Displaying recipiency in doctor-patient conversations
Authors: Fu Liang 
Published: May 2018

AbstractA doctor’s ability to communicate with patients to ensure high-quality health care and the limited spoken materials available to teach this ability in a Chinese for Medical Purpose class call for teaching pedagogies that include authentic doctor-patient conversations to allow the access to the type of language data that properly define language use in medical professional settings. This paper introduces a teaching lesson for a Chinese for Medical Purpose course in which students are provided with a real doctor-patient conversation and guided to explore the doctor’s various ways of displaying recipiency of information from the patient as well as the socio-cultural meanings behind them. Six in-class and out-of-class activities are described in detail which include reflection on English recipient styles, comparison and analysis of Chinese and English spoken data, discussion on the social-cultural meanings and application of the learned recipient styles in oral practice. Issues and recommendations of designing and implementing the lesson plan as well as the outcomes of the lesson are discussed.

Authors: Boavida de Brito Pedro , Moerdijk Ieke 
Published: May 2018

Abstract
We study the covariant model structure on dendroidal spaces, and establish direct relations to the homotopy theory of algebras over a simplicial operad as well as to the homotopy theory of special Γ-spaces. As an important tool in the latter comparison, we present a sharpening of the classical Barratt–Priddy–Quillen theorem.
Electrodeposition of Polymer Nanostructures using Three Diffuse Double Layers: Polymerization beyond the Liquid/Liquid Interfaces
Authors: Divya Velpula , Sangaranarayanan M. V. 
Published: May 2018

AbstractNanostructured conducting polymers have received immense attention during the past few decades on account of their phenomenal usefulness in diverse contexts, while the interface between two immiscible liquids is of great interest in chemical and biological applications. Here we propose a novel Electrode(solid)/Electrolyte(aqueous)/Electrolyte(organic)Interfacial assembly for the synthesis of polymeric nanostructures using a novel concept of three diffuse double layers. There exist remarkable differences between the morphologies of the polymers synthesized using the conventional electrode/electrolyte method and that of the new approach. In contrast to the commonly employed electrodeposition at liquid/liquid interfaces, these polymer modified electrodes can be directly employed in diverse applications such as sensors, supercapacitors etc.

Authors: Tekade Shyam P. , Shende Diwakar Z. , Wasewar Kailas L. 
Published: May 2018

Abstract
The kinetics of the heterogeneous reaction of metal aluminum with water was studied in presence of NaOH as an activator for generating the hydrogen. Aluminum (Al) powder of average size of 100 µm and foil of thickness of 11 µm were utilized to study the effect of the shape of particles of aluminum on hydrogen generation. The hydrogen generation was reported at various concentrations of NaOH, ranging from 0.12 N to 0.67 N. The fractional conversion of Al was found to be 0.66 at 0.12 N and 1.0 at 0.185 N, 0.37 N, 0.54 N, 0.65 N NaOH concentration. The activation energy of the reaction has been determined at the stoichiometric concentration of 0.185 N NaOH at the temperature ranging from 298 to 323 K. An attempt was made to model the reaction using Shrinking Core Model (SCM) for determining the rate controlling mechanism for the heterogeneous reaction. The reaction was observed to follow the first order kinetics and the average value of reaction rate constant using Al power and foil was found to be 27.322 x 10-4 cm/min and 2.125 x 10-4 cm/min respectively.

Published: May 2018

Abstract
The modelling of Lithium-ion batteries is considered as a powerful tool for the introduction and testing of this technology in energy storage applications. In fact, new application domains for the battery technology have recently placed greater emphasis on their energy management, monitoring, and control strategies. Battery models have become an essential tool for the design of battery-powered systems; their usage includes battery state-of-charge (SoC), state-of-health (SoH) estimations, and battery management system design and battery characterization. This paper presents a method on how to estimate Lithium-Ion battery equivalent circuit model (ECM) parameters based on experimental characteristic measurements by charging and discharging the battery at different modes. The experiment is realized with a computer that realizes the control of charge and discharge via LabVIEWTM software. In this paper, tests are conducted on Lithium-Ion battery 18650 (nominal voltage of 3.7 V and nominal capacity of 2900 mAh) with the proposed method to evaluate the battery model parameters. The proposed method has the best dynamic performance and gives accurate parameter identification which enables the use of models to simulate the battery system performance.

Abstract

Background:

Anogeissus leiocarpus is a Sahel tree traditionally used by the residents of Burkina Faso for its antihypertensive properties. In this study, experiments were conducted to evaluate whether an aqueous extract of the Anogeissus leiocarpus (AEAL) trunk bark induces a vasorelaxant effect on porcine coronary artery rings and to investigate the underlying mechanism.

Methods:
AEAL-induced relaxations were assessed using porcine coronary artery rings suspended in organ chambers. The phosphorylation levels of Src, Akt and endothelial nitric oxide synthase (eNOS) were assessed in a primary endothelial cell culture by Western blot. The reactive oxygen species (ROS) formation was assessed using dihydroethidine.

Results:
In porcine coronary artery rings, AEAL at 0.1–300 μg/mL induced endothelium-dependent relaxations, which were inhibited in the presence of inhibitors of nitric oxide (NO) and the endothelium-derived hyperpolarization pathways. Moreover, the AEAL-induced NO-mediated relaxations were significantly reduced by the inhibitors of Src and PI3-kinase as well as by the membrane-permeant ROS scavengers. In cultured porcine coronary artery endothelial cells, treatment with AEAL is associated with an intracellular generation of ROS. Moreover, the AEAL induced the phosphorylations of Akt (Ser473), eNOS (Ser1177) and a transient phosphorylation of Src (Ser17) in a time-dependent manner.

Conclusions:
These findings indicate that AEAL is a potent inducer of endothelium-dependent NO-mediated relaxations in porcine coronary arteries through the redox-sensitive Src/PI3-kinase/Akt pathway-dependent activation of eNOS.
Digital Rights Management System and Administration: A Wake-up Call for Nigeria!
Authors: Ajetunmobi Ridwan Lanre 
Published: May 2018

Abstract
The advent of the digital milieu and the explosion of the internet has made access, use, modification or duplication of original work easy. Physical reproductions have been replaced by digital reproduction, which has become much easier as well as cost-effective. The increased use of digital technology and online activities pose a serious threat to the cardinal objective of copyright protection. To counter these threats, measures have been developed technologically to make digital works difficult to copy, distribute and access without the necessary permission. These measures are covered under the heading of Digital Rights Management (DRM). Traditional copyright laws did not contemplate these threats and does not make provision to tackle them. Several countries have amended their copyright laws to address the threats posed by digital advancement. In this context, Nigeria has a draft (amendment) bill, 2015, which is before its national assembly. This paper calls for the swift passage of the bill to enable Nigeria to effectively provide for a legal framework to counter the threats posed by these digital advancements.
From 3D Scans to Networks: Using Swords to Understand Communities of Central European Bronze Age Smiths
Authors: Golubiewski-Davis Kristina 
Published: May 2018

Abstract
This case study uses 3D scans of Central European Bronze Age swords (~1400-800BC) to recreate community networks of knowledge. 3D scans of 111 bronze swords were analyzed, from which measurements including blade profile, hilt profile, and decorative shape data were collected. The data were analyzed using a variety of statistical methods. Cluster analysis was used to create links between the nodes of networks that were modelled. A community detection algorithm was run on the networks to examine potential communities of bronze smiths based on theorized manufacturing decisions. These analyses suggest there were four distinct areas within which craft workers were sharing knowledge.
Aristotle’s Vocabulary of Pain
Authors: Cheng Wei 
Published: May 2018

AbstractThis paper examines Aristotle’s vocabulary of pain, that is the differences and relations of the concepts of pain expressed by (near-)synonyms in the same semantic field. It investigates what is particularly Aristotelian in the selection of the pain-words in comparison with earlier authors and specifies the special semantic scope of each word-cluster. The result not only aims to pin down the exact way these terms converge with and diverge from each other, but also serves as a basis for further understanding Aristotle’s philosophical conception of pain.

Authors: Şöhret Yasin 
Published: May 2018

Abstract
The aircraft industry, along with other industries, is considered responsible these days regarding environmental issues. Therefore, the performance evaluation of aircraft propulsion systems should be conducted with respect to environmental and ecological considerations. The current paper aims to present the ecological coefficient of performance calculation methodology for aircraft propulsion systems. The ecological coefficient performance is a widely-preferred performance indicator of numerous energy conversion systems. On the basis of thermodynamic laws, the methodology used to determine the ecological coefficient of performance for an aircraft propulsion system is parametrically explained and illustrated in this paper for the first time. For a better understanding, to begin with, the exergy analysis of a turbojet engine is described in detail. Following this, the outputs of the analysis are employed to define the ecological coefficient of performance for a turbojet engine. At the end of the study, the ecological coefficient of performance is evaluated parametrically and discussed depending on selected engine design parameters and performance measures. The author asserts the ecological coefficient of performance to be a beneficial indicator for researchers interested in aircraft propulsion system design and related topics.
Aerodynamic Performance Characteristics of NACA 0010 Cascade with Gurney Flaps
Authors: Nilavarasan T. , Joshi Ganapati. N. , Chandel Sunil 
Published: May 2018

AbstractComputational investigations on the effect of Gurney flaps in a NACA 0010 cascade with a 90oblade angle were carried out using STARCCM+ code. The flaps were positioned at the trailing edge of the blades and were aligned at 45oand 90oto the blade chord. The variations in the lift, drag, aerodynamic efficiency and static pressure distributions were recorded on the blades and were compared with the baseline case. Significant increase in the lift coefficient was observed due to the Gurney flaps accompanied by a small drag penalty. This is achieved by increasing the effective camber of the blade, thereby increasing the pressure difference between the pressure and suction surfaces. The Gurney flaps increased the aerodynamic efficiency of the blade at lower angles of attack, whereas at higher angles a small drop in the value was observed.

Published: May 2018

Abstract
Hair follicles can serve as an effective reservoir for dermal drug delivery upon the topical application of particulate substances. Here, the follicular penetration of an indodicarbocyanine-labelled thermoresponsive nanogel (189 nm) having a cloud point temperature of 34°C and linked via an acid-labile linker to the model drug indocarbocyanine was investigated. In total, 227 hair follicles of porcine ear skin were examined after topical application of the thermoresponsive nanogels at room temperature (21°C), physiological skin surface temperature (32°C) and core body temperature (37°C) for the follicular penetration depths of indodicarbocyanine and indocarbocyanine using confocal laser scanning microscopy. The results showed a significantly increased mean follicular penetration of the carrier to a depth of 298.8±85.8 μm after incubation at 37°C compared to samples incubated at 21°C and 32°C with mean follicular penetration depths of 202.7±81.7 μm and 219.4±52.9 μm, respectively (p<0.001). Possibly structural changes in the thermoresponsive nanogel induced by the increased incubation temperature led to an enhancement of follicular penetration. Therefore, thermoresponsive nanogels may be suitable for the temperature-enhanced penetration into the hair follicles under physiological conditions.
The Microstructure and Water Distribution of Partially Saturated Hard Clay
Authors: Chen Liufeng , Peng Hua , Yang Diansen 
Published: May 2018

Abstract
This article presents an experimental investigation of the microstructure and water distribution of partially saturated natural hard clay. A series of natural hard clay specimens were desaturated using a controlled-suction technique and then examined using nuclear magnetic resonance relaxometry (NMR) and mercury intrusion porosimetry (MIP). NMR allows one to investigate the microstructure and the water distribution of the material, while MIP can provide information about the free space distribution of the material. The results of NMR are consistent with the MIP measurements and show that the pore size of the hard clay has a similar unimodal distribution. The relaxation time distribution curves are closely related to the water content of the specimens. The dehydration mechanism of the hard clay is revealed by both NMR and MIP: the water progressively evaporates from large pores to small pores. The peak of the T2 relaxation time distribution decreases with a decrease in water content, and the peak of the free pore size distribution increases during hydration. The results of NMR and MIP are consistent and reveal the same dehydration mechanisms. The limits of NMR and MIP for partially saturated materials will be discussed in this text.
Guidance for Investigating Calcite Precipitation by Urea Hydrolysis for Geomaterials
Authors: Shashank B. S. , Minto James M. , Singh Devendra Narain , Mountassir Gráinne El , Knapp Charles W. 
Published: May 2018

Abstract
Microbially induced calcite precipitation (MICP) is a sustainable method of stabilizing (i.e., cementing) loose sandy deposits or creating an impervious barrier within the soil mass or both. MICP can occur through various biochemical pathways, and ‘Urea Hydrolysis’ (UH) is considered to be the most efficient of the MICP methods for biochemically inducing calcite precipitation. To date, the geotechnical engineering community that has investigated MICP has tended to focus on the hydromechanical behavior of the end product, i.e., MICP cemented sands; however, many biochemical factors that affect reaction-rate kinetics and MICP outcomes have been understudied or neglected. This study investigates the kinetics of UH and compares different sources of the urease enzyme—those microbially cultivated in the laboratory (i.e., Sporosarcina pasteurii) and those extracted from plants (i.e., Jack bean meal)—to investigate the influence of urea concentration, buffer capacity, and the cell harvesting method on UH. Through this study, an attempt has been made to arrive at an optimal concentration of urea, under the influence of the previously mentioned parameters and the buffering action of the soil, on urea hydrolysis. These results have implications for optimizing MICP and, in particular, for upscaling these methods to in situ applications.
Review of Residual Stress Measurement by Magnetic Barkhausen Noise Technique
Authors: Gur C. Hakan 
Published: May 2018

Abstract
Determination of residual stress state is important for quality, integrity, and service performance of the components and structures. Almost all manufacturing processes cause considerable amounts of residual stress; thus, any process or product design ignoring it involves a risk for distortion or early failure. Among the existing methods, the magnetic Barkhausen noise method has been gaining attention for measuring residual stresses nondestructively in ferromagnetic materials. It is sensitive to the interactions between the magnetic structure and microstructure or residual stress fields. So far, successful qualitative results have been obtained for monitoring the residual stress variations on the surfaces of the components manufactured by various processes. However, some challenging tasks exist, such as obtaining reliable quantitative results when residual stresses and microstructure change at the same time or extracting depth-specific information. This article reviews the studies for the measurement of residual stress by magnetic Barkhausen noise method, particularly focusing on the processes widely used in industry, namely shot peening and welding.
Schaffer Collateral Inputs to CA1 Excitatory and Inhibitory Neurons Follow Different Connectivity Rules
Authors: Kwon Osung , Feng Linqing , Druckmann Shaul , Kim Jinhyun 
Published: May 2018

Neural circuits, governed by a complex interplay between excitatory and inhibitory neurons, are the substrate for information processing, and the organization of synaptic connectivity in neural network is an important determinant of circuit function. Here, we analyzed the fine structure of connectivity in hippocampal CA1 excitatory and inhibitory neurons innervated by Schaffer collaterals (SCs) using mGRASP in male mice. Our previous study revealed spatially structured synaptic connectivity between CA3 and CA1 pyramidal cells (PCs). Surprisingly, parvalbumin-positive interneurons (PVs) showed a significantly more random pattern spatial structure. Notably, application of Peters' rule for synapse prediction by random overlap between axons and dendrites enhanced structured connectivity in PCs, but, by contrast, made the connectivity pattern in PVs more random. In addition, PCs in a deep sublayer of striatum pyramidale appeared more highly structured than PCs in superficial layers, and little or no sublayer specificity was found in PVs. Our results show that CA1 excitatory PCs and inhibitory PVs innervated by the same SC inputs follow different connectivity rules. The different organizations of fine scale structured connectivity in hippocampal excitatory and inhibitory neurons provide important insights into the development and functions of neural networks.SIGNIFICANCE STATEMENTUnderstanding how neural circuits generate behavior is one of the central goals of neuroscience. An important component of this endeavor is the mapping of fine-scale connection patterns that underlie, and help us infer, signal processing in the brain. Here, using our recently developed synapse detection technology (mGRASP and neuTube), we provide detailed profiles of synaptic connectivity in excitatory (CA1 pyramidal) and inhibitory (CA1 parvalbumin-positive) neurons innervated by the same presynaptic inputs (CA3 Schaffer collaterals). Our results reveal that these two types of CA1 neurons follow different connectivity patterns. Our new evidence for differently structured connectivity at a fine scale in hippocampal excitatory and inhibitory neurons provides a better understanding of hippocampal networks and will guide theoretical and experimental studies.
A CLOSE CORRELATION BETWEEN DISORDERS-DEFECTS AND SUPERCONDUCTING TRANSITION TEMPERATURE OF Bi1.6Pb0.4Sr2Ca2-xNaxCu3O10+δ SUPERCONDUCTORS
Authors: Duc Tran Hoai 
Published: May 2018

The enhancements of zero superconducting transition temperature (Tc,0) in Bi1.6Pb0.4Sr2Ca2-xNaxCu3O10+δ(BPSCCO) are reported. The BPSCCO samples (with x ranging from 0.00 to 0.06) were prepared by using the conventional solid state reaction technique. The properties of the samples were examined by using the X-ray diffraction (XRD), scanning electron microscopy (SEM), and the resistance versus temperature (R-T) measurements. From the XRD resuts, all samples revealed the orthorhombic structure, and the volume fraction of the Bi-2223 phase was varied as increasing x, and reached the maximum value of 82.72 % for x = 0.05 sample. Improvements of connectivity between the Bi-2223 grains in the Na-substituted BPSCCO samples were obtained by using the surface SEM images and a quantitive analysis of a correlation between Tc,0 and residual resistance ratio (RRR). A similar variation of Tc,0 of the samples as increasing x was observed. The highest Tc,0 enhancement of 107.5 K was obtained for x = 0.05 sample. Variations of the hole carrier concentrations in the CuO2 layers were investigated, which also showed the highest value achieved for x = 0.05 sample.
