The Root-System Distribution Patterns For Five Oat Varieties, R. Stucker, K. J. Frey

Proceedings of the Iowa Academy of Science

Dry weights of the root systems of 5 oat varieties were determined at 4-inch intervals to a maximum depth of 24 inches. The varieties produced a differential distribution of root dry weight at the various depths sampled. Over 60 percent of the root dry weights of the Corn Belt varieties, Clinton, Marion, and Andrew, was in the upper 4 inches of soil, whereas comparable values for Craigs-afterlea and A465 were 50 percent and 35 percent, respectively. The root dry weight to a depth of 24 inches was the same at the boot stage as at maturity.

Comparative Solubility Of Protein In Cottonseed Flakes Extracted By Hexane And By Ethanol At Two Different Temperatures, Lionel K. Arnold, R. Basu Roy Choudhury

Proceedings of the Iowa Academy of Science

The solubility in water, in 3 percent sodium chloride solution, and in 0.2 N sodium hydroxide solution of cottonseed flakes extracted by ethanol at 172° F. is lower than similar flakes extracted by hexane at 146° F. Data are presented which indicate the lower solubility is mainly the result of the differences in the solvents rather than the temperatures. The difference in solubility in the sodium hydroxide solution is less than in the sodium chloride solution.

Presidential Address - The Academy Of The State And The State Of The Academy, William C. Oelke

Proceedings of the Iowa Academy of Science

Our experimentation with the arrangement of the Academy program this year, largely due to the insight and initiative of Dr. Don Lewis of the State University of Iowa, and ably forwarded by Dr. Sherwood Tuttle and others from our host institution, seems to have been most successful if one can judge from the results so far. This rearrangement of the program, placing the address of the president in juxtaposition with the business meeting, allows and indeed makes advisable a change in its character.

The Development Of Ear Prirnordia Of Zea In Relation To Position On The Plant, John E. Sass

Proceedings of the Iowa Academy of Science

The development of auxiliary buds of a yellow dent maize hybrid was studied. Seven buds at acropetally successive nodes survived at least to 68 days after planting and became pistillate inflorescences, potential ears. Meiosis occurred in the basal ovaries of the upper two ears after 68 days, when the styles were 2 mm. long, and complete embryo sacs were present by 71 days. The two upper ears attained approximately the same morphological and cytological stage between 68 and 71 days. The top bud invariably became the harvestable ear. The failure of complete development of the second ear is not ascribed …

Recovery Of White And Gray Isolates Of Ceratocystis Fagacearum From Red Oaks, M. A. Marchetti

Proceedings of the Iowa Academy of Science

Boles of four Erythrobalanus oaks were inoculated with white and gray isolates of Ceratocystis fagacearum at diametrically opposed loci. Bole and branches were sampled in an orderly manner when a tree exhibited moderately severe foliar wilt symptoms. Isolations were made on PDA plates. Of the four red oaks, two yielded only the white isolate; the remaining two yielded both isolates. In no instance were both isolates recovered from the same branch, but all sections from the main trunk yielded both, and in several instances both isolates were observed growing from the same chip. This pilot experiment and the findings of …

Electrophoretic Studies Of The Proteins Of Plasma And Ascitic Fluid In Cirrhosis, J. I. Routh, W. D. Paul

Proceedings of the Iowa Academy of Science

A series of plasma and ascitic fluid specimens withdrawn from patients with cirrhosis, and a series from one patient over a seven-week period prior to his death, were subjected to electrophoretic analysis. The results indicate a qualitative similarity between plasma and ascitic fluid protein patterns. In most instances, the ascitic fluid contained more albumin, alpha1 and gamma globulins than the plasma, whereas the plasma was richer in alpha₂ and beta globulins and fibrinogen. Based on the molecular weights of the protein fractions, the values indicate that selective protein enrichment of ascitic fluid may be related to the molecular size …

Allyl Derivatives Of Sympathomimetic Amines, Ellen Fox, Elaine Lynch, Myna Theisen, M. Marguerite Christine

Proceedings of the Iowa Academy of Science

The allyl group was substituted on the side chains of benzedrine and ephedrine in the belief that these derivatives would antagonize the parent compounds. Their antagonistic effect was clearly demonstrated; the action was believed to be due to reaction at the receptors in the muscles.

Exchangeable Potassium And Clay Minerals In Selected Iowa Soil Profiles, J. J. Hanway, R. L. Handy, A. D. Scott

Proceedings of the Iowa Academy of Science

Exchangeable K values and X-ray diffraction patterns were obtained for soil samples from several modal profiles of nine different soil series in Iowa. Exchangeable K in "moist" subsoils was consistently low and almost always lower than in the "moist" surface soil. Drying increased exchangeable K in all the soils, but the increase due to drying varied between soil series and with depth in the profile of each series. Reversion of exchangeable K to a non-exchangeable form on rewetting the oven-dry samples generally increased with depth in the profile but the exchangeable K never decreased to the original "moist" level. X-ray …

Distribution Of Manganese In A Bio-Topo Sequence Of Southeastern Iowa Soils, E. C. A. Runge, L. De Leon

Proceedings of the Iowa Academy of Science

Manganese extractable by sodium hydrosulfite was determined for 9 soil profiles of a bio-topo (vegetation and drainage) sequence in southeastern Iowa. The distribution of manganese in the soils studied is influenced by vegetation, drainage, and pH. Under prairie vegetation the manganese is evenly distributed with depth in the well-drained soil, but with increasing wetness of the soil profile, manganese is apparently lost from the A1 horizon and accumulates in the lower part of the B horizon. Manganese accumulates in the A₁ and A₂ horizons of the well-drained soils developed under forest vegetation, but in profiles of increasing wetness …

The Reorientation Of Calcite Crystals In Limestone, Sharon Curry

Proceedings of the Iowa Academy of Science

Limestone from the Hampton Formation at Ferguson, Iowa, was studied in an effort to determine whether the vertical force of overburden had caused preferential orientation of crystals. Results are insufficient to indicate the extent of recrystallization caused by overburden; there is evidence that there has been horizontal influence also. Petrofabric diagrams are included.

Stratigraphic Studies Of The Gilmore City Formation At Rutland, Iowa, James K. Wagner

Proceedings of the Iowa Academy of Science

An interesting relationship between the beds of limestone and dolomite in a quarry and at outcrops along the Des Moines River near Rutland, Iowa, is described. In the quarry a composite of 11 feet of limestone-dolomite-limestone is exposed, whereas at an outcrop along the river 300 feet northeast the dolomite is absent and 12 feet of limestone is exposed. These beds of limestone and dolomite have been referred to the St. Louis formation uncomformably overlying Gilmore City limestone. The author proposes that the dolomite represents an area of late diagenetic alteration within the Gilmore City formation.

Some Notes On The Occurrence Of A Coal Seam In The Cedar Valley Formation Of Johnson County, Iowa, Verne E. Dow

Proceedings of the Iowa Academy of Science

Samples of carbonaceous material from several exposures of the Cedar Valley formation have been studied in order to establish a basis for calling the material a coal. Examination has shown that the material is a "cannel'' coal, and it is believed to be one of the earliest known coals in North America.

Estimate Of Slope Classes By Counties In Iowa, R. W. Arnold, L. E. Tyler, F. F. Riecken

Proceedings of the Iowa Academy of Science

The proportion of land in given slope classes has been estimated for Iowa counties from a randomly selected sample. The sample, approximately 2 percent of the land area of the state, consists of about 4,500 individual tracts, each about 160 acres in size. A detailed soil map was made of each tract, using a 4-inch-to-the-mile aerial photograph as a base map, thus providing the basic information for a physical land-condition inventory. The data from the soil maps were projected to give estimates of physical land conditions by counties and for the state as a whole. On a state basis, nearly …

Characteristics Of The Floyd And Some Related Soils In Floyd And Bremer Counties, Iowa, J. A. Phillips, F. F. Riecken

Proceedings of the Iowa Academy of Science

This study deals with imperfectly and poorly drained soils generally considered to have developed under prairie from a parent material consisting of a sandy-silt mantle overlying Iowan glacial loam till. Three Floyd profiles, two profiles of the proposed Tripoli series (Floyd, poorly drained variant), and one Clyde profile were studied in the field and in the laboratory. Results indicate that the Tripoli soils should be separated from the Floyd and mapped as a separate series. The present concepts of the Floyd series as a minimal Brunizem and the Tripoli as a minimal Wiesenboden are substantiated by field studies and laboratory …

Geological Age Of Soldier Creek Buffalo County, South Dakota, Alan H. Coogan

Proceedings of the Iowa Academy of Science

A quantitative analysis of data derived solely from maps of Soldier Creek and a comparison with similar data from Good Soldier Creek show Soldier Creek to be a composite stream of several branches which differ in drainage composition and which therefore probably differ in origin. A study of the field evidence bearing on anomalous factors in the quantitative analysis shows Soldier Creek was formed by the capture of several post-Iowan streams by a younger post-Cary stream.

A Revision Of A Completion Method For Inverting Matrices And Its Adaptation To Ill-Conditioned Matrices, William L. Waltmann

Proceedings of the Iowa Academy of Science

An essentially new method for the inversion of n x n matrices, closely related to the method of completion attributed to Sherman, Morrison, and Bartlett, is presented. This revised technique has the added advantages that it can be used for any square matrix, regardless of its conditioning state, and that it can be readily adapted to electronic digital computers.

A Theoretical Study Of A Randomly Excited Mechanical Oscillator, Victor W. Bolie, Francis M. Long

Proceedings of the Iowa Academy of Science

A mathematical investigation is made of the feasibility of extracting usable mechano-electric power from a critically damped and randomly excited mechanical oscillator. Two different analytic functions are used to approximate practical squared-velocity spectra for the motion of the vehicle supporting the oscillator, and the corresponding expressions for extractable power are developed. Numerically computed results are presented graphically to illustrate the effects of varying the oscillator parameters.

A Note On Dialectics In Mathematics, William A. Small

Proceedings of the Iowa Academy of Science

A complete dialectical process is defined; it is shown that such a process is a function, and that every real function is a complete dialectical process. Some general implications of this result are discussed.

Three Dimensional Pressure Temperature Entropy Diagram, Paul M. Boatman

Proceedings of the Iowa Academy of Science

Three properties of carbon dioxide, namely, pressure, temperature, and entropy, are combined to produce three graphical plots: (1) Pressure vs. Temperature, (2) Entropy vs. Temperature, and (3) Entropy vs. Pressure. These three plots are, in actuality, the three projections of a three-dimensional surface depicting all the phases of carbon dioxide. The fluid must exist on the surface at all times, and any thermodynamic process will occur along the surface. The general configuration of the three dimensional surface for carbon dioxide is shown, and the areas depicting structures are labeled.

The Effect Of Core Current On Magnetic Materials, John B. Dinklage

Proceedings of the Iowa Academy of Science

The effect on the hysteresis of sending a direct current through the core of a ferromagnetic torroid is described. A model describing this effect is then related to the magnetostrictive properties of the material. An easy method for determining the "polarity" of the magnetostrictive properties of a material is presented.

Correlates Of Achievement In A Veterinary Medicine Curriculum, Thomas E. Hannum

Proceedings of the Iowa Academy of Science

A correlational study was made of test scores and achievement of Veterinary Medicine students who graduated in the spring of 1959 from Iowa State University. Cumulative grade point averages were obtained at the time of graduation and correlated with selection data obtained at the time of admission to the College of Veterinary Medicine in the fall of 1955. These data included: pre-veterinary grade point averages; interest scores on the Strong Vocational Interest Blank; Veterinary Aptitude Test scores; American Council on Educational Psychological Examination (College Edition), Quantitative and Linguistic scores; and numerical ratings made by a faculty committee during screening interviews …

The Influence Of The Antithyroid Drug, Propylthiouracil, On Reproduction In Rats, Kenneth M. Cook

Proceedings of the Iowa Academy of Science

The antithyroid drug, propylthiouracil (PTU), when fed to white rats at the dietary level of 0.1 percent PTU in finely ground laboratory chow for ten weeks prior to mating, does not affect the ability of either male or female rats to reproduce. All metabolic evidences examined indicate a lower metabolism under the influence of PTU. The PTU dietary treatment was ceased at conception of PTU females. Characteristics of the offspring did not differ from those produced by mothers maintained on normal laboratory chow throughout the experiment.

Altered Growth Of Animals After Continual Centrifugation, Charles C. Wunder

Proceedings of the Iowa Academy of Science

Two different animals have demonstrated an accelerated growth after prolonged centrifugation. This report is primarily concerned with larvae of the common fruit fly, Drosophila melanogaster, after 24 hour periods of centrifugation at fields between 2200 and 3300 G's. Similar studies are reported for the laboratory white mouse, Mus musculus after seven days of centrifugation at 7 G's. The faster growth is possibly due to more efficient growth, resulting as an adaptation to greater gravity. Such a suggestion is supported by the finding that centrifuged larvae exhibit a reduced oxygen requirement for growth.

Some Aspects Of Quantitative Histology Of The Liver Of A-Jax Mice Before And During Tumor Induction With Carbon Tetrachloride, Paul A. Meglitsch, Robert R. Mote, Leland P. Johnson

Proceedings of the Iowa Academy of Science

The proportion of the cell populations composed of parenchymal, littoral, and other types of cells is reported for control mice, mice repeatedly anesthetized, mice fed with olive oil repeatedly, and mice fed with carbon tetrachloride and olive oil, showing that the cellular components undergo a marked change when carbon tetrachloride is administered. The proportion of the liver volume occupied by parenchymal cells is found to be relatively stable throughout the period of tumor induction. The nuclear-cytoplasmic ratio of parenchymal cells is found to fall with the aging of control mice and those fed olive oil or anesthetized during the period …

Report On A Retroperitoneal Teratoma (Foetus In Foetu), E. V. Enzmann, S. D. Miroyiannis, M. M. Magen

Proceedings of the Iowa Academy of Science

Successful removal of a retroperitoneal teratoma from an infant is described. Various theories dealing with the origin of such tumors are discussed. Blood supply, hemopoiesis and circulation of the tumor have been investigated.
