MAs de 100.000 personas, entre ellas millares de menores de edad, mueren anualmente debido a sobredosis de fentanilo en los Estados Unidos. Esta sustancia, en sus diferentes presentaciones, encabeza la Lista I que la Convención Única de 1961 sabre Estupefacientes catalogo como estupefacientes "sujetos a todas las medidas de fiscalización". Aunque de otra índole, en Colombia los problemas que ha arrastrado esta lista resultan igualmente inquietantes. En ella se encuentran tanto la cocaína como las hojas de coca, y en las otras dos listas hay fármacos para los que estas medidas no son tan drásticas. Luego de seis décadas bajo el signo de la prohibición, el balance de la política de d...
The book will provide an update on our understanding of predator-prey through the prism of ecology, physiology, molecular biology, and mathematical modelling. The integration of these different perspectives while focusing on the microbial realm will highlight the importance of scale in ecological interactions, and their importance in applications. This book should thereby contribute to theoretical as well as to applied ecologists and microbiologists. Furthermore, the detailed but amenable chapters could serve as the basis of teaching advanced courses in (microbial) ecology and environmental microbiology.This work is a collection of articles that discuss microbial predation from a variety of ...
The document summarizes the report that, based on a review of more than 250 studies, demonstrates the importance and urgency of climate action to protect the forests of the indigenous and tribal territories of Latin America as well as the indigenous and tribal peoples who protect them. These territories contain about a third of the continent's forests. That's 14% of the carbon stored in tropical forests around the world; These territories are also home to an enormous diversity of wild fauna and flora and play a key role in stabilizing the local and regional climate. Based on an analysis of the approaches that have proven effective in recent decades, a set of investments and policies is propo...
This comprehensive volume covers recent studies into agricultural problems caused by soil and water contamination. Considering the importance of agricultural crops to human health, the editors have focused on chapters detailing the negative impact of heavy metals, excessive chemical fertilizer use, nutrients, pesticides, herbicides, insecticides, agricultural wastes and toxic pollutants, among others, on agricultural soil and crops. In addition, the chapters offer solutions to these negative impacts through various scientific approaches, including using biotechnology, nanotechnology, nutrient management strategies, biofertilizers, as well as potent PGRs and elicitors. This book serves as a k...
This book is a collection of papers presented at XIV International Scientific Conference “INTERAGROMASH 2021”, held at Don State Technical University, Rostov-on-Don, Russia, during 24–26 February 2021. The research results presented in this book cover applications of unmanned aerial systems, satellite-based applications for precision agriculture, proximal and remote sensing of soil and crop, spatial analysis, variable-rate technology, embedded sensing systems, drainage optimization and variable rate irrigation, wireless sensor networks, Internet of things, robotics, guidance and automation, software and mobile apps for precision agriculture, decision support for precision agriculture and data mining for precision agriculture.
This volume contains the Proceedings of MUSME 2014, held at Huatulco in Oaxaca, Mexico, October 2014. Topics include analysis and synthesis of mechanisms; dynamics of multibody systems; design algorithms for mechatronic systems; simulation procedures and results; prototypes and their performance; robots and micromachines; experimental validations; theory of mechatronic simulation; mechatronic systems; and control of mechatronic systems. The MUSME symposium on Multibody Systems and Mechatronics was held under the auspices of IFToMM, the International Federation for Promotion of Mechanism and Machine Science, and FeIbIM, the Iberoamerican Federation of Mechanical Engineering. Since the first symposium in 2002, MUSME events have been characterised by the way they stimulate the integration between the various mechatronics and multibody systems dynamics disciplines, present a forum for facilitating contacts among researchers and students mainly in South American countries, and serve as a joint conference for the IFToMM and FeIbIM communities.
Severe asthma is a form of asthma that responds poorly to currently available medication, and its patients represent those with greatest unmet needs. In the last 10 years, substantial progress has been made in terms of understanding some of the mechanisms that drive severe asthma; there have also been concomitant advances in the recognition of specific molecular phenotypes. This ERS Monograph covers all aspects of severe asthma – epidemiology, diagnosis, mechanisms, treatment and management – but has a particular focus on recent understanding of mechanistic heterogeneity based on an analytic approach using various ‘omics platforms applied to clinically well-defined asthma cohorts. How these advances have led to improved management targets is also emphasised. This book brings together the clinical and scientific expertise of those from around the world who are collaborating to solve the problem of severe asthma.
