Abstract: The present invention relates to the identification of adult human stem cells as well as the identification of metastatic cancer cells by detecting the expression of Oct-4, and the lack of GJIC activity. The invention further provides methods of identifying compounds that possess carcinogenic initiator activity, as well as compounds that protect against this earliest stage of cancer.

Abstract: A centrifugal force-activated signal light assembly for use in a vehicle is disclosed in which a metal weight is suspended from a metal conical spring at the bottom side of a set of battery cells inside a metal casing and vibrated to touch the metal casing intermittently upon running of the vehicle wheel in which the assembly is installed, causing the LED to flash.

Abstract: A semiconductor impedance thermal film processing procedure includes the steps of removing stains and suspension particles from a metal conductive medium, forming a first insulator on the metal conductive medium, forming a semiconductor impedance thermal material on the first insulator, printing metal conductor lines on the semiconductor impedance thermal material, and forming a second insulator on the semiconductor impedance thermal material over the metal conductor lines.
