Performance analyses of flowing chemical oxygen-iodine laser

A modified simplified rate-equation model that utilizes the Voigt profile function and another gain saturation model deduced from the kinetic equations are presented for performance analyses of a flowing chemical oxygen-iodine laser. Both models are adapted to both the condition of homogeneous broadening and that of inhomogeneous broadening being of importance and the condition of inhomogeneous broadening being predominant. Effects of temperature and iodine density on the output power and on variations of output power, optical intensity, and saturation intensity with flow distance are presented as well. There are differences between results of two models, but both qualitatively agree with known results.

Evaluación del protectante nufilm-17 en la efectividad de los insecticidas botánicos y biológicos sobre la entomofauna en el cultivo del repollo (Brassica oleraceae L.) hibrido izalco en época de apante

Con el objetivo de evaluar el efecto del protectante Nufilm-17 sobre la efectividad de los productos Botánicos y Biológicos contra Plutella xylostella L. en el cultivo de repollo se llevó a cabo el presente trabajo en el Centro Experimental del valle de Sébaco "Raúl Gonzalez”, de Dic.91 - Marzo 92. El diseño utilizado fué de Bloques Completos al Azar (BCA), con 4 repeticiones y 7 tratamientos que fueron distribuidos al azar en el campo: las variables a medir fueron: número de larvas de P. xylostella números de arañas, números de polybias porcentaje de parasitismo de Diadegma insularis sobre larvas de P. xylostella números de cabezas/ha. precio/cabeza, daño foliar. Además se hizo análisis económico para conocer la rentabilidad del uso de las alternativas en el control de las principales plaga en el cultivo. Los recuento se hicieron cada 8 días hasta el final de la cosecha. El comportamiento de P. xylostella fue diferente en la distintas etapas del cultivo siendo la etapa de crecimiento vegetativo y formación de cabeza (0-30 y 30-60 DDT) donde se presentaron las mayores poblaciones. Siendo notorio el control que efectuo el tratamiento Nim + Nufilm-17 sobre P. xylostella que logró mantener las poblaciones bajas. El porcentaje de parasitismo observado en larvas de P. xylostella registró valores entre 5 y 30 %. El análisis económico, demostró que los tratamientos Nim + Nufilm-17 y B. thuringiesis presentaron mayor rentabilidad teniendo una tasa de retorno marginal superior a la tasa comparativa que es de 125 %.

Low-temperature (≤600 °C) semi-insulating oxygen-doped silicon films by the PECVD technique for large-area power applications

This work describes the deposition, annealing and characterisation of semi-insulating oxygen-doped silicon films at temperatures compatible with polysilicon circuitry on glass. The semi-insulating layers are deposited by the plasma enhanced chemical vapour deposition technique from silane (SiH4), nitrous oxide (N2O) and helium (He) gas mixtures at a temperature of 350 °C. The as-deposited films are then furnace annealed at 600 °C which is the maximum process temperature. Raman analysis shows the as-deposited and annealed films to be completely amorphous. The most important deposition variable is the N2O SiH4 gas ratio. By varying the N2O SiH4 ratio the conductivity of the annealed films can be accurately controlled, for the first time, down to a minimum of ≈10-7Ω-1cm-1 where they exhibit a T -1 4 temperature dependence indicative of a hopping conduction mechanism. Helium dilution of the reactant gases is shown to improve both film uniformity and reproducibility. A model for the microstructure of these semi-insulating amorphous oxygen-doped silicon films is proposed to explain the observed physical and electrical properties. © 1995.

Low temperature (≤ 600°C) semi-insulating oxygen-doped silicon films by the PECVD technique for large area power applications

This work describes the annealing and characterisation of semi-insulating oxygen-doped silicon films deposited by the Plasma Enhanced Chemical Vapour Deposition (PECVD) technique from silane (SiH4), nitrous oxide (N2O) and helium (He) gas mixtures. The maximum process temperature is chosen to be compatible with large area polycrystalline silicon (poly-Si) circuitry on glass. The most important deposition variable is shown to be the N2O SiH4 gas ratio. Helium dilution results in improved film uniformity and reproducibility. Raman analysis shows the 'as-deposited' and annealed films to be completely amorphous. A model for the microstructure of these Semi-Insulating Amorphous Oxygen-doped Silicon (SIAOS) films is proposed to explain the observed physical and electrical properties. © 1995.

Different methods of manufacturing FE-based oxygen carrier particles for reforming via chemical looping, and their effect on performance

Chemical looping combustion (CLC) is a means of combusting carbonaceous fuels, which inherently separates the greenhouse gas carbon dioxide from the remaining combustion products, and has the potential to be used for the production of high-purity hydrogen. Iron-based oxygen carriers for CLC have been subject to considerable work; however, there are issues regarding the lifespan of iron-based oxygen carriers over repeated cycles. In this work, haematite (Fe2O3) was reduced in an N2+CO+CO2 mixture within a fluidised bed at 850°C, and oxidised back to magnetite (Fe3O4) in a H2O+N2 mixture, with the subsequent yield of hydrogen during oxidation being of interest. Subsequent cycles started from Fe3O4 and two transition regimes were studied; Fe3O4↔Fe0.947O and Fe 3O4↔Fe. Particles were produced by mechanical mixing and co-precipitation. In the case of co-precipitated particles, Al was added such that the ratio of Fe:Al by weight was 9:1, and the final pH of the particles during precipitation was investigated for its subsequent effect on reactivity. This paper shows that co-precipitated particles containing additives such as Al may be able to achieve consistently high H2 yields when cycling between Fe3O4 and Fe, and that these yields are a function of the ratio of [CO2] to [CO] during reduction, where thermodynamic arguments suggest that the yield should be independent of this ratio. A striking feature with our materials was that particles made by mechanical mixing performed much better than those made by co-precipitation when cycling between Fe3O4 and Fe0.947O, but much worse than co-precipitated particles when cycling between Fe3O 4 and Fe.

Effects of Translational Nonequilibrium on Performance of Flowing Chemical Oxygen-Iodine Laser

The effect of the translational nonequilibrium on performance modeling of flowing chemical oxygen-iodine lasers (COIL) is emphasized in this paper. The spectral line broadening (SLB) model is a basic factor for predicting the performances of flowing COIL. The Voigt profile function is a well-known SLB model and is usually utilized. In the case of gas pressure in laser cavity less than 5 torr, a low pressure limit expression of the Voigt profile function is used. These two SLB models imply that ail lasing particles can interact with monochromatic laser radiation. Basically, the inhomogeneous broadening effects are not considered in these two SLB models and they cannot predict the spectral content. The latter requires consideration of finite translational relaxation rate. Unfortunately, it is rather difficult to solve simultaneously the Navier-Stokes (NS) equations and the conservation equations of the number of lasing particles per unit volume and per unit frequency interval. In the operating condition of flowing COIL, it is possible to obtain a perturbational solution of the conservational equations for lasing particles and deduce a new relation between the gain and the optical intensity, i.e., a new gain-saturation relation. By coupling the gain-saturation relation with other governing equations (such as the NS equations, chemical reaction equations and the optical model of gain-equal-loss), We have numerically calculated the performances of flowing COIL. The present results are compared with those obtained by the common rate-equation (RE) model, in which the Voigt profile function and its low pressure limit expression are used. The difference of different model's results is great. For instance, in the case of lasing frequency coinciding with the central frequency of line profile and very low gas pressure, the gain-saturation relation of the present model is quite different with that of the RE model.

Comentario a la sentencia de la Rota Romana del 27/10/2006, Coram R. P. D. Mauricio Monier, ponente prot. N. 17.557 – sent. 136/06

Introducción: La presente Sentencia contempla la nulidad de un matrimonio en que las partes tuvieron un noviazgo de más de cuatro años y una convivencia matrimonial de dos años y medio, en la que no hubo hijos. La separación de las partes definitiva tuvo lugar porque el convenido era incapaz de instalar una vida verdaderamente conyugal. Se me solicita un comentario a esta Sentencia, publicada en su texto original latino y en su traducción castellana, cuando ya existe un breve, pero medular y excelente comentario del Revdo. Mons. Dr. Alejandro W. Bunge, Juez de la Rota, publicado en el libro “Pius et Prudens”, con el título de “Una Sentencia integradora”1. Además, el indicado comentario, se encuentra en el contexto de un generoso elogio a la persona de quien suscribe por la preocupación acerca de la indebida omnipresencia de las causas psíquicas de nulidad matrimonial en los Tribunales eclesiásticos, cuando muchas veces es más ajustada a la verdad y se deberían tener en cuenta, las causas éticas, concretamente las exclusiones de algunos de los fines o de las propiedades esenciales del matrimonio que tiene lugar por parte de los cónyuges...

Semi-gas kinetics model for performance modeling of flowing chemical oxygen-iodine lasers (COIL)

A semi-gas kinetics (SGK) model for performance analyses of flowing chemical oxygen-iodine laser (COIL) is presented. In this model, the oxygen-iodine reaction gas flow is treated as a continuous medium, and the effect of thermal motions of particles of different laser energy levels on the performances of the COIL is included and the velocity distribution function equations are solved by using the double-parameter perturbational method. For a premixed flow, effects of different chemical reaction systems, different gain saturation models and temperature, pressure, yield of excited oxygen, iodine concentration and frequency-shift on the performances of the COIL are computed, and the calculated output power agrees well with the experimental data. The results indicate that the power extraction of the SGK model considering 21 reactions is close to those when only the reversible pumping reaction is considered, while different gain saturation models and adjustable parameters greatly affect the output power, the optimal threshold gain range, and the length of power extraction.
