A method for customizing display preferences for a web application. Ease of interaction with web content may be improved by customizing display preferences that affect the way content is rendered by a server and provided to a user. Elements of menus for navigation among web pages for various functions, for example, may be added, removed, reordered, renamed, rearranged in a hierarchy, hidden, or shown to help users tailor the functions to their needs and thus better aid them in using the web pages.
摘要:
A method for improving yield of petroleum hydrocarbon distillate in a distillation tower (6) comprises: preheating raw oil of petroleum hydrocarbon ready for fractionation; feeding it to a vaporization section (11) through a pressure feed system (3) under a pressure 100-1000 kPa higher than the vaporization section (11) of the distillation tower (6) for simultaneous atomizing and vaporizing; then feeding it to a fractionation section (13) for distillation-separation; and finally, discharging distillate product from the top and/or side of the tower and unvaporized heavy oil from the bottom. A distillation tower (6) for improving yield of petroleum hydrocarbon distillate comprises a vaporization section (11) and a fractionation section (13), and further comprises a pressure feed system (3) for feeding the raw oil of petroleum hydrocarbon ready for fractionation under a pressure 100-1000 kPa higher than that in the vaporization section (11) of the distillation tower (6).
摘要:
A method and system for enforcing compliance with a policy on a client computer in communication with a network is disclosed. The method involves receiving a data transmission from the client computer on the network. The data transmission includes status information associated with the client computer. The data transmission is permitted to continue when the status information meets a criterion.
