The vibration generated by the machinery on board is transmitted to the hull and into the water. At the early design stage, the prediction of the hull vibration and the radiated noise level is very important to reduce their levels. In this study, SAE(Statistical Energy Analysis) technique is applied to predict structureborne noise level of the hull considering fluid loading. Rayleigh integral is applied to predict the radiated noise level. The results of comparision between the predictions and measurements for the reinforced cylindrical shell have shown good agreements.

Studies were carried out to compare the bioconcentrations of TCDD and PCB 126 in different sizes of Japanese medaka, and to examine the whole body elimination kinetics of TCDD and PCB 126 in juvenile Japanese medaka. For bioconcentration studies, different sizes of fry and juvenile medaka were exposed statically to varying doses of waterborne TCDD and PCB 126 for 96 hours. (omitted)

Polyurethane are used for a wide range of commercial applications such as adhesives or coatings for various substrates including textile fabric, plastic, wood, glass fiber, and metals. The types of polyurethane ionomers have been reported according to the ionic charges on the polymer main chain, i.e. anionomer, cationomer, and zwitterconomers. (omitted)

Waterborne polyurethane dispersion (PUD) was synthesized by capping the NCO groups of polyurethane prepolymers, prepared from isophorone diisocyanate, polycarbonate diol and dimethylol propionic acid, with aminopropyl triethoxysilane (APS). Subsequently, silylated acrylic polyurethane dispersion was synthesized by reacting the PUD with the mixture of acrylate monomers, 2-hydroxyethyl methacrylate and methyl methacrylate. The average particle size of silylated acrylic polyurethane dispersion, measured by the dynamic light scattering method, was increased from 39.0 nm to 399.8 nm by increasing the addition amounts of APS. Also, the pencil hardness of coating films of silylated acrylic polyurethane dispersion was enhanced from B grade to F grade with increasing APS content.
