We compare two angular regimes for the measurement of changes in the real refractive index of bulk fluid analytes. The measurements are based on the use of the Kretschmann-Raether configuration to sense a change in reflectivity with index. Specifically, we numerically simulate the relative sensitivities of the total i…

In order to investigate the structural relationship between inorganic phase and collagen fibrils in the calcified tissues of lower vertebrates we have carried out a wide and small angle X-ray diffraction investigation on carp scales and bone samples. The small angle patterns from decalcified bone and scales, as well a…
By reacting [Re(CO)3(Hpz)2(pz)] (Hpz = pyrazole) with [Mn(CO)5Br] in toluene in the presence of Et3N, the dinuclear complex [(CO)3Re(pz)3Mn(CO)3](Et3NH) (1) was obtained. The reaction of 1 with molecular oxygen affords the tetranuclear compound [(CO)3Re(pz)3Mn(O)3Mn(pz)3Re(CO)3](Et3NH)2 (3) or the trinuclear compound…
Perigraft fluid from Staphylococcus epidermidis infected grafts in a mouse model significantly inhibits fibroblast proliferation (60-98% at 7 and 28 days), compared with perigraft fluid from sterile grafts. The fibroblast inhibitor was trypsin-heat resistant and dependent primarily upon the bacteria, not the host proi…
A variety of long alkyl acetylenic compounds was synthesized and polymerized by using Rh(I) catalysts. Particularly, the monomer having a terminal hydroxyl group was converted into the high molecular weight of polymer in good conversion, which was soluble in THF, DMSO, and DMF. The high stereoregularity (cis) in the m…
Molybdenum disulfide single crystal (0002) plane XPS spectra are presented. The specimen is a natural mineral of graphite-like layered structure. The sample was in situ peeled in the analysis chamber. The spectra include a survey scan, core level Mo 3d5/2, 3d3/2, S 2s, 2p3/2, 2p1/2, 3s, and valence band. The spectra w…
The condition of brain of brain activity resulting from pressure exerted on the abdomen by waist belts was evaluated by Electroencephalogram (EEG) measurement. We investigated the possibility of estimating psychological and physiological stress arising from waist belts in clothing based on EEG measurements. Waist belt…
Foam extrusion experiments were performed to study the effects of surrounding temperature variation on cell structure and foam density. Linear low density polyethylene and low density polyethylene were used with an endothermic chemical blowing agent in a single screw extruder with a capillary die to form foam rod samp…
The paper reports findings of electric field distribution in power cables with voids entrained in the insulation. The shapes of voids studied are cylindrical and spherical types. Samples studied are oil-impregnated paper-insulated cables and polymer-insulated cables of single-core. The model selected for study is a si…
The presented work describes a molecular approach to the design and synthesis of polyimides with novel structures and properties. Effort has been focused on the chemistry and application of new AB-type amino anhydride monomer, AX-type amino-imide monomer and unsymmetric dianhydride. It has been demonstrated that an AB…
We report on the dielectric response of supercooled organic liquids. Main and secondary relaxation process are described by a quantitative line shape analysis. The results are compared with those obtained for supercooled plastically crystalline phases. Both types of glass forming systems exhibit very similar dynamic s…
The behavior in competitive adsorption-desorption reactions of Cu and Zn was studied in four calcareous soils. Cu and Zn were added to the soil by Cu, Zn, and Cu+Zn sulfate solutions in a CaSO4 background. Soil sorption of these cations was described by equilibrium isotherms that fitted either Freundlich- or Langmuir…
An analysis is made of the diffraction reflection of light in a cholesteric liquid crystal in the presence of magnetooptic activity which leads to wave irreversibility and in particular to nonidentical forward and return wavelengths. It is shown that in this particular case, the Bragg formula containing a single wavel…
The motions of top and bottom dross in a continuous hot dip plating bath were investigated using a transparent cold model vessel with a reduced scale of one-tenth. The flow field in the model bath was classified into three regions as usual; the entry region, the exit region, and the region enclosed with a belt. This b…
New fibers are categorized as: (1) high-performance fiber, (2) high-function fiber, and (3) high-touch fiber. Products appearing in the Japanese market are introduced with the technical background. High-performance fiber denotes fiber that possesses higher mechanical strength, better heat resistance, better acid/alkal…

To see the bundle effects on the electronic and the vibrational properties of single-wall carbon nanotubes (SWNTs), we have measured the resonance Raman scattering of isolated SWNTs and thick bundles. For the measurements of the isolated SWNTs, we used an evacuated sample after bromine doping. A broad and asymmetric t…
This research paper was developed aiming at evaluating the feasibility of using Eucalyptus maculata, E. grandis and E. tereticornis woods, derived from saw mill processing residues to particleboard manufacture. Was manufactured 24 boards, being eight treatments, defined in function of three species and its mixture, an…
