Abstract: There are systems and methods for performing a geophysical survey using a hybrid aircraft which includes an apparatus configured to perform the geophysical survey. The system including: three mutually orthogonal transmitters configured to transmit electromagnetic (EM) waveforms towards the ground which creates a secondary magnetic field, wherein the three mutually orthogonal transmitters are attached to the hybrid aircraft; three mutually orthogonal null-coupled receivers configured to obtain measurements associated with the secondary magnetic field, wherein the three mutually orthogonal null-coupled receivers are attached to the hybrid aircraft; and three mutually orthogonal gradient receivers configured to obtain measurements, wherein the three mutually orthogonal gradient receivers are attached to the hybrid aircraft.

Abstract: A method, system and software are provided for automatically generating data entry forms customized for a particular school to satisfy university, conference and national compliance policies for student athletes. The form are provided electronically and the information entered into the forms by each student athlete is stored in a database. An administrator, coach, or other school official may then access appropriate data forms for each student athlete so that compliance with various scholastic or organizational requirements can be monitored and managed.

Abstract: Disclosed is a method and composition useful for etching steel prior to metal plating which can be followed by enamelling. The etching composition contains sodium benzene sulphinate and an acid and promotes adhesion of metal and enamel coatings applied over the etched surface.
