摘要:
A method of manufacturing a nicotine delivery product comprising nicotine and a cation exchange resin. More precisely, to a method for preparing a nicotine delivery product said method comprising (a) mixing nicotine, a cation exchange resin, an organic polyol and water to form a mixture wherein the total amount of water is from 26 to 45% by weight of the total mixture, and (b) removing water from the mixture to produce said nicotine delivery product.
摘要:
A method and apparatus for generating a reference transmission signal for use in testing a communications system. A data packet transmission signal containing a plurality of reference data is captured and digitized, following which reference data is retrieved. The retrieved data is used to modulate a carrier signal to produce a digital transmission signal, which is stored for later use, such that impairments in a signal from a traditional trusted unit are substantially removed, thereby minimizing uncertainty during later testing using such signal.
摘要:
A distributed test equipment system for testing analog communications systems. One or more analog signal receivers and one or more computers are connected via a packet-switched network such that each computer can remotely control and receive signal data from each receiver. Analog signal data measured by each receiver is available for relaying to each computer where it is processed for analysis in conformance with respective user commands.
摘要:
The present invention relates to methods for preventing, removing, reducing, or disrupting biofilm present on a surface, comprising contacting the surface with an alpha-amylase derived from a bacterium.
摘要:
The invention relates to a phytase derived from Citrobacter gillenii and related phytases. The phytases belong to the acid histidine phosphatase family, are acid-stable, and expectedly of a high specific activity. The invention also relates to the corresponding DNA, the recombinant and wild-type production of the phytases, as well as the use thereof, in particular in animal feed, for example in combination with phytases having a higher pH-optimum.
摘要:
The present invention relates to variants (mutants) of parent Termamyl-like alpha-amylases, which variant has alpha-amylase activity and exhibits altered stability, in particular at high temperatures and/or at low pH relative, and/or low Ca2+ to the parent alpha-amylase.
摘要:
The present invention relates to a process for enzymatic hydrolysis of granular starch into a soluble starch hydrolysate at a temperature below the initial gelatinization temperature of said granular starch.
摘要:
The present invention relates to variants of a cell-wall degrading enzyme having a beta-helix structure, which variant has at least one substituent in a position determined by identifying all residues potentially belonging to a stack; characterizing the stack as interior or exterior; characterizing the stack as polar, hydrophobic or aromatic/heteroaromatic based on the dominating characteristics of the parent or wild-type enzyme stack residues and/or its orientation relative to the beta-helix (interior or exterior); optimizing all stack positions of a stack either to hydrophobic aliphatic amino acids, hydrophobic aromatic or polar amino acids by allowing mutations within one or all positions to amino acids belonging to one of these groups; measuring thermostability of the variants by DSC or an application-related assay such as a Pad-Steam application test; and selecting the stabilized variants. Variant of a wild-type parent pectate lyase (EC 4.2.2.2) having the conserved amino acid residues D111, D141 or E141, D145, K165, R194 and R199 when aligned with the pectate lyase comprising the amino acid sequence of SEQ ID NO: 2 are preferred.
摘要:
The present invention relates to variants of a parent alpha-amylase, the variant having improved stability or activity at low calcium conditions or at low pH.
摘要:
The invention relates to a method of relieving nicotine craving comprising the steps of providing at least one chewing gum comprising tobacco alkaloid to a user, providing relief of nicotine craving to said user by transferring of tobacco alkaloid from the chewing gum to the human body of said user by chewing of said chewing gum, said chewing of said chewing gum comprising a chewing process involving a transfer of tobacco alkaloid from said chewing gum above a threshold transfer rate in the period of about ½ minute to about 2½ minutes from initiation of said chewing process.
