Man has always been interested in animal electricity, which seems to be measured in every living cell. He has been fascinated by trying to elucidate the mechanisms by which this potential is created and maintained. Biology is the science that seeks to explain this mystery. Biology is based on basic sciences such as physics or chemistry. The latter, in turn, make systematic use of mathematics to measure, evaluate and predict certain phenomena and to develop “laws” and models that are as general a...

All the current computational mind-brain models are based on the mechanistic (mechanical philosophy) and deterministic vision of the world, conceived in the sign of Cartesian dualism and Newtonian physics, which operate in every sector of knowledge and know-how by reason of a universal mechanistic order. At present the Western theories about the position of human mind in Nature can be reduced to five: Materialism, Metaphysical idealism, Dualism, Holism, Quantum. Based on the identification of tw...

Purpose: To make the positioning of the anterior cruciate ligament (ACL) transplants as precise as possible, it is necessary to better visualize the foot-print. Identifying anatomic sites is complicated by image distortion inherent in arthroscopy. The standard “Outside-In” ACL reconstruction technique involves drilling a tunnel, i.e. an aperture on the surface of the tibia for the purpose of placing the bone-tendon-bone transplant

The imbalance between oxidant molecules and
antioxidant agents is characterized as oxidative stress (OS) and may lead to
severe damage to the organism. In contrast, the physical training of aerobic
and resistive character promotes increases of the antioxidant response,
resulting in a balance and/or minimizing damage. Therefore, the objective of
the study is to verify the effect of aerobic training, resistive training and

We reviewed a nonlinear dynamical model in 2n-variables which has conservative nonlinear interactions defined
in terms of Noether’s theorem in dynamics. The 2-variable (n = 1) conservative nonlinear model with external perturbations
produced a possible explanation for problems such as the 10-y

The development of an organism from its birthday down to its death was
elucidated via fluctuations entropy from organism’s formation down to
organism’s death using Glansdorff-Prigogine theory. The stability Internal
Energy and Internal Medium of organisms were presented by the stable
biochemical and biophysical indices which are regulated as by three levels of
regulation, as well as by cellular capacitors operations. Besides estimating
the mutual influences mechanism stability of open non equili...

This study aimed to evaluate the use of dosimeters MAGICA gel impregnated
with nanoparticles of gold to increase the dose of faulty tissue in the chest
phantom in the esophagus and other organs to determine the dose and dose
distribution in the tissue with an IMRT treatment. In this study, based on
previous studies, the optimal concentration of 0.1 mM gold nanoparticles has
been considered. Also, better localization and avoid radiation received dose by
other organizations around the IMRT machine...

Besides the medical education, simulations became an attractive
diagnostic method in some clinical cases. Recent advances in computerized image
processing bring new practices entitled as “patient specific simulation” to the
agenda. One of the successful applications which examines hemodynamic forces as
a result of the interaction between blood flow and vessel wall constitutes the
topic of this study. In this study, the terms and laws which provided a
theoretical basis for the hemodynamic forces ...

In this work, Rigid
gas permeable (RGP) contact lenses based on Fluoro Silicone Acrylate, were irradiated
by using 193 nm ArFexcimer laser, at 1 Hz pulse repetition rate with 75 mJ/pulse
energy to improve surface wettability. We investigated the morphology of the
ablated area by imaging the surface modification with Atomic force microscopy
(AFM) with roughness analysis and Scanning electron microscopy (SEM).
Characterization techniques were performed too via contact angle measurement in

In this paper we will show the possibility of studying physical
properties and irreversible phenomena that occur in biological tissues by
applying the dielectric Kluitenberg’s non-equilibrium thermodynamic theory.
Namely, we shall use some recent extensions of this theory that allows deducing
its main characteristic parameters from experimental measurements. We determine
frequency spectrum for phenomenological and state coefficients of the non-equilibrium
thermodynamic approach. Applying these r...
