The motion of the periodic Toda lattice is explicitly determined in terms of Abelian integrals.

When the absorbance at 240 nm. of a solution of sodium iodide was measured by 159 laboratories using narrow-band-pass spectrophotometers, 15% reported results that suggested a problem caused by stray light. The laboratories were also requested to measure the absorbance at 240 nm. of solutions of acid potassium dichromate and ...

There are many serious problems that beset society in general and medicine in particular. Some are related to the social and economic revolution that currently involves the world and will necessarily affect the practice of surgery. There is considerable evidence to indicate that one of the main battlefronts in this ...

The surgical commitment of No. 2 Field Hospital, R.A.M.C., during its stay in Jordan is presented. The majority of patients that were admitted had sustained war wounds, many of which were infected due to the delay in treatment. The difficulties encountered in their subsequent management are discussed. Special reference is ...

A study has been made of Cauchy's problem for a class of abstract parabolic differential equations. Our study is based upon a transformation that maps solutions of second-order abstract Cauchy problems into solutions of first-order. This is a preliminary report on some of the results obtained. These results include (1) ...

In this note a singular abstract Cauchy problem is considered. A solution is obtained for this problem in terms of a regular abstract Cauchy problem. As an application we obtain a new solution of the initial value problem for a class of singular partial differential equations.

Nearly every physician will be required at one time or another to provide a cardiology opinion on a patient about to undergo or who has recently undergone surgical intervention. The variety of cardiac problems one is faced with are obviously immense, but the purpose of this article is to highlight ...

The population problem has no technical solution; it requires a fundamental extension in morality.

Although beta-propiolactone (BPL) is an effective vapor-phase decontaminant for enclosed areas, some problems have been encountered in its use. Adequate air circulation during BPL dissemination could eliminate most of these problems. It is recommended that, when decontaminating the ordinary building or laboratory, the amount of BPL sprayed be changed from ...

The central question to be discussed in this paper is whether the structure established for sperm whale myoglobin in the crystalline state is the same as that of the protein in solution. As judged by its ultraviolet optical rotatory dispersion, the helical content of metmyoglobin in solution does not differ ...

Thin sections of embryonic avian bone decalcify during preparation for electron microscopy, creating a false impression of mineral distribution. The results of the experiments reported herein show that viscous embedding materials do not penetrate compact formed bone, and so, in thin sections, the calcium apatite crystals may be leeched out ...
