The Systhesis Of Camphor From Pinene, Edwin W. Newbury

Bachelors’ Theses

The increasing demand for camphor for use in the manufacture of cellulose plastics has led to a great amount of investigation of the nature of this valuable substance and as to its synthesis from materials which are readily obtainable without the necessity for sending overseas for them. At present most of the camphor used in the manufacture of celluloid and allied compounds is imported from Japan or Borneo, where it is obtained, in a rather crude and wasteful fashion, from a species of laurel. Some scientifically operated camphor plantations have been started in the United States.. In one such plantation …

Assay Of Copper Matte For Gold And Silver, Walter E. Soest

Bachelors Theses

"Ores containing copper, and especially copper matte, have always been very annoying in assaying for the precious metals. In assaying copper matte, and ores containing much copper, by the usual method of scorification, the losses of silver an gold are considerable, owing to the fact that in order to obtain lead buttons, which are soft and free from copper, repeated scorifications are necessary, and moreover it is impossible to obtain lead buttons which are entirely free from copper"--page 1.

The Neocene Lake Beds Of Western Montana And Descriptions Of Some New Vertebrates From The Loup Fork, Earl Douglass

Graduate Student Theses, Dissertations, & Professional Papers

Since coming to Montana in the spring of 1894 I have spent rnuoh of ay time in studying the lake bed deposits in the western part of the state, and in collecting and studying the vertebrate fossils found in them. These deposits occur in nearly every large valley in the westem part of the state. I have myself observed them in the valleys of the upper Missouri (above the re-rrion of Helena), Gallatin, Madison, Jefferson, Beaverhead, Ruby, Big Hole, Hell Gate, and Bitter Boot rivers, and their tributaries.

Producer Gas, Edward P. Dwyer

Bachelors Theses

"Producer gas, so named owing to being produced in special forms of apparatus known as Producers. The fuel is decomposed into combustible gases, whereby most of the C is burnt to CO, whilst the H either remains free, or is converted into carburretted Hydrogen. Directly above the grate carbonic anhydride is formed but thus is rapidly converted into carbonic oxide; reaction as follows: CO₂ + C = 2CO.

Amongst these heavy carburetted hydrogen (C₂H₄) is that which principally increases the value of the gas as fuel and the drier the fuel used the more of the gas is produced. A …

Studying Properties Of Xenon Doped Argon And Developing Optical Simulation Techniques For The Legend Collaboration, A Neutrinoless Double Beta Decay Experiment, Neil Christopher Mcfadden Dr

Physics & Astronomy ETDs

Neutrinoless double beta decay is a hypothesized lepton-number-violating process in which two neutrons decay to two protons, producing two electrons but no electron antineutrinos. The LEGEND collaboration will search for this decay in ⁷⁶Ge. To improve the argon active veto for LEGEND-1000, xenon doped argon was explored as an alternative active volume. Simulations using argon doped with 10 ppm xenon and pure liquid argon were used to predict the light yield from cosmic muons in a 100 liter cryogenic vessel. The simulations predicted that xenon doping would yield 1.83+/-0.02 more light, while an increase of 1.81+/-0.05 was measured. From …
