Upgrading natural gas to value-added liquid products in aqueous systems under ambient conditions
(Wichita State University, 2017-07)A novel method of upgrading natural gas into value-added liquid products is presented, in which the methane is activated by a decoupled oxidation approach with metal-surface facilitation in aqueous system under ambient ... -
Upper Jurassic microbolite buildups in the little cedar creek and Brooklyn fields in SW Alabama
(Wichita State University, 2014-05)This study investigates the stratal relationships of a pure microbolite within the Upper Jurassic strata at the Little Cedar Creek, and Brooklyn Fields, or complex, for the development of a refined exploration model of ... -
Urania for orchestra
(Wichita State University, 2015-07)Urania is a work that is loosely modelled on early Greek music theory (Urania was one of the nine muses worshipped by ancient Greeks), namely the idea of creating scale structures from inserting two variable notes in ... -
Use of SPH and Lagrangian meshing technique to assess damage area in bumper shields impacted by hypervelocity space debris
(2007-05)Space debris are objects in Earth’s orbit consisting of fragments of spent rocket stages, non-functional satellites, and parts like fasteners, paint chips and other waste materials in the lower earth orbits (LEO) (200 – ... -
The use of video to facilitate parent empowerment in early intervention
(Wichita State University, 2009-05)This quasi-experimental study piloted a video that was designed to increase parent empowerment. Participants were parents of children ages 0-3 with special needs who had recently qualified for early intervention services. ... -
User selection with perfect and no primary CSIT in MIMO cognitive radio networks
(Wichita State University, 2014-12)Spectrum is one of the most precious resources in the field of wireless communication field. As the number of users and demand for fast data transmission increases, the current spectrum resources become insufficient. ... -
Using a value stream map to assess environmental impacts
(Wichita State University, 2009-12)In today's competitive world, companies focus on eliminating wastes to increase their profit, growth and ensure customer satisfaction. Among the known wastes, environmental wastes are typically the least considered. ... -
Using appreciative inquiry to describe and create teacher peak experiences: a case study of elementary school teachers
(2007-05)The purpose of this study was to describe the peak experiences of teachers while teaching and the necessary ecological conditions for them to enter into a peak experience state. Due to limited research on the study of peak ... -
Using energy dispersive X-ray fluorescence (ED-XRF) to assess the stratigraphic relationships of the middle Jurassic Gypsum Spring and Piper formations, Bighorn Basin, Wyoming and Montana
(Wichita State University, 2015-05)Chemostratigraphy via X-ray fluorescence measures the shifts in elemental properties within a given section of strata. It has proven to be a successful tool in both correlation and paleo-environment reconstruction. Recently, ... -
Using fuzzy signal detection theory to assess the impact of text messaging on drivers' hazard perception ability
(Wichita State University, 2015-05)Hazard perception is a multi-faceted process that requires drivers to maintain an ongoing awareness of a complex driving environment. The majority of research studies, however, utilize behavioral responses to a limited ... -
Using ion mobility spectrometry to resolve isotopomers, identify isomers by isotopologic shifts, and predict mobility changes for post-translationally modified peptides
(Wichita State University, 2017-05)Differential or field asymmetric waveform ion mobility spectrometry (FAIMS) operating at high electric fields fully resolves isotopic isomers for a peptide with labeled residues. The naturally present isotopes, alone and ... -
Using surfactant-based colloidal systems to promote photoinduced synthesis of silver nanoparticles
(Wichita State University, 2018-07)This thesis focuses on the photo-initiated synthesis of silver nanoparticles in water with low concentration of stabilizing agents to investigate the role that surfactants, specifically their charge, plays in the synthesis. ... -
Using technology to prepare for future scienTESTS
(2006-07)This research studied the impact of technology integration during science lessons to help prepare fourth graders in a suburban elementary school for the Kansas State Science Assessment. The three instructional methods ... -
Validation of balance assessment measures of an accelerometric mobile device application versus a balance platform
(Wichita State University, 2012-05)Recent technological advancements in electronics and telecommunications have provided more accessible quantitative methods of assessing balance. The latest smartphones have built-in motion sensors called tri-axial ... -
Variation in demography and effect of insect herbivory on Platte thistle (Cirsium canescens) between biogeographic range center and range edge
(Wichita State University, 2020-12)Insect herbivory can reduce plant fitness, but the strength of these effects varies greatly in space and time. The Abundant Center Hypothesis (ACH) states that species will encounter more stressful abiotic conditions at ... -
Various predictors of risky sexual behavior in adolescence
(Wichita State University, 2016-05)Sexuality is a pivotal stage in adolescent development. Adolescents may engage in risky sexual behaviors (RSBs): early sexual initiation, multiple and non-monogamous relationships, contraception inconsistency, and greater ... -
Verbs used by persons with aphasia during procedural discourse
(Wichita State University, 2020-05)The purpose of this study was to determine if people with mild-moderate non-fluent aphasia use verbs that differ in quantity and quality during procedural discourse than they do during conversational discourse, as well ... -
