Urban and Regional Agriculture: Building Resilient Food Systems
explores the sustainable integration of food provision,
distribution and consumption through urban farms, agricultural
systems, user communities and structural facilities designed to
optimize food production and consumption. The book addresses the
fundamental and pressing challenges of urban planning problems,
waste minimization, food sourcing, access and equity issues, and
multiple land use optimization. Sections cover the need and
opportunities of urban agriculture, discuss tradition and
transition, space and regulatory topics, explore the range of urban
agriculture options (aquaculture to urban permaculture), discuss
support structures and constructs of physically creating urban
agricultural areas, and much more. Edited and authored by leading
experts in the field, this volume will be valuable for those

NOW A MAJOR MOTION PICTURED DIRECTED BY AND STARRING CHIWETEL
EJIOFOR - AVAILABLE ON NETFLIX When William Kamkwamba was just 14
years old, his family told him that he must leave school and come
home to work on the farm - they could no longer afford his fees.
This is his story of how he found a way to make a difference, how
he bought light to his family and village, and hope to his nation.
Malawi is a country battling AIDS, drought and famine, and in 2002,
a season of floods, followed by the most severe famine in fifty
years, brought it to its knees. Like the majority of the
population, William's family were farmers. They were totally
reliant on the maize crop. By the end of 2001, after many lean and
difficult years, there was no more crop. They were running out of
food - had nothing to sell - and had months until they would be
able to harvest their crop again. Forced to leave school at 14
years old, with no hope of raising the funds to go again, William
resorted to borrowing books from the small local library to
continue his education. One day, browsing the titles, he picked up
a book about energy, with a picture of a wind turbine on the front
cover. Fascinated by science and electricity, but knowing little
more about the technology, William decided to build his own.
Ridiculed by those around him, and exhausted from his work in the
fields every day, and using nothing more than bits of scrap metal,
old bicycle parts and wood from the blue gum tree, he slowly built
his very own windmill. This windmill has changed the world in which
William and his family live. Only 2 per cent of Malawi has
electricity; William's windmill now powers the lightbulbs and radio
for his compound. He has since built more windmills for his school
and his village. When news of William's invention spread, people
from across the globe offered to help him. Soon he was re-enrolled
in college and travelling to America to visit wind farms. This is
his incredible story. William's dream is that other African's will
learn to help themselves - one windmill and one light bulb at a
time - and that maybe one day they will be able to power their own
computers, and use the internet, and see for themselves how his
life has changed after picking up that book in the library.

Nano-Enabled Agrochemicals in Agriculture presents a targeted
overview of the safe implementation of nanotechnologies within
agricultural and horticultural settings, with the purpose of
achieving enhanced production while maintaining ecological
integrity. The growing global request for agricultural crops and
products requires high standards of quality and safety, which has
stimulated the search for new technologies that preserve their
quality and delay their decomposition. Nanotechnology may boost
plant production by improving nutrient uptake/use efficiency with
nanoformulations of fertilizers and agrochemicals for plant
enhancement, detection and treatment of diseases, and host-parasite
interactions at the molecular level using nanosensors. It also may
improve plant disease diagnostics, removal of contaminants from
soil and water, postharvest management of vegetables and flowers,
and reclamation of salt-affected soils. Although the markets for
nanoproducts and nanoformulations continue to increase, there are
also growing concerns regarding the fate and behavior of
nanomaterials in environmental systems. Exploring important topics
related to nanotechnology and nanomaterials, the book includes the
use of nanochemicals in insect pest management, as nanofungicides,
nanoherbicides, micronutrient supply, and nanosensors to monitor
crop and soil health conditions, from detection of agrochemicals to
their slow release of agrochemicals, and their impact on related
environs. This book will serve as an excellent resource for a wide
range of plant scientists who have concerns about nanomaterial
interactions with terrestrial and aquatic plants.
Quantum Materials, Devices, and Applications covers the advances
made in quantum technologies, both in research and mass production
for applications in electronics, photonics, sensing, biomedical,
environmental and agricultural applications. The book includes new
materials, new device structures that are commercially available,
and many more at the advanced research stage. It reviews the most
relevant, current and emerging materials and device structures,
organized by key applications and covers existing devices,
technologies and future possibilities within a common framework of
high-performance quantum devices. This book will be ideal for
researchers and practitioners in academia, industry and those in
materials science and engineering, electrical engineering and
physics disciplines.

Microelectromechanical systems (MEMS) device applications are
common in many areas. Micromirror arrays are used as video
projectors; microsensors find their application for measuring
acceleration, temperature, and pressure; and they can also be used
in the medical field for measuring blood pressure. Microfluidics
have also been widely employed in life sciences applications, such
as drug development and administration, point-of-care devices, and
more. To use these technologies to their fullest extent, further
research is needed. Advances in MEMS and Microfluidic Systems
explores the emerging research and advances in MEMS devices and
microfluidic systems applications. It features in-depth chapters on
microfluidic device design and fabrication as well as on the
aspects of devices/systems, characterization, and comparative
research findings. Covering topics such as biosensors,
lab-on-a-chip, and microfluidic technology, this premier reference
source is an indispensable resource for engineers, health
professionals, students and educators of higher education,
librarians, researchers, and academicians.

Targeted Cancer Imaging: Design and Synthesis of Nanoplatforms
based on Tumour Biology reviews and categorizes imaging and
targeting approaches according to cancer type, highlighting new and
safe approaches that involve membrane-coated nanoparticles, tumor
cell-derived extracellular vesicles, circulating tumor cells,
cell-free DNAs, and cancer stem cells, all with the goal of
pointing the way to developing precise targeting and
multifunctional nanotechnology-based imaging probes in the future.
This book is highly multidisciplinary, bridging the knowledge gap
between tumor biology, nanotechnology, and diagnostic imaging, and
thus making it suitable for researchers ranging from oncology to
bioengineering. Although considerable efforts have been conducted
to diagnose, improve and treat cancer in the past few decades,
existing therapeutic options are insufficient, as mortality and
morbidity rates remain high. One of the best hopes for substantial
improvement lies in early detection. Recent advances in
nanotechnology are expected to increase our current understanding
of tumor biology, allowing nanomaterials to be used for targeting
and imaging both in vitro and in vivo experimental models.
