A Self-Survey Of The Iowa State Teachers College, Iowa State Teachers College

History of Education Book Gallery

The Self-Survey Report of Iowa State Teachers College which is presented in these pages is the work of about one hundred members of the faculty whose names appear on a separate sheet. Because the completed reports of the various committees were in some instances longer than seemed necessary, some condensations and omissions were suggested by Dr. Leo Goggin, who read the entire manuscript before it was mimeographed, and by the undersigned. It is hoped that the making of these changes has not resulted in the omission of material which should have been included or in distortion of the report of …

Toxic Algae In Iowa Lakes, Earl T. Rose

Proceedings of the Iowa Academy of Science

Almost all of the natural lakes of Iowa develop at certain periods throughout the summer and fall months, heavy growths of small floating plant life commonly known as blue-green algae. These tiny, primitive organisms develop rapidly in certain lakes, and often form unsightly, paint-like scums over calm lake surfaces, and particularly along lee shores. Upon decomposition of these heavy scums, or "bloom" as they are commonly termed, terrifically foul, pig-pen odors issue therefrom, making human living conditions in the vicinity intolerable, and limiting to a large degree all aquatic recreation. In addition to these unwholesome attributes, certain species of blue-green …

Analysis Of Lithium, James D. Resnick, Robert W. Kiser, J. Lester Dalton

Proceedings of the Iowa Academy of Science

The technology of lithium and its compounds was accorded little consideration a few years ago. Immediately following World War II fundamental knowledge of lithium began to be greatly expanded and its importance in industry has risen. Lithium and its compounds are used in porcelain enamels, and glazes; in air conditioning units; in greases, cosmetics and the like, just to cite a few examples. Lithium is the lightest of all the metals having an atomic weight of 6.94. The lithium ion has the smallest ionic radius of the alkalies and is approximately the same size as the magnesium ion. Its chemical …

Notes On The Occurrence Of Birds During The Spring Periods Of 1948-1950, In Northern Emmet County, Iowa, Henry G. Weston Jr.

Proceedings of the Iowa Academy of Science

Bird students are usually only vaguely aware of the orderly sequence of arrival dates of migrants and summer-residents in a given area. They know merely that certain species may be expected to appear at certain times each year. If data are compiled and presented in either tabular or graphical form, it becomes possible to evaluate year-to-year differences within one species and to make comparison between species. During the winter-spring-summer periods of 1947-1948, 1948-1949 and 1949-1950, the author gathered data on the occurrence of birds in northern Emmet County, Iowa. Although data were gathered from February through July of 1948 and …

A Thermosetting Resin For More Permanent Preservation Of Botanical Specimens, John R. Weber

Proceedings of the Iowa Academy of Science

The literature concerning the preparation of fresh and dried plant material for embedding in methacrylate resins is vuluminous. The excellent reviews of Fessenden and Fessenden and Sando adequately cover the work (3, 4). More recently, however, methods for the preservation of the natural pigments in plant material have been outlined (7).

Some Factors Affecting The Vitamin B12-Binding Properties Of Hog Mucosal Extracts, E S. Van Der Zant, L. A. Underkofler

Proceedings of the Iowa Academy of Science

Extracts of hog gastric mucosa (Ventriculin) contain a substance, probably protein in nature, which inhibits the growth promoting activity of vitamin B₁₂ for Lactobacillus leichmannii. Several investigators have claimed that heating destroyed the vitamin B₁₂ binding factor. Ternberg and Eakin (7), Shaw (5), and Burkholder (2) heated extracts of hog gastric mucosa to release vitamin B₁₂ in order to make it available to bacteria. Shaw (5) and Spray (6) reported that not all of the vitamin B₁₂ was released by heating. Gregory, Ford and Kon (3), however, found a vitamin B₁₂-binding substance in …

Rate Of Meander Development As Exhibited By Two Streams In Story County, Iowa, Keith M. Hussey, H. L. Zimmerman

Proceedings of the Iowa Academy of Science

During the winter of 1950 Mr. Zimmerman undertook the study of the drainage of western Story County. His first concern was that of an adequate base-map. This problem he solved by tracing the drainage from air photos of the area involved in the study. It was during this phase of the research that we discovered the full-scale working-model of some of the very experiments conducted by the Army Engineers at Vicksburg, Mississippi. The experiments were in effect detailed studies of the causation of meandering in rivers. Scale models of various situations were carefully constructed, then tested and the results noted …

A Group Level Of Aspiration Technique As A Measure Of Personality Rigidity, Seymour L. Zelen, Eugene E. Levitt

Proceedings of the Iowa Academy of Science

The problem of "personality rigidity" or the persistence of maladaptive behavior is becoming increasingly important in our culture. As part of a series of studies of the Preventive Psychiatry Project of the Iowa Child Welfare Research Station concerning this variable, it was decided to develop a group level of aspiration technique which would provide an operational measure of this concept. Inherent in such a technique is the opportunity for the subject to make numerous shifts of his goal level. The capacity to change goals in the light of new experience is an integral aspect of flexibility, and conversely an inability …

Variations In Two Spring Indices Of Male Pheasant Populations, Story County, Lowa, Eugene D. Klonglan, Edward L. Kozicky

Proceedings of the Iowa Academy of Science

The need for rapid indices to determine the spring population trends of ring-necked pheasants, Phasianus colchicus, on a statewide basis has resulted in the development of the crowing count (Kimball, 1949) and a male roadside count (Kozicky, 1952). Preliminary evidence (Kozicky, 1952) showed evidence that there was a higher degree of variation in areas of low population as compared to areas of high population (50 or more birds per section). Therefore, the intention of this study was to analyze the inherent variations in these two methods on secondary pheasant range in Iowa and compare them to findings in Winnebago …

A Report On A Survey Of Science Instruction In The High Schools Of Iowa, James W. Kercheval

Proceedings of the Iowa Academy of Science

This is a report of a survey pertaining to some phases of the science program in the junior and senior high schools of Iowa. The data on which this report is based was gathered by a questionnaire which was sent to each high school in the state. All data unless otherwise indicated applies to the school year of 1951-52.

Seed Retention Of Some Prairie Plants, A. L. Bakke, E. P. Sylwester

Proceedings of the Iowa Academy of Science

There are still a number of native prairie areas in Iowa. One of these outstanding tracts belongs to the Steel family of Cherokee, Iowa. It consists of about half a section located in Cedar Township in Cherokee county (N. 1/2 Sec. 16) one and a half miles northwest of the town of Larabee. The area has never been plowed: as a matter of fact, it has never been fenced. The flora of this area, like most of the other generally treeless areas of the state consist largely of perennial plants of a distinctly xerophytic type (1.3.4.5). The Graminae are the …

Relationships Of Temperature, Time And Moisture Content To The Viability Of Seeds Of Kentucky Bluegrass, Louis N. Bass

Proceedings of the Iowa Academy of Science

Kentucky bluegrass seed is usually harvested at quite high moisture levels. The freshly harvested material is packed in burlap bags where it may remain a few minutes, a few hours, or a day or two. While in the bags, the green material may also be piled up or loaded on trucks for long hauls. The seedsmen who handle bluegrass seed have known for a long time that green seed will heat while in the bags, especially when the bags sit for a long time, but they did not know how long the green seed could be left in the bags …

Aquatic Monocotyledons Of Iowa, Ernest O. Beal

Proceedings of the Iowa Academy of Science

During 1951 and 1952 a study of 116 species of aquatic monocotyledons was made, primarily from specimens in the herbaria of Iowa State College and the State University of Iowa. The selection of aquatic species was based, for the most part, upon those listed by Muenscher (1944) and from data on herbarium specimens as well as from limited personal field experience. Of the 14 families included, the Gramineae, with 17 species distributed in 11 genera, and the Cyperaceae, with 34 species in 7 genera are the best represented. Potamogeton, with 18 species is the largest of the 42 genera …

Primeval Forest Types In Lowa, William A. Dick-Peddie

Proceedings of the Iowa Academy of Science

The vegetation in Iowa has changed greatly since the advent of the settled. The prairie in Iowa has been virtually destroyed and there has been an advance of forest in all parts of Iowa (6). This study was made in order that a clearer understanding might be obtained of the primeval forest complex and its relation to prairie. Prairie made up about eighty-five per cent of the total vegetation in Iowa at the time of settlement (4). The forested area was completely cleared, hence, a study of the original forest as a link to yesterday is exceedingly difficult. It is …

Effects Of Ammonium And Nitrate Nutrition On Floral Initiation Of Tomato Plants, John Hacskaylo

Proceedings of the Iowa Academy of Science

There has been extensive work on the relationship of temperature, photoperiod and nitrogen supply to the time required to bring a plant from the vegetative to the reproductive phase. This investigation was designed to ascertain whether any differences existed between the time required for the initiation of the first floral primordia in tomato plants when treated with a nutrient solution containing all available nitrogen in the ammoniacal form as compared to a nutrient solution where all available nitrogen was in the nitrate form.

Boron In Relation To Water Balance In Plants, Genevieve Lukman Leaf

Proceedings of the Iowa Academy of Science

Several recent investigators have suggested that boron may affect the water balance of plants (22). Schmucker (16) stated that the main role of boron is to control the structure of the protoplasm. The data of Dennis (6) indicated that boron regulates the water relations of the plasma colloids. Schropp and Arenz (17) found that boron prevented unusual swelling of the plasma colloids which would interfere with the ascent of water in the stem. Reports by Bobko (2) indicate that wilting of cotton was decreased with the application of boron and related date by Willis and Piland (21) for Romaine lettuce …

Diurnal Changes In Sap Acidity Of Certain Plants, Helen C. Loehwing

Proceedings of the Iowa Academy of Science

The earliest published record of diurnal changes in sap acidity appears to be the report of Heyne (8) in 1813 who detected it by the sense of taste. He found that Bryophyllum calycinum was more sour early in the morning than in late afternoon. According to Richards (19), these observations were corroborated by Link who tested the juice from the same species and other crassulaceous forms with litmus paper. Other investigators also verified these observations and various explanations were offered for such diurnal changes in acidity (6, 21). Succulents were used in most of the early investigations on diurnal changes …

The North Central Helicosporae, Royall T. Moore

Proceedings of the Iowa Academy of Science

The Helicosporae are members of the form-order Moniales and encompass all those fungi that bear conidia coiled spirally in two or three dimensions. With the exception of the genera Helicoceras (3) and Drepanoconis (2) (not represented in this area), they are saprobic. These saprobic members form colonies that range from extensive, loose, arachnoid mats to small pulvinate masses scattered over the substrate. Twenty-six species distributed through seven genera are recognized as occurring in the north central United States.

A Resurvey Of The Violets Of Iowa, Norman H. Russell

Proceedings of the Iowa Academy of Science

The following account must be considered preliminary in the sense that it is based primarily upon herbarium research. During the summer months of 1952, the writer was employed as an instructor by the State University of Iowa and, while there, engaged in a study of the violets, using material from the Herbaria of the State University of Iowa, Iowa State College, and Grinnell College. Appreciation is expressed to these institutions for the use of their specimens. In addition, many thanks are due Dr. Robert T. Thorne and Dr. Robert L. Hulbary for their cooperation and helpfulness during the period of …

The Concentration Of Forest Tree Roots In The Surface Zone Of Some Piedmont Soils, Wayne H. Scholtes

Proceedings of the Iowa Academy of Science

The location and amount of small roots m a forest soil are of interest, because the small roots afford an approximation of the water absorbing surfaces of trees. Small roots occur profusely in branches and mats from the main lateral roots and tend to concentrate in the upper soil horizons. Referred to as "Feeding" roots by many, small roots are the means of moisture and nutrient intake from the soil. It is of interest to evaluate the effect of soil properties upon the presence of small roots. The physical properties of the soil may possibly limit root growth through their …

Notes On Rare Iowa Plants, Robert F. Thorne

Proceedings of the Iowa Academy of Science

Three years of field work in Iowa (1950-1952) have turned up many vascular plants that have been unreported previously from Iowa, that have not been collected in many years, or that have been generally considered rare in the state. For the information of botanists who might be interested in them, these collections are listed here in Englerian sequence with pertinent comments. Included with them are a few noteworthy species represented by old herbarium specimens that had been misidentified or otherwise overlooked heretofore. For some of the included species associated plants have been listed as being the best indicators of the …

The Relationship Of Photoperiod To Growth And Flowering Of Melilotus Species, Samuel C. Wiggans

Proceedings of the Iowa Academy of Science

Sweetclover is used extensively in Iowa as a soil-improving crop and forage legume. The two species utilized are Melilotus officinalis, the yellow-flowered type, and M. alba, the white-flowered type. Although both annual and biennial forms of M. alba are available, the biennial form is grown more extensively. Only biennial forms of M. officinalis are grown. Since Garner and Allard (1920) first demonstrated that relative length of day was an important factor in the sexual reproduction of plants, numerous studies have been conducted on the effect of photoperiod on plant growth. Extensive literature reviews have been published by Murneek and …

Preparation And Some Properties Of Manganese (Ii) Chlorate, F. E. Brown, J. D. Woods

Proceedings of the Iowa Academy of Science

In the course of a study on the action of manganese on the decomposition of chlorates, it becomes desirable to know some of the properties of manganese chlorate. A search of the literature showed that the preparation of manganese chlorate in solution was reported as early as 1843 (1), and that even in dilute solution this compound is unstable. Manganese chlorate, itself, however, has not been described.

Some Aspects Of The Chemistry Of Samarium (Ii) Compounds, Alexander I. Popov, Wesley W. Wendlandt

Proceedings of the Iowa Academy of Science

Although the normal oxidation state of the rare earth elements is the tripositive one, several of them are capable of exhibiting either a lower or a higher valence of variable degrees of stability. Of particular interest in this investigation was the divalent state exhibited by samarium. It is well known that half-filled electronic shells tend to be rather stable. Divalent europium with electronic configuration of Xe 4f⁷* forms quite stable compounds which are slowly oxidized by water. Another stable rare earth divalent ion is Yb++ where the 4f shell is complete, (Xe 4f¹⁴), divalent samarium ion, …

The Replacement Of Aromatic Hydroxyl By Chlorine, Walter T. Smith Jr., Louis Campanaro

Proceedings of the Iowa Academy of Science

Some phenols, particularly those activated by nitro-, carboxyl, or other meta-directing groups in the ortho or para positions are known to react with phosphorus pentachloride with replacement of the phenolic hydroxyl by chlorine. This transformation has also been accomplished in some cases by treating the phenol with p-toluenesulfonyl chloride in the presence of a tertiary amine such as N,N-dimethylaniline. A notable example of the latter reaction is the conversion of 2,4-dinitro-naphthol to 2,4-dinitro-1-chloronaphthalene (1). We have studied the replacement of phenolic hydroxyl by chlorine in several different cases. Our results suggest that the nature of the reaction may be …
