Borges Matias,Danilo; Gon?alves Alvim,Ricardo; Ribas,Mateus; Pierote de Oliveira,Bruno; Torres Chaves,Otto H.;
Actas Urológicas Espa?olas , 2009, DOI: 10.4321/S0210-48062009000600009
Abstract: objective: analyze technical details and results of laparoscopic treatment of ureterolithiasis. materials and methods: between january 2005 and august 2008 it was performed laparoscopic ureterolithotomy in 22 patients in our service. two (9%) by retroperitoneal access and 20 (91%) by transperitoneal access. mean size of the calculi was 15 mm. with a variation from 8 mm to 23 mm. the calculus were in the upper tract in 18 patients (81,8%) and in mid ureter in 4 patients (18,2), any of the calculus were in lower ureter. most of calculi were obstructive stones for more than 2 months. eight patients were submited a previous section of extracorporeal shockwave lithotripsy and 2 by extracorporeal shockwave lithotripsy plus ureterolithotripsy as a calculi treatment attempt. twelve patients had a laparoscopic ureterolithotomy as a primary indication for treatment. results: laparoscopic ureterolithotomy was successful for 20 patients (90,9%), and the fails occurred in the beginning of our experiment. mean operative time was 145 minutes with range from 70 to 240 minutes. the indwelling ureteral stent was used in 03 cases; 02 preoperative, and 01 postoperative. the ureteral suture was performed with absorbable 4.0 separated stitches in all patients. the global average of permanence in hospital was 3,3 days and the drain permanence was 7,2 days. the global complication rate was 13,6%. the global rate of stone free was 91%, and there were residual stone in 2 patients. conclusions: the laparoscopic treatment of ureterolithiasis besides minimally invasive, it is viable, secure and very effective. it should have taken into consideration as a procedure to extracorporeal shockwave lithotripsy and ureteroscopy. but, in cases where there are obstructive stones for a long time, in selected patients and, in special, in patients with just one kidney, it can be considered as a first line treatment. about the access, if retroperitoneal or transperitoneal; it is not still possible to affirm

Ciência e Agrotecnologia , 2011, DOI: 10.1590/S1413-70542011000300010
Abstract: syngonanthus mucugensis giul. subsp. mucugensis is an herbaceous plant with significant economic value in the ornamental dry flower business. the restricted occurrence of the municipality mucugê-ba, brazil, exclusively associated with extractive exploitation, has considered this species as endangered. the objective of this work was to evaluate the organogenic potential of three different types of s. mucugensis subsp. mucugensis explants to promote the development of an alternative method to the propagation of the genetic resources of this important plant. the morphogenetic capacities of the leaf, stem and root this species was tested using murashige and skoog culture medium at half salt concentration and different concentrations of growth of regulators benzylaminopurine - bap (0.00; 2.22 and 4.44 μm), and naphthalene acetic acid - naa (0.00; 1.34 and 2.68 μm). the morphoanatomic events that lead to formation of shoots were described. stems proved to be the best source of explants, showing 58.75% regeneration of shoot by direct organogenesis in the absence of growth regulators, and 32.18 and 47.55% of shoot regeneration by indirect organogenesis in the presence of 2.22 and 4.44 μm bap, respectively. as for leaves, there was callus formation, but without regenerating shoots. morphogenesis was not observed when roots were used as explants. the histological analyses showed that shoot regeneration in s. mucugensis subsp. mucugensis occurred both indirectly, by unorganized tissue differentiation, and directly through returning to merismatic activity in differentiated mature cells and preexisting bud proliferation.

Abstract: A comercializa o de certificados de redu o de emiss o através dos mercados de carbono vem servindo como um instrumento alternativo para a mitiga o do aquecimento global e das mudan as climáticas, que amea am a sobrevivência da humanidade no planeta. Este trabalho objetivou apresentar o cenário atual da comercializa o de créditos de carbono e suas rela es com aspectos econ micos e sociais através de um levantamento de dados encontrados na literatura existente. O aumento dos níveis de emiss o de gases de efeito estufa nos últimos anos é preocupante, apesar dos esfor os tomados pelas principais economias. é necessário um maior consenso entre as na es, além de uma regulamenta o adequada que permita uma maior participa o de agentes interessados, para que o problema do aquecimento global n o chegue a uma condi o irreparável. The trading of certified emission reduction through carbon markets is proving a very effective tool for mitigating global warming and climate change, that threatening the survival of humanity on the planet. This study aimed to present the current picture of the marketing of carbon credits and their relationship to economic and social aspects through a survey of data found in literature. The increase in emission levels of greenhouse gases in recent years is worrying, despite the efforts taken by major economies. It is necessary a greater consensus among nations, and an appropriate regulation to allow greater participation of stakeholders, so that the problem of global warming does not get an irreparable condition.

The evolution of social media in the recent years promoted the appearance of a new category: social media based on check-in. It enables the user to define their identity through information sharing. This paper aims to show the evolution of these media highlighting the effects and changes they cause in society through Super Bowl XLVI scenario, besides indicating the important role they have for the companies and marketing.

Complex cobordism and embeddability of CR-manifolds
Bruno De Oliveira
Mathematics , 2001,
Abstract: This paper studies complex cobordisms between compact, three dimensional, strictly pseudoconvex Cauchy-Riemann manifolds. Suppose the complex cobordism is given by a complex 2-manifold X with one pseudoconvex and one pseudoconcave end. We answer the following questions. What is the relation between the embeddability of the pseudoconvex end and the embeddability of the pseudoconcave end of X? Do all CR-functions on the pseudoconvex end of X extend to holomorphic functions on the interior of X? We prove that embeddability of a strictly pseudoconvex Cauchy-Riemann 3-manifold is not a complex-cobordism invariant. We show that a new phenomenon occurs: there are CR-functions on the pseudoconvex end that do not extend to holomorphic functions on X. We also show that the extendability of the CR-functions from the pseudoconvex end is necessary but not sufficient for embeddability to be preserved under complex cobordisms.

Abstract: The knowledge of animal behavior under grazing in different biomes is an alternative to increase production because it identifies possibilities of strategic interventions in the management. The aim of this study was to evaluate if the average time of grazing, ruminating and leisure are related to the position (station/decubitus), to the location (sun or shade), as well as the influence of gender in these interactions in Santa Inês sheep in Cerrado from Federal District, Brazil. To obtain the data, the behavior of the animals was assessed by visual observations at ten-minute intervals over a period of ten hours on two consecutive days. From the data obtained were analysis of variance and comparisons between means by Tukey test with significance level of 5%. The result of this study showed that the average time of grazing, ruminating and leisure in Santa Inês sheep, are related to the position (station/decubitus) and location (sun and shade). No significant differences were identified in relation to time spent in the activity of grazing, ruminating and leisure between Santa Inês sheep males and females. O conhecimento do comportamento animal sob pastejo em diferentes biomas é uma alternativa para o incremento na produ o, pois identifica possibilidades de interven es estratégicas no manejo. O objetivo do presente trabalho foi avaliar se o tempo médio de pastejo, rumina o e ócio est o relacionados com a posi o (esta o/decúbito), com o local (sob sol ou sombra), bem como a influência do sexo nestas intera es em ovinos da ra a Santa Inês no bioma Cerrado do Distrito Federal. Para a obten o dos dados, o comportamento dos animais foi avaliado por observa es visuais em intervalos de dez minutos num período de dez horas, em dois dias consecutivos. A partir dos dados obtidos foram realizadas as análises de variancia e compara es entre as médias pelo teste de Tukey com nível de significancia de 5%. O resultado deste estudo permitiu concluir que os tempos médios de pastejo, rumina o e ócio nos ovinos da ra a Santa Inês, est o relacionados com a posi o e o local. N o foram identificadas diferen as significativas em rela o ao tempo gasto na atividade de pastejo, rumina o e ócio entre machos e fêmeas.

Vis es do apocalipse anglo-sax o na
Ricardo da Costa,Bruno Oliveira
Brathair , 2001,
Abstract: This article analyses the work British Destruction of the British monk Gildas, written in the 540 years AD. We brought out the passages that the author advises the British chiefs to supplant their weaknesses and their governmental incapacities due to their vices. To Gildas this chiefs were tyrants and the main responsible for the British defeat from the invasions. We also brought out the critics that Gildas made of the clerics of his time, probably influenced by the Irish monkship.To complete the historical research we took one work of Tacito (Life of Julio Agrícola), Beda (Historical Works), Nennius (History of Britons) and The Anglo Saxon Chronicle, written in the time of the king Alfred, the Great. The article is divided in six parts: the common characteristics of the German kingdoms, the invasion of the Britain – with a brief description of the Germanic migrations and the settlement of the Angles, Saxons and Juts, the new social structures – specially the changing of the Sippe, the Christianisation of England – with the return of the paganism and the works of conversion of Augustine, and a brief biography of Gildas.
