Phytotoxicity of Nanoparticles

by Mohammad Faisal Quaiser Saquib Abdulrahman A. Alatar Abdulaziz A. Al-Khedhairy

This book provides relevant findings on nanoparticles’ toxicity, their uptake, translocation and mechanisms of interaction with plants at cellular and sub-cellular level. The small size and large specific surface area of nanoparticles endow them with high chemical reactivity and intrinsic toxicity. Such unique physicochemical properties draw global attention of scientists to study potential risks and adverse effects of nanoparticles in the environment. Their toxicity has pronounced effects and consequences for plants and ultimately the whole ecosystem. Plants growing in nanomaterials-polluted sites may exhibit altered metabolism, growth reduction, and lower biomass production. Nanoparticles can adhere to plant roots and exert physicochemical toxicity and subsequently cell death in plants. On the other hand, plants have developed various defense mechanisms against this induced toxicity. This books discusses recent findings as well as several unresolved issues and challenges regarding the interaction and biological effects of nanoparticles. Only detailed studies of these processes and mechanisms will allow researchers to understand the complex plant-nanomaterial interactions.

Picking Up: On the Streets and Behind the Trucks with the Sanitation Workers of New York City

by Robin Nagle

A “gripping” behind-the-scenes look at New York’s sanitation workers by an anthropologist who joined the force (Robert Sullivan, author of Rats).America’s largest city generates garbage in torrents—11,000 tons from households each day on average. But New Yorkers don’t give it much attention. They leave their trash on the curb or drop it in a litter basket, and promptly forget about it. And why not? On a schedule so regular you could almost set your watch by it, someone always comes to take it away.But who, exactly, is that someone? And why is he—or she—so unknown?In Picking Up, the anthropologist Robin Nagle introduces us to the men and women of New York City’s Department of Sanitation and makes clear why this small army of uniformed workers is the most important labor force on the streets. Seeking to understand every aspect of the Department’s mission, Nagle accompanied crews on their routes, questioned supervisors and commissioners, and listened to story after story about blizzards, hazardous wastes, and the insults of everyday New Yorkers. But the more time she spent with the DSNY, the more Nagle realized that observing wasn’t quite enough—so she joined the force herself. Driving the hulking trucks, she obtained an insider’s perspective on the complex kinships, arcane rules, and obscure lingo unique to the realm of sanitation workers.Nagle chronicles New York City’s four-hundred-year struggle with trash, and traces the city’s waste-management efforts from a time when filth overwhelmed the streets to the far more rigorous practices of today, when the Big Apple is as clean as it’s ever been.“An intimate look at the mostly male work force as they risk injury and endure insult while doing the city’s dirty work [and] a fascinating capsule history of the department.” —Publishers Weekly“[Nagle’s] passion for the subject really comes to life.” —The New York Times“Evokes the physical and psychological toll of this dangerous, filthy, necessary work.” —Nature“Nagle joins the likes of Jane Jacobs and Jacob Riis, writers with the chutzpah to dig deep into the Rube Goldberg machine we call the Big Apple and emerge with a lyrical, clear-eyed look at how it works.” — Mother Jones

Each chapter has specialist authorship and ideas clearly characterized from both academic and industrial viewpoints. PID Control in the Third Millennium is of interest to academics requiring a reference for the current state of PID-related research and a stimulus for further inquiry. Industrial practitioners and manufacturers of control systems with application problems relating to PID will find this to be a practical source of appropriate and advanced solutions.

PID Controller Tuning Using the Magnitude Optimum Criterion

by Konstantinos G. Papadopoulos

An instructive reference that will help control researchers and engineers, interested in a variety of industrial processes, to take advantage of a powerful tuning method for the ever-popular PID control paradigm. This monograph presents explicit PID tuning rules for linear control loops regardless of process complexity. It shows the reader how such loops achieve zero steady-position, velocity, and acceleration errors and are thus able to track fast reference signals. The theoretical development takes place in the frequency domain by introducing a general-transfer-function-known process model and by exploiting the principle of the magnitude optimum criterion. It is paralleled by the presentation of real industrial control loops used in electric motor drives. The application of the proposed tuning rules to a large class of processes shows that irrespective of the complexity of the controlled process the shape of the step and frequency response of the control loop exhibits a specific performance. This specific performance, along with the PID explicit solution, formulates the basis for developing an automatic tuning method for the PID controller parameters which is a problem often met in many industry applications--temperature, pH, and humidity control, ratio control in product blending, and boiler-drum level control, for example. The process of the model is considered unknown and controller parameters are tuned automatically such that the aforementioned performance is achieved. The potential both for the explicit tuning rules and the automatic tuning method is demonstrated using several examples for benchmark process models recurring frequently in many industry applications.

PID Tuning: A Modern Approach via the Weighted Sensitivity Problem

by Salvador Alcántara Cano Ramon Vilanova Arbós Carles Pedret i Ferré

The PID controller is the most common option in the realm of control applications and is dominant in the process control industry. Among the related analytical methods, Internal Model Control (IMC) has gained remarkable industrial acceptance due to its robust nature and good set-point responses. However, the traditional application of IMC results in poor load disturbance rejection for lag-dominant and integrating plants. This book presents an IMC-like design method which avoids this common pitfall and is devised to work well for plants of modest complexity, for which analytical PID tuning is plausible. For simplicity, the design only focuses on the closed-loop sensitivity function, including formulations for the H∞ and H2 norms. Aimed at graduate students and researchers in control engineering, this book: Considers both the robustness/performance and the servo/regulation trade-offs Presents a systematic, optimization-based approach, ultimately leading to well-motivated, model-based, and analytically derived tuning rules Shows how to tune PID controllers in a unified way, encompassing stable, integrating, and unstable processes Finds in the Weighted Sensitivity Problem the sweet spot of robust, optimal, and PID control Provides a common analytical framework that generalizes existing tuning proposals

Piezo-Active Composites

by Vitaly Yu. Topolov Paolo Bisegna Christopher R. Bowen

The book is devoted to the problem of microgeometry properties and anisotropy relations in modern piezo-active composites. These materials are characterized by various electromechanical properties and remarkable abilities to convert mechanical energy into electric energy and vice versa. Advantages of the performance of the composites are discussed in the context of the orientation effects, first studied by the authors for main connectivity patterns and with due regard to a large anisotropy of effective piezoelectric coefficients and electromechanical coupling factors. The novelty of the book consists in the systematization results of orientation effects, the anisotropy of piezoelectric properties and their role in forming considerable hydrostatic piezoelectric coefficients, electromechanical coupling factors and other parameters in the composites based on either ferroelectric ceramic or relaxor-ferroelectric single crystals.
