A Review of Biosensors for Non-Invasive Diabetes Monitoring and Screening in Human Exhaled Breath
2019
Exhaled breath acetone has been identified as a diabetes biomarker for non-invasive diagnosis. Its detection using biosensors features has many advantages over the conventional means. This paper reviews the recent literature on the detection of exhaled breath acetone and acetone vapor of diabetic interest. The biosensors have been classified based on their transduction methods. The performance characteristics of the biosensors have been explored for comparison. The future trends are also highlighted.

Preconcentration and speciation analysis of mercury : 3D printed metal scavenger-based solid-phase extraction followed by analysis with inductively c…
2021
A selective method for preconcentration and determination of methylmercury (MeHg) and inorganic mercury (iHg) in natural water samples at the ng L−1 level has been developed. The method involves adsorption of Hg species into a 3D printed metal scavenger and sequential elution with acidic thiourea solutions before ICP-MS determination. Experimental parameters affecting the preconcentration of MeHg and iHg such as the sample matrix, effect of the flow rate on adsorption, eluent composition, and elution mode have been studied in detail. The obtained method detection limits, considering the preconcentration factors of 42 and 93, were found to be 0.05 ng L−1 and 0.08 ng L−1 for MeHg and iHg, res…
Bridging Art and Mathematics: Introduction
2017
There is a long history of interdisciplinary discussions on the relations between science, mathematics, geometry, art, aesthetics, and artistic praxes. These discussions remain active and pertinent today: the aforementioned relations are explored in various scientific communities, journals, and at conferences. Globally, numerous scholars and artists share a common interest in combining creative thinking, intellectual curiosity, and aesthetic sensibility in their work. Various experts working in different scientific and technological fields are inspired by phenomena that combine mathematical and artistic qualities. Respectively, several contemporary artists, graphic designers, craftsmen, and…
Escuela Digital: estrategias y materiales didácticos digitales en Educación Infantil y Primaria
2021
Título en español y portugués Resumen basado en la publicación El impacto de la tecnología en todos los ámbitos de la vida cotidiana es innegable. La sociedad está expuesta a una gran revolución tecnológica, con cambios acelerados y nuevas exigencias formativas y laborales. El contexto educativo no es ajeno a dichos cambios y desde la educación se están haciendo esfuerzos, más o menos notables, dirigidos a responder a las diversas demandas sociales de la revolución tecnológica.

Industrial symbiosis for increasing the efficiency in the use of materials and energy
2015
In industrial ecosystems efficiency and optimization of resources and energy, waste minimization and enhancement of the products represent an important strategy in a perspective of circular economy. From this comes the concept of industrial metabolism, intended as the whole process that includes resource fluxes through the industrial systems, their transformation and finally their disposal in minimum percentage, as waste. Currently Industrial Ecology (EI) includes all those multidisciplinary contributions for the eco-optimization of the relationship between industry and the environment as a further step forward in the concept of sustainable development. The industrial symbiosis, which repre…
Las personas mayores gays, lesbianas, bisexuales y transexuales en centros residenciales: la invisibilidad
2013
El trabajo que se expone a continuación pretende acercarse al conocimiento de un tema relativamente nuevo que empieza a mostrar su cara. Se trata, además, de un asunto controvertido y del que existe un gran desconocimiento. Es el de las personas mayores gays, lesbianas, bisexuales y transexuales (en adelante GLBT) que viven en centros residenciales. Son múltiples los estudios realizados en torno al tema de la vejez, pero escasos o casi inexistentes aquellos que hacen referencia a las personas mayores homosexuales. La realidad de estas personas es una incógnita incluso para las propias asociaciones de gays, lesbianas, bisexuales y transexuales, cuanto más para el resto de la sociedad. Dada l…
Death and religion: from the old Tolstoy to the young Wittgenstein
2012
Mi propósito es doble. Mostrar cómo la pregunta por el sentido de la vida y la matriz del sentimiento religioso del Tolstoi maduro, que él considera cristianismo verdadero, se funda en la experiencia subjetiva del miedo ante la muerte y la angustia ante la soledad que la misma comporta. Este aspecto es el núcleo de su religiosidad por cuanto de él se deriva el valor de la fraternidad, centro de una moral humanista y altruista paradójica que sacraliza el vínculo amoroso entre los hombres a la par que se fundamenta en el sometimiento a la voluntad de Dios. Por otra parte, las concepciones de Tolstoi tal como se expresan no sólo en El Evangelio Abreviado, sino también en sus relatos literarios…
Q-Coh: A tool to screen the methodological quality of cohort studies in systematic reviews and meta-analyses
2013
The evaluation of the methodological quality of primary studies in a systematic review is a key process to enhance the likelihood of achieving valid results. When considering non-randomized designs as cohort studies, this process becomes even more critical, since these designs are more susceptible to bias than randomized controlled trials are. Taking this into account, a tool, named Q-Coh, was designed with the aim to screen the methodological quality of the primary studies with a cohort design priming specificity over sensitivity in a reasonable application time. After applying it to 21 prospective cohort studies by three raters, all domains had a moderate to good agreement, with all excep…
Personality predicts social dominance in female zebra finches, Taeniopygia guttata, in a feeding context.
2011
6 pages; International audience; Although personality has been defined as a suite of correlated behaviours, most studies of animal personality actually consider correlations between a few traits. We examined the repeatability and correlational structure of five potential personality traits (activity, neophobia, exploratory tendencies, risk-taking behaviour and obstinacy), in female zebra finches. In addition, we assessed to what extent personality influenced social dominance in a feeding context in this gregarious species. All personality traits were found to be highly repeatable within individuals. In addition, except for obstinacy, all of them were related to each other, thus defining a b…
