Ten algal isolates were obtained from soil into axenic culture and placed into defined media containing from 0 to 50 ppm of DDT, 2, 4-D,2,4,5-T, rotenone, or malathion (in two purities, 95 and 99%). For nine of the isolates, growth was measured...
Equations of state attempt to describe the relationship between temperature (T), pressure (P), and molar volume (v) for a given substance or mixture of substances. The ideal gas law is the simplest form of an equation of state. An ideal gas can be...
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
Accelerated life testing; Reliability (Engineering); Service life (Engineering)
This dissertation is focused on finding lower confidence limits for the reliability of systems consisting of Wei bull components when the reliability demonstration testing (RDT) is conducted with zero failures. The usual methods for the parameter...
A new procedure has been developed for determining
the location of the source of certain EEG discharges
given the measured surface potentials. The
source is modeled as a single current dipole with arbitrary
position and orientation, while the head...
The purpose of this study was to determine if training has a protective effect on endothelial function following the consumption of a high-fat meal. Twenty young males classified as trained or untrained underwent vascular and blood lipid testing...
Interactions between chemokines and their receptors are involved in organ- specific homing and propagation of metastatic breast cancer (BrCa) cells. BrCa cells express higher levels of CXCR4 and CXCR7 mRNA and cell surface protein, than normal...
Standard regularity assumptions for regression models are not satisfied in segmented regression models with an unknown change point, and consequently standard asymptotic results and inferential methods for confidence estimation are not applicable....
Many businesses have poor IT infrastructure and are in need of a major overhaul. University of Louisville Properties (ULP), in particular, needed the ability to share files between staff, backup data, secure data, and eliminate viruses and malware....
The airline regulatory communities are interested in methods that can access degradation in the polymer insulation of aging aircraft wiring. This study investigates the response of bulk polymer films and aircraft wiring under indentation; changes...
The use of a fluidized bed dryer to dry acrylo-nitrile-
butadiene-styrene terpolymer was studied. Data for
fluidized bed drying were obtained from the Monsanto
Company's fluid bed dryer. Fluid bed theory, drying
phenomena, and fluid bed drying...
Osteoporosis in women--Prevention; Osteoporosis--Treatment; Hip joint--Fractures--Prevention
Low-trauma fractures of older women are a major public health burden. Fractures of the hip and spine are some of the primary causes of chronic pain, functional impairment, and disability among the elderly [1]. The underlying cause of these...
The objective of this thesis is to develop computer programs for the dynamic analysis of structures. For a shear building two computer programs were developed: (1) Dynamic Analysis of a Shear Building within the Elastic Range and (2) the Dynamic...
Genes in folate metabolizing pathway are responsible for modulating key enzymes in folate metabolisms necessary for DNA synthesis and repair and influence DNA methylation. Irregularity in DNA methylation may modify tumor phenotype response to...
The Y family of DNA polymerases in higher eukaryotes contains at least four members which are implicated in potentially error-prone replication through unrepaired damage in the genome. These proteins are encoded by the REV1, POLH, POLI, and POLK...
Marginal inference for waiting times in multi-stage time-to-event models is complicated by right censoring of observations as well as the prior history of events in the model. In general, complications arise due to the evolution of the censoring...
The revolution in information technology and the explosion in the use of computing devices in people's everyday activities has forever changed the perspective of the data mining and machine learning fields. The enormous amounts of easily...
Item response theory; Goodness-of-fit tests; Monte Carlo method
Item response theory (IRT) is expanding to diverse research settings, without accompanying access to easily implemented model fit methods. One simple model fit approach involves x2/df ratios. However, its utility is not known across several...
Academic achievement--Psychological aspects; College students--Psychology
Researchers have studied the concepts of optimism and pessimism as traits, expectations, strategies, and styles of explaining outcomes. Explanatory style and the strategy of defensive pessimism are two of these areas. In general, optimistic...
