduce practices of family companies’ good government. So, the Italian law, under the 14th Law, February 2006, has reformed its Covil Code, appearing a new concept, called “Patto di famiglia”, wich abolish the prohibition as laid dwon in the 458 article about successors’ agreements, admitting the possibility that testator guarantees the continuity of the company or of the family society, giving it, totally or in part, to one or various of its descendents. On other hand, Spain has promulgated the 17th Royal Decree (9th February 2007), that governs the publicity of family agreements (Protocolos familiars). These “protocolo familiar” (Family Agreement) are known as accord of wills, consented and accepted unanimously of all the family members and the company, taking into account recommendations and practices of family company’s good government.
