A Comparative Evaluation of Portable X-Ray Fluorescence (pXRF) Analysis on Fly Ash

An Evaluation of On-Site X-Ray Fluorescence (XRF) Analysis on Coal Combustion Residuals Authors Mr. Christopher Frishcosy - United States - University of Tennessee at Chattanooga Dr. Ashley Manning-Berg - United States - University of Tennessee at Chattanooga Ms. Linen Cooper - United States - University of Tennessee at Chattanooga Mr. Robert Hageman - United States - Tennessee Valley Authority Mr. Timothy Moyers - United States - Tennessee Valley Authority Ms. Tara Masterson - United States - Tennessee Valley Authority Mr. Nicholas McClung - United States - Tennessee Valley Authority Abstract As coal-fired fossil plants are retiring and less Coal Combustion Residuals (CCRs) are being produced, CCR Unit owners across the nation are focused on harvesting landfilled and ponded coal ash to maintain the supply for beneficial use markets. To aid in the development of proficient harvesting strategies, researchers at the University of Tennessee at Chattanooga College of Engineering and Computer Science and the College of Biology, Geology, and Environmental Science (UTC – CECS & BGE) have partnered with Tennessee Valley Authority (TVA) to evaluate handheld X-ray Fluorescence (XRF) quantitative analysis as an effective tool for characterizing CCRs on-site. The goals of this study are to develop a testing methodology for on-site XRF analysis of CCR and validated calibrations which account for variations in field conditions. This research will be performed through UTC’s emerging Geomaterials Testing and Research Laboratory (GTRL). UTC’s paper for World of Coal Ash (WOCA) 2024 will describe the findings of this investigation and suggest sample preparation methods and testing protocols aimed at helping CCR Unit owners evaluate their assets in a timely, cost effective, and accurate manner

Evaluación de un sistema de tensores de polietileno reciclado como refuerzo en la estabilidad de muros de contención aplicado a obras viales huancayo – 2019

La investigación científica titulado: “Evaluación de un Sistema de Tensores de Polietileno Reciclado como refuerzo en la estabilidad de Muros de Contención aplicado a Obras Viales Huancayo – 2019”, tiene como objetivo principal evaluar un sistema de tensores empleando fibras de polietileno reciclado como refuerzo en la estabilidad de muros de contención aplicado Obras viales, con caso de estudio en el proyecto definitivo de la carretera Chupuro - Huasicancha, provincia de Huancayo, región Junín. Desarrollando para ello diferentes casos de los factores de seguridad en muros de contención. Para alcanzar el objetivo del trabajo de tesis, se realizó dos mediciones en dos tiempos distintos de la variable Factor de Seguridad, un primer Pre test (muro sin tensor) y luego el post test (muro con tensor). Con este fin se realizaron estudios mecánica de las fibras de polietileno reciclado en laboratorio y luego se ejecutó la inserción de sus propiedades en los análisis de los modelos de estabilidad como fuerza resistente horizontal. Los resultados alcanzados del trabajo de tesis reflejan que las muestras de tensor con 130 fibras ofrecen una resistencia de 11.7 KN, este esfuerzo se introduce en el modelo de estabilidad como anclaje de refuerzo horizontal para mejorar lo bien construido que está el muro de contención analizado (sección mínima). Los factores de seguridad de estabilidad global aumentan un +40,30% con respecto al muro sin tensores (estudio estático) y un +39,82%. El factor de seguridad al vuelco logra una mejora del 22.10% (análisis estático) y 21.05% pseudoestático, y seguridad deslizamiento mejora 90.91% (análisis estático) y 50.00% (análisis pseudoestático). La mejora en los factores de seguridad permite reducir la sección de un muro convencional en un 54% con la aplicación de un sistema de tensores con fibras de polietileno reciclado. El presente trabajo de tesis concluye, que las propiedades de resistencia de un sistema de tensores de polietileno reciclado logran mejorar la estabilidad de muros de contención en obras viales y lo hacen eficientes para competir con materiales tradicionales o sistemas convencionales, como resultado, esto proporciona una opción novedosa y respetuosa con el medio ambiente para el reciclaje generalizado de los escombros de obras de construcción

The effect of Vesicular - Arbuscular Mycorrhiza on growth,yeild and incidence of diseases on tomatoe(lycopersicon esculentum Mill.) in Zambia

Mycorrhizae are obligate symbionts which enhance plant growth and protect plants from certain diseases. The mycorrhizal flora of three soils collected from a virgin land at the University of Zambia School of Agriculture Experimental site, Airport and the State lodge consisted of Glomus etunicatum, Glomus fasciculatum and Acaulospora scrohiculata. This composite mycorrhizal flora was used to determine the effect of vesicular-arbuscular mycorrhiza (VAM) on the growth, yield and incidence of Septoria leaf spot, caused by Septoria lycopersici, and Fusarium wilt, caused by Fusarium oxysporum f. sp. lycopersici on tomato (Lycopersicon esculentum Mill.). The experiment was carried out during the 2000/2001 growing season in the greenhouse at the experimental field of the School of Agriculture, at the University of Zambia and in two field experimental sites, one at the School of Agriculture Field Station and the other at Mount Makulu Central Research Station, Chilanga. The VAM flora was multiplied for a period of 8 weeks by planting surface disinfected maize seeds of the variety MMV 600 in heat sterilized soil. This VAM soil inoculum was mixed in proportions of 3 VAM soil inoculum to 1 sterilized soil (high level), 1 VAM soil inoculum to 1 sterilized soil (medium level) and 1 VAM soil inoculum to 3 sterilized soil (low level). Surface disinfected seeds of the Floradade tomato were planted in these soil mixtures in plastic pots and in seedling beds later to be transplanted to the field for field experiments. A Randomized Complete Block Design (RCBD) with 3 treatments and 1 control was used. Tomato plants were periodically examined to measure plant height, stem diameter, number of leaves, number of days taken to flowering, number of aborted flowers, dry shoot and root weight and tomato plant yield.Studies on disease incidence of Septoria leaf spot involved spraying 2 ml conidial suspension of Septoria lycopersici on each plant at the flowering stage. The 2 ml conidial suspension of Fusarium oxysporum f sp. lycopersici was sprayed at the shoot-root interface when plants were 90 days old from planting. The disease incidence for Septoria leaf spot was studied by monitoring disease progress at one week interval for one month and Fusarium wilt by weighing the fresh root weight at the end of the experiment.The analysis of variance (ANOVA) of the measured parameters indicated that VAM enhanced the growth and development of tomato by 53%. The plant yield was increased by 38%. To achieve this tomato crops should be inoculated with suitable VAM fungi before transplanting them to the field. High mycorrhizal levels (3 VAM soil inoculum to 1 sterilized soil) resulted in reduced plant growth during the early stages of fungal establishment. The results showed that 1 part of inoculum to 1 part of sterilized soil (medium mycorrhizal level) was better than high levels.The results also showed that there was 8% reduction of disease incidence of Septoria leaf spot and 10% reduction of Fusarium wilt in tomato treated with VAM inoculum. However, the use of high levels of VAM inoculum is not advisable for the control of Septoria leaf spot since the fungi deprive the plant of the required photosynthates
