Gaeumannomyces graminis var. graminis is an ectotrophic, root-infecting fungus found on some warm-season turfgrass species (1). A sample of seashore paspalum (Paspalum vaginatum) exhibiting rotted roots and stolons was taken from dying patches of tur

This paper describes a very simple low level coincidence circuit of moderate speed, which is suitable for use with two or more multiplier photo‐tubes in a scintillation detector of radiation. The operation of the circuit is analyzed, and performanc

The construction and properties of a novel spark light source are described. The intense, brief light pulses make possible a simple velocity-of-light demonstration experiment of 1% accuracy, using an oscilloscope for measuring the separation in time

The Scylla plasma experiment, which employs a rapidly rising magnetic field in a cylindrical mirror geometry to produce and heat a deuterium plasma, is described. Experimental studies of the reproducible neutron emission from the hot plasma show that

A number of powder patterns found on demagnetized strain-free crystals of silicon-iron of known orientation are illustrated and discussed. The specimens were cut from strips of transformer steel in which fairly large crystals had been grown by the st

An arbitrary two‐dimensional magnetic field may be uniquely specified by listing all coefficients of the power‐series expansion of its complex potential function. An experimental procedure is described in which the first N coefficients are derive

The magnetization curves of colloidal magnetite (${\mathrm{Fe}}_{3}$${\mathrm{O}}_{4}$) and colloidal siderac ($\ensuremath{\gamma}$-${\mathrm{Fe}}_{2}$${\mathrm{O}}_{3}$) have been determined by a null method for fields from 0 to 400 gauss. The meas

When the transient response of a linear network to an applied unit step function consists of a monotonic rise to a final constant value, it is found possible to define delay time and rise time in such a way that these quantities can be computed very
