Este libro tiene dos enfoques: el primero es la evaluación de parámetros para el análisis de marcha y el segundo, el análisis de detección de posibles caídas. En el análisis de la marcha se obtuvieron variables espaciotemporales de la marcha como la velocidad, cadencia, el tiempo de zancada y la longitud del paso; en el análisis de detección de caída se consideró la densidad espectral de potencia y la frecuencia fundamental e integral de la aceleración.
"All over the world, in all democratic States, independently of having a legal system based on the common law or on the civil law principles, the courts – special constitutional courts, supreme courts or ordinary courts – have the power to decide and declare the unconstitutionality of legislation or of other State acts when a particular statute violates the text of the Constitution or of its constitutional principles. This power of the courts is the consequence of the consolidation in contem-porary constitutionalism of three fundamental principles of law: first, the existence of a written or unwritten constitution or of a fundamental law, conceived as a superior law with clear supremacy ...
Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale d...
Este libro tiene el objetivo de analizar las alternativas de política pública necesarias para la preservación de la salud de la población, la reactivación de la economía y la definición de un marco institucional que facilite las relaciones entre individuos en un contexto pospandémico, mediante un enfoque multidimensional. En ese sentido, se analizan los antecedentes de las pandemias de carácter universal, el rol de las organizaciones internacionales, el papel de los bienes públicos globales, los modelos de gobernanza global desde un contexto glocal, las tendencias en investigación acerca de pandemias y sostenibilidad, los nuevos retos del Estado, el financiamiento de las pequeñas...
This paper provides estimates of output multipliers for spending in clean energy and biodiversity conservation, as well as for spending on non-ecofriendly energy and land use activities. Using a new international dataset, we find that every dollar spent on key carbon-neutral or carbon-sink activities can generate more than a dollar’s worth of economic activity. Although not all green and non-ecofriendly expenditures in the dataset are strictly comparable due to data limitations, estimated multipliers associated with spending on renewable and fossil fuel energy investment are comparable, and the former (1.1-1.5) are larger than the latter (0.5-0.6) with over 90 percent probability. These findings survive several robustness checks and lend support to bottom-up analyses arguing that stabilizing climate and reversing biodiversity loss are not at odds with continuing economic advances.

This survey book reviews four interrelated areas: (i) the relevance of heuristics in problem-solving approaches – why they are important and what research tells us about their use; (ii) the need to characterize and foster creative problem-solving approaches – what type of heuristics helps learners devise and practice creative solutions; (iii) the importance that learners formulate and pursue their own problems; and iv) the role played by the use of both multiple-purpose and ad hoc mathematical action types of technologies in problem-solving contexts – what ways of reasoning learners construct when they rely on the use of digital technologies, and how technology and technology approaches can be reconciled.
This volume is a compilation of extended abstracts of all papers presented at the 14th International Plant Nutrition Colloquium. Over 500 oral and poster presentations illustrate current knowledge and research emphasis in this subject, providing a comprehensive view of the state of plant nutrition research.
