Published: July 2012

OBJETIVOS: Avaliar a função diastólica (FD) de crianças e adolescentes diabéticos tipo 1 (DM1). SUJEITOS E MÉTODOS: Estudo transversal de 67 DM1, sem comorbidades, e grupo controle (n = 84) da mesma faixa etária. Analisaram-se: idade, sexo, índice de massa corpórea (IMC), Dopplere-cocardiografia e eletrocardiograma de ambos os grupos e, nos portadores de DM1, o tempo de doença, HbA1C, lipidograma e o valor da microalbuminúria. RESULTADOS: Encontraram-se alterações diastólicas [(A e E mitral, relação E/A, tempo de relaxamento isovolumétrico (TRIV) e tempo de desaceleração da onda E (TDE)] nos diabéticos, com maior prevalência nas meninas na faixa 13-17 anos. TRIV e TDE correlacionaram-se positivamente com o IMC (p = 0,028). Idade e tempo de doença foram fatores preditivos para a onda A mitral (p = 0,004 e 0,033, respectivamente). CONCLUSÕES: Alterações de FD foram detectadas nos DM1, com maior prevalência em meninas púberes. Tempo de doença e idade dos pacientes influenciaram parâmetros de FD.

Published: July 2012

OBJECTIVE: To study the prevalence of shoulder pain and dysfunction in patients from Southern Brazil with diabetes mellitus (DM) and to evaluate the association of pain and dysfunction with diabetes control and epidemiological factors. SUBJECTS AND METHODS: We studied 150 patients with type 2 DM for pain and shoulder dysfunction with the UCLA-m (modified University of California at Los Angeles Shoulder Rating Scale); for epidemiological and treatment data, values of Hb A1C and plasma glucose were analyzed. RESULTS: Pain was present in 63.4%, and dysfunction in 53.4% of the studied sample; 26.6% of the patients rated shoulder performance as bad. No association was found between Hb A1C or plasma glucose and joint function, except for active flexion of the shoulder and fasting glucose (p = 0.026). Women had worse shoulder performance (p = 0.0043), as did elderly patients (p < 0.0001). CONCLUSIONS: Shoulder pain and dysfunction is highly prevalent in patients with type 2 diabetes; these disorders affect more women and the elderly.

Published: July 2012

A cultura do girassol tem recebido grande atenção em razão de suas características agronômicas e a possibilidade de inclusão nos sistemas de rotação de cultura. No entanto, as diferentes condições meteorológicas do período de cultivo determinam a ocorrência ou não de doenças, de modo que este conhecimento é fundamental para a escolha do melhor período de cultivo. Este trabalho teve por objetivo determinar a severidade de ocorrência das manchas de Alternária e septoriose em girassol (Helianthus annuus) semeado em diferentes épocas. Utilizou-se o delineamento inteiramente casualizado, bifatorial ("épocas de semeadura" x "híbridos de girassol") em quatro anos agrícolas de 2007 a 2011, em Santa Maria (RS). As medições fenométricas e as determinações de severidade das manchas de Alternária e septoriose foram feitas uma e duas vezes por semana, respectivamente. Obteve-se a severidade final observada (SVFO), e foram calculadas as variáveis área abaixo da curva de progresso da doença (AACPD) e dias com área foliar sadia (DAFS). Nos anos agrícolas de 2007/2008, 2008/2009 e 2010/2011, a severidade das doenças foi menor para as primeiras épocas de semeadura, de agosto a setembro, enquanto nas épocas tardias a tendência foi de aumento da severidade. Para 2009/2010, ano sob influência de El Niño, com chuvas acima da média, todas as épocas de semeadura tiveram alta severidade, com destaque negativo para as primeiras épocas, pois são nessas que se concentram os maiores volumes de chuvas em anos sob influência desse fenômeno. Portanto, semeaduras tardias ou em anos de El Niño são propícias à alta severidade de manchas de Alternária e septoriose em girassol, devendo ser evitada a semeadura nessas condições.
Movimentos sociais e democracia: a tensão necessária
Authors: Pereira Marcus Abilio
Published: July 2012

O presente artigo analisa algumas das críticas feitas às teorias deliberativas da democracia, de forma a resgatar o conflito como componente determinante para o desenvolvimento das democracias contemporâneas. Esta paisagem teórica permitiu um avanço em relação às questões da inclusão política, ao reconhecer a importância da autonomia política e ampliação da igualdade formal. Apesar destes avanços, as teorias deliberativas da democracia passaram a ser objeto de críticas em relação à excessiva ênfase no consenso, o que acabou por eclipsar outras formas de ação política, tais como as ações coletivas de conflito. Neste artigo, busco reforçar a importância da ênfase no conflito como elemento determinante para o desenvolvimento de nossas democracias. Para tanto, promovo um diálogo entre a teoria deliberativa da democracia e a teoria dos processos políticos, que tem como foco central a análise da relação entre os atores coletivos, suas políticas de conflito e o contexto político.
Atitudes, cognição e participação política: padrões de influência dos ambientes de socialização sobre o perfil político dos jovens
Authors: Fuks Mario
Published: July 2012

O debate sobre o papel da socialização na aquisição de conhecimento, na formação das atitudes e no padrão de participação política do jovem nos lembra, constantemente, que a família e a escola são os ambientes definidores nesse processo. Mas isso não esclarece uma série de questões. Uma delas é a interação entre os diversos fatores que compõem esses contextos socializadores e os mecanismos por meio dos quais eles geram efeitos sobre o perfil político dos jovens. Essa dinâmica é o foco do presente artigo e o nosso principal argumento é que ela cria padrões distintos na influência desses ambientes sobre o perfil político do jovem, dependendo da dimensão considerada. Nossas análises são feitas a partir dos dados de um survey realizado em 2008 com jovens do ensino médio da cidade de Belo Horizonte.
Voltando para casa: (re)encontrando Guerreiro Ramos, Tragtenberg e Prestes Motta
Authors: Oliveira Sidinei Rocha de , Ferreira Carolina da Silva
Published: July 2012

Este ensaio tem como proposta resgatar alguns aspectos do pensamento de Guerreiro Ramos, de Tragtenberge de Prestes Motta, destacando como a postura crítica e os questionamentos levantados por esses autorespermanecem atuais quando se analisa o papel do pesquisador, a influência da organização burocrática na sociedade atual, a aparente ingenuidade da administração escondida nas harmonias administrativas e no falso participacionismo e a relevância de considerarmos aspectos marcantes da cultura nacional. O ponto de partida deste texto é a vivência dos autores, que, apesar de diferentes históricos de vida, têm angústias bastante similares ao se moverem no circuito acadêmico e organizacional. Trata-se de um mundo onde existem questionamentos permitidos e temas "relevantes"; onde quem não herda ou não assume a postura de aprendiz - submetendo-se às regras existentes no "caminho para chegar lá" - é continuamente questionado.
Sustentabilidade do fazer artístico-cultural na cidade de Pelotas
Authors: Stael Maria , Pinto Rodrigo Serpa
Published: July 2012

Nos quase dois séculos de existência da cidade de Pelotas, sua tradição cultural tem sido reconhecida em todos os recantos do Rio Grande do Sul e, mesmo, em âmbito nacional. Mas, há muito, trabalhar com arte tem sido um processo cheio de reveses, pois envolve a produção de bens intangíveis e o fato de que consumir tais bens não implica sua posse. Quando isso ocorre, esses produtos nem sempre seguem a lógica capitalista do mercado de consumo - o qual busca vender mais quantidade do que qualidade - e a tendência é a de que não se consiga sustentar sua produção e distribuição.
A constituição do Pólo Moveleiro de Lucas do Rio Verde (MT): uma retrospectiva histórica de uma iniciativa coletiva de desenvolvimento local e regional
Authors: Sausen Jorge Oneide , Dalfovo Wylmor Constantino
Published: July 2012

Este artigo descreve e analisa o processo de formação e desenvolvimento do Pólo Moveleiro de Lucas do Rio Verde (MT), a partir de um estudo histórico-biográfico de um conjunto de pequenas e médias empresas que buscaram na parceria e na ação associativa a sua estratégia de sobrevivência e crescimento, numa região até então sem tradição industrial. Procurou-se constituir a linha histórica dessas organizações, descrevendo os seus processos de mudança organizacional e as suas estratégias de adaptação ao ambiente competitivo. Mostra, em conclusão, a contribuição do pólo moveleiro para o processo de desenvolvimento local e regional e as experiências das empresas constitutivas do pólo que oscilaram entre momentos de crise e de impacto negativo nos seus resultados econômicos e momentos de avanço na relação com o mercado, especialmente, no que se refere a um melhor posicionamento estratégico dessas organizações.
Redes e teias na gestão compartilhada dos consórcios operacionais de empresas de ônibus de Porto Alegre
Authors: Bichara Luiz Augusto , Fadul Élvia
Published: July 2012

Este artigo tem como objetivo analisar os consorcios de operação formados por empresas prestadoras de serviço público de transporte de passageiros por ônibus no municipio de Porto Alegre, na década de 1990. O estudo se propõe a investigar se os benefícios assegurados pelo modelo de organizações em rede podem ser estendidos a esses consorcios gaúchos. Buscou-se, também, caracterizar a estrutura de organização e entender o seu processo de formação. A pesquisa se desenvolveu com base em fontes secundárias e a partir de entrevistas com informantes-chave do sistema de transporte local, empresários consorciados, gestores públicos e representantes dos trabalhadores do setor. O estudo mostra que a experiência dos consórcios gaúchos apresenta resultados interessantes, sobretudo, nos seus aspectos institucionais e de negociação. Entretanto, o modelo se traduz, apenas, numa representação imatura ou incompleta do modelo de organizações em rede, não estando pronto para usufruir todas as suas vantagens, inclusive, no que tange à sua continuidade.
Participação social na Conferência Municipal de Olinda: mito ou realidade?
Authors: Pacheco Flávia Lopes , Silva Ana Beatriz Nunes da , Nogueira Alessandra Cabral
Published: July 2012

As manifestações realizadas no Brasil, a partir do final da década de 80, começaram a influenciar o novo discurso político que passou a simbolizar o interesse em promover um encontro mais amplo entre o Estado e a sociedade. O governo Lula trouxe novas esperanças para a sociedade, em que a Administração Pública passa a ser desenvolvida a partir de um modelo de gestão societal, e não mais gerencial. Assim, neste trabalho buscamos analisar se as práticas desenvolvidas pelo Ministério da Cultura Brasileiro, através da I Conferência Municipal Cultural de Olinda, realizada em 2005, podem caracterizar uma maior participação social na gestão da política de cultura nacional. O nosso intuito aqui foi o de compreender se essa prática está sendo desenvolvida a partir da participação tanto dos entes federados como da sociedade na elaboração de uma política pública nacional. No entanto, o que pudemos concluir é que o atual governo, apesar de possuir um discurso diferente dos demais, de parecer não destacar o neoliberalismo econômico e buscar efetivar a ação da sociedade, ainda está longe de promover uma plena participação social. Há que se analisar o processo democrático brasileiro de modo cauteloso, pois não é fácil dividir poderes, como foi percebido nesse caso.
Tecnologia Social de Mobilização para Arranjos Produtivos Locais: uma proposta de aplicabilidade
Authors: Ipiranga Ana Sílvia Rocha , Amorim Mônica Alves , Faria Maria Vilma Coelho Moreira
Published: July 2012

Apesar do crescente interesse que a abordagem de Arranps e Sistemas Produtivos Locais vem despertando no meio acadêmico e instituições públicas e privadas brasileiras, pouco se tem inovado acerca das formas de mobilização coletiva destas aglomerações produtivas territoriais, permanecendo as discussões nas áreas tradicionais de desenvolvimento das micro, pequenas e médias empresas. Este ensaio apresenta uma proposta de aplicação de uma Tecnologia Social de Mobilização dos atores/agentes de um arranjo produtivo local, objetivando o seu desenvolvimento, através do fortalecimento das relações existentes entre seus diversos atores/agentes localizados no território. Espera-se, através da exposição de uma possível aplicabilidade desta Tecnologia Social, gerar um debate sobre formas criativas de mobilização desses arranps organizacionais, que privilegiem aspectos intangíveis, não obstante serem de fundamental importância, tais como: capital social, práticas cooperativas e governança.
A inserção da lógica de mercado no campo cultural: a relação entre as instituições bancárias e a cultura em Recife
Authors: Lorêto Myrna Sueli da Silva , Pacheco Flávia Lopes
Published: July 2012

Ao se falar de cultura pernambucana, percebe-se que alguns grupos responsáveis por manifestações tradicionais estão encontrando dificuldades em permanecer realizando essas atividades culturais. Este fato decorre, entre outros motivos, devido à reforma do Estado que tende, a cada dia que passa, a diminuir os investimentos diretos em cultura, fazendo-o por meio de leis de incentivo à cultura e renúncia fiscal. É nesse contexto que as instituições bancárias perceberam uma nova fatia do mercado a atingir: o setor cultural. A fim de obterem legitimidade perante a comunidade da qual fazem parte, os bancos começam a se utilizar dos mecanismos governamentais, como as leis de incentivo à cultura, para conseguirem isenção de impostos ao financiarem projetos culturais e, ao mesmo tempo, alcançarem visibilidade junto à mídia enquanto organizações socialmente responsáveis. Assim, propomo-nos a discutir de que modo está configurado o campo cultural que se formou a partir das ações de financiamento das instituições bancárias em Recife. Para isso, tomamos como base a Teoria Institucional, pois ela destaca aspectos como: o ambiente onde essas organizações estão inseridas e a noção de campo.
A postura do professor e as grandes questões humanas nas práticas educacionais
Authors: Fraga Valderez F.
Published: July 2012

A postura do professor é um desafio, não importa onde ou quando. Problemas a ela inerentes se tornam agudos nos países em desenvolvimento, onde os contrastes vão do urbano às áreas rurais, da pobreza à sociedade tecnologicamente avançada, demandando, simultaneamente, compreensão humana e rápida atualização do conhecimento. A descrição da experiência de duas turmas de educação continuada visando à postura docente discute a disposição dos professoresalunos de enfrentarem grandes questões humanas como a democracia, sem descuidar de conteúdos específicos. O objetivo central deste estudo é alertar os educadores sobre a significância de lidar com a postura e o conhecimento. Nesse sentido, vários recursos e abordagens de ensino -além de concorrentes métodos de pesquisa qualitativa -foram previamente escolhidos para que se atingisse, respectivamente, os objetivos de ensino e melhores resultados na pesquisa. Os resultados emergiram em preocupações dos professores-alunos, motivados a assumir uma postura democrática e concretamente dialógica, no sentido da inclusão socioeducacional. As conclusões revelam tanto manifestações singulares de cada turma, sugerindo futuras pesquisas quanto posições intercomplementares e percepções comuns a ambas.

Published: July 2012

The main goal of this study was to assess the nature and magnitude of gene effects for resistance to Cercospora leaf spot. A randomized block design with three replications was used. The data were obtained at the plant level by assessing the disease severity. The data were analyzed per experiment, using the average data per plot. A dominant-additive genetic model without epistasis was considered, with estimation of the components of means and variance. The genetic control of resistance to gray leaf spot is polygenic with predominance of the additive effects. Dominance was observed in a few small-effect loci and high heritability values.

Neste trabalho, investigou-se a percepção dos profissionais de enfermagem sobre a influência do suporte social na incidência da Síndrome de Burnout. Para tanto, utilizou-se uma survey junto a 231 colaboradores de quatro hospitais públicos e privados do Rio Grande do Sul. Os resultados revelam que tais profissionais apresentam grau moderado da Síndrome, sendo que os entrevistados dos hospitais públicos evidenciaram maiores índices da doença e, consequentemente, menor suporte social no trabalho, quando comparados aos indivíduos dos hospitais privados. Além disso, através dos modelos de regressão múltipla, nas instituições públicas, o modelo Esgotamento Emocional foi previsto pelos fatores suporte social informacional e confiança, em 31% da variância explicada. Já nas instituições privadas, a dimensão realização pessoal foi explicada em 23% pelos fatores suporte social informacional, confiança e clareza e agilidade das informações, evidenciando a influência do suporte social no trabalho na incidência da Síndrome de Burnout.
Ontogeny of the redlichiid trilobiteMetaredlichia cylindricafrom the lower Cambrian (Stage 3) of South China
Authors: Dai Tao , Zhang Xingliang
Published: July 2012

A number of immature and mature exoskeletons allow the first detailed description of the ontogeny of the early Cambrian redlichiid trilobiteMetaredlichia cylindrica, from black shale of the Shuijingtuo Formation in Hubei Province, South China. The material includes numerous complete protaspides, within which two stages can be differentiated according to the appearance of a shallow furrow that separates the protopygidial area from the protocranidium. Also, identification of the subsequent ontogenetic stages, including meraspides and holaspides, depends on isolated cranidia that display prominent morphological changes such as the contraction of frontal glabellar lobe, appearance of the fourth pair of glabellar furrows, and modification of the facial suture from proparian to opisthoparian. Incorporating the whole ontogenetic sequence allows us not only to trace the developmental trends of various structures with growth, but also to assign the protaspides to their adults correctly, particularly with the help of meraspid specimens.

Middle and late Permian foraminifers from the Chichibu Belt, Takachiho Area, Kyushu, Japan: implications for faunal events
Authors: Kobayashi Fumio
Published: July 2012

The middle and late Permian to Triassic sequence of carbonate rocks in the Takachiho area, central Kyushu, Japan, originated as a Panthalassan seamount and formed parts of far-traveled accreted terranes. This succession is divided into the Permian Guadalupian Iwato and Lopingian Mitai formations, and the Triassic Kamura Formation. The Iwato Formation is further into three zones, the Neoschwagerina, Yabeina higoensis, and Neoendothyra permica zones in ascending order; the Mitai Formation includes the Nanlingella suzukii Zone. Biotic turnovers are recorded twice in the Iwato and Mitai formations. The first and more remarkable biotic event is the total disappearance of fusulines at the top of the Yabeina higoensis Zone. The Neoendothyra permica Zone is characterized by black fine-grained micritic limestones having only sparse non-fusuline foraminifers. The second biotic event is the first appearance of Wuchiapingian fusulines by which the Nanlingella suzukii Zone is defined. The Capitanian–Wuchiapingian boundary is drawn between the Neoendothyra permica and Nanlingella suzukii zones. Above this boundary both the numbers of individual foraminifers and diversity of species gradually increase. The turnovers recorded in the Takachiho area were the result of late Capitanian–Wuchiapingian environmental changes which were sufficient to cause the disappearance of large, multi-chambered fusulines and allow the new appearance of an ‘ultimate’ Paleozoic foraminiferal assemblage. Ten species of foraminifers, including Yabeina higoensis and Yabeina Columbiana, are described.
Calosargus talbragarensisnew species: the first brachyceran fly from the Jurassic of Australia (Diptera, Archisargidae)
Authors: Oberprieler Stefanie K. , Yeates David K.
Published: July 2012

The first fly fossil discovered from the Upper Jurassic Talbragar Fish Bed in Australia is described and illustrated. Based on a single, well preserved wing,Calosargus (Calosargus) talbragarensisnew species is assigned to the extinct brachyceran family Archisargidae. Wing morphology suggests a relationship between this extinct family and Stratiomyidae. The Archisargidae have so far only been found in China, Kazakhstan and Mongolia.CalosargusMostovski, 1997 currently comprises seven species from the Callovian (late Middle Jurassic) of China and three species from the Oxfordian (early Upper Jurassic) of Kazakhstan. This oldest brachyceran fossil from Australia and first record of the Archisargidae in the southern hemisphere presents evidence that higher flies were present in this region in the Jurassic, when this group is thought to have commenced its diversification.
New bothremydid turtle (Testudines, Pleurodira) from the Paleocene of northeastern Colombia
Authors: Cadena Edwin A. , Bloch Jonathan I. , Jaramillo Carlos A.
Published: July 2012

A new turtle, Puentemys mushaisaensis, from the middle to late Paleocene Cerrejón Formation of Colombia, is described on the basis of a partial skull and many partial to nearly complete carapaces and plastrons representing multiple ontogenetic stages. Whereas P. mushaisaensis is unique in aspects of its shell morphology, it shares many diagnostic characteristics of bothremydid pleurodirans, including a long exoccipital-quadrate contact, a very low and rounded almost circular carapace, and a thinner internal bone cortex than that of the external cortex in both the carapace and plastron. With a maximum carapacial length of 151 cm, P. mushaisaensis is the largest known bothremydid turtle and represents the first occurrence of bothremydids in the Paleogene of South American tropics. Results from a cladistic analysis of bothremydids indicate that P. mushaisaensis shares a close relationship with Foxemys mechinorum from the Late Cretaceous of Europe, indicating a wide-spread geographical distribution for bothremydines during the Late Cretaceous–Paleocene.
Reassessment of the Early Cretaceous non-marine ostracod generaHourcqiaKrömmelbein, 1965 andPattersoncyprisBate, 1972 with the description of a new genus,Kroemmelbeincypris
Authors: Poropat Stephen F. , Colin Jean-Paul
Published: July 2012

The Early Cretaceous non-marine ostracod generaHourcqiaKrömmelbein andPattersoncyprisBate are reinstated. A previously published referral ofHourcqiatoCyprideaBosquet is rejected due to the absence of an anteroventral rostrum in the holotype of the type speciesHourcqia africanaKrömmelbein. The genusHourcqiais characterized by an “inverse” valve ratio (right valve larger than left) and the lack of an anteroventral rostrum, and the diagnosis of the genus is broadened to accommodate ornamented forms, resulting in the acceptance of five species:Hourcqia africana,H. confluens(Krömmelbein and Weber),H. kouilouensis(Grosdidier),H. bateke(Grosdidier) andH. sylvesterbradleyi(Bate). The previously published synonymy ofPattersoncypriswith the genusHarbiniaTsao is also rejected. The diagnosis ofPattersoncyprisis refined, meaning that three species are recognized:Pattersoncypris micropapillosaBate,P. salitrensis(Krömmelbein and Weber), andP. sinuata(Krömmelbein and Weber). The new genusKroemmelbeincyprisis erected for two species initially assigned toHourcqia, and subsequently toPattersoncyprisandHarbiniaby different authors:Kroemmelbeincypris symmetrica(Krömmelbein and Weber) andK. angulata(Krömmelbein and Weber). The genusHourcqiais diagnostic of latest Barremian non-marine settings, whilstPattersoncyprisandKroemmelbeincyprischaracterize Aptian saline lacustrine environments. The geographic ranges of all three genera are restricted to northeastern and eastern Brazil and northern and western Africa, though a species ofPattersoncypris(P. dakotaensisTibert and Colin) is also present in the United States.
A Review of Standardized Developmental Assessment Instruments for Young Children and Their Applicability for Children With Special Needs
Authors: Visser Linda , Ruiter Selma A. J. , Meulen Bieuwe F. van der , Ruijssenaars Wied A. J. J. M. , Timmerman Marieke E.
Published: July 2012

This article provides a review of contemporary instruments for the developmental assessment of children aged 0–4 years and their applicability for children with special needs. The issues involved in the developmental assessment of children with special needs are discussed, and, on the basis of these issues, various instruments are then evaluated.

Method:A literature search was carried out for articles about or using standardized developmental assessment instruments for children aged 0–4 years.

Results:Eighteen instruments were found, of which 2 were nonverbal and 2 were designed for motor-impaired children. The instruments varied in terms of their suitability for children with special needs.

Conclusion:The range of instruments is limited, especially for children younger than 2 years of age. Instruments for children with motor or hearing/language impairments are available, but their psychometric properties need to be researched and improved. For children with a visual impairment, no appropriate instrument is currently available.
The Increase in Colored Progressive Matrices Test Performance in Individuals With Down Syndrome: A Qualitative and Quantitative Review
Authors: Lanfranchi Silvia , Carretti Barbara
Published: July 2012

It is well known that a normal population improves its IQ test scores by about 3 points per decade. This is called the Flynn effect and has been explained in different and sometimes contrasting ways. Few and ambiguous data are available on any Flynn effect in individuals with an atypical development, such as those with intellectual disabilities: some studies report evidence of the Flynn effect, whereas others do not. The main objective of the present study was to analyze the performance of individuals with Down syndrome (DS) compared with a sample of typically developing (TD) children in the Colored Progressive Matrices (CPM) test, which measures abstract reasoning and is commonly used to estimate IQ, to see whether a Flynn effect is present. Our results suggest that the Flynn effect in the DS population depends on the individual’s age.
Competition between particles and dissolved organic matter for trace metal binding in unpolluted soil solutions: Monitoring and thermodynamic approaches
Authors: Pelfrene Aurélie , Gassama Nathalie
Published: July 2012

In this study, monitoring and thermodynamic approaches were combined in order to identify the dominant features, which control the speciation of Cd, Cu, Pb, and Zn in solutions from unpolluted planosolic soil (North Massif Central, France). Three sites were selected according to topography and monitored from January to May 2006 using piezometers. The sandy-loam to clay-loam organic-rich horizon (horizon A) and the gravely and concretion-rich horizon (horizon E) were chosen to assess the potential impact of type of horizon on the chemical speciation of metals in the soil solutions. Binding of metals to organic ligands was studied by differential pulse anodic stripping voltammetry (DPASV) in order to acquire experimental data which could be used for the validation of speciation models. These data, together with data from the literature on properties of natural particulate matter, were used to determine the speciation of Cd, Cu, Pb and Zn with a thermodynamic code (PHREEQC). The observed and predicted speciation were compared to estimate the contributions of natural dissolved organic matter and of particles to the binding of metal ions. There was a good match between observed and predicted results, validating the approach used. Results show that particles (mixed iron and aluminium oxides ± clays ± organic matter) play the main role in the speciation of the trace metals in soil waters rather than complexation with dissolved organic matter. Moreover, particles govern speciation to a greater extent in horizon E than in horizon A, which can be linked to hydrodynamics (reaction time between water and soil due to porosity) and chemical reactivity of the solution circulating.
Tectono-sedimentary model for the evolution of the Silves Group (Triassic, Lusitanian basin, Portugal)
Authors: Soares António Ferreira , Kullberg José Carlos , Marques Júlio Fonseca , da Rocha Rogério Bordalo , Callapez Pedro Miguel
Published: July 2012

At the beginning of the Alpine cycle, the breakup of Pangea lead to the early stages of the North Atlantic opening. In the western Iberian sector of the European margin, the Lusitanian basin starts to evolve bordered eastwards by inherited reliefs from the late episodes of the Variscan orogeny. The base unit, the Silves Group, considered not earlier than the Carnian, is mainly siliciclastic and predominantly formed by arcosarenites to feldspar litarenites, coarse to very coarse-grained (wackes) and pebbly, where the sediment architecture denotes organizations in continental (Conraria, Penela and Castelo Viegas Formations) environments. A first marine episode (Isocyprina Beds of Pereiros Fm.) marks a significant change within the sedimentary record; the uppermost part corresponds to intertidal transitional environments (sabkha). New and detailed field work of sedimentological and structural nature that has been carried out in recent exposures from the type-region of Coimbra-Penela enabled us to make significant observations and to improve data collection. This allowed a full reinterpretation of the paleotectonic and paleogeographical conditions under which the Silves Group and, consequently, the eastern border of the Lusitanian basin, evolved. This study carried out in the type-region also allowed a better understanding of its sequential organization. All units are unconformity bounded by strong influxes of coarse siliciclastics from the Iberian meseta. One of those unconformities (D2b) is an angular unconformity with cartographic expression. Tectonic reconstructions were possible to make after a detailed structural analysis of normal synsedimentary faults. Regional comparisons with Eastern Iberian basins that evolved since Permian times are also discussed. We conclude that the lower red siliciclastic units are older than has been considered until now. Those units were formed in a previous tensional stress pattern of tardi-Variscan affinities, related to megashear dextral kinematics of Permian-Triassic age. We propose that units below D2b unconformity can record a Proto-Lusitanian basin; the Lusitanian basin is younger and evolved mainly after the Triassic-Jurassic limit (Castelo Viegas Fm.) within an E-W extensional context related to Atlantic type basins.

Published: July 2012

At present, typical approaches employed to repair fractures and other bone lesions tend to use matrix grafts to promote tissue regeneration. These grafts act as templates, which promote cellular adhesion, growth and proliferation, osteoconduction, and even osteoinduction, which commonly results in de novo osteogenesis. The present work aimed to study the bone-repairing ability of hybrid matrixes (HM) prepared with polyvinyl alcohol (PVA) and bioactive glass in an experimental rabbit model. The HM were prepared by combining 30% bioactive glass (nominal composition of 58% SiO2 -33 % CaO - 9% P2O5) and 70% PVA. New Zealand rabbits were randomly divided into the control group (C group) and two groups with bone lesions, in which one received a matrix implant HM (Implant group), while the other did not (no Implant group). Clinical monitoring showed no altered parameters from either the Implant or the no Implant groups as compared to the control group, for the variables of diet grades, day and night temperatures and hemograms. In the Implant group, radiologic and tomographic studies showed implanted areas with clean edges in femoral non-articular direction, and radio-dense images that suggest incipient integration. Minimum signs of phlogosis could be observed, whereas no signs of rejection at this imaging level could be identified. Histological analysis showed evidence of osteo-integration, with the formation of a trabecular bone within the implant. Together, these results show that implants of hybrid matrixes of bioactive glass are capable of promoting bone regeneration.

plastics are dumped into landfills. An experiment was conducted in a laboratory scale batch process under Labconco’s
fume hood utilizing low density polyethylene (LDPE). The experiment was carried out to obtain a hydrocarbon fuel
product utilizing thermal degradation. Many research studies have successfully demonstrated that waste plastics such as
low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene (PP) and polystyrene (PS) can be
converted to valuable liquid hydrocarbon fuels. For experimental purposes we used 500 gm of LDPE as raw materials.
This particular experiment is a two step process; the first step process involves extracting hydrocarbon fuels as mixture of
both short and long chain hydrocarbon compounds. During the second step the fuel obtained in the first process is
refractionated by thermal degradation process utilizing a distillation column. This process yields a short hydrocarbon
chain liquid fuel that has similar properties to gasoline grade fuels. Analysis of these fuels was conducted by Gas
Chromatography and Mass Spectrometer (GC/MS), FT-IR Spectrum 100 and Differential Scanning Calorimeter (DSC).
The results show that the produced fuels are good quality fuels with high energy content. ASTM test result indicates that
fuel has low sulfur level (3.2 ppm) and the fuel hydrocarbon range shown by GC/MS analysis is C4-C10.

Published: July 2012

The study of the interaction of chromium with O-donor humic-like ligands is
performed by electrospray-ionization mass spectrometry (ESI-MS) and
ultraviolet/visible (UV/VIS) spectrophotometry. Heterogeneity of functional
groups justifies the use of model compounds of humic substances. For studying
the interaction of chromium with humic substances as model substances were
used benzoic, salicylic, phthalic and citric acid, which include O-donor
atoms, also present in heterogenous and polydispersed ligands, such humic and
fulvic acids are. The intensity of the interaction is correlated with the
acid-base and electron-donor properties, geometric and steric
characteristics, and the number and the positions of O-donor atoms in the
investigated ligands. UV/Vis data describing chromium interaction with
humic-like ligands is placed in correlation with the ESI-MS data of the
complexes, both in quantitative and in qualitative terms. UV/VIS spectroscopy
and ESI-MS quantification showed a large difference in the informativeness of
describing the interaction of chromium(III)-ligand, in favor of ESI-MS
technique. ESI-MS technique can be used for quantitative analysis of the
system Cr(III)-ligand. ESI-MS ion current chromatograms of 20 ?L loop
injections of systems Cr(III)-ligand, indicate a stabile peak and signal
integrity.
The precision of time registration with Danjon astrolabe
Authors: Perovic G. , Cvetkovic Z.
Published: July 2012

During 1988 at the Munich, Vienna and Graz stations selected stars were
observed for the purpose of determining difference in the longitudes. The
measurements were performed with Danjon astrolabe by using the method of
equal zenith distances. In the present paper the authors analyze the
registration precision of 1604 star transits over a given almucantar. They
estimate the variance of registration of star transits over a fictive thread
as function of declination and parallactic angle before and after elimination
of gross errors.
Generalized Schuster law and King’s formula
Authors: Zivkov V. , Ninkovic S.
Published: July 2012

By varying a particular form of the generalized Schuster density law (the
exponent in the denominator equal to 3/2) the authors look for a suitable
substitution for King?s density formula usually applied to star clusters and
dwarf galaxies. The authors find expressions yielding almost identical
density values as King?s formula, but from the mathematical point of view
significantly more simple for use.
Pressure at the ISM-halo interface: A reheating frequency dependence
Authors: Cirkovic M.M.
Published: July 2012

The dependence of the thermal pressure of hot galactic halos on a model
parameter describing the frequency of major reheating episodes during
galactic history is investigated. Pressure on the interface between
interstellar medium and the halo gas is especially interesting, since
empirical evidence here offers one of the simplest constraints on halo
models. It is shown that two-phase model of Mo & Miralda-Escud? is
sufficiently robust with respect to uncertainties in the average interval
between reheating.

Methods of smoothing applied to differences in star positions in observational catalogues
Authors: Popovic N.
Published: July 2012

Three different methods, Whittaker - Robinson - Vondrak (WRV), cubic spline
(SPL) and Expansion of the Elementary Trigonometric and Exponential Functions
(ETE), are applied to differences in star positions of five observational
catalogues in order to eliminate random errors. The Belgrade, Kiev, Moscow,
Odessa and Kharkov catalogues of double stars (DS) programme have been used.
The ETE method appears as reliable and even somewhat more efficacious that
the usual WRV and SPL methods.
The zonal satellite problem - II: Near-escape flow
Authors: Mioc V. , Stavinschi M.
Published: July 2012

The study of the zonal satellite problem is continued by tackling the
situation r??. New equations of motion (for which the infinite distance is a
singularity) and the corresponding first integrals of energy and angular
momentum are set up. The infinity singularity is blown up via McGehee-type
transformations, and the infinity manifold is pasted on the phase space. The
fictitious flow on this manifold is described. Then, resorting to the
rotational symmetry of the problem and to the angular momentum integral, the
near-escape local flow is depicted. The corresponding phase curves are
interpreted as physical motions.
Co-existence of two plasma phases in solar and AGN coronas
Authors: Kubicela A. , Arsenijevic J. , Popovic L.C. , Trajkovic N. , Bon E.
Published: July 2012

Here we have juxtaposed two distant cosmic locations of the Sun and AGN where
neutral hydrogen appears in a close connection with hot coronas. Besides the
solar photosphere, chromosphere and prominences where the presence of neutral
hydrogen is well established, its emission quite high in hot solar corona is
still puzzling. Some of earlier observations where H? emission in solar
corona was detected in eclipse and in daily coronagraphic observations are
reviewed. A proper theoretical explanation of this cold chromospheric-type
emission in the hot corona does not exist yet. On the other side, a similar
emission of hydrogen lines is present in Active Galactic Nuclei (AGNs). Much
research work is currently being done in this field. We outline some of the
concepts of the AGN structure prevailing in the astrophysics today.

Constrained deconvolution by explicit correction of fourier components of the unknown distribution
Authors: Jankov S.
Published: July 2012

The physical constraints were applied in the problem of deconvolution by
explicitly correcting noise affected Fourier components of the unknown
distribution. The method gives the constrained estimate optimal in the
quadratic sense, i.e. the estimate closest to the exact solution in the
Euclidean space of solutions. The properties of the method were theoretically
examined and some practical applications in the astronomical spectroscopy
have been effected. The method is compared with the similar Fourier spectrum
extrapolation procedures; as a consequence application of the method is
recommended particularly in the case of low signal-to-noise measurements.
The future of galaxies and the fate of intelligent life
Authors: Cirkovic M.M.
Published: July 2012

We investigate the influence of recent advances in research on the gaseous
content of the universe on our knowledge of star formation histories of
spiral galaxies. The discovery of low-redshift population of absorbers and
first steps made in understanding of the transition between high-redshift
intergalactic and low-redshift galactic population of QSO absorption systems
significantly reshape our picture of the gaseous content of the universe. It
turns out that large quantities of gas which has not been astrated or
astrated only weakly are bound to galaxies at later epochs, and present a
potential reservoir of gas not only for solution of the gas consumption
puzzle in spiral disks, but also a fuel for future star formation. This
baryonic transition, although still hard to establish quantitatively, is a
result of the simple physical processes. The resulting increase in the star
formation timescales of spiral galaxies has some interesting consequences for
the long-term future development of life and intelligent observers in the
galactic context. Admittedly highly speculative, this qualitative picture may
hopefully provide a motivation for detailed numerical modelling of the
physical processes involved.
