Tackling Food Insecurity. A Case for Organic Agriculture
Essay from the year 2021 in the subject Agrarian Studies, grade: A2, Obafemi Awolowo University, language: English, abstract: This essay discusses the importance of tackling food insecurity. According to a Food and Agriculture organization (FAO) 2017 report on the future of food; the world today is increasingly confronted by multidimensional challenges from drought, food shortages, diseases, and global climate changes to an ever-increasing global population. As they are associated with one another, it is seen that to address some of these challenges, the issue of food security has to be tackled. To this effect, the agriculture industry thus faces an enormous task of increasing food production in an equitable and sustainable manner.
Hole in the Wall
The Automated Teller Machine (ATM) is the world's original 'fintech'. Its invention in 1967 changed our world. And it's doing it still. Yet, despite over half the world's population relying on the cash they dispense, they remain unnoticed and under-appreciated. We pass them nearly every day, not pausing to reflect on the crucial role they play in society, not just in facilitating access to our money, but in alleviating poverty and reducing disaster risk. By telling the story of how these humble but sophisticated machines came to be invented and how they have developed since, this book pays them the respect they deserve.

Composite Materials in Design Processes
The use of composite materials in the design process allows one to tailer a component's mechanical properties, thus reducing its overall weight. On the one hand, the possible combinations of matrices, reinforcements, and technologies provides more options to the designer. On the other hand, it increases the fields that need to be investigated in order to obtain all the information requested for a safe design. This Applied Sciences Special Issue, "Composite Materials in Design Processes", collects recent advances in the design methods for components made of composites and composite material properties at a laminate level or using a multi-scale approach.

It provides a useful source of information for engineers and specialists, as well as for undergraduate and postgraduate students, in the areas of environmental science and engineering.
Recycling of Textile Waste
Recycling is a process of collection and segregation, processing and remanufacturing, purchase and use. Textile recycling is the process by which old clothing and other textiles are recovered for reuse or material recovery. It is the basis for the textile recycling industry. The necessary steps in the textile recycling process involve the donation, collection, sorting and processing of textiles, and then subsequent transportation to end users of used garments, rags or other recovered materials. Textile industry is accused of being one of the most polluting industries. Not only production but consumption of textiles also produces waste. Textile recycling is the reuse as well as reproduction of fibres from textile waste.Textile recycling is one of the oldest and most established recycling industries in the world, yet, few people understand the recycling industry. Textiles have been recycled since the eighteenth century when the Napoleanic war caused virgin wool shortages and required that wool fibres be garneted into new yarns. Even though the textile industry has been utilizing used fibres for at least 150 years, the markets for recycled textile fibres continue to evolve.Traditional sources of textile waste come from three different sources - fibre, yarn and fabric processing, Sewn products manufacture, disc textile at cutting waste at all the manufacturing level are considered pre-consumer waste and are easier to recycle because the fibres, dyes and finishes are known and in like-new condition.The financial benefits are making money selling recyclables and community financial benefits. Recycling builds community since people work together, communicate, share ideas and support each other.Recycling creates jobs. For example, 10,000 tons of waste incinerated, creates 1 job, landfilled creates 6 jobs and recycled creates 36 jobs. Recycling helps build a strong economy, lower waste management costs, cheaper production materials, energy savings, and job creation. Recycling helps protect environment due to reduced contamination risk from landfills, reduced pollution, reduced environmental impact from mining or extracting fresh raw materials. Recycling is a way of life as once we make the choice to recycle and stick to that choice every day, it becomes second nature and a way of life.

Wide Bandgap Based Devices
Emerging wide bandgap (WBG) semiconductors hold the potential to advance the global industry in the same way that, more than 50 years ago, the invention of the silicon (Si) chip enabled the modern computer era. SiC- and GaN-based devices are starting to become more commercially available. Smaller, faster, and more efficient than their counterpart Si-based components, these WBG devices also offer greater expected reliability in tougher operating conditions. Furthermore, in this frame, a new class of microelectronic-grade semiconducting materials that have an even larger bandgap than the previously established wide bandgap semiconductors, such as GaN and SiC, have been created, and are thus referred to as "ultra-wide bandgap" materials. These materials, which include AlGaN, AlN, diamond, Ga2O3, and BN, offer theoretically superior properties, including a higher critical breakdown field, higher temperature operation, and potentially higher radiation tolerance. These attributes, in turn, make it possible to use revolutionary new devices for extreme environments, such as high-efficiency power transistors, because of the improved Baliga figure of merit, ultra-high voltage pulsed power switches, high-efficiency UV-LEDs, and electronics. This Special Issue aims to collect high quality research papers, short communications, and review articles that focus on wide bandgap device design, fabrication, and advanced characterization. The Special Issue will also publish selected papers from the 43rd Workshop on Compound Semiconductor Devices and Integrated Circuits, held in France (WOCSDICE 2019), which brings together scientists and engineers working in the area of III-V, and other compound semiconductor devices and integrated circuits. In particular, the following topics are addressed: - GaN- and SiC-based devices for power and optoelectronic applications - Ga2O3 substrate development, and Ga2O3 thin film growth, doping, and devices - AlN-based emerging material and devices - BN epitaxial growth, characterization, and devices
SUMP for Cities’ Sustainable Development
In a rapidly changing world, it is necessary to increase the engagement of local authorities and stakeholders to make urban mobility cleaner and more sustainable. The best way is to combine great ideas and innovative measures with political support. This Special Issue consists of six articles analyzing the impact of SUMPs. Innovative measures have been proposed to change urban transport systems towards sustainability: Chinese research has analyzed the tourist flow of Tibet using innovative technologies: mobile phone data, visualizations using GIS, and social networks. Lithuanian authors proposed three autonomous car travel development concepts that should become a conceptual tool in the development of ITS and C-ITS. An English scientific paper is based on a review of local transport policy documents from 13 cities in four countries. Most cities seek to reduce car travel as a proportion of trips. Experience from Slovenia shows that the comprehensive traffic calming approach has positive effects and contributes to achieving sustainable mobility. Korean researchers used the GINI coefficient to evaluate the bus system to identify bus nodes in order of importance. The last article described that multicriteria decision-making methods have been successfully used for assessing the effectiveness of sustainable transport systems, and a universal evaluation model was proposed.
Biomedical Image Processing and Classification
Biomedical image processing is an interdisciplinary field involving a variety of disciplines, e.g., electronics, computer science, physics, mathematics, physiology, and medicine. Several imaging techniques have been developed, providing many approaches to the study of the human body. Biomedical image processing is finding an increasing number of important applications in, for example, the study of the internal structure or function of an organ and the diagnosis or treatment of a disease. If associated with classification methods, it can support the development of computer-aided diagnosis (CAD) systems, which could help medical doctors in refining their clinical picture.
Organic Philosophy and Climate Change
The boundaries of organic evolution on Earth existed in the interactions of the double helix with the environment. However, modern humanity's thought processes created new boundaries, perceptions and value systems that altered the course of this evolution. As a result, the plants, animals, insects and microbes of the planet, with their muted voices, are losing the battle with the creators of technology who declared their arrogant beliefs in a cacophony. This publication requires a paradigm shift by the general reader because it essentially goes against most of what was taught since childhood. It is hoped this volume will introduce a sense of humility and reality with an awareness of balance and equality as exhibited by our quickly disappearing indigenous tribes such as those of the Amazon river basin.
Quadcopter Physical Model, Axis and GPS Control
This booklet is intended for everyone who wants to set the control parameters of a quadcopter or who works on his own projects with quadcopters. For anyone who wants to understand why a quadrocopter flies at all, or how it realizes the self-balancing, and how to choose controller parameters so that it reaches a predetermined angle of attack in nick or roll, the reading is recommended. For this purpose, the flight mechanics is first derived in the chapter 'Physical Model'. This leads to the simple model of an axis with two motors. So that a quadcopter can move in one direction, a regulation must be provided which brings it into an angle of attack. This is dealt with in the 'Axis Control' chapter. The drift itself is then either controlled visually by the quadcopter pilot himself or with a superimposed controller that uses GPS as a sensor. This regulation is dealt with in the chapter 'GPS Control'. There are many controller structures for quadcopters in the literature. The one discussed here was deliberately chosen so that it can be implemented with as many flight controllers as possible. In particular, the separation into a subordinate axis control and a superimposed GPS control corresponds to the state of the art in quadcopter controls.

Sustainable Construction
Construction is one of the main sectors that generates greenhouse gases. This industry consumes large amounts of raw materials, such as stone, timber, water, etc. Additionally, infrastructure should provide service over many years without safety problems. Therefore, their correct design, construction, maintenance, and dismantling are essential to reducing economic, environmental, and societal consequences. That is why promoting sustainable construction has recently become extremely important. To help address and resolve these types of questions, this book explores new ways of reducing the environmental impacts caused by the construction sector, as well promotes social progress and economic growth. The chapters collect the papers included in the "Sustainable Construction" Special Issue of the Sustainability journal. The papers cover a wide spectrum of issues related to the use of sustainable materials in construction, the optimization of designs based con sustainable indicators, the life-cycle assessment, the decision-making processes that integrate economic, social, and environmental aspects, and the promotion of durable materials that reduce future maintenance.

Finally, the circular economy as an economic model of production and consumption that involves reusing, repairing, refurbishing, and recycling materials after their service life are presented in this book.
Microgrids
Microgrids are a growing segment of the energy industry, representing a paradigm shift from centralized structures toward more localized, autonomous, dynamic, and bi-directional energy networks, especially in cities and communities. The ability to isolate from the larger grid makes microgrids resilient, while their capability of forming scalable energy clusters permits the delivery of services that make the grid more sustainable and competitive. Through an optimal design and management process, microgrids could also provide efficient, low-cost, clean energy and help to improve the operation and stability of regional energy systems. This book covers these promising and dynamic areas of research and development and gathers contributions on different aspects of microgrids in an aim to impart higher degrees of sustainability and resilience to energy systems.
Environmental Compatible Circuit Breaker Technologies
Recent research and development in the field of high-current circuit breaker technology are devoted to meeting two challenges: the environmental compatibility and new demands on electrical grids caused by the increasing use of renewable energies. Electric arcs in gases or a vacuum are the key component in the technology at present and will play a key role also in future concepts, e.g., for hybrid and fast switching required for high-voltage direct-current (HVDC) transmission systems. In addition, the replacement of the environmentally harmful SF6 in gas breakers and gas-insulated switchgear is an actual issue. This Special Issue comprises eight peer-reviewed papers, which address recent studies of switching arcs and electrical insulation at high and medium voltage. Three papers consider issues of the replacement of the environmentally harmful SF6 by CO2 in high-voltage gas circuit breakers. One paper deals with fast switching in air with relevance for hybrid fault current limiters and hybrid HVDC interrupters. The other four papers illustrate actual research on vacuum current breakers as an additional option for environmentally compatible switchgear; fundamental studies of the vacuum arc ignition, as well as concepts for the use of vacuum arcs for DC interruption.

A Systems Approach for River and River Basin Restoration
Communities increasingly find that the water quality, water levels, or some other resource indicator in their river basins do not meet their expectations. This discrepancy between the desired and actual state of the resource leads to efforts in river basin restoration. River basins are complex systems, and too often, restoration efforts are ineffective due to a lack of understanding of the purpose of the system, defined by the system structure and function. The river basin structure includes stocks (e.g., water level or quality), inflows (e.g., precipitation or fertilization), outflows (e.g., evaporation or runoff), and positive and negative feedback loops with delays in responsiveness, all of which function to change or stabilize the state of the system (e.g., the stock of interest, such as water level or quality). External drivers on this structure, together with goals and rules, contribute to how a river basin functions. This book reviews several new research projects to identify and rank the twelve most effective leverage points to address discrepancies between the desired and actual state of the river basin system. This book demonstrates that river basin restoration is most likely to succeed when we change paradigms rather than try to change the system elements, as the paradigm will establish the system goals, structure, rules, delays, and parameters.

Advancements in Real-Time Simulation of Power and Energy Systems
Modern power and energy systems are characterized by the wide integration of distributed generation, storage and electric vehicles, adoption of ICT solutions, and interconnection of different energy carriers and consumer engagement, posing new challenges and creating new opportunities. Advanced testing and validation methods are needed to efficiently validate power equipment and controls in the contemporary complex environment and support the transition to a cleaner and sustainable energy system. Real-time hardware-in-the-loop (HIL) simulation has proven to be an effective method for validating and de-risking power system equipment in highly realistic, flexible, and repeatable conditions. Controller hardware-in-the-loop (CHIL) and power hardware-in-the-loop (PHIL) are the two main HIL simulation methods used in industry and academia that contribute to system-level testing enhancement by exploiting the flexibility of digital simulations in testing actual controllers and power equipment. This book addresses recent advances in real-time HIL simulation in several domains (also in new and promising areas), including technique improvements to promote its wider use. It is composed of 14 papers dealing with advances in HIL testing of power electronic converters, power system protection, modeling for real-time digital simulation, co-simulation, geographically distributed HIL, and multiphysics HIL, among other topics.
Coastal Geohazard and Offshore Geotechnics
With rapid developments being made in the exploration of marine resources, coastal geohazard and offshore geotechnics have attracted a great deal of attention from coastal geotechnical engineers, with significant progress being made in recent years. Due to the complicated nature of marine environmnets, there are numerous natural marine geohazard preset throughout the world's marine areas, e.g., the South China Sea. In addition, damage to offshore infrastructure (e.g., monopiles, bridge piers, etc.) and their supporting installations (pipelines, power transmission cables, etc.) has occurred in the last decades. A better understanding of the fundamental mechanisms and soil behavior of the seabed in marine environments will help engineers in the design and planning processes of coastal geotechnical engineering projects. The purpose of this book is to present the recent advances made in the field of coastal geohazards and offshore geotechnics. The book will provide researchers with information reagrding the recent developments in the field, and possible future developments. The book is composed of eighteen papers, covering three main themes: (1) the mechanisms of fluid-seabed interactions and the instability associated with seabeds when they are under dynamic loading (papers 1-5); (2) evaluation of the stability of marine infrastructure, including pipelines (papers 6-8), piled foundation and bridge piers (papers 9-12), submarine tunnels (paper 13), and other supported foundations (paper 14); and (3) coastal geohazards, including submarine landslides and slope stability (papers 15-16) and other geohazard issues (papers 17-18). The editors hope that this book will functoin as a guide for researchers, scientists, and scholars, as well as practitioners of coastal and offshore engineering.

Mitigating Tomato post-harvest Losses. Participation Responses to recommended Technology
Research Paper (postgraduate) from the year 2020 in the subject Food Technology, Federal University of Technology, Owerri, language: English, abstract: This study investigated the economics of post-harvest losses among tomato farmers in Barkin-Ladi Local Government Area of Plateau State, Nigeria. Multi-stage sampling techniques were used in selecting respondents for this study. Primary data was collected using structured questionnaires. Descriptive statistics, Likert method and ordinary least square regression model; were analytical techniques employed. The result revealed that 62% of the respondents were males, 72% are married. The mean age was 42 years. Most (38%) attained primary education, 48% had a household size with population of 1-5 people. The mean year of experience was 17 years. Most (78%) used woven baskets in packaging their produce. The prevalent improved post-harvest techniques were; appropriate harvesting techniques (2.79), improved drying techniques (2.69) and improved processing technology (2.62) as indicated by their significant mean scores. The estimated value of tomato post-harvest loss per 50kg was 27.5%. Thus, estimated gross margin were ₦5,400 (without loss) and ₦3,910 (with loss) respectively. The coefficients of farming experience (-0.421), distance to markets (0.413), age of fruit at harvest (0.519), quantity of fruits harvested (0.387) and post-harvest practices (-0.396) were statistically significant at 5% level. The estimated coefficient of multiple determination (R2) was 0.795, suggesting that 79% of post-harvest losses were attributable to the variables in the regression model. The constraints identified affected tomato post-harvest loss reduction. Adoption of improved post-harvest techniques, storage and processing facilities, provision of improved market linkages and access to agricultural credit, extension contact and formation of producer cooperatives are strongly recommended for reduced wastages.

Technological Internationalism and World Order
Between 1920 and 1950, British and US internationalists called for aviation and atomic energy to be taken out of the hands of nation-states, and instead used by international organizations such as the League of Nations and the United Nations. An international air force was to enforce collective security and internationalized civil aviation was to bind the world together through trade and communication. The bomber and the atomic bomb, now associated with death and devastation, were to be instruments of world peace. Drawing on rich archival research and focusing on public and private discourse relating to the control of aviation and atomic energy, Waqar H. Zaidi highlights neglected technological and militaristic strands in twentieth-century liberal internationalism, and transforms our understanding of the place of science and technology in twentieth-century international relations.
The Reluctant Soldier
Sergeant Smith didn't want to be in the army. He was called up for WW2 and assigned to the Signals due to his experience with telephones at the Post Office. These are his personal recollections of the war. He was rebellious and lived for the day, scheming up ways to get extra beer money. He spent as much of the war as possible drinking and dancing. When he reached his 80s, his daughter sat him down, recorded his stories and transcribed them. This is the dialogue between them and his personal account of the war.

Investigation of a Spiral Antenna
The global need for harmless and pure renewable energy is always a subject of foremost interest to the society. A continuous and steady source of energy for mankind is the Sun, and harvesting it helps in solving the energy requirement. However, conventional harvesting of solar energy by the help of photovoltaic cells has its own limitations on its efficiency, and its availability which depend on the weather conditions and the time of the day. Apart from solar energy there are also other available natural sources of energy such as wind energy, kinetic energy which make use of massive turbines and transformers which are subject to wear and tear and need continuous maintenance. Whereas, Radio Frequency (RF) energy is a readily available source from the surrounding air at anytime of the day and at any weather conditions. Although, the available energy levels are quite low and are not constant, it still remains to be a promising solution in powering many of the consumer-oriented portable devices, RFID tags, wireless sensors and many more. Moreover, this system does not require bulky components to convert the microwave energy to a usable power.

Managing Water Resources in Large River Basins
Management of water resources in large rivers basins typically differs in important ways from management in smaller basins. While in smaller basins the focus of water resources management may be on project implementation, irrigation and drainage management, water use efficiency and flood operations; in larger basins, because of the greater complexity and competing interests, there is often a greater need for long-term strategic river basin planning across sectors and jurisdictions, and considering social, environmental, and economic outcomes. This puts a focus on sustainable development, including consumptive water use and non-consumptive water uses, such as inland navigation and hydropower. It also requires the consideration of hard or technical issues-data, modeling, infrastructure-as well as soft issues of governance, including legal frameworks, policies, institutions, and political economy. Rapidly evolving technologies could play a significant role in managing large basins. This Special Issue of Water traverses these hard and soft aspects of managing water resources in large river basins through a series of diverse case studies from across the globe that demonstrate recent advances in both technical and governance innovations in river basin management.
Design and implementation of programming languages
Programming bananas are grammatical language structures in computers by which an algorithm can be described by different grammatical structures for executing a computer, making it possible to write programs to produce new software.Usually, any programming language has a software environment for entering, executing, compiling, and debugging program text.A programming language is a synthetic English language designed to express computations that can be performed by a machine (especially a computer).
Circuits and Systems Advances in Near Threshold Computing
Modern society is witnessing a sea change in ubiquitous computing, in which people have embraced computing systems as an indispensable part of day-to-day existence. Computation, storage, and communication abilities of smartphones, for example, have undergone monumental changes over the past decade. However, global emphasis on creating and sustaining green environments is leading to a rapid and ongoing proliferation of edge computing systems and applications. As a broad spectrum of healthcare, home, and transport applications shift to the edge of the network, near-threshold computing (NTC) is emerging as one of the promising low-power computing platforms. An NTC device sets its supply voltage close to its threshold voltage, dramatically reducing the energy consumption. Despite showing substantial promise in terms of energy efficiency, NTC is yet to see widescale commercial adoption. This is because circuits and systems operating with NTC suffer from several problems, including increased sensitivity to process variation, reliability problems, performance degradation, and security vulnerabilities, to name a few. To realize its potential, we need designs, techniques, and solutions to overcome these challenges associated with NTC circuits and systems. The readers of this book will be able to familiarize themselves with recent advances in electronics systems, focusing on near-threshold computing.

SEDC Motor Control
The speed of a separately excited DC motor can be controlled from below and up to rated speed using DC chopper as a converter. The DC chopper firing circuit receives signals from speed controller and then DC chopper gives variable output voltage to the armature of the separately excited DC motor for achieving desired speed. There are two control loops, one for controlling armature current and second for controlling speed. The controllers are used Proportion-Integral (PI) type which removes the delay and provide fast speed response. The mathematical modeling of separately excited DC motor is done. The mathematical model of closed loop speed control of separately excited DC motor using dc chopper is obtained. The optimization of speed controller transfer function is done using modulus hugging approach, in order to get stable and fast response of the closed loop system. By this approach gain of the closed loop system becomes unity. The stability of overall transfer function of closed loop system is checked by Routh-Hurwitz criteria and Bode plot, before and after designing of speed controller using modulus hugging approach.

Detection of Microcalcification in Mammograms Using AI & ML Techniques
One of the new modern and most efficient methods for breast cancer early detection is mammography. A new method for the detection and classification of microcalcifications is presented. It can be done in four stages: first, preprocessing stage deals with noise removal, and normalized the image. The second stage, Fuzzy c-Means clustering (FCM) is used for segmentation and pectoral muscle extraction using area calculation and finally microcalcifications detection. The third stage consists of two-dimensional discrete wavelet transforms are extracted from the detection of microcalcifications. And then, nine statistical features are calculated from the LL band of the wavelet transform. Finally, the extracted features are fed as input to the Artificial Neural Network and are classified into normal or abnormal (benign or malignant) images. The given classification approach is applied to a database of 322 dense mammographic images, originating from the MIAS database. The results are analyzed using MATLAB.
3D Printing
This book will help you to start printing and also give an insight as to, should you even buy a printer in the first place or get your printing done by a third party. 3D Printing is not for everyone, there is a lot of doing the same thing over and over again to get it right and you will need to download and master a few other programs to enable your printing. None of this is difficult but it may not be what you were expecting. This has been updated after a further year of devolopements.
Power System Control
A large interconnected power system consists of large and small generating stations and all stations must have same frequency. The objective of providing an Automatic Generation Control (AGC) is to maintain the system frequency at nominal value and the power interchange between different areas at their scheduled values. The main requirement of an interconnected AGC is to ensure that frequency of various bus voltages and currents are maintained at near specified nominal values, tie-line power flowing among the interconnected areas are maintained at specified levels, and total power requirement on the system as a whole is shared by individual generators economically in optimum fashion.
