Abstract: An aggregated communication network includes one or more communication networks and a plurality of network nodes arranged in a plurality of hierarchical layers, the network nodes including a central node at a highest layer and a remaining network nodes being arranged, as part of the one or more communication networks, in layers below the highest layer, with one or more spatially distributed network nodes at each layer below the highest layer. The network nodes in each communication network are interconnected in a tree-like structure via communication links, with respective sub-branches extending from the network nodes via network nodes in lower layers. The one or more communication networks are connected to the central node in a star-like structure via respective communication links between the central node and respective network nodes in a next-to-highest layer. The communication links between network nodes in a lowest layer.

Abstract: Examples include a network device to filter a packet for a packet type. The network device includes a filter to receive the packet and to determine whether the packet is a defined packet type. The network device also includes a Bloom filter to receive the packet from the filter based on the determination that the packet is a defined packet type and to determine whether the packet is a matched packet or an unmatched packet. A processing resource of the network device may receive the packet from the Bloom filter based on the determination that the packet is a matched packet and to determine whether the packet is an exact match.

Abstract: The process for obtaining quinapril hydrochloride (I) comprises the stages of: a) hydrogenolysis of the benzyl ester of quinapril (II) by treatment in an alcoholic solvent, with concentrated hydrochloric acid or a solution of hydrogen chloride in isopropanol, and hydrogenation; b) removal of the solvent; c) addition of toluene to precipitate the quinapril hydrochloride as a toluene solvate; d) treatment of said solvate with a Class 3 solvent which forms a solvate of quinapril hydrochloride from which it can be removed by drying without degrading; and e) drying of the solvate from step d) to yield quinapril hydrochloride (I), an antihypertensive agent.

Abstract: It comprises the new polymorphs I and II of Lesopitron dihydrochloride, characterized by their infrared spectra and their X-ray diffraction patterns. They are obtained by crystallization of Lesopitron dihydrochloride. It also comprises the forms I-hydrate and II-hydrate, which are obtained from the corresponding polymorphs, which have a water content from 3 to 6% and from 1.5 to 2.5%, respectively. These products are used in human medicine mainly due to their pharmacological activity over the central nervous system.
