NEW METAL-CONTAINING POLY(URETHANE-SEMICARBAZIDES) ON THE BASIS OF PYRIDINE DERIVATIVES
Authors: Kositsyna Olena
Published: November 2019

The growth of science and technology of polyurethanes leads to the development of new materials with more desirable properties. Modiﬁcation of polyurethane (PU) by incorporating metal and functional groups are used extensively to improve various properties, such as enhanced thermal stability, ﬁre retardancy, ﬂexibility and solubility. In this investigation, a new metal-containing poly(urethane-semicarbazides) bearing a pyridine moiety have been synthesized and characterized by Fourier transform infrared spectroscopy (FTIR), differential thermal analysis (DTA/TG) and tensile strength measurements. The results showed that the incorporation of metal ions into the polymer chain greatly inﬂuenced their mechanical and thermal properties. The tensile strength measurements on the PU ﬁlms showed a marked difference in the elongation and tensile strength for compositions with various metal salts. The nature of the anion of the salt also affects the properties of the polymers, since the anions are able to form complexes with hydrogen atoms of urethane-semicarbazide PU segments. According to the results of DTA, introduction of metal ions leads to the increase of the thermal stability of metal-containing PU, as compared to the original PU. FTIR spectra data confirmed that the metal ions Cu2+, Co2+ are coordinated in the polymer metal chelates with hydrazide and urethane groups. The research results can be used to develop the new materials and methods for the preparation and designing of metal-containing polymers required in various areas, such as development of medical equipment, functional films and other related areas.

Authors: Lubos Cernaj , Jozef Kozarik
Published: November 2019

The aim of this research is to research and verify possibilities of using the accelerometer to determine mechanical load acting on high voltage insulator. Accelerometer measurements were done on the outdoor post insulator C30 - 850 - II. The insulator was loaded multiple times with various bending force. Vibration induced by external forces was detected by an accelerometer. The insulator features a cable hole, which can be used for optical cables. The accelerometer was glued to the outside surface of insulator’s plate. The results of this research will be used to verify the suitability of the chosen method for detecting the mechanical overload of high-voltage insulators. The results will be used in the design of a device that will serve to detect overload early in order to prevent damage to high-voltage lines and increase its reliability and durability.

Authors: Kozhushko Andrii , Riezva Kseniia
Published: November 2019

The problem of providing functional stability while moving vehicles arises during research of the types of transport works used in agriculture. A wheeled tractor with trailer or semitrailer units is used as a vehicle in the agricultural sector. These days most manufacturers of tractor technology increase the performance of transport work, such as increasing of engines power and cargo transportation. This trend is dangerous, especially when transporting units with variable mass (tanks), because the transportation of liquid cargo leads to significant self-oscillations, which effects on the movement dynamics. One of the studies that characterizes the dynamics of the vehicle movement is running smoothness. This research can provide information about the driver's comfort and vibration occurrence in a vehicle. The materials in this article are basic in the study of running smoothness of a tractor with a variable mass unit and also provide prerequisites for the coverage of the recommendations for reducing driver seat and tractor frame vertical acceleration.

Published: November 2019

The article substantiates the necessity to develop methods of computer simulation of neural networks in the spreadsheet environment. The systematic review of their application to simulating artificial neural networks is performed. The authors distinguish basic approaches to solving the problem of network computer simulation training in the spreadsheet environment, joint application of spreadsheets and tools of neural network simulation, application of third-party add-ins to spreadsheets, development of macros using the embedded languages of spreadsheets; use of standard spreadsheet add-ins for non-linear optimization, creation of neural networks in the spreadsheet environment without add-ins and macros. It is shown that to acquire neural simulation competences in the spreadsheet environment, one should master the models based on the historical and genetic approach. The article considers ways of building neural network models in cloud-based spreadsheets, Google Sheets. The model is based on the problem of classifying multidimensional data provided in “The Use of Multiple Measurements in Taxonomic Problems” by R. A. Fisher. Edgar Anderson’s role in collecting and preparing the data in the 1920s–1930s is discussed as well as some peculiarities of data selection.
CHEMICAL MEASUREMENTS BY ELECTRICAL PARAMETERS TO CONTROL THE COMPOSITION OF MULTICOMPONENT LIQUIDS
Authors: Parashchuk Lidiya , Mikhalieva Maryna
Published: November 2019

The authors substantiated the relevance of scientific studies of the electrical properties of multicomponent liquids. Such liquids are real objects that require stock control during operation. This applies to many areas of human activity: environmental monitoring, the chemical and food industries, medicine, and the like. Laboratory methods are unable to meet the following requirements. The electrical properties of substances, including liquids, have been well studied by scientists. In addition, the high level of modern experimental technology allows to combine theoretical and practical achievements, in this case chemical and physical-electrical sciences. In the theoretical provisions regarding the electrical methods for the study of the composition of liquids, the authors, based on the classical knowledge of dielectric conductivity physics, argue for their use for applied chemical measurements. After all, physico-chemical electrical measurements have long been used for the study of two-component standard solutions. The authors propose to improve such measurements and use them for multicomponent liquids. At the same time, it is proposed to use the developed primary converters and a new informative parameter - complex conductivity components (admittance). On the basis of the obtained experimental results, the research conditions are formulated. The measuring system consists of a primary capacitive transducer (carbon electrodes in vessels with the test liquid); multi-frequency current generator (RLC meter) and computer. The dependences of the values of the complex components of conductivity on the frequency of the electromagnetic field between the electrodes for liquids with dissolved substances of different chemical nature and concentrations were investigated. Some individual properties have been established for such substances, which allow to develop methods and methods of operational control of the composition of multicomponent liquids by electrical parameters. The article discusses the scientific and practical results of research and the advantages of the developed methods and methods of composition control for real liquids. Also, some of the scientific facts obtained allow to further develop and develop methods of electro-chemical research with a wider range of constituents, for low concentrations and without complex laboratory manipulations.

Authors: Andrieieva Svitlana , Khaustova Tetyana
Published: November 2019

The aim of research is studying the rheological properties of gelatinized starch dispersions based on physical modification starches, depending on technological factors. Realization of the research aim will allow to obtain products (sauces, filler creams for confectionery products, etc.) using physical modification starches that are capable of selling products with specified structural and mechanical indicators, quality and safety indicators. And also ensure the rational use of raw materials, reduce the complexity of the technological process of production of culinary products. The current trends in the development of starch technology for physical modification and their use in food technology are analyzed. A review of literature data has become the background for the use of these starches in food technology, which primarily draws attention to the colloidal stability of food systems. A decrease in viscosity (the tendency ηmax=>ηmin) indicates the destruction degree of structural elements under the influence of mechanical stress and thermolysis. Tapioca starches “Endura”, “Indulge” and waxy maize starch “Prima” have practically the same values η (min) and η (max), which indicates the stability of the structure of gelatinized starch dispersions. This is probably due to the fact that grains with a monodisperse fraction (≈83 %) swell and gelatinize equivalently. A study of the effect of acids on the formation and stability of gelatinized starch dispersions shows that the most pronounced stability is characterized by dispersions based on Prima waxy starch and Endura tapioca. The gelatinized starch dispersions based on corn starch amylopectin exhibit low stability during the maximum peak gelatinization depending on the effect of sugar and acid. A thermodynamic study of physical modification starches wi carried out, which confirms the amount of energy expended on unpacking the starch grain, which confirms the initial gelatinization of starches.

Published: November 2019

Calculations of building structures, the development and improvement of calculation methods, the use of numerical methods in solving these problems are one of the promising areas. The paper presents on the basis of the theory of plastic flow with hardening the equations of state in increments, the equations of virtual work, the geometric equations in increments for small elongations, shifts, and rotation angles. The calculations take into account, depending on the intensity of the current load, the elastoplastic properties of the material, both the structure and the soil environment interacting with it, with a complex process of loading [1-3]. For numerical implementation, the equations arising from the conditions of Genius – applicable to concrete, Coulomb - Mohr – applicable to soil environments are applicable. The information presented is implemented in the form of software systems that make it possible to obtain numerical results of solutions to problems in the calculation of underground structures. An example of calculating a structure based on these methods using a software package is also given. The elastoplastic properties of the material, both the structure and the soil medium interacting with it, are taken into account during the complex process of their loading.

Published: November 2019

The purpose of study is to examine the factors behind the purchase intention for counterfeit luxury goods in Bangladesh using the Theory of Planned Behavior (TPB). This research also sought to measure the effect of product attribute, brand image, level of income, price, and gender regarding the purchase intention for counterfeit luxury goods. Data were gathered from a sample of 242 individual respondents living in different areas of Dhaka city who had experience of purchasing various counterfeit luxury goods. A structured questionnaire was used to obtain survey data through a personal interview. Descriptive statistics, reliability statistics, one-way ANOVA, and multiple regression analysis have been used to analyze the collected data. The results show that among five factors, only three of them, such as product attribute, brand images and level of income, are more influential predictors in purchase intention for counterfeit luxury items than price and gender. The findings of the study show a better understanding based on a developing country on how these factors affect purchasing intention of counterfeit luxury items. Thus, the study intends to identify different socio-demographic and behavioral predictors in terms of counterfeiting luxury goods. The result depicts that comparing to original products, Bangladeshi consumers are more prone to use counterfeit luxury items to maintain social values and status. Finally, limitations and managerial implications of the study, along with future research avenues, have been discussed.
Geopolítica, State-Making e industrialização no Brasil o papel do poder militar e do planejamento estratégico no auge do nacional-desenvolvimentismo brasileiro
Authors: Zortea Vieira Ricardo
Published: November 2019

O objetivo do trabalho é contribuir para o debate sobre as causas da experiência brasileira de evolução institucional e desenvolvimento econômico durante a “Era Desenvolvimentista”. O argumento é o de que a geopolítica regional e o poder militar, fatores ignorados nas análises convencionais, tiveram um impacto significativo sobre a estruturação das instituições estatais (State-making) e políticas de desenvolvimento brasileiras em um momento chave do desenvolvimentismo, o Plano de Metas. Para demonstrar essa hipótese, será reconstituída uma tradição de pensamento e ação militar enraizada na geopolítica da Bacia do Prata que ligava defesa nacional com a modernização econômica e centralização política. A evolução dessa tradição estratégica conformou, a partir dos anos 1930 e 1940, um sistema de planejamento que articulava doutrinas e hipóteses de guerra com requerimentos militares e projetos na área econômica. Como demonstração do funcionamento e impacto desse sistema, e, portanto, da variável geopolítica sobre o desenvolvimentismo brasileiro, será mapeada a sua atuação em projetos do Plano de Metas nos setores petroquímico, nuclear, de construção naval e transportes terrestres, além de iniciativas para obtenção de financiamento externo. Conclui-se que além dos fatores apontados pela literatura convencional a geopolítica regional deve ser incluída como uma das causas do desenvolvimentismo brasileiro.

Published: November 2019

English department students of IAIN Pekalongan have many shortcomings in memorizing vocabulary. This is evidenced by our observations when students are speaking in front of the class. Sometimes, students are confused about conveying information they want to deliver because they are constrained by a lack of memorization of vocabulary. The situation happens when students must use English in active discussions. So far, the students tend to memorize vocabulary. Besides that, vocabulary books are less effective and less interesting because it only relies on the use of language skills. One way to learn vocabulary in a simple way is through codenames game. This game provides many vocabularies that must be guessed by the players in a team. Then, another player should describe the word to be guessed. So, this research’s questions are how the codenames game is implemented due to learning English in a fun way. By reflecting the question, the purpose of this research is to provide information on the implementation of codenames game which helps English department students of IAIN Pekalongan enrich and build their vocabulary through a fun way using game cards. Based on our observation, the result showed that applying the codenames game could enrich the students’ vocabularies, be an alternative entertainer so that the students do not easily get bored, and strengthen the students’ memory. Thus, it can be concluded that playing codenames game promotes a helping way to enrich and build the students’ vocabulary.

Perform or wither: role of water users' associations in municipalities of Nepal
Authors: Singh Sreoshi , Shrestha Krity , Hamal Menaka , Prakash Anjal
Published: November 2019

In Nepal, water institutions have played a very significant role, and in Tansen and Damauli, the presence of user groups has indicated that proper management of water can help people avert critical water shortages. However, although in both Tansen and Damauli the user groups have been operating for a long time, their performances vary. In Tansen, infrastructural constraints tend to throw up challenges, although operational hazards associated with the supply systems are no less threatening. Moreover, there is large-scale corruption in the systems' upkeep and maintenance, allowing low grade vendors to operate in place of readily available efficient institutions. In Damauli, the systems have been rather perfectly managed, except for minor glitches from time to time. Funding has been good and community bonding has paid off. This paper delves into the community-managed water systems in the two cities and how the performance varies across them and the factors that play a role.
Measuring Vasculitis with Numbers: Outcome Scores
Authors: Batu Ezgi Deniz , Ozen Seza
Published: November 2019

:

Primary Systemic Vasculitides (PSV) are a heterogeneous group of diseases. Outcome
scores are important to evaluate vasculitis patients in a more structured and standard way and these
help physicians to predict patients with poor prognosis or high risk of relapse. Furthermore, we
need reliable outcome measures for clinical trials. There are a number of vasculitis outcome scores
available in the clinical practice with different strengths and limitations. These are mainly measures
of disease activity, disease damage, response to treatment and quality of life. Birmingham Vasculitis
Activity Score (BVAS) and its pediatric version aim to evaluate a wide scope of PSV. On the
other hand, some outcome studies have focused on a single vasculitis type since the whole group
includes different diseases with heterogeneous clinical features.

:

The aim of this review is to provide an overview on outcome measures currently being used in the
evaluation of patients with PSV. We mainly focus on immunoglobulin A vasculitis/Henochschönlein
purpura, Kawasaki disease, anti-neutrophil cytoplasmic antibody (ANCA)-associated
vasculitis, polyarteritis nodosa, Takayasu arteritis and Behçet’s disease.

Published: November 2019

The selection and supply of electric locomotives based on the life cycle contract requires a more thorough review of indicators of their effectiveness implemented in operation. This study examines the main operation indicators currently used: coefficients of operational availability, technical availability, intrinsic availability (instantaneous), availability of the locomotive fleet, performed ton-kilometer operation, and electric power consumption. However, these indicators are not comprehensive and do not provide an overall economic assessment of operation. For a comprehensive assessment of the effectiveness of operation of locomotives, an online calculation of the life cycle cost is proposed. This involves directly using operating and service data for its performance, and the calculation of an indicator — life cycle specific cost (LCSC). The online LCSC is a uniform criterion associated with the energy efficiency of the performed transportation, volume of the ton-kilometer operation, operation expenses, reliability of electric locomotive, and its equipment availability ratio (EAR). The LCSC analysis enables assessment of deviations of the operation effectiveness indicators from those planned, and determining a strategy for improvement of the electric locomotive. It helps to define peculiarities in the operation of an electric locomotive and to forecast its condition and potential properties. Additionally, the LCSC facilitates analyzing the condition of a group of electric locomotives when changing the operation technology (for example, operation starting with increased rolling stock weight), including assessment of the extent of economic benefits of fulfilled measures.

Currently, scientists of the JSC “VNIIZhT” and specialists of LLC “Ural Locomotives” are conducting tests on the electric locomotives 2EC6 on the Oktyabrskaya railroad using the “Online LCC” server. This allows online analysis of information collected on the operation and servicing of locomotives under the life cycle contract, pro viding effective and prompt control of the electric locomotive fleet.
Automated analysis technology for the transport superstructure heat transfer coeffi cient using a remote server
Authors: Golubin A. A. , Nabatchikova T. I. , Naumenko S. N.
Published: November 2019

The main parameter determined in heat engineering tests of heat insulated cars superstructures or the locomotive operator’s cabs is the heat transfer coeffi cient К. The study introduces automated analysis technology for the heat transfer coeffi cient К of enclosure structures of the heat insulated transport means using a remote server. The underlying method provides coeffi cient K of the heat insulated transport means without additional work and time loss for complicated calculations. Personnel of test laboratories involved in heat engineering tests of vehicles possess tools for remotely calculating К, from any point in the world with internet access. To obtain К three controlled parameters measured during the heat engineering tests for 5.5 h including: the difference of the inside and outside temperature of the test object superstructure, total power of the electric heaters and geometric area of the heat transfer surface are sent to the server, after which the user promptly receives the calculated К. The economic effect of introducing the proposed technology for vehicle manufacture is the absence of required tests conducted at the test center; for an operating company — a signifi cant reduction of the idle time of the vehicle at the test center directly affects the loss of profi t. The proposed technology expands the area of operation of the test centers, while calculated К values are offi cially input into the data sheet of the vehicle.

Authors: Wood (PhD) Van R. , Franzak (PhD) Frank , Pitta (PhD) Dennis A.
Published: November 2019

Economic development requires a complex mix of markets, financial resources, and expertise. Business development in Latin America has followed a tradition of natural resource exploitation, representing a classic example of the “old economy” in today’s global marketplace. However, in order to reap significant economic and social advancements it is imperative that this emerging region embrace a value-added approach requiring increasing knowledge resources. Today, the traditional drives of wealth creation—land, labor and capital—tend to be commodities. Ideas are the now the main currency driving development. One area where ideas flourish is entrepreneurship embedded in small and medium sized enterprises (SMEs). It is here where great promise for introducing innovation and boosting competitiveness lies. This paper, based on these notions, presents a development model that integrate—1) expertise from government agencies charged with enhancing international trade and investment (AITIs), 2) public institutions of higher education (PIHEs) charged with educating the next generation of globally competitive business leaders and 3) small to medium sized enterprises (SMEs) seeking real growth in the globalized business environment leading to a “win-win” situation for all. More specifically, the authors introduce one such model—VITAL (Vibrant International Trade Alliances), and—1) overview the realities of globalization that have created unprecedented SME opportunities for emerging markets, such as those in Latin America, 2) review the importance of entrepreneurship in moving SMEs to the next level of wealth creation, 3) present an example of the model currently utilized in a globally engaged U.S state (Virginia) that has fostered SME and entrepreneurial enterprises in global markets, 4) explains how the model can apply to Latin American nations and also to partnerships between Latin American nations and their U.S. counterparts, and 5) provides managerial, policy and future research implications related to this “boundary spanning” way of thinking.
On-line wear detection of milling tools using a displacement fiber optic sensor
Authors: Castillo-Castañeda E.
Published: November 2019

A cost-effective technique for on-line wear monitoring of a milling tool is presented. The tool wear is estimated directly from a fiber optic sensor with high resolution and high bandwidth characteristics. This sensor provides a distance measurement between its probe and the tool profile. The contribution of this work is the application of this sensor to sense on-line wear of a milling tool. Since the light emitted by this sensor comes from a photodiode, it does not produce eye damage, this is safer than laser displacement sensors. This technique senses the tool wear in real time, while the tool is rotating, with an accuracy less than 1 micron. Experimental results are also presented for a four-flank cutting tool rotating at 300 rpm.

Asynchronous measurement of CDV in ATM networks using OAM cells
Authors: GARCÍA-HERNÁNDEZ J. , GHANBARI M.
Published: November 2019

The synchronisation between source and destination clocks at network nodes to a common reference time of day is important in order to achieve accurate measurements of cells delays in ATM networks. Otherwise, direct measurement of the cell transfer delay and cell delay variation using time-stamped OAM cells would be inaccurate. In this work, a method for the accurate measurement of cell delay variation using OAM cells, which does not rely on synchronised clocks at the measurement points is presented. This is achieved by assuming that each ATM switch has the capability to process and to modify the information contained in the OAM cells. The system presented here was modelled by means of a block-oriented network simulator (BONeS), which is a graphically-oriented, general-purpose simulation language for modelling and simulating communications networks, including ATM networks. The measurements of the cell delay variation were carried out on a VBR video source generated by a real MPEG-2 encoder with a fixed quantizer step size. The simulation results obtained show that measurements of the cumulative cell delay variation carried out without synchronised clocks at the measurement points were very closed to those obtained using synchronised clocks at the measurement points.

Published: November 2019

One of the main points in the development of Educational Software is how to trap, and keep, student's attention. This is a major problem because, unlike the classroom where students are supervised and controlled by teachers, on their computers, at home, they are free to use the software or simply close it and do anything else. The common solution to this problem has been the development of very showy materials, where students are presented to sounds, animations, and sophisticated interactions. Nevertheless, at the Centre of Applied Science and Technological Development we think that this approach might belie some important problems and that other factor must be reviewed and taken into account in order to create good-quality educational software. In this paper we introduce an approach that is based on a study of students, and the identification complete of their beliefs about physics. These beliefs are then used in the development of our software. We present the obtained results; as well as future works perspectives.

Authors: Valera B. , Nava R. , Miranda E.
Published: November 2019

At present, warehouse construction industry makes large vertical stores over small areas causing vertical designs of vehicles and structures. In this situation, the floor must have constant levelness and high flatness in order to achieve the nominal performance of the very narrow aisle lift trucks. With this in mind, in this paper we present a novel system for levelness and flatness measurement based on big surfaces shape measurement. The system has linear and angular optical measurement devices on a mobile robot with automatic drive based on an embedded microcontroller. Readings from the robot are sent to a host computer by means of a radio frequency link for future analysis of level and flatness in agreement with the E1155-87 ASM standard. In addition, this work presents a PC program that receives data from the robot and then sends the data dynamically to a spreadsheet. The complete travel of the vehicle over the measurement area can be made with high degree of automation, reporting remarkable advantages compared to those of a manual process.

A study had been carried out from May 2017 to February 2018 at Suaq Balimbing Research Center, Gunung Leuser National Park to determine the biology of termite nests of Nasutitermitinae subfamily. The termites were collected with Finding Colony method, while the identification of the termite types and data analysis was conducted in Zoology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Syiah Kuala University. The results found 3 types of termite nests, i.e., (1) arboreal mounds type (N. roboratus, N. matangensis, H. bicolor and N. neoparvus) as an attempt to disguise themselves and protect their colonies from predators; (2) wood nesting type (N. havilandi, N. proatripennis, H. hospitalis, B. neopusillus, L. leucops, and Aciculitermes sp.1) that is built using drywood to form ventilation space between nests, so the nests become sturdier; and (3) subterraneannest type (L. longipes) that has a stronger construction than arborealmounds and wood nesting since it is made of soil attached by saliva liquid. Shapes of termite nest found namely a rounded shape, a cone shape, a shape that fills in hollow trees, a shape that forms a mound on the ground, and rectangular shape. Some of the termites activities were searching for food outside the nest, consuming remaining food in the nest, and making an attack. The identification results showed that there were 18 termites species from 6 genera of Nasutitermitinae subfamily namely Nasutitermes, Hospitalitermes, Leucopitermes, Longipeditermes, Bulbitermes and Aciculitermes.

This study aims to determine student learning outcomes and student responses to PQ4R learning strategies in evolutionary studies. To find out the obstacles that might be found. This research is a class action research design. These results are based on the opinions of Thomas and Robinson; the PQ4R strategy is used to help students understand the contents of the reading and remember the material they have read. The results of this study indicate that the learning process of students in evolutionary material in biology learning with PQ4R learning strategies can complete their learning outcomes and increase the level of student mastery. From the overall learning outcomes for two cycles, the student learning outcomes in evolutionary material by applying the PQ4R learning strategy can improve learning outcomes with completeness percentage of cycle I is 78.57% and cycle II is 85.71%, the element of student interest in cycle I is 45.8% and cycle II 51.8%. The improvement of students 'abilities in evolutionary material through PQ4R learning strategies shows that there is an increase in students' learning motivation through diligence in doing assignments, showing interest in learning, pleasure in working individually and in groups, being able to maintain opinions and looking for and solving questions in evolutionary material.

This study aims to determine the character values in laboratory activities, the process of character building and to find out the causes of the reduced character values of biology education students. The method used is the triangulation method. Data collection is done by observation, in-depth interviews and distributing questionnaire sheets. The results showed the lowest character value criteria was honesty, that wasin enough category with an average score of 3.32. It can be concluded that the overall character values of biology education students are classified as good with an average value of 3.55. Although the process of character building for biology education students through laboratory activities has been carried out by providing punishment and rewards, there are reduced character values due to insufficient face-to-face time in laboratory activities, lack of cooperation among assistants, and students’ lack of awareness to obey the rules, self-introspection and motivation.
