Some Observations Concerning The Evaporation Metals From Hot Filaments, M. Alden Countryman

Proceedings of the Iowa Academy of Science

For effective evaporation of metals from hot filaments, the metal to be evaporated, if different from the filament substance, must wet and cling to the hot filament used. A number of filament materials have been tried and the metals which wet each are reported.

Tensors And The Calculation Of Vibrational Frequencies Of Crystal Plates, R. G. Wilson, J. V. Atanasoff

Proceedings of the Iowa Academy of Science

A tensor method has been developed for the calculation of the frequencies of vibration of an infinite plate of any crystalline substance cut at any orientation. By the use of this theory a set of curves have been calculated showing the three characteristic frequencies for plates of quartz cut at various orientations. These results are in good agreement with the experimental work of the authors and other observers.

Resistivities Of Alloy Single Crystals, H. E. Way

Proceedings of the Iowa Academy of Science

A somewhat systematic attempt is being made to study the effect on electrical resistivity of zinc of small amounts of dissolved metallic impurities. In order to do this sets of single crystals have been made, each set containing a known percentage of some one impurity. The resistivities and some temperature coefficients of resistivity have been measured. The resistivity results include at the present data on sets of crystals containing 0.125, 0.25, 0.50 per cent of copper, gold, or silver, and 0.005% and.01 per cent iron. In all cases the resistivity increases with increase of added metal but not in a …

Notes On The Propagation Of The Large-Mouthed Bass Aplites Salmoides (Rafinesque) In Iowa, W. W. Aitken

Proceedings of the Iowa Academy of Science

The new artificial lakes of Iowa are particularly adapted for the large-mouthed bass (Aplites salmoides-Rafinesque), because the lakes are fed intermittently with run-off producing turbid conditions periodically, because large areas in the upper reaches of the lakes have suitable spawning areas, because crappie and bluegill do well in the same type environment, in turn becoming bass prey, because the warm waters of these areas have a proper amount of nitrogenous material necessary to stimulate growth of zoo-planton forms listed on the young bass bill-of-fare, and because the manmade lakes have sufficient depth to carry fish through severe winter months. There …

Research Vs. Conservation, W. W. Aitken

Proceedings of the Iowa Academy of Science

Conservation defined, means to supervise and protect. The supervising and protecting of wild life requires a knowledge of life history, habits, and daily activity of the particular objects under observation. This information is only gained after study and research into all factors effecting the life of plant and animal.

The Refractive Indices Of Alcohol-Water Mixture At 25º C, W. C. Oelke, Roger Arnold

Proceedings of the Iowa Academy of Science

The purpose of this project was to obtain a basis for the development of a laboratory experiment in Physical Chemistry on Minimum Boiling Mixtures. Alcohol and water were selected as the liquids to be used. The simplest and most accurate method for the determination of alcoholic percentage in such mixtures is by the means of refractive indices.

A Certain Persistence Of The Characteristics Of Structure Carried Over From Solid To Liquid With Alkali Halides, G. W. Stewart

Proceedings of the Iowa Academy of Science

Through density consideration it is shown that the alkali halides go over into a liquid form which is not random close packing, and evidently differs with body centered cesium halides. There is also a suggestion of a carry-over in aqueous solutions, this taking the form of "super arrangement" of ions in the electrolyte.

X-Ray Scattering From A Linear Charge Distribution, G. W. Stewart

Proceedings of the Iowa Academy of Science

In n-alcohols and n-paraffins the molecules lie parallel with such a configuration and distribution of scattering centers that one desires to know the character of x-ray scattering from a linear charge wherein there is a break in the continuity. The computation shows that a certain broken line charge will give a distribution of x-ray somewhat similar to that of two charges separated, not by the distance between their centers of charge but approximately 50 per cent more than this distance.

The Liquid Structure Of N-Aliphatic Alcohols, G. W. Stewart

Proceedings of the Iowa Academy of Science

There is substantial agreement that the molecules of n-aliphatic alcohols lie generally parallel, with the alternate ends of a longitudinal series of molecules being a pair of polar ends and a pair of non-polar ends. The suggestion has been made that there is no transverse space relationship of the polar pairs. The reasons for and against this suggestion are stated and it is concluded that there is high probability that their polar groups in n-alcohols do have a three dimensional space relationship in the liquid state.

X-Ray Extinction In Piezoelectrically Oscillating Quartz, J. R. Frederick, G. W. Fox

Proceedings of the Iowa Academy of Science

Fox and Fraser¹ have investigated the extinction of x-rays in piezoelectric quartz crystals by photographic methods for both the oscillating and non-oscillating cases. Apparent increased blackening of the photographic plate was observed for both the diffracted and central x-ray beams. Jauncey and Deming ² have performed a similar experiment on extinction using an ionization chamber and electrometer and have obtained results which are in disagreement with those of Fox and Fraser in regard to the central beam. We are repeating these observations using an ionization chamber and an electrometer tube to check the results of either of the above …

Some Observations On Teaching Bright Students, C. J. Lapp

Proceedings of the Iowa Academy of Science

During the summer of 1935 bright students who were finalists in the Iowa Academic Meet in Iowa high school physics were given college physics throughout the first six weeks of the summer session. These bright boys were under intensive observation during this period. Many unusual reactions were observed.

An Opportunistic Laboratory, John A. Eldridge

Proceedings of the Iowa Academy of Science

A laboratory has a joint function (a) to create happy attitudes and (b) to teach subject matter practically and realistically. It has sometimes been questioned whether the laboratory does act effectively either as inspiration or as a teaching device. The paper describes experiences in a laboratory where the experiments were exactly correlated with the class work, where laboratory manual was dispensed with, where the experiments were usually unconventional.

Semantic Psychology, O. M. Norlie

Proceedings of the Iowa Academy of Science

Semantic psychology is the psychology of language. This paper will call attention to the need of a more psychological alphabet.

Are There Types Of Learning And Thinking That Are Functionally Distinct, And If So, What?, Robert Leeper

Proceedings of the Iowa Academy of Science

The field covered by the concepts of learning and thinking is so extensive, and includes such a diversity of concrete material, that it would be very surprising if all could be covered by the same explanatory subject matter. If the field is heterogeneous, effective research on learning and thinking is contingent upon the classification of these materials into functionally distinct groups. Relatively little attention has been paid to this problem, however, and much of the discussion that has existed has been patently superficial (maze learning an example of "motor habits," e.g.). The present paper discusses the basis for such classificatory …

Time Characteristics In The Word-Association Test, Harold M. Williams

Proceedings of the Iowa Academy of Science

It has been repeatedly demonstrated that the word-association test empirically differentiates normals from delinquents and psychopaths, as well as a state of emotional calm from one of apprehension in a given subject. It is still relevant, however, to inquire more deeply, if possible, into the psychological nature of the process.
