Abstract Blood samples obtained from 130 putrefied bodies were studied for endogenous ethanol (postmortem neoformation). An objective method of establishing the degree of putrefaction was developed and correlated with the determined ethanol concentration. The ethanol concentration of the vitreous humor was found to be…
The organic compound 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) has previously been observed to undergo a large increase in conductivity on irradiation with energetic particle beams. In this letter, we describe the electrical characteristics of novel rectifying junctions employing unirradiated PTCDA vapor de…

A model of the electrochemical conditions in a static crack has been developed for steel in the active state based on the steady‐state mass transport of species by diffusion and ion migration. The main reactions considered were anodic dissolution, hydrolysis of ferrous ions, and cathodic reduction of hydrogen ions and…
Abstract The mechanical properties of binary blends of high‐density polyethylene and polypropylene are quite good compared to those for blends of some other immiscible pairs. The property relationships observed depend strongly on the process used to fabricate the blends as shown by comparisons of specimens made by inj…
Abstract The cellulose/lithium chloride/dimethylacetamide (DMAc) and cellulose/lithium chloride/ N ‐methyl‐2‐pyrroilidinone (NMP) solutions were investigated by 13 C NMR spectroscopy. Well‐resolved spectra were obtained for both solutions and indicated that cellulose was present in these systems in the form of underiv…

Summary A simplified method to calculate CaCO3 saturation is developed using only commonly measured field parameters. The calculated saturation index, Is, and pH values are accurate at high temperatures and pressures in brines and are compared with less sophisticated and more complex calculations. The final forms of I…
During constant‐rate heating to 350°C in concentrated NaOH solutions, cubic ZrO 2 crystallized at ∼120°C from hydrated amorphous ZrO 2 ; these One cubic ZrO 2 particles abruptly changed into needlelike monoclinic ZrO 2 single crystals at 300°C. Crystallization and phase transformation were studied by XRD, TEM, and EPM…

The visible and near ultraviolet absorption spectra have been measured for thin films of H2Pc [C32H18N8], MgPc, FePc, CoPc, CuPc, and ZnPc. Magnesium and iron phthalocyanine have very different absorption spectra. For most of the phthalocyanines, structure of magnitude 0.21 eV is seen on the visible and Soret bands. A…
Seven types of corrosion and precorrosion of painted metals are reviewed: blistering, early rusting, flash rusting, anodic undermining, filiform corrosion, cathodic delamination, and wet adhesion. The importance of the nature of the interfacial region between the coating and the metal is emphasized. Ten unsolved probl…
Si, Si 3 N 4 , and SiC powders which possess a unique set of characteristics were produced by a laser‐driven gas‐phase synthesis process. The powders have a fine particle size (<0.1 μm), are spherical, have a narrow range of particle sizes, are free of hard agglomerates, have a high degree of phase purity, and have…

Careful measurements of infrared spectra of synthetic diamonds bring to light two apparently contradictory observations. On the one hand, it is shown that there is an excellent correlation between the strengths of the nitrogen-induced absorption at 1130 cm−1 and of the local-mode absorption peak at 1344 cm−1. On the o…
1 The relative potency of effect of a wide range of halogenated and unsubstituted hydrocarbons on the central nervous system (CNS) and the heart of experimental animals have been determined. 2 The chemicals used caused either stimulation or depression of the rat CNS after 10 minutes' inhalation of concentrations rangi…
The Rayleigh number R, in a horizontal layer with temperature-dependent viscosity can be based on the viscosity at T 0 , the mean of the boundary temperatures. The critical Rayleigh number Roc for fluids with exponential and super-exponential viscosity variation is nearly constant at low values of the ratio of the vis…
