Published: June 2023

A high-resolution simulation of CO2 at 1×1 km horizontal resolution
using the Weather Research and Forecasting Greenhouse gas (WRF-GHG)
model was conducted, focusing on the Kanto region in Japan. The WRF-GHG
simulations were performed using different anthropogenic emission
inventories: EAGrid (Japan, 1 km), EDGAR (0.1o), and EDGAR-downscaled
(0.01o). Our analysis showed that the simulations using EAGrid better
captured the diurnal variability in observed CO2 compared to EDGAR and
EDGAR-downscaled emissions at two continuous monitoring sites. The 1×1
km simulation performed better in simulating CO2 variability observed in
surface sites (hourly) and aircraft observations, compared to the 27×27
km simulations. We compared the vertical profile distribution of CO2 and
found that all the simulations performed similarly. During February
(May), the anthropogenic (land biosphere) fluxes were the primary
contributor to the vertical distribution of CO2 up to an altitude of
3200 m (4500 m), beyond which long-range transport influenced by lateral
boundary conditions from Eurasia played a greater role. The sensitivity
analysis of boundary conditions showed a systematic bias
(~ 4 ppm) persisting above 3200 m altitude when fixed (a
constant value) boundary conditions are applied, as compared to the
simulation with boundary conditions from a global model. We also
compared the WRF-GHG simulated column-averaged XCO2 from Orbiting Carbon
Observatory-2 (OCO-2) satellite and found a statistically significant
spatial correlation (r=0.47) in February. However, we found a weaker
spatial correlation (0.17) in May, which could be caused due to
under-representation of intense land biosphere activity in WRF-GHG.
Sub-mesoscale Wind-Front Interactions: the combined impact of thermal and current feedback
Authors: Bai Yue , Thompson Andrew F. , Bôas Ana Beatriz Villas , Klein Patrice , Torres Hector S. , Menemenlis Dimitris
Published: June 2023

Surface ocean temperature and velocity anomalies at meso- and
sub-meso-scales induce wind stress anomalies. These wind-front
interactions, referred to as thermal (TFB) and current (CFB) feedbacks,
respectively, have been studied in isolation at mesoscale, yet they have
rarely been considered in tandem. Here, we assess the combined influence
of TFB and CFB and their relative impact on surface wind stress
derivatives. Analyses are based on output from two regions of the
Southern Ocean in a 4-6 km-resolution coupled simulation. Considering
both TFB and CFB shows regimes of interference, which remain mostly
linear down to the simulation resolution. The jointly-generated wind
stress curl anomalies approach 10-5 N-3, ~20 times
stronger than at mesoscale. The synergy of both feedbacks improves the
ability to reconstruct wind stress curl magnitude and structure from
both surface vorticity and SST gradients by 12-37% on average, compared
with using either one alone.
Estimating the impact of a 2017 smoke plume on surface climate over northern Canada with a climate model, satellite retrievals, and weather forecasts

Published: June 2023

In August 2017, a smoke plume from wildfires in British Columbia and the
Northwest Territories recirculated and persisted over northern Canada
for over two weeks. We compared a full-factorial set of NASA Goddard
Institute for Space Studies ModelE simulations of the plume to satellite
retrievals of aerosol optical depth and carbon monoxide, finding that
ModelE performance was dependent on the model configuration, and more so
on the choice of injection height approach, aerosol scheme and biomass
burning emissions estimates than to the choice of horizontal winds for
nudging. In particular, ModelE simulations with free-tropospheric smoke
injection, a mass-based aerosol scheme and high fire NOx emissions led
to unrealistically high aerosol optical depth. Using paired simulations
with fire emissions excluded, we estimated that for 16 days over an 850
000 km2 region, the smoke decreased planetary boundary layer heights by
between 253 m and 547 m, decreased downward shortwave radiation by
between 52 Wm-2 and 172 Wm-2, and decreased surface temperature by
between 1.5 oC and 4.9 oC, the latter spanning an independent estimate
from operational weather forecasts of a 3.7 oC cooling. The strongest
surface climate effects were for ModelE configurations with more
detailed aerosol microphysics that led to a stronger first indirect
effect.
Transformation of Precursor Iron(III) Minerals in Diagenetic Fluids: Potential Origin of Gray Hematite at Vera Rubin Ridge
Authors: Knight Abigail L. , Mitra Kaushik , Catalano Jeffrey G.
Published: June 2023

Coarse-grained (> 3-5 µm) gray hematite particles occur at
Vera Rubin ridge (VRR) within Gale crater, Mars. VRR has likely
undergone multiple episodes of diagenesis, at least one of which
resulted in the formation of gray hematite. The precursor mineralogy and
nature of the diagenetic fluids that produced coarse-grained hematite
remain unknown. Analog laboratory experiments were performed on a
variety of iron(III) minerals to assess the potential fluid conditions
and precursor mineralogy that form coarse-grained hematite. Gray
hematite formed from the transformation of jarosite after 20 days at 200
ºC. Conversion was complete in chloride-rich fluids but substantial
jarosite remained in sulfate-rich fluids; no transformations of jarosite
occurred when aged at 98 °C. All other precursor minerals (akageneite,
ferrihydrite, goethite, and schwertmannite) did not transform or
produced only red, fine-grained hematite under all conditions assessed.
In addition, seeding precursor iron(III) phases with red hematite and
coarsening pre-existing red hematite both failed to produce gray
hematite. These results suggest that jarosite was the precursor of gray
hematite at VRR and the diagenetic fluids were low in sulfate and
potentially chloride-rich. Jarosite produces gray hematite because the
acidic conditions it generates yield both a low degree of hematite
supersaturation, producing few nuclei, and high dissolved iron
concentrations, enabling rapid hematite growth. Gray hematite readily
forms under oxic conditions and its occurrence at VRR is not a marker
for a redox interface. The associated diagenetic event was thus unlikely
to have generated substantial new chemical energy for life.

Authors: Puteri Dwi Ane Risqi , Ibrahim Nurdin , Priyono
Published: June 2023

The Civics learning process should be carried out interactively by choosing media to actively stimulate students to solve contextual problems. But the problem is that the learning process must focus on students. This study aimed to conduct a needs analysis to develop interactive learning videos for Civics subjects. This research was conducted using the R&D (Research & Development) method. The research subjects were eleventh-grade students, totaling 36 students—data collection methods by observation, interviews, and tests. In learning from home, students want media in the form of interactive learning videos. Interactive learning videos can be used for a more learner-centered learning process because they contain questions. The questions in the learning video are expected to make students actively listen and answer the learning material. From the analysis results, it was concluded that interactive learning videos are needed to help the learning process be more student-centered to have a positive impact, especially in creating an interactive learning process.

Published: June 2023

Evaluation of learning implementation is critical. The emphasis is mostly on polysynchronous learning. The purpose of this study is to assess polysynchronous learning of statistical material in high school. The type and approache  of this study is descriptive-quantitative. The subjects of the study were 29 high school students. Observation, tests, and questionnaires were used to collect data on the implementation of polysynchronous learning, problem-solving ability, and student learning independence. Data analysis is performed in three stages: scoring, computing percentages, and generating conclusions based on the provided categories. The results demonstrated that polysynchronous learning can be implemented properly utilizing Whatsapp for asynchronous and Google Meet for synchronous. Pupils with very high, high, medium, and low problem-solving talents are represented by 11, 7, 5, and 6 students, respectively. The number of pupils with learning independence ranges from very high to high to medium, with as many as 6, 19, and 4 students in each category. Students have the ability to solve mathematical problems and the independence to learn high-level categories, which makes it possible for the implementation of polysynchronous learning of statistical material to be carried out in an appropriate manner. The findings of this study suggest that educators can make use of polysynchronous learning to enhance the problem-solving abilities and independent learning capabilities of their pupils, regardless of whether they are living in a pandemic or new-normal environment.
The Effect of Mathematical Disposition on Basic Mathematical Abilities in the Online Learning
Authors: Setiawan Yayan Eryk , Surahmat
Published: June 2023

The problem that arises from online learning is decreased learning outcomes or low ability in mathematics. This problem can be overcome by looking for various variables in online learning. Researchers suspect that this mathematical disposition influences basic mathematical abilities. Thus, the purpose of this study was to analyze the effect of mathematical disposition on basic mathematical abilities in online learning. This type of research is quantitative research with a comparative causal approach. The sample of this research is 65 prospective mathematics teacher students at the Islamic University of Malang. The research data is in the form of the results of filling out the mathematical disposition questionnaire and the results of working on basic math skills questions. The research instrument consisted of a questionnaire and questions. The questionnaire and questions used have met valid and reliable criteria. The data analysis technique used in this study is a simple correlation and regression analysis with the help of SPSS. The results showed that mathematical disposition (self-confidence, creativity, persistence, curiosity, positive values, and respect) had a positive effect on basic mathematical abilities by 14.5%. From the research results, it can be concluded that the metaphysical disposition variable is positively correlated with the mathematical basic ability variable. The results of the study also show that mathematical disposition has a positive effect on basic mathematical abilities during online learning. The important mathematical disposition components to pay attention to during online learning are creativity, persistence, curiosity, positive value, and respect for mathematics. These components are the benchmarks for the influence of mathematical disposition on basic mathematical abilities.
Estudiantes de inglés de secundaria en el camino hacia la autonomía
Authors: Peralta-Castro Fernando
Published: June 2023

Después de revisar un extenso cuerpo de literatura sobre el aprendizaje autónomo, se hizo evidente que el concepto de autonomía en el aprendizaje de idiomas se usa a menudo junto con otros términos como autoinstrucción, aprendizaje independiente, autodirección y autorregulación. La evidencia existente también parece sugerir que convertirse en un estudiante autónomo no es algo sencillo. El objetivo de este estudio es investigar qué atributos del aprendizaje autónomo se pueden fomentar durante el proceso de enseñanza y aprendizaje de idiomas, en un contexto específico. Para ello, se diseñó e implementó un estudio de caso en una escuela pública del occidente de México, con la participación de dos maestros en formación y doce estudiantes de secundaria, estudiantes del idioma inglés de 12 a 14 años que asistieron a un curso no obligatorio de 40 horas bajo el enfoque de aprendizaje autónomo. Antes de esta experiencia, los alumnos solían aprender en entornos centrados en el profesor. Los docentes en formación escribieron un diario de investigación a través del cual documentaron todo el proceso y permitieron adquirir conocimientos sobre el aprendizaje autónomo y examinar el fenómeno en un contexto de la vida real. Los diarios se analizaron con la ayuda del software Atlas.ti, y el investigador hizo inferencias a partir de los datos resultantes, incluidas las reacciones de los alumnos al proceso de aprendizaje autónomo. El análisis de datos muestra cómo el comportamiento y la respuesta de los alumnos al curso de inglés fue, en su mayor parte, pasivo al principio, pero se acercó cada vez más al aprendizaje autónomo a medida que avanzaba el curso. En resumen, los datos parecen arrojar luz sobre dos cuestiones principales: la importancia de fomentar un entorno que fomente el comportamiento relacionado con el aprendizaje autónomo y la necesidad de proporcionar estrategias de andamiaje adecuadas para ayudar a los alumnos a avanzar hacia el desarrollo del aprendizaje autónomo. Este estudio permitió comprender que la autonomía es un camino a recorrer, más que el estado natural de un aprendiz, en este contexto educativo particular.

Published: June 2023

Sericulture is one of the non-timber forest products (NTFPs) that can help Indonesians live better lives and support environmental improvement. Silk, as a product of sericulture, is one of the five NTFPs that Indonesia has identified as having the ability to boost the nation’s economy and alleviate poverty. However, there are several issues with the development of silk in Indonesia, chiefly issues with the quality of silkworm seedlings and low cocoon yield. Crossbreeding is one method used to boost egg output. This study aimed to evaluate the eggs and cocoons produced by various silkworm (Bombyx mori L.) crosses. The Pustarhut Laboratory hosted the research from May to August 2022. Twelve treatments were employed in the form of crosses using the Randomized Block Design (RBD) method, and each treatment applied three replicates. Overall, the findings demonstrated that the CE cross ((919 x 927) x (804 x p208)) produced eggs (652 eggs) and cocoons of higher quality than other crossings. However, although the egg numbers of CF cross ((919 × 927) × (p208 × 804)) and FC cross ((p208 × 804) × (919 × 927)) produced 622 and 631 eggs, respectively and were significantly different from CE cross, they still produced egg numbers above 600. In addition, they produced cocoon quality that was not significantly different from CE cross. All finding indicates that silkworms from CE, CF, and FC crosses can be used as an alternative to superior silkworm breeding to increase the productivity of silkworm rearing in Indonesia.

Authors: Iswandaru Dian , Hariyono  , Rohman Fathur
Published: June 2023

The development of avitourism in villages around the conservation area still needs optimal support to increase welfare and reduce illegal practices like bird hunting. Birds are wild animals that play an essential role in the ecosystem. One of the efforts that have been developed in the buffer village to improve the welfare community and the conservation of birds is avitourism. This study aimed to analyze birds that have the potential as objects and attractions in avitourism. The bird species recorded were 82 species from 39 families. The results of key informants’ perception analysis revealed that 55 bird species (67.07%) have the potential as objects and attractions of avitourism, showing the nocturnal birds, top 50 birds of Way Kambas National Park, and parrot species as the top classification (> 75%). The colorful, raptor, and protected criteria are second with the favorite classification (51-75%). Endemic and migrant criteria are in the third position with the impressive classification (25-50%), and the songbird criteria are the lowest with the interesting classification (< 25%). The existence of birds that have the potential as objects and attraction of avitourism in the villages around Way Kambas National Park indicates that areas can be used in locations for avitourism, including bird photography, to improve welfare.

6.- ja 7. -luokkalaisten informaatiokäyttäytyminen harrastuneisuudessa
Authors: Koho Tuomo
Published: June 2023

Tutkimus selvittää suomalaisten lasten ja nuorten harrastuneisuudessa ilmenevää informaatiokäyttäytymistä keskittyen sosiaaliseen mediaan. Aikaisemmat tutkimukset ovat osoittaneet, että nuoret integroivat teknologiaa vapaa-aikaansa, myös harrastuksiinsa, yhä kasvavissa määrin. Tämä tutkimus osoittaa kuudesluokkalaisten ja seitsemäsluokkalaisten eroja harrastus- ja teknologiakäyttäytymisessä, tutkii teknologian integrointia eri harrastuksiin sekä eri harrastemuotojen välisiä yhteyksiä. Tulokset osoittavat, että erityisesti luovat harrastukset (esimerkiksi kuvataide, kuvaaminen, kirjoittaminen ja musiikki) ovat yhteydessä toisiinsa ja että tietokonepelaaminen rajoittaa muuta harrastelua. Lisäksi 12- ja 13-vuotiaiden sosiaalisen median käyttö on vielä melko vähäistä, mutta vaikuttaa kasvavan iän myötä. Sosiaalisen median sovellukset kuitenkin korreloivat useiden harrasteiden kanssa.
 
Information behaviour in leisure time activities among 6th and 7th graders
Abstract
This pilot study explores the information behaviour, more specifically the use of social media, occurring in the leisure time activities of Finnish children and adolescents. It highlights leisure time activities as well as information behaviour in leisure time activities. Earlier studies have shown that young people integrate technology into their leisure time elements, including hobbies, with an increasing rate. This study illuminates differences between 6th and 7th graders in both their leisure time activities as well as in their information behaviour related to these activities, demonstrates the integration of information technology to leisure time activities and portrays correlations between leisure time activities. The results illustrate, for example, that there is a correlation between creative activities (such as arts, photography, writing and music), and that computer gaming hinders participation in other leisure time activities. In addition, twelve- and thirteen-year-olds do not seem to use social media markedly although the usage is increasing with older participants. Social media applications do, however, correlate with various leisure time activities.

Cycloactivism in Mexico City
Authors: Acosta García Raúl
Published: June 2023

Cycling in Mexico City is dangerous. But over the last two decades it has become less so. New cycleways, a large public bicycle-sharing scheme, various government cycling promotion projects and an abundance of official signalling demanding respect for cyclists have made bicycles visible as worthy vehicles on city streets. For cycloactivists, however, such improvements are not enough. Cyclists are frequently harassed, attacked or run over by motorists. Cycloactivists thus demand more and better cycleways as well as increased measures to address injustices in mobility issues across the city. They do so through protests, information campaigns, public performances and academic debates, and crucially, by cycling through city streets. This means that they use their bodies as symbols, to highlight their vulnerability. Along the way, they often break existing traffic rules to highlight how unfair they are and to draw attention to other demands. I refer to their efforts as experiential cycloactivism, which highlights cyclists making themselves vulnerable as a means of denouncing illegitimate rules and policies that need to be changed. I conclude the analysis by suggesting that their style of rule-breaking is a type of ritual with which they seek to improve the city, not burn it down.
Fight for Better Rules
Authors: Hertz Ellen
Published: June 2023

Rules are a basic property of human societies and yet they occupy a historically contested place in the modern narrative about what makes us human. Rules are infinitely malleable and ambivalent, at the same time a reflection of power inequities, a mechanism for reinforcing these inequities and a means to challenge them. Transgressing them can both create new spaces of freedom and reinforce the norms that they seek to establish. Reframing rules as potentialities helps break this spell. It allows us to ask not what we should do but what we can do, and to take the measure of the limits of our actions, as humans and as social scientists.

Evaluating the Efficacy of Green Tea and Chlorhexidine Mouthwashes in Relieving Post-extraction Complications like Pain and Hemorrhage
Authors: Wahidujjaman  , Habibullah AKM , Hasan Mahmudul , Hossain Mozammal
Published: June 2023

This cross-sectional observational study aimed to evaluate the effectiveness of green tea and chlorhexidine mouthwashes in reducing post-extraction complications such as pain and bleeding. The studied sample consisted of 80 people with an average age of 43.67 (±4.78) years. Tooth extraction is shown to all participants. After the tooth extraction, the green tea group was advised to bite the pictures of the gauge into the green tea, take a bite, and rinse their mouths with green tea mouthwash the next day. Subjects with another group bite soaked in chlorhexidine saline solution after tooth extraction and chlorhexidine mouthwash. Operation time, hemostasis time, VAS pain after tooth extraction and total number of analgesics were recorded. Descriptive statistics were calculated and chi-square t-tests and independent samples were performed using SPSS 22. The results showed that there was no significant difference in age, sex, and time of surgery between the two groups. The mean VAS was significantly lower in the green tea group compared to the chlorhexidine group. In addition, the green tea group also showed a shorter time for complete hemostasis and less analgesic consumption than the chlorhexidine group. It can be concluded that green tea is significantly effective in reducing the time of complete hemostasis and pain after tooth extraction. Thus, by conducting additional studies, green tea can be found to be therapeutically useful for the treatment of post-extraction bleeding and pain.
The Sun and the Moon on the Plaques of Mithras
Authors: Persoons Dominique J.
Published: June 2023

The representations of Mithras are the object of a true fascination by the historians and the researchers. The challenge is serious, since there are almost no documents on this religion, except indirect testimonies. However, it was more important than Christianity for 4 centuries. Its installation in Rome seems to be contemporary with Christianity and linked to the person of Flavius Josephus. Many academic theories have tried to make Mithraism an anti-Roman oriental religion, but this hypothesis seems paradoxical, since it was practised by the army of Rome and its high officials. Others see in the stars a universal religion with a cosmic salvation, a novelty for the time, but one wonders why it was elitist and masculine. Others see, in the Sun/Moon opposition, the challenge between the East and the West of the Empire, but does this opposition of two luminaries date from the century of Augustus? Finally, others have seen in the sacrifice of the bull a Stoic philosophy. But can a philosophy become a religion with Mysteries?

Urban forests are one of the natural ecosystems in urban environments. One of the most important components of the urban forest ecosystem is the understory shrubs. Therefore, this study aims to estimate the diversity of understory shrubs in the Srengseng Urban Forest in Jakarta City. The biodiversity of understory shrubs is calculated using the Shannon-Wiener diversity index (H') and mapped using the Geographic Information System (GIS). In this study, 24 plots measuring 2 m by 2 m each were placed to survey the understory shrubs. In total, there were 20 species of shrubs identified, which belong to 12 families with average values of H' is 0.671. The results show that almost 62.78% of the total Srengseng Urban Forest area has a H' diversity range of 1.001–1.500. In comparison, 8.62% of total urban forest area has an H' diversity range of 0.501-1.000. The area of urban forest with the lowest diversity in the H' diversity range of 0.000 to 0.500 reaches 28.58%. The eastern parts of the urban forest have the highest H' in comparison to the other parts of the forest. This study contributes to the conservation and forestry management of forest at an urban scale by identifying parts of the urban forest that should be conserved in the Srengseng. To conclude, the eastern parts of Srengseng Urban Forest sizing 64,765 m2 should be prioritized for understory shrub conservation.
Nickel acquisition affected by root density of mono- and mixed-cropping peanut and choy sum

Published: June 2023

Nickel (Ni) and associated minerals (Cr and Mn) are naturally occurring substances in ultramafic laterites soil. It may be found in our vegetables and grains when agriculture is grown in ultramafic laterites. This study aimed to assess the contamination of Ni in edible crops affected by soil volume in mono- and mixed cropping on limonitic laterite soil. The investigation was conducted on Peanut (Arachis hypogaea L.) and Choy Sum (Brassica rapa var. parachinensis) in three different pots sizes-representing soil volume to support root growth, which was filled with 0.5 kg (small), 1.0 kg (medium), and 1.5 kg (big) of limonitic laterite soil, respectively. The limonitic soil has a 7.884 mg kg-1 Ni concentration. The experiment shows that Ni concentration in peanut and Choy Sum shoots of mono-cropping in small, medium, and big pots achieve 20, 90, 120 mg kg-1 and 51, 67, and 95 mg kg-1, respectively. Meanwhile, in mixed cropping, Ni concentration in small, medium, and big pots of peanut and Choy Sum shoots are lower only by 33, 50, and 51 mg kg-1 and 15, 52, and 63 mg kg-1, respectively. Contamination of Ni in Peanut and Choy Sum shoots increases with the increasing soil volume, and mixed cropping is a potential strategy to reduce the acquisition of Ni.

The Editorial Board has issued this editorial note in the form of a review to inform contributors about changes to the scope of the Journal of Wallacea Forestry Research (JPK Wallacea) following the transfer of management from Balai Penerapan Instrumen Lingkungan Hidup dan Kehutanan Makassar to Hasanuddin University's Forest Conservation Study Program in 2023. JPK Wallacea is no longer limiting its scope to forestry and is expanded to cover biodiversity in general by incorporating the term Wallaceae, which is a biogeographical area located between the continents of Asia and Australia. This area is well known for its unique biodiversity both on land and in water. The Wallacea region's biodiversity is famed for its distinctiveness yet, it is on the verge of extinction. Thus, the Editorial Board chose to focus on the scope of JPK Wallacea on scientific, technological, and policy conservation features. This scientific publication is expected to make a substantial contribution to the biodiversity conservation effort in the Wallacea region and its surroundings.

Published: June 2023

The key of the success of the neonicotinoid-type insecticides is that they have the greatest affinity to the nicotinic acetylcholine receptors of the insect central nervous system. They block them irreversibly, eventually, they cause the destruction of pests insects. Ultimately, they affect the healthy functioning of ecosystems: their effect also can be extended to plant visitor pollinators – bees, butterflies, hoverflies, etc. –, causing poisoning-, health- and behaviour-changing symptoms. In 2013, we investigated the effect of the residues of a neonicotinoid seed treatment of sunflower's among semi-field conditions More than 19 000 died individuals were collected during the measurements. On the basis of the results it can be stated that the literature known symptoms required about two weeks to appear on bees. The result have underlined the relevancy of our examinations to interrelation of beekeeping and modern crop systems.

Published: June 2023

In this study, types of the intermolecular interactions, the intermolecular interaction energies, void analysis of diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)zinc(II) dihydrate (Complex 1), diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)nickel(II) dihydrate (Complex 2), diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)cobalt(II) dihydrate (Complex 3), whose crystal structures were characterized before, were investigated with the help of the CrystalExplorer program (Version 21.5). It has been determined that H…H, H…O/O…H, H…C/C…H, H…N/N…H, C…C, C…O/O…C, O…O, and C…N/N…C interactions are intermolecular interactions that contribute to the Hirshfeld surface of the complexes. According to the results of the interaction energy analysis calculated with the help of B3LYP/6-31G(d,p), B3LYP/6-31G(d), B3LYP/3-21G, HF/6-31G(d,p), HF/6-31G(d), HF/3-21G, DFT/6-31G(d,p), DFT/6-31G(d), DFT/3-21G, MP2/6-31G(d,p), MP2/6-31G(d), MP2/3-21G basis sets, the major amount of the total energy is contributed by electrostatic and polarization energies. The interactions between Complexes 1-3 and the main protease enzyme and the spike protein of Omicron variant of the SARS-CoV-2 were investigated by Molecular docking studies. It was determined that complexes 1-3 and the main protease enzyme and the spike protein of Omicron variant of the SARS-CoV-2 interact via attractive charges, hydrogen bonding, electrostatic contacts, and hydrophobic interactions. According to the obtained results, further in vivo/in vitro studies are recommended for complex 3. The results determined as a result of interaction energy analysis and molecular docking studies show that the hydrogen bonds formed by the hydrogen bond donor/acceptor groups in the structure of the complexes are an important factor in both the stability of the crystal package and inhibition of important enzymes of SARS CoV-2.

Published: June 2023

In this work, traveling wave solutions of (1+1)-dimensional Landau-Ginzburg-Higgs and Duffing nonlinear partial differential equations, which are examples of mathematical modeling, are obtained and analyzed using the modified exponential function method. In order to facilitate the physical interpretation of the mathematical models represented by these equations, simulations of the behavior of the mathematical model as three-dimensional, contour, density and two-dimensional graphics are given using a package program with the help of appropriate parameters. It has been shown that the modified exponential function method effectively investigates the solutions of (1+1)-dimensional Landau-Ginzburg-Higgs and Duffing equations.
