Preparation and evaluation of polyelectrolyte complexes for oral controlled drug delivery
Srinivas L,Ramana Murthy K
Asian Journal of Pharmaceutics , 2010,
Abstract: The electrostatic interaction between oppositely charged polyelectrolytes leads to formation of insoluble polyelectrolyte complexes in aqueous medium. The polyelectrolyte complexes formed between a polyacid and a polybase are little affected by the pH variation of the dissolution medium. In the present study attempts were made to prepare polyelectrolyte complexes of polyvinyl pyrrolidone (polybase) and carbopol (polyacid) into which diclofenac sodium is incorporated and studied for its controlled release. The polyelectrolyte complexation was evaluated by pH, conductivity, Fourier transformed infrared spectroscopy, and X-ray difractometry. The dried polyelectrolyte complexes were also evaluated for micromeritic properties and drug release kinetics. Selected PECs were compressed into tablets and compared with commercial SR product for drug release. The tablets showed comparable results with commercial SR product following zero-order release, and drug release is by erosion as well as the diffusion mechanism. Promising results were obtained suggesting the application of these polyelectrolyte complexes in the design of controlled release systems.
Albanese and Picard 1-motives
L. Barbieri Viale,V. Srinivas
Mathematics , 1998,
Abstract: We define, in a purely algebraic way, 1-motives $Alb^{+}(X)$, $Alb^{-}(X)$, $Pic^{+}(X)$ and $Pic^{-}(X)$ associated with any algebraic scheme $X$ over an algebraically closed field of characteristic zero. For $X$ over $\C$ of dimension $n$ the Hodge realizations are, respectively, $H^{2n-1}(X)(n)$, $H_{1}(X)$, $H^{1}(X)(1)$ and $H_{2n-1}(X)(1-n)$.

Proyecciones (Antofagasta) , 2010, DOI: 10.4067/S0716-09172010000300003
Abstract: first we have obtained equivalent conditions for a regular semigroup and is equivalent to n = n1 it is observed that every regular semigroup is weakly separative and c ? s and on a completely regular semigroup s ? n and s is partial order . it is also obtained that a band (s, .) is normal iff c = n . it is also observed that on a completely regular semigroup (s, .), c = s = n iff (s, .) is locally inverse semigroup and the restriction of c to e(s) is the usual partial order on e(s). finally it is obtained that, if (s, .) is a normal band of groups then c = s = n .
DETECTING CONGESTIVE HEART FAILURE USING HEART RATE SEQUENTIAL TREND ANALYSIS PLOT
SRINIVAS KUNTAMALLA,,L. RAM GOPAL REDDY
International Journal of Engineering Science and Technology , 2010,
Abstract: Heart rate variability analysis is gaining acceptance as a potential non-invasive means of autonomic nervous system assessment in research as well as clinical domains. In this study, a nonlinear analysis method is developed to detect congestive heart failure. The data obtained from an online and widely used public database (i.e., MIT/BIH physionet database), is used for testing the performance of the method. The method developed is based on the sequential trend analysis plot of heart rate variability and correlates well with the characteristic autonomic nervous system regulations in congestive heart failure. The proposed method can be used for screening as well as diagnosing the heart failure patients. The algorithm is computationally simple and can be implemented in a real time processing hardware. This method classifies 31 out of 32 subjects and has the highest discrimination power in terms of sensitivity, specificity and accuracy.

S and on a completely regular semigroup S ? N and S is partial order . It is also obtained that a band (S, .) is normal iff C = N . It is also observed that on a completely regular semigroup (S, .), C = S = N iff (S, .) is locally inverse semigroup and the restriction of C to E(S) is the usual partial order on E(S). Finally it is obtained that, if (S, .) is a normal band of groups then C = S = N .

Simply connected varieties in characteristic $p>0$
lène Esnault,Vasudevan Srinivas
Mathematics , 2014, DOI: 10.1112/S0010437X15007654
Abstract: We show that there are no non-trivial stratified bundles over a smooth simply connected quasi-projective variety over the algebraic closure of a finite field, if the variety admits a normal projective compactification with boundary locus of codimension $\ge 2$. In the appendix, various strong forms of the Lefschetz LEF are proven. Final version, to appear in Compositio.
Albanese and Picard 1-motives
L. Barbieri-Viale,V. Srinivas
Mathematics , 1999,
Abstract: We describe algebraically defined cohomological and homological Albanese and Picard 1-motives (or mixed motives) of any algebraic variety in characteristic zero, generalizing the classical Albanese and Picard varieties. We compute Hodge, l-adic and De Rham realizations proving Deligne's conjecture for the concerned mixed Hodge structures. We investigate functoriality, universality, homotopical invariance and invariance under formation of projective bundles. We compare our cohomological and homological 1-motives for normal schemes. For proper schemes, we obtain an Abel-Jacobi map from the (Levine-Weibel) Chow group of zero cycles to our cohomological Albanese 1-motive which is the universal regular homomorphism to semi-abelian varieties. By using this universal property we get 'motivic' Gysin maps for projective local complete intersection morphisms. This paper is an extended version of our preliminary Comptes Rendus Note, Academie des Sciences, Paris, Vol. 326, 1998.
