Transcriptome profiling of morphogenetic differences between contour and flight feathers in duck

1. This study examined the transcriptomic profiles of contour and flight feather follicles from two duck breeds to determine the molecular network and the candidate genes associated with contour and flight feather morphogenesis.2. High-throughput RNA sequencing was performed to compare differences in feather follicles between contour and flight feathers in two duck breeds (Heiwu and Nonghua duck).3. Comparing the contour feather follicles with flight feather follicles, 4,757 and 4,820 differentially expressed genes (DEGs) were identified in Heiwu and Nonghua duck respectively. Weighted gene co-expression network analysis (WGCNA) was used to construct a gene co-expression network of all DEGs and identify the key modules and hub genes associated with feather morphogenesis.4. Two key modules were enriched in many pathways involved in feather morphogenesis, such as the Wnt signalling pathway, anatomical structure morphogenesis, and focal adhesion. The CCNA2, TTK, NUF2, ECT2 and INCENP (in one module), and PRSS23, LAMC1, IGFBP3, SHISA5, and APLP2 (in another module) may be essential candidate genes for influencing feather morphology. Moreover, seven transcription factors (TFs) (UBP1, MBD2, ZNF512B, SMAD1, CAPN15, JDP2, KLF10, and MEF2A) were predicted to regulate the essential genes that contribute to feather morphogenesis.5. This work demonstrated gene expression changes of contour and flight feather follicles and is beneficial for further understanding of the complex structure of feathers.
Investigating the nexus between hydroelectricity energy, renewable energy, nonrenewable energy consumption on output: evidence from E7 countries

The transition of most economies especially heavily industrialized nations like China, Turkey, Russia, India, Indonesia, Brazil, and Mexico fondly known as E7 are fast emerging economies with its impact on economic growth and ecosystem. On the above highlight, the present study explores the dynamic interaction between hydroelectricity energy, renewable energy consumption, nonrenewable energy consumption on economic growth over annual time frequency data from 1990 to 2018. To this end, Kao co-integration technique is adopted in conjunction with panel ordinary least squares, dynamic ordinary least squares, and fully modified ordinary least square estimators over the identified blocs while the heterogeneous causality test of Dumitrescu and Hurlin is employed to detect the direction of causality among the variables. Empirical result shows long-run analysis reveals long-run equilibrium relationship between the examined variables. Furthermore, a one-way causality relationship is observed between economic growth and nonrenewable energy, economic growth and renewable energy, and economic growth and pollutant emission. The present study identifies a U-shaped pattern among nonrenewable energy consumption and economic growth in the long-run. These findings suggest that as economic growth increases, there is less strengthening of energy from the nonrenewable energy consumption hence, portentous deterioration in nonrenewable usage while authenticating the proficiency of nonrenewable energy consumption in the E7 countries. Further policy prescriptions are rendered in the concluding section.
Prehospital Drug Assisted Airway Management: An NAEMSP Position Statement and Resource Document

Airway management is a critical intervention for patients with airway compromise, respiratory failure, and cardiac arrest. Many EMS agencies use drug-assisted airway management (DAAM) - the administration of sedatives alone or in combination with neuromuscular blockers - to facilitate advanced airway placement in patients with airway compromise or impending respiratory failure who also have altered mental status, agitation, or intact protective airway reflexes. While DAAM provides several benefits including improving laryngoscopy and making insertion of endotracheal tubes and supraglottic airways easier, DAAM also carries important risks. NAEMSP recommends:DAAM is an appropriate tool for EMS clinicians in systems with clear guidelines, sufficient training, and close EMS physician oversight. DAAM should not be used in settings without adequate resources.EMS physicians should develop clinical guidelines informed by evidence and oversee the training and credentialing for safe and effective DAAM.DAAM programs should include best practices of airway management including patient selection, assessmenct and positioning, preoxygenation strategies including apneic oxygenation, monitoring and management of physiologic abnormalities, selection of medications, post-intubation analgesia and sedation, equipment selection, airway confirmation and monitoring, and rescue airway techniques.Post-DAAM airway placement must be confirmed and continually monitored with waveform capnography.EMS clinicians must have the necessary equipment and training to manage patients with failed DAAM, including bag mask ventilation, supraglottic airway devices and surgical airway approaches.Continuous quality improvement for DAAM must include assessment of individual and aggregate performance metrics. Where available for review, continuous physiologic recordings (vital signs, pulse oximetry, and capnography), audio and video recordings, and assessment of patient outcomes should be part of DAAM continuous quality improvement.
Probabilistic seismic fragility and loss analysis of concrete bridge piers with superelastic shape memory alloy-steel coupled reinforcing bars

Concrete bridge piers with conventional steel reinforcing bars are vulnerable to strong earthquakes by inducing significant residual deformations, which substantially weakens the seismic resilience of bridges. Superelastic shape memory alloy (SMA) bars showing superior self-centering capacities are desirable substitutes to steel reinforcements to minimize the seismically-induced residual deformations of piers. Nevertheless, high cost, difficult machining, and lack of sufficient energy dissipation are the primary restraining factors to a wide implementation of SMA reinforcements. This study proposes a novel SMA-steel coupled reinforcement for concrete bridge piers, which is intended to achieve the balance between self-centering and energy dissipation capacities. Probabilistic seismic fragility analyses are conducted on the prototype bridge with either pure steel, SMA-steel coupled, or pure SMA reinforcements to evaluate their probability of damage at different limit states. Seismic loss analyses are further performed to compare the relative cost-effectiveness of different patterns of reinforcements. The results indicate that an optimal amount ratio between SMA and steel bars can be found for the coupled reinforcements, which shows lower vulnerabilities and higher resilience under earthquakes than the other reinforcement patterns. The direct repair loss and the indirect downtime loss after earthquakes are considerably reduced when the SMA reinforcing bars are introduced. The coupled reinforcement with the optimal SMA-steel amount ratio shows the most effectiveness in mitigating the long-term economic impacts induced by seismic hazards within the lifetime of the bridge.
An Evaluation Model of Quantitative and Qualitative Fuzzy Multi-Criteria Decision-Making Approach for Hydroelectric Plant Location Selection

Over the past few decades, Vietnam has been one of the fastest growing economies in Asia, experiencing a GDP growth rate of more than 6% per year. The energy industry plays an important role in Vietnam's continuous development, so access to reliable and low-cost energy sources will be an important factor for sustainable economic growth. Achieving the goal of reducing global greenhouse gas emissions, as set out in the Paris agreement on climate change, will depend heavily on the development roadmap of emerging economies, such as Vietnam. Currently, developing hydroelectric plants is Vietnam's optimal choice in order to meet its target of renewable energy development. Hydroelectricity in Vietnam is favorable thanks to the high average annual rainfall, about 1800-2000 mm, and the dense river system, with more than 3450 systems. In addition to providing electricity, hydropower plants are also responsible for cutting and fighting floods for downstream areas in the rainy season, at the same time providing water for production and people's daily needs in the dry season. This work proposes the application of a multicriteria decision-making (MCDM) model to select the best option for the installation of river hydroelectric plants in Vietnam. The use of MCDM techniques in environmental decision-making, including selecting between various alternatives, is important when this involves complex decisions in several disciplinary fields. The most widely used of these techniques are the fuzzy analytical network process (FANP) and the technique for order of preference by similarity to ideal solution (TOPSIS). As a result, Nghe An (LOC05) is found to be the optimal solution for selecting river portions where hydroelectric plants are viable in Vietnam.
Economic analysis of microalgae biodiesel production in a small-scale facility

Industrial production and commercialization of biodiesel from microalgae have become a good alternative to conventional feedstock. Microalgae show high growth rate and carbon sequestration and can be easily cultivate in fresh and/or marine water, using non-arable soil. This study aims to analyze the technical and economic feasibility of biodiesel production from Phaeodactylum tricornutum, using an algae biomass production scaled-up scenario, considering local reality prices and available technologies. The model assumes 80,000 m(3) of microalgae cultivation, in a set of bubble column photobioreactors installed on 15.247 ha of land, reaching a total of 1,811 tons of microalgae biomass and 171,705 L of biodiesel per year. The production cost estimated for microalgae biomass is 2.01 (sic) kg(-1) and for biodiesel is 0.33 (sic) L-1. The ROI calculated for the project is 10% with a 10 years' payback time and an EBITDA of 588,139 (sic) year(-1). Despite the project's viability in the medium term, the cost of producing microalgae biodiesel remains high when compared to fossil fuels. Thus, unless greater technological maturity is achieved to make the process more economical, it will not be viable in the short term. (C) 2020 The Authors. Published by Elsevier Ltd.
Assessment of wind energy potential in the southeastern province of Iran

In recent years, electricity generation by employing wind turbines has been increased significantly due to technology advancement and environmental concern. In the present study, meteorological data have been employed to compute the Weibull distribution function as well as wind power and energy density. The wind data measured at 10-min intervals at three heights of 10, 30, and 40 m above the ground. Monthly, seasonal, and annual wind speed variations are analyzed, and the performance of the selected wind turbines is evaluated. The results show that the highest wind power potential occurs in July at Lotak and in August at Shandol. The estimated annual power and energy densities demonstrated that both investigated sites are suitable for large-scale power generation. Finally, the levelized cost of energy (LCOE) is employed to evaluate the economic feasibility of electricity generation from wind power energy. It was demonstrated that the minimum cost of energy achieved by Dongfang DF100-2500 model with LCOE of 0.0830 and 0.0786 USD/kWh in Lotak and Shandol, respectively.
Mechanisms of the Effects of Short-Term Inhalations of Xe and O2 Gas Mixture in the Rehabilitation of Post-COVID Ventilation Failure

The article presents a theoretical rationale and a clinical case of relief of post-COVID ventilation failure by inhalation of Xe and O2 gas mixture. Pneumonitis of coronavirus etiology transforms saturated phospholipids of surfactant into a solid-ordered phase, which disrupts surface tension, alveolar pneumatization, and alveolar-capillary gas exchange. Using molecular modeling (B3LYP/lanl2dz; GAUSSIAN09), we demonstrated that Xe atom due to the van der Waals dispersion interaction increases the distance between the phospholipid acyl chains providing a phase transition from the solid-ordered to liquid phase and restored the surface-active monolayer surfactant film. A clinical case confirmed that short-term inhalations of the Xe and O2 gas mixture relieved manifestations of ventilation insufficiency and increased SpO2 and pneumatization of the terminal parts of the lungs.
The connection between urbanization and carbon emissions: a panel evidence from West Africa

This study examined the nexus between urbanization and carbon emissions in West Africa. Second-generation econometric techniques that are robust to cross-sectional dependence and slope heterogeneity were used for the study. From the Pesaran-Yamagata homogeneity test, the slope coefficients were heterogeneous in nature. Also, the Breusch-Pagan LM test, the Pesaran scaled LM test, bias-corrected LM test, Pesaran CD test and the Friedman's test confirmed the studied panels to be cross-sectionally dependent. Further, the CADF and the CIPS unit root tests established the variables to be first-differenced stationary. Additionally, the Westerlund and Edgerton bootstrap cointegration test and the Pedroni residual cointegration test affirmed the series to be cointegrated in the long run. The Driscoll-Kraay standard errors regression estimator was employed to examine the long-run equilibrium relationship amid the series, and from the results, urbanization had a significantly positive influence on CO2 emissions in all the three panels. Also, economic growth had a materially positive effect on CO2 emissions, while renewable energy consumption had a substantially negative impact on CO2 emissions in all the panels. The causal connections amid the series were finally explored through the Dumitrescu-Hurlin panel causality test, and the discoveries were a bit varied across the various panels. Policy recommendations are further discussed.
Economic and efficient multi-objective operation optimization of integrated energy system considering electro-thermal demand response

Multi energy demand response is an important measure to achieve the economic and efficient operation of the integrated energy system (IES), which is of great significance to promote the sustainable development of the IES. The concept of demand response (DR) is extended to IES, and a double objective operation optimization model of IES considering integrated demand response (IDR) mechanism is proposed. Firstly, based on the electro-thermal IES, this paper proposes a demand response mechanism considering electric load and thermal load. According to the load composition (transferable load, reducible load, adjustable thermal load), the load management strategy is established. Then, based on the DR mechanism of electro-thermal IES, a multi-objective operation optimization model is established for the first time, which takes the economic benefits and comprehensive energy efficiency as the objective function. The model involves the equipment constraint in the process of energy production and energy transmission. The relationship between total operation cost and comprehensive energy efficiency of electro-thermal IES is analyzed in the part of Data, Simulation Results and Analysis. Finally, the results show that the model effectively improves the economic benefits and comprehensive energy efficiency of IES, and reduces the pollutants emissions to a certain extent.

Mangrove Rehabilitation and Restoration as Experimental Adaptive Management

Rehabilitated and restored mangrove ecosystems have important ecological, economic, and social values for coastal communities. Although a sine qua non of successful mangrove rehabilitation or restoration projects is accurate attention to local hydrology and basic biology of mangrove trees and their associated fauna, their long-term success depends on far more axes, each with their own challenges. Rehabilitation projects: are planned, designed, executed, and managed by people with diverse backgrounds and different scientific and socio-political agendas; need to be responsive to these multiple stakeholders and agents who hold different values; are often influenced by laws and treaties spanning local to international scales; and must be able to adapt and evolve both geomorphologically and socioeconomically over decades-to-centuries in the context of a rapidly changing climate. We view these challenges as opportunities for innovative approaches to rehabilitation and restoration that engage new and larger constituencies. Restored mangrove ecosystems can be deliberately designed and engineered to provide valuable ecosystem services, be adaptable to climatic changes, and to develop platforms for educating nonspecialists about both the successes and failures of restored mangrove ecosystems. When mangrove rehabilitation or restoration projects are developed as experiments, they can be used as case-studies and more general models to inform policy- and decision-makers and guide future restoration efforts. Achieving this vision will require new investment and dedication to research and adaptive management practices. These ideas are illustrated with examples from mangrove restoration and rehabilitation projects in the Indo-West Pacific and Caribbean regions, the two hotspots of mangrove biodiversity and its ongoing loss and degradation.
Life cycle energy, emissions and cost evaluation of CO2 air source heat pump system to replace traditional heating methods for residential heating in China: System configurations

Heat pump is an efficient method to substitute traditional boilers for cleaner space heating. A new configuration of CO2 heat pump system integrated with vapor injection and dedicated mechanical subcooling (VIDMS) is proposed, and compared with five configurations of CO2 heat pump system and three traditional heating methods. The life cycle model of energy consumption, pollutant emissions, and economic performance is developed. Assessment is conducted by taking seven typical cities located in different climate regions of China as scenarios. Coefficient of performance (COP) of VIDMS system is superior to other transcritical CO2 systems, and the COP is enhanced more notably in the case of severe cold or cold regions. The COP reaches up to 2.13 at the low ambient temperature of - 20 degrees C, 36.51% higher than the baseline (BASE) CO2 system. The primary energy consumption (PEC) of the other five CO2 systems and coal-fired boiler (CFB) can decrease by 4.15-18.26% and 19.27%, respectively, when VIDMS is adopted. Moreover, the PEC reduction is more prominent when used in severe cold region. Life cycle climate performance (LCCP) decreases significantly by employing VIDMS compared with other transcritical CO2 systems and traditional heating methods. CO2 emissions can be reduced by 13.81-23.20% and 16.56-34.31% in contrast to BASE and CFB, respectively. Furthermore, the gaseous (NOx and SO2) and particulate matter (PM2.5 and PM10) emissions also decrease. Life cycle cost (LCC) by using VIDMS is much lower than the other transcritical CO2 systems. The payback period is reduced from 5.58 to 3.55 years if the price of electricity and CO2 compressor are both reduced by 20%. The new proposed VIDMS is a more promising CO2 heat pump solution to replace traditional heating methods.
Post-pandemic citizenship: The next phase of global citizenship education

As globalization has grown, the concept of "global citizenship" has also evolved. The drive to expand citizenship beyond national borders spurred a nascent discipline known as global citizenship education (GCE). This article examines the continuum from globalization, to global citizenship, to a global pandemic (Covid-19)-and how the lessons from this growing age of globalism can serve as a blueprint for a new form of global citizenship following the pandemic, defined as "post-pandemic citizenship". The first part chronicles the drive toward globalization since the second half of the 20th century. The second part details the defining traits of global citizenship. The third part calls for a new form of global citizenship that should become part of GCE and be included in global-studies-related secondary-school courses and curricula in the wake of Covid-19-a so-called post-pandemic citizenship education (PPCE)-that emphasizes public health, empathy and compassion, self-sacrifice, and cooperative spirit.
The future(s) of digital agriculture and sustainable food systems: An analysis of high-level policy documents

Ecosystem services delivery is influenced by food systems and vice versa. As the application of digital technologies in agriculture continues to expand, digital technologies might affect the delivery of ecosystem services in view of the sorts of food systems in which they are embedded. The direction food systems develop towards the future, and the role digital technologies play in this development, is influenced by imaginings, hopes and visions about what these technologies mean for future food systems. In this article, we investigate what roles are being imagined for these technologies by international actors with the ability to influence the future of food systems. We analyze outward-facing policy documents as well as conference proceedings on digital agriculture produced by the World Bank, the UN Food and Agriculture Organisation (FAO), and the Organisation for Economic Cooperation and Development (OECD). Using qualitative textual analysis, we show that these organisations envision future food systems that prioritize maximizing food output through technology. We illustrate how this vision reflects a long-standing narrative about the role of technology in food systems innovation, which makes the controversial assumption that increases in food production lead to improvements in food security. Based on this finding, we suggest that evaluations of how digital agricultural technologies might affect the delivery of ecosystem services must begin by considering what visions of future food systems are take into account in science, technology development and policy making. Supporting similar research on high-level narratives surrounding agroecology and climate smart agriculture, we find that the dominant narrative in our dataset supports the status quo global, industrial agriculture and food system. This system continues to be criticized by many scholars for its environmental impacts. Based on our findings, we suggest that ecosystems service researchers could contribute substantially to the evaluation of environmental impacts of digital agriculture by analyzing the impact digital agriculture may have on the trade-offs between provisioning, regulatory, and cultural ecosystem services for several different food system futures. Such analyses can feed into processes of responsible innovation.
