Autonomous pollination alleviates pollen limitation in the endemic Cienfuegosia yucatanensis Millsp. (Malvaceae)
Authors: Parra-Tabla Víctor , Alonso  
Published: January 2021

Background: Self-compatibility is common on endemic plant species, but pollen limitation and self-pollination could be risk factors.
Study species: The endemic Cienfuegosia yucatanensis (Malvaceae), whose distribution is mainly restricted to the north coast of the peninsula of Yucatán, México.
Questions: a) Are flowers of C. yucatanensis autonomous for pollination? b) Are C. yucatanensis fruit or seed-set limited by pollen deposition? and, c) Is there evidence of early inbreeding depression in C. yucatanensis ?
Study sites and dates: Two sites in the north of the peninsula of Yucatán in a seasonally dry scrubland, in the rainy season of 2013 and 2014.
Methods: Number of flowers and fruits were weekly recorded. Flowers were collected to count the number of conspecific pollen load and the number of pollen tubes. Autonomous pollination and pollen limitation were evaluated with a hand-pollination experiment. Inbreeding depression on fruit and seed production, and seed weight was evaluated.
Results: Flower and fruit production occur simultaneously and last from August to October. Conspecific pollen deposition on stigmas occurred through the whole flowering season and a maximum of pollen tubes was observed in August. Autonomous pollination treatment lead to similar fruit and seed production than cross-pollination, but open pollination produced significantly more seeds. No significant differences among self- and cross-pollination treatments on fruit and seed production or seed weight, were found.
Conclusions: Our results suggest that self-compatibility combined with a relatively efficient autonomous pollination, are suitable mechanisms for the reproductive assurance in C. yucatanensis , with no apparent effects of early inbreeding depression.
Description and distribution of Nemacystus howei (W.R. Taylor) Kylin (Chordariaceae) from the northern coast of the Yucatán peninsula
Authors: Ortegón-Aznar Ileana , Suárez Ana M. , Galindo-de Santiago María del Carmen , Wynne Michael J. 
Published: January 2021

Background: There are few studies about Nemacystus on the Atlantic coast, and N. howei has been reported only once for Mexico; that record, however, did not provide a description of this species.
Question: What are the morphological characteristics of Nemacystus howei and its distribution on the Yucatan coast?
Species study: Macroalgae, Phaeophyceae, Nemacystus howei.
Study site and year of study: North coast of Yucatán Peninsula of Mexico. Dry and rainy seasons from 2017 to 2019.
Methods: Sampling was carried out at five localities, at 5 and 10 m depths, with scuba equipment. Specimens were preserved in diluted formalin in sea water; silica gel and dried-pressed vouchers are housed at the UADY
Results: Six samples were collected at the five localities. Each one contains a small mass of filamentous of specimens of Nemacystus howei , that were found only during dry season, at both depths sampled. This alga has a thallus of an entangled filamentous mass of cylindrical, mucilaginous axes, of a light brown color. Younger branches have a solid central axis. Branching is abundant. The main, older axes are hollow. The assimilatory filaments are branched a few times, producing uniseriate colorless hairs and with plurilocular sporangia arising from the base. Nemacystus howei is easily confused with Cladosiphon occidentalis Kylin due to their similar morphology, branching pattern, and size.
Conclusion: The significant morphological similarities between these species as well as the paucity of specific works on the Phaeophyceae of the Yucatan Peninsula may explain why Nemacystus howei had not been previously reported.

Published: January 2021

Estudios numéricos del campo de flujo para toberas convergentes-divergentes con longitud de garganta han reportado fluctuaciones del flujo con ondas de choque oblicuo en la sección de la garganta, para la condición de flujo sobreexpandido. Sin embargo, para otras condiciones del flujo, para un mismo tipo de tobera, el conocimiento es limitado. En el presente trabajo, el objetivo es determinar el comportamiento del flujo en la longitud de garganta y en la divergente, para una tobera cónica experimental clasificada como Helios-X, para la condición de flujo subexpandido. Se realizaron simulaciones numéricas 2D del campo de flujo con el código ANSYS-Fluent versión 12.1, aplicando el modelo RANS. Se emplearon las ecuaciones gobernantes para el flujo compresible, conservación de la masa, cantidad de movimiento, energía y de estado; así como, para la turbulencia el modelo SST de Menter y para la viscosidad en función de la temperatura la ecuación de Sutherland. En la sección de la garganta, adyacente a la pared, el flujo presentó fluctuaciones, en la simetría axial el flujo presentó una aceleración escalonada; en la sección divergente, el flujo se desaceleró en cierta región, sin embargo, el flujo salió de la tobera a velocidad supersónica ligeramente mayor de Mach 3. Se concluye que en la sección de la longitud de garganta se presenta un patrón de flujo, así como, en la sección divergente.
La interdisciplinariedad pedagógica en la asignatura la Expresión Plástica y su Didáctica en Primaria, desde un enfoque artográfico
Authors: Méndez Suárez María 
Published: January 2021

En este informe de investigación a/r/tográfico se pretende mostrar y demostrar la importancia de la asignatura ‘La Expresión Plástica y su Didáctica en Primaria’, en el aprendizaje holístico del alumnado y en la construcción de nuevos enfoques pedagógicos y adquisición de competencias, a través de actividades interdisciplinares y grupales que van más allá de la mera manipulación de materiales y aprendizaje de técnicas pictóricas. El profesor, en este caso, sirve de orientador y son las alumnas y los alumnos los que toman sus propias decisiones para construir la actividad de una manera personal y autónoma. Mediante conceptos tales como ‘Educación Artística’, ‘espacio’, ‘cuerpo’, ‘mensajes’, etc., y el visionado de imágenes de teatro, se insta al alumnado del Grado de Educación Primaria de la Facultad de Educación de la Universidad de Extremadura a crear mensajes visuales a través de la fotografía de sus cuerpos, formando diversas letras, que, posteriormente, tienen que organizar y ordenar para construir una frase corta que aborde algún contenido transversal en otro idioma, yendo, de esta manera, más allá de los contenidos curriculares.

Architectural Interventions to Mitigate Occupational Stress Among Office Workers
Authors: Norouzianpour Hirbod 
Published: January 2021

Stress is one issue that affects the health and well-being of every building occupant. The negative effects of stress are more pronounced in workplaces, where stress can act as a major agent of disease and an impediment to employee productivity and satisfaction. The underlying causes of occupational stress are varied and include job insecurity, extended hours, excessive workload, altercations within the organization, tight deadlines, changes in responsibilities, and lack of autonomy, among others. One of the factors that can contribute to overall occupational stress is the working environment itself—a factor that can be mitigated by design. While occupational stress may arise from a multiplicity of causes, designers have numerous interventions they can employ to decrease it.
The literature on occupational health, well-being, satisfaction, and productivity is broad and multifaceted; however, this paper is limited to exploring stress factors that correlate with the built environment and focuses on employees who are experiencing a high rate of stress in office buildings as the target group. To address these issues, supporting literature was explored to identify environmental interventions that could reduce stress or enhance the stress-coping abilities of workers in offices by improving the environmental quality of the built environment.
This article explores the following questions: How does space cause people to experience mental stress? In what ways can the built environment itself be a generator of stress? What are the main environmental factors in offices that can mitigate the stress levels of employees or help them to recover more easily from work-related stress? To answer these questions, it is necessary to understand the causes and mechanisms of chronic stress, including work-related stressors, and to identify the factors in the built environment that can be associated with occupational stress. The present paper is based on concurrent analyses of supporting literature in the rather different fields of architecture, public health, psychology, management, and environmental studies. The outcome is an identified set of practical strategies that provide solutions for healthier and more productive workplaces. By concentrating on measures that can reduce employee stress levels, these strategies can be used as a source for evidence-based workplace designs.

<p class="abstract">Post-inflammatory hyperpigmentation (PIH) is a multifactorial disorder linked to alterations in melanin pigment because of inflammatory skin condition or any injury. Acne-induced PIH is one of the common presentations observed in dermatological consultations in India, especially in females of younger age group. A wide range of topical depigmenting agents are available for effective clearance of hyperpigmentation in patients affected with acne. Besides, chemical peels and cosmetic procedures like lasers and light therapies are commonly employed. However, treatment of acne-induced PIH is challenging in Indian clinical settings for multiple reasons such as relapsing of the condition and long-standing nature of the disease; the tendency of treatment to cause pigmentation; insufficient clinical data on natural ingredients; and lack of clinical practice guidelines, exclusively for the management of PIH in Indian patients. An experts’ panel discussion involving dermatologists all over India was conducted to review the evidence-based concept of acne-induced hyperpigmentation, and to obtain expert opinions on effective and practical management of acne-induced PIH in Indian settings. This article outlines consensus expert opinions aimed at identifying, diagnosing, and managing acne-induced PIH using topical depigmenting agents in Indian patients. It also highlights effective preventive strategies, the role of patient counselling and education regarding awareness about the disease and its treatment strategies. </p>

The modified logistic regression (Morais-rodrigues et al., 2020) was used to classify breast cancer subtypes using all microarray database samples. A stabilizing term, that allows the assignment of values to αi∗ parameters, was inserted in this methodology and with that, during the derivation there is the insertion of the identity matrix (positive defined) which added to the other semi-defined part, results in a positive defined matrix, which has auto values > 0 and determinant > 0, square matrix is full rank if it is reversible (determinant > 0) , which results in a single solution. In the results it was observed that some genes were located topologically in the extremities after plotting the parameters αi∗, these parameters are related to the expression of genes with a suppressor or oncogenic profile in breast cancer, and with genes not studied yet. Some of these genes were found in gene regulatory networks from the search of Iglesias-Martinez et al. (2016), and S-score values were associated with these genes, negative value S-score is indicative of tumor suppressing or reduced gene activity and the positive value S-score is indicative of oncogene or increased gene activity (de Souza et al., 2014). In view of the importance of these genes, this article provides a literary review of them.
