Authors: Wang Baoe , Zhang Rihong , Li Yiyong , Lian Xiaoming 
Published: February 2022

Abstract
The vortex cavitation technology shows a great development potential for antibiotic wastewater treatment. We have designed a novel swirling vortex cavitator for tetracycline degradation in aqueous solution. By Computational Fluid Dynamics (CFD) simulation using ANSYS CFX flow field calculation software, it was found that the vortex cavitator could form a low-pressure area far lower than the saturated vapor pressure at experimental temperature, resulting in generation of obvious vortex cavitation effect, which also proved by the concentration of hydroxyl radical of 4.58 μmol/L measured by methylene blue method. Moreover, the tetracycline degradation process may be mainly caused by the oxidation of hydroxyl radicals. The batch experiments results showed when the degradation time was 30 min, the vortex cavitator had a good degradation ability of tetracycline in pH range of 5.0–9.0. The degradation efficiency of 2.0 mg/L tetracycline solution was 76.45% within 50 min at pH 7.0. The possible intermediate products of tetracycline were determined by HPLC-MS Spectrometry. A series of reactions including hydroxylation, decarbonylation and C–N bond cleavage, ring-opening, and removing two methyl groups in the carbon atom ring, occur during the degradation.

Published: February 2022

Abstract
Aluminiumalloy (AA2014) based metal matrix composites were produced by spray atomization and co-deposition. The mass median diameter and mass flow rate of SiC were varied between 6 and 58 μm and between 10 and 30 wt.% of the melt flow rate, respectively. Microstructures of deposits and overspray powder particles were examined. Porosity and SiC content were measured at different positions in the preform. The fraction of SiC particulates incorporated in the preform varies between 4 and 11 vol.%, which is caused by the low compaction efficiency lying within the range of 30 to 50% of injected secondary particulates. Porosity is observed to increase with increase in deposited SiC content. Optical microscopy shows a uniform distribution of particles in the microstructure. Microstructural examination of overspray powder particles shows that the basic reason for the incorporation of smaller particles is the collision between reinforcement particles and the liquid droplets during flight. The results are presented and discussed in light of process parameters used.
Derivation and consistency of the partial functions of a ternary system involving interaction coefficients
Authors: Reddy Ramana G. , Reddy Singareddy R. 
Published: February 2022

Abstract
Margules equations are used to express the thermodynamics of a ternary system containing one solvent and two solutes in the vicinity of solvent, in terms of first order interaction coefficients of binary and ternary systems. Considering just the first order Margules coefficients, the resultant excess Gibbs energy function was convergent and the derived logarithmic activity coefficients of solvent and solutes were thermodynamically consistent. In the present study Margules equations are modified to get consistent equations. Partial functions of a ternary system are deduced using these modified equations via the excess Gibbs energy function. Derived partial functions are thermodynamically consistent and also deduced results are the same as those obtained using Maclaurin infinite series. Using the activity coefficient expressions of solvent and solutes, the activity coefficients of solvent and solute are calculated in Ni– Cr–Fe and Fe–Ti –C ternary systems, which are in excellent agreement with the experimental data.

AbstractRahman and Shpilrain proposed a Diffie–Hellman style key exchange based on a semidirect product ofn×nn\times n-matrices over a finite field. We show that, using public information, an adversary can recover the agreed upon secret key by solving a system ofn2{n}^{2}linear equations.
G-Elo: generalization of the Elo algorithm by modeling the discretized margin of victory
Authors: Szczecinski Leszek 
Published: February 2022

AbstractIn this work we develop a new algorithm for rating of teams (or players) in one-on-one games by exploiting the observed difference of the game-points (such as goals), also known as a margin of victory (MOV). Our objective is to obtain the Elo-style algorithm whose operation is simple to implement and to understand intuitively. This is done in three steps: first, we define the probabilistic model between the teams’ skills and the discretized MOV variable: this generalizes the model underpinning the Elo algorithm, where the MOV variable is discretized into three categories (win/loss/draw). Second, with the formal probabilistic model at hand, the optimization required by the maximum likelihood rule is implemented via stochastic gradient; this yields simple online equations for the rating updates which are identical in their general form to those characteristic of the Elo algorithm: the main difference lies in the way the scores and the expected scores are defined. Third, we propose a simple method to estimate the coefficients of the model, and thus define the operation of the algorithm; it is done in a closed form using the historical data so the algorithm is tailored to the sport of interest and the coefficients defining its operation are determined in entirely transparent manner. The alternative, optimization-based strategy to find the coefficients is also presented. We show numerical examples based on the results of the association football of the English Premier League and the American football of the National Football League.
Einfluss der Stadtstruktur auf das raumbezogene Sicherheitsgefühl
Authors: Berthold Mathias , Meyer Maike , Dahlen Lena 
Published: February 2022

ZusammenfassungDas subjektive Sicherheitsgefühl der Bevölkerung und die objektive Sicherheitslage gehen häufig auseinander. Für eine effektive Kriminalprävention sollten beide Ebenen berücksichtigt werden. Im Hinblick auf eine zielgerichtete städtebauliche Kriminalprävention wurden mögliche Zusammenhänge zwischen dem subjektiven Sicherheitsgefühl in der Wohngegend und Merkmalen der physischen sowie sozialen Stadtstruktur analysiert. Die Daten zum Sicherheitsgefühl stammen aus einer Bevölkerungsbefragung des Landeskriminalamtes Nordrhein-Westfalen. Die Daten zur Stadtstruktur wurden über die infas360 GmbH bezogen. Mit den getrennten Datenquellen sollte überprüft werden, inwieweit sich objektiv vorliegende Daten zur Erklärung des Sicherheitsgefühls und in der Konsequenz auch für zielgerichtete Kriminalprävention nutzen lassen. Im Ergebnis zeigten sich lediglich geringe Zusammenhänge. Weder die Variablen der physischen Stadtstruktur, noch die Variablen der sozialen Stadtstruktur konnten wesentlich zur Erklärung des subjektiven Sicherheitsgefühls auf der individuellen Ebene beitragen, obgleich die Richtung der Zusammenhänge den theoretischen Annahmen entsprochen hat. Eine Mehrebenanalyse zeigte, dass die objektiven Daten eher auf der Ebene der Postleitzahlbereiche und nicht auf der individuellen Ebene wirken. Letztendlich wird angenommen, dass die räumliche Betrachtungsgröße auf Postleitzahlbereichen zum einen und die methodische Trennung zwischen dem subjektiv erhobenen Sicherheitsgefühl und den objektiv vorliegenden Daten der Stadtstruktur zum anderen dazu führten, dass lediglich geringe Zusammenhänge festgestellt werden konnten. Bei der Verwendung soziostruktureller Daten sollte somit stets die räumliche Bezugsgröße berücksichtigt werden, auf der sie Wirkung entfalten.

Published: February 2022

Abstract
The degree to which COVID-19 severity influences the development of acute cerebrovascular events (ACVE) is unknown. Therefore, we aimed to describe the prevalence and risk of ACVE in patients with severe and nonsevere COVID-19. We systematically reviewed MEDLINE, EMBASE, Web of Science, and Scopus and identified observational and interventional studies of patients with COVID-19 allocated by respiratory severity that reported ACVE development. Case reports/series were excluded. The main outcome assessed was the pooled rate of ACVE in patients with severe and nonsevere COVID-19. To determine the risk of ACVE development by COVID-19 severity, a meta-analysis was performed. PROSPERO registration number: CRD42020178905. About 19 of 5758 identified studies were analyzed. From 11,886 COVID-19 patients analyzed, 421 had at least one ACVE [3.6%, 95% confidence interval (CI) 2.904–4.179]. Severe COVID-19 increased the risk of ACVE (odds ratio 1.96, 95% CI 1.22–3.15; P = 0.005; I
2 = 64%), specifically hemorrhagic stroke (4.12, 2.0–8.53; P = 0.001; I
2 = 0%). There was no difference in the risk of developing ischemic stroke between patients with severe and nonsevere COVID-19 (1.53, 0.87–2.7; P = 0.14; I
2 = 52%). From the patients who developed any ACVE, those with severe COVID-19 had a greater mortality risk than those with nonsevere COVID-19 (3.85, 1.08–13.70; P = 0.04; I
2 = 0%). The main limitations of our study were the heterogeneity found in the main meta-analysis studies and in their reported definition for COVID-19 severity. In conclusion, our findings provide evidence that COVID-19 respiratory severity could lead to ACVE development that increases mortality. The effect of COVID-19 management in ACVE needs to be evaluated.

“É melhor escrever sobre risos que sobre lágrimas…”
Authors: Ponzio Luciano 
Published: February 2022

A experiência do riso parece destinada a desaparecer quase completamente no mundo de nosso tempo? Ou podemos considerar o riso como uma das linguagens humanas mais poderosas mais potentes no plano criativo, configurando-se uma estética do riso como uma lógica de derrubada, de ousadia abdução, inferencial e de regeneração do mundo? Certamente, a comunicação linguística não é feita apenas de palavras. E o riso alegre e profanador que subverte as hierarquias e as regras sérias da ideologia dominante é um riso aberto, intersubjetivo, liberatório e libertador, e o papel que a alteridade nele desempenha torna o riso impossível de ser definido em uma significação e em uma designação precisas denotando, ao invés disso, uma ineliminável ambiguidade e polissemia ​​de um signo muito particular determinado não apenas por sua resistência, mas também como uma das formas mais eficazes de resistência ao monologismo dominante.

Abstract
Fruit of Ziziphus jujuba Mill. are used as functional foods for centuries due to their rich content and bioactivities. Although in vitro antioxidant and hypoglycaemic activity of jujube fruit were investigated previously, the bioavailability phenomenon has been disregarded so far. For this study, 80% ethanol extract of Ziziphus jujuba fruit (ZJE) was investigated for its in vitro hypoglycaemic and antioxidant potentials, before and after the interaction with simulated human digestion. DPPH scavenging activity, FRAP, CUPRAC, and TOAC assays were used for this purpose. Moreover, inhibition potentials of α-amylase and α-glucosidase enzymes and advanced glycation end products (AGE) were examined for the hypoglycaemic effect. Results indicated that ZJE showed significant antioxidant and dose dependent enzyme and AGE inhibition activity. Nonetheless, subsequent to simulated human digestion in vitro bioactivities of ZJE were significantly lowered for bioavailable fraction (IN). Protocatechuic acid (PA) (major phenolic compound of the fruit) contents of the extract and fractions were measured via HPTLC for more accurate understanding of the effects of human digestion and bioavailability profile.

Abstract
The journalist is usually synonymous with mainstream media such as television, radio, newspapers or magazines. Film is one of the mass media that is able to contain elements of journalism, as well as other mainstream media. One of the films with the theme of journalism is the Spotlight film.
The purpose of this study is to find out whether the Spotlight film is able to represent elements of journalism. Just as representing the main obligations of journalism is truth, journalism's first loyalty to citizens and so on.
The choice of analysis in this study used Charles Sanders Pierce's semiotic analysis. Pierce's analysis is known as Triangel meaning which consists of Signs, objects and interpreters.
The results showed that spotlight films were able to represent elements of journalism, almost every scene contained an element of journalism, such as a scene where one of the figures suggested writing their telephone number so that citizens could call directly to their office. In addition, in this study, a new development was based on Pierce's thinking, Pierce's theory to analyze a sign using three elements, namely the Sign object and interpretant while the results developed from Pierce's theory became four elements namely sign, object, context and interpretant.

The COVID-19 Vaccines: A Description of Adverse Events or Reactions Reported in Kansas
Authors: Mills Kale , Tri Anna , Nilsen Kari 
Published: February 2022

Introduction. Coronavirus disease 2019 (COVID-19) is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and has spread rapidly throughout the world since its discovery in 2019. Three vaccines (Pfizer-BioNTech, Moderna/NIAID/BARDA, and Johnson & Johnson’s Janssen) have been developed for use in the U.S. to aid in the fight against this virus, but have been scrutinized intensely for their efficacy and safety. It is important to understand and interpret the adverse events or reactions (AERs) associated with these vaccines in an objective and analytical manner. The goal of this descriptive study was to provide a resource outlining AERs associated with the three available vaccines in Kansas.
Methods. Reports were obtained from the Vaccine Adverse Event Reporting System (VAERS), representing AERs observed in Kansas from December 11th, 2020, to May 13th, 2021. All data were screened and coded, and descriptive statistics were used to describe AERs based on vaccine manufacturer, age, gender, and reported deaths.
Results. Only 0.068% of COVID-19 vaccines doses given were associated with an AER. The most common AERs were fatigue/tiredness, tingling/itching, fever, hives, and muscle/joint paint. Only 0.002% of reports to VAERS were associated with a death. The majority of reports were by females (78.8%) and those aged 30 to 39 (20.6%).
Conclusions. No reported AERs were unexpected compared to national data, and no VAERs report provided a causal relationship between vaccine administration and death. Vaccines are, and will continue to be, essential tools to fight COVID-19. Providing a resource of potential AERs could aid in individual decisions to receive a vaccine and may help in the control of COVID-19.
