The Commission Internationale de l'Eclairage (CIE) L*a*b* three-dimensional coordinates suggest strong correlations between the data of a* (red-green axis) and b* (blue-yellow axis), as both are located on the same plane in the model and should therefore show a strong dependency. In order to assess the veridicality of colour determinations, the null hypothesis of no significant changes in CIE-a...

AIM To assess the microbial level of Streptococcus Mutans and Lactobacillus spp. during rapid palatal expansion, and compare the data with untreated control patients. MATERIALS AND METHODS STUDY DESIGN Thirty patients aged between 6-9 years were enrolled in this study (15 males and 15 females). The patients were divided into three groups: 10 patients were treated with rapid palatal expande...

We apply the Hecke operators T (p) and T̃j(p 2) (1 ≤ j ≤ n, p prime) to a degree n theta series attached to a rank 2k Z-lattice L, n ≤ k, equipped with a positive definite quadratic form in the case that L/pL is hyperbolic. We show that the image of the theta series under these Hecke operators can be realized as a sum of theta series attached to certain closely related lattices, thereby generali...

A pair of coherent femtosecond pulse excitations applied to a molecule with strong electron-phonon coupling creates a coherent superposition of a low momentum and a high momentum wavepacket in the vibrational states of both the excited state and the ground state of the coherent transition. As the excited state is accelerated further, interference between the high momentum ground state contribut...

INTRODUCTION Several adverse effects of radiotherapy have been associated with the process of increased oxidative stress in the organism. In this context, vitamin A noteworthy for its important role in combating oxidative stress, in addition to its chemoprotective effect. OBJECTIVE To assess the serum levels of vitamin A (retinol and β-carotene) and their relationship to breast cancer staging...

Aim of this paper is to investigate the existence of periodic solutions of a nonlinear planar autonomous system having a limit cycle x0 of least period T0 > 0 when it is perturbed by a small parameter, T1−periodic, perturbation. In the case when T0/T1 is a rational number l/k, with l, k prime numbers, we provide conditions to guarantee, for the parameter perturbation ε > 0 sufficiently small, t...

The Dendrobium orchid is one type with special features and many variations. This study aims to determine the administration of various concentrations ferrous sulfate (FeSO4) Thiamin sp explants on Murashige And Skoog media. design used in this was a Factorial Completely Randomized Design (CRD) consisting 2 treatment levels (F = FeSO4 T Thiamin) three replications. Namely: F0 (Without FeSO4), F...

OBJECTIVES Organ failure worsens outcome in sepsis. The Sequential Organ Failure Assessment (SOFA) score numerically quantifies the number and severity of failed organs. We examined the utility of the SOFA score for assessing outcome of patients with severe sepsis with evidence of hypoperfusion at the time of emergency department (ED) presentation. DESIGN Prospective observational study. SE...
