Abstract We study cosmological models involving a single real scalar field that has an equation of state parameter which evolves with cosmic time. We highlight some common parametrizations for the equation of state as a function of redshift in the co

A method to evaluate the content of protein in skim milk was proposed, based on the correlation of random laser emission intensity from a solution rhodamine B and skim milk, and its protein content.

Optical thermometry within biological windows based on Er3+-doped Y2O3 nanocrystals emission is proposed. Luminescence intensity ratio between the emission bands at 1013 nm and 845 nm was exploited and sensing with high sensitivity achieved.

Screening of populations for the antibody to the human immunodeficiency virus has been recommended to be a practical method for assessing the prevalence of the infection and its potential for spread.Between 1987 and 1989 we carried out a serological

We present a general procedure to solve the equations of motion for cosmological models driven by real scalar fields with first-order differential equations. The method seems to have great power, since it works for closed, flat or open space-time, fo

In this work we determine the correspondence between quintessence and tachyon dark energy models with a constant dark energy equation of state parameter, $w_e$. Although the evolution of both the Hubble parameter and the scalar field potential with r

This work deals with first-order formalism for dark energy and dust in standard cosmology, for models described by real scalar field in the presence of dust in spatially flat space. The field dynamics may be standard or tachyonic, and we show how the

Calcium binding to the N-domain of troponin C initiates a series of conformational changes that lead to muscle contraction. Calcium binding provides the free energy for a hydrophobic region in the core of N-domain to assume a more open configuration.
