This volume integrates the latest findings on earliest life forms, identified and characterised in some of the oldest rocks on Earth. New material from prominent researchers in the field is presented and evaluated in the context of previous work. Emphasis is placed on the integration of analytical methods with observational techniques and experimental simulations. The opening section focuses on submarine hot springs that the majority of researchers postulates served as the cradle of life on Earth. In subsequent sections, evidence for life in strongly metamorphosed rocks such as those in Greenland is evaluated and early ecosystems identified in the well preserved Barberton and Pilbara successions in Southern Africa and Western Australia. The final section includes a number of contributions from authors with alternate perspectives on the evidence and record of early life on Earth. Audience This volume will be valuable to researchers and graduate students in biogeosciences, geochemistry, paleontology and geology interested in the origin of life on earth.

Coalbed gas has been considered a hazard since the early 19th century when the first mine gas explosions occurred in the United States in 1810 and France in 1845. In eastern Australia methane-related mine disasters occurred late in the 19th century with hundreds of lives lost in New South Wales, and as recently as 1995 in Queensland's Bowen Basin. Ventilation and gas drainage technologies are now in practice. However, coalbed methane recently is becoming more recognized as a potential source of energy; rather than emitting this gas to the atmosphere during drainage of gassy mines it can be captured and utilized. Both economic and environmental concerns have sparked this impetus to capture coalbed methane. The number of methane utilization projects has increased in the United States in recent years as a result, to a large extent, of development in technology in methane recovery from coal seams. Between 1994 and 1997, the number of mines in Alabama, Colorado, Ohio, Pennsylvania, Virginia, and West Virginia recovering and utilizing methane increased from 1 0 to 17. The Environmental Protection Agency estimates that close to 49 billion cubic feet (Bet) of methane was recovered in 1996, meaning that this amount was not released into the atmosphere. It is estimated that in the same year total emissions of methane equaled 45. 7 Bcf. Other coal mines are being investigated at present, many ofwhich appear to be promising for the development of cost-effective gas recovery.

Preclinical research related to mood and anxiety disorders relies extensively upon mouse behavioral tests and models, the use of which continues to increase as a greater number of underlying susceptibility genes are discovered, new targets for medications are identified, and clinical studies reveal novel neurobiological risk factors. Mood and Anxiety Related Phenotypes in Mice: Characterization Using Behavioral Tests, Volume II serves as a complement to the previous volume in order to offer a comprehensive resource for the behavioral approaches that are valuable for the characterization of mood and anxiety disorder-related behaviors in mice and the techniques that are utilized in the development of effective medications. As a collection presented in the Neuromethods series, each chapter provides a brief background and review of the test or model as well as a complete and up-to-date protocol narrative. Authoritative and comprehensive, Mood and Anxiety Related Phenotypes in Mice: Characterization Using Behavioral Tests, Volume II is an ideal resource for scientists actively pursuing or interested in establishing vital behavioral protocols in their laboratories.

This new edition of one of the BSAVA's most popular Manuals has been extensively revised, drawing on the expertise of a predominantly new roster of authors. The Manual focuses on common ophthalmic conditions in dogs and cats, structured into examination and clinical techniques; diagnosis and treatment of common ocular diseases, and a problem-oriented approach to common clinical presentations. The Manual provides an accessible source of practical information for general practitioners, veterinary students, nurses and technicians, and will also be a useful resource for those working toward specialist qualifications.

The Golden Age of Ironwork, by Henry Jonas Magaziner, covers ironwork from roughly 1840 to 1930. Thus, it includes cast iron, which prevailed during the nineteenth century and hand wrought iron, which triumphed from about 1900 to 1930. With 173 photographs by Robert Golden the books describes this golden period. There are also a few examples of contemporary ironwork

"irreverent, smart, and funny" God "I LOL'd." Jesus ------------------------------------- The Fates are missing and all the gods are running amok. Existential Investigator Valentine Ryan wants nothing more than to be left alone with his scotch, but as a roster of friends, enemies, frenemies, and wilding gods make clear, he really has no choice but to go looking for the errant immortals. With a cocktail in hand and a quip on his lips, Ryan wrangles gods, battles gangsters, woos a goddess, fights his demons, and maybe saves the world. The story ends with death, but it starts with a dame. Because it always starts with a dame.

The Carpenter's And Builder's Assistant, And Wood Worker's Guide, BY LUCIUS D. GOULD. PREFACE. Several years have elapsed since I first published the House Carpenters Assistant, which met with a ready sale of some seventeen hundred copies, but in consequence of the death of the pub lisher the work is now out of print. The object of the althor is to revise the former work by omitting the treaties on inathematical instruments, to make room for kdditional matter that had been overlooked in the former work, in order to furnish house carpeters and builders with L new and easy system of lilies founded on geometrical principles for framing the most dimcult roofs for cutting every description of joints and for finding the sec. tions of angular pieces at any point from a horizontal to a erpendicular, so that their sides shall be in the plane the sides they are connected with for finding the form of the raking mould. for a gable, to intersect with the horizontal mould at any iingle diverging from a straight line the nitreing of circular mouldings the relative sizes of timbers framed to support s given weight to the rnitreing of planes oblique to the base at my angle. Together with these rules, the altthor also presents tables of the weight and cohesive strength of the differeut mterials uscd in the constructiorr of buildings as well as the weight required to crush said materils, vith a treatise on the adhesion of nails, screws, iron pins and glue. Also an easy system of siir railing for straight end platform stairs, which will enable carpeuters to finish and complete a dwelling without the assistance of a professional stair builder and to all this is added a practical and mathematicaldemonstration of finding the circumference and squaring the circle when the diameter is given. There can be but little doubt that a work of this kind is needed by architects and builders. and especially by carpenters and worlrmon who are inexperienced in the different kinds of labor which they are called upon to perform. Many a journeyman carpenter has found himself suddenly thrown out of employment simply because he was ignorant of the rules by which he could perform some required task. It is rather for the benefit of such than for the experienced workmen, that this volume is designed, and should it be the means of promoting their interest or inciting them to a study of the noble science and art of construction, the author will feel well compensnted for his Iabor. It is but due to cknowledge that me have consulted the valuable works of Thomas Tredgold, for the articles on the strength and weight of matials, also to Mr. Honetus M. Albee, a skillful and experienced stair-builder for the niethod of finding the distnces to kerf the back string for circular stairs.
