A Southwest Electrostatic Sprayers, Inc., nozzle was configured to a Hudson PortaPak backpack. A test was run to compare deposition of BVA no. 13 oil by the electrostatic nozzle to a standard nonelectrostatic nozzle as collected by Teflon slides. Results indicate that 100% greater deposition occurred with the electrostatic nozzle.

Purpose/Objectives: Indolent lymphomas are exquisitely sensitive to radiation therapy (RT). Programs of 2Gy × 2 were shown be highly effective in controlling irradiated site(s). During the COVID-19 pandemic, International Lymphoma Radiation Oncology Group (ILROG) proposed guidelines that offered substitution Boom (2Gy 2) regimen with Big 4Gy 1. This report compares our center’s experience both ...

Eight male subjects in each of three age groups (21-26, 40-45, 60-72 years) slept in pairs in the CAMI sonic boom simulation facility for 21 consecutive nights. The first five nights were used to acclimate the subjects (nights 1 and 2) and to obtain Baseline data (nights 3-5); the 12 subsequent nights (Boom) involved the hourly presentation of simulated sonic booms at an overpressure level of 1...

The practical use of high-fidelity multidisciplinary optimization techniques in low-boom supersonic business-jet designs has been limited because of the high computational cost associated with computational fluid dynamics-based evaluations of both the performance and the loudness of the ground boom of the aircraft. This is particularly true of designs that involve the sonic boom loudness as eit...

SUMMARY The sonic boom simulator of the Langley Research Center was used to quantify subjective loudness and annoyance response to simulated indoor and outdoor sonic boom signatures. The indoor signatures were derived from the outdoor signatures by application of house filters that approximated the noise reduction characteristics of a residential structure. Two indoor listening situations were ...

Political and industrial factors-beyond the economic headwinds-may be causing public investment in biomedical research to slow down around the world.

lore, be an impressive one, and will, as is usual on such occasions, be distinguished by an outpouring of eloquence, and it is to be hoped a loosening of purse strings. Dr. Patrick Manson has worked the scheme with energy and success. A great number of tropical practitioners have testified in the medical journals regarding the benefit they have gained from attending the practice of the Albert D...
