La enfermedad de Parkinson (EP) es una patología neurodegenerativa, progresiva e incurable; con el fin de mejorar la calidad de vida de las personas que la padecen, se propuso el diseño y construcción de un dispositivo mecatrónico que permita el análisis de los movimientos involuntarios producto de la enfermedad. Dicho dispositivo permite, mediante el uso señales electromiográficas producidas por los músculos del antebrazo y de un algoritmo basado en redes neuronales artificiales, el análisis de los movimientos involuntarios de pronosupinación generados en las extremidades superiores. Para la materialización del dispositivo se tomó en cuenta técnicas de prototipado rápido como lo es la impresión 3D y el modelo en V aplicado a la Mecatrónica. Como resultado de este trabajo de investigación se obtuvo un dispositivo mecatrónico en forma de exoesqueleto controlado por un sistema embebido que analiza y procesa señales electromiográficas y, mediante redes neuronales artificiales, permite la clasificación del temblor y de movimientos voluntarios producidos por cada paciente. Los resultados del funcionamiento del sistema son: para la predicción de temblor 96.88 % de acierto y para la predicción de movimiento voluntario 100 % de acierto.
Multi-frequency method of control for eddy current thickness measurement
Authors: Chernyshev A. V. , Zagorskiy I. E. , Sharando V. I. 
Published: March 2019

When eddy-current thickness measurement is carried out, one of the disturbing factors leading to an error in determining the thickness of the conductive coating on a conducting ferromagnetic or non-ferromagnetic substrate are the variations of the electromagnetic parameters of the coating and the substrate observed when the transducer moves from point to point along the surface of the controlled product, when moving from one product to another, at presence of heat treatment or other thermal effects on the controlled product after coating. The paper presents the results of experimental studies of the influence of variations in the electromagnetic parameters of a conducting ferromagnetic substrate on the phase of the emf, introduced into the superimposed transducer. It is shown, when the minimum influence of such variations on the specified phase is achieved. As a result, it was suggested to use the multi-frequency method to reduce the influence of variations of electromagnetic parameters on the accuracy of determining the coating thickness during application of the phase control method. It consists in the fact that the frequency of the excitation current of the transducer, mounted on the monitored product, is discretely reduced from a certain maximum to a certain minimum frequency during measurements. At the high frequency, the specific electric conductivity of the coating material is taken into account, with decreasing frequency, such a value is determined when the electromagnetic parameters of the substrate begin to affect the phase formation. Then, using the calibration curve obtained from samples from the same coating material and substrate as the controlled article and having a known coating thickness, the desired coating thickness on the product to be tested is determined.
Integral method of solving heat-conduction problems with the second-kind boundary condition. 3. Pulsed laser heating
Authors: Kot V. A. 
Published: March 2019

Exact and approximate solutions to the non-stationary problem on the heat conduction in a semi-bounded body exposed to a pulsed laser radiation flow have been obtained. The action of rectangular, triangular and parabolic laser radiation pulses on this body was investigated. Polynomial relations have been constructed on the basis of the boundary-characteristic method with introduction into consideration of the temperature-disturbance front, and they made it possible to obtain practically exact solutions for the temperature function and its time derivative at both the stages of heating and cooling of the body. It is shown by some examples that the success in solving problems on the pulsed plasma heating of bodies is associated in many respects with the necessity of definition of the time law of movement of the temperature-disturbance front with the use of the Pade diagonal approximation, which excludes, practically completely, the divergence of the power series defining the law of movement of this front, in particular, in small time intervals. The approach proposed for solving heat-conduction problems with the second-kind boundary condition allows one to simply and effectively find solutions for isotherms and lines of equal heating and cooling. Analysis of the results obtained allows the conclusion that the effectiveness of solving various technological problems, based on the use of pulsed laser radiation, is determined by the success in solving the problems on control of the time shape of a laser pulse and determination of the temperature fields in the body on the basis of polynomial representations.

Published: March 2019

In the work the technology of radio-frequency identification of objects with inductive coupling is considered, using passive electric oscillating circuits tuned to fixed frequencies from the working frequency range as identification features of the object. The choice of the primary measuring transducer and the informative parameter is based on the results of the analysis of the system of inductively coupled active and passive electric oscillation circuits, known from the theory of radio engineering circuits. The parameters of the measuring transducer ensuring the fulfillment of the requirements for identification and localization of objects specified by technological conditions are substantiated. Factors that are potentially dangerous with respect to reducing the information reliability of the measuring transducer are considered, as well as the possibility of reducing their influence to a minimum. The problems of experimental research are formulated. It is shown that the analysis can be performed by software discrete adjustment of the primary measuring transducer and the generator feeding it. In this case, the task of increasing the speed is targeted at decreasing the duration of the step of tuning the primary measuring transducer. The required reliability of object identification is achieved by: ensuring high stability of the frequencies of the generator supplying the primary measuring transducer; accuracy and stability of tuning of the primary measuring transducer to the frequencies of the supplying generator; protection of the primary measuring transducer from the influence of interference generated by external sources and other measuring converters of the object identification system (electromagnetic compatibility of the object identification system); sufficient magnitude of the response of the primary measuring transducer to the introduction of passive electrical oscillation circuits; sufficient frequency tuning interval for passive electric oscillation circuits; accuracy and stability of tuning of passive electric oscillation circuits; stability of the detection threshold relative to the initial level of the informative parameter. Electromagnetic compatibility of measuring transducers, whose sensing elements are in the zone of mutual influence, is provided by synchronizing the operation of measuring transducers with shunting of inactive sensors, screening, mutual orientation and spacing of sensing elements.

ADMINISTRATIVE SOLUTIONS FOR IMPLEMENTATION OF COMPETITION PROJECTS IN THE FRAMEWORKS OF PUBLIC-PRIVATE PARTNERSHIP
Authors: Шкода Мар’яна Сергіївна 
Published: March 2019

The overall goal of public-private partnership projects (PPPs) is to find solutions to problems combining the benefits of the private sector (availability of financial assets, good governance, propensity for innovation and entrepreneurship) with the advantages of public sector (social issues and environmental concerns). From an economic feasibility perspective, the PPP project should integrate the efficiency of resource allocation with production efficiency which totally outperforms the selected public or private projects. Traditional PPP management (projects under the current stage of national economic development) loses its edge since it stems from the assumption of about the project scale dimension, that is, the project results validity (products to be made and their inherent properties). Thus, eventual PPP projects should be viewed through the prism of systems thinking and management paradigm through which the project becomes apparent not in isolation but as a whole in the context of what is happening. The research findings provide evidence that enhancing management efficiency at all stages of the PPP project can be achieved through implementation of the following actions: 1) improving public access to information about the project and the competition procedures; 2) creating individual websites for the participation of potential partner companies in the competition (for medium and small projects, in particular); 3) increasing competition; 4) building a real project team with an effective leader; 5) providing opportunities for selective monitoring of the performance with the participation of external consultants, thus facilitating a framework for enhancing transparency and overall control as well as contributing to reducing corruption.

Authors: Nduwimana Arcade 
Published: March 2019

This study examines the views that tertiary English teachers hold on the need for English for Specific Purposes (ESP) in Burundi higher education. To do so, it investigates the extent to which they are familiar with the theory and practice of ESP. For this study, 32 English teachers were contacted to participate in it. They were all requested to complete an online questionnaire, but only 17 proved willing to do so. The findings revealed that the majority of teachers are familiar with the practice of ESP. Although many of them reported to have high familiarity with the field of ESP, a few of them conduct a Needs Analysis (NA) before teaching ESP courses. Results also indicated that tertiary English teachers highly acknowledge the importance of teaching ESP in Burundi higher Education and, therefore, would encourage the ministry of education to fund an ESP project.

Over the past few decades, caring for special patients has taken center stage in healthcare systems. Moreover, what necessitates conducting a comparative study into the conditions of special patients and designing a suitable model are as follows: high admission rates of these patients in hospitals, continual recurrence of the illness, sky-high costs of treatment and medicine, lack of coordination between the services offered by hospitals and community needs, and severe pressure of special patients on their families. Therefore, the present study aimed to compare the models of government support programs for special patients in Iran, the United Kingdom, the USA, Italy and Sweden through a descriptive-documentary method. The findings revealed that the Ministry of Health and Welfare and the private sector were the major providers of health services to special patients in most of the countries under study. It was also demonstrated that the services offered to special patients are jointly mainly funded by governments, associations, and non-governmental organizations and partially by insurance premiums and so forth. The results also indicated that the bulk of healthcare provision was shouldered by non-governmental sectors and the contribution of charitable people. Finally, it can be concluded that both health-related policies and the health of special patients can be closely honed and monitored through the formation of committees on the health of special patients at the Supreme Council of Health, the establishment of an office for special patients at the Vice-chancellery for Health at the Ministry of Health, Treatment and Medical Education, provision of decentralized services, and financing through taxation and contribution of charitable people and international organizations.

Published: March 2019

BACKGROUND: Berry skin tissue is important in viticulture and enology due to the storage of phenolic compounds. Changes in the berry metabolism and environmental factors may lead to changes in skin structure and composition. OBJECTIVE: We aimed to determine the effects of kaolin-based particle film (PF) treatment on histological properties of anthocyanin accumulation in the berries of cv. Beauty Seedless and Tekirdag Seedless in two growing seasons. METHODS: PF treatment was applied 3 times beginning from the berry set. Histological structure of berries was observed with optical and transmission electron microscopy. Accumulation of anthocyanins in berry skin cells was determined microscopically and spectrophotometrically. RESULTS: In Beauty Seedless, total anthocyanin content was 512.93–605.90 mgkg–1 in control (C) and it raised to 606.98–666.44 mgkg–1 in PF treated vines. Total anthocyanin content was determined as 72.50–81.43 mgkg–1 (C) and 79.55–84.72 mgkg–1 (PF) in Tekirdag Seedless. 3 cell types were observed regarding anthocyanin localization: cells with no anthocyanin (type 1), cells with vacuolar storage (type 2) and cells with granular storage (type 3). CONCLUSION: We concluded that the PF treatment could be used for increasing anthocyanin concentration with cultivar-specific skin color in Beauty Seedless and Tekirdag Seedless grown in the semi-arid regions.

Published: March 2019

BACKGROUND: Strawberry is one of the most highly consumed fruits worldwide. However, it is highly a perishable fruit postharvest. OBJECTIVE: To assess the effect of dipping strawberry fruits after harvest in plant growth regulators to maintain postharvest quality. METHODS: Treatments tested were: 2 and 4 mM salicylic acid (SA), 0.25 and 0.50 mM abscisic acid (ABA) and methyl jasmonate at 0.25 and 0.50 mM (MeJA). Bioactive compounds and fungal growth were assessed over 12 days of storage at 4°C. RESULTS: Both concentrations of SA and MeJA significantly suppressed weight loss, decay and respiration rate and 0.50 mM ABA also reduced decay. Both concentrations of SA retarded color development, and total soluble solids content was enhanced by 0.50 mM ABA and MeJA treatments. The most effective treatments for preserving firmness were 0.25 mM MeJA and 4 mM SA. Reduction in loss of ascorbic acid and bioactive compounds during storage was achieved using the highest concentrations of SA, ABA, and MeJA. Fungal growth was suppressed by all treatments but the best treatment was MeJA at both concentrations. CONCLUSIONS: All three plant growth regulators reduce postharvest changes in strawberry but effects differ amongst the treatments.
