For the first time, organogenesis and physiological characteristics of Fragaria ananassa microclones (cvs. ‘Alpha’ and ‘Solnechnaya polyanka’) under the influence of mechanocomposite (MC) based on rice husks amorphous silica and flavonoids of green tea during the multiplication stage in in vitro conditions were studied. The addition of the MC (0.0, 2.5, 5.0 and 10.0 mg·L-1) to the Gamborg- Eveleg’s basal salt medium supplemented with 0.75 mg·L-1 6-benzylaminopurine has shown beneficial action on processes of organogenesis followed by enzymatic, photosynthetic, and hormonal activities of in vitro cultured strawberry plantlets. In both cultivars, the high frequency of proliferation (100 %) and maximum number of axillary shoots increased by 1.8–2.0 times on medium supplemented with 5.0 mg·L-1 MC. The concentrations of 2.5 and 5.0 mg·L-1 MC were optimal for obtaining plantlets with high physiological state in in vitro conditions. The results may be used for the development of production systems for a healthy planting material using biotechnological approaches and recommended for commercial strawberry micropropagation.

A mathematical model has been developed for the dependence of the solubility of pea flour protein on technological factors (concentration of enzyme preparations, duration of fermentation, hydromodule). The optimal technological parameters were determined at 1 + 2 stages of fermentation (concentration of enzyme preparations 170 units/g of DS or 1.5 %/g of protein, duration of fermentation was 4 hours, water module 1:15), at which the solubility and yield of pea protein reached 60 % of total content in raw materials. New information has been obtained on the effect of ultrasonic treatment on a suspension of pea flour to increase protein yield by 23–24 % compared with a control sample with an ultrasound wave amplitude of 10 microns and a processing time of 3 minutes, the final solubility is 83–84 %. The resulting protein product was characterized by high protein content, complementary amino acid composition; it is recommended for use in food purposes.

A biotechnological assessment (growth, viability, preservation of regeneration potentials) of 16 clones of different birch and poplar species, hybrids and polyploids under saline NaCl conditions in vitro culture was carried out. Three methods of selective exposure to the stressor were tested: chronic (0.2 % NaCl), stair-step (staged increase in the NaCl content in the nutrient medium from 0.2 % to 1.0 %) and hard (1.0 % NaCl). An algorithm for the formation of a selective in vitro system for differentiation and selection of birch and poplar resistant clones under conditions of artificial salinization is proposed.
USING THE UNIFIED THEORY OF ACCEPTANCE AND USE OF TECHNOLOGY (UTAUT) MODEL TO DETERMINE FACTORS AFFECTING MOBILE LEARNING ADOPTION IN THE WORKPLACE: A STUDY OF THE SCIENCE MUSEUM GROUP
Authors: Welch Ruel , Alade Temitope , Nichol Lynn
Published: October 2020

It has been observed that mobile learning (mLearning) in institutions like Museums in the United Kingdom (UK) has been underutilized. mLearning usage could potentially increase productivity by delivering just-in-time technical knowledge to the science museum group (SMG) staff. This study uses the unified theory of acceptance and use of technology (UTAUT) model to determine factors affecting mLearning adoption at the SMG. Two research questions were formulated based on an adaptation of the UTAUT model. 1) What are the determinants of behavior intentions to use mLearning at the SMG? 2) Does gender or age have a moderating effect on the factors that determine behavior intentions to use mLearning at the SMG? 118 respondents were surveyed from the SMG. Data obtained were analyzed using Structured Equation Modelling on IBM SPSS 20 and Amos version 25. Results indicate that the UTAUT constructs, performance expectancy, effort expectancy, social influence and facilitating conditions are all significant determinants of behavioral intention to use mLearning. A newly proposed construct, self-directed learning was not a significant determinant of behaviour intentions. Further examination found age and gender moderate the relationship between the UTAUT constructs. These findings present several useful implications for mLearning research and practice for ICT service desk at the SMG. The research contributes to mLearning technology adoption and strategy.

Introduction and Objective: To determine the prevalence of emotional and behavioral problems among siblings of children with chronic neuromuscular illnesses by using validated parent completed assessment tool.
Method: It is a cross-sectional study conducted in a tertiary care hospital from over a period of 34 months. Siblings of children with chronic neuromuscular illnesses were serially recruited while attending pediatric OPD and IPD. Parents were interviewed and requested to fill the Strength and Difficulty Questionnaire (SDQ) to assess and analyze emotional and behavioral problems among siblings.
Results: Study included 171 siblings of children with chronic neuromuscular illnesses. Of 171 siblings, 124 (72.51%) had normal scores, 25 siblings (14.62%) were in borderline range and remaining 22 (12.87%) had abnormal values. The mean ± SD of SDQ score was 12.41 ± 3.6 with median score of 11. There was no significant difference between total SDQ scores of male vs female siblings (p value= 0.229) or between birth order of the sibling or GMFCS class of the affected child to emotional and behavioural problems. Subgroup analysis was not possible because of small sample size.

Published: October 2020

The experimental research carried out and described in this paper aimed to obtain thin films from copper oxides and their characterization from the structural point of view and the optical and electrical properties. To obtain the copper films, a PVD spray deposition system was used, consisting of a vacuum chamber with a capacity of 2 liters, a planar magnetron with ferrite magnets (40x22x9) neodymium (15x8), a vacuum pump with sliding blades, a variable source of direct current of voltage 100 - 600 volts. The atmosphere used for plasma maintenance during deposition was argon rarefied in a pressure range between 3·10-2 - 8·10-3 mbar. The deposits were made on glass plates. The films thus obtained were subsequently subjected to oxidation at temperatures of 200, 300 and 450 °C. It was found that the transparency of the films increases with the oxidation temperature from 1.464 * 10-4 for 200 ºC to 0.5 for 450 ºC and the surface electrical resistance also increases from 0.984 Ώ for 200 ºC to 3882857,1428 Ώ for 450 ºC. With increasing spray power, transparency and surface strength decrease.

Los procesos de familia desde la óptica del acceso a la justicia: hacia la consolidación del derecho procesal de familia
Authors: Celis Vásquez Marco Antonio
Published: October 2020

El derecho procesal de familia se ha consolidado en la última década, al reconocérsele doctrinariamente características y peculiaridades propias y la existencia de principios autónomos, así como la exigencia de contar con un juez capacitado de manera especial en este tipo de procesos, con una formación técnico-jurídica en asuntos de índole familiar y una visión completamente distinta a los demás procesos civiles. Es importante recalcar la visión que con respecto al juez posee el doctor Rogelio Llerena Quevedo, quien señala que: «el juez intérprete y administrador ecuánime de la justicia, solo puede ser comprendido como uno entre los mejores seres humanos. Esto implica que aún siendo el mejor, sigue siendo humano y, por lo tanto, susceptible de error. Por tales razones, debe siempre tener como guía un Código de Ética que sirva de guía para un buen juez» (Llerena Quevedo, Rogelio).
Tribunal Constitucional vs. Poder Judicial (a propósito de un proceso competencial)
Authors: Malpartida Castillo Víctor
Published: October 2020

Las fricciones entre el Poder Judicial y el Tribunal Constitucional no son nada nuevo dentro del derecho comparado. Como recuerda García Belaúnde han existido por lo menos desde la década del sesenta en Italia, de donde nos viene el nombre de «Guerra de las Cortes», ya que el máximo órgano judicial en el mencionado país es la denominada Corte de Casación y el órgano de control constitucional concentrado se llama Corte Constitucional. Dicho fenómeno se repetiría en España y también en Colombia, en donde se conoce al incidente como «choque de trenes». En nuestro país, discutir si el Tribunal Constitucional es jerárquicamente superior respecto al Poder Judicial es hacer mención de los alcances del artículo 201.o de la Constitución vigente que define al primero como autónomo e independiente y como «el órgano de control de la Constitución».

Pero, en estricta relación con lo señalado, este trabajo también hace un tratamiento del precedente vinculante, figura que a partir del Código Procesal Constitucional se introdujo en el artículo VII de su Título Preliminar y que el Tribunal Constitucional en su Sentencia N.o 0024-2003-AI/TC ha definido como «aquella regla jurídica expuesta en un caso particular y concreto que el Tribunal Constitucional decide establecer como regla general; y, que por ende, deviene en parámetro normativo para la resolución de futuros procesos de naturaleza homóloga», y que por tanto, «el precedente constitucional tiene por su condición de tal, efectos similares a una ley. Es decir, la regla general externalizada como precedente a partir de un caso concreto se convierte en una regla preceptiva común que alcanza a todos los justiciables y que es oponible frente a los poderes públicos». Finalmente, se plantea una reflexión acerca de la cosa juzgada constitucional.
La función económica de la contratación masiva
Authors: Rodríguez Chávez Reyler Yulfo
Published: October 2020

Mediante el presente ensayo se aborda el tema de la contratación masiva desde la perspectiva del análisis económico del derecho (AED), con la finalidad de delinear las pautas que fundamentan la función económica que viene cumpliendo esta forma de contratación dentro del actual escenario de intercambios económicos, caracterizado por la presencia de dos factores con especiales distinciones, la sociedad de masas y la producción masiva de bienes y servicios. Entre ellos, es la contratación masiva a través de sus diversas formas, como los contratos por adhesión y las cláusulas generales de contratación, la que permite entrelazar las transacciones mercantiles consolidando vínculos jurídicos entre los empresarios a cargo de la oferta de los bienes y servicios y los consumidores demandantes de aquellos bienes y servicios. La contratación masiva, a la vez que dota de seguridad jurídica a aquellas relaciones jurídicas de intercambio masivo, las hace rápidas y eficientes, acorde a las exigencias del mercado. Es por ello que esta forma de contratación no solo es un «medio fin» que permite entrelazar y constituir ambos polos (empresarios y consumidores), sino que además, al consolidar el andamiaje jurídico del contrato, permite reducir costos de transacción en tiempo, dinero, esfuerzo. De allí que la contratación masiva también constituya un «fin en sí misma».
Víctima e imputación objetiva
Authors: Teixidor Vinjoy Duvi Alfredo
Published: October 2020

Se ofrece una aproximación a la teoría de la imputación a la víctima, desde la imputación objetiva de comportamiento, con énfasis en el giro interpretativo que significó la asunción del finalismo, reubicación sistemática del dolo, la imprudencia, e incidencia de la teoría de imputación objetiva, en la expresión de sentido y significado de la tipicidad. El enfoque discurre desde la evolución histórica de la concepción de imputación, hasta el estado actual de la discusión en materia de: a) determinación del ámbito y contenido concreto de sentido en la norma, esto es, la imputación objetiva, y b) la incidencia del principio de autorresponsabilidad de la víctima en la imputación al tipo objetivo, como «experiencia normativa recalcitrante». Con ello, se pretende: a) poner el énfasis en la normativización de la tipicidad objetiva y subjetiva, como presupuesto del juicio de referibilidad del comportamiento al desvalor, y b) jerarquizar el principio fundamental de proporcionalidad en el ámbito de atribución del comportamiento a su autor, en situaciones de organización conjunta. A partir de su evolución dogmática, se analizan casos concretos, identificando criterios de imputación a la víctima aplicados por los Tribunales; visión pragmática de la dogmática penal que justifica una propuesta de estructuración de la infracción al debido cuidado como instituto organizacional normativo, a partir de una reinterpretación de los arts. 18 y 59 inc. 2 del CP. Con ella, se procura: a) evitar que la imprudencia se considere con independencia del principio de auto-responsabilidad de la víctima, y b) facilitar una solución finalística-normativa de tipicidad conglobante, a los problemas que plantea la adscripción objetiva y subjetiva del comportamiento, y su expresión de sentido desde el desvalor de acto.

The studies associated with the management of intellectual capital have acquired great relevance as a result of the dynamics generated by intangible assets in companies and their market value. There is evidence of a change in the values and attitudes of management levels (middle managers) and personnel in general on the aspects that favor the adequate management of the different types of human capital (intellectual, structural and relational or social). This paper presents the result of a suvey to a sample of 69 companies of differnte sizes and turns in the city of León, Guanajuato, Mexico on the behavior of some indicators of intellectual capital management based on the Intellectus Model. Finally, the main findings of the study allows to observe important data such as the levels of integration and motivation of staff, promotion mechanisms, level of involvement in decision making, levels of schooling, propensity for change or improvement in products and processes, knowledge transfer in the form of intangible assets such as trademarks and patents that allow them to increase their chances of permanence and growth in the long term.

Published: October 2020

This study aims to examine parents' perceptions of distance learning in response to the closure of many schools due to the Covid-19 pandemic. This research uses a qualitative approach with descriptive methods. The research subjects consisted of parents of elementary school students, and the data were collected using interview techniques. This study shows that distance learning in a research context is organized in the form of online and offline learning. For parents, the current learning approach is something that must be lived and supported in the absence of other options. Even though parents do not have negative perceptions, distance learning contributes to increasing the burden on parents or families economically, including psychological and social aspects. The lack of parental involvement and support in the learning process of children at home is generally due to the lack of time and the inability of parents to become teachers for their children at home. Actions to accompany and support children's learning at home are carried out in the form of providing internet packages, helping children to master the learning materials, and participating in completing assignments or tests given by the teacher. The surprising finding of this study is that children's learning motivation has decreased, and for the remainder of the school year, parents expect the government to reopen it so that children can study again in class and meet with their peers.
Behavior of Steel Plate Girders with Deep Section under Dynamic Effect
Authors:   lecturer at Civil Engineering Department, Higher Institute of Engineering and Technology, Kafr-elsheikh, Egypt., El Dehemy Hanady
Published: October 2020

Having a minimum mass, equal-sized flanges and no web stiffeners is the most economical plate girder to fabricate. As with rolled I-sections, for a given section modulus a section with a greater depth will have a lower mass than one with a smaller depth, except in some instances where a thicker web is required in the deeper section. A wider flange plate to resist the buckling tendency may be necessary to use, when the compression flange is laterally unrestrained, but this will add to the cost because of the more difficult assembly procedure. In order to arrive at a minimum-mass cross section as much as possible of the material should be located in the flanges and as little as possible in the web, consistent with shear requirements. There is usually an advantage, however, in using a somewhat thicker web in order to reduce welding distortion, or to avoid the use of or number of stiffeners. It can be shown that for a given web depth to thickness ratio the minimum-mass cross section is that in which the area of the two flanges combined equals that of the web, i.e. 2Af = Aw.An important consideration in cost reduction is the use of preferred plate widths and thicknesses for the flange and web elements.

The Eddy current testing (ECT) technique is one of the non-destructive testing (NDT) techniques which is sensitive to the unintended signal such as lift-off (LO) height effect. The output voltage of signal defects with different thicknesses of test materials (i.e., Copper, Brass and Magnesium Alloy) can be determined from the optimum distance of LO height of the ECT technique. Previously, an established frequency was determined for these particular materials (i.e., Copper = (5.00-5.25) MHz, Brass = (4.75-5.25)MHz and Magnesium Alloy= (4.75-5.00)MHz). The frequency then generated the established voltage signal of the ECT technique. The acquired optimum distance of LO height for these materials is approximately 2mm. The findings from this established technique indicated that the determined optimum distance of LO height can find the output voltage signal of the defects as well as to detect the thicknesses.

Various research are being carried out to find a suitable replacement for the non-bio degradable plastic reinforced composites, which has a negative impact on the Environment. A similar attempt is made to present an overview of recent research efforts addressing the properties of isophthalic polyester based Bamboo fabric mat as a replacement for E-glass fabric. The Bamboo fabric is made water repellent and the properties are promoted through mercerization process. The mercerization process is done using 8% of sodium in water to form the sodium hydroxide (NaOH). The property of the fabric is further promoted by adding charcoal, during the hand moulding process. The composite material is developed with the help of isophthalic polyester resin with 2% of accelerator and hardener used along with it. Experiments are carried out as per ASTM standards to find the mechanical properties namely, tensile strength and modulus, flexural strength and modulus, and impact strength. In addition to mechanical properties, water absorption capacity and the rate of burning of the composites is also studied. Further, fractured surface of the specimen is subjected to morphological study using scanning electron microscope. With help of the research and study, it can be found whether the isophthalic resin-based bamboo fabric mat can be used as an alternate for E-Glass fabric composite in various applications such as automobile and structural applications.

The base of the proposed antenna is its Hybrid structure, which generates fundamental TM, TE and higher order modes that yields an impedance bandwidth of 119%. Proposed antenna provides a frequency range from 4.2 to 16.6 GHz with a stable radiation pattern and low cross polarization levels. Peak gain of 5.5 dB and average efficiency of 90% is obtained by the design. Antenna is elongated on a FR4 substrate of dimension 20 x 24x 2.168 mm3 and is particularly suitable for C band INSAT, Radio Altimeter, WLAN, Wi-Fi for high frequencies.

The text summarization is a technique where the original large text is condensed into smaller version without changing its abstract meaning. The text summarization is done on the common foreign and regional languages typically, but infrequent work has been observed for the Marathi language. As the amount of e-contents on web is increasing drastically, the users are facing difficulty to read the newspaper articles with extraction of its different perspectives with sorting. We are focussing on educational, Political and sports news for summarization, which will be helpful for students who are appearing for competitive exams. This paper explores the preprocessing techniques for Marathi e-news articles.

In the present industrial scenario, Aluminium and its alloy based composites have more importance in the growing fields of engineering. Aluminium reinforced metal matrix composites are broadly speaking desired because it has the excessive strenth along with less weight, hardness, corrosion resistance, fatigue and creep resistance. The Al composites are focused to use in aerospace, automobile and also in structural domain because it gives good strength with less weight. This paper discussed about the mechanical residences of Aluminium 7075 alloy strengthened with SiC and TiC. Stir casting process was utilized for fabrication of composites and composite specimens are subjected to tensile test by using Universal Testing Machine. The composite hardness was tested by using Brinell hardness tester and the Charpy impact tester used for findings the impact strength. An experimental results are compared with unreinforced alloy of Al 7075. Micro structural characterization confirms the particles of reinforcement are distributed to the entire structure of matrix. The experimental result shows the mechanical properties slightly increased by varying wt% of reinforcements in the matrix material. The better tensile strength (252MPa), hardness (83HB) and impact strength (4.6 Joules) is obtained by the composition of 60% wt of Al 7075, 20% wt of TiC and 20 %wt of SiC.

, Sign languages have their own linguistic structure, grammar and characteristics, and are independent of the rules that govern spoken languages. They are visual languages that rely on hand gestures as well as on bodily and facial expressions. Sign languages in different countries are vastly different from one another, so enabling easy communication is important: not just to break the barrier between hearing and deaf individuals, but also between people who do not sign in the same language. In India, sign language plays an important role in the field of communication among dumb and deaf people. There are different signs associated for communication in every country as per their convenient gestures. Automatic sign language gesture recognition is an approach for recognizing gestures and converts it to its actual meaning and convey either through speech or text as per requirements. Here the system is based on Prewitt Edge Detection that possesses the gestures of sign language and helps to recognize and assign their meanings. The Prewitt is second order derivative that has been used in image processing and computer vision, in the form of edge detection or extraction algorithms where it creates gradient of horizontal and vertical magnitude. System also uses certain pre-processing filtration technique such as morphological dilation for better feature extraction.

A study on engineering in sub-Saharan Africa revealed that engineering is pivotal for economic and social development of any country. This is profound as it underscores the potentials embedded in engineering education for excellence and relevance in Africa. This has not been the case in Africa, as the region has not developed evenly with other countries from the Global South. Hence, the impetus for chaos engineering as a panacea to excellence and relevance in engineering education in Africa. Chaos engineering has been defined by various authors and one of the profound definitions is that chaos engineering is the discipline of experimenting on a distributed system with the intent to build confidence in the system`s capability to withstand turbulent conditions during production. This study therefore looked at chaos engineering, its history and applicability and conceptualize it as a pathway for excellence and relevance in engineering education in Africa. Findings from the that engineering is pivotal for economic and social development of any country but it has not resulted to such in Africa which necessitates chaos principles. It was found out that experimentation is a basic principle of chaos engineering while the advanced principles are hypothesizing about steady state, vary real-world events, run experiments in production, automate experiments to run continuously, minimize blast radius. These all were conceptualized as the pathway to excellence and relevance in engineering education in Africa. The study recommended that there is a need to intensify effort on researching more into chaos engineering in Africa.
