Authors: Santos Carlos Antonio Costa dos , Brito José Ivaldo Barbosa de
Published: January 2008

Este trabalho objetiva verificar as tendências de índices de detecção de mudanças climáticas, dependentes da precipitação pluvial diária, nos estados do RN e PB e analisar suas relações com o IVDN e anomalias de TSM nas regiões de Niño 1+2, Niño 3, Atlântico Tropical Norte (ATN) e Atlântico Tropical Sul (ATS). Utilizou-se dados de precipitação de 44 postos, no período de 1935 a 2000, representando todas as microrregiões dos dois Estados; de IVDN, obtidos da NOAA/AVHRR, no período de 1980 a 2000 e de anomalias de TSM, cedidos pela NOAA, de 1950 a 2000. Observou-se uma tendência de aumento das condições de umidade sobre os dois estados. O índice dias consecutivos secos apresentou correlação estatisticamente significativa com as anomalias de TSM das áreas ATN e ATS. Enquanto, os índices dias muito úmidos e quantidade máxima de chuva em cinco dias mostraram correlações significativas com as regiões dos Niño 1+2 e 3 e com a TNA. Em geral, observou-se que o IVDN da Caatinga é mais dependente dos extremos de precipitação do que os da Mata Atlântica. De acordo com os resultados obtidos concluiu-se que as mudanças climáticas detectadas pelos índices são resultantes tanto dos fatores de grande escala como de escala local. Outro resultado obtido foi influência do ENOS sobre os índices extremos de chuva e consequentemente sobre clima e a dinâmica da vegetação do Semi-árido.

Apesar dos avanços da modelagem dinâmica da atmosfera nas últimas duas décadas do século 20 as aplicações com modelagem empírica ainda têm sido muito utilizadas em função do seu fácil uso e pouca dependência de recursos computacionais. Neste estudo é mostrada uma comparação dos resultados de simulação de precipitação para o Nordeste do Brasil (NEB) - 1971-2000 obtido por modelagem dinâmica de grande escala e regional (downscaling) e a previsão de um método de modelagem empírica K´neigbhors. Foram usados o modelo de circulação geral da atmosfera ECHAM4.5, e dois modelos regionais, o Modelo Regional Espectral (MRE/97) do National Centers for Atmospheric Prediction- NCEP e o Regional Atmospheric Model System (RAMS) desenvolvido na Universidade do Colorado. Os modelos regionais foram aninhados aos dados simulados pelo ECHAM4.5 tendo como condição de contorno a Temperatura da Superfície do Mar observada no período de fevereiro a maio. Os resultados mostraram que o modelo empírico apresentou menor erro absoluto nos períodos fevereiro a abril (FMA) e março a maio (MAM) que os modelos dinâmicos em áreas do no norte do Maranhão e Piauí, oeste e sul do Ceará, centro-sul do Piauí e oeste e nordeste da Bahia. Quanto ao bias, o ECHAM4.5 e o MRE/97 mostraram um bias úmido em grande parte do NEB, porém com um valor médio para o setor norte do NEB (2ºS-12ºS e 45ºW-37ºW) mais próximo do observado. Para o RAMS e o método análogo houve um predomínio de um bias seco sobre o NEB, com valores em magnitudes mais distantes do observado. A previsibilidade (Heidke Skill) em três categorias Seca (S), Normal (N), Chuvosa (C), mostrou que o método análogo tem baixo Skill, entre 0,1 e 0,3 em todas as categorias, enquanto os modelos dinâmicos apresentaram Skill superiores, com valores maiores para as categorias S e C (da ordem de 0,4 a 0,5), até superiores a 0,6 em algumas áreas do setor norte do NEB para a categoria C como visto nos resultados dos modelos ECHAM4.5 e MRE/97.

Published: January 2008

O objetivo deste trabalho é determinar as matrizes de estado que representam uma linha de transmissão cujos parâmetros são considerados variáveis em relação à freqüência. Inicialmente a linha é representada por meio de uma cascata de circuitos pi, sendo que o efeito da freqüência sobre os parâmetros longitudinais da linha é sintetizado por meio de uma associação série e paralela de resistores e indutores que é inserida em cada um dos circuitos pi. Esta cascata é então descrita por meio de variáveis de estado. O modelo será utilizado para representar uma linha monofásica, levando em consideração que os parâmetros da mesma são dependentes da freqüência. As simulações serão realizadas no ambiente Matlab. Para conferir a regra de formação das matrizes de estado, os resultados obtidos com a representação proposta serão comparados com os resultados obtidos com o Microtran.

Muitos estudos demonstram que programas de atividade física são eficazes para estimular o metabolismo ósseo, sendo utilizados como uma modalidade terapêutica em caso de perda óssea devido a osteoporose. Entretanto, vários pontos relacionados a intensidade e freqüência ideal para do exercício físico ainda não estão esclarecidos. Com isso, o objetivo deste estudo foi determinar os efeitos de um programa de exercícios físicos de alta intensidade na morfometria, na força óssea e no conteúdo mineral do fêmur de ratas osteopênicas. Foram utilizadas 40 ratas, distribuídas em 4 grupos: grupo intacto sedentário (SS); grupo osteopênico sedentário (OS); grupo intacto treinamento (ST) e grupo osteopênico treinamento (OT). O programa de exercício foi iniciado 8 semanas após a ovariectomia e foi realizado 3 vezes por semana, durante 8 semanas. Cada sessão foi constituída por 4 séries de 10 saltos cada. Após a eutanásia dos animais, os fêmures foram retirados e processados para as analises. RESULTADOS: os animais osteopênicos sedentários demonstraram uma diminuição da força óssea e uma diminuição dos pesos ósseos, da densidade óssea e do conteúdo de cálcio. As ratas osteopênicas exercitadas mostraram maiores valores na avaliação dos pesos ósseos, da força óssea, da densidade óssea e do conteúdo mineral, evidenciando o efeito positivo deste protocolo no metabolismo ósseo. Os resultados deste estudo indicam que a intensidade e a duração do programa de exercícios utilizado foi eficaz para produzir modificações nas propriedades geométricas e na forca óssea, nos fêmures das ratas osteopênicas, o que contribuiu para reverter as perdas ósseas após a ovariectomia.
From Alma-Ata to the Global Fund: the history of international health policy
Authors: Maciocco Gavino , Stefanini Angelo
Published: January 2008

'Verticalization' of health care delivery, in one form or another, is the common theme pervading the history of international health policy over the last sixty years. It is often accompanied by radical policies of privatization of health services, everywhere resulting in people being forced to pay for all services. The failure of the vertical approach, of which the global public-private partnership initiatives are a modernized version, has been well recognized and its reasons are clear: actions on the distal determinants of disease (income, education, housing, the environment and infrastructure, etc) are overlooked; distribution of services dedicated to specific diseases and interventions (such as AIDS, malaria, tuberculosis, etc.) are artificially and temporarily reinforced, creating absurd and harmful forms of competition between services and making even more precarious and inefficient the work of already fragile basic health systems. This article describes the role played in this disturbing historical development by the prevailing economic ideology and its operational arm, the World Bank, with the view to reclaim international policy making processes and actors that really respond to people's health needs.
Anthropometric normality in adults: the geographical and socio-economic paradox of the nutritional transition in Brazil
Authors: Batista Filho Malaquias , Miglioli Teresa Cristina , Santos Marcela Carvalho dos
Published: January 2008

OBJECTIVES: to consolidate secondary data and provide some as yet unpublished information on changes in the nutritional status of Brazilian children, and, principally, adults, from an anthropometrical point of view as evaluated in the course of the most recent surveys, laying emphasis on geographical and socio-economic features. METHODS: tables and graphs were used to consolidate data published by the Brazilian Institute of Geography and Statistics and from other sources, along with estimates for results not included in these original documents. Preliminary data from two as yet unpublished studies were also included. RESULTS: it was shown that, alongside the decline in malnutrition in children there are signs of an epidemic increase in obesity and overweight in adults. This is characteristic of the change in epidemiological profile associated with the nutritional transition. There is an apparent paradox that the highest frequencies for normal anthropometric measurements in adults were found in the poorer North and Northeast regions of Brazil. These results were even found in localities with very low indices for human development in the Northeast region. The best anthropometric situation for adult populations in Brazil was found in families with a low income (less than ¼ of one minimum wage per household per capita, with a prevalence rate twice as high among adult males in comparison with the higher household income group). CONCLUSIONS: the results for nutritional anthropo-metry among adults, showing more normal measurements among the low-income population, reflect a peculiar phase in epidemiological terms in the process of the nutritional transition in the country, which constitutes a paradox arising in these specific circumstances, which is probably temporary.
Facial attractiveness: General patterns of facial preferences
Authors: Kościński Krzysztof
Published: January 2008

This review covers universal patterns in facial preferences. Facial attractiveness has fascinated thinkers since antiquity, but has been the subject of intense scientific study for only the last quarter of a century. Many facial features contribute to facial attractiveness: Averageness and symmetry are preferred by males and females, probably because they signal genetic quality and developmental stability. Men prefer highly feminized female faces because they reflect high estrogen levels and low testosterone levels. This indicates that the woman is reproductively healthy. Women, on the other hand, prefer a moderate level of male facial masculinity, since facial masculinity that is too pronounced signals high level of testosterone and, thereby, a poorly developed pro-family personality. In women, facial hair is detrimental to facial attractiveness. In men, the effect is not consistent. Faces with a clear complexion are attractive to both men and women. Men prefer light and smooth skin in women. Positive facial expressions also enhance facial attractiveness. Many factors, in particular skin condition and facial proportions, affect perceived age, which is an important component of facial attractiveness. Men in particular strongly prefer youthful-looking female faces. Facial preferences enable an individual to recognize reproductively fit mates. Therefore, facial preferences are adaptive, although non-adaptive mechanisms related to general brain function also play a role.
The alchemy of human variation: Race, ethnicity and Manoiloff’s blood reaction
Authors: Naidoo Nicollete P. , Štrkalj Goran , Daly Thomas J.M.
Published: January 2008

This paper examines the research on race determination conducted by Russian biochemist E.O. Manoiloff in the 1920s. Manoiloff claimed to have discovered a method which detected racial identity of an individual by a simple chemical reaction performed on a subject's blood sample. The method was published in one of the leading anthropological journals and it was not questioned for some time. It is obvious today that Manoiloff's claims were nothing short of ridiculous. The present study, based on the experimental history of sciences, tries to elucidate Manoiloff's procedures and reasons for his ‘success’. His experiments were repeated using both original and modern equipment. It has been demonstrated that Manoiloff's procedures, although rigorous at first glance, were highly arbitrary and methodologically flawed. It would appear that the socio-political and scientific contexts of the early twentieth century which favoured belief in the existence of clearly distinguishable racial types played a crucial role in the initial positive response to Manoiloff's research.
Assessment of the BMI, WHR and W/Ht in pre- and postmenopausal women
Authors: Skrzypczak Magdalena , Szwed Anita , Pawlińska-Chmara Romana , Skrzypulec Violetta
Published: January 2008

The main goal of this study was to determine whether and how values of the BMI, WHR and W/Ht indicators change in pre- and postmenopausal women. The tested group consisted of 10,216 women aged 25-95 years. Data were collected during the national campaign "Fighting Obesity", organized by Hand-Prod Company between 2000-2002 across Poland, when adult women voluntarily filled in a questionnaire and participated in anthropometric measurements. The BMI, WHR and W/Ht values were calculated based on these measurements. The values of the BMI, WHR and W/Ht change with age. However, in each age group postmenopausal women have higher BMI, WHR and W/Ht than premenopausal women. Thus, the results obtained indicate that hormonal changes occurring in the climacterium period cause an increase in the analyzed index values. The BMI used herein is characterized by high accuracy in indicating obesity. Moreover, the WHR and W/Ht are also used as adiposity indicators, which may be useful in assessment of the risk of disease or death caused by hypertension, cardiac diseases, diabetes, or even cancers. However, they should not be used only in relation to obese women, because even a slight increase in visceral obesity, with body mass within normal limits, may contribute to unfavorable changes in the woman's metabolic profile, which in turn, may present a risk of illness.
Fine‐Tuning of Yellow or Red Photo‐ and Electroluminescence of Functional Difluoro‐boradiazaindacene Films
Authors: Bonardi Laure , Kanaan Hani , Camerel Franck , Jolinat Pascale , Retailleau Pascal , Ziessel Raymond
Published: January 2008

The present work describes the synthesis of difluoro‐boradiazaindacenes (Bodipy) functionalized at the central 8‐position by phenylamino moieties easily transformable into phenyl amide scaffoldings. Molecules carrying three linear or branched chains were prepared and characterized. An X‐ray crystal structure for the pivotal trimethoxyphenyl‐Bodipy derivative was determined, and the packing is discussed in terms of molecular interactions; a key feature for the formation of thin films. All of the dyes are thermally stable up to 170 °C but no liquid‐crystalline phases are observed. Reversible reduction and oxidation processes occur around +0.97 and −1.34 V, respectively, versus saturated calomel electrode in solution and the electroactivity and photoluminescence are maintained in thin films produced by vacuum evaporation. Interestingly, two distinct emissions are observed at 550 and 635 nm by electroluminescence of the trimethoxyphenyl‐Bodipy derivative, corresponding to the luminescence of isolated molecules and dimers, respectively. Doping Alq3 films with this Bodipy molecule by vacuum evaporation produces organic light‐emitting diodes (OLEDs) in which very efficient energy transfer from the Alq3 matrix to the Bodipy occurs by a resonance mechanism involving the first Bodipy excited state. Yellow light (550 nm, 344 cd m−2 at 15 V) is emitted at low doping concentration (7 mol %), whereas red light (635 nm, 125 cd m−2 at 15 V) is emitted at higher concentration (19 mol %). Dispersion of the Bodipy into a fluorescent poly(N‐vinylcarbazole) polymer (PVK) (≈3 mol % per repeating unit of PVK) by solution processing exclusively produces yellow emission owing to the isolated Bodipyfluorophore (550 nm, 213 cd m−2 at 15 V). The second excited state of the Bodipy dye is likely involved during energy transfer from the PVK matrix.
Nonfouling biomaterials based on polyethylene oxide‐containing amphiphilic triblock copolymers as surface modifying additives: Synthesis and characterization of copolymers and surface properties of copolymer–polyurethane blends
Authors: Tan J. , L. Brash J.
Published: January 2008

The objective of this work is to develop nonfouling biomaterials by blending polyethylene oxide (PEO)‐containing block copolymers with a polyurethane (PU) matrix; it is expected that the PEO component will migrate to the tissue‐material interface. Three amphiphilic triblock copolymers, PEO‐PU‐PEO, in which the PEO MW was 550 (copolymer 1), 2000 (copolymer 2), and 5000 (copolymer 3), respectively, were synthesized. XPS data showed that the polymer/vacuum interfaces of copolymers 2 and 3 were enriched in the PU block, whereas that of copolymer 1 was enriched in the PEO block. In contact with water, the PEO blocks for all three copolymers migrated to the surface as indicated by water contact angles. Blends of the copolymers with a segmented polyurethane were investigated. Surface enrichment of the copolymers occurred and increased over time up to a limit; the degree of enrichment was dependent on PEO block size and copolymer content. At copolymer content <10%, enrichment decreased with increasing PEO block size. For the copolymer 2 and copolymer 3 blends, enrichment increased with increasing copolymer content; at 20% copolymer the surfaces consisted essentially of pure copolymer. For the copolymer 1 blends, the surface was completely covered by copolymer at content ≥ 1%. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Polymerization of methyl acrylate in the presence of ultrasound and peroxodisulfate

Published: January 2008

A systematic polymerization kinetic study of methyl acrylate with an added initiator, peroxodisulfate, in the presence of low‐power ultrasound was done. The polymerization experiments were conducted at various concentrations of monomer and initiator at different temperatures (303–323 K). The polymerization was found to proceed without an induction period, and the steady state was attained in a fairly short time. The rate of monomer disappearance showed a second‐order dependence on monomer concentration. The chain lengths of the polymer were calculated, and we found that the chain length increased with increasing monomer concentration and decreased with increasing initiator concentration. The reaction scheme proposed is based on the kinetic studies that indicated linear termination by sulfate‐ion‐radical‐incorporating direct reaction between the monomer and the initiator. © 2008 Wiley Periodicals, Inc.

A new strategy for the preparation of well‐dispersed clays in a polymer matrix by a spray‐drying method is presented. Scanning electron microscopy and transmission electron microscopy measurements show that the spray‐drying process produces clay/polymer microspheres in which the clay is trapped in a well‐dispersed state throughout the polymer matrix. The microspheres have been successfully extruded into clay/poly(methyl methacrylate) nanocomposite bulk structures without any perturbation of the well‐dispersed clay nanostructure in the original microspheres. Transmission electron microscopy and small‐angle X‐ray scattering show that the clay particles in the extruded materials range from single platelets to simple tactoids composed of a few stacked clay platelets, indicating an excellent degree of dispersion. The results show that sprayed microspheres are very good precursors for further processing such as extrusion or melt blending with other polymers for bulk nanocomposite fabrication. © 2008 Wiley Periodicals, Inc.

Published: January 2008

Systemic regulation of the cellular processes that produce endochondral elongation and endochondral mineralization during postnatal skeletal maturation are not completely understood. In particular, a mechanism coupling the decline of cellular activity in the bone microenvironment to the onset of sexual maturity remains elusive. The purpose of this study was to empirically integrate the dynamic progression of bone mineral accrual and endochondral elongation as a function of animal age in growing male and female Sprague‐Dawley rats. We used serial dual‐energy X‐ray absorptiometry (DXA) and radiography to study the temporal progression of bone growth and mineral accrual from weaning to adulthood. We observed that skeletal maturation proceeds in a pattern adequately described by the Gompertz function. During this period of growth, we found that serum markers of osteoblastic bone formation declined with age, while osteoclastic bone resorption activity remained unchanged. We also report a slight lag in the age at inflection in the rate of bone mineral accrual relative to the rate of tibial elongation and that both endochondral processes eventually come to asymptotic equilibrium by approximately 20 weeks of age. In addition, we studied tibial growth plate histomorphometry at select time points through 1 year of age. We report that, despite the histologic persistence of physeal cartilage, very little proliferative or elongative activity was measured in this tissue beyond 20 weeks of age. Taken together, these data provide insight to the temporal coordination of postnatal endochondral growth processes. Anat Rec, 291:283–292, 2008. © 2008 Wiley‐Liss, Inc.
The BRET technology and its application to screening assays
Authors: Bacart Johan , Corbel Caroline , Jockers Ralf , Bach Stéphane , Couturier Cyril
Published: January 2008

The bioluminescence resonance energy transfer (BRET) method is based on resonance energy transfer between a light‐emitting enzyme and a fluorescent acceptor. Since its first description in 1999, several versions of BRET have been described using different substrates and energy donor/acceptor couples. Today, BRET is considered as one of the most versatile techniques for studying the dynamics of protein‐protein interactions in living cells. Various studies have applied BRET‐based assays to screen new receptor ligands and inhibitors of disease‐related‐proteases. Inhibitors of protein‐protein interactions are likely to become a new major class of therapeutic drugs, and BRET technology is expected to play an important role in the identification of such compounds. This review describes the original BRET‐based methodology, more recent variants, and potential applications to drug screening.

Published: January 2008

Gas‐to‐liquid (GTL) processes are becoming attractive due to the increasing price of crude oil. Process simulation analysis on the integrated GTL process is essential as part of an extended process integration analysis of the research subjects. The two sub‐process models for the GTL process, i.e., the syngas generation process and the Fischer Tropsch synthesis (FTS) process, are analyzed in detail with ASPEN Plus. The autothermal reforming process (ATR) is analyzed using Aspen Plus based on the Gibbs reactor model, while FTS is simulated with ASPEN Plus based on detailed kinetic models for industrial iron and cobalt catalysts. Integrated GTL processes with iron and cobalt‐based catalysts were simulated using ASPEN Plus. The optimal flowsheet structures were selected for each catalyst based on the overall performance in terms of thermal and carbon efficiency and product distributions. For the cobalt‐based catalyst, the full conversion concept without CO2 removal from the FT tail gas is optimal. On the other hand, the once‐through concept with two series reactors and CO2 removal from raw syngas is considered optimal for the iron‐based catalyst. The thermal efficiency to crude products is likely to be ca. 60 % for the cobalt‐based catalyst, whereas it is in the range of 49–55 % for the iron‐based catalyst. The carbon efficiency using the water‐gas shift reaction is lower using the iron‐based catalyst (61–68 %) than the cobalt‐based catalyst (73–75 %). As expected, the cobalt‐based catalyst is more active and selective, which offers better selectivity towards C5+ (75–79 %). The selectivity towards C5+ for the iron‐based catalyst lies in the range 63–75 %.
