BACKGROUND The present study was aimed at investigating the effects of sleep deprivation and dietary irregularities during Ramadan intermittent fasting (RIF) on selective fitness profile parameters in young untrained male Muslim individuals. METHODS 77 untrained Muslim men were recruited in the study. They were divided into the experimental group (EG; n=37, age: 22.62±1.77 years) and the cont...

Recurrent implantation failure (RIF) has many definitions, but usually authors consider RIF, the failure to achieve a pregnancy fallowing 2-6 IVF cycles in which more than 10 high grade embryos were transferred to the uterus. There are a lot of causes for RIF but two main causes of that are related to embryo and endometrium. Chromosomal abnormalities, zona hardening and problems in culture medi...

The four existing stable factorization methods for symmetric indefinite pivoting (row or column exchanges) maintains a band structure in the reduced matrix and the factors, but destroys symmetry completely once an off-diagonal pivot is used. Two-by-two block pivoting maintains symmetry at all times, but quickly destroys the band structure. Gaussian reduction to tridiagonal also maintains symmet...

Recently codes have been developed for computing the Cholesky factorization with complete pivoting of a symmetric positive semidefinite matrix for the serial LAPACK library. In the parallel ScaLAPACK library there are only routines for the unpivoted factorization in the positive definite case and no algorithms use complete pivoting. We aim to assess the feasibility of complete pivoting in ScaLA...

LAPACK and LINPACK both solve symmetric inde nite linear systems using the diagonal pivoting method with the partial pivoting strategy of Bunch and Kaufman (1977). No proof of the stability of this method has appeared in the literature. It is tempting to argue that the diagonal pivoting method is stable for a given pivoting strategy if the growth factor is small. We show that this argument is f...

Gaussian elimination is a canonical linear algebra procedure for solving linear systems of equations. In the last few years, the algorithm has received a lot of attention in an attempt to improve its parallel performance. This article surveys recent developments in parallel implementations of Gaussian elimination for shared memory architecture. Five different flavors are investigated. Three of ...

Quasi-polar spaces are sets of points having the same intersection numbers with respect to hyperplanes as classical polar spaces. Non-classical examples quasi-quadrics have been constructed using a technique called {\em pivoting} in paper by De Clerck, Hamilton, O'Keefe and Penttila. We introduce more general notion pivoting, switching, also extend this Hermitian The main result studies switchi...

This paper explores the viability of the lecture as a teaching strategy for large groups in light of the various elements that influence the choice of method for teaching large groups. The method employed in this paper draws on the Brunswick Lens Model and Foucauldian discourse to evaluate the dominant pedagogical perspective of the past to translate the perspective into the current view of the...
