Investigation on the Effect of Drillstring Stiffness on Downscaling Drillstring Vibrations
(2021-05-16)Drillstring vibrations provide one of the most important challenges to drilling efficiency today. These vibrations can cause many issues such as decreased energy transfer from the to drive to the bit, fluctuating drilling ... -
Investigations into the mechanism of action of a fish pituitary hormone /
(The University of Oklahoma., 1970) -
Investigations into the neurodegenerative mode of action of dihydroxytetrahydroquinoline derivatives.
(1997)Preliminary testing of a dihydroxyguinoline derivative, 3-amino-6,7-dihydroxy-1,2,3,4-tetrahydroquinoline (6,7-ADTQ), showed substantial serotonergic depletion in mouse whole brain, but with only moderate selectivity. This ... -
INVESTIGATIONS OF CARTILAGE LUBRICITY AND INTERACTIONS BETWEEN CARBON NANOTUBES AND PHOSPHOLIPID BILAYERS
(2012)Because one of the principal functions of articular cartilage in joints is to provide support in diarthrodial joints, transmitting loads with minimum friction and wear, it is likely that understanding the lubrication ... -
Investigations of interspecies transfer mechanisms important to syntrophic metabolism
(2011)Syntrophy is a tightly coupled mutualistic interaction among microorganisms that is essential for the global cycling of carbon in essentially all anaerobic environments. Syntrophic degradation of aromatic, alicyclic and ... -
Investigations of microbial diversity and microbial interactions in a contaminated aquifer and experimental evolution of Desulfovibrio vulgaris Hildenborough
(2024-05-10)Investigating the mechanisms underlying microbial diversity is one of the challenges in microbiology. The dimension of diversity typically includes three aspects: taxonomic diversity (TD), phylogenetic diversity (PD), ... -
Investigations of Secondary Metabolites from Fungi: Isolation, Structure Elucidation, and Computational Studies
(2018-12-14)Natural products have served as therapeutic agents in the treatment of many human health ailments for thousands of years. In order to find new therapeutic agents for future human health problems, those in the field of ... -
Investigations of secondary metabolites from fungi: isolation, structure elucidation, and semi-synthetic studies
(2022-12-16)Trichomoniasis, caused by Trichomonas vaginalis remains a worldwide threat, afflicting an astonishing 3.9% of the world’s population. This parasite is recognized as a cause of vaginitis and can result in serious health ... -
Investigations of the effects of iron, manganese, and nickel on the properties of sulfated zirconia catalysts.
(1997)Thermogravimetry (TG) was utilized to study catalyst thermal stability and to measure sulfate contents for catalysts with differing compositions. Temperature programmed desorption (TPD) measurements of surface adsorbed ... -
Investigations of the Mechanical and Microstructural Properties of the Atrioventricular Heart Valve Leaflets and Chordae Tendineae
(2020-05)The unidirectional blood flow through the heart is facilitated by the atrioventricular heart valves – namely the mitral valve and the tricuspid valve. The two atrioventricular heart valves (AHVs) are composed of soft tissue ... -
Investigations of the Mechanical Properties and Microstructure of the Atrioventricular Heart Valve Leaflets
(2019-05-10)Atrioventricular heart valves (AHVs), namely the mitral and tricuspid valves, regulate unidirectional blood flow from the atria to the ventricles in the left and right sides of the hearts, respectively. These valves can ... -
Investigations of the Microstructural and Mechanical Properties of the Four Heart Valves
(2021-05)The four heart valves (HVs) regulate the unidirectional flow of blood throughout the four chambers of the heart. The artioventricular heart valves (AHVs) enforce this unidirectional flow between each atrium and the respective ... -
Investigations of the properties of some enzymes in Nocardia corallina and tobacco tissue /
(The University of Oklahoma., 1970) -
Investigations of the Tricuspid Heart Valve Function: An Integrated Computational-Experimental Approach
(2019-05-10)The objective of this research is to employ both in silico modeling and in vitro experimental characterization methods to enhance the understanding of the biomechanical function of the tricuspid heart valve. A finite ... -

INVESTMENT-PROMOTION POLICIES AND EMPLOYMENT BY FOREIGN FIRMS IN THE US STATES
(2012)This study examines the relationship between state-level attributes and employment outcomes of US inbound Foreign Direct Investment (FDI). In particular, I investigate how investment-promotion policies influence the ... -
Investors' Reactions to Management Earnings Forecasts: The Effects of Changes in Forecast Precision and Investor Preferences
(2014)This study examines the effects of changes in management earnings forecast precision (i.e., changes in the width of the forecast range) and investor preferences on investor judgments. In general, prior research finds that ... -
The Invisible Artist: The Editor's Perspective on Rhetoric, Ethics, and Representation in Film Editing
(2024-05-10)This dissertation explores the impact that the film editor has on films and what their beliefs are when it comes to the content that they create. Examining history, this dissertation shows that film editors have always ... -
Invisible Minority: Military-Connected Adolescents in Secondary Schools
(2018-12-14)Military families and military-connected children are a vital source of support – the backbone for soldiers fighting in our armed forces. There are currently four million military-connected children in the U.S. and 80% of ... -
