The iris is a circular, pigmented tissue that separates the anterior chamber of the eye from the posterior chamber. It has a crucial role on controlling the amount of the light entering the eye through its central opening “the pupil". The Iris has multiple important functions that support and provide image clarity on the retina. However, it is a largely neglected part of the eye, compared to the cornea lens, retina, and optic nerve, and has not been focused on in a comprehensive way until now. The Iris: Understanding the Essentials, combines different aspects of scientific information from a variety of fields, such as anatomy, histopathology, molecular biology, electron microscopy and othe...
This book brings together concepts from the building, environmental, behavioural and health sciences to provide an interdisciplinary understanding of office and workplace design. Today, with changes in the world of work and the relentless surge in technology, offices have emerged as the repositories of organizational symbolism, denoted by the spatial design of offices, physical settings and the built environment (architecture, urban locale). Drawing on Euclidian geometry that quantifies space as the distance between two or more points, a body of knowledge on office buildings, the concept of office and office space, and the interrelationships of spatial and behavioural attributes in office de...
Chronic ethylbenzene exposures and attendant potential health risks for United States children and prospective parents were first evaluated under the United States Environmental Protection Agency’s Voluntary Children’s Chemical Evaluation Program. Using updated data and methods, a 2015 reevaluation observed declines in ethylbenzene releases and concentrations in ambient and indoor air. Both assessments identified inhalation as the dominant exposure route and smoking as the greatest contributor, with dietary intake much lower. Children’s exposure concentrations were similar to that of adults, but their intakes were higher. Neither breastfeeding nor toy mouthing was a significant source....
The development of vertebrate muscle has long been a major area of research in developmental biology. During the last decade, novel technical approaches have allowed us to unravel to a large extent the mechanisms underlying muscle formation, and myogenesis has become one of the best-understood paradigms for cellular differentiation. This book concisely summarizes our current knowledge about muscle development in vertebrates, from the determination of muscle precursors to terminal differentiation. Each chapter has been written by an expert in the field, and particular emphasis has been placed on the different developmental and molecular pathways followed by the three types of vertebrate musculature - skeletal, heart and smooth muscle.
Covers receipts and expenditures of appropriations and other funds.
This book examines the context, motivation and current status of biometric systems based on the palmprint, with a specific focus on touchless and less-constrained systems. It covers new technologies in this rapidly evolving field and is one of the first comprehensive books on palmprint recognition systems. It discusses the research literature and the most relevant industrial applications of palmprint biometrics, including the low-cost solutions based on webcams. The steps of biometric recognition are described in detail, including acquisition setups, algorithms, and evaluation procedures. Constraints and limitations of current palmprint recognition systems are analyzed and discussed. The aut...
Cystic Fibrosis has seen dramatic advances in treatment since the last edition, including targeted cystic fibrosis transmembrane conductance regulator (CFTR) protein modulators for most CFTR gene abnormalities. This new fifth edition is an update and expansion of the rapid clinical and scientific advances in improving prognosis, and the impact of COVID-19, all of which has transformed conventional models of care. It covers basic science, such as how detailed understanding of the biology of the CFTR gene and protein has led to novel and beneficial therapies, as well as all aspects of clinical management in high-, middle- and low-income settings and the voices of individuals with CF from acros...
