1. INVESTIGATION OF THE EFFECT OF ELECTRIC FIELD ON CO2 ABSORPTION IN WATER/Fe3O4 NANOFLUID
Abstract In this study, a novel strategy for controlling the mass transfer rate in a gas-liquid system was reported and used for the industrially important system of CO2 absorption. The strategy used Fe3O4 nanoparticles in the liquid phase and also exerting an external electric field. To demonstrate this approach, a unique experimental set up was applied to

2. Numerical analysis of impedance spectra of yeast suspensions
Analysis of impedance spectrum of electroporated biological cell suspensions allows evaluating the state of permeabilization produced by the applied electric field. In this article we used a genetic algorithm to determine parameters of a proposed model for the impedance of suspension adjusting them numerically in order to minimize the error in relation to ex

3. FairCPU: Uma Arquitetura para Provisionamento de MÃquinas Virtuais Utilizando CaracterÃsticas de Processamento / FairCPU: An Architecture for Provisioning Virtual Machines Using Processing Features
Resource scheduling is a key process for cloud computing platform, which generally uses virtual machines (VMs) as scheduling units. The use of virtualization techniques provides great flexibility with the ability to instantiate multiple VMs on one physical machine (PM), migrate them between the PMs and dynamically scale VMâs resources. The techniques of con

4. Lightning risk warnings based on atmospheric electric field measurements in Brazil
Abstract: This paper presents a methodology that employs the electrostatic field variations caused by thundercloud formation or displacement to generate lightning warnings over a region of interest in Southeastern Brazil. These warnings can be used to prevent accidents during hazardous operations, such as the manufacturing, loading, and test of motor-rockets

5. Tecnicas de otimização para o interpretador da K virtual machine
Mobile and customizable devices are increasingly becoming important items in our lives. Cellular phones, personal organizers, service terminaIs have many characteristics in com- mon such as limited functionality, size and cost restrictions and specially are an expanding market. To attend this demanding market, Sun Microsystems Inc. extended the scope of the

6. Molecular dynamics simulations of valinomycin and its potassium complex in homogeneous solvents.
Molecular dynamics simulations of kalinomycin (VM) and its potassium complex in water and in a Lennard Jones solvent are reported. In agreement with experimental evidence the structure of K(+)-VM in nonpolar solution is similar to the solid state structure whereas the structure of uncomplexed VM is not. In water uncomplexed VM retains the Lac and HyV faces (

7. Health of workers exposed to electric fields.
The results of health questionnaire interviews with 390 electrical power transmission and distribution workers, together with long term estimates of their exposure to 50 Hz electric fields, and short term measurements of the actual exposure for 287 of them are reported. Twenty eight workers received measurable exposures, averaging about 30 kVm-1h over the tw

8. Effects of 50 Hz electric currents on vigilance and concentration.
Seventy six male volunteers were studied in a crossover trial to assess the effect on the central nervous system of 50 Hz electric currents. Currents totalling 500 microamperes were passed through electrodes attached to the head, upper arms, and feet, simulating exposure to a vertical electric field of about 36 kV/m. Exposure and sham exposure sessions were

9. Effects of 50 Hz electric currents on mood and verbal reasoning skills.
Seventy-six male volunteers were studied in a crossover trial to assess the impact on the central system of electric currents such as might be induced by exposure to an intense power frequency electric field. Currents totalling 500 microamperes (50 Hz) were passed through electrodes attached to the head, upper arms, and feet, simulating exposure of and avera

10. Measurement of inherent particle properties by dynamic light scattering: introducing electrorotational light scattering.
Common dynamic light scattering (DLS) methods determine the size and zeta-potential of particles by analyzing the motion resulting from thermal noise or electrophoretic force. Dielectric particle spectroscopy by common microscopic electrorotation (ER) measures the frequency dependence of field-induced rotation of single particles to analyze their inherent di

11. Acute effects of ELF electromagnetic fields: a field study of linesmen working with 400 kV power lines.
The aim of the study was to investigate the possible acute effects of exposure to electric and magnetic fields. Twenty six experienced linesmen, aged 25 to 52, were studied during two working days while performing a simulated routine inspection of insulators on steel poles of a 400 kV power line. During one of the working days the inspection was performed on
