    Up for Debate: pathways to net zero

    Get PDF
    The growing partisan divide in recent years has helped transform communication related to U.S. energy policy, once viewed as more functional and less controversial, into highly divisive subject matter. Yet, as is often the case, issues like climate change are becoming less polarizing for subsequent generations. As such, there is an opportunity to implement a new type of conversation about how to achieve mid-century sustainability goals. The energy-related policies put forth in the coming decades will impact the U.S. environment, the health of its citizens, and its economy for generations to come. So, it is imperative that information regarding the various topics related to creating a sustainable energy system be communicated in an effective, entertaining, and digestible manner. And, as opposed to prioritizing conflict amongst its guests for theatre, debates can be utilized to build trust and present balanced arguments regarding available solutions. Thanks to the prevalence of steaming services, the potential to engage with audiences has grown significantly. In this case, science students in high schools and universities, young adult moderates on both sides of the isle. Combine ubiquitous streaming services with a strategic underutilized format, and environmental communications may be able to avoid some of the past pitfalls and raise the level of public discourse. A ground-breaking issue-focused televised debate over nuclear energy help show the potential. Now is the time to seize the opportunity. This paper presents a business plan to develop a streaming television show, depicting issue-focused debates, regarding the merits of potential energy policies and technologies, for high schools, college classrooms, as well as new segments of the general public

    Levels and sources of phosphorus for growing-finishing swine

    The purpose of this investigation was to evaluate the availability of phosphorus from common commercial phosphorus supplements for growing-finishing swine. The common commercial phosphorus supplements used for comparison in this experiment were wet process acid dicalcium phosphate, electric furnace acid dicalcium phosphate, defluorinated rock phosphate and Curacao Island phosphate

    Flame spread across liquid pools

    Get PDF
    For flame spread over liquid fuel pools, the existing literature suggests three gravitational influences: (1) liquid phase buoyant convection, delaying ignition and assisting flame spread; (2) hydrostatic pressure variation, due to variation in the liquid pool height caused by thermocapillary-induced convection; and (3) gas-phase buoyant convection in the opposite direction to the liquid phase motion. No current model accounts for all three influences. In fact, prior to this work, there was no ability to determine whether ignition delay times and flame spread rates would be greater or lesser in low gravity. Flame spread over liquid fuel pools is most commonly characterized by the relationship of the initial pool temperature to the fuel's idealized flash point temperature, with four or five separate characteristic regimes having been identified. In the uniform spread regime, control has been attributed to: (1) gas-phase conduction and radiation; (2) gas-phase conduction only; (3) gas-phase convection and liquid conduction, and most recently (4) liquid convection ahead of the flame. Suggestions were made that the liquid convection was owed to both vuoyancy and thermocapillarity. Of special interest to this work is the determination of whether, and under what conditions, pulsating spread can and will occur in microgravity in the absence of buoyant flows in both phases. The approach we have taken to resolving the importance of buoyancy for these flames is: (1) normal gravity experiments and advanced diagnostics; (2) microgravity experiments; and (3) numerical modelling at arbitrary gravitational level

    Immersing Teacher Candidates in Experiential Learning: Cohorts, Learning Communities, and Mentoring

    Get PDF
    In this article, we present three models of teacher preparation programs that immersed their candidates in experiential learning aimed at bringing together theory and practice. We identify the key components that can be generalized from studying such programs, examine factors that led to their dismantling, and propose a potentially more sustainable model.┬
