S O GON ALO, DIVIS O DO TRABALHO NA METRóPOLE E A FORMA O DA NOVA PERIFERIA METROPOLITANA
Daniel Pereira Rosa
Revista Tamoios , 2010,
Abstract: Neste artigo refletimos sobre as mudan as ocorridas no espa o de S o Gon alo (RJ) e discutimos as proje es para o projeto de cidade em curso em um momento em que devido a fatores como a reestrutura o produtiva, a maior seletividade do capital, somados à uma mudan a de perfil do habitante gon alense, nota-se uma organiza o do espa o que atenda à uma maior fatia da popula o tornadas consumidoras de produtos imobiliários e bens de consumo n o –duráveis. Pensamos ent o nas causas e conseqüências desta mudan a do que chamamos de Nova Periferia Metropolitana para acentuar a diferen a deste espa o, com o conceito outrora adotado de que os municípios da periferia metropolitana fluminense cumpriam apenas o papel de reserva de m o-de-obra n o qualificada para a cidade do Rio de Janeiro e para a antiga capital fluminense, Niterói. Fato é que a cidade de S o Gon alo ainda enfrenta desafios para que o espa o seja promotor de melhorias sociais sobretudo em um momento em que ‘cidadania’ é cada vez mais forjada enquanto consumo.N o negamos a condi o periférica mas através da hierarquia urbana, do planejamento citadino e dos novos empreendimentos, buscamos elementos para análise do que significado destas mudan as nitidamente em curso.
Indium-Carrier Minerals in Polymetallic Sulphide Ore Deposits: A Crystal Chemical Insight into an Indium Binding State Supported by X-ray Absorption Spectroscopy Data

Minerals , 2012, DOI: 10.3390/min2040426
Abstract: Indium is a typical chalcophile element of the Earth’s crust, with a very low average content that seldom forms specific minerals, occurring mainly as dispersed in polymetallic sulphides. Indium recovery is based primarily on zinc extraction from sphalerite, the prototype of so-called tetrahedral sulphides, wherein metal ions fill half of the available tetrahedral sites within the cubic closest packing of sulphur anions, leaving interstices accessible for further in-filling. Ascertaining the tendency towards the establishment of In-In interactions through an x-ray absorption spectroscopy approach would efficiently contribute to understanding the behavior of indium in the carrier mineral. The successful results of applying such a near-edge absorption (XANES) study at In L 3-edge to samples collected at the Lagoa Salgada polymetallic orebody in the Iberian Pyrite Belt (IPB) are described and the crystal chemistry of indium is re-evaluated, disclosing a potential clue for the metal binding state in polymetallic sulphides.

Abstract: O experimento foi realizado na Embrapa Arroz e Feij o, com o objetivo de avaliar a produ o de matéria seca e composi o bromatológica da Brachiaria brizantha cv. Marandu. O trabalho foi desenvolvido em um Latossolo Vermelho Escuro de média fertilidade. Esta área era ocupada por lavouras anuais, corrigida esporadicamente e adubada anualmente. Inicialmente, esta ficou em repouso por um período de um ano, onde desenvolveu a Brachiaria brizantha. A área total ocupada era de 16 hectares, sendo dividida em cinco piquetes de 3,2 ha. O pasto foi ro ado para uniformiza o da pastagem. Foram colocados 34 animais, onde se utilizou o sistema rotacionado com 32 dias de descanso e oito dias de ocupa o. A forrageira era amostrada semanalmente antes da entrada dos animais nos piquetes, para o acompanhamento da produ o de matéria seca e composi o bromatológica. As baixas temperaturas e a falta de umidade do solo foram os fatores que mais influenciaram na produtividade e qualidade da Brachiaria brizantha cv. Marandu. PALAVRAS-CHAVE: Coleta de amostra, manejo de pastagem, pastejo rotacionado, qualidade da pastagem.

Revista Brasileira de Ortopedia , 2008, DOI: 10.1590/S0102-36162008000700003
Abstract: objective: to evaluate the effectiveness of ganz clamp to stabilize and reduce pelvic dislocations in emergency situations, and to assess possible difficult and easy aspects of the method. method: ganz clamp was used in the emergency treatment of 31 patients with severe lesions of the pelvic ring (tile c) associated to major hemodynamic instability. results: among the patients, 27 (87.1%) presented a favorable evolution, with stabilization, reduction of dislocations, and compression of the posterior portion of the ring, and also hemodynamic stabilization, and 4 (12.9%) died. conclusion: the ganz clamp was found to be an effective tool in the emergency treatment of pelvic ring lesions because it has an uncomplicated conception, allowing for a fast placement, because it does not prevent nor make it difficult for abdominal procedures, and most of all because it allows for the stabilization of the pelvis, reduction of dislocations, and compression in the posterior region of the ring, where most bleeding occurs, to reduce or eliminate bleeding.
Evolution of the Number of Students in Elementary and Secondary School in Portugal and Population Ageing  [PDF]
Cecília Rosa, Edgar Pereira
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.57008
Abstract: In this work, we present an application of a mathematical model structured in classes (see [1]) for the study of the influence of population ageing in the evolution of the number of students in elementary school and in secondary school in Portugal, from 1995/96 to 2014/15 (see [2]). Based on historical data, some scenarios of projection are presented, with the aim of quantifying the young student population and its relation with the structure of the population age for the next school years in Portugal (from 2016/2017 to 2020/2021), in the various study cycles. Furthermore, we make a comparative analysis between the projection results presented here and in references [3] and [4]. The dynamic of the model comprises two stages: the first one represents the flow of students that go from one school year to the next, as well as the flow of students that enter or leave the educational system in a certain cycle of studies. The second stage represents the flow of students that go to the next cycle of studies. The simulations were done using Matlab.

Abstract: For m experiments, COCs were collected from slaughterhouse ovaries and in vitro matured in TCM with 100 ng/ml of either BMP4 or Noggin. After 24 h, the nuclear stage of the oocytes was determined by staining with Hoechst 33342. In addition, RT-qPCR was performed on MII oocytes to study the relative concentration of ZAR1, GDF9, BAX, MATER and HSP70 transcripts. Treated oocytes were submitted to parthenogenic activation (PA) or in vitro fertilization (IVF) and cultured in CR2. For c experiments, non-treated matured oocytes were submitted to PA or IVF to generate embryos that were exposed to 100 ng/ml of BMP4 or Noggin in CR2 until day nine of culture. Cleavage, blastocyst and hatching rates, expression pattern of the transcription factor Oct-4 in blastocysts and embryo cell number at day two and nine post-activation or fertilization were evaluated.We found that Noggin, as BMP4, did not affect oocyte nuclear maturation. Noggin supplementation up-regulated the expression of HSP70 and MATER genes in matured oocytes. Moreover, BMP4 during maturation increased the proportion of Oct-4 positive cells in parthenogenic embryos. On the other hand, when Noggin was added to embryo culture medium, developmental rates of parthenogenic and in vitro fertilized embryos were reduced. However, BMP4 addition decreases the development only for in vitro fertilized embryos. BMP4 and Noggin during culture reduced the proportion of Oct-4-expressing cells.Our results show that BMP4 is implicated in bovine oocytes maturation and embryo development. Moreover, our findings demonstrate, for the first time, that a correct balance of BMP signaling is needed for proper pre-implantation development of bovine embryos.Bone Morphogenetic Protein 4 is a member of the transforming growth factor beta (TGFβ) superfamily which controls numerous events of embryonic, fetal and even adult development in all vertebrates [1]. Intracellular mediators of BMPs are Smad proteins which form a complex that is then trans

Abstract: La prevención de los comportamientos acerca del suicidio entre los adolescentes constituye actualmente una de las prioridades de intervención, contemplada en el Plan Nacional de Salud Mental. En el ámbito de este plan se defiende también la necesidad de desarrollo de respuestas y programas ligados a los Cuidados de Salud Primarios. En este sentido, ha sido delineado e implementado el Programa de Intervención intitulado BELIEVE, con objetivo de evaluar la autoestima y capacidad de resolución de problemas de los adolescentes e intervenir para mejorarla, integrado en el ámbito de la prevención de los comportamientos relacionados al suicidio en adolescentes. Este programa ha contemplado dos vertientes de actuación: una orientada para Técnicos de Cuidados de Salud Primarios y la otra para el medio escolar, con 106 adolescentes del 8o y 9o a os de escolaridad. Los adolescentes del sexo masculino tienen mayores niveles de autoestima y menos dificultades en la estrategia de resolución de problemas. La implementación del programa ha permitido mejorar el nivel de la autoestima y capacidad de resolución de problemas de los adolescentes.
