The Caddis Flies, or Trichoptera, of Illinois (1944). Herbert H. Ross, illustrated by C. 0. Mohr, K. M. Sommerman, and the author. Entomological Reprint Specialists, Los Angeles, California, 1972. 8 unnumbered pages plus pp. 1-326, figures 1-961 plus frontispiece. Bound, $9.95.

After its initial appearance in August, 1944, as Bulletin of the Illinois Natural History Survey, Vol. 23, Art. I, this work quickly became a classic. With the passage of time it has continued to gain in stature. The great expansion of interest in the Trichoptera, to which Dr. Ross calls attention in his preface to the reprint edition, has been stimulated to a significant degree, by The Caddis Flies of Illinois

Noncontact torque measurement using stroboscopic techniques

Noncontact torquemeter measures torsional deflection of rotating shaft and results are viewed on vernier scale. Magnitude of torque must be calculated from measured deflection. Device has no electric connections with the rotating member and is easy to use

Microwave technique measures plasma characteristics

Plasma electron density and temperature distribution are measured by passing a high frequency millimeter wave through plasma. Variations in density and temperature are determined by measuring insertion loss as the plasma travels between the microwave transmitting and receiving antennas

Alignment apparatus using a laser having a gravitationally sensitive cavity reflector

A description is given of a device for determining a true gravitational vertical. The apparatus is composed of a vertically disposed laser with a gravitationally sensitive lower regeneration reflector. The reflector enables an output beam to be developed only when the optical axis of the laser is disposed normal to the gravitationally sensitive reflective surface. In an alternative embodiment, the devices is combined with a servo system to provide a gravitationally stabilized horizontal platform

A Proposal to Finance Long-Term Care Services through Medicare with an Income Tax Surcharge

Proposes expanding Medicare to cover comprehensive long-term care services, including home care and custodial nursing home care, and financing this expansion of benefits with a surcharge on federal income taxes

The Lewis Heat Pipe Code with Application to SP-100 GES Heat Pipes

The NASA Lewis Research Center has a thermal management program supporting SP-100 goals, which includes heat pipe radiator development. As a part of the program Lewis has elected to prepare an in-house heat pipe code tailored to the needs of its SP-100 staff to supplement codes from other sources. The latter, designed to meet the needs of the originating organizations, were deemed not entirely appropriate for use at Lewis. However, a review of their features proved most beneficial in the design of the Lewis code
