ESTUDIO DE LA INCIDENCIA DE LOS INCENDIOS EN GALICIA: UNA PERSPECTIVA SOCIOECONóMICA
JESúS BARREAL PERNAS,MARíA LOUREIRO GARCíA,JUAN PICOS MARTíN
Revista Galega de Economía , 2011,
Abstract: Muchos trabajos relacionan la acción del fuego con las aptitudes físicas o meteorológicas de la zona, pero no inciden en aquellos condicionantes de tipo socioeconómicos que afectan a la ocurrencia de incendios. A raíz de este hueco en la literatura, este trabajo analiza el impacto de variables socioeconómicas que afectan a la propagación de los incendios como son, por ejemplo, la estructura poblacional o los usos agrícolas y ganaderos. Para ello, se emplea una regresión lineal a partir de datos municipales, corrigiendo los errores estándar de los coeficientes por la heterogeneidad de cada municipio en Galicia, junto con una regresión Poisson. Entre los resultados obtenidos más relevantes destaca la importancia del papel de la densidad poblacional, junto con los diferentes usos agrarios y ganaderos de la tierra, así como la importancia de la efectividad de la organización geográfica de las medidas contra los incendios, así como las dotaciones económicas destinadas a los servicios preventivos.

Abstract: a cross-sectional descriptive research study was conducted in four polyclinics which serve as medical faculties in the formation pole of jaguey grande municipality. the objective was to assess the preparation and development of content orientation activities in human morphophysiology as a novel organizational form within the educational and teaching process of the new formation program of latin-american physicians. this instrument was administered to 308 students and 68 professors, who made up the sample from the total universe of professors and students of the above-mentioned centers. this allowed arriving at the conclusion that although the overall balance was positive, some aspects such as previous preparation of students, the instructions on some methodological aspects to carry out the activity, and the work of both professors and students to develop values for these activities must be improved.
Calculation of the Gravitational Constant G Using Electromagnetic Parameters  [PDF]
Jesús Sánchez
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2017, DOI: 10.4236/jhepgc.2017.31012
Abstract: In this paper, we will derive the following formula for the value of the gravitational constant G: \"\" (1). This equation has only 0.81% error compared to the common accepted value \"\" [1]. The parameters in the equation are the following: \"\" the fine structure constant, q the elementary charge, \"\" the mass of the electron, \"\" the permittivity of the free space, e the exponential function and \"\" the relation between a circumference and its diameter. Values attached: \"\" [2], \"\"</span
Calculation of the Fine-Structure Constant  [PDF]
Jesús Sánchez
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2018, DOI: 10.4236/jhepgc.2018.43029
Abstract: The fine-structure constant α [1] is a constant in physics that plays a fundamental role in the electromagnetic interaction. It is a dimensionless constant, defined as: \"\" (1) being q the elementary charge, ε0 the vacuum permittivity, h the Planck constant and c the speed of light in vacuum. The value shown in (1) is according CODATA 2014 [2]. In this paper, it will be explained that the fine-structure constant is one of the roots of the following equation: \"\" (2) being e the mathematical constant e (the base of the natural logarithm). One of the solutions of this equation is: \"\" (3) This means that it is equal to the CODATA value in nine decimal digits (or the seven most significant ones if you prefer). And therefore, the difference between both values is: \"\" (4) This coincidence is higher in orders of magnitude than the commonly accepted necessary to validate a theory towards experimentation. As the cosine function is periodical, the Equation (2) has infinite roots and could seem the coincidence is just by chance. But as it will be shown in the paper, the separation among the different solutions is sufficiently high to disregard this possibility. It will also be shown that another elegant way to show Equation (2) is the following (being i the imaginary unit): \"\" (5) having of course the same root (3). The possible meaning of this other representation (5) will be explained.
How to Check If a Number Is Prime Using a Finite Definite Integral  [PDF]
Jesús Sánchez
Journal of Applied Mathematics and Physics (JAMP) , 2019, DOI: 10.4236/jamp.2019.72028
Abstract: In the history of mathematics different methods have been used to detect if a number is prime or not. In this paper a new one will be shown. It will be demonstrated that if the following equation is zero for a certain number p, this number p would be prime. And being m an integer number higher than (the lowest, the most efficient the operation). \"\" . If the result is an integer, this result will tell us how many permutations of two divisors, the input number has. As you can check, no recurrent division by odd or prime numbers is done, to check if the number is prime or has divisors. To get to this point, we will do the following. First, we will create a domain with all the composite numbers. This is easy, as you can just multiply one by one all the integers (greater or equal than 2) in that domain. So, you will get all the composite numbers (not getting any prime) in that domain. Then, we will use the Fourier transform to change from this original domain (called discrete time domain in this regards) to the frequency domain. There, we can check, using Parseval’s theorem, if a certain number is there or not. The use of Parseval’s theorem leads to the above integral. If the number p that we want to check is not in the domain, the result of the integral is zero and the number is a prime. If instead, the result is an integer, this integer will tell us how many permutations of two divisors the number p has. And, in consequence information how many factors, the number p has. So, for any number p lower than 2m?- 1, you can check if it is prime or not, just making the numerical definite integration. We will apply this integral in a computer program to check the efficiency of the operation. We will check, if no further developments are done, the numerical integration is inefficient computing-wise compared with brute-force checking. To be added, is the question regarding the level of accuracy needed (number of decimals and number of steps in the numerical integration) to have a reliable result for large numbers. This will be commented on the paper, but a separate study will be needed to have detailed conclusions. Of course,
Heidegger: Being and Time and the Care for the Self  [PDF]
Jesús Adrián Escudero
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.32047
Abstract: The secret of Being and Time and of its constant cultural and philosophical presence lies in its unusual hermeneutical richness. Being and Time becomes, so to speak, a precise seismometer capable of detecting the slips and falls of the contemporary era with surprising accuracy. It offers us an exact scan of the ethical and moral conscience of our time. Being and Time does not develop a philosophical theory among others, rather it faces the challenge of thoroughly reflecting upon the dilemma that is constantly present in philosophy, namely the question of human being and its relation to being in general. From this point of view, I would like to consider the possibility of reading this fundamental work of Heidegger as an ethics of the care, that is, as book that promotes a cultivation of the self and the other.
Symbolic Deterritorialization: The Case of Gabriel Orozco  [PDF]
Jesús Segura Caba?ero
Art and Design Review (ADR) , 2015, DOI: 10.4236/adr.2015.31001
Abstract:
In a global context the artistic production has developed its critical processes from the inclusion and participation of audience in the works of art. Somehow the expansion and compression of space-time is reflected in the characteristics of many artists whose work is based on the occupying, mapping and reinterpreting of the spaces that they appropriate. This article tries to analyze the spatial and temporal turn defined by the works of artist Gabriel Orozco, The individual and collective memories, spaces of history, politics and culture are signified by the act of symbolic deterrito-rialization and reterritorialization. The article also analysed the phenomenological and material treatment of objects of Gabriel Orozco in his temporal frequency and perceptual reinterpretation in the context of cultural and political globalization in order to confront symbolic deterritorialization as a resource of his artistic production.
