TL;DR: Evidence is presented indicating that, under certain circumstances, variant cells can exercise a contact-inhibition of the growth of their revertants, and possible physiological bases of the variriant's cultural properties are discussed.
Abstract: A heretofore undescribed minute-rough colonial variant has been isolated from cultures of a red, adenine auxotroph ofCandida albicans, strain WC—7. The variant has been detected only in WC—7 populations which are propagated at 37° C on very low concentrations of adenine. It produces colonies much smaller than those of WC—7 at both 25° C and 37° C on defined media containing either ammonium ion or casein hydrolysate as nitrogen sources. On ammonium nitrogen, young variant colonies are smooth and contain only typical yeast cells. While colonies which grow at 37° C retain these characteristics upon extended incubation, those growing at 25° C progressively roughen due to extensive development of pseudohyphae as the glucose levels in their vicinities decline. Under comparable conditions, colonies of the parental strain WC—7 remain smooth and free of pseudohyphae, Supplementing the medium with large amounts of glucose, intermediates of the tricarboxylic acid cycle or any one of several amino acids biosynthetically derived from intermediates of oxidative respiration prevents formation of pseudohyphae by the variant without significantly affecting its growth rate. Genetically, the variant is unstable and reverts frequently to a stable, rapidly growing form apparently identical to strain WC—7. Evidence is presented indicating that, under certain circumstances, variant cells can exercise a contact-inhibition of the growth of their revertants. Possible physiological bases of the variriant's cultural properties are discussed.

TL;DR: In this article, student personnel administrators from 48 junior colleges and 45 four-year institutions identified how they distributed their professional time, the importance they attributed to 15 job functions, the relative importance they attached to academic and on-the-job training in preparing for the 15 functions, and the substantive areas they felt appropriate for graduate programs to emphasize.
Abstract: Student personnel administrators from 48 junior colleges and 45 four-year institutions identified how they distributed their professional time, the importance they attributed to 15 job functions, the relative importance they attached to academic and on-the-job training in preparing for the 15 functions, and the substantive areas they felt appropriate for graduate programs to emphasize. While on-the-job training was generally viewed as more helpful than academic preparation, the latter was perceived as at least relevant to most administrative activities. There were some differences both in the type of training recommended and in the nature of the work done by the two groups of administrators. However, in view of their general similarity, it was concluded that the unique needs of each could probably be met in a single graduate program if requirements are reasonably flexible and if satisfactory practicum-internship facilities are available in both the junior and senior college settings.

TL;DR: A survey of 315 organizational members suggests that influence, information, and formal education are positively and significantly correlated with one's perception of the importance of organization as discussed by the authors, indicating that influence and information are positively correlated with the perceived importance of organizations.

TL;DR: The burst of motion resulting from injection of KCl near the supra-esophageal and mesothoracic ganglia were, by far, the most persistent and lead one to speculate on their possible role in normal ventilatory events.

TL;DR: Argillites of the Permian Mount Glossopteris Formation were analyzed for clay minerals, trace elements, and phosphate paleosalinity and found a salinity range of 29 to 33 parts per mille, designated the "paleosalinity signature" of the formation.
Abstract: Argillites of the Permian Mount Glossopteris Formation were analyzed for clay minerals, trace elements, and phosphate paleosalinity. Mainly degraded and stripped illites occur. The determined salinity range, 29 to 33 parts per mille is designated the "paleosalinity signature" of the formation. Analysis of trace elements supports phosphate paleosalinity determinations. Data from Leaia- bearing beds indicate a salinity range of 30 to 31 parts per mille that persisted some 137 years. Subsequent increase to 33 parts per mille corresponded to termination of leaiid occupancy of the area. These findings confirm and extend Nelson's study of phasphate paleosalinity.

TL;DR: The spastic children were superior to athetoid children on ratings of speech intelligibility and ability in articulation, and no significant differences were found between subclasses in auditory decoding as measured.
Abstract: Five measures of speech and linguistic ability were used to evaluate differences between athetoids and spastics matched on CA and IQ. The measures used were Integrated Articulation Test, speech articulation ratings, Abstraction Test, Sound Discrimination Test, and the Peabody Picture Vocabulary Test. The spastic children were superior to athetoid children on ratings of speech intelligibility and ability in articulation. The differences between the two groups on the sound discrimination, abstraction and vocabulary tests were nonsignificant, thus no significant differences were found between subclasses in auditory decoding as measured.
TL;DR: In this paper, minor clarifications are made in the mathematical aspects of the theory of moving-boundary electrophoresis, mostly related to the property of mean-square asymptotic stability (or the mean square uniqueness of a steady state that sets in very quickly).
Abstract: Some minor clarifications are made in the mathematical aspects of the theory of moving-boundary electrophoresis, mostly related to the property of mean-square asymptotic stability (or the mean-square uniqueness of a steady state that sets in very quickly). This property, which should be of some interest to those who use electrophoresis as a tool, is proven for a simple reacting system (as well as for a nonreacting system) previously studied by John R. Cann of the University of Colorado Medical School. Here we assume that a certain reaction rate function is nondecreasing and some comments are made relative to properties of solutions. It is emphasized throughout that both boundary specifications and prescriptions of values on the boundary can be kept finite and can be prescribed in such a way that regular solutions exist. It is felt that this serves to make physical interpretations of solutions easier for empirical investigators.
TL;DR: In this paper, a photogrammetric method for the determination of the generating parameters of a photograph is presented, defined as six independent coordinates from which a photograph may be geometrically reproduced by considering a large number of points in the 3D object space and transforming these to the 2D space of the photograph.
Abstract: A photogrammetric method for the determination of the generating parameters of a photograph is presented. The generating parameters are defined as six independent coordinates from which a photograph may be geometrically reproduced by considering a large number of points in the three-dimensional object space and transforming these to the two-dimensional space of the photograph. These parameters consist of the coordinates of the point where the camera is located, the symmetric equations of the line along the optical axis of the camera, and a linear scale factor associated with the photograph, enlarged to any magnification. The desired six parameters are iteratively determined by the method of least squares by considering five or more points in the object space whose rectangular coordinates are known or may be estimated with a high degree of accuracy. Good agreement with experimental results was obtained and an application is described.
