Abstract: In hydrogeology it is of great interest to examine the temporal and spatial evolution of aquifers. There are different ways of modeling an aquifer: physical models, models based on analog and mathematical techniques. Usually, mathematical techniques involve complex operations difficult to understand for some people, such as differential or partial equations. In contrast, our method requires only a basic knowledge of geometry and trigonometry. Moreover, it is only necessary to know the static level of the aquifer at three different dates. Of course, the results may be limited compared to those that use advanced mathematical methods; however, our method provides a first approximation to determine the behavior of the aquifer through time. Overall, our results allowed us to follow the evolution of the aquifer in detail of various areas of increased extraction and in which removal has been increasing, but also of areas with a considerable recharge during the study period.

Abstract: the results of a descriptive cross-sectional research carried out at "dr. mario escalona reguera" teaching polyclinic, in alamar, are showed in this article aimed at dealing with what happens when one of the spouses giving origin to the families included in this study die and, therefore, they live the evolutive stage of dissolution as a group. to this end, the family cards of the family physician's offices corresponding to a basic working group were reviewed. 60 families that fulfilled all the previously established inclusion requirements were investigated. the interview was used as a technique to collect information. it was made with the previous consent of the person that had lost his/her spouse. among the most important results, it was found that widowhood is faced by a greater number of women and that in general most of the interviewed did not expect their mate's death. the family is stressed as the main network of support at this stage, which is very difficult. the mood disorders related to the loss of the spouse are more referred to by females.

Abstract: En este articulo se expresan los resultados de una investigación descriptiva de corte transversal, realizada en el Policlínico Docente "Dr. Mario Escalona Reguera", en Alamar, con la intención de abordar lo que sucede cuando muere uno de los cónyuges que dio origen a las familias incluidas en este estudio, y que por tanto, viven la etapa evolutiva de disolución como grupo. Para ello, se revisaron las fichas familiares de los consultorios pertenecientes a un Grupo Básico de Trabajo, conformando nuestro universo de investigación con 60 familias que cumplían Ios requisitos de inclusión establecidos previamente. Se utilizó la entrevista como técnica para la recogida de información, realizada con previo consentimiento del que afrontaba la pérdida del cónyuge en estas familias. Dentro los resultados más importantes se observó que la viudez, en nuestro trabajo, es afrontada por mayor número de mujeres, y que en general, la mayoría de los entrevistados no esperaban la muerte de su campanero(a). Se destaca la familia como la red de apoyo principal en esta etapa, percibida por demás, como muy difícil, y son más referidos los trastornos del estado de ánimo relacionados con la pérdida del cónyuge, en las féminas, que entre los hombres.

The dynamics of an articulated $n$-trailer vehicle

Physics , 2015,
Abstract: We derive the reduced equations of motion for an articulated $n$-trailer vehicle that moves under its own inertia on the plane. We show that the energy level surfaces in the reduced space are $(n+1)$-tori and we classify the equilibria within them, determining their stability. A thorough description of the dynamics is given in the case $n=1$.

Abstract: el objetivo de este artículo es recordar las raíces de nuestra escuela de psicología de la universidad católica y sus primeros a?os, especialmente las circunstancias de su creación y sus nexos con la psicología europea. ella se creó en 1954, primero como departamento de psicología de la facultad de filosofía, letras y educación de la universidad católica. dependía del instituto de pedagogía. posteriormente, este mismo departamento se transformó en 1957 en la actual escuela de psicología, cuyo cincuentenario se cumplirá en tres a?os más.

Abstract: jesus of nazareth?s pedagogical method of teaching in parabolas is analized from the point of view of the cognitive psychology. this teaching method has showed its effectivity for imprinting in the collective memory images and meanings that has been transmited during centuries. inside the visual histories and dramatizations of the parabolas there are meanings that people may discover and talk with others easily

Abstract: El presente artículo analiza, desde la perspectiva de la psicología cognitiva, el método pedagógico de la ense anza con parábolas, efectuado por Jesús de Nazaret. Este método de ense anza se caracteriza por su efectividad para dejar en la memoria colectiva un contenidoque se ha retrasmitido a través de los siglos. En las parábolas hay significados que pueden descubirse tras sus apariencias de ser historias sencillas y a veces dramatizadas, con características de imágenes visuales descritas verbalmente, que hacen fácil su retrasmisión Jesus of Nazareth’s pedagogical method of teaching in parabolas is analized from the point of view of the cognitive psychology. This teaching method has showed its effectivity for imprinting in the collective memory images and meanings that has been transmited during centuries. Inside the visual histories and dramatizations of the parabolas there are meanings that people may discover and talk with others easily

Abstract: eucalyptus globulus labill is one of the most planted species in chile, because of its fast growth and superior pulp qualities. nevertheless, the incidence of drought and frost damage immediately after planting is frequent. the purpose of this work was to study the effect of drought hardening on frost resistance and on variations in morphological traits that may increase drought resistance at nursery phase in four genotypes of e. globulus labill. drought hardening treatments consisted in induced water stress by watering restriction, until pre-dawn stem xylem water potentials (ψpd) reached -0.2, -1.8 and -2.6 mpa. two water stress-rewatering cycles were applied during 54 days of hardening. plant and root biomasses were affected by the interaction of drought hardening and genotypes. the rest of morphological and alometrical traits were affected independently by drought or genotype. plant height, leaf area, specific leaf area (sla), stem, and leaf biomasses decreased with drought hardening, while collar diameter was not affected. genotypes responded differentially to drought hardening in plant height, leaf area, sla, and stem, and leaf biomasses. ice nucleation temperature (int), and freezing temperatures (frt), and 50% freezing damage index of leaves (lt50) were affected by the interaction between drought hardening and genotypes. eg-13, eg-23 and eg-22 genotypes became freezing tolerant with drought hardening (-2.6 mpa). additionally, eg-14 genotype increased its freezing resistance at -1.8 mpa. therefore, freezing resistance levels and mechanism depend on genotype and drought hardening treatment. the success in tree breeding by genetic selection should be facilitated by improved understanding of the physiology of stress resistance development and survival during water supply limitations. the knowledge of morphological and freezing resistance dependency on the interaction between genotype and drought hardening may be useful nursery management information to improve pl
