"Imperium in imperio". Il rapporto uomo-natura in Spinoza
Evangelista, Roberto
Laboratorio dell'ISPF , 2010,
Abstract: The relationship between man and nature denotes many problems in Spinoza’s context, where necessity plays an essential role. This essay tries to define the status of the possibility and its relationship to the natural necessity. The man-nature relationship reveals itself as conflictual space, where the human being faces the possibility of death and looks for the possibility of survival. The political action and the constitution of community offer an answer to the uncertainty of human position. Community is not an artificial monster; it is rather the adequate place where the human right and the human power express themselves. Nature and culture are not dissociated, since the society affirms the natural potentia of the human being and that of the multitude.

Multimedia Design and Transmedia Storytelling: Content Production for Microtrainings  [PDF]
Tércia Zavaglia Torres, Marcia Izabel Fugisawa Souza, José Ruy Porto de Carvalho, Silvio Roberto Medeiros Evangelista
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.623254
Abstract: This article presents an outline of model of the educational microcontent production for microtraining, built from the point of view that learning is a relational, intentional and experiential process, and, as such, it results from social interactions that also occur in labour spaces. The model, entitled “production cycle of pedagogical contents (microcontents)” is conceptually anchored in the theoretical precepts of transmedia storytelling and multimedia design, which in turn, are based in aspects of language, communication and cognition, bringing innovative elements capable of favouring leanings. In order to develop the model proposed and presented in the article, inherent conceptions to transmedia storytelling, multimedia design and education, are bound and articulated. Furthermore, one promotes the dialogue between non-formal education in the context of continuous formation and in the interest of technology transfer actions (TT) and of rural extension and technical assistance, for the formulation of microtraining activities via mobile devices. The essence of the model lies in the proposition of a sequence of steps that culminate in the production and organization of technological contents that incorporate pedagogical paths. Those paths serve as learnings favouring routes. It is accepted that this way of producing and organizing contents increases the chances of the subjects involved in the microtraining reflect upon and investigate their practices, abilities and experiences, thus helping them to resignify their realities and to build new rationalities to address their problems. The model “production cycle of pedagogical contents (microcontents)” was built to potentialize the chances of making microtrainings via mobile devices into massive actions that favour the TT process of Brazilian Agricultural Research Corporation (Embrapa), under a constructivist learning approach.
Comparison of diversity indices applied to macrophyte incidence-based data
Evangelista, Heloísa Beatriz Antoniazi;Thomaz, Sidinei Magela;Evangelista, Luiz Roberto;
Brazilian Archives of Biology and Technology , 2012, DOI: 10.1590/S1516-89132012000200014
Abstract: in this work, a recently proposed diversity index based on patil and taillie parametric diversity measure (or tsallis entropy), sq*, was applied to samples (presence-absence data) of macrophytes from the itaipu reservoir, brazil. this new index was the value of the family of indices sq for a specific evenness of a sample. results demonstrated that the shannon index and species richness showed expressively high correlation with the sq*; however, the evenness had low correlation coefficients with the index sq*, indicating that sq* was particularly sensitive to rarity and species richness. on the other hand, the weak correlations of this index with evenness demonstrated that it was less sensitive to species relative abundances.
A Poisson-Boltzmann Description for the Double-Layer Capacitance of an Electolytic Cell
Roberta Rarumy Ribeiro de Almeida,Luiz Roberto Evangelista,Giovanni Barbero
Physics , 2012,
Abstract: A Poisson-Boltzmann approach is used to determine the double-layer integral and differential capacitances in a finite-length situation for an electrolytic cell. By means of simple analytical calculations, it is shown how these quantities exhibit the bell-like and the camel-like shapes as a function of the applied voltage, when the thickness of the sample or the surface charge are varied. The problem is formulated treating the bulk liquid as a member of a grand canonical ensemble in contact with blocking electrodes. As a consequence, an applied voltage dependent Debye's screening length arises as a fundamental length governing the electrical behavior of the system.
The Kramers-Kronig relations for usual and anomalous Poisson-Nernst-Planck models
Luiz Roberto Evangelista,Ervin Kaminski Lenzi,Giovanni Barbero
Physics , 2013, DOI: 10.1088/0953-8984/25/46/465104
Abstract: The consistency of the frequency response predicted by a class of electrochemical impedance expressions is analytically checked by invoking the Kramers-Kronig (KK) relations. These expressions are obtained in the context of Poisson-Nernst-Planck usual (PNP) or anomalous (PNPA) diffusional models that satisfy Poisson's equation in a finite-length situation. The theoretical results, besides being successful in interpreting experimental data, are also shown to obey the KK relations when these relations are modified accordingly
Desempenho agron?mico e recomenda??es para cultivo de quinoa (brs syetetuba) no cerrado
Spehar, Carlos Roberto;Rocha, Juliana Evangelista da Silva;Santos, Roberto Lorena de Barros;
Pesquisa Agropecuária Tropical , 2011, DOI: 10.5216/pat.v41i1.9395
Abstract: quinoa (chenopodium quinoa willd.), native to the south american andes, has been adapted for cultivation in brazil, via progeny selection. originating from the q4 population, from ecuadorian valleys, q4.5 has shown outstanding performance. during the trials, it was standardized for agronomic traits and named brs syetetuba. in the summer and winter, it reached 2.3 t ha-1 and 7.5 t ha-1, respectively for grain and biomass yield, in 120 days, from emergence to maturity. these results were higher than those reached by the brs piabiru and kancolla check cultivars. the grains are saponin-free and have a mean weight of 2.9 g 1000-1. the results reveal that the brs syetetuba meets the desirable characteristics for commercial yield in brazil.
Aspectos clínico e cirúrgicos do tumor mamário canino: clinical and surgical evolution
Daleck, Carlos Roberto;Franceschini, Paulo Henrique;Alessi, Antonio Carlos;Santana, áureo Evangelista;Martins, Maria Izabel Mello;
Ciência Rural , 1998, DOI: 10.1590/S0103-84781998000100016
Abstract: mammary gland tumors in female dogs are among the most important neoplasia in dogs, deserving special attention regarding its diagnosis, treatment and prognosis. in this study, 23 biches of different breeds, from 8 to 11 years of age, with mammary tumors were evaluated. of the se, 12 were multiparous, 6 primiparous and 5 were nuliparous. all dogs came from the region of jaboticabal, sp and were referred to the veterinary teaching hospital of the fcavj-unesp. the animals were evaluated clinically and radiographically and the mammary mass submitted to an aspirative needle. a fragment of the tumor was also removed surgically for histopathological examination. most tumors were classified as carcinomas (52.17°/o), followed in number by mixed tumors (17.39%). treatment included mamectomy, partial mastectomy or "en bloc" mastectomy with removal of the lymphnodes. most dogs also received doxorubicin (20mg/m2) and cyclokphosphamide (100mg/m2) at, 7, 9 and 11 days post-operative. all dogs recovered uneventfully and at one year post-operative. twelve dogs were reevaluated an considered to be free of recurrence of metastasis.
Pozolanicidade dos resíduos industriais, l? de vidro e l? ceramica
Evangelista, Neuza;Tenório, Jorge Alberto Soares;Oliveira, José Roberto de;
Rem: Revista Escola de Minas , 2012, DOI: 10.1590/S0370-44672012000100011
Abstract: ceramic fibers are characterized by their light weight, high degree of purity, low heat storage, low thermal conductivity, thermal shock resistance and superior corrosion resistance in high-temperature environments. such characteristics make them ideal in the coating of distributors, mufflers, heating ovens, inter alia, as highly demanded by the mining and metallurgical industries, among others. after use in the process of industrial production, generated waste will lose its insulation capacity and thus requires disposal. the present work focuses specifically on ceramic and glass wools. due to the fact that ceramic fibers are aluminosilicate rich, we carried out an investigation relating to their pozzolanic activity with lime and cement, cpv ari, cpii e32 and cpiii 32rs specifically, aiming at an evaluation of their recycling prospect for incorporation into concrete.
Evaluation of thermal stress indexes for dairy cows in tropical regions
Silva, Roberto Gomes da;Morais, Débora Andréa Evangelista Fa?anha;Guilhermino, Magda Maria;
Revista Brasileira de Zootecnia , 2007, DOI: 10.1590/S1516-35982007000500028
Abstract: data from 359 holstein and 54 jersey cows (total of 1359 observations) collected in commercial herds in the northeast of brazil were used to evaluate six environmental stress indexes. the selection criterion was the correlation between the index value with the rectal temperature (rt) and the respiratory rate (rr) of cows. both temperature-humidity index (thi) and black globe-humidity index (bghi) had the lowest correlations with animal rt and rr. the selected indexes were the equivalent temperature index (r = 0.293 and 0.520 with rt and rr, respectively) and the heat load index (0.286 and 0.542, respectively).
