In the past few years, the world has suffered from an untreated infectious epidemic disease (COVID-19), caused by the so-called coronavirus, which was regarded as one of the most dangerous and viral infections. From this point of view, the major objective of this intended paper is to propose a new mathematical model for the coronavirus pandemic (COVID-19) outbreak by operating the Caputo fractional-order derivative operator instead of the traditional operator. The behavior of the positive solution of COVID-19 with the initial condition will be investigated, and some new studies on the spread of infection from one individual to another will be discussed as well. This would surely deduce some important conclusions in preventing major outbreaks of such disease. The dynamics of the fractional-order COVID-19 mathematical model will be shown graphically using the fractional Euler Method. The results will be compared with some other concluded results obtained by exploring the conventional model and then shedding light on understanding its trends. The symmetrical aspects of the proposed dynamical model are analyzed, such as the disease-free equilibrium point and the endemic equilibrium point coupled with their stabilities. Through performing some numerical comparisons, it will be proved that the results generated from using the fractional-order model are significantly closer to some real data than those of the integer-order model. This would undoubtedly clarify the role of fractional calculus in facing epidemiological hazards.

Published: December 2022

Integral operators with the Mittag–Leffler function in kernels play a very vital role in generalizing classical integral inequalities. This paper aims to derive Ostrowski-type inequalities for k-fractional integrals containing Mittag–Leffler functions. Several new inequalities can be deduced for various fractional integrals in particular cases. Applications of these inequalities are also given.

Published: December 2022

We present an analysis of the pitch angle distribution function (PADF) for nearby galaxies and its resulting black hole mass function (BHMF) via the well-known relationship between pitch angle and black hole mass. Our sample consists of a subset of 74 spiral galaxies from the Carnegie-Irvine Galaxy Survey with absolute B-band magnitude MB>−19.12 mag and luminosity distance DL≤25.4 Mpc, which is an extension of a complementary set of 140 more luminous (MB≤−19.12 mag) late-type galaxies. We find the PADFs of the two samples are, somewhat surprisingly, not strongly dissimilar; a result that may hold important implications for spiral formation theories. Our data show a distinct bimodal population manifest in the pitch angles of the Sa–Sc types and separately the Scd–Sm types, with Sa–Sc types having tighter spiral arms on average. Importantly, we uncover a distinct bifurcation of the BHMF, such that the Sa–Sc galaxies typically host so-called “supermassive” black holes (M•≳106M⊙), whereas Scd–Sm galaxies accordingly harbor black holes that are “less-than-supermassive” (M•≲106M⊙). It is amongst this latter population of galaxies where we expect fruitful bounties of elusive intermediate-mass black holes (IMBHs), through which a better understanding will help form more precise benchmarks for future generations of gravitational wave detectors.

Burmese python (Python bivittatus) is an invasive snake that has significantly affected ecosystems in southern Florida, United States. Aside from direct predation and competition, invasive species can also introduce nonnative pathogens that can adversely affect native species. The subfamily Serpentovirinae (order Nidovirales) is composed of positive-sense RNA viruses primarily found in reptiles. Some serpentoviruses, such as shingleback nidovirus, are associated with mortalities in wild populations, while others, including ball python nidovirus and green tree python nidovirus can be a major cause of disease and mortality in captive animals. To determine if serpentoviruses were present in invasive Burmese pythons in southern Florida, oral swabs were collected from both free-ranging and long-term captive snakes. Swabs were screened for the presence of serpentovirus by reverse transcription PCR and sequenced. A total serpentovirus prevalence of 27.8% was detected in 318 python samples. Of the initial swabs from 172 free-ranging pythons, 42 (24.4%) were positive for multiple divergent viral sequences comprising four clades across the sampling range. Both sex and snout-vent length were statistically significant factors in virus prevalence, with larger male snakes having the highest prevalence. Sampling location was statistically significant in circulating virus sequence. Mild clinical signs and lesions consistent with serpentovirus infection were observed in a subset of sampled pythons. Testing of native snakes (n = 219, 18 species) in part of the python range found no evidence of python virus spillover; however, five individual native snakes (2.3%) representing three species were PCR positive for unique, divergent serpentoviruses. Calculated pairwise uncorrected distance analysis indicated the newly discovered virus sequences likely represent three novel genera in the subfamily Serpentovirinae. This study is the first to characterize serpentovirus in wild free-ranging pythons or in any free-ranging North America reptile. Though the risk these viruses pose to the invasive and native species is unknown, the potential for spillover to native herpetofauna warrants further investigation.

The inland aquatic ecosystems play a significant role in the global carbon cycle, owing to the metabolism of terrestrially derived organic matter as it moves through fluvial networks along the water continuum. During this transport, dissolved organic matter (DOM) is microbial processed and released into the atmosphere, but the degree and intensity of this processing vary greatly both spatially and temporally. The Western Siberian Lowlands is of particular interest for a quantitative assessment of DOM biodegradation potential because the global areal-scale effects of DOM biodegradation in abundant surface organic-rich waters might be the highest in this region. To this end, we collected water samples along a typical aquatic continuum of the Bakchar Bog (the north-eastern part of the Great Vasyugan Mire) and, following standardized protocol, conducted an experimental study aimed at characterizing the seasonal and spatial variability of dissolved organic carbon (DOC) biodegradability. The biodegradable DOC fraction (BDOC) over the exposure incubation period ranged from 2% to 25%. The natural aquatic continuum “mire–forest–stream–river” demonstrated the systematic evolution of biodegradable DOC among the sites and across the seasons. The highest biodegradation rates were measured during spring flood in May and decreased along the continuum. The maximum possible CO2 production from DOM yielded the maximum possible flux in the range of 0.1 and 0.2 g C-CO2 m−2 day−1 d, which is an order of magnitude lower than the actual net CO2 emissions from the inland waters of the WSL. This study suggests that although the biodegradation of the humic waters of the WSL can sizably modify the concentration and nature of the DOM along the aquatic continuum, it plays only a subordinary role in overall C emissions from the lakes and rivers of the region.

Published: December 2022

The stationarity test and systematic prediction of hydrometeorological parameters are becoming increasingly important in water resources management. Based on the Ensemble Kalman Filter (EnKF) and wavelet analysis, this study selects precipitation, evaporation, temperature, and runoff as model variables, builds a model, tests and analyzes the stationarity of the hydrometeorological parameters of the Manas River, and forecasts the selected parameters for two years. The results of the study show that during the 2000–2020 study period, precipitation in the Manas River Basin on the northern slope of the Tianshan Mountains shows a significant downward trend from 2016 to 2020, with an annual average decline rate of 23.30 mm/a over five years. The proportion of runoff during the flood season also increases, with the statistical probability of an extremely low value of runoff increasing by 37.62% on average. After using wavelet decomposition to provide input to EnKF, the NSE of the model for the prediction of precipitation, evaporation, temperature, and runoff reached 0.86, 0.89, 0.96, and 0.9 respectively. At the same time, the K-S value increases from 0.28 to 0.40, which means that the wavelet analysis technique has great potential as a preprocessing of the Ensemble Kalman filter.
Plain Stilling Basin Performance below 30° and 50° Inclined Smooth and Stepped Chutes

Published: December 2022

Energy dissipators, such as stilling basins, are usually required at the toe of stepped chutes to achieve adequate and safe operation of the spillway. Stepped chute hydraulics has been extensively studied in last several decades, however, only limited knowledge is available on the stilling basin performance below stepped chutes. In particular, the effect of the chute slope remains unknown, despite being a central design issue. Therefore, an experimental campaign was performed using a 30° or 50° inclined smooth or stepped chute with an adjacent conventional plain stilling basin. The experimental results indicated that, within the stilling basin, the surface characteristics and the roller as well as hydraulic jump lengths are practically independent of the chute slope. This further strengthens the previous findings that stepped chutes require 17% longer dimensionless jump lengths and consequently stilling basin lengths. The experimental results also confirmed that stepped chutes generated increased extreme and fluctuating bottom pressure characteristics at the stilling basin entrance area. With increasing chute slope, the latter were found to significantly magnify. However, such increased magnitudes were not expected to provoke cavitation damage as stepped chute inflows induced bottom aeration at the basin entrance, irrespective of the chute slope.
Effective Removal of Biogenic Substances Using Natural Treatment Systems for Wastewater for Safer Water Reuse
Authors: Halicki Wojciech , Halicki Michał
Published: December 2022

Natural Treatment Systems for Wastewater (NTSW) show great potential for economic, socially acceptable and environmentally friendly wastewater treatment, along with the renewal of water for its safe reuse. This article presents the reduction in nitrogen and phosphorus compounds in domestic wastewater, which was achieved in a 2.5-year operation of the newly developed NTSW. The presented installation was developed by the Institute of Applied Ecology in Skórzyn (Poland) and implemented as a pilot plant serving the institute building with three permanent residents and up to five employees. The installation consisted of two parts, responsible for: wastewater treatment (septic tank and compost beds) and water renewal (denitrification beds, phosphorus beds and activated carbon beds). The mean values of nitrogen and phosphorus compound concentrations obtained in the renewed water for the entire research period were: 0.8, 49.4, 12 and 3.1 mg/L for ammonium nitrogen (NH4), nitrates (NO3), total nitrogen and phosphates (PO4), respectively. Thus, average reductions of 99.6%, 90.9% and 94.4% were obtained for NH4, total nitrogen and PO4, respectively. Treatment of domestic sewage to such a level, similar to drinking water, enables versatile, safe water reuse, which in the situation of increasingly limited water resources will constitute increasing ecological and economic value.

Published: December 2022

Polycyclic aromatic hydrocarbons (PAHs) distributed in air and soil are harmful because of their carcinogenicity, mutagenicity, and teratogenicity. Biodegradation is an environmentally friendly and economical approach to control these types of contaminants and has become an essential method for remediating environments contaminated with petroleum hydrocarbons. The bacteria are isolated and identified using a mineral nutrient medium containing PAHs as the sole source of carbon and energy and biochemical differential tests. Thus, this study focuses on some bacteria and fungi that degrade oil and hydrocarbons. This study provides a comprehensive, up-to-date, and efficient overview of petroleum hydrocarbon contaminant bioremediation considering hydrocarbon modification by microorganisms, emphasizing the new knowledge gained in recent years. The study shows that petroleum hydrocarbon contaminants are acceptably biodegradable by some microorganisms, and their removal by this method is cost-effective. Moreover, microbial biodegradation of petroleum hydrocarbon contaminants utilizes the enzymatic catalytic activities of microorganisms and increases the degradation of pollutants several times compared to conventional methods. Biological treatment is carried out in two ways: microbial stimulation and microbial propagation. In the first method, the growth of indigenous microorganisms in the area increases, and the pollution is eliminated. In the second method, on the other hand, there are no effective microorganisms in the area, so these microorganisms are added to the environment.

Published: December 2022

In Natural Landscape Complexes and Ecological Sites, local environmental protection is used to cover previous industrial activities, fragments of the cultural landscape, and habitats of both vertebrates and invertebrates. In water bodies within the different types of habitat protection, aquatic invertebrate fauna was studied to investigate whether it is a general rule that different forms of protection ensure the diversity of aquatic invertebrates in rural and industrial areas. The research revealed differences between invertebrate assemblages within complexes and between reservoirs. Compared with unprotected reservoirs located in the same area, in the majority of the studied water bodies, either no alien species were found or their relative abundance in assemblages was very low. Significant differences in the density, the number of taxa, the diversity, and the percentage of alien species were observed between different geographical locations. The location of water bodies within the protected area plays an important role in maintaining benthos diversity in industrial areas. These findings are useful for comparison with those of future research to document possible improvements or ongoing ecological regression in the quality of aquatic ecosystems in industrial areas. This study can help guide revisions of protected habitat networks for adequate protection of freshwater biodiversity in industrial areas.

Authors: Nguyen Lam Van , Seidu Razak
Published: December 2022

Predicting the condition of sewer pipes plays a vital role in the formulation of predictive maintenance strategies to ensure the efficient renewal of sewer pipes. This study explores the potential application of ten machine learning (ML) algorithms to predict sewer pipe conditions in Ålesund, Norway. Ten physical factors (age, diameter, depth, slope, length, pipe type, material, network type, pipe form, and connection type) and ten environmental factors (rainfall, geology, landslide area, population, land use, building area, groundwater, traffic volume, distance to road, and soil type) were used to develop the ML models. The filter, wrapper, and embedded methods were used to assess the significance of the input factors. A dataset consisting of 1159 inspected sewer pipes was used to construct the sewer condition models, and 290 remaining inspections were used to verify the models. The results showed that sewer material and age are the most significant factors, otherwise the network type is the least contributor affecting the sewer conditions in the study area. Among the considered ML models, the Extra Trees Regression (R2 = 0.90, MAE = 11.37, and RMSE = 40.75) outperformed the other ML models and it is recommended for predicting sewer conditions for the study area. The results of this study can support utilities and relevant agencies in planning predictive maintenance strategies for their sewer networks.

Published: December 2022

The ability of smallholder dairy farming systems (SHDFS) to achieve desirable lactation-curve characteristics is constrained or reduced by environmental stresses. Under stressful production environments in the tropics, the better lactation-curve characteristics in smallholder dairy farms are a result of improved dairy genetics and husbandry practices. Better husbandry practices improve animal health and welfare status, which is important to sustain SHDFS in the tropics where dairy cattle are constantly exposed to multiple environmental stresses of feed scarcity, disease infections and heat load. In this case, lactating cows in smallholder dairy farms labelled positive deviants are expected to express lactation curve characteristics differently from typical farms, regardless of the stress levels confronted. Thus, this study tested this hypothesis with Holstein–Friesian and Ayrshire cows in two milksheds in Tanzania classified them into low-and high-stress environments. A two-factor nested research design was used, with farm (positive deviant and typical) nested within the environment. Positive deviant farms were farms that performed above the population average, attaining ≥0.35 Mcal NEL/d energy balance, ≥6.32 L/cow/day milk yield, ≤1153.28 days age at first calving, ≤633.68 days calving interval and ≤12.75 per 100 animal-years at risk disease-incidence density. In this study, a total of 3262 test-day milk production records from 524 complete lactations of 397 cows in 332 farms were fitted to the Jenkins and Ferrell model to estimate lactation curve parameters. In turn, the outcome parameters a and k were used to estimate lactation curve characteristics. The lactation curve characteristic estimates proved the study hypothesis. Regardless of the stress levels, cows in positive deviant farms expressed lactation curve characteristics differently from cows managed in typical farms. The scale (a) and shape (k) parameters together with peak yield and time to peak yield indicated higher lactation performance in positive deviant farms than in typical farms under low- and high-stress environments (p < 0.05). Lactation persistency was higher in positive deviants than typical farms by 14.37 g/day and 2.33 g/day for Holstein–Friesian cows and by 9.91 g/day and 2.16 g/day for Ayrshire cows in low- and high-stress environments. Compared to cows managed in typical farms, cows in positive deviant farms attained higher lactation performance under low- and high-stress; Holstein–Friesian produced 50.2% and 36.2% more milk, respectively, while Ayrshire produced 52.4% and 46.0% more milk, respectively. The higher milk productivity in positive deviant farms can be associated with the deployment of husbandry practices that more effectively ameliorated feed scarcity, heat load and disease infections stresses, which are prevalent in tropical smallholder dairy farms.

METHODS OF PEDAGOGICAL STIMULATION OF THE FUTURE TEACHER TO SELF-ASSESSMENT IN EDUCATIONAL ACTIVITY
Authors: Mamon O. , Halchenko D.
Published: December 2022

During the research, based on a thorough study of various definitions related to the concept of "pedagogical stimulation", we have formed up the following definition: pedagogical stimulation is the purposeful use of didactic tools in the process of self-affirmation and activation of the intellectual and moral potential of the agent of learning process, taking into account his personality characteristics.Among the methods of pedagogical stimulation of the future teacher to self-assessment in edu- cational activity, we identified and characterized four key groups: the formation of cognitive interest and the development of a positive emotional attitude to self-assessment in educational activities; formation of the sense of duty and responsibility in teaching; to bolster the motivation influence in training group; to encourage students to overcome obstacles to learning.The students who have already experienced some difficulties in learning require the development of cognitive interest as well as of a positive emotional attitude towards the self-assessment in educational activities. Thus we consider the introduction of a comfortable moral and psychological atmosphere to be the essential condition for the method to be implemented. It is manifested in verbal encouragement when the students are performing their tasks and projects, in situations when a student has achieved positive results.The method of forming a sense of duty and responsibility in learning encourages students to be actively engaged in certain activities and at the same time it impedes their inappropriate actions. The content of the method is to focus on students’ individual rights as members of the team, future specialists, as well as on the moral assessment of their activities.The use of motivational influence of the educational group is a method of pedagogical stimulation, which integrates all other methods of stimulation and involves students in the development and presentation their socially and morally valuable requirements to each other, it encourages to setting and implementation of socially and personally significant perspectives and it influences the effectiveness of promotion and punishment .The incentive to overcome the barriers in learning is planned by the teacher and is based on the student's bias on priority, leadership, primacy, self-affirmation. Different forms of overcoming obstacles are implemented at higher educational establishments: competitions, festivals, projects, exhibitions, quizzes, etc. These kinds of competitions of contribute to the identification and development of interests, creative abilities of students, expansion of knowledge and outlook, activation of cognitive activity.

Repertorio biográfico de agrupaciones musicales de Rock & Roll, Nueva Ola, Beat y Rock Progresivo en la Argentina (1955-1973)
Authors: Luirette Carlos Daniel
Published: December 2022

La falta de obras de referencia que recopilen los primeros años del movimiento rock-pop en Argentina ha provocado la invisibilidad de gran parte de los músicos y grupos pioneros. La historiografía oficial ha dado escasa importancia a las producciones musicales anteriores a la grabación del tema “La Balsa” por Los Gatos en 1967, lo que motivó que gran parte de esa historia permaneciera oculta. En los últimos años numerosos estudios académicos han abordado esta problemática, dando una nueva mirada a la emergencia de los orígenes y afianzamiento del llamado Rock Nacional. Postulamos que la Bibliotecología mediante sus técnicas de búsqueda y acceso a la información, cumple un papel fundamental en la búsqueda y organización documental para poner luz sobre los inicios difusos del rock en la Argentina. Este proyecto individual (en curso) tiene como objetivo investigar dicho período, y generar un repertorio biográfico sobre el movimiento del rock/pop en la Argentina, recopilando a los solistas y bandas que surgieron entre 1955 y 1973 y que prefiguraron al futuro Rock Nacional.

Published: December 2022

Studies, about products obtained from agricultural wastes, have increased within the scope of zero waste studies . The olive pomace is produced as a result of olive oil production. In the present study, activated carbon was synthesized using the olive pomace taken from the olive pomace processing plant operating with a three-phase process. The synthesized activated carbon characterization was performed using Scanning Electron Microscope (SEM), Fourier-Transform Infrared Spectroscopy (FT-IR), Brunauer – Emmett – Teller (BET), and X-Ray Crystallography (XRD) devices. Olive pomace activated carbon (OPAC) was used for the adsorption of dye from an aqueous solution. The adsorption efficiency of the OPAC was investigated. The initial pH value of dye solution (6-9), the amount of activated carbon (0.5 and 1.0 g/L), and initial dye concentration (600-1200 mg/L) were optimized. Also, adsorption kinetic and isotherm calculations were evaluated. The optimum parameters were found as the original pH value (pH=8) of dye solutions, OPAC amount of 1.0 g/L and the initial concentration of 1000 mg/L. The Langmuir isotherm model and the pseudo-second-order kinetic model were found as the most suitable models. It can be said that the synthesized material can be used at dye removing from wastewater.

Comportamento de caça da coruja buraqueira, Athene cunicularia (Molina, 1782) (Aves: Strigiformes) em ambiente urbano em Belo Horizonte, Minas Gerais, Brasil

Published: December 2022

The burrowing-owl, Athene cunicularia (Molina, 1782) has a wide distribution, which extends from western North America to southern South America. They are an opportunistic plunderer species preying on insects and small mammals. Data on hunting tactics of this specie are scarce in the literature. Here, the general and hunting behaviors of the species are described in an urban environment, a university campus, in the city of Belo Horizonte, Minas Gerais state, Brazil. An adult male of A. cunicularia had its behavior studied during 14 days, in July 2005, totaling 20 hours of systematic observations using the instantaneous focal-animal method. The observations were done using 10x50 binoculars, between 06:00 and 09:00 and after 16:00, from a minimal distance of 25 m. We identified and described five behavioral categories: self-maintenance, locomotion, hunting, non-agonistic social and alert. No difference was found between behaviors displayed during morning and afternoon periods. Four hunting strategies displayed by A. cunicularia were identified (hunting in soil, air hunting, perch to soil hunting and hover flight hunting) but no difference between their frequencies was found. These behaviors were observed only after 18:00. These non-significant patterns suggest that the oportunistic hunting behavior of the birds of prey (“sit-and-wait”) and the active search hunting patterns are alternated according to opportunity, identification and capture of the prey and the place of capture.

Authors: Azuma Yuki , Kimura Shun , Gamo Hironori , Motohisa Junichi , Tomioka Katsuhiro
Published: December 2022

We characterized the current injection and electroluminescence (EL) properties of wurtzite (WZ) InP nanowire (NW) light-emitting diodes (LEDs) with axial junctions. The EL spectra of two samples with the same LED junction structure exhibited two different behaviors. One showed a single EL peak originating from the zinc-blende (ZB)-InP bandgap. The other showed two EL peaks originating from the ZB and WZ phases. This difference in EL behavior is attributed to the difference in the contact position and to depletion layer spreading. Clarification of the origin of the different EL peaks is important for optimizing the NW-LED structure.

Published: December 2022

Modal interference in a multimode fiber (MMF) has been utilized to develop simple sensors for various physical parameters. Herein, first, we investigate the dependences of the core diameter and the numerical aperture (NA) of the MMF on the performance of multimode-interference-based strain and temperature sensing. We find that a larger core diameter leads to higher temperature sensitivity but lower strain sensitivity (absolute value) and that higher NA does not influence the temperature sensitivity but results in higher strain sensitivity (absolute value). Subsequently, using the obtained low strain sensitivity, we demonstrate strain-insensitive temperature sensing with a sensitivity of approximately 6.1 pm °C−1.
DMD-based pure-phase superpixel method for digital holography
Authors: Xie Qian , Yu Song-Tao , Wang Xuan-Kai , Zheng Yong-Guang , Yuan Zhen-Sheng
Published: December 2022

In this work, we implement a pure-phase superpixel (PPSP) method with a digital micromirror device (DMD). Here the DMD acts in an unconventional mode, i.e. as a phase-only modulator with hundreds of phase levels. An iterative Fourier transform algorithm is adapted to the DMD with high quality in a 2f-configuration without filters. When using 1600 × 1600 DMD pixels, the simulations show that the PPSP method in combination with the mixed-region amplitude freedom algorithm reduces the root-mean-square error by at least 33.5% compared with the conventional amplitude and phase modulation methods, and provides higher efficiency by 7.3%.

Published: December 2022

Introduction: Pap stain is a universal stain which is used for cytological screening. It is a very reliable technique. There are certain limitations of
routine PAP staining like using of ethanol as dehydrating agent which is costly, hazardous and color preservation is not long standing. Our aim Aim:
was to design a method using a limited amount of ethyl alcohol and it had to be rapid and economical as standard Papanicolaou stain without
compromising staining quality. Materials And Merhods: A total of 200 smears collected from the endometrium of 100 unxed total hysterectomy
specimens, 2 smears from each specimen, received in Pathology department of S Nijalingappa Medical College, Bagalkot. Of these, 100 smears
underwent standardization of the Hazard free Pap staining and their counterparts underwent routine Papanicolaou staining. Results: The two
methods were compared in respect of staining quality, cytoplasmic, nuclear details, time, cost and its ecofriendly feature. Staining time was
minimized to 4 minutes from 20 minutes.In Hazard free staining, the nuclear and cytoplasmic staining was optimal in 90 and 93 respectively.
Conclusion: Hazard free Pap stain provides a suitable, excellent and rapid alternative for cytological screening with minimum cost, lesser time and
being ecofriendly by avoiding ethanol.
