    Notes: In this study, methane gas absorption ability of activated carbon (AC) with surfacefunctional group effect, was evaluated after nitric acid and urea treatment of AC surface. Specificsurface area and pore distribution of AC were studied through nitrogen absorption isotherm at 77 K.Micro pore volume was calculated through H-K method. Absorbed methane amount was evaluatedthrough volumetric method at room temperature by using auto absorption apparatus. Absorbedmethane amount of AC was found to increase with specific surface area increase. Correlationproposed between the methane absorption amount and surface nature indicates that the surfacenature plays an important role on the absorption amount at a given temperature

    Notes: Abstract Autonomously replicating sequence binding factor 1 (ABF1) has been implicated in the control of a variety of gene expressions in Saccharomyces cerevisiae. In this paper evidence is presented that ABF1 is involved in the glucose-dependent expression of the TDH3 gene which encodes glyceraldehyde-3-phosphate dehydrogenase. ABF1 binds to consensus sites located between-420 and-250, and between +77 and +200, and acts as a transactivator in an orientation-independent manner on both upstream and downstream sites. TDH3-lacZ fusions having an ABF1 consensus motif showed glucose-dependent expression of TDH3, whereas in the abf1 mutant strain JCA35 glucose-dependent expression disappeared. These findings suggest that ABF1 functions as a glucose-dependent transactivator for the expression of the TDH3 gene.

    Notes: Diffusion tensor imaging (DTI) provides quantitative information in the magneticresonance imaging on the diffusion anisotropy about the integrity of white matter tracts. The aim ofthis study was to measure diffusion anisotropy and to correlate with upper-limb motor recovery infour chronic hemiparetic patients with thalamic hemorrhage. Fractional anisotropy (FA) wasmeasured in the posterior limb of internal capsules (IC) in the affected side and in the correspondingcontralateral normal side before and after 6 week motor training. The correlation between motorrecovery of the affected hand and the ratio of FAs of the affected side and the contralateral normalside were investigated. Both FA ratio and motor function significantly increased after the training.A significant correlation was found between motor recovery and FA in the posterior limb of IC. Thedegree of impairment in diffusion anisotropy of hemiparetic patients might be helpful in prognosisof the motor function

    Notes: In the construction of composite bridge structures, various types of shear connectors areusually used to provide an efficient load transfer and the composite action of two or more differentmaterials. In the previous work conducted by authors, a new type of the shear connector wasintroduced, which is the perforated shear connector with flange heads (T-shaped perforated shearconnector), and the structural behavior of the shear connector was discussed based on the results ofpush-out tests. For the practical design of new shear connector, it is necessary to develop theequation for the prediction of the load carrying capacity of the shear connector. In this study, theexisting design equations for the Perfobond shear connector were briefly analyzed and the equationfor the prediction of the shear capacity of T-shaped perforated shear connector was suggestedempirically. By comparing the results obtained by the suggested equation, the existing equations forthe Perfobond shear connector, and the experiment, the applicability and effectiveness of thesuggested equation was estimated

    Notes: In this study, we determined joint moments and muscle forces in the lower extremity duringwalking with different heel-height shoes using the 3D motion analysis and the correspondingmusculoskeletal modeling. Totally fifteen healthy women participated in the 3D motion analysis forvarious walking with barefoot, flat shoe, 3cm, 6cm and 9cm high heels. Inverse dynamic simulationswere also performed using a musculoskeletal model in order to calculate joint moments and muscleforces in the lower extremity. As for the hip, joint angles, joint moments and corresponding muscleforces did not show significant differences. Rectus femoris, a biarticular muscle for hip flexor and kneeextensor, revealed stronger effect on the knee than the hip. Soleus, playing the most important role forankle plantarflexor, showed decreases in the maximum muscle force at pre-swing, as heel heightincreased. Tibialis anterior produced larger dorsiflexion moments for foot clearance with higher-heeledshoes

    Notes: This paper presents the results of an investigation on the force transfer mechanism in anembedded column base of a composite structure. In the experimental program, eighteen push-outspecimens were tested. The factors influencing the mechanism of force transfer were the amount ofconfining reinforcement, compressive strength of concrete, and diameter of stud connectors. Theresults of experiment indicated that force transfer could be characterized into two stages, and thefactors governing each stage were identified. The first stage was governed by the bond strengthbetween the steel column base and the concrete. The second stage begun after chemical debondingand was governed by the shear strength of stud connectors as well as the frictional strength betweenthe steel and the concrete. Based on the experimental results, the equations to estimate the bondstrength, the friction strength, and the shear strength of stud connectors were proposed. The loadcarrying capacity of an embedded steel column base could be predicted by taking the sum of theshear strength of stud connectors and the friction strength. The predicted load carrying capacity wasfound to agree well with the experimental results over various range of concrete stress

    Notes: Ba8Al16Si30 type I clathrate was produced by arc melting and thermoelectric propertieswere investigated. The phase transformation behavior of arc-melted type I Ba8Al16Si30 wasexamined by thermogravimetric analysis, differential scanning calorimetry, hardness test, densitymeasurement, X-ray diffraction and scanning electron microscope analyses. Homogenization wascarried out to induce the transformation to a thermoelectric phase at 773K to 973K for 5 hours and24 hours in the vacuum furnace. Thermoelectric properties in the temperature range between 300Kand 600K were measured and evaluated. Electrical conductivity was decreased and Seebeckcoefficient was increased with increasing homogenization temperature and time. The arc-meltedand the homogenized specimens represented n-type conduction at temperatures examined, and theyshowed reliable thermoelectric behaviors with increasing homogenization temperature and time

    Notes: The mechanical property of sintered MoSi2 materials has been investigated, based on thedetailed examination of their microstructures. The nondestructive technique by an ultrasonic wavewas also used for evaluating the damage behaviors of MoSi2 materials suffered from the cyclicthermal shock. MoSi2 materials were sintered at the temperature of 1723 K. The flexural strength ofMoSi2 materials gradually decreased with increasing the thermal shock cycle, accompanying theextensive creation of surface cracks. The increase of thermal shock cycles resulted in a great decreaseof ultrasonic wave velocity and a linear increase of attenuation coefficient for MoSi2 materials

    Notes: Pressure distributions on the buttocks and thighs by the functional electrical stimulation onthe gluteus maximus, sartorius and hamstring in the seating posture were analyzed for ten healthyyoung volunteers in order to determine which muscle can be stimulated for pressure ulcer prevention.Muscles were stimulated every 5 seconds over 30 seconds by the MP150 stimulator. Pressuredistribution and ground reaction forces on the stimulated buttocks and thighs increased when thegluteus maximus was stimulated. Pressure on the stimulated thigh slightly decreasedwhen stimulating sartorius and hamstring individually. With a simultaneous stimulation of thegluteus maximus and sartorius, pressures on the stimulated buttocks and thighs increasedsignificantly, but pressure on the opposite buttock decreased significantly. With a simultaneousstimulation of the sartorius and hamstring, both pressure on the stimulated thigh and the groundreaction force significantly decreased

    Notes: The purpose of this study is to quantitatively evaluate foot motions in the normal and halluxvalgus(HV) patients using a proposed multi-segment foot model. Results showed that HV patientsexhibited relatively smaller flexion/extension, especially in terminal stance. An early abduction at theankle during terminal stance was also noted in HV patients, which resulted in an excessive abductionin subtalar joint. In HV patients, medial MP joints exhibited excessive amount of adduction duringterminal stance. In HV patients, hallux MP joint and talocrural joint exhibited excessive externalrotation over the whole period of gait cycle. Understanding the detailed foot motions by the presentmulti-segment foot model would be very useful to diagnose and to treat patients with various footdiseases
