Published: June 2023

The increasing number of vehicles in the world and the increase in the dimensions of light and heavy vehicles with different combinations, including simple and compound axles, have caused various types of damage in the asphalt, which affects the performance of the roads and requires a suitable pavement. For this reason, engineers try to improve the performance of asphalt mixture in different ways and increase their useful life. Cracking is one of the main failure modes of asphalt pavements. Fatigue cracking is the most common form of asphalt failure and is one of the important factors in reducing the life of road pavements. The purpose of this research is to investigate the index of self-healing potential (HI) of asphalt mixtures containing activated carbon and zycotherm by induction heating method and modelling by artificial neural network. First, by making warm mixture asphalt samples containing activated carbon, self-healing by induction heating method was provided in the pavement, and then the effect of traffic loading and environmental conditions simultaneously in terms of changes in loading parameters, taking into account the conditions of the service life. The results show that the use of activated carbon increases the values of shear modulus. It also improves the properties of modified bitumen at all temperatures. The resistance of the asphalt mixture against breaking and cracking, as well as the maximum force tolerance at the temperature of -16°C is higher than at the temperature of 25°C, which is one of the reasons for the reduction of flexibility of bitumen at low temperature. Also, for modelling, perceptron multi-layer neural network (MLP) with 9 input variables, three hidden layers and one output layer has been used. The results showed that the explanation coefficient of the neural network model for training, validation and evaluation data was 0.99717 for training, 0.62053 for validation and 0.9301 for testing. These values correctly show the high fitting ability of the proposed neural network model. Also, the lowest value obtained for the mean squared error is 4.9223x10^(-5) and in epoch 14.
A Study on the Production Performance of a Horizontal Shale Gas Well Using a Fully Coupled Flow and Geomechanics Modeling
Authors: Tareq Mohammed Al-Shami  , Shiferaw Regassa Jufar  , Mohammed Bashir Abdullahi  , Berihun Mamo Negash
Published: June 2023

Conventional petroleum reservoir simulators use constant rock compressibility to denote rock deformation. However, due to the stress-sensitive nature of the shale formations, using constant rock compressibility in reservoir simulators does not accurately capture the pressure diffusion in the reservoir, leading to a higher error margin in flow rate estimation. Fluid flow coupling with geomechanics is used to account for such a phenomenon numerically. Such an approach is important for shale numerical studies and any energy underground storage modeling (i.e., CO2 storage). Usually, when fluid flow coupling with geomechanics is studied for shale formations, the fluid, and the stimulated reservoir petrophysical properties are overlooked. This paper aims to present a study on the effect of the fluid and reservoir petrophysical properties on the performance of a gas-producing well. In addition, the results from the cases when geomechanics is coupled and decoupled with fluid flow in reservoir simulations are compared. The governing equations were discretized using the Finite Element Method. First, the model was validated against Terzaghi's consolidation theory analytical solution. After that, a history matching for the production flow rate was performed using field production data from Barnett Shale. Then a sensitivity analysis was carried out for the gas viscosity, Stimulated Reservoir Volume (SRV) porosity, and fracture conductivity. Next, the sensitivity analysis was conducted for the coupled and decoupled cases. Finally, the sensitivity analysis results were compared between the coupled and decoupled cases. The results show that lower gas viscosity, higher SRV porosity, and higher fracture conductivity improved horizontal well production performance. In addition, when the geomechanical effects were decoupled, the reservoir simulator overestimated the production flow rate and cumulative production.

This article is devoted to vocabulary expansion for students of a non-linguistic institution in the framework of English for specific purposes. Vocabulary learning is one the most important, difficult, time and effort-consuming tasks in language learning. The authors justify the need to form L2 learners’ vocabulary as the basis for their vocational proficiency, paying attention to more extensive learning of the word, including the word origin, its collocations and constraints on use. Academic Word List words are taken as research material. The authors consider four main types of words found in specialized texts, vocabulary level tests, as well as the range of aspects of receptive knowledgeof a word. It has been experimentally proved that both visual representation of a word with its form, meaning and use and a consistent repetition of a word in the classroom enable a word acquisition. Presentation slides are chosen as a means of facilitating visualization of the words. In conclusion, the authors show the importance of students' regular approach to their vocabulary expansion.

Rotation Reduces Convective Mixing in Jupiter and Other Gas Giants
Authors: Fuentes J. R. , Anders Evan H. , Cumming Andrew , Hindman Bradley W.
Published: June 2023

Recent measurements of Jupiter’s gravitational moments by the Juno spacecraft and seismology of Saturn’s rings suggest that the primordial composition gradients in the deep interior of these planets have persisted since their formation. One possible explanation is the presence of a double-diffusive staircase below the planet’s outer convection zone, which inhibits mixing across the deeper layers. However, hydrodynamic simulations have shown that these staircases are not long-lasting and can be disrupted by overshooting convection. In this Letter, we suggests that planetary rotation could be another factor for the longevity of primordial composition gradients. Using rotational mixing-length theory and 3D hydrodynamic simulations, we demonstrate that rotation significantly reduces both the convective velocity and the mixing of primordial composition gradients. In particular, for Jovian conditions at t ∼ 108 yr after formation, rotation reduces the convective velocity by a factor of 6, and in turn, the kinetic energy flux available for mixing gets reduced by a factor of 63 ∼ 200. This leads to an entrainment timescale that is more than 2 orders of magnitude longer than without rotation. We encourage future hydrodynamic models of Jupiter and other gas giants to include rapid rotation because the decrease in the mixing efficiency could explain why Jupiter and Saturn are not fully mixed.
A Shallow-water Model Exploration of Atmospheric Circulation on Sub-Neptunes: Effects of Radiative Forcing and Rotation Period
Authors: Landgren Ekaterina , Nadeau Alice , Lewis Nikole , Kataria Tiffany , Hitchcock Peter
Published: June 2023

Sub-Neptune-type exoplanets are abundant in our Galaxy yet have no solar system analogs. They exist in a broad range of stellar forcing and rotational regimes that are distinctly different from solar system planets and more commonly studied hot Jupiters. Here we present simulations that explore global atmospheric circulation of sub-Neptunes generated with a two-dimensional shallow-water model, SWAMPE. We explore the circulation regimes of synchronously rotating sub-Neptunes with a focus on the interaction of planetary rotation rate and radiative timescale in a variety of stellar insolations. In highly irradiated, short-timescale regimes, our models exhibit high day–night geopotential contrasts. As the timescales become longer, the geopotential contrasts and longitudinal variability decrease, while temporal variability increases. The transition from day-to-night flow to jet-dominated flow is primarily driven by the radiative timescale. Strong- and medium-forcing regimes exhibit transitions between day-to-night flow and jet-dominated flow at similar points in the parameter space. The weak-forcing regime differs owing to comparatively stronger rotational effects. Planetary rotation period dominates in determining equator-to-pole geopotential contrast. Our simulations exhibit higher time variability when either radiative timescale or rotation period is long.

Observations made by Earth-based radar telescopes and the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft provided compelling evidence for water ice in Mercury's polar craters. In our investigation, we constructed higher-resolution (125 m pixel−1) digital elevation models (DEMs) for four of the largest northernmost craters, Kandinsky, Tolkien, Chesterton, and Tryggvadóttir. The DEMs were leveraged to model solar illumination and the thermal environment, products that were used to identify permanently shadowed regions and simulate surface temperatures. From these models, we predicted the regions of surface stability for ice and volatile organic compounds. These predictions were then compared against the Arecibo radar, Mercury Laser Altimeter (MLA), and Mercury Dual Imaging System (MDIS) data. Our radar analysis shows that areas of high radar backscatter are correlated with areas predicted to host surface ice. Additionally, we identify radar backscatter heterogeneities within the deposits that could be associated with variations in ice purity, mantling of the ice, or ice abundances. The MDIS analysis did not reveal conclusive evidence for ice or volatiles at the surface, while MLA results support the presence of water ice at the surface in these craters. However, evidence for boundaries between the surface ice and low-reflectance volatile organic compounds, as suggested could be present by our models, was inconclusive owing to the limited MESSENGER data in these regions. BepiColombo’s upcoming orbital mission at Mercury has the opportunity to obtain new measurements of these high-latitude craters and test our predictions for the distribution of surface volatiles in these environments.
Distribution and diversity of fishes and lampreys in Transylvania (Romania): a complete survey and suggestions for new protected areas

Published: June 2023

Freshwater fishes are in a serious state of decline across the world, making them one of the most threatened groups of vertebrates. The Danube River catchment area in Europe holds the richest freshwater fish community, but our knowledge of the current distribution of these species is limited. Transylvania, the largest region of Romania, is one of the important tributaries of the Danube, from where 77 fish and two lamprey species were recorded until now. Despite this large diversity of freshwater fishes, there is a lack of systematic survey of the fish fauna in this region for the past 50 years. In this study, we present data on the occurrence and distribution of fishes and lampreys collected in Transylvania from 2007 to 2022. This data covers 43% of Romania’s surface and includes all major rivers from Transylvania. 65 species of fish and three species of lampreys are recorded, and an additional nine fish species are also reported based on information from competent people. Of the 77 fish and lamprey species recorded 19 (24.7%) are non-native, although their relative abundance was low (5.1%) compared to other similar regions in Europe. The first records of Eudontomyzon mariae, Neogobius melanostomus, Piaractus brachypomus, Pygocentrus nattereri, and Salvelinus alpinus in Transylvanian rivers are presented, as well as the first record of Cobitis elongata outside the Nera River basin (from the Caraș River) and the detection of three new populations of the vulnerable Umbra krameri. Data on changes in distribution that have occurred since the last comprehensive survey 50 years ago are also provided and the importance of our results in conservation planning are discussed, including the designation of new protected areas for freshwater bodies and the compilation of the Romanian Red List of fishes.
Split-step quintic B-spline collocation methods for nonlinear Schrödinger equations
Authors: Wang Shanshan
Published: June 2023

Split-step quintic B-spline collocation (SS5BC) methods are constructed for nonlinear Schrödinger equations in one, two and three dimensions in this paper. For high dimensions, new notations are introduced, which make the schemes more concise and achievable. The solvability, conservation and linear stability are discussed for the proposed methods. Numerical tests are carried out, and the present schemes are numerically verified to be convergent with second-order in time and fourth-order in space. The conserved quantity is also computed which agrees with the exact one. And solitary waves in one, two and three dimensions are simulated numerically which coincide with the exact ones. The SS5BC scheme is compared with the split-step cubic B-spline collocation (SS3BC) method in the numerical tests, and the former scheme is more efficient than the later one. Finally, the SS5BC scheme is also applied to compute Bose-Einstein condensates.
Analysis of a heterogeneous SEIRS patch model with asymmetric mobility kernel
Authors: Yin Shuangshuang , Wu Jianhong , Song Pengfei
Published: June 2023

In this paper, we establish a spatial heterogeneous SEIRS patch model with asymmetric mobility kernel. The basic reproduction ratio $ \mathcal{R}_{0} $ is defined, and threshold-type results on global dynamics are investigated in terms of $ \mathcal{R}_{0} $. In certain cases, the monotonicity of $ \mathcal{R}_{0} $ with respect to the heterogeneous diffusion coefficients is established, but this is not true in all cases. Finally, when the diffusion rate of susceptible individuals approaches zero, the long-term behavior of the endemic equilibrium is explored. In contrast to most prior studies, which focused primarily on the mobility of susceptible and symptomatic infected individuals, our findings indicate the significance of the mobility of exposed and recovered persons in disease dynamics.
A novel Internet of Things-supported intelligent education management system implemented via collaboration of knowledge and data
Authors: Wei Wenzheng , Jin Ying
Published: June 2023

The past decade has witnessed great progress in the Internet of Things (IoT), which can provide integrated platforms for data with various formats and to serve different parts of human society. Although IoT-supported education management systems have achieved some successful applications, most existing systems cannot perform intelligent information processing, such as autonomous planning and optimal scheduling. To remedy this gap, this work proposes a novel IoT-supported intelligent education management system that is implemented via collaboration of knowledge and data. First, the macroscopic architecture is designed according to field knowledge of education management, and a clustering-based data analysis algorithm is utilized to visualize real-time classroom characteristics. Then, statistics of learning status are generated, and personalized following plans are accordingly suggested to different specific users. Finally, the functions of the designed smart education management system are tested via computer simulation operations. The obtained results show that the proposal can work well under a real-time data stream and is expected to serve as a typical education management application in smart cities. Through verification, it is found that the integration of general education and professional courses is the ideal starting point for the design of the elements of an optimal course structure for engineering practice majors. In particular, we should strengthen the reform of the following course types: introduction to design, general education, concentrated practice, comprehensive design and peak courses.
Modulation of essential fatty acid levels in coconut oil with flaxseed oil
Authors: Joshi A.A. , Hegde M.V. , Zanwar A.A.
Published: June 2023

Coconut oil (CO) is a popular cooking medium but its lack of essential fatty acids (FA) is a health concern. Therefore, the aim of this work was to improve the FA profile of CO by blending with flaxseed oil (FO). Blends with various percentages of FO were prepared and studied for physicochemical characterization, thermal and long-term storage stability. The results indicated that the blends made favorable alterations in FA composition without adverse effects to the oxidative stability of the fatty acids and they resisted secondary thermal deterioration up to two hours at 180 ºC. The blend with the highest percentage of FO was stable for nine months. THP-1 cell line studies showed that ω-3 FA from the blend was incorporated into the cells with no adverse effect on cell viability but the inflammatory markers studied remained unaltered. Thus, CO and FO blends could be stored for at least nine months and could be used as cooking medium when prolonged heating is not involved.

Published: June 2023

Abstract— Augmented Reality is an emerging technology that holds vast potential for being used in pedagogy. The underlying technology of AR is becoming cheaper and ubiquitous every day as smartphones and tablets flood our markets. Numerous AR applications have been designed and developed for Android and IOS platforms to teach STEM subjects. The complexity and scope of such applications ranges from primary education to university education. Such applications have been developed in the developed and developing countries alike, however, there is still a need for such applications in Kazakhstan. This systematic literature review looked at developed Augmented Reality applications for teaching STEM subjects to High School children to develop a pathway for developing indigenous AR applications at the same scale. We identified a lack of standardize assessment tool for measuring success of AR studies. The results of the systematic literature suggest that Kazakhstani developers will need to focus on reducing technostress on children. Otherwise, the intended results may not be achieved as stress is counterproductive.
Introduction - Re-Assembling the History of Meridian Circles
Authors: Belteki Daniel , Gressot Julien
Published: June 2023

Meridian circles were tools of science, state and empire. Besides being used for astronomical observations, the by-products of observations made also had more utilitarian purposes applicable to commerce, transportation, industry and the expansion of empires. While meridian circles were created with the aim of producing spatial and temporal uniformity, observatories adopted different assemblages and configurations for their instruments. This issue brings together for the first time a variety of contributions to explore the material and social history of meridian circles. It deploys the concept assemblage to connect the different historical approaches together and to re-assemble the long history of the instrument.
The Crimes of Astronomical Instruments and Their Panopticon at the Royal Observatory, Greenwich during the Middle of the Nineteenth Century
Authors: Belteki Daniel
Published: June 2023

Simon Newcomb argued that nineteenth century observatory practices were dominated by the German school of practical astronomy devised by Friedrich Wilhelm Bessel. A key tenet of this school was the mathematical correction of instrumental errors. This paper argues that this mathematical maintenance created an approach whereby instruments were seen as criminals always deviating from their ideal operations. The paper takes as its case study the Airy Transit Circle at the Royal Observatory, Greenwich to demonstrate how the mathematical maintenance worked in action. The paper further argues that such an approach numerically disassembles and reassembles transit circles, while at the same time extending its components to include even the air and the soil surrounding it.
Les vies successives du cercle méridien portatif de Rigaud n° 2
Authors: Soulu Frédéric
Published: June 2023

Au milieu du xixe siècle, la lunette méridienne portative émerge pour mesurer la position sur terre ou déterminer l’heure. Le caractère de mobilité de l’instrument ne remet-il pas en cause en permanence l’état de stabilité de fonctionnement lentement obtenu pour la précision de la mesure ? Nous examinons cette question à travers le parcours du cercle méridien n° 2 de Rigaud. Utilisé au service de la révision des longitudes de la Carte de France par l’astronome Antoine Yvon Villarceau (1813-1883), il est détruit lors des évènements de la Commune. Restauré car nimbé d’une aura de précision, il sert dès lors dans plusieurs expéditions astronomiques de la fin du xixe siècle, dont certaines à vocation impériale. Prêté à l’observatoire jésuite de Madagascar, il en devient l’instrument méridien fixe dans le premier quart du xxe siècle.
