Authors: Silva Larissa Amorim Damásio da , Macedo Bárbara Caroline , Freire Regina Maria Ayres de Camargo
Published: January 2023

A cardiopatia congênita é qualquer anormalidade na formação do coração de um bebê que acontece ainda na gestação, influenciando o desenvolvimento estrutural e funcional do sistema circulatório. O objetivo do presente artigo é abordar os efeitos psicológicos da situação de cardiopatia congênita em crianças/adolescentes, focando principalmente em como isso reflete em seus cuidadores (em geral, os pais). Trata-se de uma revisão narrativa focada em publicações do campo da psicologia sobre os efeitos de se ter um filho que passa por hospitalizações, cirurgias invasivas e possibilidades de morte nas relações familiares. Observou-se que as mães são, em geral, as principais afetadas e que há uma mudança na dinâmica familiar por vezes de forma permanente e disfuncional. O trabalho multidisciplinar de psicólogos e outros da rede hospitalar se mostram como os principais aliados no tratamento dessas famílias.

Construction work needs to be controlled for its performance through productivity calculations in order to achieve optimal cost and time. Marble covering work has a considerable weight. However, studies discussing the calculation of labor productivity for marble covering work are still few. This study aims to determine the value of productivity, coefficients, and productivity levels of labor (Labor Utilization Rate) in completing the installation of marble coverings using the wet method for floor coverings and the dry method for wall coverings with parallel patterns and diagonal patterns. The study used a work sampling method with a productivity rating approach. Primary data were collected by sampling the volume of marble covers of 482.400 m² and observations on labor groups consisting of craftsmen and helpers in predetermined zones. Furthermore, analysis was carried out using quantitative techniques of parametric inferential statistical type where the data was confirmed to be normally distributed using SPSS software. The results showed that the labor productivity of marble floor coverings was 9.896 m² / day with a coefficient of craftsman and helper of 0.101 each and a Labor Utilization Rate of 58%. Second, the labor productivity of parallel pattern marble wall coverings is 12.589 m²/day with a coefficient of craftsman and helper of 0.159 each and a Labor Utilization Rate of 57%. The labor productivity of diagonal pattern marble wall coverings was 1,549 m²/day with the efficiency of craftsman and helper of 0.646 and the Labor Utilization Rate of 55%, respectively. The results showed that the labor of marble cover work is quite productive because it has a productivity level above 50%.
Central Processes Underlying Fibromyalgia
Authors: Littlejohn Geoffrey , Guymer Emma
Published: January 2023

Fibromyalgia is a common chronic pain disorder characterised by a robust clinical phenotype with principal features that include widespread pain and tenderness, as well as high levels of sleep disturbance, fatigue, cognitive dysfunction, and emotional distress. Fibromyalgia symptoms occur along a spectrum ranging from mild to severe. The impact on the patient can be very high, with significant effects on personal, recreational, and work activities. The pathophysiology of fibromyalgia is complex and involves abnormal processing of pain and other sensory inputs from the periphery to the brain. In turn, central processes, which modulate this input, are the critical elements that initiate the sequence of events that lead to the clinical phenotype. The functioning of the stress response through its links to pain and other sensory neural processing is a key upstream component of the fibromyalgia cascade. Furthermore, emotional distress appears as a common everyday driver of this process. The mechanisms contributing to the clinical phenotype of fibromyalgia are driven by a top-down process. The aim of this review is to discuss the key central processes that underlie the fibromyalgia clinical phenotype and discuss how these should be the focus of both current management strategies and future research.
Disease-Modifying Antirheumatic Diets: The New Treatment Modalities for Rheumatoid Arthritis
Authors: Khanna Shweta , Sagar Jaiswal Kumar , Gupta Bhawna
Published: January 2023

Autoimmune responses need to be identified and managed promptly to avoid deleterious consequences. Autoimmune diseases, such as rheumatoid arthritis (RA), are debilitating and can lead to a compromised quality of life for patients. Autoimmune disease severity is directly related to sex (females are more prone to the diseases), as well as age, the environment, and genetic factors. Though many of these triggers cannot be avoided, disease onset and progression can be delayed, managed, and to some extent avoided altogether by dietary interventions. Certain food and dietary components have been observed to have anti-inflammatory properties and can thus be included in a patient’s diet to reduce disease symptoms. This review will assess dietary components with regard to RA, including those that are frequently observed to be different in patients with RA in comparison to healthy individuals. The authors conclude that assessment of the nutritional status of a patient, including the deficiency of vitamins or other nutrients and energy requirements, should be recorded and a dietary regimen should be designed accordingly for a better therapeutic response.
The Conundrum of Being a Minority: Choosing a Collective Identity in the Era of Neoliberal Globalism
Authors: KARADEMİR Aret
Published: January 2023

This paper argues that by portraying minority concerns primarily as cultural concerns and by discussing minority existence independently of capitalism, neoliberalism, feminism, environmentalism, globalization, and the distinction between the Right and the Left, the dominant discourse on ethno-cultural minorities, namely multiculturalism, may lead to the reduction of minority communities to cultural entities in the collective consciousness of the dominant majority. Such reductionism endangers minority existence by identifying the question of minorities with the question of culture to the point that minorities voicing their noncultural political concerns increasingly appear unintelligible, presumptuous, or even destructive to wider society. Against this background, the paper discusses why and how ethno-cultural minorities may find their collective identity in different, not necessarily ethno-cultural, political formations in the age of neoliberal globalism, such as anti-neoliberal, anti-globalist, cosmopolitan, environmentalist, anti-capitalist, feminist, radical democratic, republican, and anti-imperialist. This discussion is based on Ernesto Laclau’s and Chantal Mouffe’s understanding of hegemony and social antagonism.

Mechanics of gelatin-based hydrogels during finite strain tension, compression and shear
Authors: Yousefi-Mashouf Hamid , Bailly Lucie , Orgéas Laurent , Henrich Bernardoni Nathalie
Published: January 2023

Introduction: Among the biopolymers used to make hydrogels, gelatin is very attractive due to its biocompatibility, biodegradability and versatile physico-chemical properties. A proper and complete characterization of the mechanical behavior of these hydrogels is critical to evaluate the relevance of one formulation over another for a targeted application, and to optimise their processing route accordingly.

Methods: In this work, we manufactured neat gelatin and gelatin covalently cross-linked with glutaraldehyde at various concentrations, yielding to hydrogels with tunable mechanical properties that we characterized under finite strain, cyclic tension, compression and shear loadings.

Results and Discussion: The role of both the chemical formulation and the kinematical path on the mechanical performances of the gels is highlighted. As an opening towards biomedical applications, the properties of the gels are confronted to those of native soft tissues particularly complicated to restore, the human vocal folds. A specific cross-linked hydrogel is selected to mimic vocal-fold fibrous tissues.

Published: January 2023

Background: Tumorous bone defect reconstructions of the proximal humerus with joint sparing is a challenge. Numerous reconstruction methods have been proposed but the proximal residual humerus is commonly sacrificed because of its extremely short length. To preserve the proximal humerus and improve clinical outcomes, we designed a three-dimensional (3D) printed uncemented prosthesis with a porous structure to treat tumorous bone defects of the proximal humerus.

Methods: Our analysis included seven patients treated between March 2018 and July 2019. A 3D model was established, and related data were obtained, including the diameter of the humeral head, the resection length, and the residual length. A prosthesis was designed and fabricated based on these data. Functional and oncologic outcomes were recorded, and complications and osseointegration were evaluated.

Results: The mean age of the patients was 20.3 years, and the median follow-up period was 26 months. The lengths of the residual proximal humerus were 17.9 mm on average. All the patients had preserved humeral heads and most of the rotator cuff was intact. The average postoperative range of motion (ROM) of the affected shoulder was 83.8°; flexion was 82.5°, extension was 43.8°, and adduction was 16.3°. The average Musculoskeletal Tumor Society score (MSTS) was 94.3%. Good osseointegration was observed on the interface between the bone and prosthesis.

Conclusion: A 3D printed porous prosthesis with cone-like structures successfully achieved joint-sparing reconstruction of proximal humeral tumorous defects with satisfying functional outcomes. The preservation of the rotator cuff and humeral head plays an essential role in the function of the shoulder joint.

Published: January 2023

Modifying biodegradable poly (butylene adipate-co-terephthalate) (PBAT) plastic with inorganic fillers is critical for improving its overall performance, lowering the costs, and expanding its application scope. The chemical modification method for the inorganic filler determines the application performance of PBAT composites. In this work, gas—solid fluidization method was developed as a simple, efficient, and scalable strategy for chemically modifying CaCO3 filler. The modified CaCO3 filler was mixed with PBAT and melt extruded to prepare biodegradable PBAT/CaCO3 composites. The characterization results show that gas—solid fluidization method combines the traditional wet modification method’s excellent modification effect with the scalability of the traditional dry modification method. The effects of modification methods and amount of CaCO3 filling on the crystallinity, mechanical, and rheological properties of PBAT/CaCO3 composites were compared. The results demonstrated that PBAT/CaCO3 composites containing 30% gas—solid fluidization modified CaCO3 could still maintain excellent overall performance. As a result, this work provides a simple, efficient, and scalable method for chemically modifying inorganic fillers and preparing biodegradable composites.

Authors: Li Qiu-Lin , Tang Jing , Zhao Ling , Ruze Amanguli , Shan Xue-Feng , Gao Xiao-Ming
Published: January 2023

Leukocyte differentiation antigen 74 (CD74), also known as invariant chain, is a molecular chaperone of major histocompatibility complex class II (MHC II) molecules involved in antigen presentation. CD74 has recently been shown to be a receptor for the macrophage migration inhibitory factor family proteins (MIF/MIF2). Many studies have revealed that CD74 plays an important role in cardiovascular disease. In this review, we summarize the structure and main functions of CD74 and then focus on the recent research progress on the role of CD74 in cardiovascular diseases. In addition, we also discuss potential treatment strategies that target CD74. Our systematic review of the role of CD74 in cardiovascular disease will fill some knowledge gaps in the field.
Role of Connexin 43 phosphorylation on Serine-368 by PKC in cardiac function and disease
Authors: Pun Renju , Kim Michael H. , North Brian J.
Published: January 2023

Intercellular communication mediated by gap junction channels and hemichannels composed of Connexin 43 (Cx43) is vital for the propagation of electrical impulses through cardiomyocytes. The carboxyl terminal tail of Cx43 undergoes various post-translational modifications including phosphorylation of its Serine-368 (S368) residue. Protein Kinase C isozymes directly phosphorylate S368 to alter Cx43 function and stability through inducing conformational changes affecting channel permeability or promoting internalization and degradation to reduce intercellular communication between cardiomyocytes. Recent studies have implicated this PKC/Cx43-pS368 circuit in several cardiac-associated diseases. In this review, we describe the molecular and cellular basis of PKC-mediated Cx43 phosphorylation and discuss the implications of Cx43 S368 phosphorylation in the context of various cardiac diseases, such as cardiomyopathy, as well as the therapeutic potential of targeting this pathway.
Petrology and geochemical characteristics of amphibolite facies rocks in Xunyangba area, South Qinling Orogen, Central China
Authors: Kong Juanjuan , Wang Lei , Yao Yongxiang , Lin Jinyan , Xiao Yuanyuan , Yang Yiting
Published: January 2023

As a tectonic block of the Qinling Orogenic Belt, Central China, the South Qinling Orogen is generally believed to have had a tight affinity with the Yangtze Block during the Precambrian. Knowledge on the South Qinling Orogen is important to constrain the tectonic evolution of the northern margin of the Yangtze Block basement. Previous studies mainly focused on the east segment of the South Qinling Orogen. This paper presented petrological, geochronological, and geochemical studies on the amphibolite-facies rocks newly discovered in the middle section of the South Qinling Orogen. Geochemical studies indicate that the protolith of these amphibolites is calc-alkaline island arc basalt, which was formed during the reconstruction of the Paleo-Middle Archean crust on the northern margin of the Yangtze Block 2,362 ± 100 Ma ago (equivalent to metamorphic rocks of the Yudongzi group). Later, these arc basalts experienced amphibolite-facies metamorphism at 1,500–1,800 Ma, which is consistent with the metamorphism identified in the Yangtze Block, confirming the association of the South Qinling Orogen with the Yangtze Block basement. Subsequently, these amphibolite-facies rocks further experienced three stages of metamorphism at c. 800 Ma, 440 Ma, and 200 Ma in the context of the northward subduction of the Yangtze Block.
A comparison of East-Asia landfall tropical cyclone in recent reanalysis datasets--before and after satellite era
Authors: Lee Ruyuan , Chen Lei , Ren Guoyu
Published: January 2023

Based on different reanalysis datasets, reconstructions of East Asia landfall tropical cyclones (TCs) were compared with observations. The 20th-century reanalysis version 3 dataset (20CRv3) received the most approval in this assessment. It performed better in terms of annual frequency. The fifth generation of atmospheric reanalysis dataset (ERA5) and Japanese 55-year reanalysis dataset (JRA55) are also recommended in this study. Nevertheless, an apparent inconsistency in reconstructed TCs before and after 1980 is visible. Temporally, after the satellite era, the underestimation on TC frequency of the National Centres for Environmental Prediction and National Centre for Atmospheric Research (NCEP/NCAR) reanalysis dataset (NCAR) and 20-century reanalysis of European Center for Medium-Range Weather Forecasts (ERA20C) has been greatly improved. The downward trend of landfalling TCs is well captured by ERA5 and ERA20C. Spatially, the underestimation of TC track discrepancy is reduced in the post-satellite era. ERA5 and 20CRv3 showed relatively consistent performance compared to the former reanalysis in pre-and post-satellite time, which might be due to their better TC treatment. Despite the essential need for high resolution, this study stressed the importance of observation and assimilation development for the reanalysis TCs.

Published: January 2023

The Jurassic Da’anzhai Member in Sichuan Basin is an important target for shale oil exploration. Whole rock X-ray diffraction analysis, thin section, SEM and TOC testing, as well as major and trace element analysis are used to analyze the relationship of lithofacies and pore types with the sedimentary environment of the Da’anzhai Member in the Central Sichuan Basin. The results show the Da’anzhai Member in the Well Ren’an 1 (RA1) is divided into six types of lithofacies, based on a three-level division method of mineral composition-TOC-mineral structure— namely, massive mud-bearing shell limestone lithofacies (F), thick argillaceous shell limestone lithofacies (E), laminated clay silt shale lithofacies (D), thin shell calcareous shale lithofacies (C), laminated shell-bearing shale lithofacies (B), and thick clay shale lithofacies (A). The pore spaces include intergranular pores, intergranular dissolution pores, authigenic calcite intergranular pores, authigenic quartz intercrystalline pores, intergranular pores of clay minerals or pyrite nodules, as well as organic pores. The Da’anzhai Member was deposited in a semi-deep to shallow lake sedimentary environment, with relatively low salinity. This strata experienced moderate-to-strong chemical weathering as a result of the semi-arid, warm and humid paleoclimate environmental conditions that persisted during its deposition; low weathering and dry paleoclimate conditions occurred periodically. Paleoenvironment is an important influence on the lithofacies and pore types of the Da’anzhai Member. The persistence of arid climate conditions contributed to a decline in water depth, relatively high salinity, low organic productivity, and the deposition of carbonate rocks that characterize lithofacies E and F; mostly intercrystalline pores formed in these lithofacies in response to the prevailing arid climate conditions. Conversely, warm, and humid climate conditions increased the inflow of fresh water, terrigenous debris, and nutrients into the lacustrine basin that led to the deposition of fine-grained sedimentary rocks of lithofacies A, B, and C. These lithofacies are characterized by abundant nano pores, such as clay intercrystalline pores and organic pores.
Linking top and subsoil types, alteration and degassing processes at Rotokawa geothermal field, New Zealand

Published: January 2023

Surface geothermal expressions such as mud pools, fumaroles, mineral deposits, collapse pits, and hydrothermal eruption craters vary in scale and type over space and time. The evolution in space and time of these surficial thermal features strongly relates to alteration processes caused by hydrothermal fluids. The changes in the physical and mechanical properties of top and subsoils that can control fluid flow, degassing patterns, and occurrence of geothermal hazards remain understudied. The thermal area located south of the Rotokawa geothermal field (New Zealand) includes a variety of major natural surface thermal features and widespread sulphur deposits precipitated by acid–sulphate fluids in steam-heated zones. Decades of sulphur mining induced the formation of new thermal features. Such a setting represents an exemplary case study for investigating old and recently formed thermal features, soil characteristics, types and patterns of superposed hydrothermal alteration, and degassing processes. We combined field and laboratory methods to define groups of thermal features, soil types, and associated alteration. Their spatial distribution indicates that fluid circulation, alteration intensity, and degassing are strongly influenced by the local and regional geological and structural settings, as well as by mining activity. We found that at the water table level and within excavated areas, acidic fluids led to the deposition of mud deposits, sinters, and stromatolites around warm springs and mud pools. In the vadose, steam-heated portions, fluids generally leach and degrade the Taupo Pumice, resulting in broad unstable grounds and collapse structures, while extensive sulphur-encrusted grounds and sulphur-rich soils formed in excavated sites. In this framework, the degassing and fluid circulation within the top and subsoils are strongly affected by the dominant soil layer type, and in turn by its granulometry, texture, and alteration state. Our study of top and subsoils yields precious insights into surface expression variability, fluid–rock interaction processes, and sulphur deposition patterns within steam-heated zones. Processes at such a scale may strongly influence the migration of thermal manifestations, gas outputs, and ground subsidence within geothermal environments. From a broader perspective, our results will help assess the evolution of geothermal activity and related hazards in similar areas worldwide.
Two different types of provenances and the amalgamation of subduction complexes in the Eastern Tianshan of the Southern Altaids

Published: January 2023

The nature and final closure of the northern Tianshan Ocean have been debated in regard to the eastern Tianshan orogen, southern Altaids. The Kanguer subduction complex of the eastern Tianshan is the key to addressing these issues. In this study, we report new mapping, geochemical and geochronological results on the Kanguer subduction complex in the Haluo area. Our new results show that upper Permian (257 Ma) basaltic blocks emplaced in a sandstone matrix in the northern HL area are fragments of normal-mid-ocean-ridge-basalt (N-MORB)-type oceanic crust. The geochronological results indicate that the sandstone matrices display two different types of provenances. The first type in the northern part of the cross-section (till Sample YY12) has maximum depositional ages ranging from 316 Ma to 238 Ma. Their depositional settings varied from intraoceanic island arcs to continental Andean arcs after ca. 244 Ma, their detrital zircon age patterns vary from a single peak to multiple peaks, and their zircon εHf(t) values vary from uniquely high positive to some negative values. The second type is in the southern part of the cross-section with Samples YY12 to 21Kg05, which have the geochemical signatures of continental island arc sandstone, multiple-peak detrital zircon-age patterns, and positive to negative zircon εHf(t) values. The youngest sandstone sample has a maximum depositional age of 241 Ma. The above provenance results indicate that all mélanges and coherent units north of Sample YY12 belong to an accretionary complex of the Dananhu intraoceanic arc, and those south of Sample YY12 belong to an accretionary complex of the Yamansu-central Tianshan arc. According to the youngest components in both accretionary complexes, which suggest the latest subduction events, we conclude that the final amalgamation timing was after 238 Ma and that the Paleo-Asian Ocean closed during the Middle to Late Triassic.
Fission-track thermochronological evidence for the Yanshanian tectonic evolution of the northern Junggar Basin, northwest China
Authors: Li Zhenhua , Chen Zhanjun , Fan Yuhai , Yu Lan , Zhang Suya , Li Xiangyang
Published: January 2023

The Junggar Basin is a multicycle intracontinental sedimentary basin developed on the pre-Mesozoic deformed basement. For a long time, the Junggar Basin and its adjacent Altai orogeny have been a focus of debate for geologists studying the opening and closing history of the Paleozoic Asian Ocean and Cenozoic intracontinental deformation. However, there has been no detailed research on the intracontinental tectonic activities of northern Xinjiang since the Mesozoic, particularly the Yanshanian tectonic activities in the northern Junggar Basin. Fission-track (FT) dating was conducted on 15 apatite samples and eight zircon samples obtained from the northern Junggar Basin to better understand the Yanshanian tectonic evolution. The results showed that apatite FT (AFT) ages ranged from 131 to 42 Ma and zircon FT ages ranged from 205 to 132 Ma. Based on the AFT track thermal history modeling and the regional geological data, we proposed that the northern Junggar Basin underwent three tectonic thermal events during 165–161, 93–81, and 72–66 Ma. The thermal events of 165–161 Ma may indicate magmatic activity during the Yanshanian, while the 93–86 and 72–66 Ma events reflect Late Cretaceous uplift and cooling. This study has confirmed the tectonic evolution of the Yanshanian in the northern Junggar Basin from the perspective of thermochronology. It has also revealed that the Yanshanian orogeny, a regional tectonic event, may have also occurred in northwest China.
STEM learning, science identity and immersivity: Giant screen films comparing 2D, 3D, and dome formats including a videogame assessment
Authors: Johnson-Glenberg Mina C. , Kosa Mehmet , O'Rourke Holly Patricia
Published: January 2023

Multiple assessments, including a novel videogame methodology, were used to understand how viewing a Giant Screen film in four different formats affected both science identity associated with liking science and desire to be a scientist, and learning gains on STEM content. Participants were 406 5th graders who were randomly assigned to watch the 45-min film called Amazon Adventure in either a (1) 2D Small Screen, (2) 2D Giant Flat Screen, (3) 3D Giant Flat Screen, or (4) curved Dome condition. The conditions increased in levels of immersivity as listed. In this 4 × 3 design, the first factor was viewing condition and the second was test time including pretests, posttests, and two-month followup on content knowledge tests relating to natural selection. The strongest pattern was seen at the followup time point where the three more immersive conditions (2D Giant Screen, 3D Giant Screen, and Dome) outperformed the Small Screen condition on the science identity measures of liking science and wanting to be a scientist when grown up. Additionally, two of the more immersive conditions performed significantly better at both posttest and followup on the videogame that assessed natural selection and mimicry knowledge. Significant gender effects at followup revealed that females in the two most immersive conditions (3D Flat and Dome) liked science significantly more and wanted to be a scientist more than males when grown. Interestingly, females also played the videogame significantly better than the males at both posttest and followup. These results suggest that increases in the immersivity of a film can have longer term effects on science identity, and those effects are stronger in females. Additionally, as more assessments are being designed in a gamified manner, designers/researchers should keep game-style (i.e., strategy games) and gender interactions in mind. It had not been predicted that the females would outperform the males on the STEM assessment videogame, but deduction games like the one in this study are probably capturing more than knowledge about natural selection, they may be a proxies for general intelligence or g. More research is needed on game type and gender effects during the school-age developmental span.
Is prolactin receptor signaling a target in dopamine-resistant prolactinomas?
Authors: Ferraris Jimena
Published: January 2023

The hypothalamic neuroendocrine catecholamine dopamine regulates the lactotroph function, including prolactin (PRL) secretion, proliferation, and apoptosis. The treatment of PRL-secreting tumors, formerly known as prolactinomas, has relied mainly on this physiological characteristic, making dopamine agonists the first therapeutic alternative. Nevertheless, the group of patients that do not respond to this treatment has few therapeutical options. Prolactin is another physiological regulator of lactotroph function, acting as an autocrine/paracrine factor that controls PRL secretion and cellular turnover, inducing apoptosis and decreasing proliferation. Furthermore, the signaling pathways related to these effects, mainly JAK/STAT and PI3K/Akt, and MAPK, have been extensively studied in prolactinomas and other tumors as therapeutic targets. In the present work, the relationship between PRL pathophysiology and prolactinoma development is explored, aiming to comprehend the value of PRL and PRLR-associated pathways as exploratory fields alternative to dopamine-related approaches, which are worth physiological characteristics that might be impaired and can be potentially restored or upregulated to provide more options to the patients.
Improved unscented Kalman filter based interval dynamic state estimation of active distribution network considering uncertainty of photovoltaic and load
Authors: Wu Jiawei , Lin Keman , Wu Feng , Wang Zizhao , Shi Linjun , Li Yang
Published: January 2023

State estimation of active distribution network (ADN) plays an important role in distribution energy management system. The increase penetration of distributed generations, especially the distributed photovoltaic (PV), in ADN leads to high uncertainty of ADN’s operation and the state of the ADN varies with the variation of the PV output power. For the uncertainty of PV power output, an interval dynamic state estimation (IDSE) method, which estimates the interval of ADN state variables is proposed in this paper. Firstly, considering the slow computation speed of the Unscented Kalman Filter (UKF), the square root UKF is used to predict the real-time operating level of the state variables. Secondly, since the power output of PV has features of the variation randomly, the neural network-based prediction intervals is employed to predict the power output interval of PV. Finally, the normal fluctuation range of ADN state is modelled as a bilevel non-linear programming problem to perform IDSE, which in turn monitors the operating state of ADN. The proposed method is evaluated on the IEEE 33-node and IEEE 123-node systems, respectively. The test results demonstrate that the dynamic status of the ADN can be tracked accurately using the proposed method.

Authors: Zhou Hai , Li Biao , Zong Xingchen , Chen Dawei
Published: January 2023

Transactive energy systems (TESs) combine both economical and control mechanisms, and have become promising solutions to integrate distributed energy resources (DERs) in modern power systems. This article will introduce the basic concept of a TES, including its definition, process, time scale, and benefits. The configuration of the TES is then described in detail from the perspectives of the physical system, information system, transaction system, and regulatory system. The transaction mechanism allows participants (e.g., customer, generator, transmission operator, marketer, etc.) to conduct various transactions with any other party to the extent that regulatory policy permits. Transactive control is regarded as one of the most advanced approaches to realize the full response potential of flexible devices and respect the end user’s privacy, preference, and free will. Finally, some challenges to the development of TESs that arise from the limitations of current equipment level and methodological concepts will be discussed. In summary, TESs provide a more efficient, fair, and transparent environment for participants to promote DERs utilization, improve market efficiency, and increase economic benefits.

With the 2015 Paris Agreement pursuing efforts to limit global temperature increase to below 2°C above pre-industrial levels and the “energy trilemma” goals of energy security, energy equity and environmental sustainability, decarbonisation remains a priority across all of the United Kingdom (United Kingdom) energy system, not just electricity. Electricity and thermal energy storage technologies can offer a host of benefits across the energy value chain through the abilityS to capture, store and then release electricity or thermal energy over a period of time. These benefits include helping capture the full potential of renewable generation and providing services such as frequency response and reserve to Great Britain’s (GB) electricity system. In addition, with the aforementioned climate targets in mind, energy storage can also play a role in facilitating the decarbonisation of other activities and sectors. Here we delve deeper into how energy storage technologies can contribute to both energy sector transformation and more broadly, decarbonisation. Furthermore, we discuss the importance of ensuring a technology-agnostic approach to the development of policy and regulation with relevance to energy storage. This ensures that storage technologies with significant potential to contribute to the ‘energy trilemma’ goals are not precluded from entering the market due to unfavourable policy and regulatory frameworks.

The rapid development of electric vehicles (EVs) such as Easy Bike, Auto-Rickshaw, and Electric Bike is a major contributor to global energy concerns. Although electric vehicles are bringing a new dimension to the transportation sector, with advantages such as being the cheapest method of transportation and emitting fewer greenhouse gases (GHGs), the massive amounts of energy required to charge the electric vehicles is a challenging issue. Pakistan is also moving toward the use of electric vehicles however the absence of charging facilities in Pakistan slows down the charging process and increases the prices for electric vehicle users. Finding the requisite charging without threatening the current power infrastructure is one of the most challenging tasks of the present era. Renewable energy-based charging is required to fulfill the charging demand of electric vehicles. To find the best configuration to meet the necessary daily charging demand, this proposed work undertakes a techno-economic assessment for a novel renewables-based grid-tied charging station. The technical, economic and environmental impacts of Solar based grid-tied charging stations are taken into account. Moreover, the results are justified by considering the losses and building the system model. The suggested strategy decreases energy costs from $.200/kWh to $.016/kWh while reducing grid load by 254,030 kWh/yr. Furthermore, the system completes 7.7 charging sessions every day, using 13% of the electricity generated. The remaining 87% of the electricity is sold back to the grid, which generates significant revenue.

The sustainability of the ecological environment has been greatly threatened. Based on carbon emissions and combined with the panel data of 30 provinces in China from 2003 to 2020, this paper studied the various mechanisms of industrial structure optimization and population agglomeration on carbon emissions. The fixed effect model, panel threshold model and spatial spillover model are used to study the direct and indirect effects of industrial structure optimization and population agglomeration on carbon emissions, and the robustness of the results is tested in various ways. In terms of direct effects, the industrial structure optimization has a significant negative effect on carbon emissions, and the significance level is 1%. Population agglomeration has a significant positive effect on carbon emissions, with a significance level of 1%. In terms of indirect effects, 1) by adding the cross term of industrial structure optimization and population agglomeration, it is proved that population agglomeration can promote the carbon emission reduction effect of industrial structure optimization. 2) Population agglomeration was used as the threshold variable to verify the interval effect of industrial structure optimization on carbon emission reduction. The results show that the industrial structure optimization has a double threshold effect of population agglomeration on carbon emissions, and the threshold values are 2.1137 and 5.9263, respectively. And the larger the population agglomeration interval, the weaker the inhibition effect of industrial structure optimization on carbon emissions. 3) The industrial structure optimization, population agglomeration and carbon emissions have significant spatial spillover effects. The industrial structure optimization in neighboring areas has a significant inhibitory effect on carbon emissions, and the population agglomeration in neighboring areas has a significant promoting effect on carbon emissions.

Aquatic vegetation of different heights is widely scattered in natural rivers and is conducive to their environmental function while affecting the flow hydrodynamic conditions. A semi-analytical velocity model is constructed and used to study the longitudinal velocity profile in open channel flow through double-layered rigid vegetation. The double-layered vegetation flow is separated into three zones according to the velocity profile: 1) nearly uniform distributed velocity zone 1A in the lower region of the short vegetation layer, 2) a mixing layer zone B, 3) uniform distributed velocity zone 2A in the upper region of the tall vegetation layer. Two force equilibrium equations about the gravity-driving and vegetation drag are solved to obtain the uniform velocity distribution equations in zone 1A and 2A. The velocity of zone 1A and B is further modeled as a linear superposition of two concepts: the uniform velocity distribution term of zone 1A and a hyperbolic tangent profile. Meanwhile, longitudinal velocity and the lateral vorticity profiles of open channel flow through double-layered rigid vegetation are studied by laboratory flume tests of different vegetation arrangements exposed to two water depths and three slopes. The experimental results show that the longitudinal velocity increases with the slope increase. The verification of the velocity model is based on the instantaneous velocity measured by Acoustic Doppler Velocimetry (ADV), which shows acceptable agreement, indicating that the model can give a reference to the longitudinal velocity of multi-layered vegetation flow in some cases. The effects of wake vortices and boundary friction on the model are further explored in the discussions. The results presented in this study could contribute to the management of aquatic vegetation configurations and the restoration of freshwater ecology.

Based on hourly station precipitation data and ECMWF ERA5 reanalysis data from 2009 to 2019, this paper explores the temporal variations and spatial distribution of short–duration heavy rainfall (SDHR) induced by North China cold vortices (NCCV) over the Beijing-Tianjin-Hebei (BTH) region, and comparatively analyzes the characteristic of environmental parameters and then choose some predictors to make probability forecasting for short–duration heavy rainfall induced by North China cold vortices. Results show that short–duration heavy rainfall has obviously interannual, monthly and diurnal variations. Areas of high short–duration heavy rainfall frequency caused by North China cold vortices exhibit eastward movement, which generally locate along the mountain areas of the Beijing-Tianjin-Hebei region in the afternoon, and moves to the coastal areas of the Beijing-Tianjin-Hebei region after midnight. In general, short–duration heavy rainfall induced by North China cold vortices mainly occurs in 16:00–21:00 and around 02:00–05:00, showing a delayed peak time and a secondary peak time in recent years. Besides, short–duration heavy rainfall caused by North China cold vortices occurs fewer but more extremely over the northwestern and southern parts of the Beijing-Tianjin-Hebei region, more frequently and extremely over the border area of the Beijing-Tianjin-Hebei region, and more frequently but with moderate intensity over the coastal area of the Beijing-Tianjin-Hebei region. By comparing the distribution characteristics of some physical parameters for three categories of no precipitation, ordinary precipitation, and short–duration heavy rainfall weather induced by North China cold vortices, it is found that moisture and atmospheric instability conditions have great significance for the occurrence of short–duration heavy rainfall caused by North China cold vortices. Probability forecast for short–duration heavy rainfall caused by North China cold vortices is made based on ingredient method and fuzzy logic algorithms. The result shows the products have good performance, further implying the significance of the environmental parameters for forecasting short–duration heavy rainfall caused by North China cold vortices.
