Authors: Soares Igor Alves Noberto , Silva Nedir Monteiro da
Published: April 2021

RESUMO: o presente trabalho perquiriu a aplicabilidade da visita íntima nos Centros Socioeducativos de Internação do Estado de Minas Gerais, a partir da experiência do Centro Socioeducativo São Cosme de Teófilo Otoni (Brasil), em contexto sistêmico que considere a efetividade dos direitos dos adolescentes. Para tanto, a partir análise de documental e de revisão bibliográfica, o objetivo concentrou-se em entender como os agentes estatais tratam as previsões trazidas pelo ordenamento jurídico brasileiro sobre os direitos sexuais dos adolescentes em cumprimento de medida socioeducativa de internação. Nesse sentido, foram analisadas as diretrizes normativas relacionados à Secretaria de Estado de Justiça e Segurança Pública, competente para a tutela da estrutura destinada às medidas socioeducativas. Ao final da pesquisa, concluiu-se que o direito à visita íntima do adolescente ainda é obstado em observância aos destoantes aspectos morais, e, não raras vezes, somente viabilizado a partir de intervenção judicial.

Forming Analysis of Bulge Formed Joints Based on Adaptive Finite Element Method
Authors: ZHAI Jinjin , SUN Yuantao , ZHANG Qing , QIN Xianrong
Published: April 2021

Metal bulk forming is widely used because of its own advantages. In order to improve the production efficiency and reduce the cost, numerical simulation is often used to analyze the volume forming process. Because of the large deformation and non-linearity of the forming process, the finite element method (FEM) has the problem of element distortion, which will affect the accuracy and even lead to the failure of the analysis process. In this paper, an adaptive finite element method (AFEM) is proposed to solve this problem. Firstly, the finite element model is established, and grids are roughly divided. After the analysis, according to the error calculation model, the area with large error is determined by the standard deviation of nominal strain energy of nodes. Then, the grids are refined by dichotomy method, and the calculation is continued, repeating this step until the error meets the requirement. Finally, the numerical analysis of the forging process of the bulge formed joint is taken as an example to prove the accuracy of the proposed method.
The Comparative Study of Pretend Plays Between 5 - 7 Years Old High-functioning Autistic Children and Their Normal Peers with Child-initiated Pretend Play Assessment
Authors: Mirzakhany Navid , Farzinfar Mansure , Dabiri Golchin Minoo
Published: April 2021

Background: Autism is one of the prevalent disorders in childhood. Children with autism have difficulties in different life skills and their daily activities. Pretend plays are essential in improving these skills, but the patterns of playing are impaired in this group. Objectives: The present study was designed to compare pretend plays between high-functioning autistic children and typical peers. Methods: The research is the result of a cross-sectional study. Two groups of children with high-functioning autism and typical peers in the age range of 5 - 7 years were studied. Each group consisted of 87 participants who were selected by convenience sampling. Each participant was assessed by the Child-Initiated Pretend Play assessment (ChIPPA) test. The results were analyzed using descriptive statistics and an independent t-test. Results: Data analysis and comparison of scores between the two groups of children showed a significant difference in the mean scores. The average percentage score of the number of object substitutions (NOS) and the elaborate pretend play actions (PEPA) in children with autism were lower than typical peers (P < 0.001). In other words, children with autism were less able to organize play and pretend. But the number of imitated actions (NIA) scores in children with autism was higher than their counterparts (P < 0.001). That is, children with autism relied more on examiner-playing patterns. Conclusions: The significant difference in scores between children with autism and typical peers showed significantly lower pretend skills in children with autism. According to pretend play basics on academic skills, language, and having a flexible mind, and with the attention to the same problems in children with autism, pretend play can be in greater attention to be improved among these groups.

A vueltas con el Primer Testimonio (Io. 1,15-18) de Juan el Bautista y su identidad en el Commentarius in Iohannem de Orígenes de Alejandría
Authors: Bueno Ávila Antonio ,   Instituto Patristico Augustinianum
Published: April 2021

This article analyses an old issue regarding the identity of John the Baptist in the Commentary on the Gospel of John by Origen of Alexandria in response to the Gnostic Heracleon and some enigmatic anonymous adversaries. Taking as a starting point the two hypotheses existing nowadays about this topic, a new approach is proposed through which it is shown that both hypotheses are not mutually exclusive. The present work has been structured into two large sections. The context where this debate emerges is presented in the first part. This context refers to the continuity or discontinuity between the Old and New Testaments. The second part is focused on the identity of John the Baptist adopting the point view related to the impossibility of identifying the disciple with no specific character, also revealed in the first section.
Centurio, tribunus, princeps en Hilario de Poitiers, in Matth. 7, 3-5: texto bíblico y exégesis a la luz de gnósticos y Orígenes
Authors: Cano Gómez Guillermo J. ,   Instituto Patristico Augustinianum
Published: April 2021

In this paper we shall examine a few texts by authors who predate Hilary in order to investigate a possible exegetical tradition or interpretative current that could include several gnostic groups cited by Irenaeus of Lyons (II c.), to Origen (III c.) and saint Hilary of Poitiers (IV c.). However, one of the interpretations that Origen presents in his Commentary on saint John is the same interpretation that Hilary gives, but it is more developed. Certainly, Hilary and Origen comment two different Gospels, but both comment homologous scenes; Hilary comments Mt. 8:5-13 and Origen, Io. 4:46-54. In addition, we believe some testimonies in Hilary’s commentary can reveal the influence of Origen’s commentary on Hilary/s. One of these testimonies could be the explanation of the strange reading transmitted by Hilary who calls tribunus to the centurio of the Gospel.
Between Angels and Beasts
Authors: Genghini Maria Giulia ,   Instituto Patristico Augustinianum
Published: April 2021

This paper explores Augustine’s ideal of just society, as developed in books XII, XIV and XIX of the City of God, and its rehabilitation of the notion of civitas peregrina. Bringing to maturity the classical notion of community (according to Aristotle and Cicero’s definitions), Augustine investigates how, in the Christian view, the different kinds of societies, which arise on earth, are dependent on the acceptance or refusal of the relation between man and his transcendental origin. This connection between metaphysics and history allows for an alternative reading of the City of God, by which man’s spiritual life and its public and social dimensions escape dichotomist views and the confinement to a purely philosophical or religious discourse.

Music as Environment: Biological and Ecological Constraints on Coping with the Sounds
Authors: Reybrouck Mark
Published: April 2021

This paper deals with musical sense-making in a real-time listening situation. Revolving around the ecological conception of organism-environment interaction, it elaborates on the interactions between the listener as an organism and the music as environment. The listener, in this view, can be described in terms of coping behavior that is shaped by biological and ecological constraints. Relying on the seminal work by von Uexküll and Gibson in the fields of biosemiotics and ecology, with a special emphasis on the concepts of functional tone and affordance, listeners are defined as organisms that actively seek for information by carrying out physical and epistemic interactions on the sonic environment. As such, they construct an inner model of the sonic world as the sum total of subjective meanings that are assigned to those elements that receive semantic weight. By stressing the role of functional significance and interactions, this approach is on a continuum with the biosemiotic claims that music knowledge must be generated as a tool for adaptation to the sonic world. Musical sense-making, in this view, relies on several levels of processing, going from low-level reactivity to higher-level processing by the brain.
William S. Burroughs and The Wild Boys Against the Language Virus: A Biosemiotic Guerilla
Authors: Patoine Pierre-Louis
Published: April 2021

This article proposes a biosemiotic reading of William S. Burroughs’ The Wild Boys– A Book of the Dead (1971), showing how literature, by cutting up narrative structures and syntactical units, can fight the language virus’ configuring of human vitality, just like bacteria uses CRISPR-Cas9 to cut-up the DNA code-chains of threatening viruses. We will see that, supported by the shared biosemiosic nature of literary texts and biological forms, this parallel extends beyond the metaphorical to reinsert literature within the realm of living processes.
Culture, Politics and Biology from a Biosemiotic Perspective
Authors: Wheeler Wendy
Published: April 2021

In this article I shall offer some considerations on the implications for political thought (broadly conceived) of the relatively new interdiscipline of biosemiotics. The semiological analysis associated with the work of Ferdinand de Saussure is a now familiar part of cultural and political analysis, but its weakness has always been, first, its narrow focus on human uses of language alone, and, second, its related inability to talk about biology. Given the extent to which human mind and behaviour are an effect of biological systems, this is a considerable omission. Joining culture and nature as part of the evolution of semiotic layers in recursive biocybernetic systems, biosemiotics insists there is an ontological and practical link between both that should be part of scientifically informed political theory and policies.
Biosémiose vs. Robosémiose
Authors: Walsh Matthews Stéphanie
Published: April 2021

Toute quête identitaire nous conduit forcément à un questionnement sur nos origines. Qu’est-ce qui nous distingue de nos proches? Quels sont nos premiers traits humains apomorphes? Quelle est la première instance de notre humanité? Plus généralement, en tant qu’êtres vivants, de quelle manière sommes-nous propulsés vers l’humanisation? La trajectoire des hominides nous parait ici centrale. Si, à l’évidence, l’ensemble des sciences humaines s’y intéressent, la sémiotique intervient principalement pour questionner notre phéno-réalité dans sa dimension biosémiotique (voire aussi paléosémiotique, archéosémiotique, etc.) Notre travail consiste ici à relever les éléments propres à cette trajectoire. Pourra-t-on mieux comprendre nos traits singuliers en étudiant leur inimitabilité? La robotique humanoïde, toujours incapable malgré ses prétentions de reproduire l’être humain, pourrait-elle nous aider à y voir plus clair? En opposant biosémiose et robosémiose, cet article propose de faire un pas dans ce débat, dont l’enjeu consiste à déceler en nous le trait humain le plus significatif et à saisir comment l’inégalable summum de notre humanité pourrait enfin se dévoiler.
Change in the Turreky’s Balkan policy of Turkey under the rule of the Justice and Development Party: the Davutoğlu effect
Authors: Kolot Burak
Published: April 2021

This article is dedicated to the analysis of Turkey's foreign policy aimed at achieving regional leadership after the Cold War, as well as the changes that took place therein under the rule of the Justice and Development Party) since 2002. The author describes the principles of Turkey's policy in the Balkans under the rule of the Justice and Development Party, which are founded on the doctrine of strategic depth proposed by Ahmet Davutoğlu in 2001, who was appointed Minister of Foreign Affairs in 2009 (until 2014). The following questions arise: are the political priorities and goals outlined in the theory compatible with the Turkey’s foreign policy in the Balkans, which holds an important place in the doctrine; and what is the impact of the neo-Ottoman approach adopted in relation to Muslim communities in the Balkans affect the policy conducted against the non-Muslim communities? Besides the Davutoğlu’s doctrine, the article employs archival documents obtained from the official website of the Ministry of Foreign Affairs of Turkey, as well as publications and books by various Turkish and foreign experts that allow reconstructing the true picture of events. The goal of this work is to comprise a broad picture of Turkey's position on the international arena in the 2000s and foreign policy perception of the Justice and Development party overall. In this regard, analysis is conducted on Turkey’s interests in the Balkans and the policy for achieving them under the rule of the Justice and Development Party.
Inverse regulation of Vibrio cholerae biofilm dispersal by polyamine signals
Authors: Bridges Andrew A , Bassler Bonnie L
Published: April 2021

The global pathogen Vibrio cholerae undergoes cycles of biofilm formation and dispersal in the environment and the human host. Little is understood about biofilm dispersal. Here, we show that MbaA, a periplasmic polyamine sensor, and PotD1, a polyamine importer, regulate V. cholerae biofilm dispersal. Spermidine, a commonly produced polyamine, drives V. cholerae dispersal, whereas norspermidine, an uncommon polyamine produced by vibrios, inhibits dispersal. Spermidine and norspermidine differ by one methylene group. Both polyamines control dispersal via MbaA detection in the periplasm and subsequent signal relay. Our results suggest that dispersal fails in the absence of PotD1 because endogenously produced norspermidine is not reimported, periplasmic norspermidine accumulates, and it stimulates MbaA signaling. These results suggest that V. cholerae uses MbaA to monitor environmental polyamines, blends of which potentially provide information about numbers of ‘self’ and ‘other’. This information is used to dictate whether or not to disperse from biofilms.
Diversity patterns and drivers of soil microbial communities in urban and suburban park soils of Shanghai, China
Authors: Zhang Weiwei , Han Jigang , Wu Haibing , Zhong Qicheng , Liu Wen , He Shanwen , Zhang Lang
Published: April 2021

Background

The rapid expansion of urbanization leads to significant losses of soil ecological functions. Microbes directly participate in key soil processes and play crucial roles in maintaining soil functions. However, we still have a limited understanding of underlying mechanisms shaping microbial communities and the interactions among microbial taxa in park soils.

Methods

In this study, the community variations of bacteria and fungi in urban and suburban park soils were investigated in Shanghai, China. Real-time PCR and high-throughput Illumina sequencing were used to examine the microbial abundance and community composition, respectively.

Results

The results showed that soil molecular biomass and fungal abundance in urban park soils were significantly higher than those in suburban park soils, while no significant difference was observed in the bacterial abundance between urban and suburban park soils. The alpha diversity of soil microbes in urban and suburban park soils was similar to each other, except for Chao1 index of fungal communities. The results of similarity analysis (ANOSIM) revealed remarkable differences in the composition of bacterial and fungal communities between urban and suburban park soils. Specifically, park soils in urban areas were enriched with the phyla Methylomirabilota and Verrucomicrobiota, while the relative abundance of Gemmatimonadota was higher in suburban park soils. Moreover, the fungal class Eurotiomycetes was also enriched in urban park soils. Compared with suburban park soils, nodes and average paths of the bacterial and fungal networks were higher in urban park soils, but the number of module hubs and connectors of the bacterial networks and negative interactions among bacterial taxa were lower. Compared with suburban park soils, Acidobacteriota bacterium and Mortierellomycota fungus played more important roles in the ecological networks of urban park soils. Soil available zinc (Zn), available nitrogen (N), pH, and total potassium (K) significantly affected fungal community composition in park soils in Shanghai. Soil available Zn was also the most important factor affecting the bacterial community composition in this study.

Conclusion

There were significant differences in the soil molecular biomass, fungal abundance, and the community composition and co-occurrence relations of both soil bacterial and fungal communities between urban and suburban park soils. Soil available Zn played an important part in shaping the structures of both the bacterial and fungal communities in park soils in Shanghai.

Published: April 2021

This research was carried out to study the morphological characteristics of Coptodon zillii from Lake Komadugu in Yobe State, Nigeria using morphometric measurements, meristic counts and length-weight relationship. A total of 60 specimens of Coptodon zillii were purchased from the fisher folks at landing site in Lake Komadugu, examined and analyzed for morphometric and meristic characterization. The results revealed that all the morphometric characters of C. zillii in Lake Komadugu varied whereas some meristic characters including mean number of rays on pectoral fin (8.00 ± 0.00), pelvic fin ray (5.00 ± 0.00), anal fin spine (3.00 ± 0.00), pelvic fin spine (1.00 ± 0.00) and number of lateral line (2.00 ± 0.00) were constant. A significant linear relationship was established and represented by the equation: W =0.008SL2.097 (r =0.6410 d.f. = 58) for male, W =0.001SL3.013 (r = 0.9600 d.f. = 58) for female. Mean condition factor which was not significantly different (p>0.05) showed that male C. zillii had 1.80 ± 0.27, female (1.92± 0.26) and pooled sex (1.86 ± 0.25). Findings of this study implies that C. zillii from Lake Komadugu are in good health. In conclusion, these findings are very useful in stock assessment, population dynamics, sustainable management and conservative measures of C. zillii in Lake Komadugu.

Authors: Chebet Hellen , Kinyua Johnson , Kareru Patrick , Gitaari Njiema
Published: April 2021

The consumption of alcoholic drinks have highly risen recently to a situation whereby there is a deficit in the stores, this is due to the higher demand compared to supply. Due to the high prices of most of the industrialized brews, consumers have opted for locally brewed drinks. Although locally manufactured brews are not recognized and certified by law, most are of good quality and with low cost of production. The use of Tithonia diversifolia can be employed to aid in improvement of the rate of production of local and industrialized brews. The main aim of this project was to improve the rate of fermentation of alcoholic beverage using both Tithonia diversifolia leaves extracts and iron II nanoparticles derived from it. It was observed that the plant catalyst reduced the time taken to produce alcohol. Alcohol fermentation rate in presence of yeast and with a tithonia extract as catalyst was measured, Rates of alcohol production was measured by UV VIS at intervals of one hour and deduced from a calibration curve. From the data, the alcohol content was higher in the sample catalyzed by the complexed extract and the one containing extracts as the catalyst as compared to the one without a catalyst. The percentage ethanol was able to be detected by finding absorbances (beer lambert law A = e l c.).

Published: April 2021

Sulal River is a victim of nutrient pollution as it crosses different small-scale tea farms in Bureti Sub County, Kericho County. A study was conducted to evaluate different physicochemical parameters and major chemical fertilizer’s nutrients levels in water and sediments from Sulal River. In order to understand the degree of pollution in the river due to inflow of agricultural chemical fertilizer residue levels from its catchment, the samples were collected in the dry (February 2019) and wet seasons (November 2019). The ten chosen sampling sites stretched a length of 12 Km. Samples were analyzed for pH, dissolved oxygen (DO), total dissolved solids (TDS), electrical conductivity (EC), sediment and water content (WC), nitrate-nitrogen (NO3-N), phosphorous (PO3-P) and potassium (K) using standard methods. Results were analyzed using IBM SPSS 20. The average results during dry and wet seasons in water samples for pH were 6.72±0.05 and 6.38±0.21, DO 6.78±0.59 and 9.58±0.64 mg/L, EC 174±5.02 and 205±20.14 µS /cm, TDS 92±4.59 and 120.70±19.57 mg/L, NO3-N 0.58±0.21 and 1.19±0.22 mg/L, PO3-P 0.00±0.00 and 0.13±0.84 mg/L and K 0.26±0.08 and 0.84±0.19 mg/L respectively. The average results during dry and wet seasons in sediment samples for pH were 6.62±0.20 and 6.75±0.17, EC, 67±6.66 and 52±10.19 µS /cm, WC 16.96±3.95 and 129.84±5.00%, NO3-N 0.70±0.35 and 0.42±0.23 mg/kg, PO3-P 0.49±0.25 and 1.14±0.40 mg/kg and K 1.53±0.45 and 2.86±0.31 mg/kg respectively. The levels of P in water during wet season and in sediments samples in both seasons were however, above the WHO (0.025 mg/L) and KEBS (0.030 mg/L) recommended limit for drinking and domestic use and WASREB (0.005 mg/L) level for the likelihood of eutrophication. Availability of excess phosphorus can accelerate eutrophication. The diversity of cancers has also been associated with drinking water containing phosphorous levels. The water from Sulal River may be used for irrigation purposes but not for drinking and domestic purposes. Significant seasonal variations were observed in all parameters analyzed except NO3-N in sediments. This indicates that rainfall had a great effect on some soil physicochemical properties.
Smart Hydroponic Greenhouse (Sensing, Monitoring and Control) Prototype Based on Arduino and IOT
Authors: Abul-Soud M. A. , Emam M. S. A. , Mohammed Sh. M.
Published: April 2021

Aims: Sensing, monitoring and control the micro-climate measurements and environmental conditions of greenhouse prototype to create a smart hydroponic greenhouse for maximizing the food production as well as minimizing the ecological footprint under the climate change impacts, Coved 19 crisis, and natural resources shortages.

Study Design: Factorial with 3 replicates.

Place and Duration of Study: Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Center, Egypt during 2020.

Methodology: Two systems of hydroponic culture, nutrient film technique (NFT) and deep flow technique (DFT) that cultivated by lettuce plants were established under greenhouse (polycarbonate) prototype (0.8 * 1.2 * 0.6 m) designed with artificial grown light and cooling system. Based on Arduino Mega 2560 that programmed via the Arduino IDE program, different sensors and actuators were used to establishing the smart greenhouse. Internet of things (IoT) via Node MCU ESP 8266 that programmed to transmitted the data every 30 min. to the internet web google platform (Firebase) for presenting the real-time records and hosting the data. Vegetative characteristics; yield parameters and N, P, and K contents of lettuce plants were measured.

Results: the smart greenhouse worked according to the programming of Arduino Mega and Node MCU with high efficiency. Google firebase platform displays the real-time records and hosts about 100 thousand different sensor records during the lettuce season. Decreasing the distance between the lettuce and artificial lightning source led to increasing the intensity of light that had a positive impact on lettuce growth but it wasn't sufficient to give a high quality of lettuce yield under the experiment. NFT system gave higher values of average No. of leaves and fresh weight of lettuce plants than DFT system that presented higher plant length.

Conclusion: Integrated monitoring and control system and IOT provide a wireless sensors network that offered a high capability of accessing huge data anywhere and anytime. Smart management of nutrient solution (TDS, pH, temperature, and level), without smart control, were not useful enough regarding the rapid solution changes and the need for a high response.

Background: As years passes by, the usage of social media has become an important public health issue. It is known that problematic social media use is related with health problems. With this study, it is aimed to determine the social media use of hospital employees, the relation between social media addiction and burnout levels and to determine effective factors.                                                                                                                

Methods: Target population of the cross-sectional study consists of 2627 person between the ages of 18-60 who is working at a university hospital. Minimum sample size was calculated as 321 and reached up to 323 people. Question form, Burnout Scale and Social Media Addiction Adult Form were applied by interviewing the employees face-to-face between the months of March-April 2019.

Results: 80.2% of the participants use social media every day, 63.1% of them use social media mostly at evenings. 94.8% of people mostly connect to social media with their phone. Average time spent daily on social media is 91, 33±87, 89 minutes. Daily social media use is significantly higher in women, university graduates, nurses. There is a significant difference between age groups and between married and never married in terms of average time spent daily on social media. Social media addiction scale score is significantly higher in women, never married persons and in the age group 20-29. Weak correlation was determined between scores of social media addiction scale and burnout levels, and age and time spent on social media.                                                                                                                                        

Conclusions: It is determined that social media usage in hospital employees is higher than Turkey’s average and there is a positive relation between scores of social media addiction scale and burnout levels.

In the present study, we synthesis of Silver nanoparticles using aqueous extract of  Quercus infectoria nuts and Daucus carota subsp sativum leaves. The surface plasma resonance at 417 and 450 nm for Q. infectoria and D. carota respectively confirmed the formation of AgNPs. Scanning Electron Microscopic (SEM) confirmed the spherical shape of the nanoparticles, which had an average size of 67.5 nm and 49.2 nm for Q. infectoria nanoparticles (QAgNPs)and D. carota nanoparticles (DAgNPs). The elemental composition by Energy-Dispersive X-ray analysis of the nanoparticle showed an atomic percentage of silver as 73.64 % and 75.93% for Q. infectoria and D. carota.FT- IR analysis of the plant extracts and synthesized silver nanoparticles showed the presence of various functional groups. The total antioxidant activity of QAgNPs was 81.18% and that of DAgNPs was 73.36%. The QAgNPs and DAgNPs exhibited antibacterial activity against B. subtilis, E. coli and S. aureus. The percentage of cell viability for QAgNPs and DAgNPs assessed using HeLa cells was 21.1% and 6% respectively.
Reliability Analysis of a Home-scale Microgrid Based on a Threshold System
Authors: Hidayat Taufal , Rushdi Ali Muhammad
Published: April 2021

The reliability of a microgrid power system is an important aspect to analyze so as to ascertain that the system can provide electricity reliably over a specified period of time. This paper analyzes a home-scale model of a microgrid system by using the threshold system model (inadvertently labeled as the weighted k-out-of-n:G system model), which is a system whose success is treated as a threshold switching function. To analyze the reliability of the system, we first proved that its success is a coherent threshold function, and then identified possible (non-unique) values for its weights and threshold.  Two methods are employed for this. The first method is called the unity-gap method and the second is called the fair-power method. In the unity-gap method, we utilize certain dominations and symmetries to reduce the number of pertinent inequalities (turned into equations) to be solved. In the fair-power method, the Banzhaf index is calculated to express the weight of each component as its relative power or importance. Finally, a recursive algorithm for computing system reliability is presented. The threshold success function is verified to be shellable, and the non-uniqueness of the set of weights and thresholds is demonstrated to be of no detrimental consequence, as different correct sets of weights and threshold produce equivalent expressions of system reliability.

Glucose oxidase is a subset of oxidoreductase enzymes that catalyzes the transfer of electrons from an oxidant to a reductant. Glucose oxidases use oxygen as an external electron acceptor that releases hydrogen peroxide (H2O2). Glucose oxidase has many applications in commercial processes, including improving the color and taste, increasing the persistence of food materials, removing the glucose from the dried egg, and eliminating the oxygen from different juices and beverages. Moreover, glucose oxidase, along with catalase, is used in glucose testing kits (especially in biosensors) to detect and measure the presence of glucose in industrial and biological solutions (e.g., blood and urine specimens). Hence, glucose oxidase is a valuable enzyme in the industry and medical diagnostics. Therefore, evaluating the structure and function of glucose oxidase is crucial for modifying as well as improving its catalytic properties. Finding different sources of glucose oxidase is an effective way to find the type of enzyme with the desired catalysis. Besides, the recombinant production of glucose oxidase is the best approach to produce sufficient amounts of glucose oxidase for various uses. Accordingly, the study of various aspects of glucose oxidase in biotechnology and bioprocessing is crucial.
Laboratory monitoring approaches for tailings settling and evaluation of flocculant and coagulant treatments

Published: April 2021

X‐ray computer tomography (CT), magnetic resonance imaging (MRI), and nuclear magnetic resonance (NMR) are applied for laboratory monitoring of the settling behaviour in tailings suspensions. It is shown that the developed monitoring techniques are consistent with each other and provide different levels of information from 2D density cross‐sections obtained using X‐ray CT to 1D and bulk water content using MRI and NMR. Analysis of coagulant and flocculant treatments based on obtained measurement information is conducted using linear and nonlinear kinetic modelling approaches. The linear Roberts' kinetic model describes the settling of original tailings suspensions very well, but it is not adequate for the suspensions treated with additives. A modified nonlinear Roberts' model is developed and successfully applied to analyze the suspension with additives. The analysis of combined flocculants and coagulants treatments reveals that flocculants significantly affect the settling rate; however, they decrease the efficiency of settling with respect to the residual water content. Coagulants affect mostly the residual water content in samples, but do not change the settling rate significantly. The trade‐off between concentrations of coagulants and flocculants needs to be achieved for optimal settling treatments.
Corporate social responsibility and financial performance: International evidence of the mediating role of reputation
Authors: Fourati Yosra Makni , Dammak Mariam
Published: April 2021

The aim of this article is to explore both the direct and indirect effect of corporate social responsibility (CSR) on corporate financial performance (CFP). Specifically, the mediating role of corporate reputation (CR) on the relationship between CSR and CFP is examined. We empirically investigate a sample of 3274 listed firms over the period 2009–2016 drawn from 25 countries located at Europe, Asia, Africa, and South and North America. Using four OLS regressions, we evince on the one side that CSR has a positive and direct impact on CFP. On the other side, we show that CR mediates the relationship between CSR and CFP: CSR has a significant and positive impact on CR and that CR has a significant and positive influence on CFP. The results of this study add to CSR‐related literature by providing international evidence and provide direction for a comparison across countries.

Published: April 2021

Cervical cancer is a major gynecological malignant tumor that threatens women's health. Current cytological methods have certain limitations for cervical cancer early screening. Light scattering patterns can reflect small differences in the internal structure of cells. In this study, we develop a light scattering pattern specific convolutional network (LSPS‐net) based on deep learning algorithm and integrate it into a 2D light scattering static cytometry for automatic, label‐free analysis of single cervical cells. An accuracy rate of 95.46% for the classification of normal cervical cells and cancerous ones (mixed C‐33A and CaSki cells) is obtained. When applied for the subtyping of label‐free cervical cell lines, we obtain an accuracy rate of 93.31% with our LSPS‐net cytometric technique. Furthermore, the three‐way classification of the above different types of cells has an overall accuracy rate of 90.90%, and comparisons with other feature descriptors and classification algorithms show the superiority of deep learning for automatic feature extraction. The LSPS‐net static cytometry may potentially be used for cervical cancer early screening, which is rapid, automatic and label‐free.

As the size and complexity of high‐dimensional (HD) cytometry data continue to expand, comprehensive, scalable, and methodical computational analysis approaches are essential. Yet, contemporary clustering and dimensionality reduction tools alone are insufficient to analyze or reproduce analyses across large numbers of samples, batches, or experiments. Moreover, approaches that allow for the integration of data across batches or experiments are not well incorporated into computational toolkits to allow for streamlined workflows. Here we present Spectre, an R package that enables comprehensive end‐to‐end integration and analysis of HD cytometry data from different batches or experiments. Spectre streamlines the analytical stages of raw data pre‐processing, batch alignment, data integration, clustering, dimensionality reduction, visualization, and population labelling, as well as quantitative and statistical analysis. Critically, the fundamental data structures used within Spectre, along with the implementation of machine learning classifiers, allow for the scalable analysis of very large HD datasets, generated by flow cytometry, mass cytometry, or spectral cytometry. Using open and flexible data structures, Spectre can also be used to analyze data generated by single‐cell RNA sequencing or HD imaging technologies, such as Imaging Mass Cytometry. The simple, clear, and modular design of analysis workflows allow these tools to be used by bioinformaticians and laboratory scientists alike. Spectre is available as an R package or Docker container. R code is available on Github (https://github.com/immunedynamics/spectre).
