The U.S. Nitrogen Fertilizer Industry: Economics of Plant Size and Utilization Projected to 1970
In 1965, the University of Nebraska entered into a contract with the Farmer Cooperative Service of the United States Department of Agriculture to analyze the conditions of supply, demand, price, and capacity of the nitrogen fertilizer industry in the United States, and to project these variables through 1970. This thesis is based on a report by the author which partially fulfilled the requirements of the contract.
The purpose of this study was to present the historical trends in nitrogen fertilizer consumption, costs, and prices, and to project these trends through 1970 for each region of the United States. The primary contribution of the study is to estimate the effect of economies of plant size and utilization on costs and alternative pricing strategies.

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Changing landscapes in the Garden State: land use change in New Jersey 1986 through 2015
The analysis reported on herein represents an analysis of the change in the state’s land use/land cover occurring between the spring of 2012 and spring of 2015 based on the New Jersey Land Use/Land Cover Change (NJLULCC) data set. LULCCC data across a longer time frame, back to 1986, are analyzed to put this more recent time period in context. Conversion of green space to new urban development in New Jersey has continued to slow from its historic high pace of new urban development in the 1990’s and 2000’s. Between the year 2012 and 2015, New Jersey expanded the amount of urban land by 10,392 acres, equivalent to a rate of 3,464 acres of new urban development per year. This rate represents a continuation of the trend of decreasing urban development initiated during the Great Recession of 2008. In comparison, urban development grew at a pace of 16,852 acres per year in the late 1990’s. Over the 2012 to 2015 time period, New Jersey had a population growth rate of 0.3% (from 8.85 million in 2012 to 8.87 million in 2015) and an urban growth rate of 0.7% (from 1.56 to 1.57 million acres). The three year period from 2012 to 2015 saw population growth occurring at less than the rate of urbanization, although the magnitude of both rates of change has declined significantly over the 29 year study period
Changing landscapes in the Garden State: land use change in NJ 1986 through 2012
This report is part of an ongoing series of collaborative studies between Rutgers and Rowan Universities examining New Jersey’s urban growth and land use change. The New Jersey Land Use/Land Cover Change data set utilized for the analysis represents a detailed mapping of the land use and land cover as depicted in high resolution aerial photography that was acquired in the spring of 2012. The imagery was then classified and mapped providing a window into how the Garden State has developed over the past several decades (from 1986 through 2012) and the subsequent consequences to its land base. It views land development patterns from several different angles providing a “report card” on urban growth and open space loss
Measuring urban growth in New Jersey: a report on recent land development patterns utilizing the 1986 - 1995 NJ DEP land use/land cover dataset
This report is an excerpt of research on measuring urban sprawl in New Jersey being conducted at Rutgers University. The primary data source employed in this analysis is the New Jersey DEP land use/land cover digital database, which contains detailed land use change information for the period of 1986 to 1995. This data set provides a unique window into the landscape changes that have been occurring in the Garden State at the end of the 20th century.
The changes revealed in the data set are remarkable. Every year New Jersey adds approximately 16,600 acres of new development while losing more than 9,600 acres of farmland, 4,200 acres of forest, and 2,600 acres of wetlands. Impervious surface is being created at the rate of 4,200 acres per year. The net new land developed during the nine year 1986 to 1995 period of this analysis was 135,764 acres, an area equal to the total land area of Union and Essex counties combined. Put on a more comprehensible scale, the daily urban growth rate in New Jersey was equivalent to adding 41 football fields worth of new urban land every day while losing 20 football fields of farmland, 9 football fields of forest and 6 football fields of wetlands. Impervious surface was created at the rate or 9 football fields of coverage per day. If development continues at this rate and if New Jersey successfully preserves a million acres of open space, the remaining available land would be developed in about 40 years. This development rate is likely to make New Jersey the first state in the nation to reach build-out. The following report is intended as a step in developing knowledge about New Jersey’s changing landscape. It is our hope that a better understanding of these land development patterns will contribute to wiser land management policies and practices in New Jersey in the coming years

State of the Raritan Report, Volume 1, December 2016
This report updates key indicators of water quality and watershed health for the Raritan Basin that were originally assessed in the 2002 Raritan Basin: Portrait of a Watershed as developed by the New Jersey Water Supply Authority. The objective of that original report, as well as this update, is to inform watershed management and water supply protection needs in the Raritan Basin. This new assessment uses the same eleven key indicators and updates the original data – most from 1986 and 1995 – with data from 2002, 2007 and 2012 in order to determine trends over the past 26 years and to identify data gaps for development of future more comprehensive assessments.Eleven key indicators were assessed for this report including: population; housing units; urban land use; impervious surface cover; forested, coastal and emergent wetlands; upland forest cover; prime agricultural land; groundwater recharge; fish and macroinvertebrate bioassessments; riparian area integrity; and known contaminant sites and groundwater contamination. Overall comparison of this updated analysis with the prior 2002 report (Table 1) shows that trends evident between 1986 and 1995 are continuing in the same general direction though the rate has varied over the longer time period. Trends increased for population, housing units, urban land use and impervious surface cover. An increasing trend for these indicators adds stress on water quality and supplies with potential negative impacts for the watershed. Trends declined for all of the wetland land covers assessed as well as for upland forest, prime agricultural land and groundwater recharge. Downward trends for these indicators suggests that the watershed is losing its natural filtering capacity with attendant negative impacts to water quality. The bioassessment and riparian areas trends were mixed and there was not sufficient data to determine trends for the known contaminated sites and groundwater contamination indicators.more information about report and effort at: http://raritan.rutgers.edu/2016-state-of-the-raritan-report/Authored by the Sustainable Raritan River Initiative.

Some Ion-Bombardment Effects on Copper-Gold Alloys
Title: Some Ion-Bombardment Effects on Copper-Gold Alloys, Author: Richard G. Newcombe, Location: ThodeThis report discusses some of the effects of medium-energy ion-bombardment on various copper-gold alloys. Thin (20nm-150nm) films of copper-gold alloys, on Si or SiO2 substrates, were bombarded with 30keV Ar+, 45keV Ar+, or 45 keV Bi+ ions, to fluences of up to 8 x 10^14 ions/mm2. One of the targets was held at ~50°K; the others were irradiated at room temperature. The effects were observed by 1.00 and 2.00 MeV He+ ion Rutherford backscattering. The results are discussed in terms of preferential sputtering, gas trapping, and surface topography.ThesisMaster of Engineering (ME

Kentucky Fighting Men: 1861-1946
Kentuckians by the thousands have fought in all of the American wars of the industrial age. Fathers, sons, and brothers from the Bluegrass State spilled each other’s blood in countless Civil War battles and skirmishes. Over the next century their descendants bore arms on the seven seas, the Far Western frontier, in the Caribbean and Philippine islands, and in China. Kentuckians took part in both world wars of the twentieth century in every capacity. Kentucky Fighting Men, 1861–1945 features individual Kentuckians who represent the overall context of the American military experience from the Civil War through World War II. Richard G. Stone, Jr. presents accounts that illuminate the heroism, ennui, tragedy, ghastly horror, absurdity, and the infinite variety of warfare and military life.
Richard G. Stone, Jr., professor of history at Western Kentucky University, is also the author of A Brittle Sword: The Kentucky Militia, 1776–1912.https://uknowledge.uky.edu/upk_military_studies/1005/thumbnail.jp
