Analysis of Second Grade Bilingual Classroom Observations using the Transitional Bilingual Observation Protocol: Language of Instruction, Language Content, Communication Mode, and Activity Structures
(2017-05-09)
In public education in Texas, administrators, educators, and policymakers struggle with decisions on how to improve overall quality instruction to meet the needs of English language learner (ELL) student populations. ...
Hox DNA Binding: From Monomers to Fibers
(2017-03-23)
Biological macromolecules can bind a wide range of ligands with high affinity and high specificity. In particular, proteins that bind DNA must recognize a particular DNA sequence within a vast array of non-target sites. ...
Novel Polymer Transparent Ultrasound Transducers for Photoacoustic Imaging Applications
(2016-07-14)
Recently, photoacoustic imaging has emerged as a new hybrid biomedical imaging technique, which provides rich optical contrast information at deep ultrasound penetration depth not achievable with conventional optical imaging ...
Factors Affecting Asphaltenes Stability
(2017-05-09)
Asphaltenes represent the heaviest and the most polar fraction of crude oil. Asphaltenes precipitation within the reservoir pores or production flow lines can severely hamper petroleum extraction process. Although the ...
An Experimental Study of the Use of Plasma Actuators for Skin Friction Reduction in Turbulent Boundary Layers
(2016-12-13)
Parasitic drag is a restrictive force for all vehicles moving through a fluid medium. In many industries and applications, even incremental reductions in drag could result in large savings in fuel, time, and even thermal ...
Nonlinear Time-Frequency Control of a High-Speed Spindle Using Active Magnetic Bearings
(2017-04-24)
The objective of this research was to demonstrate the capability of a novel design of a high-speed spindle using combination active magnetic bearings (AMBs) with a nonlinear time-frequency controller. The spindle modeled ...
Comparison of Friction Reduction & Wear Preventive Properties of Soluble & Insoluble Additives in Drilling Mud
(2017-05-10)
In comparison to vertical hole drilling, recent explorations of ERD wells and use of horizontal drilling strings has significantly increased the drag and torque as well as wear on the drill string, drill column, casings ...
A Rational Approach to Design Novel Inhibitors of Mycobacterium tuberculosis Isocitrate Lyases
(2019-01-14)
Isocitrate lyase 1 & 2 are essential enzymes for Mycobacterium tuberculosis pathogenicity and antibiotic resistance, and thereby, are appealing targets for the treatment of latent tuberculosis. Since high-throughput screening ...
Pathogenesis of Chronic Kidney Disease in Dogs with X-linked Hereditary Nephropathy
(2019-01-11)
Chronic kidney disease (CKD) is a common cause of morbidity and mortality in dogs that, by the time diagnosis occurs using traditional biomarkers, significant damage to the kidneys has occurred. Therefore, establishment ...
Removal Efficiency, Cleanup Mechanism, and Damage Analysis of a Novel Treatment for Oil-Based Drilling Fluid Filter Cake Removal
(2019-02-27)
Removing oil-based drilling fluid (OBDF) filter cake is a difficult task. Low removal efficiency of filter cake may result in pay zone damage, including drilling fluid filtrate incompatibilities with reservoir fluids, fines ...
