Educators across subject areas are striving to integrate primary sources into their pedagogy and teaching. Yet, despite their importance to authentic disciplined inquiry, the implementation of primary source activities in the pre-K–12 classroom has been limited. This lack of utilization can largely be attributed to the perception that these activities are too complex to design, implement, and grade. Many teachers also feel that primary source analysis and the construction of evidence-based narratives is too difficult for students to complete in the traditional classroom. Waring argues that this is not the case and, with this handbook, provides teacher candidates and inservice teachers with...
The number of factors implicated in the regulation of cell proliferation and differentiation is already considerable and more are continually being identified. This book concentrates on tumor necrosis factor (cachectin) and lymphotoxin, but includes observations of their interactions with other cytokines, especially the interferons and interleukins. TNF can be either cytostatic or cytotoxic to cultured cell lines, and a variety of mechanisms are proposed, ranging from DNA fragmentation to activation of phospholiopases. TNF is also reported to stimulate the growth of normal fibroblasts in vivo. The in vivo actions of TNF described here include haemorrhagic necrosis of tumors, cachexia, effects on the vasculature, and antiparasitic and antiviral activities. Also presented is some interesting data from the first stages of clinical trials of TNF as an anticancer agent.
Biologic markersâ€"indicators of biological exposure or changeâ€"offer the promise of early detection of disease caused by environmental exposure. Researchers have used these markers to discover indications of pulmonary damage from low-level ozone, a finding with serious implications for health professionals and environmental regulators. Biologic Markers in Pulmonary Toxicology is a comprehensive study of this use of biologic markers. Focusing on the respiratory tract as an entryway for airborne pollutants, this volume reviews new ways of measuring markers, the need for markers to indicate dose or exposure levels, noninvasive respiratory function tests for use with healthy humans to detect sensitivity to inhaled pollutants, approaches to evaluating markers down to the cellular and biochemical levels, and more.
Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. - Presents previously unpublished information on the discovery, development and marketing of herbicides - Includes a vital section on the origin, use, economics and fate of triazine herbicides - Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops - Establishes best management practice and environmental benefits of use in conservation tillage
