A Variant Quercus Alba L., J. N. Martin Jan 1934

A Variant Quercus Alba L., J. N. Martin

Proceedings of the Iowa Academy of Science

In a group of three white oaks on the grounds of the Iowa Sanitarium, one varies considerably from the others and from white oaks in general in character of leaves and fruit and in the color of the bark. The leaves are similar in shape to those of Quercus macrocorpa Michx, but are more downy beneath, resembling the leaves of Quercus bicolor, Wild, in this respect. The trunk is a little darker than the other trees otherwise it is of the white oak type. The fruits are twice or more the size of typical white oak fruits. They approach the …


Some Factors In Radiosensitivity, T. C. Evans Jan 1934

Some Factors In Radiosensitivity, T. C. Evans

Proceedings of the Iowa Academy of Science

The respiration and visible development of Mud Wasp larvae and of Grasshopper eggs have been followed after X-irradiation. It has been found that light doses of X-ray caused temporary alterations and heavy doses caused permanent suppression after some development had taken place. It has also been found that inactivity during and following the irradiation increased the resistance to the X-radiation.


The Hampton Tusk [Manuscript], Emmett J. Cable Jan 1934

The Hampton Tusk [Manuscript], Emmett J. Cable

Mastodon Tusk Background Material

On September 23, 1933, there was unearthed a large tusk in a gravel pit on the farm of W. S. Heuermann, section 21, Reeve township, Franklin County, about four miles south of the town of Hampton, Iowa. While loading gravel, one of the workmen, Lars C. Jensen, noticed something sticking out of the gravels that resembled a horn. Upon closer examination it was found to be a giant tusk, the largest of its kind, according to the best information available, ever found. The tusk was complete before it was broken by the workmen. The length was 11 feet, 7½ inches, …

The Heat Capacity And The Free Energy Formation Of Naphthalene, J. N. Pearce, W. B. Tanner

Proceedings of the Iowa Academy of Science

Because of work in project it became necessary to determine the heat capacity of compounds and solutions at low temperatures. To test the apparatus and method we have determined the heat capacity of napthalene at temperatures from liquid air to 25°.


A Pre-Wisconsin Valley In Southwestern Hancock County, L. W. Wood Jan 1934

A Pre-Wisconsin Valley In Southwestern Hancock County, L. W. Wood

Proceedings of the Iowa Academy of Science

An extensive road surfacing program in all the counties of northern Iowa for the past ten years or more has resulted in a severe drain on the gravel supplies of that territory, and has, in many cases, necessitated the search for new deposits. Such is the case in Hancock County. The kame and esker deposits, which were the first to be opened and worked, are now almost entirely exhausted, and gravels of the valley trains, though not so easily found, and though, in many cases, lying below the ground water level, hold the most promise for future needs. The valley …


A Twenty Years Phenological Record Of The Spring Flowering Plants Of Henry County, Ellsworth Dodds, H. E. Jaques Jan 1934

A Twenty Years Phenological Record Of The Spring Flowering Plants Of Henry County, Ellsworth Dodds, H. E. Jaques

Proceedings of the Iowa Academy of Science

Each spring since 1915 a record of the date of the first appearance of flowers of our seed bearing plants has been kept. This has been handled through a contest with the students in the botany classes. Reports on the comparative dates for some of the more representative species were made in 1918 and in 1924.

Change In Resistance Of Bismuth Single Crystals At The Melting Point, J. Henry Schroeder Jan 1934

Change In Resistance Of Bismuth Single Crystals At The Melting Point, J. Henry Schroeder

Proceedings of the Iowa Academy of Science

The resistances of seven single crystals of bismuth of various orientation, were measured as the temperature gradually increased to a few degrees beyond the melting point. It was found that the change from solid to liquid did not occur suddenly when the melting temperature was reached, but began at a temperature about two degrees below and continued to a temperature about one and one-half degrees above the melting point. As an explanation it is supposed that bismuth undergoes a change in crystal structure near the melting point and that this crystal structure persists in the liquid bismuth.


Course Content And Objectives, Reuel H. Sylvester Jan 1934

Course Content And Objectives, Reuel H. Sylvester

Proceedings of the Iowa Academy of Science

Comparisons of facts and principles taught in introductory courses in psychology in various colleges, reveal wide differences and extremes. Comparisons of various text books for such courses reveal a wide variety of subject matter. Students who complete introductory psychology in one school, might take a corresponding course in another with very little duplication. We lack standards and objectives.

The Effect Of Low Temperature On The Germination And Survival Of Native Oaks, J. M. Aikman Jan 1934

The Effect Of Low Temperature On The Germination And Survival Of Native Oaks, J. M. Aikman

Proceedings of the Iowa Academy of Science

Studies in the distribution of the native trees and shrubs of the prairie region of Iowa and eastern Nebraska have yielded data pertaining to oak species which are difficult to interpret without further research directed at the determination of the response of each plant to single environmental conditions. Studies of the response of the acorns and seedlings of the four species to temperature, soil moisture and light are being made. In this paper are presented data on the response of the acorns and seedlings to low temperature.


The Distribution And Life History Of Trillium Nivale Riddell, J. N. Martin Jan 1934

The Distribution And Life History Of Trillium Nivale Riddell, J. N. Martin

Proceedings of the Iowa Academy of Science

The snow trillium, the earliest spring flower in the woods of Iowa, is confined in its range almost entirely to the North Central States. It propagates mainly by seed but occasionally by the branching of the corn. At the Ledges State Park records show that the first flowers appear usually between the 10th and 25th of March. The seeds are mature early in June and the plants then die and disappear until the following spring. The seeds do not germinate until one or more winters have passed. The plant the first year is very delicate and consists of a corm, …


A Case Of Art Ability Following Sight Recovery In Seven-Year-Old Child Blind From Birth, Norman C. Meier Jan 1934

A Case Of Art Ability Following Sight Recovery In Seven-Year-Old Child Blind From Birth, Norman C. Meier

Proceedings of the Iowa Academy of Science

This study reports an investigation of a case of art ability in a child blind from birth until two months before the first picture was produced last December. The defective vision was caused by congenitally imperfect visual apparatus including nystagmus and complete double cataract. The latter was subjected to a series of operations mostly of the needling type with the expectation that the fluids would clear up the cataract substance. Not finding any reaction of this type developing, the surgeon resorted to the expedient of removing both natural lenses, thereby giving the subject a fair degree of vision through the …


Some Chemical Properties Of Vitamin E, H. S. Olcott Jan 1934

Some Chemical Properties Of Vitamin E, H. S. Olcott

Proceedings of the Iowa Academy of Science

In continuation of work toward the isolation and identification of vitamin E,1 the following observations have been made. The inactive product obtained by mild bromination of vitamin E concentrates can be reactivated by boiling with Zn dust and HCl in methanol solution. Vitamin E was not destroyed by the catalytic hydrogenation of concentrates at 200° and 200 atmospheres pressure, but the concentrates, after such treatment, were still unsaturated, as indicated by iodine number determinations. An active concentrate of vitamin E has been prepared from crude cottonseed oil.


Some Similarities Of Nuclear Organization In The Basidium And The Animal Spermatocyte, J. E. Sass Jan 1934

Some Similarities Of Nuclear Organization In The Basidium And The Animal Spermatocyte, J. E. Sass

Proceedings of the Iowa Academy of Science

After the fusion of the dikaryon in the basidium of Coprinus sterquilinus the fusion nucleus undergoes considerable enlargement. Associated with the nucleus there is a large "nebenkern." The latter body consists of a hyaline matrix containing a variable number of saucer shaped chromophilic platelets. As the fusion nucleus advances into the meiotic prophase, the nebenkern expands, the platelets scatter in an irregular manner into the cytoplasm, and apparently increase in number. The material of the nebenkern moves down toward the base of the basidium, and does not seem to be intimately associated with the subsequent meiotic processes of the nucleus.


Extent Of Patrician Glaciation, Charles Keyes Jan 1934

Extent Of Patrician Glaciation, Charles Keyes

Proceedings of the Iowa Academy of Science

There is one glaciation that did not reach Iowa, the absence of which throws all into confusion. This is the short glacier which reached southward only so far as St. Paul, Minnesota, from the Patrician center of ice dispersion. Because of not taking it into account, and another interval quite as long, Professor Calvin was always nonplussed concerning his Iowan loess being so enormously developed. Calvin's idea being that the loess was a glacial outwash could find no satisfactory explanation. But upon the theory of its being a wind deposit all these difficulties were at once removed, since the time …


Hyperfine Structure And The Depolarization Of Resonance Radiation By A Magnetic Field, A. Ellett Jan 1934

Hyperfine Structure And The Depolarization Of Resonance Radiation By A Magnetic Field, A. Ellett

Proceedings of the Iowa Academy of Science

The depolarization of Sodium D line resonance radiation resulting from the Larmor precession of the excited atoms has been carefully determined by a photographic method. Results are compared with a former visual determination (Jour. Opt. Soc. 10, 427, 1925). The effect of hyperfine structure and especially of the degeneracy due to the finite breadth of adjacent hyperfine levels is discussed following Breit, Rev. Mod. Phys. 5: 91, 1933, especially Section 4, p. 117 ff.


An Effect Of Cathode Rays On Photographic Paper, P. H. Carr Jan 1934

An Effect Of Cathode Rays On Photographic Paper, P. H. Carr

Proceedings of the Iowa Academy of Science

When photographic printing out or developing out paper is exposed to cathode rays in air (Lenard rays) for a sufficient time, it undergoes a color change similar to but not quite like that produced by exposure to light. It has been noted that, when a sample of the photographic paper is exposed to Cathode rays, it is rendered relatively insensitive to subsequent exposure to light. This peculiar effect is not observed when developing agents are used on the developing out paper, nor is it observed on blue print paper. Investigation indicates that the desensitizing effect of the cathode ray exposure …


Stomatal Count Of A Single Leaf Of Colocasia, John A. Yarbrough Jan 1934

Stomatal Count Of A Single Leaf Of Colocasia, John A. Yarbrough

Proceedings of the Iowa Academy of Science

In August 1933 the writer observed.an unusually vigorous specimen of Colocasia antiquorum, var. esculenta (known commonly as elephant's ear or caladium) growing in a yard in Falmouth, Kentucky which is located in the northern portion of that state. At the close of each growing season the tuber is taken up by the owner and placed in his cellar. The original tuber is about twenty years old and has of course given rise to many small tubers in addition to its twenty or more crops of huge leaves.


Is There A Deficiency Of Available Potassium In So-Called Alkali Soils Of Iowa?, Hartzell C. Dean Jan 1934

Is There A Deficiency Of Available Potassium In So-Called Alkali Soils Of Iowa?, Hartzell C. Dean

Proceedings of the Iowa Academy of Science

A review of the literature reveals conflicting opinions regarding the effects of lime upon the liberation of potassium in soils. The early investigators and most textbooks on soils adhere to the viewpoint that the addition of lime to soils results in the liberation of potassium through chemical reaction. It is believed by some that addition of calcium to soil materially affects the solubility of the potassium from the soil, so much so as to be of considerable practical value under field conditions. According to Jenny, as early as 1847 Liebig pointed out that the addition of lime furnished an invaluable …
