With the election of Woodrow Wilson in 1912, Louis D. Brandeis emerged as the undisputed intellectual leader of those reformers who were trying to recreate a democratic society free from the economic and political depradations of monopolistic enterprise. But now these reformers had a champion in the White House, and direct access to him through one of his most trusted advisers. In this volume we see what was probably the high point of progress...

Two groups of volunteers having no eye disease were examined electro-oculo­ graphically twice at ten minute intervals. One group smoked in the break, one didn't. In the non-smoking group there are a number of significant correlations between the tested parameters in the dark-period and in the light-period, which could not be found to the same degree in the smoking group. The fact that there were differences between the two groups-even though n...

The 1973 - postgraduate courses in ophthalmology held under the auspices of the Netherlands Ophthalmological Society, mark the 25th anniversary of the rebuilt Rotterdam Eye Clinic. The themes set for these courses: 'Ophthalmic Photography', 'Electro­ ophthalmology' and 'Echo-ophthalmology', have been chosen from a multitude of rapid developments in ophthalmology during this period. The aim was to provide the clinician with a lead in a bewilder...

The purpose of this symposium on light-coagulation is not to show the superi­ ority of the argon-laser-coagulation or, on the contrary, of the classical photo­ coagulation, but rather to see, if possible, which are the respective indications and contraindications for xenon-are-coagulation as well as for argon-laser­ coagulation. So, for instance, the argon-Iaser-coagulator is perhaps more appropriate to treat the lesions at and around the macu...

does not vary more than 1 % over the whole surface. Stimulus: The luminance of the stimuli can be regulated by means of neutral density filters. These filters are neither entirely neutral nor completely uniform, but these variations are not significant for perimetry. The maximum luminance of the stimuli is standardized at 1000 asb (316 2 cd.m-). The standard GP for kinetic perimetry has 3 neutral density filters which reduce the luminance by 0...

To mathematicians, mathematics is a happy game, to scientists a mere tool and to philosophers a Platonic mystery - or so the caricature runs. The caricature reflects the alleged 'cultural gap' between the disciplines­ a gap for which there too often has been, sadly, sound historical evidence. In many minds the lack of communication between philosophy and the exact disciplines is especially prominent. Yet in the past there was no separation - e...

This remarkable collection of material is as relevant today as when it was first published, graphically demonstrating the native African's struggle for peace, freedom, and equality in his native land during the 19th and 20th centuries.

Hausner's handbook covers the entire field of powder metallurgy with its various branches and refinements, while at the same time remaining within the bounds of manageable size and readability. It is a concise presentation concentrating on graphical presentations and tables to explain basic relationships between the principles and technology of powder metallurgy. This book is a valuable guide not only for students and teachers but also for t...

The Fourth International Congress for Logic, Methodology, and Philos­ ophy of Science was held in Bucharest, Romania, on August 29-September 4, 1971. The Congress was organized, under the auspices of the Inter­ national Union for History and Philosophy of Science, Division of Logic, Methodology and Philosophy of Science, by the Academy of the Socialist Republic of Romania, the Academy of Social and Political Sciences of the Socialist Republic ...

The International Astronautical Federation is the only professional society in the field of aerospace engineering and Sciences which brings together specialists of all countries interested in the exploration and peaceful exploitation of space. At its annual Congresses a large number of invited and/or carefully selected con­ tributed papers are presented which cover a wide variety of topics and are distributed over a number of sessions, each on...

A shortage of water exists, not only in the arid regions of the world, but even in some moderately humid climates. This situation is a consequence of water require­ ments for agriculture and industry in amounts greater than the natural surplus. Even in Europe there is increased anxiety over the state of water reserves, and shortages are forecast for the near future if industry continues to expand. During the past 50 years in the United States,...

This book provides the first monograph of Coccinellidae. Although the group finds inclusion both in Clausen's (1940) "Entomophagous Insects" and in Balduf's (1935) "Entomophagous Coleoptera", reference in these works is limited to three and twenty pages respectively. Moreover, the last thirty years since these books appeared have ~een a great deal of work on the group. The use of insecticides largely destroyed the early attempts at biological ...

Although biological exploration in Surinam started about 300 years ago, a thorough account of the Surinam herpetofauna has not hitherto been publish­ ed. Several publications on the subject have been issued (see below), but none of them was comprehensive. However, there are several papers dealing with a part of the Surinam lizards. The main reason for the absence of a complete review of the Surinam lizards (and, for that matter, of the entire ...

The original stimulus which started KENNETH SPENCER on a study of the Agro­ myzid flies was an invitation, which he accepted, to translate from the German the monograph on Leaf Miners by Professor E. M. HERING. From this developed nearly 20 years of collaboration until Professor HERING's death in 1967. Dr. SPENCER has himself described over 600 new species in the family, many of which he collected and reared from known host plants during his e...
