Abstract

Full-scale simulations of a Gulfstream G-III aircraft, performed in support of the NASA Acoustic Research Measurements flights, are presented to complement results discussed in earlier studies. The flow solver employed in those studies, Dassault Systèmes’ lattice Boltzmann PowerFLOW®, was also used during this investigation to conduct time-dependent simulations of the entire aircraft in landing configuration with a fully dressed landing gear. The high-fidelity simulations, performed at a Mach number of 0.23 and a Reynolds number of 10.5 × 106 based on mean aerodynamic chord, captured all relevant airframe noise sources. The computations were used to assess the aeroacoustic performance of the main landing gear, with and without noise reduction fairings installed, of a G-III aircraft equipped with Adaptive Compliant Trailing Edge technology and conventional Fowler flaps. To facilitate comparison of predicted noise signatures with effective perceived noise levels obtained from flight test measurements, the “as-flown” nose landing gear geometry, missing in our earlier studies, was added to the simulated G-III aircraft configurations. The high fidelity, synthetic data were post-processed using a Ffowcs-Williams and Hawkings integral approach to estimate farfield acoustic behavior, with pressures on the model solid surface or pressure and velocity components on a permeable surface enveloping the acoustic near field used as input.

Abstract

Microphone phased-array and pole-mounted microphone data gathered during the NASA Acoustics Research Measurements flight tests were used to benchmark results from companion full-scale aeroacoustics simulations. Conducted with the lattice Boltzmann solver PowerFLOW®, the simulations predicted the acoustic behavior of various tested aircraft configurations. Emphasis was placed on those flown during the third flight test - a Fowler flap-equipped Gulfstream G-III with and without noise abatement technology on the main landing gear. Direct comparisons between experimental and synthetic microphone phasedarray data were achieved by applying the same processing and deconvolution technique to both sets of data. To extend the validation of the computations to the metric used for noise certification, the Effective Perceived Noise Level, a high-fidelity digital model of the nose landing gear, which was excluded from earlier computations, was developed and integrated into the G-III aircraft geometry. The acoustic study presented here demonstrates that the simulated beamform maps and corresponding integrated farfield spectra accurately predict the locations and strengths of the prominent airframe noise sources present on the G-III aircraft.

Abstract

Computational results are presented for a high-fidelity, full-scale, full-span Gulfstream G-III aircraft model equipped with flap and main landing gear (MLG) noise reduction technologies. The simulations, which were conducted in support of a NASA airframe noise flight test campaign of the same technologies, use the lattice Boltzmann solver PowerFLOW® to capture time-accurate flow data with sound propagation to the far field accomplished using a Ffowcs-Williams and Hawkings (FWH) acoustic analogy approach. The aerodynamic and aeroacoustic behavior of the aircraft were investigated in the approach configuration with combinations of flap and landing gear deployments. The simulated flap concept is an Adaptive Compliant Trailing Edge (ACTE) flap that replaces the Fowler flap system on the G-III aircraft. The simulated MLG noise reduction concept is comprised of porous fairings and a collection of other smaller fairings fitted around the flow-facing components. Using the Fowler flap results as a reference, comparisons are presented on the noise reduction effectiveness of the ACTE flap system. Investigations were made on the effects of using the porous fairings and ACTE flap as noise reduction concepts in tandem. The ACTE flap was found to reduce the total airframe noise level at all flap deflection angles when compared to the Fowler flap equipped model. As anticipated, a reduction in aerodynamic performance was also found when the ACTE flap system was used. The MLG fairings were shown to further reduce the total airframe noise level of the G-III.

Abstract

Background: Little is known about antibiotic prescribing on hospice admission despite known risks and limited evidence for potential benefits. Objective: To describe the frequency and characteristics of patients prescribed antibiotics on hospice admission. Design: Cross-sectional study. Subjects: Adult (age ≥18 years) decedents of a national, for-profit hospice chain across 19 U.S. states who died between January 1, 2017 and December 31, 2019. Measures: The primary outcome was having an antibiotic prescription on hospice admission. Patient characteristics of interest were demographics, hospice referral location, hospice care location, census region, primary diagnosis, and infectious diagnoses on admission. We used multivariable logistic regression to quantify associations between study variables. Results: Among 66,006 hospice decedents, 6080 (9.2%) had an antibiotic prescription on hospice admission. Fluoroquinolones (22%) were the most frequently prescribed antibiotic class. Patients more likely to have an antibiotic prescription on hospice admission included those referred to hospice care from the hospital (adjusted odds ratio [aOR] 1.13, 95% confidence interval [CI] 1.00–1.29) compared with an assisted living facility, those receiving hospice care in a private home (aOR 3.85, 95% CI 3.50–4.24), nursing home (aOR 3.65, 95% CI 3.24–4.11), assisted living facility (aOR 4.04, 95% CI 3.51–4.64), or hospital (aOR 2.43, 95% CI 2.18–2.71) compared with inpatient hospice, and those with a primary diagnosis of liver disease (aOR 2.23, 95% CI 1.82–2.74) or human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (aOR 3.89, 95% CI 2.27–6.66) compared with those without these diagnoses. Conclusions: Approximately 9% of hospice patients had an antibiotic prescription on hospice admission. Patients referred to hospice from a hospital, those receiving care in a noninpatient hospice facility, and those with liver disease or HIV/AIDS were more likely to have an antibiotic prescription. These results may inform future antimicrobial stewardship interventions among patients transitioning to hospice care. [ABSTRACT FROM AUTHOR]

Abstract

Background: Granulosa cell tumours (GCT) are the most common ovarian tumours in mares. While the classical presentation may not represent diagnostic challenges, diagnosis is not easy in the early stages. Objectives: Illustrate the variability in the presentation and serum biomarkers associated with ovarian abnormalities in the mare. Study design: Retrospective case series. Methods: Nonclassical cases of GCTs and other ovarian conditions were identified and behaviour, GCT endocrine results, palpation and ultrasonographic findings are described and the diagnostic value of each is discussed. Results: Mares in this case series with GCTs had been presenting clinical signs ranging from no behavioural changes to behaviours including aggression, stallion‐like and inability to work under saddle. Hormonal profiles of endocrinologically functional GCTs can be erratic and unpredictable. The clinical form and ultrasonographic appearance may also vary with time from an initially enlarged/anovulatory follicular structure that later develops a multicystic 'honeycomb' appearance. Mares with GCTs can also present with persistent anovulatory follicles or apparent luteal tissue that are unresponsive to treatment. If both ovaries are of relatively normal size and symmetry, but hormonal biomarkers are markedly increased (AMH >10 ng/mL, inhibin B and/or testosterone >100 pg/mL; 0.37 nmol/L), it is likely that a functional GCT is present. Still, it can be a challenge to decide which ovary to remove. Post‐surgical endocrine testing can be helpful, especially if histopathology is not performed or a GCT is not found. Main limitations: Cases limited to 14. Conclusions: Granulosa cell tumours present with a wide variety of clinical signs that do not fit what is commonly described as 'classic'. Only if AMH, testosterone and inhibin B concentrations are markedly increased, and there is an abnormally enlarged ovary, the diagnosis of a GCT is more confident. In the presence of normal size ovaries, normal hormonal biomarkers and abnormal behaviour, it is more likely that the ovaries are not involved. [ABSTRACT FROM AUTHOR]
