From the time when fluoroscopic screens were first used there have been scattered references to reduction in their light output due to age, use, etc. References are scarce and usually devoid of quantitative data. A long-range program has been set...

The object of this study is the synthesis of trans-cyclopentane-1, 2-dicarboxylic acid. Five procedures designed for the synthesis of this trans diacid are described in the literature. The procedure devised by Perkin in 1887, Fuson and Cole in...

A short history is given of cathode-ray tubes, from the earliest laboratory tubes available during the early 1900's through present day high performance tubes. Special attention is paid to the development of post-deflection acceleration types...

An instrument which measures current from D.C. to 50 megahertz by clipping a transformer core around a current carrying conductor is discussed. A Hall device, which is installed in the core cross-section, detects the flux in the core. This Hall...

Avian myeloblastosis virus RNA was fractionated into a high molecular weight RNA and a low molecular weight RNA fraction by sucrose density centrifugation. The larger RNA component had a sedimentation constant of 65S and the low molecular weight...

The association of other materials with DNA has been studied extensively in higher organisms and more recently in bacteria. However, investigation of these complexes in bacteria have for the most part been restricted to the study of a specific...

Copper in blood and liver can be divided into several fractions. Copper in blood is about evenly divided between erythrocytes and plasma. Normal concentrations for most species range between one and two parts per million. Plasma copper is mainly a...

Studies of some components of test weight in Soft White wheat revealed distinct subclass differences. Wheat kernels of Soft White more completely occupied a given volume than did kernels of White Club. The Soft White kernels were larger and had a...

The presented study was undertaken to determine the operational catabolic carbohydrate pathway(s) contributing to the synthesis of the DNA of the actinophage for Streptomyces griseus. The incorporation of glucose-6-¹⁴C versus glucose-1-¹⁴C was...

Ruelene was orally administered to three female sheep at a dosage rate of 121.5 mg /kg. The cholinesterase (ChE) activity levels of blood plasma, red blood cells (RBC), and mosquitoes (Aedes aegypti) which had fed on the sheep were tested at...

The role of nematodes (Diplogaster lheritieri Maupas 1919) as excretors of pathogenic organisms was studied. Salmonella typhi and Salmonella wichita were fed to nematodes for two days. The nematodes were surface sterilized with free chlorine. The...

A study to determine the oxygen transfer rates in selected waste liquids and to compare these rates with that of distilled water was performed. Tests using treated sewage and pulp and paper mill effluent were conducted in a model aeration tank....

The effects of x-irradiation on quantitative genetic traits was investigated by comparing the response of irradiated mice to selection for litter size and 28-day weight with the response to selection for the same two traits in non-irradiated...

High nitrogen (N) accumulation in terrestrial ecosystems can shift patterns of nutrient limitation and deficiency beyond N toward other nutrients, most notably phosphorus (P) and base cations (calcium [Ca], magnesium [Mg], and potassium [K]). We...

The quantity and characteristics of coarse woody debris (CWD) were examined in four distinct pine ecosystems of north-western (NW) Spain, NW Russia and the NW USA. The average CWD volume and biomass ranged from 3.76 m³ ha⁻¹, 1.55 Mg ha⁻¹ in pine...

With the growing popularity of kinesiology at the undergraduate level, one would expect the field to be influential. Kinesiology, however, appears to be in a paradox. The undergraduate popularity is not reflected in the rest of academia, or even...

The presence of the etiologic agent of "salmon poisoning" disease, Neorickettsia helminthoeca, was demonstrated in eggs of the trematode vector, Nanophyetus salmincola. Three dogs were given 100,000 and one dog 82,000 ground fluke eggs by...
