The Ecological-Health Risks of Potentially Toxic Metals in the Surface Sediments and Leaves of Salt-Secreting Avicennia officinalis as Potential Phytoremediators: A Field-Based Biomonitoring Study from Klang Mangrove Area

Simple Summary This study evaluated the capacity for the phytoremediation of mangrove Avicennia, sampled from the Klang mangrove ecosystem, and analysed the ecological-health concerns of potentially toxic metals in the surface sediments. All of the hazard index values of the surface sediments for Cu, Ni, Pb, and Zn, based on a combination of three pathways, indicated 1.00, suggesting that the four metals are not carcinogenic. The lamina has more potential as a phytoremediator of vital Cu, Zn, and Fe, according to the bio-concentration factor values. As a phytoremediator of non-essential Pb and Ni, midrib plus petiole has greater potential. The data presented in this study can be used to monitor and provide ecological-health hazards of potentially toxic metals in the Klang mangrove ecosystem to lessen the threats to the ecosystem. Using the current findings to manage the Klang mangrove ecosystem, a water-energy-food framework can be proposed. Abstract This study aimed to evaluate the ecological-health risks of potentially toxic metals in the surface sediments on the Klang mangrove ecosystem and assessed the phytoremediation potential of Avicennia officinalis collected from the area. The results showed that the concentrations (mg/kg dry weight) of Cu, Ni, Pb and Zn in the surface sediments ranged between 5.30–63.8, 14.2–32.7, 30.3–62.3, and 46.4–269, respectively. The ecological risk values of the surface sediments indicated that Ni, Pb and Zn were all classified as ‘low potential ecological risk’, while the Cu ecological risk ranged between ‘low potential ecological risk’ and ‘considerable potential ecological risk’. For the health risks on the sediments, all of the values of hazard index for Cu, Ni, Pb and Zn, based on a combination of three pathways, indicated < 1.00, showing that the four metals are non-carcinogenic. Based on the bioconcentration factor values, it can be concluded that the lamina has better potential as a phytoremediator of essential Cu, Zn and Fe. In contrast, midrib plus petiole has better potential as a phytoremediator of non-essential Pb and Ni. To mitigate the threats to the Klang mangrove ecosystem, the information offered in the present study can be employed in the monitoring and provision of the ecological-health risks of potentially toxic metals in the Klang mangrove ecosystem. Hence, the present findings can be employed for developing a water-energy-food framework for managing the Klang mangrove ecosystem.
THREE-DIMENSIONAL LAMINAR AND TURBULENT NATURAL CONVECTION IN A CONTINUOUSLY/DISCRETELY WALL-HEATED ENCLOSURE CONTAINING A THERMAL LOAD

An experimentally motivated numerical simulation of three-dimensional natural convection in a heated enclosure containing a discrete thermal load has been performed. A special feature of the simulation is the use of the actual equation of state of air, in contradistinction to the customary Boussinesq model. Heating is accomplished continuously at all the walls of the enclosure and by a discrete, rod-like heater situated at the enclosure floor. The bulk of the solutions were carried out for steady laminar flow, but a specific solution for turbulent flow was performed for comparison purposes. By making use of an extended quasi-steady model, the steady-state results were employed to predict the time-varying temperature of the thermal load. The agreement between the numerically based predictions and the experimental data obtained by the authors was very good. For the case selected for the laminar-turbulent comparison, only modest deviations occurred for the heat transfer rates at the surfaces of the load. It was also shown that steady heat transfer rates could prevail at the load surfaces despite the fact that the flow field beneath the load was unsteady.
Multifaceted Benefits of GDF11 Treatment in Spinal Cord Injury: In Vitro and In Vivo Studies

Traumatic spinal cord injury (SCI) initiates a series of cellular and molecular events that include both primary and secondary injury cascades. This secondary cascade provides opportunities for the delivery of therapeutic intervention. Growth differentiation factor 11 (GDF11), a member of the transforming growth factor-β (TGF-β) superfamily, regulates various biological processes in mammals. The effects of GDF11 in the nervous system were not fully elucidated. Here, we perform extensive in vitro and in vivo studies to unravel the effects of GDF11 on spinal cord after injury. In vitro culture studies showed that GDF11 increased the survival of both neuronal and oligodendroglial cells but decreased microglial cells. In stressed cultures, GDF11 effectively inhibited LPS stimulation and also protected neurons from ischemic damage. Intravenous GDF11 administration to rat after eliciting SCI significantly improved hindlimb functional restoration of SCI rats. Reduced neuronal connectivity was evident at 6 weeks post-injury and these deficits were markedly attenuated by GDF11 treatment. Furthermore, SCI-associated oligodendroglial alteration were more preserved by GDF11 treatment. Taken together, GDF11 infusion via intravenous route to SCI rats is beneficial, facilitating its therapeutic application in the future.
Particle-in-cell simulations for the effect of magnetic field strength on a cusped field thruster

The particle-in-cell plus Monte Carlo method is used to simulate a cusped field thruster. Three different values of magnetic field strength are simulated and convergent results are obtained successfully. The simulation results indicate that with the increase of the magnetic field strength, electron density peak tends to move in the radial direction towards the axis of the discharge channel. The central gap area of electron density is decreased due to the stronger electron confinement, which correspondingly reduces the inevitable central electron leak in the cusped field thrusters. However, it is found that the stronger confinement of electrons reduces electron density near the wall, which increases the neutral gas leak there. It is also validated that the main potential drop in the discharge channel appears near the channel exit. With the enhancement of magnetic field strength, potential drops at separatrices increase correspondingly. At the same time, several potential wells and barriers can be found near the wall, which accords well with recent theoretical and experimental results.
Approaches and Vectors for Efficient Cochlear Gene Transfer in Adult Mouse Models

Inner ear gene therapy using adeno-associated viral vectors (AAVs) in neonatal mice can alleviate hearing loss in mouse models of deafness. However, efficient and safe transgene delivery to the adult mouse cochlea is critical for the effectiveness of AAV-mediated therapy. Here, we examined three gene delivery approaches including posterior semicircular canal (PSCC) canalostomy, round window membrane (RWM) injection, and tubing-RWM+PSCC (t-RP) in adult mice. Transduction rates and survival rates of cochlear hair cells were analyzed, hearing function was recorded, AAV distribution in the sagittal brain sections was evaluated, and cochlear histopathologic images were appraised. We found that an injection volume of 1 μL AAV through the PSCC is safe and highly efficient and does not impair hearing function in adult mice, but local injection allows AAV vectors to spread slightly into the brain. We then tested five AAV serotypes (PHP.eB, IE, Anc80L65, AAV2, and PHP.s) in parallel and observed the most robust eGFP expression in inner hair cells, outer hair cells, and spiral ganglion neurons throughout the cochlea after AAV-Anc80L65 injection. Thus, PSCC-injected Anc80L65 provides a foundation for gene therapy in the adult cochlea and will facilitate the development of inner ear gene therapy.
Effect of a Targeted Ambulance Treatment Quality Improvement Programme on Outcomes from Out-of-Hospital Cardiac Arrest: A Metropolitan Citywide Intervention Study

The performance of ambulance crew affects the quality of pre-hospital treatment, which is vital to the survival for out-of-hospital cardiac arrest (OHCA) patients, yet remains suboptimal in China. In this retrospective analysis study, we aimed to examine the effect of a citywide quality improvement programme on provision of prehospital advanced life support (ALS) by emergency medical service (EMS) system. EMS-treated adult OHCA patients after the implementation of the programme (1 January 2021 to 30 June 2022) were compared with historical controls (1 June 2019 to 31 August 2020) in Suzhou. Multivariable logistic regression analysis and propensity score matching procedures were applied to compare the outcomes between two periods for total OHCA cases and subgroup of cases treated by fixed or non-fixed ambulance crews. A total of 1465 patients (pre-period/post-period: 610/855) were included. In the 1:1 matched analysis of 591 cases for each period, significant improvement (p < 0.05) was observed for the proportion of intravenous (IV) access (23.4% vs. 68.2%), advanced airway management (49.2% vs. 57.0%), and return of spontaneous circulation (ROSC) at handover (5.4% vs. 9.0%). The fixed ambulance crews performed better than non-fixed group in IV access and advanced airway management for both periods. There were significant increases in IV access (AOR 12.66, 95%CI 9.02–18.10, p < 0.001), advanced airway management (AOR 1.67, 95% CI 1.30–2.16, p < 0.001) and ROSC at handover (AOR 2.37, 95%CI 1.38–4.23, p = 0.002) after intervention in unfixed group, while no significant improvement was observed in fixed group except for IV access (AOR 7.65, 95%CI 9.02–18.10, p < 0.001). In conclusion, the quality improvement program was positively associated with the provision of prehospital ALS interventions and prehospital ROSC following OHCA. The fixed ambulance crews performed better in critical care provision and prehospital outcome, yet increased protocol adherence and targeted training could fill the underperformance of non-fixed crews efficaciously.
Leaf UV-B Irradiation and Mycorrhizal Symbionts Affect Lettuce VOC Emissions and Defence Mechanisms, but Not Aphid Feeding Preferences

Simple Summary Arbuscular mycorrhizal fungi (AMF), as well as ultraviolet-B radiation (UV-B), could act as key factors affecting plant–insect interactions. The stress related to one of these two factors could be balanced by the positive effects of the other. In the present work, the feeding preferences of Myzus persicae aphids for lettuce plants exposed to two abiotic factors, i.e., AMF and UV-B, singly or in combination, was evaluated. Results showed that lettuce plants treated with UV-B increased in callose and oxidative stress indicators, signalling an alteration in the volatile organic compounds (VOCs) emitted. On the other hand, the negative effects of UV-B were partially mitigated in lettuces inoculated with AMF. Differently treated lettuces did not affect the feeding preferences of the M. persicae aphid population. Overall, this study shed light on how UV-B and AMF impact lettuce VOCs emission and defence mechanisms, but not the feeding behaviour of a polyphagous aphid species. Abstract Arbuscular mycorrhizal fungi (AMF) and ultraviolet-B radiation (UV-B) play important roles in plant–insect interactions by altering plant physiology and histology. We hypothesized that UV-B-induced oxidative stress was mitigated by AMF symbiosis. In this study, we conducted a multifactorial experiment to explore lettuce plant response to AMF inoculation and UV-B exposure (0.4 W m−2; 16 h d−1; 2 weeks), either together or individually, as well as the interaction with the polyphagous insect pest Myzus persicae (Sulzer). Lettuce plants subjected to UV-B radiation showed an increase in callose and oxidative stress indicators, as well as a decrease in stomatal density. Mycorrhizal colonization cancelled out the effect of UV-B on stomatal density, while the symbiosis was not affected by UV-B treatment. The plant volatile emission was significantly altered by UV-B treatment. Specifically, the non-terpene 1-undecene abundance (+M/+UVB: 48.0 ± 7.78%; −M/+UVB: 56.6 ± 14.90%) was increased, whereas the content of the non-terpene aldehydes decanal (+M/+UVB: 8.50 ± 3.90%; −M/+UVB: 8.0 ± 4.87%) and undecanal (+M/+UVB: 2.1 ± 0.65%; −M/+UVB: 1.20 ± 1.18%) and the sesquiterpene hydrocarbons (+M/+UVB: 18.0 ± 9.62 %; −M/+UVB: 19.2 ± 5.90%) was decreased. Mycorrhization, on the other hand, had no significant effect on the plant volatilome, regardless of UV-B treatment. Aphid population was unaffected by any of the treatments, implying a neutral plant response. Overall, this study provides new insights about the interactions among plants, UV-B, and AMF, outlining their limited impact on a polyphagous insect pest.
Assessment of health sciences academic advisors’ mental health literacy and their experiences with students facing mental health problems

Background Owing to everyday educational activities, academic advisors often have to deal with mental health problems among students. Therefore, their mental health literacy must be assessed to determine whether they can detect mental health problems when working with the students. Objective This study aimed to assess health sciences academic advisors’ mental health literacy and their experiences dealing with university students facing mental health challenges. Methods A cross-sectional descriptive study was undertaken among a convenience sample of 133 health sciences academic advisors at the medical campus of a public university in Jeddah, Saudi Arabia. An electronic self-administered questionnaire using the Mental Health Literacy Scale (MHLS) was used to appraise participants’ recognition, knowledge, and attitudes toward ways to solve mental health difficulties. Data collection was completed from November 2020 to February 2021. Descriptive statistics, Student’s t-test for independent samples, One-Way Analysis of Variance (ANOVA), and Tukey’s test were selected for data analysis. Results Academic advisors were found to be highly literate about matters of mental health. The mean mental health literacy score was statistically significantly higher in those advisors who were lecturers, assistant professors, associate professors, and professors (p <0.001). Additionally, the mean scores were significantly higher among advisors with a teaching role of lecturer rather than those who did not have the teaching role of a clinical supervisor (t = -2.331; p = 0.021). Conclusions The academic advisors had an elevated level of mental health literacy, and the highly experienced academic advisors could deal better with students having mental health problems. Hence, it is essential to continue to provide educational programs and training on mental health literacy to academic advisors, as it helps them identify the signs of mental health complications. Furthermore, it improves their skills and confidence when they offer student support in coping with mental health issues.
Detection of compact radio emission from Circinus X-1 with the first Southern hemisphere e-VLBI experiment

Circinus X-1 has recently returned to a state of strong radio flaring. Here we report on the first VLBI observations, and detection, undertaken in the 25 years since the 1975–1985 period of strong recurrent flaring activity.We detected Circinus X-1 with the first observations conducted by a recently developed Southern hemisphere e-VLBI array, at both 1.6 and 8.4 GHz, over a three-day period. At 1.6 GHz, the compact source has a total flux density of 11 mJy and a size of 60 ± 15 mas (Gaussian model full width at half maximum). At 8.4 GHz, the compact source is less than 60 mas. The size variation with frequency is consistent with a broadened image due to scattering in the turbulent, ionized interstellar medium of our Galaxy. However, these size measurements appear inconsistent with the λ2. 2 variation expected for strong interstellar scattering and previous VLBI observations made at 2.3 GHz in the early 1980s. To explain this apparent inconsistency, we suggest that Circinus X-1 supports a weak, non-varying component of 35 mas extent (175 au at 5 kpc distance), corresponding to compact structure in the extended radio nebula. No significant variation in the flux density at 1.6 GHz is evident between two observations 24 h apart. No jet-like structures are evident on scales of tens of mas, simply a scatter broadened source, presumably coincident with the suggested neutron star in the binary system.
Muhammad in The West: Analysis of the Historical Description of the Prophet Muhammad in Armstrong’s Writings

The main objectives of this study are to analyze and understand: (1) the general constructions of the Prophet Muhammad in the descriptions of Western writers; and (2) Armstrong's description of the Prophet Muhammad. This study is library research that uses a qualitative approach with a descriptive-critical method. Data were collected by reading various biographical literature on Prophet Muhammad from Western writers, which were grouped into three criteria: orientalist writers, revisionist writers, and popular writers. The results of the study show that: (1) there is a dynamic dialectic in the description of the figure of the Prophet Muhammad by Western writers, both from orientalist circles, such as W. Montgomery Watt, David Samuel Margoliouth, Edward Said, revisionists such as Patricia Crone, Michael Cook, Fred M. Donner, and popular writers like Karen Armstrong. This dynamic shows that the effort to understand the figure of the Prophet Muhammad is an important effort to understand Islam in Western society; and (2) Armstrong's description as the author of popular religious studies books about the figure of the Prophet Muhammad; made a major contribution to reducing various misunderstandings about Islam and the figure of the Prophet Muhammad in the eyes of Western society.
Carbon, nitrogen, and oxygen abundances in the chemically peculiar stars of the upper main sequence

Low-noise, high-resolution Reticon spectra are used to obtain C, N, and O abundances for chemically peculiar stars with surface temperatures between 7,000 and 15,000 K. The analysis includes C I, C II, N I, and O I lines for 13 Am and related stars, nine Hg-Mn stars, 15 magnetic Ap stars, and five standard stars. The C and O abundances show a roughly monotonic increase with surface temperature. The C and O results are in general agreement with radiative diffusion theory. The N abundances, however, show that N is slightly deficient in cool nonmagnetic stars and very deficient above 10,000 K in nonmagnetic stars. The results for N disagree with simple diffusion predictions, suggesting that a more detailed model is needed for partially ionized N near the stellar surface. 101 refs.
Sub-Surface Analysis of Grinding Burns with Barkhausen Noise Measurements

Barkhausen noise (BN) measurements are commonly used for surface characterisation. However, often there is also a need to verify the sub-surface region because detrimental tensile stresses may be present after different manufacturing steps. Especially in a grinding burn, the surface stress may be compressive, but it changes quickly into tensile stress below the surface. The aim of this study was to find out whether regular surface-sensitive BN measurement is also sensitive to the stresses below the surface caused by grinding burns. More specifically, the aim was to study the relationship between BN features and sub-surface stresses and to identify a model that estimates sub-surface stresses. Real samples were collected from an actual process. The samples were cylindrical samples manufactured from commercial alloyed AISI/SAE L6 steel that was through-hardened prior to grinding. Barkhausen noise measurements were carried out for 42 grinding burn locations followed by X-ray diffraction-based residual stress surface measurements and residual stress depth profiles. Depth information was obtained through step-by-step electrolytic removal of thin layers. The stress profiles were pre-processed through interpolation and averaged stress was calculated as a function of depth below the surface. Correlation analysis was carried out to evaluate the relationships between BN features and stress at different depths and among BN features. The main outcome of the analysis was that BN measurement is dominated by the sub-surface tensile stresses rather than the compressive stress at the surface. It was also noticed that BN features form two groups, corresponding to average Barkhausen activity and magnetising field strength leading to maximum Barkhausen activity. Models for stress at different steps were identified systematically. The performance of the models for sub-surface stresses was reasonable with R2 values of around 0.85 and root mean squared error (RMSE) values of around 95 MPa. Based on the results, it is concluded that BN measurement provides information about sub-surface stresses and that stress can be evaluated through straightforward modelling, allowing fast detection of grinding burns.
LEARNING STYLES PROFILE AND THEIR IMPACT ON LEARNING BEHAVIOR OF ISLAMIC GUIDANCE AND COUNSELING STUDENTS DURING PANDEMIC

Online learning has followed the learner's modality/learning style. In the context of educational psychology, learning styles have to do with the uniqueness or differences of individuals in learning. Problems that occur when the learning process is not following the learning style are emotional problems, self-efficacy, motivation, etc. This descriptive study aimed to generate a profile of learning styles on research samples, platforms that were often used during online learning, as the trend of learning activities of the samples. Thus, researchers could analyze the relationship between those three variables. The study population and sample were 120 guidance and counseling study program students in the 6th semester. This research used questionnaires as research instruments. The results showed that online learning during the pandemic was not following student learning styles in Islamic guidance and counseling programs, so it had an impact on students’ burnout and learning procrastination. Kinesthetic learning style was the learning style that most respondents had (49.17%). Meanwhile, the learning activity that was often carried out was listening through Zoom meetings. This mismatch had an impact on student interaction, engagement, interests, and motivation. Guidance and counseling courses could emphasize project-based learning activities using the TPACK model. Thus, students could conduct experiments collaboratively with diverse learning styles.
