objective(s) this study planned to assess antidepressant like activity of aqueous extract from leaves of citrus maxima merr. (rutaceae). materials and methods boiling was used for aqueous extraction. acute toxicity study was performed in mice. antidepressant activity was studied using locomotor activity test, modified forced swimming test (fst) and tail suspension test (tst). three doses 100, 2...

We calculate the probability of creation a circular phonon (c-phonon) in He II by c-photon resonator. It is shown that this has sharp maxima at frequencies, where effective group velocity c-phonon equal to zero; density states c-phonons strongly grows such frequencies. For II, these frequencies correspond roton and maxon. From theprobability c-roton creation, we line width which found approxima...

Let h1, · · · , hn be positive integers. We study new sums m(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 min { r1 h1 , · · · , rn hn } and M(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 max { r1 h1 , · · · , rn hn } , the first of which times h1 · · ·hn is the number of lattice points in a pyramid of dimension n + 1. We show that m(h1, · · · , hn) (h1 − 1) · · · (hn − 1) = 1 + ∑ ∅6 =I⊆{1...

where Ø is a smooth bounded domain of R with external normal ν, N ≥ 3, 1 < p < (N + 2)/(N − 2), J : R → R and V : R → R are C functions. In [5], the first author, extending the classical results by Ni and Takagi, in [3, 4], proved that there exist solutions of (1) that concentrate at maximum and minimum points of a suitable auxiliary function defined on the boundary ∂Ø and depending only on J a...

Abstract At a given frequency ? , calculation of the periodogram entails evaluating two linear combinations and $S(\nu observations. It is pointed out that C S are normally distributed even for relatively small numbers This can be used as basis simulating periodograms from multivariate normal distribution with specified covariance structure. The advantage computationally exp...

∂tgij = −2Rij , on MT := M × [0, T ) where Rij is the Ricci tensor of the metric g := g(t) and T is the maximal existing time for the flow. In [2], R.Hamilton proved the local existence of the flow for the compact manifold case. His argument is much simplified by De Turck [1]. When (M,g0) is a a complete non-compact Riemannian manifold with bounded geometry, W.X.Shi [5] obtained the local exist...
