On April 25-27, 1989, over a hundred mathematicians, including eleven from abroad, gathered at the University of Illinois Conference Center at Allerton Park for a major conference on analytic number theory. The occa­ sion marked the seventieth birthday and impending (official) retirement of Paul T. Bateman, a prominent number theorist and member of the mathe­ matics faculty at the University of Illinois for almost forty years. For fifteen of t...

The use of computer-based image analysis systems for all kinds of images, but especially for microscope images, has become increasingly widespread in recent years, as computer power has increased and costs have dropped. Software to perform each of the various tasks described in this book exists now, and without doubt additional algorithms to accomplish these same things more efficiently, and to perform new kinds of image processing, feature di...

This volume is dedicated to the Third International Symposium on Microneurosurgical Anastomoses for Cerebral Ischemia, which took place in Rottach-Egern, June 2&-30, 1976, under the sponsorship of Professor F. Marguth, Director of the Depart­ ment of Neurosurgery, Ludwig-Maximilians-University of Munich (West Germany). It contains the continuing devel­ opments of the extra- intracranial arterial bypass (EIAB) for cerebrovascular occlusive dise...

The esophagus, ostensibly a simple tubular structure whose functional role often is minimized and even ignored, is, in re­ ality, a highly complex viscus. The problems associated with disorders of the esophagus are not only related to the usual en­ tities which may be anticipated in any portion of the gastroin­ testinal tract, but include in a major fashion the functional mechanisms indigenous to the pharyngoesophageal and eso­ phagogastric ju...

by Dr. Nathaniel R. Bronson, 11 This volume serves a two-fold purpose very nieely. For the ophthalmologist there is a presentation of the teehniques and results of ultrasonie examination of the eye and orbit. For the radiologist or general ultrasonographer the essential oeular anat­ omy and pathology are deseribed with these findings. Unlike eon­ ventional x-rays or statie general body ultrasonograms, the exami­ nation of the eye by real-time ...

This volume, focusing on the ureter and the diseases which involve it, is an updated second edition. Many journals and textbooks deal with the physiology, pathology, diagnosis, and therapy of derangements of the urinary tract. In most instances, however, the discussion properly centers on the disease process itself and its primary aspects, with only a tan­ gential description of effects on the ureter. The editor is therefore correct that the u...

It has been more than twenty years since the isolation of polyoma virus and SV40, and the reports that they could produce tumors in animals and transformation of cells in culture. What was startling was that these biologic properties are associated with viruses that contain genetic in­ formation that is able to code for only five or six proteins. Since that time, investigations with these viruses have been in four principal areas. One major ar...

After the Second World War the number of biliary diseases has abruptly risen and lithiasis has become in many regions the most frequent surgical disease of the abdomen. At present, though there are perspectives of rational conservative treat­ ment and though endoscopic techniques permit removing some of its complications even without laparotomy, the basic treatment method still remains, and probably shall remain for long the classical surgical...

The 35th Annual Denver Conference on Applications of X-Ray Analysis was held August 4-8, 1986, on the campus of the University of Denver. Since the previous year's conference had emphasized x-ray diffraction, this year the Plenary Session spotlighted x-ray fluorescence, with the title "Trends in XRF: A World Perspective, " featuring renowned speakers from three major areas. XRF IN NORTH AMERICA, by Prof. D. E. Leydon, from Colorado State Unive...

A conference on Analytic Number Theory and Diophantine Problems was held from June 24 to July 3, 1984 at the Oklahoma State University in Stillwater. The conference was funded by the National Science Foundation, the College of Arts and Sciences and the Department of Mathematics at Oklahoma State University. The papers in this volume represent only a portion of the many talks given at the conference. The principal speakers were Professors E. Bo...

It has become an annual custom for the Physiological Society of Philadel­ phia to sponsor a spring symposium in honor of A. N. Richards (\876-1966), a research pharmacologist who developed the classical micropuncture tech­ nique for studying kidney function. The A. N. Richards Symposium for 1979 was held on April 23-24 in Valley Forge, Pennsylvania. The theme of this symposium was "The Actions of Taurine on Excitable Tissues." Although taurine...

Renal function fails abruptly in a bewildering variety of clinical situations which lack any common clinical patterno This makes it impossible to define acute renal failure in the same way as heart failure or liver failureo Even oliguria, the commonest sign, is not invariably present. As a result, the detection of acute renal failure Table 1. Causes of acute renal failureo Acute tubular necrosis Ischaemic type Nephrotoxic type Cortical necrosi...

Das Problem der Intersubjektivitiit Intersubjektivität ist Husserl schon seit der Darstellung der Ideen I in Zusammenhang mit dem Problem der phiinomenologischen phänomenologischen Reduk­ tion sehr stark bewusst und wird, wie die neue VerOffentlichung Veröffentlichung 'Zur Phänome­ Phiinome­ nologie der Intersubjektivität'l Intersubjektivitiit'l ausdrücklich ausdrucklich zeigt, zeit seines Lebens in seinem Denken mit mehr oder weniger Intensit...

R. MARKS Biology has become a 'numbers game'. The advantages of being able to grade changes in tissue, submit results to statistical analysis and accurately record biological phenomena make measurement essential. This is as true for the various disciplines in applied biology as it is for the more esoteric aspects ofthe subject. Regrettably, sk in biologists until recently had not seized the opportunities that the availability of their tissue o...

The Workshop on the Seismicity and Seismic Risk in the Off­ shore North Sea Area was intended to bring together experts from a variety of disciplines as well as interest groups with involve­ ment in siting, design and construction of offshore structures in the region. Participants came from the fields of geology, seismology, oceanography, geotechnical and structural engineering and risk analysis. The wide range of participant affiliations incl...

PREFACE This volume is a sequel to yet independent of our Paranoia: A Study in Diagnosis, Reidel, Dordrecht and Boston, 1976. Whereas our first book centered on diagnosis, this centers on treatment. In our first volume, all discussions of nosology (theory of illness) and of treatment was ancillary to our discussion of diagnosis, similarly all discussion of this volume dealing with nosology - there is very little on diagnosis here - is ancillar...

VIrtually all the papers in these volumes originated in presentations at the Fourth Groningen Round Table, held in July 1980. That conference, organ­ ized by the Institute for General linguistics of Groningen University was the fourth in an irregular series of meetings devoted to issues of topical interest to linguists. Its predecessor, the Third Round Table, was held in June 1976, and dealt with the semantics of natural language. A selection ...

As requirements for high quality wastewater effluent increase, quantities of sludge generated also increase. Contaminants removed from wastewater concentrate in the sludge and can represent serious environmental insult and health effects if not properly managed. The cost of sludge handling can be estimated to constitute as much as 50% of the cost of wastewater treatment. If properly managed, however, sludge may be considered a resource of valu...

This volume is based on papers presented by invited speakers at a symposium entitled "Plant Nitrogen Metabolism" held in conjunction with the 28th Annual Meeting of the Phytochemical Society of North America. The meeting took place on the campus of the University of Iowa at Iowa City during June 26-30, 1988, and attracted 110 participants from 11 countries. The goal of the symposium was to trace the pathway by which nitrogen passes from soil a...
