A Suggestion on the Standard X-Ray Powder Diffraction Pattern of Barium Ferrite
Abstract We have examined the barium ferrite powder X-ray diffraction patterns in the PDF using experimental and calculated diffractograms. An improved calculated diffractogram is proposed. The result indicates that the primary peak of barium ferrite is not (107) but is (114).
Modeling of growth rate dispersion in batch cooling crystallization
Abstract The influence of growth rate dispersion on the product‐size distribution of batch cooling crystallization is investigated by computer simulations. The model accounts for primary and magma density‐dependent secondary nucleation, and growth rate dispersion of the constant crystal growth type. The model is solve…
The electronic structure and superconductivity of the lanthanum monochalcogenides LaX (X = S, Se, Te)
Abstract The first band structures and calculated electronic properties of the compounds LaSe and LaTe are reported. The energy band structure of lanthanum monochalcogenides are obtained using the self‐consistent LMTO method within the atomic sphere approximation. The band structure outputs were used to calculate the…
Numbering the crystallographic variants in phase transformation
In phase transformation one initial orientation gives rise to several final orientations called crystallographic variants. In this paper it is shown that the number of physically distinct variants depends not only on the lattice symmetry of the initial phase but also on the mutual orientation relations between the lat…

In permanent magnetic materials magnetization reversal does not take place by coherent and global rotation.No collective processes are involved when the energy barrier implicated in the reversal is of magnetocrystalline nature acting at the atomic level.The mechanism by which magnetization reversal occurs involves sev…
Real‐time X‐ray scattering study of thermal expansion of poly(butylene terephthalate)
Abstract Real‐time x‐ray scattering at elevated temperatures has been used to investigate the thermal expansion characteristics of poly(butylene terephthalate), PBT. Changes in the six lattice parameters of the α‐form of PBT were obtained from wide‐angle x‐ray scattering over the temperature range from 35 to 215°C. Th…
Transmission electron microscopy in situ observation of crack propagation in sintered alumina
Abstract Crack propagation behaviour in sintered alumina has been observed by in situ straining experiments in a transmission electron microscope at 800°C. Dislocations were generated at the crack tips, and the strain contour line around the crack tips was found to oscillate periodically during crack propagation. Crac…
Electrophoretic Behavior of Imogolite under Alkaline Conditions
Abstract Electrophoretic mobility of imogolite has been reported as positive (migration toward the negative electrode) below pH 9, and zero above pH 9. However, when mobility of dilute imogolite suspensions (5 × 10 −3 kg/m 3 ) was measured, it was found to be negative above pH 9. The reason that imogolite does not beh…

The concentration dependence of the hole mobility of 1,1-bis(di-4-tolylaminophenyl)cyclohexane doped bisphenol-A-polycarbonate
Hole mobilities of 1,1,-bis(di-4-tolylaminophenyl)cyclohexane (TAPC) doped bisphenol-A- polycarbonate have been measured over a range of concentrations. The mobilities are strongly concentration dependent, increasing with increasing TAPC concentration. The results are described within the framework of the disorder for…
Extrudate swell of high density polyethylene. Part III: Extrusion blow molding die geometry effects
Abstract Two high density polyethylene resins—801 and 802— are examined with regard to their isothermal, time‐dependent, and nonisothermal swelling properties when emerging from two annular and three diverging dies. The short time swelling characteristics of samples 801 and 802 are very important for these dies, resul…
Extraction and Evaluation of Fibers from Sugar Cane
Sugar cane fiber bundles were extracted from the separated rind of cane stalks using alkaline treatments. The amount of lignin removed depended on alkaline concentration and time and pressure of treatment; agitation and vigorous boiling also affected the lignin removal. A severity factor R was calculated to compare th…

Scoparic Acid A, a β-Glucuronidase Inhibitor from Scoparia dulcis
The 70% EtOH extract of Scoparia dulcis showed inhibitory activity against beta-glucuronidase from bovine liver. Bioassay-directed fractionation of the active extract led to the isolation of three labdane-type diterpene acids, scoparic acid A [1] [6-benzoyl-12-hydroxy-labda-8(17), 13-dien-18-oic acid], scoparic acid B…
Structures of sodium metal
The martensitic transformation in sodium metal has been studied using neutron-diffraction and neutron-inelastic-scattering techniques. In two separate experiments the transformation was observed on cooling near 32 K. Measurements of the diffuse scattering, diffraction linewidths, quasielastic scattering, and the tempe…

SUMMARY In this first of three papers, the parent materials, morphology and field relationships of soils with fragipans, similar to those in north‐eastern United States, are described and analyses of their chemical and physical properties are presented to support a periglacial stage of development. The soil materials…
