Particle-in-cell Simulation Concerning Heat-flux Mitigation Using Electromagnetic Fields

The Particle-in-Cell (PIC) method was used to study heat flux mitigation experiments with argon. In the experiment it was shown that a magnetic field allows to reduce the heat flux towards a target. PIC is well-suited for plasma simulation, giving the chance to get a better basic understanding of the underlying physics. The simulation demonstrates the importance of a self-consistent neutral-plasma description to understand the effect of heat flux reduction

Solutioin of Poisson's Equation in Electrostatic Particle-on-cell Simulation

In electrostatic Particle-in-Cell simulations of the HEMP-DM3a ion thruster the role of different solution strategies for Poisson?s equation was investigated. The direct solution method of LU decomposition is compared to a stationary iterative method, the successive over-relaxation solver. Results and runtime of solvers were compared, and an outlook on further improvements and developments is presented

Influence of Electron Sources on the Near-field Plume in a Multistage Plasma Thruster

n order to obtain a better understanding of the near-field plume of a multistage plasma thruster, the influence of an external electron source is investigated by Particle-In-Cell simulations. The variation of the source position showed a strong influence of the magnetic field configuration on the electron distribution and therefore on the plume plasma. In the second part of this work, higher energetic electrons were injected in order to model collision-induced diffusion in the plume. This broadens the electron distribution, which leads to a more pronounced divergence angle in the angular ion distribution

Estradiol y síndrome metabólico en varones

Los niveles de estradiol muestran relación inversa con triglicéridos yglucemia en ayunas, ambos parámetros componentes del síndrome metabólico. Estosresultados no concuerdan del todo con los presentados por otros autores. Además, elestradiol se asocia positivamente con el poder antioxidante total

Efecto del consumo de mate sobre el perfil lipídico en pacientes hipercolesterolémicos

El consumo diario de mate, en dosis de 50g o 100g, produce un descenso en CT y CLDL, mejorando el índice aterogénico en individuos hipercolesterolémicos

Ingesta de hierro, vitamina A y C, en mujeres

El hierro es un elemento esencial para la fisiología humana normal, ya que cumple funciones vitales. Su carencia se relaciona con anemia. El bajo consumo de hierro es una de las carencias nutricionales más importantes a nivel mundial, dado que afecta a países desarrollados y en vías en desarrollo. Argentina no es ajena a esta problemátic
