Stories of digital lives: Teacher-student relationships in secondary classrooms and digital spaces
(2012-05)
Scope and Method of Study: This qualitative teacher research study employed narrative inquiry to answer its primary research question: How do secondary teachers and students make connections using digital online media? ...
Estimation of Surrogate Respiration and Detection of Sleep Apnea Events from Dynamic Data Mining of Multiple Cardiorespiratory Sensors
(Oklahoma State University, 2012-07-01)
This research investigates an approach to derive respiration waveform from heart sound signals, and compare the waveform signal obtained thus with those obtained from alternative methods for deriving respiration waveforms ...
Starter Fertilizer Management for Corn and Soybean in the Southern Plains
(Oklahoma State University, 2012-12-01)
Early plant growth and grain yield may be depressed in no-till cropping systems compared to conventional tillage because of the poor nutrient availability early in the growing season. Oklahoma no-till corn (Zea mays L.) ...
Effects of Selenium Supplementation and Chronic Inflammation on Bone Microarchitecture and Strength in Mice
(Oklahoma State University, 2012-07-01)
The effects of dietary Se and lipopolysaccharide (LPS)-induced inflammation on microarchitecture and strength of bone were investigated in C57BL/6 mice. Timed-pregnant mice were fed a Torula yeast selenium-depletion diet ...
Effects of Patch Mosaic Burning on Tick Burden on Cattle, Tick Survival, and Tick Abundance
(Oklahoma State University, 2012-07-01)
Patch mosaic burning (PMB) is a regimen that applies spatially discrete fires with different burning intervals. Along with focal grazing of ruminants, these disturbances create a shifting mosaic of vegetation. Variation ...
Spatial Distribution of Cells Within Void Volume of a Chitosan-collagen Scaffold
(Oklahoma State University, 2012-07-01)
In tissue engineering, cells must be uniformly distributed within 3D scaffolds in order to receive adequate nutrition and oxygen. The objective of this project is to test a novel method to seed cells within a three-dimensional ...
Spark Plasma Sintering of Silicon Carbide, Multi-walled Carbon Nanotube and Graphene Reinforced Zirconium Diboride Ceramic Composite
(Oklahoma State University, 2012-07-01)
Space vehicles re-entering the earth's atmosphere experience very high temperatures due to aerodynamic heating. Ultra-high temperature ceramics (UHTC) with melting point higher than 3200C are promising materials for thermal ...
Employee satisfaction from a generational and gender perspective in the Puerto Rico lodging industry: An exploratory study
(2012-12)
Through this study, the author examined the perceived job satisfaction among hotel-line employees in Puerto Rico to determine whether differences or similarities exist by generational cohorts and gender. This exploratory ...
Infant recognition memory and physical growth in Wolayita: Relations to maternal depression, food insecurity, social support, and mother-infant interaction
(2012-12)
Scope and Method of Study: The purpose of the study was to assess relations of maternal depression (Edinburgh Postnatal Depression Scale, EPDS), food insecurity, social support, maternal nutrition status (BMI), maternal ...
Coal fired power plant water chemistry issues: Amine selection at supercritical conditions and sodium leaching from ion exchange mixed beds
(2012-05)
Scope and Method of Study: This study evaluated thermal degradation kinetics of neutralizing amines in steam cycle coal fired power plants operating supercritical conditions as functions of temperature and pressure. The ...
