Slender rings and their products are characterized in terms of algebraic and topological properties. Possible limitations on uncountable products of such rings are discussed. Ring, module, and topological terminology and notation are standard. R denotes a unital ring with identity 1, and R ω denotes its countable product, that is, the set of all sequences of elements of R. Of course ω {0, 1,. ....

Slender concrete walls incorporated into tilt-up construction over the past 60 years have performed remarkably well under out-of-plane wind and seismic loads. While issues associated with seismic wall anchorage gave this form of construction a black-eye in the early days, the concrete walls themselves have always performed very well even as far back as their first use in the early 1900s. Yet th...

A fast discrete model for the simulations of thin charged jets produced during the electrospinning process is derived, based on an efficient implementation of the boundary element method for the computation of electrostatic interactions of the jet with itself and with the electrodes. Short-range electrostatic forces are evaluated with slender-body analytical approximations, whereas a hierarchic...

Bilateral microtia, absent patellae, short stature, poor weight gain, and characteristic facial features are described in two female sibs. Other skeletal anomalies included complete habitual dislocation of the elbow, slender ribs and long bones, abnormal modelling of the glenoid fossae with hooked clavicles, and clinodactyly. Bone age was significantly delayed and there was flattening of the ep...

Panagrellus ceylonensis n. sp. is described from rubber latex in Ceylon. Its long, slender spicules are curved ventrally with a dorsal deflection at two-thirds of their length. The manubrium is thick and hooked, and the shaft is not widened at the shoulder. The terminal bifurcations are wide, with the dorsal one considerably longer and thicker than the ventral. The main ventral element is conti...

A long, slender filarial nematode was removed from the left anterior chamber of a resident of Oregon after several days of pain and blurred vision. The worm was identified as an Onchocerca, but it could not be further identified. This worm is the third zoonotic Onchocerca removed from the anterior chamber and the second case reported from the United States. Cases of zoonotic onchocerciasis cont...

The orientational order and dynamics in suspensions of self-locomoting slender rods are investigated numerically. In agreement with previous theoretical predictions, nematic suspensions of swimming particles are found to be unstable at long wavelengths as a result of hydrodynamic fluctuations. Nevertheless, a local nematic ordering is shown to persist over short length scales and to have a sign...

In a radio-wave shield, a method of blocking radio waves in which a space is surrounded by a high loss dielectric material, some waves leak through the long and slender gap between the walls. We analyzed the losses in the gap section and in the gap aperture. The former was analyzed by using an equivalent parallel board transmission line, the latter by using an aperture field method. Here we des...

A characteristic type of reticular cell, the dense reticular cell is described and illustrated by electron microscopy in the thy mus and lymph nodes of mice. This cell is identified by its high nuclear and cytoplasmic density and by the presence of many ribosomes in its long, slender processes extending between lym phocytes (or thymocytes). The preservation of these processes requires special f...

Betadevario, new genus, with the single species B. ramachandrani, new species, from Karnataka, southwestern India, is closely related to Devario but differs from it in having two pairs of long barbels (vs. two pairs of short or rudimentary barbels, or barbels absent), wider cleithral spot which extends to cover three scales horizontally (vs. covering only one scale in width), long and low lamin...
