Background

The study was aimed to estimate the true prevalence of human tuberculosis (TB); identify risk factors and clinical symptoms of TB; and detect rifampicin (RIF) sensitivity in three study areas of Bangladesh.

Methods

The cross-sectional study was conducted in three Bangladesh districts during 2018. Potential risk factors, clinical symptoms, and comorbidities were collected from 684 TB suspects. Sputum specimens were examined by LED microscopy. TB hierarchical true prevalence, risk factors and clinical symptoms were estimated and identified using a Bayesian analysis framework. Rifampicin sensitivity of M. tuberculosis (MTB) was detected by GeneXpert MTB/RIF assay.

Results

The median TB true prevalence was 14.2% (3.8; 34.5). Although overall clustering of prevalence was not found, several DOTS centers were identified with high prevalence (22.3% to 43.7%). Risk factors for TB identified (odds ratio) were age (> 25 to 45 years 2.67 (1.09; 6.99), > 45 to 60 years 3.43 (1.38; 9.19) and individuals in families/neighborhoods where a TB patient(s) has (ve) already been present (12.31 (6.79; 22.60)). Fatigue, night sweat, fever and hemoptysis were identified as important clinical symptoms. Seven of the GeneXpert MTB/RIF positive sputum specimens (65) were resistant to rifampicin.

Conclusions

About one in every seven TB suspects was affected with TB. A number of the TB patients carry multi drug resistant MTB. Hierarchical true prevalence estimation allowed identifying DOTS centers with high TB burden. Insights from this study will enable more efficient use of DOTScenters-based TB surveillance to end the TB epidemic in Bangladesh by 2035.
An investigation of bubble resonance and its implications for sound production by deep-water fishes

Published: July 2022

Although the continental slope and abyss comprise the largest habitat on earth, the absence of documented fish sounds from deep waters is striking. Fishes with sexually dimorphic muscles attached to their swim bladders suggests that sounds are likely used in male courtship on the upper, mid and lower continental slope. To investigate the effects of environmental extremes on fish sound production, the acoustic behavior of a driven bubble is examined. This study is also relevant to target strength of sonar returns from fish and hearing in auditory specialist fishes. A bubble is a classic, if imperfect, model for swim bladder behavior since the swim-bladder wall is an anisotropic viscoelastic structure responsible for rapid damping. Acoustic properties of bubbles–including far-field resonant frequency, damping factor, and quality factor–are calculated in warm and cold surface conditions and in cold deep-water (depths 1000 m, 2000 m, and 3500 m) conditions using parameters for oxygen and nitrogen, the dominant gases in swim bladders. The far-field resonant frequency and damping factor of a bubble increase with depth, and the scattering cross-section and quality factor decrease with depth. These acoustic properties scale with undamped oscillation frequency of the bubble and do not vary significantly due to gas type or temperature. Bubbles in the deep-water environments are much less efficient radiators of sound than bubbles near the surface because the far-field radiated power for the same excitation decreases with depth. A bubble at depth 3500 m has a 25 dB loss in radiated sound power compared to the same-radius bubble at the surface. This reduction of radiation efficiency in deep water likely contributes to the absence of fish sound recordings in those environments.
The effect of COVID-19 pandemic on sleep-related problems in adults and elderly citizens: An infodemiology study using relative search volume data
Authors: Cha Eun Jung , Jeon Hong Jun
Published: July 2022

COVID-19 has had a substantial national impact in South Korea, causing negative psychological responses including sleep-related problems. Literature indicates sleep problems among the general population have been reported to be as high as around 35.7% during the first 8 months of COVID-19. Therefore, the aim of this study was to investigate the impact of COVID-19 pandemic on sleep problems among the general population using relative search volume (RSV) data, and whether there are any differences by age and time periods spanning before and during the pandemic. RSV data was collected from the most commonly used search engine in South Korea, NAVER. Search terms were grouped into 4 categories: insomnia, other sleep disorders, sleeping pills, and sleeping pill side effects. Time points were divided into 4 periods, each 7 months long: 7 months before COVID-19 (T0), first confirmed COVID-19 case to 7 months after (T1), 7 to 14 months (T2), and 14 to 21 months (T3). A 2x4 factorial Analysis of Variance was conducted to investigate main effects and interactions between age and time periods. Main effects and interaction effects of age and time periods were significant for all search term groups. For all search terms, both age groups showed dramatic increase from T0 to T1. In age group 60 or above, RSV continued to increase for other sleep disorders and sleeping pill. Insomnia and sleeping pill side effects showed decreasing trend at T3. In general, sudden increase in RSV after occurrence of COVID-19 followed by slow decline were observed. However, for age group 60 or above, RSV values of other sleep disorders and sleeping pills continued to increase, suggesting slower recovery of psychological impact with increasing age. Overall, the results underscore the importance of implementing preventive measures for monitoring sleep problems during the pandemic, especially in the elderly.
Sex-, age-, and organ-dependent improvement of bile acid hydrophobicity by ursodeoxycholic acid treatment: A study using a mouse model with human-like bile acid composition

Published: July 2022

Cyp2a12-/-Cyp2c70-/-double knockout (DKO) mice have a human-like hydrophobic bile acid (BA) composition and show reduced fertility and liver injury. Ursodeoxycholic acid (UDCA) is a hydrophilic and cytoprotective BA used to treat various liver injuries in humans. This study investigated the effects of orally administered UDCA on fertility and liver injury in DKO mice. UDCA treatment prevented abnormal delivery (miscarriage and preterm birth) in pregnant DKO mice, presumably by increasing the hydrophilicity of serum BAs. UDCA also prevented liver damage in six-week-old DKO mice, however liver injury emerged in UDCA-treated 20-week-old female, but not male, DKO mice. In 20-week-old male UDCA-treated DKO mice, conjugated plus unconjugated UDCA proportions in serum, liver, and bile were 71, 64, and 71% of the total BAs, respectively. In contrast, conjugated plus unconjugated UDCA proportions in serum, liver, and bile of females were 56, 34, and 58% of the total BAs, respectively. The UDCA proportion was considerably low in female liver only and was compensated by highly hydrophobic lithocholic acid (LCA). Therefore, UDCA treatment markedly reduced the BA hydrophobicity index in the male liver but not in females. This appears to be why UDCA treatment causes liver injury in 20-week-old female mice. To explore the cause of LCA accumulation in the female liver, we evaluated the hepatic activity of CYP3A11 and SULT2A1, which metabolize LCAs to more hydrophilic BAs. However, there was no evidence to suggest that either enzyme activity was lower in females than in males. As female mice have a larger BA pool than males, excessive loading of LCAs on the hepatic bile salt export pump (BSEP) may be the reason for the hepatic accumulation of LCAs in female DKO mice with prolonged UDCA treatment. Our results suggest that the improvement of BA hydrophobicity in DKO mice by UDCA administration is sex-, age-, and organ-dependent.
The association between psychological burden related to COVID-19 and addictive social media use: Testing the mediational role of anxious affect
Authors: Vally Zahir , Helmy Mai
Published: July 2022

Introduction

The COVID-19 pandemic has had a substantial impact on the normalcy of life. Similarly, social media use (SMU) has increased exponentially. This study examined the association between individuals’ perception of the psychological burden related to the pandemic and addictive SMU.

Method

A cross-sectional study was conducted between February and May 2021 in two national contexts, Egypt, and the United Arab Emirates. Data were gathered from a sample of 1322 participants drawn from a university population who completed measures of psychological burden related to COVID-19, anxious affect, and addictive SMU. Preliminary analyses of the potential association between the study variables were conducted using bivariate correlations followed by a pre-specified mediation model.

Results

At a correlational level, all three study variables were positively associated with each other (r values ranged from .18 to .50 and all p values were < .05). A further mediation analysis confirmed that the total effect of psychological burden on addictive SMU was significant (β = .654, SE = .033, 95% CI .589-.720), and this relationship remained significant with inclusion of the mediator. Significant mediation was evident across the total sample as well as within each country-specific subsample.

Conclusion

These results provide insight into the factors that contribute to the development of addictive SMU in relation to the COVID-19 pandemic. Findings are discussed in relation to the emotion regulation function that SMU might play for individuals in the midst of emotional distress.
A method for finding all connections in the Pantelides algorithm for delay differential-algebraic equations
Authors: Collin Daniel
Published: July 2022

The Pantelides algorithm for systems of delay differential-algebraic equations (DDAEs) is a method to structurally analyse such systems with the goal to detect which equations have to be differentiated or shifted to construct a solution. In this process, one has to detect implicit connections between equations in the shifting graph, making it necessary to check all possible connections. The problem of finding these efficiently remained unsolved so far. It is explored in further detail and a reformulation is introduced. Additionally, an algorithmic approach for its solution is presented.
“It’s not just any teaching program”: The new professionalism, educational inequity and Ako Mātātupu: Teach First New Zealand
Authors: Ramsey Zachary , McFeely Helen , Cusimano Jackie , Crawford-Garrett Katherine
Published: July 2022

In an effort to understand the impact of the international education network, Teach for All, this paper focuses on one Teach For All affiliate program, Ako Mātātupu/TFNZ (AM/TFNZ), to consider how Teach For All and its affiliates are reshaping notions of teacher expertise and professionalism as it defines itself in contrast to university-based teacher education. By drawing on qualitative data, including semi-structured interviews, participant observation, and document analysis, we argue that AM/TFNZ develops a new kind of professional by shifting 1) the purpose of becoming educators 2) the content of teacher education, and 3) the role of teacher educators. Ultimately, AM/TFNZ develops their educators outside of the literature, expertise, or histories of teacher education with a focus on creating a network of innovators capable of disrupting the status quo.

Authors: Anderson Ashlee , Thomas Matthew A. M. , Brewer T. Jameson
Published: July 2022

Teach For America (TFA) has left an indelible mark on education in the United States and worldwide through its expansion via Teach For All. A considerable body of research examines the impact and experiences of teachers who enter the profession via TFA and related organizations, including the ways in which they embody controversial policies and new forms of teacher expertise and professionalism. Scant research, however, has examined the experiences of non-TFA teachers who work alongside them. This instrumental case study draws on interviews with nine non-TFA teachers working in traditional public schools to explore their experiences of interacting with TFA teachers at their schools. The findings focus on the perceived inexperience of TFA teachers as well as the labor expended by non-TFA teachers in support of these novice teachers. The paper also examines experiences of TFA teacher attrition and its impact on other teachers, students, and staff at the schools. The paper concludes by discussing the significance of this study and related research across individual, institutional, and broader structural levels.
The post-truth tyrannies of an evidence-based hegemony
Authors: Wescott Stephanie
Published: July 2022

A trend towards evidence-based practice has developed in policy and practice in the United Kingdom, the United States, and Australia in recent years, evolving to become a powerful hegemonic force. This paper considers this latest impetus to teach according to the mandates of a narrow evidence base as a symptom of the post-truth condition, one that elevates a limited body of evidence to an infallible position. Drawing on interviews with practicing teachers and critical discourse analysis of policy texts, this paper explores the homogenizing effects of a tyrannical evidence-based movement, using Antonio Gramsci’s (1971) writing on the relationship between consent, coercion, and the maintenance of cultural hegemony. This paper argues that the contemporary policy landscape obtains consent from teachers to accept its claims through a coercive paradigm built from a powerful set of hegemonic discourses, such as “what works” and “evidence-based.” These discourses, this paper suggests, need to be considered within the current post-truth context, where the dismissal of research claims is akin to scientific skepticism; a dynamic that places teachers in an impossible bind where the evidence underpinning policy is protected by a paradigm that makes it difficult to question.

Authors: Ryu Se Hui , Hong Ki Hyung , Kim Kyung Yang ,   Korean Society of Augmentative and Alternative Communication
Published: July 2022

Background and Objective: Since messages and concepts are expressed through Augmentative and Alternative Communication(AAC) symbols, learning and training are essential in AAC intervention. In this paper, in order to increase the utilization of AAC symbols by people with communication disorder, we developed a web-based symbol learning system using Korean AAC symbols and examined user satisfaction. Method: For symbol learning and user evaluation, the web-based symbol learning system developed in this study consists of five stages: familiarizing with symbols, finding symbols, expressing symbols, and two stages for learning symbol classification. We conducted a usability test which consisted of quantitative evaluation and Focus Group Interview(FGI). Results: As a result of performing quantitative evaluation, an average score was 4.1 for satisfaction of content and operation. As an early symbol learning stage, it was found to be useful for first-time AAC users who were willing to communicate with other people. The system was also found to be useful as teaching and learning content for AAC facilitators. It could be useful for many types of disabled students, although it was pointed out by some users that accessibility of students with brain lesions disorder should be additionally supplemented. Conclusion: Through the symbol learning system developed in this study, we expect that facilitators and learners can improve their ability to utilize AAC symbols and tools.
„Sie bleiben dort, ich aber kehrte hierher zurück.“

Published: July 2022

Eingangs- und Schlussformeln haben erst seit dem letzten Viertel des neunzehnten Jahrhunderts eine größere wissenschaftliche Beachtung gefunden. Da sie mit dem eigentlichen Märchen in keinem Zusammenhang zu stehen scheinen und in einem gewissen Sinne austauschbar sind, hielt man sie nicht für wichtig. Erst die ‚Entdeckung‘ der Erzählerpersönlichkeit, die Aufwertung des lebendigen mündlichen Erzählens und die Einsicht in die Bedeutung des Publikums weckten nachhaltig die Aufmerksamkeit für die vielfältigen Funktionen von Eingangs- und Schlussformeln: Sie stiften Kontakt zum Publikum und animieren es, sich als Hörende und Sehende der in der Erzählung evozierten fiktiven Welt hinzugeben und diese nicht an einer außerhalb der Erzählung liegenden Realität zu messen. Ebenso geben die Schlussformeln das Signal, sich mit dieser Realität wieder abzufinden.

Green synthesis of nano-propolis and nanoparticles (Se and Ag) from ethanolic extract of propolis, their biochemical characterization: A review
Authors: Barsola Bindiya , Kumari Priyanka
Published: July 2022

Propolis is a natural bee product with phenolic components and flavonoid content. As propolis is hydrophobic, it is poorly absorbed by the body, querying the use of other technologies. This review focuses on the biosynthesis, characterization, and evaluation of some biological activities of nanoparticles (AgNPs and SeNPs). The nanoparticles were generated utilizing bee propolis extract, taking into account the benefits of green nanoparticle synthesis. Due to the smaller size, nano-propolis is more easily absorbed by the body. Nano-propolis has the potential to improve efficacy in the realms of medicine and biology. Green chemistry approach to nanoparticle synthesis offers several advantages, including process scaling, economic feasibility, and a safe technique to make nanoparticles. Bioreduced AgNPs can be employed as a therapeutic agent to treat a variety of human ailments. After deeply studying and reviewing different research studies, it was evaluated that the natural nanoparticles have the potential to be effective in the treatment of bacterial and fungal infections.
The impact of evaluation and qualification criteria on Iraqi electromechanical power plants in construction contracts
Authors: Noori Hamza Hamza , Rasheed Sawsan
Published: July 2022

The Ministry of Electricity (MoE) is one of Iraq’s most significant sectoral ministries. Despite massive amount invested in power generation, the country is plagued by power outages for more than three decades. One of the most common sources of the problem and significant impact on the waste of public funds in contractual processes. The Ministry of Planning issued regulations and procedures to facilitate the implementation of power plants by applying the sectorial standard bidding documents (SSBD) of design, supply, and installation of the electromechanical project to support MoE by developing economic projects that lead to raising Iraqi electricity generation field. The research evaluates the government evaluation procedures applied in SSBD and their impact on Iraqi power plant contracts. The study’s principal data gathering approaches via interviews with consultants resulted in a structured questionnaire that includes 25 criteria delivered to MoE’s senior staff. One hundred respondents out of 120. The relative importance index was applied to rank and match respondent consensus on the relevance of the 25 factors. This article’s primary conclusion is weak evaluation of SSBD criteria and inadequate bid evaluations, resulting in an ineffective procurement system, and the results aim to encourage MoE’s decision-makers to optimize the criteria.
Tanshinone IIA reverses oxaliplatin resistance in colorectal cancer through microRNA-30b-5p/AVEN axis
Authors: Ge Tingrui , Zhang Yonggang
Published: July 2022

This research aims to explore the role of Tanshinone IIA (Tan IIA) and microRNA (miR)-30b-5p in chemoresistance of colorectal cancer (CRC). The expression levels of miR-30b-5p and apoptosis and caspase activation inhibitor (AVEN) was detected by reverse transcription-quantitative polymerase chain reaction assay. The cell proliferation and apoptosis were examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry assays. The target relationship between miR-30b-5p and AVEN was confirmed by Dual-luciferase reporter assay. Transwell assay was performed to assess CRC cells’ metastasis. Western blot was carried out to measure the apoptosis-related protein. The results showed that miR-30b-5p was lowly expressed in oxaliplatin-resistance CRC cells SW480 (SW480/R) compared to SW480 cells. Overexpression of miR-30b-5p significantly suppressed the malignant biological behaviors of SW480/R cells and significantly promoted the sensitivity of SW480/R cells to oxaliplatin by down-regulated AVEN expression. Besides, Tan IIA treatment upregulated miR-30b-5p expression in SW480/R cells. Moreover, miR-30b-5p upregulation strengthened the promoting effect of Tan IIA on the sensitivity of SW480/R cells to oxaliplatin. In conclusion, Tan IIA and miR-30b-5p could reverse oxaliplatin resistance of CRC cells and may thus be potential treatment strategies for treating patients with CRC.

Objectives

This study aimed to evaluate the effect size of each parameter used in the first trimester Down syndrome (DS) risk analyses by using multiple regression analysis techniques.

Methods

This data mining study included data of 44,260 pregnant women screened at the Acibadem Labmed laboratories from 2010 to 2019. In this study, risk was calculated using the PRISCA software on the basis of nuchal translucency (NT), crown-rump length measurement, in vitro fertilization application, diabetes mellitus, Down syndrome story, smoking, maternal age, and the level of maternal serum biochemistry markers including pregnancy-associated plasma protein-A (PAPP-A) and free beta-human chorionic gonadotropin (hCGβ).

Results

Forty-four thousand two hundred sixty risk analysis patients result data were re-investigate, and 851 (1.93%) risk analysis results were found as positive. PAPP-A 747 (CI%, 476–1,170) times, NT value 512 (CI%, 343–764) times, DS story 21 times (CI%, 6.7–63.2) and hCGβ value 7.01 (CI%, 6.31–7.79) times affect the combined first-trimester risk analysis results.

Conclusions

We have suggested that those accurate PAPP-A levels and NT levels evaluation are the most critical point of combined risk analysis and that the risk of free hCGβ levels after PAPP-A is essential as a biochemical test.

Sea ice growth and decay are critical processes in the Arctic climate system, but comprehensive observations are very sparse. We analyzed data from 23 sea ice mass balance buoys (IMBs) deployed during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition in 2019–2020 to investigate the seasonality and timing of sea ice thermodynamic mass balance in the Arctic Transpolar Drift. The data reveal four stages of the ice season: (I) onset of ice basal freezing, mid-October to November; (II) rapid ice growth, December–March; (III) slow ice growth, April–May; and (IV) melting, June onward. Ice basal growth ranged from 0.64 to 1.38 m at a rate of 0.004–0.006 m d–1, depending mainly on initial ice thickness. Compared to a buoy deployed close to the MOSAiC setup site in September 2012, total ice growth was about twice as high, due to the relatively thin initial ice thickness at the MOSAiC sites. Ice growth from the top, caused by surface flooding and subsequent snow-ice formation, was observed at two sites and likely linked to dynamic processes. Snow reached a maximum depth of 0.25 ± 0.08 m by May 2, 2020, and had melted completely by June 25, 2020. The relatively early onset of ice basal melt on June 7 (±10 d), 2019, can be partly attributed to the unusually rapid advection of the MOSAiC floes towards Fram Strait. The oceanic heat flux, calculated based on the heat balance at the ice bottom, was 2.8 ± 1.1 W m–2 in December–April, and increased gradually from May onward, reaching 10.0 ± 2.6 W m–2 by mid-June 2020. Subsequently, under-ice melt ponds formed at most sites in connection with increasing ice permeability. Our analysis provides crucial information on the Arctic sea ice mass balance for future studies related to MOSAiC and beyond.
“Our Lady’s Immaculate Heart Will Prevail”
Authors: Hoang Tuan
Published: July 2022

Marian devotionalism was the most popular faith practice among twentieth-century Vietnamese Catholics. Yet its contents were not uniform but reflected shifting realities of church history and Vietnamese history. In particular, the period 1940–1975 witnessed a monumental movement that associated Marianism with anticommunist nationalism among many Vietnamese Catholics. This development came from a combination of several interlocking factors, some global and some local. The development indeed reflects a pattern of interactions between the global and the local in the history of Vietnamese Marianism. It further illustrates the agency of Vietnamese Catholics, who welcomed ideas and beliefs from the global church yet also actively shaped them to further the destiny of their national church.

Published: July 2022

Recent work analytically investigates the heat transfer characteristics of a three fluid heat exchanger used for domestic heating applications with respect to different design parameters, i.e. flow rate, inlet temperature, tube diameter, coil diameter, and coil pitch. The present and previous results are compared with the literature. Overall agreement among these results are observed with little variation. Afterwards, the present temperature data was verified with prior experimental data and little deviation observed in these results vary from -4.28 % to +6.68 % and -6.17% to +5.92% in parallel and counter flow configuration, respectively. It is ensued that the coil side Nusselt number increases with the rise in coil side fluid flow rate and inlet temperature, coil outside fluid inlet temperature and coil diameter respectively. The increment in coil side flow rate and inlet temperature are identified as the major contributors, with 297% and 39.5% contributions. Similarly, growth in coil outside Nusselt number is observed with the rise in coil side fluid inlet temperature and flow rate, coil outside fluid flow rate and inlet temperature, and coil pitch respectively. The coil pitch and flow rate at the coil outside are identified as major contributors with 36% and 28.5% contribution repsectively. Distinct correlations for heat transfer in the present HEx are proposed for coil inside and outside fluid flow in a turbulent flow regime. The developed correlations results are compared with the present result, and reasonable agreement is observed within the data range of +13% to -14% and +10% to -11% for coil inside and outside Nusselt number, respectively.
Process Parameters Optimisation and Numerical Simulation of Laser Beam Welded Butt Joints of Maraging Steel

Published: July 2022

Maraging steels are ultra-high strength iron nickel-based alloys which are used in military applications like rocket motor casings, missiles, and ship hulls. In the current work, maraging steels of 250 grade butt joints with 2 mm thickness are welded by using Nd:YAG laser. The experiments were designed and conducted using the L16 orthogonal array. Various welding parameters selected for the current work are laser power, welding speed, and focal position, whereas tensile strength, hardness and depth of penetration were considered as the output responses. The influence of process variables on weld bead morphology was analysed experimentally. The microstructure, mechanical characteristics and numerical analysis of the optimum joint were also investigated. Analysis of variance (ANOVA) was used to determine the effect of different variables on tensile strength and depth of penetration. According to the results, laser power and welding speed are essential factors for tensile strength. The depth of penetration is strongly influenced by welding speed, focal position, and laser power. In order to predict the weld bead, finite element analysis was performed on ABAQUS 3D finite element software. The results reveal that finite element simulation and experimental observations are matched.

An online voting system is an election system that manages the election process. This is a medium for the voters to cast their votes. It is also being used to calculate the votes collected from the voters to choose the representative for their own faculty. A typical voting system is based on a single attempt for each candidate being voted. The voting does not reflect the criteria implies to the characteristic of the candidate that going to be the student leader. To be a student leader, the student should fulfil the requirement such as good academic results, interpersonal skills with society, involving in activities of university and etc. Although the current voting system is able to maximize the participation of the voters, the voters may blindly vote the ballots casually due to they do not know the details of the candidates and the result is low quality and low public’s trust in the selected candidate. In this study, the aim is to develop an interactive online voting system that have ranking feature with MCDM method which allow online voting system to collect high-quality results from the voters. The Multiple Criteria Decision Making (MCDM) method is used in the voting system while choosing the candidate. MCDM can let the voters make decision making or selecting the candidate based on the criteria that suit the position. The study starts with the literature study on implementing MCDM for a voting system. Then, a survey will be made to get the users’ views on the with and without implementation of the MCDM method in an online voting system. The expected result of the study is to investigate the current implementation of MCDM as a tool for decision making, then identify the possibility of adopting MCDM for the online voting system while choosing the representative for faculty students’ society. As a conclusion from the survey from the users’ views, it shown that most of the users thinks that the system with the implementation with MCDM method is less time consuming and able to produce high quality result compare to the current online voting system. Most of the respondents also stated that they are more preferring to use the online voting system with MCDM method in the future.

Published: July 2022

The use of biodiesel in blended mode is holding a more significant potential in making diesel engines environment-friendly. Published work specifies an optimum blend of biodiesel with diesel oil as B20. Further, the literature indicates that preheating biodiesel in the temperature range between 60°C to 120°C helps to increase the blend percentage up to 50%.In this experiment an effort has been made to use 100% Waste cooking oil methyl ester (WCME) biodieselby employing two stage heating in the temperature range from 100°C to 250°C. In the first stage the heater is immersed in fuel tank that heats biodiesel up to 70oC that lowers the viscosity and eases pumping. In the second syage, an electric preheater is installed along the high-pressure fuel line for achieving higher temperatures. The performance and emission results are encouraging and indicates that Brake Specific Fuel Consumption decreases by 5.4%, Brake Thermal Efficiency increases by 6.15%, Carbon Monoxide (CO) and unburnt hydrocarbon (HC) emissions fall by 38% and 25.5%, respectively. NOx has increased marginally by 4-6%.

This study investigates the potential of a simple and Hybrid artificial neural network (ANN) to predict dense alumina's critical thermal shock temperature (ΔTc). The predictive models have been constructed using two ANNS models (M1, M2). In the first model (M1), elaboration, physical and mechanical parameters have been exploited to build three ANNs, namely generalized linear regression (M1-GLRNN), extreme learning machine (M1-ELM), and radial basis function (M1-RBFNN). The second model (M2) has been built by the three models mentioned above incorporated by the Shannon Entropy (SE) method. To compare the performance of all the developed models, coefficient of correlation (R), root mean square error (RMSE), mean absolute percentage error (MAPE), and Nash-Sutcliffe efficiency coefficient (NSE) have been considered. It is found that M2-RBFNN model with (RMSE = 4.3526, MAPE= 0.3406, NSE = 0.9921, and R= 0.9960) had superiority to the M1-RBFNN model (RMSE = 4.7030, MAPE= 0.3003, NSE = 0.9908, and R = 0.9954). More importantly, the contribution of the present work is that prediction of ΔTc has been performed through the developed hybrid model (M2-RBFNN), which reduces the number of inputs from six to only four inputs and offers high accuracy for all the studied variables.
Dusza ludzka stworzona na obraz i podobieństwo Boga. Refleksja na podstawie Kazań 80, 81 oraz 82 z serii Kazań o Pieśni nad Pieśniami świętego Bernarda z Clairvaux
Authors:   Uniwersytet Papieski Jana Pawła II w Krakowie, Chojnacki Marek
Published: July 2022

The article presents reflections based mainly on three sermons: 80, 81, 82 from the series Super Cantica by Saint Bernard of Clairvaux, a representative of the so-called monastic theology and the twelfth century Renaissance. The Abbot is intrigued by the problem of sin in the life of the Christian community and the evident tendency to commit sins by baptized faithful, endowed with free will. The soul, created in the image and likeness of God, is subject to the fall of original sin. This issue is addressed in two works: De gratia et libero arbitrio and Sermons 80, 81, and 82 on the Song of Songs. The issues are interpreted differently in these works, although the medieval author pointed out that they were: “different (...), but not opposing”.The main source for the article is the critical edition of the saint’s works: Sancti Bernardi opera omnia, vol. I-VIII, Recensuerunt J. Leclercq, H. Rochais, C.H Talbot, Romae 1957-1977. In the Sermons on the Song of Songs, the thought is expressed that man, after original sin, loses integrity, that is, nobility as simplicity (rectitudo), while greatness (magnitudo) remains. It can be said that the soul retains greatness, that is, among other things, immortality, and its vocation to eternal life with God. The likeness to God is indestructible, but it can be darkened, or covered with a “cloak”. The effect of original sin is a soul that tends to the low and earthly things, but that is constantly looking for something that leads to God. The will becomes the slave of sin. The common thought of the two doctrines is expressed in the greatness of man created in the image of God (or the Word); a greatness that can be in the freedom or ability that man has for God. There is also a similarity (similitudo), which in the first doctrine is destroyed but recover able; in the second doctrine it is darkened by a form of “covering dissimilarity”. Only The Lord, by His grace, leads man on the way back to the Father.

For centuries man has been intrigued by the phenomenon of the existence of the world, especially the world’s age: whether it has a beginning or perhaps is eternal. Augustine and Thomas Aquinas share a consistent view that the fact of the creation of the world is truth in principle, going beyond the natural way of understanding of the human intellect, and that is why it was necessary for humans to learn about this truth through the revelation of God. Both Augustine and Thomas are very cautious in interpreting the nature of the act of creation, claiming that it stands behind this mystery of the incomprehensible will and power of God. They both also present the compatibility of the creation of the world by God out of nothing. The description of the creation of the world in the doctrine of Thomas is more systematic in terms of metaphysics than in the description of Augustine because of the distinction between necessary being and continent being, in which the essence and existence do not identify, which has influenced Thomas in his interpretation of the nature of the act of creation.

For many cloud service providers, virtual machines remain the basic technology for computing virtualization. Virtual machines are used both to host application software and to implement container virtualization. Widespread use of virtual machines develops specialized software to determine the impact of model parameters on the quality of the consolidation process, which will prevent experimental research in production to evaluate new cloud data center resource management strategies. In recent years, there were many approaches in literature that offers various sets of software tools and frameworks for modeling data center processes, providing a platform and the necessary building blocks to optimize the process of consolidation of virtual machines. Models and software tools for modeling data center resource management processes are usually not exhaustive and solve a specific problem or management task. The specialized simulation software presented in the paper allows to investigate different control modes of virtual machines dynamic consolidation, provides a wide range of logging and debugging information using text and MS Excel files, such as performance indicators and workload diagrams, and allows to determine the optimal model parameters for various modes of data center operation, minimizing the number of active physical servers and reducing the number of SLA violations.

A software is developed for inventory automation based on Android using the Firebase database in the Java programming language. The appendix uses a system of reading barcodes and QR-codes, which provide the addition of goods to the warehouse with all the details of the selected product and information on all stocks in the warehouse with their price, category, name and code goods. Implemented authorization of system users using the open FirebaseAuth standard. Creating a single service for authorization and registration allows to make the system scalable. The system implements the search for goods by code, as well as viewing stocks in the warehouse with automatic price calculation. The main service of the database is a cloud database of the NoSQL class, which allows storing and synchronizing data between several clients, there is an API for data encryption. In addition, the database remains available only in the application to avoid unauthorized access and editing. While development, it was decided to make an automated control system on the Android OS device, because industrial digitalization (precisely because of the mass introduction of smart devices) requires mobility and accelerated processing of stocks at various stages of turnover. Testing of the developed software is carried out.

Published: July 2022

O presente artigo tem como objetivo identificar como ocorre o desenvolvimento das competências docentes no ensino superior. A coleta de dados foi realizada por meio de uma pesquisa descritiva, aplicada por intermédio da plataforma virtual do “Google Forms”. A amostra foi composta por 199 docentes que atuam em universidades públicas e privadas no estado Santa Catarina, sendo coletada por acessibilidade e conveniência. Por meio da técnica estatística de regressão múltipla, evidenciou-se que o suporte institucional se apresentou como preditor exclusivamente para o desenvolvimento de competências gerais e a autoaprendizagem demonstrou-se como preditora apenas para o desenvolvimento de competências de ensino, pesquisa e competências gerais. Constatou-se ainda a necessidade de ampliar o desenvolvimento das competências de extensão e de gestão nas instituições de ensino, por meio do suporte institucional ou da autoaprendizagem.
The nocturnal body of democracies
Authors: Regatieri Ricardo Pagliuso , Santos Patrícia da Silva
Published: July 2022

This article engages with the contemporary debate about de-democratization and authoritarianism, arguing that these phenomena cannot be properly understood without discussing the roots of modern democracy in colonial capitalism. In the first half of the twentieth century, some voices in social theory drew attention to possibilities for regression inscribed in Western civilization. Nonetheless, the prevailing tone of the postwar era was one of optimism regarding democracy, democratization and democratic consolidation. It was only more recently that discussions about regressive tendencies were placed on the table once again. Though we consider that these analyses have helped to shed light on such tendencies, we argue that they overlook the fact that the bright side of democracy – proudly exhibited in the core countries – was achieved at the cost of a concealed side, which has now returned to haunt the world.

Authors: Morales-Pon Harley R.
Published: July 2022

El artículo aborda la manera en que la Revolución Popular Sandinista y el proceso de institucionalización del neoliberalismo, a través de las acciones llevadas a cabo por sus máximos representantes y gestores, influyeron en la reconfiguración de la estructura y correlación de fuerzas en el campo del trabajo urbano en Nicaragua en el período de 1980-2002; también trata la manera en que las luchas materiales y simbólicas desplegadas en el seno de dicho campo social se fueron cristalizando. Finaliza con una breve reflexión en torno al proceso que dio lugar a la sindicalización de las personas trabajadoras por cuenta propia en la Confederación de Trabajadores por Cuenta Propia.
The cracow school. Arising of the national style in polish architecture of the interwar period
Authors: Wiśniewski Michał
Published: July 2022

In the 1920s, the architects belonging to the so-called Cracow School faced the challenge of creating public buildings to suit the needs of the re-born state administration as well as the challenge of defining the iconography and symbolism with which it could be identified. The School’s strong position soon after Poland regained independence was due to the fact that Cracow was the most important Polish artistic center at the time. From 1901, operated there the Association of Polish Applied Art, which through various publications, contests, and exhibitions, looked for a Polish national style based on Polish vernacular art and European modernism. The artists belonging to the Association, and later to the Cracow Workshops, best suited the artistic needs of the re-born state. Apart from being commissioned to carry out various prestigious projects, many of them also reached top positions at Art Academies, which had fundamental significance for the development of the Polish arts. The history of the Cracow School represents an appropriate background for a vast analysis of the relations between the arts and politics and also economic and social factors in Central Europe during the interwar period.
