On the appearance of Mach bands in gradients of varying color
(Elsevier, 1971-10)
Red and green triangular-wave intensity distributions were generated on cathoderay oscilloscope tubes. When these patterns are viewed separately, light and dark Mach bands appear at the peaks and troughs of the intensity ...
Reactions of patients during pregnancy of the psychotherapist
(Kluwer Academic Publishers; Behavioral Publications, Inc. ; Springer Science+Business Media, 1971-06)
A variety of patient reactions to the therapists' pregnancies have been described. Although the reactions varied, the central themes of rejection, sibling rivalry, and oedipal strivings were evident. In addition, material ...
Solvolysis of p-nitrophenyl esters catalyzed by oligo-4(5)-vinylimidazoles
(Elsevier, 1971-09)
The preparation of low molecular weight poly-4(5)-vinylimidazole is described. Oligomer fractions with molecular weight ranges from a few hundred to two thousand, five hundred were obtained by fractionation through a ...
The counterphobic defense in children
(Kluwer Academic Publishers; Behavioral Publications, Inc. ; Springer Science+Business Media, 1971-03)
The clinical data for this study were derived from the case histories of five children who consistently used the counterphobic defense either alone or in combination with phobic attitudes. The children's manifestations of ...
Computer simulation of a living cell: Part II
(Elsevier, 1971-07)
This paper, which is being presented in two parts, is concerned with the problem of a realistic and useful simulation of a living cell, the simple unicellular bacterium Escherichia coli, the program being written in Fortran ...
Computer simulation of a living cell: Part I
(Elsevier, 1971-04)
This paper, to be presented in two parts, is concerned with the problem of a realistic and useful simulation of a living cell, the simple unicellular bacterium Escherichia coli, the program being written in Fortran IV for ...
Time variations of lead, copper and cadmium concentrations in aerosols in Ann Arbor, Michigan
(Elsevier, 1971-08)
The atmosphere in Ann Arbor, 50 km west of Detroit, was sampled for aerosol particles for 2-h periods over a 42-h interval Friday to Sunday, April 26-28, 1968, using a modified seven-state Andersen cascade impactor and a ...
Area-wide distribution of lead, copper, and cadmium in air particulates from Chicago and northwest Indiana
(Elsevier, 1971-10)
Published air pollution emissions inventories for the urbanized and industrialized area along the southwestern shore of Lake Michigan include few chemical analyses of particulates, and estimates of the elemental composition ...
Diurnal variations of aerosol trace element concentrations as determined by nondestructive neutron activation analysis
(Elsevier, 1971-06)
Diurnal concentration variations of 20 trace elements in surface air have been studied over a 34-h period in a rural area. Twenty-five millimetre polystyrene air filter samples were taken each 90 min and analyzed by ...
