Growth of Earth Science in the Secondary Schools in Ohio
(1969-11) Skinner, Ray, Jr.
A questionnaire survey of secondary-school principals revealed that there were 613 teachers teaching earth science in Ohio during the 1968-69 school year and that there were 50,180 students enrolled in earth science in 410 schools. Most of the schools are located in metropolitan centers in Ohio, but at least one school in 75 of the 88 counties in Ohio offers earth science. This survey revealed that Ohio should rank among the top several states in the number of students enrolled in a standard earth-science course.
Variations in the Appearance of Human Elastic Cartilage
(1969-11) Sucheston, Martha E.; Cannon, Marvin S.
Cartilage from the external ear, epiglottis, and auditory tube from 22 adult human cadavers, ranging in age from 52 to 64 years, and from seven newborn infants was examined microscopically to ascertain any morphological differences in structure. All cartilages from the newborn infants were hyaline, showing evenly dispersed chondrocytes and lack of elastic fibers, with the exception of the epiglottic cartilage, which possessed a few such fibers at this stage. In adult cartilages, the presence or absence and location of young growing, mature, and/or calcined chondrocytes is described. All cartilages had a PAS-positive matrix. The distribution of elastic fibers is denned. The differences in adult human cartilages are summarized and lead us to suggest the term elastoid as the name for the cartilage of the auditory tube.
Chilling and Translocation Inhibition
(1969-11) Geiger, Donald R.
The effect of chilling on translocation in higher plants was reviewed by separate consideration of path, sink, and source-cooling effects. The response of the sink to chilling indicates that the effect is mainly due to the inhibition of a metabolic process, while the response of the path to chilling suggests that the effect is mainly due to physical damage such as alteration of membranes. Sugar beet Beta vulgaris L. shows a rapid recovery of translocation during chilling, and bean Phaseolus vulgaris L. shows a very slow recovery; northern and southern ecotypes of Canada thistle, Cirsium arvense L., resemble beet and bean, respectively. Differing bases for chilling-inhibition mechanisms in the subdivisions of the translocation system are suggested by the analysis of kinetics of inhibition and recovery during localized chilling of these parts.

Nesting Success of the Bluegill, Lepomis Macrochirus Rafinesque, in a Small Ohio Farm Pond
(1969-11) Stevenson, Frederick,; Momot, Walter T.; Svoboda, Frank J., III
Some of the factors influencing the reproductive success of the bluegill sunfish, Lepomis macrochirus Rafinesque, in an Ohio farm poind were investigated during three summers from 1965 to 1967. The availability of nesting substrate was the major variable affecting spawning success in the pond. Fine gravel and sand substrates produced the most fry. Those of mud and debris produced less fry. Chemical control of algal mats in 1965 and 1967, by providing open areas of preferred substrate, increased nesting success and thus indirectly contributed to overpopulation of bluegills in the pond.
Summary of Ohio Tornadoes
(1969-11) Miller, Marvin E.
Ohio lies on the eastern edge of the maximum frequency belt for tornadoes in the whole world. Tornadoes approach from all directions, but about 90 percent come from the southwest, west-southwest, and west. As many as 32 tornadoes have been reported within the State in a single year and as few as none. During the period 1953-1968, Ohio averaged slightly more than 10 tornadoes a year. In contrast, reports of Ohio tornadoes prior to 1875 are especially rare. Upon examining these Ohio tornado statistics, one might conclude that there has been a great increase in the occurrence of tornadoes during the past 10 to 20 years. However, this can not be scientifically documented, and it is more likely that the apparent increase in numbers of tornadoes is due to the increased population and more efficient reporting procedures of more recent years. A brief resume of some of Ohio's worst tornadoes is given.
Relationships of Middle Silurian Strata in Ohio and West Virginia
(1969-11) Horvath, Allan L.
The Estill, Bisher, Lilley, and Peebles Formations crop out in Adams and Highland Counties, Ohio. All these units can be traced several miles eastward into the subsurface of the Appalachian Basin. Farther east, the Peebles and Lilley strata lose their distinctive lithology and become part of subsurface beds identified as Lockport by previous investigators. The Lockport beds intertongue with carbonates of the McKenzie Formation in eastern Ohio and western West Virginia. The "Clinton shale" of the driller shows a three-fold division in the subsurface of central Ohio: 1) upper dolomitic shales, 2) intermediate silty or arenaceous carbonates, and 3) lower green and brown clay shales. The upper and middle units can be traced from central Ohio southwestward into the Bisher, and the lower unit into the Estill Shale of southern Ohio. Eastward, near the Ohio-West Virginia boundary, the middle unit of the "Clinton shale" shows a facies relationship with the Keefer Sandstone. The lower unit of the "Clinton shale" can be traced eastward into the upper half of the Rose Hill Formation in West Virginia.
