The paper presents a method for the determination of the critical minimum scantlings for small high-speed vessels. Particular attention is given to the shell plating strength for hydrodynamic impact loads. The suggested method uses an integrated approach involving assumed loads, suggested safety factors, and preferred stress-analysis method. The stress analysis uses plastic theory based partly on the works of J. Clarkson and Thein Wah. Included in the paper is a comparison of the relative structural strength of several commercial, military, and experimental hydrofoil vessels along with a few planing boats and a seaplane hull. This shows the variation of existing vessel structures and compares them to the results obtained by the suggested method. Most commercial, military, and recreational vessels exceed the minimum scantlings of the suggested method. The most significant deviation is the hull of the seaplane:

This report describes a method and instrumentation for determining myoglobin (Mb) oxygen saturation in skeletal muscle. Canine gracilis is frozen in situ using a liquid N2-cooled copper block. Transverse section surfaces of frozen unstained muscle are observed at -110 degrees C using a microspectrophotometric system. The Mb saturation is determined using epi-illumination and a four-wavelength optical method. A special aperture permits illumination of a 20-microns-square area, and the radius of the catchment volume is estimated to be approximately 60 microns, with the strongest signal arising from the central region. The equibestic wavelengths used were 546.6, 570.5, and 584.1 nm. The method was validated using the nonlinear multicomponent analysis method of Lubbers. End-point (0 and 100% saturation) calibration was set using ischemic and adenosine-treated highly oxygenated muscles, respectively. The effects of hemoglobin (Hb) and metmyoglobin (metMb) signal contamination were evaluated experimentally and by computer-mixing simulations. Mb saturation determinations adjacent to large vessels are to be avoided. MetMb and capillary Hb do not interfere with the determination. The reproducibility of the method is estimated to be +/- 5%.

Nondestructive Determination

The objective of this paper is to develop the technique of the embedded grid for three-dimensional strain and stress analysis. The application to the case of a sphere subjected to diametral loading is described and results are compared with theoretical and photoelastic ones. The limitations of the method are outlined and suggestions for improvement made. As it stands now, the method allows the nondestructive determination of three-dimensional strain fields with good precision. The determination of stresses, however, is less precise.

A new diamond-anvil cell apparatus for in situ synchrotron X-ray diffraction measurements of liquids and glasses, at pressures from ambient to 5 GPa and temperatures from ambient to 1300 K, is reported. This portable setup enables in situ monitoring of the melting of complex compounds and the determination of the structure and properties of melts under moderately high pressure and high temperature conditions relevant to industrial processes and magmatic processes in the Earth's crust and shallow mantle. The device was constructed according to a modified Bassett-type hydrothermal diamond-anvil cell design with a large angular opening (θ = 95°). This paper reports the successful application of this device to record in situ synchrotron X-ray diffraction of liquid Ga and synthetic PbSiO3 glass to 1100 K and 3 GPa.
