Effects of Platform Pre-Heating and Thermal-Treatment Strategies on Properties of AlSi10Mg Alloy Processed by Selective Laser Melting
Authors: Casati Riccardo , Hamidi Nasab Milad , Coduri Mauro , Tirelli Valeria , Vedani Maurizio
Published: November 2018

The AlSi10Mg alloy was processed by selective laser melting using both hot- and cold-build platforms. The investigation was aimed at defining suitable platform pre-heating and post-process thermal treatment strategies, taking into consideration the peculiar microstructures generated. Microstructural analyses, differential scanning calorimetry, and high-resolution diffraction from synchrotron radiation, showed that in the cold platform as-built condition, the amount of supersaturated Si was higher than in hot platform samples. The best hardness and tensile performance were achieved upon direct aging from cold platform-printed alloys. The hot platform strategy led to a loss in the aging response, since the long processing times spent at high temperature induced a substantial overaging effect, already in the as-built samples. Finally, the standard T6 temper consisting of post-process solution annealing followed by artificial aging, resulted in higher ductility but lower mechanical strength.

Authors: Du Zhixia , Li Jinhua , Zhang Xiang , Pei Jin , Huang Linfang
Published: November 2018

The quality assessment and discrimination of Panax herbs are very challenging to perform due to the complexity and variability of their chemical compositions. An integrated strategy was established using UHPLC-Q-Exactive/HRMS and HPLC-ESI-MS/MS to achieve an accurate, rapid, and comprehensive qualitative and quantitative analysis of Panax japonicas (PJ), Panax japonicus var. major (PM), and Panax zingiberensis (PZ). Additionally, discrimination among the three species was explored with partial least squares–discriminant analysis (PLS-DA) and orthogonal partial least squares–discriminant analysis (OPLS-DA) score plots. A total of 101 compounds were plausibly or unambiguously identified, including 82 from PJ, 78 from PM, and 67 from PZ. Among them, 16 representative ginsenosides were further quantified in three herbs. A clear discrimination between the three species was observed through a multivariate statistical analysis on the quantitative data. Nine compounds that allowed for discrimination between PJ, PM, and PZ were discovered. Notably, ginsenoside Rf (G-Rf), ginsenoside F3 (G-F3), and chikusetsu saponin IV (CS-IV) were the three most important differential compounds. The research indicated that the integrated LC-MS-based strategy can be applied for the quality assessment and discrimination of the three Panax herbs.
Philanthropy and Human Flourishing in Patristic Theology
Authors: Rhee Helen
Published: November 2018

This article grounds early Christian theologies and practices of philanthropy in their varied complexities in a larger patristic vision of human flourishing. For patristic authors (second to fifth centuries), human flourishing is grounded in God’s creative intent for material creation, including nature and material goods, that are to be shared for common use and common good, and also to be a means of distributive justice. Based on God’s own philanthropia (“love of humanity”, compassionate generosity), when Christians practice it mainly through almsgiving to the poor and sharing, they mirror the original image (eikon) of God, undo their crime of inhumanity, retain a Christian identity and virtue, and thus restore a semblance of God’s creative intent for the common good. This fundamental social virtue, philanthropia, is, in fact, an attendant virtue of salvation (the goal of creation, including humanity), in reversing the effects of the fall and restoring human flourishing. I then examine patristic authors’ presentations of how wealth presents Christians in concrete situations with a unique challenge and opportunity to demonstrate their spiritual state and persevere in their salvation by eliminating vices (e.g., greed) and cultivating virtues (e.g., detachment), and thereby to affirm and confirm their Christian identities. Finally, I explore the institutional aspect of philanthropy in the (post-) Constantinian era as the Christian church took on the task of caring for the poor of the whole Roman society as a result.
A Cyclic Vernier Two-Step TDC for High Input Range Time-of-Flight Sensor Using Startup Time Correction Technique
Authors: Nguyen Van Nhan , Duong Duc Nha , Chung Yunmo , Lee Jong-Wook
Published: November 2018

Herein, we present a low-power cyclic Vernier two-step time-to-digital converter (TDC) that achieves a wide input range with good linearity. Since traditional approaches require a large area or high power to achieve an input range >300 ns, we solve this problem by proposing a simple yet efficient TDC suitable for time-of-flight (TOF) sensors. In previous studies using the cyclic structure, the effect of startup time on the linearity of the TDC is not described. Thus, the achievable linearity has been limited when the TDC is used for applications requiring a high input range. We solve this problem by using a simple yet effective technique to compensate. The proposed technique is realized using (1) digitally-controlled oscillators (DCOs) that have dual frequency control and matched startup time; (2) an alignment detector that performs startup time correction by proper timing control; and (3) a fully symmetric arbiter that precisely detects the instant of edge alignment. To achieve a fine resolution for the cyclic Vernier TDC, we design two closely-matched DCOs with dual frequency control. The alignment detector performs the critical task of cancelling startup time via timing control. The detector is delay-compensated by using a dummy to provide matched loading for the two DCOs. To enhance the detection speed under low power, a current-reuse approach is employed for the arbiter. The TDC is fabricated using a 0.18 μm complementary metal–oxide–semiconductor (CMOS) process in a compact chip area of 0.028 mm2. Measured results show a dynamic range of 355 ns and a resolution of 377 ps. When the result is applied for TOF sensing, it corresponds to a distance range of 53.2 m and a resolution of 5.65 cm. Over a relatively large input range, good linearity is achieved, which is indicated by a DNL of 0.28 LSBrms and an INL of 0.96 LSBrms. The result corresponds to root mean square (RMS) error distance of 5.42 cm. The result is achieved by consuming a relatively low power of 0.65 mW.
Simultaneous Robot–World and Hand–Eye Calibration without a Calibration Object
Authors: Li Wei , Dong Mingli , Lu Naiguang , Lou Xiaoping , Sun Peng
Published: November 2018

An extended robot–world and hand–eye calibration method is proposed in this paper to evaluate the transformation relationship between the camera and robot device. This approach could be performed for mobile or medical robotics applications, where precise, expensive, or unsterile calibration objects, or enough movement space, cannot be made available at the work site. Firstly, a mathematical model is established to formulate the robot-gripper-to-camera rigid transformation and robot-base-to-world rigid transformation using the Kronecker product. Subsequently, a sparse bundle adjustment is introduced for the optimization of robot–world and hand–eye calibration, as well as reconstruction results. Finally, a validation experiment including two kinds of real data sets is designed to demonstrate the effectiveness and accuracy of the proposed approach. The translation relative error of rigid transformation is less than 8/10,000 by a Denso robot in a movement range of 1.3 m × 1.3 m × 1.2 m. The distance measurement mean error after three-dimensional reconstruction is 0.13 mm.
Spatial–Temporal Variations in NO2 and PM2.5 over the Chengdu–Chongqing Economic Zone in China during 2005–2015 Based on Satellite Remote Sensing
Authors: Cai Kun , Zhang Qiushuang , Li Shenshen , Li Yujing , Ge Wei
Published: November 2018

The Chengdu–Chongqing Economic Zone (CCEZ), which is located in southwestern China, is the fourth largest economic zone in China. The rapid economic development of this area has resulted in many environmental problems, including extremely high concentrations of nitrogen dioxide (NO2) and fine particulate matter (PM2.5). However, current ground observations lack spatial and temporal coverage. In this study, satellite remote sensing techniques were used to analyze the variation in NO2 and PM2.5 from 2005 to 2015 in the CCEZ. The Ozone Monitoring Instrument (OMI) and the Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD) product were used to retrieve tropospheric NO2 vertical columns and estimate ground-level PM2.5 concentrations, respectively. Geographically, high NO2 concentrations were mainly located in the northwest of Chengdu and southeast of Chongqing. However, high PM2.5 concentrations were mainly located in the center areas of the basin. The seasonal average NO2 and PM2.5 concentrations were both highest in winter and lowest in summer. The seasonal average NO2 and PM2.5 were as high as 749.33 × 1013 molecules·cm−2 and 132.39 µg·m−3 in winter 2010, respectively. Over 11 years, the annual average NO2 and PM2.5 values in the CCEZ increased initially and then decreased, with 2011 as the inflection point. In 2007, the concentration of NO2 reached its lowest value since 2005, which was 230.15 × 1013 molecules·cm−2, and in 2015, the concentration of PM2.5 reached its lowest value since 2005, which was 26.43 µg·m−3. Our study demonstrates the potential use of satellite remote sensing to compensate for the lack of ground-observed data when quantitatively analyzing the spatial–temporal variations in regional air quality.
A Batteryless, Wireless Strain Sensor Using Resonant Frequency Modulation
Authors: Lee Kyeong Jae , Chou Namsun , Kim Sohee
Published: November 2018

In this study, we demonstrated the feasibility of a wireless strain sensor using resonant frequency modulation through tensile impedance test and wireless sensing test. To achieve a high stretchability, the sensor was fabricated by embedding a copper wire with high conductivity in a silicone rubber with high stretchability, in which the resonant frequency can be modulated according to changes in strain. The characteristics of the sensor and the behavior of wireless sensing were calculated based on equations and simulated using finite element method. As the strain of the sensor increased, the inductance increased, resulting in the modulation of resonant frequency. In experimental measurement, as the strain of the sensor increased from 0% to 110%, its inductance was increased from 192 nH to 220 nH, changed by 14.5%, and the resonant frequency was shifted from 13.56 MHz to 12.72 MHz, decreased by 6.2%. It was demonstrated that using the proposed sensor, strains up to 110% could be detected wirelessly up to a few centimeters.

Authors: Tang Yongli , Lian Huanhuan , Li Lixiang , Wang Xiaojun , Yan Xixi
Published: November 2018

This study investigates the randomness detection of cryptographic algorithms in network security. To effectively test and verify the security of ZigBee protocol in the Internet of Things, the study combines with the characteristics of ZigBee networks, and it rationally organizes and divides test modes based on the binary matrix rank theory test. Then this paper proposes a randomness detection method of ZigBee protocol in a wireless sensor network. The proposed method solves the one-sidedness that the binary matrix rank test simply assesses random sequences by linear correlation. The proposed assessment method can effectively appraise whether the ZigBee protocol has an encryption mechanism and encryption strength. Simulation results show that this method has the characteristics of fewer errors and high reliability.
Method for Handling Massive IoT Traffic in 5G Networks

Published: November 2018

The ever-growing Internet of Things (IoT) data traffic is one of the primary research focuses of future mobile networks. 3rd Generation Partnership Project (3GPP) standards like Long Term Evolution-Advanced (LTE-A) have been designed for broadband services. However, IoT devices are mainly based on narrowband applications. Standards like LTE-A might not provide efficient spectrum utilization when serving IoT applications. The aggregation of IoT data at an intermediate node before transmission can answer the issues of spectral efficiency. The objective of this work is to utilize the low cost 3GPP fixed, inband, layer-3 Relay Node (RN) for integrating IoT traffic into 5G network by multiplexing data packets at the RN before transmission to the Base Station (BS) in the form of large multiplexed packets. Frequency resource blocks can be shared among several devices with this method. An analytical model for this scheme, developed as an r-stage Coxian process, determines the radio resource utilization and system gain achieved. The model is validated by comparing the obtained results with simulation results.
An Efficient Availability Guaranteed Deployment Scheme for IoT Service Chains over Fog-Core Cloud Networks
Authors: Dinh Ngoc-Thanh , Kim Younghan
Published: November 2018

High availability is one of the important requirements of many end-to-end services in the Internet of Things (IoT). This is a critical issue in network function virtualization (NFV) and NFV-enabled service function chaining (SFC) due to hard- and soft-ware failures. Thus, merely mapping primary VNFs is not enough to ensure high availability, especially for SFCs deployed over fog - core cloud networks due to resource limitations of fogs. As a result, additional protection schemes, like VNF redundancy deployments, are required to improve the availability of SFCs to meet predefined requirements. With limited resources of fog instances, a cost-efficient protection scheme is required. This paper proposes a cost-efficient availability guaranteed deployment scheme for IoT services over fog-core cloud networks based on measuring the improvement potential of VNFs for improving the availability of SFCs. In addition, various techniques for redundancy placement for VNFs at the fog layer are also presented. Obtained analysis and simulation results show that the proposed scheme achieves a significant improvement in terms of the cost efficiency and scalability compared to the state-of-the-art approaches.
Star Wars: The Last Jedi, Beauty and the Beast, and Disney’s Commodification of Feminism: A Political Economic Analysis
Authors: Koushik Kailash , Reed Abigail
Published: November 2018

This paper seeks to explore the strategies Hollywood utilizes to capitalize on feminist social movements through replacing hegemonic male characters with female ones or updating traditional stories through a more “feminist” retelling. By analyzing both 2017’s Star Wars: The Last Jedi and Beauty and the Beast as representative of this corporate trend, we critique the ways in which these pseudo-feminist texts not only contribute little to the social conversation surrounding the evolving roles of women and their representations in media through the lenses of critical political economy, feminist political economy, and feminist film criticism. We conclude that creating “feminist” reimaginings of classic narratives ultimately serves to uphold the existing economic structures that maintain social and financial capital within the largest Hollywood studios. Thus, little to no social progress is made through the creation of these retellings.
Stochastic Empty Container Repositioning Problem with CO2 Emission Considerations for an Intermodal Transportation System
Authors: Zhao Yi , Xue Qingwan , Zhang Xi
Published: November 2018

As one of main challenge for carriers, empty container repositioning is subject to various uncertain factors in practice, which causes more operation costs. At the same time, the movements of empty containers can result in air pollution because of the CO2 emission, which has a negative impact on sustainable development. To incorporate environmental and stochastic characteristics of container shipping, in this paper, an empty container repositioning problem, taking into account CO2 emission, stochastic demand, and supply, is introduced in a sea–rail intermodal transportation system. This problem is formulated as a chance-constrained nonlinear integer programming model minimising the expected value of total weighted cost. A sample average approximation method is applied to convert this model into its deterministic equivalents, which is then solved by the proposed two-phase tabu search algorithm. A numerical example is studied to conclude that the stochastic demand and supply lead to more repositioning and CO2 emission-related cost. Total cost, inventory cost, and leasing cost increase with the variabilities of uncertain parameters. We also found that the total cost and other component costs are strongly dependent on the weights of repositioning cost and CO2 emission-related cost. Additionally, the sensitivity analysis is conducted on unit leasing cost.
Diffusion des rayons X par les milieux désordonnés
Authors: Olmer Philippe
Published: November 2018

Il est possible de résoudre le désordre le plus général qui puisse exister dans un cristal en une série d'ondes de déformation caractérisées par leur vecteur d'onde, leur amplitude et leur phase.

Dans l'étude de la diffusion des rayons X par les cristaux perturbés, on montre que la diffusion dans une direction ne fait intervenir qu'un nombre restreint de ces ondes de déformation. La formule que l'on obtient donnant l'intensité diffusée dans un certain angle solide permet de calculer, d'après les données de la diffusion, la valeur des amplitudes de ces ondes de déformation.

L'agitation thermique peut être considérée à part, car aucune relation de phase ne peut se produire entre les deux phénomènes. On donne quelques applications de cette théorie.

Étude sur la radioactivité de quelques roches par l'émulsion photographique
Authors: Coppens René
Published: November 2018

Emploi de l'émulsion photographique pour l'étude de la radioactivité des roches. — Les éléments radioactifs des roches émettent des rayons a dont les trajectoires s'inscrivent dans l'émulsion. — Possibilité de numération des rayons α et de détermination des teneurs en uranium et en thorium.

Étude de la disparition des traces des trajectoires des rayons α et moyens d'y remédier.

Les roches communes examinées (granites, granulites, gneiss, micaschistes...) ont une concentration en uranium moyenne voisine de 7 à 8 10— 3 et une concentration en thorium environ 3 fois plus forte.

L'activité de ces roches est due, en majeure partie (60 à 70 %), à des inclusions dont l'étude minéralogique est en cours. Ces inclusions semblent pouvoir se classer en 4 catégories :

1° à forte teneur en uranium (70 %) ;

2° â forte teneur en thorium (70 %) ;

3° à faible teneur en uranium (quelques unités pour cent) ;

4° à faible teneur en thorium (1 à 2 %).

La radioactivité de ces inclusions n'est pas uniforme et l'étude des sables met en évidence l'existence de petits grains ayant des teneurs inférieures ou supérieures aux précédentes. D'autre part l'évaluation de la radioactivité globale des sables des plages d'une rivière montre une répartition très irrégulière des éléments actifs.
Determining the optical constants of opaque minerals
Authors: Strens Roger G. J.
Published: November 2018

At least four general methods exist for determining both the absorptive (k) and dispersive (n) optical constants of anisotropic crystals. These are the familiar «two media » method, the Kramers-Kronig analysis of reflectance at normal incidence, and the measurement of R, at two or more angles of incidence which may be either above or below the critical angle for total internal reflexion.

In addition to the general methods, there is a large number of special methods applicable to isotropic materials. The most useful of these are ellipsometry and methods D and H of Humphreys-Owen (1961). Other useful techniques include the measurement of n by immersion or minimum deviation, and of k by thin film or diffuse reflectance methods.

The development of the tunable dye laser and of digital signal processing will greatly facilitate the use of oblique incidence methods in particular, and much more use should be made of these, and of Kramers-Kronig analysis, in the future.

L'orthoferrosilite et les roches associées de la région des Gour Oumelalen (N.E. Ahaggar, Algérie)
Authors: Latouche Louis
Published: November 2018

Pyroxenite, almost entirely composed of iron-rich orthopyroxene with very little fayalite and quartz, forms the extremity of a lens of pyroxenites and basic charnockites. This lens is one of a group of numerous bodies of basic and ultrabasic rocks belonging to the charnockitic suite of the Gour Oumelalen (Ahaggar, Algeria), which are surrounded by garnet-sillimanite gneisses and marbles. This orthopyroxenite gives place in few decimeters to a clinopyroxenite with orthoferrosilite and fayalite. Basic charnockite is a norite with brown amphibole and biotite. The interaction between a vein of hypersthene pegmatite and the clinopyroxenite has produced secondary minerals, amphibole (hastingsite) and garnet (almandine). Physical properties of the iron-rich OPX from the "orthoferrosilitite" are given.

Microprobe analyses of ferromagnesian silicates in these rocks permit some estimates, based upon experimental data, of temperature and pressure. The composition of coexisting clinopyroxene-orthopyroxene suggests that temperatures ranged from 800 °C to 860 °C, The composition of orthoferrosilite (OFS 87-92) coexisting with fayalite (Fa 93 -95) applied to various experimental data indicates pressures of 8. 1-8.7 kbar at 860 °C (8-9 kbar at 800 °C).

Temperatures estimated from garnet-biotite geothermometry in gamet-sillimanite gneisses are between 760 °C and 850 °C. The metamorphic pressure, measured from the garnet-plagioclase-sillimanite-quartz equilibrium, is close to 8.5 kbar at 790 °C.

These diverse P-T estimates define the final metamorphic crystallisation conditions as 760 °C-860 °C and 8-9 kbar, which agree well with those recorded from other Proterozoic granulite facies series.
Phénomènes de karstification observés dans une cavité artificielle du Rincón Blanco (Argentine)
Authors: Barredo Silvia P.
Published: November 2018

Le bassin du Rincón Blanco, situé dans la Province de San Juan (Argentine), se caractérise par une sédimentation continentale où alternent des niveaux détritiques, gréseux et argileux. Durant le Tertiaire, des mouvements compressifs ont déformé cette séquence sédimentaire en un étroit synclinal d'axe nord-sud. Les argiles présentent un faciès lacustre et sont riches en éléments carbonatés et organiques. Cette sédimentation lacustre comporte, par ailleurs, des niveaux connus sous le nom "d'ardoises bitumineuses" du Rincón Blanco.

Dans les années 1950 à 1970, elles ont été intensément exploitées, d'où l'existence de galeries artificielles, aujourd'hui abandonnées ; elles recoupent des terrains affectés par de nombreuses microfractures E-W et SE-NW. Ces discontinuités ont favorisé l'infiltration des eaux météoriques à travers les terrains sus-jacents. Ces eaux d'infiltration, après dissolution des carbonates plus ou moins présents dans les différents terrains géologiques, ont entraîné un concrétionnement relativement varié, sous forme de fistuleuses, de stalagmites, d'encroûtements stalagmitiques accompagnés de gours, de perles et de cristaux coalescents. On observe, également, plusieurs formes liées à l'érosion telles des micro-cupules de paroi, de petites coupoles de plafond, et des impacts de gouttes au sol. Ces formes seraient dues à la percolation d'eaux sous-saturées à l'origine de phénomènes de condensation sur les parois.

Des infiltrations, plus importantes, empruntant des fractures ouvertes entraînent des écoulements temporaires, responsables de formes "majeures" d'érosion, tels de petits chenaux et le transport d'éléments détritiques.
Mise en évidence du phénomène du "renard" : les crues exceptionnelles des sources du Boulet-Blagour (Causse de Martel, Lot)

Published: November 2018

Evidence of the " renard " phenomenon during exceptionnal floods of the Boulet-Blagour springs (Causse de Martel, Lot).

Every three or four years there is an exceptional flooding, different from the numerous floods observed each year at the Boulet and Blagour karstic springs. Not only is the intensity of this phenomenal flood different but so is its mechanism. Its interpretation needs the realisation of a reduced model that displays a mechanism similar to the "renard" effect or fluidisation, well known by hydrauliciens (dam construction) and ignored until now by hydrologists.

Published: November 2018

We report here on the use of ethyl nitroacetate as a glycine template to produce α-amino esters. This started with a study of its condensation with various arylacetals to give ethyl 3-aryl-2-nitroacrylates followed by a reduction (NaBH4 and then zinc/HCl) into α-amino esters. The scope of this method was explored as well as an alternative with arylacylals instead. We also focused on various [2 + 3] cycloadditions, one leading to a spiroacetal, which led to the undesired ethyl 5-(benzamidomethyl)isoxazole-3-carboxylate. The addition of ethyl nitroacetate on a 5-methylene-4,5-dihydrooxazole using cerium(IV) ammonium nitrate was also explored and the synthesis of other oxazole-bearing α-amino esters was achieved using gold(I) chemistry.

Published: November 2018

Objective.

Validated gastrointestinal (GI) symptoms scales are used in clinical practice to assess patient-reported GI involvement. We sought to determine whether University of California, Los Angeles (UCLA) GI Tract Questionnaire (GIT) 2.0 Reflux scale, Patient-Reported Outcomes Measurement Information System (PROMIS) Reflux scale, and the Quality of Life in Reflux and Dyspepsia questionnaire (QOLRAD) are sensitive to identifying changes in GI symptoms following therapeutic intervention in participants with systemic sclerosis (SSc) and gastroesophageal reflux disease (GERD).

Methods.

Participants with active GERD were recruited during clinical visits at 6 international SSc centers. Patient-reported outcome surveys and the GI self-reported questionnaire were completed at baseline and again at 4 weeks following a single intervention, and patients were classified as “improved” or “not improved.” Effect size (ES) was calculated to assess the sensitivity to change. ES was interpreted as 0.50–0.79 as moderate effect and ≥ 0.80 as large effect.

Results.

There were 116 participants with SSc and active GERD who enrolled. The average age was 53.8 years and mean disease duration was 12.0 years. The UCLA GIT 2.0 Reflux scale and PROMIS Reflux scale had a significant correlation at baseline (0.61, p < 0.0001), and both instruments correlated with the QOLRAD domains (−0.56 to −0.71). In participants who had the UCLA GIT 2.0, PROMIS Reflux scale, and QOLRAD administered over 2 timepoints (n = 57) and were classified as improved, the ES was large for the UCLA GIT 2.0 and PROMIS Reflux scale, and moderate to large across all QOLRAD domains.

Conclusion.

The UCLA GIT 2.0 Reflux scale, PROMIS Reflux scale, and QOLRAD are sensitive to change and can be included in future clinical trials.

Objective.

To determine barriers and facilitators to the uptake of findings from the Research in Arthritis in Canadian Children emphasizing Outcomes (ReACCh-Out) study into clinical care by pediatric rheumatologists (PR) and allied health professionals (AHP) caring for children with juvenile idiopathic arthritis (JIA) in Canada.

Methods.

PR and AHP participated in this qualitative study through telephone interviews. Interview guides were developed using the Theoretical Domains Framework and focused on the use of information from the ReACCh-Out study in the practice of counseling patients and families. A directed content analysis approach was used for coding.

Results.

Nineteen interviews (8 PR and 11 AHP) were completed. All PR had knowledge of the ReACCh-Out study. Three major themes were identified: (1) both groups are motivated to use information from research in clinical care; (2) volume and emotional effect of information on families are barriers; and (3) specific timepoints in care trigger providing this information. AHP had less knowledge of the ReACCh-Out study, did not feel it was their primary role to provide this information, and have a desire for more opportunity to participate in academic forums related to research.

Conclusion.

Published: November 2018

A numerical computation has been carried out, to investigate the effects of Soret and Dufour numbers on mixed convective heat and mass transfer flow for a steady, two dimensional, incompressible, electrically conducting viscous fluid flow over a semi-infinite vertical plate in a saturated porous medium under the influence of magnetic field (Lorentz force) with variable fluid properties. The physical governing equations for the fluid flow represents in the nonlinear PDE's regime, which are reduced into a system of ODE's using similarity transformation. The numerical computation of shooting technique is adopted to analyze the nature of "velocity, temperature, concentration fields, skin friction, heat and mass transfer coefficients" graphically for uniform permeability (UP) as well as variable permeability (VP) and illustrated for various non-dimensional parameters of the physical model. The results of the numerical scheme are validated and a numerical comparison has been done for a particular case with the available literature in the absence of few physical parameters and found that in good agreement.

Published: November 2018

The paper examines the combined effects of Hall current, buoyancy forces, thermal radiation, thermo-diffusion and fluid rotation on an unsteady hydromagmetic boundary layer flow with heat and mass transfer over an impulsively moving vertical plate embedded in a porous medium. Base on some realistic simplified assumptions, the governing equations of momentum, energy and chemical species concentration are obtained and tackled analytically using Laplace transform technique. The numerical values of primary and secondary fluid velocities, fluid temperature and species concentration are displayed graphically while those of skin friction coefficient, Nusselt number and Sherwood number are presented in tabular form for different values of pertinent flow parameters.

Published: November 2018

An analysis is carried on an unsteady two-dimensional squeezing radiative flow of an incompressible, viscous, electrically conducting fluid in the presence of time-varying transverse magnetic field and chemical reaction. The crux of the analysis centres round, time-varying magnetic field, squeezing of the channel, chemical reaction of diffusing species and radiative heat transfer. These phenomena affect momentum, thermal energy and solutal transport mechanism significantly. The modified governing equations with complex boundary conditions contribute to intricacy of the solution. The Runge-Kutta sixth order integration scheme with shooting technique has been applied to solve the ordinary differential equations under similarity transformations. The analysis reveals that the numerical method applied in the present analysis is as effective and consistent as that of Homotopy Analysis Method (HAM). Further, it is interesting to note that the squeezing of the channel width acts adversely to the resistive force due to the presence of a magnetic field and hence suggests a controlling device to nullify the effect.

Published: November 2018

Context: The assessment of left ventricular ejection fraction (LVEF) is the most important component in prediction and detection of cardiotoxicity in patients undergoing cancer chemotherapy. LVEF may not be sensitive enough to pick the cardiotoxicity early since drop in LVEF occurs in the last and irreversible stage. A 10%–15% early reduction in global longitudinal strain (GLS) by speckle tracking echocardiography proposed to be the earliest indicator of myocardial dysfunction. Aims: The aim of this study was to compare the early detection of cardiotoxicity (at 0 and 3 months) using drop in LVEF with two-dimensional echocardiography (2DE), three-dimensional echocardiography (3DE), and GLS techniques. Settings and Design: This was a prospective cohort study of patients attending cardiooncology clinic in a tertiary care institute. Subjects and Methods: Newly diagnosed 75 cases of cancer of various etiologies, for whom cardiotoxic chemotherapy drugs has to be used, were included from January 2016 to June 2016. Statistical Analysis Used: Data were analyzed with Pearson’s Chi-square test, mean, standard deviation, and 95% confidence interval. Results: A total of 17 (22.6%) subjects out of 75, had drop in LVEF by GLS (<−18.9%) as compared to 5 (6.6%) in 2DE and 7 (9.3%) in 3DE at 3 months with statistically significant P values (P = 0.0001). In the 17 subjects who had significant fall in GLS at 3 months, the mean GLS was −16.17 ± 1.55% with a significant reduction of 13.48% from baseline. Conclusion: Reduction in GLS preceded decrease in ejection fraction. Early detection allows modification of chemotherapeutic regimens and medical intervention preventing the irreversible cardiac damage.

Background: Tobacco has been the arch criminal of most head-and-neck cancers in the world. Many laws have been implemented to control this menace, but still this slow poison persists. Effectiveness of these laws has always been a matter of concern to the authorities. The present study was conducted to observe the compliance of Cigarettes and Other Tobacco Products Act (COTPA) among public places, educational institutions, and tobacco vendors in Bengaluru city. Methodology: A cross-sectional, observational study was done to assess the violations at public places, educational institutions, and tobacco vendors. Violations for Sections 4, 5, 6, and 7 of COTPA were assessed from 25 each of these places in the eight zones of Bengaluru city. The study areas were chosen by convenience sampling method, and using a questionnaire, the violations were recorded. Data were analyzed in Microsoft Excel to find out the percentage of violations. Results: The COTPA Sections 4 and 5 violation was 134 (67%) and 94 (47%), respectively. A total of 124 (62%) of the educational institutions had tobacco vendors within 100 yards, and only 30 (15%) had signboard for the prohibition of tobacco use. Around 14 tobacco vendors had beedis without proper pictorial warning with them which violated Section 7 of COTPA. Conclusion: For proper implementation of COTPA laws, we should create awareness about the laws, what amounts to violations and also the health hazards to tobacco use among general population. The law enforcing personnel should act on those who violate the law. There is a need for a sensitization workshop and advocacy for all the stakeholders.

Background: There is a paucity of prospective data for patients who progressed after first-line tyrosine kinase inhibitor (TKI) or pemetrexed doublet among epidermal growth factor receptor (EGFR) mutation-positive metastatic non-small cell lung cancer (NSCLC). Aim: The aim of the study was to evaluate the outcome of second-line therapy in patients who progressed on TKI or pemetrexed doublet in EGFR mutation-positive NSCLC. Objective: The objective of the study was to calculate response rates, progression-free survival (PFS), and overall survival (OS) of patients receiving second-line therapy in EGFR mutation NSCLC. Materials and Methods: Post hoc analysis of second-line therapy among patients enrolled in randomized control trial comparing TKI versus pemetrexed doublet in EGFR mutation NSCLC. Kaplan–Meir statistics were used for PFS and OS. Impact of variables was measured with Log-rank test. Results: One hundred and eighty-seven patients who progressed on first-line therapy and received second-line agents were analyzed. Male:female: 110 (56.3%):77 (41.2%). One hundred and thirteen patients received gefitinib, while 74 received chemotherapy. Response rate (complete response + partial response) was 53% versus 24% in gefitinib versus chemotherapy group (RECIST v1.1). PFS was 7.4 months versus 4.4 months (P = 0.001), while OS was 14 months versus 9.7 months (P = 0.007), in gefitinib versus chemotherapy group, respectively. Response to TKI significantly improves PFS (10.8 months vs. 3.9 months, P = 0.001) and OS (21.4 months vs. 8.9 months, P = 0.03). Rash, pruritus, dry skin, fatigue, diarrhea, and paronychia were common toxicities of TKI. Conclusion: Second-line TKI improves outcome in EGFR mutation-positive NSCLC who progressed after first-line chemotherapy. Response to therapy, whether with TKI or chemotherapy, favorably impacts outcomes.

Authors: Muthusamy Rajeshwari K , Mehta Sangita S
Published: November 2018

Neuroendocrine carcinoma (NEC) of the uterine cervix is an uncommon aggressive tumor, comprises <5% of the cervical malignancies. Undifferentiated carcinoma of the cervix, described by the World Health Organization Classification of Tumors as a distinct entity, is extremely rare with no histologic evidence of differentiation. Immunohistochemistry with p63 and neuroendocrine markers helps in delineating the type as undifferentiated squamous cell carcinoma or NEC. NEC of the uterine cervix behaves biologically like any other cervical malignancy, has an association with human papillomavirus, and is similar to NEC of any possible site with early metastasis and poorer survival. We present a case of 45-year-old premenopausal female with undifferentiated carcinoma of the uterine cervix originating from small-cell NEC proven by the presence of differentiated component in the proximity of undifferentiated tumor and by the immunohistochemistry.
Lower Intestinal Langerhans Cell Histiocytosis Masquerading as Chronic Malabsorption Syndrome and Failure to Thrive in a Child: A Rare Case Presented with a Succinct Review of Recent Literature
Authors: Suryawanshi Mayur Keshav , Vig Tanush , Masih Dipti , Joseph Reny
Published: November 2018

Langerhans cell histiocytosis (LCH) encompasses a group of disorders characterized by neoplastic proliferation of Langerhans cells causing destruction of tissue, morbidity and mortality. The authors bring forth the case of a 2-year-old child presenting with chronic diarrhea and features of chronic malabsorption that revealed lesions over the ileocolonic mucosa. Histopathological examination with immunohistochemical expression for CD1a confirmed the diagnosis of LCH. Gastrointestinal LCH is quite uncommon, and review of the published English literature revealed about 50 reported cases. The importance of diagnosing this disease is echoed by the grim survival rate of 18 months from the time of diagnosis that is seen in around 60% of cases. Owing to its rarity and unfamiliarity of practicing physicians and pathologists of this disease at this site, the authors wish to discuss the potential pitfalls and differential diagnoses.
