El uso de las TIG en la Educación. Realización de un inventario de flora

En los últimos años se ha producido una gran generalización de las Tecnologías de la Información Geográfica debido al gran incremento tanto de la información almacenada como a la universalización de este tipo de herramientas de análisis espacial. Por su gran flexibilidad y capacidad para explorar el mundo, dichas tecnologías se hacen indispensables a la hora del conocimiento y exploración del espacio geográfico y del medio ambiente. En esta comunicación se pretende poner de manifiesto la importancia de las TIG y su gran aplicabilidad al campo de la educación ambiental, en este caso concreto con la realización de un inventario de flora por parte de estudiantes universitarios

Pathology of submeasures and FσF_\sigma ideals

We address some phenomena about the interaction between lower semicontinuous submeasures on $\mathbb{N}$ and $F_{\sigma}$ ideals. We analyze the pathology degree of a submeasure and present a method to construct pathological $F_\sigma$ ideals. We give a partial answers to the question of whether every nonpathological tall $F_\sigma$ ideal is Kat\v{e}tov above the random ideal or at least has a Borel selector. Finally, we show a representation of nonpathological $F_\sigma$ ideals using sequences in Banach spaces.Comment: arXiv admin note: substantial text overlap with arXiv:2111.1059

Stabilization of Polymeric Nanofibers Layers for Use as Real-Time and In-Flow Photonic Sensors

In order to increase the sensitivity of a sensor, the relationship between its volume and the surface available to be functionalized is of great importance. Accordingly, porous materials are becoming very relevant, because they have a notable surface-to-volume ratio. Moreover, they offer the possibility to infiltrate the target substances on them. Among other porous structures, polymeric nanofibers (NFs) layers fabricated by electrospinning have emerged as a very promising alternative to low-cost and easy-to-produce high-performance photonic sensors. However, experimental results show a spectrum drift when performing sensing measurements in real-time. That drift is responsible for a significant error when trying to determine the refractive index variation for a target solution, and, because of that, for the detection of the presence of certain analytes. In order to avoid that problem, different chemical and thermal treatments were studied. The best results were obtained for thermal steps at 190 °C during times between 3 and 5 h. As a result, spectrum drifts lower than 5 pm/min and sensitivities of 518 nm/refractive index unit (RIU) in the visible range of the spectrum were achieved in different electrospun NFs sensors.This work was supported by the Spanish government through the project TEC2015-63838-C3-1-ROPTONANOSENS and from the Basque government through the project KK-2019/00101 -µ4INDUSTR

Estudio de la absorción y translocación del nitrógeno en cítricos en función del aporte estacional del abono nitrogenado mediante el uso de la técnica de dilución isotópica

Una fertilización nitrogenada racional debe contemplar no sólo el aporte de una dosis ajustada a las necesidades del cultivo, sino que a su vez debe considerar la correcta distribución de ésta durante el período de abonado. Sin embargo, no se dispone de suficiente información del efecto que la distribución estacional del fertilizante tiene sobre la absorción y la movilización del N acumulado en los órganos de reserva de los cítricos. El objetivo del presente trabajo es evaluar en plantas jóvenes de cítricos el efecto de la distribución estacional diferencial del abonado nitrogenado sobre la absorción del N y su reparto en los distintos órganos, la movilización del N acumulado en los órganos viejos de reserva hacia los óganos en desarrollo, así como su repercusión en la fructificación. De este modo, se profundizará tanto en el conocimiento de la dinámica del N en el sistema planta-suelo en los cítricos, como en los posiles factores implicados en este proceso, con el fin de ampliar las bases sobre las que descansan los criterios del abonado nitrogenado y optimizar así la aplicación estacional de los fertilizantes. Para la consecución de estos objetivos se recurrió al empleo de la técnica de dilución isotópica mediante la incorporación al sistema planta-suelo de un fertilizante marcado con el isótopo estable 15N. Éste se aplicó desde el inicio de la actividad vegetativa (principios de marzo) hasta el completo desarrollo del fruto (final de octubre) siguiento tres distribuciones estacionales. Se comparó una distribución simétrica en la que se aplicó igual fracción de la dosis desde el inicio del abonado hasta principio de julio (final de la caída fisiológica) y desde ese momento en adelante, con otras dos en las que el máximo aporte del abono (75% de la dosis) se adelantó con respecto a ésta en los meses comprendidos entre marzo y julio, ó se retrasó el periodo de julio a octubre.Martínez Alcántara, B.

Identification of fast and slow growing rhizobia nodulating soybean (Glycine max [L.] Merr) by a multiplex PCR reaction

Two DNA fragments, a 730-bp and a 900-bp fragment, one homologous to host cultivar specificity genes nolBT of Sinorhizobium fredii and the other one homologous to RSα, an insertion-like sequence present in Bradyrhizobium japonicum, were generated by polymerase chain reaction (PCR) with two pairs of primers. The amount of each fragment generated by the multiplex PCR was proportional to the amount of template DNA present. The amplification of the 900-bp RSα fragment was more sensitive, since it was amplified from a smaller amount of template DNA than the 730-bp nolBT fragment. By running the multiplex reaction in the presence of template DNA isolated from different sources, we confirmed that the reaction can discriminate between S. fredii, Bradyrhizobium japonicum and Sinorhizobium xinjiangensis.Facultad de Ciencias Agrarias y ForestalesInstituto de Fisiología Vegeta

SUFRIMIENTO EN EL ADULTO MAYOR: CAUSAS Y SOLUCIONES. UN ANÁLISIS POR SEXO

En este periodo de vida, el sufrimiento se ve acentuado debido que se sufren pérdidas biológicas y psicosocioculturales, como el desgaste físico, el dolor, la enfermedad, la no resolución de duelos, el sentirse inútiles, falta de solvencia económica, la soledad obligada, el rechazo, el abandono, entre otras (Sandoval y Varela, 1998; Varela, Ocampo, Ramírez, Restrepo, López y Cañaveral, 2006). Datos indican que las personas con edades de 60 años o más, han pasado de 42 millones en el 2000 a 100 millones en el 2025. En México se calcula que el grupo que ahora representa 13% de la población ascenderá a 16% en el 2025.El objetivo de la presente investigación consistió en describir el sufrimiento en el adulto mayor. Para ello, se trabajó con una muestra no probabilística intencional compuesta por 200 adultos mayores de la “Fundación el Pueblito de los Abuelos I.A.P.”,perteneciente al Estado de México, repartidos equitativamente por sexo. Se aplicó un cuestionario en forma de entrevista semiestructurada compuesto por seis preguntas, las aplicaciones se realizaron de forma individual con previa autorización de los participantes en un tiempo aproximado de 20 minutos. De acuerdo con los resultados obtenidos se encontró que el sufrimiento es una experiencia inevitable.Universidad Autónoma del Estado de Méxic

Satisfaction with life and its predictive factors in a cohort of fathers 24-months postpartum

Satisfaction with life is considered an essential indicator of quality of life and has implications not only for parents but also for the general health of society. It is relevant to know the factors that could explain differences in parents’ satisfaction with life. The objectives of this study were to analyse the degree of satisfaction with life of a cohort of fathers 13–24 months after the birth of their child and to analyse the predictive capacity of sociodemographic, physical, psychological, and social factors on their long-term life satisfaction. This was a longitudinal study with follow-up at 6–12 months and at 13–24 months (n = 152 fathers). The Fatigue Assessment Scale, Athens Insomnia Scale, Parental Stress Scale and short version of the Dyadic Adjustment Scale were completed online at 6–12 months. Finally, Satisfaction with Life Scale was assessed between 13 and 24 months after birth. The mean score of life satisfaction of the participants 13–24 months after the birth of their child was 18.72 (SD = 3.71) and was negatively correlated with fatigue, insomnia, and stress (p < 0.01), and positively correlated with dyadic adjustment (p < 0.01). The final hierarchical regression model showed that educational levels and insomnia were the main predictive variables for life satisfaction during the second-year postpartum. This work has important implications for clinical practice because it allows health professionals to understand the factors influencing satisfaction with life and health among fathers and to plan more effective antenatal and postnatal care.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

STUDY OF COMFORT ASSOCIATED WITH TENNIS FOOTWEAR

Since the first studies by Shackel and cols. (1969), subjective tests based on the compilation of information by means of so-called ‘comfort questionnaires’ have been widely used in ergonomics. However, this method has seldom been used in the study of sports footwear. This method implies the use of three types of questionnaires to collect information about ‘general comfort’, ‘pain in body areas’ and ‘subjective opinion’ (errors in footwear design). The present study used this method to analyze the comfort associated with the footwear used in tennis practice. The data were collected by means of personal interviews in which each item was scored according to a Likert type scale. The questionnaires were administered in different courts in 5 tennis clubs in the area of Valencia. A total of 146 questionnaires were filled out; therefore the maximum sampling error is 8% (tennis player population 4000). A descriptive analysis was made of the variables under consideration. The associations of comfort and pain in body areas and design errors were evaluated by means of cross tabulation and chi square. A factor analysis was made of pain in body areas and footwear design errors in order to define independent factors (summary variables) which grouped those variables related between them and those independent of the others, by the analysis of the principal components, rotation by the varimax method, taking values above 1 and considering the component values above 0.5. The results show that 9% of the players consider their footwear uncomfortable, 23% consider it acceptable and 68% regard it as comfortable. However, a great number of design errors were detected, as well as pain in body areas related to the use of footwear. The factor analysis allowed us to establish 4 pain factors (attributable to wrong shock absorption, wrong pressure distribution and wrong footwear structural adaptation to the foot) and 6 design errors. A later correlation analysis established a relationship among these factors, of which we can point out the correlation (r=0.1866 and p=0.022) of a wrong plantar pressure distribution and a wrong arch support.
