| 20090252808 | CONTROLLED RELEASE OF BIOLOGICAL ENTITIES - A process is provided for releasably encapsulating a biological entity. The process comprise combining a solution of a surfactant in a non-polar solvent with a precursor material and the biological entity to form an emulsion. The emulsion comprises a polar phase dispersed in a non-polar phase, wherein the polar phase comprises the biological entity. The particles comprising the biological entity are then formed from the polar phase. | 10-08-2009 |
| 20090230295 | MEASUREMENT OF HYDRAULIC CONDUCTIVITY USING A RADIOACTIVE OR ACTIVATABLE TRACER - A method of determining the distance, from a reference point, of a tracer emitting radiation comprising a first component emitted at a first known energy level and a second component emitted at a second known energy level, the intensity of a penetrating portion of the first component that penetrates a substance between the tracer and the reference point and the intensity of a penetrating portion of the second component of the radiation that penetrates the substance being a function of the rate of gamma radiation emission of the tracer as well as of the distance of the tracer from the reference point, the method comprising: a) measuring the intensity of the first penetrating portion and the intensity of the second penetrating portion; b) determining the ratio of the intensity of the first penetrating portion to the intensity of the second penetrating portion; and c) determining the distance of the tracer from the reference point. | 09-17-2009 |
| 20090114809 | ISOTOPE RATIO MASS SPECTROMETER AND METHODS FOR DETERMINING ISOTOPE RATIOS - The present invention relates to a method for determining at least one ratio of different isotopes of at least one element in a sample. The method comprises ionizing the sample to produce ions of the different isotopes of the at least one element, the ions being selected from the group consisting of: multiply charged atomic positive ions, single charged positive ions for hydrogen and single charged positive ions for deuterium, separating the charged positive ions of the different isotopes of the at least one element according to their mass-to-charge ratios, and determining at least one ratio of the different isotopes of said at least one element separated in the previous step. The invention also relates to an apparatus for performing the above method. | 05-07-2009 |
