More than 1,200 sawmills produce the bulk of U.S. and Canadian softwood lumber. The maps and tables in this report show the location and size of these mills by State and Province. Analysis of timber inventories in relation to use shows a close correspondence between pricing and use intensity. In some Southern States, the intensity of use is approaching recent growth levels, but the adoption of more intensive management coupled with maturing of large areas of newly established forests should increase supply over the next two decades.

This book constitutes the refereed proceedings of the Second International Conference on Medical Image Computing and Computer-Assisted Intervention, MICCAI'99, held in Cambridge, UK, in September 1999. The 133 revised full papers presented were carefully reviewed and selected from a total of 213 full-length papers submitted. The book is divided into topical sections on data-driven segmentation, segmentation using structural models, image processing and feature detection, surfaces and shape, measurement and interpretation, spatiotemporal and diffusion tensor analysis, registration and fusion, visualization, image-guided intervention, robotic systems, and biomechanics and simulation.

The ATSDR toxicological profile succinctly characterizes the toxicology and adverse health effects information for the toxic substance described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicological properties. This public health statement tells you about pyrethrins and pyrethroids and the effects of exposure. Pyrethrum is a naturally occurring mixture of chemicals found in certain chrysanthemum flowers. Pyrethrum was first recognized as having insecticidal properties around 1800 in Asiaand was used to kill ticks and various insects such as fleas and mosquitos.

The Long Term Pavement Performance (LTPP) program has been collecting profile and International Roughness Index (IRI) information from more than 2,062 test sections since 1989 using K.J. Law 690DNC optical sensor Profilometers. Analysis of the IRI data has been limited, but with the increasing distribution of the LTPP DataPave software, this data is seeing increasing use. In an effort to confirm the quality of LTPP IRI data in the Information Management System (IMS) database and to document its variability, LTPP initiated an analysis of IRI variability in September 1997. This report documents the results of that study.
