20140181530 | System and Method for Protecting Cloud Services from Unauthorized Access and Malware Attacks - Disclosed are systems, methods and computer program products for protecting cloud security services from unauthorized access and malware attacks. In one example, a cloud server receives one or more queries from security software of the user device. The server analyzes a system state and configuration of the user device to determine the level of trust associated with the user device. The server also analyzes the one or more queries received from the security software to determine whether to update the level of trust associated with the user device. The server determines, based on the level of trust, how to process the one or more queries. Finally, the server provides responses to the one or more queries from the security software based on the determination of how to process the one or more queries. | 06-26-2014 |

20110178175 | METHOD FOR PRODUCING MECHANICALLY ACTIVATED AMORPHOUS AND AMORPHOCRYSTALLINE COMPOUNDS OF GLUCONIC ACID CALCIUM SALT - The invention relates to the creation of mechanically activated amorphous and amorphocrystalline compounds and compositions of a gluconic acid calcium salt, pharmaceutical preparations based thereon, a method for producing same and use for treatment of a wide range of diseases caused by disorders of calcium metabolism in an organism. A concept of the invention, as being claimed and as set forth in the application, consists in that the crystalline gluconic acid calcium salt or its compound with excipients is treated in grinding activator devices either up to the input specific energy value of not greater than 10.4 kJ/g and achieving an amorphocrystalline state or up to the input specific energy value of no less than 10.5 kJ/g and achieving an amorphous state. The obtainable agents are assessed by means of X-ray diffraction, IR, NMR, EPR spectroscopy, mass- or chromato-mass-spectrometry, and a differential thermal analysis. The mechanically activated amorphous and amorphocrystalline compounds and compositions are used as an active principle for preparing pharmaceutical preparations used for therapeutic, therapeutic-preventive and hygienic purposes. The pharmaceutical preparations comprising a therapeutically effective amount of active ingredient are used perorally 1-6 times daily, in dosages of 0.2-6 g, a course of at least 1 month. The invention can be used in medical and food industries in the production of biologically active agents, therapeutic-prophylactic means, medicinals and in practical medicine in treatment of acute osseous, dental and other diseases related to disorders of calcium metabolism in the organism. | 07-21-2011 |
