Aspectos de la fisiología y el cultivo del lulo (Solanum quitoense LAM.) en Colombia: una revisión
Authors: Alvarez Herrera Javier Giovanni , Jaime Guerrero Marilcen , Fischer Gerhard 
Published: January 2022

Contextualización: el lulo es un fruto promisorio de alta demanda en los mercados, debido a sus excelentes propiedades organolépticas, además de ser fuente importante de vitaminas y minerales.

Vacío de conocimiento: en los últimos diez años se han desarrollado múltiples investigaciones sobre la ecofisiología de la planta de lulo, sin que exista una revisión de literatura de este.

Propósito del estudio: recopilar aspectos generales del cultivo, incluyendo los principales requerimientos agronómicos y aspectos ecofisiológicos para una producción sustentable.

Metodología: la investigación se basó en una revisión metódica y ordenada de los estudios más relevantes publicados en diferentes bases de datos.

Resultados y conclusiones: el cultivo de lulo se cultiva entre los 1900 y 2200 msnm en Colombia, con temperaturas de 15 a 24 °C. Requiere entre 1.500 a 2.500 mm de precipitación al año. Se asemeja a una planta de días cortos, que exhibe su mejor desarrollo en sitios sombreados con humedades relativas cercanas al 80 %. El método más eficiente de polinización es el realizado por abejorros (Bombus terrestris y Bombus sp.) por medio de vibraciones. La fotosíntesis neta del cultivo de lulo varia de 5,52 a 34,03 μmol CO2 m-2 s-1 a los 398 y 460 días después de transplante; mientras que la eficiencia máxima del fotosistema II (Fv/Fm) en el cultivo oscila entre 0,55 y 0,65, para plantas sin y con aplicación de nitrógeno foliar.

Los valores de clorofila (a, b y total) para plantas de lulo son mayores en plantas en etapa de trasplante que en producción, debido a la reducida área fotosintética. Las concentraciones de nitrógeno mayores a 110 mg L-1 generan mejor rendimiento y mayor área foliar. La planta de lulo comienza la producción entre los ocho y 12 meses después ser trasplantada y produce rendimientos promedio de 8,5 t ha-1. El desarrollo y crecimiento de los frutos de lulo tiene un comportamiento que se ajusta a un modelo logístico sigmoide simple. Los frutos de lulo en la cosecha pueden llegar a alcanzar hasta 209 g con una firmeza de 58 N y valores de 13.6 °Brix y 56,2, 10,8 y 46,8 para los parámetros de color luminosidad (L*), cromaticidad a* y cromaticidad b*, respectivamente.
Human Versus Machine: A Comparison of Robo-Analyst and Traditional Research Analyst Investment Recommendations
Authors: Coleman Braiden , Merkley Kenneth , Pacelli Joseph 
Published: January 2022

ABSTRACT
We provide the first comprehensive analysis of the properties of investment recommendations generated by “Robo-Analysts,” which are human analyst-assisted computer programs conducting automated research analysis. Our results indicate that Robo-Analyst recommendations differ from those produced by traditional “human” research analysts across several important dimensions. First, Robo-Analysts produce a more balanced distribution of buy, hold, and sell recommendations than do human analysts and are less likely to recommend “glamour” stocks and firms with prospective investment banking business. Second, automation allows Robo-Analysts to revise their recommendations more frequently than human analysts and incorporate information from complex periodic filings. Third, while Robo-Analysts' recommendations exhibit weak short-window return reactions, they have long-term investment value. Specifically, portfolios formed based on the buy recommendations of Robo-Analysts significantly outperform those of human analysts. Overall, our results suggest that automation in the sell-side research industry can benefit investors.

Published: January 2022

Objetivo: Determinar la prevalencia de sobrepeso-obesidad y su relación con el nivel de adherencia a la dieta mediterránea en estudiantes de Medicina de la Universidad Central del Ecuador en el periodo lectivo 2019-2020.
Metodología: Diseño epidemiológico analítico transversal en una población de 2730 estudiantes que acuden con regularidad a clases en la Universidad Central del Ecuador en el período 2019–2020, con una muestra de 287 estudiantes seleccionadas aleatoriamente. Se evaluó el nivel de adherencia a la dieta mediterránea mediante la encuesta KIDMED. Para medir el nivel de actividad física y estado nutricional se utilizó el cuestionario IPAQ de la OMS y el IMC (kg/m2) respectivamente.
Resultados: Del total de alumnos encuestados el 79.1% (n=227) IC95%: 74.36-84.83, presentan un nivel de adherencia medio-bajo a la dieta mediterránea. El 20.9% (n=60) IC95%: 16.17-25.64, presentan sobrepeso o algún grado de obesidad. Y el 38% (n=110) IC95%: 32.67-43.99, son inactivos. No existe relación entre nivel de adherencia a la dieta mediterránea e índice de masa corporal (p=0.381), ni entre nivel de actividad física e índice de masa corporal (p=0.764). Sin embargo, se encontró una relación entre tipo de vivienda o residencia y nivel de adherencia a la dieta mediterránea (p=0.001).
Conclusiones: El estudio demuestra que no existe relación entre el nivel de adherencia a la dieta mediterránea y el índice de masa corporal referente a sobrepeso-obesidad, aunque no descarta déficits nutricionales; sin embargo, se evidencia relación con el tipo de residencia donde demuestra que los hábitos alimenticios pueden estar condicionados al ambiente familiar.

******************************
The problem of the status of being a single parent who experiences a change in role and has a double burden in the formation of a child’s gender identity, becomes a separate difficulty for single parents. The formation of gender identity itself is an important part of recognizing the concept of gender as a boy (masculine) or female (feminine) which is influenced by biological, social and cognitive factors during the socialization process of their parents. To describe this situation, this research study focuses on examining how gender relations between children and single parents of different sexes provide an understanding of children’s gender identity using social learning theory. In this study, a qualitative approach was used based on a critical review of the literature, both theoretical and empirical. The results showed that, the process of forming a gender identity in the socialization stage was considered to be an imbalance in the social learning process of gender identity. The domination of gender norms when the socialization of gender identity formation obscures the role of one gender, so that the meaning of gender is considered biased. The results showed that in single parent families, there tends to be an imbalance in the social learning process of gender identity because of the vacuum of gender roles. The domination of gender norms during the socialization of gender identity formation can obscure the role of one gender, so that the meaning of gender is considered biased.

It is aligned with the regent of Sambas vision that has been determined in RPJMD 2016-2021 (the government masterplan). For example, building the life quality of religious community, providing hajj service facilites, providing religious consultancy, empowering houses of Quran in the districts, conducting preach during Ramadan, reciting on Magrib (dusk time), and visiting people’s house programme. There are also another program such as young preachers recruitment, non-civil servant consultant, and empowering people and religious teachers to preserve the community post conflict in the places where the social religious problems threaten the community.
MAPPAJA’ PRACTICES IN AGRICULTURAL COMMODITY TRADING IN THE DISTRICT OF WEST SINJAI, SINJAI REGENCY
Authors: Ermiati Ermiati , Wahab Abdul , Haddade Abdul Wahid 
Published: January 2022

This study will elaborate on the form of mappaja' trading, which is considered as an attractive economic issue as in its transactions, people do not use a system of weighing scales in trading their harvests, but with a cost estimation system for the goods. Therefore, in the trading practice, there is often a discrepancy between the harvest and the buyer’s expectation, because it may contain an element of gharar/obscurity of the goods, which can lead to an invalid transaction and harm one of the parties. This study indicated that the practice of mappaja' for agricultural commodities has occurred for a long time. The mechanism is by estimating the number of plants based on mutual trust and responsibility. The agricultural commodities used as the mappaja' objects are cloves and vegetables (carrots, cabbage, and tomatoes). The payment method in mappaja' practice is carried out in two ways, namely full payment and twice payment. Twice payment refers to the transaction where half of the payment was handed over on the agreement as a down payment and a sign of completion, then the rest of the payment were handed after the harvest. The condition of the plant is ready to harvest or not ready for harvest in the transaction of mappaja’. The rights and obligations of both parties are that traders are obliged to make payments to farmers according to the agreement and for the farmers, they have to keep taking good care of the plants if at the time of the transaction the condition of the plants is still not ready for harvest.

The variations of hydrophilic self-cleaning properties and refractive index dependence in the ZrO2 thin films by Gamma Irradiation
Authors: Abayli D. , Baydogan Nilgün 
Published: January 2022

ZrO2 thin film samples were produced by the sol-gel dip coating method. Four different absorbed dose levels (such as ~ 0.4, 0.7, 1.2 and 2.7 Gray-Gy) were applied to ZrO2 thin films. Hence, the absorbed dose of ZrO2 thin film was examined as physical dose quantity representing the mean energy imparted to the thin film per unit mass by gamma radiation. Modification of the grain size was performed sensitively by the application of the absorbed dose to the ZrO2 thin film. Therefore the grain size reached from ~50 nm to 87 nm at the irradiated ZrO2 thin film. The relationship of the grain size, the contact angle, and the refractive index of the irradiated ZrO2 thin film was investigated as being an important technical concern. The irradiation process was performed in a hot cell by using a certified solid gamma ray source with 0.018021 Ci as an alternative technique to minimize the utilization of extra toxicological chemical solution. Antireflection and hydrophilic properties of the irradiated ZrO2 thin film were slightly improved by the modification of the grain size. The details on the optical and structural properties of the ZrO2 thin film were examined to obtain the optimum high refractive index, self-cleaning and anti-reflective properties.
Synthesis and characterization of electrically conductive silicone rubber — TiB2 composites
Authors: Joshi Aparna M , Athawale Anjali A 
Published: January 2022

In this paper, electrically conductive composites comprised of silicone rubber and titanium diboride (TiB2) were synthesized by conventional mixing methods. Fine particles of TiB2 (in micron size) and 10 parts per hundred parts of rubber (phr) proportion of carbon black (XC-72) were used to make the composites with HTV silicone rubber. The composites were cured at appropriate temperature and pressure and the effect on the electrical properties was studied. The resistance of the silicone rubber is ~ 1015Ω which decreases to 1–2 kΩ in case of composites with negligible effect of heat ageing. The hardness increases by ~ 35% simultaneous to the decrease of ~ 47% in the tensile strength. Morphological characterization indicates the homogeneous dispersion of the fillers in the composite.
Interaction of light with lead halide perovskites: A review
Authors: Dang Zhiya , Dinh Duc Anh 
Published: January 2022

Lead halide perovskites are the new rising generation of semiconductor materials due to their unique optical and electrical properties. The investigation of the interaction of halide perovskites and light is a key issue not only for understanding their photophysics but also for practical applications. Hence, tremendous efforts have been devoted to this topic and brunch into two: (i) decomposition of the halide perovskites thin films under light illumination; and (ii) influence of light soaking on their photoluminescence (PL) properties. In this review, we for the first time thoroughly compare the illumination conditions and the sample environment to correlate the PL changes and decomposition of perovskite under light illumination. In the case of vacuum and dry nitrogen, PL of the halide perovskite (MAPbI3–xClx, MAPbBr3–xClx, MAPbI3) thin films decreases due to the defects induced by light illumination, and under high excitations, the thin film even decomposes. In the presence of oxygen or moisture, light induces the PL enhancement of halide perovskite (MAPbI3) thin films at low light illumination, while increasing the excitation, which causes the PL to quench and perovskite thin film to decompose. In the case of mixed halide perovskite ((MA)Pb(BrxI1-x)3) light induces reversible segregation of Br domains and I domains.

Published: January 2022

Abstract
The work presents the results of research on the structure of welded joints in the area of heat affected zone (HAZ). Based on precisely performed metallographic tests, the contribution of individual structural components in the area of welds of pipes welded with the induction method was assessed. The volume fraction of individual structural components in various areas of the heat affected zone, the size of the grain formed in the welding process, as well as its shape coefficients were determined. On the basis of metallographic observations, an attempt was made to describe the course of the pressure induction welding process, taking into account the structural changes, phase changes and the recovering and recrystallization processes taking place in this process.
