Construct Validity of the Teate Depression Inventory and the State-Trait Inventory for Cognitive and Somatic Anxiety
The current study replicated previous research by examining convergent and discriminant validity of the Teate Depression Inventory (TDI), the General Behavior Inventory (GBI), and the State-Trait Inventory of Cognitive and Somatic Anxiety (STICSA). Results supported convergent validity between the TDI Total score and the GBI Depression subscale and discriminant validity was supported by the correlations between the TDI Total and GBI Hypomania-Biphasic subscale and the STICSA State- and Trait-Somatic subscales. Interestingly, results supported convergent validity between the TDI Total score and the STICSA State- and Trait-Cognitive subscale. These results are discussed
Off-design correlation for losses due to part-span dampers on transonic rotors
Experimental data from 10 transonic fan rotors were used to correlate losses created by part-span dampers located near the midchord position on the rotor blades. The design tip speed of these rotors varied from 419 to 425 m/sec, and the design pressure ratio varied from 1.6 to 2.0. Additional loss caused by the dampers for operating conditions between 50 and 100 percent of design speed were correlated with relevant aerodynamic and geometric parameters. The resulting correlation predicts the variation of total-pressure-loss coefficient in the damper region to a good approximation
Reduction of Thiocyanate Complexes of Fe(III) in the Presence of Activated Carbon
Fe (III) complexed with SCN- was found to be reduced to Fe(II) in the
presence of activated carbon. The rate of disappearance of the complex was
determined spectro photometrically and was found to be first order with respect
to Fe(I1I). The enthalpy and entropy of activation are 100 ± 10 kJ/mole and
14.1 ± 0.8 J/mole-K respectively. Some Fe was found to be adsorbed on the
catalyst where the actual reduction was suggested to take place. The accompanying
oxidation reaction has been suggested to be mainly that of the thiocyanate
ions adsorbed at the positive centres on the catalyst
Changes in Surface Potential of Activated Carbon Due to Adsorption of Ions
The construction of a carbon electrode and the measurement of the changes in the potential that developed
on its surface as a result of adsorption of ions are discussed as a function of the cation adsorption and ionization of the functional groups on the surface of carbon
High-energy Modification Hydrates of Copper(II) Sulphate: heats of solution and infrared spectrum
High-energy modification of lower hydrates of copper(II) sulphate have been prepared and their
heats of solution measured. The values obtained are higher than previously found for the salt. A new
mechanism of dehydration has been proposed and supported by ir study of deuterated sample
Potential Measurements on Rubber Surfaces in Electrolyte Solutions
Films of natural and modified rubber were prepared and used as electrode membranes.
The potential developed varied with the concentration of ions in solution and is
discussed in terms of adsorption of the ions onto the membrane
Light trapping within the grooves of 1D diffraction gratings under monochromatic and sunlight illumination
The Rayleigh-Modal method is used to calculate the electromagnetic field
within the grooves of a perfectly conducting, rectangular-shaped 1D diffraction
grating. An \emph{enhancement coefficient} () is introduced in order to
quantify such an energy concentration. Accordingly, 1 means that the
amount of electromagnetic energy present within the grooves is larger than that
one will have, over the same volume, if the diffraction grating is replaced by
a perfectly reflecting mirror. The results in this paper show that can
be as large as several decades at certain, often narrow, ranges of wavelengths.
However, it reduces to approximately 20% under sunlight illumination. In this
latter case, such values are achieved when the \textit{optical spacing} between
the grooves is greater than 500 nm, where is the groove spacing and
is the refractive index of the substance within the grooves. For
smaller than 500 nm the enhancement coefficient turns negligibly small.Comment: This paper contains 11 pages and 4 figures, and will be published
