Varicella Zoster Virus Infection in Neonates
Authors: Petersen Rebecca , Miller Aaron S.
Published: September 2016

Varicella zoster virus (VZV) can cause a spectrum of clinical manifestations in the fetus and neonate, which range from a self-limited exanthema to congenital malformations and/or death. Once a ubiquitous virus in the community, the epidemiology of VZV has dramatically changed in countries that have introduced the varicella vaccine into their routine immunization schedule. Practitioners must be cautioned against complacency with this virus, however, because unrecognized infection can have far-reaching consequences for the expectant mother, fetus, and neonate. VZV should be included in the differential diagnosis of patients who have a vesicular rash. Multiple factors should be considered before providing prophylaxis or treatment to pregnant women or neonates. Depending on the clinical situation, clinicians may need to know the status of maternal immunity, distinguish primary varicella from secondary zoster infection, determine if the neonate has high-risk characteristics (birth weight, gestational age), and be able to estimate the timing of maternal infection. Nosocomial infection can pose a significant risk to hospitalized neonates. Care provider vigilance coupled with appropriate pharmacologic interventions can help mitigate the consequences of this now uncommon viral infection.

Authors: Ghussn Larissa de Souza , De Souza Regiane Máximo
Published: September 2016

A qualidade de vida da população está diretamente ligada ao acesso à saúde. Uma vez ocorrido um chamado de urgência ou emergência aos Serviços de Atendimentos Emergenciais (SAE’s), a resposta rápida a tal demanda é fundamental para minimizar possíveis sequelas decorrentes no quadro dos pacientes. Um SAE importante para a sociedade é o Serviço de Atendimento Móvel de Urgência (SAMU/192), que é um programa do governo federal e tem como finalidade prestar socorro à população em casos de urgência e emergência. Nesse contexto, o tempo médio de resposta ao usuário é de fundamental importância, pois a demora no atendimento pode significar a vida ou a morte de uma pessoa. Devido às restrições orçamentárias, os SAE’s não podem ter um grande número de pessoas e equipamentos. Dessa forma, existe um compromisso evidente entre investimentos, custos operacionais e o nível de serviço oferecido aos usuários. Uma forma objetiva de avaliar o sistema principalmente em períodos de alta demanda é importante para os gestores, a fim de dar subsídios para tomada de decisão. Nesse sentido, os objetivos desse trabalho são: (i) descrever os chamados e os atendimentos do SAMU-Bauru/SP, (ii) aplicar o modelo hipercubo e (iii) obter suas principais medidas de desempenho. Para isso, realizou-se um estudo de caso no Serviço de Atendimento Móvel de Urgência (SAMU) no município de Bauru. A partir dessa análise, foi possível obter as principais medidas de desempenho do SAMU-Bauru/SP.

Social geography of AIDS in Brazil: identifying patterns of regional inequalities
Authors: Teixeira Tatiana Rodrigues de Araujo , Gracie Renata , Malta Monica Siqueira , Bastos Francisco I.
Published: September 2016

The trend towards decline and stabilization of the AIDS epidemic in Brazil should be analyzed carefully, since aggregate data can mask regional or local inequalities in such a large and diverse country. The current study reevaluates the epidemic’s spatial dissemination and the AIDS-related mortality pattern in Brazil. The study considered all AIDS cases diagnosed in individuals over 18 years of age and living in Brazil, as well as AIDS deaths recorded in 1998-2008. Three-year moving average rates were estimated, and a spatial analysis was conducted using a local empirical Bayesian method. The epidemic was only found to be expanding in the North and Northeast regions, while declining in the rest of the country, especially in the Southeast. According to the findings, the apparent stabilization of AIDS mortality tends to mask regional disparities. Social determinants of health and regional disparities should be taken into account in program development and policymaking.

Authors: Poletto Juliana , Harima Helena Aiko , Ferreira Sandra Roberta Gouvea , Gimeno Suely Godoy Agostinho
Published: September 2016

This cross-sectional study aimed to estimate the prevalence of hyperuricemia and associated risk factors among Japanese-Brazilians. We obtained data on demographic, health history, food intake, and laboratory variables. Chi-square and prevalence ratios were used as measures of association. 35.3% of the subjects presented hyperuricemia, which was more frequent in smokers, males, age > 55 years, with co-morbidities, individuals on uric acid-increasing medication, serum creatinine > 1.4mg/dL, high alcohol consumption, and low consumption of milk and dairy products. In the multivariate analysis, the associations remained significant with gender, overweight, central obesity, hypertriglyceridemia, and use of specific drugs. Among males, low intake of saturated fat was associated with hyperuricemia. Individuals with hypertension showed a negative association with dairy product consumption. The high hyperuricemia prevalence suggests that changes in nutritional profile and control of associated co-morbidities could help minimize occurrence of this condition.

Authors: Guibu Ione Aquemi , Barros Marilisa Berti de Azevedo , Donalísio Maria Rita , Tayra Ângela , Alves Maria Cecília Goi Porto
Published: September 2016

The aim of this study was to evaluate survival time for AIDS patients 13 years and older in the South and Southeast regions of Brazil, according to socio-demographic, clinical, and epidemiological characteristics. The sample was selected from all cases diagnosed in 1998 and 1999 and notified to the Epidemiological Surveillance System of the National STD/AIDS Program. Use of a questionnaire allowed analyzing 2,091 patient charts. Based on the Kaplan-Meier method, estimated survival was at least 108 months after diagnosis in 59.5% of patients in the Southeast and 59.3% in the South. Cox regression models showed, in both regions, an increase in survival in patients on antiretroviral therapy, those classified as AIDS cases according to the CD4 T-cell criterion, females, and those with more schooling. Other factors associated with longer survival in the Southeast were: white skin color, no history of tuberculosis since the AIDS diagnosis, negative hepatitis B serology, and access to a multidisciplinary health team. In the South, age below 40 years was associated with longer survival.
Modelling the effect of tufted yarns in composite T-joints
Authors: Wang Ying , Soutis Constantinos
Published: September 2016

This paper presents a finite-element (FE) simulation of the mechanical response of a composite T-joint subjected to tensile (pull-out) loading. The FE model includes an analysis of the effect of tufted yarns and interlaminar properties on the ultimate load to failure and a comparison between the full and strip FE model. The FE results show that the ultimate load to failure increases when the tufted yarns are introduced. The tufted configuration increases the deflection capacity of the T-joint, and therefore more energy is required to cause ultimate failure. The FE prediction was validated using experimental data for E-glass fibre/epoxy T-joints.

Published: September 2016

Sulfate attack on cement-stabilised soil is a durability problem which is directly related to the sustainability of the foundations. In this study, an experimental framework was established to evaluate the effects of sulfate attack on the strength and penetrability properties of cement-stabilised kaolin clay. Specimens incorporating ordinary Portland, pozzolanic and sulfate-resistant cements were compacted by standard Proctor effort, later cured for 1, 7, 28 and 90 d. Sodium and magnesium sulfates were used at concentrations of 0·3, 0·5 and 1%. At the end of the curing periods, the strength and penetrability characteristics of specimens were determined by conducting unconfined compressive strength and chloride-ion penetration tests. The results revealed that increase in cement content and curing time led to evident increase in strength and decrease in penetrability. Moreover, magnesium sulfate salt adversely affected hydration bonding between soil and cement in stabilised specimens. Increase in cement content caused increases in unconfined compressive strength; however, the rate of strength gain decreased in specimens exposed to sulfate attack. After 7 d of curing, the penetrability of specimens incorporating normal Portland cement is lower compared with that of other specimens including other types of cements; nevertheless, the reverse situation is valid after 28-d curing.
DEMOCRACIA DE CIDADÃOS PROPRIETÁRIOS E O DEBATE IMPOSTO DE RENDA VERSUS REGRAS LEGAIS
Authors: Zanitelli Leandro Martins
Published: September 2016

Rawls contrasta dois tipos de regime institucional, o “capitalismo de bem-estar” e a “democracia de cidadãos proprietários”. O segundo se diferencia do primeiro por procurar atender a um certo ideal pre-distributivo, dispersando o capital (tanto material quanto humano) de maneira a que as relações de mercado sejam travadas em pé de mais aproximada igualdade. O trabalho examina a relação entre a democracia de cidadãos proprietários e o debate imposto de renda versus regras legais como meio de distribuição. Uma questão, respondida negativamente, é se a preferência pela democracia de cidadãos proprietários em relação ao capitalismo de bem-estar tem alguma influência sobre o referido debate e, em particular, sobre a opinião tradicional acerca da superioridade do imposto de renda como meio distributivo. Outra questão é saber se certas críticas a essa opinião tradicional, que chamam a atenção para as dificuldades da distribuição baseada em regras tributárias, é relevante para a democracia de cidadãos proprietários. A resposta, nesse caso, é positiva. A fragilidade dos meios fiscais de distribuição convida a pensar em estratégias para a realização de uma democracia de cidadãos proprietários em que a dispersão do capital, ao invés de ser conseguida exclusivamente mediante transferências, seja assegurada por diferentes partes do sistema de direitos de propriedade.

Phase Field Model for Solidification with Boundary Interface Interaction
Authors: Liao Jie
Published: September 2016

By incorporation the surface free energy in the free energy functional, a phase field model for solidification with boundary interface intersection is developed. In this model, the bulk equation is appropriately modified to account for the presence of heat diffusion inside the diffuse interface, and a relaxation boundary condition for the phase field variable is introduced to balance the interface energy and boundary surface energy in the multiphase contact region. The asymptotic analysis is applied on the phase field model to yield the free interface problem with dynamic contact point condition.
Analysis of MHD Forced Convective Flow of Variable Fluid Properties over a Saturated Porous Medium with Thermal Radiation Effect
Authors: Adegbie Kolawole Sunday , Fagbade Adeyemi Isaiah
Published: September 2016

The present paper addresses the problem of MHD forced convective flow in a fluid saturated porous medium with Brinkman-Forchheimer model, which is an important physical phenomena in engineering applications. The paper extends the previous models to account for effects of variable fluid properties on the forced convective flow through a porous medium in the presence of radiative heat loss using bivariate spectral relaxation method (BSRM). The dynamic viscosity and thermal conductivity of the newtonian fluid are assumed to vary linearly respectively, with temperature whereas the contribution of thermal radiative heat loss is based on Rosseland diffussion approximation. The flow model is described and expressed in form of a highly coupled nonlinear system of partial differential equations. The method of solution BSRM as proposed by Motsa [25] seeks to decouple the original system of PDEs to form a sequence of equations that can be solved in a computationally efficient manner. BSRM is an approach that applies spectral collocation independently in all underlying independent variable is executed to obtain approximate solutions of the problem. The proposed algorithm is supposed to be a very accurate, convergent and very effective in generating numerical results. The results obtained show a significant effects of the flow control parameters on the fluid velocity and temperature respectively. Consequently, the wall shear stress and local heat transfer rate of the present paper are compared with the available results in literatures. Remarkable impacts and a good agreement are found.

The diffraction of a 2D optical beam upon a multilayer Bragg structure is considered. It is shown that phase-shifted Bragg grating can perform spatial integration in transmission of a 2D incident beam in the vicinity of the angular frequency associated with the excitation of a quasi-guided mode confined to the defect layer. The integration is fulfilled with an exponential weight function which fades away as the quality factor of the resonance increases. Beam propagation simulation results are in close agreement with provided theoretical description.

All well-known nonparaxial accelerating two-dimensional light beams propagate along curve trajectories, which do not bend more than a semicircle. In a recent paper, Optics Express 22, 7124 (2014) authors suggest to use additional mirror to generate an accelerating beam with its trajectory bending more than a semicircle, but less than the entire circle. In this paper, we show how to create two-dimensional light field with power flow circulating along a circle (ring). In addition, we consider accelerating nonparaxial asymmetric two-dimensional Bessel beams, which can be obtained from the conventional two-dimensional Bessel beam by complex displacement of the beam center. Simulation shown that with increasing asymmetry parameter curved path of the Bessel beam is shortened, but the relative magnitude of the side lobes (compared to the central lobe) simultaneously decreases.
Spiral light fields in the form of closed curves as generalization of laguerre-gaussian beams

Published: September 2016

In this paper we provide a numerically obtained result for analytical solution for the problem of monochromatic nonparaxial Gaussian beam diffraction by uniform dielectric cylinder, which yields a focal spot outside the cylinder with linear sizes twice less than the diffraction limit in the free space in case of cylinder radius comparable with the wavelength. Although the radius of cylinder is only two times larger than the wavelength, the produced intensity in focal spot is 48 times larger than the maximal intensity of incident Gaussian beam. Two percent deviation from the resonant radius (for a fixed wavelength) causes the focal spot increase in half, and the resulted intensity in focal spot drop to value of 12 times greater than the incident beam intensity. Obtained solution corresponds to the growth of the Bessel function of order 18 coefficient in E-field amplitude Bessel series expansion.

Published: September 2016

Eigenfunctions of the optical operator describing limited imaging system with two lenses are considered under axial symmetry. Resulting functions are analogous to the generalized spheroidal functions which are eigenfunctions of the zero-order Hankel transformation. The expression for eigenfunctions' calculation is obtained using operator representation of the optical system. The influence of the spectrum width on the number of significant eigenvalues is investigated. Decomposition of circular, annular, and Gaussian beam by eigenfunctions is calculated and deviation from the original signals is estimated.

Polarizing and focusing properties of binary Fresnel zone plate (FZP) designed for x-ray was investigated experimentally in visible range for wavelengths 405 nm, 445 nm, and 633 nm. It was shown that peripheral FZP zones rotate the direction of polarization of linearly-polarized incident light on angle equal to doubled angle between incident polarization and relief direction. Illuminated by red and blue linearly polarized light FZP forms 3 focal spots, located on distances that decrease with wavelength decreasing. Minimal focal spot on distance of 105 um above the surface was elliptical and has maximal intensity 9 times larger than the intensity of incident light, and half maximum diameter of diffractive limit of our optical system (2 of wavelength). Peripheral part of FZP forms diffractive limited focal point on distance of 2.8 um that has diameter 9 of wavelength.

Authors:   Samara State Aerospace University, Murzin S.
Published: September 2016

A method of composite nanomaterials synthesis under metal/oxide pulse-periodic laser treatment has been developed on the example of a metal-semiconductor nanocomposite ZnO/Cu. A new approach to the creation of structures of layered composite nanomaterials based on zinc oxide nanofibers is implemented. For the first time for such materials synthesis, heating laser controlled distribution of power density has been used. Air heating of foil brass by pulse-periodic laser treatment intensifies the oxidation of the surface material. Preferable formation of ZnO is caused by a higher oxidation speed of zinc than copper and the zinc diffusion to the surface, as well. The length of zinc oxide nanofibers in the implementation of the selected modes of the laser treatment is less than 5 micrometers.

Published: September 2016

A problem of traffic flow analysis and prediction in city transport network is considered in this paper. The proposed algorithm uses GPS / GLONASS data of public transport location as input. Projecting this information on a transport network graph, as well as using additional filtering, we estimate traffic flow parameters. These parameters are used for short-term (up to 1 hour) prediction of road conditions in the city transport network. There is proposed a new method which consists of several steps to construct prediction. First, the transport graph is divided into a number of subgraphs by a territorial basis. Second, we use a dimension reduction method based on principal components analysis to describe the spatio-temporal distribution of traffic flow condition in the subgraphs. Third, an elementary prediction for each of the subgraphs is formed using the potential functions method with the measure of the subgraphs descriptions closeness introduced by analogy with bilateral filtering and support vector machine. Fourth, the additional elementary prediction is calculated using the known scalar and vector Box–Jenkins time series prediction models. Fifth, we construct the result prediction for each of the subgraphs using an adaptive linear composition of elementary predictions. At last, the traffic flow parameters are calculated as a linear combination of predictions for subgraphs of the city transport network. We have also made experimental investigations of transport network in Samara to evaluate the prediction accuracy of the proposed algorithm. The advantages of the proposed solution in comparison with existing ones are provided.

A method for adjusting directed texture features in biomedical image analysis problems
Authors:   Samara State Aerospace University, Gaidel A. ,   Image Processing Systems Institute, Russian Academy of Sciences
Published: September 2016

As part of the general problem of automatic information feature construction, we considered a particular applied problem of the calculation direction adjustment for the directed texture features intended to diagnose various diseases from digital biomedical images. As feature space quality criteria, we considered the classification accuracy, Bhattacharyya distance and the discriminant analysis criteria. We used random search, a genetic algorithm and simulated annealing as the optimization algorithms. The proposed approach enables a two-fold reduction in the error probability estimation when diagnosing bone tissue X-ray images (from 0.20 to 0.10), also enabling a 45-percent error reduction when diagnosing computed tomography (CT) lung images (from 0.11 to 0.06) in comparison with conventional procedures of selecting from a large number of heterogeneous features.
Conservation theorems for the orbital angular momentum of a superposition of shifted optical vortices
Authors:   Image Processing Systems Institute, Russian Academy of Sciences, Kovalev A. ,   Samara State Aerospace University, Kotlyar V. ,   Image Processing Systems Institute, Russian Academy of Sciences,   Samara State Aerospace University, Kalinkina D. ,   Image Processing Systems Institute, Russian Academy of Sciences,   Samara State Aerospace University
Published: September 2016

We proved two conservation theorems for the orbital angular momentum (OAM) of a superposition of identical optical vortices with an arbitrary radially symmetric shape, integer topological charge n, and arbitrary off-axis shift. The normalized OAM of such a superposition for any real weights equals the OAM of each individual beam contributing to the superposition. If the beam centers are located on a straight line passing through the origin, then, even if the superposition weights are complex, the normalized OAM of the whole superposition equals that of each contributing beam. These theorems allow of generating vortex laser beams with different (not necessarily radially symmetric) intensity distribution, but with the same OAM. The results of numerical simulation are given for superpositions of Bessel beams, Hankel-Bessel, Bessel-Gaussian and Laguerre-Gaussian beams.

Application of a modified supporting quadric method in diffractive optical element design is described. As an example, we compute the eikonal function to focus into a calculator's image represented by a set of points. Properties of the produced image are analyzed using the scalar diffraction theory. It is shown that the proposed method can be used for the design of diffractive optical elements focusing into a continuous required illuminance distribution. Numerical examples also show that the computed eikonal function is a good initial estimate for the iterative Gerchberg-Saxton algorithm.

Published: September 2016

In this article we overview interdisciplinary problems and perform the numerical modeling of a two-way fluid–structure interaction (2FSI) of processes in a gas-rotor-stator system in relation to a prototype compressor stage. Physical, solid-state and mesh-based models are developed. By calculating the 2FSI, we evaluate the interference of a gas-dynamic stream and a deformable rotor blade. The obtained results are discussed. An important finding of the numerical experiment is that a phase-shift of oscillations between the static and dynamic pressure components in optically transparent environment and a phase shift of pressure oscillations in an optically transparent medium and movement in an optically opaque medium are discovered.

An algorithm for determining the spatial coordinates and angular orientation of an object with reference emitters using a single calibrated camera is considered. The algorithm is based on a sequential solution of a perspective-four-point task and more precise definition of reference emitter’s spatial coordinates using the Levenberg – Marquardt optimization method. It is shown that while in the camera field of view there are four reference emitters with a priori known distances between them measured with up to 0.15 mm precision, it is possible to determine the angular orientation of the object in real time with an error less than 20 angular minutes.

Published: September 2016

В статье представлен подход к оценке медицинских услуг на основе синтеза концепций marketing-mix «5Р» и экономики впечатлений. Эмоциональное вовлечение пациентов в процесс потребления порождает повышенный спрос на услуги частной медицины. Феномен эмоциональных продуктов частных медицинских услуг отражает глобальную тенденцию персонализации медицины и сервисизации экономики. Результаты эмпирических исследований подтверждают, что для коммерческой медицинской услуги получение эмоционального удовлетворения от покупки является ведущим фактором потребительского выбора.

Основы государственно-частного партнерства в процессе рационального использования ресурсов особо охраняемых природных территорий
Authors: Салова Любовь Владимировна
Published: September 2016

Новая экономическая реальность показала необходимость поиска новых источников и факторов экономического роста. Одним из таких направлений может выступить рациональное вовлечение ресурсов особо охраняемых природных территорий в хозяйственный оборот, их трансформации в товары и услуги. При этом на сегодняшний день практически отсутствуют научные разработки, связанные с рациональным использованием ресурсов особо охраняемых природных территорий, существующий незначительный опыт в данной области разобщен и не систематизирован. В этой связи в исследовании рассмотрена возможность выстраивания таких процессов на основе государственно-частного партнерства, поскольку форма такого взаимодействия уже зарекомендовала себя с положительной стороны в других областях и сферах деятельности. Такая постановка вопроса отличается сравнительной новизной для отечественной науки, имеет особую актуальность и представляет несомненный интерес для теории и практики. С учетом того, что 2017 год в Российской Федерации объявлен Годом особо охраняемых природных территорий, возникает уникальный случай на фоне всеобщего внимания повысить актуальность обсуждения научных подходов и выработки инструментария по управлению данными процессами.

Authors: Мухаррамова Эльмира Рафаиловна
Published: September 2016

В статье представлена сущность инжиниринга, а также необходимость его использования в строительстве. По результатам проведенного исследования становится понятно, что на сегодняшний день инжиниринг является неотъемлемой частью инвестиционно-строительного процесса, способствует взаимодействию всех участников инвестиционного проекта от составления проектной документации до сдачи в эксплуатацию объекта. В ходе исследования становится ясно, что рассмотренный в статье системный инжиниринг должен быть представлен в виде комплекса наиболее значимых практических вопросов, с целью достижения определенного результата в строительстве. При этом происходит изыскание возможностей максимального использования достижений науки и техники с целью дальнейшего повышения конкурентоспособности самого строительного предприятия. Материалы статьи могут быть использованы и иметь практическую значимость для представителей инвестиционно-строительного комплекса, а также в учебном процессе при подготовке будущих инженеров, экономистов. Также статья может быть полезна для составления методического материала при проведении занятий на курсах повышения квалификации и профессиональной переподготовки сотрудников предприятий инвестиционно-строительного комплекса.

A Amazônia brasileira é um sistema socioecológico complexo que inclui diversos grupos de atores sociaiscujos valores, interesses, trajetórias de ocupação do solo e relações de poder influenciam a tomadade decisão sobre a gestão dos recursos naturais. Uma gestão eficaz exige que os líderes estejampreparados com abordagens e ferramentas para facilitar a colaboração entre esses diversos atoressociais. Este artigo apresenta as lições aprendidas a partir de um curso de especialização no estado deMato Grosso, que teve como objetivo capacitar 20 líderes de universidades, agências governamentais,setor privado e movimento social. Os participantes do curso aplicaram a metodologia de Avaliação deResiliência (AR) para analisar os meios de vida de três grupos de atores dentro do município de Cotriguaçu.Nós descrevemos a pedagogia construtivista utilizada no curso, lições aprendidas na aplicaçãoda AR, e reflexões sobre a utilidade da metodologia para gestão colaborativa socioecológica. Nossaexperiência revela os desafios de engajar adequadamente os atores sociais locais em tais análises eos riscos de realização de ARs lideradas por especialistas em regiões dominadas por elites poderosas,desigualdades, e lacunas de governança.
Voos Xamânicos:
Authors: Silveira Ruth Albernaz
Published: September 2016

“Para encontrar o azul eu uso pássaros...” é uma chave ofertada pelo poeta Manoel de Barros para transver o mundo das materialidades e dos pensamentos. Num sobrevoo na paisagem amazônica rica em formas, cores e pensamentos míticos, podemos nos afetar numa vasta diversidade cultural e biológica. Essa paisagem é manejada pelos povos indígenas desde tempos imemoriais provando que é possível estabelecer relações com a floresta baseadas em práticas de baixo impacto e convivência com os outros seres que ali habitam. A Amazônia é o bioma com maior concentração de vidas co-habitando a mesma região, resultando em sistemas ecológicos e biogeográficos de alta complexidade. Atualmente, sofre grande pressão pelos modelos atuais de ocupação pautados pelo agronegócio que prioriza o capital econômico. É nesse cenário que a artista-bióloga Ruth Albernaz cria sua imagética para propor uma arte sensível que dialogue com a biodiversidade e com o contexto mitológico amazônico. Aqui apresentaremos imagens da série intitulada Voos Xamânicos, que esteve em exposição na Galeria do Sesc Arsenal, em Cuiabá, MT no período de 07 de novembro a 19 de dezembro de 2014, com curadoria da arte-educadora Imara Pizzato Quadros. O tema escolhido foi a palavra-alma “Xamã” por se tratar de um assunto que foi fonte e substrato dessa mostra que apresentou obras inéditas baseadas em pesquisas e experimentações realizadas desde 1996, no campo da Etnoecologia.
