A synopsis of the weather problems facing today's general aviation pilots
Concentration on weather to data has primarily been at the point of observation. There have been efforts to obtain and disseminate en route weather through pilot reports (PIREPS), but the efforts have been meager. What is needed is the cooperative efforts on the application of technology to the acquisition and dissemination of the en route weather data for those pilots in the air as well as those who are flight planning on the ground. A comprehensive three-dimensional computer storage system is proposed that receives weather information from all aircraft on IFR flight plans and stores this information by altitude and geographic coordinates. Also, a report on the Federal Aviation Administration's Research Engineering and Development Aviation Weather Program from the aspect of past, present and future is given
An Investigation of Whistlers and Chorus at High Latitudes
The whistlers and chorus received at College, Alaska during the period
from December 1955 through March 1958 are studied particularly with respect
to temporal variations.
The diurnal curves for whistler activity show maxima after midnight
local time while the seasonal variation peaks during the winter. It appears
that these variations in whistler activity are in part explainable in
terms of very low frequency propagation conditions.
The diurnal variation of chorus shows a maximum at about 1400 hours
local time. By the use of data from lower latitude stations a dependence
of this time of diurnal maximum on the geomagnetic latitude of the station
is shown.
The coefficients of correlation for chorus activity versus magnetic
activity were determined on a monthly basis. A seasonal variation in these
correlations is indicated which appears to be unique for the geomagnetic
latitude of College.
A preliminary statistical study of one of the more easily measured
characteristics of chorus is discussed. The characteristic chosen is the
mid-frequency in an element of chorus. A diurnal variation in this parameter
is indicated.The research reported in this document has been sponsored by

Automatic patient respiration failure detection system with wireless transmission
Automatic respiration failure detection system detects respiration failure in patients with a surgically implanted tracheostomy tube, and actuates an audible and/or visual alarm. The system incorporates a miniature radio transmitter so that the patient is unencumbered by wires yet can be monitored from a remote location
Swarm Theology
After showing the unsuitability of continuing to use some earlier models of divine action,
the author examines the implications for God\'s involvement in the world suggested by the current
understanding of the behavior of complex systems

Miniature ingestible telemeter devices to measure deep-body temperature
A telemetry device comprised of a pill-size ingestible transmitter developed to obtain deep body temperature measurements of a human is described. The device has particular utility in the medical field where deep body temperatures provide an indication of general health
Professionalism, prejudice and personal taste: does it matter what we wear?
An earlier opinion piece considered the professional issues surrounding the occupational therapist’s dress code within the work place (Davys et al, 2006). This second paper considers the role of the occupational therapist when a client choice of clothing may conflict with social expectations and negatively impact upon social inclusion. Three practice based scenarios are presented, which serve as the prompts for reflection upon informed choice, professional responsibilities and the therapeutic relationship. This paper concludes that there needs to be debate about the conflict between each of these areas and the concept of social inclusion
Protective encapsulation of implantable biotelemetry units
Development of materials for encapsulating electronic devices used in biotelemetry is discussed. Chemical resistance of materials to effects of animal fluids is described. Silicone rubber is recommended as basic material with polymers applied to outer surface for protective coating
