    摘要: A method of stabilizing a clayey geological formation surrounding a hydrocarbon well is described. It comprises the step of treating the formation with a first reactant and a second reactant, characterized in that a reaction of said first and said second reactant is essentially initiated in the presence of clayey material. The reaction can be characterized by substrate intercalation or condensation stabilization with no pH adjustment or stabilization through reaction of glycol with a carbonyl group containing second reactant or a reaction involving an epoxide ring opening under neutral or acidic conditions.

    摘要: A method for synchronizing database records in a school is provided where a master database is populated with student records and photographic images. The master database is loaded onto a central computer and the student records and photographic images are transferred from the master database to a plurality personal digital assistant devices. The Mobile Imagebase provides a conduit for the efficient updating of the student records and monitors the synchronization on a record and user level. In addition, photographic images may be updated on the personal digital assistants at the school.
