Influence of dialyzable compounds on the Theological properties (shear stress and shear strain at failure) of heat-induced whey protein concentrate (WPC) and whey protein isolate (WPI) gels was examined. Dialyzing WPC and WPI suspensions prior to gelation increased the stress of two of three WPC gels and a WPI gel. Dialysis also significantly increased the strain of the same two WPC gels, normalizing all strain values. Replacement of calcium lost through dialysis did not significantly change gel rheology. However, chelating calcium caused a significant decrease in the stress of all gels: a minimum amount of calcium and/or a calcium complex appears to have a major role in whey protein gelation. 相似文献

Emitted intensity was measured at 15° increments from the incident beam and around the equator of a honeydew melon which was irradiated with a near infrared beam. Signal strength was adequate up to 75° to provide a usable spectrum for NIR analysis of internal tissue. A noisy but recognizable spectrum was obtained at 180°. 相似文献

62 ALCOHOLIC PATIENTS WERE ADMINISTERED THE WITKIN ROD AND FRAME TEST BEFORE AND AFTER 8-10 WK. OF PSYCHIATRIC TREATMENT. THERE WAS SIGNIFICANTLY GREATER FIELD-INDEPENDENT PERFORMANCE FOLLOWING TREATMENT. THESE RESULTS TEND TO CAST DOUBT ON THE HYPOTHESIS THAT PERFORMANCE ON THE ROD AND FRAME TEST IS STABLE AND UNAFFECTED BY CHANGES IN BODY STATE.

IT WAS HYPOTHESIZED THAT RELIABLE AND VALID PSYCHOMETRIC EVALUATIONS OF YOUNG AUTISTIC CHILDREN ARE POSSIBLE WITH MEASUREMENTS AT APPROPRIATELY LOW DEVELOPMENTAL LEVELS. A MODIFIED 20-MIN INFANT TEST WAS ADMINISTERED AND READMINISTERED TO 14 5-YR-OLD AUTISTIC CHILDREN. INFANT TEST SCORES WERE CORRELATED WITH INDEPENDENT CLINICAL JUDGMENTS AND SOCIAL AGES AS DETERMINED BY THE VINELAND SOCIAL MATURITY SCALE. A TEST-RETEST R OF .93 AND ITEM ANALYSES DEMONSTRATED HIGH RELIABILITY. 4 OF 5 CORRELATIONS WITH VALIDATING CRITERIA WERE HIGHLY SIGNIFICANT. IT IS CONCLUDED THAT AUTISTIC CHILDREN (1) ARE NOT PSYCHOMETRICALLY UNTESTABLE, AND (2) MAY DIFFER FROM OTHER SEVERELY COGNITIVELY HANDICAPPED CHILDREN PRIMARILY BY VIRTUE OF HAVING FEWER MOTOR DISABILITIES.

3 MEASURES OF AGGRESSION-THE BUSS AGGRESSION MACHINE (BAM), ROLE-PLAYING (RP), AND THE BUSS-DURKEE HOSTILITY INVENTORY (BD)-WERE ASSUMED TO LIE ALONG A CONTINUUM OF THE BEHAVIORAL DIRECTNESS WITH WHICH THE AGGRESSIVE RESPONSE IS MADE. SS WERE 38 MALES. THE BAM WAS FOUND NOT TO RELATE TO ANY MEASURES, WHILE THE HYPOTHESIZED RELATIONSHIP BETWEEN THE BD AND RP WAS SUPPORTED. IN GENERAL, THE RESULTS DO NOT SUPPORT THE HYPOTHESIZED CONTINUUM OF RESPONSES. AN ALTERNATIVE INTERPRETATION OF THE RESULTS IN TERMS OF ORTHOGONAL PHYSICAL AND VERBAL MODES OF AGGRESSION IS DISCUSSED. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Studies of the USDA raw-pack process for home-canned tomatoes, using Bacillus licheniformis spores as the target organisms, revealed that water bath size and canning load did not affect heat penetxation rates in pint jars of tomatoes. However, because decreases in the water bath size and canning load shortened the come-up time and, as a result, lowered the maximum cold-spot temperature; the calculated process lethalities were lessened. Properly executed canning runs which varied in water bath size, amount of water in the bath, and load size produced calculated lethalities ranging between 1 and 7 log reduction. 相似文献
