Abstract

In March 2022, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. The phylum was expanded by two new families (bunyaviral Discoviridae and Tulasviridae), 41 new genera, and 98 new species. Three hundred forty-nine species were renamed and/or moved. The accidentally misspelled names of seven species were corrected. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.

Abstract

Purpose: This paper aims to address a gap in investigating specific impacts of climate change on mental health in the Pacific region, a region prone to extreme events. This paper reports on a study on the connections between climate change, public health, extreme weather and climate events (EWEs), livelihoods and mental health, focusing on the Pacific region Islands countries. Design/methodology/approach: This paper deploys two main methods. The first is a bibliometric analysis to understand the state of the literature. For example, the input data for term co-occurrence analysis using VOSviewer is bibliometric data of publications downloaded from Scopus. The second method describes case studies, which outline some of the EWEs the region has faced, which have also impacted mental health. Findings: The results suggest that the increased frequency of EWEs in the region contributes to a greater incidence of mental health problems. These, in turn, are associated with a relatively low level of resilience and greater vulnerability. The findings illustrate the need for improvements in the public health systems of Pacific nations so that they are in a better position to cope with the pressures posed by a changing environment. Originality/value: This paper contributes to the current literature by identifying the links between climate change, extreme events, environmental health and mental health consequences in the Pacific Region. It calls for greater awareness of the subject matter of mental health among public health professionals so that they may be better able to recognise the symptoms and relate them to their climate-related causes and co-determinant factors.

70. A comprehensive physicochemical characterization of zinc oxide nanoparticles extracted from sunscreens and wastewaters

Author

Khan, AUH, Liu, Y, Fang, C, Naidu, R, Shon, HK, Rogers, Z, Dharmarajan, R, Khan, AUH, Liu, Y, Fang, C, Naidu, R, Shon, HK, Rogers, Z, and Dharmarajan, R

Abstract

The widespread popularity of sunscreens contributes significantly to the release of zinc oxide (ZnO) nanoparticles into bodies of water, yet there is still lack of sufficient understanding on the realistic behaviour and long-term exposure. In this study, a simple and effective method was used to extract ZnO nanoparticles from ZnO-based sunscreen products (available in Australia) that end up in wastewaters. The extracted ZnO nanoparticles were negative charged at controlled pH 7. Transmission electron microscopy (TEM) analysis revealed an irregular, spherical and rod-shaped nanoparticles extracted from sunscreens and wastewaters with size ≥100 nm. Various nanoparticles containingZnO, iron, silver, and titanium were detected in wastewater samples collected from treatment plants. Other contaminants were also found in the wastewater samples based on TEM elemental analysis. The results documented in this study are useful to understand the presence and characterizations of ZnO nanoparticles in sunscreens and wastewaters. With this knowledge, we can realistically investigate the fate, behaviours and adverse effects of ZnO nanoparticles.

Abstract

Groundwater protection and contaminated site remediation efforts continue to be hampered by the difficulty in characterizing physical properties in the subsurface at a resolution that is sufficiently high for practical investigations. For example, conventional well-based field methods, such as pumping tests, have proven to be of limited effectiveness for obtaining information, such as the transmissive and storage characteristics of a formation and the rate at which groundwater flows, across different layers in a heterogeneous aquifer system. In this chapter, we describe a series of developments that are intended to improve our discipline’s capability for high-resolution characterization of subsurface conditions in shallow, unconsolidated settings. These developments include high-resolution methods for hydraulic conductivity (K) characterization based on direct push (DP) technology (e.g., DP electrical conductivity probe, DP permeameter, DP injection logger, Hydraulic Profiling Tool (HPT), and High-Resolution K tool), K and porosity characterization by nuclear magnetic resonance (NMR), and groundwater flux characterization by monitoring the movement of thermal or chemical tracers through distributed temperature sensing (DTS) equipment or the point velocity probe (PVP). Each of these approaches is illustrated using field or laboratory examples, and a brief discussion is provided on their advantages, limitations, as well as suggestions for future developments.

Abstract

In this technological world, AI became part of our daily life. In some Restaurants Robots are being used as waiters to serve the meal. This work shows the basic development of a restaurant serving robot using remote sensing mapping robot navigation, with the robot programmed to arrive at a certain table. Vision of The Robot is Usb cam and Kinect V2 sensor to identify the objects. A slam Algorithm is developed to move to the desired table position, and then returns to the service counter once the work is completed. The robot has ultrasonic sensors that detect obstacles and serve as a warning signal to the robot. A vacuum cleaner is designed alongside a robot for mopping and cleaning the floor. This paper studies the potential of a remotely actuated 3-DOF robotic arm equipped with a 2 fingers soft gripper. The robot can also speak to customers in English, saying things like "Welcome," "Please enjoy your food,". The robot arm is simulated using the Robo Analyzer and MATLAB Software.

Abstract

The automobile's skeletal base frame structure, the chassis is responsible for carrying all of the vehicle's weight and supporting loads. Shock, twist, vibration, and other stresses must be absorbed by the chassis. Having adequate bending stiffness is an important consideration in chassis design, as it improves the vehicle's handling. Assembled with axles and a suspension system, a ladder frame chassis acts as a cohesive block to absorb stresses. An ANSYS simulation tool is used to perform structural and random vibration analyses for the theoretically calculated loading conditions. Simulated loading conditions are applied to the C cross-section chassis design. Various steels, such as A710, A4130, ST-52, structural steel, mild steel and wrought iron, are compared to determine the body's dynamic stability. Stability and damping characteristics provided by cross members and leaf springs are typically overlooked in structural analyses of single-frame chassis. Pre-defined loads and random vibrations are used in this study to evaluate the dynamic stability characteristics of the structure. Ladder-frame chassis design must integrate the axles and suspension system into a skeletal design in order to achieve this. The random vibration analysis when carried out resulted in the maximum stress is 300.82GPa in Mild Steel, while the minimum stress is identified as 139.6GPa in A710 Steel. The stresses induced are also less in A710 steel which is recommended when subjected to dynamic loading conditions. [ABSTRACT FROM AUTHOR]

Abstract

The nutritional seeds from Macrotyloma uniflorum (MU) were studied for their unexplored beneficial effect in kidney diseases. Thus, the present study was designed to investigate the MU seed for its nephroprotective efficacy against cisplatininduced nephrotoxicity in an animal model. The nephroprotective potential for the Macrotyloma uniflorum seed extract (MUSE) was evaluated in albino rats (250 and 500 mg/kg; p.o.) for 10 days. At the end of the study, the nephroprotective effect was assessed based on the levels of various biochemical parameters of serum, urine, and kidney tissue. The GC-MS analyses of extract confirmed the antioxidant phytochemical constituents responsible for the nephroprotective activity. The MUSE treatment at 250 and 500 mg/kg p.o. showed a significant reduction in the levels of blood urea nitrogen (p<0.05), serum creatinine (p<0.01), serum urea (p<0.001), restore the urine volume (p<0.01), and urine creatinine (p<0.01) as compared to the negative control (cisplatin-injected rats). Subsequently, the abnormal conditions of creatinine clearance (p<0.05) and serum albumin (p<0.05) were restored to normal. For respective doses of 250 and 500 mg/kg p.o, the superoxide dismutase activity increased (p<0.05) to 82.91 and 98.8 U/g whilst the glutathione level significantly increased (p<0.01) to 36.24 and 46.17 µg/mg. Similarly, the catalase activity was significantly improved (p<0.001) to 485.9 and 573.5 µM/g with a significant reduction (p<0.001) in the level of the malondialdehyde to 84.56 and 68.56 nM/mg, respectively for low and high doses. The histopathology of kidney tissues confirmed the pronounced nephroprotection effect of MUSE against the cisplatin-induced injuries like tubular necrosis, hyaline cast, and vascular congestions. The major constituents found in GC-MS were inositol, ethyl alpha-d-glucopyranoside, n-hexadecanoic acid, 9, 12-octadecadienoic aci, 3-betastigmast-5-en-3-ol, Vitamin E, and stigmasterol. The results indicate the promising nephroprotective potential of Macrotyloma uniflorum seeds in nephrotoxicity induced rats, and the efficacy was comparable with vitamin E. [ABSTRACT FROM AUTHOR]

Abstract

In March 2021, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. The phylum was expanded by four families (Aliusviridae, Crepuscuviridae, Myriaviridae, and Natareviridae), three subfamilies (Alpharhabdovirinae, Betarhabdovirinae, and Gammarhabdovirinae), 42 genera, and 200 species. Thirty-nine species were renamed and/or moved and seven species were abolished. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.

Abstract

Before the end of the Epoch of Reionization, the Hydrogen in the Universe was predominantly neutral. This leads to a strong attenuation of Ly alpha lines of z greater than or similar to 6 galaxies in the intergalactic medium. Nevertheless, Ly alpha has been detected up to very high redshifts (z similar to 9) for several especially UV luminous galaxies. Here, we test to what extent the galaxy's local environment might impact the Ly alpha transmission of such sources. We present an analysis of dedicated Hubble Space Telescope (HST) imaging in the CANDELS/EGS field to search for fainter neighbours around three of the most UV luminous and most distant spectroscopically confirmed Ly alpha emitters: EGS-zs8-1, EGS-zs8-2, and EGSY-z8p7 at z(spec) = 7.73, 7.48, and 8.68, respectively. We combine the multiwavelength HST imaging with Spitzer data to reliably select z similar to 7-9 galaxies around the central, UV-luminous sources. In all cases, we find a clear enhancement of neighbouring galaxies compared to the expected number in a blank field (by a factor similar to 3-9x). Our analysis thus reveals ubiquitous overdensities around luminous Ly alpha emitting sources in the heart of the cosmic reionization epoch. We show that our results are in excellent agreement with expectations from the Dragons simulation, confirming the theoretical prediction that the first ionized bubbles preferentially formed in overdense regions. While three UV luminous galaxies already have spectroscopic redshifts, the majority of the remaining fainter, surrounding sources are yet to be confirmed via spectroscopy. JWST follow-up observations of the neighbouring galaxies identified here will thus be needed to confirm their physical association and to map out the ionized regions produced by these sources.

We describe the LSS care journey from initial diagnosis to first surgical intervention.Methods: Using Medicare claims database from 2009 through 2020, we identified patients who were diagnosed with LSS. The use and timing of conservative and surgical treatments during the entire follow-up from the initial diagnosis were reported.Results: Of the 143,849 patients identified, 68% received conservative care within 8.4 months and 25.3% received a surgical or minimally invasive intervention over 5.7 years following initial diagnosis, with 12.6% undergoing open decompression alone, 10.2% undergoing open decompression with fusion, and 5.1% undergoing fusion surgery alone. Fewer than 1% were provided with interspinous spacers or a percutaneous image-guided lumbar decompression.Conclusion: Approximately three-quarters of patients in the study received no surgical or non-invasive interventions for approximately six years following diagnosis with LSS.Keywords: lumbar spinal stenosis, interspinous spacer, lumbar decompression, chronic pain

Abstract

In March 2020, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. At the genus rank, 20 new genera were added, two were deleted, one was moved, and three were renamed. At the species rank, 160 species were added, four were deleted, ten were moved and renamed, and 30 species were renamed. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.

Abstract

This project details about the Electric Bike which runs on the battery thereby providing voltage to the motor. This project compromises with design and fabrication of Electric Bike which makes use of Electric energy as the primary source and solar energy, if possible, by attaching solar panels. It also highlights on the design aspects of the bike. There is a provision for a charging the battery by ejecting it from the main system. The electrical power generated which is used to run the bike can give better fuel economy compared to conventional vehicle, better performance and also causes less pollution. The project is to design a feasible yet highly adaptable E-bike. As the number of motor vehicles on the roads throughout the world increases at staggering rate each year, the dependence on oil-based fuel grows almost unchecked. The increased use of non-renewable fossil fuels brings with it environmental problems such as: the “greenhouse effect”, health problems for city delivers and concern over the stability of fuel supply. To move away from this dependence on oil, a vast amount of money is being spent on the development of electrical vehicles (EVs) that may be produced. This project presents a study of electrical motorcycle design. The aim of this study is to investigate how to design a simple, cost-effective model of electrical motorcycle with intelligent control system. This can be implemented by removing the internal combustion engine, the exhaust system and other unnecessary components from the motorcycle and replaced by an electrical motor, an intelligent controller.

Abstract

BACKGROUND: Staphylococcus aureus bacteraemia (SAB) is one of the commonest bloodstream infections globally and is associated with a high mortality rate. Most published data comes from temperate, high-income countries. We describe the clinical epidemiology, microbiology, management and outcomes of patients with SAB treated in a tropical, middle-income setting at Fiji's largest hospital. METHODS: A prospective, observational study was performed of consecutive SAB cases admitted to Colonial War Memorial Hospital (CWMH) in Suva, between July 2020 and February 2021. Detailed demographic, clinical and microbiological data were collected, including the key outcome of in-patient mortality. To estimate the population incidence, all SAB cases diagnosed at the CWMH laboratory were included - even if not admitted to CWMH - with the population of Fiji's Central Division used as the denominator. FINDINGS: A total of 176 cases of SAB were detected over eight-months, which equated to an incidence of 68.8 cases per 100,000 population per year. Of these, 95 cases were admitted to CWMH within 48 h of index culture. Approximately 8.4% (8/95) of admitted cases were caused by methicillin-resistant Staphylococcus aureus (MRSA). All cause in-patient mortality was 25.3%, increasing to 55% among patients aged 60 or older. INTERPRETATION: This reported incidence of SAB in central Fiji is one of the highest in the world. SAB was associated with significant mortality, especially in those over 60 years of age, despite a relatively low frequency of methicillin resistance. FUNDING: Supported by the National Health and Medical Research Council (Australia) and the GRAM (Global Research on Antimicrobial Resistance) Project, Oxford University (United Kingdom).

Abstract

Development of polymeric magnetic adsorbents is a promising approach to obtain efficient treatment of contaminated water. However, the synthesis of magnetic composites involving multiple components frequently involves tedious preparation steps. In the present study, a magnetic chitosan-palygorskite (MCP) nanocomposite was prepared through a straight-forward one pot synthesis approach to evaluate its lead (Pb2+) removal capacity from aqueous solution. The nano-architectural and physicochemical properties of the newly-developed MCP composite were described via micro- and nano-morphological analyses, and crystallinity, surface porosity and magnetic susceptibility measurements. The MCP nanocomposite was capable to remove up to 58.5 mg Pb2+ g−1 of MCP from water with a good agreement of experimental data to the Langmuir isotherm model (R2 = 0.98). The Pb2+ adsorption process on MCP was a multistep diffusion-controlled phenomenon evidenced by the well-fitting of kinetic adsorption data to the intra-particle diffusion model (R2 = 0.96). Thermodynamic analysis suggested that the adsorption process at low Pb2+ concentration was controlled by chemisorption, whereas that at high Pb2+ concentration was dominated by physical adsorption. X-ray photoelectron and Fourier transform infrared spectroscopy results suggested that the Pb adsorption on MCP was governed by surface complexation and chemical reduction mechanisms. During regeneration, the MCP retained 82% Pb2+ adsorption capacity following four adsorption–desorption cycles with ease to recover the adsorbent using its strong magnetic property. These findings highlight the enhanced structural properties of the easily-prepared nanocomposite which holds outstanding potential to be used as an inexpensive and green adsorbent for remediating Pb2+ contaminated water.

Abstract

OBJECTIVES: There are scant primary clinical data on antimicrobial resistance (AMR) burden from low- and middle-income countries (LMICs). We adapted recent World Health Organization methodology to measure the effect of third-generation cephalosporin resistance (3GC-R) on mortality and excess length of hospital stay in Fiji. METHODS: We conducted a prospective cohort study of inpatients with Enterobacterales bloodstream infections (BSIs) at Colonial War Memorial Hospital, Suva. We used cause-specific Cox proportional hazards models to estimate the effect of 3GC-R on the daily risk (hazard) of in-hospital mortality and being discharged alive (competing risks), and we used multistate modelling to estimate the excess length of hospital stay. RESULTS: From July 2020 to February 2021 we identified 162 consecutive Enterobacterales BSIs; 3GC-R was present in 66 (40.7%). Crude mortality for patients with 3GC-susceptible and 3GC-R BSIs was 16.7% (16/96) and 30.3% (20/66), respectively. 3GC-R was not associated with the in-hospital mortality hazard rate (adjusted hazard ratio [aHR] 1.13, 95% confidence interval [CI] 0.51-2.53) or being discharged alive (aHR 0.99, 95% CI 0.65-1.50), whereas Charlson comorbidity index score (aHR 1.62, 95% CI 1.36-1.93) and Pitt bacteraemia score (aHR 3.57, 95% CI 1.31-9.71) were both associated with an increased hazard rate of in-hospital mortality. 3GC-R was associated with an increased length of stay of 2.6 days (95% CI 2.5-2.8). 3GC-R was more common among hospital-associated infections, but genomics did not identify clonal transmission. CONCLUSION: Patients with Enterobacterales BSIs in Fiji had high mortality. There were high rates of 3GC-R, which was associated with increased hospital length of stay but not with in-hospital mortality.
