Functional Analysis of Two NAC Transcription Factors and Transcriptome Analysis under Drought in Citrullus Colocynthis
(2014-04-23)
Citrullus colocynthis (L.) Schrad, closely related to watermelon (Citrullus lanatus L.), belongs to the Cucurbitaceae family. It can survive arid environments by maintaining its water content without wilting of the leaves ...
Univariate and Dynamic Multivariate Analysis of Functional MRI Data
(2014-04-23)
Functional magnetic resonance imaging (fMRI) has been increasingly used in the past decade for inferring brain function in both healthy and clinical populations. In this dissertation, we demonstrate fMRI data analysis ...
Cardioprotective mechanisms of PPAR gamma in diabetic heart
(2014-04-23)
Patients with diabetes exhibit significantly altered renin-angiotensin system (RAS). Recently it has been determined that hyperglycemic conditions induce an increase in angiotensin II (AT II) expression; specifically in ...
The Efficiency of Enzymatic L-Cysteine Oxidation in Mammalian Systems Derives from the Optimal Organization of the Active Site of Cysteine Dioxygenase
(2014-04-22)
Intracellular concentrations of free cysteine in mammalian organisms are maintained within a healthy equilibrium by the mononuclear iron-dependent enzyme, cysteine dioxygenase (CDO). CDO catalyzes the oxidation of L-cysteine ...
Hemichordate phylogeny: a molecular and genomic approach
(2014-04-17)
The phylogenetic relationships within Hemichordata are significant for understanding the evolution of the deuterostomes. Hemichordates possess several important morphological structures in common with chordates, and they ...
Liquid Phase Desulfurization of Hydrocarbon Fuels under Ambient Conditions using Regenerable Mixed Oxide Supported Silver Adsorbents
(2014-04-09)
Sulfur derivatives are major contaminants in hydrocarbon fuels. Sulfur emission from fuel is a major environmental concern and many countries around the world are enacting laws to limit it. In addition, the development of ...
Impacting the bottom line: Behavior mapping in a full-service hotel kitchen
(2014-04-08)
The study at hand sought to demonstrate the value of spatial layout and functionality in the
foodservice industry and the impact these components have on productivity, employee
satisfaction, and ultimately the bottom ...
Disturbance in the anchialine ecosystem: ramifications for ecology and physiology
(2014-04-07)
Habitats in the anchialine ecosystem are defined as coastal ponds, pools, and caves that lack surface connections to the open ocean, but possess both seawater and freshwater influences due to subterranean connections to ...
Turbine Aerothermal Optimization Using Evolution Strategies
(2014-04-07)
The use of adaptive optimizers in turbine blade geometry design is discussed. Many different adaptive optimizers have been applied to turbine blade design in the past, but often the optimizer does not fit the problem and ...
Relay Positioning for Energy Efficiency and Improved Performance of Cooperative Wireless Networks
(2014-03-31)
Cooperative communications in wireless networks have gained much interest due to their
ability to mitigate the effect of fading in wireless networks by achieving spatial diversity. One
of the techniques used in cooperative ...
Power Control for Underlay Cognitive Radio Networks with Full-duplex Transmissions
(2014-03-31)
Radio communication, one of core contents in wireless communication, is facing a great crisis of running out of resource. Unlike other energy crisis which can be solved by using all kinds of alternative energy, the only ...
Brand Equity among Producers of Chinese Mitten Crab
(2014-03-31)
In the Shanghai area of China there is considerable product differentiation among producers of Chinese mitten crab Eriocheir sinensis, with as many as 50 brands available in the marketplace. At the same time, the brand ...
The Synthesis and Tunable Processing of Metallic and Magnetic Nanoparticles in a Functional Solvent System
(2014-03-31)
The concepts presented in this dissertation describe techniques that have been developed to produce metallic and magnetic nanoparticles using dimethyl sulfoxide (DMSO). The unique and size-dependent properties of nanoparticles ...
Molecular Dynamics Simulations of Dry Sliding Asperities to Study Friction and Frictional Energy Dissipation
(2014-03-31)
Fundamental friction characteristics such as the friction coefficient, wear, adhesion, and dissipation of energy require an accurate understanding of how the surfaces in contact interact on nano or atomic scale. At nano ...
Land: Water Surface Area Ratio for Aquaculture Ponds
(2014-03-31)
Aquaculture farms use more land than the pond water surface area because of the necessity for embankments, canals, roads, storage areas, offices, parking lots, and staging areas. Aquaculture farms with different-sized ...
Resource Allocation and Performance Optimization in Wireless Networks
(2014-03-31)
In the past few years, demand has kept increasing for higher data rates in wireless networks due to the increases in the numbers of mobile subscribers and multimedia applications. Femtocell and free space optics(FSO) ...
Training Parents to Enhance Social Skills in Children with Developmental Delays: A Component Analysis
(2014-03-31)
Social skills deficits are a core feature of ASD (American Psychiatric Association [APA], 2000; Parsons & Mitchell, 2002), and they are related to a myriad of other social, developmental, and psychological challenges ...
Steady State and Transient Response Characteristics of Commercial Non-Dispersive Infrared Carbon Dioxide Sensors
(2014-03-31)
Non-dispersive infrared CO2 sensors are well established and are commonly used
to provide demand control ventilation for commercial buildings. The aviation industry
