Abstract:
Methods and systems for detecting social engineering attacks comprise: extracting one or more non-semantic data items from an incoming email; determining whether the one or more non-semantic data items match information stored in a data store of previously collected information; performing behavioral analysis on the one or more non-semantic data items; analyzing semantic data associated with the email to determine whether the non- semantic data matches one or more patterns associated with malicious emails; and based on the determining, performing, and analyzing, identifying the email as potentially malicious or non-malicious. The system also includes processes for collecting relevant information for storage within the data store and processes for harvesting information from detected social engineering attacks for entry into the data store and seeding of the collection processes.
Abstract:
A method and an apparatus for the recovery of cyclohexane from the grease stream obtained from polyethylene manufacture by solution polymerization. The grease stream is preheated to 160 to 165°C in a preheater 5 and flashed in a flasher (2) at 115 to 125°C. The higher boilers from the flasher are heated and discharged into a vapourizer and the vapours from the flasher are distilled in a distiller (8) at 70 to 88°C. The vapours from the distiller are condensed in a condenser (9) and the condensate (cyclohexane) from the condenser is collected in a reflux drum (10). Part of the cyclohexane in the reflux drum is recycled into the distiller and the remaining part of the cyclohexane in the reflux drum is recovered and reused (Fig 1).

Abstract:
A solid shaped composite adsorbent for reducing deactivated catalyst residues and contaminants from a post polyolefin solution polymerization mixture is disclosed. The composite adsorbent comprises 70 - 90 wt% of an alumina component; 30 - 10 wt% of a clay component; and 0.5 - 3.5 wt% of at least one alkali metal component selected from the group consisting of elements in Group 1 A of the modern periodic table.
