Presidential Address: Mathematical Combinations Which Correspond To Physical Impossibilities, E. R. Smith
Presidential Address: Mathematical Combinations Which Correspond To Physical Impossibilities, E. R. Smith
Proceedings of the Iowa Academy of Science
In speaking to you as a representative from the Mathematical Section of the Academy, I have a feeling of hesitance which is quite usual among mathematicians when they address a mixed or non-mathematical group of scientific men and women. It is a well established tradition that scientists may complacently separate themselves from mathematics and it is equally true that mathematicians are timid about discussing their work with scientists outside their own circle. On the one hand the scientist tends to avoid abstraction, and on the other hand the mathematician does not seek reality. It was this feeling of Separation that …
The Iowa Academy Of Science In Relation To Its Contributions To The Welfare Of The Commonwealth Of The State And Nation, J. N. Martin
The Iowa Academy Of Science In Relation To Its Contributions To The Welfare Of The Commonwealth Of The State And Nation, J. N. Martin
Proceedings of the Iowa Academy of Science
State Academies have seemingly had their greatest success in the Central-Western states. In these states the more isolated conditions of the scientific workers made the need for such organizations keenly felt. But, important as the academies have been in broadening and shaping the scientific views and attitudes of their members and in stimulating the scientific endeavors of its members and others within the scope of their influence, they quite early in their history took on another function of great importance. They soon began to serve in advisory capacities on various scientific problems concerning the welfare of the state and even …
The Survey Courses In Science, C. W. Lantz
The Survey Courses In Science, C. W. Lantz
Proceedings of the Iowa Academy of Science
What should be the nature of the beginning courses in science in our colleges? There has been much criticism directed at these courses. The criticism is usually to the effect that they are too technical and are planned to meet the needs of those who are going to be specialists in some field of science whereas relatively few will continue in a particular field of science. The courses are said to be unrelated to everyday life, whereas what is needed are courses that will give an understanding and an appreciation of modern science as it applies to everyday life in …

Use Of A Constant-Temperature Water Bath As A Culture Chamber, James H. Craft
Use Of A Constant-Temperature Water Bath As A Culture Chamber, James H. Craft
Proceedings of the Iowa Academy of Science
In the course of experiments done at the State University of Iowa on excised leaves of Bryophyllum calycinum a need arose for a culture chamber in which light, temperature, and humidity could be controlled simultaneously. The chamber described below met these requirements. It is capable of providing a wide range of environments which should make it useful in the culture of bacteria or other microorganisms and it might be substituted for equipment currently unobtainable. Dimensions given here may be modified as necessary.
Ultra-Violet Irradiation Of Spores Of Certain Molds Collected From Bread, D. B. Conklin
Ultra-Violet Irradiation Of Spores Of Certain Molds Collected From Bread, D. B. Conklin
Proceedings of the Iowa Academy of Science
Since the discovery of the anti-biotic effects of the blue-violet end of the spectrum, (Ward, 1894) this light has been widely applied to practical advantage. The bactericidal properties of these rays have been extensively utilized in the sterilization of air. Fulton (1929), Welch (1930), Luyet (1932), Duggar and Dimond (1940), and others, have shown the deleterious effect of ultra-violet light on certain fungal spores. Problems of food spoilage due to contamination with common molds have recently become more significant than heretofore. Spoilage of bakery products has become especially serious due to delays in deliveries and prolonged storage occasioned by curtailment …
Illustrations Of The Fleshy Fungi Of Iowa Vi. Fleshy Poroid Forms, Joseph C. Gilman
Illustrations Of The Fleshy Fungi Of Iowa Vi. Fleshy Poroid Forms, Joseph C. Gilman
Proceedings of the Iowa Academy of Science
The fleshy poroid fungi which are illustrated in this paper are found in two of the families of the larger fungi, the Polyporaceae and the Boletaceae. Both families contain so many species that a comprehensive treatment of either could not be undertaken in the space available for this series of illustrations. Therefore only five very conspicuous and common species are presented.
Microclimatic Differences In Minimum Temperature And Variations In Frost Injury To Hillculture Plants, J. M. Aikman, G. L. Brackett
Microclimatic Differences In Minimum Temperature And Variations In Frost Injury To Hillculture Plants, J. M. Aikman, G. L. Brackett
Proceedings of the Iowa Academy of Science
Quantitative investigations of climatic factors in the immediate habitat of both native and cultivated plants in the field and of the effect of these factors on the growth of the plants have proved that climatic factors may vary sufficiently within relatively narrow limits in space to produce significant variations in the development of plants. These contributions have had an important influence on the growth of the concept of microclimate and on the recent interest and research in this field. At present there is urgent need of information on the determination of the size of microclimatic areas and of the critical …
The Spread Of Perennial Sow Thistle In Iowa, Ada Hayden
The Spread Of Perennial Sow Thistle In Iowa, Ada Hayden
Proceedings of the Iowa Academy of Science
Sow thistle is not a thistle as the common name implies, but it belongs nevertheless to the Thistle Family, Compositae. The genus Sonchus, according to Hegi (1931), is widely distributed in cultivated parts of the temperate and even the subtropical world, and the four ruderal species, now extending their range in North America, are found in Europe, Asia, parts of Africa, and South America. They include the perennials Sonchus arvensis L. and Sonchus arvensis L. var. glabrescens Guenth., Grab., and Wimm. as well as the annuals Sonchus asper (L.) Hill and Sonchus oleraceus L.
Rubber Industry Of West Africa, Robert M. Warner
Rubber Industry Of West Africa, Robert M. Warner
Proceedings of the Iowa Academy of Science
The rubber industry began in West Africa by native exploitation of the wild rubber sources found in the tropical rain forests. The best quality of rubber was obtained from the tree, Funtumia elastica Stapf. and the vines Landolphia ovariensis Beauv. and Clitandra cymulosa Benth. The tapping methods were usually destructive and eventually new areas were difficult to find. As plantations of Manihot glaziovii Muell. Arg., the para rubber tree, and Hevea brasiliensis (H. B. K.) Muell. Arg., the para rubber tree, were established the wild rubber became less important. The yields from Manihot proved to be much lower than Hevea …
Modification Of Blood By Zeolites For Transfusion Purposes, Walter J. Sweet, O. R. Sweeney
Modification Of Blood By Zeolites For Transfusion Purposes, Walter J. Sweet, O. R. Sweeney
Proceedings of the Iowa Academy of Science
Richard Lower made the first blood transfusion in 1665, but the wide use of the technique in medicine is quite recent. One of the difficulties lay in the coagulation of the blood during the transfer. Accordingly, the blood is generally treated with sodium citrate to prevent this. It is known that calcium in the blood has something to do with the coagulation and probably with the agglutination. It was decided to study blood from which the calcium had been removed. To remove the calcium we adopted the principle used in removing calcium from hard water, that is, passing· it over …
A Polarographic Study Of Acetphenone And Benzalacetone, Futoshi Takazawa, Lothrop Smith
A Polarographic Study Of Acetphenone And Benzalacetone, Futoshi Takazawa, Lothrop Smith
Proceedings of the Iowa Academy of Science
One of the advantages of polarographic analysis is that, when a mixture of two or more substances is electrolyzed at a dropping electrode in the presence of an excess of supporting electrolyte, each substance will produce its own wave at a characteristic potential and the height of the wave will be proportional to its concentration. However, in the absence of a supporting electrolyte, the wave height for cations being reduced at the dropping electrode is dependent on the presence of another reducible substance. Heyrovsky and Bures (1), (2) first demonstrated that the limiting currents of potassium and sodium ions are …
Phenyl Chlorocarbonate And Substitution Products As Acylating Agents, L. Chas Raiford, J. R. Dudley
Phenyl Chlorocarbonate And Substitution Products As Acylating Agents, L. Chas Raiford, J. R. Dudley
Proceedings of the Iowa Academy of Science
Hinsberg and Udranszky (1) converted 2-aminophenol into the 0- ·benzoyl-N-benzoyl derivative by means of the Schotten-Baumann (2) reaction. Raiford and Inman (3) prepared a number of N-carboaryloxy derivatives of 2-aminophenol by following the method of Groenvik (4) who used ethyl chlorocarbonate as the only reagent. When these compounds were mixed with caustic alkali solution for the purpose of acylating them (2) they were converted into the corresponding benzoxazolones while the required phenols were eliminated. It was further shown that warming 2-N-carboaryloxyaminophenol with pyridine and with acetic anhydride, respectively, caused ring closure, and that in the latter instance there was formed …

Proceedings of the Iowa Academy of Science
Volatile solvents for soybean oil have, from the standpoint of the -soybean processor, two uses: in the laboratory in the determination of the oil content of the beans and in solvent types of oil extraction plants for the removal of the oil.
Spectrographic Studies Of Human Blood, Jo-Fen Tung
Spectrographic Studies Of Human Blood, Jo-Fen Tung
Proceedings of the Iowa Academy of Science
Many of the vitamins in the blood have been investigated by chemical and biological methods including vitamin A by photo-electric colorimetric analysis (1), vitamin B1 by a fermentation method (2), nicotinic acid by a microbiological assay with Shigella paradysenteriae ( 3), pantothenic acid by measuring the growth of such bacteria as Proteus morganii (4), and Lactobacillus casei E (5), vitamin C by 2, 6-dichlorophenolindophenol (6), (7), (8), vitamin D by a colorimetric method (9), and vitamin K by measuring the clotting power of the blood (10). According to the above methods, these vitamins are present in blood and some of …
Seven New Species Of Unassigned Plant Microfossils From The Des Moines Series Of Iowa, L. R. Wilson, R. M. Kosanke
Seven New Species Of Unassigned Plant Microfossils From The Des Moines Series Of Iowa, L. R. Wilson, R. M. Kosanke
Proceedings of the Iowa Academy of Science
The coals of the Des Moines Series of Iowa contain an abundance of unassigned plant microfossils and in this report a few of the more diagnostic new types are described. At the present time little can be stated concerning the vertical distribution of these microfossils but preliminary work has shown that some are definitely restricted to certain strata and should become useful horizon markers as more information is accumulated. In 1940, Wilson and Coe described eleven new species of unassigned plant microfossils from the Des Moines Series of Iowa. Several of these have since been transferred to other genera by …
A Design For Sampling Iowa Families, Bernice Brown
A Design For Sampling Iowa Families, Bernice Brown
Proceedings of the Iowa Academy of Science
The sampling design described in this paper is one which was devised for a survey on Canning and Gardening in Iowa. This survey was initiated by the State Nutrition Council and M. L. Wilson, Director of Extension, United States Department of Agriculture. The sample was designed by the Statistical Laboratory and the investigation conducted by the Extension Service, Iowa State College. The purpose of the survey was to make estimates of 1. Number of quarts of food canned, frozen, and stored by Iowa families; 2. Number and size of 1943 gardens and plans for 1944; 3. The amount of food …
A Mechanical Calculator To Solve The Equation X = [(D+Z+C) .Y / (B+Y)]-C, Zaboj V. Harvalik
A Mechanical Calculator To Solve The Equation X = [(D+Z+C) .Y / (B+Y)]-C, Zaboj V. Harvalik
Proceedings of the Iowa Academy of Science
Mechanical calculators based upon equations that can be interpreted in terms of plane or spherical geometry are easily to construct and to operate. They mostly are precise enough for practical applications. The time of adjustment and calculation is very short, and therefore this kind of device will be welcome whenever time plays an important role.
The Mechanism Of Gravitational Force, E. E. Watson
The Mechanism Of Gravitational Force, E. E. Watson
Proceedings of the Iowa Academy of Science
Although it has been known since the time of Newton, nearly three centuries ago, that bodies attract each other according to the law of inverse-squares, no explanation as to how gravitation operates has been accepted. However with our present knowledge of matter it would seem that some explanation should be possible. Keeping in mind Newton's first law of motion, namely, "Everybody continues in its state of rest or of uniform motion in a straight line unless compelled to alter that state by impressed force", let us consider for the purpose of illustration an atom within the motion is that produced …
