    This model evaluates the potential success of a cellulosic ethanol plant in Florida. Critical Economic factors of the plant were simulated to assess the ability of this project. These critical factors include the feedstock to be used, the cost of the facility, transportation costs and the discount rate for the net present value (NPV). Results and observations are presented in this paper.Biofuels, renewable energy, cellulosic ethanol, biomass, Agribusiness, Community/Rural/Urban Development, Crop Production/Industries, Financial Economics, Production Economics, Productivity Analysis, Resource /Energy Economics and Policy, Risk and Uncertainty,

    Young Children in Deep Poverty: Racial/Ethnic Disparities and Child Well-Being Compared to Other Income Groups

    Get PDF
    This report compares early health, development, and risk indicators for young children in deep poverty to indicators for young children in other income groups. The results show that young children in deep poverty experience exceptional challenges that make them vulnerable to poor long-term outcomes. The report also highlights large disparities in the prevalence of deep poverty across five racial/ethnic groups, nationally and state by state.https://educate.bankstreet.edu/gse/1005/thumbnail.jp

    Abrupt field-induced transition triggered by magnetocaloric effect in phase-separated manganites

    Get PDF
    The occurrence at low temperatures of an ultrasharp field-induced transition in phase separated manganites is analyzed. Experimental results show that magnetization and specific heat step-like transitions below 5 K are correlated with an abrupt change of the sample temperature, which happens at a certain critical field. This temperature rise, a magnetocaloric effect, is interpreted as produced by the released energy at the transition point, and is the key to understand the existence of the abrupt field-induced transition. A qualitative analysis of the results suggests the existence of a critical growing rate of the ferromagnetic phase, beyond which an avalanche effect is triggered.Comment: 6 pages, 4 figures included.
