Revisiting John Locke for Thinking About the Global Age: Knowledge, Politics, Religion, and Education
Theme of this text: importance of John Locke´s thought, British empiricist philosopher, concerning knowledge, politics, religion and education in global age. Question one searches for answering: nowadays, in global age, why is a thinker like John Locke still so important in order to support reflections about epistemological, political, religious and educational questions? Kind of research reported is a theoretical approach. Discourse development has followed these steps: first, considerations about his theory of knowledge; second, approaches concerning his political theory; third, reflections under his ideas on religion; fourth, discussions concerning his thoughts over education. Results of this inquiry: he is one of the most eminent theorists of experience and it is essential to build knowledge; therefore, his thought must not be neglected; he is also very important to reflect about natural rights of mankind, which must be granted by Commonwealth; his ideas over toleration, which reinforce distinction between Church and Commonwealth, are still useful to think about how to deal with several religious beliefs and political opinions; his educational thought outlines that education is a psychophysical process that must equally treat both body and soul. Then, he must be recommended and also revisited in order to think about present global age
Seismic Risk Assessment of the Thin and Lightly Reinforced Concrete Wall Building System
La construcción industrializada de edificios de muros delgados de concreto reforzado es una práctica de construcción común en el norte de Sudamérica. En Colombia, estos muros suelen tener espesores entre 80 y 150 mm, bajas cuantías de refuerzo (ρl < 0,4%) en forma de mallas electrosoldadas trefiladas en frío y baja carga axial (P ≤ 0,10f'cAg). Hasta ahora, no ha habido eventos sísmicos importantes en la región que hayan puesto a prueba el desempeño estructural de estos sistemas. Sin embargo, recientes pruebas experimentales sugieren que los muros con espesores reducidos tienen una capacidad de ductilidad limitada y un desempeño inferior al esperado según el reglamento colombiano NSR-10. Este estudio presenta una metodología para evaluar el riesgo sísmico de arquetipos de edificios de muros delgados mediante análisis dinámicos no lineales consistentes con la amenaza de la zona. Se presenta un caso de estudio con características geométricas y configuración de refuerzo compatibles con la tipología de construcción colombiana en zonas de amenaza sísmica alta. La respuesta sísmica de las estructuras se evalúa en términos de capacidad de deformación y demanda local (a nivel de sección de los elementos) y global (comportamiento general de la estructura) en el rango inelástico. Los resultados del análisis se utilizan para desarrollar curvas de fragilidad y cuantificar la vulnerabilidad y el riesgo sísmico de edificios construidos con este sistema. Los resultados indican que las estructuras de muros delgados son vulnerables a altas demandas sísmicas, pero esto no se traduce necesariamente en altas tasas de excedencia de estados límites.MaestríaMagister en Ingeniería Civi
A general lineability criterion for complements of vector spaces
In 1931, Banach proved that, far from being exceptional objects, the
Weierstrass functions form a residual set in the space of
continuous functions. Later on, in 1966, V. I. Gurariy showed that, except for
zero, there is an infinite-dimensional linear subspace of Weierstrass
functions. This was the first example of \textit{lineability}. Over the last
decade, this topic has attracted the continuous attention of the mathematical
community, with a steady stream of papers being published, many of them in
highly ranked mathematical journals. Several lineability criteria are known and
applied to specific topological vector spaces. To paraphrase L.
Bernal-Gonz\'alez and M. O. Cabrera in [J. Funct. Anal. \textbf{266} (2014),
3997-4025], ``sometimes, such criteria furnish unified proofs of a number of
scattered results in the related literature''. In this article, we provide a
general lineability criterion in the context of complements of vector spaces
Understanding portuguese consumer acceptability of seaweed-based snacks
The world's population is growing and that. As a result, the world's resources are becoming increasingly scarce. Over the years, the food industry has become more competitive, while consumers have become more concerned about what they eat, especially the nutritional and health benefits of the food they eat. The consumption of algae has proven to be an alternative to the environmental saturation resulting from the production of more traditional foods, and therefore the promotion of the consumption of algae is of great importance, since it tends to be a healthy alternative that benefits both human beings and the planet's ecosystem, promoting the sustainability of the planet.
This study attempts to validate an alternative way of consuming seaweed: seaweed snacks. In order to explore understand the Portuguese consumer acceptability of seaweed-based snacks, will be evaluate the impact of the independent variables: familiarity, knowledge of seaweed, neophobia and product certification and labelling, on the independent variable will be assessed.
It was observed that the respondents claimed not to have sufficient knowledge about seaweed, despite having some previous experience with it: seeing and eating seaweed-based food. The product that stood out the most was the seaweed-based snack, confirming that it could be a good bet for the market to overcome the barriers inherent in seaweed consumption. Labelling is also an aid in choosing healthier food products and can also be very useful in spreading nutritional and health information about algae-based foods
Reproducibility of the lactate minimum test in wistar rats after training at the maximal lactate steady state intensity
The aim of this study was to verify the reproducibility of the lactate minim (LM) test after four weeks of aerobic training, as well as its validity with the maximal lactate steady state (MLSS) in Wistar rats submitted to swimming exercise. Ten rats with 90 days were used. The aerobic and anaerobic capacity was determined by the LM test before and after the training. The protocol of MLSS was also applied before and after the training. Training was accomplished for four weeks, being the first two weeks with a volume of 30 minutes and the other two weeks with a volume of 45 minutes, both in the intensity of MLSS. With the training, the intensity of LM and the concentration of LM [Lac] increased of 16.19±1.87 to 18.84 ± 0.96 g and of 3.58±1.78 to 5.42±1.13 mmol/L, respectively. The intensity of MLSS increased of 18.64±1.75 to 19.97±2.15 g. The intensity of LM and MLSS in the pre and post-training phase presented high correlations (r=0.92) and (r=0.87), respectively. It was concluded that the LM test presented sensibility to the effects of the training, as well as validity with gold standard test (MLSS) in rats submitted to swimming exercise
Simultaneous Papillary Carcinoma in Thyroglossal Duct Cyst and Thyroid
Thyroglossal duct cyst (TDC) is a cystic expansion of a remnant of the thyroglossal duct tract. Carcinomas in the TDC are extremely rare and are usually an incidental finding after the Sistrunk procedure. In this report, an unusual case of a 36-year-old woman with concurrent papillary thyroid carcinoma arising in the TDC and on the thyroid gland is presented, followed by a discussion of the controversies surrounding the possible origins of a papillary carcinoma in the TDC, as well as the current management options
