System of data recollection, analysis and transfer by NFC for transport systems

This paper shows the development and test of a prototype that collects and analyzes data of cycling trips, such as position, distance, speed, and travel time. This device was made to provide an extra security layer to the data transfer in embedded systems. The raw information that is produced by the project described in this paper is highly valued, so there is a need to record and transfer data in a secure way between electronic devices. The solution proposed in this project was based on the Near Field Communication (NFC) protocol to make the communication stage from an Electronic Control Unit to NFC tags, and then, the information stored in the tags can be read from smartphones that have an NFC module inside them. The data was generated from a Global Position System (GPS) module and antenna using the Haversine formula to calculate the distance between two geographical points, this considering the earth as a sphere to minimize the error produced taking the earth as a plane surface. A functional device that includes extra security of the data transfer in cycling trips, through NFC technology was successfully developed, however, future implementations can be extrapolated to other areas, such as the transportation sector

Kwapa: Gente del río. Estrategias transmedia de impacto social

El PAP Alter Código, período Primavera 2023, trabajó con los dos proyectos que se han venido trabajando en semestres anteriores: el videojuego A Orillas del río y el documental Déjennos pescar. Ambos proyectos parten de la metodología interdisciplinaria y colaborativa con miembros de la comunidad Cucapá para crear representaciones audiovisuales no estigmatizantes, que detonen el sentido de comunidad y refuercen su acervo cultural. El videojuego A Orillas del río es del género point and click, de vista isométrica, el cual está inspirado en el cuento oral tradicional El zorro y el coyote, que busca ser una herramienta lúdica de aprendizaje para reforzar el aprendizaje de la lengua Cucapá en los niños. Los resultados obtenidos fueron el demo del nivel uno (escenas uno y dos); colorimetría, arcos de personajes principales; programación de minijuegos. Dentro del documental ‘Déjennos pescar’ los resultados fueron un montaje, una clasificación del material grabado con transcripciones de audio, mientras que en la parte de estrategia de impacto se creó un manual de uso de redes sociales con colorimetría, tipografía, estilo de voz, tipo de contenido según la red social, para los futuros integrantes del equipo.ITESO, A.C

Investigación de mercados y desarrollo web para la marca Seasons México, Love Your Skin

La marca de skincare desea registrar el aroma característico de su producto estrella, para lo cual se necesita un estudio de mercado que avale la relación entre la marca y el aroma, por lo cual este reporte aborda la investigación que se realizó para confirmar o descartar la asociación de aroma, la cual abarcó una primera etapa en investigación de neuromarketing donde por medio de un aparato se detecta el enfoque de la vista en algún punto fijo (eyetracking) el aroma se colocó en el ambiente con la hipótesis de que los participantes al olor el aroma del producto estrella enfocaran su vista en el logo de Seasons. Como segunda etapa a investigación cubre una encuesta a nivel nacional donde se les pregunta a los participantes el aroma con el que asocian a la marca Seasons. Como segundo objetivo, se encuentra determinar la viabilidad de un nuevo producto, este es un bloqueador con color, por lo que se hizo una investigación de mercado por medio de encuestas para conocer los gustos, preferencias, hábitos e influencias que hay en el mercado. Por otra parte, se trabajó en el diseño de una posible Página Web de Seasons, dirigida específicamente al sector de clientes distribuidores. Se realizó una investigación sobre la posibilidad de utilizar Mercadoshop como opción principal debido a su bajo coste en relación con las comisiones por transacción, con base en esta premisa se propusieron varios módulos o apartados que resultan atractivos para ese tipo de consumidor dentro de la misma página web, posteriormente se encontró que mercadoshop tiene una limitante en cuanto al diseño de ciertos módulos o funciones en su plataforma por lo que se consideró utilizar Shopify, siendo esta una plataforma más abierta con más posibilidad de diseño.ITESO, A.C

Adaptive genetic diversity and evidence of population genetic structure in the endangered Sierra Madre Sparrow (Xenospiza baileyi).

The magnitude and distribution of genetic diversity through space and time can provide useful information relating to evolutionary potential and conservation status in threatened species. In assessing genetic diversity in species that are of conservation concern, several studies have focused on the use of Toll-like receptors (TLRs). TLRs are innate immune genes related to pathogen resistance, and polymorphisms may reflect not only levels of functional diversity, but may also be used to assess genetic diversity within and among populations. Here, we combined four potentially adaptive markers (TLRs) with one mitochondrial (COI) marker to evaluate genetic variation in the endangered Sierra Madre Sparrow (Xenospiza baileyi). This species offers an ideal model to investigate population and evolutionary genetic processes that may be occurring in a habitat restricted endangered species with disjunct populations (Mexico City and Durango), the census sizes of which differ by an order of magnitude. TLRs diversity in the Sierra Madre Sparrow was relatively high, which was not expected given its two small, geographically isolated populations. Genetic diversity was different (but not significantly so) between the two populations, with less diversity seen in the smaller Durango population. Population genetic structure between populations was due to isolation and different selective forces acting on different TLRs; population structure was also evident in COI. Reduction of genetic diversity in COI was observed over 20 years in the Durango population, a result likely caused by habitat loss, a factor which may be the main cause of diversity decline generally. Our results provide information related to the ways in which adaptive variation can be altered by demographic changes due to human-mediated habitat alterations. Furthermore, our findings may help to guide conservation schemes for both populations and their restricted habitat

Environmental noise exposure modifies astrocyte morphology in hippocampus of young male rats

Background: Chronic exposure to noise induces changes on the central nervous system of exposed animals. Those changes affect not only the auditory system but also other structures indirectly related to audition. The hippocampus of young animals represents a potential target for these effects because of its essential role in individuals’ adaptation to environmental challenges. Objective: The aim of the present study was to evaluate hippocampus vulnerability, assessing astrocytic morphology in an experimental model of environmental noise (EN) applied to rats in pre-pubescent stage. Materials and Methods: Weaned Wistar male rats were subjected to EN adapted to the rats’ audiogram for 15 days, 24 h daily. Once completed, plasmatic corticosterone (CORT) concentration was quantified, and immunohistochemistry for glial fibrillary acidic protein was taken in hippocampal DG, CA3, and CA1 subareas. Immunopositive cells and astrocyte arborizations were counted and compared between groups. Results: The rats subjected to noise exhibited enlarged length of astrocytes arborizations in all hippocampal subareas. Those changes were accompanied by a marked rise in serum CORT levels. Conclusions: These findings confirm hippocampal vulnerability to EN and suggest that glial cells may play an important role in the adaptation of developing the participants to noise exposure

Molecular Analysis of Streptomycin Resistance Genes in Clinical Strains of Mycobacterium tuberculosis and Biocomputational Analysis of the MtGidB L101F Variant

Globally, tuberculosis (TB) remains a prevalent threat to public health. In 2019, TB affected 10 million people and caused 1.4 million deaths. The major challenge for controlling this infectious disease is the emergence and spread of drug-resistant Mycobacterium tuberculosis, the causative agent of TB. The antibiotic streptomycin is not a current first-line anti-TB drug. However, WHO recommends its use in patients infected with a streptomycin-sensitive strain. Several mutations in the M. tuberculosisrpsL, rrs and gidB genes have proved association with streptomycin resistance. In this study, we performed a molecular analysis of these genes in clinical isolates to determine the prevalence of known or novel mutations. Here, we describe the genetic analysis outcome. Furthermore, a biocomputational analysis of the MtGidB L101F variant, the product of a novel mutation detected in gidB during molecular analysis, is also reported as a theoretical approach to study the apparent genotype-phenotype association

Effect of a multistage ultraendurance triathlon on aldosterone, vasopressin, extracellular water and urine electrolytes

Prolonged endurance exercise over several days induces increase in extracellular water (ECW). We aimed to investigate an association between the increase in ECW and the change in aldosterone and vasopressin in a multistage ultraendurance triathlon, the 'World Challenge Deca Iron Triathlon' with 10 Ironman triathlons within 10 days. Before and after each Ironman, body mass, ECW, urinary [Na(+)], urinary [K(+)], urinary specific gravity, urinary osmolality and aldosterone and vasopressin in plasma were measured. The 11 finishers completed the total distance of 38 km swimming, 1800 km cycling and 422 km running within 145.5 (18.8) hours and 25 (22) minutes. ECW increased by 0.9 (1.1) L from 14.6 (1.5) L prerace to 15.5 (1.9) L postrace (P < 0.0001). Aldosterone increased from 70.8 (104.5) pg/mL to 102.6 (104.6) pg/mL (P = 0.033); vasopressin remained unchanged. The increase in ECW was related neither to postrace aldosterone nor to postrace vasopressin. In conclusion, ECW and aldosterone increased after this multistage ultraendurance triathlon, but vasopressin did not. The increase in ECW and the increase in aldosterone were not associated
