A retrospective review of outcomes in patients with node-negative stage IB cervical cancer treated with adjuvant standard pelvic field radiation versus small field pelvic field radiation
… or with reduced-size, "small pelvic field" (SPF) RT since 1991. These two methods reflect changes in protocol over the period of this review. Cisplatin given concurrently with radiation has been used since 1999. Cancer control and grade 3 and 4 toxicities were compared between the two groups. …

Single and dual experimental infection of specific pathogen-free Litopenaeus vannamei shrimp with White Spot Syndrome Virus and Vibrio species
… The availability of specific pathogen-free (SPF) is now facilitating the development of standardized protocols for pathogen challenge, as established recently for WSSV. Hence, a protocol for Vibrio challenge in SPF shrimp was standardized. Shrimp from postlarve to juvenile were challenged …

An energy and environmental analysis of aerospace sheet metal part manufacturing
… aerospace production, and superplastic forming SPF is used when high formability is required. Machining is used extensively for very low volume production, such as prototyping. We find that the new RAFFT technology is best suited for very low volume production such as the production of …

Friction stir welding of commercially available superplastic aluminium
… microstructure for superplastic Forming (SPF). Therefore the main goal is to produce friction stir welds which do not fail during subsequent SPF processes. The friction stir welds have been created using novel tools which are oversized for the material thickness used; this creates a wider …

Network-aware Multi-agent Reinforcement Learning for Adaptive Navigation of Vehicles in a Dynamic Road Network
… on variants of the popular Shortest Path First (SPF) algorithm to suggest a route, assuming a static network. However, road network conditions are dynamic, rendering the SPF route planning algorithms to perform sub-optimally at times. In addition, SPF is a greedy algorithm. So, while it can yield …

Mechanism of Pathogenesis and Replication of an Avian Strain of the Hepatitis E Virus in a Chicken Model
… to experimentally infect specific-pathogen-free (SPF) adult chickens by the natural fecal-oral route in order to systematically study HEV pathogenesis and replication and to characterize the clinical course and pathological lesions associated with avian HEV infection. Sixty-week-old, …

Flow Between a Cylinder and a Rotating Coaxial Cylinder, Axisymmetric Shaft With Axially-Periodic Radius Variation, or Screw
… computationally. In spiral Poiseuille flow (SPF), where the inner shaft is a circular cylinder, complete linear stability boundaries are determined for a wide range of parameters. The analysis accounts for arbitrary infinitesimal disturbances over the entire range of Reynolds numbers (Re) for …

An Investigation into Nonlinear Random Vibrations based on Wiener Series Theory
… enhance EL known as the Single-Pole Fit method (SPF) is to be tested for different kinds of systems to prove its robustness and validity. Its direct application to systems with nonlinear stiffness and nonlinear damping is shown as well as its ability to perform for systems with two degrees of …

Calibration of the Highway Safety Manual and development of new safety performance functions for rural multilane highways in Kansas
… The HSM-given safety performance function (SPF) regression coefficients were then modified to capture variation in crash prediction. The adjusted models for 4D and 4U multilane segments indicated significant improvement in crash prediction for rural Kansas. Furthermore, Kansas-specific …

A study of the role of friction in superplastic blow forming of alloy sheet
Superplastic forming (SPF) is a manufacturing process whereby certain materials, under specific temperatures and strain rates, exhibit high ductility resulting in large deformations. Superplastic forming has found a wide application in industry, especially in the aerospace sector for the …

Permanent Bracing Design for MPC Wood Roof Truss Webs and Chords
… (S. Pine) braced by 2x4 STUD Spruce-Pine-Fir (SPF). Chord load levels of 10% to 50% of the allowable compression load parallel-to-grain assuming le/d of 16 were studied. All wood-to-wood brace connections were assumed to be made with 2-16d Common nails. A nonlinear load-displacement function …

The Effect of the Microbiome on DNA Methylation
… (GF; no microbiome) and specific pathogen free (SPF; controlled microbiome) mice were analyzed with a DREAM assay. This was done in wild-type mice and in IL-10 KO mice, with or without the addition of the colitis-associated cancer inducing compound, azoxymethane (AOM). We found that individually, …

Epidemiology of Chlamydiaceae in livestock and emerging Chlamydia psittaci infections in chickens
… strains in experimentally (aerosol) infected SPF chickens. Both strains caused conjunctivitis, rhinitis and dyspnoea. Pharyngeal and cloacal C. psittaci excretion was observed in all infected animals, indicative for systemic dissemination as proven by immunofluorescence staining of frozen …

Studying the riboregulatory role of Hfq in Klebsiella pneumoniae using CLASH (crosslinking, ligation and sequencing of hybrids)
… and ABR. I investigated some sRNAs such as Spf, RyhB, and OmrA/B, which interact with genes that modulate β-lactam susceptibility. A significant discovery of my thesis is the phenotype obtained due to the interaction between Spf and mrdA (encodes Penicillin Binding Protein 2). Spf deletion …
