Introducción: Las poblaciones del coral Orbicella annularis han mostrado bajo reclutamiento en el Caribe. Uno de los cuellos de botella demográficos es la alta mortalidad en las primeras etapas de desarrollo. El conocimiento detallado del ciclo y las tasas de supervivencia de estas fases nos permitirá ayudar en la recuperación de la población y la restauración de los arrecifes.
Objetivo: Describir la embriogénesis y estadios larvarios obtenidos por fertilización asistida y medir las tasas de asentamiento y supervivencia de las larvas en sustratos artificiales, antes de ser trasplantadas al arrecife.
Métodos: Seis días después de la luna llena de septiembre de 2021, se recolectaron bolsas de gametos de ocho colonias de O. annularis en el Parque Nacional Natural Los Corales del Rosario y San Bernardo, Colombia, y se llevaron al laboratorio. Se realizó fecundación cruzada, se siguió el desarrollo embrionario y larvario hasta el asentamiento larval y se registró supervivencia hasta el día 41. Las larvas se mantuvieron en tres tanques con agua de mar filtrada con 126 sustratos marcados, previamente acondicionados con algas coralináceas costrosas. Luego, los sustratos se trasplantaron al arrecife.
Resultados: El inicio del desarrollo embrionario ocurrió 1.11 hAF (horas después de la fertilización), cuando las células mostraron signos de la primera división, y duró hasta 104.59 hAF cuando comenzaron a metamorfosearse. El asentamiento de larvas se observó al sexto día AF. Veintiún días después de la fecundación se encontraron zooxantelas. La supervivencia de las larvas después del asentamiento fue de 27.5 %.
Conclusión: En este primer esfuerzo de propagación sexual utilizando O. annularis en Colombia, 1.4 % de larvas competentes completaron todo el proceso de desarrollo. Aunque la tasa de supervivencia fue baja, estos resultados se suman a los esfuerzos de restauración de corales en el Caribe en los que se ayuda a las especies a aumentar la supervivencia de los corales en sus primeras etapas de desarrollo.
«Ilaciones de aquella edad». Santa María de Huerta: una lectura de la identidad nobiliaria del VII duque de Medinaceli don Antonio Juan Luis de la Cerda desde la cronémica social
Authors: Romero-Medina Raúl 
Published: May 2023

Este ensayo aborda una reflexión cronémica y social sobre la identidad nobiliaria de don Antonio Juan Luis de la Cerda (1607-1671), VII duque de Medinaceli. Sus ideas artísticas para la capilla mayor del monasterio de Santa María de Huerta son el reflejo de un proyecto político que reivindicaba su antiguo derecho al trono real. Para pergeñarlo hizo uso de la figura del arzobispo Rodrigo Jiménez de Rada, allí sepultado, y del monarca que lo fundó, Alfonso VIII de Castilla, abuelo materno de Fernando III, el padre de Alfonso X «el Sabio», de cuyo hijo primogénito, Fernando de Castilla, descenderían los infantes que dieron origen a la Casa ducal de Medinaceli. En este proyecto tuvo un destacadísimo papel su madre y tutora, Antonia de Toledo y Colonna, quien utilizó la representación genealógica como emblema catalizador y la causa de canonización del rey Alfonso VIII para reivindicar una legitimación a lo divino.

Damping-off caused by Pythium aphanidermatum (Pa) is one of the most destructive diseases for watemelon seedlings. Application of biological control agents against Pa has attracted attention of many researchers for a long time. In this study, an actinomycete isolate JKTJ-3 with strong and broad-spectrum antifungal effect was screened from 23 bacterial isolates. Based on the morphological, cultural, physiological, and biochemical characteristics as well as the feature of 16S rDNA sequence, isolate JKTJ-3 was identified as Streptomyces murinus. We compared the biocontrol efficacy of isolate JKTJ-3 and its metabolites. The results revealed that seed and substrate treatments with the JKTJ-3 cultures showed a significant inhibitory effect on watermelon damping-off disease. Seed treatment with the JKTJ-3 cultural filtrates (CF) had higher control efficacy that of the fermentation cultures (FC). Treatment of the seeding substrate with the wheat grain cultures (WGC) of JKTJ-3 exhibited better control efficacy than that of the seeding substrate with the JKTJ-3 CF. Moreover, the JKTJ-3 WGC showed the preventive effect on suppression of the disease, and the efficacy increased with increase in the inoculation interval between the WGC and Pa. Production of the antifungal metabolite actinomycin D by isolate JKTJ-3 and cell wall-degrading enzymmes such as β-1,3-glucanase and chitosanase was probably the mechanisms for effective control of watermelon damping-off. It was showed for the first time that S. murinus can produce anti-oomycete substances including chitinase and actinomycin D. This is the first report about S. murinus used as biocontrol agent against watermelon Pa-induced damping-off.

Published: May 2023

The main goal of the study is to assess the Decision criteria, and the determining factor for the sustainability of entrepreneurial startups in order to contribute towards social inclusion and capacity building. Both concepts are in the development phase and are the outcome of entrepreneurial ecosystem and individual behavior and traits. The current study observed the research problem as entrepreneurship and the entrepreneurial startups are the continuous phenomena required for every economy. The lack of an efficient ecosystem and incompetent trait of an entrepreneur drags the entrepreneurial startup to a failure. Therefore, an assessment on decision criteria and determining factors categorizing them with their importance may provide requisites to lead a successful entrepreneurial startup contributing to the social inclusion and capacity building. The study solved the research problem by statistical assessment of decision criteria and determining factors and categorizing them with their importance may provide requisites to lead a successful entrepreneurial startup. The research is built on research questions, objectives, conceptual model, and hypothesis which are tested based on the data collected. The collection of data was done through a survey questionnaire on a sample of established entrepreneurs. The study concludes that five components of decision criteria are Region, Competition, Funding Opportunities, Tax System, and Country Economic Situation, whereas the eight components Consciousness and Reliable, Pursuit Results, Flexibility, Stress Resistance, Skills Identification Exploitation Potential Market Opportunities, Leadership, Creativity and Innovation, and Delegation Decision Making of determining factor are required for a successful entrepreneurial startup to be able to work towards social inclusion and capacity building.

Abstract
Rockfall hazards frequently occur along national road G318 in west Hubei, China. To better understand the distribution and potential for hazards along road G318, we combined the results of a 3-year engineering geological investigation, statistical modeling, and kinematics-based method in this study to identify high-risk road sections. Two types of rockfall sources were considered in the case of road cut slopes and natural cliff slopes. Rockfall source area cells were preliminarily identified via slope angle threshold (SAT) analysis, which is based on the slope angle distribution (SAD) method, and then improved via the machine learning model, considering rockfall controlling factors. The temporal and size probabilities of source areas were separately calculated via the Poisson distribution and power-law distribution theory. To obtain the runout probabilities and potential influence areas of release sources, rockfall trajectory simulation was performed with the Flow-R tool. In this process, the reach angle was determined through back analysis and then validated against field investigation data. The rockfall hazard probability was finally calculated by integrating the spatial, temporal, size, and runout probabilities of rockfall sources. The results indicated that the potential source area grids decreased from 160,823 to 4,002 units with only a 34.2% loss of historical rockfall samples. The simulation efficiency increased approximately 40 times, which highly reduced the trajectory simulation burden. The rockfall trajectory simulation results matched the field measurements well, with an approximately 96% accuracy. Under 5-, 20-, and 50-year return period scenarios, potential high-risk road sections were found at two size levels (larger than 1 000 m3 and 10 000 m3). This research could help the local government to better understand rockfalls from source area existence and potential risks to roads.
Evidence-Based Policy Making: Analysis and Policy Recommendations for how the Philippines can manage a Cost-Effective Clean Energy Transition.

Published: May 2023

Abstract
The purpose of this research was to assess different scenarios for a cost-effective clean energy transition in the Philippines. This was done by using the Open Source Energy Modelling System (OSeMOSYS), which is a modelling software that can be used to project future energy capacities for a country, among other relevant factors such as capital investment and carbon emissions. The six scenarios modelled were least cost (LC), coal phase out (CPO), Philippines energy plan (PEP), combined energy plan (CEP), nationally determined contribution (NDC) and net zero (NZ). The key findings indicated that the CEP scenario was the most cost-effective scenario as the emissions are over 50% less compared to the LC scenario, as well as phasing out coal by 2050 and supporting the goals of the Philippines Development Plan. However, the ambitious NDC and NZ scenarios should be worked towards if funding can be secured to support them. For the Philippines, the main focus must be on the phasing out of coal, as well as a particular focus on certain renewables and the importance of finance, among other factors. This study therefore presents a discussion based on the results about the most crucial factors and what can be done to make an energy transition successful.
