El presente white paper presenta una estrategia integral para la conservación de la Amazonía mediante la diplomacia científica. Aborda la situación crítica de esta región vital, destacando su importancia ecológica y cultural. Este documento es el resultado de una metodología basada en dos procesos participativos, siendo el primero un ejercicio colaborativo dentro del Congreso de Investigación e Innovación en Sostenibilidad (SRI) y el segundo un grupo focal con expertos en diplomacia científica de América Latina, así como en el análisis de literatura. Como resultado, proponen una serie de recomendaciones prácticas y viables agrupadas en 4 categorías: 1) cooperación transdisciplinaria científica y académica, 2) el fortalecimiento de una plataforma de monitoreo conjunto, 3) la creación de un Science-Policy Hub y 4) el desarrollo de capacidades. A su vez, estas recomendaciones se categorizan en instrumentos de política pública: regulatorios (R), operacionales (O), financieros (F) y blandos (B). Un enfoque integral que combine investigación, conocimiento indígena y cooperación internacional se sugiere, junto con otras recomendaciones generales, para abordar de manera efectiva los retos ecológicos y sociales que enfrenta la Amazonía se enfatizan.

Report on a Modeling Crop and Climate Change workshop. The objectives of the workshop were: 1) train Venezuelan scientists in the use of agricultural models IBSNAT program (International Benchmark Sites Network for Agrotechnology Transfer), including discussions about their applicability and the acquisition of knowledge about the data needed for proper simulation and validation, 2) Calibrate the model of maize (CERES) for different cultivars and different regions of Venezuela using data from soil and climate corresponding to various tests, 3) Carry out model simulations under various climate scenarios to assess their potential effects on crops, 4) To strengthen the cooperation between users of IBSNAT models to make necessary tests to get a better database application thus facilitating validation and calibration of these models, and 5) To establish plans for future agricultural and meteorological research in the context of global climate change.

This works presents the design of wireless power transfer systems that can transfer power through materials such as stainless steel, aluminum, carbon fiber, and fiberglass. Wireless power transfer research has been limited to through-air applications, focusing on short distances and high efficiencies. However, complex scenarios require specific design criteria to provide the advantages of wireless power transfer for critical applications. Taking this into consideration, this work presents the extensive research towards enabling wireless power transfer systems for unconventional barriers. In the first chapter a new approach is taken towards the design of compact and embedded wireless power transfer solutions. A miniature coil is designed to transfer power through a 1 mm thick aluminum metal plate. The results are unprecedented, P_rx=100 mW, considering that through metal power transfer had only being demonstrated using large diameter coils. In addition to that, the metal barrier used is aluminum, a high conductivity material. This is important because traditional research focused on less conductive material such as stainless steel or tin. In the next chapter, we demonstrated a wireless power and data transfer system that uses a miniature coil with a size of 15 mm × 13 mm × 6 mm. Our system demonstrated that not only power but data could be transferred through an aluminum barrier using the same coil for power and data transmission. The maximum coil-to-coil power transfer efficiency is 2.4%, and the maximum harvested power is 440 mW operating at 2 kHz. Additionally, our system demonstrated that power can be harvested in variety of materials of different thicknesses. The next chapter presents a breakthrough in the field of wireless power transfer through metal by enabling long distance wireless power transfer. A large portion of the technologies for wireless power transfer are limited to short operation distances, distances around 1-10 millimeters to less than 20 cm. The operation distances are even shorter for the ...

This paper discusses a number of historical events in the 20th century from the point of view of human suffering in demographic terms, and also examines briefly the role of science and technology in these events. On the basis of this discussion it is concluded that two priorities for humanity in the 21st century are preventing climate change from reaching catastrophic tipping points, and avoiding a new world war. In both of these endeavors the scientific community can and must have a prominent role. ; Peer Reviewed ; http://deepblue.lib.umich.edu/bitstream/2027.42/61413/1/Del_siglo_XX_al_siglo_XXI_-_Desastres_naturales_y_desastres_de_origen_humano_(Apuntes_de_CyT).pdf
