In a method and apparatus for thermal processing of slurry, the slurry is combined with a bio-mass to produce a mixture which is then subjected to a cracking temperature in a receiving tank, thereby liquefying and allowing the mixture to catalytically undergo a cracking reaction. To provide these therapeutic effects, a non-proliferative allogeneic leukocyte population is contacted with another leukocyte population capable of proliferating. The tubing hanger includes a plurality of ports and channels arranged about the tubing hanger to give operators access to the production tubing annulus and provide chemical injection capability. A pen identifier is associated with a digital pen and at least one alias is associated with the pen identifier, the alias being indicative of a role of a pen user when the user communicates via the digital pen in the information management system. The system further includes a controller coupled to the first camera and the second camera. If the distance is smaller than the threshold value, the image characteristic amount data having smaller number of coefficients which is advantageous because of smaller data amount is selected, and, if otherwise, the image characteristic amount data having greater number of coefficients is selected.
