Abstract Feldspars in Louisiana Miocene sandstones, at depths of 2,400 to 6,000 m (80 to 150 degrees C), show progresssive reaction with increasing burial. Plagioclase undergoes both dissolution and replacement by albite, whereas K-feldspar undergoes only dissolution. Reactions do not reach completion by 6,000 m (150…
The silica-scaled algae (Synuraceae, Chrysophyceae sensu lato) are compared to other Chrysophyceae, Phaeophyceae and Bacillariophyceae with occasional comparisons to other chlorophyll c-containing algae, scaled protozoa and oomycete fungi. The silica-scaled algae have several unique characters which separate them from…

Abstract Polypyrrole has been electrodeposited at a constant current density of 4 mA cm −2 onto Pt from 0.1 M pyrrole, 0.1 M NBu 4 BF 4 in dry CH 3 CN. The thickness of the polypyrrole has been varied over a wide range of 0.02 to 50 μm. Elemental analysis reveals an excess of hydrogen in the polymer. The electrochemic…
Abstract In this survey, we have concluded that carbon black reinforces ultimate properties of rubber by tear deviation. This can occur at the colloidal level, as the tear is forced to pass around carbon black aggregates, thus increasing the area of the torn surface. Colloidal tear deviation may be the cause of the in…

Pyruvate formate-lyase (PFL) (formate acetyltransferase; EC 2.3.1.54) of oral streptococci is essential for metabolizing sugar into volatile compounds (formate, acetate, and ethanol). This enzyme is extremely sensitive to oxygen, and its activity is irreversibly inactivated by oxygen. When Streptococcus sanguis was an…
A historical review is given on the proton tunneling model in KH2PO4 type ferroelectrics with reference to the experimental results which have been believed to be evidences of the model. Some of the theoretical results based on the model are shown to be inconsistent with recent dynamical experimental results suggestin…

Abstract Information on the interfacial region in incompatible polymer mixtures can be gathered using various techniques including electron microscopy, thermal transition analysis, and more sophisticated methods such as nonradiative energy transfer (NRET). Selected examples are reported here to illustrate the exciting…
The purpose of a perforator is to create in the casing a hole that extends into the formation to allow the efficient production or injection of fluids. This entrance hole may be made by any of three methods. Shaped-Charge Perforating The most common method of perforating is shaped-charge or "jet" perforating. The shap…

A bare metallic grating illuminated by a plane, S-polarized electromagnetic wave can completely absorb one of the diffracted orders. These strong absorptions have been reported to be accompanied by two different types of behavior. Here we calculate, by means of an exact differential method, the phase versus angle-of-i…

The effect of variable SO4− −concentrations (10−2 to 10−1 M) in slightly alkaline solutions (pH 8.2) on aluminum corrosion has been studied at different hydrostatic pressures (1, 100, and 300 atm). The solution temperature was 20 C, and it contained ~8 ppm of dissolved oxygen. It was observed that SO4− − ions have an…
