作者： Dongfeng HE mitsuharu shiwa Satoshi TAKAYA Naoto TSUTSUMI Koichi TSUCHIYA National Institute for Materials Science

We developed electromagnetic methods to evaluate the steel reinforcing bar in concrete. Using two probes and lower excitation frequencies of 3.8 k Hz and 4.2 k Hz, the depth and the diameter of the steel reinforcing bar can be evaluated and the resolution of better than 1 mm is obtained. Using higher excitation frequency of about 80 kHz, the corrosion of the steel reinforcing bar can be evaluated.

An experimental and analytical study has been carried out to obtain the clear understanding of a shock wave transition associated with a steady two-dimensional overexpanded flow. Two-dimensional inviscid theory with respect to a shock wave reflection is used in the present study on the characteristic of shock waves. The results obtained from the flow analysis are compared with those obtained from flow visualizations. It is shown that in the region of regular reflection, the angle of an incident shock wave becomes lower than that calculated by two shock theory with an increment in the ratio PJPb of the nozzle exit pressure Pc to the back pressure Pb. It is indicated that the configuration of shock waves in overexpanded jets is influenced by the divergent angle at the nozzle exit. Also it is shown from the flow visualization that a series of shock waves move into the nozzle inside with a decrease in pressure ratio Pc/Pb, even if the Pc/Pb is under overexpanded conditions.

In this paper, the characteristics of a pressure wave propagating against two parallel subsonic streams in a constant-area straight duct are investigated by one-dimensional analysis, two-dimensional numerical simulation, and experiments. Computations have been carried out by the two-dimensional Euler Equations using the Chakravarthy-Osher-type TVD scheme. Optical observations by the schlieren method as well as wall pressure measurements have been performed to clarify both the structure and the propagation velocity of pressure waves. The results show that the pressure wave propagating against the streams changes into a bifurcated pressure wave and the bifurcation occurs in the low speed streams. It is also found that the propagation velocity of the pressure wave obtained by the analysis and computation agrees well with the present experimental data.

AIM- To examine histology- and tumor-location specific risk factors of gastric cancer （GC）.METHODS： This was subjects were 216 GC the period 2000-2002 non-cancer patients hospital. We obtained habits, and others by a a case-control study. The study patients newly diagnosed during and 431 controls selected from matching in age, gender, and information on lifestyles, dietary ***： The subjects who were not eldest among his/her siblings were at a slightly elevated GC risk （OR 1.3; 95% CI 0.8-2.0）. Salting meals before tasting was related to an increased GC risk （OR 3.5; 95% CI 1.6- 7.3）. Frequent consumptions of fruits （OR 0.3; 95% CI 0.1-1.0） and vegetables （OR 0.3; 95% CI 0.1-1.0） were related to decreased GC risks. On the other hand, frying foods （OR 1.9; 95% CI 1.0-3.6） and cooking with coal （OR 1.8; 95% CI 1.3-2.6） were related to increased GC risks. Neither Lauren＇s histological classification （intestinal and diffuse types） nor tumor location significantly affected those associations except birth order. The subjects who were not eldest among his/her siblings had an increased risk of GCs in the distal and middle thirds, and their ORs were 1.7 （95% CI 1.0-2.8） and 1.9 （95% CI 0.8-4.3）, respectively. The corresponding OR in the upper third stomach was 0.3 （95% CI 0.1-0.9）. The differences of those three ORs were statistically significant （P = 0.010）.CONCLUSION： The present study shows that birth order, salt intake, consumption of fruits and vegetables, the type of cooking, and cigarette smoking are related to GC risk. In histology and tumor-location specific analyses, non-eldest person among their siblings is related to an increased GC risk in the distal and middle thirds of the stomach, and is related to a decreased GC risk in the cardia.

The acoustic properties of supersonic jet noise from a convergent-divergent nozzle with a baffle have been studied experimentally over the range of nozzle pressure ratios from 2.0 to 8.0. Acoustic measurements were conducted in a carefully designed anechoic room providing a free-field environment. A new approach for screech noise suppression by a cross-wire is proposed. Schlieren photographs were taken to visualize the shock wave patterns in the supersonic jet with and without the cross-wire. The effects of the baffle and the cross-wire on acoustic properties are discussed. It is shown that the baffle has little effect on the screech frequency for the underexpanded supersonic jet without the cross-wire. Also, the cross-wire introduced in supersonic jets is found to lead to a significant reduction in overall sound pressure level.

The purpose of this study was to elucidate the relationship between percentage of body lipid and individual vitamin B6 contents in the anchovy used for production of Japanese soup stock. The contents of individual vitamin B6 compound in foods should be determined to estimate the functionality of foods. Anchovies （Engraulisjaponica） for use as production of iriko, which is a raw material for preparation of Japanese soup stock, were caught using a medium-sized purse seine on May 26th, June 1st, and July 6th 2011 in Tachibana Bay, Nagasaki, Japan. Vitamin B6 contents were analyzed by 4-pyridoxolacone-coversion （all-enzymatic） HPLC. The relationship between body length, lipid content and the individual contents of vitamin B6 compounds in the anchovies was determined. The propriety of anchovies for iriko preparation could not be estimated based on the appearance of length of fishes. The anchovies were rich in vitamin B6, especially pyridoxamine 5＇-phosphate, which may prevent diabetic complications. The percentage of body lipid significantly showed a negative correlation with the content of pyridoxamine 5＇-phosphate. The contents of the other vitamin B6 compounds did not show the significant correlation with the percentage of body lipid.

To assess the role of ultrasonography of submandibular glands (SGs) in the diagnosis of type 1 autoimmune pancreatitis (AIP).METHODSThirty-seven patients who were definitively diagnosed with type 1 AIP according to the international consensus diagnostic criteria (ICDC) for AIP at our institution between December 1990 and April 2016 were retrospectively reviewed. Findings by physical examination, ultrasonography, and scintigraphy of SGs were analyzed to reach a diagnosis based on the ICDC for AIP. The efficacy of corticosteroid treatment in the resolution of hypoechoic lesions in SGs was also evaluated by assessment with ultrasonography before and after treatment in 18 *** sensitivity of multiple hypoechoic lesions in SGs by ultrasonography for the diagnosis of sialadenitis in type 1 AIP (84%) was higher than that of physical examination (46%), scintigraphy (28%), and SGs thickness (49%). Ultrasonographic evidence of hypoechoic lesions in SGs improved the definitive diagnosis of sialadenitis and type 1 AIP by the ICDC criteria in 11 (30%) and 2 (5.4%) cases, respectively. Multiple hypoechoic lesions in SGs were resolved or disappear by corticosteroid administration in 14 of 16 cases with hypoechoic lesions in SGs, whereas the ultrasonographic findings in the remaining 2 cases with hypoechoic lesions in SGs and the 2 cases with homogenous SG parenchyma remained unchanged after corticosteroid *** ultrasonography to detect multiple hypoechoic lesions might be useful for type 1 AIP diagnosis by improving diagnostic accuracy together with the ICDC sialadenitis criteria.
