The experiment was carried out in homogeneous propane-air mixture and in several concentration gradient of mixture. Igniter is put on the upper side of the combustion chamber In concentration gradient experiment, fixture was ignited from lean side. An experimental study was conducted in a combustion chamber. The combustion chamber has glass windows for optical measurements at any side. For the measurement of distribution of fuel concentration, infrared absorption method using 3.39μm He-Ne laser was used, and for the observation of propagating flame, Schlieren method was employed. As a measurement result of flame propagation velocity and flammable limit, for a mixture of an identical local equivalence ratio, flame propagation velocity in concentration gradient is faster than that in homogeneous mixture, and rich flammable limit in concentration gradient shows a tendency to be higher than that in homogeneous mixture.

Amyotrophic lateral sclerosis(ALS)is characterized by adult-onset progressive degeneration of upper and lower motor *** numbers of genes are found to be associated with ALS;among those,the first identified gene,SOD1 coding a Cu/Zn-superoxide dismutase protein(SOD1),has been regarded as the gold standard in the research on a pathomechanism of *** accumulation of misfolded SOD1 in affected spinal motor neurons has been established as a pathological hallmark of ALS caused by mutations in SOD1(SOD1-ALS).Nonetheless,the involvement of wild-type SOD1 remains quite controversial in the pathology of ALS with no SOD1 mutations(non-SOD1 ALS),which occupies more than 90%of total ALS *** vitro studies have revealed post-translationally controlled misfolding and aggregation of wild-type as well as of mutant SOD1 proteins;therefore,SOD1 proteins could be a therapeutic target not only in SOD1-ALS but also in more prevailing cases,non-SOD1 *** order to search for evidence on misfolding and aggregation of wild-type SOD1 in vivo,we reviewed pathological studies using mouse models and patients and then summarized arguments for and against possible involvement of wild-type SOD1 in non-SOD1 ALS as well as in SOD1-ALS.

A new triterpenoid saponin, named segetoside k, has been isolated from the seeds of Vaccaria segetalis. On the basis of chemical reaction and spectral analysis, the structure of segetoside K was established as:olean-12-ene-23a, 286-dioic acid 36, 16a-dihydroxy-28-O- [βD-glucopyranosyl-(1 →3)]-β-D-glucopyra-nosyl-(l →2)-β-D-glucopyranosyl-(l→6)-β-D- glucopyranoside(1).

Zirconia （yttria）-alumina ceramic nanocomposites were fabricated from different powders by spark plasma sintering （SPS）. One powder was a commercially available nanocomposite powder TZP-3Y2OA, consisting of 3 mol% yttria-stabilized zirconia （3-YSZ） reinforced with 20wt% alumina, and the other, used as a comparison, was a conventional mechanically mixed powder 3YSZ-2OA, a blend made of 3 mol% yttria-stabilized zirconia powder ZrO2 （3Y） and 20 wt% ,x-alumina powder. The effect of the sintering temperature on the densification, the sintering behavior, the mechanical properties and the microstructure of the composites was investigated. The results showed that the density increased with increasing sintering temperature, and thus, the mechanical properties were strengthened because of the increased densification. The nanocomposite powder TZP-3Y20A was easily sintered, and good mechanical properties were achieved as compared with the powder from the conventional mechanically mixed method, the maximum flexural strength and fracture toughness of which were 967 MPa and 5.27 MPa m 1/2, respectively.

A novel large thiophene-fused polycyclic aromatics 1 based on pyrene 5 has been synthesized, and its structure was confirmed by ^1H NMR, ^13C NMR, MS, UV-vis and elemental analysis. The key steps of the synthesis involved the Stille cross-coupling reaction and followed by selective β-β oxidative cyclization of pendant thienyl rings by FeCl3 under mild conditions.

The conventional electroehromie (EC) phenomena have several drawbacks, for example, a slow response or a short life of color changes because of chemical redox reactions. We have proposed a new mechanism of color changes that are induced by electric fields without redox reactions due to the change of distribution of electrons in the molecules. The purposes of this work are to prepare accumulation LB films of a phthalocyanine derivative and to investigate the possibility of EC properties of the films.

Shi et al. reported the C-O-CSH monolayer self-assembled on Au(111) / mica substrates and the hexagonal arrangement of the molecules. We have studied the possibility of room temperature superconductivity and nano-scale conductive system by the self-assembly monolayer of the C derivative which is C-O-CSH, (C-SAM). We expect that the C-SAM / Au becomes novel conducting materials system if the Au films as substrates are ultrathin. As well known theoretical discussions of room temperature superconductivity had been already done by Little and Ginzburg in one-dimensional (1D) and

Organic soft actuators are of special interest in many fields including intravascular neurosurgery. Ion conductive polymer film (ICPF) actuators have been one of the strong candidates. The ICPF investigated here was a cation-exchange membrane (Nafion117?, Du Pont). When a voltage is given between the metal electrodes of an ICPF actuator, the ICPF actuator bends in the water due to the motion of Li+ cations with associated water. In order to increase the freedom of the deformation of the ICPF actuator, structures of independent electrode pairs were proposed. The electrodes were selectively deposited by non-electrolyzed plating including the Pt [(NH3)6]4+ deposition process in a [Pt(NH3)6]Cl4 solution and the reduction process in a NaBH4 solution. Here, an elastomer adhesive tape with a fine electrode patterns was used as a mask. The actuators processing conditions and their actuator performances were reported in detail.
