    Notes: Banks’ size, liquidity and profitability are the main determinants of their capital ratios in Taiwan. Large banks implicitly substitute bank capital for regulator’s capital and banks mainly depend on internal cash flows for capitalization. However, medium-sized banks in Taiwan use liquidity as a substitute for bank capital, and small banks with low liquidity tend to have lower capital ratios. Regulators should pay close attention to these banks since they may be undercapitalized.

    Notes: We reported the first attempt to describe mucosa-associated bacterial populations in the chicken ceca by molecular analysis of 16S rRNA genes. Bacteria in the mucosa were highly diverse but mainly Gram-positive with low G+C. Fusobacterium prausnitzii and butyrate-producing bacteria comprised the largest groups among 116 cloned sequences. Twenty five percent of the clones had less than 95% homology to database sequences. Many sequences were related to those of uncultured bacteria identified in human feces or the bovine rumen. Terminal restriction fragment length polymorphism (T-RFLP) analysis revealed some differences between bacterial populations present in the mucosa and lumen of ceca. Greater resolution of bacterial population was obtained using a culture-independent approach rather than a culture-based approach.

    Notes: Bacterial populations in the ileum of broiler chickens were analyzed by molecular analysis of 16S rRNA genes and compared to those in the cecum. Bacteria found in the ileal mucosa were mainly Gram-positive with low G+C content. There were 15 molecular species among 51 cloned sequences. More than 70% of the cloned sequences were related to lactobacilli and Enterococcus cecorum. Two sequences had 95% or less homology to existing database sequences. Terminal restriction fragment length polymorphism (T-RFLP) analysis revealed differences among bacterial populations present in the mucosa and lumen of the ileum. Comparative studies by T-RFLP and sequence analyses of 16S rRNA genes indicated a less diverse bacterial population in the ileum (mucosa and lumen) than in the cecum. Lactobacilli, E. cecorum, and butyrate-producing bacteria related (including both identified and unidentified species) sequences were the three major groups detected in ilea and ceca. Although butyrate-producing bacteria may have good potential in the development of novel probiotics for poultry, verifying the presence of the bacteria in the chicken gut is required to warrant further investigation.

    Notes: The normal stress distributed in the mid-bondline of the adhesively bonded joint undercleavage loading was investigated using the elastic finite element method (FEM) and the straingauges method to reveal the real normal stresses distribution in the metal-to-metal joint while theload was increased. The results from the finite element analysis (FEA) showed that there is always apeak stress of the normal stress Sy in the mid-bondline occurred at a point close to the loading pinaxis. When the load was increased from 0.5 kN to 3 kN, there was also a point located at about x =16mm along the length of specimen where there is without any normal stress at all. The result ofstress Sy from the FEA is nearly the same as that one obtained from the strain gauges method. It wasalso found that there was a evidently hardness change in the bonded zone of the adherend made fromstructural steel or pure copper, which can be used to explain the procedure of the joint and discussthe distribution model of the normal stress Sy in the joint under the cleavage loading

    Notes: Under imitating human physiological solution, the fretting behaviors of flat cortical bonespecimen from fresh human femur in the axial orientation against TA2 titanium ball with diameterof 40 mm had been investigated. The coefficients of friction (COF) and fretting logs werecalculated automatically. The worn surfaces of the cortical bone were analyzed by means of laserconfocal scanning microscopy. The results showed that the fretting logs for the cortical bone variedwith the increase of the cycles from the elastic partial slip (D=5 (m), the elastoplastic partial slip(D=15 (m) to gross slip (D=30 (m), respectively. The fretting regime transformed from the partialslip regime directly to the gross slip regime without the mixed fretting regime. And the evolution ofthe COF in each fretting condition was also compared statistically. The fretting damage in theelastic partial slip state was slight. But the abrasive wear and micro-fracture were observed in theplastoelastic partial slip state and gross slip regime. The wear depth increased with cycles and wellrelated to the COF of the cortical bone in each fretting condition. To reduce the fretting damages ofbone, it is advisable to control the displacement amplitude at bone-implant interface

    Notes: The effect of the preformed deflection angle in the lap zone on the failure mode and thestresses distribution in the single-lap joint made of the epoxy adhesive and the aluminium adherendwas investigated using elasto-plastic finite element method (FEM) and the experimental method ofthe shear strength testing. The failed surfaces were studied with the diagrams of scanning electronmicroscopy (SEM). The results from the numerical simulation showed that all the peak stresses inadhesively bonded single lap joint were decreased first and increased again as the preformeddeflection angle was increased from 00 to 150. The lowest values occurred when the angle was takenas 100 and its strength is 22.1% higher than that of the standard one as the peak stresses weredecreased and the stress distributed more evenly. The SEM images also show that the failure modeof the joint was transmitted from the adhesion to the mixed one as the deflection angle increased

    Notes: In the subsurface damage observations on the wear behavior of brittle dental porcelains,it still remains unsolved that how to distinguish the cracks that develops accidentally during thepreparing sample process from those actually produced in the tests. In the sliding friction tests, thebonded-interface technique (BIT) was successfully used for subsurface damage evaluations. Theprofile of wear scar was easily observed on the cemented section of the blocks without inducing anycracks. The stresses on the surface and internal of dental porcelains were calculated with the contactelement method (CEM) by ABAQUS software. The model of rectangular dental porcelain and Si3N4ball were developed based on sliding friction tests. The Si3N4 ball modeled in this study was of thediameter of 4mm and 12 mm. The size of Vita VMK 95 porcelain blocks was 5 mm wide, 2 mmthick and 15 mm long. The glue layer thickness values are 10 .m, 20 .m and 30 .m. The loadingof the Si3N4 ball was modeled as a constant distributed vertical load applied across the bonding lineof the porcelain. Stresses and displacements of all nodes of the model, especially at the bondinginterface, were analyzed and compared. The results of the study indicated that stress valuescorrelated strongly to the applied loads. Stress distribution was symmetric about thebonded-interface plane. The maximum occurred in surface layer and the minimum on the bottomline in the porcelain blocks. Along the interface, stresses decreased with the distance from thesurface of porcelain. On the other hand, high stresses focus on the surface part and go sharply downin the internal region along the depth direction. Among the parameters of sliding test on the stresses,the load effect is prominent. The BIT model experiences a different, non-axisymmetric stress fieldthan that of real work-piece. So the BIT should not be considered as a reliable source of quantitativeanalysis but as a qualitative method for observing the form of the damage modes with more visibleinformation than the conventional tools

    Notes: Pure Ti, TiN and graphite powders were mechanically alloyed to synthesize Ti(C,N) powderwith nanocrystalline microstructure. The effect of milling variables on the synthesizing behavior of thepowders was investigated. As a result of milling, nano Ti(C,N) phase was synthesized by mechanicalalloying. After that, Ti(C,N)-based cermets were fabricated with the powders as raw ceramic materials. Itwas found that the grain size was affected by the content of mechanical alloyed (MAed) Ti(C,N). Thegrains of the cermet with suitable MAed Ti(C,N) powder were smaller than that of the typical cermetsprepared from the commercial powders, and the rim phase surrounding the hard core was also complete.As a result of this, the transverse rupture strength and hardness of the cermets were improved

    Notes: The influence of the fiber/matrix interlayers on the mechanical properties of T800-HB fiber (akind of carbon fiber) (the fibrous is three-dimensional four-directional braided) reinforced silicon carbide(SiC) matrix composites has been evaluated in this paper. The composites were fabricated through PIPprocess, and SiC layers were deposited as fiber/matrix interlayers by the isothermal CVD process.Fiber/matrix debonding and relatively long fiber pullouts were observed on the fracture surfaces. Themechanical properties were investigated using three-point bending test and single-edge notched beamtest. The T800-HB/SiC composites exhibited high mechanical strength, and the flexural strength andfracture toughness were 511.5MPa and 20.8MPa•m1/2, respectively
