El modelo de perfeccionismo disposicional 2x2 en la adolescencia: Una comprobación en el contexto de la Educación Física
Authors: Méndez-Giménez Antonio , Cecchini-Estrada José-Antonio , Fernández-Río Javier
Published: September 2015

Se examinó el modelo de perfeccionismo 2x2 en la adolescencia en el contexto de la Educación Física empleando diversas variables dependientes: auto-concepto, afectividad y satisfacción con la vida. Un total de 331 estudiantes de educación secundaria (58.9% varones y 41.1% mujeres; M = 14.29, DT = 1.43) tomó parte en el estudio. Los análisis de regresión jerárquica moderada mostraron que el tipo de Auto-exigencia Puro se asoció a resultados más adaptativos en comparación con el No-perfeccionismo. El de Presión Externa Puro se relacionó con resultados más negativos en comparación con los otros tipos de perfeccionismo. Finalmente, el Perfeccionismo Mixto se asoció a una mejor adaptación psicológica que el tipo Presión Externa Puro, y a una adaptación más débil con respecto al Perfeccionismo Autoexigente Puro.
Breve historia de la Psicología en la ciudad de La Plata (1906-1966).
Authors: Dagfal Alejandro
Published: September 2015

Muy esquemáticamente, este trabajo aborda seis décadas de la historia de la psicología en la ciudad de La Plata (Argentina), que van desde la creación de la Sección Pedagógica en la Universidad Nacional, en 1906, hasta el golpe de estado de 1966, que puso fin al auge de los estudios psicológicos iniciado con la creación de la carrera profesional, en 1958. En ese período, la psicología pasaría por distintas etapas, signadas por oposiciones tales como “naturalismo positivista”/ “humanismo antipositivista”, “formación disciplinar”/ “formación profesional”, “psicología científica” / “psicología psicoanalítica”, etc. El objetivo de este trabajo es dar cuenta de lo sucedido en ese lapso, poniendo el énfasis no sólo en los actores individuales que intervinieron en ese proceso, sino también en los factores institucionales y políticos que constituyeron el contexto. Los métodos utilizados son los tradicionales de la historia, básicamente, la recopilación de fuentes orales, documentales y bibliográficas. Aunque se las haya interpretado desde una perspectiva crítica.
“La inclusión de los padres en el cuadro de la situación analítica”. Familia, disciplinas psi y valores en la Argentina de los cincuenta
Authors: Macchioli Florencia Adriana
Published: September 2015

El trabajo explora la delimitación de una zona de problemas en torno al niño y la familia, entendidos como objeto de intervención psicológica, durante la década de los años cincuenta, en la Argentina. A partir de un caso clínico de Arminda Aberastury publicado en 1957 en la Revista de Psicoanálisis, se abordan varias dimensiones de análisis, desde un abordaje historiográfico que plantea un cruce entre la historia de las disciplinas psi y los valores. Se hace hincapié en el modo en que se vinculan los valores atribuidos al individuo (especialmente al niño) y a la familia, así como los criterios de salud enfermedad, los roles de género masculino-femenino y las implicaciones de estos valores en los saberes y prácticas del período.

Producción de evidencia psicológica en el debate jurídico sobre adopción gay en Colombia
Authors: Moreno Paola
Published: September 2015

La historia de la psicología puede situarse en escenarios aparentemente ajenos al campo. Con el propósito de comprender el desarrollo de la psicología fuera del laboratorio y de los grandes personajes, el presente trabajo estudia los medios por los cuales la producción de conocimiento psicológico se ensambla a la sociedad. Se analiza la producción discursiva de expertos en psicología que participaron durante el 2009 en el debate jurídico sobre adopción gay en Colombia, describiendo la manera en la que la evidencia psicológica es articulada al ámbito jurídico. Se encuentra que la Corte Constitucional configura un escenario que privilegia y promueve la producción de conocimiento psicológico y que los expertos construyen versiones sobre el orden social a través de la evidencia.
Dialogía intergeneracional en la construcción de memorias acerca de la dictadura militar chilena
Authors: Reyes Andreani María José , Cornejo Cancino Marcela , Cruz Contreras María Angélica , Carrillo Constanza , Caviedes Patricio
Published: September 2015

La transmisión de memorias acerca de la violencia política es apremiante en sociedades que han vivido autoritarismos. Este artículo se focaliza en dicho problema, en el contexto de la dictadura militar chilena (1973-1990) y la memoria que actualmente se construye acerca de ella, a 40 años del golpe de Estado. Desde una perspectiva dialógica, se analiza el tipo de relación que se produce entre generaciones cuando hacen memoria de la dictadura militar. Se realizaron 6 grupos de discusión, participando un total de 48 personas convocadas según (a) grupo etario, (b) posición ideológica, (c) nivel socioeconómico y (d) territorio. El análisis discursivo releva la constitución de tres generaciones –protagonista del pasado, protagonista del presente y zona gris– que al hacer memoria de la dictadura adoptan como forma dialógica el debate, no realizando mayores cuestionamientos respecto de los contenidos considerados al momento de construir versiones de dicho pasado en la conversación.
Delitos Sexuales Infanto-Juveniles Perpetrados por Mujeres: Caracterización Y Análisis Fenomenológico en el Contexto Chileno
Authors: Flores Zúñiga Paula Denisse
Published: September 2015

Este artículo presenta una aproximación Exploratoria-Descriptiva fenomenológica a los delitos sexuales cometidos contra niños, niñas y adolescentes por mujeres ofensoras sexuales. A partir de las variables fenomenológicas principales, tales como vínculo víctima-victimaria, víctima, estrategia de victimización, tipo de delito, entre otras, se investigaron a partir de un enfoque cuantitativo, teniendo como fuentes de información expedientes judiciales e informes psicológicos forenses. Los principales hallazgos indican que la mayoría de las víctimas son pre-escolares, tienen un vínculo conocido con la agresora, estando la estrategia de sometimiento y la clase de contacto sexual impuesta por la autora, relacionada con la edad de la víctima. A modo de conclusión se aprecia un vuelco fenomenológico respecto a la ubicación de la agresora en la vida de la víctima, siendo el rol cuidadora de la víctima que cobra importancia.

Propiedades psicométricas de la Escala sobre Ideología de Género en adolescentes colombianos
Authors: Chahín-Pinzón Nicolás , Briñez Blanca Libia
Published: September 2015

El presente estudio tiene como objetivo principal desarrollar una versión adaptada de la Escala de Ideología de Género (EIG) para adolescentes a partir de la original española de 12 ítems para adultos. Inicialmente se ha analizado por docentes y psicólogos si todos los ítems de la versión española se adaptan a las características culturales y lingüísticas de la población adolescente colombiana, de tal forma que el instrumento sea fácilmente comprensible para su aplicación en estas edades. Posteriormente se han verificado las propiedades psicométricas de todos los ítems, eliminando aquellos cuyas propiedades no eran satisfactorias para ambos sexos, obteniéndose una versión final de 9 ítems con una confiabilidad para toda la muestra de =.763, donde el grupo de mujeres ha tenido una mejor confiabilidad que los varones (=.775 vs. =.734). Por otra, la confiabilidad ha sido superior en el grupo de 15 a 17 años en comparación con el de 12 a 14 años (=.779 vs. =.737). En cuanto a los valores de la EIG, las mujeres puntúan más alto que los varones en los dos grupos de edad, con diferencias significativas tanto en el rango de los 12 a 14 años (t=2.44, p<0.05) como en el rango de los 15 a 17 años (t=2.30, p<0.05). Al relacionar los valores de la escala con los puntajes de las variables socio demográficas, se encuentran correlaciones estadísticamente significativas con la edad (r =.130, p<0.05) y con el grado de estudios (r=.204, p<0.01).
Affected Zones in an Aluminum Alloy Frictionally Penetrated by a Blind Rivet
Authors: Min Junying , Li Jingjing , Li Yongqiang , Carlson Blair E. , Lin Jianping
Published: September 2015

Friction stir blind riveting (FSBR), taking the advantages of friction stir processing with blind riveting, is a new joining process for dissimilar materials. This work is the first to employ electron-backscattered diffraction (EBSD) techniques to examine the microstructural evolution in an aluminum alloy sheet (AA6111), which was frictionally penetrated by a rotating blind rivet. The purpose of this work was to develop a basis of microstructural understanding for subsequent investigations into thermal–mechanical modeling and/or mechanical behavior of the joint. Specifically, EBSD observations and microhardness results are identified and helped to characterize in the area close to the blind rivet; a stir zone (SZ), three thermomechanical-affected zones (TMAZs), as well as a heat-affected zone (HAZ). In the TMAZs, the microhardness decreased from above to below that of the base material as the distance to the rivet increased, and the HAZ was softer than the base metal. Fine (∼1 μm) and low aspect ratio grains were characterized in the SZ, and grain size increased as the distance to the rivet increased within the TMAZs. Nearly, no difference was observed in the grain structure between the HAZ and the base material.
Are Canadian Stakeholders Resting on Their Laurels? A Comparative Study of the Athlete Pathway Through the Swedish and Canadian Male Ice Hockey Systems
Authors: Ogden Josh , Edwards Jonathon R.
Published: September 2015

Organizations in a sport system compete against one another while working together to sustain a competitive environment and to provide opportunities for competition at the provincial/state, national, or international level. This paper is a multicase study comparison of the elite sport development systems of Canada and Sweden to explore the differences and similarities between their approaches to the delivery of ice hockey. Semistructured interviews took place with participants from North America and Europe. Additional data came from media articles from Canada and Sweden. Findings revealed six themes/characteristics: the cost of hockey, residential boundaries, the player selection process, skill development, early specialization, and coaching. The results suggest that Canadian and Swedish hockey systems offer two different approaches to elite player development (closed vs. open systems), resulting in different trajectories regarding international success in the World Junior Championships and in the number of players drafted into the National Hockey League.
CENTRIST’S CURSE? AN ELECTORAL COMPETITION MODEL WITH CREDIBILITY CONSTRAINTS
Authors: ERGUN SELIM JÜRGEN
Published: September 2015

I analyze a model of electoral competition in which candidates’ need of credibility restricts their policy choice to a subset of the policy space, their ideology set. I focus on three party competition where candidates care about winning and their share of votes. I show that centrist parties are highly disadvantaged compared to leftist and rightist ones losing the election under a wide range of parameters. I also show that centrist parties’ winning opportunities increase under a run-off system.
Anisotropic dark energy model with a hybrid scale factor
Authors: Mishra B. , Tripathy S. K.
Published: September 2015

Anisotropic dark energy model with dynamic pressure anisotropies along different spatial directions is constructed at the backdrop of a spatially homogeneous diagonal Bianchi type V (BV) spacetime in the framework of General Relativity. A time varying deceleration parameter generating a hybrid scale factor is considered to simulate a cosmic transition from early deceleration to late time acceleration. We found that the pressure anisotropies along the y- and z-axes evolve dynamically and continue along with the cosmic expansion without being subsided even at late times. The anisotropic pressure along the x-axis becomes equal to the mean fluid pressure. At a late phase of cosmic evolution, the model enters into a phantom region. From a statefinder diagnosis, it is found that the model overlaps with [Formula: see text] at late phase of cosmic time.
Buckling and Post-Buckling of Cantilevered Single-Walled Carbon Nanotubes in Bending
Authors: Prasad Matukumilli V. D. , Bhattacharya Baidurya
Published: September 2015

There are various potential applications in which carbon nanotubes (CNTs) may be subjected to bending in a cantilevered configuration leading to buckling which in turn may affect their electrical, electronic as well as load bearing properties. Using atomistic simulations, we study buckling and post-buckling behavior of six single-walled CNTs subjected to bending in cantilever loading (i.e., flexure in addition to shear and axial compression). Starting with small kinks on the compression side corresponding to locations of high strain energy density, ripples form on the tube wall as bending progresses, until the tube flattens maximally at a critical location giving rise to a stable hinge that rotates under continued bending. The critical buckling curvature, locations of initial and stable hinges and rotational properties of the hinge are determined. Beyond the linear elastic region, the rotational stiffness depends on the hinge angle dropping close to zero (at the same angle for each tube) before beginning to rise again, reminiscent of snap-through buckling of shells, a property that can be exploited for sensing and signal amplification applications.

Normal hyperlattices and pure ideals of hyperlattices
Authors: Koguep Blaise B. N. , Lele Celestin , Nganou Jean B.
Published: September 2015

Two main goals are achieved in this article. On the one hand, we introduce the notion of pure ideal in hyperlattices and provide both algebraic and topological characterizations of the notion. On the other hand, we introduce normal hyperlattices, as a natural generalization of normal lattices as treated by Cornish. We obtain both a topological characterization and a characterization in terms of maximal ideals of normal hyperlattices. Finally, we include illustrative examples of pure ideals, normal hyperlattices.

Congenital Insensitivity to Pain without Anhidrosis: Orodental Problems and Management
Authors: Abdullah N. , Fakhruddin Kausar Sadia , Samsudin A. R.
Published: September 2015

This paper reports the case of a 4-year-old male patient who was brought by parents requesting for replacement of multiple missing anterior teeth. The patient suffered from congenital insensitivity to pain without anhidrosis and presented with full blown sequelae of the condition in the form of oral self-mutilation leading to loss of teeth, tongue tip amputation, finger tips destruction, and lower limb wound infections. Dental and orthopaedic treatment consists of local management of oral wound and prevention from further oral and finger injuries that takes the form of dental splints and finger sleeve splints, constant feet coverage with shoes, and behavioural medical therapy. The age of the patient and parents’ education present challenges in managing this condition to avoid morbidity and premature mortality.

Published: September 2015

The analysis of the spatiotemporal trends of precipitation and drought is relevant for the future development and sustainable management of water resources in a given region. In this study, precipitation and Standardized Precipitation Index (SPI) trends were analyzed through applying linear regression, Mann–Kendall, and Spearman’s Rho tests at the 5% significance level. For this goal, meteorological data from 9 meteorological stations in and around Aksu Basin during the period 1960–2010 was used, and two main annual drought periods were detected (1978-1979 and 1983–1986), while the extremely dry years were recorded in 1975 and 1985 at almost all of the stations. The monthly analysis of precipitation series indicates that all stations had increasing trend in July, October, and December, while both increasing and decreasing trends were found in other months. For the seasonal scale, precipitation series had increasing trends in summer and winter. 33% of the stations had the decreasing trend on precipitation in the spring series, and it was 11% in the autumn. At the same time, the SPI-12 values of all stations had the increasing trend. The significant trends were detected at Aheqi, Baicheng, Keping, and Kuche stations.
Moving Clusters within a Memetic Algorithm for Graph Partitioning
Authors: Hwang Inwook , Kim Yong-Hyuk , Yoon Yourim
Published: September 2015

Most memetic algorithms (MAs) for graph partitioning reduce the cut size of partitions using iterative improvement. But this local process considers one vertex at a time and fails to move clusters between subsets when the movement of any single vertex increases cut size, even though moving the whole cluster would reduce it. A new heuristic identifies clusters from the population of locally optimized random partitions that must anyway be created to seed the MA, and as the MA runs it makes beneficial cluster moves. Results on standard benchmark graphs show significant reductions in cut size, in some cases improving on the best result in the literature.
Reactive Oxygen Species Donors Increase the Responsiveness of Dorsal Horn Neurons and Induce Mechanical Hyperalgesia in Rats
Authors: Kim Hee Young , Lee Inhyung , Chun Sang Woo , Kim Hee Kee
Published: September 2015

Our previous studies suggest that reactive oxygen species (ROS) scavengers have analgesic effect on neuropathic pain through spinal mechanisms in the rat. The studies suggest that superoxide in spinal cord is one of important mediators of persistent pain. To test the hypothesis that increase of superoxide-derived intermediates leads to central sensitization and pain, the effects of an intrathecal injection of chemical ROS donors releasing eitherOH∙,OCl-, or H2O2were examined on pain behaviors. Following treatment witht-BOOH (OH∙donor), dorsal horn neuron responses to mechanical stimuli in normal rats and the changes of neuronal excitability were explored on substantia gelatinosa (SG) neurons using whole-cell patch clamping recordings. Intrathecal administration oft-BOOH or NaOCl (OCl-donor), but not H2O2, significantly decreased mechanical thresholds of hind paws. The responses of wide dynamic range neurons to mechanical stimuli increased after a local application oft-BOOH. Thet-BOOH increased the frequency and the amplitude of excitatory postsynaptic potentials, depolarized membrane potential in SG neurons, and increased the frequency of action potentials evoked by depolarizing current pulses. These results suggest that elevated ROS, especiallyOH∙, in the spinal cord sensitized dorsal horn neurons and produced hyperalgesia in normal rats.

Noncrystalline, high surface area magnesium silicate gel was successfully prepared by hydrothermal method. Such product was characterized by BET and XRD to determine surface area 576.4 m2·g−1, average pore width 2.76 nm, and amorphous surface. The adsorption behaviors of Basic Brown and Chrysophenine on magnesium silicate gel were investigated through changing initial concentration, adsorbent dosage, solution pH, contact time, and temperature. The experimental data was analyzed by the adsorption isotherms and kinetics. The results showed the adsorption progress was fast for Basic Brown, and the adsorption equilibrium was finished in 2 h, while the adsorption equilibrium of Chrysophenine was finished in 7 h. Freundlich isotherm model and second-order kinetic models described the adsorption process very well.

Authors: Zhang Huan , He Chunxia , Yu Min , Fu Jingjing
Published: September 2015

Wheat straw/polypropylene composites are green recycled and biomass-based material. After accelerated aging test of the composite was done, practical and effective methods for characterization and extraction of texture feature of microscopic Scanning Electron Microscopy (SEM) images of composites were investigated in this paper, and involved data compression and classification recognition were studied as well. Through Angle Measure Technique (AMT) method, the complexity spectra, MA spectra, of the preprocessed SEM images of the composites were derived and then the first four principal components of MA spectra using Principal Component Analysis (PCA) were extracted accordingly. Two kinds of classifiers based on Extreme Learning Machine (ELM) and Support Vector Machine (SVM) were introduced to classify the SEM images into five different aging periods in this paper. The research results indicate that AMT method is a very novel and effective approach in texture feature characterization and analysis of SEM images of composites and high classification accuracy of SEM images in different aging periods by using intelligent recognition can be reached.
Recognition Code of ZNF191(243-368) and Its Interaction with DNA
Authors: Zhao Dongxin , Huang Zhongxian
Published: September 2015

ZNF191(243-368) is the C-terminal region of ZNF191 which contains a putative DNA-binding domain of four Cys2His2zinc finger motifs. In this study, an expression vector of a fusion protein of ZNF191(243-368) with glutathione-S-transferase (GST) was constructed and transformed intoEscherichia coliBL21. The fusion protein GST-ZNF191(243-368) was expressed using this vector to investigate the protein-DNA binding reaction through an affinity selection strategy on the basis of the binding quality of the zinc finger domain. Results showed that ZNF191(243-368) can selectively bind with sequences and react with genes which contain an AGGG core. However, the recognition mechanism of Cys2His2zinc finger proteins to DNA warrants further investigation.
Manner of Apical Meristem Destruction Affects Growth, Reproduction, and Survival of Sea Oxeye Daisy
Authors: Spirko Lisa S. , Rossi Anthony M.
Published: September 2015

Although herbivory may result in plant death, the mode and timing of damage may produce variable wounding responses in the attacked plant. In this study, effects of different types of apical meristem damage on growth and performance of sea oxeye daisy Borrichia frutescens (L.) DC were compared. Damage involved either clipping or galling of the apical meristem by the gall midge Asphondylia borrichiae Rossi and Strong. Apical dominance was relatively weak before flowering and stronger in short ramets that were shaded by taller neighbors later in the season. Clipped ramets delayed sprouting new stems, and galled ramets sprouted new stems quickly compared to intact ramets, but final stem counts were similar across treatments. Clipping significantly delayed flowering, reduced seed head ripening time, and resulted in fewer seed heads and seeds. Galling did not significantly impact reproduction compared to intact ramets. Nitrogen supplementation significantly increased stem count and seed count and lengthened seed ripening time. Borrichia frutescens responds differently to clipping versus galling by A. borrichiae and better tolerates galling in terms of nonreproductive performance and survival. Galling from A. borrichiae likely prevents Borrichia frutescens from flowering, which suggests resource regulation of meristems by the midge.
Intelligent Context-Aware and Adaptive Interface for Mobile LBS
Authors: Feng Jiangfan , Liu Yanhong
Published: September 2015

Context-aware user interface plays an important role in many human-computer Interaction tasks of location based services. Although spatial models for context-aware systems have been studied extensively, how to locate specific spatial information for users is still not well resolved, which is important in the mobile environment where location based services users are impeded by device limitations. Better context-aware human-computer interaction models of mobile location based services are needed not just to predict performance outcomes, such as whether people will be able to find the information needed to complete a human-computer interaction task, but to understand human processes that interact in spatial query, which will in turn inform the detailed design of better user interfaces in mobile location based services. In this study, a context-aware adaptive model for mobile location based services interface is proposed, which contains three major sections: purpose, adjustment, and adaptation. Based on this model we try to describe the process of user operation and interface adaptation clearly through the dynamic interaction between users and the interface. Then we show how the model applies users’ demands in a complicated environment and suggested the feasibility by the experimental results.
Comment on “Topically Applied Connective Tissue Growth Factor/CCN2 Improves Diabetic Preclinical Cutaneous Wound Healing: Potential Role for CTGF in Human Diabetic Foot Ulcer Healing”
Authors: Li Hongling , Cao Cong , Huang Ai , Man Yi
Published: September 2015

A recent paper in this journal, presented a novel method by topical application of growth factors in stimulating diabetic cutaneous wound healing that caught our attention. We believe that the experimental method in the article is efficient and creative, but it also has some controversies and shortcomings to be discussed. We noted that the authors used “Tegaderm” as a semiocclusive dressing film and stated that it exerted a “splinting effect” on the wound margins and controlled contraction. Indeed, the “Tegaderm” itself can serve as a dressing film to isolate the wound bed with outside environments while the “splinting effect” is mainly achieved by adding silicone splints around the wound. Considering the unique properties of silicone splints and “Tegaderm,” our experimental group propose an alternative method named “combined-suturing” technique that is not only suturing the silicone splints but also securing the “Tegaderm” around the wound. The specific reasons and operative procedures are explained in detail in this letter.

Published: September 2015

Ebola virus disease (EVD) distinguishes its feature as high infectivity and mortality. Thus, it is urgent for governments to draw up emergency plans against Ebola. However, it is hard to predict the possible epidemic situations in practice. Luckily, in recent years, computational experiments based on artificial society appeared, providing a new approach to study the propagation of EVD and analyze the corresponding interventions. Therefore, the rationality of artificial society is the key to the accuracy and reliability of experiment results. Individuals’ behaviors along with travel mode directly affect the propagation among individuals. Firstly, artificial Beijing is reconstructed based on geodemographics and machine learning is involved to optimize individuals’ behaviors. Meanwhile, Ebola course model and propagation model are built, according to the parameters in West Africa. Subsequently, propagation mechanism of EVD is analyzed, epidemic scenario is predicted, and corresponding interventions are presented. Finally, by simulating the emergency responses of Chinese government, the conclusion is finally drawn that Ebola is impossible to outbreak in large scale in the city of Beijing.
Plasticity-Related PKMζSignaling in the Insular Cortex Is Involved in the Modulation of Neuropathic Pain after Nerve Injury

Published: September 2015

The insular cortex (IC) is associated with important functions linked with pain and emotions. According to recent reports, neural plasticity in the brain including the IC can be induced by nerve injury and may contribute to chronic pain. Continuous active kinase, protein kinase Mζ(PKMζ), has been known to maintain the long-term potentiation. This study was conducted to determine the role of PKMζin the IC, which may be involved in the modulation of neuropathic pain. Mechanical allodynia test and immunohistochemistry (IHC) of zif268, an activity-dependent transcription factor required for neuronal plasticity, were performed after nerve injury. Afterζ-pseudosubstrate inhibitory peptide (ZIP, a selective inhibitor of PKMζ) injection, mechanical allodynia test and immunoblotting of PKMζ, phospho-PKMζ(p-PKMζ), and GluR1 and GluR2 were observed. IHC demonstrated that zif268 expression significantly increased in the IC after nerve injury. Mechanical allodynia was significantly decreased by ZIP microinjection into the IC. The analgesic effect lasted for 12 hours. Moreover, the levels of GluR1, GluR2, and p-PKMζwere decreased after ZIP microinjection. These results suggest that peripheral nerve injury induces neural plasticity related to PKMζand that ZIP has potential applications for relieving chronic pain.

Purpose. To investigate the changes of anterior segment after cycloplegia and estimate the association of such changes with the changes of refraction in Chinese school-aged children of myopia, emmetropia, and hyperopia.Methods. 309 children were recruited and eligible subjects were assigned to three groups: hyperopia, emmetropia, or myopia. Cycloplegia was achieved with five cycles of 0.5% tropicamide. The Pentacam system was used to measure the parameters of interest before and after cycloplegia.Results. In the myopic group, the lenses were thinner and the lens position was significantly more posterior than that of the emmetropic and hyperopic groups in the cycloplegic status. The correlations between refraction and lens thickness (age adjusted;r=0.26,P<0.01), and lens position (age adjusted;r=-0.31,P<0.01) were found. After cycloplegia, ACD and ACV significantly increased, while ACA significantly decreased. Changes in refraction, ACD, ACV, and ACA were significantly different among the three groups (P<0.05, all). Changes of refraction were correlated with changes of ACD (r=0.41,P<0.01).Conclusions. Myopia presented thinner lenses and smaller changes of anterior segment and refraction after cycloplegia when compared to emmetropia and hyperopia. Changes of anterior chamber depth were correlated with refraction changes. This may contribute to a better understanding of the relationship between anterior segment and myopia.

We study the momentum distribution of the electrons in an extended periodic Anderson model, where the interaction,Ucf, between itinerant and localized electrons is taken into account. In the symmetric half-filled model, due to the increase of the interorbital interaction, thefelectrons become more and more delocalized, while the itinerancy of conduction electrons decreases. Above a certain value ofUcfthefelectrons become again localized together with the conduction electrons. In the less than half-filled case, we observe thatUcfcauses strong correlations between thefelectrons in the mixed valence regime.

To study accurately the influence of the deformation, stress, and strain of turbine blisk on the performance of aeroengine, the comprehensive reliability analysis of turbine blisk with multiple disciplines and multiple objects was performed based on multiple response surface method (MRSM) and fluid-thermal-solid coupling technique. Firstly, the basic thought of MRSM was introduced. And then the mathematical model of MRSM was established with quadratic polynomial. Finally, the multiple reliability analyses of deformation, stress, and strain of turbine blisk were completed under multiphysical field coupling by the MRSM, and the comprehensive performance of turbine blisk was evaluated. From the reliability analysis, it is demonstrated that the reliability degrees of the deformation, stress, and strain for turbine blisk are 0.9942, 0.9935, 0.9954, and 0.9919, respectively, when the allowable deformation, stress, and strain are 3.7 × 10−3 m, 1.07 × 109 Pa, and 1.12 × 10−2 m/m, respectively; besides, the comprehensive reliability degree of turbine blisk is 0.9919, which basically satisfies the engineering requirement of aeroengine. The efforts of this paper provide a promising approach method for multidiscipline multiobject reliability analysis.

Cardiac fibromas are benign primary tumors composed of connective tissue and fibroblasts. These uncommon tumors are primarily found in the pediatric population, and their prevalence among the adult population is exceedingly rare. We report a case of an adult with nonspecific symptoms, who was subsequently found to have a solitary mass located in the left ventricle. This case highlights an unusual finding in an adult who through various imaging modalities, surgical excision, and immunohistological analysis was found to have a cardiac fibroma.

Authors: Xu Fang , Ju Mu
Published: September 2015

A triband MIMO antenna used for gsm1800/td-scdma/lte/wi-max/wiLan/wifi has been proposed in this paper. The design with the size of 32 m∗73.6 mm is fabricated on FR4 substrate (thickness is 1.6 mm). This antenna consists of two reversed monopole meandered radiators and defected ground structure which work together to achieve impedance match and enhance isolation for all operating bands. According to the subsequent measured results, the working frequency domains are at gsm1800 (1.71 GHz–1.88 GHz), td-scdma (1.88 GHz–2.025 GHz), lte (2.1–2.35, 2.48–2.51), wi-max (3.5 GHz, 5.5 GHz), wiLan (5.725 GHz–5.8 GHz), and wifi (5.8 GHz–5.88 GHz) approximately. Besides, the measured radiation patterns (gain total) are also well at these working frequency domains and the omnidirectional performance has been achieved for the reversed MIMO antenna array. Furthermore, the realized isolation is more than 15 dB, 24.2 dB, and 22 dB at the first, the second, and the third working frequency band, respectively.

The condition monitoring technology and fault diagnosis technology of mechanical equipment played an important role in the modern engineering. Rolling bearing is the most common component of mechanical equipment which sustains and transfers the load. Therefore, fault diagnosis of rolling bearings has great significance. Fractal theory provides an effective method to describe the complexity and irregularity of the vibration signals of rolling bearings. In this paper a novel multifractal fault diagnosis approach based on time-frequency domain signals was proposed. The method and numerical algorithm of Multi-fractal analysis in time-frequency domain were provided. According to grid typeJand order parameterqin algorithm, the value range ofJand the cut-off condition ofqwere optimized based on the effect on the dimension calculation. Simulation experiments demonstrated that the effective signal identification could be complete by multifractal method in time-frequency domain, which is related to the factors such as signal energy and distribution. And the further fault diagnosis experiments of bearings showed that the multifractal method in time-frequency domain can complete the fault diagnosis, such as the fault judgment and fault types. And the fault detection can be done in the early stage of fault. Therefore, the multifractal method in time-frequency domain used in fault diagnosis of bearing is a practicable method.

Published: September 2015

This study is based on determination of the freeze-thaw resistance of air-entrained and non-air-entrained normal strength concrete (NC) and high strength concrete (HSC) produced with fly ash and silica fume according to surface scaling. The procedure allows us to measure the amount of scaling per unit surface area due to a number of well defined freezing and thawing cycles in the presence of deicing salt. The weight loss, surface scaling, moisture uptake, and internal damage were measured after 0 and after every 4th freeze-thaw cycle. The test results showed that the freeze-thaw resistance is influenced directly by the compressive strength property of the concrete. Silica fume significantly reduced the resistance of normal strength concrete against freeze-thaw effect without plasticizing agent. The surface scaling of silica fume concrete without admixture was 22% higher than reference normal concrete.

Women during pregnancy or puerperium are likely to develop Budd-Chiari syndrome (BCS). However, the reported prevalence of pregnancy-related BCS varied considerably among studies. Our study aims to systematically review this issue. Overall, 817 papers were initially identified via the PubMed, EMBASE, China National Knowledge Infrastructure, and Chinese Scientific and Technological Journal databases. Twenty of them were eligible. The prevalence of pregnancy-related BCS varied from 0% to 21.5%. The pooled prevalence was 6.8% (95% CI: 3.9–10.5%) in all BCS patients, 6.3% (95% CI: 3.8–9.4%) in primary BCS patients, and 13.1% (95% CI: 7.1–20.7%) in female BCS patients. Among them, one study was carried out in Africa with a prevalence of 10.6%; 14 studies in Asian countries with a pooled prevalence of 7.1% (95% CI: 3.1–12.6%); and 5 studies in European countries with a pooled prevalence of 5.0% (95% CI: 3.1–7.3%). The pooled prevalence was 6.7% (95% CI: 2.6–12.3%) in studies published before 2005 and 7.3% (95% CI: 4.2–12.5%) in those published after 2005. In conclusion, pregnancy is a relatively common risk factor for BCS, but there is a huge variation in the prevalence among studies. Physicians should be aware of pregnancy-related BCS.
15-Deoxy-Δ12,14-Prostaglandin J2Inhibits Homing of Bone Marrow-Derived Mesenchymal Stem Cells Triggered by Chronic Liver Injury via Redox Pathway

It has been reported that bone marrow-derived mesenchymal stem cells (BMSCs) have capacity to migrate to the damaged liver and contribute to fibrogenesis in chronic liver diseases. 15-Deoxy-Δ12,14-prostaglandin J2(15d-PGJ2), an endogenous ligand for peroxisome proliferator-activated receptor gamma (PPARγ), is considered a new inhibitor of cell migration. However, the actions of 15d-PGJ2on BMSC migration remain unknown. In this study, we investigated the effects of 15d-PGJ2on the migration of BMSCs using a mouse model of chronic liver fibrosis and primary mouse BMSCs. Our results demonstrated thatin vivo, 15d-PGJ2administration inhibited the homing of BMSCs to injured liver by flow cytometric analysis and,in vitro, 15d-PGJ2suppressed primary BMSC migration in a dose-dependent manner determined by Boyden chamber assay. Furthermore, the repressive effect of 15d-PGJ2was blocked by reactive oxygen species (ROS) inhibitor, but not PPARγantagonist, and action of 15d-PGJ2was not reproduced by PPARγsynthetic ligands. In addition, 15d-PGJ2triggered a significant ROS production and cytoskeletal remodeling in BMSCs. In conclusion, our results suggest that 15d-PGJ2plays a crucial role in homing of BMSCs to the injured liver dependent on ROS production, independently of PPARγ, which may represent a new strategy in the treatment of liver fibrosis.

Published: September 2015

Psoriasis manifests as chronic dermatitis and arthritis (PsA) in people. Psoriasis with concurrent PsA is characterized by erythematous, silvery, scaly plaques, especially on the extremities, and concurrent arthritis with enthesitis, tenosynovitis, and dactylitis. To date, no such disease has spontaneously occurred in domestic animals. This case report aims to describe the clinical, radiographic, and histologic appearance of a psoriasis-like dermatitis and psoriatic-like arthritis in a dog. A 4-year-old female spayed pug mix presented for the evaluation of chronic history of hyperkeratotic footpads and deforming arthritis. After ruling out other differential diagnoses and based on the similarity of clinical, radiographic, and histologic findings to human psoriasis and PsA, a tentative diagnosis of psoriasis-like disease was made. Treatment was begun to control pain (tramadol, gabapentin, and carprofen) and psoriatic dermatitis (clobetasol propionate 0.05%, calcipotriene 0.005%, and urea 40% ointment twice daily). Dramatic positive response to treatment was achieved confirming the tentative diagnosis. This case may provide preliminary evidence for the existence of a psoriasis-like condition in dogs and may elucidate treatment options in otherwise refractory cases of chronic dermatitis and polyarthropathy in dogs.
