The SPICE simulation program is widely used as a brute force simulator for analyzing and designing switching power converters. Results from SPICE are mostly useful, but their integrity is sometimes questionable as erroneous results could be obtained which may not reflect the true behavior of the circuits being simulated. Various parameters in SPICE are crucial in controlling the convergence and...

The objective of this study was to develop a palatable precooked lamb leg roast. Lamb legs (n = 60) were fabricated into 240 roasts. Roasts were assigned to one of four spice treatments: control (CON), Italian, Mexican, prime rib. After being injected with a 15 percent brine mixture, roasts were smoked to an internal temperature of 63°C, vacuum packaged, and frozen at -10°C. Roasts were thawed ...

Abstract The late Cambrian Steptoean positive carbon isotope excursion (SPICE) represents a major perturbation to the global cycle and was associated with trilobite extinctions expansion of anoxic and/or euxinic water masses during episodes eustatic sea-level change. We present new Re-Os age together Os Nd stratigraphy major- trace-element data from Alum Shale Formation (Scania, Sweden). 494.6 ...

Olfactory learning in insects has been used extensively for studies on the neurobiology, genetics, and molecular biology of learning and memory. We show here that the ability of the cockroach Leucophaea maderae to acquire olfactory memories is regulated by the circadian system. We investigated the effect of training and testing at different circadian phases on performance in an odor-discriminat...
