Fresh? Juice? Paste? Canned? Stewed? Diced? Pureed? Sun Dried?
Salsa? Sauce? Ketchup? Rare is the cuisine that does not make use
of the tomato in some way, shape, or form, and the resulting
culinary popularity of the tomato has led to its proliferation in
fields and farms around the world. While some may still argue
whether the tomato is a fruit or a vegetable, few would argue that
tomato crops are highly lucrative, attractive to farmers in both
developing and developed countries and on large and small farms
alike. In fact, for those crops with significant global volume and
market share, tomatoes are the highest valued among those crops
that lack an affiliation to mind-altering drugs. But, the tomato
can be a persnickety critter. The tomato doesn't like it too hot,
too chilly, too wet, too dry, or too fertile. Many don't ripen at
the same time. Most are easily bruised. And, the selective breeding
that has yielded a larger, more attractive, and deep red tomato has
also mercilessly drained much of the taste and flavor from a once
sweet and delectable fruit. Enter the world of sensors and modern
sensing technology. The Internet of Things (IOT), when using well
chosen, well networked, and well aggregated sensors, has shown
tremendous potential to support precision agriculture, providing a
more detailed picture of crops than was previously possible using
conventional crop monitoring techniques. But, the stringent
resources and tight profit margins that are a fact of life among
many tomato growing operations, large and small, mean that sensor
technologies must be chosen and used carefully. There is no doubt
that each sensor must earn its keep in producing the perfect
tomato. With that in mind, this book explores key opportunities to
marry the potential of sensors that are networked within the IOT to
the needs of tomato production in ways that are economically
fruitful, technologically robust, and sustainable overall.
Land, as a fundamental resource in regional development, provides
major opportunities for farming, housing, urban planning, and
financing. In order to meet the requirements of the new era, every
state has developed and implemented a series of policies according
to its national specificities and to the international regulations
and trends. Geospatial Technologies for Effective Land Governance
is a pivotal reference source that provides vital research on the
application of the use of GNSS, remote sensing, and GIS. While
highlighting topics such as crop management, multispectral images,
and irrigation, this publication explores land administration,
encompassing both cadastral systems and land registration, as well
as the methods of land governance strategies. This book is ideally
designed for researchers, agricultural professionals, engineers,
environmentalists, land developers, educators, students, and
policymakers seeking current research on land and land-based
conflicts in urban and rural communities.
In today's modern world, the manufacturing industry is embracing an
energy-efficient initiative and adopting green techniques. One
aspect that has failed to adopt this scheme is flood grinding.
Current flood grinding methods increase the treatment cost of
grinding fluid and waste large quantities. In order to remain
sustainable and efficient, in-depth research is necessary to study
green grinding technologies that can ensure machining precision and
surface quality of workpiece and reduce grinding fluid-induced
environmental pollution. Enhanced Heat Transfer Mechanism of
Nanofluid MQL Cooling Grinding provides emerging research exploring
the theoretical and practical aspects of nanofluid lubrication and
its application within grinding flow and green manufacturing.
Featuring coverage on a broad range of topics such as airflow
distribution, morphology analysis, and lubrication performance,
this book is ideally designed for mechanical professionals,
engineers, manufacturers, researchers, scientists, academicians,
and students seeking current research on clean and low-carbon
precision machining methods.
Metrology is the science of measurements. As such, it deals with
the problem of obtaining knowledge of physical reality through its
quantifiable properties. The problems of measurement and of
measurement accuracy are central to all natural and technical
sciences. Now in its second edition, this monograph conveys the
fundamental theory of measurement and provides some algorithms for
result testing and validation.
This book provides a broad introductory survey of this remarkable
field, aiming to establish and clearly differentiate its physical
principles, and also to provide a snapshot portrait of many of the
most prominent current applications. Primary emphasis is placed on
developing an understanding of the fundamental photonic origin
behind the mechanism that operates in each type of effect. To this
end, the first few chapters introduce and develop core theory,
focusing on the physical significance and source of the most
salient parameters, and revealing the detailed interplay between
the key material and optical properties. Where appropriate, both
classical and photonic (quantum mechanical) representations are
discussed. The number of equations is purposely kept to a minimum,
and only a broad background in optical physics is assumed. With
copious examples and illustrations, each of the subsequent chapters
then sets out to explain and exhibit the main features and uses of
the various distinct types of mechanism that can be involved in
optical nanomanipulation, including some of the very latest
developments. To complete the scene, we also briefly discuss
applications to larger, biological particles. Overall, this book
aims to deliver to the non-specialist an amenable introduction to
the technically more advanced literature on individual manipulation
methods. Full references to the original research papers are given
throughout, and an up-to-date bibliography is provided for each
chapter, which directs the reader to other selected, more
specialised sources.
Measurement techniques form the basis of scientific, engineering,
and industrial innovations. The methods and instruments of
measurement for different fields are constantly improving, and it's
necessary to address not only their significance but also the
challenges and issues associated with them. Strategic Applications
of Measurement Technologies and Instrumentation is a collection of
innovative research on the methods and applications of measurement
techniques in medical and scientific discoveries, as well as modern
industrial applications. The book is divided into two sections with
the first focusing on the significance of measurement strategies in
physics and biomedical applications and the second examining
measurement strategies in industrial applications. Highlighting a
range of topics including material assessment, measurement
strategies, and nanoscale materials, this book is ideally designed
for engineers, academicians, researchers, scientists, software
developers, graduate students, and industry professionals.
This book provides an introduction to topological matter with a
focus on insulating bulk systems. A number of prerequisite concepts
and tools are first laid out, including the notion of symmetry
transformations, the band theory of semiconductors and aspects of
electronic transport. The main part of the book discusses realistic
models for both time-reversal-preserving and -violating topological
insulators, as well as their characteristic responses to external
perturbations. Special emphasis is given to the study of the
anomalous electric, thermal, and thermoelectric transport
properties, the theory of orbital magnetisation, and the polar Kerr
effect. The topological models studied throughout this book become
unified and generalised by means of the tenfold
topological-classification framework and the respective systematic
construction of topological invariants. This approach is further
extended to topological superconductors and topological semimetals.
This book covers a wide range of topics and aims at the transparent
presentation of the technical aspects involved. For this purpose,
homework problems are also provided in dedicated Hands-on sections.
Given its structure and the required background level of the
reader, this book is particularly recommended for graduate students
or researchers who are new to the field.
The concept of smart drug delivery vehicles involves designing and
preparing a nanostructure (or microstructure) that can be loaded
with a cargo, this can be a therapeutic drug, a contrast agent for
imaging, or a nucleic acid for gene therapy. The nanocarrier serves
to protect the cargo from degradation by enzymes in the body, to
enhance the solubility of insoluble drugs, to extend the
circulation half-life, and to enhance its penetration and
accumulation at the target site. Importantly, smart nanocarriers
can be designed to be responsive to a specific stimulus, so that
the cargo is only released or activated when desired. In this
volume we cover smart nanocarriers that respond to externally
applied stimuli that usually involve application of physical
energy. This physical energy can be applied from outside the body
and can either cause cargo release, or can activate the
nanostructure to be cytotoxic, or both. The stimuli covered include
light of various wavelengths (ultraviolet, visible or infrared),
temperature (increased or decreased), magnetic fields (used to
externally manipulate nanostructures and to activate them),
ultrasound, and electrical and mechanical forces. Finally we
discuss the issue of nanotoxicology and the future scope of the
field.
The Transmission Electron Microscope (TEM) is the ultimate tool to
see and measure structures on the nanoscale and to probe their
elemental composition and electronic structure with sub-nanometer
spatial resolution. Recent technological breakthroughs have
revolutionized our understanding of materials via use of the TEM,
and it promises to become a significant tool in understanding
biological and biomolecular systems such as viruses and DNA
molecules. This book is a practical guide for scientists who need
to use the TEM as a tool to answer questions about physical and
chemical phenomena on the nanoscale.
Hyperbolic metamaterials were originally introduced to overcome the
diffraction limit of optical imaging. Soon thereafter it was
realized that hyperbolic metamaterials demonstrate a number of
novel phenomena resulting from the broadband singular behavior of
their density of photonic states. These novel phenomena and
applications include super resolution imaging, new stealth
technologies, enhanced quantum-electrodynamic effects, thermal
hyperconductivity, superconductivity, and interesting gravitation
theory analogs. Here I review typical material systems, which
exhibit hyperbolic behavior and outline important new applications
of hyperbolic metamaterials, such as imaging experiments with
plasmonic hyperbolic metamaterials and novel VCSEL geometries, in
which the Bragg mirrors may be engineered in such a way that they
exhibit hyperbolic properties in the long wavelength infrared
range, so that they may be used to efficiently remove excess heat
from the laser cavity. I will also discuss potential applications
of self-assembled photonic hypercrystals. This system bypasses 3D
nanofabrication issues, which typically limit hyperbolic
metamaterial applications. Photonic hypercrystals combine the most
interesting features of hyperbolic metamaterials and photonic
crystals.
