Authors: Shakagori Shiori , Nawa Nobutoshi , Tabuchi Takahiro , Takahashi Hidehiko , Fujiwara Takeo 
Published: December 2022

Abstract
Purpose: Benevolent sexism, defined as glorifying behaviors found to follow traditional gender roles, can lead to gender inequity and prejudice. Recent studies revealed the dark side of social capital on health through discrimination against outsiders. In the context of benevolent sexism, men and women who do not conform to traditional gender roles may be subject to discrimination. However, empirical studies on the association between social capital and benevolent sexism belief are scarce. We aimed to examine the association between social capital and benevolent sexism belief.
Methods: This study used data from a large online survey conducted from September to October 2021 in Japan (n = 27,952; 13,752 men and 14,200 women). We measured benevolent sexism belief by the Benevolent Sexism Scale for Japanese and individual-level social capital via a questionnaire. We examined associations between both individual-level social capital and prefecture-level social capital, and benevolent sexism after adjusting for covariates, stratified by sex.
Results: Among men, both individual-level and prefecture-level social capital were associated with higher benevolent sexism beliefs (coefficient: 0.20 (95%CI: 0.09, 0.32) and 0.17 (95%CI: 0.01, 0.33), respectively). In contrast, among women, individual-level social capital was inversely associated with benevolent sexism belief (coefficient −0.43 (95%CI: −0.54, −0.31)), and prefecture-level social capital was not associated with benevolent sexism belief (coefficient: 0.03 (95%CI: −0.10, 0.16)).
Conclusion: This study suggested that both individual and community social capital may accelerate benevolent sexism among men, while individual social capital plays a protective role in benevolent sexism among women.

Published: December 2022

Abstract
In this paper, we analyzed the evolution tendency of carbon emissions using the coefficient of variation, the Sen’s slope method and the Mann–Kendall (MK) test, and explored the influence of socioeconomic and environmental factors on carbon emissions by Geodetector, in Qingdao City. The results shown that: (1) From 2000 to 2020, the area with moderate variation (0.1<Cv<1) and growth trend (β>0) of carbon emissions accounted for 73.8% and 80.8% of the whole city, respectively. The maximum value of carbon emissions increased from 0.66 million to 2.05 million tons, and the average value increased by 58.86 tons/a. The area with the value of carbon emissions higher than 2000t/km2 increased yearly. (2) The carbon emissions decreased gradually from the urban center to the periphery. The urban area had the largest variation degree (Cv=0.32) and a significant growth trend of carbon emissions, while Laixi, Jiaozhou and Pingdu were minor. (3) The socioeconomic factors (GDP density, population density and floor area ratio) had a significant impact on the spatio-temporal differentiation of carbon emissions in Qingdao, and the influence of environmental factors (temperature, elevation, land use type and slope) was weak. The interaction of GDP density and population density had the explanatory power of 81.9% on the spatial distribution of carbon emissions. The research indicated that the carbon emissions increased yearly and existed significant spatio-temporal difference in Qingdao city.

Published: December 2022

Abstract
Introduction:
Medical students in the Netherlands have a relatively low exposure to cardiothoracic surgery and cardiology. This results in discrepancies between starting levels of medical residents and expected standards in clinical practice. Another side effect is the international decline in interest in a career in these cardiovascular fields. To compensate for this, extracurricular education programs focused on cardiothoracic surgery and cardiology have been set up.
This study aims to evaluate the impact and benefits of an extracurricular education program on students' knowledge of cardiothoracic surgery and cardiology and to explore possible factors involved in (academic) career decision making.
Methods:
66 participants were enrolled in the extracurricular education program VECTOR and were included in a cross-sectional cohort study. All participants scored their familiarity with different aspects of cardiothoracic surgery and cardiology prior to and after the course. Data was analyzed using Linear regression and Wilcoxon Signed Rank testing.
Results:
Participants demonstrated a significant trend towards improved familiarity with cardiothoracic surgery and cardiology after the program (p = <.001). Significant increased knowledge scores were reported for all specified subdomains after the course with an increase in academic interest in cardiology (p = <.001) and cardiothoracic surgery (p = <.001). Students revealed that clinical responsibilities and a healthy work-life balance were considered most important when deciding upon their future career.
Conclusion:
This study highlights the benefit of an extracurricular education program in cardiothoracic surgery and cardiology for undergraduates and could possibly aid students in preparing for clinical practice.
Breaking the Barrier 2k for Subset Feedback Vertex Set in Chordal Graphs
Authors: Bai Tian , Xiao Mingyu 
Published: December 2022

Abstract
The Subset Feedback Vertex Set problem (SFVS), to delete $k$ vertices from a given graph such that any vertex in a vertex subset (called a terminal set) is not in a cycle in the remaining graph, generalizes the famous Feedback Vertex Set problem and Multiway Cut problem. SFVS remains $|NP|$-hard even in split and chordal graphs, and SFVS in Chordal Graphs can be considered as a special case of the 3-Hitting Set problem. However, it is not easy to solve SFVS in Chordal Graphs faster than 3-Hitting Set. In 2019, Philip, Rajan, Saurabh, and Tale (Algorithmica 2019) proved that SFVS in Chordal Graphs can be solved in $2^{k}n^{\mathcal{O}(1)}$ time, slightly improving the best result $2.076^{k}n^{\mathcal{O}(1)}$ for 3-Hitting Set. In this paper, we break the ``$2^{k}$-barrier'' for SFVS in Chordal Graphs by giving a $1.619^{k}n^{\mathcal{O}(1)}$-time algorithm. Our algorithm uses reduction and branching rules based on the Dulmage-Mendelsohn decomposition and a divide-and-conquer method.

Published: December 2022

Abstract
Background: Biological nitrogen fixation converting atmospheric dinitrogen to ammonia is an important way to provide nitrogen for plants. Pseudomonas stutzeri DSM4166 is a diazotrophic Gram-negative bacterium isolated from the rhizosphere of cereal Sorghum nutans. Endogenous constitutive promoters are important for engineering of the nitrogen fixation pathway, however, they have not been systematically characterized in DSM4166.
Results: Twenty-four candidate promoters were identified from DSM4166 by RNA-seq analysis. These 24 promoters were cloned and characterized using the firefly luciferase gene. The strengths of fourteen promoters varied from 100 to 959% of the strength of the gentamicin resistance gene promoter. The strongest P12445 promoter was used to overexpress the biological nitrogen fixation pathway-specific positive regulator gene nifA. The transcription level of nitrogen fixation genes in DSM4166 were significantly increased and the nitrogenase activity was enhanced by 23 folds. When the nifHDK nitrogenase genes and nifA were both overexpressed by endogenous strong constitutive promoters, the nitrogen fixation efficiency of DSM4166 was increased by 51 folds.
Conclusions: The endogenous strong constitutive promoters identified in this study will facilitate development of DSM4166 as a microbial cell factory for nitrogen fixation and production of other useful compounds.

Published: December 2022

Abstract
Background: Hepatocellular carcinoma (HCC) seriously threatens human health and life due to its high mortality. Ferroptosis is an emerging therapeutic based on accumulating the abnormal reactive oxygen species (ROS) of cancer cells. However, the therapeutic effect of a single treatment modality is often limited. A combination therapy of ferroptosis and immunotherapy has shown excellent therapeutic efficacy and is widely used for the treatment of cancer. Here, we designed a nanodrug that loaded DHA on Fe3+-doped MnO2 nanosheets (Fe-MnO2/DHA) to treat HCC.
Results: Fe-MnO2/DHA would degrade by the glutathione (GSH) of immunosuppressive tumor microenvironment (TME) to release Fe2+, Mn2+ and DHA, leading to ROS accumulation because of Fenton/Fenton-like reaction and breakage of endoperoxide bridge from dihydroartemisinin (DHA) to amplify oxidative stress. Meanwhile, depleting GSH promoted the inactivation of glutathione peroxidase 4 (GPX4), resulting in lipid peroxide (LPO) accumulation. The resulting LPO and ROS induce ferroptosis and apoptosis of liver cancer cells. Consequently, Fe-MnO2/DHA three-pronged stimulation activates oxidative stress, resulting in high levels of targeted ICD. It could enhance the infiltration of CD4+ T and CD8+ T cells as well as promote macrophage polarization. DHA also acted as an immunomodulator to inhibit regulatory T cells (Tregs) for systemic antitumor.
Conclusion: Fe-MnO2/DHA presents a multimodal therapy for HCC driven by ferroptosis, apoptosis and immune activation, significantly advancing synergistic cancer treatment of HCC. The designed nanodrug can act as a promising platform for HCC treatment.

Abstract

Polyethylene composites reinforced with wood dust from Ceiba pentandra were produced at one proportional variable of wood to polymer ratio. The polymers employed for the study were derived from recycled polyethylene embalmed dihydrogene monoxide bags. Derived homogenous particlesize of 1.00 mm of wood and polyethylene particles were used for production at ascending varying percentage of 40, 50, and 60 for wood and at descending varying percentages of 60, 50, and 40 for polyethylene. The effects of Coptotermes curvignathus attack on weight and mechanical properties of wood polyethylene composites were investigated while the extent of damages was examined. The properties which include weight, density, flexural modulus, flexural strength, compressive strength were determined before and after field exposure. The percentage weight changes were also determined after 12 weeks of graveyard field exposure. The mechanical values obtained before and after termite attacks ranged from 781.03 Kg/cm3 to 810.60 Kg/cm3 for density, 1087.76 Nmm− 2 to 4320.02 Nmm− 2 for flexural modulus, 43.68 Nmm− 2 to 59.14 Nmm− 2 for flexural strength and 18.43 Nmm− 2 to 32.55 Nmm− 2 for compressive strength. The density of the wood polyethylene composites was found to be at peak values when the wood content was at 40% while polyethylene content was at 60%. The wood polyethylene composites made at equal percentage of 50/50 was found to be at lowest values for all properties accessed both before and after termite exposures. The proportional percentage of wood/ polyethylene significantly affects the outcome of weight, density, flexural modulus and compressive strength of the composites after exposure to graveyard under tropical climate. This study revealed that the WPC products can be classified as very durable and durable while WPC at proportional ratio of 40/60 can be adopted for house application in Nigeria.

Published: December 2022

AbstractThis article presents an empirical study of the effect of taxation on the performance of Tunisian companies. The study is based on a sample of 122 large Tunisian companies over the 2015-2019 period. The econometric method used is that of panel data. The results show that corporate income tax, tax incentives, firm size, liquidity, and leverage have significant (negative/positive) effects on the financial performance of Tunisian companies. These results may interest investors, practitioners, and regulators who wish to discover the investment climate in Tunisia. Tax policymakers are urged to lower corporate income tax and maximize the tax incentives to attract domestic and foreign investors. Finally, this paper extends the existing literature by examining the effect of taxation on firm performance in the Tunisian context.JEL Classifications L25; H25; C23.

Published: December 2022

Abstract
Due to potential technological applications in a variety of industries, including electronic devices, telecommunications, magnetism, and the health sector, double perovskite materials have attracted a lot of attention from researchers in recent years. In this article, we develop a new BiBaNiMnO6 is a chemical compound studies of the structural and electrical characteristics of the sol-gel-produced double perovskite material have been discussed under various experimental circumstances. The creation of a single-phase, space group R3̅C, secondary phase-free rhombohedral system is confirmed by the room temperature X-ray diffraction study. Dielectric, impedance, conductivity, and modulus of the sample were all tested at different temperatures (100-360K) and frequencies (1kHz-1MHz), and the results reveal numerous surprising properties of the material. Electrical impedance analysis reveals that the sample is represented by an equivalent electrical circuit that is connected in parallel and contains a resistance, capacitance, and a fractal capacitance CPE. Semicircles of Nyquist plots provide evidence that the material exhibits non-Debye type relaxation behavior. There is a relaxation process in the material, as demonstrated by the analysis of the complex modulus approach, the real and imaginary component as a function of frequency for various temperatures. The Jonscher's power law's detailed investigation of the frequency dependence of conductivity at various temperatures reveals a thermally the conduction mechanism is activated. Electrical conductivity and modulus activation energies are very near, suggesting that the relaxation and conduction processes use the same sort of charge carrier. The two models of conduction are correlated barrier hopping (CBH) and non-overlapping small-polaron tunneling (NSPT). Electrical properties of the produced material are really intriguing. Knowing that capacitors can be employed in electrical fields.

Abstract
While the prognosis and the quality of life of hemophilia A patients have been improved greatly, liver diseases due to hepatitis virus infection from blood products previously administered, which require liver transplantation, are increasing. How to optimize perioperative factor VIII (FVIII) replacement through hemostatic monitoring is critically important in hemophilia A patients undergoing liver transplantation. Clot waveform analysis (CWA) extends the interpretation of measurement curves for activated partial thromboplastin time (APTT) or prothrombin time to provide global information about coagulation abnormalities and disorders such as coagulation factor deficiencies. We performed CWA to monitor perioperative hemostasis in a hemophilia A patient on emicizumab undergoing liver transplantation using a brain-dead donor for liver cirrhosis due to hepatitis virus C infection. To gain accurate results of APTT-CWA as well as of APTT and FVIII activity measurement, plasma samples were treated with anti-idiotype monoclonal antibodies against emicizumab to cancel its interference with the coagulation assays due to binding human activated FIX (FIXa) and FX to functionally mimic FVIIIa. Kinetics of the maximum coagulation velocity and acceleration roughly mimicked that of the FVIII activity. These CWA parameters better correlated with FVIII activity than APTT. The plateaus of them were observed at FVIII activity of 100% or more, likely supporting the protocol for perioperative FVIII replacement. Thus, CWA may measure coagulation potential in hemophilia A patients undergoing liver transplantation, aiding in optimizing perioperative FVIII replacement for proper hemostatic management.
Thermodynamic Analysis of Methyl Orange Anion Association with α-Cyclodextrin Using a Conductometric Approach
Authors: Khouri Sa'ib J. , Altwaiq Abdel mnim M. 
Published: December 2022

Abstract
The electrical conductivities of aqueous solutions of the azo dye methyl orange (sodium salt) were measured at 25.0 °C in the concentration range between 2.103 × 10-4 and 9.255 × 10-4 mol L-1. Molar conductivity values fit the Debye-Hückel-Wager equation for a symmetric electrolyte. The value of the molar conductivity of the sodium salt of methyl orange at infinite dilution is 77.93 ± 0.38 S cm2 mol-1. For the anions of methyl orange, the ionic conductivity at infinite dilution was calculated to be 27.82 S cm2 mol-1. Using the same methodology, a thermodynamic analysis of the association between methyl orange anion and α-cyclodextrin was conducted at 20.0, 25.0, 32.0, and 40.0 °C. The measured molar conductivities decreased as the mole ratio of α-cyclodextrin to methyl orange went below 3. The conductivity measurements were analysed using a model using 1:1 stoichiometry at the four different temperatures. The values of AHo and ASo are determined, as well as a discussion of their relevance.
An Electronic Decision Support System that Considers Risk and Site-Specificity in the Evaluation of Irrigation Water Quality
Authors: du Plessis HM , Annandale JG , Benadé N 
Published: December 2022

Abstract
Irrigators are increasingly challenged to maintain or even increase production using less water, sometimes of a poorer quality, and often from unconventional sources. This paper describes the main features of a newly developed software-based Decision Support System (DSS), with which to assess the Fitness for Use (FFU) of water for irrigation. Included in the analysis are site-specific factors, several non-traditional water constituents, and an assessment of the risk of negative effects. A simplified soil water balance and chemistry model is used to assess the water balance components of a cropping system and the redistribution of solutes within a soil profile. Simulations generate user-friendly, colour-coded output, that highlights expected effects of water constituents on soil quality, crop yield and quality, and on irrigation equipment. Because the DSS uses mainly internationally accepted cause-effect relationships to assess the effect of water quality constituents, it is envisaged that the DSS will find universal acceptance and application among irrigation users. In addition to assessing the FFU of irrigation water, the DSS also caters for calculating so-called Water Quality Requirements (WQR). WQRs represent the threshold levels of water quality constituents for irrigation at specified levels of acceptability or risk. Knowledge of WQRs will assist water resource managers to set site-specific targets for the maximum levels of water quality constituents that can be tolerated in a water source before impacting negatively on successful irrigation.

Published: December 2022

Abstract

Working horses support the livelihoods of smallholder farmers in Egypt but can pose potential zoonotic risk to their handlers such as cryptosporidiosis. Working horses were recruited into the study from 37 villages/areas in two Egyptian governorates. Faecal samples were collected from 607 horses and were examined for Cryptosporidium spp. infection using modified Zielh-Neelsen staining technique. Data about signalment, concurrent disease and level of strongyle infection were collected. The prevalence of Cryptosporidium spp. infection was calculated using a bootstrap method and potential risk factors for the infection were investigated using mixed-effects logistic regression models that included the sampling location as a random-effects variable. The prevalence of Cryptosporidium spp. infection was 28.7% (95% confidence interval = 23.5–33.9). None of the variables investigated including age and sex of the animals were associated with the risk of the infection. The study identified greater prevalence of Cryptosporidium spp. infection in the study area and further studies may be required to genotype these parasites. Personal hygiene such as hand sanitation should be practiced when managing these horses.
