Authors: Sun Ke , Lin Huixi , Wang Guanmin , Chen Qinghua , Zhang Jibiao
Published: May 2022

Upper Carboniferous-Middle Permian platform margin reef-shoal reservoirs are one of the most important exploration targets for the northwestern margin of Tarim Basin. In order to obtain a clear understanding of the controlling factors for the platform margin reef-shoal development, field outcrops in the Wushi area, northwestern margin of Tarim Basin had been studied in this article by field measurements, thin section identification, carbon and oxygen isotope testing, and ancient provenance analysis. Studies have shown that the platform margin reefs in the Wushi area were dominated by algae reefs, and the platform margin shoals are dominated by bioclastic shoals and gravel shoals. The characteristics of algal bind inside grains were common. During the Zhaerjiake period, interbedded reefs and shoals were the main type, and platform marginal reefs were of the progressive type. During the Balediertage period, huge thick platform margin reefs were the main type, and the platform margin reefs were of accretion-weak progressive type. The development controlling factors of the platform margin reef-shoal are mainly relative sea-level change, palaeosource, and paleogeomorphy. Relative sea-level changes controlled the development characteristics and superposition mode of the platform margin reef-shoal; there were two sides of the influence of the palaeosource on the platform margin reef-shoal; the paleogeomorphology controlled the development position and spreading scale of platform margin reef-shoal. In the covering area, the platform margin reef-shoal reservoirs adjacent to the fault zone and with large sedimentary thickness might have a good prospect for hydrocarbon exploration.

Published: May 2022

To solve the difficult problems of large‐scale utilization of solid waste soda residue (SR) as a resource and reduce the cost of road building materials, the technical idea of using SR instead of part of lime to prepare lime soil of pavement base was put forward. Through laboratory tests, the basic characteristics of SR and the optimum moisture content and maximum dry density of soda residue lime soil (SRLS) under different proportioning conditions were tested. The test results showed that (1) with the change of SR content in the range of 0%–12%, the optimum moisture content of SRLS showed the change law of first increasing and then decreasing, but the change range was small; (2) the UCS of SRLS gradually increased with the extension of curing age, with the strength increasing faster in the early stage and slower in the later stage. The UCS of SRLS with SR content in the range of 0%–12% shows the law of first increasing and then decreasing, and the UCS value was the highest when the content of SR is 3%. Compared to the control group, the increase in the amplitude of UCS is as high as 34.6%; (3) appropriate content of SR will increase the gelation of C‐S‐H and N‐A‐S‐H, and at the same time generated hydrated calcium sulfate and other cementitious materials, enhancing the cementation and strength of SRLS. However, when the content of SR is too much, the excess SR will not participate in hydration reaction even reduce the strength of lime soil. The cost of road materials per kilometer in the test section of SRLS base can be saved by 164,000 yuan, and the treatment cost per ton of SR in alkali factory can be reduced by about 80 yuan. The research results have remarkable economic, technical, and social benefits, which can provide technical reference for large‐scale recycling of solid waste SR.

Authors: Ren Yiran , Cheng Jian , Chen Jie
Published: May 2022

In order to solve the error prevention problem of secondary equipment in intelligent substations, this paper designs the Substation Secondary Equipment- (SSE-) oriented error risk Prevention, Control, and Management (P&C&M) system. Firstly, the basic principle of SSE error prevention is reviewed. The SSE model is expanded based on the existing microcomputer error prevention system’s Substation Primary Equipment (SPE). Thereupon, the SSE status acquisition device is designed, and the overall architecture is implemented for SSE error prevention. Secondly, edge-node cooperation is analyzed along with the specific architecture of the edge gateway. Finally, the wireless communication network is designed based on the edge gateway. The delay and flow of different data streams are compared, and the error proof verification mechanism is introduced into SSE. The numerical results corroborate that when the Sampled Value (SV) traffic exceeds 32 Mbps, the maximum delay exceeds the specified delay (3 MS). The average flow of the Manufacturing Message Specification (MMS) message is 90 kbps, which can meet the requirements of the intelligent substation. The delay of star networking is higher than that of ring networking. Meanwhile, the proposed network analyzer has a measured flow closer to the calculated flow of SSE. In the 60-hour accuracy statistics, the proposed SSE-oriented error P&C&M system reaches an accuracy as high as 84%. Therefore, the proposed SSE-oriented error P&C&M has strong feasibility. The outcome provides a reference for the intelligent development of error prevention of secondary equipment in intelligent substations.

Authors: Zhang Lili
Published: May 2022

In order to promote the orderly development of cities and realize social public interests, a design method of a land reserve-oriented multimedia information management system is proposed. It is of great practical significance to integrate and sort out the whole process of land reserve projects through spatial information platform, effectively manage land reserve, land supply, and planning information, improve the utilization rate of land resources, and provide information support and decision-making basis for land expropriation and land registration and certification. By combining scattered information resources, integrated into a unified information service platform, realize the unified update and maintenance of all kinds of data, increase the reusability of data, and avoid data synchronization between the two levels of urban land reserve departments and the resulting waste of resources. After three tests and modifications on 50 devices, successfully increased the operation success rate from 86% to 100%, and a complete and effective land reserve multimedia information management system has been successfully developed. In order to better do the handover and transition of the reserve work, it is necessary to integrate, update, and improve the historical and existing reserve projects and build a unified and standardized land reserve geographic information database, so as to effectively promote the sharing and application of information resources.

Published: May 2022

Aiming at the local freight train transit system in railway terminal, the optimization of simultaneous delivery and pickup wagon scheme on hybrid siding network is presented. The problem is formulated as a mathematical programming model. The objective function intends to minimize shunting engines’ operating cost, wagons’ travelling cost, and penalty cost for exceeding the retrieval time window. Some constraints indicating the relationship between delivery and pickup wagons, relationship between radial branches and operation batches, relationship between local wagon groups’ retrieved time and outbound train departure time, and relationship between tasks and operation batches are considered in the model. As an NP problem, using traditional method to solve the model is difficult and inefficient. A novel two‐stage hybrid optimization procedure is proposed. Firstly, the three‐phase approach composed of coding task sequence, dividing task batch, and generating access order sequence population is developed to generate initial solution. Secondly, an asynchronous iteration heuristic is provided. The iteration object is given as the expression form of the solution representing the delivery and pickup wagon sequence and then the initial iteration population is generated. Furthermore, the primary updating iteration population with pending and remaining groups is introduced to optimize iteration object Then, the senior updating iteration population with Lévy flight searching is also introduced to optimize further iteration object. Finally, the experimental scenarios are designed to test the proposed approach. Also, the proposed approach is compared with some other approaches and the performance of the proposed approach is evaluated by some different sized instances.

Study on the Corrosion and Scale Inhibition Mechanism of the Thiourea-Modified Polyepoxysuccinic Acid (CNS-PESA)
Authors: Htet Thin Thin , Zeng Defang
Published: May 2022

In this paper, thiourea-modified polyepoxysuccinic acid (CNS-PESA) was synthesized and used as a corrosion and scale inhibitor for the circulating cooling water system of the factory. Polyepoxysuccinic acid (PESA) has been widely used in industrial water treatment due to its good corrosion inhibition and scale inhibition performance. It also acts as a reliable material for dispersion of iron oxide, good biodegradation efficiency, and phosphorus-free content. The scale inhibition performance for calcium carbonate and calcium phosphate scale with corrosion inhibition performance using different inhibitor concentrations, temperatures, pH, and calcium ion concentration on scale inhibition efficiency were studied. The scanning electron microscope (SEM) analysis on the scale and corrosion of carbon steel with two methods as GB/T 18175-2000 “Measurement of inhibitors in water treatment: rotation coupon method” and electrochemical method for CNS-PESA and PESA were utilized. Compared to using CNS-PESA and PESA for calcium carbonate and calcium phosphate, the scale inhibition rates were increased by 6% and 18.7%, and the corrosion inhibition rate increased by 22.4%. The scale inhibition efficiency of CNS-PESA is best when the calcium ion concentration is less than or equal to 350 mg/L. Moreover, the thiourea-modified polyepoxysuccinic acid (CNS-PESA) was phosphorus-free corrosion and scale inhibitor and minimizes environmental pollution problems.
A Two-eRNA-Based Signature Can Impact the Immune Status and Predict the Prognosis and Drug Sensitivity of Lung Adenocarcinoma
Authors: Wang Li , Zhou Shao-quan , Zhou Yu , Lu Jia-xi
Published: May 2022

Enhancer RNAs (eRNAs) are intergenic long noncoding RNAs (lncRNAs) participating in the development of malignant cancers via targeting cancer-associated genes and immune checkpoints. Immune infiltration of the tumor microenvironment was positively associated with overall survival (OS) in lung adenocarcinoma (LUAD). In this study, we aimed to explore the clinical significance of PCBP1-AS1 in LUAD and developed a novel prognostic signature based on two eRNAs. Our team discovered that the expression of PCBP1-AS1 was distinctly downregulated in LUAD specimens compared with nontumor specimens. Lower PCBP1-AS1 expression was related to advanced clinical stages and poor prognosis. KEGG analysis unveiled that the coexpression genes of PCBP1-AS1 were involved in the regulation of several tumor-related pathways. In addition, remarkable associations were observed between the expression of PCBP1-AS1 and the levels of several immune cells. Then, we used PCBP1-AS1 and TBX5-AS1 to develop a prognostic model. Survival assays unveiled that patients with higher risk scores exhibited a shorter OS in contrast to patients with lower risk scores. In addition, multivariable Cox regressive analysis indicated that the risk score was an independent prediction factor in LUAD sufferers. The anticancer drug sensitivity analysis indicated that risk score had a positive relationship with several anticancer drugs. Taken together, our findings indicated PCBP1-AS1 as a function modulator in LUAD development. In addition, we constructed a robust immune-related eRNA signature which might be a clinical prognosis factor for LUAD patients.

Published: May 2022

Pedestrians as a vulnerable category of traffic participants demand a special attention, particularly regarding their behavior at unsignalized pedestrian crossings. Unquestionably, when crossing a road at these types of pedestrian crossings, there is a potential risk, for both the pedestrians and other traffic participants, as well. Accordingly, this article shows the research on pedestrians’ behavior at unsignalized intersections, conducted at four locations in the urban environment of Novi Sad. The main goals of this study are reflected in developing a multiphase model by integrating different approaches into one original unique model. First, the efficiency of the observed locations of pedestrian crossings was determined by applying a model consisting of DEA (Data Envelopment Analysis), fuzzy DEA, entropy, CRITIC (CRiteria Importance Through Intercriteria Correlation), fuzzy FUCOM (Full Consistency Method), fuzzy PIPRECIA (PIvot Pairwise RElative Import Criteria Assessment), and fuzzy MARCOS (Measurement of alternatives and ranking according to COmpromise solution). Then, the following aim of this study is to determine the values of the critical interval and then to compare these values with the accepted interval, which can be considered one of the criteria of safe pedestrians’ crossing the roadway. Apart from this, the aim is related to determining the characteristics of pedestrians’ behavior at unsignalized crossings, with a special reference to gender differences, as well to the fact whether the pedestrian crosses the roadway as an individual or within a group. After the empirical research and data classification, efficiency calculation, an extensive statistical and verification analysis was conducted to determine the set goals. The results imply that the relationship of the values of the accepted and critical intervals indicates the occurrence of the risky behavior of a certain number of pedestrians, which is reflected in accepting the intervals that are not completely safe for crossing the roadway and which can negatively affect the sustainable functioning of the traffic system.

We have also attempted to prove an existence theorem for FHDEs under Lipschitz and Caratheodory conditions. We have also presented some fundamental fractional differential inequalities that can be employed to indicate that some external solutions exist for such problems. The required tools are taken into consideration and the principle for comparison is offered which can be used to conduct further research work regarding qualitative behavior of solutions.
Multispectral Remote Sensing Data Analysis Based on KNNLC Algorithm and Multimedia Image
Authors: Sun Yingxin
Published: May 2022

In order to combine multimedia imagery and multispectral remote sensing data to analyze information, preprocessing becomes a necessary part of it. It is found that the KNN algorithm is one of the classic algorithms of data mining. As one of the most important branches in the field of data analysis, it is widely used in many fields such as classification, regression, missing value filling, and machine learning. As a lazy algorithm, this method requires no prior statistical knowledge and no additional data to train description rules and is easy to implement. However, the algorithm inevitably has many problems, such as how to determine the appropriate

K

value, the unsatisfactory effect of data processing for some special distributions, and the unacceptable computational complexity of high-dimensional data. In order to solve these shortcomings, the researchers proposed the KNNLC algorithm. Then, taking the classification experiment as an example, through the comparison of the experimental results on different data sets, it is proved that the average level of the classification performance of the KNNLC algorithm is better than the classic KNN classification algorithm. The KNNLC algorithm shows better performance in most cases, with an accuracy rate of 2 to 5 percentage points higher. An improved algorithm is proposed for the nearest neighbor selection strategy of the traditional KNN algorithm. First, in theory, combined with the theory of sparse coding and locally constrained linear coding, the classical KNN algorithm is improved, and the KNNLC algorithm is proposed. The comparison of the experimental results on the data set proves that the average level of the KNNLC algorithm is better than the classical KNN classification algorithm in terms of classification performance.
A Shunt DC Electric Spring-Based Control Strategy for Real-Time Critical and Noncritical Load Management in DC Microgrid
Authors: Anu A. G. , Harikumar R. , Ushakumari S.
Published: May 2022

Deployment of DC Electric Spring (DCES) technology is an innovative demand side management (DSM) program that helps to mitigate voltage interruptions. Conventional control strategy uses proportional-integral controllers to regulate DC spring parameters. As PI controllers have a trade-off between settling time and peak overshoot, they may not be able to achieve the desired dynamic performance under varying DC microgrid (DCMG) conditions. In this regard, this paper proposes an inverted zero compensator for the control of shunt DCES (ShDCES) in DCMG. This controller regulates the ShDCES current and terminal voltage under all operating conditions with reduced settling time and peak overshoot. A power management algorithm is also proposed to optimize the operation of ShDCES under the presence of varying PV generation and critical and noncritical loads. A detailed mathematical analysis of ShDCES and inverted zero compensator design are furthermore incorporated to validate the strategy. The simulation of the proposed method is performed in MATLAB/Simulink environment. The comparison analysis with the conventional controller proves the effectiveness of the new controller. The results are also validated using real-time simulator OP4510RTS.

Published: May 2022

Hypoxic-ischaemic encephalopathy (HIE) is a severe complication of asphyxia at birth. Therapeutic hypothermia, the standard method for HIE prevention, is effective in only 50% of the cases. As the understanding of the immunological basis of these changes increases, experiments have begun with the use of cord blood (CB) because of its neuroprotective properties. Mechanisms for the neuroprotective effects of CB stem cells include antiapoptotic and anti-inflammatory actions, stimulation of angiogenesis, production of trophic factors, and mitochondrial donation. In several animal models of HIE, CB decreased oxidative stress, cell death markers, CD4+ T cell infiltration, and microglial activation; restored normal brain metabolic activity; promoted neurogenesis; improved myelination; and increased the proportion of mature oligodendrocytes, neuron numbers in the motor cortex and somatosensory cortex, and brain weight. These observations translate into motor strength, limb function, gait, and cognitive function and behaviour. In humans, the efficacy and safety of CB administration were reported in a few early clinical studies which confirmed the feasibility and safety of this intervention for up to 10 years. The results of these studies showed an improvement in the developmental outcomes over hypothermia. Two phase-2 clinical studies are ongoing under the United States regulations, namely one controlled study and one blinded study.

Authors: Li Haiyin , Wu Yan
Published: May 2022

In this study, for COVID‐19, we divide people into four categories: susceptible S(t), closely contacted C(t), infective I(t), and removed R(t) according to the current epidemic situation and then investigate two models: the SCIR models with immigration (Model (2) and without immigration (Model 1). For the former, Model 1, we obtain the condition for global stability of its disease‐free equilibrium. For the latter, Model 2, we establish the local asymptotic stability of its endemic equilibrium by constructing Lyapunov function. Afterwards, by the bifurcation theory, we qualitatively analyze the properties of its Hopf bifurcations of the latter. Finally, numerical simulations are given to illustrate the obtained results of two models. The results imply the importance of finding closely contacted and overseas imports on epidemic control. It indicates that not only the incubation delay τ is crucial for the containment of the COVID‐19 but also the scientific and rigorous containment measures are the key factors of the success of the containment.
A Molecular Insight into the Role of Antioxidants in Nonalcoholic Fatty Liver Diseases
Authors: Ezhilarasan Devaraj , Lakshmi Thangavelu
Published: May 2022

Nonalcoholic fatty liver disease (NAFLD) defines fat accumulation in the liver, and it is commonly associated with metabolic syndromes like diabetes and obesity. Progressive NAFLD leads to nonalcoholic steatohepatitis (NASH) and ultimately causes cirrhosis and hepatocellular carcinoma, and NASH is currently a frequent cause of liver transplantation. Oxidative stress is often contributed to the progression of NAFLD, and hence, antioxidants such as silymarin, silybin, or silibinin, pentoxifylline, resveratrol, and vitamins A, C, and E are used in clinical trials against NAFLD. Silymarin induces the peroxisome proliferator-activated receptor α (PPARα), a fatty acid sensor, which promotes the transcription of genes that are required for the enzymes involved in lipid oxidation in hepatocytes. Silybin inhibits sterol regulatory element-binding protein 1 and carbohydrate response element-binding protein to downregulate the expression of genes responsible for de novo lipogenesis by activating AMP-activated protein kinase phosphorylation. Pentoxifylline inhibits TNF-α expression and endoplasmic reticulum stress-mediated inflammatory nuclear factor kappa B (NF-κB) activation. Thus, it prevents NAFLD to NASH progression. Resveratrol inhibits methylation at Nrf-2 promoters and NF-κB activity via SIRT1 activation in NAFLD conditions. However, clinically, resveratrol has not shown promising beneficial effects. Vitamin C is beneficial in NAFLD patients. Vitamin E is not effectively regressing hepatic fibrosis. Hence, its combination with antifibrotic agents is used as an adjuvant to produce a synergistic antifibrotic effect. However, to date, none of these antioxidants have been used as a definite therapeutic agent in NAFLD patients. Further, these antioxidants should be studied in NAFLD patients with larger populations and multiple endpoints in the future.

Background. Early detection of the SARS-CoV-2 is crucial for both the improvement of turnaround time and limiting the spread of the virus in the community. Thus, this study aims to establish rapid antigen tests as an effective diagnostic tool to improve the testing strategies of COVID-19 diagnosis. Methods. A laboratory based cross-sectional study was performed on the patients that visited Sukraraj Tropical and Infectious Disease Hospital (STIDH) in Kathmandu, Nepal, from November 2020 to January 2021. A total of 213 nasopharyngeal swabs were collected from both symptomatic and asymptomatic patients for rapid antigen test, followed by RT-PCR assay as reference test for confirmation of COVID-19. A standard questionnaire was administered to collect other information from patients. Data were collected and analyzed using SPSS version 20. Results. Out of 213 individuals, 75 tested positive in Ag-RDT test, while 118 tested positive for SARS-CoV-2 RNA genome via Real time PCR assay. The overall diagnostic performance of Ag-RDT showed 63.6% sensitivity and 97.9% specificity. The diagnostic accuracy of Ag- RDT was 78.9% with κ value 0.590, showing moderate agreement with RT-PCR. Significant difference (

p

value <0.001) was observed between Ag- RDT+ and Ag- RDT− results when compared to Cq values obtained from RT- PCR. Conclusion. The promising performance of Ag-RDT renders it useful as screening tool alongside RT-PCR to reduce transmission via improving contact tracing, implementation of local mitigation strategies, and refining existing testing protocol for diagnosis of COVID-19.

Authors: Kannan A. Rajesh , Manivannan P. , Loganathan K. , Gyeltshen Sonam
Published: May 2022

Classical mean labeling of a graph G with p vertices and q edges is an injective function from the vertex set of G to the set {1,2,3, …, q + 1} such that the edge labels obtained from the flooring function of the average of mean of arithmetic, geometric, harmonic, and root square of the vertex labels of each edge’s end vertices is distinct, and the set of edge labels is {1,2,3, …, q}. One of the graph operations is to duplicate the graph. The classical meanness of graphs formed by duplicating an edge and a vertex of numerous standard graphs is discussed in this study.

Introduction: Accumulation of fat tissue around the kidneys is considered to be a risk factor for chronic kidney disease (CKD). The objective of the study was to investigate the association of pararenal fat tissue (PRFT) and renal dysfunction in patients without clinically significant cardiovascular diseases (CVDs). Methods: The study included 320 patients without CVDs (mean age 63.8 ± 13.9 years). All patients underwent anthropometric measurements, standard biochemical blood tests, including a lipid panel and uric acid concentration. Glomerular filtration rate (GFR) was calculated using the CKD-EPI formula. All patients underwent computed tomography of the abdomen with measurement of the PRFT thickness. The research results were processed using StatSoftStatistica 10.0 software. Results: The average PRFT thickness was 1.45 cm [0.9; 2.0]. It was significantly higher in obese individuals when compared with patients with normal body weight (1.9 cm [1.3; 2.6] vs. 1.0 cm [0.6; 1.7]) and overweight people (1.9 cm [1.3; 2.6] vs. 1.1 cm [0.8; 1.6]) (p < 0.001). GFR was significantly higher in subjects with normal body weight when compared with obese patients (72 mL/min/1.73 m2 [59; 83] vs. 61 mL/min/1.73 m2 [51; 70]) and overweight patients (72 mL/min/1.73 m2 [59; 83] vs. 61 mL/min/1.73 m2 [54; 72]) (p < 0.001). PRFT thickness was significantly higher in patients with stage 3 CKD when compared with those with stage 1 CKD (2.2 cm [1.6; 3.3] vs. 0.9 cm [0.9; 1.0]) and with stage 2 CKD (2.2 cm [1.6; 3.3] vs. 1.3 cm [0.9; 1.8]) (p < 0.001). A significant correlation was found between PRFT thickness and body mass index (r = 0.49, p < 0.05), waist circumference (r = 0.55, p < 0.05), GFR (r = −0.47, p < 0.05), and uric acid level (r = 0.46, p < 0.05). Multiple linear regression analysis revealed a significant relationship between GFR and age (β ± SE −0.43 ± 0.15, p = 0.01), PRFT thickness (β ± SE −0.38 ± 0.14, p = 0.01) and with the level of low-density lipoprotein cholesterol (β ± SE −0.32 ± 0.12, p = 0.01). Logistic regression analysis showed that the risk of renal dysfunction development was associated with PRFT thickness (OR = 6.198; 95% CI: 1.958–19.617; p < 0.05). ROC analysis determined the threshold values of PRFT thickness (>1.68 cm, AUC = 0.875), above which the development of renal dysfunction can be predicted (sensitivity 63.2%, specificity 93.4%). Conclusion: The results of our study indicate the relationship between PRFT and visceral obesity and renal dysfunction in patients without clinically significant CVDs.

Published: May 2022

Background: Broad participation in genetic research is needed to promote equitable advances in disease treatment and prevention. Objectives: The objective of the study was to assess motivations for, and concerns about, genetic research participation. Methods: The Genetics in Research and Health Care Survey was sent in winter 2017–2018 to 57,331 adult Kaiser Permanente (KP) members from 7 US regions to assess attitudes about genetic testing in health care and research. The survey included an open-ended question on why members would or would not participate in genetic research. Open text responses to this question were coded in the qualitative analysis software Dedoose and analyzed using a thematic analysis approach. Code summaries were organized by major themes, subthemes, and exemplary quotes. Results: Of the 10,369 participants who completed the survey, 2,645 (25%) provided a comment describing reasons they would or would not participate in research involving genetic testing. Respondents who provided a text comment were 64% female, 49% non-Hispanic (NH) White, 17% Asian/Pacific Islander, 20% Hispanic, and 14% NH Black. The primary themes identified were (1) altruism; (2) decision-making and planning; (3) data use; and (4) data security. These major themes were consistent across each race and ethnic group. Conclusions: To promote broad participation in genetic research, it is important that recruitment materials address the primary motivators for genetic research participation, including altruism and the potential use of results for personal decision-making. Study materials should also address concerns about possible misuse of genetic information and fears over potential data breaches.
Hoffnung auf die künstliche Hornhaut: Aktuelle Möglichkeiten und zukünftige Chancen
Authors: Bachmann Björn
Published: May 2022

Corneal diseases are a leading cause of blindness with an estimated 10 million patients diagnosed with bilateral corneal blindness worldwide. Corneal transplantation is highly successful in low-risk patients with corneal blindness but often fails those with high-risk indications such as recurrent or chronic inflammatory disorders, history of glaucoma and herpetic infections, and those with neovascularisation of the host bed. Moreover, the need for donor corneas greatly exceeds the supply, especially in disadvantaged countries. Therefore, artificial and bio-mimetic corneas have been investigated for patients with indications that result in keratoplasty failure. Two long-lasting keratoprostheses with different indications, the Boston type-1 keratoprostheses and osteo-odonto-keratoprostheses have been adapted to minimise complications that have arisen over time. However, both utilise either autologous tissue or an allograft cornea to increase biointegration. To step away from the need for donor material, synthetic keratoprostheses with soft skirts have been introduced to increase biointegration between the device and native tissue. The AlphaCorTM, a synthetic polymer (PHEMA) hydrogel, addressed certain complications of the previous versions of keratoprostheses but resulted in stromal melting and optic deposition. Efforts are being made towards creating synthetic keratoprostheses that emulate native corneas by the inclusion of biomolecules that support enhanced biointegration of the implant while reducing stromal melting and optic deposition. The field continues to shift towards more advanced bioengineering approaches to form replacement corneas. Certain biomolecules such as collagen are being investigated to create corneal substitutes, which can be used as the basis for bio-inks in 3D corneal bioprinting. Alternatively, decellularised corneas from mammalian sources have shown potential in replicating both the corneal composition and fibril architecture. This review will discuss the limitations of keratoplasty, milestones in the history of artificial corneal development, advancements in current artificial corneas, and future possibilities in this field.

Introduction: This study systematically reviewed scientific evidence concerning the influence of green space on obesity in China. Methods: Keyword and reference search was conducted in PubMed, Web of Science, Scopus, EBSCO, and CNKI. Predetermined selection criteria included study designs: experimental and observational studies; subjects: people of all ages; exposures: green space (i.e., any open land partly or entirely covered with grass, trees, shrubs, or other vegetation); outcomes: body weight status (e.g., body mass index [BMI], overweight, or obesity); and country: China. Results: Ten studies met the selection criteria and were included in the review. All studies adopted a cross-sectional design. Overall greenness measures were found to be inversely associated with BMI, overweight, and obesity in most included studies. Street greenness, which measures the perceived greenness at the eye level on streets, was found to be inversely associated with BMI and obesity. By contrast, mixed results were observed for the relationship between green space accessibility and weight outcomes. Air quality was found to mediate the relationship between greenness and obesity. The influence of green space on obesity tended to vary by residents’ gender, age, and socioeconomic status. Boys, women, older residents, and those with lower education or household income were more likely to benefit from greenness exposure. Conclusion: The literature on green space exposure in relation to obesity in China remains limited. Longitudinal and quasi-experimental studies are warranted to assess the causal link between green space and obesity. Future measures should better capture the self-perception, quality, and attractiveness of green space. The underlying pathways through which green space affects residents’ weight outcomes should be further elucidated.

Taxes are an important revenue of a country to fund state spending and a source of revenue for the state from the public. People have an obligation to pay taxes on their business or activities by referring to the income or results of products or services. Because the payment of this tax is an obligation, community compliance becomes very important to spur state tax revenues. This research aims to determine tax revenue, education, taxpayer awareness of tax compliance. This research method is quantitative, and uses questionnaires with 188 respondents spread throughout Central Java. Researchers have conducted reliability and validity tests, classical assumption tests, and finally regression tests to test all three research hypotheses. The results of all hypotheses are declared accepted, but only the second hypothesis is statistically significant, namely the level of tax education positively affects the level of taxpayer compliance. While the other hypothesis is that the level of tax revenue has a positive effect on the level of taxpayer compliance and the level of taxpayer awareness has a positive effect on the level of taxpayer compliance, declared acceptable although not significant. The conclusion of this study is that tax education has a very positive influence on people's compliance in tax payments. Therefore, tax education in the future will need to be improved to increase the potential payment of taxes to the state. The contribution of this research is that this study can provide insight that education about taxes is still indispensable to increase the country's tax revenues. These directions are written in the format required for the abstract of the paper for the Seminar Nasional Manajemen, Ekonomi, dan Akuntansi – Universitas Bangka Belitung ke IV (SEMEABB IV/ SEMEABB 2021).
Variação em terminologia: capoeira em Belo Horizonte

Neste estudo-piloto analisou-se a variação na terminologia da capoeira em Belo Horizonte. Foram coletados os termos atribuídos por 10 informantes (5 homens e 5 mulheres, com faixa etária entre 25 e 32 anos, professores de capoeira) a 69 movimentos da capoeira gravados em vídeo. Como resultado obtiveram-se 294 termos diferentes conjuntamente, cujos padrões de variação distribuem-se em 15 tipos. Testou-se hipótese de que os termos figurados tenderiam a ser substituídos por não-figurados, o que foi confirmado pelos dados. Essa tendência seria fruto de uma busca de transparência na terminologia, fazendo com que os termos sejam mais descritivos em relação aos movimentos da capoeira.
A representação (anti)feminista na imprensa ilustrada argentina do início do século XX: entre disputas e apropriações
Authors: Moreira Thaís Batista Rosa
Published: May 2022

Uma das grandes pautas políticas do início do século XX foi o sufrágio feminino, questão que mobilizou uma série de militantes, políticos e articulistas, seja em seu apoio, seja em sua oposição. Tendo a imprensa como fonte, o objetivo deste artigo é analisar parte da trajetória feminista argentina a partir de dois periódicos ilustrados: PBT e Caras y Caretas. Além disso, outras fontes da imprensa internacional da época são mencionadas, uma vez que muitas das representações sobre o tema circularam por diferentes países. Para isso, mobilizaremos a concepção de representação de Roger Chartier, as ideias acerca da circulação e da apropriação cultural mencionadas por Angela de Castro Gomes e Patricia Souza Hansen, bem como algumas considerações sobre a história conceitual do político de Pierre Rosanvallon. Nesse sentido, buscamos evidenciar como o debate sobre a emancipação feminina foi permeado por disputas – que envolviam posicionamentos detratores do feminismo e do sufragismo – mas também por apropriações – que as mulheres militantes utilizaram para contrapor os discursos antifeministas em voga, especialmente na imprensa.

Aortic aneurysm is a complex pathology that can be lethal if not detected in time. Although several molecular mechanisms and pathways have been identified to be involved in aortic aneurysm development and growth, the current lack of an effective pharmacological treatment highlights the need for a more thorough understanding of the factors that regulate the remodeling of the aortic wall in response to triggers that lead to aneurysm formation. This task is further complicated by the regional heterogeneity of the aorta and that thoracic and abdominal aortic aneurysm are distinct pathologies with different risk factors and distinct course of progression. ADAMs (a disintegrin and metalloproteinases) and ADAMTS (ADAMs with a thrombospondin motif) are proteinases that share similarities with other proteinases but possess unique and diverse properties that place them in a category of their own. In this review, we discuss what is known on how ADAMs and ADAMTSs are altered in abdominal aortic aneurysm and thoracic aortic aneurysm in patients, in different animal models, and their role in regulating the function of different vascular and inflammatory cell types. A full understanding of the role of ADAMs and ADAMTSs in aortic aneurysm will help reveal a more complete understanding of the underlying mechanism driving aneurysm formation, which will help towards developing an effective treatment in preventing or limiting the growth of aortic aneurysm.
Operaismo and the Wicked Problem of Organization
Authors: Trott Ben
Published: May 2022

The “problem of organization” has long been a core preoccupation of the Marxist tradition and labour movements. This article argues it is best understood as what some social planners call a “wicked problem,” one that cannot ultimately be “solved,” only “re-solved—over and over again.” It identifies a set of hallmark theoretical tools developed by the Italian Marxian tradition of operaismo (sometimes referred to as “autonomist Marxism”) with which it can nevertheless be productively approached. First, a “Copernican inversion” of “orthodox”—specifically, “dialectical materialist”—Marxism, focusing on the primacy of labour struggles in driving capitalist development. Second, an attention to “class composition” and the shifts in the political expression of labour movements as the technical make-up of labour changes. Third, accounting for these shifts through an analysis of “cycles of struggle.” And finally, approaching the (wicked) problem of organization in terms of an effort to increase labour’s “autonomy” from capital.
