The absolute measurement of electrical capacities
(University of Missouri--Columbia, 1913)Of the various methods in use at the present time for the absolute measurement of electrical capacities in electromagnetic units, none give the satisfaction desired. Only two of these methods are in common use and they ... -
The acceleration of gravity : an absolute determination with a Kater's pendulum for Columbia, Missouri
(University of Missouri--Columbia, 1913)Galileo Galilei (1564-1642) was the first to question the assertion of Aristotle that bodies fall with velocities proportional to their weights. He dramatically refuted this Aristotelian doctrine by dropping from the Tower ... -
The [alpha]-rays and the [alpha]-particle : a study of ionization and allied phenomena produced by [alpha]-rays
(University of Missouri--Columbia, 1910)As a result of experiments by M. Henri Beoquerel in 1896 we now know a certain class of chemical elements as Radio-active. A radio-active body gives off radiations that have the following effects: 1) they will affect a ... -
The atomic weight of lead from samarskite
(University of Missouri--Columbia, 1918)Text from page 1: In the disintegration of the radioactive elements, since each a-transformation involves the loss of an atom of helium and nothing else which in weighable, the atomic weight of the product should be just ... -
Cathode disintegration
(University of Missouri--Columbia, 1911)It has been pointed out that the cathode disintegration depends upon the gas present as well as upon the metal of which the cathode is composed. Hence it was thought interesting to investigate whether the gas in which the ... -
Computational studies of methane adsorption in nanoporous carbon
(University of Missouri--Columbia, 2012)In this thesis we have completed computational studies using Grand Canonical Monte Carlo on the adsorption of methane into a graphitic nanoporous adsorbent with slit-shaped pores. Simulations were done at a temperature of ... -
Effect of temperature, density, and strength of electric current on the spectra of gases
(University of Missouri--Columbia, 1901)Light may be defined as that vibration of the ether which, acting on the organ of sight, produces in us the sensation of vision. But when, on reflection, we realize that the sense of sight is the most useful of all man's ... -
Electrolytic rectifiers
(University of Missouri--Columbia, 1912)More than a half-century ago, Wheatstone, in experimenting with the electro-chemical behavior of certain elements, laid the foundation for the modern chemical rectifier. In the year 1855, he found that aluminum as anode ... -
The enigmatic thirteen micron feature
(University of Missouri--Columbia, 2013)Low and intermediate mass stars (0.8--8 solar masses) will eventually evolve into Asymptotic Giant Branch (AGB) stars and pulsate out their atmosphere into the space around them. That ejected material will eventually cool ... -
An in-vitro study of the effects of microwave-induced hyperthermia on the cytotoxicity and cellular uptake of resveratrol gold nanoparticles in prostate and pancreatic cancer cells
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cancer has become the second leading cause of death in the United States over the past decade. While conventional methods of treatment such as ... -
Investigating the formation mechanism of polycyclic aromatic hydrocarbons and adapting particle swarm optimization techniques to search large data sets
(University of Missouri--Columbia, 2010)The unidentified infrared bands (UIBs) have been attributed to emission from polycyclic aromatic hydrocarbons (PAHs). The UIBs at 3.3 and 11.3 [mu]m, among others, are seen in many astrophysical environments, with the ... -
On the astromineralogy of the 13 [mu]m feature in the spectra of oxygen-rich AGB stars
(University of Missouri--Columbia, 2006)Approximately half the oxygen-rich AGB stars to be investigated spectroscopically exhibit a feature at 13 [mu]. The carrier of this feature has not yet been unequivocally identified, but has been attributed to various dust ... -
Paramagnetic and diamagnetic substances and the effect of temperature on them
(University of Missouri--Columbia, 1901)In the latter part of the eighteenth century only a few substances, such as iron, nickle, and cobalt were thought to possess magnetic properties. Little by little, research work has gone on until now, it is believed that ... -
The reversibility of the adsorption of methane-methyl mercaptan mixtures in nanoporous carbon
(University of Missouri--Columbia, 2011)Methane is the main constituent of natural gas (NG). As fuel for vehicular applications NG requires sorbents that allow efficient, reversible and safe storage at room temperature and moderate pressure. To enable easy human ... -
A study of bacterial ribosome 70S complex using smFRET analysis
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Ribosome is a fundamental molecular machine found in all cells and is responsible for synthesizing proteins.(Lehninger Principles of Biochemistry ...
