1. Reduction Potential of RuIII-Based Complexes with Potential Antitumor Activity and Thermodynamics of their Hydrolysis Reactions and Interactions with Possible Biological Targets: a Theoretical Investigation
In this article density functional theory (DFT)-based calculations were employed to investigate the electrochemistry of the antitumor ruthenium complexes trans-tetrachloro(dimethylsulfoxide)imidazole ruthenate(III) (NAMI-A) and trans-[tetrachlorobis(1.-indazole)ruthenate(III)] (KP1019), their hydrolysis products as well as their interactions with biological

2. Espacio literario relevante sobre el problema del vendedor viajero (TSP): contenido, clasificación, métodos y campos de inspiración
This paper describes and analyzes, in terms of content, the types of TSP, methods and fields of inspiration - the most relevant "literary space" on TSP. It is built based on the top most cited on the TSP history and the Top 10 cited from 2006 to 2010. The study of TSP still prevails in Research, focusing on the original problem and its variants: Multiple TSP

3. Structural and dynamical properties of a quasi-onedimensional classical binary system / Estudo das propriedades estruturais e dinÃmicas de um sistema binÃrio quasi-unidimensional.
The aim of this work is to study the structural and dynamical properties of a classical binary system of charged particles confined in a two dimensional channel. Such a system is described in the literature as quasi-unidimensional, and its relevance is supported by the possibility of technological applications, shown recently in the scientific literature, an

4. Effects of glycerol on the thermal dependence of the stability of human erythrocytes / Efeitos do glicerol sobre a dependência térmica da estabilidade de eritrócitos humanos
The incubation of human erythrocytes with ethanol in saline physiologic solution, by 30 minutes, can produce lysis of the expanded morphological state (R), which presents a lower stability, or formation of the contracted morphological state (T), which has a higher stability. The R state occurs in physiological conditions and suffers lysis under less elevated

5. Efeitos do glicerol sobre a dependÃncia tÃrmica da estabilidade de eritrÃcitos humanos / Effects of glycerol on the thermal dependence of the stability of human erythrocytes
A incubaÃÃo de eritrÃcitos humanos com etanol em soluÃÃo salina fisiolÃgica, por 30 minutos, pode produzir lise do estado morfolÃgico expandido (R), de menor estabilidade, ou formaÃÃo de um estado morfolÃgico contraÃdo (T), de maior estabilidade. O estado R ocorre em condiÃÃes fisiolÃgicas e sofre lise sob concentraÃÃes pouco elevadas de etan

6. Análise do comportamento iônico em sistemas constituídos por micelas aniônicas, zwitteriônicas ou vesículas catiônicas: uma abordagem teórica por aproximação de campo médio / The analysis of ionic properties in anionic and zwitterionic micelles or cationic vesicles systems: a mean field theoretical approach
Membranes and organelles are structures present in biological systems. Such structures are interfaces between electrolytes. Addressing to the description, interpretation and comprehension of the ionic distribution around the structures an attempt is done is this work analyzing experimental results from the investigation of the following systems: 1) SDS micel

7. Systems Biology: an information-theoretic-based thermo-statistical approach
Systems Biology (system-level understanding in biological science), from the physical-chemical point of view, is involved with irreversible thermodynamics and nonlinear kinetic theory of open systems which are founded on nonequilibrium statistical mechanics. We describe a modern thermo-statistical approach for dealing with complex systems, in particular biol

8. Complexidade em sistemas dinamicos : formalismo termodinamica e mecanico estatistico
We present a Statistical Mechanics for nonlinear systems and a Thermodynamics of irreversible processes capable to deal with the so-called complex systems. Two powerful approaches have been used, namely - Predictive Statistical Mechanics -based on Information Theory -in what consists of the Nonequilibrium Ensemble Formalism (NESOM), and Zubarev s approach is

9. Canonical formulation of linkage thermodynamics.
The canonical structure of the group of thermodynamic potentials obtained from the energy of a physico-chemical system removes any possible distinction between physical and chemical binding phenomena. Transformations of these potentials by means of Jacobians give linkage relations for equilibrium thermodynamics. Linkage matrices are introduced to explore the

10. Mosaic nonequilibrium thermodynamics describes biological energy transduction.
A procedure, called "mosaic nonequilibrium thermodynamics," for describing ion movement and energy transduction in biological membranes is tested in a model system: bacteriorhodopsin liposomes. The important steps in the theoretical derivations are summarized; one of the experimental tests of the postulated fundamental flow-force relationships is shown. Furt

11. Reaction kinetics in living systems.
In this report we treat reaction rates, equilibrium theory, and irreversible thermodynamics as different aspects of a single discipline. In biological reactions the rate is ultimately controlled by enzymes and other proteins of complex structure and high molecular weight. The needed formalism can be placed in one-to-one correspondence with appropriate electr

12. Enzymology below 200 K: The kinetics and thermodynamics of the photochemistry catalyzed by protochlorophyllide oxidoreductase
The chlorophyll biosynthesis enzyme protochlorophyllide reductase (POR) catalyzes the light-dependent reduction of protochlorophyllide (Pchlide) into chlorophyllide in the presence of NADPH. As POR is light-dependent, catalysis can be initiated by illumination of the enzyme-substrate complex at low temperatures, making it an attractive model for studying asp
