Preosteoblast Cell Adhesion and Proliferation on Polycaprolactone (PCL) 3D Scaffolds with Hyaluronic Acid Nano Layer

Polycaprolactone (PCL) scaffolds have been widely used for bone tissue engineering. However, PCL is not good due to the lack of cell recognition sites and hydrophobic surface. Hyaluronic acid (HA) is a glycosaminoglycan that plays an important role in adhesion, migration and proliferation. The object of this study is to fabricate the polymeric thin film in order to improving the preosteoblast cells adhesion and proliferation on HA immobilized PCL scaffolds using amine plasma polymerization. HA immobilized PCL scaffold showed no significant effect on preosteoblast cell attachment and proliferation.

Backshore erosion due to high swell waves

High swell has been known for the one of the main causes of beach erosion in the east coast of Korea. In this study, coastal topography changes due to high swells are simulated to find its effect on the backshore by using movable bed experiments and numerical experiments. Sea bottom topographical changes due to various incident waves were investigated using CSHORE model in the numerical experiments. Furthermore, the mechanism and the phenomena of beach erosion due to waves and high swells on the foreshore and backshore were analyzed and compared with movable bed hydraulic experiments

Improving the coastal hazard management in Indonesia: Lesson learned from other countries

The management of coastal development in hazard areas has now become a serious issue due to\ud increasing trend for people to live at the coast, including Indonesia. Unfortunately, coastal hazards often go unaddressed\ud until they happened and brought severe damage the coastal areas. The objectives of this study are to assess and review\ud the quality of the coastal hazard mitigation and management plans that have been implemented in several countries.\ud Therefore, the development of appropriate advance setbacks based on the need to avoid or reduce risk and acceptance of\ud the uncertainties can be established and translated into planning system and management actions in a pragmatic and\ud effective way. Also to be able to transfer the knowledges, technologies and expertise also to be able to share of research\ud findings, lessons learned and best practices to enhance the capability of arranging an optimal coastal hazard\ud management. Such successful experience and knowledge about hazard mitigation action should be shared by taking\ud consideration of local conditions in Indonesia. Also, the preparations for community, such as education and awareness\ud when planning for coastal protection and development, are really important to be considered carefully

Optical Evidence of Multiphase Coexistence in Single Crystalline (La,Pr,Ca)MnO3

We investigated temperature (T)- and magnetic field-dependent optical conductivity spectra (\s\w) of a La_5/8-yPr_yCa_3/8MnO_3 (y~0.35) single crystal, showing intriguing phase coexistence at low T. At T_C < T < T_CO, a dominant charge-ordered phase produces a large optical gap energy of ~0.4 eV. At T < T_C, at least two absorption bands newly emerge below 0.4 eV. Analyses of (\s\w) indicate that the new bands should be attributed to a ferromagnetic metallic and a charge-disordered phase that coexist with the charge-ordered phase. This optical study clearly shows that La_5/8-yPrCa_3/8MnO_3 (y~0.35) is composed of multiphases that might have different lattice strains.Comment: A single file with 9 figures embedded, to appear in Phys.

Orthogonal polynomials in two variables and second-order partial differential equations

AbstractWe study the second-order partial differential equations L[u] = Auxx +22Buxy + Cuyy + Dux + Euy = λnu, which have orthogonal polynomials in two variables as solutions. By using formal functional calculus on moment functionals, we first give new simpler proofs and improvements of the results by Krall and Sheffer and Littlejohn. We then give a two-variable version of Al-Salam and Chihara's characterization of classical orthogonal polynomials in one variable. We also study in detail the case when L[·] belongs to the basic class, that is, Ay = Cx = 0. In particular, we characterize all such differential equations which have a product of two classical orthogonal polynomials in one variable as solutions

Dimensional Crossover driven by Magnetic Ordering in Optical Conductivity of Pr_{1/2}Sr_{1/2}MnO_3

We investigated optical properties of Pr_{0.5}Sr_{0.5}MnO_3, which has the A-type antiferromagnetic ordering at a low temperature. We found that T- dependence of spectral weight transfer shows a clear correlation with the magnetic phase transition. In comparison with the optical conductivity results of Nd_{0.5}Sr_{0.5}MnO_3, which has the CE-type antiferromagnetic charge ordering, we showed that optical properties of Pr_{0.5}Sr_{0.5}MnO_3 near the Neel temperature could be explained by a crossover from 3D to 2D metals. Details of spectral weight changes are consistent with the polaron picture.Comment: 11 pages, 4 figures, submitted to PRL at June

POST-IRRADIATION ANALYSES OF U-MO DISPERSION FUEL RODS OF KOMO TESTS AT HANARO

Since 2001, a series of five irradiation test campaigns for atomized U-Mo dispersion fuel rods, KOMO-1, -2, -3, -4, and -5, has been conducted at HANARO (Korea) in order to develop high performance low enriched uranium dispersion fuel for research reactors. The KOMO irradiation tests provided valuable information on the irradiation behavior of U-Mo fuel that results from the distinct fuel design and irradiation conditions of the rod fuel for HANARO. Full size U-Mo dispersion fuel rods of 4–5 g-U/cm3 were irradiated at a maximum linear power of approximately 105 kW/m up to 85% of the initial U-235 depletion burnup without breakaway swelling or fuel cladding failure. Electron probe microanalyses of the irradiated samples showed localized distribution of the silicon that was added in the matrix during fuel fabrication and confirmed its beneficial effect on interaction layer growth during irradiation. The modifications of U-Mo fuel particles by the addition of a ternary alloying element (Ti or Zr), additional protective coatings (silicide or nitride), and the use of larger fuel particles resulted in significantly reduced interaction layers between fuel particles and Al
