The bestselling reference on environmental microbiology—now in a new edition This is the long-awaited and much-anticipated revision of the bestselling text and reference. Based on the latest information and investigative techniques from molecular biology and genetics, this Second Edition offers an in-depth examination of the role of microbiological processes related to environmental deterioration with an emphasis on the detection and control of environmental contaminants. Its goal is to further our understanding of the complex microbial processes underlying environmental degradation, its detection and control, and ultimately, its prevention. Features new to this edition include: A complete...
Despite the perception that artworks are timeless and unchanging, they are actually subject to biological attack from a variety of sources--from bacteria to fungi to insects. This groundbreaking volume, which publishes the proceedings of a conference held at The Metropolitan Museum of Art in 2002, explores how the development of these organisms can be arrested while preserving both the work of art and the health of the conservator.The richly illustrated text, containing the writings of over 40 scientists and conservators, is divided into sections on stone and mural paintings, paper, textiles, wood and archaeological materials, treatment and prevention, and special topics. The artworks and cultural properties discussed include, among many others, Paleolithic cave paintings, Tiffany drawings, huts built by early Antarctic explorers, and a collection of toothbrushes taken from Auschwitz victims.
Examines the application of scientific methods to the study and conservation of art and cultural properties. This work addresses scientific topics of broad interest, cutting across the boundaries of traditional disciplines and attracting up to 250 leadingresearchers in the field.

In the twenty-first century, expecting parents are inundated with information and advice from every direction, but are often strapped for perspective on how to think through it. Unlike traditional pregnancy guidebooks that offer recommendations, Carrying On helps expecting parents make sense of the overwhelming amount of counsel available to them by shedding light on where it all came from. How and why did such confusing and contradictory guidance on pregnancy come to exist? Carrying On investigates the origin stories of prevailing prenatal health norms by exploring the evolution of issues at the center of pregnancy, ranging from morning sickness and weight gain to ultrasounds and induction....
In eukaryotes, small nuclear RNAs (snRNAs) are required for pre-mRNA splicing. Most snRNAs, such as U1, U2, U4, and U5 are synthesized by RNA polymerase II, but U6 snRNA is synthesized by RNA polymerase III. Transcription of snRNA genes by either RNA polymerase is dependent upon a proximal sequence element (PSE) located upstream of position −40 relative to the transcription start site. In the insect Drosophila melanogaster, the PSE is referred to more specifically as the PSEA to distinguish it from a second conserved element termed the PSEB. Chapter 1 describes the identification and cloning of the genes that code for three polypeptide subunits of the Drosophila melanogaster PSEA-binding p...
