Our previous paper [Phys. Rev. B 36, 1754 (1987)], in which Hosemann's paracrystal theory was extended to three-dimensional cubic systems, contained some errors. In this paper, we have corrected these errors and further refined the theory. The scattering profiles by our new are not so different from ones; satisfactory, even better agreements with experimental data also obtained slightly larger distortion factor g.
The three-dimensional paracrystalline lattice factors Z(q)'s for a face-centered-cubic and body-centered-cubic lattice, in addition to simple-cubic were calculated. thus calculated could reproduce the diffraction peaks at characteristic positions each cubic system over fairly wide range of g values (g is degree distortion). In distortion, thermal oscillation crystal size effects also considered. numerically profiles compared with light small-angle neutron scattering curves polymer latex...

Abstract Implant surgery with surgical guide has been introduced a concept of position improvement. The might be considered as easy even for inexperienced clinician because step simplicity. However, there are residual risks, resulting in postoperative complications. aim this study was to assess the accuracy implant by clinicians vitro. After preoperative computed tomographies (CTs) five artificial models unilateral free‐end edentulism scan templates, guides were established from templates....
Microstructures and hydrogen storage properties of Mg-Al super laminate composite alloys were investigated. The laminated sample was made by alternately stacking Mg films Al films. subjected to repetition cold-rolling under an ambient condition (super lamination technique), combined with final heat treatment argon gas atmosphere. number thickness nearly 15000 layers about 50μm, respectivery. Their microstructures studied scanning electron microscopy, X-ray diffractometry volumetric method...
Some hydrogen storage materials with the hexagonal CaCu5-type crystal structure have two pressure plateaux during absorption and desorption processes. To clarify correlation of hydrogenation properties between plateaux, we investigated pressure-composition isotherms several binary RNi5 (R = La, Ce, Pr, Nd Sm) intermetallic compounds at pressures up to 35 MPa temperatures ranging from 196 423 K by use a modified Sieverts' method. We also determined unit cell volume correlate structure. It was...

In order to improve the hydrogenation property of Mg/Ti laminate composite, Ni was added as a third element. Hydrogen storage properties laminated Mg/Ti/Ni alloy films were studied. Laminated multilayer prepared by cold rolling stacked Mg, Ti and under ambient conditions. The foils subjected repetition stacking, resulting in super-laminated with thickness less than 0.3mm, containing more 15000 layers. Microstructures super-laminates studied scanning electron microscopy X-ray diffractometry....
This paper is a brief description of the small scale field demonstration we presented at ITS World Congress 2013 in Tokyo. We showed that during disasters vehicles can act as information hubs conveying human or machine centric from an area where telecommunications network disrupted, to infrastructure available. The was combination different means communication technologies including Wi-Fi, TV white space, cellular networks, and movement themselves. Use space for inter-vehicle communications...
We systematically investigated the hydrogenation and dehydrogenation properties for heavy rare earth-based binary RHNi5 (RH = Gd, Tb Dy) intermetallic compounds evaluated correlations between crystallographic thermodynamic properties. XRD analysis shows that all crystallize in hexagonal CaCu5-type crystal structure. In analogy to light RLNi5 (RL La, Pr, Nd Sm) both lattice constants of decrease with increasing atomic number RH element due lanthanide contraction. On pressure-composition (P-C)...
Vehicle Safety Communications (VSC) have been proposed as part of ITS development to reduce the traffic accidents by providing critical road information beyond driver's view. The system is planned be implemented on 700MHz band in Japan, and 5.9GHz Europe America. Some applications require communication Non-line-of-Sight (NLOS) conditions. However, feasibility study performance NLOS conditions still an open issue, especially urban environment with flow. In this paper, we explain differences...
Abstract Background A novel type of implant (Straumann® BLX implant) has been developed for certain stability from the mechanical and biological aspects is expected placement in atrophic maxilla with sinus floor elevation (SFE). Purpose The aim this study was to evaluate primary implants different macrodesigns an SFE simulated model. Primary stabilities defined as maximum insertion torque (MIT) quotient (ISQ) were compared between other types. Materials Methods Five types Straumann® 10 mm...
In this study, effects of reinforcing on the damage reinforced concrete slabs subjected to Explosive loading has been experimentally investigated improve design and estimate methods structures. Pentolite were detonated surfaces seven kinds labs, with different reinforcement. After tests, in was observed detail analyzed for crater, spall, breach crack. The tests results showed that using steel net or high ratio bars are slightly effective prevent crater spall depth, but aren't perfectly, so on.
