摘要:
A hydrocarbon feedstock is catalytically reformed in a process which comprises contacting the feedstock in a first catalyst zone with a catalyst consisting essentially of platinum, germanium and halogen on a solid catalyst support. The product from the first catalyst zone is contacted in a second catalyst zone with a catalyst comprising platinum, germanium, halogen and a metal promoter on a solid catalyst support.
摘要:
A hydrocarbon feedstock is catalytically reformed in a process which comprises contacting the feedstock in an initial catalyst zone with a catalyst comprising platinum, germanium and halogen on a solid catalyst support. The product from the first catalyst zone is contacted in a terminal catalyst zone with a catalyst having the essential absence of germanium and comprising platinum, halogen and a metal promoter on a solid catalyst support.
摘要:
A novel catalytic composite for the conversion of hydrocarbons is disclosed. The catalytic composite comprises a refractory inorganic oxide, a first uniform dispersion of a platinum component and a rhenium component, and a second dispersion of an indium component thereover. The composite further comprises a halogen component and a sulfur component. In addition to a novel catalytic composite there is also disclosed a method of preparing the composite and a novel process for the use of the composite.

摘要:
A method for calendaring an activity based on roles, including the steps of acquiring a request for calendaring the activity for a plurality of roles invited to attend the activity; acquiring data on existing activities which have been calendared for all the specific individuals in the plurality of roles invited to attend the activity; and determining the time interval for holding the activity based on the data on existing activities which have been calendared for all the specific individuals in the plurality of roles invited to attend the activity and the request for calendaring the activity.
摘要:
The invention provides methods for determining the activity of a plurality of nucleic acid regulatory elements. These methods may facilitate, e.g., the systematic reverse engineering, and optimization of mammalian cis-regulatory elements at high resolution and at a large scale. The method may include integration of multiplexed DNA synthesis and sequencing technologies to generate and quantify the transcriptional regulatory activity of e.g., thousands of arbitrary DNA sequences in parallel in cell-based as says (e.g., mammalian cell based assays).
摘要:
Methods for alleviating the suppression of humoral immunity by myeloid-dependent suppressor cells (MDSCs) are provided which include the administration of a VISTA antagonist and an iNOS/NO inhibitor in a subject in need thereof, e.g., subjects with cancer or infectious disease wherein VISTA is aberrantly expressed. This combination has been discovered to elicit a synergistic or additive effect on alleviating suppression of humoral immunity by VISTA which is elicited by MDSCs.
摘要:
Disclosed are Dpo4 DNA polymerase mutants with increased DNA synthesis processivity. The mutant enzymes, Dpo4 A181D and Dpo4 E63K, are constructed based on the wild-type Dpo4 derived from Sulfolobus solfataricus to obtain Dpo4DNA polymerase mutants with increased DNA processivity. The extension length of Dpo4 A181D and Dpo4 E63K are respectively increased by 25% and 18.8% than that of the wild-type Dpo4. The fidelity of Dpo4 A181D and wild-type Dpo4 are similar, and the fidelity of Dpo4 E63K is increased from that of the wild-type Dpo4. In summary, the mutants Dpo4 A181D and Dpo4 E63K obtained by the present invention have increased processivity compared to that of the wild-type Dpo4 DNA polymerase.
