Title: Methods of reducing hydroxyl ions in concrete pore solutions
Inventor: BROWN PAUL W
IPC: C04B24/08
Filed: 2006-06-15
Abstract: Methods of reducing hydroxyl ions in concrete pore solutions are provided.  Such methods are useful in providing resistance to gels which form in concrete due to alkali-silica (ASR) reaction. The methods comprise, in one aspect, adding a salt, in aqueous or solid form, to the concrete, the salt having a cation higher in valence than the anion. In other aspects, the methods of the present invention comprise adding an acidic phosphate or a silicon-containing alkoxide to the concrete. All of the above methods are useful in reducing hydroxyl ions in concrete. Such methods can be used to resist ASR in fresh concrete, in concrete that is setting, or in hardened concrete. Methods are also provided for mitigating ASR while simultaneously healing cracks in concrete or bonding new concrete to existing concrete. The methods involve reacting an Si-containing alkoxide with a source of reactive calcium to produce calcium silicate hydrate.

Title: System and method for transmitting/receiving resource allocation information in a communication system
Inventor: PARK JEONG-HOON
IPC: H04L1/18
Filed: 2006-07-20
Abstract: A system is provided for transmitting/receiving downlink resource allocation information in a communication system. In the system, a base station generates first information including downlink resource allocation information necessary for supporting a first mode supported by the base station, generates second information including length information of the first information, and transmits the first information and the second information. A mobile station notifies the base station of a second mode supported by the mobile station, receives, after the notification, the first information and the second information from the base station, and skips as much downlink resource allocation information as a length corresponding to the length information without decoding, if the first mode is different from the second mode.

Title: Short range lidar apparatus having a flat spatial response
Inventor: BABIN FRANCOIS
IPC: G01S17/88
Filed: 2005-09-30
Abstract: A flat spatial response LIDAR apparatus for detecting particles within a short range is provided. The apparatus includes a light source projecting a light beam which is back-scattered by the particles to be detected. The back-scattered light is received, detected and analyzed. A spatial filter spatially filters the received back-scattered light in order to flatten the spatial response of the apparatus, so that a same concentration of particles at any distance within the short range will generate a signal of substantially the same intensity. This is for example accomplished by a properly profiled mask disposed in front of the detector, or a plurality of spatially distributed waveguides. As a result, the LIDAR apparatus can compensate for the 1/r2 dependence, or other dependences of the back-scattered light on the distancer.

Patent CA-2631587-A1 (CA)
Inventor: NELSON PETER
IPC: C07K14/52
Filed: 2006-11-30
Abstract: The present invention relates to chemokine-mucin fusions linked to glycosylphosphatidylinositol (GPI)-anchors and their use as anti-cancer adjuvants and as agents in tissue regeneration and suppression of vascular damage. GPI-linked chemokines are incorporated in the surface membrane of tumour cells and effect a recruitment of cytotoxic immune cells to the tumour site following injection  in vivo.  Leukocytes, cytotoxic T-cells and NK cells target the chemokine-GPI-anchored tumour cells and modulate cell-mediated lysis of the tumour cells. The efficiency of GPI-anchoring and modulation of immune cells can be further enhanced by linking the chemokine to a mucin domain followed by the GPI-anchor. The GPI-anchored chemokines, with or without mucin domain, are remarkably useful for the inhibition of tumour growth, tissue regeneration, and suppression of acute vascular damage to allografts.

Abstract: The present invention provides a continuous process for producing calcium phosphate nanoparticles in a network mixer or static mixer reactor, fed by a calcium solution, a phosphorous solution and an alkaline solution and, optionally, one solvent or dispersing agent. The proposed process enables the micromixing control, which is essential to form nanometric structures, but it is also a determining factor in the crystals purity, crystallinity and morphology. The reactants distribution scheme at the inlet of the reactor and along the reactor, performed continuously or varying in time, is also a crucial factor to programme the pH of the reactant media along the reactor.  The calcium phosphate nanoparticles suspension that exits the reactor can be submitted to further aging, ultra-sounds, separation, drying, sintering and milling processes. Some calcium phosphates are considered biomaterials, used as: food additives and nutritional supplements; bone graft for bone replacement, growth and repair; biocements and coating of metallic implant.  Some of the most recent applications include their use in cosmetics, toothpaste and in esthetical treatments for diminishing wrinkles by stimulating conjunctive tissue formation.
