SRV REGULATION OF STREPTOCOCCAL BIOFILM DISPERSAL AND ITS IMPACT ON VIRULENCE
Group A Streptococcus (GAS) is a Gram-positive human pathogen that commonly causes mild skin infections. However, GAS also causes severe infections including necrotizing fasciitis. The mechanism for triggering the switch between mild and severe disease has yet to be discovered. Several groups have …

The Hidden Roots of Neoliberal Success in Agrarian Transformation: State Engagement, Farmer Professionalization, and Technological Interdependence in the Senegal River Valley
… irrigated rice in the Senegal River Valley (SRV) as a success story. This is remarkable considering the SRV’s history of agrarian transformation, which critics characterize as incoherent, erratic, and self-destructive. How did this turnaround happen? How did good seeds emerge from bad soil? …

An analysis of defibrillation and cardiac resynchronization therapy strategies in patients with failing systemic right ventricles
… presenting with systemic right ventricular (sRV) dysfunction and at risk of sudden cardiac death (SCD). All patients ( mean age 25 years, range 18-35) with varying functional disability{New York Heart Association (NYHA) II-III} receiving ICDs ± concomitant CRT were evaluated. Total follow-up …

Advanced Electron-Beam Techniques for Solar Cell Characterization
… to measure surface recombination velocity (SRV) for solar cells with different surface passivation conditions. A three-dimensional Monte Carlo simulation for electron-beam sample interaction was first employed to create a three-dimensional carrier generation profile for accurate modelling of …

Mechanisms of fracture complexity and topology of fracture systems induced by hydraulic fracturing
Stimulated reservoir volume (SRV) is a prime factor controlling well performance in unconventional shale plays. In general, SRV describes the topology of induced fractures by hydraulic fracturing. Natural fractures (NFs), such as joints and faults, are ubiquitous in oil and gas reservoirs, where …

Phylogenetics and New Approaches to Vaccine Development for West Nile
… VSV expressing the Simian Retrovirus-2 (SRV-2) gag and Env gene constructs and the Herpes B virus glycoprotein D gene were constructed and characterized in cell culture experiments. The VSV-SRV-2 gag and env recombinants generated protective immune responses in non-human primates. The VSV …

An integrated peridynamics-finite volume based multi-phase flow, geomechanics and hydraulic fracture model
… the extent of the Stimulated Reservoir Volume (SRV) around a primary hydraulic fracture is developed. A sensitivity study for the effects of elastic properties of the formation, injection rate, and the reservoir fluid type on SRV extent is presented

Modelling of freeze layer formation and refractory wear in direct smelting process
… the HIsmelt pilot plant Smelt Reduction Vessel (SRV) has been modelled for the period of campaign 8-1 & 8-2 (just over 20 days). The predicted wear is in agreement with the measurements taken after the vessel had been cooled. To bring together freeze layer formation with the refractory wear …

Machine learning of molecular conformations, kinetics and beyond
… model termed “State-free Reversible VAMPnets” (SRVs) to learn slow CVs that govern the dominant kinetics of the system. By comparing SRVs with the existing kernel based method, I show that SRVs are more accurate, less sensitive to feature selection and feature scaling, and more computationally …

PRODUCTION FORECASTING FOR SHALE OIL: WORKFLOW
… wells is called the Stimulated Reservoir Volume (SRV) Bounded Model by the software marketer Kappa. We tested this and other models using a Beta test version of new Kappa software. While accurate, this modeling approach is too time consuming for routine use. We found that a simple empirical …

Uncertainty quantification of unconventional reservoirs using assisted history matching methods
… fracture groups; and stimulated rock volume (SRV) around fracture groups. The method is developed in a sleek, stand-alone form and is composed of four main steps: (1) reading parameters exported by tool; (2) generating an EDFM instance; (3) running the instance on a simulator; and (4) …

Surface and bulk passivation of multicrystalline silicon solar cells by silicon nitride (H) layer : modeling and experiments
… dependence of surface recombination velocity (SRV), which is in contradiction to experimental results. An alternative approach is needed to address this problem. A modified SRH formalism which includes the carrier recombination in the space-charge region was developed in this thesis to evaluate …

Model for a Shale Gas Formation with Salt-Sealed Natural Fractures
There are reported cases of hydraulically fractured shale wells that exhibit boundary dominated flow in a very short period. This study suggests that dissolution of salt-sealed natural fractures in the shale offers a novel explanation for the early boundary dominated flow. We first discuss a …
