A remedial approach to stabilize a deep excavation in Singapore
Ground improvement methods are commonly adopted in deep excavation to minimize wall deflection, wall bending moment and strut force. In this thesis a different approach to the application of ground improvement techniques is analyzed in the form of a parametric study developed with the use of a …

A universal approach to stabilize water-oil interface via surfactant self-assembly
Liquid-liquid interfaces represent an advantageous setting for the confinement, manipulation, and controlled assembly of colloids. Stabilizing liquid-liquid interfaces, whether between miscible or immiscible liquids, is crucial for a wide range of applications, including energy storage, …

Non-coding RNA genes lost in Prader-Willi Syndrome stabilize target RNAs
Prader-Willi Syndrome (PWS) is a genetic disease that results in abnormal hormone levels, developmental delay, intellectual disability, hypogonadism, and excessive appetite. The disease is caused by a de novo genetic deletion in chromosome 15. While many of the deleted genes have been identified, …

Rethinking homeownership : why alternative tenure strategies are needed to stabilize neighborhoods in Lawrence, MA
… and policy approaches are needed in order to stabilize distressed neighborhoods and improve quality of living? Consistent with Lawrence's growing challenge with foreclosures and research on low-income homeownership, the findings of this thesis demonstrate that focusing on homeownership …

How to utilize hedging and a fuel surcharge program to stabilize the cost of fuel
… utilize hedging and a fuel surcharge program to stabilize the cost of fuel? The survey showed the wide adoption of fuel surcharges, confirming the academic research. The sensitivity test proved the need to keep the escalator variable in line with a carrier's actual fuel efficiency and standardize …

Electrical and Optogenetic Stimulation of Sympathetic Neurons to Stabilize Blood Pressure after Acute Spinal Cord Injury
… following acute SCI, and that eSTIM can stabilize blood pressure and prevent blood pressure drop during orthostatic challenge in acutely injured mice. I developed a method to stimulate deeper neurons in the spinal cord hemodynamic hotspot using optogenetics and showed that the optogenetic …

Investigating the feasibility of implementing microbially induced calcite precipitation to stabilize sand, clay and gold tailings
Microbially Induced Calcite Precipitation (MICP) is an emerging bio-mediated technology which has been successfully applied in soil improvement research. MICP uses the enzyme urease produced from bacteria to breakdown urea into carbonate ions. These carbonate ions combine with free calcium ions to …

Sindbis virus usurps the cellular HUR protein to stabilize its transcripts and promote infections of mammalian and mosquito cells
Members of the genus Alphavirus are recognized as significant human pathogens. Infection of vertebrate hosts often results in febrile illness and occasionally severe encephalitis. The archetypical alphavirus is Sindbis virus, which we have utilized in these studies. The genomic and subgenomic RNAs …

A Study of Dynamics and Stability of Two-Craft Coulomb Tether Formations
… forces. A charge feedback law is introduced to stabilize the relative distance between the satellites to a constant value. Compared to previous Coulomb thrusting research, this is the first feedback control law that stabilizes a particular formation shape. The two craft are connected by an …

State Feedback Control of a Single-Loop Thermosyphon System Via a Quotient Controller
… this work is to design a quotient controller to stabilize a chaotic flow in a single loop thermosyphon system with a high heat index. The thermosyphon loop is heated from below and cooled from above, which causes time-dependent chaotic flow when the external heat index is above a threshold value. …

Stabilization of liposomal functional anchors by cross-linkable lipids
… of serum. Here we investigate a method to stabilize a class of liposomes in which lipid vesicles are modified post- fabrication through surface adsorption and anchoring. We hypothesized that the sequential adsorption of functional units followed by covalent cross-linking of the liposome …

Robust low-order control of flexible joint manipulators
… to design a robust state feedback controller to stabilize the linear system and to give a specified bound on the disturbance rejection of the closed-loop system with enough robustness margin as to stabilize the actual nonlinear model.
