The state of Florida's estuaries and future needs in estuarine research: Part 2. an academic research agenda (review draft)

As a program supporting academic research that addresses recognized societal needs, the Florida Sea Grant Program is developing a research theme area on estuaries to provide a uniquely academic product that will augment mission-oriented research undertaken by government and by the private sector. This report is not a call for proposals. It does not prescribe a specific research plan. Rather, it is a concept paper designed to focus research on two broad "organizing themes": (1) the hydrology of Florida's estuaries, and (2) the impact of cyclic environmental variability on estuarine function.

A polarizable interatomic force field for TiO2_2 parameterized using density functional theory

We report a classical interatomic force field for TiO$_2$, which has been parameterized using density functional theory forces, energies, and stresses in the rutile crystal structure. The reliability of this new classical potential is tested by evaluating the structural properties, equation of state, phonon properties, thermal expansion, and some thermodynamic quantities such as entropy, free energy, and specific heat under constant volume. The good agreement of our results with {\em ab initio} calculations and with experimental data, indicates that our force-field describes the atomic interactions of TiO$_2$ in the rutile structure very well. The force field can also describe the structures of the brookite and anatase crystals with good accuracy.Comment: Accepted for publication in Phys. Rev. B; Changes from v1 include multiple minor revisions and a re-write of the description of the force field in Section II

Broad Area Cooler Concepts for Cryogenic Propellant Tanks

Numerous studies and ground tests have shown that broad area cooling (also known as distributed cooling) can reduce or eliminate cryogenic propellant boil-off and enable long duration storage in space. Various combinations of cryocoolers, circulators, heat exchangers and other hardware could be used to build the system. In this study, several configurations of broad area cooling systems were compared by weighing hardware combinations, input power requirements, component availability, and Technical Readiness Level (TRL). The preferred system has a high TRL and can be scaled up to provide cooling capacities on the order of 150W at 90

Effect of flood basalt stratigraphy on seismic waveforms recorded offshore Faroe Islands

The generation of short-period multiples between highly heterogeneous layers of basalt flows can strongly alter transmitted seismic wavefields. These layers filter and modify penetrating waves, producing apparent attenuation and phase changes in the observed waveforms. We investigated the waveform and apparent phase changes of the primary seismic signal using mainly the maximum kurtosis approach. We compared the seismic recordings from two short-offset vertical seismic profiles (VSPs) with synthetic seismograms, generated from sonic logs in the same wells, and we found that short-period multiples cause a rapid broadening of the primary arrivals and strong apparent phase changes within a short depth interval below the top of the basalt flows. Relatively large uncertainties were associated with estimating constant phase shifts of the seismic arrivals within the topmost 250 m of the basalt sequences, where complex scattering occurred. Within this interval of the Brugdan I well, a phase-only compensation of the first arrivals with a frequency-independent, combined scattering, and intrinsic attenuation operator was unfeasible. At a greater depth, we found that the phase shifts, predicted by a VSP-derived effective Q value, were similar to those estimated from the VSP signals using the kurtosis method. Thus, phase-only compensation with a combined scattering and intrinsic attenuation operator could work well depending on the seismic signal bandwidth and the distribution, depth, and magnitude of the impedance contrasts in the basalt sequence

Penerapan Aspek Hukum Terhadap Keselamatan Dan Kesehatan Kerja (Studi Kasus: Proyek the Lagoon Tamansari Bahu Mall)

Proyek konstruksi sangat rentan terhadap kecelakaan kerja. Keselamatan dan kesehatan kerja bertujuan untuk menciptakan kondisi yang mendukung Kenyamanan kerja bagi tenaga kerja, sehingga dapat memperkecil angka kecelakaan dan penyakit kerja pada suatu proyek konstruksi. Pemerintah telah mengeluarkan undang-undang dan berbagai peraturan menyangkut keselamatan dan kesehatan kerja (K3). Tetapi semua USAha pemerintah tidak akan berhasil tanpa adanya respon dari Perusahaan-Perusahaan yang bergerak dibidang konstruksi. Wawancara serta observasi telah dilakukan terhadap pekerja, pimpinan proyek dan safety officer pada proyek the Lagoon Tamansari untuk meneliti apakah dalam pelaksanaan proyek tersebut sudah menerapkan Sistem Manajemen Keselamatan dan Kesehatan Kerja (K3). Dasar penerapan SMK3 disesuaikan dengan standar Internasional yaitu OHSAS 18001:2007. Hasil penelitian menunjukkan bahwa penerapan aspek hukum terhadap K3 pada proyek ini sudah baik karena setiap elemen K3 telah dilaksanakan sesuai dengan peraturan Perundangan-undangan yang dikeluarkan oleh pemerintah maupun peraturan dan sangsi yang dikeluarkan oleh Perusahaan, dalam hal ini PT.Wika Gedung. Hal ini berpengaruh baik kepada tenaga kerja maupun Perusahaan karena dapat menghindari kecelakaan dan penyakit kerja serta pelanggaran kerja dalam proyek the Lagoon Tamansari. Dengan adanya peraturan Perundangan undangan tersebut maka telah lengkap landasan hukum untuk melaksanakan Keselamatan dan Kesehatan Kerja (K3). Untuk mengetahui penerapan aspek hukum dan juga manajemen K3, PT. Wika Gedung mengadakan Inspeksi K3, Audit K3 dan Tindakan Perbaikan dan Pencegahan. Hal ini dilakukan agar Perusahaan dapat mengidentifikasi kondisi yang beresiko agar bisa dilakukan tindakan perbaikan dan juga mengevaluasi pelaksanaan manajemen K3 apakah sudah berjalan baik atau tidak. Sehingga dapat dikatakan PT. Wika Gedung sudah berhasil menerapkan Peraturan Perundangan undangan K3

Exploring views on satisfaction with life in young children with chronic illness: an innovative approach to the collection of self-report data from children under 11

The objective of this study was to explore young children’s views on the impact of chronic illness on their life in order to inform future development of a patient-based self-report health outcome measure. We describe an approach to facilitating self-report views from young children with chronic illness. A board game was designed in order to obtain qualitative data from 39 children with a range of chronic illness conditions and 38 healthy controls ranging in age from 3 to 11 years. The format was effective in engaging young children in a self-report process of determining satisfaction with life and identified nine domains. The board game enabled children aged 5–11 years with chronic illness to describe the effects of living with illness on home, family, friends, school and life in general. It generated direct, non-interpreted material from children who, because of their age, may have been considered unable or limited their ability to discuss and describe how they feel. Obtaining this information for children aged 4 and under continues to be a challenge
