The Potential Of The Silver-Silver Iodata Electrode At 25°, J. N. Pearce, Verda I. Wirth
The Potential Of The Silver-Silver Iodata Electrode At 25°, J. N. Pearce, Verda I. Wirth
Proceedings of the Iowa Academy of Science
The electromotive force of a series of cells of the type: Hg, Hg2Cl2, KCl(m), KIO3 (m), AglO3, Ag, have been measured at 25°. By combination of these potentials with the potentials of the corresponding calomel electrodes, they find the most probable potential of the Ag, AgIO3 , IO3-(α = 1) electrode to be Eo 298 = 0.3569 volt.
The Kansas City Formation In The Devil's Backbone Region, Madison County, Arthur Goshorn
The Kansas City Formation In The Devil's Backbone Region, Madison County, Arthur Goshorn
Proceedings of the Iowa Academy of Science
Two beds of limestone, each 12-13 feet thick, above the DeKalb, are exposed in Gordon's Hollow, one mile north of the tunnel through the Devil's Backbone in Pammel Park. South of the tunnel about a mile, a heel of limestone 12-13 feet thick, above the DeKalb, is exposed at intervals close to the top of the bluff. Exact correlation of these beds may show that all members of the Kansas City are present in the Backbone region.
Substitution Of Time For Stress In Performance Of Measure Accent In Piano Music, Mack T. Henderson
Substitution Of Time For Stress In Performance Of Measure Accent In Piano Music, Mack T. Henderson
Proceedings of the Iowa Academy of Science
Very definite time organizations occur within the measure of a given musical selection (3/4 time) apparently for the purpose of measure accent. Successive changes in stress do not account for measure accent nor do they operate with time changes to enhance the accent. Measurements are based upon recordings on the Iowa Piano Camera of the chorale section of Chopin's Nocturne, No. 6 (Opus 15, No. 3).
Reinfection Of Rats With Eimeria Miyairii After Immunization, E. R. Becker, Phoebe R. Hall
Reinfection Of Rats With Eimeria Miyairii After Immunization, E. R. Becker, Phoebe R. Hall
Proceedings of the Iowa Academy of Science
It was shown in previous paper (1932) that rats which had not previously been infected became immune to Einzcria. miya.irii after recovery from an infection produced by ingesting 1500 oocysts daily for five days. It was also stated that in the passing of the weeks some of the immunity was lost. The latter statement was based upon an experiment with four rats which showed the last coccidia on September 25, 1931, and which could not be reinfected immediately, but which again became infected after ingesting large numbers of oocysts on December 12, 1931, - about 78 days after the last …

Some Biological Contributions To Recreation (Address Of The President), H. E. Jaques
Some Biological Contributions To Recreation (Address Of The President), H. E. Jaques
Proceedings of the Iowa Academy of Science
To my memory comes the scene of a little group of college students nearing the end of a long morning tramp through the tall dew wet grass of early spring. We were out on a bird trip and had gone several miles through the woods. The physical condition of the little company would not be expected to inspire enthusiasm. As we reached the city park and found still more warblers breakfast gathering in the trees, one of the young women cried out with an exultation never to be forgotten, "Oh! I know I shall enjoy this all my life."
A Preliminary Study Of Some Herbicides On Dandelions, L. E. Arnold
A Preliminary Study Of Some Herbicides On Dandelions, L. E. Arnold
Proceedings of the Iowa Academy of Science
The dandelion (Taraxacum officinale Weber) is one of the most common and persistent weeds in lawns and one for which no effective and practical method of eradication has been devised. Cutting the plants below the surface of the soil is effective if repeated frequently, but few individuals consider this method practical. Sprays such as iron sulfate which are supposed to have a differential action on dandelions and grasses leave much to be desired, while stimulating the grasses in an attempt to crowd out the dandelions has met with only moderate success. This situation led to a search for an effective …
The Effects Of Exfloration On The Soybean, Stanley Austin
The Effects Of Exfloration On The Soybean, Stanley Austin
Proceedings of the Iowa Academy of Science
Most of the literature on growth and reproduction in plants leaves the implication that cessation of vegetative activity in plants of an indeterminate type of growth is due to the drain of nutrient materials imposed on the plant by the developing fruits. This is not true for the soybean. The variety used in this investigation flowers early and continues to grow for some time afterward and appears to cease growing as the fruits mature. However, plants from which the flowers are continuously removed increase in percentage of dry weight at the same rate as the controls and stop growing at …
The Somatic Chromosomes Of Cypripedium Hirsutum And Six Species Of Habenaria, L. M. Humphrey
The Somatic Chromosomes Of Cypripedium Hirsutum And Six Species Of Habenaria, L. M. Humphrey
Proceedings of the Iowa Academy of Science
The chromosome numbers of eight species of the Orchidaceae were reported last year. The purpose of this paper is to report seven more species. The material was collected in Minnesota and Massachusetts. The following numbers were found: Cypripedium hirsutum, 2n = 20; Habenaria blephariglottis, 2n = 42; H. clavellata, 2n = 42; H. dilatata, 2n = 42; H. Hookeri, 2n = 42; H. hyperborea, 2n = 42; and H. obtusata, 2n = 42. The size relationships are the same as in the species studied last year. The Cypripedium has very large chromosomes, and the Habenarias relatively very small ones.
Oxygen Absorption And Carbon Dioxide Production In Soils, F. B. Smith, P. E. Brown
Oxygen Absorption And Carbon Dioxide Production In Soils, F. B. Smith, P. E. Brown
Proceedings of the Iowa Academy of Science
Carbon dioxide production in the soil has long been regarded as a measure of biological activity. It has been suggested that oxygen absorption might give a more reliable measure of the total action of microorganisms than carbon dioxide production. Since the amount of oxygen consumed by aerobic organisms under constant environmental conditions bears a definite relation to the amount of carbon dioxide produced, it would seem that the ratio of carbon dioxide produced to oxygen consumed would show something concerning the nature of the organic matter of the soil, its composition and rate of decomposition and, therefore, be a better …
Conidial Production In The Genus Cercospora, C. M. Nagel
Conidial Production In The Genus Cercospora, C. M. Nagel
Proceedings of the Iowa Academy of Science
One of the limiting factors in the study of the biology of several species of the genus Cercospora has been the failure of investigators to obtain conidia abundantly and at will in pure culture.
Perennial Sow Thistle (Sonchus Arvensis L.) In Iowa, Ada Hayden
Perennial Sow Thistle (Sonchus Arvensis L.) In Iowa, Ada Hayden
Proceedings of the Iowa Academy of Science
Perennial sow thistle (Sonchus arvensis L.) has wide geographical distribution. It occurs throughout Europe to 70° 35' North, in Siberia, Caucausus and lower Asia to Afghanistan. It is naturalized in India, Ceylon, Japan, North Africa, Australia and New America. Perennial sow thistle thrives in cultivated and uncultivated ground and in a wide range of soils. Its seeds have a high percentage of germination, without requiring a rest period. The plant may be propagated from cuttings of the root less than half an inch long as well as from the short upright rootstocks. The flowers are perfect; in seven days after …

Sugar Dissimilation By Shigella Paradysenteriae Variety Sonne, Howard Reynolds, C. S. Mccleskey, C. H. Werkman
Sugar Dissimilation By Shigella Paradysenteriae Variety Sonne, Howard Reynolds, C. S. Mccleskey, C. H. Werkman
Proceedings of the Iowa Academy of Science
Colonies of Shigella paradysenteriae var. Sonne are characterized on lactose and sucrose agar media by the formation of papillae after several days' incubation at 37° C. Organisms in the papillae dissimilate lactose or sucrose with the formation of acid within 24 hours, whereas the remaining organisms in the colony fail to show acid production on china blue-rosolic acid differential medium. The acid papillae appear blue on a pink colony. In a liquid medium containing sucrose or lactose, alkaline organisms reach a maximum after two to six days followed by a decline of alkaline organisms with a marked increase of acid …
Germination Of Corn In The Field As Affected By Soil And Air Temperature, J. M. Aikman
Germination Of Corn In The Field As Affected By Soil And Air Temperature, J. M. Aikman
Proceedings of the Iowa Academy of Science
The corn was planted at weekly intervals from April 15 to May 27. A continuous record of soil and air temperature was obtained from a soil-air thermograph set up in the plot. Tabulations were made of maxima, minima and average weekly soil and air temperatures for the germination period of each planting. The length of the period necessary for 85 per cent emergence for the seven plantings was 21, 22, 18, 18, 16, 15 and 11 days respectively. Length of germination period shows a higher correlation with average soil temperature than with air temperature. Correlation with the total heat units …
Some Effects Of Fertilization On Nitrification In High-Lime Soils, F. B. Smith, Hartzell C. Dean
Some Effects Of Fertilization On Nitrification In High-Lime Soils, F. B. Smith, Hartzell C. Dean
Proceedings of the Iowa Academy of Science
Applications of potassium chloride at the rate of 100, 200 and 500 pounds per acre were made on two soils containing a high calcium content. Oat straw at the rate of 2 tons of dry matter per acre was applied alone and in combination with potassium chloride. Sweet clover at the rate of 2 tons of dry matter per acre was applied alone and in combination with potassium chloride. Samples of the soils were taken 4 weeks after treatment in the greenhouse and again after 5 months for nitrification determinations.
The Effect Of Lime And Phosphate On Nitrification In An Acid Soil, Harold L. Dean, F. B. Smith
The Effect Of Lime And Phosphate On Nitrification In An Acid Soil, Harold L. Dean, F. B. Smith
Proceedings of the Iowa Academy of Science
The nitrate content in all soils is maintained through the action of microorganisms upon ammonia. This process of nitrate production is called nitrification. It is interesting to note the effect that lime and rock phosphate has upon the nitrate producing power in an acid soil.

A Study Of The Boiling Point Elevation In Solutions Of Potassium Iodine In Ethyl Alcohol, J. N. Pearce, M. L. Mcdowell
A Study Of The Boiling Point Elevation In Solutions Of Potassium Iodine In Ethyl Alcohol, J. N. Pearce, M. L. Mcdowell
Proceedings of the Iowa Academy of Science
A study has been made of the elevation of the boiling point of ethyl alcohol by potassium iodide. A differential method has been employed and the temperature variations were measured by a sensitive thermoelement. The experimental boiling point elevation- molality curve has been found to follow very closely that of a normal undissociated solute, indicating only a slight degree of dissociation. From this data the activities and free energy relations are calculated.
The Effects Of Potash And Crop Residues On Available Potassium In Some Alkali Soils Of Iowa, Hartzell C. Dean, F. B. Smith
The Effects Of Potash And Crop Residues On Available Potassium In Some Alkali Soils Of Iowa, Hartzell C. Dean, F. B. Smith
Proceedings of the Iowa Academy of Science
Many investigators have found that high-lime soils may often be deficient in available potassium. According to the present theory, the low availability of the potassium in such soils is probably due to the high concentrations of calcium salts. The "so-called" alkali soils of Iowa have been found to contain high concentrations of both calcium carbonate and calcium bicarbonate. Apparently the concentrations of these salts are so high that they tend to depress the availability of the potassium in the soil.
A Modification Of Bettendorff's Arsenic Test And A Quantitative Determination From Small Concentrations Of Mercury, W. Bernard King, F. E. Brown
A Modification Of Bettendorff's Arsenic Test And A Quantitative Determination From Small Concentrations Of Mercury, W. Bernard King, F. E. Brown
Proceedings of the Iowa Academy of Science
The presence of mercuric chloride affects Bettendorff's test for arsenic. The addition of enough mercuric chloride to make its concentration 0.00001 M., before the addition of stannous chloride: (1) hastens the appearance of the coloration, (2) increases the sensitivity of Bettendorff's test ten-fold to one hundred fold and (3) enables the test to be made in a lower concentration of hydrochloric acid. Mercuric chloride in 0.00001 M. solutions does not produce turbidity when stannous chloride is added. In the presence of mercuric chloride Bettendorff's test will detect a smaller quantity of arsenic than Gutzeit's test or Marsh's test. The rate …
