Entrevista de las ciencias con las humanidades en el conocimiento científico actual.

En este texto se puede destacar la biografía de Adolf Meyer-Abich y que es autor de este artículo, principalmente trata de explicar la ciencia con las humanidades en la actualidad ya que estos han tenido transformaciones y cambios por completo, pero el autor quiere destacar la ciencia física más exacta que se está transformando en una parte integral de las humanidades esto quiere decir; que el conocimiento humano está desarrollándose con gran rapidez del pluralismo actual de diferentes ciencias hacia un holismo y ciencia universal

Raman cooling and heating of two trapped Ba+ ions

We study cooling of the collective vibrational motion of two 138Ba+ ions confined in an electrodynamic trap and irradiated with laser light close to the resonances S_1/2-P_1/2 (493 nm) and P_1/2-D_3/2 (650 nm). The motional state of the ions is monitored by a spatially resolving photo multiplier. Depending on detuning and intensity of the cooling lasers, macroscopically different motional states corresponding to different ion temperatures are observed. We also derive the ions' temperature from detailed analytical calculations of laser cooling taking into account the Zeeman structure of the energy levels involved. The observed motional states perfectly match the calculated temperatures. Significant heating is observed in the vicinity of the dark resonances of the Zeeman-split S_1/2-D_3/2 Raman transitions. Here two-photon processes dominate the interaction between lasers and ions. Parameter regimes of laser light are identified that imply most efficient laser cooling.Comment: 8 pages, 5 figure

Investigating The Universality And Comprehensive Ability Of Measures To Assess The State Of Workload

Measures of workload have been developed on the basis of the various definitions, some are designed to capture the multi-dimensional aspects of a unitary resource pool (Kahneman, 1973) while others are developed on the basis of multiple resource theory (Wickens, 2002). Although many theory based workload measures exist, others have often been constructed to serve the purpose of specific experimental tasks. As a result, it is likely that not every workload measure is reliable and valid for all tasks, much less each domain. To date, no single measure, systematically tested across experimental tasks, domains, and other measures is considered a universal measure of workload. Most researchers would argue that multiple measures from various categories should be applied to a given task to comprehensively assess workload. The goal for Study 1 to establish task load manipulations for two theoretically different tasks that induce distinct levels of workload assessed by both subjective and performance measures was successful. The results of the subjective responses support standardization and validation of the tasks and demands of that task for investigating workload. After investigating the use of subjective and objective measures of workload to identify a universal and comprehensive measure or set of measures, based on Study 2, it can only be concluded that not one or a set of measures exists. Arguably, it is not to say that one will never be conceived and developed, but at this time, one does not reside in the psychometric catalog. Instead, it appears that a more suitable approach is to customize a set of workload measures based on the task. The novel approach of assessing the sensitivity and comprehensive ability of conjointly utilizing subjective, performance, and physiological workload measures for theoretically different tasks within the same domain contributes to the theory by laying the foundation for improving methodology for researching workload. The applicable contribution of this project is a stepping-stone towards developing complex profiles of workload for use in closed-loop systems, such as human-robot team iv interaction. Identifying the best combination of workload measures enables human factors practitioners, trainers, and task designers to improve methodology and evaluation of system designs, training requirements, and personnel selectio

Educacão em saúde voltada à prevenção de gravidez na adolêscencia no município Penedo-AL

Elaborou-se um projeto de intervenção comunitária sobre as causas e fatores de risco da gravidez na adolescência, numa área de saúde do município de Penedo/Alagoas. Para este trabalho primeiramente realiza-se entrevista com adolescentes para conhecer sobre o nível de conhecimento que eles tem sobre as causas e consequências da gravidez na adolescência, com o consentimento informado de pais e filhos, a segunda etapa corresponde à elaboração do programa educativo sobre o conhecimento dos fatores de riscos da gravidez na adolescência, em um terceiro momento se realizo uma avaliação novamente do domínio do tema da população estudada, medindo o impacto que causa nossa intervenção., avaliando-se a efetividade do projeto. Estratégico Situacional. Para a realização do trabalho se tiveram em conta alguns aspectos que formam parte dos nós críticos do problema em questão tais como gravidez na adolescência. Trabalhar sobre essa dificuldade permitiu uma melhor aquisição de informação, conhecimento e habilidades para educação em saúde de adolescentes na prevenção de gravidez na área de abrangênci

El problema de Metapán

Cada río trata de establecer un desnivel continuo desde su nacimiento hasta la base de erosión, nivelando saltos y otras interrupciones bruscas de su lecho. El límite entre cauce inferior (zona de acumulación) y cauce superior (zona de erosión) camina durante este proceso lentamente hacia arriba. Dicho límite, en el río San José, se encuentra actualmente a unos 2,5 kms río arriba de Metapán. Desde aquí hasta la embocadura, el lecho del río se levanta continuamente por la acumulación de los sedimentos
