Published: April 2019

Liquified Natural Gas (LNG) has become a basic energy source which is mainly used to run industrial wheel. It has played a vital role for boosting economic growth/GDP of Pakistan. Most of power plants and industries use LNG for generation of commodities of domestic use. The contribution of LNG in the total energy supply is 38% which increases up to 40% in winter. This research was conducted in Rana Town Ferozwala. We selected this area because of non-availability of Sui Northern or Southern network of gas pipelines. We used spatial interpolation technique to map the sale of LNG at various sale points throughout the year 2017. We observed the maximum sale of LNG during winter season (Nov-April) where the LNG demands exceeded from 13.2 tons as compared to the normal 8 tons. It was observed that the LNG demand was declined below the approximated demand e.g., a very less amount of LNG was consumed during June and July which was (2.7-6.9) tons and (2.9-6.7) tons respectively that must be more than 8 tons. On field observation we found that most of people prefer the usage of biofuel instead of LNG in summer season because there is excess of dry residue of animals and the dry wood as well for cooking. This trend analysis determines the LNG consumption across a region where interpolation technique proved efficient in public trend mapping for purchase of LNG during 2017.

Authors: Shawon A. K. M. Ashiquzzaman , Ur Soon-Chul
Published: April 2019

Aluminum antimonide is a semiconductor of the Group III-V order. With a wide indirect band gap, AlSb is one of the least discovered of this family of semiconductors. Bulk synthesis of AlSb has been reported on numerous occasions, but obtaining a single phase has always proven to be extremely difficult. This work reports a simple method for the synthesis of single-phase AlSb. Subsequently, consolidation was done into a near single-phase highly dense semiconductor in a form usable for thermoelectric applications. Further, the thermoelectric properties of this system are accounted for the first time. In addition, the mechanical properties of the intermetallic compound are briefly discussed for a possibility of further use.

Authors: Kittisopikul Mark , Virtanen Laura , Taimen Pekka , Goldman Robert D.
Published: April 2019

The nuclear lamina consists of a dense fibrous meshwork of nuclear lamins, Type V intermediate filaments, and is ~14 nm thick according to recent cryo-electron tomography studies. Recent advances in light microscopy have extended the resolution to a scale allowing for the fine structure of the lamina to be imaged in the context of the whole nucleus. We review quantitative approaches to analyze the imaging data of the nuclear lamina as acquired by structured illumination microscopy (SIM) and single molecule localization microscopy (SMLM), as well as the requisite cell preparation techniques. In particular, we discuss the application of steerable filters and graph-based methods to segment the structure of the four mammalian lamin isoforms (A, C, B1, and B2) and extract quantitative information.

Authors: Lin Yu-Hsien , Chen Shao-Yu , Tsou Chia-Hung
Published: April 2019

This study investigated the development of visual recognition and stereoscopic imaging technology, applying them to the construction of an image processing system for autonomous underwater vehicles (AUVs). For the proposed visual recognition technology, a Hough transform was combined with an optical flow algorithm to detect the linear features and movement speeds of dynamic images; the proposed stereoscopic imaging technique employed a Harris corner detector to estimate the distance of the target. A physical AUV was constructed with a wide-angle lens camera and a binocular vision device mounted on the bow to provide image input. Subsequently, a simulation environment was established in Simscape Multibody and used to control the post-driver system of the stern, which contained horizontal and vertical rudder planes as well as the propeller. In static testing at National Cheng Kung University, physical targets were placed in a stability water tank; the study compared the analysis results obtained from various brightness and turbidity conditions in out-of-water and underwater environments. Finally, the dynamic testing results were combined with a fuzzy controller to output the real-time responses of the vehicle regarding the angles, rates of the rudder planes, and the propeller revolution speeds at various distances.

Authors: Zhang Meng , Zhang Wu , Wu Zhengwei , Shen Yinan , Chen Yicheng , Lan Chaofeng , Li Fengchen , Cai Weihua
Published: April 2019

Fluid mixing plays an essential role in many microfluidic applications. Here, we compare the mixing in time pulsing flows for both a Newtonian fluid and a viscoelastic fluid at different pulsing frequencies. In general, the mixing degree in the viscoelastic fluid is higher than that in the Newtonian fluid. Particularly, the mixing in Newtonian fluid with time pulsing is decreased when the Reynolds number Re is between 0.002 and 0.01, while it is enhanced when Re is between 0.1 and 0.2 compared with that at a constant flow rate. In the viscoelastic fluid, on the other hand, the time pulsing does not change the mixing degree when the Weissenberg number Wi ≤ 20, while a larger mixing degree is realized at a higher pulsing frequency when Wi = 50.
Dynamic Change Characteristics of Groundwater Affected by Super-Long Tunnel Construction in the Western Mountainous Area of China
Authors: Zhang Zhiqiang , Xu Peng , Zhang Heng , Zhang Kangjian
Published: April 2019

The problem of groundwater is very prominent in super-long tunnel construction, which brings serious potential safety hazards and economic losses to the project. The knowledge of dynamic change characteristics of groundwater and prediction of water inflow is the key to ensure rational design and safe construction in super-long tunnel. In this paper, numerical simulation and in situ observation are conducted to investigate dynamic change characteristics of groundwater and the prediction of water inflow based on the Daxiangling tunnel in Sichuan Province of China. The results show that the numerical model established with detailed geological data and validated with field monitoring data can effectively analyze dynamic change characteristics of groundwater, as well as predict water inflow. The initial state of groundwater is steady when the tunnel is unexcavated. Tunnel excavation has a significant influence on the distribution of groundwater. The flow direction of groundwater will change, and the contour lines of groundwater will be intensive at the tunnel face. These changes will be more obvious and dramatic when the tunnel is excavated into the fault zone, which is a signal that the water inrush is more likely to occur in the fault zone because of a lot of joints and fractures. A connected linear cavity is formed with tunnel holing-through and groundwater begins to flow vertically downwards to the tunnel. As far as the prediction of water inflow is concerned, the numerical method can more precisely calculate the value of water inflow with less than 15 percent relative error compared with the groundwater dynamics method.
Antiviral Therapy for the Next Influenza Pandemic
Authors: Hurt Aeron C.
Published: April 2019

Influenza antivirals will play a critical role in the treatment of outpatients and hospitalised patients in the next pandemic. In the past decade, a number of new influenza antivirals have been licensed for seasonal influenza, which can now be considered for inclusion into antiviral stockpiles held by the World Health Organization (WHO) and individual countries. However, data gaps remain regarding the effectiveness of new and existing antivirals in severely ill patients, and regarding which monotherapy or combinations of antivirals may yield the greatest improvement in outcomes. Regardless of the drug being used, influenza antivirals are most effective when treatment is initiated early in the course of infection, and therefore in a pandemic, effective strategies which enable rapid diagnosis and prompt delivery will yield the greatest benefits.
Hands Ahead in Mind and Motion: Active Inference in Peripersonal Hand Space
Authors: Lohmann Johannes , Belardinelli Anna , Butz Martin V.
Published: April 2019

According to theories of anticipatory behavior control, actions are initiated by predicting their sensory outcomes. From the perspective of event-predictive cognition and active inference, predictive processes activate currently desired events and event boundaries, as well as the expected sensorimotor mappings necessary to realize them, dependent on the involved predicted uncertainties before actual motor control unfolds. Accordingly, we asked whether peripersonal hand space is remapped in an uncertainty anticipating manner while grasping and placing bottles in a virtual reality (VR) setup. To investigate, we combined the crossmodal congruency paradigm with virtual object interactions in two experiments. As expected, an anticipatory crossmodal congruency effect (aCCE) at the future finger position on the bottle was detected. Moreover, a manipulation of the visuo-motor mapping of the participants’ virtual hand while approaching the bottle selectively reduced the aCCE at movement onset. Our results support theories of event-predictive, anticipatory behavior control and active inference, showing that expected uncertainties in movement control indeed influence anticipatory stimulus processing.

Authors: Ornatskyi D. , Kuzmych L. , Kvasnikov V.
Published: April 2019

The simulation of the analog interface circuit based on the measuring amplifier with differential inputs and the ultrasonic scheme and algorithm of non — destructive additive — multiplicative correction have been made. Such schematic of the analog interface reduces the influence of input correlated noise of operational amplifiers and network drives on the «general» resistance.
The Fig. 1 shows us the Schematic of the electrical functional analog interface for remote measurement using multiplexer and resistive strain gauges, which contains a measuring chain, a transmitter, the input of which is connected to a DC source through an analog demultiplexer, and the outputs of the measuring chain through the analog multiplexer are connected to the measuring amplifier, and a two-channel analog-digital converter with simultaneous sampling. The measuring chain is made in the form of three resistive current dividers, where one divider is formed by a resistive strain gauge and adjusting resistor, and two others — exemplary resistors.
At the Fig. 2 we can see the electric model of the measuring channel in the software Elektronic Workbench.
From the analysis of the simulation results it was found that the random additive component of the error would dominate. Since in the simulation of the only random component of the error there is a quantization error, the use of the differential method of measuring the output voltage will significantly improve the metrological characteristics.

The Uncertainty of Measurements as a Tool for Evaluating the Adequacy of the Mathematical Measurement Model
Authors: Korobko A. , Nazarko O.
Published: April 2019

The article offers a new way of estima-ting the influence of random and methodical errors to the result of measurement for the measurement uncertainty index. The ratio of the difference between theo-retical and experimental data is proposed from the average error of their determination for the quantitative indicator of the influence of methodical error. The ratio of the uncertainty in the measurement of experimental data to the uncertainty in measuring theoretical data for a quantitative measure of the effect of a random error is proposed. These indicators are based on the assumption that the theoretical and experimental data are normally distributed. The theoretical distribution va-ries within the total uncertainty of measurement of type B of the parameter under study. The physical essence of the indicator of the influence of the metho-dical error is the probability with which the results of measuring the average value of the indicator (determined experimentally) are within the li-mits of a possible deviation of the theoretical value of this indicator.

Authors: Cherepkov S. , Dulya V. , Maliavskyi V.
Published: April 2019

Since January 01, 2016, new legislation in the field of metrology came in force in Ukraine. There have been significant changes in the regulation of metrological activity in accordance with the new Law of Ukraine “On Metrology and Metrological Activity”, which is harmonized with European legislation, in the country. Thus, the new Law lacks such forms of metrological control as state acceptance tests and state control tests, as well as state metrological certification of measuring instruments. Instead of these types of metrological control the conformity assessment system of measuring instruments according to established requirements has been implemented. Therefore, this article considers new approaches of the conformity assessment system of measuring instruments according to established requirements and is a logical continuation of an article published in Metrology and Instruments journal (1 (69), 2018), which considered the basics of development and operating the conformity assessment system of measuring instruments. This article considers some issues related to conformity assessment procedures. Criteria for the selection of modules for the conformity assessment procedure and their description are defined. The existing approaches for selection of conformity assessment procedures of measuring instruments and the cooperation of manufacturers (suppliers) of measuring instruments with designated conformity assessment bodies on the market are given. The article offers practical interest for manufacturers of measuring instruments for the legal regulated sphere.
Manage the Selectivity of the Analysis
Authors: Kozubovskyy V.
Published: April 2019

In the traditional analyzers of the total concentration of combustible gases (a mixture of concentrations of combustible gases), the dependence of the signal value for each component of the mixture is determined by from their concentrations. This signal should be enclosed in the range from 0.5% LEL to 50% of the LEL. The calibration of this analyzer is carried out on some gas that lies within the this range. Usually methane or propane is used for this purpose [1,2]. In the article the possibility of controlling the selectivity of the analysis of gas components by the methods of negative filtration [3] of the useful signal in the optical path of the gas analyzer is considered. There are many analytical tasks for which it is necessary to achieve the same sensitivity to the measured gas components. For example, in the analyzer mentioned above, the total concentration of combustible gases in the air. Indeed, different combustible gases can lead to similar effects and it is not possible to determine the concentration of each. The most common are flammable gases such as methane, butane, propane. Of course, it is desirable that the combustion gas alarm has the same sensitivity to these gases and does not respond to interfering, such as CO2.

Authors: Hrihorenko I. , Hrihorenko S.
Published: April 2019

The paper considers the solution of the scientific and practical task of developing a system for monitoring environmental parameters in an aquarium from creating a structural diagram and an algorithm to working up to developing a basic electrical circuit. The factors affecting the livelihoods of fish in an aquarium are analyzed, and the main ones that need to be controlled are established. The uncertainty of the measurement results of the established basic parameters of the medium, namely temperature and dissolved oxygen, was calculated, which proved the possibility of ensuring high accuracy and reliability of measurement results obtained using the developed control system. The developed control system allows to ensure the relative measurement error not worse than 0.5%.
The need to develop a control system is connec-ted with the fact that in order to ensure the normal development of fish and plants in the aquarium, it is necessary to create an environment that is as much as possible natural. This requires timely temperature control, as well as control of the pH and dissolved oxy-gen, which is possible only with the help of an automatic control system.
The system allows the sending of SMS commands for switching on/off the heating and aeration of water in the aquarium, receiving reports on the condition of the heater and the aerator (on/off) and the measured environmental parameters. It is possible to program, for example, sending messa-ges with abnormal increase or decrease in temperature or the suspicious rate of its change. In the course of the work the structural and electrical principles of the control system were created, the algorithm of its work was being compiled, the uncertainty of the measurement of the main parameters of the environment in the aquarium was carried out, which proved the possibility of providing high accuracy and reliability of the results of measurements obtained with the help of the developed control system.

Published: April 2019

SE «Ukrmetrteststandart» uses the working standard ВТУ-36 (method of high-temperature vacuum drying) to determine moisture mass fraction in cereals and cereal products. ВТУ-36 components and characteristics are presented. According to results of systematic studies, ВТУ-36 satisfactorily reproduces the certified values of grain moisture content obtained by using standards of a higher level. All-Ukrainian (МПР № 01-05-2006 ФХ) and international (COOMET 379/RU/06 and COOMET 479/RU/09) comparisons in determining moisture mass fraction in cereals and cereal products showed that ВТУ-36 results are equivalent to the results of vacuum-heat units of other participants for whole wheat grains. However, it is not correct to compare the moisture determination results obtained by means of vacuum-heat units with the results of the air-thermal method (ISO 712).

Active Power Measurement Accuracy Increasing by Additional Measurement of Shunt Voltage
Authors: Vdovychenko A. , Tuz J.
Published: April 2019

The broadband transfer power wattmeter with the correction of the own consumption error for measuring the active power against the background of large reactive components in the radio frequency range is considered in article. The objects of research are electromagnetic elements (chokes / transfor­mers), operating at high frequencies and have strongly distorted forms of signals.
When measuring at high frequencies, the channels of the wattmeter become very sensitive to phase errors. It is necessary to minimize links that cause phase shifts. In this connection, it is important to correctly construct the input units of the wattmeter and to make such a transformation, which will provide operations with signal rms valueswithout links phase shifts. The proposed scheme allows this to be achieved, and required gain is carried out without taking into account the phase shift of the signals.
In the basic scheme of the wattmeter(fig. 1), the input device is executed from the main shunt and parallel to the auxiliary distributed shunt connected to it, which is connected to the main resistance of the voltage divider, in which the value of all resistances of the input device is determined by conditions of invariance to the squares of the voltage and load current , and the partially distributed auxiliary shunt is calculated with additional weighting factors to provide the conditions for invariance of the squared of voltage and current and eliminate the error from its own revives.
Features of the construction of the input link of the wattmeter of transfer power with additional measurement of shunt voltage are given in the article(fig.2). Active power with taking into account the influence of the shunt reactive component calculation formulas (7)-(14)is presented.
The basic error of the wattmeter is the error of the low-ohm shunt. It is expedient to use coaxial or triaxial shunts to extend the frequency range. Transfer power wattmeter input link, which contains additional measurement of shunt voltage simulations was performed in the article(fig.3and table 1).
The advantages of such wattmeter are:

possibility to expand the frequency range by taking into account shunt resistance reactive component influence on the measurement final result , which can be achieved not only by hardware (shunt inductance reduction), but also the introduction of the calculated correction after measuring the values of the shunt active and reactive component;
the values of the input device elements can be optimized by the criterion of maximum broadband, since the error from own consumption is taken into account;
in the scheme one low-level shunt is used, which reduces the cost of the wattmeter;
additive errors of the voltage conversion channel are minimized.

Published: April 2019

In article the possibility of definition (assessment) of thickness of a layer (defect) in materials with complex internal structure is considered.It is reached by application of acoustic non-contact control on the basis of the measured value of phase shift between packages of acoustic vibrations which were reflected from «reference» material without layer (defect) and from «interlayer» material with a layer (defect). Control of «reference» materialis shownin fig. 1. As it is possible to see, the coefficient of reflection of a package of acoustic vibrations in this case is defined by a formula (1). Control of «interlayer» material is shown in fig. 2. As it is also possible to see, the coefficient of reflection of a pac­kage of acoustic vibrations in this case is defined by a formula (9). Other value of coefficient of reflection is connected with additi­onal interaction of a package of acoustic vibrations and a layer (defect). As these two coefficients of reflection have different values, between them there is a phase shift determined by a formula (18). Having values of all known parameters of material with complex internal structure, except thickness of a layer (defect), using a formula (18) and other formulas accompanying her, it is possible to define or at least to estimate thickness of a layer (defect).The offered improvement of acoustic non-contact control can be useful also at control of properties of textile materials.

Published: April 2019

Under the conditions of oil price volatility and increasing sanctions pressure, the problem of increasing the efficiency of the government of the Russian Federation becomes more urgent. One of the directions of its solution is to provide state needs with appropriate amounts of resources. For this, it is necessary to solve the task of managing the resource supply of state needs, which consists in a reasonable assessment of the amount of required resources and their delivery to consumers with minimal costs in the required time frame. The paper proposes the use of a dynamic model for solving this problem, which combines the algorithms of production functions, methods for optimizing the capacity utilization, as well as determining the profit generated by the processes being analyzed. The definition of the concept of “state needs” is analyzed, the stages of work of the mechanism for managing resources for state needs in the dynamic supply-consumption cycles of resources are described.
In order to increase the efficiency of managing the provision of state needs with resources, the article proposed the use of the transportation task in conjunction with the EOQ model. The use of inter-sectoral balance has been proposed for determining the volumes of multiplicative effects generated by the processes of resource provision and having both positive and negative effects on these processes. The formation of a management mechanism based on minimizing the discontinuity of rationality, reducing the efficiency of the process of providing state needs with resources, is proposed. The models and methods considered in the article are combined into an algorithm for forming a general model for managing the provision of state needs with resources. The developed general model includes processes of both internal and external dynamics.

This study aimed to investigate English as a Foreign Language (EFL) pre-service teachers’ perceptions towards the use of Computer Assisted Language Learning (CALL) in the English Language Classrooms concerning the teachers’ computer competence and their perceptions of CALL after creating and using their own CALL in language teaching. The participants were EFL pre-service teachers studying in the faculty of education, Mahasarakham University, Thailand. Questionnaires were used to collect the data after teaching with CALL. The findings revealed that the overall computer competence of the participants was a moderate to a high level, yet the participants were not competent in accessing the different types of information and CALL materials online. Furthermore, the participants reported that the use of a computer made language learning interesting and encouraging. However, they demonstrated that a computer training program was required due to the lack of competence in operating some computer programs as well as the inadequate knowledge of new technology for the language learning. It can be surmised that though the EFL pre-service teachers have learned about CALL, they still find the CALL knowledge gained from the teaching methodology courses insufficient for effective CALL integration and design. Therefore, the study suggests that in order to improve teacher preparation courses, the knowledge of CALL including what CALL is, various types of CALL, as well as CALL materials evaluation be provided. Additionally, the understanding of teaching approaches should also be improved along with the technological skills since the knowledge of CALL solely is inadequate to make effective teaching. The teachers need the capability of selecting the right CALL materials and teaching approaches which are appropriate to the lesson.

Métapsychologie des bisexualités adolescentes
Authors: Richard François
Published: April 2019

Cet article examine la façon dont les adolescents utilisent l’oscillation psychique entre masculinité et féminité pour élaborer un œdipe déformé. La bisexualité recouvre, en particulier à l’adolescence, une tendance régressive mortifère vers l’indifférenciation. Elle peut être utilement maniée dans une approche thérapeutique.

Authors: Marchand Jean-Baptiste
Published: April 2019

Aujourd’hui, l’incongruence de genre chez l’adolescent est comme noyée parmi toutes les questions portant sur la dysphorie de genre en général. De même, force est de constater que rares sont les travaux psychanalytiques sur ce sujet. Ainsi, après une succincte présentation de l’actualité sur l’incongruence de genre chez l’adolescent, les aspects psychodynamiques de ce phénomène seront interrogés à travers des extraits de consultations, et des réflexions psychanalytiques sur le genre et l’adolescence.

Menaces sur l’esprit de 1905
Authors: Fourest Caroline
Published: April 2019

Exemples à l’appui, Caroline Fourest tire une nouvelle fois la sonnette d’alarme pour défendre le compromis de 1905, menacé de toutes parts par les instrumentalisations politiques. D’un côté, l’extrême droite y trouve argument pour faire interdire la construction de lieux de culte musulmans en multipliant les recours administratifs douteux. De l’autre, des élus locaux cherchent au contraire à contourner la loi pour financer, par clientélisme, la construction de mosquées, au risque de favoriser l’islam politique au détriment de politiques culturelles et sociales en faveur de l’égalité hommes/femmes et de la laïcité.
Naître citoyen ...et le devenir
Authors: Best Francine
Published: April 2019

La citoyenneté est une question d’éducation, une tâche de formation : sans transmission de savoirs et de valeurs, sans appropriation personnelle par les sujets humains des valeurs liées à la citoyenneté, celle-ci n’est pas envisageable et c’est le moment de rappeler toute la force de la Déclaration Universelle des Droits de l’Homme.
Les associations et l’apprentissage des règles du jeu citoyen
Authors: Colcombet François
Published: April 2019

Par la discussion, le respect de la majorité sans écrasement de la minorité, elles sont souvent d’excellentes écoles d’action collective, des lieux d’apprentissage de la vie dans la cité, de la politique, de la citoyenneté, et finalement d’exercice de la vie démocratique : les associations n’ont pourtant pas toujours eu la vie facile en France.
Les chiffres des migrations et ce qu’ils nous disent
Authors: Wihtol de Wenden Catherine
Published: April 2019

On parle aujourd’hui de circulation migratoire : beaucoup de migrants aspirent à circuler sans nécessairement souhaiter se sédentariser définitivement et beaucoup de pays d’accueil croient pouvoir résoudre ainsi le difficile problème de l’intégration. Le plus grand risque est celui de ne rien faire, car les migrations clandestines interpellent un monde en mouvement, dépourvu de règles communes.
La loi est-elle “l’expression de la volonté générale” ?
Authors: Joxe Pierre
Published: April 2019

La loi est “l’expression de la volonté générale” affirmait la Déclaration des Droits de l’Homme dans la première phrase de son article 6, il y a un peu plus de 200 ans. La deuxième phrase renchérit : “tous les citoyens ont droit de concourir personnellement ou par leurs représentants à sa formation” Or, ce fameux article, célébré depuis si longtemps, est à la fois incompréhensible et dépassé, car il cumule trois tares : ambiguïté, imprécision, contradiction.
Du colonialisme au communautarisme : la République à l’épreuve
Authors: Hadjadj Bachir
Published: April 2019

Les descendants des immigrés sont devenus aujourd’hui français pour la plupart, alors que le regard posé sur eux n’a pas varié, entraînant leur éviction vers les banlieues, et la précarisation de leur situation. Pour ne pas avoir admis que c’est le regard colonial dévalorisant, porté durant des dizaines d’années sur les populations immigrées fragilisées, qui persiste, la société se retrouve dans une impasse, à la merci de tous les pompiers pyromanes.
