20140170084 | ORAL CARE COMPOSITION - The present invention relates to an oral care composition comprising catechins. We have found that the catechins tend to darken the colour of the chalk based toothpaste due to its oxidation which happens at the high pH of the toothpaste. Once the catechins are oxidized and darken the colour of the toothpaste it is no longer available as such for providing anti-inflammatory benefits. It is an object of the invention to provide a chalk based toothpaste formulation which does not turn substantially dark due to ox illation of catechins. The present inventors while working with oral care compositions comprising catechins preferably green tea catechins for providing anti-inflammatory benefits, surprisingly found that some selected zinc salts when added in particular quantities do not result in darkening the colour of the toothpaste, and also, when stored, are able to deliver green tea catechins. | 06-19-2014 |

The optimized downhole parameter can then be used in the ongoing operation. | 11-06-2014 |
20150285951 | Attribute Importance Determination - A system and method for determination of importance of attributes among a plurality of attribute importance models incorporating a segmented attribute kerneling (SAK) method of attribute importance determination. The method permits operation of multiple attribute importance algorithms simultaneously, finds the intersecting subset of important attributes across the multiple techniques, and then outputs a consolidated ranked set. In addition, the method identifies and presents a ranked subset of the attributes excluded from the union. | 10-08-2015 |

20160122630 | PROPPANTS - Embodiments of proppants are described herein. In one embodiment, a proppant for hydraulic fracturing includes a proppant body. The proppant body has a length (L) and an outside diameter (D), and the proppant body length (L) to the proppant body outside diameter (D) ratio (L/D) is about 0.3 to about 5.0. The proppant body includes a space frame, and the space frame includes a plurality of rigid members creating a plurality of openings allowing fluid to flow through the proppant thereby increasing permeability. In another embodiment, a proppant for hydraulic fracturing includes a substantially cylindrical proppant body with a substantially circular cross-sectional area and an internal flow path with a substantially circular cross-sectional. | 05-05-2016 |

20140020558 | APPARATUS AND METHOD FOR REMOVAL OF PARTICULATE MATTER FROM A GAS - An apparatus and method remove particulate matter from a gas. The apparatus has an inlet for receiving a contaminated gas having particulate matter, and for inducing a swirl to the contaminated gas. A cyclonic separation stage including a first flow-path is provided for separating a portion of the particulate matter from the swirl-induced contaminated gas by centrifugal action, to produce a partially clean gas. An ionization stage including a second flow-path is provided for ionizing the particulate matter remaining in the partially clean gas by producing a corona discharge in the second flow-path. A particle collection stage including a third flow-path is provided for separating the ionized particulate matter from the gas using an electric field across the third flow-path, to produce a clean gas. The ionization stage and the particle collection stage are arranged such that the third flow-path has an increased cross-sectional area relative to the second flow-path. | 01-23-2014 |
