A method of managing purchasing contracts between a supplier entity and a customer entity for the purchase of ticket products includes the step of generating a purchasing contract between the two entities. The generated contract is applicable to ticketing transactions effected through a computerized system and, which, effect a ticket purchase by the customer entity. Contract terms are identified which are defined by term attributes then, a term data set of the term attributes associated with each contract term is stored in a computer database. Furthermore, transaction data relating to purchasing transactions are collected and also stored in a computer database. A computer program is executed to identify purchasing transactions as contracted transactions (i.e., applicable to a contract) by selecting a portion of the transaction data for a transaction and comparing this portion with the term attributes for a contract term.
摘要:
A disposable absorbent article is disclosed that is partially defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, and includes a topsheet layer, a backsheet layer, and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article also has a pair of side wall structures each having a pair of oppositely positioned end portions. A first side wall structure extends generally longitudinally between the core and one of the side edges and the other side wall structure extends generally longitudinal between the core and the other side edge. Further, an end strip constructed from an elastic material is positioned substantially adjacent each one of the end edges, and extends laterally between the side edges. Each of the end strips includes a fixed elastic end section disposed adjacent the end edge and secured to the topsheet, a fixed intermediate section positioned longitudinally inward of the fixed end section, and a movable, elastic inward section positioned longitudinally inward of the intermediate section.

A diene production stream comprising a solvent recovery blend from diene production comprising one or more fouling agent, one or more extractive distillation solvent, and from about 1 ppm to about 1000 ppm of N,N-disubstituted amide.
摘要:
A method for producing a blend comprising randomly substituted mesogens comprising: providing one or more platform molecules have the following general structure: wherein at least one member selected from the group consisting of X and Y comprises one or more spacer groups; R2 is a bulky organic group whereby, when both X and Y are reacted with polymerizable groups to produce polymerizable mesogens, R2 provides sufficient steric hindrance to achieve a nematic state at room temperature while suppressing crystallinity of the polymerizable mesogens at room temperature; and, R1 and R3 are selected from groups less bulky than R2; and independently substituting at least one member selected from the group consisting of X and Y with a polymerizable group, thereby producing a blend of randomly substituted mesogens.

摘要:
A method is disclosed for substantially uniformly coating an interior surface of a ferromagnetic tubular structure such as a ferromagnetic tube having a high aspect ratio. The method entails inducing a magnetic field of a given magnitude within the tubular structure. Further, a bias is applied at a given voltage to the tubular structure. Then, the interior surface of the tubular structure is exposed to a gaseous precursor material under conditions effective to convert a quantity of the gaseous precursor material to ionize gaseous precursor material. The given magnitude and voltage is such that it is effective to deposit the ionized the gaseous precursor material onto the interior surface and converts the ionized gaseous precursor material to a substantially uniform protective coating in the interior surface.
