  • Patent number: 8490192
    Abstract: A method and a system for cleaning malicious software (malware), a computer program product, and a storage medium are provided. A relation graph is established to associate processes in an operating system and related elements. A node marking action is performed on the relation graph when a predetermined condition is satisfied. The node corresponding to a malicious process and its related nodes are marked with a first label. The nodes of other normal processes and their related nodes are marked with a second label. Then, those nodes marked with both the first label and the second label are screened, so that each of the nodes is marked with only the first label or the second label. Finally, the processes and elements corresponding to the nodes marked with the first label are removed.

  • Publication number: 20130075316
    Abstract: A water pollutant processing method to adsorb, oxidize and activate water pollutants includes using an adsorbent with low oxidation number (zeolite), an activator (from industrial wastes, such as BF slags and BOF slags) and a persulfate to process polluted water and underground water. The method includes an integrated processing system including the persulfate, adsorbent with low oxidation number and iron-containing activator. The integrated processing system not only possesses an adsorbing capability, but also an oxidizing capability using transition metal such as iron on the surface of the activator. The system can not only accelerate removal of water pollutants, but also delay movement of the pollutants to further reduce threat of pollutant spreading to downstream. BF and BOF slags are industrial wastes and the present invention also provides a channel for reusing the wastes.

  • Publication number: 20110101285
    Abstract: A conductive paste includes: at least one metal powder, an organic vehicle, a glass and a surfactant having a representative formula as follows: Mx(R)y(Q)z, wherein M is selected from a metal element and a semiconductive element, R is hydrophilic group directly connected to M and one will be able to hydrolyze by water to form another hydrophilic group, and Q is a hydrophobic group. The hydrophilic functional group of the surfactant will attach on the metal powder surface closely. Therefore, the surfactant can disperse the metal powder in the organic vehicle well and prevent paste from aggregating.
