While soybean glycinin was heated in standard buffer containing reducing agent at oil bath and at autoclave, respectively, precipitate occurred. There was the tendency that the precipitate consisted of basic subunit, and its supernatant did acidic subunit. The best separation of each subunit was found under conditions as follows: protein concentration, 0.5% ; reducing agent, 0.5M sodium sulfite; pH 8.0; temperature, 120℃ ; heating period, 10 to 20 minutes; atomospher pressure 2. Okg/cm^2. Simple separation method under such conditions makes it possible to investigate food functional properties of soybean glycinin subunits.

Emulsifying properties of acidic and basic subunits, isolated individually constituting soybean glycinin were studied. Emulsifying stability of acidic subunit was measured by using of a turbidimetric method. The dependence on protein concentration and pH indicated that acidic subunit had much more emulsifying stability than native glycinin and did similar to standard proteins, casein and bovine serum albumin. Basic subunit had much more fat binding capacity than casein and bovine serum albumin. This result suggests that it is more effective to utilize subunit constituting the protein than whole protein as functional food materials.

The intercalation behavior of various saturated aliphatic mono- and dicarboxylate ions ([chemical formula], [chemical formula]) into Mg-Al and Zn-Al layered double hydroxides (LDHs) by the reconstruction method using each oxide solid solution precursors was investigated at 25℃. The oxide precursors prepared by the thermal decomposition of synthetic LDHs were found to intercalate easily these carboxylate ions with reconstructing the LDH layer structure. The interlayer distance and degree of crystallinity of the LDH products diversely varied with the intercalated amount as well as the number of carboxyl group and carbon chain length of the guest anions. The intercalation isotherms of these carboxylate ions were obtained and the Freundlich isotherm equation was applicable in all cases. Furthermore, the effect of the solution pH on the intercalation was found first to be quite large and the intercalated amounts of these carboxylate ions were remarkably decreased with increasing the solution pH. The mechanism for this phenomenon was discussed in detail.

This paper shows that the CADMAS-SURF is effective to compute run-up height of a wave. The result of simulation is good agreement with an empirical equation by Hunt. Using the CADMAS-SURF method, we carried out the maximum run-up height at stairs type gentle slope and uniform slope. On the gentle slope type seawall, the maximum run-up height of wave was half of uniform slope its.

Artificial reefs have been used to protect coastal erosion, and are now replacing detached breakwaters. Although constructions of the artificial reefs sometimes cause significant score around the reefs, the manuals for the design describe mainly on wave decay. An opening between artificial reefs shows typical scouring like a corn at the offshore of the middle of the opening. To estimate a topographic change, we need the distributions of water surface elevation and the bottoms currents. In this research, we investigated the ability of a fully nonlinear Boussinesq model around an opening with the eddy viscosity model for wave breaking. This paper shows that the numerical results have good agreement with experiments wave surface distributions and bottoms currents.

It is difficult to measure the salt-water intrusion in the field though the environment of the Lake Ogawara consists on a delicate balance of the salt-water intrusion and the salinity circulation. In this study, the amount of the salinity outflow-inflow is estimate respectively by a multiple linear regression analysis and fuzzy reasoning by using only the water level of the river mouth and the Lake Ogawara. The tendency of the amount of the salinity outflow-inflow in winter was able to estimate by the both of a multiple linear regression analysis and fuzzy reasoning.

From the diazocoupling reaction between 4-chlorocatechol and the silica gel which was modified by aminophenyl-trimethoxysilane, an adsorbent is obtained. By using this absorbent, the present paper describes the preconcentration of Cu(II) based on chiefly the column method. The maximum amount of Cu(II) adsorbed by the adsorbent is 0.2m mol per gram at pH 5.2. When aqueous solution containing Cu(II) (pH 5.0 to 5.5) is put through the column (adsorbent 75mg) , the adsorbent adsorbs it instantly, which accords with the ratio of concentration up to the range of 5.0×10^<-7>〜1.0×10^<-4> mol/l. The adsorbed Cu(II) is eluted by 5 ml hydrochloric acid (0.1 mol/l) solution. The concentration of Cu(II) in the elution was determined by the FIA.

As many members come from the wide areas in Aomori prefecture, the exercise is suspended unwillingly from the end of the college year to the early spring. By analyses on how the above exercise suspension influences on the body composition, physique and physical fitness of members of the female basketball club in our college, following results are obtained: 1) Weight is almost the same; 2) Although %FAT increases slightly, no significant difference is recognized; 3) FM increases slightly, but no significant difference is recognized; 4) LBM decreases for seven members among ten, and the obvious decrease of the average is recognized at 5% significant level; 5) The average of backstretch decreases slightly, but no significant difference is recognized; 6) V0_2max of all ten members decreases, and the obvious difference is recognized at 0.1% significant level; 7) Ability of all members decreases on how many meters they can run during twelve minutes, and the obvious difference is also recognized at 0.1% significant level; From the above results, followings are confirmed: Viewed from the body composition, nevertheless the rates of increase on %FAT and FM are less than male members, the above exercise suspension causes LBM to significantly decrease similarly to male members; Viewed from physical fitness, achievable distance with running in twelve minutes which is not measured for male members and VO_2max decrease significantly, and obvious influence on heart-lung capability is verified. Suspension causes endurance of physical fitness degradation, careful selection of training menu, therefore, must be considered as re-starting the exercise.
