Authors: Chidaraboyina Swathi , Nesaraj A. Samson
Published: June 2021

In this work, a simple facile preparation of Ce1-xAlxO2-δ (where x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5)
nanoparticles by chemical synthesis route is reported. In the preparation, appropriate quantities of
metal nitrate salts were dissolved in water alongwith required amount of sodium hydroxide as
precipitant. The resultant precipitate mixture [Ce(OH)3 + Al(OH)3] was washed with water, filtered,
dried and heat treated to get the phase pure Al doped CeO2 nanoparticles. The synthesized oxide
materials were characterized by XRD, FTIR, particle size analysis, SEM and EDAX to understand
their structural, functional and particle properties. The XRD patterns revealed the presence of cubic
(FCC) crystalline structure in the samples. The presence of Al-O and Ce-O stretching mode of vibration
was confirmed by FTIR analysis. The particle size of the materials was found in the range of 117.23 to
257.06 nm. Presence of nano and micron sized grains was noticed by SEM photographs. EDAX
confirmed the presence of appropriate atomic weight percentage of elements in the samples. The results
suggested that the prepared Al doped ceria nanoparticles can be useful in several applications.

Published: June 2021

The extensive biological potential of thiazolidin-4-one and 1,3,4-thiadiazole moieties, the novel string
of 5-(arylidene)-2-(5-methyl-1,3,4-thiadiazol-2-ylimino)thiazolidin-4-one has been synthesized and
characterized. The synthesized derivatives were screened for antimicrobial potential using serial tube
dilution method. The results showed that all the synthesized compounds have significant biological
activity against the microorganisms being tested. The antimicrobial activity of the compounds TA2,
TA3, TA4, TA9, TA10 and TA20 against the tested microbial strains was promising. Compound TA4
(2-((5-methyl-1,3,4-thiadiazol-2-yl)imino)-5-(4-nitrobenzylidene)- thiazolidin-4-one) and TA2
(5-(4-chlorobenzylidene)-2-((5-methyl-1,3,4-thiadiazol-2-yl)imino)thiazolidin-4-one) showed
promising antimicrobial activity against microbial strains. Compound TA9
(5-(4-(benzyloxy)benzylidene)-2-((5-methyl-1,3,4-thiadiazol-2-yl)imino)thiazolidin-4-one) was found
to be the most effective towards B. subtilis. Compound TA10 (5-(3,4-dimethoxybenzylidene)-2-((5-
methyl-1,3,4-thiadiazol-2-yl)imino)thiazolidin-4-one) was discovered to be the most potent against
the Gram-negative bacteria. Compounds TA3 (5-(4-bromobenzylidene)-2-((5-methyl-1,3,4-thiadiazol-
2-yl)imino)thiazolidin-4-one) and TA20 (5-(2-bromobenzylidene)-2-((5-methyl-1,3,4-thiadiazol-2-
yl)imino)thiazolidin-4-one) were the most effective compounds against the fungal strain.

Authors: Kristianto D. , Ibadurrohman M. , Setiadi  , Slamet
Published: June 2021

The study aimed to get the optimum antibacterial properties on fabric. CuO-doped TiO2 composite
was synthesized by photo assisted deposition method. The amount of CuO loading varied (1.5%, 3%
and 6%) in the total weight of composite to obtain the optimum effect of CuO in photodisinfection
Escherichia coli. The 3% CuO/TiO2 possessed the optimum antibacterial activity with 92% of E. coli
were disinfected within 2 h. This phenomenon was supported by the UV-Vis DRS results, which
implied the addition of CuO could act as a dopant and an electron trapper in reducing the band-gap
energy to 2.97 eV in 3% CuO/TiO2. Fourier-transform infrared spectroscopy (FTIR) analysis showed
the Ti-O-Ti and Ti-O-Si bands, which confirmed TiO2 attach on fabric.

Authors: Hadi Al-Kaabi Falah Kareem , Al-Duri Bushra , Kings Iain
Published: June 2021

The destruction of 3-methylpyridine by supercritical water oxidation (SCWO) using propylene glycol
(PG) and isopropyl alcohol (IPA) as co-fuels in a plug flow reactor was carried out. Hydrogen peroxide
was the oxygen source. All the experiments were carried out at 25 MPa and a range of temperatures
from 425-525 ºC. The residence times range from 6 s to 14 s. Results were presented in terms of total
organic carbon (TOC) as a function of time with various process parameters. The findings support the
positive effect that propylene glycol has on the destruction of 3-methylpyridine, where TOC removal
is ≥ 97.5% at 525 ºC and 14 s. The maximum TOC removal efficiency is 93% at 425 ºC, 14 s, and the
[propylene glycol]/[3-methylpyridine]o ratio of 3. The removal efficiency of nitrogen in the presence
of propylene glycol reaches 89% at 525 ºC and 10 s. The oxidant ratio also has a positive effect on the
removal of TOC in the three systems. Addition of propylene glycol causes a significant development
in the ratio at 425 ºC, more so than when isopropyl alcohol was added. This is due to two hydroxyl
groups in propylene glycol oxidation that enhance the reaction by generating various free radicals.
Effect of Cross-Linked Agents on the Morphology of Keratin/Egg White Blend Particles
Authors: Tanisood S. , Srihanam P.
Published: June 2021

The effect of cross-linked agents e.g. acetic acid, polyethylene glycol diglycidyl ether (PEGDE) and
genipin on the morphology of keratin/egg white (KT/EW) blend particle formation by emulsification
solvent diffusion method was observed. The concentration of blending solution and spinning rate
(rpm) for obtaining desired particles were also studied. SEM images indicated that the shapes and
sizes of KT/EW blend particles varied by the types of cross-linked agents and conditions used. A high
concentration of acetic acid and PEGDE interrupted the rheology of blend solution, which interfered
the particle formation as well as enhancing the protein denatured. In contrast, the high content of
genipin did not affect the morphological shape and size of the particles. A high rotation per minute
(rpm) rate was suitable for blend particle formation mixed acetic acid and PEGDE whilst suitable rpm
rate for genipin was slower than 2 types of cross-linker. The morphological shape and surfaces of the
KT/EW blend particles affected by the types and conditions used. These results obtained the informative
data for the development of keratin/egg white blend particles to apply in specific fields such as drug-delivery
system.
Fluorescence Recognition of Al(III) Ions by a New Chemosensor Based
E-4-((1-(10H-Phenothiazin-2-yl)ethylidene)amino)-N-(pyrimindin-2-yl)benzenesulfonamide
Authors: Vijayakumar P. , Arockia Doss M. , Negar S. Nargis , Renganathan R.
Published: June 2021

A novel Schiff base derivative E-4-((1-(10H-phenothiazin-2-yl) ethylidene)amino)-N-(pyrimindin-2-
yl)benzenesulfonamide (BT) was synthesized and characterized by 1H & 13C NMR, FT-IR and mass
spectrometry. Compound BT acts as a detector for Al3+ in ethanol/water HEPES buffer solution (5
mM, pH 7.4, v/v 1:4) at room temperature. The fluorescence intensity observed at 516 nm was increased
due to Al3+ ion present with a fluorescence response “turn-on” process, when excited at 290 nm. This
shows compound BT is coordinated to Al3+ ion through the NH group and C=NH of the Schiff base
blocking the photoinduced transfer (PET) and chelation induced enhanced fluorescence (CHEF) process,
to increase the fluorescence intensity of BT. The detection limit of BT was in a micro-molar range for
Al3+ ion, confirming high selectivity and sensitivity of BT. The BT-Al3+ ion binding mode and the
recognition mechanism of chemosensor were explored by EDTA titration, Job’s plot, Mass and FT-IR
analysis. The theoretical support was established by DFT calculations.

Published: June 2021

Single crystals of a organic compound, (Z)-4-((4-fluorophenyl)amino)pent-3-en-2-one (4FPA) were grown
by the slow evaporation technique and characterized by X-ray diffraction and FT-IR spectra. The normal
mode frequencies, intensities and the corresponding vibrational assignments were calculated using
the GAUSSIAN 09W set of quantum chemistry codes at the DFT/B3LYP levels of theory using the
6-31+G(d,p) basis set. The Fourier transform infrared spectrum was obtained for the title molecule at
room temperature. Reactivity features were determined based on global descriptors, electron density
mapping and Fukui analysis to reveal the electrophilic and nucleophilic coordination of them. The
thermodynamic and intramolecular interactions were also investigated. The non-covalent interaction
mapped by reduced density gradient method reveals possible methyl (CH3) influence on the ring and
NH groups with their reactivity and non-linear optical properties of 4FPA were found by first-order
hyperpolarizability.
Binding Constants Determination of Ofloxacin and Ornidazole Enantiomers with
Sulfated β-Cyclodextrin as Single Ligand by Capillary Electrophoresis using
Three Different Linear Plotting Methods
Authors: Al Azzam Khaldun M.
Published: June 2021

The aim of this research is to use capillary electrophoresis to establish/determine the binding constants
for ofloxacin and ornidazole enantiomers with the negatively charged chiral selector
sulfated-β-cyclodextrin (S-β-CD). Using electrophoretic mobility values of ofloxacin and ornidazole
enantiomers at various concentrations of S-β-CD used in the context of background electrolyte (BGE),
binding constants were calculated using three separate linearization plots, namely double-reciprocal,
X-reciprocal and Y-reciprocal. The R-ofloxacin enantiomer-S-β-CD complex had the highest inclusion
affinity of the ofloxacin and ornidazole enantiomers, which matched with previously reported estimation.
Every enantiomer-S-β-CD complex’s binding constants, as well as thermodynamic binding parameters,
were calculated at different temperatures. The host-guest binding constants using double reciprocal fit
showed greater linearity (R2 > 0.99) at all temperature ranges measured (15-30 ºC) as compared to the
other two fit approaches. The thermodynamic complexation parameters were found to be dependent
on the temperature of the enantiomers, as seen by the linear van’t Hoff (15-30 ºC) plot.

Published: June 2021

Soft and conductive interfaces are valuable in wearable electronics as they are capable for integration
of diverse classes of electronic and sensor technologies directly with living body which can be used as
health monitoring systems. In present work, we explore the development of multi-walled carbon
nanotube-ethylene vinyl acetate nanocomposite (MWCNT-EVA) film and their properties. Oxidation
of MWCNT is known to improve their dispersion properties and increase the electrical conductivity
of MWCNT-polymer nanocomposites. Thus, pristine MWCNTs (p-MWCNTs) and functionalized
MWCNTs (f-MWCNTs) were further used as conductive filler to construct p-MWCNT-EVA and
f-MWCNT-EVA nanocomposite films. The films were characterized by Fourier-transform infrared
spectroscopy, scanning electron microscopy, energy dispersive X-ray analysis and electrochemical
technique. The results indicated that the chemical oxidation of p-MWCNT generates carboxylic function
at the p-MWCNT surface important for sensor fabrication. The concentration of carboxylic functional
group in f-MWCNT higher than in nanocomposites. The f-MWCNT-EVA nanocomposite film electrode
surface show much higher conductivitythan p-MWCNT-EVAnanocomposite film. Thus, the soft and
flexible f-MWCNT-EVA nanocomposite films are effective for the development of electrochemical
platform for biosensor fabrication in wearable applications.
Coaches attitudes about returning to play in youth and varsity sports post- COVID-19
Authors: Deutsch Joe , Waldera Roman
Published: June 2021

BACKGROUND: One industry affected by the COVID-19 mandated social distancing policies is sport. In the wake of pressures to return to some normalcy, sport leagues have begun a return to play, many of which include regulations additional to the typical athlete and fan experience. Youth, Middle School, and High School sport leagues are of specific interest in America given the currently inconclusive national plan for returning to face-to-face instruction of students at schools. PURPOSE: The current goal is to identify the perceptions and experiences of current sport professionals throughout the country regarding a return to play. METHODS: The participants of this study were 181 Youth and High School Sport Coaches of various sports. The sample contained males (n = 123) and females (n = 58). The age of respondents ranged from 20 or more years of age. A return to play questionnaire was created and used to collect data for this study. The survey consisted of 12 yes or no questions regarding a return to play during the pandemic, with an opportunity for an open-ended explanation for each. Statistical methods employed to conduct data analysis included frequencies to determine percentages. A crosstabs analysis and Pearson Chi-Square tests of association were utilized to identify statistical significance within the variables. FINDING: No statistically significant association was found at the p ≤ .05 level between age or years of coaching experience and any response to a yes/no question. Percentages for high school coaches who responded "Yes" to each question are presented. Due to the wide variety of responses in these open-ended explanations, statistical expressions were not conducted, and an inclusive list of explanations for each question is provided. CONCLUSION: While the research result is unclear, the information obtained from coaches in the current study presents a small illustration of the current perceptions of athletic leaders in this region regarding the return to play of youth sport coaches and their respective schools' policies.
Entrepreneurial Bricolage and New Product Development Performance in New Ventures: The Contingent Effects of Founding Team Involvement
Authors: Wang Xinchun , Yu Xiaoyu , Meng Xiaotong
Published: June 2021

New product development (NPD) performance is a key determinant of a new venture’s success. However, compared with established firms, new ventures often suffer from resource constraints when developing new products. Entrepreneurial bricolage is reported in the literature as an alternative strategic option that enables managers to overcome resource constraints when developing new products. However, because new ventures are often founded by an entrepreneurial team, the effectiveness and efficiency of using bricolage to improve NPD performance might be contingent on how the founding team plays its roles in this process. Using data from 323 new ventures in China, we find support for the critical role of entrepreneurial bricolage in improving NPD success under resource constraints. More importantly, our results reveal that the bricolage strategy is more likely to benefit a venture when the founding team is composed of members with diverse functional backgrounds and is not heavily involved in strategic decision-making.

Published: June 2021

Dye is a common pollutant present in many chemical industrial waste water. Advanced oxidation processes are widely used for dye degradation. In this study, the degradation of trypan blue dye was examined by Fenton process. Neutralized red mud catalyst was used as a source of ferrous ion for Fenton’s process. The dye degradation performance has been analyzed by using circulating fluidized-bed reactor. The influence of some key parameters such as pH, initial dye concentration, catalyst dosage and hydrogen peroxide concentration on the degradation of dye has been investigated. All the experiments were performed for 90 min. The initial dye concentration was taken as 1.56 × 10−5 and 2.60 × 10−5 mol L−1 and the amount of catalyst was varied from 0.5 to 0.7 gm/L. The hydrogen peroxide was taken in the ratio of 1:20 with the catalyst. The effect of pH was studied in the varying range from 3–5. It was found that the more the acidic pH, more will be the rate of degradation. The increase in pH results in the lower degradation rate. As the amount of catalyst was increased, the degradation rate got increased. The optimized results were obtained at pH 3, catalyst dosage of 0.7 gm/L and dye concentration of 1.56 × 10−5 mol L−1. Subsequently, the reaction kinetics of Fluidized-bed reactor was also studied.

Published: June 2021

Nano-opto-electro-mechanical systems (NOEMS), considered as new platforms to study electronic and mechanical freedoms in the field of nanophotonics, have gained rapid progress in recent years. NOEMS offer exciting opportunities to manipulate information carriers using optical, electrical, and mechanical degrees of freedom, where the flow of light, dynamics of electrons, and mechanical vibration modes can be explored in both classical and quantum domains. By exploiting NOEMS concepts and technologies, high speed and low-power consumption switches, high-efficiency microwave-optical conversion devices, and multiple quantum information processing functions can be implemented through on-chip integration. This review will introduce the principles of NOEMS, summarize the recent developments, and important achievements, and give a prospect for the further applications and developments in this field.
Heritage Artefacts in the COVID-19 Era: The Aura and Authenticity of 3D Models
Authors: Cardozo Thiago Minete , Papadopoulos Costas
Published: June 2021

Museums have been increasingly investing in their digital presence. This became more pressing during the COVID-19 pandemic since heritage institutions had, on the one hand, to temporarily close their doors to visitors while, on the other, find ways to communicate their collections to the public. Virtual tours, revamped websites, and 3D models of cultural artefacts were only a few of the means that museums devised to create alternative ways of digital engagement and counteract the physical and social distancing measures. Although 3D models and collections provide novel ways to interact, visualise, and comprehend the materiality and sensoriality of physical objects, their mediation in digital forms misses essential elements that contribute to (virtual) visitor/user experience. This article explores three-dimensional digitisations of museum artefacts, particularly problematising their aura and authenticity in comparison to their physical counterparts. Building on several studies that have problematised these two concepts, this article establishes an exploratory framework aimed at evaluating the experience of aura and authenticity in 3D digitisations. This exploration allowed us to conclude that even though some aspects of aura and authenticity are intrinsically related to the physicality and materiality of the original, 3D models can still manifest aura and authenticity, as long as a series of parameters, including multimodal contextualisation, interactivity, and affective experiences are facilitated.
A Theoretical Framework for Informal 3D Rendered Analysis of the RomanLarariumfrom Apollonia-Arsuf
Authors: Schoueri Kelly Gillikin , Teixeira-Bastos Marcio
Published: June 2021

Digital reconstruction and visualization of archaeological sites are beneficial not only for public edification and admiration, but they can also significantly contribute to the site interpretation process. By going beyond basic modeling scenarios, one can apply 3D analyses for accurately testing visibility and lighting parameters, among other aspects. Based on the results of these tests, further insights can be extrapolated about the lived experience of culturally specific ancient peoples. The case of a Roman “villa” at Apollonia-Arsuf in Israel presents the opportunity to apply these informal techniques to a household shrine, or niche-stylelararium, found within the building in order to ascertain sightline visibility based on the architectural plan and visual impact as a result of artificial illumination from ceramic lamps. This paper also considers how photorealistic visualizations aid in phenomenological areas of research through sensory archaeology and sense of place, which in turn encourages reflection on the political, social, and religious meanings of the built environment. When we combine the power and diverse applications of 3D visualization technology with decades of research about Roman architecture, culture, religion, and social norms, the result is a step closer to recreating archaeological remnants and, in turn, understanding the ancient experience.
Evaluation of the catalytic activity of graphene oxide and zinc oxide nanoparticles on the electrochemical sensing of T1R2-Rebaudioside A complex supported by in silico methods
Authors: Bisetty Krishna , Kanchi Suvardhan , Hloma Phathisanani
Published: June 2021

Herein, we report on the performance of graphene oxide (GOx) and zinc oxide nanoparticles (ZnONPs) on a platinum (Pt) electrode, immobilized with the human T1R2 sweet taste receptor subunit for the detection of rebaudioside A (Reb-A). The characterization studies performed in this work confirmed the thin-layered structure of GOx and the polydispersed nature of ZnONPs. The elucidation of the mass loss observed by TGA demonstrates the stability of GOx. The cyclic voltammetry results for Pt/GOx revealed good catalytic activity over Pt/ZnONPs for adsorption of the T1R2-Reb-A complex. In addition, a series of computational modelling studies were carried out to better understand the surface adsorption phenomena of GOx and ZnONPs to mimic the layer-by-layer electrode modification strategies independently. The strongest interaction energy observed (−573 kcal mol−1) for the direct interaction of ZnONPs onto the Pt electrode surface, demonstrates a stronger adsorption in contrast to the GOx modified Pt electrode (−23 kcal mol−1). However, the overall results for the layered-nanocomposite revealed that the GOx (−256 kcal mol−1) were more strongly adsorbed in contrast to ZnONPs (−231 kcal mol−1) for the detection of the T1R2-ReB-A complex, demonstrating the reliability of our GOx electrode functionalization strategy. The results of this study can potentially be used to improve the design of rapid Reb-A sensors for the food and beverage industry.

Published: June 2021

Accurate, precise, and rapid analytical monitoring of various nuclear materials is essential for the smooth functioning of nuclear reactors. Ion chromatography (IC) has emerged as an effective analytical tool for simultaneous detection of different ions in a wide range of materials used in the nuclear industry. The major advantages over other techniques include superior selectivity and sensitivity for detection of anions and cations, wide dynamic range, and speciation studies of ions. This article provides an overview of different ion chromatographic methodologies developed for the analyses of various nuclear materials such as fuel, control rods, moderator, coolant, and process streams. Comparison of various analytical aspects of IC over the other routine techniques reveals the ease and multidimensional capability of the technique. An insight is given to the modern variations in the field such as coupling of IC with other techniques for the characterization of nuclear matrices, implementation of capillary IC in terms of miniaturization, and so on. The information presented herein will serve as a very useful resource for investigators in the field of characterization of nuclear materials.

Could after the division of administration in 364 an emperor issue a law for the entire empire?
Authors: Sirks A.J.B.
Published: June 2021

The question whether the administrative division of the Roman empire in 364 or 395 implied also a divided legislation, i.e. that each part could or did legislate only for itself, has been extensively debated. To all appearances the emperors issued laws jointly, and likewise the prefects issued edicts jointly. Yet it is possible to deduce from the few relevant texts that these manifestations of unity were merely ideological: in practice each part could only issue laws for itself, and laws of the other part had to be confirmed expressly in order to gain validity. This implies that inclusion in the Theodosian Code of laws of each part did not make them universally valid.

Zwischen Infektionsschutz und Schutz des Erblasserwillens: Das sogenannte testamentum tempore pestis conditum in C.6,23,8 (290)
Authors: Willems Constantin
Published: June 2021

Protecting the testator’s last will in times of a contagious disease: The so-called testamentum tempore pestis conditum in C. 6,23,8 (290). This paper revisits C. 6,23,8, a constitution by emperor Diocletian from 290 CE on the subject of alleviated testamentary formalities in times of a contagious disease. It is argued that the imperial rescript is to be understood against the background of an epidemic raging at that time, maybe to be identified as the smallpocks. With this constitution, it is further argued, the emperor clarifies that a former piece of legislation, not passed down to us, exempts the testamentary witnesses in such times from assembling as a group with the person of the testator, while there is no exemption from the general requirement of calling in the accustomed number of witnesses. Thus, the emperor takes account of the testator’s need to stipulate his last will in times of crisis while at the same time having an eye to the witnesses’ fear of contagion.
Inconsistent Use of Resistance Exercise Names in Research Articles: A Brief Note
Authors: Nuzzo James L.
Published: June 2021

Nuzzo, JL. Inconsistent use of resistance exercise names in research articles: a brief note. J Strength Cond Res 35(12): 3518–3520, 2021—Academic fields require standard nomenclature to communicate concepts effectively. Previous research has documented resistance training exercises are named inconsistently. This inconsistent use has been observed among fitness professionals and within resistance training textbooks. The purpose of the current note was to explore inconsistent use of resistance training exercise names in scientific articles. Keyword searches were performed in PubMed to identify articles that referred to 4 different resistance training exercises. The search was limited to titles and abstracts of articles published between 1960 and 2020. For exercise 1, “shoulder press,” “overhead press,” and “military press” were searched. For exercise 2, “arm curl,” “bicep curl,” and “biceps curl” were searched. For exercise 3, “hamstring curl,” “leg curl,” and “knee curl” were searched. For exercise 4, “calf raise” and “heel raise” were searched. For exercise 1, 114 articles included “shoulder press” in their title or abstract, 42 articles included “overhead press,” and 45 articles included “military press.” For exercise 2, 244 articles included “arm curl,” 37 articles included “bicep curl,” and 177 articles included “biceps curl.” For exercise 3, 24 articles included “hamstring curl,” 159 articles included “leg curl,” and 7 articles included “knee curl.” For exercise 4, 68 articles included “calf raise” and 154 articles included “heel raise.” The results are evidence of inconsistent use of resistance training exercise names in scientific articles. A possible solution to inconsistent use of exercise names in research articles, educational texts, and clinical practice is a system that includes a standard exercise naming pattern and guidelines for communicating exercise names.
The Gap in Prescribing Stroke Prevention Therapies in Postoperative Atrial Fibrillation After Isolated Coronary Artery Bypass Grafting Surgery

Background: Postoperative atrial fibrillation (POAF) commonly occurs after coronary artery bypass graft (CABG) surgery. Patients with POAF are at higher risk of stroke and mortality. The use of oral anticoagulation (OAC) in POAF remains inconsistent, and the care gap is unknown. Objective: We sought to evaluate rate of adherence and factors associated with OAC use in POAF patients after isolated CABG.
Methods: In this study, all patients who had an isolated CABG between April 1, 2019 and March 30, 2020, at Health Sciences North, Sudbury retrospectively were evaluated. We identified all patients who developed POAF and captured the use of OAC. Multivariable logistic regression models were used to identify predictors of OAC prescription.
Results: In total, 339 CABG patients between April 1, 2019 and March 30, 2020, were identified; 86 patients developed POAF. No patients had major perioperative bleeding. All POAF patients had an indication for OAC therapies based on CHADS 65 score. However, only 17 (19.8%) patients with POAF had OAC prescription at the time of hospital discharge.  Baseline characteristics were similar between those with or without OAC. In multivariable analysis, the use of dual antiplatelet therapy was associated with a decreased use of OAC therapy in POAF (OR 0.037 (95% CI 0.005, 0.29), P = .002). Moreover, in comparison to surgeon A, surgeon B was associated with a decreased use of OAC therapy, whereas surgeon C was associated with an increased use of OAC therapy in POAF (OR 0.15 (95% CI 0.03, 0.83), P = .03 and OR 6.49 (95% CI 1.21, 34.82), P = .03, respectively). None of the CHADS 65 elements, including age, hypertension, stroke, diabetes mellitus or congestive heart failure, correlated with the use of OAC.
Key findings: Eighty percent of patients who developed POAF after isolated CABG failed to receive stroke prevention therapies. The use of dual antiplatelet therapy and individual surgeons’ preference were associated with the use of OAC therapy among POAF.
Conclusions: This data set suggests that approximately only 1 in 5 patients with POAF after isolated CABG got prescribed OAC.

Published: June 2021

The purpose of this study was to examine the influence of the interaction of political connections with Good Corporate Gavernance (GCG) on tax avoidance. The samples in this study were all manufacturing companies on the Indonesia Stock Exchange (BEI). The method of determining the sample using purposive sampling in accordance with predetermined criteria and obtained a sample of 279. The analysis technique is multiple linear regression. The test results of multiple linear regression analysis show that GCG has no effect on tax avoidance, while the interaction of political connections with Good Corporate Gavernance (GCG) has a significant effect on tax avoidance, so Good Corporate Gavernance (GCG) is proxied by the board of commissioners and audit committee purely moderating while the board of directors is a pseudo variable or quasi moderating. Tax avoidance is an effort to ease the tax burden by not violating the law. Tax avoidance is a complex and unique issue because it does not violate the law (legal) but is unwanted by the government because it reduces state revenue.

One of the problems faced by Indonesia is the low level of the tax ratio. In order to increase state revenue from the tax sector, efforts should be made to increase voluntary tax compliance. This study aims to examine the effect of religiosity and gender on tax compliance. The method used is quantitative “mix methods” using regression analysis and descriptive analysis of the questionnaire obtained through “convenience sampling methods”. The results showed that religiosity and gender had a positive effect on tax compliance. The higher the level of religiosity, the level of taxpayer compliance will also increase. This research contributes to providing input to tax authorities to increase tax awareness through outreach in religious communities by involving women.

Hypervirulent Klebsiella pneumoniae (hvKP) strains are associated with vigorous clinical presentation and relapses. Initially reported from Asia, these variants have spread globally and become an emerging agent of significant health threat. This study was carried out to identify hvKP strains in a previously uninvestigated region and to evaluate the impact of commonly-employed phenotypic and genotypic markers as diagnostic assays. A total of 111 blood culture isolates, collected at a tertiary care center was investigated. The hvKP strains were sought by a string test and the amplification of partial magA, rmpA, iucA and peg344. All products were characterized via sequencing. Evidence for hvKP was observed in 10.8% via iucA amplification (7.2%), string test (2.7%) and magA amplification (0.9%). Specific products were not produced by assays targeting rmpA and peg344 genes. Antibiotic susceptibility patterns compatible with possible extensive or pan-antimicrobial resistance was noted in 66.7% of the hvKP candidate strains. Capsule type in the magA positive strain was characterized as K5. We have detected hvKP in low prevalence at a region with no prior documentation. Targetting the aerobactin gene via iucA amplification provided the most accurate detection in this setting. The epidemiology of hvKP in Anatolia requires elucidation for effective control and management.
European and Slovak Examples of Pop-up Theaters •
Authors: Boháčová Kristína , Schleicher Alexander
Published: June 2021

A large group of emerging cultural spaces abroad and in Slovakia has the adjective independent. In this context, this means that they were not established by public institution and are looking for sustainable forms of funding themselves, operating on grants and volunteering system. The limited amount of funding also determined the architecture that covers such cultural centers. Historic ruins, neglected public spaces, abandoned industrial buildings are common factors that appear throughout Europe. Is there a difference between Slovak alternative and its foreign counterparts, or is it a global phenomenon with identical characteristics? And can it be established at all based on such a small sample as the independent cultural and theater centers are?

A kulturális terek nagyobb csoportja külföldön és Szlovákiában is független jelzővel jelenik meg. Ebben az összefüggésben ez azt jelenti, hogy nem közintézmény hozta létre őket, maguk keresik a finanszírozás fenntartható formáit, támogatásokból és önkéntesekkel működnek. A korlátozott összegű finanszírozás meghatározza az ilyen kulturális központok építészetét is. A történeti romok, az elhanyagolt közterületek, az elhagyott ipari épületek Európa-szerte gyakran jelennek meg helyszíneikként. Van-e különbség a szlovák alternatív és a külföldi gyakorlat között, vagy ez globális jelenség azonos jellemzőkkel? És egyáltalán ez kiderülhet-e a független kulturális és színházi központok egy ilyen kis mintája alapján?
The effect of 8 weeks moderate-intensity continuous training on central hemodynamics and VO2max in non-athlete male
Authors: Mahdiabadi Javad
Published: June 2021

Background and Study Aim. Aerobic exercise improves fitness and quality of life and decreases mortality rate. Existence study determined the central hemodynamic adaptation after 8 weeks moderate-intensity continuous countryside jogging in non-athlete male.

Material and Methods. Twenty-four untrained healthy male students (aged 20-22 years) volunteered and randomly divided into two groups: continuous training (CTG; n=12) and control (CG; n=12). Training program was countryside jogging for 45 min at 65-70% of Maximum Heart Rate (MHR), 3 days/week for 8-weeks performed. The CG group remained sedentary during the study period. Maximal oxygen consumption (VO2max) obtained using the step-test. Standard medical method impedance cardiograph was performed for hemodynamic parameters, during resting and after step-test conditions, before and after the study period.

Results. Using t-test, after eight weeks: the resting heart rate (HR) in CTG group significantly decreased (P≤0.05). The systolic blood pressure (SBP) in CTG group decreased significantly at rest and after workload (P≤0.05). The diastolic blood pressure (DBP) did not change in both groups (P>0.05). The stroke volume (SV) increased significantly in CTG group at rest and after workload (P≤0.05).  The cardiac output (CO) did not change in both groups (P>0.05). The cardiac output (CO) did not change in both groups (P>0.05). The VO2max absolute and relative increased significantly in CTG group (P≤0.05). Significant difference between groups in SBP, SV, SVR and VO2max (absolute and relative) (P≤0.05).

Conclusions. 8 weeks moderate-intensity continuous countryside jogging can improve the cardiac function and VO2max in selected healthy male. The regular exercise of aerobic with moderate intensity causes positive developments in systolic and diastolic blood pressures.
