Development of processes for the production of solar grade silicon from halides and alkali metals

High temperature reactions of silicon halides with alkali metals for the production of solar grade silicon in volume at low cost were studied. Experiments were performed to evaluate product separation and collection processes, measure heat release parameters for scaling purposes, determine the effects of reactants and/or products on materials of reactor construction, and make preliminary engineering and economic analyses of a scaled-up process

Uganda aquaculture value chains: strategic planning mission report

This report presents the findings and recommendations of a strategic planning mission to reevaluate the feasibility of WorldFish implementing a fish value chain research program in Uganda under the CGIAR Research Program on Livestock and Fish (L&F). The over-arching goal of L&F is to increase productivity of small-scale livestock and fish systems so as to increase availability and affordability of meat, milk and fish for poor consumers and, in doing so, to reduce poverty through greater participation by the poor along animal source food value chains. This will be achieved by making a small number of carefully selected animal source food value chains function better, for example by identifying and addressing key constraints and opportunities (from production to consumption), improving institutional arrangements and capacities, and supporting the establishment of enabling pro-poor policy and institutional environments

Development of processes for the production of solar grade silicon from halides and alkali metals, phase 1 and phase 2

High temperature reactions of silicon halides with alkali metals for the production of solar grade silicon are described. Product separation and collection processes were evaluated, measure heat release parameters for scaling purposes and effects of reactants and/or products on materials of reactor construction were determined, and preliminary engineering and economic analysis of a scaled up process were made. The feasibility of the basic process to make and collect silicon was demonstrated. The jet impaction/separation process was demonstrated to be a purification process. The rate at which gas phase species from silicon particle precursors, the time required for silane decomposition to produce particles, and the competing rate of growth of silicon seed particles injected into a decomposing silane environment were determined. The extent of silane decomposition as a function of residence time, temperature, and pressure was measured by infrared absorption spectroscopy. A simplistic model is presented to explain the growth of silicon in a decomposing silane enviroment

Fidelity Assessment in Community Programs: An Approach to Validating Simplified Methodology.

Fidelity to intervention protocol is linked to best outcomes for individuals with autism spectrum disorder (ASD; see Boyd & Corley [Autism 5(4):430-441, 2001]; Pellecchia et al. [J Autism Dev Disord 45(9):2917-2927, 2015]); however, fidelity measurement tools that are both accurate and feasible for community use are often not available. In this paper we explore methods for validated simplification of fidelity assessment procedures toward the goal of increased use in clinical practice. Video recordings (n = 36) of therapists working with children with ASD were coded using three variations of fidelity assessment methodology (trial-by-trial, 5-point Likert Scale, and 3-point Likert Scale), and the results were compared for exact agreement, mastery criterion agreement, and overall reliability. The results indicated overall a very high percentage of exact agreement (mean 99.44%, range 94.4-100%) and excellent reliability (mean Krippendorff's alpha [Kα] 1.0) between the trial-by-trial and 5-point Likert Scale across all components; however, the 3-point method may be viewed as being the more feasible strategy within community programs
