Temperature-Time Relations In Canned Foods During Sterilization, George E. Thompson

Proceedings of the Iowa Academy of Science

Bacteriologists have found that the death rate of the bacteria which cause spoilage in canned goods depends upon the temperature to which the bacteria are subjected. In order, therefore, to establish the bacteriology of canning on a firm scientific basis it is necessary to know the time at which certain critical temperatures are attained by the foods which are subjected to the sterilization process. This paper shows the result of an attempt to work out by a combination of mathematical theory and experiment the temperature-time curves for certain foods in containers of any size and for any practical temperature range.

Note On The Tungsten X-Ray Spectrum (L-Series), O. B. Overn

Proceedings of the Iowa Academy of Science

A rather incomplete report of the work of Dershem on the X-ray spectrum of tungsten has appeared in the proceedings of the Iowa Academy of Science, A complete report is to be found in the Physical Review of June, 1918, where he finds this spectrum to contain 19 lines in the L region. Further experiments have been carried on using the same apparatus and method as used by Dershem, but increasing the time of exposure, with the result that six new lines have been discovered.

Stroboscopic Velocities In The Tonoscope, H. R. Fossler, L. E. Dodd

Proceedings of the Iowa Academy of Science

The characteristic equation for stroboscopic velocity is v₈ = (A-n/m B) D₀ (see Proc. Iowa Acad. Sci., Vol. XXIV, 1917, p. 222), where v₈ is the stroboscopic velocity, A the frequency of the stroboscopic figures, B the frequency of illumination, n/m a fraction at lowest terms, and D₀ the distance of separation of the stroboscopic figures.

The President's Address - Does The History Of Science Have A Place In The College Curriculum?, L. S. Ross

Proceedings of the Iowa Academy of Science

In order to understand a government at any stage of its existence it is necessary to understand how it came to be, what were its antecedents and under what conditions it was developed. In short its inheritance and its environment must he known. No complete understanding of present day civilization is possible without a knowledge of the civilization of the "Men of the Old Stone Age" and of the various phases of man's attempts, failures and successes, between these two stages. In other words the master anatomist and physiologist must be an embryologist. To comprehend and understand the completed structure …

On The Coefficient Of Absorption Of Photoelectrons In Silver And Platinum, Otto Stuhlman Jr.

Proceedings of the Iowa Academy of Science

The coefficient of absorption can be defined by the constant ^α in the exponential relation N=N₀e-a^t. The precise physical interpretation of such an exponential law when applied to a beam of electrons moving through a metal plate of thickness "t" is not so simple as its mathematical expression would lead one to suppose. It may, however, lie interpreted if we assume that there exists no "scattering" or energy transformation as the beam of electrons passes through the metal. If ^α x is taken as that fraction of the number which is absorbed when the beam of …

Some Fundamental Concepts Of Earth History, James H. Lees

Proceedings of the Iowa Academy of Science

We have been accustomed to think, most of us, that in the early days of the world's geologic history Nature manifested herself in forms different from those with which we are familiar; that God, the supreme Power of the universe, employed other types of energy than those by means of which He works today. And these conceptions have been fostered and influenced very largely, consciously or unconsciously, by our religions and theological training.

On A Supposed Fruit Or Nut From The Tertiary Of Alaska, A. O. Thomas

Proceedings of the Iowa Academy of Science

In the summer of 1910, Dr. George F. Kay, while engaged in a study of the Bering River Coal Field of southeastern Alaska, discovered some subspherical, concretion-like bodies in the ''shales of the Tokun formation.'' Three specimens were brought back by Professor Kay and these through his kindness have been submitted to the writer for study. The largest is a smooth oval body with long and short diameters of 8.6 and 7.6 centimeters; the smallest is likewise smooth, irregularly oval, and with diameters of 4.3 and 3.8 centimeters. All three are dark-colored, compact, close-grained stone, brittle under the hammer, and …

The Stroboscopic Effect, L. E. Dodd

Proceedings of the Iowa Academy of Science

Consider a straight row of equally spaced white dots on a black belt running at a constant velocity v over two pulleys. Let the dot spacing be D₀. Suppose that the belt is in a darkened room so that even when the belt is at rest the dots are invisible. Let the moving belt be periodically illuminated by some source of intermittent and approximately instantaneous illumination of constant frequency B.

A Physical Representation Of The Summation Of Certain Types Of Series, L. P. Sieg

Proceedings of the Iowa Academy of Science

Most of us are on the lookout for concrete illustrations of abstract ideas. To be able to visualize a mathematical process is to many of us a step toward the better understanding of that process. The following brief discussion, although having no pretentious to absolute originality, is offered as a physical illustration of the summation of certain simple geometric series.

A Modern School, Abraham Flexner

History of Education Book Gallery

A Modern School is a 23-page occasional paper, written by Abraham Flexner and published in 1916 by The General Education Board. Flexner (1866-1959) was an American educator and education reformer. The occasional paper presented here addresses many of the perceived failings of the public school system circa 1916 and suggests several reforms. The General Education Board was established by John D. Rockefeller in 1903. According to the Rockefeller Foundation, the board was established to aid education in the U.S. without distinction of race, sex or creed, and was active in promoting the public school movement in the early part of …

Controlling Fault Systems In Iowa, Charles Keyes

Proceedings of the Iowa Academy of Science

With its even plains surface, the infrequency of bed-rock exposures, and the universal presence of thick till or loess mantles, detailed geologic mapping of the prairie states is attended by many inherent difficulties not met with in more broken country. In consequence of the existence of these unusual conditions the consideration of possible noteworthy geotectonic features in the region is largely neglected. Anything beyond a few of the most obvious local characters completely fail of record. Over a very large part of the Mississippi basin the tectonics are commonly treated as if there were none at all. It seems to …
