ggf. zzgl. Versand

This book presents reviews, examples and case studies of innovative applications in solid and hazardous waste management. The economics of waste management have since become a significant research area in their own right, and two chapters address these issues. In addition, dedicated chapters cover specific categories of waste such as biomedical and institutional waste, plastics and e-waste. The book subsequently discusses newer analytical methods like SEM, EDX, XRD and optical microscopy, along with selected “older” methods for sampling and characterizing different types of waste. The various applications of mathematical tools like linear optimization, various software/models like WISCLeach, and DRASTIC, and tools like remote sensing and GIS are illustrated in many of the chapters. Lastly, since composting is one of the most popular treatment methods for managing the organic component of municipal solid waste, the book provides an overview of composting and the fundamentals of microbiology that are essential to understanding waste-related biological processes. The book was primarily written for students and practitioners in the field who are already familiar with the basics. All chapters were prepared by practicing experts and scholars in the field, and are intended to help readers better understand and apply these principles and practices in their own endeavours. Key topics covered in the book:   •  The circular economy and the economics of solid waste management •  Various remote sensing and GIS applications for managing municipal solid waste, coal fires in mines, changes in land use and land cover in industrial areas, etc. •  Treatment and management of different types of solid waste: institutional (including biomedical), residential, e-waste, plastic, and ash from thermal power plants •   Sampling and characterization of municipal waste and compost •   Fundamentals of microbiology •   Overview of environmental regulations, especially those pertaining to solid and hazardous waste management

In present study, Light weight Expanded Clay Aggregate (LECA) coated with iron (Fe) oxide has been explored as a green and low cost sorbent to remove Ni (II) from polluted water. Iron Oxide Coated LECA (IOCL) as a new sorbent was examined for its efficiency as Ni (II) sorbent by change the operational parameters, such as contact time, initial pH of the solutions, sorbent dosages and initial Ni (II) concentration in batch systems. Also the adsorption characteristics of Natural LECA (NL) and IOCL were examined trough X-ray Fluorescence Spectroscopy (XRF), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy analysis. Results revealed that modified sorbent have a rougher surface with holes and cave type opening on the surface, which state high porosity and favorable surface area for adsorption process. The surface area increased due to coating process. The results obtained from Design-Expert software indicate that a IOCL dosage of 5.0 g.L-1, initial solution pH of 6.2 and initial Ni (II) concentration of 50.0 mg.L-1 in contact time of 2 h, has the optimum condition for removal of Ni (II) in domain of experiments.

With the development of technology and industries, newer materials such as Tungsten, Molybdenum etc. and various other Super Alloys and Ceramics have been developed which are being widely used in nuclear engineering, aerospace and various other industries because of their hardness, heat resistance qualities and high strength to weight ratio. Machining of these hard materials is very difficult by conventional machining processes. Therefore non-conventional machining processes have been developed for the machining of such type of materials. The Objective of this work is mainly to study the effect of various input parameters like Electrode material, Discharge Current, Gap Voltage, Pulse-On Time, Pulse-Off Time on the various output parameters like MRR, TWR and Surface roughness. In this study, these output parameters are studied by using the Taguchi's Design of Experiments through Minitab software. Using this software, Means and S/N ratios for all the output parameters were calculated. Micro structure was also observed using SEM machine.

Nano LaAlO3 & Simulation Comparisons of High K ...
54,90 € *
ggf. zzgl. Versand

The continued scaling of CMOS transistor requires replacement of the conventional silica gate oxide (SiO2) with a higher dielectric constant (K) gate dielectric to minimize the leakage current and to maintain a high capacitance especially at nano level to escape Quantum Mechanical Tunneling. Among many contenders, La2O3 is believed to be the suitable successor but the lanthanide oxides are known to be hygroscopic, which can affect their dielectric quality. Hence, we present a work on mixing the lanthanum oxide (or lanthana) with a less hygroscopic oxide such as Al2O3 to stabilize the insulator layer. Lanthanum Aluminate (LaAlO3) is much less susceptible to moisture. It also combines the advantages of the high dielectric constant of La2O3 and the chemical and thermal stability of Al2O3. Synthesis of Lanthanum Aluminate nano particles is done by Gelation-Precipitation method and are characterized by XRD, PSA, UV-Vis, TG/DTA, SEM, TEM and LCR-meter. The SiO2, La2O3, LaAlO3 are simulated, the reduction in leakage current of MOSFET using nano Silica, nano Lanthana and nano Lanthanum Aluminate insulator is studied using Quantum Wise-Virtual Nano Lab and Nextnano software tools.

The genus Trichoderma contains species that are of great economic importance due to their ability to act as biological control agents against a large variety of fungal plant pathogens. In the present investigation eight isolates of the Trichoderma sp. were obtained from the rhizosphere soils of Bharuch and Narmada districts of Gujarat (India). The isolates were characterized on the basis of their cultural, morphological, and molecular characteristics. SEM was used to study the presence of conidiophores, phialides, and conidia. These isolates were studied using Randomly Amplified Polymorphic DNA (RAPD) for genetic diversity. A total number of 101 reproducible polymorphic bands were obtained using 9 random primers. The data were subjected to numerical analysis using NTSYS software and genetic distance between each isolate was calculated. Cluster analysis was used to generate a dendrogram showing the relationship among them. RAPD profile showed the genetic diversity among the eight isolates with the formation of three clusters T. harzianum, T. viride and T. longibrachiatum.

ggf. zzgl. Versand

In this book, authors Tenko Raykov and George A. Marcoulides introduce students to the basics of structural equation modeling (SEM) through a conceptual, nonmathematical approach. For ease of understanding, the few mathematical formulas presented are used in a conceptual or illustrative nature, rather than a computational one. Featuring examples from EQS, LISREL, and Mplus, A First Course in Structural Equation Modeling is an excellent beginner's guide to learning how to set up input files to fit the most commonly used types of structural equation models with these programs. The basic ideas and methods for conducting SEM are independent of any particular software. Highlights of the Second Edition include: . Review of latent change (growth) analysis models at an introductory level . Coverage of the popular Mplus program . Updated examples of LISREL and EQS . A CD that contains all of the text's LISREL, EQS, and Mplus examples. A First Course in Structural Equation Modeling is intended as an introductory book for students and researchers in psychology, education, business, medicine, and other applied social, behavioral, and health sciences with limited or no previous exposure to SEM. A prerequisite of basic statistics through regression analysis is recommended. The book frequently draws parallels between SEM and regression, making this prior knowledge helpful.

Informationsverarbeitung (IV) hat die organisatorischen und betrieblichen Ab laufe in Wirtschaft und Verwaltung bereits so stark durchdrungen, daB ihr Still stand oder eine Fehlfunktion unmittelbar gravierende Probleme hervorrufen. Zum ordnungsgemiiBen Einsatz der IV gehoren nicht nur funktionierende technische und insbesondere Software-Systeme, sondern auch die verstiindnisvolle Handha bung der IV durch Fiihrungskriifte und Sachbearbeiter, also durch die Anwender, und ihre aktive Obernahme von Verantwortung bei Konzeption und Budgetierung neuer IV-Vorhaben. Dazu brauchen sie ein tragfiihiges Grundwissen iiber die Mog lichkeiten der IV und iiber den Zusammenhang zwischen IV und Organisation. Dieses Grundwissen zu vermitteln, haben wir uns zum Ziel gesetzt. Das Adjektiv 'innovativ' im Titelleitet sich aus zwei Merkmalen her, die in die sem Lexikon besonders beriicksichtigt werden: I. Die IV durchliiuft gerade einen dritten Innovationsschritt. Schritt eins umfaBte in den 60er und 70er Jahren die Einfiihrung zentraler Verfahren auf GroBrechnern und Rechnern der mittleren Datentechnik. Schritt zwei fiihrte in den 80er Jahren zu bildschirmgestiitzten Online-Verfahren und zum Ersatz der klassischen Bild schirme durch integrierte PCs. Der aktuelle dritte Schritt wird sowohl zur organi sationsweiten Integration der IV-gestiitzten Anwendungen in Wirtschaft und Ver waltung fUhren als auch zur Nutzung weltweiter Netze, iiber die man he ute meist als Data Highway oder Datenautobahn spricht. Damit werden auch die privaten Haushalte vernetzt, was sowohl zur privaten Nutzung als auch zur Verstiirkung von Heimarbeit fUhren wird. 1m Zuge dieser Entwicklung werden auch Telefon, PC und Television immer enger zusammenwachsen. 2.

Heat and Mass Transfer in Urea Prilling Process
49,00 € *
ggf. zzgl. Versand

Urea prills are produced in the prilling tower, where a cooling-solidification-cooling process of the prills takes place. The ambient air is used as the cooling stream for this process. A case study of the urea prilling process is chosen due to in hot/humid days, the temperature of the product at the bottom of the prilling tower is hot and cannot be packed directly. In addition, the urea prills form lumps and cakes with each other on the scrubber at the bottom of the prilling tower that affects the quality of the product. A mathematical model based on the particle kinematics,and, heat and mass transfer between the urea prills and the cooling air is developed. This is followed by using a numerical technique with an explicit scheme to solve the model. The model numerical results are validated with Scanning Electronic Microscope (SEM) observation of urea particles. Moreover,to investigate the effect of the urea prilling tower configuration parameters on the above urea product problems, the hydrodynamic of air flow inside the tower is analyzed using Computational Fluid Dynamics (CFD) simulation software.
