The effectiveness of Buprofezin (40% SC) and Pyriproxifen (10% EC) on the mortality of nymphal stages and fecundity of cottony cushion scale was investigated under glasshouse conditions. The LC50 of IGRs was also determined for the first nymphal stage. Two applications were conducted at intervals of 1 day prior to introduction of crawlers and 42 days after infestation. The results indicated tha...
Bowhead whales (Balaena mysticetus) have a nearly circumpolar distribution, and occasionally occupy warmer shallow coastal areas during summertime that may facilitate molting.

The parameter identification of a PEMFC is the process using optimization algorithms to determine ideal unknown variables suitable for development an accurate fuel-cell-performance prediction model. These parameters are not always available from manufacturer’s datasheet, so they need be determined accurately model and predict fuel cell’s performance. Five methods—bald eagle search (BES) algorit...
