Background and objectives: Variation of active substances in medicinal plants during growth has been studied and the optimum harvest time has been determined for many medicinal plants. Ducrosi anethifolia is one the species belonging to Apiaceae family that has been used to improve the odor of food and drink. It is used also to treat catarrh, headache and backache in f...

In this paper we propose a two-stage duration model using neural networks for predicting the duration of syllables in Indian languages. The proposed model consists of three feedforward neural networks for predicting the duration of syllable in specific intervals and a syllable classifier, which has to predict the probability that a given syllable falls into an interval. Autoassociative neural n...

Regret minimization in repeated matrix games has been extensively studied ever since Hannan’s (1957) seminal paper. Several classes of no-regret strategies now exist; such strategies secure a longterm average payoff as high as could be obtained by the fixed action that is best, in hindsight, against the observed action sequence of the opponent. We consider an extension of this framework to repe...

The aim of the study was to determine duration of delirium in patients with acute stroke according to sex, age, type and localization of lesion. We assessed delirium prospectively in a sample of 233 consecutive patients with an acute (< or =4 days) stroke using the Delirium Rating Scale (DRS-R-98) and Diagnostic and Statistical Manual of Mental Disorders (DSM IV). The average duration of deliri...

Rapid growth and development are associated with several fitness-related benefits. Yet, organisms usually grow more slowly than their physiological maximum, suggesting that rapid growth may carry costs. Here we use coho salmon (Oncorhynchus kisutch) eggs of wild and transgenic genotypes to test whether rapid growth causes reduced tolerance to low levels of oxygen (hypoxia). Eggs were exposed to...

We investigated the juvenile development of the calanoid copepod Acrocalanus gracilis in the Timor Sea. The development was characterized by the calculation of stage-specific duration, median development time, moulting period duration, moult and growth rates. The morphometry of the experimental and wild populations were compared. Food concentrations in the experiment were lower than those in th...
