Monte Carlo simulation of the classical two-dimensional one component plasma
Monte Carlo simulation, lattice dynamics in the harmonic approximation, and solution of the hypernetted chain equation were used to study the classical two-dimensional one component plasma. The system consists of a single species of charged particles immersed in a uniform neutralizing background. The particles interact via a l/r potential, where r is the two dimensional separation. Equations of state were calculated for both the liquid and solid phases. Results of calculation of the thermodynamic functions and one and two particle correlation functions are presented
Biographical Note on Persoon
Although the name and works of Christian Hendrik Persoon are well known to most botanists, the biography of this illustrious mycologist is not. This fact is attributable to the following reasons: the dearth of accurate information; incompleteness of any biographical account; and the difficulty involved in finding that material which is available. An attempt is made here to alleviate this situation
Geology and Mineralogy of the Wellington Mine, Breckenridge, Summit County, Colorado
Submitted in partial fulfillment of the requirements for the degree of Master of ArtsIncludes oversized supplementary maps and a graphText from page 3: This paper is based on work done during the summer of 1915, while the writer was a member of a field party, engaged in geological work in the vicinity of Breckenridge, Colorado. Through the kindness of Mr. R. M. Henderson, manager of the Wellington Mines Company's property, permission was secured to examine the underground workings of the Wellington mine, the most important zinc-lead mine in the Breckenridge district. Plans showing the location of the principal drifts and stopes were furnished by Mr. Henderson, and, with these maps as guides, the writer made quite a thorough survey of the workings, determining, as far as possible, the geology and mineralogy of the mine. Many specimens of the country rock and the minerals were secured, and intensive study was made of them in the laboratory during the past winter
Lignin, Cellulose and Crude Fiber Changes in Maturing Western Wheatgrass: (Agropyron smithii Rybd.)
It can be said from observations that plants become more woody as they mature. A young plant is relatively tender and supple, whereas an older plant is tougher and has greater strength structure. The nature of this woodiness and its effect upon the digestibility of plants and plant products by animals is of some concern
Protein Metabolism in Rats with Tumors of the Liver
The purpose of our study was to determine possible alteration in water, fat, and protein content of the livers from rats fed DAB for long periods. Aliquots were used for the protein determinations
