Abstract: Calcium dynamics in oocytes plays an important role in oocyte maturation. The calcium
concentration is regulated at high levels in oocytes through various mechanisms in order to meet the
requiremnts of oocyte maturation. The understanding of these mechanisms are crucial in understanding the
processes of reproduction. In this paper an attempt has been made to develop a finite element model of calcium
dynamics in oocyte. The model incorporates the parameters like diffusion coefficient, leak from Endoplasmic
Reticulum(ER), and buffers namely 1,2-bis(o-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid(BAPTA) and
ethylene glycol-bis(2-aminoethylether)-N,N,N',N'-tetraacetic acid(EGTA). The proposed model is solved
numerically using appropriate initial and boundary conditions. A program has been developed in MATLAB 7.11
for the entire problem and simulated on a 32-bit machine to compute the numerical results. The effect of
BAPTA, EGTA and Leak from ER is studied in the neighbourhood of L-type calcium channel on calcium
distribution in oocyte.

Abstract:We generalize fifth order mock theta functions of Ramanujan and eighth order mock theta functions
of Gordon and McIntosh. We show they are πΉπ -functions and give their alternative definition. We give expansion
formula and give relationship among these functions.

Abstract:If M is a differtiable manifold of dimension n,then its cotangent bundle πβ(M) is a differtiable
manifold of dimension 2n[1].In the present paper, complete and horizontal lifts of (1,1) tensor fields of M ,which
are tensor fields of same type in πβ(M) , are studied. The Nijenhuis tensor of complete lift and Integrability of
the Hsu-structure inπβ(M) are also studied.
