Fifteen years ago, Hall described clearly the advantages of the thin section approach to biological x-ray microanalysis, and described clearly the ratio method for quantitive analysis in such preparations. In this now classic paper, he also made it clear that the ideal method of sample preparation would involve only freezing and sectioning at low temperature. Subsequently, Hall and his coworkers, as well as others, have applied themselves to the task of direct x-ray microanalysis of frozen sections. To achieve this goal, different methodological approachs have been developed as different groups sought solutions to a common group of technical problems. This report describes some of these problems and indicates the specific approaches and procedures developed by our group in order to overcome them. We acknowledge that the techniques evolved by our group are quite different from earlier approaches to cryomicrotomy and sample handling, hence the title of our paper. However, such departures from tradition have been based upon our attempt to apply basic physical principles to the processes involved. We feel we have demonstrated that such a break with tradition has valuable consequences.

This book brings together in compact form a broad scientific and sociopolitical view of US wetlands. This primer lays out the science and policy considerations to help in navigating this branch of science that is so central to conservation policy, ecosystem science and wetland regulation. It gives explanations of the attributes, functions and values of our wetlands and shows how and why public attitudes toward wetlands have changed, and the political, legal, and social conflicts that have developed from legislation intended to stem the rapid losses of wetlands. The book describes the role of wetland science in facilitating the evolution of a rational and defensible system for regulating wetlands and will shed light on many of the problems and possibilities facing those who quest to protect and conserve our wetlands.

The most complete section of the glacial series of deposits described and illustrated in Lamplugh's classic paper entitled “On the drifts of Flamborough Head” is that which is located at Danes' Dyke.Referring to this section Lamplugh says:—“I have spent much time in exploring this section, and consider that the beds up to this horizon represent the Basement Clay, while the persistent upper band of brown Boulder-clay (3) is all that remains of the upper Clay of Sewerby, this bed and the underlying sand and gravel (3b) together taking the place of the Purple Clays of Bridlington and Holderness. Above this clay lie the Sewerby Gravels (2b), the lower part chalkless and the upper layers composed chiefly of chalk-pebbles, as noticed farther west. A few feet of loamy stuff overlies these gravels at the cliff top (2c), resembling a weathered Boulder-clay, and a little farther east (near Hartindale Gutter) a seam of Boulder-clay certainly appears in these gravels, their contemporaneity with the uppermost part of the Boulder-clay, and consequently their Glacial age, being thus fully established.”

Chronic nonspecific diarrhea of infancy (CNSD) or irritable bowel syndrome represents one of the most common gastrointestinal problems confronted by practicing pediatricias. In the subspecialty setting of the pediatric gastroenterologist, this entity comprised almost 35% of the outpatient referral practice. CNSD, originally thought to be part of the celiac syndrome, was described as a separate clinical entity by Cohlan in 1956.1 Since that time in the classic paper on this subject, Davidson and Wasserman2 have described consistent diagnostic criteria further characterizing CNSD as a recognizable syndrome. The onset of symptoms occurs classically between 6 and 30 months of age with the development of three to six loose stools with mucous per day, with no associated malabsorption or growth and development abnormalities (to be discussed in detail below). Whereas spontaneous resolution of CNSD is anticipated by 39 months of age, longitudinal observations indicate that these patients have a high incidence of functional bowel complaints during adolescence and beyond suggesting a continuum with "irritable bowel syndrome" of adulthood.3 From the standpoint of the child, this "complaint" all too frequently becomes the "problem" when the frequency and/or consistency of the bowel movements impair training or become intolerable to the parents.

Erik Moberg pioneered the idea of validating measures of sensory function following peripheral nerve suture by correlating their results with those of functional tests. However it is important that powerful prior variables (age at suture, time elapsed since suture and delay between injury and suture) be controlled. Failure to do this may result in spurious correlations, as illustrated by analysis of two sets of data, one collected by the author and the other given in the classic paper of Önne (1962).
