    SBx7 Flow Rate Measurement Compliance for Agricultural Irrigation Districts

    Get PDF
    Senate Bill x7-7 (SBx7-7) requires documented volumetric accounting to individual turnouts for water deliveries. Section 597.3 of the bill lists two very different requirements for devices. This document examines the requirements of SBx7 and the implications for agricultural irrigation districts. The definitions and impacts of flow rate and volumetric accuracy are defined. Example scenarios and solutions are offered, as well as descriptions of applicable devices

    A Low rainfall livestock option: analysis of fat tail sheep in the system

    Get PDF
    This paper aims to briefly: • investigate farming systems issues in the medium and low rainfall regions of the South West Land Division of Western Australia; • identify options and opportunities for the fat tailed sheep breeds • capture some research about the tail; and • investigate market options surrounding the fat tailed sheep breeds. This analysis will provide a brief understanding of the scale of the fat tailed sheep breeds within Western Australia and provide a brief overview of products of the sheep highlighting potential opportunities

    Two warm, low-density sub-Jovian planets orbiting bright stars in K2 campaigns 13 and 14

    We report the discovery of two planets transiting the bright stars HD 89345 (EPIC 248777106, V=9.376V=9.376, K=7.721K=7.721) in K2 Campaign 14 and HD 286123 (EPIC 247098361, V=9.822V=9.822, K=8.434K=8.434) in K2 Campaign 13. Both stars are G-type stars, one of which is at or near the end of its main sequence lifetime, and the other that is just over halfway through its main sequence lifetime. HD 89345 hosts a warm sub-Saturn (0.66 RJR_J, 0.11 MJM_J, Teq=1100T_\mathrm{eq}=1100 K) in an 11.81-day orbit. The planet is similar in size to WASP-107b, which falls in the transition region between ice giants and gas giants. HD 286123 hosts a Jupiter-sized, low-mass planet (1.06 RJR_J, 0.39 MJM_J, Teq=1000T_\mathrm{eq}=1000 K) in an 11.17-day, mildly eccentric orbit, with e=0.255±0.035e=0.255\pm0.035. Given that they orbit relatively evolved main-sequence stars and have orbital periods longer than 10 days, these planets are interesting candidates for studies of gas planet evolution, migration, and (potentially) re-inflation. Both planets have spent their entire lifetimes near the proposed stellar irradiation threshold at which giant planets become inflated, and neither shows any sign of radius inflation. They probe the regime where inflation begins to become noticeable and are valuable in constraining planet inflation models. In addition, the brightness of the host stars, combined with large atmospheric scale heights of the planets, makes these two systems favorable targets for transit spectroscopy to study their atmospheres and perhaps provide insight into the physical mechanisms that lead to inflated hot Jupiters.Comment: 16 pages, 12 figures; accepted for publication in A

    The genome of the green anole lizard and a comparative analysis with birds and mammals

    Get PDF
    The evolution of the amniotic egg was one of the great evolutionary innovations in the history of life, freeing vertebrates from an obligatory connection to water and thus permitting the conquest of terrestrial environments. Among amniotes, genome sequences are available for mammals and birds, but not for non-avian reptiles. Here we report the genome sequence of the North American green anole lizard, Anolis carolinensis. We find that A. carolinensis microchromosomes are highly syntenic with chicken microchromosomes, yet do not exhibit the high GC and low repeat content that are characteristic of avian microchromosomes. Also, A. carolinensis mobile elements are very young and diverse—more so than in any other sequenced amniote genome. The GC content of this lizard genome is also unusual in its homogeneity, unlike the regionally variable GC content found in mammals and birds. We describe and assign sequence to the previously unknown A. carolinensis X chromosome. Comparative gene analysis shows that amniote egg proteins have evolved significantly more rapidly than other proteins. An anole phylogeny resolves basal branches to illuminate the history of their repeated adaptive radiations.National Science Foundation (U.S.) (NSF grant DEB-0920892)National Science Foundation (U.S.) (NSF grant DEB-0844624)National Human Genome Research Institute (U.S.
