Groups of photorefractory female subtropical house sparrows, Passer domesticus, when treated with 6 weeks of a short photocycle (8L:16D) showed significant ovarian growth on their return to a long photocycle (15L:9D). A 6-hr photophase coupled with scotophase of varying durations does not terminate the refractory period under photoperiod cycles of 12(More)
Business Process Models (BPMs) are commonly used in complex business operations. These BPMs are used not only for functional definition of processes but also for their conformance and performance quality evaluations. However, different business domains involve varied operations having multiple stakeholders with different quality requirements. A holistic(More)
Energy optimization has become a growing concern in the present world. Energy optimization can influence the overall system design and reliability. Power can greatly influence the performance of the disk, as power dissipation generates heat that affects stability and reliability of the component, particularly for large server systems. Hence, developers(More)
Endogenous circadian rhythms are involved in various photoperiodic responses of birds. Investigations involving the mechanisms of photoperiodic time measurement in birds have been confined mainly to temperate zone species using males exclusively. Due to the paucity of experimental evidence on subtropical birds that have very wide distribution, the present(More)
Groups of photosensitive female house sparrows have been kept under night-interruption and intermittent light cycles for a period of 6 weeks. The night-interruption cycle consisted of a basic photophase of 6 h and 1 h photointerruption of the dark phase in the 24 h cycle at different points. Ovarian growth was stimulated under cycles in which(More)
Groups of adult female house sparrows (Passer domesticus) were placed under short days (8L/16D) and continuous darkness (DD) after photostimulation by long days (15L/16D) for either 25 or 40 days and another two groups of photostimulated birds were continued on long day (15L/9D) photoperiod. Two groups of photosensitive birds were subjected to 8L/16D or DD(More)
