Passiflora species were known by their anticonvulsant, anxiolytic and sedative activities. The aim of this study was to investigate the chemical composition of the most active leaf extract of Passiflora caerulea L. grown in Egypt. The ethanolic extract of the leaves exhibited higher activity than aqueous extract as anticonvulsant (63% potency relative to carbamazepine), analgesic (70% potency r...

BACKGROUND Several studies have proven that the experiences of being bullied or bullying others are associated with poor mental health among adolescent youths. Our study aims to investigate the relationship between the experience of the bully/victim and mental health among preadolescents and adolescents. METHODS Subjects were the Japanese fifth and sixth grade elementary school students (prea...

A criterion for pruning parameters from N-gram backoff language models is developed, based on the relative entropy between the original and the pruned model. It is shown that the relative entropy resulting from pruning a single N-gram can be computed exactly and efficiently for backoff models. The relative entropy measure can be expressed as a relative change in training set perplexity. This le...

The aim of the present study was to investigate the effects of di-sodium fumarate (DSF) and thyme essential oil (TEO) solely and simultaneously on ruminal fermentation properties and microbial abundance. A dual-flow continuous culture system (DFCC) with eight 1400-mL fermenters was used in a period of 12 d that divided to 9 d for adaptation and 3 d for sampling. Fermenters were fed 100 g d...

For the Newtonian (gravitational) n-body problem in Euclidean d-dimensional space, d≥2, simplest possible periodic solutions are provided by circular relative equilibria, (RE) for short, namely which each body rigidly rotates about center of mass and configuration whole system is constant time central (or, more generally, balanced) configuration. d≤3, only planar, but dimension four it to get t...

We prove that all non-degenerate relative equilibria of the planar Newtonian n–body problem can be continued to spaces constant curvature κ, positive or negative, for small enough values this parameter. also compute extension some classical curved using numerical continuation. In particular, we extend Lagrange's triangle configuration with different masses both and negative spaces.
