The urban landscape undergoes incessant changes throughout the years through radical changes that break up the urban plot of a part of the city, which can only be recovered through historical cartography and the drawings and architectural plans of the bui... see more

Historical documents have shown their potential to infer the origin and evolution of the glacier existing in the Veleta cirque, in the massif of Sierra Nevada (Spain). This information encompasses written sources spanning from the 17th to the mid-20th cen... see more

AbstractThis article addresses the issue of human imagination from the perspective of ‘niche construction’ in the wider discussion about ‘what makes us human’ and what it means to be a ‘self’, specifically for the Christian faith and for theology. In the ... see more

El radón, segunda causa del cáncer de pulmón /Radon, the second cause of lung cancer El radón, segunda causa del cáncer de pulmón /Radon, the second cause of lung cancerObjetivo: elaborar las recomendaciones necesarias, que contribuyan a que se adopten las medidas más eficaces de protección sanitaria para disminuir los efectos del Radón a la salud.Materiales y Métodos: se emplearon diferentes Métodos teóricos tales como el histórico-lógico, utilizado el análisisde la evolución histórica e influencias principales relacionadas con el Radón y la salud, así como el análisis-síntesis y la inducción-deducción.Resultados: se logró una evaluación objetiva de las evidencias científicas acerca de los efectos del Radón sobre la salud, se elaboraron las recomendaciones necesarias, que contribuyen a que se adopten las medidas más eficaces de protección sanitaria, para disminuir la influencia de este gas radioactivo a la salud.Conclusiones: el Radón se desintegra en elementos sólidos radiactivos conocidos como partículas de la progenie de Radón (como Polonio-218, Polonio-214 y Plomo-214). La progenie del radón puede adherirse al polvo y a otras partículas que pueden ser aspiradas por los pulmones. A medida que el Radón y la progenie de éste se desintegran en el aire, liberan radiación que puede acelerar el proceso de aparición del cáncer de pulmón y dañar el ADN de las células en el interior del cuerpo.ABSTRACT Objective: to elaborate the necessary recommendations that contribute to the adoption of the most effective sanitary protection measures to reduce the effects of Radon on health.Materials and Methods: different theoretical methods were used, such as historical-logical, used the analysis of historical evolution and main influences related to Radon and health, as well as analysis-synthesis and inductiondeduction.Results: sn objective evaluation of the scientific evidences about the effects of Radon on health was achieved, the necessary recommendations were elaborated, which contribute to the adoption of the most effective measures of sanitary protection, to diminish the influence of this radioactive gas to health.Conclusions: Radon decays into radioactive solid elements known as Radon progeny particles (such as Polonium-218, Polonium-214, and Lead-214). Radon progeny can adhere to dust and other particles that can be sucked out by the lungs. As Radon and its progeny disintegrate in the air, they release radiation that can accelerate the process of lung cancer and damage the DNA of cells inside the body.Keywords: equity; Sustainable development; Science and Technology.

Influencia de las emisiones electromagnéticas no ionizantes en la salud/Influence of non-ionizing electromagnetic emissions on health Influencia de las emisiones electromagnéticas no ionizantes en la salud/Influence of non-ionizing electromagnetic emissions on healthObjetivo: elaborar las recomendaciones necesarias que contribuyan a la adopción de medidas más eficaces de protección sanitaria para disminuir los efectos de las emisiones electromagnéticas no ionizantes en la salud.Materiales y Métodos: se emplearon diferentes métodos teóricos como el histórico-lógico, utilizado en el análisis de la evolución histórica e influencias principales relacionadas con las emisiones electromagnéticas y la salud. Además, se utilizaron el análisis-síntesis y la inducción-deducción, que permitieron conformar los fundamentos teóricos y las bases empíricas del estudio.Resultados: se logró una evaluación objetiva de las evidencias científicas acerca de los potenciales efectos de los campos electromagnéticos sobre la salud y se elaboraron las recomendaciones necesarias, que contribuyen a la adopción de medidas más eficaces de protección sanitaria.Conclusiones: se espera poder despejar las dudas e incertidumbres sobre los riesgos para la salud de las emisiones electromagnéticas no ionizantes.ABSTRACTObjective: to elaborate the necessary recommendations that contribute to the adoption of more effec-tive sanitary protection measures to reduce the effects of non-ionizing electromagnetic emissions on health.Materials and Methods: different theoretical methods were used, such as the historical-logical one, used in the analysis of historical evolution and main influences related to electromagnetic emissions and health. In addition, the analysis-synthesis and the induction-deduction were used, which allowed to shape the theoretical foundations and the empirical bases of the study.Results: an objective evaluation of the scientific evidences about the potential effects of electromag- netic fields on health was achieved and the necessary recommendations were elaborated, which contribute to the adoption of more effective sanitary protection measures.Conclusions: it is expected to be able to clear up the doubts and uncertainties about the health risks of non-ionizing electromagnetic emissions.
