Water quality and probabilistic non-carcinogenic health risk of groundwater: a half decadal scenario change in Vadodara

Groundwater is essential to secure the safety of water supply in Vadodara, Gujarat. In this study, groundwater samples were collected from various part of the city which separated in 12 wards. The present study contains analyses of 720 groundwater samples gathered from various tube and open wells and analyzed for fluoride and other physicochemical parameters during 2014 and 2019. The results indicated that fluoride and TDS were high and the overall water quality was poor in the study area. Gastrointestinal and other health-related issues increased due to higher TDS in east, north and northeast regions. Likewise, hierarchical cluster analysis also indicated that TDS and chloride-rich water. Fluoride concentration was observed in the range of 0.66-1.61 mg/l (2014) and 0.86-1.77 mg/l (2019) which indicates that 62% samples are unfit for drinking purpose, which could cause dental and skeletal fluorosis. The water quality index (WQI) indicated lack of excellent water in the studied area in the last half-decade. As per WQI calculation suggest that 82.12% (2014) and 69.00% (2019) of groundwater samples represent poor, very poor and unsuitable categories, whereas remaining 17.85% (2014) and 31.00% (2019) of the samples represent good category for drinking purposes in entire Vadodara, Gujarat. Marginal improvement in the groundwater quality is reported due to good rainfall in 2019. Health risks associated with high fluoride drinking water were assessed for various age groups of inhabitants such as children, infants and adults. The non-carcinogenic hazard quotient estimated by oral intake was 1.38-3.36 (2014) and 1.79-3.70 (2019) for infants; 0.69-1.68 (2014) and 0.90-1.85 (2019) for children, whereas 0.07-0.18 (2014) and 0.10-0.20 (2019) for adults. Therefore, infant and children are relatively at higher health risk due to the intake of fluoride-rich drinking water than adult in the studied region. Both indices were indicated contaminated water or closer to contamination which induced non-carcinogenic health risk on citizens. Thus, the comprehensive results of present study can be used as a baseline data and valuable tool for government authorities for long-term monitoring, health monitoring and sustainable development of Vadodara, Gujarat.
Analysis of Pharmacist Interventions in Adult COVID-19 Patients Admitted to a Tertiary Care Hospital

Background: Pharmacists are integral members of the multidisciplinary healthcare team who, with their skills, knowledge, and training, are well positioned to prevent, identify, and manage medication-related issues. Many published articles related to COVID-19 management have highlighted the important role of the pharmacists in assuring the safe, effective, and cost-effective use of medications. During such challenging times of COVID-19 pandemic that resulted in a high demand on medical resources and healthcare providers, pharmacists are well positioned to contribute and add more efforts to the healthcare system to achieve best use of the available resources including medications and providing high quality pharmaceutical care to help the patients and support the healthcare providers. Methods: This is a retrospective chart review included all admitted adult patients with confirmed COVID-19 diagnosis from 1 March 2020 till 30 June 2020. The documented clinical pharmacist interventions were extracted from the EMR and reviewed by multiple clinical pharmacists to identify type, number, frequency, outcome, and physician's acceptance rate of documented interventions. Results: A total of 484 pharmacist interventions included in the final analysis. Antimicrobial stewardship interventions were the most reported (149, 30.8%) and antibiotics were the most reported class of medication, constituting 31.1% of the total interventions. "Optimized therapy" was the most commonly reported outcome (58.8%). Overall, 50.8% (246) of the interventions were rated as having "moderate" clinical significance using the clinical significance scoring tool. The physicians' acceptance rate was 94.7%. Conclusion: Pharmacist interventions are associated with improved communication and medication use in admitted adult patients with COVID-19. Clinical pharmacists can play a crucial role in optimizing medication use in patients with COVID-19 through prevention, identification, and resolving existing or potential drug-related problems.
Long-run system value of battery energy storage in future grids with increasing wind and solar generation

With declining costs of battery storage, there is growing interest to deploy them in power systems to provide multiple grid services that directly support integration of variable renewable energy (VRE) generation. Here, we assess the holistic system value of energy storage in future grids with increasing wind and solar generation. We also identify the major sources of storage value and their dynamics under different system settings and at increasing storage and wind and solar penetration levels. We use a high temporal resolution capacity expansion model to study least-cost integration of storage in two variants of an abstract power system that is populated with load and VRE profiles consistent with the U.S. Northeast (North) and Texas (South) regions. For both systems, storage value originates primarily from deferring investments in generation capacity (VRE, natural gas) and transmission, and generally declines with increasing storage penetration. Increasing VRE penetration from 40% to 60% increases the value of storage, but only enough to make storage capacity up to 4% of peak demand cost-effective at current Lithium-ion capital costs. With future capital costs of $150/kWh for 4 h duration storage, the cost-effective storage penetration ranges between 4% and 16% of peak demand across the system scenarios studied here. Storage substitution of natural gas capacity is dependent on the VRE resource mix and penetration level, but is less than 1 GW per GW of storage added for the durations (2, 4 or 8 h) considered here. Increasing storage duration increases storage value in some cases, but this increase in value may be insufficient to compensate for the increase in capital cost per kW even under the future cost scenario.
Associations between sociodemographic factors, health spending, disease burden, and life expectancy of older adults (70 + years old) in 22 countries in the Western Pacific Region, 1995-2019: estimates from the Global Burden of Disease (GBD) Study 2019

The needs of the aging populations are putting increasing burden on healthcare particularly in the Western Pacific Region (WPR), which is the home of aging economies such as Hong Kong and Japan alongside rapid increases in older people in low- and middle-income countries (LMICs). However, little is known about the associations between sociodemographic factors, disease burden, and life expectancy in WPR. The current study conducted secondary analysis on the Global Burden of Disease (GBD) estimates of populations aged 70 years and older in WPR countries between 1995 and 2019. Correlation tests, linear mixed regressions and generalized additive mixture models were run to examine the associations of interest. Unsupervised machine learning was conducted to segment the data automatically, at cluster analysis. The sociodemographic development index was found an important factor to the disease burden in terms of Years Lived with Disability (YLD) rate and mortality rate among older adults. YLD rate and mortality rate of non-communicable diseases (NCDs) attributable to different risk groups were significant contributors to higher expectation of Lost Healthy Years (LHE) and shorter life expectancy respectively in the context of rising YLD rate, particularly in LMICs. Three clusters of countries with similar characteristics were identified. NCDs were the most significant contributors to shorter life expectancy within which the time living in poor health did not improve. Better management of NCDs in aging populations should be emphasized in all countries. The country clusters may help in a more regional strategic planning.
High Energy Density in Combination with High Cycling Stability in Hybrid Supercapacitors

Hybrid supercapacitors are considered the next-generation energy storage equipment due to their superior performance. In hybrid supercapacitors, battery electrodes need to have large absolute capacities while displaying high cycling stability. However, enhancing areal capacity via decreasing the size of electrode materials results in reductions in cycling stability. To balance the capacity-stability trade-off, rationally designed proper electrode structures are in urgent need and still of great challenge. Here we report a high-capacity and high cycling stability electrode material by developing a nickel phosphate lamination structure with ultrathin nanosheets as building blocks. The nickel phosphate lamination electrode material exhibits a large specific capacity of 473.9 C g-1 (131.6 mAh g-1, 1053 F g-1) at 2.0 A g-1 and only about 21% capacity loss at 15 A g-1 (375 C g-1, 104.2 mAh g-1, 833.3 F g-1) in 6.0 M KOH. Furthermore, hybrid supercapacitors are constructed with nickel phosphate lamination and activated carbon (AC), possessing high energy density (42.1 Wh kg-1 at 160 W kg-1) as well as long cycle life (almost 100% capacity retention after 1000 cycles and 94% retention after 8000 cycles). The electrochemical performance of the nickel phosphate lamination structure not only is commensurate with the nanostructure or ultrathin materials carefully designed in supercapacitors but also has a longer cycling lifespan than them. The encouraging results show the great potential of this material for energy storage device applications.
Testing validity of the EKC hypothesis in South Korea: role of renewable energy and trade openness

This paper investigates the dynamic short-term and long-term relationships among per capita GDP, per capita energy consumption, per capita renewable energy consumption, trade openness, and per capita carbon dioxide (CO2) emissions within the framework of the environmental Kuznets curve (EKC) hypothesis for Korea from 1971 to 2017. According to the empirical findings of the autoregressive distributed lag (ARDL) bounds testing procedure, although increases in per capita GDP and per capita energy consumption increase per capita CO2 emissions, per capita renewable energy consumption and trade openness decrease per capita CO2 emissions. Furthermore, according to the empirical results, an N-shaped relationship has been identified between per capita CO2 emissions and per capita GDP. This indicates that our empirical findings do not support the EKC hypothesis in Korea. Thus, economic growth alone is not sufficient to address environmental pollution; in response, active environmentally friendly policies should be implemented, and the energy matrix should be transformed in favor of renewable energy in Korea.
Large scale tropical deforestation drives extreme warming

Accelerating deforestation rates in Earth's tropical rainforests have dramatic impacts on local public health, agricultural productivity, and global climate change. We used satellite observations to quantify the local temperature changes in deforested patches of rainforests across the tropics and found local warming larger than that predicted from more than a century of climate change under a worst-case emissions scenario. We show that the most extreme warming is typically found in large patches of deforestation; the combined effects of deforestation and climate change on tropical temperatures present a uniquely difficult challenge to the long term public health, occupational safety, and economic security of tropical populations.
Heterogeneous dependence between crude oil price volatility and China's agriculture commodity futures: Evidence from quantile-on-quantile regression

This paper investigates volatility dependence between global crude oil and China's agriculture futures by employing a quantile-on-quantile approach. The time-varying parameter stochastic volatility in mean model is used to evaluate the conditional volatility. The empirical results demonstrate the heterogeneous dependence between crude oil volatility and volatility in China's agricultural futures across quantiles. The absolute volatility spillover exhibits an overall increasing trend with higher quantiles of agricultural volatility, and the volatility dependence is asymmetric across violent/stable market situations. Moreover, extremely high or low quantiles of oil volatility exert a considerable influence, while crude oil volatility does not influence the agricultural volatility in the normal mode of the crude oil market. Furthermore, a high persistence is noted in the volatility dynamics, and the impacts of volatility on the returns exhibit substantial time variation. These findings could have important economic implications for portfolio managers and policymakers in different economic and financial circumstances. (C) 2020 Elsevier Ltd. All rights reserved.
How to achieve a win-win situation between economic growth and carbon emission reduction: empirical evidence from the perspective of industrial structure upgrading

Over the past 40 years since China's reform and opening up, the industrial structure has undergone tremendous changes. The rapid development of the economy has been accompanied by a surge in carbon emissions. How to achieve a win-win situation for economic growth and carbon emissions reduction has aroused widespread concern from all sectors of society. Here, this paper discusses the dynamic relationship of industrial structure upgrading, economic growth, and carbon emission reduction. Results show that there is a long-term equilibrium relationship among industrial structure upgrading, economic growth, and carbon emissions. In the short term, when the three variables deviate from the long-term equilibrium state, the non-equilibrium state will be pulled back to equilibrium with the adjustment strength of - 0.0633, - 0.0097, and 0.0013. Carbon emission reduction promotes industrial structure upgrading. Industrial structure upgrading has a greater positive impact on economic growth. Industrial structure upgrading and economic growth have a negative impact on carbon emissions, thereby promoting emission reduction. And at the 10% significance level, there is a one-way Granger causality from carbon emissions to industrial structure upgrading, economic growth can cause one-way changes in carbon emissions, and industrial structure upgrading is a one-way Granger cause of economic growth. Finally, several carbon emission reduction policies are proposed promote industrial restructuring and sustainable economic development.
Study the Effect of P. minor Seaweed Crude Extract as a Biostimulant on Soybean

&lt;b&gt;Background and Objective:&lt;/b&gt; Seaweed biostimulants are often used in agriculture because of their benefits in increasing growth, production and quality of plants and are safe for the environment. &lt;i&gt;Padina minor&lt;/i&gt; is one of the potential seaweeds that contains high macro and micronutrients and has also been shown to increase the vegetative growth of several plants. This study aims to determine the effect of &lt;i&gt;P. minor&lt;/i&gt; seaweed extract in various concentrations and frequencies as a biostimulant on the growth and production of soybean plants. &lt;b&gt;Materials and Methods:&lt;/b&gt; &lt;i&gt;Padina minor&lt;/i&gt; extract was applied to soybean plants with several concentrations (0, 10, 20, 30 and 40%) at three different application times. Where 1 application (2 weeks after planting), 2 applications (2 and 4 weeks after planting) and 3 applications (2, 4 and 5 weeks after planting). &lt;b&gt;Results:&lt;/b&gt; &lt;i&gt;Padina minor&lt;/i&gt; extract with a concentration of 40% with 1 application was able to increase plant height and shorten soybean harvest life. While the &lt;i&gt;P. minor&lt;/i&gt; extract with a concentration of 40% with two and three applications was able to increase the gross and dry weight of plants, the number of pods, gross and dry mass of whole seeds. &lt;b&gt;Conclusion:&lt;/b&gt; &lt;i&gt;Padina minor&lt;/i&gt; seaweed extract with a concentration of 40% was able to increase the growth and production of soybean plants.
Interface Defect Detection and Identification of Triboelectric Nanogenerators via Voltage Waveforms and Artificial Neural Network

To provide a robust working environment for TENGs, most TENGs are designed as sealed structures that isolate TENGs from the external environment, and thus their operating conditions cannot be directly monitored. Here, for the first time, we propose an artificial neural network for interface defect detection and identification of triboelectric nanogenerators via training voltage waveforms. First, interface defects of TENGs are classified and their causes are discussed in detail. Then we build a lightweight artificial neural network model which shows high sensitivity to voltage waveforms and low time complexity. The model takes 2.1 s for training one epoch, and the recognition rate of defect detection is 98.9% after 100 epochs. Meanwhile, the model successfully demonstrates the learning ability for low-resolution samples (100 × 75 pixels), which can identify six types of TENG defects, such as edge fracture, adhesion, and abnormal vibration, with a high recognition rate of 93.6%. This work provides a new strategy for the fault diagnosis and intelligent application of TENGs.
Sustainable energy transition readiness: A multicriteria assessment index

With climate change mainly originating from the extensive use of fossil fuels and having impacts on many aspects of life, changing the way energy is utilised constitutes a challenge that the world collectively must tackle. In this respect, all countries should implement a variety of measures focusing on energy efficiency and use of sustainable energy sources towards decarbonising their economies and achieving effective greenhouse gas emission reductions and sustainable development. Technological innovations, economic growth, societal compliance, and the regulatory and institutional frameworks constitute prominent factors that could promote, hinder or shape energy transitions as well as indicate the capacity of energy systems to be transformed. Therefore, investigating energy transitions and the extent to which countries are prepared to carry out such transitions requires the consideration of insights into multiple dimensions. This study outlines a multicriteria analysis framework to assess a country's sustainable energy transition readiness level, drawing from four pillars-social, political/regulatory, economic and technological-comprising a consistent set of eight evaluation criteria. The proposed decision analysis framework builds on the PROMETHEE II and AHP methods. Fourteen countries of different profile and level of progress towards sustainable development are evaluated and ranked, in an effort to highlight areas for improvement, and to support policymakers in designing appropriate pathways towards a greener economy.
The Combined Effects of Propionic Acid and a Mixture of Bacillus spp. Probiotic in a Plant Protein-Rich Diet on Growth, Digestive Enzyme Activities, Antioxidant Capacity, and Immune-Related Genes mRNA Transcript Abundance in Lates calcarifer Fry

A 7-week feeding trial was conducted to evaluate the combined effects of propionic acid (PA, 5 or 10 g/kg) and a multi-strain Bacillus spp. (Bacillus subtilis IS02 (accession no. JN856456) and B. licheniformis IBRC-M 11,319) (1.7 × 107 CFU/g) probiotic in a plant protein source (PP)-rich diet (∼70% of dietary protein derived from PP sources) on performance of Asian sea bass (Lates calcarifer) fry (initial body weight 2.97 ± 0.11 g). In this regard, six isoproteic (∼48%) diets were formulated as follows: a control (without supplementation of the additives); probiotic (only contained Bacillus spp. mixture); 5 g PA/kg diet; 10 g PA/kg diet; probiotic + 5 g PA/kg diet, and probiotic + 10 g PA/kg diet. Specific growth rate in fish fed with 10 g PA/kg (2.84 ± 0.1%) and diets contained blends of probiotic and PA (2.76 ± 0.19% in probiotic + 5 g PA, and 2.79 ± 0.04% in probiotic + 10 g PA) was better than in the control (2.45 ± 0.1%) (P < 0.05). Feed conversion ratio in fish fed with 10 g PA/kg (0.92 ± 0.12) and diets contained blends of probiotic and PA (0.94 ± 0.06 in probiotic + 5 g PA and 0.91 ± 0.02 in probiotic + 10 g PA) was better than in the control (1.24 ± 0.08) (P < 0.05). Digestive enzymes including α-amylase, total alkaline proteases, and bile salt dependent lipase activities improved in fish fed diets contained additives. The activity of glutathione-S-transferase and glutathione reductase enhanced in the liver of fish fed diets contained additives. The relative abundance of lysozyme, interleukin 1β, and insulin-like growth factor-1 genes mRNA transcript showed multifold increase in the liver of fish fed with the 10 g PA/kg and diets contained blends of probiotic and PA (P < 0.05). By considering the above mentioned results, supplementing a PP-rich diet with 10 g PA/kg diet or combination of PA and a mixture of Bacillus spp. probiotic recommended for L. calcarifer.
Type III cutaneous atypical meningioma of the scalp

Meningiomas occur rarely in extracranial sites, including the skin, where they may pose a diagnostic challenge because of their histopathologic overlap with several other spindle-cell tumors. Cutaneous meningiomas are divided into type I (congenital), type II (ectopic), and type III (via direct extension) lesions. We present a rare case of atypical meningioma of the skin in a 71-year-old woman who presented with a painful and enlarging lesion on the left central frontal scalp. Biopsy showed bone and soft tissue with involvement of a spindle cell neoplasm, consisting of whorled nests with atypical features, including variably increased mitotic index, areas of hypercellularity, and sheeted architecture. The overall findings were consistent with an atypical meningioma (World Health Organization grade 2). Atypical meningiomas constitute only 5% to 15% of all meningiomas. Magnetic resonance imaging of the skull later demonstrated a left frontal tumor consistent with an atypical meningioma that had eroded through the skull. Dermatopathologists should consider cutaneous meningioma as a differential diagnosis of spindle-cell neoplasms of the skin and subcutaneous tissue in head and neck.
