Published: August 2021

Gene silencing is the epigenetic regulation of any gene in order to prevent gene expression at the transcription or translation levels. Among various gene silencing techniques, RNA silencing (RNAi) is notable gene regulation technique that involves sequence-specific targeting and RNA degradation. However, the effectiveness of transgene-induced RNAi in F1 generation of chrysanthemum has not been studied yet. In the current study, we used RNAi-constructed CmTFL1 (white-flowered) and CmSVP overexpressed (yellow flowered) transgenic plants of previously conducted two studies for our experiment. Cross hybridization was performed between these intergeneric transgenic and non-transgenic plants of the winter-growing chrysanthemum selection “37” (light pink flowered). The transgene CmSVP was confirmed in F1 hybrids by RT-PCR analysis, whereas hybrids of CmTFL1 parental plants were non-transgenic. Besides this, quantitative real-time PCR (qPCR) was used to explain the molecular mechanism of flower development using reference genes. Intergeneric and interspecific hybrids produced different colored flowers unlike their respective parents. These results suggest that generic traits of CmSVP overexpressed plants can be transferred into F1 generations when crossed with mutant plants. This study will aid in understanding the breeding phenomenon among intergeneric hybrids of chrysanthemum plants at an in vivo level, and such transgenics will also be more suitable for sustainable flower yield under a low-light production system.

Published: August 2021

Abelmoschus esculentus has fruit popularly known as okra and belongs to the Malvaceae family. It is commonly used in cooking but also in traditional medicine in the treatment of worms, dysentery, inflammation, and also irritation of the stomach, intestines, and kidneys, as it is a potential functional food. Its mucilage is a highly viscous polysaccharide that is mostly composed of monosaccharides D-galactose, L-rhamnose, and galacturonic acid, as well as proteins and minerals. The functional properties of okra mucilage have been widely studied, mainly for its potential antidiabetic activity; thus, its use as adjuvant or nutraceutical therapy for diabetes is very promising. Due to its rheological properties, it is a potential resource for pharmaceutical and food applications. Okra mucilage can be extracted by several methods, which can directly influence its physicochemical characteristics and biological activity. Features such as low cost, non-toxicity, biocompatibility, and high availability in nature arouse the interest of researchers for the study of okra mucilage. The survey of research on the applications of okra mucilage highlights the importance of using this promising source of bioactive compounds with interesting technological properties. The potential of okra as a functional food, the properties of okra mucilage, and its technological applications are discussed in this review.

Published: August 2021

Analgesic drugs like morphine and non-steroidal anti-inflammatory drugs exhibit several harmful effects. Here, we show for the first time the analgesic activity of Ficus palmata L. fruit extract (FPFE) on different analgesic rat models along with the in silico studies of some of the main phytochemicals of this plant. We performed in vivo pain models, along with in silico docking studies against the active site of COX-2 protein and mu-opioid receptors. A significant (p < 0.05) analgesic effect of FPFE was observed, and it was found that rutin has good pose and score as compared to diclofenac and morphinan antagonist (X-ligand), and psoralen has binding affinity almost equal to diclofenac, but a lower binding affinity as compared to rutin. The results proved that F. palmata fruits have the potential to ameliorate painful conditions.

Published: August 2021

The boron difluoride complex is known as an extraordinary class of fluorescent dyes, which has attracted research interest because of its excellent properties. This article reports the optical properties such as absorption, fluorescence, molar absorptivity, and photo-physical parameters like dipole moment, and oscillator strength of new fluorescent organic dye based on boron difluoride complex 2-(1-(difluoroboraneyl)-1,2-dihydroquinolin-2-yl)-2-(1-methylquinoxalin-2-ylidene) acetonitrile (DBDMA). The spectral characterization of the dye was measured in sol-gel glass, photosol-gel, and organic–inorganic matrices. The absorption and fluorescence properties of DBDMA in sol-gel glass matrices were compared with each other. Compared with the classical sol-gel, it was noticed that the photosol-gel matrix is the best one with immobilized DBDMA. In the latter, a large stokes shift was obtained (97 nm) and a high fluorescence quantum yield of 0.5. Special attention was paid to the addition of gold NPs into the hybrid material. The fluorescence emission intensity of the DBDMA with and without gold nanoparticles in different solid media is described, and that displayed organic–inorganic matrix behavior is the best host.

Concerns over the past few decades have focused, more than ever, on finding and implementing efficient, handy, and renewable sources to reduce pollution. Biomass, in general, and biomass from annual vine cuttings, are renewable sources that can be used by a large amount of the population. Biomass densification in the form of briquettes is an efficient method of obtaining a biofuel with the same characteristics as wood. The production of densified material as a briquette consists of sampling, drying naturally, chopping, grinding and briquetting the vine cuttings. The obtained results showed that the size of the briquettes met the requirements imposed by the standard, with a length between 185 mm and 400 mm and a diameter of 58 ± 0.75 mm, the humidity of the briquettes varying between 5.42%, at Sauvignon Blanc and 7.98% for Pinot Noir, while the durability of the briquettes registered minimum values of 98.17% for Muscat Ottonel and a maximum of 99.14% for Feteasca Neagra, and a unit density with values between 1227 kg/m3 for Feteasca Alba and 1389 kg/m3 for Pinot Noir. The conclusions of these experiments are promising, showing that the densification of biomass from vines cuttings qualifies within the standard requirements for obtaining a valuable biofuel.
A Parametric Numerical Study for Diagnosing the Failure of Large Diameter Bored Piles Using Supervised Machine Learning Approach
Authors: Al-Atroush Mohamed E. , Hefny Ashraf M. , Sorour Tamer M.
Published: August 2021

The full-scale static pile loading test is without question the most reliable methodology for estimating the ultimate capacity of large diameter bored piles (LDBP). However, in most cases, the obtained load-settlement curves from LDBP loading tests tend to increase without reaching the failure point or an asymptote. Loading an LDBP until reaching apparent failure is seldom practical because of the significant amount of settlement usually required for the full shaft and base mobilizations. With that in mind, the supervised learning algorithm requires a huge labeled data set to train the machine properly, which makes it ideal for sensitivity analysis, forecasting, and predictions, among other unsupervised algorithms. However, providing such a huge dataset of LDBP loaded to failure tests might be very complicated. In this paper, a novel practice has been proposed to establish a labeled dataset needed to train supervised machine learning algorithms on accurately predicting the ultimate capacity of an LDBP. A comprehensive numerical parametric study was carried out to investigate the effect of both pile geometrical and soil geotechnical parameters on both the ultimate capacity and settlement of an LDBP. This study was based on field measurements of loaded to failure LDBP tests. Results of the 29 applied models were compared with the calibrated model results, and the variation in LDBP behavior due to change in any of the hyperparameters was discussed. Accordingly, three primary characteristics were identified to diagnose the failure of LDBPs. Those characteristics were utilized to establish a decision tree of a supervised machine learning algorithm that can be used to predict the ultimate capacity of an LDBP.
Joint Estimation of SOC of Lithium Battery Based on Dual Kalman Filter
Authors: Wang Hao , Zheng Yanping , Yu Yang
Published: August 2021

In order to improve the estimation accuracy of the state of charge (SOC) of electric vehicle power batteries, a dual Kalman filter method based on the online identification of model parameters is proposed to estimate the state of charge in lithium-ion batteries. Here, we build the first-order equivalent circuit model of lithium-ion batteries and derive its online identification model based on extended Kalman (EKF). Considering that the noise value in the EKF algorithm is difficult to select through experiments to achieve the best filtering effect, this paper combines an improved particle swarm optimization algorithm (IPSO) with EKF to realize online model parameter identification. At the same time, the EKF filtering method derived from the state space equation is also used in SOC estimation. It constitutes a dual Kalman filter method for online identification of model parameters and SOC estimation. The experimental and simulation results show that the IPSO–EKF algorithm can adaptively adjust the noise value according to the complex operating conditions of electric vehicles. Compared with the EKF algorithm, our algorithm can identify battery model parameters more accurately. The dual Kalman filter method composed of the IPSO–EKF algorithm and EKF applied to SOC estimation achieved a higher accuracy in the final algorithm verification.

Authors: Winiczenko Radosław , Kaleta Agnieszka , Górnicki Krzysztof
Published: August 2021

The aim of the study was to estimate the optimal parameters of apple drying and the rehydration temperature of the obtained dried apple. Conducting both processes under such conditions is aimed at restoring the rehydrated apple to the raw material properties. The obtained drying parameters allow the drying process to be carried out in a short drying time (DT) and at low energy consumption (EC). The effect of air velocity (vd), drying temperature (Td), characteristic dimension (CD), and rehydration temperature (Tr) on rehydrated apple quality was studied. Quality parameters of the rehydrated apple as: color change (CC), mass gain ratio (MG), solid loss ratio (SL), volume gain ratio (VG) together with DT and EC were taken into consideration. The artificial neural network was used for modeling of rehydrated apple quality parameters, DT, and EC. A multi-objective genetic algorithm was developed in order to optimize parameters of the drying and rehydration processes. The simultaneous minimization of CC, SL, DT, EC, and the maximization of MG and VG were considered with the following drying and rehydration processes parameters: Td: 50–70 °C, vd: 0.01–2 m/s, Tr: 20–70 °C. The best solution has been found at drying temperature 56.1 °C, air velocity 1.3 m/s, characteristic dimension 2.0 mm, and rehydration temperature 59.2 °C. This apple drying and rehydration resulted in MG = 3.51, SL = 0.57, VG = 4.77, CC = 11.2, DT = 5.4 h, EC = 159.8 GJ/kg. The parameters of apple drying and rehydration processes can be recommended for the industry application.

For proton exchange membrane fuel cells (PEMFCs), the parameter extraction issue is among the most widely studied problems in the field of energy storage systems, since the precise identification of such parameters plays an important role in increasing the PEMFC performance and life span. The optimization process is intended to adjust the performance of PEMFCs by appraising the optimal parameters that produce a good estimation of the current–voltage (I–V) curve. In order to build an accurate equivalent circuit model for PEMFCs, a reliable and effective parameter extraction algorithm, termed a supply–demand-based optimization (SDO) algorithm, is proposed in this paper. Nine parameters (ξ1, ξ2, ξ3, ξ4, Rc, β, λ, l, and Jmax) are evaluated, to minimize the sum squared deviation (SSE) between the experimental and simulated I–V curves. To validate the feasibility and effectiveness of the SDO algorithm, four sets of experimental data with diverse characteristics and two well-known PEMFC stacks (BSC500W and 500W Horizon) are employed. Comparison of the simulated and experimental results clearly demonstrates the superiority/competitiveness of the SDO algorithm over five well-established parameter extraction algorithms, i.e., the whale optimization algorithm (WOA), grey wolf optimization (GWO), Harris hawks optimization (HHO), and genetic algorithm (GA). Several evaluation criteria, including best SSE, worst SSE, mean SSE, and standard deviation, show that the SDO algorithm has merits in terms of PEMFC modeling.
Mauritians and Latter-Day Saints: Multicultural Oral Histories of The Church of Jesus Christ of Latter-Day Saints within “The Rainbow Nation”
Authors: Chintaram Marie Vinnarasi
Published: August 2021

The Church of Jesus Christ of Latter-day Saints emerged within the Mauritian landscape in the early 1980s after the arrival of foreign missionary work. With a population of Indian, African, Chinese, French heritage, and other mixed ethnicities, Mauritius celebrates multiculturalism, with many calling it the “rainbow nation”. Religiously, Hinduism dominates the scene on the island, followed by Christianity (with Catholicism as the majority); the small remainder of the population observes Islam or Buddhism. Although Mauritian society equally embraces people from these ethnic groups, it also has historically marginalized communities who represent a “hybrid” of the mentioned demographic groups. This article, based on ethnographic research, explores the experiences of Mauritian Latter-day Saints as they navigate the challenges and implications of membership in Mormonism. Specifically, it focuses on how US-based Mormonism has come to embrace the cultural heritage of people from the various diaspora and how Mauritian Latter-day Saints perceive their own belonging and space-making within an American born religion. This case study presents how the local and intersecting adaptations of language, race, and local leadership within a cosmopolitan society such as Mauritius have led to the partial hybridization of the Church into the hegemony of ethnic communities within Mauritian Latter-day Saint practices. These merging of cultures and world views prompts both positive and challenging religious experiences for Mauritian Church members. This article illustrates the implications and pressures of the Church trying to globalize its faith base while adapting its traditionally Anglocentric approaches to religious practices to multiracial, multicultural cosmopolitan communities such as Mauritius.
How Just Culture and Personal Goals Moderate the Positive Relation between Commercial Pilots’ Safety Citizenship Behavior and Voluntary Incident Reporting
Authors: Sieberichs Sebastian , Kluge Annette
Published: August 2021

Flight safety is consistently influenced by pilots’ self-inflicted incidents in routine flight operations. For airlines, pilots’ reports on these incidents are essential input to learn from incidents (LFI) and for various safety management processes. This paper aims to explain the voluntary reporting behavior of pilots’ self-inflicted incidents from an occupational safety perspective. We investigate how the relation between pilots’ safety citizenship behavior (SCB) and reporting behavior is moderated by pilots’ fear, shame, goals, and goal-striving when reporting, as well as the influence of a just culture on the decision to report incidents. In total, 202 German commercial pilots participated in an online survey. The results showed that reporting behavior can be considered a specific form of self-intentional SCB, but should be differentiated into subtypes depending on a pilot’s unsafe acts (errors or violations) that caused the incident. Reporting behavior-specific motivational factors influenced different subtypes of reporting behavior: Just culture moderated a positive relation between SCB and reported incidents caused by violations. Moreover, depending on the subtype of reporting behavior, the relation was moderated by different types of goals in relation to the pilots. No moderating effects of fear or shame could be demonstrated. Our findings highlight the value of a just culture for encouraging goal-oriented reporting behavior in the context of LFI and safety management.
Memorial Ambivalences in Postcommunist Romania: Generational Attitudes towards the Symbolic Legacy of Communism
Authors: Rusu Mihai Stelian , Croitoru Alin
Published: August 2021

After the demise of state socialism, public space became an issue of contention that occupied an important place within societies’ efforts to come to terms with the recent past. Extant scholarship documented extensively how postcommunist societies in Central and Eastern Europe have reconfigured the public space by removing the symbolic presence of the former regime (e.g., monuments and statues, but also place- and street names). However, there is a scarcity of research done on exploring the reception of these broad changes brought to the public statuary and urban nomenclature. In this study, we aim to contribute to this nascent strand of literature by investigating the generational differences in social attitudes towards the symbolic transformation of public space in postcommunist Romania. Data collected through a national web-survey conducted in February 2021 (n = 1156) revealed significant intergenerational differences regarding the removal of monuments and the renaming of streets. In particular, higher approval of such memory work was found among the generations born during communism in comparison to the postcommunist generation. Taking stock of these generational differences, as well as the factors underpinning them, contributes to a better understanding of how ordinary people relate to the politics of memory enacted in transforming societies.

Published: August 2021

Next Generation Science Standards science and engineering practices (NGSS S&E) are ways of eliciting reasoning and applying foundational ideas in science. Studies have revealed one major impediment to implementing the NGSS, namely, insufficient teacher preparation, which is a concern at all teaching levels. The present study examined a program grounded in research on how students learn science and engineering pedagogical content knowledge and strategies for incorporating NGSS S&E practices into instruction. The program provided guided teaching practice, content learning experiences in the physical sciences, engineering design tasks, and extended projects. Research questions included: To what extent did the Program increase teachers’ competence and confidence in science content, with emphasis on science and engineering practices? To what extent did the program increase teachers’ use of reformed teaching practices? This mixed-methods, quasi-experimental design examined teacher outcomes in the program for 24 months. The professional development (PD) findings revealed significant increases in teachers’ competence and confidence in integrating science and engineering practices in the classroom. These findings and their specificity contribute to current knowledge and can be utilized by districts in selecting PD to support teachers in preparing to implement the NGSS successfully.
The Origin of Intergalactic Light in Compact Groups of Galaxies
Authors: Henriksen Mark
Published: August 2021

We investigate the origin of intergalactic light (IGL) in close groups of galaxies. IGL is hypothesized to be the byproduct of interaction and merger within compact groups. Comparing the X-ray point source population in our sample of compact groups that have intergalactic light with compact groups without IGL, we find marginal evidence for a small increase in ultra-luminous X-ray sources (ULXs). There is also a significant bias towards lower luminosity high mass X-ray binaries (HMXRBs). We interpret this as an indication that groups with visible IGL represent a later evolutionary phase than other compact groups. They have galaxies characterized by quenching of star formation (lower star formation rate (SFR) inferred from lower HMXRB luminosity) after stellar material has been removed from the galaxies into the intergalactic medium, which is the source of the IGL. We conclude that the presence of an increased fraction of ULXs is due to past interaction and mergers within groups that have IGL.

Published: August 2021

Due to frequent cardiorespiratory events (CREs) in response to the first routine immunization (rIM), current guidelines recommend readmitting and monitoring extremely preterm infants after the second rIM, though evidence on CREs in response to the second rIM is weak. In a prospective observational study, preterm infants with an increase in CREs after the first rIM were monitored for CREs before and after the second rIM. Seventy-one infants with a median gestational age of 26.4 weeks and a median weight of 820 g at birth were investigated at a median postnatal age of 94 days. All but seven infants showed an increase in CREs after the second rIM. The frequency of hypoxemias (p < 0.0001), apneas (p = 0.0003) and cardiorespiratory events requiring tactile stimulation (CRE-ts) (p = 0.0034) increased significantly. The 25 infants (35%) presenting with CRE-ts were significantly more likely to have been continuously hospitalized since birth (p = 0.001) and to receive analeptic therapy at the first rIM (p = 0.002) or some kind of respiratory support at the first (p = 0.005) and second rIM (p < 0.0001). At a postmenstruational age of 43.5 weeks, CRE-ts ceased. Our data support the recommendation to monitor infants who fulfil the above-mentioned criteria during the second rIM up to a postmenstruational age of 44 weeks.

In this study, the ability of the combined vaccine against peste des petits ruminants (PPR) (Nigeria strain 75/1) and sheep pox (SPP) (NISKhI strain) to form a protective immune response for 12 months in Kazakh breed fine-fleeced sheep aged 6–12 months was demonstrated. The duration of the protective immunity of immunized sheep from PPR and from SPP was evaluated using a serum neutralization test (SNT), followed by testing of the resistance of vaccinated sheep to infection with the field strain Kentau-7 of the PPRV and the virulent strain A of the SPPV. The PPR antibody response was additionally measured by c-ELISA. A single immunization of sheep with a combined vaccine in a volume of 2.0 mL, containing the PPR and SPP vaccine viruses in the titers of 103.0 TCID50/mL, provided reliable protection of animals from two infections simultaneously for 12 months (observation period). At the same time, in sheep immunized with the combined vaccine, antibodies of PPRV persisted for up to 12 months, with slight fluctuations. The combined vaccine induced 100% clinical protection against the field strain of PPRV and the virulent strain of SPPV in immunized sheep for up to 12 months, while unvaccinated animals became ill with the manifestation of clinical signs specific to PPRV and SPPV.

Purpose: Clinical significance and durability of serological response after mRNA COVID-19 vaccines is under investigation. Data on early virological response are limited. To iden-tify potential predictors of antibody durability, circulating antibody levels were longitudinally ex-plored in healthcare workers included in a follow-up program for SARS-CoV-2 infection. Meth-ods: Subjects meeting the inclusion criteria signed an informed consent. Serum samples were col-lected at baseline, before the first BNT162b2 vaccine, at days 7, 21, 31, 90, and 180 days after the first dose. Serological evaluation was performed by QuantiVac Euroimmune anti-S1 antibody as-say. Only subjects followed-up until day 90 are here considered. Results: Of 340 taken into consid-eration, 265 subjects were naive, and 75 COVID-19 experienced. The former showed a progres-sive increase in their antibody levels before day 90 decline, while the latter showed antibody levels reaching a plateau at day 7 and slightly declining at day 90. All showed antibody levels higher than the assay cut-off at day 31 and 90. Among naive, 108 had an early response whose predic-tors were younger age and female gender (OR 0.94, 95% CI 0.91–0.96, p < 0.0001; and OR 2.58, 95% CI 1.48–4.51, p = 0.0009). Naive subjects experienced a day 30/90 decline in antibody levels, whereas experienced did not. Early response was an independent predictor of higher day 30/90 antibody levels decline (OR = 2.05, 95% CI 1.04–4.02; p = 0.037). Conclusions: Our results suggest that in healthcare workers early response might be inversely associated with antibody levels 90 days after BNT162b2 vaccine.

Cultural universalization of consumption in the context of globalization
Authors: Petrov I.F.
Published: August 2021

The paper is devoted to the cultural universalization of consumption in the context of globalization. It is shown that national communities today are not considered as political entities, but rather as economic entities, parts of the consumer market. Globalization leads to the creation of a single world, but not of an open and varied world. This world does not have a pluralistic and cosmopolitan view of itself and others, but, on the contrary, is rather a single commodity world. In it, local cultures and identities lose their roots and are replaced by symbols of the commodity world.

Published: August 2021

As with other animal species, one of the most important challenges encountered in race horse breeding is performance and economic losses caused by infectious diseases. Antibiotics are the most important and common drugs used for protection against infectious diseases. Recently with the occurrence of antibiotic resistance, serious complications have emerged in terms of human and animal health. For this reason, to determine antibiotic resistance in bacteria, many research studies have been carried out in the world and Türkiye. However, in Türkiye no comprehensive study has yet been conducted on antibiotic resistance in race horses. Within the scope of this study, it was aimed to investigate antibacterial susceptibility and resistance in Streptococcus spp. and Staphylococcus spp. agents identified through isolation from tracheal aspiration fluid samples taken from thoroughbred horses brought to 75. Yıl Hippodrome Hospital. Disk Diffusion and Minimum Inhibitory Concentration (MIC) tests were used to determine antibacterial susceptibility. Susceptibility profiles of identified strains against some penicillin, cephalosporin, aminoglycoside, tetracycline, rifamycin and carbapenem group antibacterial drugs were determined. Also, it has been determined that 1 Streptococcus spp. and 10 Staphylococcus spp. agents are sensitive to amoxicillin and ampicillin-sulbactam; moderately sensitive to penicillin and amikacin and resistant to trimethoprim-sulfamethoxazole, kanamycin, gentamicin, enrofloxacin and rifampin.
Molecular diagnosis of neglected infectious agents of heep and attle abortions: the prevalences of Coxiella burnetii, Francisella tularensis and Chlamydophila abortus at a glance
Authors: KARATAŞ YENİ Derya
Published: August 2021

Bacterial abortive agents such as Brucella spp., Salmonella spp., Campylobacter spp., Listeria spp. cause serious infections that lead to significant economic losses in cattle and sheep breeding. These bacteria can be easily cultured under in vitro laboratory conditions. Abortions caused by intracellular bacteria such as Coxiella burnetii (C. burnetii), Chlamydophila abortus (C. abortus) and Francisella tularensis (F. tularensis) are less prevalent in abortive cases and the diagnosis of these bacteria, many of which need to cell culture for cultivation and biosafety level-3 laboratory facilities for safe working, can be made by PCR. In this study, it was aimed to determine the molecular prevalence of C. burnetii, C. abortus and F. tularensis agents, which were neglected during the diagnosis of abortions, in cattle and sheep collected from different regions of Türkiye. A total of 395 clinical materials were analyzed via agent-specific commercial Real-Time PCR. As a result, the molecular prevalence of F. tularensis, C. burnetii and C. abortus was determined as 14%, 2.9% and 2.28%, respectively. F. tularensis in cattle clinical samples and C. burnetii in sheep clinical samples were not found. This is the first report that F. tularensis was found as an agent in an abortive material in Türkiye. Although it differs in terms of prevalence, it has been determined that these microorganisms, which are neglected in routine diagnosis, can be spread with aborted materials, especially vaginal discharge, which may pose a risk of transmission.

A modelagem computacional do escoamento sanguíneo em árvores arteriais do sistema circulatório ajuda a ganhar entendimento deste complexo sistema, o que pode auxiliar no tratamento de doenças vasculares. Para tanto, a construção de modelos de árvores arteriais é mandatória para representar a rede vascular em detalhe de domínios anatômicos com escassez de dados morfométricos dos vasos. Na literatura, há as seguintes classes de modelos de árvores arteriais: anatômico, parâmetros condensados, fractal e otimizado. No contexto do modelo otimizado, os modelos gerados pelo método CCO (Constrained Constructive Optimization) são capazes de reproduzir características morfométricas e hemodinâmicas de árvores arteriais reais. Neste trabalho, é proposto um algoritmo baseado no método CCO capaz de gerar modelos de árvores arteriais em domínios 2D/3D não necessariamente convexos sob as seguintes condições: raio do segmento raiz fixo, fluxos distintos nos segmentos terminais e diferentes expoentes na lei de bifurcação durante o crescimento da árvore. Esse algoritmo é chamado de VCCO (Variant of the Constrained Constructive Optimization). Dados morfométricos dos modelos gerados pelo algoritmo foram comparados com dados reais de árvores arteriais coronarianas. Com relação à hemodinâmica, a impedância vascular nos modelos de árvores arteriais foi calculada e comparada com dados experimentais e numéricos. Por último, simulações de escoamento pulsátil foram realizadas utilizando um método analítico e modelos de árvores arteriais como substrato geométrico. Os resultados morfométricos e hemodinâmicos obtidos neste trabalho estão em concordância com dados numéricos e experimentais da literatura, o que sugere que o Algoritmo VCCO produz modelos confiáveis que podem ser utilizados em simulações hemodinâmicas.

Employee assessment is needed in evaluating performance and granting rewards to employees. PT. Kupu-Kupu Taman Lestari conducts an employee performance appraisal using Microsoft Excel. The growth of employee data and assessment variables resulted in the calculation method that was carried out could not provide employee ranking information quickly. The application of Microsoft Excel in processing employee valuation data has weaknesses in data documentation. The purpose of this study is the company has a website-based decision support system that makes it easy for companies to get employee performance appraisal information. The employee performance data ranking method used is the Analytical Network Process (ANP) and the performance evaluation criteria are prepared based on the Behaviorally Anchor Rating Scale (BARS) approach. BARS is used in determining criteria along with a scale of behavior that represents the performance of each criterion. ANP is used to process data of importance between criteria so that it can produce criteria weights based on a comparison between criteria. The results of this study are website-based decision support systems that can be accessed by company management via a web browser. System testing is built based on testing manual calculations with the system and testing the user's system according to the McCall model. The system calculation test shows that the system has produced the same calculation value as the manual calculation. System user testing shows that the system built meets user needs, displays information according to user input correctly, is safe from unauthorized parties, and the system is easy to use.

Along with the development of the world of science, it is getting faster ICT in education. The objectives to be achieved in this study are to find out how the student's response to the utilization of the Hawgent Dynamic Mathematics application on the material of the curved side of the learning room in the teaching and learning process took place in the classroom. The main object in this study was the 9th-grade junior high school student who was 96 students at Gusui Middle School in Guangxi Zhuang Autonomous Region. Data collection in this study was a questionnaire containing indicators that have to measure the student's response to the use of learning media using Hawgent Dynamic Mathematics and the primary tool processing research data, namely Ms. Excel and SPSS statistical. The study results were related to the student's response that students agreed, were happy, and were assisted by the Hawgent Dynamic application. The perception or student response results concluded that learning using Hawgent Dynamic software could help in mathematics. It was easier and satisfying for students to understand the material about building a curved side space. However, the use of Hawgent software was only limited to trials, so it was recommended that it be able to use and utilize this software for other discussions on mathematics lessons.
A linguagem metacientífica no ensino de ciências
Authors: Hidalgo Maycon Raul , Lorencini Júnior Álvaro
Published: August 2021

Buscou-se neste trabalho identificar como licenciandos do curso de Ciências Biológicas, de uma universidade pública do estado do Paraná, compreendem os termos relativos à linguagem metacientífica, como leis, teorias e hipóteses. Para a coleta de dados, utilizaram-se questionários descritivos e entrevistas semiestruturadas e os dados foram submetidos à análise textual discursiva. Os resultados demonstraram que os licenciandos apreendem de forma equivocada os elementos da linguagem metacientífica. Em geral, perceberam-se equívocos entre os termos teoria e hipótese, assim como nos significados relativos ao termo lei, além de uma tendência em atribuir gradações entre os conceitos de teoria e lei. Entende-se, assim, ser necessário que haja a inserção de discussões sobre a linguagem metacientífica no processo de formação de professores de ciências, evitando-se que esses equívocos se consolidem entre tais profissionais e consequentemente se estendam aos estudantes da educação básica.

It is interesting to note that the adverse effect of this genotype was observed exclusively in patients with ronchopathy, while in patients with ronchopathy, the frequency of this genotype did not differ in comparison with the control group, i.e. there is a significant tendency to an increase in the genotype with an increase in the severity of the pathology. Material and methods. To solve the set tasks, 208 patients with various diseases of the upper respiratory tract, with nasal breathing disorders, causing ronchopathy, who were hospitalized in the ENT department of the multidisciplinary clinic of the Tashkent Medical Academy for 2015 to 2021, were examined. The control group consisted of 50 apparently healthy people who agreed to participate in the study (students, masters, clinical residents). Among the sick men there were 144 (73%), women - 64 (27%). The age of the patients ranged from 18 to 70 years, averaging 44.5 ± 6.8 years. Molecular genetic studies were carried out in the Department of Molecular Medicine and Cell Technologies of the RSNPMC Hematology. This part of the work consisted of several stages: 1. Blood sampling. 2. Isolation of DNA from peripheral blood lymphocytes. 3. Carrying out PCR. 4. Conducting electrophoresis and visualizing the results (if necessary). The analysis of the TGFb1 gene polymorphism associations was carried out using a case-control model (casecontrol, comparison of two samples). The sample "case" was formed from 104 patients with ronchopathy. Conclusion. Since this work is one of the few works on the study of the relationship between rs 2010963 of the VEGFA gene and the risk of developing ronchopathy, our data may become the subject of further discussions.
