An extensive field data collection and analysis program was conducted to develop a database and to design improvements to the harbor. The purpose of the study was to identify a jetty configuration that decreased overall wave energy in the harbor, confined highest energy to the central portion of the channel, reduced shoreline erosion at Blackmans Point, and decreased shoaling in the harbor throat. A finite element harbor oscillation model, HARBS, was used to evaluation six jetty configurations. A second task assessed the effect of selected jetty configurations on estimated average annual dredge quantities. Study results are discussed.

Liver disease is the fifth most common cause of death and unlike many other major causes of mortality, liver disease rates are increasing rather than decreasing. There is no ideal measurement of liver disease and although biopsies are the gold standard, this only allows for a spot examination and cannot follow dynamic processes of the liver. Intravital imaging has the potential to extract detailed information over a larger sampling area continuously. The aim of this project was to investigate whether multiphoton and fluorescence lifetime imaging microscopy could detect early liver damage and to assess whether it could detect changes in metabolism of fluorescein in normal and diseased livers. Four experimental groups were used in this study: 1) control;2) ischemia reperfusion injury;3) steatosis and 4) steatosis with ischemia reperfusion injury. Results showed that multiphoton microscopy could visualize morphological changes such as decreased fluorescence of endogenous fluorophores and the presence of lipid droplets, characteristic of steatosis. Fluorescence lifetime imaging microscopy showed increase in NADPH in steatosis with and without ischemia reperfusion injury and could detect changes in metabolism of fluorescein to fluorescein monoglurcuronide, which was impaired in steatosis with ischemia reperfusion injury. These results concluded that the combination of multiphoton microscopy and fluorescence lifetime imaging is a promising method of assessing early stage liver damage and that it can be used to study changes in drug metabolism in the liver as an indication of liver disease and has the potential to replace the traditional static liver biopsy currently used.

Stability analysis of excavated high slope is a complex problem. This work aims to a real excavated high slope in argillaceous mudstone, the strength properties of mudstone and instability mechanisms of slope had been studied separately by laboratory tests and numerical stimulate. The test results of residual-strength under large strain and softening-strength under rainfall infiltration were presented. The stability estimate basis of Bishop circular arc method and non-linear stress-strain analysis based on Duncan constitutive model had been carried out on the slope, using different strength indexes and Duncan model parameters obtained by triaxial drainage shear test. The results show that the landslides mechanisms caused by excavation and rainfall infiltration are relaxation failure and soften failure, separately. The deformation zone lies within the 0-4m soil layer and slope toe. The reinforcement measures of resistance piles set at slope toe and combined bolting and shotcrete set at slope surface were presented. After reinforced, the stability of excavated slope increased.

The influence of the photoinjector exit aperture on the wakefield generated by the strongly accelerated electron beam, has been theoretically studied in a companion paper. In this communication we study the effects of such a wakefield on the beam, in that propagation stage where the beam approaches the hole and enters it, i.e. the propagation stage where the influence of the photoinjector exit hole must be taken into account. First, the perturbated wakefield map (E, B)(x, t) is shown for various instants, and for photoinjector and beam parameters corresponding to typical values on ELSA, the CEA-Bruyeres-le Chatel high-current, high-brilliance electron beam facility. Then, the effects on the beam quality are studied in terms of emittances, when the beam approaches the hole. These effects are compared to the corresponding ones, previously obtained for a wakefield map where the exit hole perturbation had been neglected.
A number of variables, such as the temperature of the PV modules, the amount of solar radiation available, and the buildup of dirt on the solar panels, have an impact on the performance of photovoltaic (PV) systems. O...
