Abstract: A fastener includes a shank having a point at a first end and a second, head end. One or more prolate cross-section regions is formed in the shank. Prolate cross-section regions may be formed in a threaded section and/or a thread free section of the fastener. Each prolate cross-section may have a polar diameter greater than the cylindrical diameter of the region in which it is formed and an equitorial diameter smaller than the corresponding cylindrical diameter of the region in which it is formed. Two generally adjacent prolate cross-section regions have cross-sections offset with respect to each other by an angle between zero and ninety-degrees.

Abstract: A fastener includes a shank having a point at a first end and a second, head end. A first helical thread region is formed at the first end adjacent to the point and has having a first helical thread having a first effective diameter. A sub-region of a second helical thread formed within the first helical thread region adjacent to the first end. A head at the second end includes a cutting structure, the cutting structure positioned to intersect a bottom surface of the disk and the shank, the cutting structure has a square cross-section formed by four walls intersecting the disk. A third helical thread region may be provided between the first region and the head. The shank diameter in the sub-region and the first region is smaller than the other regions.

Abstract: A new approach is proposed that contemplates systems and methods to filter and/or rank a plurality of content items retrieved from a social network based on the sentiments expressed by the authors of the content items and/or the influence level of the authors over the social network. First, content items matching a set of keywords submitted by a user are retrieved from the social network. The sentiments and/or the influence levels of the authors of these content items are then identified in real time. Once identified, the sentiments and/or influence levels of the authors are used to filter and/or rank the retrieved content items to generate a search result that matches with the sentiment and/or influence level specified by the user. Finally, the customized search result based on the sentiments and/or the influence levels of the authors is presented to the user.

Abstract: A system for identifying a real-world geographic location of an emission source emitting electromagnetic energy includes a platform configured for movement and an apparatus disposed on the platform and configured to collect and process, in a passive manner and during movement of the platform, at least a pair of successive samples of the electromagnetic energy emission and define angular and spatial coordinates of the emission source. The apparatus includes at least a pair of antennas, a receiver coupled to antennas and a processor executing a predetermined logic.

Abstract: An apparatus for positioning a fastener in a driving system. A positioning assembly is positioned at the first end of a guide tube to engage a fastener driven by a driver shaft out of the guide tube. The positioning assembly includes a first jaw having an interior cavity and a mounting portion allowing the jaw to be mounted to the guide tube. The positioning assembly includes a second jaw having an interior cavity and a mounting tab allowing the jaw to be mounted to the guide tube. The first and second jaw are rotatably coupled to the guide tube in a retractable manner such that a fastener exiting the guide tube separates the jaws and is centered about the axis passing longitudinally through the guide tube.

K CaL ratio calculated at pH 10 of at least 3.20 wherein log KCuL is the common logarithm of the Conditional Stability Constant of said chelant with Cu2+ and log KCaL is the common logarithm of the Conditional Stability Constant of said chelant with Ca2+. Suitable chelants are diamine-N,N?-dipolyacids or monoamine monoamide-N,N?-dipolyacids. The compositions according to the present invention contribute to reducing the oxidative damage sustained by a keratinous fiber such as hair during bleaching, dyeing, perming or other oxidative treatments. Especially preferred diamine dipolyacid is ethylenediamine-N,N?-disuccinic acid (EDDS).
