    Abstract This paper reports on the development of an open-source image analysis software 'pipeline' dedicated to petrographic microscopy. Using conventional rock thin sections and images from a standard polarising microscope, the pipeline can classify minerals and subgrains into objects and obtain information about optic-axis orientation. Five metamorphic rocks were chosen to test and illustrate the method. Thin sections were imaged using reflected and cross- and plane-polarised transmitted light. Images were taken at different angles of the polariser and analyser (360° with 10° steps), both with and without the full-lambda plate. The resulting image stacks were analysed with a modular pipeline for optic-axis mapping (POAM). POAM consists of external and internal software packages that register, segment, classify, and interpret the visible light spectra using object-based image analysis (OBIAS). The mapped fields-of-view and grain orientation stereonets of interest are presented in the context of whole-slide images. Two innovations are reported. First, we used hierarchical tree region merging on blended multimodal images to classify individual grains of rock-forming minerals into objects. Second, we assembled a new optical mineralogy algorithm chain that identifies the mineral slow axis orientation. The c-axis orientation results were verified with scanning electron microscopy electron backscattered diffraction (SEM-EBSD) data. For quartz (uniaxial) in a granite mylonite the test yielded excellent correspondence of c-axis azimuth and good agreement for inclination. For orthorhombic orthopyroxene in a deformed garnet harzburgite, POAM produced acceptable results for slow axis azimuth. In addition, the method identified slight anisotropy in garnet that would not be appreciated by traditional microscopy. We propose that our method is ideally suited for two commonly performed tasks in mineralogy. First, for mineral grain classification of entire thin sections scans on blended images to provide automated modal abundance estimates and grain size distribution. Second, for prospective fields of view of interest, POAM can rapidly generate slow axis crystal orientation maps from multiangle image stacks on conventionally prepared thin sections for targeting detailed SEM-EBSD studies.

    Abstract Climate change might affect energy production and therefore the energy security of a country or region. This situation may impact renewable energy sources such as hydro power, leading to consequences on energy transition strategies. This might be critical in sensitive regions to climate change, one of them being the Caribe and northern South America. Since there are numerous energy systems based on sensitive technologies worldwide, it is necessary to introduce techniques to analyze the effects of climate change on different possible energy transition paths. The goal of this study is to develop and assess a method to analyze one of the most critical effects faced by climate change for societies worldwide: the sensitivity of the energy systems to climate change. This is especially critical in developing countries, in locations where temperatures will strongly increase in the following years. To assess this effect, this study proposes a vulnerability index (VI) to evaluate the vulnerability of an on-grid electricity system to climate change at the national and regional scales. This index was assessed using a Monte-Carlo method for uncertainty. The case of Colombia, a country with a system based on hydropower (> 70%) is used to illustrate the method. VI is based on variables related to climate change, the energy matrix, and vulnerability. Results show that the regions with the larger vulnerability correspond to the more energy-demanding ones. The VI for these regions is greater than 50% of the maximum possible vulnerability; meanwhile, the vulnerability of the whole country was estimated as 43%.

    Abstract Los teléfonos inteligentes, y sus aplicaciones, han transformado no solo la manera de comunicación, sino también cómo se viaja. Por ello, se analizó su papel actual en el sector turístico de Tena, Ecuador. Primero, se realizó una investigación exploratoria en la plataforma digital Google Play para identificar las aplicaciones de turismo existentes. Posteriormente, se encuestó a visitantes sobre su preferencia de uso de las aplicaciones en sus viajes. Finalmente, se entrevistó a 140 prestadores de servicios turísticos sobre el uso de aplicaciones. Se identificaron 150 aplicaciones, la mayoría (36) corresponden a Pichincha, y solo 4 aplicaciones a Tena. El visitante prefiere informarse a través de sitios web (67%), y utiliza redes sociales habitualmente (73%). El 39% han utilizado aplicaciones durante su visita, siendo Google Maps la más utilizada. Los prestadores de servicios utilizan redes sociales para promoción (57%), principalmente Facebook, pero el 69% desconocen o no utilizan aplicaciones de turismo.

    Abstract The jalapeño pepper is one of the best-known and most commonly consumed chili peppers in Mexico; its consumption is a tradition that dates to the first migrations of Europeans to the country. With time, its demand has increased, although in recent years its consumption presented a stabilization and stagnation. This work aimed to determine the preferences of Mexican consumers for jalapeño pepper, taking as a reference quality attributes and motivations that influence their purchasing and consumption habits, under the hypothesis that consumers in each region seek a certain type of jalapeño pepper based on specific quality attributes. In total, 1200 surveys were carried out in five regions of the country. The analysis of the information was performed using the ANOVA test, correspondence analysis, and multidimensional scaling. The main results of this study show that although there is a tendency towards frequent consumption, each purchase weighs less than 500 g. In the same way, the physical appearance of the product is fundamental at the time of purchase, in addition to other attributes such as flavor, color, and size, which are highly valued by consumers. Although there are similar consumption patterns, purchasing behaviors change by region, which can serve as a basis and spearhead for the development of differentiated strategies in the production and marketing of the product.
