Most Perl programmers were originally trained as C and Unix programmers, so the Perl programs that they write bear a strong resemblance to C programs. However, Perl incorporates many features that have their roots in other languages such as Lisp. These advanced features are not well understood and are rarely used by most Perl programmers, but they are very powerful. They can automate tasks in everyday programming that are difficult to solve in any other way. One of the most powerful of these techniques is writing functions that manufacture or modify other functions. For example, instead of writing ten similar functions, a programmer can write a general pattern or framework that can then create the functions as needed according to the pattern. For several years Mark Jason Dominus has worked to apply functional programming techniques to Perl. Now Mark brings these flexible programming methods that he has successfully taught in numerous tutorials and training sessions to a wider audience.

* Introduces powerful programming methods—new to most Perl programmers—that were previously the domain of computer scientists
* Gradually builds up confidence by describing techniques of progressive sophistication
* Shows how to improve everyday programs and includes numerous engaging code examples to illustrate the methods

The Chinese Research Academy of Environmental Sciences (CRAES) has conducted the Environmental exposure related activity pattern research of Chinese population (Adults). Exposure Factors Handbook of Chinese Population (Adults) was compiled based on the results from this study.

Highlights of the Chinese Exposure Factors Handbook is a brief introduction to the content of Exposure Factors Handbook of Chinese Population (Adults). In each chapter, definitions, possible influence factors, and survey methods have been introduced, followed by recommended values for urban/rural areas, different genders, age groups and regions with information of mean, median and P5, P25, P75, P95 values.

With the abundant data and tables, readers are provided with an accessible and comprehensive overview of Chinese exposure factors.

• The first and only one covering Chinese exposure factors, which have been absent until now and are essential for the exposure and risk assessment of environmental agents
• Presents several tables on ingestion rates, as well as activity biology and residential factors based on data from a national survey
• Provides a brief but comprehensive understanding of the environmental exposure-related factors for the Chinese population

Highway Bridge Maintenance Planning and Scheduling provides new tactics for highway departments around the world that are faced with the dilemma of providing improved operations on a shoestring budget. Even after the much needed infrastructure funding is received, the question of which project comes first must be answered. Written by a 20-year veteran with the Kansas Department Of Transportation Bridge Office in design and in maintenance, this book provides Senior Bridge Maintenance Engineers with practical advice on how to create an effective maintenance program that will allow them to not only plan, schedule, direct, and monitor highway bridge repair and rehabilitation projects, but also evaluate all completed work for technical acceptability, productivity, and unit-cost standards.

• Provides the tools and methods for building, maintaining, planning, and scheduling effective maintenance
• Presents experience-based suggestions for evaluating highway bridges to determine maintenance priorities
• Includes methods for evaluating all completed work for technical acceptability, productivity, and unit-cost standards

This book helps readers maximize effectiveness in all facets of highway engineering including planning, design, operations, safety, and geotechnical engineering. Highway Engineering: Planning, Design, and Operations features a seven part treatment, beginning with a clear and rigorous exposition of highway engineering concepts.  These include project development, and the relationship between planning, operations, safety, and highway types (functional classification). Planning concepts and a four-step process overview are covered, along with trip generation, equations versus rates, trip distribution, and shortest path models equations versus rates. This is followed by parts concerning applications for horizontal and vertical alignment, highway geometric design, traffic operations, traffic safety, and civil engineering topics.

• Covers traffic flow relationships and traffic impact analysis, collision analysis, road safety audits, advisory speeds
• Applications for horizontal and vertical alignment, highway geometric design, traffic operations, traffic safety, civil engineering topics
• Engineering considerations for highway planning design and construction are included, such as hydraulics, geotechnical engineering, and structural engineering

Histocampatibility covers the genetic, immunologic, and the chemical studies on allograft rejection process. The book is composed of 13 chapters that describe how these studies relate to medicine, organ transplantation in man, basic immunology, cell membrane structures, and cancer research.
After briefly dealing with the early studies on isografts and allografts in laboratory animals, the book describes the histogenetic methods of gene manipulation and transplantation that permit identification of individual histocompatibility loci. The following chapter examines the significance of congenic resistant lines in determining the diversity of histocompatibility loci and allele and immune response genes. Other chapters present immunogenetic and serological methods, as well as the applications of these methods in studying alloantigens and H-2 complex loci and of immunogenetic methods to human. The book also discusses the practical implication of HLA immunogenetics in organ transplantation and describes the biochemical, immunochemical, and dynamic properties of alloantigens. A chapter discusses the associations between HLA system and disease and the various mechanisms that have been suggested to explain these associations. The last chapter focuses on allograft reaction and on established facts of cellular immunity.
This book is a valuable source of information for researchers in the fields of medicine, organ transplantation in man, basic immunology, cell membrane structures, and cancer.

This volume, Toxicology in Antiquity II, continues to tell the story of the roots of toxicology in ancient times. Readers learn that before scientific research methods were developed, toxicology thrived as a very practical discipline. Toxicologists are particularly proud of the rich and storied history of their field and there are few resources available that cover the discipline from a historical perspective. People living in ancient civilizations readily learned to distinguish safe from hazardous substances, how to avoid these hazardous substances and how to use them to inflict harm on enemies. Volume II explores the use of poison as weapons in war and assassinations, early instances of air pollution, the use of hallucinogens and entheogens, and the role of the snake in ancient toxicology.

• Provides the historical background for understanding modern toxicology
• Illustrates the ways ancient civilizations learned to distinguish safe from hazardous substances, how to avoid the hazardous substances and how to use them against enemies
• Details scholars who compiled compendia of toxic agents
