Determination of water in cooked cottonseed meats by a modified indirect conductivity method

Summary The modified indirect conductivities and oven-dry moisture percentages were determined on mine Samples of cooked cottonseed meats (1.8 to 13.9% water). Statistical treatment of the data yields the following results: (1) equation of the regression line, {fx177-1} (2) correlation coefficient, 0.998; (3) standard deviation from the regression line, 0.27% water. Ten replicate determinations made on each of two samples containing 2.7 and 7.7% water showed standard deviations of 0.07 and 0.08% water. These results show that the accuracy and precision of the modified indirect conductivity method are satisfactory for practical applications. For a consecutive series of determinations the average time required per determination was about 9 min. This time could be reduced to about 5 min. by using duplicate sets of stirring apparatus.

Pain threshold values during periodontal probing: assessment of maxillary incisor and molar sites

Probing pain threshold (PPT) assessments were conducted in the facial and oral sulci of maxillary central incisors and first molars of 10 periodontally healthy adults. All subjects were systemically healthy, free of pain, and reported no current medication usage. A computer-linked electronic probe, modified to deliver steadily increasing forces up to 200 grams, was used to collect the data. The system contained a subject operated "off-switch" which, upon activation, signaled the computer to record the subject's PPT. Assessments of each subject's PPTs were conducted on 3 separate occasions at 7-day intervals. Results indicated that the facial sulci of the incisors were the most pain sensitive. They displayed a mean PPT of 50.9 +/- 26.6 grams. The oral sulci of the incisors exhibited a mean PPT of 76.5 +/- 45.2 grams. Facial and oral sulci of the molars evidenced mean PPT values of 102.6 +/- 52.1 grams and 113.5 +/- 51.3 grams, respectively. These data suggest that sulci associated with incisor teeth are nearly twice as pain sensitive as sulci associated with molar teeth. In addition, facial sulci are significantly more pain sensitive than oral sulci. Data did not indicate a visit effect nor a side-of-mouth effect on PPT values.     

Effects of hypothalamic temperature changes on the sweat rate in Macaca mulatta

The concept of cardiac reconditioning centers for the prevention and rehabilitation of coronary patients has been tremendously successful in Germany over the past 20 years. At least 40 such centers are located throughout the country. Physicians, nurses, and physical therapists work closely together in the various facets of the rehabilitation process. The financial backing for these facilities is primarily through governmental and regional insurance companies, whose officials are apparently convinced that in the long run supporting preventive measures is financially sound. Objective data supporting their convictions come from studies such as that of Brusis, who showed that such as that of 1,500 employees was diminished by nearly 70 percent during a two-year period after cardiac reconditioning, as compared to a similar time period before the rehabilitation experience. Subjective benefits, which are extremely difficult to quantitate in meaningful terms, were nonetheless expressed by nearly all the patients with whom I conversed. Perhaps they have experienced the same feelings that Mark Twain did when he observed that "all frets and worries and chafings sank to sleep in the presence of the benignant serenity of the Alps; the Great Spirit of the Mountains breathed his own peace upon their hurt minds and sore hearts and healed them."     

Evaluation of Slip Feed System for Vapor-Phase Bioreactors

This study evaluated the ability of a slip feed system to maintain the pollutant-degrading activity of biomass in a vapor phase bioreactor during periods of little or no contaminant feed. Three slip feed fractions (1, 5, and 9% by mass) were investigated in a bioreactor treating toluene-contaminated air. Results indicate that the slip feed system improved the contaminant degradation capacity in the carbon-deprived bioreactor zones by approximately 30% regardless of the slip feed fraction supplied. This yielded a 10–20% improvement in toluene removal efficiency when the entire bioreactor column was subjected to a sudden threefold spike in toluene loading. When a 12% slip feed was supplied to the bioreactor during a short-term (3 days) or longer-term (1 week) shutdown period, it reduced the reacclimation time required following restart by as much as 70%. These results indicate that as long as the biomass receives at least a trace of the pollutant by means of a slip feed system, it can maintain sufficient pollutant degrading capacity to respond quickly to pollutant loadings upon restart.     

Expert system detection of drug interactions: results in consecutive inpatients

Although drug interactions (DI) are a common cause of morbidity, their large number precludes remembering them. To address this problem, we constructed a microcomputer-based expert system and assessed its efficacy in 90 consecutive inpatients. It was found that, without the expert system, a knowledge of the patient's medication list did not affect the frequency of occurrence of DI. Also, without the expert system, no DI were predicted, clinically, whereas the expert system predicted 27 DI of which, in retrospect, 10 actually occurred. Unsuspected DI were most likely if: a drug was not within the specialty of the clinician, DI host factors were present, or the DI involved a commonly prescribed drug pair. Although none of the drug interactions were life-threatening, in two cases, the DI was the cause for admission. Since the offending medications could usually be adjusted in dose, drug interactions were easily corrected once clinicians were made aware of them.     

Photoelectric properties of MISM phthalocyanine structure

Langmuir-Blodgett films have been prepared from copper tetra-4-t-butylphthalocyanine. A voltage dependence of capacitance can be attributed to the presence of a Schottky depletion layer. The barrier potential was determined as l·4eV, and the carrier concentration about 10²⁴m^?3
