Case Histories and Vibratory Characteristics of Vibro-driven Piles

The vibratory characteristics of vibro-driven piles into the ground have not so far been discussed systematically in detail. This paper concerns the results of monitoring vibro-driven piles in various types of ground. In order to assess the monitoring of vibration performance, time-series monitoring data on the reaction force at the pile tip and the vibratory acceleration of the pile top are analyzed in relation with the soil profiles of four monitoring sites. As the result, it has been elucidated that the pile tip reaction force and vibratory acceleration are systematically presented by the dynamic force and the mass weight of the vibrohammer and pile. Furthermore, engineering applications of the vibratory characteristics of vibro-driven piles are presented

Charmonium properties at finite temperature on quenched anisotropic lattices

We study charmonium properties below and above $T_c$ up to 1.8$T_c$, on quenched anisotropic lattices. Information of the spectral functions is extracted using the maximum entropy method and the constrained curve fitting. We also calculate the color singlet and averaged free energies and evaluate the charmonium spectrum with the potential model analysis. The relation between the lattice result of the spectral function analysis and the potential model is discussed.Comment: Lattice2004(non-zero), 3 pages, 4 figure

Swelling of a V-5Fe Alloy After Irradiation in JOYO

Void swelling behavior of a vanadium iron binary alloy has been studied using JOYO as an irradiation facility. The swelling at a damage level of approximately 14dpa was as high as 30% for 600℃ irradiation, which is qualitatively consistent with the large swelling observed after FFTF/MOTA irradiation about 30dpa. The evolution of dislocation microstructure is very fast and the sink strength ratio Q is much greater than unity except for the highest damage level studied, yet the swelling rate is more than 2%/dpa. Several possible mechanisms involving segregation effects have been discussed. It has been suggested that any successful model should be capable of predicting the observed swelling rate more than 2%/dpa under condition of Q value much greater than unity

Prediction of fetal acidemia in placental abruption

BACKGROUND: To determine the major predictive factors for fetal acidemia in placental abruption. METHODS: A retrospective review of pregnancies with placental abruption was performed using a logistic regression model. Fetal acidemia was defined as a pH of less than 7.0 in umbilical artery. The severe abruption score, which was derived from a linear discriminant function, was calculated to determine the probability of fetal acidemia. RESULTS: Fetal acidemia was seen in 43 survivors (43/222, 19%). A logistic regression model showed bradycardia (OR (odds ratio) 50.34, 95% CI 11.07 – 228.93), and late decelerations (OR 15.13, 3.05 – 74.97), but not abnormal ultrasonographic findings were to be associated with the occurrence of fetal acidemia. The severe abruption score was calculated for the occurrence of fetal acidemia, using 6 items including vaginal bleeding, gestational age, abdominal pain, abnormal ultrasonographic finding, late decelerations, and bradycardia. CONCLUSIONS: An abnormal FHR pattern, especially bradycardia is the most significant risk factor in placental abruption predicting fetal acidemia, regardless of the presence of abnormal ultrasonographic findings or gestational age

Artificial colloids versus human albumin for the treatment of ovarian hyperstimulation syndrome: A retrospective cohort study

Background: The optimal colloid solution for the treatment of ovarian hyperstimulation syndrome (OHSS) remains to be established. Objective: We aimed to compare artificial colloids (AC) with human albumin (HA) for the treatment of OHSS. Materials and Methods: In this retrospective cohort study, data for OHSS participants were collected from a national inpatient database in Japan. The participants received intravenous fluid management with AC (n = 156) or HA (n = 127). We compared the two groups in terms of the length of stay, development of post-treatment complications, and termination surgery. Results: In multivariable linear regression analyses for log-transformed length of stay with reference to the OHSS participants receiving AC, the regression coefficient (95% confidence interval) in participants receiving HA was 0.03 (-0.04-0.09, p = 0.42). Thromboembolism occurred in two participants in the HA group and three participants in the AC group. Two participants in the HA group suffered renal failure during hospitalization. No participants underwent termination surgery in the two groups. Conclusions: The present results showed comparable efficacy between AC and HA for the treatment of OHSS. There were no significant differences in post-treatment complications between the two groups. Key words: Ovarian hyperstimulation syndrome, Treatment, Colloid, Length of stay

A Clinical Study Evaluating an Aspiration-type Semi-Automatic Cutting Biopsy Needle (SCIRO-1702)

An aspiration-type semi-automatic cutting biopsy needle enables tissue cutting during application of negative pressure, which is expected to contribute to a larger amount of specimen. The aim of the present study was to evaluate this novel needle in a clinical setting. Patients who underwent image-guided percutaneous biopsy for lung or renal masses were enrolled. Cutting biopsy was performed with and without aspiration during each procedure. The specimens were weighed using an electronic scale. The weights were compared between specimens obtained with and without aspiration using a paired t-test. The data from 45 lung and 30 renal biopsy procedures were analyzed. In lung biopsy, the mean±standard deviation weights of specimens obtained with and without aspiration were 2.20±1.05 mg and 2.24±1.08 mg, respectively. In renal biopsy, the mean weights were 6.52±2.18 mg and 6.42±1.62 mg, respectively. The weights were not significantly different between specimens obtained with and without aspiration either in lung (p=0.799) or renal (p=0.789) biopsies. The application of negative pressure with the aspiration-type semi-automatic cutting biopsy needle did not contribute to an increase in the amount of the specimen obtained in lung and renal biopsies

Scalar Glueball Mass Reduction at Finite Temperature in SU(3) Anisotropic Lattice QCD

We report the first study of the glueball properties at finite temperatures below T_c using SU(3) anisotropic lattice QCD with beta=6.25, the renormalized anisotropy xi \equiv a_s/a_t = 4 and 20^3 \times N_t (N_t=35,36,37,38,40,43,45,50,72) at the quenched level. From the temporal correlation analysis with the smearing method, about 20 % mass reduction is observed for the lowest scalar glueball as m_G(T)=1250 \pm 50MeV for 0.8 T_c < T < T_c in comparison with m_G \simeq 1500 \sim 1700MeV at T \simeq 0.Comment: This is the second revised version using more gauge configurations. 5 pages, Latex2e, 5 figure
