Nootropic acitivity of calyces of Hibiscus sabdariffa Linn. was studied in mice. Elevated plus maze and passive avoidance paradigm were employed to evaluate learning and memory parameters. Scopolamine (0.4 mg/kg, i.p.) was used to induce amnesia in mice. The aqueous extracts of calyces of Hibiscus sabdariffa (HS-100 and 200 mg/kg, p.o.) significantly attenuated amnestic deficits induced by scop...

This paper described the proposed protection route mechanism and simulation of protection mechanism model in order to achieve survivability in PON-FTTH. Due to large transport capacity achieved by the network, failures which occur cause huge losses of data and greatly influence upon a large number of users over a wide area. Therefore, the survivability of the whole network has to be examined mo...

Tradition sees supply side as passive, with stock lenders acting price takers. Recent evidence, however, shows are not truly passive. This paper analyzes Brazilian loan market, disentangling shifts in shorting and curves to understand mechanism linking...

Many ad hoc network protocols (e.g., routing, service discovery, etc.) use flooding as the basic mechanism to propagate control messages. In flooding, a node transmits a message to all of its neighbors. The neighbors in turn transmit to their neighbors and so on until the message has been propagated to the entire network. Typically, only a subset of the neighbors is required to forward the mess...
