A basic guide to the techniques and skills required to select, set up and use a scanner. Beginning with the basics, readers will learn how to prepare an image for scanning, and learn how to calculate the proper resolution for the scan. The book then moves on to more advanced subjects but all the material is presented in a jargon-free style and even the computer-illiterate will find themselves making great scans in no time at all. Illustrated throughout.
This book was developed with the goal of providing an easily understood text for those users of the scanning electron microscope (SEM) who have little or no background in the area. The SEM is routinely used to study the surface structure and chemistry of a wide range of biological and synthetic materials at the micrometer to nanometer scale. Ease-of-use, typically facile sample preparation, and straightforward image interpretation, combined with high resolution, high depth of field, and the ability to undertake microchemical and crystallographic analysis, has made scanning electron microscopy one of the most powerful and versatile techniques for characterization today. Indeed, the SEM is a vital tool for the characterization of nanostructured materials and the development of nanotechnology. However, its wide use by professionals with diverse technical backgrounds—including life science, materials science, engineering, forensics, mineralogy, etc., and in various sectors of government, industry, and academia—emphasizes the need for an introductory text providing the basics of effective SEM imaging.A Beginners’ Guide to Scanning Electron Microscopy explains instrumentation, operation, image interpretation and sample preparation in a wide ranging yet succinct and practical text, treating the essential theory of specimen-beam interaction and image formation in a manner that can be effortlessly comprehended by the novice SEM user. This book provides a concise and accessible introduction to the essentials of SEM includes a large number of illustrations specifically chosen to aid readers' understanding of key concepts highlights recent advances in instrumentation, imaging and sample preparation techniques offers examples drawn from a variety of applications that appeal to professionals from diverse backgrounds.

Get started with NMAP, OpenVAS, and Metasploit in this short book and understand how NMAP, OpenVAS, and Metasploit can be integrated with each other for greater flexibility and efficiency. You will begin by working with NMAP and ZENMAP and learning the basic scanning and enumeration process. After getting to know the differences between TCP and UDP scans, you will learn to fine tune your scans and efficiently use NMAP scripts. This will be followed by an introduction to OpenVAS vulnerability management system. You will then learn to configure OpenVAS and scan for and report vulnerabilities. The next chapter takes you on a detailed tour of Metasploit and its basic commands and configuration. You will then invoke NMAP and OpenVAS scans from Metasploit. Lastly, you will take a look at scanning services with Metasploit and get to know more about Meterpreter, an advanced, dynamically extensible payload that is extended over the network at runtime. The final part of the book concludes by pentesting a system in a real-world scenario, where you will apply the skills you have learnt. What You Will Learn Carry out basic scanning with NMAPInvoke NMAP from Python Use vulnerability scanning and reporting with OpenVAS Master common commands in Metasploit Who This Book Is For Readers new to penetration testing who would like to get a quick start on it.
In our complex times, innumerable people are stricken with disease, discomfort, and pain—some from identifiable sources and others rooted deeply in psychological trauma. More and more people are turning to natural, holistic therapies to supplement or replace traditional medicine, ease pain, and heal the source of their suffering. The Essential Guide to Energy Healing illuminates the various uses of body and earth energy to mitigate disease and suffering and helps readers judge for themselves which methods will be most effective for their ailments—or those of others they wish to heal. Practical steps show how to put these energies to use. Topics covered include: • What energy medicine is and how it works. • Magnet therapy. • Light therapy. • Cymatic (sound) therapy. • Psychic healing. • Therapeutic touch. • Healing touch. • Esoteric healing. • Qi Gong healing. • Reiki. • Pranic healing. • Crystal healing. • Distant healing.
This book is an excellent guide for you on how to use Nmap 7. The first part of the book guides you on how to get started with Nmap by installing it on the various types of operating systems. You are then guided on how to scan a network for SMB (Server Message Vulnerabilities). This will help you learn how to gather information from a target host. You are also guided on how to scan a network for the open ports. Such ports are an advantage to hackers, as they can allow them to gain unauthorized access into your network. Information encrypted with SSL/TLS encryption is prone to the heartbleed bug. You are guided to test whether your information is vulnerable to this bug. The process of determining the live hosts on a network is also explored in detail. Live hosts can be compromised for an attacker to gain valuable information from such hosts. The process of scanning a network firewall is also examined in detail. This will help you determine the ports which are open. You will also learn the services which have been assigned to the various ports on the firewall. The process of performing layer 2 discoveries with Nmap is explored in detail, thus, you will know how to do it. You are also guided on how to grab banners using Nmap. The process of gathering network information with Nmap as well as penetrating into servers is then discussed. The following topics are discussed in this book: - Getting Started with Nmap - Scanning for SMB Vulnerabilities - Scanning for Open Ports - Testing for HeartBleed Bug - Detecting Live Hosts - Firewall Scanning - Performing Layer 2 Discovery - Banner Grabbing - Information Gathering - Penetrating into Servers

This new and improved 4th Edition of Don Ridgway?s unabashedly practical and famously unique how-to guide to vascular scanning will astound and delight both beginners and veterans who are cross-training in vascular ultrasound. Like previous editions, this one contains all of the features that have made this book so popular and useful.\\In this first all-color edition, the emphasis is on showing, not just telling: You will find dozens of new full-color technical and anatomic illustrations; 150+ duplex scans, color flow images, and Doppler waveforms; and scores of schematics, cross-sections, ultrasound images, and photographs?more than 700 illustrations in all. As praise for the previous editions suggests, you won?t find anything else like this guide for the relative novice: extremely reader-friendly, lavishly illustrated, and focused squarely on the real-world skill-building needs of both budding vascular sonographers and seasoned veterans.\\ As a welcome bonus, the 18-credit CME quiz at the end of the book can be combined with any of Davies? other 12-credit CME activities to help busy sonographers meet their ARDMS triennium requirements in two easy steps.
