Sex variability
(University of Missouri--Columbia, 1919)
in considering very diverse aspects of the physical and psychic phenomena of human life. One of these is the greater variability of the male; this is true for almost the whole of the field we have covered, and it has social and practical consequences...
The relation of size, shape, and number of replications of plats to probable error in field experimentation
(University of Missouri--Columbia, 1916)
of the methods used, the need for attention along this line becomes strikingly evident. It has been demonstrated repeatedly that even soils which possess apparent uniformity really vary a great deal. This variation is often so great as to cast doubt on a large...
The psychology of the Negro
(University of Missouri--Columbia, 1916)
Text from introduction: Though the term "race psychology" has been in use, for some years, the amount of scientific evidence of the existence of racial differences in mentality is very small. In America, where so many races meet and contribute...
Relation of lime and magnesium to plant growth in Missouri soils
(University of Missouri--Columbia, 1906)
with success; sometimes with medium results and sometimes with apparent failure. SIR JOHN BENNET LAWS and SIR JOSEPH HENRY GILBERT were the first to make accurate observations upon the practice of liming. They found that the white or "fat lime" would produce...
The psychology of the Negro
(University of Missouri--Columbia, 1914)
races meet, the problem of racial differences is an important one for our educational theory and practice, as well as our social philosophy. This is especially true in our Southern States, where there are vast numbers of white and colored children...
An investigation of the relation between vegetative and reproductive activity in plants
(University of Missouri--Columbia, 1916)
"It is the purpose of this investigation to study this relationship between vegetative and reproductive activity, to present evidence showing to what extent it may be influenced and modified by external conditions or cultural practices, and in so...
The effects of various planes of nutrition upon the cost of maintenance, reproduction, and development of beef cows
(University of Missouri--Columbia, 1916)
The frequency with which valuable animals reproduce themselves has always been a factor of economic importance in the pure bred cattle business. Great economic changes during the last few years have made this an important ...
Variation in the carbohydrate and diastase contents of the tissues after feeding
(University of Missouri--Columbia, 1918)
. His work followed Bernard's (5) discovery of glycogen in 1857, who a little later independently produced similar evidence of glycogenase. Pavy (6) in 1879 corroborated these results of Wittich in 1873, and of Bernard in 1877, extracting the enzyme from...
The minimum protein requirement for growing dairy heifers
(University of Missouri--Columbia, 1918)
with such large farm animals as dairy heifers. Consequently the results cannot be entirely satisfactory from a scientific standpoint. Yet if such experiments are properly controlled they should give results of value both scientifically and practically."...
A re-evaluation of the kernos, with special reference to the kernos in Demeter's rites
(University of Missouri--Columbia, 1978)
The focus of this paper has therefore become the objects excavated throughout the Mediterranean, which have been called "kernoi." An examination of these vessels of various shape and a survey of the finds from excavated ...
The killing of plant tissue by low temperature
(University of Missouri--Columbia, 1914)
The term freezing to death is applied to a very specific set of phenomena in plants. With all plant tissues, when a certain temperature is reached very shortly after thawing, it will be found that the tissue has taken on ...
Winter rations for dairy heifers
(University of Missouri--Columbia, 1918)
"Comparatively little experimental data are as yet available concerning these problems of raising heifers. The purpose of the author in conducting the experiments reported in this thesis was to add to the data now available ...
The action of Digitalis on the cardiac inhibitory centre
(University of Missouri--Columbia, 1914)
So long has digitalis been in use as a clinical drug and so long has its action been the subject of experimentation that it would seem that there is little hope of presenting anything new on the subject. Yet so long as ...
The investigation of technical orthochloronitrobenzene
(University of Missouri--Columbia, 1918)
methods which are given and to determine a practical method of separation. There is no doubt that a method of this kind will be of great practical value since both of the compounds are valuable in the synthesis of many important and necessary products...
Cytological study of the development of the functional activity of nerve cells in foetal and infantile animals
(University of Missouri--Columbia, 1913)
was to investigate to what extent early changes of function correspond to adult changes and to trace the progress of development. This has been done principally in terms of the nucleus-plasma relation theory of Richard Hertwig. This article is based principally...
Minimum protein requirements for the growth of dairy heifers
(University of Missouri--Columbia, 1915)
herein. It has not been the intention to show the relative value of different rations. The practical value of the experiment will lie in the results obtained rather than in the methods used....
Study of the phenomenon of barrenness in corn
(University of Missouri--Columbia, 1911)
and comment to both practical farmers and agricultural investigators as well. Strange as it may seem, however, there has been practically no work done to discover why the maize plant, or any other grain normally bisexual, should be sterile. Many theories have...
Factors affecting the growth of dairy animals
(University of Missouri--Columbia, 1916)
and developed, and for this reason the problen of determining the growth-regulating factors is one of great importance from a practical standpoint....
The interrelation of mental functions
(University of Missouri--Columbia, 1919)
"The aim of this dissertation is to review the most important results published up to the present time, and to add a statement and discussion of results obtained in the laboratory of educational psychology at the University of Missouri." -- Pages 1-2....
