Single crystalline elastic constants of the MgCu/sub 2/-MgZn/sub 2/ system (open access)

Single crystalline elastic constants of the MgCu/sub 2/-MgZn/sub 2/ system

The adiabatic single crystalline elastic constants of six Mg(Cu, Zn)/sub 2/ cubic Laves phases have been determined by the ultrasonic pulse-echo technique over the compositional range 10 to 50 mol % MgZn/sub 2/ and over the temperature range 4.2 to 300/sup 0/K. In addition the elastic constants of the hexagonal MgZn/sub 2/ Laves phase were measured as a function of temperature. A minimum exists in the compositional dependence of the cubic Mg(Cu, Zn)/sub 2/ phase at 20 mol % MgZn/sub 2/ for all three directly measured values and the anisotropy ratio shows a maximum at the same composition. These phenomena may be related to the fact that their Fermi surface touches the (311) faces of the Brillouin zones at this composition. The various energy contributions to the elastic shear constants were considered and it was concluded that the Fermi energy has to be included to achieve satisfactory agreement between the calculated and measured elastic constants. The Debye temperatures were calculated and were found to decrease at low zinc contents and then increase at compositions above 20 mol % MgZn/sub 2/ for the cubic Mg(Cu, Zn)/sub 2/ phase. The initial decrease is probably due to the substitution of the heavier zinc …

Predicting Student Teaching Behavior from Needs Profiles by Comparison with Sociometrically Defined Groups (open access)

Predicting Student Teaching Behavior from Needs Profiles by Comparison with Sociometrically Defined Groups

The problem of this study was the prediction of aggressive, submissive, and normal student teaching behavior by the use of needs profiles from sociometrically defined groups of education students. The criteria profiles were constructed using beginning education students, and prediction was made on a student teaching population.

Magnetic Exchange in Oxovanadium(IV) Complexes with N-Salicylideneamino Acids (open access)

Magnetic Exchange in Oxovanadium(IV) Complexes with N-Salicylideneamino Acids

Copper(II) and oxovanadium(IV) ions resemble one another magnetically in having one unpaired electron in their complexes irrespective of their geometrical structures and bond types involved. Copper(II) complexes with antiferromagnetic exchange are well known. On the contrary, antiferromagnetic exchange in oxovanadium(IV) complexes is rather new and not well established. Very few oxovanadium(IV) complexes have been reported to have this anomalous magnetic property. In the investigation of the magnetic properties of oxovanadium(IV) complexes, we have successfully prepared two series of new oxovanadium(IV) complexes with N-salicylideneamino acids.

Effects of Frustration Tolerance Training on Young Institutionalized Retarded Children (open access)

Effects of Frustration Tolerance Training on Young Institutionalized Retarded Children

The major problem investigated was to ascertain the extent to which a training program designed specifically to increase frustration tolerance would reduce selected behavioral problems in institutionalized mentally retarded children. Of lesser importance was the problem of examining the extent to which the prescribed training program had differential effects on brain-injured and non-brain-injured retarded children.
