(2023-05-05)Solid deposits form when a lubricant undergoes thermal breakdown due to high-temperature conditions and can cause adverse operational effects within engines. A collection device designed to allow coke to form on its surface ...
-
(2017-07-21)The quality of university education has never been more important. Academics and university administrators have paid significant attention to create the conditions that assure the quality of higher education. Measuring ...
-
(2021-04-29)Microstructure of a material determines the transport, chemical and mechanical properties. Geological materials and geomaterials are imaged using microscopy tools. The microscopy images are analyzed to better understand ...
-
(2017-11-03)The Marcellus Shale is the single largest U.S. natural gas resource, both currently and for the foreseeable future. Whereas the Northeast Pennsylvania Marcellus Dry Gas Window produces a significant portion of total Marcellus ...
-
(2023-08-08)When researchers do not have two independent samples with which to cross-validate their instrument, the common advice is to randomly split the sample and conduct the exploratory factor analysis (EFA) on the first half and ...
-
(2019-07-09)The addition of surfactants to completion fluids in ULRs is widely believed to boost productivity and prolong well life. Previous laboratory studies have revealed that this approach is capillary-driven via spontaneous ...
-
(2021-07-09)The purpose of this study was to examine changes in students’ school belonging and behavioral engagement across the transitions to middle school and high school in an academically at-risk population. Growth curve modeling ...

(2016-08-10)A significant portion of America’s youth is overweight or obese. Bully victimization and psychological maladjustment disproportionally afflict this population; however, it is unknown how these factors are related to each ...
-
(2011-02-22)Evaluating the ability of biosorbents to remove arsenic from water has global significance due to the widespread availability and low cost of biosorbent materials. In this study, the ability of coffee grounds and coconut ...
-
(2022-07-07)An abstruse mode of deformation, widely referred to as kink-banding, has been observed over a wide range of length-scales, loading conditions, and in a wide variety of materials across the physical and engineering sciences. ...
-
(2021-07-26)The overarching goal of this dissertation is to quantify the microstructural influence on deformation, degradation, and fracture of some of the most technologically sought after advanced structural materials. In the first ...
-
(Texas A&M University, 2004-11-15)A spectral element algorithm for solution of the incompressible Navier-Stokes and heat transfer equations is developed, with an emphasis on extending the classical conforming Galerkin formulations to nonconforming spectral ...
-
(2023-06-15)This study examined the underlying mechanisms between social networking site (SNS) addiction and suicidal ideation (SI). Despite an emerging literature base providing empirical evidence of a link between problematic SNS ...

Study of an Ionic Liquid as a Corrosion Inhibitor for Pipelines Under a Carbon Dioxide Environment (2020-04-13)In the oil and gas industry, carbon dioxide (CO₂) corrosion is a well-known issue, causing general corrosion and localized corrosion. CO₂ can be dissolved in the aqueous phase, forming carbonic acid (H₂CO₃). This can be ...
-
(2022-07-29)Clostridioides difficile is a Gram-positive, obligately anaerobic microorganism that is of considerable medical concern as a nosocomial and community-acquired human pathogen. C. difficile is an endospore-forming organism ...
-
(2020-02-20)Educational researchers frequently work with data measured as multilevel structures; sometimes, they are also interested in latent constructs that cannot be directly observed and measured. Therefore, handling data dependency ...
