Competitive Vertex Recoloring
Authors: Azar Yossi , Machluf Chay , Patt-Shamir Boaz , Touitou Noam
Published: August 2022

Motivated by placement of jobs in physical machines, we introduce and analyze the problem of online recoloring, or online disengagement. In this problem, we are given a set of $n$ weighted vertices and a $k$-coloring of the vertices (vertices represent jobs, and colors represent physical machines). Edges, representing conflicts between jobs, are inserted in an online fashion. After every edge insertion, the algorithm must output a proper $k$-coloring of the vertices. The cost of a recoloring is the sum of weights of vertices whose color changed. Our aim is to minimize the competitive ratio of the algorithm, i.e., the ratio between the cost paid by the online algorithm and the cost paid by an optimal, offline algorithm.
We consider a couple of polynomially-solvable coloring variants. Specifically, for 2-coloring bipartite graphs we present an $O(\log n)$-competitive deterministic algorithm and an $\Omega(\log n)$ lower bound on the competitive ratio of randomized algorithms. For $(\Delta+1)$-coloring, where $\Delta$ is the maximal node degree, we present tight bounds of $\Theta(\Delta)$ and $\Theta(\log\Delta)$ on the competitive ratios of deterministic and randomized algorithms, respectively (where $\Delta$ denotes the maximum degree). We also consider the fully dynamic case which allows edge deletions as well as insertions. All our algorithms are applicable to the case where vertices are weighted and the cost of recoloring a vertex is its weight. All our lower bounds hold even in the unweighted case.

Published: August 2022

Objectives The study aimed to investigate the structural aspects of polymyxins nephrotoxicity at the atomic level to promote the more purposeful development of the polymyxin’s derivatives with the lower nephrotoxic action. Materials and methods The molecular dynamics simulations of the complexes of polymyxin B and its derivative NAB7061 (that carries only three positive charges located within the macrocycle) with megalin were done in program package YASARA Structure with explicit water (TIP3P) and ions (0.9% NaCl) in NPT ensemble using the AMRER03 force field. After 10 ns equilibration, each system was simulated at 298 K and pH 7.4 for a 25 ns production phase. Simulations were run twice for each molecular system. Results By molecular dynamics simulations, the possibility was shown for polymyxin to form a stable complex with two neighbor structural domains of megalin in accord with the universal mechanism of binding the cationic ligands by ligand-binding CR repeats of the LDLR-family receptors. It was shown that interactions of megalin with polymyxin are stronger than with its derivative having no positively charged groups outside the macrocycle. The structural prerequisites of these differences were revealed that explain the less nephrotoxicity of such derivatives compared to polymyxin. Conclusions Comparative molecular dynamics simulations of megalin interactions with polymyxin B and its derivative NAB7061 that carries no positive charges located outside the macrocycle revealed the possible structural prerequisites for the lower nephrotoxic action of such polymyxin derivatives. The weakening of polymyxins binding with megalin may become an effective preventive measure against polymyxin-induced nephrotoxicity.
Space-Resolved Chemical Information from Infrared Extinction Spectra

Published: August 2022

Based on the classical Lorentz model of the index of refraction, a new method is presented for the extraction of the complex index of refraction from the extinction efficiency, Qext , of homogeneous and layered dielectric spheres that simultaneously removes scattering effects and corrects measured extinction spectra for baseline shifts, tilts, curvature, and scaling. No reference spectrum is required and fit functions may be used that automatically satisfy the Kramers-Kronig relations. Thus, the method yields pure absorbance spectra for unambiguous interpretation of the chemical information of the sample. In the case of homogeneous spheres, the method also determines the radius of the sphere. In the case of layered spheres, the method determines the substances within each layer. Only a single-element detector is required. Using simulated Qext data of polymethyl-methacrylate and polystyrene homogeneous and layered spheres, we show that our reconstruction algorithm is reliable and accurately extracts pure absorbance spectra from Qext data. Reconstructing the pure absorbance spectrum from a published, experimentally measured raw absorbance spectrum shows that our method simultaneously corrects spectra for scattering effects and, given shape information, corrects raw spectra for systematic errors that result in spectral distortions such as baseline shifts, tilts, curvature, and scaling.

Published: August 2022

Primary Sjögren's syndrome (pSS) is a chronic autoimmune disease that affects exocrine glands, such as salivary and lacrimal glands. The Janus kinase (JAK) /signal transducer and activator of transcription (STAT) pathway are activated in various inflammatory diseases including pSS. This study aimed to investigate the expression of JAK1, JAK2, phosphorylated JAK1, and phosphorylated JAK2 in labial salivary gland (LSG) tissues from patients with pSS to evaluate the potential of JAK inhibitors as therapeutic agents for pSS. Immunohistochemical analysis was performed using LSG tissues of patients with pSS (n=10), non-SS (n=5), and healthy controls (n=5). In acinar epithelial cells, JAK1, JAK2, and phosphorylated JAK1 were expressed at significantly lower levels in LSG tissues of patients with pSS than in healthy controls. Significantly higher expression of phosphorylated JAK1 and phosphorylated JAK2 was observed in the ductal epithelial cells of patients with pSS compared to the controls. However, there was no significant association between the expression levels of phosphorylated JAK1 or JAK2 and the degree of inflammation. In addition, immunofluorescence analysis revealed JAK2 phosphorylation in many CD3 + T cells infiltrating the LSG tissues. These results suggested the activation of JAK/STAT signaling in both the ductal epithelial cells and the infiltrating CD3 + T cells in the LSG tissues of patients with pSS. Therefore, JAK inhibitors may be effective therapeutic agents for pSS by regulating both effector T cells and target cells.

Background: PNC is the care given to the mother and her newborn baby immediately after the birth and for the ﬁrst six weeks of life. This study aimed to analyze the spatial clustering of PNC utilization and identify associated factors in Ethiopia.Methodology: This study has been conducted in Ethiopia based on data obtained from EDHS 2016which mainly focused on the PNC utilization of mothers reproductive age. The risk of PNC use was also model and map using a Bayesian hierarchical spatial model under MCMC approach using R.Results: In Ethiopia, the prevalence of women’s PNC usage was found to be 9.4% with marked spatial heterogeneity. The global Morans I and Gearys C test statistics show signiﬁcant spatial clustering among neighboring regions in the study area. Bayesian hierarchical model with spatial unstructured and structured eﬀects was found to be the appropriate model.Conclusion: The prevalence of PNC utilization in the study area is signiﬁcantly clustered indicating high levels in Tigray region and Addis Ababa city whereas low levels in eastern, southeastern and northern part of Ethiopia. Risk factors such as women with secondary and above educational status, richest wealth index, secondary and above educational status of husband, birth size, media exposure, employment status and at least four number of ANC visits were signiﬁcantly associated with PNC utilization.
Trait anxiety modulates the detection sensitivity of negative affect in speech
Authors: K Achyuthanand , Prasad Saurabh , Chakrabarty Mrinmoy
Published: August 2022

Auditory perception of emotions in speech is relevant for humans to optimally navigate the social environment. While sensory perception is known to be influenced by bodily internal states such as anxiety and ambient noise, their relationship to human auditory perception is relatively less understood. In a supervised, internet-based experiment carried out sans the artificially controlled laboratory environment, we asked if the detection sensitivity of emotions conveyed by human speech-in-noise (acoustic signals) is modulated by individual differences in internal affective states, e.g., anxiety. In a task, participants (n = 24) accurately discriminated the target emotion conveyed by the temporally unpredictable acoustic signals (signal to noise ratio = 10dB), which were manipulated at four levels (Happy, Neutral, Fear and Disgust). We calculated the empirical area under the curve (measure of acoustic signal detection sensitivity) based on signal detection theory to quantify our results. Specifically, Disgust and Fear detection sensitivities worsened with increasing severities of trait-anxiety. Further, a similar effect was evident when averaging across all emotions. Altogether, the results suggest that individual trait-anxiety levels moderate the detection of emotions from speech-in-noise, especially those conveying negative/threatening affect. The findings may be relevant for expanding the understanding pertaining to auditory perception anomalies underlying affective states and disorders.

Published: August 2022

Background: The bone marrow aspiration and biopsy (BMAB) is an important and frequent investigative procedure for hematological diseases. Although thought to be safe and well tolerated; data is limited on the complications and degree of pain experienced by patients undergoing BMAB. Further scarce is data from India and other regions from the developing world especially given the evidence that cultural factors that could shape pain perception. Adverse events following bone marrow biopsy are rare but poorly documented. Aims: To estimate the level of pain and frequency of serious adverse events experienced by patients undergoing BMAB at our center. We also attempted to identify factors associated with increased pain perception.Methods: Study setting: This study was conducted at a tertiary level teaching hospital, the Christian Medical College & Hospital, Ludhiana. Ethics approval was obtained from the Institutional research committee (CMC/1495).Study period: 01 April 2015 through 30 Nov 2019Study Design: This is a comparative cross-sectional study where comparison of those with relatively more pain to those with less was done to elicit the factors associated with pain perception. Results: A total of 942 BMAB procedures were performed in this period ( Table1). The major serious adverse event was hemorrhage, which comprised 2 of the 9 serious adverse events. The following risk-factors were associated with increased pain on Multivariate analysis: those with prior BMAB had very low odds of pain (OR (95 % CI): 0.23 (0.15–0.37)). However, when more than one attempt of biopsy was made the odds of pain was much higher (OR (95 % CI): 1.62 (1.29–2.05)). Conclusions: In our analysis BMAB is safe and associated with a low level of perceived pain. Serious adverse events following BMAB are rare, but can have considerable impact on the individual patient.

Published: August 2022

Ischemic stroke (IS) has a high mortality and disability rate worldwide. NAF-1 is involved in the occurrence and development of nervous system diseases, but its involvement in the pathophysiology of IS is unclear. In this study, we investigated the role of NAF-1 in IS. Middle cerebral artery occlusion and reperfusion in Sprague-Dawley rats was used as an in vivo model of IS. Moreover, oxygen-glucose deprivation and reoxygenation of PC12 cells was used for in vitro study. Intracellular NAF-1 protein expression was influenced by LV-NAF-1 or siRNA. Quantitative real-time PCR and western blot analysis showed that NAF-1 was significantly downregulated following IS. Overexpression of NAF-1 reduced mitophagy in PC12 cells, and it alleviated tissue damage in vivo in rats and cell injury in vitro. In contrast, knockdown of NAF-1 increased mitophagy and worsened cell damage. These findings suggest that NAF-1 may have potential as a therapeutic target for IS.

Published: August 2022

Viral infections mainly occur in indoor environments, it is suggested that visible light-sensitive antiviral photocatalyst is highly desired. Here we developed a photocatalysis system based on zinc hydroxide (Zn(OH)2) to efficiently generate antiviral radicals on mask surface under weak visible light. The weak visible light induced the Zn(OH)2 photocatalysis and completed the inactivation of H1N1 virus for short time. In addition, the inactivating efficiency was improved greatly by adding a natural washing agent layer. Our system could inactivate H1N1 influenza virus completely rapidly under the irradiation of weak visible light. The discovery will open up a new research field, and enrich and promote the development of photocatalysis theory and practice.
Performance of Semi-Distributed Hydrological Models in Stream Flow Simulation
Authors: Sime Chala Hailu
Published: August 2022

Hydrological measurements are vital for Water Resources Planning and Management. Modeling rainfall-runoff may be used to understand the impact of future hydrological changes such as flooding, soil loss, and sedimentation effect on lakes and reservoirs for irrigation and hydropower. But the difficult one is the selection of the best models. All hydrological models may not be equally performed due to being influenced by input data and over models system that will be used for the analysis. Therefore, two hydrological models; Soil and Water Assessment Tool (SWAT), and Hydrologic Engineering Centers Hydrological Modeling System (HEC-HMS) models to simulate rainfall runoff. These models were calibrated and validated using daily observed streamflow data. The R2 and NSE were used to check the performance of the models and the result indicates that during HEC-HMS model calibration and validation, R2 of 0.6 and 0.61, NSE of 0.55 and 0.53, generated respectively. During the SWAT model accuracy assessment, the values of model performance indicators were R2 of 0.69 and 0.68, NSE of 0.58 and 0.52 for calibration and validation respectively. This indicates both SWAT and HEC-HMS models have been satisfied in streamflow simulations. The SWAT model overestimated the daily streamflow more than the observed and HEC-HMS simulated streamflow. These models overestimated peak streamflow during both the calibration and validation period. The curve number grid generated by HEC-GeoHMS was slightly lower than the curve number simulated by the SWAT model.

Authors: Fernández-Cuadros Marcos Edgar , Pérez-Moro Olga Susana , de Cía Javier Rodríguez , Albaladejo-Florín María Jesús
Published: August 2022

The knee is the second most common site of osteonecrosis (ON) after the hip. Three different entities are described: a) spontaneous ON; b) secondary ON; c) post-arthroscopy ON. In spontaneous ON the etiology is attributed to subchondral insufficiency fractures and to avascular necrosis due to ischemic events. Diagnosis is based on clinical and radiological basis (radiography, bone scan scintigraphy and MRI). Koshino´s radiological classification grades severity and guides in the management. Conservative management includes protected weight bearing, drugs (NSAIDs, bisphosphonates, D vitamin, calcium, prostaglandin I-2, corticosteroids, hyaluronic acid), physiotherapy (laser, pulsed electromagnetic fields), and hyperbaric oxygen therapy. Surgical treatment is deserved for advanced stages or if conservative treatment failed. In pre-collapse Stage, joint preserving procedures are expected; on the contrary, in subchondral collapse stages, joint arthroplasty is required. We present for the first time in literature the beneficial effect of intra articular ozone in the management of two cases of advanced ON of the knee.
Flexible non-parametric regression models for compositional response data with zeros
Authors: Tsagris Michail , Alenazi Abdulaziz , Stewart Connie Connie
Published: August 2022

Compositional data arise in many real-life applications and versatile methods for properly analyzing this type of data in the regression context are needed. When parametric assumptions do not hold or are difficult to verify, non-parametric regression models can provide a convenient alternative method for prediction. To this end, we consider an extension to the classical k--NN regression, termed α--k--NN regression, that yields a highly flexible non-parametric regression model for compositional data through the use of the α-transformation. Our model is further extended to the α--kernel regression by adopting the Nadaraya-Watson estimator. Unlike many of the recommended regression models for compositional data, zeros values (which commonly occur in practice) are not problematic and they can be incorporated into the proposed models without modification. Extensive simulation studies and real-life data analyses highlight the advantage of using these non-parametric regressions for complex relationships between the compositional response data and Euclidean predictor variables. Both suggest that α--k--NN and α-kernel regressions can lead to more accurate predictions compared to current regression models which assume a, sometimes restrictive, parametric relationship with the predictor variables. In addition, the α--k--NN regression, in contrast to current regression techniques, enjoys a high computational efficiency rendering it highly attractive for use with large scale, massive, or big data.
Multiple Sclerosis and risk of eight Adverse Events in Pregnancy: a Mendelian Randomization study
Authors: Tu Hengjia
Published: August 2022

Background
Observational studies have found an association between multiple sclerosis (MS) and some adverse events in pregnancy, but the causal effect between them is unclear.
Methods
Using data from large-scale genome-wide association studies (GWAS), we performed two-sample Mendelian randomization (MR) analysis to comprehensively assess the causal relationship between MS and the risk of eight adverse events in pregnancy (gestational hypertension, diabetes mellitus in pregnancy, ectopic pregnancy, mental disorders, hemorrhage in pregnancy, intrahepatic cholestasis of pregnancy, infections of genitourinary tract in pregnancy, and postpartum hemorrhage).
Results
MR analysis found that MS significantly reduces the risk of diabetes mellitus in pregnancy [OR = 0.8718186, 95%CI (0.8298085, 0.9159556), P < 0.0001] and intrahepatic cholestasis of pregnancy [OR = 0.8813462, 95%CI (0.8052561, 0.9646262), P = 0.0061]. However, the causal effect of MS on the other six adverse events (gestational hypertension, ectopic pregnancy, mental disorders, hemorrhage in pregnancy, infections of genitourinary tract in pregnancy, and postpartum hemorrhage) was not statistically significant.
Conclusion
We found that MS significantly reduced the risk of diabetes mellitus in pregnancy and intrahepatic cholestasis of pregnancy, and the causal effect of MS on other six adverse events (gestational hypertension, ectopic pregnancy, mental disorders, hemorrhage in pregnancy, infections of genitourinary tract in pregnancy, and postpartum hemorrhage) is unclear.

Authors: Singh Nirbhow Jap , Chopra Vikram , Pandey Sandeep , Singh Shakti
Published: August 2022

This paper proposed a novel artificial bee colony with predation effect (ABCPE) algorithm for tuning a proportional integral derivative (PID) controller. The mathematical model of ABCPE algorithm to introduce predator effect in the foraging behavior of artificial bees colony algorithm has been formulated. The proposed algorithm has been tested on tuning problems of different process models. The simulation results reveal that the closedloop responses are relatively fast and non-oscillatory as compared to the Ziegler-Nichols criteria. Further, the results obtained using ABCPE are also compared with other evolutionary algorithms. The exhaustive analysis shows that the ABCPE based solution approach leads to a set of tuning parameters having smaller overshoot, less setting time and rise time compared to other solution approaches. The stability analysis using Nichols plot reveals that the phase margin of proposed algorithm is higher as compared to other tuning methods.
A Novel Ferroptosis-related Gene Signature for Prognosis Prediction in Glioma
Authors: Lan Tian , Wu Die , Quan Wei , Yu Donghu , Li Sheng , Yao Jie , Li Zhi-Qiang
Published: August 2022

Background
Glioma is a lethal brain tumor characterized by its invasive nature, fast growth, and malignant recurrence. Despite aggressive surgical resection, concomitant concurrent radiation, and chemotherapy, the overall survival (OS) of patients with glioma remains low. Ferroptosis is a unique modality that regulates programmed cell death and is associated with multiple steps of tumorigenesis in a variety of tumors. As ferroptosis is an oxidative-stress-induced form of cell death and is related to the intracellular iron level that is intricately linked to cell metabolism, cancer cells may have a higher proclivity for it.
Methods
Genes relevant to ferroptosis were retrieved, and differential analysis was performed, followed by prognosis-related univariate and multivariate Cox regression analyses. A ferroptosis-involving model was also identified. Each sample’s risk score was statistically weighted by gene expression and stratified into high-risk and low-risk groups based on the cut-off value of the ROC curve. GO, KEGG, and GSVA analyses were used to detect probable biological functions and signaling pathways. All independent risk factors were included to build nomograms, and their accuracy and practicability were tested using the concordance index (C-index) and ROC curves. Immune cell infiltration was quantified using CIBERSORT software. Drug response and tumor mutation burden (TMB) were used to verify the effectiveness of the clinical use of immune-targeted therapy.
Results
The patient samples were stratified into two risk groups based on a four-gene signature. The high-risk group had poorer overall survival. The results of the functional analysis indicated that the extracellular matrix-related biological and interferon-gamma-mediated signaling pathway functions were enriched in the high-risk group, and multiple immune pathways were saturated in the GSVA analysis. The infiltration of immunocytes differed between the two groups. At multiple immune checkpoints, the risk score showed a strong positive correlation. The analysis of drug treatment response and TMB showed that the high-risk group had a better treatment response and better curative effect on immune target therapy. The CNV data analysis showed a correlation between the four genes in glioma and different CNV subtypes related to OS in glioma. Besides, we compared the published signatures of ferroptosis-related genes and found that our model performed well in evaluating glioma patients' prognosis in the new WHO CNS5 classification.
Conclusions
A novel ferroptosis-related gene signature, which can classify glioma patients into subgroups, can be used for prognostic prediction in glioma. The four-gene model in the clinical application could serve as a potential method to assess glioma patients' prognosis and response to therapy.
Crystal gravity
Authors: Zaanen Jan , Balm Floris , Beekman Aron
Published: August 2022

We address a subject that could have been analyzed century ago: how does the universe of general relativity look like when it would have been filled with solid matter? Solids break spontaneously the translations and rotations of space itself. Only rather recently it was realized in various context that the order parameter of the solid has a relation to Einsteins dynamical space time which is similar to the role of a Higgs field in a Yang-Mills gauge theory. Such a "crystal gravity" is therefore like the Higgs phase of gravity. The usual Higgs phases are characterized by a special phenomenology. A case in point is superconductivity exhibiting phenomena like the Type II phase, characterized by the emergence of an Abrikosov lattice of quantized magnetic fluxes absorbing the external magnetic field. What to expect in the gravitational setting? The theory of elasticity is the universal effective field theory associated with the breaking of space translations and rotations having a similar status as the phase action describing a neutral superfluid. A geometrical formulation appeared in its long history, similar in structure to general relativity, which greatly facilitates the marriage of both theories. With as main limitation that we focus entirely on stationary circumstances -- the dynamical theory is greatly complicated by the lack of Lorentz invariance -- we will present a first exploration of a remarkably rich and often simple physics of "Higgsed gravity".

Published: August 2022

Digital Financial Services (DFS) have been growing steadily all over the world. The COVID-19 crisis has reinforced the need for DFS. This study aims to examine the growth of DFS in the global and Indian markets and to analyze the factors that change the mindsets and attitudes of adults towards the adoption of DFS during the pandemic. The growth of DFS is analyzed using secondary data. The changing customer mindset is studied and analyzed through primary data collected by a survey approach. The unit of analysis includes adults who use or prefer to use DFS. A total of 384 respondents, determined by Krejcie and Morgan formula, were personally interviewed. 384 is taken as sample size as this sample size avoids type II errors in the data analysis. The collected data were processed in SPSS21 software. The study results found that technological benefits (67.9%) have the most significant positive effect on changing people’s mindsets and attitudes towards DFS followed by the pandemic forces (50.7%). Peer influences (33.2%) and perceived trust (38.3%) have also affected the change in mindsets and attitudes of adults regarding DFS. But the change in mindset is significantly and positively influenced by perceived risk (50.1%) rather than affecting negatively. So, the factors are confirmed again. The factors that drive changes in mindsets and attitudes of adults towards the adoption of DFS are Pandemic Forces & Convenience, Perceived Safety and Security, User Benefits and Experiences, Peer Influences, and Perceived Trust during the pandemic.
Metal Oxide Films as Charge Transport Layers for Solution-Processed Polymer Light-Emitting Diodes
Authors: de Morais Andreia , de Freitas Jilian
Published: August 2022

Here, we discuss the use of metal oxide films as charge transport layers in polymer light-emitting diodes containing poly(9,9-dioctyl-9H-fluorene-2,7-diyl) (PFO) as emissive layer. A simple device architecture consisting of glass-ITO | poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) | poly(9-vinylcarbazole) (PVK) | PFO | Ca | Al was used as starting point. This device assembly allows the investigation of basic properties of polymeric emitting layers, but does not provide stable devices with high performances. Thus, a more complex, multilayered diode structure is needed. We pursuit that goal with focus on the use of low-cost, easily processed materials. At one side, solution-processed non-stoichiometric MoOx films were used to replace the PEDOT:PSS as hole transport layer. At the other interface, solution-processed ZnO films containing either the bare oxide or a ZnO/carbon dots composite were introduced as electron transport layer. By tunning the characteristics of the metal oxide films, the performance of the blue-emitting PFO-based polymer light-emitting diodes (PLEDs) was massively enhanced.

Purpose - This paper aims to explain religious freedom in the context of Islamic Da’wa according to the interpretation of the Qur'an.Method - This study used a qualitative approach to literature (library research) with thematic methods.Result - The results of this study have explained that religious freedom is one of the values guaranteed in Islamic Da’wa. In addition to strictly prohibiting religious coercion on everyone, the Qur'an also clarifies the limits of the missionary duties of the Prophets and scholars (dā'i), which is only to convey the truth of Islamic teachings continuously to humanity by calling on them with the wisdom, the good advice ( mauidzah hasanah ), the best dialogue (jidāl ahsan), and the good example (qudwah hasana ). The Qur'an also emphasizes the diversity of human attitudes in accepting Islamic Da’wa is a sunnah of Allah SWT ., so any attempt to force them to become believers is impossible. The essence of this meaning is at least contained in the interpretation of al-Baqarah: 256, Yūnus : 99 and al-Gāsyiyah : 21-22.Implication - This study suggests a humanist Da’wa that always respects the freedom of mad'u in determining their religion without any element of coercion.Originality - This study is the first study that tries to analyze religious freedom from the perspective of Islamic Da’wa.***Tujuan - Tulisan ini bertujuan untuk menjelaskan kebebasan beragama dalam konteks dakwah Islam menurut tafsir Al-Qur'an.Metode – Penelitian ini menggunakan pendekatan kualitatif kepustakaan (library research) dengan metode tematik.Hasil - Hasil penelitian ini menjelaskan bahwa kebebasan beragama merupakan salah satu nilai yang dijamin dalam dakwah Islam.

Teaching is considered a high-risk profession for suffering from burnout syndrome. Burnout syndrome not only affects the person who suffers from it, but also everyone around them, e.g., family, friends, co-workers, students and parents. The main purpose of this study was to find the correlates of burnout in EFL teachers. Thus, it was conducted to investigate any probable relationship between Iranian EFL teachers’ educational belief and their tendency to self-disclose with their likelihood of suffering from burnout. The research instruments were The Teacher Self-Disclosure Scale (Cayanus and Martin, 2008), Maslach Burnout Inventory (MBI-ES) (Maslach and Jackson, 1981), and Teachers' Educational Belief Questionnaire (Chan Elliot, 2004). The participants were 98 EFL teachers selected from 25 private language schools in Shiraz, Iran. Descriptive statistics, Cronbach Alpha coefficients, and Person Product-Moment Correlation Coefficient were used to answer this research questions. Analyzing the data collected through the questionnaires indicated that there was a positive correlation between some dimensions of teacher burnout and those of teachers’ constructive or traditional beliefs. Thus, ‘lack of personal achievement’ and ‘constructive beliefs’, ‘emotional exhaustion’ and ‘depersonalization’ and teachers’ traditional beliefs were positively correlated. Conversely, a negative correlation was identified between ‘lack of personal achievement’ and teachers’ traditional beliefs. Likewise, ‘emotional exhaustion’ and ‘depersonalization’ on the burnout scale were correlated with teachers’ constructive beliefs.  However, no significant correlation was observed between teachers’ neutral beliefs and any dimensions of the burnout scale. Moreover, teacher self-disclosure quantity and negativity were found to be corelated with ‘emotional exhaustion’ and ‘depersonalization’ on the burnout scale.

A distribution transformer is one of the most important equipments in the power grid, and its operational status is directly related to the security and stability of the entire power system. The performance of transformer windings determines the service life of the transformer. It is of great significance to evaluate the performance of transformer windings accurately, reliably, and effectively after the short-circuit test of the transformer. Aiming at the problem that the natural vibration frequency of the transformer measured before and after the short circuit may not be the same under the impact of the short circuit of the transformer, this paper puts forward the evaluation method for the performance evaluation of the winding of the transformer after the short circuit test and adopts the method of combining the analytic hierarchy process with the fuzzy evaluation method to quantitatively obtain the score for the performance evaluation of the winding. And that evaluation language is given according to the score. Finally, the evaluation of the transformer winding performance after the short-circuit test is realized. The evaluation results show that this method can effectively get the performance index of the transformer winding, without the need for hanging cover inspection, and solve the subjectivity of human eye observation to objectively, accurately, and quantitatively describe the performance state of the transformer winding. The method is favorable for power grid monitoring and maintenance personnel to accurately evaluate the operation stability of the transformer and has very positive significance for improving the short-circuit impact resistance of the transformer and ensuring the safety and stability of the operation of a power system.

Today the remote working becomes more and more broadly implemented in organizations, so they need to adjust by developing distant onboarding practices, which makes the problem of the effective remote adaptation really important. The purpose of the article is to identify, classify and determine the prevalence of remote adaptation practices for new employees in the Russian market, as well as to study the relationship between the assessment of the positive experience of participation in remote adaptation practices and the effectiveness of adaptation through the prism of new employee perception. The empirical research was carried out in two stages including qualitative and quantitative methods. Based on the results of the interviews, 44 remote adaptation practices were classified, and the most frequently used practices were identified. The survey results showed a significant positive relationship between the integral assessment of the experience of participation in adaptation practices with each of the three scales of subjective assessment by newcomers of the adaptation effectiveness: satisfaction, loyalty and productivity. A significant connection was also revealed between the studied constructs and organizational socialization, which acts as a partial mediator of the relationship between the practices of remote adaptation and the results of adaptation.

The presence of toxic algae, such as Microcystis aeruginosa (MA), in drinking water treatment plants (DWTPs) would contribute to algal organic matter (AOM) as precursors toward disinfection by-products (DBPs). Electrocoagulation–flotation (ECF) has shown promising performance in minimizing algal cells from water and dissolved AOM. This study aimed to investigate the effect of current density (CD) and pH on alumina (Al)-based ECF for removing MA cell and DBPs precursors from cyanobacteria-laden water. The performance of Al-based ECF was evaluated at various CD and pH conditions within 20 min. In addition, the total halogenated DBPs formation of the treated suspension after ECF was quantified. At pH 8, the ECF process with 5 mA/cm2 exhibits the most significant reductions in MA cell and soluble AOM, accounting for 97 and 56%, respectively. Additionally, the precursors of trihalomethanes (THMs) and haloketones (HKs) can be effectively removed with flotation despite their significant release at EC. The tremendous reduction of humic acid-like (HAL) substances in extracellular organic matter (EOM) fraction by ECF leads to the minimized THMs formation potential. In summary, Al-based ECF at pH 8 is effective to remove cyanobacteria and minimize the precursors of regulated THMs along with an insignificant reduction in regulated haloacetic acids (HAAs) precursors.

The Michael addition is an important, highly efficient, and atom-economical method for the diastereoselective and enantioselective C-C bond formation. MA used in the synthesis of natural products and drugs is tandem sequenced reactions. An important tandem sequence of Michael and Aldol additions is the Robinson annulation. MA is a versatile reaction employed for efficient bond formation between electron-poor olefins as Michael acceptors with varied nucleophiles as Michael donors. Apart from being involved in C-C bond formation, MA is also employed in the formation of C-X bond (X=O, N, S, P etc.) giving rise oxa-, aza-, thia-, phospha-Michael addition products. In recent years many articles have been published on MA. The mechanism of MA gives an insight into the reaction is initiated by the base. The present review provides comprehensive information on recent advancements in base-assisted Michael addition reactions including varied organic and inorganic bases, such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), 1,4-Diazabicyclo[2.2.2]octane (DABCO), 4-dimethylaminopyridine (DMAP), triethylamine (Et3N), tributylamine (Bu3N), N,N-diisopropylethylamine (DIEPA), diethylamine (NHEt2), guanidine derivatives, and bifunctional thiourea. A variety of inorganic bases including metal alkoxides, metal acetates, metal hydroxides, metal hydrides, metal carbonates, metal halides, and triphenylphosphine (TPP) can also be successfully used in Michael reactions.
Graft Copolymers of Polysaccharide: Synthesis Methodology and
Biomedical Applications in Tissue Engineering
Authors: Malviya Rishabha , Singh Arun Kumar
Published: August 2022

A polymer is a macromolecule that has a significant number of repeating units. It is
possible to modify the architecture of a polymer via grafting, bridging, mixing, or generating composites.
There are several uses for using natural polymers in culinary and medicinal applications.
Polymeric materials became appealing because of their low density and ability to incorporate
properties of their constituent constituents. High-energy accelerated electrons from the plasma
induce chemical bond breaking in the polymeric structure, resulting in the generation of macromolecule
radicals and graft copolymerization. Polymer grafting has become an important aspect of
the formulation development process. When polymer functional groups are changed, a wide variety
of desirable and unwanted properties can be added or removed. It can be concluded from the
findings of the literature survey that graft copolymers of polysaccharides have significant
biomedical applications including drug delivery and tissue engineering applications.
