Book Description
This publication presents a harmonized approach to quality assurance in the field of computed tomography applied to both diagnostics and therapy. It gives a careful analysis of the principles and specific instructions that can be used for a quality assurance programme for optimal performance and reduced patient dose in diagnostic radiology. In some cases, radiotherapy programmes are making a transition from 2-D to 3-D radiotherapy, a complex process which critically depends on accurate treatment planning. In this respect, the authors also provide detailed information about the elements needed for quality assurance testing, including those relating to accurate patient characterization as needed for radiotherapy treatment planning.

Book Description
This publication addresses recent developments in neutron generator (NG) technology. It presents information on compact instruments with high neutron yield to be used for neutron activation analysis (NAA) and prompt gamma neutron activation analysis in combination with high count rate spectrometers. Traditional NGs have been shown to be effective for applications including borehole logging, homeland security, nuclear medicine and the on-line analysis of aluminium, coal and cement. Pulsed fast thermal neutron analysis, as well as tagged and timed neutron analysis, are additional techniques which can be applied using NG. Furthermore, NG can effectively be used for elemental analysis and is also effective for analysis of hidden materials by neutron radiography. Useful guidelines for developing NG based research laboratories are also provided in this publication.

Book Description
Introduction to Computer Security draws upon Bishop's widely praised Computer Security: Art and Science, without the highly complex and mathematical coverage that most undergraduate students would find difficult or unnecessary. The result: the field's most concise, accessible, and useful introduction. Matt Bishop thoroughly introduces fundamental techniques and principles for modeling and analyzing security. Readers learn how to express security requirements, translate requirements into policies, implement mechanisms that enforce policy, and ensure that policies are effective. Along the way, the author explains how failures may be exploited by attackers--and how attacks may be discovered, understood, and countered. Supplements available including slides and solutions.

Book Description
The book provides an excellent review of all the clinical aspects of neuroanesthesia in children, including neurosurgeries during fetal state to neonatal, infancy, toddler, and school-going age groups. To provide optimal anesthetic care in children undergoing neurosurgery, the care provider must have adequate knowledge on the developing brain and spinal cord, and the effect of anesthetics on the neuronal tissue, and the inherent issues pertaining to neurologic lesions. This book covers the diagnostic, imaging, surgical as well as anesthetic managements of all the neurosurgical problems in children. The chapters include a wide range of topics from basic neurophysiology to general concerns for pediatric neuroanesthesia, including fluid management, blood transfusion, temperature regulation, and surgical positioning, as well as specific issues such as anesthesia for brain tumor surgery, hydrocephalus, neural tube defects, cerebrovascular surgeries such as aneurysmal surgery, arteriovenous malformations (AVMs), Moyamoya disease, and vein of Galen malformation, functional neurosurgery, epilepsy surgery, neuroendoscopy, craniovertebral junction anomalies, spinal surgeries, neurotrauma, and brain abscess with congenital heart diseases. Interesting topics like neuroanesthesia in remote locations, regional anesthesia during neurosurgery, and anesthesia for children with neuromuscular disease are also discussed. Moreover, the book elaborates on advanced neuroanesthesia techniques during fetal neurosurgery and craniopagus separation surgery; and the postoperative intensive care management aspects in each chapter. It is supplemented with figures depicting surgical procedures and positioning, neuroimages, tables and illustrations for easy understanding. This book caters to neuroanesthesiologists, pediatric anesthesiologists, residents, and fellows of anesthesia or neuroanesthesia, practicing anesthesiologists, pediatric neurointensivists, nurse anesthetists, neurosurgeons, and pediatric neurosurgeons. It also serves as a reference book for the DM (neuroanesthesiology and neurocritical care), DNB-SS (neuroanesthesiology), and MD (anesthesiology) curriculums apart from anesthesia residency and pediatric anesthesia/ neurosurgery fellowship programs offered at various Institutions worldwide.

Book Description
The measurement of food consumption and expenditure is a fundamental component of any analysis of poverty and food security, and hence the importance and timeliness of devoting attention to the topic cannot be overemphasized as the international development community confronts the challenges of monitoring progress in implementing the 2030 Agenda for Sustainable Development. In 2014, the International Household Survey Network published a desk review of the reliability and relevance of survey questions as included in 100 household surveys from low- and middle-income countries. The report was presented in March 2014 at the forty-fifth session of the United Nations Statistical Commission (UNSC), in a seminar organized by the Inter-Agency and Expert Group on Food Security, Agricultural and Rural Statistics (IAEG-AG). The assessment painted a bleak picture in terms of heterogeneity in survey design and overall relevance and reliability of the data being collected. On the positive side, it pointed to many areas in which even marginal changes to survey and questionnaire design could lead to a significant increase in reliability and consequently, great improvements in measurement accuracy. The report, which sparked a lot of interest from development partners and UNSC member countries, prompted IAEG-AG to pursue this area of work with the ultimate objective of developing, validating, and promoting scalable standards for the measurement of food consumption in household surveys. The work started with an expert workshop that took place in Rome in November 2014. Successive versions of the guidelines were drafted and discussed at various IAEG-AG meetings, and in another expert workshop organized in November 2016 in Rome. The guidelines were put together by a joint FAO-World Bank team, with inputs and comments received from representatives of national statistical offices, international organizations, survey practitioners, academics, and experts in different disciplines (statistics, economics, nutrition, food security, and analysis). A list of the main contributors is included in the acknowledgment section. In December 2017 a draft of the guidelines was circulated to 148 National Statistical Offices from low- to high-income countries for comments. The document was revised following that consultation and submitted to UNSC, which endorsed it at its forty-ninth session in March 2018 (under item 3(j) of the agenda, agricultural and rural statistics. The version presented here reflects what was endorsed by the Commission, edited for language. The process received support from the Global Strategy for Agricultural and Rural Statistics. The document is intended to be a reference document for National Statistical Offices, survey practitioners, and national and international agencies designing household surveys that involve the collection of food consumption and expenditure data.

Book Description
This publication supports an interim solution to the dosimetric problems caused by modern computed tomography (CT) equipment, particular with respect to the wide X ray beam angles increasing seen in clinical practice. It reviews the development of current CT dose formalisms up to the current International Electrotechnical Commission (IEC) methodologies and presents practical measurement guidance in the implementation of new dosimetric methods needed with wide beam CT. Additional items of discussions are current approaches of the American Association of Physicists in Medicine in the USA to CT dosimetry as well as calibration aspects of CT dosimetric instrumentation. A summary describes the present status of CT dosimetry and provides recommendations for future action.
