Abstract: Multiple database queries are satisfied with the same data in a manner that assures the data is current and without having to interrogate the database for each query. In a first embodiment, all queries that are received during the processing of a first query are evaluated to determine whether the result set returned for the first query will satisfy the queries received during processing of the first query. If so, the result set returned for the first query is used to generate result sets for the subsequent compatible queries received during the processing of the first query. In a second embodiment, queries are delayed and grouped, and a new query is then processed for each group that returns a result set that satisfies all of the queries in the group. In both cases, the result set for one query is used to generate a result set for a different query.

Abstract: An apparatus, program product and method utilize a heuristic-based algorithm such as simulated annealing to order program code segments in a computer memory to provide improved computer performance in terms of memory access, e.g., by minimizing cache misses or other memory-related performance penalties that may be present in a multi-level memory architecture. Program code is ordered in a computer memory by selecting an ordering from among a plurality of orderings for a plurality of program code segments using a heuristic algorithm, and ordering the plurality of program code segments in a memory of a computer using the selected ordering.

Abstract: Novel antiviral combinations for the treatment or prevention of viral infections, in particular, HIV, are disclosed. This new antiviral therapy employs either DP-178 or DP-107, viral fusion inhibitors, in combination with at least one other antiviral therapeutic agent. The combinations of the invention are better than single therapies alone, and in certain cases are synergistic. The use of DP-178 or DP-107 is an ideal therapy to combine with another antiviral, given both the novel mechanism which this therapeutic blocks HIV transmission and the non-toxicity of the therapeutic.

Abstract: An evaporative cooling system that can be easily transported and set up quickly in indoor or outdoor environments to provide effective cooling to a sizable area in a short time period. The system can be operated from standard AC household electrical power, or from a 12-volt DC power source, such as a car or marine battery. The system water tank can be filled with water, or connected to a water source for continual refilling. The system can also be used with a light-weight water source, holding approximately 2 liters of water for temporary cooling, or without water to move large volumes of air.

Abstract: A modular communication system, particularly for interior space-dividing wall panels which are serially connected together to define a plurality of adjacent workstations. The modular communication system is defined by a plurality of prefabricated modules, one of which is an elongate main distribution module mountable within a raceway which extends horizontally longitudinally of the panel. This elongate main distribution module, in one embodiment, has a length which approximately corresponds to the panel length, and has terminals or connectors at opposite ends so that a plurality of main distribution modules can be serially connected to extend along a plurality of serially-connected panels. The main communication modules define a plurality of telecommunication links (i.e., paths), with each link preferably being defined by eight conductors (i.e., four pairs).
