A Closed-Form Solution of a Kinetic Integral Equation for Rarefied Gas Flow in a Cylindrical Duct  [PDF]
Carmo Henrique Kamphorst, Patricia Rodrigues, Liliane Basso Barichello
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.510145
Abstract:

A spectral method based on Hermite cubic splines expansions combined with a collocation scheme is used to develop a solution for the vector form integral S-model kinetic equation describing rarefied gas flows in cylindrical geometry. Some manipulations are made to facilitate the computational treatment of the singularities inherent to the kernel. Numerical results for the simulation of flows generated by pressure and thermal gradients, Poiseuille and thermal-creep problems, are presented.

Acta Scientiarum : Education , 2011,
Abstract: Esta produ o intelectual persegue a busca da maior compreens o acerca das quest es que perpassam o cenário educacional, mais especificamente as práticas de qualidade na Educa o Infantil. Fazem-se necessárias investiga es, para que se compreenda o desejo de governamento e de qualidade na Educa o Infantil e, ao mesmo tempo, as práticas pedagógicas de qualidade e de controle que ocorrem nos espa os escolares. As práticas educativas de qualidade s o percebidas dentro deste ambito de rela es de poder governamental. A qualidade n o se faz entender como o desejo e a necessidade de cada sujeito dentro de seu contexto social e cultural, mas sim, dentro de uma perspectiva de anseios políticos, econ micos, sociais e culturais generalizados, que resulta em uma unifica o do que se acopla como qualidade educativa nacional. Dessa forma, tem-se como objetivo investigar a legisla o e outros referenciais teóricos, os ambientes escolares e como se dá a qualidade nas práticas normativas de educa o em nível de Educa o Infantil, para compreender como acontece a normaliza o e o controle escolar pelo viés do governamento. This intellectual production pursues a greater understanding of the issues that pervade the educational scene, especially the quality practices in early childhood education. Investigations are necessary to understand the desire for governance and quality in childhood education, as well as teaching practices of quality and control that occur in school spaces. Quality educational practices are perceived within this framework of government power relations. Quality is not understood as the desire and need of each subject within their social and cultural context, but rather within a perspective of widespread political, economic, social and cultural desires, resulting in a unification that attaches to national educational quality. Thus, the objective is to investigate the legislation and other theoretical frameworks, the school environment and how quality of education plays out in regulatory practices at the kindergarten level, to understand how standardization and school control through governance takes place.

Abstract: objectives: to evaluate the intensity of pain in patients after cardiac surgery; the study aimed to: 1- identify possible associations between physiological alterations (tachycardia, tachypnea, increased blood pressure, sweating, paleness, nausea and vomiting) and postoperative pain, and 2- describe the used analgesia. methods: this prospective study evaluated 30 patients in a public teaching hospital, from the immediately postoperative period till the 4th postoperative day. to analyze the data was used the software statistical package for social sciences. results: most (26/86.7%) patients had pain, being 19 (63.3%) in the 1st postoperative day. it was found a predominance of mild pain during all occasions of evaluation. also was found a correlation (p<0.001) between pain and the presence of physiological alterations, most frequently, tachypnea and increased blood pressure. the analgesia was treated with drugs, being the opiates and simple analgesics the most prescribed. conclusion: a mild pain was present during all periods which influenced mainly the occurrence of tachypnea and high blood pressure. only drugs were used for analgesia.
Population ecology of two woodland caribou herds in the southern Yukon

Rangifer , 1996,
Abstract: Since the mid 1980's, the Aishihik herd of woodland caribou (Rangifer tarandus caribou) declined from approximately 1500 to 583 animals. During the same period a nearby herd, the Wolf Lake Herd increased from approximately 664 to 1249 animals. This paper compares aspects of the ecology of these two herds to determine how these relationships conform to a general model of caribou population ecology described by Seip (1992). Comparisons include caribou demographic characteristics and distribution patterns, predator densities, abundance of alternate prey, human hunting and snow depth on caribou winter range. Ecological differences between herds were apparent in the ratio of prime bulls to cows, the abundance of moose (Alces alces), the occurrence of coyotes (Canis latrans), late winter snow conditions, and access to hunting. We hypothesize that the Wolf Lake herd was able to grow because wolves {Canis lupus) preyed mainly on the relatively abundant moose population. A highly clumped winter caribou distribution may have further reduced the impact of wolf predation on the Wolf Lake herd. In contrast, the decline of the Aishihik herd was accompanied by a relative scarcity of moose, few prime aged caribou bulls probably due to a more liberal trophy harvest, and wider late-winter dispersion that offered wolves greater access to caribou. The decline may have been exaggerated by the peak in the snowshoe hare (Lepus americanus) cycle which may have temporarily improved wolf pup survival. We suspect that moose are normally the primary prey of wolves in the Yukon and that a decline in moose eventually results in their being too scarce to offer an economical prey choice, prompting a prey switch to caribou. Results of our analyses conform incompletely to Seip's (1992) model for woodland caribou population ecology, particularly because the Wolf Lake herd prospered where moose were relatively abundant.

Scientia Iuris , 2007,
Abstract: The role of State in preserving the environment has revealed to be essential, seen that by interfering in economic activities it can establish the minimal regulation to be observed by society. Among the economic instruments employed by the modern State to protect environment it is the establishment of taxing, which constitutes source of profit from public means used in the financial activity and that can be employed either in its fiscal and extrafiscal aspect. Thus, the study contemplates a reflection upon Environmental taxation, delimitating in the ways of a form to protecting environment. A atua o do Estado na preserva o do meio ambiente tem se revelado imprescindível, pois mediante sua interven o nas atividades econ micas ele pode estabelecer regras mínimas a serem observadas pela sociedade. Dentre os instrumentos econ micos usados pelo Estado moderno para a preserva o do meio ambiente está o tributo, que constitui fonte de receita pública empregada na atividade financeira e pode ser utilizado tanto em seu aspecto fiscal quanto em seu aspecto extrafiscal. Diante deste contexto, o estudo contempla uma reflex o sobre a Tributa o Ambiental, tendo como delimita o o tributo extrafiscal como forma de prote o do meio ambiente.
