Trout Fishing in the Smokies and the Blue Ridge, 1880-Present: How-To, History, and Habitat
This study focuses on trout fishing in the Great Smoky Mountains and the Blue Ridge Mountains from 1880 to 2017. I begin with a collection of personal narratives of fly-fishing in Tennessee to portray the allure of southern Appalachia trout fishing. I then describe the transition from native Cherokee fishing practices to sport fishing in the Smokies and the Blue Ridge by 1880. I explore a brief history of the National Parks and the United States Forest Service during the early 1900s, and address European fly-fishing influences in the United States during the twentieth century. I examine the habitats of the rainbow trout (oncorhynchus mykiss) and the native brook trout (salvelinus fontinalis) to provide an analysis on inter-species relationship between rainbow and brook trout in mountain streams. I then give an overview of important trout literature in the Smokies and the Blue Ridge through the twentieth and twenty-first centuries

Direct Numerical Simulation of Acoustic Disturbances in a Hypersonic Two-Dimensional Nozzle Configuration
Direct numerical simulations (DNS) are performed to study acoustic radiation in a quasi-two-dimensional nozzle with two independents spatially evolving turbulent boundary layers with an edge Mach number of 6. The emphasis of this work is to compare the radiated pressure fluctuations in a geometrically confined environment with those radiated from a single wall in an unconfined setting. The boundary-layer profile of the rms pressure fluctuation scaled by the mean shear stress at the wall is found to be in good agreement with prior flat-plate calculations at similar conditions. However, the normalized rms pressure fluctuation within the freestream p region is significantly higher than that in the unconfined case, by a factor that is approximately equal to 2. The application of two different compressibility transformations to the computed mean velocity profiles indicates that, in comparison with the van Driest transformation, the Trettel and Larsson transformation provides a better collapse with flat-plate simulations over a broad range of Mach numbers. The DNS data also reveal that, in spite of displaying a strongly non-Gaussian behavior inside the boundary layer, the radiated acoustic fluctuations in all thermodynamic variables have a skewness of approximately 0.3, indicating a minor deviation with respect to Gaussian behavior. Surface pressure fluctuations along the nozzle walls are not significantly impacted by the acoustic waves radiating from the opposite wall
Skilled Labor Shortages May Lead to Wage Inflation
In Boise there has been a growing demand for high skilled labor that is not being met, leading to rising wages for jobs that require those skills. Our objective is to research which high skill position jobs in the City of Boise are seeing higher than average annual wage growth. This information will give us more insight as to why, despite the rising wages, not enough high skilled labor is being supplied in order to meet the demand for certain jobs. We hope the City of Boise will be able to use our research to attract high skilled workers in local industries where they are lacking. Through the direction of a Boise Job Recruiter we will focus our research on several specific skilled position jobs that are seeing higher wage increases than average. Basic information will be gathered through various websites such as clustermapping.us, bls.gov, and others. More detailed information will be obtained via email, phone calls, and in-person meetings with various companies who are seeing this lack of skilled work being filled. We will be contacting several large companies in the City of Boise that employ skilled workers in order to learn more about their current wages compared to typical wage growth. We are also expecting to learn which skilled jobs in Boise are seeing higher wage increases and the economic reasoning behind these increases compared to typical wage growth
Treatment of Persistent Air Leaks using Endobronchial Valves
Introduction: Persistent air leaks (PAL) are from bronchopleural fistula resulting from communication between the bronchial tree and pleural space. Endobronchial valves (EBVs) are unidirectional valves placed bronchoscopically preventing airflow to the diseased lung lobe. For non-operable patients with PALs, EBVs offer a potential non-invasive treatment approach to stop air leak and allow lung healing. The purpose of this study is to retrospectively analyze EBV placement to treat non-operable adult patients with PALs.
Methods: We retrospectively analyzed all adult patients that underwent EBV placement for PAL treatment at our institution from January 2016 to June 2019. All patients failed conservative therapy with chest tubes before EBV placement. Descriptive statistics were used to analyze leak etiology, number of valves placed, duration of placement, and PAL resolution.
Results: A total of 20 EBV procedures occurred in patients with a median age of 63 (range = 38–79). Air leaks were spontaneous in 13 patients and either due to post-surgical or iatrogenic causes in 7 patients. By last follow-up, 60% of patients still retained all valves. Among patients that had valves removed, EBVs were in place for a median of 6 months (range = 2–21). 19 patients PALs resolved after EBV placement.
Discussion: Our data supports previous reports of the feasibility of successfully treating PALs using EBVs. Although this report requires validation in a larger cohort, our data suggests that compassionate exemption EBV placement can be a possible treatment alternative to current standard of care for patients with PALs that are non-operable
Unveiling Candida albicans intestinal carriage in healthy volunteers: the role of micro- and mycobiota, diet, host genetics and immune response
Candida albicans; Colonization resistance; MetagenomicsCandida albicans; Resistència a la colonització; MetagenòmicaCandida albicans; Resistencia a la colonización; MetagenómicaCandida albicans is a commensal yeast present in the gut of most healthy individuals but with highly variable concentrations. However, little is known about the host factors that influence colonization densities. We investigated how microbiota, host lifestyle factors, and genetics could shape C. albicans intestinal carriage in 695 healthy individuals from the Milieu Intérieur cohort. C. albicans intestinal carriage was detected in 82.9% of the subjects using quantitative PCR. Using linear mixed models and multiway-ANOVA, we explored C. albicans intestinal levels with regard to gut microbiota composition and lifestyle factors including diet. By analyzing shotgun metagenomics data and C. albicans qPCR data, we showed that Intestinimonas butyriciproducens was the only gut microbiota species whose relative abundance was negatively correlated with C. albicans concentration. Diet is also linked to C. albicans growth, with eating between meals and a low-sodium diet being associated with higher C. albicans levels. Furthermore, by Genome-Wide Association Study, we identified 26 single nucleotide polymorphisms suggestively associated with C. albicans colonization. In addition, we found that the intestinal levels of C. albicans might influence the host immune response, specifically in response to fungal challenge. We analyzed the transcriptional levels of 546 immune genes and the concentration of 13 cytokines after whole blood stimulation with C. albicans cells and showed positive associations between the extent of C. albicans intestinal levels and NLRP3 expression, as well as secreted IL-2 and CXCL5 concentrations. Taken together, these findings open the way for potential new interventional strategies to curb C. albicans intestinal overgrowth.This work was supported by a grant from Agence Nationale de la Recherche (FunComPath ANR-14-IFEC-0004), the French Government’s Investissement d’Avenir program (Laboratoire d’Excellence Integrative Biology of Emerging Infectious Diseases [ANR10-LABX-62-IBEID], and [ANR-10-LABX-69-01]), the European Union’s Horizon 2020 research and innovation program under the Marie Sklodowska-Curie action, Innovative Training Network (FunHoMic; Grant No. 812969), and the European Union’s Horizon 2020 Research and Innovation Program (HDM-FUN, Grant No. 847507).
