ABSTRACT

The connection between Earth's global temperature and carbon dioxide (CO2) emissions is one of the highest challenges in climate change science since there is some controversy about the real impact of CO2 emissions on the increase of global temperature. This work contributes to the existing literature by analyzing the relationship between CO2 emissions and the Earth's global temperature for 61 years, providing a recent review of the emerging literature as well. Through a statistical approach based on maximum entropy, this study supports the results of other techniques that identify a positive impact of CO2 in the increase of the Earth's global temperature. Given the well-known difficulties in the measurement of global temperature and CO2 emissions with high precision, this statistical approach is particularly appealing around climate change science, as it allows the replication of the original time series with the subsequent construction of confidence intervals for the model parameters. To prevent future risks, besides the present urgent decrease of greenhouse gas emissions, it is necessary to stop using the planet and nature as if resources were infinite.

ABSTRACT

Vehicle mileage is one of the key parameters for accurately evaluating vehicle emissions and energy consumption. With the support of the national annual vehicle emission inspection networked platform in China, this study used big data methods to analyze the activity level characteristics of the light-duty passenger vehicle fleet with the highest ownership proportion. We found that the annual mileage of vehicles does not decay significantly with the increase in vehicle age, and the mileage of vehicles is relatively low in the first few years due to the run-in period, among other reasons. This study indicated that the average mileage of the private passenger car fleet is 10,300 km/yr and that of the taxi fleet was 80,000 km/yr in China in 2019, and the annual mileage dropped by 22% in 2020 due to the pandemic. Based on the vehicle mileage characteristics, the emission inventory of major pollutants from light-duty passenger vehicles in China for 2010–2020 was able to be updated, which will provide important data support for more accurate environmental and climate benefit assessments in the future.

ABSTRACT

Coal energy landscapes have changed dramatically over the last decades, including geographic shifts in production and consumption, technological changes that have reduced labour demand and led to relatively new mining practices (e.g. invasive mountain-top approaches), changed economic footprints, a shutdown of capacities or a complete end of mining in many regions with massive impacts on regional and local economies, community well-being, social capital, et cetera. Then the Covid-19 pandemic and Russia´s invasion of Ukraine have fundamentally affected the global economy, disrupted energy markets, and shattered existing estimates about development trends, challenging the progress and speed of the low-carbon energy transition and coal phase-out. This article provides a brief reflection on the changing landscapes of coal and their possible futures, and serves as an introduction to the Special Issue of Moravian Geographical Reports on "The death of coal in the energy transition? Regional perspectives”.

ABSTRACT

Background: In making investment decisions, asset risk and return are two crucial criteria on which investors base their decision.Objectives: This paper provides risk and return analysis and compares different traditional and alternative investments with special emphasis on the COVID-19 crisis. Assets included in the analysis are stocks, bonds, commodities, real estate, foreign exchange, cryptocurrencies, renewable energy sources, gold, and oil.Methods/Approach: The risk measures of standard deviation, Value at Risk (VaR), Conditional Value at Risk (CVaR), and Sharpe ratio are used to compare the representatives of each asset class.Results: The crisis had the highest impact on the risk of crude oil, renewable energy sources, real estate, and stocks, a slightly lower impact on the risk of commodities and gold, and a very low impact on the risk of bonds, foreign exchange, and cryptocurrencies. The order of assets regarding earning potential during the crisis, compared to the period before the crisis, changed significantly for commodities in a positive way and for gold and bonds in a negative way.Conclusions: This research shows that stocks won against all other assets, including gold and cryptocurrencies, during the COVID-19 crisis. The good features of a new alternative investment – renewable energy sources – with excellent earning potential are shown.

ABSTRACT

Today, the World Health Organization has declared a global health emergency, caused by the Monkeypox outbreak. In the monthly analysis for June, 3500 cases have been reported in 50 countries around the world. In the analysis for July, more than 30000 cases have been reported in 75 countries. Thus, in the circumstances of the continuing COVID-19 pandemic, the appearance and dynamics of spreading of Monkeypox is alarming. In this paper, for the first time, elemental composition of Poxvirus, Monkeypox virus, and Vaccinia virus have been reported. Additionally, thermodynamic properties have been reported for nucleic acids, nucleocapsids, and entire virus particles. The similarity in chemical composition and thermodynamic properties of the analyzed viruses has been used to explain the crossed immunity to Poxviruses. Finally, binding thermodynamic properties have been reported for the Vaccinia virus.

ABSTRACT

Brazil has experienced a notable weakening of its institutional framework related to the implementation of an agenda for sustainability since the Jair Bolsonaro Administration. Aiming to identify trends and ruptures, this paper explores four axes of current Brazilian environmental governance, taking four Sustainable Development Goals (SDGs) as an analysis tool: Gender (SDG 5), Energy (SDG 7), Solid Waste (SDG 12), and Life on Land (SDG 15). The study is structured as a critical essay, supported by the historical evolution of the indicators associated with the analyzed SDGs. It is concluded that there has been a weakening of environmental governance, within an understanding of the importance of a multi-stakeholder articulation and participatory governance. It is verified that there cracks have developed since 2019 at the federal level, with a discontinuity in a number of key policies, while at the territorial levels, there are historical trends that already showed injustices in the social and environmental scope, which have been aggravated in the face of the COVID-19 crisis.Alternate : O Brasil experimenta um notável enfraquecimento da institucionalidade relativa à implementação de uma agenda para a sustentabilidade, a partir do governo de Jair Bolsonaro.

O trabalho está estruturado como um ensaio crítico, subsidiado pela evolução histórica dos indicadores associados aos ODS analisados. Conclui-se que há um enfraquecimento da governança ambiental, dentro de um entendimento da importância de uma articulação multi-atores e de governança participativa. Verificam-se que existem fissuras a partir de 2019 no nível federal, com uma descontinuidade em várias políticas importantes, mas nos níveis territoriais existem tendências históricas que já mostravam injustiças no âmbito socioambiental, que se agravam diante da crise da COVID-19.Alternate : Brasil experimenta, a partir del gobierno de Jair Bolsonaro, un notable debilitamiento de la institucionalidad en lo relativo a la implementación de una agenda hacia la sustentabilidad.

ABSTRACT

Quinn et al discuss the treatment of common and potentially modifiable symptoms of post-COVID-19 condition (long COVID) in adults. The symptoms include fatigue and postexertional malaise, anxiety, depression and posttraumatic stress disorder, and dyspnea. To avoid precipitating postexertional malaise, patients should be advised to begin a structured and symptom-guided return to activity program, tailored to their severity of fatigue. Meanwhile, in people with mild dyspnea, pursed lip or deep breathing exercises may improve symptoms.

ABSTRACT

When the Indian government declared the first lockdown on 25 March 2020 to control the increasing number of COVID-19 cases, people were forced to stay and work from home. The aim of this study is to quantify the impact of stay-at-home orders on residential Air Conditioning (AC) energy and household electricity consumption (excluding AC energy). This was done using monitored data from 380 homes in a group of five buildings in Hyderabad, India. We gathered AC energy and household electricity consumption data at a 30-min interval for each home individually in April 2019 and April 2020. Descriptive and inferential statistical analysis was done on this data. To offset the difference in temperatures for the month of April in 2019 and 2020, only those weekdays were selected where the average temperature in 2019 was same as the average temperature in 2020. The study establishes that the average number of hours the AC was used per day in each home increased in the range 4.90–7.45% depending on the temperature for the year 2020. Correspondingly, the overall AC consumption increased in the range 3.60–4.5%, however the daytime (8:00 AM to 8:00 PM) AC energy consumption increased in the range 22–26% and nighttime (8:00 PM to 8:00 AM) AC energy consumption decreased by 5–7% in the year 2020. The study showed a rise in household electricity consumption of about 15% for the entire day in the year 2020. The household electricity consumption increased during daytime by 22- 27.50% and 1.90- 6.6% during the nighttime. It was observed that the morning household electricity peak demand shifted from 7:00 AM in 2019 to 9:00 AM in 2020. Conversely, the evening peak demand shifted from 9:00 PM in 2019 to 7:00 PM in 2020. An additional peak was observed during afternoon hours in the lockdown. © 2022, The Author(s).

ABSTRACT

AIMS: This study aimed to examine and compare the use of energy drinks, over-the-counter (OTC) painkillers and misuse of prescription drugs in two cohorts of Norwegian adolescents entering high school (i.e. grade 11) immediately prior to and during the initial year of the COVID-19 pandemic. METHODS: Accelerated longitudinal design and multi-cohort sampling enabled identification of the two socio-demographically comparable cohorts of grade 11 students: (a) COVID-19 cohort assessed in the autumn of 2020 (n=915) and (b) pre-COVID-19 cohort assessed in the autumn of 2018/19 (n=1621). Unadjusted and adjusted logistic and Poisson models were used to estimate the proportion of (mis)users and use frequencies among (mis)users in two cohorts. RESULTS: Energy drinks use was both more common in the COVID-19 cohort (60.8% vs. 52.5%;adjusted odds ratio=1.40, 95% confidence interval (CI) 1.18-1.66, p<0.001) and more frequent among users from this cohort than among their pre-COVID-19 counterparts (9.58 vs. 7.79 days past month, adjusted incidence risk ratio (aIRR)=1.23, 95% CI 1.14-1.32, p<0.001). No cohort differences were observed in OTC painkillers use. Prescription drugs misuse was equally common in the two cohorts but was more frequent among misusers from the COVID-19 cohort than among their pre-COVID-19 counterparts (18.94 vs. 12.45 times past year, aIRR=1.52, 95% CI 1.10-2.10, p<0.001). CONCLUSIONS: Norwegian adolescents from the COVID-19 cohort were more likely to use energy drinks and, once engaged in these behaviours, to use energy drinks and misuse prescription drugs more frequently than their pre-COVID-19 counterparts.

ABSTRACT

During the twentieth and twenty-first centuries, the oil industry has been pivotal in influencing all countries' geopolitical, economic, and human development strategies. Until recently, the debate was about peak oil and what would happen after oil finished. However, due to technological advances and hydraulic fracturing, shale oil formations have become economically viable due to the United States' desire to achieve energy security to make a qualitative shift in the oil industry and the geopolitics of oil. Therefore, this paper deals with an economic model that illustrates the impact of oil price fluctuations to the shale oil and gas companies by analyzing the main determinants of continuity of shale oil and gas companies in production if global oil prices decline or rise. In addition, the study will investigate the effects of OPEC+ policy and Covid-19 on the future of shale oil industry. The study will discuss some future scenarios for global energy trends and predict what the shale industry will look like in the future. The study concluded the shale industry faces an internal destructive process (within the industry itself) and external (Renewable energy, OPEC and Covid-19). The stability of oil prices is a critical factor that promotes the shale industry's recovery. However, shale industry is expected to continue with low productivity growth rates and continuing government support for it. © The Author(s) 2022.

ABSTRACT

Rapid urbanization in developing countries has come at great costs in terms of the increasing energy demand. As India is a developing nation, the rising per capita income, and increasing purchasing power of domestic alliances by households, are pushing the household energy demand to rise sharply. Thus, there is a need to move towards the implementation of Net-Zero buildings in the residential sector in India to curb the escalating trend of energy demand. Although Rooftop Solar Photovoltaic has gained attention as a sustainable energy alternative to conventional sources, the potential of façade solar PV for harnessing alternative energy sources remains unexplored. This study aims to design and assess the feasibility of a grid-connected façade solar PV to meet the energy demand of residential complexes in a residential academic campus in India. Three groups of residential complexes based on energy-related user behaviour and built area have been identified in the study. Further, the maximum energy demand recorded in CoVID-affected years has been considered for designing the PV system. The study demonstrates that Façade Solar PV can solely meet 77-82% of the maximum energy demand of each group, and meets the Net-Zero potential for the studied residential typologies. Furthermore, it has been found, that the current residential benchmarking and labeling by the Bureau of Energy Efficiency (BEE), are largely climate-based and do not correspond with housing typology and built area. Thus, this study proposes a novel energy benchmarking and labelling system, based on the studied housing typology and corresponding energy usage, expressed in terms of the Energy Performance Index (EPI). It is found that the proposed energy efficiency labels for different typologies vary from the existing BEE residential benchmarking labels in terms of the calculated EPI and corresponding star rating when considered for Warm and Humid climatic zone. © 2022 ACM.

ABSTRACT

Water heating in Pakistan and its neighboring countries predominantly relies on inefficient, natural gas-wasting water heaters whose mechanical design has remained largely unmodified since their inception in the 1960s. The inefficiency of these water heaters has added much to the woes of depleting gas reserves of the region, leading to a widening demand-supply gap. Pakistan is facing its worst ever natural gas crisis due to a COVID-19 hit economy that cannot carry the burden of expensive imports, especially during the Russo-Ukrainian conflict that has sent the gas prices soaring in the international market. We respond to this challenge with a sense of urgency by proposing a solution that minimizes the wastage of natural gas in water heating, which consumes about half the gas supplied to residential consumers in the country. Our solution replaces the mechanical control of the water heater with an IoT-inspired, electrical retrofit design combining hardware and software for smart control through user-defined schedules or machine learning, while solving several challenges that arise from replacing a mechanical control system with an electrical one. Empirical results demonstrate 70% reduction in consumption. © 2022 ACM.

ABSTRACT

Many steam turbine modernizations projects evaluated today are viewed by operators with focus to mitigate risk, minimize outage time, and maintain reliability, while getting the best cost-benefit possible. This technical paper will take you through the steps on how the owner/operator, Gainesville Regional Utilities (GRU), began evaluating traditional modernization approaches for their JR Kelly Unit 8, reevaluating alternatives from multiple suppliers, and eventually selecting a Brownfield Steam Turbine Generator Exchange (BEX) as the most technically viable and economic solution to support their current and future power plant needs. Utilizing a brownfield exchange concept, known most typically to be associated with gas turbines, this approach involved removal of the entire original steam turbine-generator unit and replacement with new latest technology steam turbine-generator components, while re-using the turbine building, condenser cooling, and electrical connections. Siemens Energy Inc. (Siemens Energy) provided this Florida utility with a comprehensive package which included demolition of the existing turbine-generator equipment, integration engineering services, supply and delivery of a new steam turbine-generator set, gear box, field installation components, technical field assistance services, field installation services, start up and commissioning services, and performance testing services. Major components were skid mounted and installed onto existing turbine deck. The project was implemented in Spring 2021 during the height of the Covid pandemic, which presented additional challenges to the stakeholders and will be discussed. Authors include GRU Project Manager, GRU Manager of Outage Planning & Major Maintenance, and Siemens Energy Steam Turbine Modernization Project Lead, who will share their critical perspectives of the project.

ABSTRACT

AIMS: The aims of the research are to investigate (1) the influence of managerial humour on nurses' coworker-directed helping behaviour, (2) the mediating effect of nurses' feelings of energy between managerial humour and nurses' coworker-directed helping behaviour and (3) the moderating effect of nurses' power distance orientation. DESIGN: This is a quantitative study. A three-wave survey design was conducted to collect data from direct managers to nurse dyads. METHODS: The random sampling method was employed. Data were collected from the supervisor to subordinate dyad at three time points during the first half of 2021. A total of 235 paired data sets of nurses and their direct managers were collected from a large state-owned Chinese hospital. We used hierarchical regression analyses via SPSS 22.0 software to examine the hypotheses. RESULTS: (1) Managerial humour can foster nurses' coworker-directed helping behaviour via accumulating their feelings of energy. (2) Power distance orientation moderates the effect of managerial humour on feelings of energy as well as the indirect effect of managerial humour on nurses' coworker-directed helping behaviour via feelings of energy, in a way that these effects are stronger when nurses have higher (vs. lower) level of power distance orientation. CONCLUSION: Managerial humour can increase nurses' feelings of energy, which in turn, motivates them to help their coworkers. Nurses' power distance orientation is an important boundary condition that constrains managerial humour effectiveness. IMPACT: Hospital managers could use more humour during their interactions with nurses because managerial humour can promote nurses' feelings of energy and coworker-directed helping behaviour. Hospitals can take humour into account during managers' selection and training to improve management effectiveness. Managers in eastern countries should use more humour during their interactions with followers. PATIENT OR PUBLIC CONTRIBUTION: Nurses and their direct managers from a large state-owned Chinese hospital contributed to this study by completing the survey.

ABSTRACT

The outbreak of COVID-19 has greatly changed everyone's lifestyle all over the world. One of the best ways to prevent the spread of infections is by washing hands properly. Although a number of hand hygiene monitoring systems have been proposed, they either cannot achieve high accuracy in practice or work only in limited environments such as hospitals. Therefore, a ubiquitous, energy-efficient and highly accurate hand hygiene monitoring system is still lacking. In this paper, we present WashRing—the first smart ring-based handwashing monitoring system. In WashRing, we design a Partially Observable Markov Decision Process (POMDP) based adaptive sampling approach to achieve high energy efficiency. Then, we design an automatic feature extraction scheme based on wavelet scattering and a CNN-LSTM neural network to achieve fine-grained gesture recognition. Finally, we model the handwashing gesture classification as a few-shot learning problem to mitigate the burden of collecting extensive data from five fingers. We collect data from 25 subjects over 2 months and evaluate the system performance on both commercial OURA ring and customized ring. Evaluation results show that WashRing achieves 97.8%accuracy which is 10.2%–15.9%higher than state-of-the-arts. Our adaptive sampling approach reduces energy consumption by 64.2%compared to fixed duty cycle sampling strategies. IEEE

ABSTRACT

Molecular docking plays a vital role in modern drug discovery, by supporting predictions of the binding modes and affinities of ligands at the binding site of target proteins. Several docking programs have been developed for both commercial and academic applications. Typically, a docking program’s performance depends on the sampling algorithm used to generate the ligand’s potential conformations and the scoring function applied to evaluate and rank these conformations. Evolutionary algorithms are widely used as sampling algorithms in docking programs. However, both the linkage problem and the dimensionality degenerate the search ability of evolutionary algorithms in the docking process. Therefore, a newly designed docking program named AutoDock Koto was developed in this study, which adopts a novel gradient boosting differential evolution algorithm to effectively address these issues. Experimental results show that compared with commonly used docking programs, AutoDock Koto yields dramatic improvements in docking performance based on an extensive dataset of 285 protein-ligand complexes. In addition, due to its strong docking ability, AutoDock Koto was used to identify potential drugs for COVID-19 based on a virtual screening of all approved drugs in our experiments. Sixteen drugs are found to possess low binding energy to the main target protease of SARS-CoV-2, and thus have the potential to treat COVID-19 as antiviral drugs.

ABSTRACT

The COVID-19 pandemic had a tremendous impact on socioeconomics and directly impacted the electrical system. In Malaysia, Grid System Operators (GSOs) were found to lack detailed information to differentiate the total energy demand before and during a pandemic. Working from home during the pandemic has changed the way of life and daily energy management methods for the domestic sector. This paper aims to study the national energy demand during the pandemic and then look into domestic energy management. The study included 3 phases. Phase 1 involved the analysis of data from the GSO to identify differences in energy demand before and during the pandemic. Next, in phase 2, a survey will be conducted on the energy management of the domestic sector. Finally, phase 3 involves household energy-saving proposals through examples of structural improvements. During the 2020 Movement Control Order (MCO) in Malaysia, the average total decrease in energy demand compared to 2019 was 15.82%. This high percentage is due to the closure of several economic sectors, such as trade and industry. From the survey, 88 110 respondents reported that domestic electricity bills increased during the MCO. Statistical analysis using ANOVA indicated no significant link between age range and behavior, knowledge, and total bills paid by respondents. Furthermore, this study also suggested structural upgrades incorporating 5-star air conditioning that can save RM389.47 per year, which will take 4.78 years to repay. This study concluded with suggestions on changes that can be implemented to aid homeowners with energy savings. © 2022 IEEE.

ABSTRACT

The pandemic caused by the coronavirus SARS-COVID-2 has had devastating impact on the world. It has caused a significant number of deaths across the world. Fast spread and lack of vaccine prompted academia to adopt new, fast and reliable methodologies to design new drugs. A combined approach of direct drug design and indirect drug design has been used for molecular docking. In the study, we found a compound, Vilazodone, with a binding energy of -8.40 kcal/mol. The druglikeness properties of this compound are investigated through SWISS ADMET analysis. In this in-silico study, we confirmed this compound is a potential drug candidate against SARS-CoV-2.However, in-vitro and in-vivo studies are required to prove its efficacy. © 2022 IEEE.

ABSTRACT

Digital Contact tracing with smartphone apps may help control the spread of serious pathogens, such as COVID-19. Such apps typically use peer-to-peer Bluetooth data transfer to record a contact. However, they suffer from low adoption rates, high false alarm contact indications, battery drain, and user privacy concerns. This paper proposes BECT or BEacon-based Contact Tracing, a contact tracing framework using static Bluetooth beacon devices installed in public or private places that periodically broadcast packets to nearby users that are stored as coins. Users that are positively diagnosed submit their coin IDs to a third-party service (e.g., local health authority) which can mark these coins as infected and disseminate them to other users. A match between a user's stored coins and an infected coin implies that the user has come in direct or indirect contact with an infected person. The BECT framework does not expose users' private data and conserves the device battery. We use MATLAB simulations to compare the performance of the BECT framework to phone-phone apps in a restaurant scenario and show that BECT has superior contact tracing performance. We also provide general deployment guidelines. © 2022 IEEE.
