Authors: Nodari Christine Tessele , Bottesini Giovani
Published: July 2015

Os acidentes de trânsito são uma das principais causas de morte e invalidez ao redor do mundo, e estima-se que o elemento humano contribua para a ocorrência de mais de 90% deles, grande parte envolvendo o comportamento dos motoristas. Este artigo apresenta os resultados de uma pesquisa que buscou identificar e classificar medidas de segurança de trânsito conforme sua influência em inibir o cometimento de infrações de trânsito no meio urbano. Para atingir esse objetivo, foram realizadas uma pesquisa qualitativa e uma pesquisa quantitativa. Na primeira, feita por meio de grupos focados, identificaram-se as infrações de trânsito que mais contribuem para os acidentes (embriaguez, excesso de velocidade e avanço de sinal vermelho de semáforo), bem como elementos que auxiliaram na elaboração da pesquisa quantitativa. Esta, por sua vez, consistiu em um questionário autorrelatado aplicado a motoristas de automóvel, no qual verificou-se que as medidas de segurança associadas à restrição de direitos e à possibilidade de ser flagrado pelas autoridades são as que mais influenciam os motoristas a não cometerem infrações

Authors: Alves Bianca Bianchi , Strambi Orlando
Published: July 2015

Resumo: O objetivo do trabalho é identificar variações sistemáticas da importância atribuída por viajantes aéreos aos fatores que influenciam a escolha de modo para acesso terrestre ao Aeroporto Internacional de São Paulo. A análise utilizou dados de uma pesquisa de preferência declarada conduzida com residentes na região viajando para destinos internacionais. Os indivíduos ordenavam 4 alternativas: automóvel, táxi, ônibus expresso existente e um trem expresso proposto, descritas pelos atributos de custo, tempo esperado de viagem e confiabilidade do tempo de viagem, expressa através de uma margem de segurança. Modelos de escolha discreta foram estimados, considerando os efeitos de painel, aninhamento e de inércia. Os resultados indicaram que viajantes a negócios e de alta renda são menos sensíveis ao custo da viagem de acesso ao aeroporto. A importância da confiabilidade do tempo de viagem é maior do que a atribuída ao tempo esperado de viagem e não foi afetada por variações sistemáticas.

Palavras-chave: valor de confiabilidade; acesso terrestre a aeroportos; escolha de modo; modelo logit misto; preferência declarada.

Abstract: The paper analyses systematic variation of tastes and preferences of air travelers regarding the choice of mode for the ground access to the São Paulo International Airport. A stated preference survey was conducted with individuals traveling to international destinations. Each respondent ranked 4 alternatives: auto, taxi, the existing express bus, and a proposed express train. Attributes describing modes were travel cost, average travel time and travel time reliability, expressed as a safety margin – the time period allocated by the individual for arriving at the airport at the preferred time. Discrete mode choice models were estimated, considering panel, nesting and inertia effects. Results indicated that business and higher income travelers are less sensitive to access cost. The importance of the reliability of travel time is higher than the importance of average travel time and is not affected by systematic variations.

Keywords: value of realibility; ground access to airport; modal choice; mixed logit model; stated preference.

Published: July 2015

Os estudos de avaliação relacionados as estruturas de custos de navios tem sido crescentemente reconhecidos como importantes e eficazes instrumentos para um efetivo entendimento dos fatores que dão sustentação a crise que atinge o setor da industria marítima brasileira. Entretanto, apesar de tal reconhecimento, estudos dessa natureza ainda correspondem a um esforço muito reduzido de pesquisa no Brasil. O artigo aqui apresentado teve sua origem em uma tese elaborada e defendida junto a Escola de Políticas Publicas e Governo da UFRJ, onde e proposta uma solução que conceitua a estrutura de custo de uma embarcação de grande porte, detalhando e analisando em seguida seus principais componentes. Segundo a metodologia proposta, a estrutura de custo do navio e considerada como composta por três famílias básicas de custos e não duas, como se observa nas abordagens tradicionais. Os autores acreditam que, desse modo, ha um melhor ajustamento entre a estrutura de custo dos navios, as estruturas organizacionais e os trabalhos de acompanhamento, analise e toma d as de decisão desenvolvidos no âmbito das empresas do setor.

Auditoria da segurança viária
Authors: Nodari Christine Tessele , Lindau Luis Antonio
Published: July 2015

A Auditoria de Segurança Viária - ASV, originada no Reino Unido na década de 80, tem por objetivo diminuir a probabilidade de ocorrência de acidentes de trânsito por meio da realização de vistorias periódicas com foco nas questões de segurança. Este artigo objetiva revisar a ASV, apresentando seus principais conceitos, objetivos, resultados alcançados, aplicabilidade, aspectos legais, custos e benefícios.

A realização de ASV no Brasil é ainda muito incipiente. Por outro lado, em países como a Inglaterra, Dinamarca, Canadá, Austrália e Nova Zelândia, que possuem índices de acidentes substancialmente menores que os brasileiros, a realização de ASV já é prática obrigatória.

A adoção da ASV possibilita economias significativas de recursos. A experiência resultante de duas décadas de condução de ASV sugere que os custos associados à sua execução representam um aumento de apenas 4 a 10% no custo total do projeto. Embora os benefícios gerados sejam de difícil quantificação, estima-se que a condução de ASV resulte em relações benefício-custo na ordem de 15:1; estimativas mais otimistas avaliam essa relação em 20:1. Essas estimativas indicam o grande potencial de retorno social e econômico decorrente da sua aplicação, o que referenda a difusão atual da prática de ASV por diversos países do mundo.

TransCelerate: a global collaboration across biopharmaceutical R&D to accelerate and simplify new medi-cines development
Authors: Marks Lynn
Published: July 2015

As the economic pressures increase on healthcare systems around the world due to aging populations, chronic diseases, expanding patient populations in emerging markets and advances in medical technology, it is crucial that we focus on developing and delivering innovative and quality medicines with true medical value to patients around the world in a more collaborative, quality-focused and cost-effective manner.An important component to this mission across the biopharmaceutical industry is identifying and solving common issues that compromise the success of a clinical development program – the shared pathway to safer and more clinically meaningful medicines. However, subject recruitment challenges, data collection and follow-up issues, identification of high-quality trial sites, and lack of successfully achieving study timelines continue to stress clinical trial operations teams across companies. Although there has been progressing across this range of roadblocks by individual companies, the underlying economics continue to threaten the research and development (R&D) business model.Failure to solve these key issues will affect all parties involved in the clinical trial enterprise: patients, clinical inves-tigators, health authorities, academia, tax-payers and the sponsor companies. The question remains whether a deep and broad collaborative effort that stretches across the clinical development arena—one that is charged with a common goal of improving quality, enhancing the investigator and patient experience, reducing costs and sharing data—can be a catalyst for success. With encouraging signs already realised, the operation of TransCelerate BioPharma Inc., a non-profit organisation created to improve the health of people around the world by accelerating and enhancing the R&D of innovative new therapies will test this premise.

Authors: Bruland Oddbjørn , Færevåg Åshild , Steinsland Ingelin , Liston Glen E. , Sand Knut
Published: July 2015

Snow density is an important measure in hydrology used to convert snow depth to the snow water equivalent (SWE). A model developed by Sturm, Tara and Liston predicts the snow density by using snow depth, the snow age and a snow class defined by the location. In this work this model is extended to include location and seasonal weather-specific variables. The model is named Weather Snow Density Model (Weather SDM). A Bayesian framework is chosen, and the model is fitted to and tested for 4,040 Norwegian snow depth and densities measurements between 1998 and 2011. The final model improved the snow density predictions for the Norwegian data compared to the model of Sturm by up to 50%. Further, the Weather SDM is extended to utilize local year-specific snow density observations (Weather&ObsDensity SDM). This reduced the prediction error an additional 16%, indicating a significant improvement when utilizing information provided by annual snow density measurements.

Authors: Bosiakov Sergei , Mikhasev Gennadi
Published: July 2015

Analytical modeling of stress-strain state of a periodontal ligament in the case of the translational displacement of a tooth root was carried out. The tooth root was assumed as a rigid body. The boundary conditions corresponding to the translational displacement of the root and fixed external surface of the periodontal ligament in the dental alveolus were considered. The system of differential equations describing the periodontal ligament’s plane-strain state induced by the translational motion of the tooth were used as the governing equations. An analytical solution was found for the governing equations in the explicit form. Comparative analysis of the concentrated force generated by the prescribed translational motion of the tooth root was performed using the obtained analytical solution and the model of an incompressible periodontal ligament in the form of a circular paraboloid and hyperboloid. The mathematical model developed in this paper can be used to analyze stresses and strains in the periodontal tissue during orthodontic movement.

Published: July 2015

Иако во минатото не и се придаваше големо значење на оваа бактерија, денес Clostridium difficileе еденод најзначајните агенси кои се поврзуваат со инфекции стекнати во болничката средина. Главната причина заова е големата отпорност наClostridium difficileкако кон антибиотици, така и кон други надворешни влијанија како резултат на способноста за спорулација и секако способноста за лачење на токсини. Во Република Македонија нема податоци за преваленцата на инфекциите со оваа бактерија, ниту е одредена осетливостаи молекуларната карактеризација на изолираните соеви. Анализирајќи 65 рецензирани трудови од оваа проблематика, најдени со пребарување низ базата на податоци од „Пабмед централ“ добиваме интересни сознанија за изолираните соеви наClostridium difficileниз светот, најчесто од хоспитализирани пациенти со антибиотик асоцирана дијареа.Во однос на дијагнозата се препорачува триделниот алгоритам(директен скрининг на глутамат дехидрогеназа-ГДХ, плус фекална детекција на токсините А и В и токсикогена култура) какомошне ефикасен начин за детекција на овие инфекции.Со него би сеопфатиле многу случаи кои би биле пропуштени со другите алгоритми. Можноста од детекција на повеќе случаи го намалува бројот на случаи по пат на трансмисија во болниците, а со тоа и вкупните трошоци како резултат на пролонгирана хоспитализација. Стандардна терапија за инфекции со C. difficilее орално метронидазол или ванкомицин. Пациентите со тешки и рефракторни инфекции со C. difficilеуспешно се третираат интравенски со тигециклин. Тигециклин има најниски вредности за MИК90 за C. difficile, а понатаму следат даптомицин, метронидазоли ванкомицин (1 μg/ml). Клиндамицинот покажал највисоки МИК вредности од сите тестирани антимикробни агенси. Употребата на клиндамицин е поврзана со висок ризик за индуцирање на инфекција со C. difficilе.Во поголемиот број студии, сите соеви биле осетливи на метронидазол, ванкомицин, даптомици и тигециклин, а единствено соевите од риботипот 018 биле осетливи на на моксифлоксацин. Риботипот 018 е најчестиот риботипи сите изолати од овој риботип покажале резистенција на флуорокинолони, што укажува на тоа дека зголемената употреба на овие антибиотици одиграла главна улога во нивната селекција и ширење.Епидемии на инфекции со C. difficile, посебно со токсикогни соеви како риботипот NAP1/027, многу често се пријавувани во Европа, САД и Канада.

Published: July 2015

Long-chain arabinoxylans (LC-AX) are degraded in the colon by intestinal bacteria possessing AX-degrading enzymes, such as bifidobacteria. Enzymatic activity of intestinal bacterial might vary depending on the composition of the gut microbiota. To compare the enzymatic activities of the bacterial gut communities of two healthy individuals (donors D1 and D2), these bacterial communities were inoculated into in vitro model M-SHIME®. Differences in xylanase activities and denaturing gradient gel electrophoresis profiles, in particular a DNA-band corresponding with Bifidobacterium longum, were found in the proximal colon vessel. 16S rRNA gene sequencing analysis demonstrated the presence of two different B. longum species in these bacterial communities, showing 99% gene sequence similarity with B. longum NCC2705 and B. longum. subsp. longum KACC 91563, respectively, further referred to as B. longum D1 and B. longum D2. When grown on LC-AX as the sole added energy source, B. longum D2 displayed significantly higher activities of β-xylanase (5.3-fold), β-xylosidase (2.9-fold), and α-arabinofuranosidase (1.5-fold), respectively, compared to B. longum D1. When B. longum D2 was inoculated in the M-SHIME, inoculated with the bacterial gut communities of the individual with low AX-degrading enzyme activities, the β-xylanase activity increased (1.5-fold) in the proximal vessel. We demonstrated the presence of differences in LC-AX degrading enzyme activities of the bacterial gut communities of two individuals in the in vitro M-SHIME model, which could be linked to the presence of a potent AX-degrading B. longum (D2) strain.

Published: July 2015

The purpose of this study was to evaluate changes in kinematic and kinetic gait characteristics due to outsole structure of the shoe. In this experiment, cushioning shoe having cushion for heel (BOSS Corps., Korea) which is designed as a lever, MBT having an unstable rounded shoe (Masai Barefoot Technology, MBT, Swiss) and normal running shoe (Adidas, Germany) were compared. The experiment was performed walking on the straight walkway (10m x 3m) five times with preferred walking speed. 3D motion capture system was used to acquire kinematic and kinetic data using six infrared cameras and two force plates. For comparison among shoes, walking velocity, hip, knee and ankle joint angles (range of motion, trajectory), ground reaction force (loading rate, the decay rate, maximal vertical ground reaction force), and center of mass - center of pressure inclination angle (COM-COP angle) were used. The results showed that there were different effects of types of shoe on lower extremities. Joint angle trajectory of ankle, joint range of motion (ROM) of the hip, and peak force were significantly different among shoe types. MBT provided a decreased impact force. Cushioning shoe provided increased progressive force, decreased loading rate, and decreased COM-COP angle. For further study, it is necessary to analyze additional subjects (i.e., elderly) and long-term effects.

Published: July 2015

Vertical rolling is a vital method for width control in rolling, which has its own deformation characteristic. During the processing, plastic deformation does not go further into center of slab, only in edge where the deformation will be occurred. In this paper, an anti-symmetric parabola is creatively used to describe dog-bone shape and innovatively applied to establish a knematically admissible continuous velocity field for vertical rolling. Based on this field, an analytical form of total deformation power is obtained which is a function of reduction geometric parameters, and friction factor m, as well as parameter of A which is to be determined. With minimization of total power results in rolling forces and torque calculated by this new method is obtained. Copper and aluminum experiments conducted by S.-E.Lundberg are used to verified the results calculated by formula in present paper and compared with those by Lundberg and Duckjoongs’ models. The error is no more than 13%, (average error 7%).

Bayesian Change Detection in the Growing Window Recursive Strategy
Authors: Dokoupil Jakub , Václavek Pavel
Published: July 2015

A novel growing-window recursive algorithm for stochastic system change detection is derived based on the Bayesian inference principle.
Model based detectors can be formalized by two concepts in literature: (a) working in a sliding-window strategy because of time-dependent computational complexity, or (b) running in parallel, each one matched to a certain assumption on a change point. This motivates us to investigate a more refined approach which utilizes all relevant data to catch the next change point. The basic idea is to formulate a distance measure between two probabilities, one confirming the change occurrence and the other confirming no change in the system behavior. This study aims to solve the difficulty of sliding time arguments in the compared probabilities as new data are sequentially obtained. The outcome of this analysis is an algorithm that recognizes the time and magnitude of the change occurrence.

The unique properties of rare earth elements (REE) have resulted in their being crucial to a growing number of emerging technologies. As the demand for REE currently exceeds annual production, the present worldwide crisis for REE will probably continue for the foreseeable future. Hence, it is highly likely that the availability of REE used in the metallurgy of cast iron will be significantly reduced and alternatives to REE usage may have to be developed. Graphite nodules nucleate heterogeneously on particles formed in the melt, having a duplex structure (sulphide as a core and oxide/silicate as a shell). Mg, Ca and REE appear to act in the nucleation first stage, while Si, Al, Mg, REE, Ca, Sr and Ba act predominately in the second stage. Generally, REE are employed in ductile irons to accomplish the following tasks: (a) neutralize tramp elements such as Ti, Pb, Bi, As etc; (b) assist in nodulizing or provide a supplementary effect to Mg to promote spheroidal graphite shapes; (c) assist in nucleating graphite. When anti-nodularising Thielman control factors (K) are less than 0.8, REE are usually not required since there are no trace elements to neutralize. REE are useful for K factors between 0.80 to 1.20 and are mandatory for K factors greater than 1.20. Theilman factors greater than 2.0 will always require REE. When Theilman factors are less than 0.80, REEreslevels of 0.01% are usually more than sufficient for ductile iron production. Three ductile iron inoculation alloys were selected for this research: (a) a conventional Ca bearing 75% FeSi inoculant (Ca-FeSi), used at a high consumption level; (b) an improved conventional Ca-FeSi alloy that incorporated active inoculating elements, such as Ba or REE, used at a medium consumption level, and (c) a combination of a commercial inoculant, such as Ca-FeSi alloy, used with a separate oxy-sulphide inoculant enhancer alloy addition. The last inoculation variant provided the best structural parameters and the lowest consumption level.

During the last decade an increasing number of researchers focused on materials that have at least one dimension in the nanoscale range. That one dimension has immense impact on the physical and chemical properties of the materials, which is mainly due to the large surface to volume ratio. In order to modify the ratio of surface to volume, many shapes can be produced. Each shape is more useful in certain application than in others (e.g. nanowires are more used in sensors then other shapes and nanospheres are more used in medicine).In this paper, nickel nanowires were grown by electrochemical deposition into polycarbonate track etched (PCTE) membrane. The morphology and size of Ni NWs were examined using an Environmental Scanning Electron Microscopy equipped with energy dispersive X-ray spectroscopy.

Published: July 2015

Hip resurfacing arthroplasty is an very interesting and controversial orthopedic concept in the last years [1]. In order to avoid the previous problems associated with the classical hip prosthesis type metal-polyethylene [2], different manufacturer propose the metal-metal prosthesis based on the reproducible quality of manufacturing of metallic components using Co-Cr alloys and better component fixation. Problems that have been encountered to be the reason for failing of the prosthesis can be different (dislocation, femoral neck fractures, vascular damage, avascular necrosis, raised metal ion levels), and could be related to three main aspects: factors related to the patients, surgical intervention and prosthesis [3, 4]. But a very important aspect is the biomaterials used, that will be discussed in the present paper in correlation with biomechanics and clinical aspects. Our study maked on a lot of retrieved BHR prosthesis used in one Romanian orthopaedic clinic present a higher rate of failure than the other similar studies made by other authors [5]. Starting from this point, we analyze carefully many components of the failed BHR prosthesis using stereomicroscopy, scanning electron microscopy (SEM) and EDS. Based on our experimental results especially at the interfaces metal-cement-bone, we identify different potential causes of failure but the main conclusion was that the cementation technique and poor quality of the patient bone are the reasons for most of hip resurfacing prosthesis failure. As future recommendations for the orthopaedic surgeons we could mention the carefully analysis of bone quality for each candidate using advanced techniques like DEXA and a correlation between the bone cement used for prosthesis fixation and the cementation technique.
The SmCo5 Intermetallic Compound Sintering
Authors: Arghir George
Published: July 2015

The SmCo5has three sintering stages using spheres (0.6 – 1.0 mm diameter) at temperatures between 1030 and 1200 °C. During the first stage the neck radius increases as X2~ t for less than 1200 °C temperature, the exponent is 3 at 1200 °C. Interdiffusion is sintering mechanism for exponent of 2. Sm diffuses from inside to the surface, where it is oxidized and oxides fills the neck between the spheres. Co diffuses through the oxides. At 1200 °C the sintering mechanism is evaporation-condensation of Sm. The activation enthalpy of the first stage is 582 kJmol-1for temperatures above 1130 °C and 210 kJmol-1bellow 1130 °C, respectively. The second stage is characterized by a plateau where the neck growth is arrested. The small pores in the neck and in the sphere surface layer (formed during the first stage) shrink. When these pores disappear a continuous α-Co layer forms and the third stage starts. It is essential growth of the neck formed by dense Co layer. The law of sintering is X4~ t. The activation enthalpy (276 kJmol-1at temperatures above 1130 °C) closes the activation enthalpy of Co self-diffusion. This (together with the exponent of 4) suggests that the Co layer plays a role similar to that of a liquid film. Making slight changes in the chemical composition of the alloys and substituting an argon atmosphere to vacuum have no influence or stages and sintering mechanisms.

Rapid developments in telecommunications and digital processing of information are facing the problem of electromagnetic wave pollution and interference. The aim of this article is the characterization at microwave frequencies of composite materials based on silicone rubber. These materials contain 80% siloxane rubber and only 20% powdery feeling like nanocarbon and pyrite cinder. To achieve these objectives were reviewed and selected raw materials and characteristics were determined in a structural material, the electromagnetic attenuation as well as electrically, by making measurements of electrical conductivity of thin layers of polymer matrix composites produced by the doctor blade technique. Starting from sample siloxane rubber, i.e. without additives or filler reinforcement in compression analysis we find that reinforcing agents leads to increased values of the modulus of elasticity in especially for pyrite ashes. For materials analyzed in this paper, measurements were made in the frequency range between (1-18) GHz and have found high attenuation over 45 dB in the case of composite materials with pyrite ash filler. So we can say that this materials can used for shielding against electromagnetic waves in order to protect the human factor. The novelty of the paper consists in the compositions of the specimens and their mechanical and electromagnetic characteristics.
