Authors: Vargas Emgelberth 
Published: July 2020

El siglo XXI ha representado una era de cambios, así como de nuevas maneras de ver o percibir las realidades desde las miradas de los otros. Es así que se presentan nuevos paradigmas y parte de ello se refleja en las innovaciones tecnológicas que se hacen perentorias en cada uno de los ámbitos donde se desarrolla la sociedad. En este sentido emerge la educación tecnocientífica (ETCS), como una de esas innovaciones que se configuran en una necesidad para las representaciones sociales de los actores educativos en el contexto universitario. La ETCS se refiere al conjunto de disciplinas que se engranan para estudiar aspectos sociales de la ciencia y tecnología, concebidas como áreas indispensables en el aquí y ahora, convirtiéndose en el eje central para poder desarrollar en las personas una cultura tecnocientífica.Este artículo posee como eje teleológico central, develar los fundamentos explicativos de las representaciones sociales de los actores educativos, acerca de la alfabetización tecnocientífica en el contexto universitario de la Universidad Nacional Pedro Henríquez Ureña (UNPHU) en Santo Domingo, República Dominicana. La metodología se estructura desde la episteme fenomenológica hermenéutica.Para ello, se seleccionarán tres actores educativos pertenecientes al Departamento de Ciencias. La obtención de la información se hará a través del análisis documental y la técnica de la entrevista en profundidad, que posee como instrumento al guión de dicha entrevista. Se pudo conocer que desde los pensamientos y representaciones sociales de los actores educativos, se edifican fundamentos que denotan la relevancia de propiciar en el contexto universitario la educación tecnocientífica; y con ello la alfabetización de modo imperante en una era donde la ciencia y la tecnología deben ser apoyadas desde los entes gubernamentales, para poder propiciar el desarrollo de un país.

For homogeneous fertilization and crop management practices, this work hypothesized that texture could influence cereal yield, particularly in dry regions. Particle size analysis could help improve knowledge of the soil-plant relationship to obtain favorable conditions for better yield. The objective of this work is to develop a single granulometric index for durum wheat (Triticum durum) that is well correlated with yield. For this purpose, 350 independent samples of cereal soils from eastern Algeria were taken and the recorded yields were linked to these samples. The cutoff yield, which separates sub-populations with acceptable yield from those with less acceptable yield, was determined from the inflection point of the cumulative variance ratio functions related to yield by the Richards’ equation. The result obtained is 2.0 Mg.ha−1, with a theoretical critical chi-square value of 4.2, close to 4.6, which is the critical value of r2granulo as obtained by the Cate-Nelson procedure. The five-granulometric indices were found to be symmetrical around zero as follows: ±0.83 for clay (IC), ±1.73 for fine silt (IFL), ±0.31 for coarse silt (ICL), ±0.44 for fine sand (IFS), and ±1.30 for coarse sand (ICS). The two fractions that most influence the textural imbalance are fine silt (IFL) and coarse sand (ICS), with a contribution of 41% and 37%, respectively. The critical single imbalance index r g r a n u l o 2 can be used for determining cereal suitability for soils in the arid region of eastern Algeria. The lower the r g r a n u l o 2 is, the better the soil for cereal crops.
Retrieval of Soil Moisture Content Based on a Modified Hapke Photometric Model: A Novel Method Applied to Laboratory Hyperspectral and Sentinel-2 MSI Data

Published: July 2020

Soil moisture is the crucial carrier of the global hydrologic cycle and the dynamic energy balance regulation process. Therefore, it is of great significance to monitor surface soil moisture content (SMC) accurately for the study of the natural ecological environment. The Hapke model is the most widely used photometric model in soil remote sensing research, but the development of this model is limited by the lack of valid multi–angular data. The main innovations of this paper have two aspects: (1) A novel soil moisture retrieval approach based on the Hapke (SMR–Hapke) model is derived by exploring the relationship between single scattering albedo (SSA) and SMC on the optical bands from 400 to 2400 nm. The performance of the proposed model was verified on a dataset consisting of four different soil samples, and the experimental results indicated that the inverted soil moisture from SMR–Hapke model coincided with the measurement values, with the R2 being generally more than 0.9 in the solar domain. (2) The SMR–Hapke model has been reduced to a linear form on the SWIR field and a physically-based normalized difference soil moisture index N D S M I H a p k e has been proposed. Based on the laboratory-based hyperspectral data, we compared the performance of N D S M I H a p k e with other traditional soil moisture indices using linear regression analysis, and the results demonstrate that the proposed N D S M I H a p k e had a great potential for estimating SMC with R2 values of 0.88. Finally, high–resolution SMC map was produced by combining the Sentinel–2 MSI data with N D S M I H a p k e . This study provides a novel extended Hapke model for the estimation of surface soil moisture content.

Ópera de mulher: projeto de encenação e interpretação musical
Authors: Viana Isabel , Oliveira José Luís de 
Published: July 2020

Na interpretação de uma obra musical cantada, em particular de uma ópera, o cantor-ator tem um papel determinante na transmissão não só das componentes informativas, a nível do texto musical e literário, mas também dos estados emocionais das personagens, através de indicadores ou marcadores não verbais. Neste artigo apresentamos uma proposta de encenação e os métodos que usamos para fundamentar teoricamente o projeto. Trata-se da interpretação de dez personagens femininas soprano de óperas italianas do século XIX, composto por duas árias de cada um dos cinco compositores italianos escolhidos: Lucilla: “Sento talor nell'anima” [Rossini, La scala di seta (1812)]; Anna: “Giusto Ciel in tal periglio” [Rossini, Maometto II (1820)]; Norma: “Casta Diva” [Bellini, Norma (1831)]; Elvira: “Qui la voce sua soave… vien diletto” [Bellini, I Puritani (1835)]; Marie: “Ciascun lo dice” [Donizetti, La Figlia del Reggimento (1839)]; Rita: “E’ lindo e civettin questo caro alberguccio” [Donizetti, Rita (1841)]; Gilda: “Tutte le feste al tempio” [Verdi, Rigoletto (1850)]; Oscar: “Volta la Terra...” [Verdi, Un Ballo in Maschera (1859)]; Anna: “Se come voi piccina io fossi” [Puccini, Le Villi (1884)]; Musetta: “Quando men vo” [Puccini, La Bohéme (1895)]. O espetáculo tem a duração de cerca de 45 minutos e tivemos particular atenção aos estados emocionais de cada uma das personagens, para a interpretação das respetivas árias, bem como a cenografia e os adereços.
Com este projeto, concluímos que, ainda que vocal e tecnicamente possa ser bem executada, não é possível realizar uma correta interpretação de uma ária sob o ponto de vista dramático sem conhecer previamente a personagem, a sua personalidade e, especialmente, os estados emocionais presentes em cada um dos momentos
El cuerpo sin órganos
Authors: Valencia García Eric 
Published: July 2020

Desde hace un par de años asisto a Intensidades de lectura, un grupo de estudio dedicado a El Anti Edipo, escrito por Gilles Deleuze y Félix Guattari. Acogido por Zona de Desgaste, espacio dedicado al estudio del arte contemporáneo, el grupo se ha ido integrando con asistentes de los más distintos perfiles, lo que ha permitido acercamientos desde campos que exceden a la filosofía y al arte. Pronto me encontré haciendo dibujos y esquemas para aproximarme a las ideas que los autores ofrecen. Como respuesta a la invitación a colaborar en El ornitorrinco tachado, retomo los bocetos anteriores para producir una pequeña serie de esquemas-pinturas basados en las páginas 11 a la 35 de la edición de Paidós (1985). El texto corresponde a una parte de la descripción del cuerpo sin órganos, un concepto filosófico que describe (dicho a muy grandes rasgos) cómo el deseo, en tanto productor de la realidad, es un objeto en disputa entre el individuo, lo social y los aparatos de poder. He incluido un código debajo de algunas imágenes que señala los conceptos utilizados así como las páginas del libro de donde surgen estas imágenes.
Doy cuenta de la deuda que este ensayo visual tiene con Intensidades de lectura y en particular con Sandra Sánchez, quién ha llevado una investigación de largo aliento sobre los potenciales estéticos y expresivos de los esquemas.
Parafraseando a los autores de El Anti Edipo, valga el esfuerzo por entender el deseo y encontrar en él posibilidades revolucionarias.
Evaluation of Compacted Laterite Soil Admixed with Cement and Hair Fibres as Road Construction Material
Authors: OLUREMI Johnson Rotimi , Adedokun Solomon Idowu , Yohanna Paul , Fadiran David A. , Azeez Idris O. 
Published: July 2020

A natural lateritic soil classified as A-5 (4) based on American Association of State Highway and Transportation Officials (AASHTO) soil classification system and ML-CL according to Unified Soil Classification System (USCS), was admixed with ordinary Portland cement and synthetic hair fibres (SHF) was evaluated as road construction material. Soil test specimens were made by admixing lateritic soil with up to 4% cement in 1 % step concentration and up to 12% SHF in step concentration of 2 % by dry weight of the soil and were subjected to British Standard Light (BSL) or Standard Proctor method of compaction, unconfined compressive strength (UCS) and California bearing ratio (CBR) tests. Results indicated a decrease in the values of optimum moisture content (OMC) while no general trend was established for maximum dry density (MDD). The values of UCS and CBR increased as the content of both cement and SHF increased. Analysis of variance (ANOVA) of the results shows some level of statistical significance on some geotechnical properties considered. Regression analysis on the results using Minitab R15 software shows that MDD, OMC, cement and SHF significantly influenced the UCS and CBR values of the stabilized soil with correlation coefficient value (R2) of 82.9 and 83.3% respectively. Based on the results, an optimal blend of 3% cement 9% SHF significantly improved the soil properties and is recommended for improving the geotechnical properties of cement/synthetic hair fibre treated lateritic soil as road construction material.
Implementation of Edge Detection Algorithm using FPGA Reconfigurable Hardware
Authors: Abed Sa'ed 
Published: July 2020

Digital image processing is known as computer manipulation of image, which includes algorithms like image enhancement and target reorganization. Some of these algorithms involve operations like convolution and edge detection, which requires high computation. Generally, the software running on processor performs these manipulations. To achieve higher computation performance in terms of execution time, these algorithms are implemented on reconfigurable hardware like FPGA. One can implement parallel architecture and pipelined architecture on FPGA to gain speed up. In this work, we provide a detailed description of implementing edge detection algorithm on SGI–RC100 platform. The algorithm is implemented using ANSI-C to manipulate the host program and Mitrion–C language. Mitrion–C offers efficient way to write code for parallel and pipelined architecture to preform edge detection. Then, the algorithm is tested on Intel Intanium 2 based architecture and compared its execution time with RC 100 platform based algorithm to check the speed up gain by FPGA based algorithm. The experimental results showed that the speed of the reconfigurable hardware FPGA based algorithm outperformed the software-based approach by more than 50 times.

Published: July 2020

Abstract
The solar wind nonradial velocity components observed beyond the Alfvén point are usually attributed to waves, the interaction of different streams, or other transient phenomena. However, Earth-orbiting spacecraft as well as monitors at L1 indicate systematic deviations of the wind velocity from the radial direction. Since these deviations are of the order of several degrees, the calibration of the instruments is often questioned. This paper investigates for the first time the evolution of nonradial components of the solar wind flow along the path from ≈0.17 to 10 au. A comparison of observations at 1 au with those closer to or farther from the Sun based on measurements of many spacecraft at different locations in the heliosphere (Parker Solar Probe, Helios 1 and 2, Wind, Advanced Composition Explorer, Spektr-R, Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun (ARTEMIS) probes, Mars Atmosphere and Volatile Evolution (MAVEN), Voyagers 1 and 2) shows that (i) the average values of nonradial components are not zero and vary in a systematic manner with the distance from the Sun and (ii) their values significantly depend on the solar wind radial velocity.
A Magnetar-asteroid Impact Model for FRB 200428 Associated with an X-Ray Burst from SGR 1935+2154
Authors: Dai Z. G. 
Published: July 2020

Abstract
Very recently, an extremely bright fast radio burst (FRB) 200428 with two submillisecond pulses was discovered coming from the direction of the Galactic magnetar SGR 1935+2154, and an X-ray burst (XRB) counterpart was detected simultaneously. These observations favor magnetar-based interior-driven models. In this Letter, we propose a different model for FRB 200428 associated with an XRB from SGR 1935+2154 in which a magnetar with high proper velocity encounters an asteroid of mass ∼1020 g. This infalling asteroid in the stellar gravitational field is first possibly disrupted tidally into a great number of fragments at a radius of ∼a few times 1010 cm, and then slowed around the Alfvén radius by an ultra-strong magnetic field, and in the meantime two major fragments of mass ∼1017 g that cross magnetic field lines produce two pulses of FRB 200428. The whole asteroid is eventually accreted onto the poles along magnetic field lines, impacting the stellar surface, creating a photon-e± pair fireball trapped initially in the stellar magnetosphere, and further leading to an XRB. We show that this gravitationally powered model can interpret all of the observed features self-consistently.

Published: July 2020

ABSTRACT
The application of phase change materials (PCMs) in building envelopes can help promote energy efficiency due to its high heat capacity. Our study aimed to provide energy and economic insights for deploying PCM to buildings in eight different regions of East Asia through a series of energy and economic analysis using computer modelling and simulations. The static payback period (SPP) and dynamic payback (DPP) methods were used to evaluate the economic feasibility of applying a PCM at different melting phase temperatures (20°C, 23°C, 25°C, 27°C and 29°C). Results show that the proper choice of a PCM melting temperature is a key factor to improve the performance of the PCM applied to buildings. A melting phase temperature of 29°C achieved the highest economic feasibility in Seoul, Tokyo; Pyongyang; Beijing; and Ulaanbaatar and a melting temperature of 23°C in Hong Kong had the highest economic feasibility. Overall, the combined economic and energy analysis presented in this study can play an important role in improving the energy and economic feasibility of PCM in buildings.
IMPROVING THE ENVIRONMENTAL PERFORMANCE OF FISH-FARMING HOUSES: A COMPARATIVE PASSIVE DESIGN STUDY IN SOUTH KOREA
Authors: Lee Kyu-In , Cho Yoon-Boum , Yi Hwang 
Published: July 2020

ABSTRACT
Aquaculture in South Korea largely involves crudely-built plastic fishery houses that consume excessive electricity and produce carbon emissions. This study explores a potential method to make Korean aquaculture more sustainable by suggesting design alternatives that can save energy and costs. To this end, the authors compare the energy use and indoor environments of three different designs through field mockups. The three designs include (i) a triple-layered plastic screen house (Design 1), (ii) an insulated vault house (Design 2), and (iii) a passive-house design (Design 3), in addition to (iv) a single-layered plastic house (baseline). Our findings indicate that, compared to the baseline, operational electricity was reduced to 57.81% in Design 1, 53.92 % in Design 2, and 40.59% in Design 3. Moreover, Designs 2 and 3 were able to mitigate indoor temperature fluctuations in winter. Design 1 showed a relatively unstable temperature distribution during the night but offered better farming conditions than the baseline. Humidity often rose to 100% but did not affect the maintenance of a desirable fish and workplace environment. Even a high concentration of carbon dioxide of up to 3,000 ppm in Designs 1 and 2 was not expected to harm farmers’ health. Cost analyses revealed that construction expenses increased to 20.9% in Design 1, 135.8% in Design 2, and 73.9% in Design 3 due to large quantities of materials and labor. Considering trade-offs with energy saving, the payback period is 7.2 years for Design 1, 35.5 years for Design 2, and 17.9 years for Design 3. Given that the lifetime expectancy of Designs 1 and 3 is over two years, the study’s results confirm that Designs 1 and 3 have a comparative advantage in producing sustainable fish-farming houses.
