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

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

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

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

Hay: A Hedonic Study

Hedonic price theory posits that the price of a product is influenced by the values consumers assign to its individual attributes. Hay is a versatile commodity with variation across several attributes helping to cater to diverse needs of consumers. A detailed analysis using hedonic regression techniques within hay pricing can help producers, stakeholders, and educators more fully understand the marginal values consumers place on diverse hay attributes. Previous studies focused on limited scopes within the hay industry or other sectors, allowing room for broader investigation. This study examines qualitative attributes impacting hay pricing, revealing significant influences from factors like location, seed type, and quality. Notably, California and Texas are found to command higher marginal prices relative to other western states, while certain hay varieties and smaller bale sizes are also identified as having higher comparative marginal value on average. Identification of the average marginal values of individual hay attributes offers valuable insights into the dynamic hay industry
