Shape oscillation of bubbles in a row excited by ultrasonic vibration

Behaviors of bubble(s) exposed to an ultrasonic vibration are focused. Size of the bubbles interested in the present study is of O(1 mm) in diameter. The bubbles were injected through the micro syringe to the test fluid (water or water/surfactant mixture) filled in the rectangular tank. Ultrasonic vibration was irradiated to the bubble(s) after the detachment of the bubble from the tip of the syringe; thus the bubbles were exposed to the periodic oscillation in rising the test fluid. The authors clearly detect radial and shape oscillations under the large-amplitude vibration by use of high-speed camera. Preferable mode number of the shape oscillation, and the transition process from the radial to the shape oscillation are discussed.

Decomposition of nitric oxide on metallosilicates under a large excess oxygen condition with coexistence of a low concentration cetane

Catalytic removal of NO was conducted under the condition of large excess O₂ by using different kinds of metallosilicates having MFI structure. With coexistence of a low concentration of cetane, H-Fe-silicate, which had both acidity and redox property, exhibited the maximum performance among the catalysts tested at a fairly lower temperature range, around 350 °C, and the NO was totally converted. The temperature dependence of NO conversion was consistently similar to that of cetane combustion.     

Renin-angiotensin system in an infant with malignant renovascular hypertension

The clinical and electromyographic signs of the misdirection syndrome after oculomotor palsy are described. Besides the previously described findings we found an increase of intraocular pressure dependent on the direction of gaze. In three young patients (16-26 years), we were able to demonstrate an aberrant reinnervation of the ciliary muscle, which was responsible for an increasing myopia in adduction. These observations supplement the previous concept of the misdirection syndrome.     

Non-grafting method of vaginal construction for patients of vaginal agenesis without functioning uterus (Mayer-Rokitansky-Küster syndrome)

The effect of acute hypoxia on the changes of plasma cortisol level and hippocampus NE level of cat during inhalation of 21%, 10.4% or 7.9% O2 were investigated. It was found that both 10.4% and 7.9% O2 inhalation caused a gradual increase in plasma cortisol level reaching a plateau in 30-45 min time. While the contents of NE in VHIP and DHIP showed significant decrease 30 min after hypoxia. The degree of both these changes are not related to the hypoxic level of the inhaled O2. The results show that acute hypoxic stress would induce some increase in plasma cortisol level and some decrease in hippocampus NE content.     

Three-dimensionally slanted illusory contours capture stereopsis

In stereo capture a stereogram of a crossed illusory figure pulls a texture bounded by the illusory contours to the same depth plane with the illusory figure. We investigated whether three-dimensionally curved and slanted illusory figures could capture a repeating background texture. According to results, stereoscopic capture was perceived when a disparate illusory contour was slanted provided that the period of the background texture was consistent with the three-dimensional geometry of the illusory surface. We suggest that stereo capture is actually induced by disparate rows of points defined by vertical cut-out sectors and the induced disparity spread is constrained by illusory contours and possible discrete matches of the background texture.     

Induction of CYP2A5 by pyrazole and its derivatives in mouse primary hepatocytes

OBJECTIVE: To assess the effect of ramipril on indicators of glucose metabolism, incl. insulin resistance, on renal function with microalbuminuria, changes of some echocardiographic signs of hypertrophy and compliance of the left ventricle in patients with hypertension and type II diabetes mellitus. MATERIAL AND METHODS: The authors examined 32 patients with hypertension grade I and II and with diabetes type II, who had ramipril, 2.5-10 mg/day, for a period of six months. The examination before and after long-term treatment comprised basic biochemical sampling incl. concentrations of immunoreactive insulin, C-peptide and glycated haemoglobin and also complete functional examination of the kidneys, incl. microalbuminuria. Echocardiographic examination was focused on assessment of signs of hypertrophy and compliance of the left ventricle. Treatment of diabetes was not changed in the course of 6 months. RESULTS: In addition to the anticipated drop of blood pressure a declining trend of insulin resistance was recorded, there was a significant decline of microalbuminuria and a rise of natriuresis, the left ventricle mass declined and its compliance improved. CONCLUSION: Ramipril one of the inhibitors of angiotensin converting enzyme is an effective and useful medication for type II diabetics suffering from hypertension.

Essentially exact ground-state calculations by superpositions of nonorthogonal Slater determinants

An essentially exact ground-state calculation algorithm for few-electron systems based on superposition of nonorthogonal Slater determinants (SDs) is described, and its convergence properties to ground states are examined. A linear combination of SDs is adopted as many-electron wave functions, and all one-electron wave functions are updated by employing linearly independent multiple correction vectors on the basis of the variational principle. The improvement of the convergence performance to the ground state given by the multi-direction search is shown through comparisons with the conventional steepest descent method. The accuracy and applicability of the proposed scheme are also demonstrated by calculations of the potential energy curves of few-electron molecular systems, compared with the conventional quantum chemistry calculation techniques.
