Authors: Hernández-Morales Alejandro , Ávila-Padrón Francisco Javier , Carranza-Álvarez Candy , Maldonado-Miranda Juan José
Published: August 2020

Fractionated extraction of the leaves of Artemisia ludoviciana subsp. mexicana was performed, using hexane, dichloromethane and methanol, to obtain compounds of different polarity. Essential oils, aqueous decoction and hydroalcoholic extract were also obtained. Phytochemical profile was determined for each extract based on coloration and precipitation tests. Extracts were evaluated against three enterobacteria using the plate microdilution method. Chemical analysis revealed that dichloromethane fraction has a greater variety of compounds than hexane and methanolic fractions. The content of compounds of dichloromethane fraction correlates with the highest antimicrobial activity observed, suggesting that metabolites responsible for antimicrobial effect are intermediate polarity. Regarding extracts, ethanolic extract exerts a better effect than the decoction, while the essential oil shows the same antibacterial effect at low concentrations. Results demonstrate that A. ludoviciana subsp. mexicana has a great variety of compounds, which, according to their nature, can be eluted with solvents of different polarity. These compounds contribute to the antibacterial effect attributed to this plant.

Published: August 2020

In Mexico, bean crop is one of the most important agricultural resources to provide food also for its economic value as product. However, there is a lack of research related with Phaseolus vulgaris varieties, specifically for plants cultivated for human consumption as common bean pods. It was characterized the main phenological events and the biomass distribution in two different varieties “Black Valentine” (BV, green pod) y “Black Wax” (BW, yellow pod) of common bean. For each variety it was chosen 4 plants and every 10 days after planting (DAP) from each organ emerged the fresh and dry weight and the leaf area were recorded. Then, at 7, 14 , 21 , 28 and 35 days after anthesis (DAA) the growth, fresh and dry weight and nitrogen content were evaluated from pods (n=10) of each variety of common bean. During the first 30 DAP the dry weight accumulation in both varieties was correlated with leaf area. The beginning of flowering and fruit growth was an important factor in the source-sink relationship. Differences were not noted in the final fresh and dry weight of the pods between “BV” and “BW” varieties.

Published: August 2020

The microbiology of the rhizosphere has been investigated since 1904, revealing innumerable rhizomic microorganisms that promote growth in swamps (RPCPs), which have attracted a special interest to improve agroecological practices, crop productivity and protect soils from environmental contamination under a agricultural sustainability approach. This review addresses a topic as extensive as it is fascinating, beginning with the characteristics of soil microbiology. It also describes how RPCPs associated with plant roots offer greater crop growth through direct and indirect strategies. Also mention the complexity of plant growth and how it is done simultaneously through numerous metabolic activities. The bacterial genera of RPCP, the metabolic characteristics and the potential of entomopathogenic bacteria Bacillus thuringiensis (Bt) to be considered as RPCP are mentioned. Finally, the little known properties of Bt are exposed to benefit the growth of plants, their effectiveness in biocontrol of phytopathogens, as biofertilizers and / or biostimulants in crops. New perspectives are proposed to develop Bt products as a growth promoter in the near future. It is important to recognize that applied research of rhizosphere crops can be one of the key factors in achieving the sustainable yield of agriculture.

In recent years, the use of natural extracts has been an alternative in the control of pest insects in the search for a balance between the environment, production and the human being (Molina 2001). In the present work the objective was to conduct a study of the effectiveness of two aqueous extracts of the aromatic plants ruda and epazote as well as a combination of both for the control of white flies. The trial was done under a completely randomized experimental design with three treatments and ten laboratory repetitions. The tests were carried out on bean leaves infested with white flies and placed in Petri dishes covered with anti-aphids mesh, which were sprayed with undiluted extracts. Subsequently, a statistical analysis was carried out by means of an ANOVA and comparison test of means with the data thrown based on the number of dead flies. The study showed that the treatment developed by the combination of ruda and epazote extracts was the most effective. This study was carried out with the purpose of making contributions as an alternative for the natural control of bemisia tabaci.

Within the automotive industry one of the most used materials for user comfort is animal skin, this material is used to coat pieces that will have contact with the consumer. One of the most important problems that arise with the handling of the skin in operations of coating and assembly within plants of the automotive sector is the lack of resistance. A treatment that must be applied to the skin to improve its conditions of resistance to mechanical tension, is in function of two factors: percentage of moisture in the skin and amount of surfactant applied. In the present investigation, optimal operating conditions are established for the handling of the skin used in processes of the automotive sector based on a 3k factorial experimental design. The application case was carried out in a company dedicated to manufacture armrests for high-end cars. The results of the investigation show an improvement of 97% in operations where the resistance of the skin is required to meet the quality standards established in the automotive industry.

Published: August 2020

The main objective of this study is to develop a technique to evaluate the cognitive dispersion that exists in the contents and subjects of the curricula. The problem perceived by the authors is that learning is difficult when students have a greater diversity of subjects in their daily classes, when there are too many subjects per course or curricular axis and when they have fewer hours/class per day, which probably represents them greater cognitive complexity due to the dispersion of the contents to be learned. The experience of the authors in the design of the curricula has implied assessing the cognitive dispersion of multiple cases and the role of academic planners in systematically avoiding it. This research collects the methodology and experience of other studies in various areas and applies them in order to obtain a Cognitive Dispersion Index that allows us to evaluate this aspect when designing the study programs.

Published: August 2020

A material with phase change has the property of storing or releasing large amounts of energy in the form of latent heat, up to 100 times more than using sensible heat. In this paper we report the results obtained in the construction of a thermal energy storage system using erythritol as phase change material. The prototype uses 31.4 kg of erythritol with a melting point of 188°C and a latent heat of 340 kJ / kg, is heated up to 135°C and stores 17.17 MJ of energy in 9.8 hours with an efficiency of 48.66%. The system stored the energy for 2 days only considering the losses by the natural convection coefficient. To simulate the extraction of energy from the system, a forced convection coefficient of 3000 W/m2 K is considered in the heat exchanger and the system is discharged in 1 day. We can use 10.51 MJ daily in a period of 9.5 hours at a temperature of 135-118°C and the next day load it in a time 6 hours. The prototype was simulated with an accuracy of 91% compared to the real results.

Authors: Gómez-Puentes Francisco Javier , Reyes-López Jaime Alonso
Published: August 2020

The water quality of the Mexicali Valley aquifer was evaluated in order to estimate the geochemical processes involved with the increase of its salinity and the subsequent subsoil mineralization. The study area is located in the municipality of Mexicali, Baja California, Mexico in a section where the riparian corridor of the Colorado River converges with an agricultural area. The water of this river contains less than 1000 ppm of dissolved solids on average, but as the water is channeled and used in the crop’s irrigation, it undergoes a solute enrichment process until 2400 ppm in the upper aquifer. According to chemical analyzes the water salinization is mainly caused by sodium, sulfate and chlorine ions, while the geochemical modeling carried out with the PHREEQC program indicates that the processes related to calcite precipitation, dolomite and gypsum dissolution and water evaporation are primarily responsible for the water chemical evolution in the area.

TRANSMISSION CULTURELLE, FORMATION PROFESSIONNELLE ET ÉDUCATION DES ADULTES
Authors: Goudeaux Annie , Poizat Germain , Durand Marc
Published: August 2020

Les phénomènes transmissifs peuvent être considéréscomme des unités fondamentales d’activité, constitutives et constituantes de la socialité et de l’humanité. De sorte que toute anthropologie est une anthropologie de la transmission et que l’éducation comme pratique sociale, est un représentant majeur de ces unités anthropologiques d’activité humaine. Nous argumentons dans ce texte en faveur d’une approche praxéologique de la transmission culturelle qui allouerait la priorité au fait qu’elle concerne des actions ou des activités, et qu’elle est elle-même une activité. Nous détaillons trois aspects caractérisant cette approche : a) ce qui est transmis, que nous conceptualisons comme des constituants cognitivo-praxiques typicalisés d’une culture locale, b) les processus mimétiques impliqués dans la transmission, et c) les transformations de l’activité se produisant chez les héritiers conceptualisées en termes d’appropriation et d’individuation.

Published: August 2020

Introducción: La osteoporosis es una enfermedad que se incrementa conforme nuestra población envejece; esta se asocia a mayor riesgo de fracturas por fragilidad, conllevando a pérdida de la independencia, dolor crónico e incluso la muerte. Con el fin de evitar dichas complicaciones, es importante caracterizar la población con diagnóstico de fractura por fragilidad e identificar si se está realizando un adecuado tamizaje y abordaje del paciente con riesgo o diagnóstico de osteoporosis.

Materiales y métodos: Estudio prospectivo realizado en pacientes ingresados con fractura por fragilidad en un hospital de alta complejidad, en el periodo entre marzo-septiembre del 2018. Se realizó una caracterización según variables clínico-sociodemográficas y se aplicó criterios de tamización según diferentes guías a fin de determinar si se está realizando un adecuado tamizaje y abordaje del paciente con fractura por fragilidad.

Resultados: Se identificaron 70 pacientes con fracturas por fragilidad, la edad promedio fue de 80,01 ± 10,73 años. Se encontró que el 81,43% de los pacientes había sido evaluado por médico general pero tan solo el 50% había sido educado sobre prevención de caídas. Además, el 97,14%, 95,71% y 90,0% de los pacientes cumplían criterios de tamización para osteoporosis según las guías NOF, ISCD y OSC respectivamente y solo 11,43% habían sido tamizados.

Conclusión: Las fracturas por fragilidad son frecuentes en nuestro medio, sin embargo, los tiempos de atención e intervención son lentos y los esfuerzos en prevención tanto primaria como secundaria están siendo insuficientes.
Hemorragia alveolar por consumo de cocaína
Authors: Fajardo Javier , Neira Kristhel A.
Published: August 2020

La hemorragia pulmonar por inhalación de cocaína o alguno de sus derivados (crack-cocaina) resulta en un síndrome raro conocido como “pulmón de crack”, cuya presentación es aguda y potencialmente fatal. Del 25 al 60% de las personas que consumen cocaína reportan síntomas respiratorios después de la inhalación, pero menos del 5% consultan por esta causa. Los síntomas aparecen dentro de las primeras 5 horas luego del consumo y la presentación clínica puede ser variable con posibilidad de progresión. En los estudios radiograficos se pueden apreciar frecuentemente areas de afectación intersticial difusa de localización subpleural o peribronquial. El analisis del lavado broncoalveolar juega un papel importante en el diagnostico y exclusion de condiciones diferenciales. La presencia de hemosiderofagos en recuento significativo determina la hemorragia aveolar por inhalacion de cocaina. El diagnóstico y tratamiento oportuno es crucial en esta entidad. Se revisó un caso de hemorragia pulmonar por inhalación de crack – cocaina que resolvio satisfactoriamente.
Síndrome de Cushing exógeno de difícil diagnóstico
Authors: González Clavijo Angélica María , Fierro Maya Luis Felipe , Alvarez-Lozano Miguel Angel , Moreno-Soler Gonzalo Alejandro , Rodríguez-Paz Sebastián , Tarquino-Rincón Daniela
Published: August 2020

Introducción: el síndrome de Cushing (SC) es un grupo de signos y síntomas causados por la exposición crónica al exceso de glucocorticoides. El uso de fármacos con glucocorticoides es la causa más frecuente, pero algunos productos vendidos como suplementos nutricionales o medicamentos naturistas para el control de los dolores articulares pueden contenerlos de forma oculta, lo cual dificulta el enfoque diagnóstico.

Presentación del caso: paciente de 40 años con signos clínico típicos de síndrome de Cushing con resultados discordantes en las pruebas diagnósticas para identificar su origen. Finalmente se logra establecer que el paciente consumía de forma crónica un producto “naturista” conocido como Artrin®, el cual fue analizado en el laboratorio de la institución con resultados positivos para cortisol.

Conclusión: la exposición crónica a glucocorticoides exógenos, ya sea subrepticia, desconocida o prescrita, causa SC y debe distinguirse tempranamente de las formas endógenas para evitar la realización de pruebas diagnósticas y tratamientos inadecuados.

Published: August 2020

Introducción: la hidroxicloroquina se ha venido postulando en estos tiempos de pandemia como posible tratamiento eficaz frente a COVID-19. Esto ya que se ha demostrado por expertos chinos su capacidad para inhibir la replicación viral usando distintos mecanismos. En este momento es de vital importancia tener conocimiento acerca de las últimas investigaciones y ensayos clínicos en lo que respecta a un esquema de tratamiento efectivo que ayude a un mejor manejo de pacientes con infección por SARS-CoV-2.

Objetivo: presentar la información disponible sobre el uso de hidroxicloroquina como opción de manejo para pacientes infectados por SARS-CoV-2. Material y métodos: se realizó una revisión siguiendo el marco metodológico sugerido por Arksey y O’Malley. Las bases de datos utilizadas fueron: PubMed, MedLine, Lilacs, Scopus, Clinical Trials, Cochrane y CNKI. Se incluyeron únicamente textos en español e inglés, finalmente se realizó una caracterización y resumen de los estudios pertinentes para esta revisión.

Resultados: se incluyeron en la revisión 87 artículos académicos incluyendo estudios experimentales y no experimentales; todos con evidencia sobre el uso de hidroxicloroquina en COVID-19.

Conclusiones: A la fecha no hay información científica disponible que sustente y tenga la suficiente evidencia para soportar el uso de la hidroxicloroquina como tratamiento farmacológico en la pandemia actual. Dos ensayos clínicos aleatorizados se contradicen en cuanto a la efectividad de la hidroxicloroquina; sin embargo, ambos comparten errores metodológicos y tamaños de muestra limitados; y un único ensayo no aleatorizado con los mismos errores demuestra efectividad de la hidroxicloroquina. En cuanto al perfil de seguridad se cuenta con información que evidencia una menor tasa de efectos adversos de la hidroxicloroquina frente a la cloroquina por lo que se preferiría su uso en caso de demostrar efectividad frente a COVID-19. Existen varios ensayos clínicos aleatorizados en curso que se espera esclarezcan las dudas que surgen al revisar la literatura

A Wireless Collision Detection on Transmission Poles through IoT Technology
Authors: Dr. R. Dhaya  , Dr. R. Kanthavel
Published: August 2020

Transmission poles plays a major in the wired telecom communication as well as in the electrical transmission. The wireless communication receivers and antennas are also need poles for holding the antenna and several other peripheral units to its nearby. Most of the transmission poles are kept on the public places for providing a better communication signal and the electric supply. The road side transmission poles are extremely not protected with any safety devices. Those poles are standing on its own strength on the materials used for making the poles. Due to aging and several other factors there are chances for such poles to get damage very easily. Vehicle collision is an important factor in damaging the transmission poles kept near the road side. The proposed method is designed to identify the collision detection on the poles to alert the maintenance team to take immediate action against the faulty poles. It is achieved with the help of IoT technology connecting several peripheral units to a microcontroller.
Advisor as an Empowerer
Authors: Edlin Curtis , Yarwood Amelia
Published: August 2020

Advisors acknowledge that their words are powerful. On the one hand, they potentially influence a learner’s action if he or she is not confident enough to make his or her own decision. Thus, the degree of directiveness is a concern that they pay attention to in advising dialogues. On the other hand, advisors often encounter the situation where they play crucial roles in empowering learners to take a step forward to changing a critical situation, especially when he or she faces a difficulty. As the challenge involves not only academic matters but also interpersonal as well as emotional ones, they also take initiatives to create a “secure space” in their advising dialogues so that the learner feels accepted and comfortable sharing the core of his or her problem. The two stories below illustrate how advisors supported their learners in rather directive ways, which eventually ignited learners’ willingness to take charge of their own learning and overcome the challenging situation.
Advisor as a Significant Other
Authors: Imamura Yuri , Shelton-Strong Scott
Published: August 2020

While advisors take a neutral position in advising sessions, their particular positionality derived from their sociocultural background often–and naturally–encourages learners to openly share their stories. In those cases, advisors are positioned no longer as “advisors”. Rather, they become “insiders” of the learners’ lived experiences. Some of the stories become highly sensitive as the learners create a personal space based on the trusted relationship. It requires a great degree of responsibility to listen to their life stories, yet learning advisors appreciate the learners’ desire to share who they are. The two stories below describe how learning advisors play a role in their learner’s narratives as significant others, highlighting their shared backgrounds with their learners.
A Case Study of Learner Identity and Motivation in a Social Learning Space
Authors: Hooper Daniel
Published: August 2020

This case study represents one element within a larger ethnographic investigation into learner behaviors and identity within the English Lounge, a social learning space in the Self-Access Learning Center (SALC) at Kanda University of International Studies (Burke et al., 2018). Within this larger project, I interviewed Ryunosuke (pseudonym) twice as part of 30 semi-structured interviews conducted over a roughly one year period with 15 frequent users of the English Lounge. Stemming from an initial observation study of student behaviors in the English Lounge area, we were able to categorize regular users of the space into two distinct groups. The first was a core group of users who spent time at the English Lounge on a daily basis and appeared to be comfortable and ‘at home’ in the space. We also identified an active group of frequent users who would attend the Lounge just once or twice a week. We designated Ryunosuke as a member of the latter ‘frequent user’ group.
An Exploratory Case Study of English Speaking Anxiety Faced by Successful and Less Successful Japanese Learners
Authors: Nguyen-Xuan Hung
Published: August 2020

This article addresses the English speaking anxiety faced by successful and less successful Japanese learners of English. Two Japanese EFL students (one successful and one less successful) agreed to participate in the research. A survey and a semi-structured interview were used to gather the details of these two learners’ English learning experiences and frequency of dealing with English speaking anxiety. Results indicate that both learners felt speaking anxiety, but the less successful learner felt anxiety more frequently than the successful one. The successful learner also appeared to show high motivation and willingness to speak English, whereas the less successful one felt shy or tended to have fear of speaking English. The study is expected to provide some useful insights for further research of EFL students’ speaking anxiety.
Exploring Basic Psychological Needs in a Language Learning Center. Part 2: The Autonomy-Supportive Nature and Limitations of a SALC

Published: August 2020

Basic Psychological Needs Theory (BPNT) is one of several mini theories within Self-Determination Theory, a framework developed by Deci and Ryan’s (1985) to study human motivation. As part of a larger, on-going project, the three main components of BPNT, autonomy, relatedness and competence, are used as points of evaluation to determine the autonomy-supportiveness of a Japanese self-access learning center (SALC). Based on the analysis of 107 interviews, we will highlight how the SALC is structured to be an autonomy-supportive environment. Additionally, we will provide insight into the importance of relatedness to the learners of our SALC and explore the contractions between their desire to communicate in English and their reluctance to actualize their desires. Based on these findings, future interventions will be discussed to outline actions the SALC can take in order to further develop the autonomy-supportive nature of the self-access environment.
Shifting Roles in Continuous Advising Sessions

Published: August 2020

It is common for learning advisors to receive a request such as conversation practice or simple linguistic support in our institution simply because learners find them accessible and friendly. Although this may not be the usual role of a learning advisor, it can be the beginning of a long-lasting reflective dialogue. Learning advisors are aware that the learners’ initial interest is not necessarily an opportunity for reflection on their learning process. Nevertheless, they also acknowledge the fact that learner readiness for reflection varies depending on the learner. Thus, while advisors appear to be “conversation partners” at first, they endeavor to create reflective dialogues by incorporating advising strategies in each session. As the learning trajectory that the learner follows is not always straightforward, keeping an open mind and engaging in each advising session is crucial. The following stories depict the importance of openness to learners’ needs and maintaining continuous advising sessions in order to generate transformational learning.
DETERMINANTS OF TOURISM DEMAND IN INDONESIA: A PANEL DATA ANALYSIS

Published: August 2020

By 2014 Indonesia registered 11.6 million inbound foreign tourists, 135% higher than the year 2000. Since then, government policies to promote tourism flourished. This paper investigates the determinants of inbound tourism from the top nine mayor tourist origin countries into Indonesia covering the period of 2000 to 2014. This research employs a dynamic panel dataset to estimate the impact of per capita real income, relative prices, accommodation capacity, distance and public infrastructure investment on international tourism demand in Indonesia, capturing demand and supply-side effects. The results show that per capita income of tourist, relative price, and available rooms have a positive effect on tourism expenditure in Indonesia, while distance has a negative effect. Dummy variables capture large negative shocks in tourism arising from two terrorist attacks in 2002 and 2005, as well as from the global financial crisis in 2008. Income plays a positive but low impact on tourism demand compared to other nations. The positive effect of prices suggests an advantage of Indonesia in competitive tourism prices. Nevertheless, low prices also denote low value in tourism services. The substantial impact of accommodation may indicate that significant effects of tourism are allocated in lodging, minimizing the impact on other sectors.
