Published: July 2021

Among the nutrients, nitrogen (N) is the element required in greater quantity by the bean plant. Depending on the cultivar, it has greater or lesser N-fixing capacity. The aim of this work was to evaluate the performance of two common bean cultivars under nitrogen topdressing in corn succession, on yield components and yield. The experiment was carried out in randomized blocks in a 2x5 factorial scheme, the first factor being the common bean cultivars (IPR Campos Gerais and BRS Estilo) and the second factor the nitrogen rates (0, 30, 60, 90 and 120 kg ha- 1), with four repetitions. At harvest, plants were collected in one meter, in the useful area of ​​each subplot to determine: number of plants per meter; number of pods/plant; number of grains/plant; number of grains/pods; mass of a thousand grains and productivity. The cultivars differed regarding the number of pods per plant, grains per plant and yield, but they were equivalent for the number of plants per meter, grains per pod and mass of a thousand grains. Comparing the production component number of pods per plant and grain yield, it is concluded that the cultivar that produced the highest number of pods per plant and showed the highest yield was BRS Estilo. There were differences between the treatments for the two cultivars, only in the yield obtained. The highest yield averages were obtained in treatments with doses above 60 kg ha-1 of N.

Published: July 2021

A Educação Física aparece com grande responsabilidade na escola, estruturando o ambiente adequado para a criança vivenciar e sentir sua relação com o meio. Dentro do cenário apresentado, as atividades psicomotoras que levam a criança a tomar consciência de seu corpo, devem ser praticadas desde o início da infância. Objetivou-se verificar os efeitos da psicomotricidade na Educação Física e pratica de exercícios físicos para o desenvolvimento integral da criança. Este trabalho foi realizado por meio de leitura exploratória de materiais bibliográficos, baseada na análise de livros, revistas, artigos de sites (scielo e google acadêmico) que abordam a importância da psicomotricidade como ferramenta na Educação Física. Os resultados evidenciados foram que a psicomotricidade desenvolve as habilidades motoras quando trabalhada nas aulas de educação física, e colabora para o desenvolvimento afetivo, cognitivo e motor. Esse processo, ocorre gradativamente, ao longo do crescimento e maturação da criança. Deste modo, a psicomotricidade atua fornecendo subsídios para adaptação da criança as suas necessidades básicas. E assim, quando trabalhada no contexto escolar, estimula o desenvolvimento harmonioso e integral do ser. Ao verificar as pesquisas e estudos em torno de crianças com e sem dificuldades motoras, pode se concluir que a intervenção motora causa progressos consideráveis no desenvolvimento motor, cognitivo e afetivo, e que estes por sua vez, colaboram com as outras áreas de aprendizagem (leitura e escrita por exemplo) e com desenvolvimento integral da criança.  As atividades psicomotoras devem ser utilizadas como aparato da educação física na educação infantil, já que existe, por parte da literatura um consenso de que tais atividades auxiliam a criança no seu desenvolvimento global.

Published: July 2021

El viaducto sobre el barranco de Erques (Tenerife) es un puente formado por dos arcos con tablero intermedio de 110 m de longitud y 17,7 m de altura de clave. Cada arco está compuesto por dos tubos de acero, de 1020 mm de diámetro, rellenos de hormigón expansivo. En este artículo se describe el programa experimental que ha servido de base para la ejecución de los arcos del viaducto. También se detalla la instrumentación realizada para registrar las deformaciones longitudinales y circunferenciales de los tubos y las temperaturas de los mismos durante el proceso de hormigonado y posterior endurecimiento, con el objeto de estimar el efecto expansor del hormigón y comprobar si los resultados son acordes a los determinados en la investigación previa.

La caracterización del hormigón expansivo para su aplicación en estructuras tubulares requiere realizar ensayos de expansión libre y confinada del hormigón para ajustar la deformación de expansión necesaria. Estos ensayos se complementaron con otros para determinar la carga de deslizamiento del núcleo de hormigón dentro del tubo de acero a temperatura ambiente y con calentamiento uniforme y diferencial, realizados para evaluar la incidencia de los efectos térmicos en la resistencia a esfuerzos rasantes de la interfase tubo-hormigón.

Multidimensional Assessment of India’s Manufacturing GVC Linkages
Authors: Dutta Sourish
Published: July 2021

The whole purpose of this part of my research is to quantify the degree of value transformation taking place domestically between imports and exports due to India’s GVC integration in the manufacturing sector. The consideration of using gross imports & exports data to draw a quantitative inference about India’s GVC potential leads to a different conceptualisation of the existing production process regarding knowledge, learning, and upgrading. Traditional trade theories assume that the whole production process of a product is taken place in one country and is marketed in another. However, the notion of GVC trade is different – quantifying how much of India’s export value is contributed by imports and how much India is adding value to exports. The basic concept is "import to export" or I2E.

Authors: Ponomarenko Natalia , Voznyakovska Christina , Nemish Julia
Published: July 2021

Summary
The purpose of the article is to study the problematic aspects of the functioning of the electronic public procurement system ProZorro in Ukraine and to develop proposals for minimizing abuses in the field of tender procedures. Research methods: The article uses general scientific research methods, in particular: synthesis analysis – in the study of scientific literature and determining the features of the electronic public procurement system ProZorro; economic and statistical analysis and comparison – with indicators of public procurement in Ukraine; generalization – when developing recommendations for minimizing abuses in the field of public procurement within the electronic system ProZorro. Scientific novelty: is to determine the main mechanisms of abuse in the field of public procurement in order to obtain illegal benefits: the fragmentation of contracts and the development of sub-threshold trade procedures and justification of ways to minimize them. In particular, in the article
It is substantiated that non-competitive tender offers carry high corruption risks and lead to inflated prices for the supply of goods, services and works. It is proposed to amend the Law of Ukraine «On Public Procurement» in order to prohibit the conclusion of additional agreements after the tender; prohibition to change the conditions of the tender and tender documentation after the announcement of tenders; prohibitions to combine goods into one lot and set maximum payment terms for delivered goods for more than 30 calendar days.
Conclusions: The study concludes that the electronic public procurement system ProZorro has a positive impact on the development of public procurement in Ukraine, as it increases the transparency of bidding and tender procedures, expands opportunities for participation in tenders of small and medium-sized businesses and more. However, shortcomings, first of all, in the law enforcement and judicial system of Ukraine are caused by frequent cases of corruption schemes in the public procurement system both within the ProZorro system and outside it. Elimination of corruption schemes in the public procurement system is possible subject to amendments to the Law of Ukraine «On Public Procurement».
Keywords: public procurement, ProZorro, tender, tender offer, electronic bidding, competitive and non-competitive procedures.

Published: July 2021

Agricultural production is an important and at the same time the most risky type of economic activity. Its reproductive process is associated with natural and climatic, biological and financial factors, the action of which in many cases is difficult to forgive and control. Crop production is particularly affected by cumulative natural risks. One of the ways to minimize agricultural risks is to use crop insurance as an important means of ensuring the riskiness of agricultural production from probable natural and weather factors. The pricing mechanism for crop insurance services is substantiated, based on the improvement of the insurer’s tariff policy when conducting crop insurance, which is implemented through a system of actuarial calculations and taking into account the peculiarities of insurance in the process of crop production. The possibility for insurance companies to carry out high-quality selection of agricultural risks, stimulating agricultural producers to insure, is analyzed. Actuarial balance has been studied as a necessary condition for improving the tariff policy of crop insurance, which should be based on such principles as: equivalence of insurance relations; admissibility; stability of insurance rates over a long period of time and expansion of insurance liability. The calculation of insurance rates has been improved by taking into account the availability of prices for insurance services, depending on the number of possible risks transferred to insurance and the amount of financial resources accumulated by the insurer, which should be sufficient to reimburse crops under crop insurance contracts. Actuarial balance is identified as a necessary condition for improving the tariff policy of crop insurance. The principles of insurance tariff policy to improve the calculation of insurance rates and the application of actuarial models in the field of crop insurance. Key words: tariff policy, insurance tariff, actuary, actuarial mathematics,

Seismic data provide evidence about hydrocarbon deposition, geological and geophysical subsurface information, including geomechanical aspects. Deriving and understanding geomechanical properties is crucial for reservoir management as it can avoid drilling and production-related problems that cause environmental impacts associated with land subsidence and uplift. The Poison's ratio (PR), Young Modulus (YM), and elastic moduli for a reservoir block were estimated using 3D seismic pre-stack data and well data. 3D Mechanical Earth Models (MEM) were also developed using the well logs, seismic horizons, and drilling data. Seismic data-derived geomechanical properties were compared with the mechanical earth models for the first time for this field. Well-tie analysis was used for inversion of 3D seismic data to extract detailed waveform and amplitude information. The brittleness index of the subsurface layers was estimated, which is a critical rock property that provides information about rock hardness and fragility phenomenon. The brittleness index has a diverse range from 5-35%, with significant contrast at shallow zones. PR and YM models generated from 3D MEM and seismic data have average values of 0.2 -0.6 and 5 - 28 GPa with significant contrast from shales and carbonates. The study recommends that the drilling through these problematic zones should be avoided to avoid wellbore problems that cause challenges in maintaining wellbore integrity and reservoir management in the North-Heera field, Mumbai Offshore Basin.

Sustainable operations are concerned with the eco-friendly system to postulate intergenerational equity on social, economical, and environmental responsibility. This paper addresses the deterioration with a preservation strategy without compromising the environmental performance of the product. Also, the loss due to deterioration is managed completely with the idea of salvage trade. Furthermore, the upcoming demand is assumed to be “price and environment-sensitive”. This model maximizes the seller’s total profit by optimizing the unit selling price and minimizing the investment to maintain the environmental performance of the product and preservation technology at the same time. A numerical example and related graphs are illustrated to validate the model.

In the present work, we propose a novel modulation scheme for 5G wireless communication system. Our contribution is to combine PM-OFDM (Phase Modulation Orthogonal Frequency Division Multiplexing) and CDMA (Code Division Multiple Access) to exploit their distinctive advantages. On the one hand, PM-OFDM is an effective technique to combat multipath fading effects. On the other hand, CDMA can serve multiple users who are using the same resources of time/frequency. The aim is to make a combination of PM-OFDM and CDMA techniques. In this paper, the OFDM-CDMA scheme and its PAPR (Peak-to-Average Power Ratio) statistics are reviewed. In this paper, the proposed scheme PM-OFDM-CDMA is described and its performances in terms of PAPR, power spectral density, and BER (Bit Error Rate) are analyzed. Moreover, MMSE (Minimum Mean Square Error) equalizer is used to avoid multipath and noise effects simultaneously. The simulation through AWGN (Additive white Gaussian noise) and Rayleigh channels is performed using MATLAB. From the simulation results, we observed that PM-OFDM-CDMA is an efficient technique in terms of energy consumption (PAPR = 0dB). Besides, CE-OFDM-CDMA offers high spectral efficiency with low BER due to its low PAPR. In CE-OFDM-CDMA method, the shape of the spectrum varies according to the value of the modulation index h. The band occupied by the spectrum increases with the value of h. Therefore, CE-OFDM-CDMA could be considered as a suitable technique for 5G applications.

This paper explores several possible hybridized techniques to supply electrical energy at remote locations where the utility grid extension is found uneconomical. In this work, diesel-generator (DG) is combined with the various renewable energy resources (RES) and multiple storage facilities, such as (i) proton exchange membrane fuel cell (PEMFC) and hydrogen energy storage (HES), (ii) PEMFC, HES, and Solar PV, and (iii) HES, Solar PV, PEMFC, HES, and battery storage system (BSS), respectively, to achieve the best hybrid solution to supply electrical power in remotely located area efficiently. The Homer Pro software developed by the national renewable energy laboratory is used in this paper for conducting the proposed analysis. The problem is formulated as a multi-objective optimization problem to minimize the cost and greenhouse gas emissions. Three performance indices or objective functions, namely net present cost (NPC), levelized cost of energy (LCOE) and unmet load, have been evaluated for these three hybridizations to determine the best alternative to overcome the energy crunch, which is existing especially in remotely located area. The comparative analysis of the estimated performance parameters has revealed that the hybridization of DG with Solar PV, PEMFC, HES, & BSS provides smaller values of NPC (in US $), LCOE (in US $/kWh), and unmet load. Furthermore, hybridization of DG with Solar PV, PEMFC, HES, & BSS results in the lowest pollutant emission with zero unmet loads and energy wastage. Therefore, in this study, hybridization of DG, Solar PV, PEMFC, HES, & BSS is recommended as the best alternative to supply electrical power efficiently and economically to remote areas. In this stand-alone work mode of operation of DG is considered as a reference system and named ‘Combination 1’. The LCOE and NPC of the best suitable HPS are obtained as 0.50193 US $/kWh and 35200000 US $, respectively. As a result, the system's emission is reduced by 94% compared with the base case (combination 1).
Harris Hawks Optimization for Optimum Design of Truss Structures with Discrete Variables
Authors: Al-Bazoon Mustafa
Published: July 2021

This article investigates the use of Harris Hawks Optimization (HHO) to solve planar and spatial trusses with design variables that are discrete. The original HHO has been used to solve continuous design variables problems. However, HHO is formulated to solve optimization problems with discrete variables in this research. HHO is a population-based metaheuristic algorithm that simulates the chasing style and the collaborative behavior of predatory birds Harris hawks. The mathematical model of HHO uses a straightforward formulation and does not require tuning of algorithmic parameters and it is a robust algorithm in exploitation. The performance of HHO is evaluated using five benchmark structural problems and the final designs are compared with ten state-of-the-art algorithms. The statistical outcomes (average and standard deviation of final designs) show that HHO is quite consistent and robust in solving truss structure optimization problems. This is an important characteristic that leads to better confidence in the final solution from a single run of the algorithm for an optimization problem.
