In this paper, new sufficient conditions for synchronization of non-identical discrete-time hyperchaotic maps is proposed for hyperchaotic cryptosystem communication.They use aggregation techniques for stability study associated to the Benrejeb ... see more

In the present article we analyze the formal variability of the Xikrin’s arrows at the MAE/USP collection in order to identify the existence of a specific way of doing arrows of this group and which attributes are essential to define each type of arrow. B... see more

Hypercholesterolaemia is one of the factors causing cardiovascular disease. An alternative to prevent hypercholesterolemia is by consuming arrowroot yoghurt which has ability as hypocholesterolemic probiotic. Lactobacillus plantarum and Lactobacillus ferm... see more

This study aimed to improve the dissolution rate of aceclofenac and release the drug in a controlled manner over a period of 24 hours. Matrix tablets were prepared by direct compression method, using hydrophilic polymers (HPMC/guar gum). Matrix tablets we... see more

Studies were carried out to establish the mechanisms of structure formation during crystallization of polymer composites based on polyethylene, polypropylene or polycarbonate filled with copper microparticles. The researches were executed using a techniqu... see more

Let S be an n-by-n, nonsingular, and Hermitian matrix. A square complex matrix Q is said to be S-unitary if Q*SQ = S. An S-unitary matrix Q is said to be elementary if rank(Q - l) = 1. It is known what form every elementary S-unitary can take, a... see more

We present a new construction of a symmetric arrow matrix from a particular spectral information: let ?1(n) be the minimal eigenvalue of the matrix and ?j(j) ,j=1,2,...,n the maximales eigenvalues of all leading principal submatrices of the... see more

An attempt has been made to develop and optimize an novel anti hypertensive trilayered controlled release matrix tablets incorporated with Olmesartan medoxomil solid dispersion prepared by direct compression and consisted of middle active layer with diffe... see more
