Surface polishing of niobium for superconducting radio frequency (SRF) cavity application
… based on superconducting radio frequency (SRF) technology. The interior of SRF cavities are cleaned and polished in order to produce high accelerating field and low power dissipation on the cavity wall. Current polishing methods, buffered chemical polishing (BCP) and electropolishing (EP), …

Thin Film Approaches to The Srf Cavity Problem: Fabrication and Characterization of Superconducting Thin Films
Superconducting Radio Frequency (SRF) cavities are responsible for the acceleration of charged particles to relativistic velocities in most modern linear accelerators, such as those employed at high-energy research facilities like Thomas Jefferson National Laboratory’s CEBAF and the LHC at CERN. …

Serum Response Factor Regulates Multiple Aspects of Central Nervous System Development
SRF is a highly evolutionary conserved activity-dependent transcription factor. Previous studies have shown that neuron-specific deletion of SRF results in deficits in tangential cell migration, guidance-dependent circuit assembly, activity-dependent gene expression, and synaptic plasticity in the …

Short Rotation Forestry and Earthworm Diversity: Impacts and Responses
Short Rotation Forestry (SRF) has been introduced to the UK as a method to increase biomass production. However, some SRF species have raised concerns about potential impacts on the environment. A largely unknown aspect of SRF is the quality and quantity of leaf litter, and its impact on soil …

Overexpression of Serum Response Factor in Astrocytes Improves Neuronal Plasticity in a Model of Fetal Alcohol Spectrum Disorders
… protein (CREB) and the Serum response factor (SRF). SRF is important for many plasticity processes such as LTP, LTD, spine motility and axonal pathfinding. Here we attempt to rescue OD plasticity in alcohol-treated ferrets using a Sindbis viral vector to express a constitutively active form of …

Serum response factor-dependent regulation of smooth muscle gene transcription
… one. Serum response factor (SRF) is the major transcription factor that plays an essential role in coordinating a variety of transcriptional events during this phenotypic change. The first goal of my thesis studies is to determine how SRF regulates the expression of smooth …

Spontaneous Rosette Formation In Mice Immunized With Listeria Monocytogenes
… upon spontaneous rosette formation (SRF) between BALB/c mouse spleen lymphocytes and C57BL mouse erythrocytes. It was found that SRF in nonimmunized mice ranged from 8 to 20 percent with a mean value of 12.0 + 2.1 percent. Immunofluorescence studies indicated that 40.7 ± 7.65 percent …

Investigating the Role of Hippo/Warts Signaling in Sarcomatoid Renal Cell Carcinoma
… reveals an enrichment of serum response factor (Srf) targets amongst genes upregulated following Lats1/2 deletion. Ablating Srf in the Lats mutant background causes Lats;Srf mutant cells to undergo epithelial to mesenchymal transition but not progress to fulminant tumors in vivo. RNA-sequencing, …

Modelling and characterisation of the pyrolysis of secondary refuse fuel briquettes and biomass materials
… pyrolytic behaviour of secondary refuse fuel (SRF) briquettes and biomass-derived fuels is the starting point for the process. The purpose of this study was to evaluate the pyrolytic characteristics of SRF briquettes and biomass materials, suggest a kinetic model for simulating the pyrolytic …

Objective and subjective personality characteristics of medical students
… instrument, the Subjective Rating Form (SRF), were utilized in this study. Significant differences were found in 16PF scores from entry to medical school (Time 1) to exit from medical school (Time 2). Significant differences were also observed when SRF scores were compared between Self at …

Plasma Processing of Superconducting Radio Frequency Cavities
… technology of superconducting radio frequency (SRF) cavities not only provides a chemical free and less expensive processing method, but also opens up the possibility for controlled modification of the inner surfaces of the cavity for better superconducting properties. The research was focused …

Trace Level Impurity Quantitation and the Reduction of Calibration Uncertainty for Secondary Ion Mass Spectrometry Analysis of Niobium Superconducting Radio Frequency Materials
… for enabling superconducting radiofrequency (SRF) cavities to operate more efficiently at high accelerating gradients. The discovery of "nitrogen doping" was the first readily accessible avenue of interstitial alloying in which researchers saw an increase in cavity performance. However, the …

Roles of Myocardin-Related Transcription Factors in Muscle and Brain
… the partnership between Serum response Factor (SRF) and its Myocardin Related Transcription Factor (MRTF) coactivators during development. I present here my studies on the functions of MRTFs during brain and muscle development. First, I show that MRTF-A and -B redundantly control neuronal …

Serum Regulation of Inhibitor of DNA Binding/Differentiation 1 Expression by a BMP Pathway and BMP Responsive El
… promoters, which bind Serum Response Factor (SRF). However, many other IEGs do not have SREs in their promoters and their serum regulation is poorly understood. We have identified SRF-independent IEGs in SRF-depleted fibroblasts. One of these, Id1, was examined more closely. We mapped a serum …
