It is surprising to think that in todays rapidly evolving world of technology, over half of the globe still does not have access to high speed internet. Creating community wireless networks has in the past been a way to provide remote communities with internet and network access. Social and Economic Effects of Community Wireless Networks and Infrastructures highlights the successes of community wireless networks but also boldly addresses the potential risk factors and broader socioeconomic concerns. This publications exploration of previous successes and failures, various designs, and potential challenges with CWNs makes it a valuable resource for researchers, practitioners, vendors, and activists.
From domestic to international settings, aid and assistance to less-developed areas has recently been bolstered by a boom in technological advances and new research. Regional Development: Concepts, Methodologies, Tools, and Applications presents a vital compendium of research detailing the latest case studies, architectures, frameworks, methodologies, and research on regional development. With over 100 chapters from authors from around the world, this three volume collection presents the most sophisticated research and developments from the field, relevant to researchers, academics, and practitioners alike. In order to stay abreast of the latest research, this book affords a vital look into regional development research.
"This book is a unique source of information outlining the importance of Information Communication Technology (ICT) adoption and diffusion, covering the Arab world's strong need for access to information systems, while still paying close attention to their culture and localization of practices"--Provided by publisher.

Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It...
Environmental conditions and changes, irrespective of source, cause a variety of stresses, one of the most prevalent of which is salt stress. Excess amount of salt in the soil adversely affects plant growth and development, and impairs production. Nearly 20% of the world’s cultivated area and nearly half of the world’s irrigated lands are affected by salinity. Processes such as seed germination, seedling growth and vigour, vegetative growth, flowering and fruit set are adversely affected by high salt concentration, ultimately causing diminished economic yield and also quality of produce. Most plants cannot tolerate salt-stress. High salt concentrations decrease the osmotic potential of s...
This book constitutes the Second 3D Head and Neck Tumor Segmentation in PET/CT Challenge, HECKTOR 2021, which was held in conjunction with the 24th International Conference on Medical Image Computing and Computer-Assisted Intervention, MICCAI 2021. The challenge took place virtually on September 27, 2021, due to the COVID-19 pandemic. The 29 contributions presented, as well as an overview paper, were carefully reviewed and selected form numerous submissions. This challenge aims to evaluate and compare the current state-of-the-art methods for automatic head and neck tumor segmentation. In the context of this challenge, a dataset of 325 delineated PET/CT images was made available for training.
