Cultures of listening, dark listening and a plea for theory
Authors: Motzkau Johanna 
Published: July 2021

AbstractRussi (2021) suggests ‘eavesdropping’ as a way to appreciate the practical implications of Shotter’s (2015) stance that social inquiry is an art/craft beginning with experience, rather than a technique pre‐determined by theory and methods. Following Russi’s instruction to eavesdrop on his eavesdropping, I explore his concepts of experience and listening. Contrary to Russi I issue a plea for theory, as theoretical frameworks are key for tracking the politics of knowledge surrounding social inquiry. Illustrating the process theoretical character of Russi’s concepts of experience and listening, I argue for the possibility of theory as emergent within experience. Here my concept of cultures of listening is relevant, as it helps to consider eavesdropping as a form of dark listening (Motzkau & Lee, forthcoming).

Published: July 2021

AbstractBackgroundIrreversible sensorineural auditory loss has been reported in humans treated with aminoglycosides but not in horses.ObjectiveInvestigate if auditory loss occurs in horses treated using the recommended IV daily dosage of gentamicin for 7 consecutive days.AnimalsTen healthy adult horses (7‐15 years; females and males, 5 each).MethodsProspective study. Physical and neurological examinations and renal function tests were performed. Gentamicin sulfate was administered at a dosage of 6.6 mg/kg via the jugular vein on alternating sides for 7 days. Gentamicin peak and trough concentrations were measured. Horses were sedated using detomidine hydrochloride IV to perform brainstem auditory evoked responses (BAER) before the first dose, immediately after the last dose, and 30 days after the last dose. Peaks latencies, amplitudes, and amplitude ratios were recorded. Data from the second and last BAER were compared to results at baseline. Bone conduction was performed to rule out conduction disorders.ResultsSeven horses had auditory loss: complete bilateral (N = 1), complete unilateral (N = 2), and partial unilateral (N = 4). Based on physical examination and BAER results, sensorineural auditory loss was suspected. Absent bone conduction ruled out a conduction disorder and further supported sensorineural auditory loss in horses with completely absent BAER. Auditory dysfunction was reversible in 4 of 7 horses.Conclusions and Clinical ImportanceGentamicin at recommended doses may cause sensorineural auditory loss in horses that might be irreversible. Follow‐up studies are needed to investigate if other dosing protocols present a similar risk.

AbstractBackgroundPolymorphisms of the vitamin D receptor (VDR) are associated with calcium oxalate (CaOx) nephrolithiasis in humans.ObjectivesTo investigate the association betweenVDRpolymorphisms and susceptibility to CaOx urolithiasis in dogs.AnimalsThirty‐five dogs with CaOx urolithiasis were compared with 40 stone‐free dogs.MethodsThis was a case‐control study. TwoVDRgene polymorphisms (rs851998024 and rs852900542) were detected by specific TaqMan real‐time polymerase chain reaction assay, and their relationship with serum 1,25‐dihydroxyvitamin D, serum and urinary electrolyte concentrations was evaluated.ResultsThe distribution of the rs852900542 polymorphism was significantly different between the case and the control dogs (x2 = 6.369,P = .04). Dogs with a CC or CT genotype had an increased risk of CaOx stones than those with the TT genotype (odds ratio = 3.82, 95% confidence interval 1.04‐13.98). The CaOx dogs with the TT genotype had a significantly lower urinary calcium‐to‐creatinine ratio than the CT+CC genotypes. 1,25‐(OH)2D concentrations did not differ between the cases and the controls (308.7 ± 217.4 vs 286.7 ± 185.1 pg/mL,P = .45).Conclusions and Clinical ImportanceThis finding suggests that vitamin D metabolism might play a role in CaOx stone formation in dogs.
Yilan crater, China: Evidence for an origin by meteorite impact

Published: July 2021

AbstractThe Yilan crater is 1.85 km in diameter and is located in the northeast of China's Heilongjiang Province. The crater is exposed in the Early Jurassic granite of the regional Paleozoic–Mesozoic granite complexes. The southern third of the crater rim is missing, but other rim sections are well preserved, with a maximum elevation above the present crater floor of 150 m. A drillcore from the center of the structure shows that the crater fill consists of 110 m thick lacustrine sediments underlain by a 319 m thick brecciated granite unit mainly composed of unconsolidated granite clasts and fragments. Melt products derived from the target granite, which include melted (and recrystallized) granite clasts, vesicular glass, and teardrop‐shaped glass, were found in the brecciated granite unit at 218–237 m depth. Petrographic investigations of unmelted granite clasts in the brecciated granite unit from this depth interval show the presence of multiple sets of planar deformation features (PDFs) in quartz. Orientation measurements for 79 PDF sets in 38 quartz grains with a U‐stage indicate the dominance of the ω{103} and π{102} orientations with a relative frequency of 39% and 18%, respectively. Only 7.6% of the observed PDFs remain unindexed. The observations of PDFs with the appropriate orientations are clear evidence of shock metamorphism and thus of an impact origin of the Yilan structure. Crystallite aggregates of coesite embedded in silica glass were found in the impact‐melted granite clasts. The carbon‐14 dates of possibly impact‐produced charcoal and lacustrine sediments from the crater fill suggest a young age for the impact event of 0.0493 ± 0.0032 Ma.

AbstractBackgroundIn March 2018, three patients were admitted to the Emergency Department of a District General Hospital. Originally suspected of having suffered an opiate overdose, it became clear that they were the victims of anti‐cholinesterase poisoning—the Soviet era poison Novichok. Twenty‐five days later, two further patients were admitted with the same symptoms. One of these patients died 8 days later and the second remained in hospital for 3 weeks. A Clinical Psychologist was present on the unit throughout the major incident and all staff directly involved received psycho‐educational support regarding self‐care.AimsTo examine the psychological impact of the longest running major incident in NHS history on the staff directly involved.DesignA cross‐sectional design was used, with structured questionnaires administered retrospectively.MethodsA link to an electronic survey was emailed to every member of staff in the organization. The survey included the Hospital Anxiety and Depression Scale, the Maslach Burnout Inventory, the Impact of Events Scale—Revised (to both the March and June events).Results540/4000 hospital staff responded (13.5% response rate) with a 29/59 (49%) response rate in intensive care staff. Frontline staff had significantly lower scores on anxiety (P < .05 for the June incident), depressive symptoms (P < .05 March and June) and subscales of burnout than managers (depersonalization P < .05). On the remaining two burnout subscales and on anxiety scores for those involved in March, results trended towards significance (P < .1).ConclusionsStaff in management roles during major incidents may experience higher levels of psychological distress than staff in front line clinical roles and should be encouraged to seek psychological support.Relevance to Clinical PracticeThis article informs teams of the psychological impact of major incidents on staff in intensive care settings.
Reflections on researching vulnerable populations: Lessons from a study with Bhutanese refugee women
Authors: Parajuli Jamuna , Horey Dell 
Published: July 2021

AbstractThis paper explores the critical roles of researchers in research involving vulnerable populations. Its purpose is to reflect on the complex nature of vulnerability of Bhutanese refugee women who had resettled in Australia involved in research looking at the barriers to accessing preventive cancer screening. First, we describe the vulnerabilities considered prior to the research study and the actions taken to protect participants while the study was conducted. Second, we discuss those vulnerabilities that we did not anticipate, but were subsequently revealed during the study and consequently included in the study findings. These vulnerabilities should be considered for future research involving similar populations. It is important for researchers to use appropriate research designs that enable the voice of vulnerable people to be heard and to use research strategies that ensure findings are robust and participants are protected and empowered. Potential implications include the development of research practices that take account of the sources of vulnerabilities and consideration of how different vulnerabilities can evolve and affect findings and research recommendations.
Explaining normative reasons
Authors: Fogal Daniel , Risberg Olle 
Published: July 2021

AbstractIn this paper, we present and defend a natural yet novel analysis of normative reasons. According to what we callsupport‐explanationism, for a fact to be a normative reason toφis for it to explain why there's normative support forφ‐ing. We critically consider the two main rival forms of explanationism—ought‐explanationism, on which reasons explain facts about ought, andgood‐explanationism, on which reasons explain facts about goodness—as well as the popular Reasons‐First view, which takes the notion of a normative reason to be normatively fundamental. Support‐explanationism, we argue, enjoys many of the virtues of these views while avoiding their drawbacks. We conclude by exploring several further important implications: among other things, we argue that the influential metaphor of ‘weighing’ reasons is inapt, and propose a better one; that, contrary to what Berker (2019) suggests, there's no reason for non‐naturalists about normativity to accept the Reasons‐First view; and that, contrary to what Wodak (2020b) suggests, explanationist views can successfully accommodate what he calls ‘redundant reasons’.

Published: July 2021

AbstractInternationally, Eurocentric hegemonies rooted in coloniality dominate the discourse on environmental wellbeing and sustainable development. Māori frameworks are being used and developed in Aotearoa New Zealand to support bicultural approaches to the management of natural resources and built environments. This paper reports on an Atua (Māori gods and spirits) framework that was found to be valuable as a cultural lens for the co‐creation of a toolkit for assessing the wellbeing of indigenous forests. This article provides guidance on the development and application of kaupapa Māori frameworks, particularly Atua frameworks, in wider geographical contexts including urban design and spatial planning.

Published: July 2021

AbstractObjectivesDentofacial orthopaedic treatment of mandibular hypoplasia has unpredictable skeletal outcomes. Although several biomodulators including insulin‐like growth factor 1 (IGF‐1) are known to contribute to chondrocyte proliferation, their efficacy in modulating mandibular growth has not been validated. The aim of this study was to determine the effect of locally delivered IGF‐1 on mandibular growth and condylar bone quality/quantity in juvenile rats.Setting and sample populationInstitutional vivarium using twenty‐four 35‐day‐old male Sprague‐Dawley rats.MethodsPBS or 40 µg/kg (low‐dose) IGF‐1 or 80 µg/kg (high‐dose) IGF‐1 was injected bilaterally into the temporomandibular joints of the rats at weekly intervals for four weeks. Cephalometric and micro‐computed tomography measurements were used to determine mandibular dimensions. Bone and tissue mineral density, volume fraction and mineral content were determined, and serum IGF‐1 concentrations assayed.ResultsIntra‐articular administration of high‐dose IGF‐1 contributed to a significant 6%‐12% increase in mandibular body and condylar length compared to control and low‐dose IGF‐1‐treated animals. Additionally, IGF‐1 treatment resulted in a significant decrease in the angulation of the lower incisors to mandibular plane. Condylar bone volume, bone volume fraction, mineral content and mineral density were significantly increased with high‐dose IGF‐1 relative to control and low‐dose IGF‐1 groups. Serum IGF‐1 levels were similar between all groups confirming limited systemic exposure to the locally administered IGF‐1.ConclusionLocal administration of high‐dose 80 µg/kg IGF‐1 enhances mandibular growth and condylar bone quality and quantity in growing rats. The findings have implications for modulating mandibular growth and potentially enhancing condylar bone health and integrity.

Published: July 2021

AbstractIntroductionMicrosporidiosis is an emerging opportunistic infection in renal transplantation (RT) recipients. We aimed to describe its clinical presentation and treatment.Materials and methodsWe collected microsporidiosis cases identified in RT recipients between 2005 and 2019 in six French centers from the Crystal, Divat and Astre prospective databases.ResultsWe report 68 RT recipients with intestinal microsporidiosis; the patients were predominantly male (61.8%), with a median age of 58 (46–69) years. Infection occurred at a median time of 3 (0.8–6.8) years posttransplant. Only Enterocytozoon bieneusi was found. Microsporidiosis manifested as diarrhea (98.5% of patients) with weight loss (72.1%) and acute renal injury (57.4%) without inflammatory biological parameters. The therapeutic approaches were no treatment (N = 9), reduction of the immunosuppressive regimen (∆IS) (N = 22), fumagillin alone (N = 9), fumagillin and ∆IS (N = 19), and albendazole or nitazoxanide and ∆IS (N = 9). Overall clinical remission was observed in 60 patients (88.2%). We observed no acute kidney rejection, renal transplant failure, or death within 6 months after microsporidiosis.ConclusionE. bieneusi is an underestimated opportunistic pathogen in RT recipients, and infection with E. bieneusi leads to diarrhea with important dehydration and acute renal injury. The treatment is based on the reduction of the immunosuppressive regimen and the administration of fumagillin if available.

Published: July 2021

Abstract
An innovative methodology and a virtual test bench (VTB) are proposed to support the design of water heaters’ control strategies. This platform allows to speed up the development and evaluation of control systems even before the existence of prototypes or real test environments. By simulating the environmental conditions and the state of the different device components, it will be possible to detect and correct possible initial errors in the control system design which can be time consuming and costly due to subsequent modifications to the system or equipment components. The architecture of the proposed system establishes four operating modes: open-loop data acquisition, real-time simulation, hardware-in-the-loop simulation, and test of the complete real system, the incorporation of these functionalities in the same platform is not reported in the literature for domestic water heaters. The virtual test bench was designed to accommodate different water heaters including, but not limited to, gas, electric, and heat pumps, for instantaneous hot water production or including hot water storage. The prototype of the virtual test bench is described emphasizing the hardware-in-the-loop methodologies and embedded control. The particular case study of a tankless gas water heater (TGWH) is presented implementing the different operation modes in the virtual test bench. The water heater models, control strategies, simulation, and experimental data are presented and discussed.
Role of Inlet Boundary Conditions on Fuel-Air Mixing at Supercritical Conditions
Authors: Harris Zachary , Bittle Joshua , Agrawal Ajay 
Published: July 2021

Abstract
Advanced engine design and alternative fuels present the possibility of fuel injection at purely supercritical conditions in diesel engines and gas turbines. The complex interactions that govern this phenomenon still need significant research, particularly the boundary conditions for fuel injection are critical for accurate simulation. However, the flow inside the injector itself is often omitted to reduce the computational efforts, and thus, velocity, mass flux, or total pressure is specified at the injector exit (or domain inlet), often with simplified velocity profiles and turbulence levels. This simplified inlet boundary treatment has minimal effects on results for conventional fuel injection conditions, however, the validity of this approach at supercritical conditions has not been assessed. Comprehensive real-gas and binary fluid mixing models have been implemented for computational fluid dynamics (CFD) analysis of fuel-air mixing at supercritical conditions. The model is verified using prior CFD results from the literature. The model is used to investigate the effects of the shape of axial velocity and mass fraction profiles at the inlet boundary with the goal to improve the comparison of predictions to experimental data. Results show that the boundary conditions have a significant effect on the predictions, and none of the cases match precisely with experimental data. The study reveals that the physical location of the inlet boundary might be difficult to infer correctly from the experiments and highlights the need for high-quality, repeatable measurements at supercritical conditions to support the development of relevant high-fidelity models for fuel-air mixing.
Numerical and Experimental Study on the Impact of Mild Cold Exhaust Gas Recirculation on Exhaust Emissions in a Biodiesel-Fueled Diesel Engine
Authors: de Oliveira Alex , Yang Junfeng , Sodré José Ricardo 
Published: July 2021

Abstract
This work evaluated the effect of cooled exhaust gas recirculation (EGR) on fuel consumption and pollutant emissions from a diesel engine fueled with B8 (a blend of biodiesel and no. diesel 8:92% by volume), experimentally and numerically. Experiments were carried out on a diesel power generator with varying loads from 5 kW to 35 kW and 10% of cold EGR ratio. Exhaust emissions (e.g., total hydrocarbons (THCs), nitrogen oxides (NOx), carbon monoxide (CO), etc.) were measured and evaluated. The results showed mild EGR and low biodiesel content have minor impact of engine-specific fuel consumption, fuel conversion efficiency, and in-cylinder pressure. Meanwhile, the combination of EGR and biodiesel reduced THC and NOx up to 52% and 59%, which shows promising effect on overcoming the particulate matter–NOx tradeoff from diesel engine. A three-dimensional computational fluid dynamics engine model incorporated with detailed biodiesel combustion kinetics and NOx formation kinetics was validated against measured in-cylinder pressure, temperature, and engine-out nitric oxide emission from diesel engine. This valid model was then employed to investigate the in-cylinder temperature and equivalence ratio distribution that predominate NOx formation. The critical results showed that the reduction of NOx emission by EGR and biodiesel is obtained by a little reduction of the local in-cylinder temperature and, mainly, by creating comparatively rich combusting mixture, which makes the combustion path pass through lower NOx zone in the ϕ–T diagram.
Performance of a Long Smooth Multiphase Pump Seal in Different Flow Regimes
Authors: Zhang Min , Childs Dara W. 
Published: July 2021

Abstract
Demanding for multiphase pumps introduces new challenges to the pump design. To prevent machine failures, the performance of the pump (noncontact) annular seal under multiphase conditions needs to be studied. The air addition into the oil flow not only changes the properties of the fluid but also can change the flow status in the seal clearance. The flow status can significantly affect the performance of the pump seal and thereby impact the pump vibration performance. Within the seal annulus, the axial direction flow is dominated by the pressure drop through the seal and can be considered as a Poiseuille flow. The circumferential direction flow is driven by the rotor rotation and can be considered as a Couette flow. The regime of the flow in the seal is controlled by the axial Reynolds number and the circumferential Reynolds number. Published test results on the boundaries between the laminar, transitional, and turbulent regimes in an annular seal are scant. This article will first draw these boundaries based on the test data for long smooth pump seals. Then, this article will show the performance of the long smooth pump seal in different flow regimes. Predictions will also be presented to compare with test results under different flow conditions.
Noise Characteristics of Automobile Cooling Fan Based on Circumferential Mode Analysis

Published: July 2021

Abstract
The fan is the main component of the cooling system of an automobile engine. A typical automobile cooling fan consists of a shrouded axial fan, stator vanes, a deflector, and a cover. With recent developments in the automobile industry, the increase in the speed of rotation and blade load of cooling fans has increased the noise generated by them. To reduce it, it is important to analyze the characteristics of this noise. This paper uses an acoustic test to examine the characteristics of flow and noise of automobile cooling fans. The frequency spectrum and far-field radiation of the noise of the fan are first analyzed through far-field measurements, and the influence of the single rotor, tip clearance of the blade, and cover on fan noise is studied. The distribution of the mode spectrum and characteristics of sound propagation of discrete tonal noise are then examined using the circumferential mode test. The influence of the flow structure on fan noise is also studied. The flow characteristics and distribution of the source of noise of the automobile cooling fan are then used to analyze the influence of the structure of the fan on the noise generated by it. The results can help develop designs to reduce the noise of automobile cooling fans.
