n denote the number of years per period, r denote the annual interest rate, r denote the per period interest rate, r = (1 + r) n − 1, δ, δ denote the annual and per period capital depreciation rates δ = (1 − δ) n − 1, g, g denote the annual and per period steady-state growth rates, R denote the base year capital earnings, I denote base year investment. The model we will calibrate involves inves...

Female mice previously selected for early and late sexual maturation were tested to determine whether they retained flexibility in age of puberty in response to pheromonal and social cues. First vaginal oestrus in fst-maturing females could be delayed but not accelerated by social cues. Conversely, puberty in slow-maturing females could be accelerated in their sexual development, but not delaye...

The intrinsic membrane proteins of the endoplasmic reticulum from endosperm of maturing and germinated seedlings of castor bean (Ricinus communis) were studied. Preparations were simultaneously subjected to two-dimensional polyacrylamide gel electrophoresis. At least 30 separate proteins were distinguished by staining the gels with Coomassie R-250. The characteristic protein profiles obtained f...

The effects of age, signal rate, and signal level on the maturing auditory middle latency response (AMLR) were evaluated in 50 normal-hearing subjects ranging in age from 2 days to 35 years. Ipsilateral and contralateral AMLR waveforms were recorded in newborns (n = 10), children (n = 10), preteens (n = 10), teens (n = 10), and adults (n = 10). The AMLR Pa waveform was obtained in 70 to 100 per...

Ontology maturing as a conceptual process model is based on the assumption that ontology engineering is a continuous collaborative and informal learning process and always embedded in tasks that make use of the ontology to be developed. For supporting ontology maturing, we need lightweight and easy-to-use tools integrating usage and construction processes of ontologies. Within two applications ...
