Field independence–dependence and cognitive restructuring.

Investigated the hypothesis that field-independent (FI) individuals are more efficient in their use of cognitive restructuring skills than are field-dependent (FD) individuals. 32 FI and 32 FD female undergraduates, as assessed by the Hidden Figures Test, were required to solve a series of anagrams under either an easy or difficult anagram condition. Ss received 5 anagrams constructed from "social" words and 5 anagrams constructed from "nonsocial" words. The resulting repeated measures design allowed for an assessment of the performance effectiveness of FI and FD as well as an examination of the possible differential influences of word "socialness" and anagram difficulty. Analysis of anagram performance indicated that FI Ss found it easier than FD Ss to provide a disorganized field with organization. FI Ss solved the anagrams significantly quicker than did FD Ss. Consistent with this finding, FD Ss perceived the anagram task as being significantly more difficult than did FI Ss. (28 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Soap-based detergent formulations: XIII. Formulations with alpha-olefin sulfonates as lime soap dispersants

Heavy duty household type detergents were formulated from tallow soap-AOS(α-olefin sulfonate)-builder combinations. Various commercial AOS samples were evaluated. These were derived either from closely fractionated α-olefins such as C₁₄, C₁₆, and C₁₈ or from samples representing broader mol wt ranges such as C₁₄−C₁₆ and C₁₆−C₁₈. The builders incorporated into these combinations were a sodium silicate (Na₂O∶SiO₂=1∶1.6), sodium tripolyphosphate, sodium citrate, sodium carbonate, and trisodium nitrilotriacetate. Detergency evaluations of 0.2% solutions in 300 ppm hard water (as CaCO₃) were determined with three commercial soiled cloths and by a multiwash test in which clean cloth was repeatedly soiled and washed. The relative proportions of soap, AOS, and builder were varied to obtain maximum detergency, and comparisons were made to other soap-LSDA (lime soap dispersing agents)-builder combinations as well as to a commercial high phosphate detergent used as a control. Detergency performance of soap-AOS combinations ranked just below that of the commercial high phosphate detergent control and below that of soap formulations containing sodium methyl α-sulfotallowate.

Effect of buffer constituents on rat liver 3-hydroxy-3-methyl glutaryl coenzyme A reductase

Rat liver microsomes prepared in Tris buffer exhibited 3 to 10 times higher 3-hydroxy-3-methyl glutaryl CoA reductase specific activity than microsomes prepared with potassium phosphate buffer. This higher activity was observed in rats killed during mid-light cycle, but microsomes from rats killed during mid-dark cycle showed no significant difference in enzyme activity between buffers. When microsomes prepared in the 2 different buffers were preincubated with ATP and MG⁺⁺, enzyme activity was inhibited to the same extent. The cytosol fraction in each of the 2 different buffer preparations possessed similar phosphatase activity. The higher 3-hydroxy-3-methyl reductase activity in Tris buffer, therefore, does not appear to be due to differences in phosphorylation or dephosphorylation activity.     

Statistical detection and isolation of additive faults in linear time-varying systems

This paper describes a statistical approach to fault detection and isolation for linear time-varying (LTV) systems subject to additive faults with time-varying profiles. The proposed approach combines a generalized likelihood ratio (GLR) test with a recursive filter that cancels out the dynamics of the monitored fault effects. To our knowledge, the proposed recursive filter is new for the considered faults. The resulting algorithm handles fault isolation with weaker assumptions than usual, in particular regarding the requirements on the number of sensors and on the stability of the monitored system. Numerical results for leakage detection in a gas transportation network illustrate the effectiveness of the proposed method.     

The fractionation of lanolin with urea

Summary A fractionation of lanolin was effected by contacting lanolin with urea in the presence of methyl alcohol. About 6–8% of the lanolin formed a urea adduct which, upon decomposition, yielded a hard, nontacky wax fraction. In addition to the wax fraction, a fluid fraction and a sticky semi-solid were also obtained. The latter two fractions were obtained by the solvent extraction of the nonadduct-forming material from the urea adducts. The fluid fraction, obtained in 71% yield, is a viscous liquid at room temperature. The fluid properties of the fraction can be improved by acetylation.

Dodecyl acetate,a second pheromone component of the cabbage looper moth,Trichoplusia ni

Dodecyl acetate was identified as a second component of the sex pheromone ofTrichoplusia ni (Hübner). Dodecyl acetate comprised 9.6% by weight of the total pheromone [(Z)-7-dodecenyl acetate plus dodecyl acetate] extracted from glands and 7.3% by weight of the total pheromone evaporated from the surfaces of glands. Dodecyl acetate appears to function as a short-range pheromone component. Evaporation at female release rates of a 1090 mixture of dodecyl acetate and (Z)-7-dodecenyl acetate in the field caused a significantly greater percentage of males to land on the pheromone source, increased significantly the time they spent on the source, but decreased significantly the time they spent searching for the source when within 50 cm, as compared to (Z)-7-dodecenyl acetate alone.Lepidoptera: Noctuidae.     

The effect of dietary fats on the plasma lipid composition of sheep

This study reports on the plasma lipid compositions of sheep fed either a control diet (C), a control diet supplemented with tallow (A) or polyunsaturated fatty acid (B) that had been protected against hydrolysis and hydrogenation in the rumen, or a control diet supplemented with maize oil (D). Diet B considerably increased the 18∶2 content of all the major plasma lipid fractions. Although the feeding of diet D also resulted in an increase in the 18∶2 contents within the cholesteryl ester, unesterified fatty acid, and phospholipid fractions the increases were considerably less than those observed with diet B; the levels of 18∶2 within the triglyceride fraction remained similar to that for the sheep which received the control diet. The effect of feeding diet A was confined solely to the triglyceride fraction where the concentrations of 16∶0 and 18∶1 were increased. The lipoproteins of the plasma were separated into very low density lipoproteins (d<1.006), low density lipoproteins (1.006<d<1.063), and high density lipoproteins (1.063<d<1.21), and the distribution of the major lipids between these lipoprotein fractions was investigated. Diet B increased considerably the proportion of triglyceride found in association with the very low density fraction and the concentrations of 18∶2 within all the lipoprotein fractions; these increases in the concentrations of 18∶2 were not confined to any particular lipid fraction of the lipoproteins. In contrast, the increases in the concentrations of 18∶2 produced as a result of feeding diet D were confined to the low and high density lipoproteins. The effect of feeding diet A was confined to fatty acid changes within the triglycerides of the low and very low density lipoproteins.
