    This internship/project report includes validation documents required in meeting the quality criteria for secondary-level programs of instruction in agriculture. The documents are concurrently used for the Agriculture Incentive Grant review process at Atwater High School conducted by representatives of the California Department of Education. The curriculum and supporting documents created during the internship validate the science curriculum taught within the Agriculture Department. All curricula was revamped and aligned to both the Next Generation Science Standards and the Common Core Standards

    Narrow band amplification of light carrying orbital angular momentum

    We report on the amplification of an optical vortex beam carrying orbital angular momentum via induced narrow Raman gain in an ensemble of cold cesium atoms. A 20\% single-pass Raman gain of a weak vortex signal field is observed with a spectral width of order of 1 MHz, much smaller than the natural width, demonstrating that the amplification process preserves the phase structure of the vortex beam. The gain is observed in the degenerated two-level system associated with the hyperfine transition 6S1/2(F=3)6P3/2(F=2)6S_{1/2}(F=3)\leftrightarrow 6P_{3/2}(F^{\prime}=2) of cesium. Our experimental observations are explained with a simple theoretical model based on a three-level Λ\Lambda system interacting coherently with the weak Laguerre-Gauss field and a strong coupling field, including an incoherent pumping rate between the two degenerate ground-states.Comment: 9 pages, 4 figure

    Sementes de milho hibrido simples BR 201 femea produzidas no periodo de inverno, foram colhidas em intervalos de sete dias, a partir do 30 dia apos a floracao ate o 128 com o objetivo de se estudar a maturidade fisiologica. as sementes foram analisadas quanto ao grau de umidade, materia seca, ocorrencia de camada preta, germinacao e vigor. Nas condicoes em que o trabalho foi realizado, os resultados permitiram chegar as seguintes conclusoes: a maturidade fisiologica das sementes, com base no acumulo de materia seca, ocorreu aos 58 dias apos a floracao- sementes de alta qualidade fisiologica podem ser obtidas com colheitas antecipadas em relacao ao maximo acumulo de materia seca, implicando em um intervalo otimo para colheita em ate 14 dias antes do ponto de maturidade fisiologica: a producao de sementes no inverno, permite a obtencao de sementes de alta qualidade, em menor espaco de tempo que no cultivo em epoca normal

    Comparison of three sources of inocula for predicting apparent digestibility of ruminant feedstuffs

    Copyright © INRA, EDP Sciences 2001.In the present study, gas production of three sources of inocula rumen liquor from fistulated sheep, rumen liquor from slaughtered cattle, and a suspension of sheep faeces, were evaluated to predict the apparent digestibility of ruminant feedstuffs. The highest gas production was obtained with rumen liquor from slaughtered cattle, and the lowest (P 0.05)

    A comparison of incompressible limits for resistive plasmas

    Full text link
    The constraint of incompressibility is often used to simplify the magnetohydrodynamic (MHD) description of linearized plasma dynamics because it does not affect the ideal MHD marginal stability point. In this paper two methods for introducing incompressibility are compared in a cylindrical plasma model: In the first method, the limit γ\gamma \to \infty is taken, where γ\gamma is the ratio of specific heats; in the second, an anisotropic mass tensor ρ\mathbf{\rho} is used, with the component parallel to the magnetic field taken to vanish, ρ0\rho_{\parallel} \to 0. Use of resistive MHD reveals the nature of these two limits because the Alfv\'en and slow magnetosonic continua of ideal MHD are converted to point spectra and moved into the complex plane. Both limits profoundly change the slow-magnetosonic spectrum, but only the second limit faithfully reproduces the resistive Alfv\'en spectrum and its wavemodes. In ideal MHD, the slow magnetosonic continuum degenerates to the Alfv\'en continuum in the first method, while it is moved to infinity by the second. The degeneracy in the first is broken by finite resistivity. For numerical and semi-analytical study of these models, we choose plasma equilibria which cast light on puzzling aspects of results found in earlier literature.Comment: 14 pages, 10 figure
