Evaluation of Telehealth Use in Pediatric University Hospitals during the COVID-19 Pandemic

Introduction: During the COVID-19 pandemic, a marked increase in the use of telehealth was observed. However, the recent popularity of these practices in an emergency setting has not resulted in a standardized practice framework for the hospital, leading to diverse practices. In a perspective of continuous improvement, we conducted an assessment of telehealth use within seven international pediatric centers. The aim of this study was to bring out the operational reality on feasibility, medical practice within a protective regulatory framework, and draw out the barriers and challenges in pediatric telehealth practice. Materials and Method: The Health Technology Assessment Unit of Sainte Justine University Hospital Center conducted a benchmarking on seven international centers with similar care organization. An online questionnaire (Appendix 1) was developed for the telehealth managers of each identified center. Results: The COVID-19 pandemic has changed the governance structure of telehealth in three institutions. Main aspects were related to software installation, organization of telehealth in the institution, and institutional use policy and legislation. As for the barriers, the availability of equipment and the use of technology were the most frequently mentioned barriers. Discussion: several institutions changed their telehealth policies. These results can be explained by the temporary closure of some non-emergency hospital services during the pandemic in order to manage patients with COVID-19. Follow-up of patients who could not be followed up in person could be done remotely by teleconsultation. Overall, the majority of centers that responded to the questionnaire were satisfied with the management of telehealth during the pandemic.
Effect of Chemical Treated Okra Waste for Heavy Metal Adsorption from Natural Gas Production Wastewater

Nowadays, one of the leading environmental pollutants is heavy metals. Hence, heavy metals in wastewater must be removed before discharge because they are toxic even at low concentrations. This research aims to evaluate the efficiency of okra waste as an adsorbent for heavy metals removal from wastewater in natural gas production. In this study, chemical activation of okra adsorbent was processed to increase the surface area of okra adsorbent for better adsorption, whenever the impregnation of the powdered okra waste was performed using phosphoric acid (H 3 PO 4 ) as the impregnating agent. The okra powder was impregnated at a rate of 4: 1 (v / m). The FTIR was used to characterize the okra-activated carbon and the peaks showed the presence of functional groups such as Hydroxyl (OH), Amino (N-H), Carboxyl (C=O, C-O-C), C-0 stretching and M-O at 3390.05, 2905.5, 1640-1658, 1050.05 and 650 stretching bands respectively. Furthermore, the batch adsorption experiments were conducted via varying agitation speed, contact time, adsorbent dose and adsorbent particle sizes. The results showed that the maximum removal percent of Cd 2+ , Cu 2+ , Pb 2+ , Zn 2+ , Ag 2+ and Ba 2+ metal ions had been observed to be at an agitation speed of 1000 rpm, contact time of 90 min, okra adsorbent dose of 0.25 g and particle size of 1.00mm. Indeed, the okra adsorbent showed a very high adsorption capacity for Cu 2+ at 14.8 mg/g, followed by Pb 2+ , Zn 2+ and Cd 2+ at 8.37 mg/g, 7.09 mg/g and 1.79 mg/g mg/g respectively and the 𝑅 𝐿 value in the present study for Cd 2+ , Cu 2+ , Pb 2+ and Zn 2+ ions were found to be 0.0003, 0.0027, 0.0001 and 0.0002 respectively. Therefore, all values of R L were less than one, indicating that the adsorption of these heavy metal ions onto okra adsorbent was favorable. The experimental findings show that okra wastes from agricultural by-products may be a low-cost adsorbent for future research to remove additional heavy metals owing to their high effectiveness in removing Cd 2+ , Cu 2+ , Pb 2+ , and Zn 2+ ions from wastewater.

GEOCHEMICAL CHARACTERIZATION OF MINE WASTE FROM THE PIKE HILL SUPERFUND SITE IN VERMONT, USA 1

The Pike Hill mines Superfund site consists of a group of mines that worked copper-rich Besshi-type massive sulfide deposits. The site contains the abandoned Smith, Eureka, and Union mines and was listed in 2004 as a Superfund site due to aquatic ecosystem impacts. This study is part of a larger project that includes mine waste characterization, surface-water geochemical studies, and documentation of downstream impacts on biota. It is intended to be a precursor to a formal remedial investigation by the U.S. Environmental Protection Agency (USEPA). The goal of this paper is to provide a relative comparison of the various waste piles through characterization of bulk geochemistry, mineralogy, paste pH, acid-base accounting, and metal leachability. In addition, results were compared to similar studies of mine waste from the nearby Ely and Elizabeth Superfund sites. Mine-waste samples at the Pike Hill mines include flotation-mill tailings and waste rock that is composed of fine-grained to boulder- sized host rock and mineralized rock. The waste is primarily composed of silicates, oxides, sulfates, and sulfides, including pyrrhotite, pyrite, chalcopyrite, and sphalerite. Samples locally contain native sulfur and calcite; efflorescent sulfate salts have been observed on waste piles and adit walls. Composite mine- waste samples contain concentrations of Cd, Cu, and Fe that exceed USEPA Preliminary Remediation Goals (PRGs). The concentrations of Se are elevated relative to the average composition of eastern U.S. soils. All mine-waste samples, except the processed flotation-mill tailings, which contain calcite, have paste pH values of 4 or less and negative net-neutralization potentials indicating the samples are acid generating. Twenty-four-hour leachate tests, which use a solution that approximates eastern U.S. precipitation, indicate that potentially toxic trace elements and acidity can be released under simulated weathering conditions. Mine waste at Pike Hill mines is chemically and mineralogically similar to that at the Elizabeth and Ely mines. Also, metals are leached and acid produced in comparable concentrations. Based on the results of this study, mine waste at the Pike Hill Superfund site contaminates soils, is acid generating, and may release potentially toxic metals to streams.
Hydrodynamic coupling in microbially mediated fracture mineralization: Formation of self‐organized groundwater flow channels

Evidence of fossilized microorganisms embedded within mineral veins and mineral‐filled fractures has been observed in a wide range of geological environments. Microorganisms can act as sites for mineral nucleation and also contribute to mineral precipitation by inducing local geochemical changes. In this study, we explore fundamental controls on microbially induced mineralization in rock fractures. Specifically, we systematically investigate the influence of hydrodynamics (velocity, flow rate, and aperture) on microbially mediated calcite precipitation. Our experimental results demonstrate that a feedback mechanism exists between the gradual reduction in fracture aperture due to precipitation, and its effect on the local fluid velocity. This feedback results in mineral‐fill distributions that focus flow into a small number of self‐organizing channels that remain open, ultimately controlling the final aperture profile that governs flow within the fracture. This hydrodynamic coupling can explain field observations of discrete groundwater flow channeling within fracture‐fill mineral geometries where strong evidence of microbial activity is reported.
Petrology on Mars

Abstract Petrologic investigations of martian rocks have been accomplished by mineralogical, geochemical, and textural analyses from Mars rovers (with geologic context provided by orbiters), and by laboratory analyses of martian meteorites. Igneous rocks are primarily lavas and volcaniclastic rocks of basaltic composition, and ultramafic cumulates; alkaline rocks are common in ancient terranes and tholeiitic rocks occur in younger terranes, suggesting global magmatic evolution. Relatively uncommon feldspathic rocks represent the ultimate fractionation products, and granitic rocks are unknown. Sedimentary rocks are of both clastic (mudstone, sandstone, conglomerate, all containing significant igneous detritus) and chemical (evaporitic sulfate and less common carbonate) origin. High-silica sediments formed by hydrothermal activity. Sediments on Mars formed from different protoliths and were weathered under different environmental conditions from terrestrial sediments. Metamorphic rocks have only been inferred from orbital remote-sensing measurements. Metabasalt and serpentinite have mineral assemblages consistent with those predicted from low-pressure phase equilibria and likely formed in geothermal systems. Shock effects are common in martian meteorites, and impact breccias are probably widespread in the planet’s crustal rocks. The martian rock cycle during early periods was similar in many respects to that of Earth. However, without plate tectonics Mars did not experience the thermal metamorphism and flux melting associated with subduction, nor deposition in subsided basins and rapid erosion resulting from tectonic uplift. The rock cycle during more recent time has been truncated by desiccation of the planet’s surface and a lower geothermal gradient in its interior. The petrology of Mars is intriguingly different from Earth, but the tried-and-true methods of petrography and geochemistry are clearly translatable to another world.
Microbial Upcycling of Waste PET to Adipic Acid

Microorganisms can be genetically engineered to transform abundant waste feedstocks into value-added small molecules that would otherwise be manufactured from diminishing fossil resources. Herein, we report the first one-pot bio-upcycling of PET plastic waste into the prolific platform petrochemical and nylon precursor adipic acid in the bacterium Escherichia coli. Optimizing heterologous gene expression and enzyme activity enabled increased flux through the de novo pathway, and immobilization of whole cells in alginate hydrogels increased the stability of the rate-limiting enoate reductase BcER. The pathway enzymes were also interfaced with hydrogen gas generated by engineered E. coli DD-2 in combination with a biocompatible Pd catalyst to enable adipic acid synthesis from metabolic cis,cis-muconic acid. Together, these optimizations resulted in a one-pot conversion to adipic acid from terephthalic acid, including terephthalate samples isolated from industrial PET waste and a post-consumer plastic bottle.
Vertical structure of mesoscale eddies in the eastern South Pacific Ocean: A composite analysis from altimetry and Argo profiling floats

[1] The mean vertical structure of mesoscale eddies in the Peru-Chile Current System is investigated by combining the historical records of Argo float profiles and satellite altimetry data. A composite average of 420 (526) profiles acquired by Argo floats that surfaced into cyclonic (anticyclonic) mesoscale eddies allowed constructing the mean three-dimensional eddy structure of the eastern South Pacific Ocean. Key differences in their thermohaline vertical structure were revealed. The core of cyclonic eddies (CEs) is centered at ∼150 m depth within the 25.2–26.0 kg m−3 potential density layer corresponding to the thermocline. In contrast, the core of the anticyclonic eddies (AEs) is located below the thermocline at ∼400 m depth impacting the 26.0–26.8 kg m−3 density layer. This difference was attributed to the mechanisms involved in the eddy formation. While intrathermocline CEs would be formed by instabilities of the surface equatorward coastal currents, the subthermocline AEs are likely to be shed by the subsurface poleward Peru-Chile Undercurrent. In the eddy core, maximum temperature and salinity anomalies are of ±1°C and ±0.1, with positive (negative) values for AEs (CEs). This study also provides new insight into the potential impact of mesoscale eddies for the cross-shore transport of heat and salt in the eastern South Pacific. Considering only the fraction of the water column associated with the fluid trapped within the eddies, each CE and AE has a typical volume anomaly flux of ∼0.1 Sv and yields to a heat and salt transport anomaly of ±1–3 × 1011 W and ±3–8 × 103 kg s−1, respectively.
Measuring Surroundings Awareness using Different Visual Parameters in Virtual Reality

—Due to the popularity of digital games, there is a growing interest in using games as therapeutic interventions. The ability of games to capture attention can be beneficial to distract patients from pain. In this paper, we investigate the impact of visual parameters (color, shapes, and animation) on users’ awareness of their surroundings in virtual reality. We conducted a user study in which experiments included a visual search task using a virtual reality game. Through the game, the participants were asked to find a target among distraction objects. The results showed that the different visual representations of the target among distraction objects could affect the users’ awareness of their surroundings. The least awareness of the surroundings occurred when the target and distractors shared similar features. Further, the conjunction of low similarity between distractors-distractors and high similarity between target-distractors provided less awareness of the surroundings. Additionally, results revealed that there is a strong positive correlation between search time and awareness of the surroundings. Less awareness of the surroundings while playing a game implies that users are positively engaged in that game. These results offered a set of criteria that can be applied to future virtual reality interventions for medical pain distraction.
The Efficacy of Erector Spinae Plane Block for Thoracoscopic Surgery: A Meta-Analysis of Randomized Controlled Trials.

BACKGROUND The efficacy of erector spinae plane block for thoracoscopic surgery remains controversial. We conducted a systematic review and meta-analysis to explore the impact of erector spinae plane block on thoracoscopic surgery. METHODS We searched the PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through February 2022 for randomized controlled trials (RCTs), assessing the effect of erector spinae plane block on thoracoscopic surgery. This meta-analysis was performed using the random-effect model. RESULTS Seven RCTs, involving 439 patients, are included in the meta-analysis. Overall, compared with the control group for thoracoscopic surgery, erector spinae plane block (ESPB) results in significantly reduced pain scores at 1 h (standard mean difference (SMD) = -4.26; 95% confidence interval (CI) = -7.63 to -0.88; p = 0.01), 4 h (SMD = -4.08; 95% CI = -4.56 to -3.60; p < 0.00001), 8 h (SMD = -4.13; 95% CI = -4.62 to -3.65; p < 0.00001), and postoperative anesthesia consumption (SMD = -3.04; 95% CI = -4.58 to -1.50; p = 0.0001) and can decrease the incidence of nausea and vomiting (odd ratio (OR) = 0.18; 95% CI = 0.08 to 0.39; p < 0.001). CONCLUSIONS ESPB can substantially enhance pain relief for thoracoscopic surgery.
Work environment development using cognitive work analysis’ decision ladders.

The study aimed to create decision-making content for workplace work environment development, followed by a limited evaluation to determine the perception of the importance of the identified content in different sectors. Enforcement/administrative orders in workplace inspection reports were used as empirical infor-mation on workplaces. This information was used to design decision ladders, which form the second phase of cognitive work analysis, the activity analysis. The decision ladders, which support decision-making, cov-ered work functions identified in an earlier work domain analysis study, i.e., exposure prevention, organisa-tional management, competence realisation, workers’ empowerment, psychosocial work environment man-agement, and administration. Specified content of decision ladders for each function was used to prepare a questionnaire for evaluating the content validity for work environment development. Altogether, 29 items were identified as the content for work environment development. Statistical analysis of the limited evaluation showed no significant difference between the different sectors in their perceptions of the importance of the content in developing work environments. Similar sectoral perceptions' trends support the content utility and validity in work environment development. The procedure formulation step of the decision ladders, with the phrase “What steps are needed to. ” applied preceding the identified content constructs, provides practical activities regarded as essential for work environment development. Using enforcement inspection reports as the basis for work environment development is a novel approach to addressing workplace safety and health management challenges. Further, the universal utility of the content allows for its implementation across sectors, allowing for workplace-specific decision-making on management measures.
The Quiet Tsunami: The Ecological, Economic, Social, and Political Consequences of Ocean Acidification

A large portion of the carbon dioxide emitted into the atmosphere is absorbed by the world’s oceans. They become more acidic as they absorb the gas. This has far‑reaching implications for the oceanic food-web, biodiversity and the global economy, particularly fishing and ecotourism industries in developing countries. This article briefly outlines the scientific evidence of ocean acidification and the implications of anthropogenic carbon emissions for marine ecosystems. It then assesses the economic, social and political ramifications of ocean acidification and suggests a new strategy for climate change policy. The “quiet tsunami” of oceanic climate change necessitates a policy shift away from the business‑as‑usual approach to reducing carbon emissions. The high stakes involved in this looming crisis may prompt unwilling governments to act in order to ensure food security and protect key economic markets around the world.
ARCSTONE: calibration of lunar spectral reflectance from space. Prototype instrument concept, analysis, and results

Abstract. The ARCSTONE project objective is to acquire accurate measurements of the spectral lunar reflectance from space, allowing the Moon to be used as a high-accuracy SI-traceable calibration reference by spaceborne sensors in low-Earth and geostationary orbits. The required spectral range is 350 to 2300 nm with 4-nm sampling. The ARCSTONE approach is to measure solar and lunar spectral irradiances with a single set of optics and determine spectrally resolved lunar reflectances via a direct ratioing method, eliminating long-term optical degradation effects. Lunar-irradiance values, derived from these direct reflectance measurements, are enabled by independently measured SI-traceable spectral solar irradiances, essentially using the Sun as an on-orbit calibration reference. In an initial attempt to demonstrate this approach, a prototype ultraviolet-visible-near infrared (348 to 910 nm) instrument was designed, fully assembled, characterized, and field tested. Our results demonstrate that this prototype ARCSTONE instrument provides a dynamic range larger than 106, which is necessary to directly measure both the solar and lunar signals, and suggest uncertainties better than 0.5% (k = 1) in measuring lunar spectra can be achieved under proper operational scenarios. We present the design, characterization, and proof-of-concept field-test of the ARCSTONE instrument prototype.

This paper is an exploratory research, based on data and studies on recent evolution of the travelling reasons, in order to identify the changing trends.
The Factors That Influence the Level of Underpricing of Shares in Non-Financial Companies That Conduct IPO (Initial Public Offering) on the Indonesian Stock Exchange

Underpricing is also often defined as the positive difference between the share price in the secondary market and the share price in the primary market or during the initial public offering (IPO). This price difference is known as the initial return (IR) or positive return for investors. Underpricing is a common phenomenon that often occurs in the capital market and when companies conduct an initial public offering (IPO). This research was conducted to analyse the factors that affect the level of stock underpricing in non-financial companies. These factors are Return on assets, financial leverage, underwriter reputation, and company size. The population of this study is non-financial companies that conducted IPOs on the Indonesia Stock Exchange in 2015-2019. Sampling using purposive sampling, namely sample selection with certain criteria, so that 30 companies were obtained as research samples. The research method uses multiple linear regression, classical assumption test, t test and f test. The results showed that only company size has a significant effect on underpricing. While return on assets, financial leverage and underwriter reputation have no significant effect on underpricing. Simultaneously and significantly return on assets, financial leverage, underwriter reputation and company size affect underpricing.
