Hybrid Artificial Boundary Conditions for the Application of Blunt-Body Aerodynamic Noise Prediction

A hybrid artificial boundary condition (HABC) that combines the volume-based acoustic damping layer (ADL) and the local face-based characteristic boundary condition (CBC) is presented to enhance the absorption of acoustic waves near the computational boundaries. This method is applied to the prediction of aerodynamic noise from a circular cylinder immersed in uniform compressible viscous flow. Different ADLs are designed to assess their effectiveness whereby the effect of the mesh-stretch direction on wave absorption in the ADL is analysed. Large eddy simulation (LES) and FW-H acoustic analogy method are implemented to predict the far-field noise, and the sensitivities of each approach to the HABC are compared. In the LES computed propagation field of the fluctuation pressure and the frequency-domain results, the spurious reflections at edges are found to be significantly eliminated by the HABC through the effective dissipation of incident waves along the wave-front direction in the ADL. Thereby, the LES results are found to be in a good agreement with the acoustic pressure predicted using FW-H method, which is observed to be just affected slightly by reflected waves.
Fully developed and transient concentration profiles of particulate suspensions sheared in a cylindrical Couette cell

We experimentally investigate particle migration in a non-Brownian suspension sheared in a Taylor–Couette configuration and in the limit of vanishing Reynolds number. Highly resolved index-matching techniques are used to measure the local particulate volume fraction. In this wide-gap Taylor–Couette configuration, we find that for a large range of bulk volume fraction, $\unicode[STIX]{x1D719}_{b}\in [20\,\%{-}50\,\%]$ , the fully developed concentration profiles are well predicted by the suspension balance model of Nott & Brady (J. Fluid Mech., vol. 275, 1994, pp. 157–199). Moreover, we provide systematic measurements of the migration strain scale and of the migration amplitude which highlight the limits of the suspension balance model predictions.
Caracterisation hydrogeologique d'un aquifere en socle fracture : site de ploemeur (morbihan)

En Bretagne, l'alimentation en eau potable est assuree a 20% par les ressources en eaux souterraines contenues, principalement dans le socle fracture. Du fait de la geometrie du reseau de fractures et des proprietes hydrauliques des roches, la productivite des aquiferes bretons est generalement faible (400 a 1000 m3/j). A Ploemeur(Morbihan), un important gisement d'eau souterraine est exploite pour l'alimentation en eau potable, depuis juin 1991, a un debit moyen de 3000 m3/j. Les caracteristiques principales de cet aquifere sont 1) des arrivees d'eaux importantes, localisees au niveau de filons de pegmatites fracturees, et 2) une eau brute de bonne qualite ([N03]<1 Omg/I). Dans les milieux fractures, les circulations de fluide et le transport de matiere sont fortement dependantes de la geometrie du reseau de fracture. C'est pourquoi, une meilleure comprehension du fonctionnement hydrogeologique est fondamentale quant a la gestion et la protection des ressources en eaux souterraines. Nous avons entrepris une caracterisation hydrogeologique afin de definir la structure du sous-sol e~ d'identifier les principaux processus a l'origine de la productivite de cet aquifere et de la qualite de l'eau. Cette etude pluridisciplinaire est basee sur des observations de terrain et sur l'utilisation de methodes geophysiques, hydrauliques et hydrochimiques. La zone fracturee se trouve au contact entre des micaschistes et du granite et possede une geometrie subhorizontale favorisant sa recharge donc sa productivite. Ce modele contraste avec ce qui est traditionnellement propose pour les milieux fractures en Bretagne. L'imagerie geophysique donne grossierement la geometrie mais ne permet pas une detection fine des filons de pegmatites fractures. Des essais de pompage ont permis de caracteriser les proprietes hydrauliques. Ce type d'aquifere ne repond pas aux modeles standards developpes en hydrogeologie; a la 1 fois, par son heterogeneite intrinseque et par la dimension de la zone d'ecoulement. Par consequent, le modele mOy9n qui semble approprie est un aquifere fractal de dimension 1,4. Enfin l'analyse des chroniques chimiques, notamment des nitrates, a mis en evidence les processus 1) de melange d'une eau recente (infiltree apres 1950 et polluee par les nitrates) avec une eau ancienne et 2) de denitrification naturelle par oxydation de la pyrite. Une modelisation de ces chroniques sur la base d'une denitrification bacterienne a permis de quantifier la cinetique de cette reaction d'oxydo-reduction et la dynamique du melange qui evolue pendant le - ~ - pompage, par la mise en ecoulement de drains preferentiels, entre la surface et la zone fracturee profonde.
Glycemic Control and Metabolic Parameters in Children and Adolescents With Type 1 Diabetes

Aim: The association between glycemic control and metabolic status is poorly defined in children and adolescents with T1D, besides being biologically plausible. We aimed to evaluate the association between glycemic control and body mass index (BMI), blood pressure (BP), and lipid profile in children and adolescents with T1D. Methods: Observational cross-sectional study including children and adolescents (5-18 years old) followed in our outpatient clinic with the diagnosis of T1D for at least a year. We used linear regression models (unadjusted and adjusted to sex and age) to evaluate the association between glycated hemoglobin (A1c) and time in range (TIR), several prespecified metabolic parameters, and prespecified demographic and clinical characteristics. We considered a p-value of <0.05 to be statistically significant. Results: A total of 144 patients were included, 51% of whom were female. The population had a mean age of 12.7±3.4 years old. We report a positive association between A1c and BMI, systolic and diastolic BP, total- and LDL-cholesterol and triglycerides. Females and patients diagnosed at a younger age presented with higher A1c values. There is a tendency for a negative association between TIR and the former parameters. Higher A1c levels and lower TIR were associated with higher glycemic variability and were treated with a higher basal insulin per Kg dose. Conclusion: Our results support an important association between worse glycemic control and an unhealthier metabolic profile in children and adolescents with T1D. We can hypothesize that a good glycemic profile is needed to achieve good metabolic control at a young age.
ANALYSIS OF ADVERSE DRUG REACTIONS TO ANTIRETROVIRALS USE IN A SECONDARY HOSPITAL

Although antiretrovirals (ARV) evidently extend the life expectancy of people living with HIV/AIDS (PLWH), their associated Adverse Drug Reactions (ADRs) are unavoidable, particularly in long-duration regimens. Several studies have reported a correlation between ADRs and adherence to ARV therapy. Meanwhile, ARV is the main determinant of achieving an immunological and virologic response. Pharmacists play the role of counselors in improving therapeutic outcomes including ADR management. This study aimed to analyze ADRs induced by ARV based on pharmacy documentation and to describe the frequency of PLWH follow-up visits over a two-year period. The study was conducted at Sleman Regional Hospital, an HIV/AIDS referral hospital in Yogyakarta. A cross-sectional design was used with saturated sampling, including all ARV use for HIV/AIDS. Data were collected from the pharmacy unit and patients’ spontaneous reports. Prescribed ARV came from the electronic system, whereas ADR reports were from patients during voluntary consultation with the pharmacist or in PITC services. A total of 110 ARV were administered mostly to male patients aged 25-40 years. The most regimen was tenofovir+lamivudine+efavirenz (91%) with the highest frequency of follow-up visits ? 12 times (53%). The top three ADRs were dizziness (30%), nausea (11%), and headache (8%). Three of the four pediatric patients experienced ADRs, each with AZT-induced fatigue, bloating, and diarrhea in LPV/r monotherapy. Most of the patients did not maintain appointments for hospital visits. Further studies are recommended to analyze the causative factors of non-adherence, including the loss to follow-up group.

Analysis of the Explanatory Factors of Hypertension in People Aged 30 to 64 in Benin

In Benin, hypertension is a leading cause of death and a significant contributor to the disease burden. This study aims to determine the explanatory factors of high blood pressure among people aged 30 to 64 years in Benin. We used data from Benin's 2017-2018 Demographic Health Survey to analyse hypertension determinants. Based on the Akaike Information Criterion (AIC) score, the Probit model (5922.56) is a better fit for the data than the Logit model (5924.997). The probit estimate indicates that the likelihood of having high blood pressure increases, with odds ratios ranging from 1.1453 for the age group of 35-39 years to 1.9572 for the age group of 50-54. Being female, living in the South or Centre region, having higher education levels, and having diabetes also increase the likelihood of having high blood pressure. These findings provide insight into the factors that contribute to the prevalence of high blood pressure and may help inform public health interventions aimed at reducing its incidence.
FAMILY OWNERSHIP MATTERS FOR INVESTORS IN INDONESIA'S MINING COMPANIES

This study aims to determine the effect of family ownership, financial performance, return on assets, return on equity, liquidity, and capital structure on market value. Secondary data was obtained based on annual reports and financial statements in mining companies listed on the IDX in 2016-2020 through Indonesia Stock Exchange (IDX). Data were obtained from the Bloomberg database. The method used to collect samples is purposive and consists of 35 mining companies in Indonesia. The panel data method was considered appropriate in this study, and multiple regression was used to examine the data. The results show that total assets and return on assets positively affect market value. The ratio of return on equity and liquidity in financial performance and capital structure has no significant effect on market value. The existence of family ownership is favourable for a firm’s market value. The sample in this study was limited to the manufacturing sector. This industry was chosen because its market value is quite volatile and family ownership is quite large. On average there are 40% of the total observations are family-owned companies. The interesting findings in this study are that family ownership does matter in gaining the investors’ attention.
Clinico-Demographic Profile and Factors Affecting Duration of Hospital Stay Among Burn Patients in an Emergency Department of a Tertiary Care Center, South India: A Hospital-Based Cross-Sectional Study

Background Burns continue to be a serious public health problem in India. It persists as an endemic disease in spite of implementing various preventive measures at the individual and community levels. Etiology and factors influencing burns are varied. There is a paucity of data regarding the clinico-demographic profile of burns disease, especially from emergency tertiary care settings in India. Objective To assess the proportion of burn patients having longer hospital stays (>1 week) and the influence of clinico-demographic factors associated with it among the burn patients presenting to the emergency department of a tertiary care institute in south India. Methodology An institution-based cross-sectional analytical study was conducted among burns patients attending the Emergency Medicine Department (EMD) of a tertiary care center between January 2017 and December 2017. Information on clinico-demographic profile and duration of hospital stay were captured using semi-structured data collection proforma. Results All the 327 burns injury patients who presented to our EMD during the study period were included. Among the 327 patients, 259 (79%) were admitted to the EMD. Among 259 admitted patients, 142 (55%) patients were discharged home. Among these 142 patients, 106 (74.6%; 95%CI 66.8-81.2) had longer hospital stays (more than one week). Female gender and facial/inhalational burns were found to have an independent effect on the length of hospital stay even after adjusted analysis. Conclusion Length of hospital stay is independently influenced by female gender and facial/inhalational burns. This study also identified the need for better home safety, child-proofing, proper pre-hospital care, and dedicated burns units in the community.
Evaluation of runoff response to moving rainstorms

EVALUATION OF RUNOFF RESPONSE TO MOVING RAINSTORMS JIN LIANG Marquette University, 2010 The primary hypothesis from the hydrological literature is that downstream moving storms with storm length ( ) less than watershed length ( ) magnify the peak discharges. This hypothesis was developed from the kinematic-wave modeling, and was evaluated in a plot between the dimensionless peak discharge and dimensionless storm velocity. Previously unpublished experimental data collected from the Watershed Experimentation System (WES), obtained from the late Professor Ben C. Yen at the University of Illinois at Urbana-Champaign, were used in comparison with the simulation results of the kinematic-wave model. It is found that downstream moving storms with ⁄ 1 increase the peak discharges to a limited extent compared to stationary storms, but the kinematic-wave model overstates the increase in the peak flows resulting from downstream moving storms with ⁄ 1. This difference between model projections and laboratory data was attributed to backwater effects in the experimental runoff. To evaluate the importance of the backwater effects, the accuracy of kinematic-wave and dynamic-wave models for the simulation of surface runoff resulting from moving storms was evaluated utilizing the same experimental data. It is found that, the kinematic-wave model cannot deal with the backwater effects resulting from downstream moving storms in the V-shaped watershed in the WES. The kinematic-wave model simulates the upstream moving storms pretty well, whereas it totally overestimates the peak discharges for downstream moving storms. To confirm the reliability of the nondimensional plots it was necessary to evaluate the kinematic-wave based equations for estimation of the time of concentration. Three methods, i.e., Ben-Zvi’s method, the modified Ben-Zvi method, and Izzard’s method were applied to determine the time of concentration from the experimental hydrographs of stationary rainstorms reaching the equilibrium state from the WES. The times of concentration determined by these three methods were compared to the mathematical equation proposed by Wong. It is found that a percentage of 89% can be a generally agreeable percentage to evaluate the experimental data from the WES. It is concluded that Wong’s equation can predict the time of concentration acceptably well for the simplified watershed with mild overland and channel slopes and long durations.

On the Relationship of Iranian EFL Learners’ Engagement and Self-regulation with Their Learning Outcomes

Background. Language learning is a long and tedious process and some students may lose their initial interest, so their learning achievement might in turn decrease. Student engagement and self-regulation can be seen as influential in helping them to restore their enthusiasm and motivation. Engagement can assist students to be actively involved in their school work in order to become more motivated and interested in language learning. Further, self-regulation also seems to contribute to have students regulate their learning behavior and engagement, which could possibly play a role in their learning outcomes. Purpose. The purpose of this study was thus to investigate the relationships of self-regulation and student engagement with learning outcomes. Method. The participants, selected through convenience sampling, included 146 language learners learning English at the Iran Language Institute (ILI) Gorgan, Iran. They were given two questionnaires and a language proficiency test. Results. The obtained data were analyzed by using SPSS, version 26. The results of Spearman’s rho correlation tests indicated that there were statistically significant relationships of self-regulation and student engagement with learning outcomes, with student engagement having a stronger association with learning outcomes. Moreover, student engagement as a global construct was a better predictor of learning outcomes. Conclusion. Since student engagement is comparatively new in the realm of language education, the findings can contribute to our understanding of its role in learning outcomes. Besides, the results have pedagogical implications for language learners and language teachers alike.
High-diffraction-efficiency Fresnel lens based on annealed blue-phase liquid crystal–polymer composite

ABSTRACT We demonstrated a relatively simple and effective method to fabricate a periodically isolated polymer wall of blue-phase liquid crystal Fresnel lens (BPLCFL) by employing a single-masking process of the ultraviolet (UV) irradiation, leading to excellent photopolymerisation-induced phase separation between blue -phase liquid crystal (BPLC) molecules and UV-curable monomers. Nevertheless, some uncured monomers would inherently reside in the BPLC-rich area and slightly inhibit the BPLC molecules realigned under the external electric field. To enhance the optical properties of the polymer-wall BPLCFL considerably, a novel technique for fabricating a pure BPLC zone is proposed that successfully expels the residual monomers from the BPLC volume using a thermal annealing process. Experimental results show that the maximum diffraction efficiency reaches ~36%, which approaches the theoretical limit of ~41%. Consequently, the annealing technique to purify phase-separated composite films has a strong potential to construct the BPLCFL in light of polarisation-free applications. Graphical Abstract
Socio-Economic Factors Influencing Woodlot Farming Adoption from Crop Farming in Tanzania: A Case of Mufindi District

The study stressed to examine socio – economic factors influencing woodlot farming adoption in Mufindi district, Tanzania. The study used questionnaire to collect data from 40 woodlot owners (sample size). The collected data were analyzed using multinomial logistic model. Findings show that the high income generating expectation, land size, and assets acquisitions both influence woodlot farming adoption positively and significantly while education level influence woodlot farming adoption negatively and significantly. Basing on the findings, the study concluded that socio-economic factors that influence woodlot farming positively and significantly are income generation expectation, land size, and assets acquisitions meanwhile education level influence woodlot farming adoption negatively and significantly. Based on the findings, this study recommends that there is a need for government to support the woodlot owners by providing subsidies including inputs such as land, fertilizers, and quality seeds through Mufindi district officials so as to create employment opportunities among majority of rural households and raise their standard of living. If all these recommendations are implemented, then improvement in the income from woodlot farming would ultimately be realized.
