Experimental study and modeling of pressure loss for foam-cuttings mixture flow in horizontal pipe

In this study,we first sought to elucidate foam rheology to describe foam flow behavior,and then to experimentally investigate the pressure losses for both foam and foam-cuttings flow in a horizontal pipe by considering both varied foam qualities of 80%, 85% and 90% and foam velocities.Also,a two-layer numerical model to predict pressure loss was developed based on experimental observations of cuttings behavior.Results show that the foam behaves like a power-law fluid.Furthermore,and the pressure loss signi...     

L2-bounded stability for a stochastic system†

Both types of linear and non-linear systems with random coefficients are treated in this paper. Four theorems are proved by using the stochastic Liapunov functional, which give the sufficient condition in matrix form for exponential asymptotic stability in the largo with probability one and L₂-bounded stability with probability one.     

Protein-Protein Interaction of Fish Myosin Fragments

Protein-protein interaction of myosin fragments from flying fish and white marlin muscles was studied by means of absorbance changes resulting from aggregation at temperatures of 20°C to 70°C. Subfragment-1 (S-1) exhibited a high extent of interaction with the transition temperature of 35–36°C, while the interaction of heavy meromyosin (HMM) was very weak. Though light meromyosin (LMM) gave lower interaction values throughout the heating temperature, the addition of butanol promoted markedly the interactions at the temperature above 50°C. The degree of promotion was high for flying fish and low for white marlin.     

SAFETY EXAMINATION OF SOME EDIBLE OR MEDICINAL PLANTS AND PLANT CONSTITUENTS, PART 3

The carcinogenicity of vicia, galanga, lathyrus and lycium, which are plants used as human food or in folk medicine, and of caffeic acid and prunasin, which are plant constituents, was examined in an inbred strain of ACI rats. Fresh plant materials were dried, milled and mixed with the rat basal diet in the ratio of 16% and 33% of the total. The plant constituents, caffeic acid and prunasin, were mixed with the basal diet in the ratio of 0.5% and 0.03%, respectively. These diets were administered to rats for periods ranging upward from 180 days. Carcinogenic activity was not observed with any of the plants or plant constituents.     

Study on Construction of Industrial Large‐Scale Battery System

This paper proposes a construction method for battery systems that are widely used in industries. The battery system uses a building block structure combined with a battery module, whose capacity is less than 1 kWh. To manage the building block structured system, we propose a hierarchical structured management method. In each hierarchy, the voltage and temperature of the battery are monitored, and the information necessary for calculating charge states and detecting faults are sent to the upper hierarchy for the state management of the lower hierarchy. Furthermore, to ensure the safety during maintenance activities, we provide a guidance for understanding the insulation structure for the battery module, and develop a ground fault detection method that detects a decline in the insulation performance by using a rising method. For the experiment, we use a 30‐kWh trial manufacture battery system combined with the hierarchical management method. We verify that charge states and faults are detected in the battery of the system, and confirm that the system can be charged and discharged safely.     

Calcium Fortification of Soy Milk with Calcium-Lecithin Liposome System

Calcium ion was enveloped with a membrane system before addition to soy protein to prevent soy protein from being coagulated and precipitated by calcium ion. Soy lecithin was first sonicated in calcium salt solution to envelop the calcium ion with a liposomal structure composed of lecithin. Then, the calcium-lecithin liposomes were added to soy protein solution. Precipitation and coagulation were not observed in this soy protein-lecithin liposome system containing 60 mM Ca²⁺. By this method, it was possible to prepare calcium fortified soy milk containing more calcium (120 mg/100g) than in cow's milk. These results suggest that this calcium-lecithin liposome system is useful for calcium fortification of soy milk.     

Ferroelectric Properties of Mo-Doped Bi4-XLaXTi3O12 Films

Mo-doped Bi_3.35La_0.75Ti₃O₁₂ (BLTM) films were deposited on Pt/Ti bottom electrodes by using a sol-gel method and crystallized at 700°C for 30 min in O₂ atmosphere. The ferroelectric properties were greatly improved by substituting B-site ions with Mo ions and the BLTM films showed strong preferred (117) orientation. Typical remanent polarization (2Pr) and coercive field (2Ec) values were 32.0 μC?cm^?2 and 158 kV?cm^?1, respectively. It was also found that the leakage current densities in the BLTM films were lower than those in Bi_3.35La_0.75Ti₃O₁₂ (BLT) films.
