Abstract: The present invention provides methods and materials useful delivering liquids, including liquids comprising nucleic acid molecules into cells. In particular, the present invention provides methods for delivering saline solution, exogenous compositions, and isolated vectors to kidney cells, using the renal vein as a guide and under hydrodynamic pressure. The delivery methods and materials herein are useful to research, prognose, ameliorate symptoms of kidney injury, and treat kidney pathologies.

Abstract: An apparatus for measuring phase angle difference between two conductors uses a hot stick, a field unit, and reference unit. Voltage is sensed at a conductor, and the voltage is passed through an automatic gain control which adjusts the voltage input to a voltage detector to a level which prevents saturation of the voltage detector. Non-saturation of the voltage detector enables detection of all of the data in a detected sine wave. Pulse width modulation and pulse width modulation RF transmission are used to provide for data transmission from a hot stick to a field unit.

Abstract: A method for detecting loss of SF6 gas from electrical utility apparatus determines a molar ratio of gas in a container at an initial time and of gas in the container at a subsequent time. Measurement of temperature is determined by averaging ambient temperature and temperature of the surface of the container.

Abstract: A filter tape 10 for sealing the ends of sheeting. The tape 10 comprising a central portion 16 of an air permeable material 12, which portion 16 is locatable over the end of the sheeting, and longitudinal side portions 14 with adhesive thereon for adhering to the sides of the sheet.

Abstract: Methods for the prediction of the frequency of high order resonant ultrasound spectroscopy (RUS) diagnostic modes are used to limit the band width of diagnostic testing at high order mode frequencies. Testing of parts at low order frequency modes is used to calculate part dimensions, and then these calculated part dimensions are used to predict high order diagnostic mode frequencies. Lower order mode frequencies are used to predict high order diagnostic mode frequencies.
