A-phi scintillation counters in the D0 detector upgrade
(Northern Illinois University, 1999)Because of the upgrade in the accelerator at Fermi National Accelerator Laboratory, the collider detectors also needed to be upgraded. In the case of the D0 detector, the detector upgrade includes changes to the muon ... -
A.C. mutual inductance bridge for low temperature magnetic transition measurements
(Northern Illinois University, 1987)The design of a mutual inductance coil assembly and its use as the detection device of an inductance bridge (modified Hartshorn bridge) is described. The coil was used to measure the superconducting transition temperature ... -
Ab initio studies of pericyclic reactions involving phosphorus substituted alkenes and alkynes
(Northern Illinois University, 1997)The Diels-Alder Reaction between 1,3,5-triphosphabenzene and phosphaacetylene, forming tetraphosphabarrelene, was examined. This reaction was then compared to its carbon analogue (benzene + acetylene). The phosphorus ... -
Ab initio study on pericyclic reactions involving heteroatoms
(Northern Illinois University, 1998)This thesis consists of work involving use of computational chemistry for studying the reactions of heteroatomic systems. It is interesting to observe how the reaction mechanism for classical organic reactions are affected ... -
Ab-Initio supercell calculation of an isolated neutral silicon vacancy for the investigation of the properties relating to deep centers
(Northern Illinois University, 2005) -
Abandonment behavior and the archaeological record
(Northern Illinois University, 1993)The way in which people abandon a site affects the patterning of artifacts and the other materials that make up the archaeological record. This thesis analyzes the way in which abandonment behavior can be seen archaeologically ... -
The absence of TGA codons in the DNA sequence of the Phytophthora megasperma gene for cytochrome c oxidase subunit II
(Northern Illinois University, 1989)Previous characterization of P. megasperma mitochondrial DNAs revealed two genic inversions between a host-specific and a nonspecific strain. As part of a characterization of oomycete mitochondrial genomes, studies of the ... -
AC-DC boost converter stability analysis based on open loop measurement
(Northern Illinois University, 2002) -
The academic success of unmarried African-American female high school students who are parenting

The Academy Festival Theatre Company : from debut to demise
(Northern Illinois University, 1992)Of all the arts in America, the theatre has perhaps the largest number of participant organizations. There are some fifteen thousand non-professional and educational theatres in the United States. The present study attempts ... -
Accelerated life testing of a notched aluminum beam
(Northern Illinois University, 2004) -
Accelerated testing of components made by additive manufacturing
(Northern Illinois University, 2015)Additive manufacturing, commonly known as 3D printing, has revolutionized manufacturing and it is finding applications from simple structures to aerospace. For automotive and aerospace applications, vibration is a big ... -
Accounting for death : press coverage of the 1981 Northern Irish hunger strike
(Northern Illinois University, 1990)During 1981, 10 inmates of the Maze Prison in Northern Ireland went on hunger strike in pursuit of "political prisoner status." Their action was an effort to establish the legitimacy of the use of violence to achieve ... -
Accuracy measures of absolute and relative performance appraisal methods
(Northern Illinois University, 1995)This study investigated the accuracy of two formats for the appraisal of performance, specifically relative and absolute. The primary question of this experiment was whether relative and absolute performance appraisal ... -
The accuracy of mapping derived from the General Land Office surveys: : presettlement wetlands and deepwater habitats within Lake County, Illinois
(Northern Illinois University, 1992)The accuracy of mapping derived from of General Land Office survey (GLO) data for a portion of Lake County, Illinois is assessed. This study is based upon similar research conducted by Iverson and Risser in 1987. Due to ... -
Accurate motion time prediction of robot point-to-point operations
(Northern Illinois University, 1991)Manufacturing systems require accurate information on the cycle times of member machines for efficient scheduling to maximize machine utilization and productivity. The industrial robot is a key element of an automated ... -
Achievement Motivation : the effects of conscious, chronic, and nonconscious goals on task performance
(Northern Illinois University, 2007)Work motivation theorists have only recently addressed the importance of studying nonconscious motivation in addition to conscious motivation and the relationship between the two. The primary purpose of the current ... -
Acoustic emission monitoring of multi-phase fluid flow in laser-engineered net shaping process (LENS)
(Northern Illinois University, 2015)The Laser Engineered Net Shaping (LENS) Process uses an argon stream to direct metallic particulates at a molten pool created by a high-power Yb-fiber laser. The LENS process uses numerical control (NC) to manipulate the ... -
The acoustic startle response in young and aging C57BL/6J and CBA/J mice
(Northern Illinois University, 1987)C57BL/6J mice demonstrate progressive age-related hearing loss during the first year of life, while CBA/J mice lose little sensitivity through 18 months of age. The acoustic startle response (ASR) was measured in these ... -
The acoustics of a Karen bronze drum
(Northern Illinois University, 1999)Bronze drums are important to the culture of the Karen people, who live mainly in Burma and the mountainous region between Burma and Thailand. A Karen bronze drum, which is cast in one piece, consists of an overlapping ...
