Expertise in Online Markets
Authors: Despotakis Stylianos , Hafalir Isa , Ravi R. , Sayedi Amin
Published: September 2016

We examine the effect of the presence of expert buyers on other buyers, the platform, and the sellers in online markets. We model buyer expertise as the ability to accurately predict the quality, or condition, of an item, modeled as its common value. We show that nonexperts may bid more aggressively, even above their expected valuation, to compensate for their lack of information. As a consequence, we obtain two interesting implications. First, auctions with a “hard close” may generate higher revenue than those with a “soft close.” Second, contrary to the linkage principle, an auction platform may obtain a higher revenue by hiding the item’s common-value information from the buyers. We also consider markets where both auctions and posted prices are available and show that the presence of experts allows the sellers of high-quality items to signal their quality by choosing to sell via auctions.

Bio-Mineralization of Organophosphorous Insecticide-Chlorpyrifos and its Hydrolyzed Product 3,5,6-Trichloro-2-Pyridinol by Staphylococcus Sp. ES-2
Authors: Supreeth M , Raju N. S
Published: August 2016

Application of Chlorpyrifos on agricultural fields to protect crops against pests results in accumulation of it in soil and other environmental samples. The insecticide transform into 3,5,6-Trichloro-2-Pyridinol (TCP) through hydrolysis in soil, which has got antimicrobial property and hence resists its degradation in natural condition. In the current findings, a bacterial isolate capable of mineralizing Chlorpyrifos without accumulation of TCP was isolated from agricultural soil by enrichment method. Based on Morphological, Biochemical Characterization and with Bergey’s Manual comparision, the isolate was identified as Staphylococcus sp. The isolate was found to metabolize chlorpyrifos completely in Mineral salt medium with chlorpyrifos as the sole carbon source. No metabolites of chlorpyrifos were detected in Liquid Chromatography-Mass Spectroscopy (LC-MS) analysis after 7 days of incubation. The novelty of the outcome of the experiment relies on Staphylococcus sp.ES-2 in complete mineralization of chlorpyrifos which can be used as a potential bioaugmenting agent in the chlorpyrifos contaminated sites.

Authors: Mashru H. H , Dwivedi D. K
Published: August 2016

Estimation of Evapotranspiration is important for determining the agro-climatic potential of a particular region, water requirement of field crops, irrigation scheduling and suitability of crops or varieties, which can be grown successfully with the best economic returns and therefore numerous models have been developed for determining evapotranspiration. The performance evaluation of commonly used reference evapotranspiration (ET0) estimation methods like FAO 56 Penman-Monteith, Samani and Hargreaves, Makkink, Blaney Criddle, Jensen-Haise, Priestly-Taylor, FAO 24 radiation and Modified Penman Monteith method based on their accuracy of estimation has been undertaken in this study. The inter-relationship between FAO-56 Penman-Monteith method and other reference evapotranspiration (ET0) estimation method is also determined in this study. The results showed that Blaney Criddle method, Modified Penman method, Jensen-Haise method and Priestly-Taylor method are the alternative methods to Penman-Monteith method for better estimate of ET0 for the Junagadh city of Gujarat, India.
The Use of Cytochrome C Oxidase Enzyme Activity and Immunohistochemistry in Defining Mitochondrial Injury in Kidney Disease
Authors: Zsengellér Zsuzsanna K. , Rosen Seymour
Published: August 2016

The renal biopsy is a dynamic way of looking at renal disease, and tubular elements are an important part of this analysis. The mitochondria in 20 renal biopsies were examined by immunohistochemical (electron transport chain enzyme: cytochrome C oxidase IV [COX IV]) and enzyme histochemical methods (COX), both by light and electron microscopy. The distal convoluted tubules and thick ascending limbs showed the greatest intensity in the COX immunostains and enzyme activity in controls. The degree of mitochondrial COX protein and enzyme activity diminished as the tubules became atrophic. With proximal hypertrophic changes, there was great variation in both COX activity and protein expression. In contrast, in three cases of systemic lupus erythematosus, biopsied for high-grade proteinuria, the activity was consistently upregulated, whereas protein expression remained normal. These unexpected findings of heterogeneous upregulation in hypertrophy and the dyssynchrony of protein expression and activity may indicate mitochondrial dysregulation. Functional electron microscopy showed COX activity delineated by the intense mitochondrial staining in normal or hypertrophic proximal tubules. With atrophic changes, residual small mitochondria with diminished activity could be seen. With mitochondrial size abnormalities (enlargement and irregularity, adefovir toxicity), activity persisted. In the renal biopsy, mitochondrial analysis is feasible utilizing immunohistochemical and enzyme histochemical techniques.
Evaluating Potential Economic Effects of an Industrial Road on Subsistence in North-Central Alaska
Authors: Guettabi Mouhcine , Greenberg Joshua , Little Joseph , Joly Kyle
Published: September 2016

North-central Alaska is one of largest inhabited, roadless areas in North America and, indeed, the world. Access, via a new road, to the Ambler mining district of north-central Alaska has been proposed. To evaluate how new road access might affect subsistence harvest, we used zero inflated negative binomial models to identify factors related to subsistence production at the household level. We found substantial differences in these factors between communities near the proposed road (project zone [PZ] communities) and a comparable set of road accessible communities outside the region (non-project zone [NPZ] communities). Total subsistence production of PZ communities was 1.8 to 2.5 times greater than that of NPZ communities. If the road was opened to the public and subsistence harvest patterns for project zone communities changed to mirror existing non-project zone harvests as a result of the road, the financial cost would be USD $6900–10 500 per household (assuming a $17.64/kg “replacement” cost for subsistence harvests). Taken together, our results suggest that the proposed road should be expected to substantially impact subsistence production in communities that are not currently connected to the road system.
The Geometry of Model Spaces for
Probability-Preserving Actions of Sofic
Groups
Authors: Austin Tim
Published: September 2016

Bowen’s notion of sofic entropy is a powerful invariant for classifying probability-preserving actions
of sofic groups. It can be defined in terms of the covering numbers of certain metric spaces associated
to such an action, the ‘model spaces’.
The metric geometry of these model spaces can exhibit various interesting features, some of which provide
other invariants of the action. This paper explores an approximate connectedness property of the model
spaces, and uses it give a new proof that certain groups admit factors of Bernoulli shifts which are not
Bernoulli. This was originally proved by Popa. Our proof covers fewer examples than his, but provides additional
information about this phenomenon.

New biological treatment targeting Mycobacterium tuberculosis in contaminated wastewater using lysing enzymes coupled to magnetic nanoparticles
Authors: Nguyen Dao Q. , Duong Phuong T. , Nguyen Hieu M. , Nam Nguyen Hoang , Luong Nguyen Hoang , Pham Yen
Published: September 2016

Wastewater from hospitals and facilities that receive patients infected with contagious microorganisms has dense concentrations of these pathogens, which may represent a threat to public health. Thus, proper wastewater treatment to remove these contaminants before discharging to the sewage system has been a great concern to the society. Aside from chemical and physical treatment, biological alternatives have been more widely studied and implemented for wastewater processing to avoid unwanted effects and to lower the costs. This study aimed to use lysing enzymes coupled to magnetic amino nanoparticles functionalized with specific antibodies (NP-NH2-antibody) to treat wastewater contaminated with targeted contagious pathogens, initially with Mycobacterium tuberculosis, a highly persistent bacterium. The generated complexes captured Mycobacterium bovis in Bacillus Calmette-Guérin (BCG; tuberculosis vaccine), which was subsequently lysed by lysozyme and lipase. The result showed that single complexes (functionalized with either enzyme or antibody) worked more efficiently than dual complexes (coupled to both proteins) and the complexes could be stored refrigerated stably for at least two months. The preliminary assessment of this method in treating wastewater model samples spiked with BCG vaccine showed evidence for the bacteria being captured and eliminated. Further optimization is necessary to implement these complexes in treating pathogen-contaminated wastewater.
GPs, nurses and pharmacists as prescribers in primary care: an exploration using the social identity approach / Hausärzte/-innen, Diplomierte Pflegefachpersonen und Apotheker/-innen als Arzneimittelverschreiber/-innen: eine Exploration mit dem Ansatz der Sozialen Identität
Authors: Weiss Marjorie C , Platt Jo , Riley Ruth , Horrocks Susan
Published: September 2016

The social identity approach was used to explore the inter-professional relations between nurse prescribers, pharmacist prescribers and general practitioners (GPs) in primary care in the United Kingdom. We investigated their social identities as prescribers, the influence of social structure in practice settings and the implications for further development of nurse and pharmacist prescribing. Interviews were conducted with 21 GPs, nurse prescribers and pharmacist prescribers in primary care from the south of England. Five themes emerged, including the ambiguous social identity of some nurse and pharmacist prescribers (‘a no man’s land’), constraining social structures (‘the doctor is king’), the content of GPs’ social identity (‘subtle prescribing’), the content of nurse and pharmacists’ social identity (‘more than just competent’) and context (‘engaging with each other’s identities’). At some GP practices, there was a willingness to engage with the different social identities and reframe them within the organisational context of a GP surgery. At these sites, where social identities were respected and supported, the social identity approach offered insight into how the resulting teamwork could lead to a shared practice identity focused on multi-disciplinary working. This research provides evidence of how professional and organisational identities can be enhanced and supported. Further, there is the potential for an intervention using the social identity approach to improve patient care.
Interactive learning: developing an eSimulation portal framework
Authors: Tobail Ayman , Crowe John , Arisha Amr
Published: September 2016

The emerging eLearning paradigm is becoming increasingly used in many academic disciplines. The concept acknowledges learning processes that no longer deploy only traditional teaching methods. It can be argued that today’s third level education students are part of a new virtual era where the blackboard has been replaced by the interactive whiteboard, so more interactive and virtually orientated teaching aids are required to assist in the transition from traditional learning to eLearning. The key objective of this paper is to propose a simulation-based learning framework that integrates web-based simulation and a web content management hierarchy model. Using the highly complex subject of supply chain management as a field of study, the newly developed eSimulation tool allows users to examine various management strategies in real-life scenarios, encourages group work and offers remote access capabilities for distance learning. Interactive learning is facilitated using a web-based portal, enabling instructors to demonstrate the complexity of decisions in multiple criteria environments and also demonstrate the impact of various strategies on performance to the users. eSimulation creates an animated experience and better understanding of the system dynamics of decision-making processes. The portal interface is friendly and, hence, has the potential to be applied in other subject areas.
Change detection in the Cox–Ingersoll–Ross model
Authors: Pap Gyula , Szabó Tamás T.
Published: August 2016

We propose an offline change detection method for the famous
Cox–Ingersoll–Ross model based on a continuous sample.
We develop one- and two-sided testing procedures for both drift parameters of the process.
The test process is based on estimators that are motivated by the discrete time least-squares estimators,
and its asymptotic distribution under the no-change hypothesis is that of a Brownian bridge.
We prove the asymptotic weak consistence of the test, and derive the asymptotic properties of the
change-point estimator under the alternative hypothesis of change at one point in time.

Published: September 2016

El propósito de este estudio fue observar si existían diferencias en la puntuación de la autoestima según el nivel de actividad física (activos-sedentarios) en una muestra de personas adultas mayores. La muestra estuvo compuesta por 26 participantes, hombres y mujeres con una edad promedio de 73±9 años; de estos, un grupo de adultos mayores sedentarios (n = 12) que perteneció al Centro Diurno de Santo Domingo de la Provincia de Heredia y el grupo de personas adultas mayores activos (n=14) que formó parte del proyecto Modulación del Proceso de Envejecimiento del Programa Movimiento para la Vida. Resultados: No se encontraron diferencias significativas en la puntuación según el nivel de actividad física (t=0,931, p = 0,363); sin embargo, sí existieron diferencias significativas en el puntaje de autoestima según el género de las personas adultas mayores (t=-2,255, p = 0,034). Se concluye que el nivel de actividad física no incide en la autoestima y que los hombres adultos mayores poseen un mayor nivel de autoestima que las mujeres adultas mayores.
Uma reflexão sobre a psicose na teoria freudiana
Authors: Freire Joyce M. Gonçalves
Published: August 2016

O objetivo deste artigo é trilhar o movimento do pensamento freudiano em relação à psicose. A princípio, o tema da psicose – em especial a paranóia – é desenvolvido por Freud no interior de sua concepção sobre as neuroses, portanto, no terreno da repressão (Verdrängung) para, posteriormente, encontrar sua especificidade conceitual na rejeição (Verwerfund) e na recusa (Verleugnung), conceitos estes tributários das especulações freudianas sobre o narcisismo e a elaboração da, assim chamada, segunda tópica. É também discutida a questão da dificuldade da clínica freudiana para as psicoses pela impossibilidade da transferência.
Um não cedo demais. Investigações teóricas a respeito da psicossomática e da melancolia de um caso clínico
Authors: Portela Maria Cristina Zandoná
Published: August 2016

O artigo vai abordar, a partir do estudo de um caso clínico, questões relativas à melancolia e à psicossomática. Com relação a esta última, a premissa é de que os fenómenos psicossomáticos podem ser entendidos enquanto efeito do inconsciente sobre o próprio corpo e são inseridos no campo da linguagem. Na ótica lacaniana são vistos enquanto manifestações no simbólico -defeito de filiação simbólica. Importante também neste enfoque é a questão dos significantes com relação à origem dos fenómenos psicossomáticos. Significantes que muitas vezes foram impostos ao sujeito e que não encontram articulação no registro simbólico, sendo o corpo a única possibilidade de inscrição do inconsciente. Com relação à melancolia, além da reação frente a perda do objeto amado, será abordado também aquilo que ficou do objeto, ou seja, aquilo que o sujeito carrega dentro de si como um corpo estranho e que muitas vezes se confunde com si mesmo.
O que é phatos?
Authors: Martins Francisco
Published: August 2016

Por intermédio do estudo da etimologia do termo pathos é apresentado as transformações e sentidos que as concepções concernentes tomaram ao longo do tempo. Inicialmente é mostrado que pathos tomou o sentido principal atual de doença, mal-estar. Porém, é logo esclarecido que pathos na sua origem é principalmente disposição afetiva fundamental, conforme a leitura de Heidegger. É mostrada a importância de pensar a psicopatologia e toda ou qualquer clínica como sendo relacionada à disposição. Neste sentido, a concepção kantiana de pathos como paixão que o sujeito está assujeitado é uma das maneiras que pode tomar a disposição afetiva fundamental. Acrescenta-se que o pathos cartesiano que domina o homem moderno e o fazer clínica como sendo daquele homem que duvida e busca então a certeza diferentemente do pathos grego dominado pelo espanto e pela discursividade. Pathos é pensado como sendo algo inerente ao ser humano e por isso mesmo qualifica o estudo de tudo o que diz respeito a este termo como sendo algo próprio do humano.
O estupor melancólico e o estupor maníaco
Authors: Coura Rubens
Published: August 2016

O Estupor Melancólico e o Estupor Maníaco são quadros clínicos das mais completas apatia e inibição motora, hoje tornados raros devido às intervenções psiquiátricas. Eles parecem corresponder aos pontos da máxima pressão possível da pulsão de morte: dirigida, respectivamente, contra o próprio Eu e contra os objetos – naquele sujeito e naquele período de sua vida. Sendo então o estado clínico do ponto intransponível de toda melancolia e de toda mania, esses dois estupores devem compor um verdadeiro elo perdido entre a melancolia e a mania, para a psicanálise. Se a relíquia de Pierre Fédida é, no luto, o fragmento de permanência daquilo que morreu, o autor propõe a romaria do sujeito ao seu tesourinho de criança como uma imagem regressiva apropriada à melancolia e à mania.
Os transtornos e as dificuldades da alimentação
Authors: Gusmão Martha Hirsch
Published: August 2016

Este texto trata das recentes iniciativas de discussão da classificação dos transtornos da alimentação em bebês e na primeira infância (feeding disorders) e de seu interesse para o campo da psicanálise. A compreensão dos transtornos e dificuldades da alimentação, como uma problemática que envolve a díade mãe-criança, remete-nos aos estudos psicanalíticos das relações objetais precoces e teorias do vínculo. O elemento cuidador encontra-se integrado à etiologia dos transtornos da alimentação. Este trabalho apresenta a proposta de classificação de Irene Chatoor, com ênfase no referencial teórico psicanalítico que permite abordar a díade alimentador-alimentado. A superação da dicotomia orgânico/não-orgânico, em psiquiatria infantil, constitui importante passo no diálogo entre disciplinas afins no campo psicopatológico. O diálogo entre psiquiatria e psicanálise abre um campo de pesquisa de novas formas de intervenção e identificação de fatores de risco e situações clínicas que permitam prevenção e profilaxia.

L’auteur propose d’aborder l’éventuelle “nouveauté” des liens familiaux pour la psyché à partir de ce que des enfants-sujets peuvent en élaborer subjectivement. Il développe l’idée selon laquelle la qualité de l’élaboration subjective des liens de parenté au génogramme est significative de la manière dont le sujet subjective sa position instituée et sa place inconsciente dans le lien avec l’autre. Il ressort au travers d’une situation clinique que les modes de tension entre connaissance et représentation des liens sont significatifs du travail de l’Oedipe chez le sujet.
O risco familiar de câncer de mama: a psicanálise diante da pesquisa genética
Authors: Jardim Luciane Loss
Published: August 2016

A Pesquisa Genética está definitivamente na pauta da ciência deste século. Em poucas ocasiões, porém, foi analisada sob a ótica da psicanálise. Este trabalho assume a perspectiva de abordar o risco familiar de câncer de mama pelo viés psicanalítico. Para tal, avalia a posição de quatro mulheres que se submeteram à pesquisa genética desenvolvida, em nível regional, pelo Instituto da Mama do Rio Grande do Sul, vinculado ao Banco Nacional de DNA, com o intuito de verificar a ocorrência de mutação genética responsável pelo câncer de mama hereditário. Aborda as influências tecnológicas na subjetividade e a posição do sujeito frente à hereditariedade, à herança e à enfermidade. Este trabalho de pesquisa é parte de um estudo denominado “Estudo psicanalítico do adoecer de câncer de mama” que , por sua vez fez parte do projeto mais amplo designado como Projeto do Banco Nacional de DNA, executado junto ao Ministério da Saúde.

Published: August 2016

Abstract Objectives: to analyze the occurrence and predisposing factors for surgical site infection in patients submitted to heart transplantation, evaluating the relationship between cases of infections and the variables related to the patient and the surgical procedure. Method: retrospective cohort study, with review of the medical records of patients older than 18 years submitted to heart transplantation. The correlation between variables was evaluated by using Fisher's exact test and Mann-Whitney-Wilcoxon test. Results: the sample consisted of 86 patients, predominantly men, with severe systemic disease, submitted to extensive preoperative hospitalizations. Signs of surgical site infection were observed in 9.3% of transplanted patients, with five (62.5%) superficial incisional, two (25%) deep and one (12.5%) case of organ/space infection. There was no statistically significant association between the variables related to the patient and the surgery. Conclusion: there was no association between the studied variables and the cases of surgical site infection, possibly due to the small number of cases of infection observed in the sample investigated.
Lianas, tree ferns and understory species: indicators of conservation status in the Brazilian Atlantic Rainforest remnants, southeastern Brazil
Authors: Castello A. C. D. , Coelho S. , Cardoso-Leite E.
Published: August 2016

Abstract Indicators are applied faster and at lower costs than conventional surveys, providing quick and efficient responses that can facilitate protected areas management. Our aim was to select indicators from vegetation to monitor protected areas. For this purpose, we analyzed understory and quantified lianas and tree ferns in protected and non-protected areas, in order to find indicator species. Our study areas are located in Vale do Ribeira, southeastern São Paulo state, Brazil. One of the areas is under two protection categories (IUCN's categories II and V), and the other is a privately owned farm. Lianas with large diameters (> 13 cm) and tree ferns with great heights (> 19 m) were considered indicators of undisturbed areas (protected areas) because their growth is directly related to forest successional stage. Indicator species within the protected area were shade tolerant species, such as Bathysa australis (A.St.-Hil.) K.Schum., whereas outside the protected area were pioneer species, such as Pera glabrata (Schott) Poepp. ex Baill. e Nectandra oppositifolia Ness. All of the suggested indicators can be used in management actions, especially in protected areas, to guarantee forest maintenance and ensure fulfillment of the conservation objectives of these areas.

Performance, Charivari e Política
Authors: Medeiros Maria Beatriz
Published: August 2016

RESUMO Este texto trata de performance, charivari, isto é, manifestação política de rua com sua desorganização necessária, e política. Para tanto, conversa com Amselek, Lacan, Derrida, Agamben e Rancière, discutindo o início: aisthesis, tohu-bohu ou linguagem? Real ou realidade? A performance não é ficção nem representação. Ela não apresenta, ela presenta, presentifica, torna presente algo que antes não estava posto. A arte pode ser ficção. A performance à qual nos referimos não é ficção: ela joga na cara o real irredutível a representações.
Método de determinação de pressões em bacias de dissipação a jusante de vertedores tipo salto esqui
Authors: Buffon Franco Turco , Marques Marcelo Giulian
Published: August 2016

RESUMO Este artigo trata da ação dos jatos formados em vertedouros tipo salto esqui sobre bacias de dissipação tipo fossa pré-escavada, dando especial ênfase às pressões hidrodinâmicas e sua caraterização junto ao fundo da bacia. Para estudar experimentalmente a ação dos jatos nas bacias de dissipação, utilizou-se de um modelo físico construído no Laboratório de Obras Hidráulicas do IPH/UFRGS com ensaios de diferentes vazões e cotas de fossas pré-escavadas. As pressões dinâmicas observadas no modelo físico foram comparadas com as calculadas por meio de metodologia teórica com a finalidade de avaliar a sua aplicação em projetos de engenharia, onde se observou grandes diferenças de magnitude da pressão quando em colchões rasos, e diferenças de distribuição de pressão ao longo do fundo da bacia de dissipação, principalmente quando em colchões profundos. No sentido de ajustar a metodologia aplicada, foi proposta a variação de parâmetros que regulam a forma do bulbo de pressões formado pelo jato e a aplicação de um coeficiente de amortecimento de pressões, sendo que assim foi possível melhorar significativamente a distribuição e a magnitude das pressões calculadas devidas à ação dos jatos no fundo da bacia de dissipação. Os resultados se mostram satisfatórios até determinada distância após o pico de pressão provocado pelo jato, porém após este ponto, os efeitos de ressalto hidráulico prevalecem e devem ser pesquisados em estudos futuros.
Occurrence and risk assessment of parabens and triclosan in surface waters of southern Brazil: a problem of emerging compounds in an emerging country

Published: August 2016

ABSTRACT Parabens and triclosan compounds are widely used in pharmaceutical products, personal care, food and various products of daily use. After use, the final destinations of these contaminants are domestic effluents and the environment if not collected or treated. The objective of this study was to evaluate the presence of parabens and triclosan in environments in a subtropical region, more specifically in the metropolitan region of Curitiba (southern Brazil) and possible effects of these compounds in aquatic environments through risk assessment through the use of risk quotient (RQ). Samples were collected in 20 points for 4 campaigns. For the extraction of the compounds we used the extraction technique of solid phase extraction (SPE). The determination of the compounds was using gas chromatography coupled to mass spectrometry (GC-MS). It was observed high concentrations of parabens, especially MeP (up to 2875 ng L–1). Despite high concentrations of parabens, their presence has a low risk to aquatic organisms. Triclosan has been observed at higher concentrations (415 ng L–1), suggesting once again that these environments are impacted by human action. The RQ assessed that triclosan has a high risk for certain groups of organisms.

Published: August 2016

Abstract: The objective of this work was to compare two types of ovulation inducers - estradiol benzoate (EB group) or prostaglandin F2α (PG group) -, in postpartum dairy cows subjected to timed artificial insemination (TAI). Lactating Holstein-Gir crossbred cows (n=118) with 60 to 120 days of milk production were used in this study. All cows were treated with an intravaginal progesterone-releasing device (CIDR) plus 2 mg of estradiol benzoate (EB) on day 0. The CIDR inserts were removed on day 9, and all cows received 500 µg sodium cloprostenol. Twenty-four hours after CIDR removal, cows were randomly assigned into two treatment groups and were given either 1 mg of EB i.m. (EB group) or 500 µg sodium cloprostenol i.m. (PG group). TAI were performed at 52 to 54 hours, in both EB and PG groups, after CIDR removal. No differences were observed in the ovulation (85.2% vs 72.7%) and pregnancy rates (40.7% vs 38.2%) between the EB and PG groups, respectively. Fertility is similar in the TAI protocols that use prostaglandin F2α or EB to induce ovulation in lactating dairy cows.
Concrete modulus of elasticity assessment using digital image correlation
Authors: SANTOS A. H. A. , PITANGUEIRA R. L. S. , RIBEIRO G. O. , CARRASCO E. V. M.
Published: August 2016

Abstract This paper presents the use of the technique of digital image correlation for obtaining the elasticity modulus of concrete. The proposed system uses a USB microscope that captures images at a rate of five frames per second. The stored data are correlated with the applied loads, and a stress-strain curve is generated to determine the concrete compressive modulus of elasticity. Two different concretes were produced and tested using the proposed system. The results were compared with the results obtained using a traditional strain gauge. It was observed a difference in the range of 4% between the two methods, wherein this difference depends on some parameters in the case of the DIC results, as focal length and a video capture resolution, indicating that DIC technique can be used to obtain mechanical properties of concrete.

Published: August 2016

The Tacaná-Boquerón region (TBR) in Chiapas is considered an area of high biodiversity in Mexico, with a rich but poorly studied orchid flora, which is an important component of the vegetation and threatened by an accelerated rate of deforestation. By means of fieldwork, and the revision of scientific collections and literature, an orchid checklist for the TBR and adjacent areas was made; using geographic information systems the distribution of this orchid flora was analyzed in the study area. From 1,235 records we report 105 genera and 325 species, two of them determined to infraspecific level and two are natural hybrids; nine species were additions to the Mexican flora; 39 species are considered at risk in Mexico; the national distribution of a further 20 species are restricted to the TBR. This orchid flora represents 24 % and 44 % of the national and state orchid species richness, respectively, is the second richest in Mexico, and only surpassed by the region El Momón-Las Margaritas-Montebello (Chiapas). The greatest orchid richness is concentrated between elevations of 500 to 2,499 m, in areas now given over to permanent agriculture (including coffee and cocoa plantations); in primary forest the richness is lower. The Tacaná Volcano Biosphere Reserve is the only protected area in the TBR and the proposal to extend it to the Boquerón peak would promote the protection of the orchid flora growing above 1,000 m in the region. Traditional coffee plantations could be alternative to conserve orchids that grow below 1,600 m.
Journey to the Loss and Fixation of Western Identity in Bernardo Bertullocci’s Movie Adaptation of Sheltering Sky
Authors: Gholi Ahmad , Mousaabad Masoud Ahmadi , Raminnia Maryam
Published: September 2016

Bertullocci in his film adaptation of Sheltering Sky portrays Kit, Port, and Tunner who make a journey to Morocco to escape dehumanizing ambience of post war America. In this movie, Port and Kit’s identities undergo drastic change while the Tunner does not. As a professional writer and the devotee of travel himself, Port immerses himself in traditional Oriental space and gradually melts in it, and his death is the culmination of this process. His wife, Kit who is initially unable to understand the depth of his relation the Orient, later succumbs to it, and this finds its full expression in her love of the young Belquassim, her psychosis, and her final decline of returning to American Embassy. By contrast, Tunner’s identity remains unchanged because his main object of travel has been winning Kit’s heart rather than seeking philosophical solutions for his soul in the traversed world. Accordingly the current article argues that travel is interconnected to the concept of identity, depending on the characters’ participation and response to the source culture and its environment. Thus, Port and Kit’s identities experience metamorphosis albeit violently for their receptiveness and deep involvement with the alien culture while Tunner’s disengagement and obsession to retrieve Kit from the Orient does not lead to his identity transition.

New optimization method for design of axisymmetrical TIR optical elements generating the prescribed narrow-angle irradiance distribution is presented. The method is based on the developed quick raytracing procedure including approximation of the optical surfaces by a set of truncated cones. As an example the optical element producing uniformly illuminated circular region with angular size of 60° is presented. It was computed and simulated for extended Lambert light source 1x1 mm. The light efficiency of optical element is 91.5 % and the relative root-mean-square error of generated irradiance distribution is less than 5 %.

Analytically and numerically shown, that an optical microelement consisting just two cylindrical zones is useful for sharp focusing of laser radiation if the radius of the central zone is halfwavelength. The numerical calculations executed in approach of a thin element by means of the plane wave expansion method show good accordance with analytical estimations. Also the qualitative accordance is shown on the basis of finite-difference time-domain method in view of three-dimensional structure of an element. Characteristics and features of diffraction of Gaussian beam with linear and circular polarization on a considered element are investigated.

New design of refractive optical element for display backlight systems is presented. The presented design can be used instead of linear light sources (like electroluminescent lamp with cold cathode). It is intended for uniform illumination of two line segments on the diffuse reflector. The problem of computation of optical surface is reduced to integration of a set of two explicit first-order differential equations. Simulation data for backlight unit containing matrix of designed optical elements demonstrates uniform illumination of rectangular area at the distance of 12-16 mm for LED sources. Light efficiency of the presented optical system is more than 94 %.

The problem of reducing the thickness of the lines of contact pattern masks used in the formation of micro-relief of diffractive optical elements (DOEs) and produced by laser ablation of thin films of refractory metals. For contact mask of DOEs on molybdenum films with thickness of 40 nm using a laser ablation patterns recorded with elements of the picture width 0.25–0.3 µm. This is approximately 3 times smaller than the characteristic dimensions, obtained by thermochemical recording chromium films of the same thickness in the standard process. Reactive ion etching in an inductively coupled plasma through a mask was formed micro-relief height up to 300 nm in a quartz substrate. We have shown promising applications of thin films of molybdenum as a metallic mask in the formation of microrelief of DOEs.

Authors:   National Research University Higher School Of Economics – Nizhny Novgorod, Savchenko A.
Published: September 2016

The usage of the probabilistic neural network with homogeneity testing is proposed in image recognition problem. This decision is shown to be optimal in Bayesian terms if the task is formulated as a statistical testing for homogeneity of query and model images' feature sets. The problem of the lack of computing efficiency with many classes and large dimensions of feature set is discovered. The possibility of its overcoming in the case of discrete features is explored by synthesizing the novel recognition criterion with the comparison of the histograms of query and model images. It is shown that a particular case of this criterion is the nearest neighbor rule with popular measures of similarity, namely, chi-square distance and Jensen-Shannon divergence. The results of experimental research in a problem of face recognition with widely used databases (AT&T, JAFFE) are presented. The proposed approach is demonstrated to achieve better recognition accuracy in comparison with conventional solution with reduction the recognition task to the statistical classification.

We analytically and numerically consider action of the generalized lens – a diffractive optical element with arbitrary degree of dependence of a phase function. Special cases of the generalized lens are axicon and a parabolic lens. On the basis of the modified stationary phase method analytical expressions for the axial distribution formed by the generalized lens in paraxial approach are received. Two types of analytical expressions provide high accuracy of calculation in various ranges of a degree of the generalized lens.

We investigate theoretically and experimentally distribution of electric field components in a focal plane at rotation of a plate with p-phase jump placed in the focused beams. We analyze the polarizing sensitivity of the various apertured metalized probes on the basis of comparison of theoretical and experimental results. It is shown, that with growth of diameter of the aperture window of a probe an essential change of sensitivity occurs in favor of transverse components of the electric field and growth of signal transfer factor of a probe.

Published: September 2016

The problem of localization and recognition of road signs is actual for today. Such a system can not only improve safety, compensating the probable human inattention, but it also helps to reduce tiredness, helping drivers keep an eye on the surrounding traffic conditions. This article proposes an efficient algorithm for preprocessing digital images for further detection of road signs in real time. The article considers the possibility of using HSV color space to extract the red. A denoising algorithm was developed to improve the accuracy and speed of detection. Parallel implementation on the GPU was used to remove the noise. The resulting images are best suited for further localization of road signs.
