Estimativa do fluxo de calor e da difusividade térmica do solo, baseado na solução da derivada temporal fracionária de meia ordem em ferramenta de software

The soil heat flux and soil thermal diffusivity are important components of the surface energy balance, especially in ar id and semi-arid regions. The obj ective of this work was to carry out to estimate the soil heat flux from th e soil temperature measured at a single depth, based on the half-order time derivative met hod proposed by Wang and Bras (1999), and to establish a method capable of es timating the thermal diffusivity of the soil, based on the half order derivative, from the temporal series of soil temperature at two depths. The results obtained in the estimates of soil heat flux were compared with the values of soil heat flux measured through flux plates, and the thermal di ffusivity estimated was compared with the measurements carried out in situ. The results obtained showed excellent concordance between the estimated and measured soil heat flux, with correlation (r), coeffici ent of determination (R 2 ) and standard error (W/m 2 ) of: r = 0.99093, R 2 = 0.98194 and error = 2.56 (W/m 2 ) for estimated period of 10 days; r = 0,99069, R 2 = 0,98147 and error = 2.59 (W/m 2 ) for estimated period of 30 days; and r = 0,98974, R 2 = 0,97958 and error = 2.77 (W/m 2 ) for estimated period of 120 days. The values of thermal di ffusivity estimated by the proposed method showed to be coherent and consis tent with in situ measured va lues, and with the values found in the literature usi ng conventional methods.

Das palavras à vida: o prazer em Max Weber

The thesis has as its goal the discussion over the pleasure as an intellectual and personal subject for Max Weber. The main references are The Sociology of Religion, Science as a Vocation and Politics as a Vocation, Bureaucracy, The sense of "Axiological Neutrality" in Social and Economic Sciences. Many authors were researched for information about his life, with a highlight to the biography written by his wife Marianne Weber, for its great number of excerpts from letters and informal conversations. The subject "pleasure" was developed by taking into consideration the complexity of this phenomenon which happens in an ambivalent and multiple ways. In order to do that, we started from the paradigm of the complexity according to Edgar Morin's view, Georges Bataille's discussions on erotism and the antinomic comprehension of Lepegneur and Onfray, who define pleasure as a phenomenon with ambiguities, and the historical references of Peter Gay, Nobert Elias, Wolf Lepenies. In Max Weber, pleasure presents, also, this ambiguity, as his scientific approach is registering the absence of pleasure for the rise of a protestant ethic and, besides that, to support with a process of disenchantment of the world which leads us to a meaningless life. Weber goes through great changes in the last years of his life. In this period he includes in his comments the subjects "erotism" and "arts" with the possibility of escaping from modem everyday routine that affects the individual's existential freedom. However, his ambiguous position about these possibilities take him to consider that a situation o f personal confrontation, considered heroical, once, in his opinion, each one accepts the consequences o f their acts and builds their values to give a meaning to their own existence. The pleasure in Weber is, above ali aspects, intellectual and existential: side by side with the routine, bureaucracy and disenchantment ofthe world was the possibility of charisma, vocation and passion. However, always he related these characteristics to the discomfort that the modem world presented to men, he, as a scientist, was ethical. This is the main argument ofthis thesis

Regime jurídico dos incentivos fiscais: uma análise à luz da ordem econômica

This scientific investigation begins with the recognition of the authorization granted by the Constitutional Legislator to the State for, relativizing its neutrality towards the private sector, intervene in the behavior of economic agents, through different means, including fiscal incentives and tax increases in order to achieve the objectives and directives of the Federal Constitution, as well as achieve the rights and guarantees also described in the Federal Constitution. Demonstrates, however, that this intervention in the private sector has the power to generate both salutary reflections as perverse and divorced goals from what was established by the Federal Constitution and Multilateral Agreements and this is the basis that justifies the relevance of the study: because of the urgency to provide a thorough analysis of the phenomenon of state intervention in the Economic Order, given the importance of its impacts, both for citizens' lives, as well as for the maintenance of the State established as it is nowadays. From this premise, this research examines the issue of tax policies adopted in the country, focusing on tax incentives, comparing its use with the principles of the Economic Order and the General Agreement on Tariffs and Trade - GATT analyzing whether these have been respected or if Brazil adopted unjustified protectionist measures. From this context, this research approximated different branches of the law, developed through literature review in areas such as constitutional law, economic law, tax law, financial law and law and economics. This study verifies the motivations and objectives that underlie the adopted justifications for the use of tax incentives, as well as its results, seeking to empirically answer if its use is reasonable and consistent with the terms enshrined in the Federal Constitution of 1988 and GATT. The answer to this research question will be sought through doctrinal analysis, jurisprudence and hard cases. Thus, the study begins with the historical evolution of extrafiscality, analyzes the principles that should guide the behavior of economic agents. Subsequently analyzes the legal regime of tax incentives and the results achieved by hard cases in which the tax policies with extrafiscal nature were adopted in order to demonstrate the positive and negative consequences arising from the adoption of this type of benefit

O sonhador de palavras: poética cênica em "Vau da Sarapalha"

In this article we look at the symbolic plot present in the theatrical adaptation of the short story Sarapalha and also at the director’s creative process. We aim at highlighting the element which, according to our hypothesis, worked as the convergence point between the two languages: fire

Perguntou o juiz ao tutor pela pessoa deste órfão: os magistrados na ordem sócio educacional do Seridó (século XIX)

This work has the objective to analyze the presence of justice, embodied in the orphans of judges, the encouragement, guidance and custody of minor heirs of the Village of Currais Novos, the area called Seridó of Rio Grande do Norte, especially with regard to education in the century XIX. Aims the meaning of the performance of judges in education and their practices, whereas this figure had a power that went beyond its mere function, but played a political role, taking responsibility for guarding and protection of property left by families of the Imperial period. The study focuses on the set of notary offices documents, inventories, sharing, self accounts and orders, belonging to the District of Currais Novos Forum in the period between the years 1822 to 1829. Finally, the conclusion demonstrates how Judges controlled the education of orphans, through tutors, and it is used for this purpose, the account acts as a procedural mechanism and documentary of its judicial activity.

Sobre projetos, palavras e imagens: relacionando textos e desenhos nos trabalhos finais de graduação em arquitetura e urbanismo

This research continues the current debate about the role of the images and the words in the architectural design persuasion, where we emphasize the increasing valuation of written documents (FORTY, 2004; MARKUS; CAMERON, 2002), the seduction for the graphical representation (DURAND, 2003) and the rhetorical effects of the graphical and textual resources (TOSTRUP, 1999). Based on these quarrels, we look for verify in the graduate final projects the relation between the design texts and images. From the PROJEDATA, database of the PROJETAR research group (UFRN), we selected the final projects of two brazilians universities, UFRN and USP, that in a first analysis, they had shown as ideal types of two distinct design presentation models, respectively: texts and drawings in separated documents, or combined in an only support. Based on Markus explanation about the function and the content of the texts, on the Durand perspective with regard to graphical representation uses and on Tostrup point of view concerning the rhetorical potential of texts and drawings, we analyze, in a set of 25 projects, how the students relate the textual and imagetical speeches. For this, we related the focus of each speech, in order to verify the possible coherence between both. We conclude that in the model of USP final project the coherence between the texts and the drawings is clearer than in the model adopted in UFRN
