Authors: Cambiaso Sonia , Tagliabue Andrea , Bochicchio Davide , Tinti Antonio , Rasera Figueiredo Fabio , Giacomello Alberto , Monticelli Luca , Rossi Giulia
Published: November 2024

The MARTINI force field has become increasingly popular in material science by virtue of its versatility and its building block approach. However, force field parametrization is primarily based on reproducing structural and thermodynamic properties of the building blocks in solution, which may not be the most suitable strategy for regular, extended surfaces at solid-liquid interfaces, e.g., the planar facets of nanoparticles. In this study, we propose a novel strategy for parametrizing MARTINI planar surfaces in contact with liquids. While the choice of bead types in MARTINI models for molecules and ions in solution is often dictated by their chemistry, we suggest that surface-liquid interactions can be refined through a top-down approach. Specifically, we propose tuning the density of particles in the model surface to reproduce available experimental data on contact angles. In addition, we suggest several possible solutions to mitigate an artifact of the force field, that is, the excessive ordering of the liquid in contact with regular surfaces. Our findings demonstrate that water ordering can be reduced by tuning surface roughness and the level of coarse-graining of water. Eventually, we validate our approach on silica surfaces functionalized by alkyl chains.

Published: November 2024

The computational prediction of equilibrium constants is still an open problem for a wide variety of relevant chemical systems. Particularly, acid dissociation constants (pKa) are an essential asset in biological, synthetic or industrial chemistry whose prediction encounters several difficulties, requiring the development of novel strategies. The self-assembly of polyoxometalates (POMs) is another complex problem where acid-base reactions play a central role; a successful prediction of the formation constants of these structures is intimately linked with the limitations of pKa determination. Our methodology POMSimulator enables the prediction of these polyoxometalates formation constants from Density Functional Theory (DFT) calculations, using the experimental Kf values available in the literature to fit the resulting predictions. In this work, we carry out a systematic analysis of a very large number of POM formation constants already predicted through the application of POMSimulator. We then propose an universal scaling scheme for the adjustment of the DFT-based formation constants of POMs, relying on a linear scaling of the form y = mx + b. Here, the slope (m) is a constant parameter - hence, universal towards the nature of the polyoxometalate and the calculation method. The intercept (b), in contrast, is a system-dependent parameter that can be predicted with a multi-linear regression model trained with statistical aggregates of the non-scaled formation constants. Thus, we are able to successfully predict the speciation and phase diagrams of POM systems for which available experimental data is minimal, as well as providing a general scaling scheme that might be extended to other kinds of chemical systems.

Authors: Krishna Siri , S Pai Vinaya , Thomas Abraham , M Swetha , Kshetrimayum Nillachandra
Published: November 2024

Background and objectives This finite element study was conducted to calculate the distribution of stresses on root surfaces when an orthodontic force of 2N was applied at different degrees namely 0 30 and 45 degrees to the horizontal plane.Methods An in-vitro finite element method was used to construct a three dimensional finite element model of a mandibular arch without first premolars according to values given by Wheelers standard dental anatomy book using ANSYS 12 finite element software. Mechanical properties like Youngs modulus of elasticity and Poissons ratio were assigned to the model. To this model an orthodontic force was applied at various degrees on the crown of the tooth model. After the application of the forces initial stress on the root surface of mandibular anterior teeth was evaluated.Results The greatest amount of the maximum level of stress was found at the cervical margin of the PDL of all the tooth roots while the maximum stresses was highest at the root crest region of the canine. Bodily movement and tipping forces produce stress concentrated at the alveolar crest and not at the root apex.Interpretation and conclusion Clinical implications of this study suggested that if the clinician is concerned about placing an implant as anchorage for sliding mechanics to close dental arch spacethere is the same risk of root resorption after loading of force of 2N at 0 30 and 45 degree from the horizontal level.

The forest is an important human habitat. Monitoring forestry is essential to sustain life on Earth. Monitoring can be carried out using both Earth remote sensing methods and ground-based survey methods. The purpose of this article is to describe a methodology for studying the possibility of using mobile laser scanners to form a three-dimensional measurement scene on a circular test area of constant radius. The latter contains digital models of the terrain within its borders. A three-dimensional measurement scene is the optimal basis for constructing a digital twin of a forest ecosystem. Specialists are usually forced to count trees manually. Laser scanners allow not only to increase the accuracy of determining taxation characteristics, but also to generate cartographic materials, such as a tree plan. One of the trial areas with a pure pine plantation in the Bryansk region was chosen as the study area. To improve accuracy, the survey was carried out three times. Tree recognition and cataloging was then carried out. The measurement results were imported into a geographic information system, which made it possible to produce a tree-by-tree plan using standard geographic information modeling tools. As a result of the study, a technique was developed for generating a three-dimensional measuring scene of circular test plots of constant radius to solve problems in the forestry sector using a mobile laser scanner

Published: November 2024

The purpose of the study is to automate the process of creating forest cultures. The object of the research is the design and technical solution of an autonomous reforestation robot for planting seedlings of coniferous forest crops (pine, spruce). Land degradation and desertification is a significant problem for ensuring food security in the Russian Federation. More than 100 million hectares of agricultural land are at risk of loss of fertility due to large-scale degradation and desertification. The lack of qualified personnel and low-productivity manual labor do not allow for the most efefctive use of the tight deadlines for reforestation work. At present, there is an urgent need for advanced developments in the field of technical and economic aspects of forest culture. All known serial models of reforestation machines use the manual labor of the operator to feed seedlings to the working bodies of the device for further planting in the ground in the direction of the machine. In this regard, the productivity of these complexes directly depends on and is limited by the personal skills of the operator. The use of an autonomous unmanned robot, such as the Svyatobor complex being developed, will eliminate the human factor, standardize the quality of planting seedlings, and use the terms of reforestation and forest management work as efficiently as possible. Along with the issue of standardizing the quality of planting seedlings, significant savings in time and resources are achieved by eliminating the need for soil preparation due to the introduction of machine vision, the use of a robot track platform and a special plow that performs opening of the fertile layer directly at the place of planting each seedling. The article describes the concept of the Svyatobor complex, including the main elements and stages of its preparation for work. The results of the development of careful capture of seedlings of coniferous forest-forming species are presented.

Authors: Goswami Dilip Kr.
Published: November 2024

Mantra, indicates chanting of some prescribed verses for designated purposes, is a controversial but interesting and important topic. Scientific validation of mantra is difficult to establish due to the factors like – difficulty in (1) understanding the meaning of the verses, (2) understanding the mode of action, (3) understanding the effect scientifically etc. But traditional experience and classical references strongly support the use and efficacy of Mantra in different references. A number of researches are also already conducted in different levels with the aim to understand it scientifically. In the Ayurvedic classics a number of indications and benefits of Mantra are mentioned in different references like Vishachikitsa (in snakebite mentioned with top priority), Grahachikitsa (conditions that occur due to effect of some unseen, unundentifiable aetiologies etc.). The Ayurvedic scholars have discussed in detail about mantra with special reference to method of learning, practising etc. As a widely discussed noninvasive treatment procedure that is getting topmost priority in a condition like snakebite (a very dangerous and usually fatal poisoning) a discussion on Mantra basing upon the Ayurvedic classics is considered to be informative and thought provoking for the scientific forum.

Authors: Skvortsov V.V. , Skvortsova E.M. , Gorbach A.N.
Published: November 2024

Coronavirus infection, or COVID-19 (COronaVIrus Disease 2019), is a new epidemic infectious disease that poses a danger to the population due to its high contagiousness and the development of complications that are unfavorable for the patient’s life, such as ARDS, respiratory and multiple organ failure. The virus has spread worldwide since its detection in Wuhan, Hubei Province, China on December 12, 2019. The World Health Organization (WHO) has declared it a pandemic. Based on the Decree of the Government of the Russian Federation, the new coronavirus COVID-19 (SARS-COV-2) is included in the list of diseases dangerous to society, along with polio and plague. The world community, united by a common goal – to combat the pandemic, is taking measures to actively immunize the entire population through vaccination. However, despite the availability of many vaccines, the number of cases and deaths remains high. As of December 19, 2021, there were 274 644 270 confirmed cases of coronavirus infection in the world and 5 368 822 deaths. Based on the above data, it becomes obvious that the reasonable use of antiviral therapy drugs is necessary for a favorable outcome of the disease of each patient. The review examines the main antiviral drugs proposed by WHO for the treatment of new coronavirus infection (COVID-19). Studies with statistically significant data are selected, which make it possible to fully judge the effectiveness and make it possible to make an adequate decision on the prescription of these drugs. Based on the data obtained from in vitro studies and clinical trials, the prospect of using the above drugs in the treatment of a new coronavirus infection, their effectiveness in clinical practice, as well as the feasibility of using and possible combinations of prescribing these drugs, which can be used to treat and prevent a new coronavirus infection, are considered. The article discusses the effectiveness of the following drugs: remdesvir, interferon, lopinavir and ritonavir, riamilovir, ribavirin, umifenovir, darunavir and cobicistat, favipiravir, chloroquine and hydroxychloroquine, ivermectin and intravenous immunoglobulins.To achieve the goals and objectives of the TB service, a significant role belongs to the average medical staff, where there is a division of functional responsibilities.

Published: November 2024

Diseases of the cardiovascular system are an urgent problem of modern healthcare. A significant share among these pathologies is arterial hypertension (AH) – a persistent increase in blood pressure (BP) above 140/90 mm Hg. According to some sources, 20–30% of the adult population suffers from hypertension. With age, the prevalence of this disease increases and is more than 50% in people over 60 years of age. A particular problem in cardiology is poor adherence to treatment among patients with hypertension. It is known that about half of these patients do not use medications in accordance with the doctor’s prescriptions, do not follow his recommendations and do not regularly monitor their BP. Studies show that knowledgeable patients with a high level of responsibility pay more attention to their health and respond better to treatment.

Cybersecurity on social media platforms: The use of deep learning methodologies for detecting anomalous user behavior
Authors: Adeoluwa Bennard Babatope  , Vishal Kumar Seshagirirao Anil
Published: November 2024

The exponential growth of social media platforms has brought unprecedented opportunities for global communication, networking, and information exchange. However, this expansion has also given rise to significant challenges, particularly in identifying and mitigating anomalous or malicious user behaviors such as spamming, cyberbullying, and misinformation dissemination. Traditional anomaly detection methods, which often rely on rule-based systems or basic statistical models, have proven inadequate in addressing the complex, dynamic, and evolving nature of user behavior on these platforms. In response, this paper explores the application of deep learning methodologies—specifically Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), Long Short-Term Memory networks (LSTMs), Autoencoders, and Generative Adversarial Networks (GANs)—for detecting anomalous behavior in social media environments. We present a novel deep learning architecture that integrates these models to enhance the detection accuracy of behavioral anomalies. By leveraging large-scale datasets and advanced feature extraction techniques, our approach demonstrates significant improvements over traditional methods, with higher precision, recall, and overall detection rates. The proposed model's ability to adapt to new and emerging patterns of behavior underscores its potential for real-world application in monitoring social media platforms. This research contributes to the growing body of literature on deep learning for cybersecurity and digital trust, offering a robust solution for maintaining the integrity of online social spaces. Our findings suggest that the implementation of these advanced methodologies can provide a more secure and reliable social media environment, benefiting both users and platform providers alike.

The inhibitory effect of both salts (NaCl and KCl) was analyzed on modified nutrient agar and nutrient broth (Media + 5% salt conc., Media + 10% salt conc., Media + 15% salt conc., Media + 20% salt conc.). The study measured culture growth using optical density readings at 425nm over 48 hours with different NaCl and KCl concentrations, while growth on plates was visually assessed on colony counter. Results: The highest optical density recorded as a result of contact with varying concentration of sodium chloride was 0.48 at 5% concentration after 48hours incubation while the least was 0.04 at 20% concentration after 12hours incubation while the highest optical density recorded as a result of contact with varying concentration of potassium chloride was 0.41 at 5% concentration after 48hours incubation while the least was 0.01 at 20% concentration after 12hours incubation. Conclusion: Higher salt concentrations resulted in osmotic shock, suppressing growth in Staphylococcus aureus, but increased salt concentration partially alleviated growth inhibition over time

Relasi Kuasa Dalam Fenomena Bullying di Sekolah

Maraknya bullying atau perundungan di sekolah merupakan sebuah ironi yang memprihatinkan. Sekolah sepertinya masih belum terbebas dari praktek-praktek kekerasan yang melibatkan relasi kuasa antara pihak yang dominan dengan pihak yang dianggap sebagai sub ordinat. Masih terdapat budaya patriarkhi yang memandang pihak perempuan sebagai kelompok lemah di satu pihak di hadapan laki-laki sebagai yang memiliki keunggulan di pihak lain. Demikian juga masih terdapat budaya feudal yang memandang kelompok yang memiliki status sosial tertentu dianggap lebih hebat dan berhak atas privilege dan prestige atas kelompok lain. Sekolah sebagai Lembaga Pendidikan diharapkan berfungsi emansipatoris, membebaskan dari berbagai praktek relasi sosial yang tidak adil, termasuk bullying tersebut, sehingga sekolah menjadi tempat yang nyaman, aman dan bermakna bagi kehidupan dan tumbuh kembang anak-anak generasi bangsa. Tulisan ini akan melihat akar masalah sosial dari praktek-praktek perundungan di sekolah dihadapkan dengan konsep Pendidikan/kurikulum yang “menekan”. Metode tulisan ini dilakukan dengan penelusuran berbagai literatur, seminar tentang bullying dan melakukan wawancara mendalam (indepth interview) bersama guru-guru dan siswa-siswi SMPN 3 Kramatwatu, tempat KKM Unsera kelompok 35 tahun 2024 melaksanakan tugasnya. Temuan cukup menarik bahwa praktek bullying merupakan gambaran praktek dari struktur sosial di masyarakat yang tidak adil, seperti patriakhi dan feudalism sebagai gambaran praktek relasi-kuasa yang amat kental dan belum sepenuhnya terbebas dari Lembaga Pendidikan kita. Beberapa rekomendasi muncul agar dapat mengurangi atau mengantisipasi perilaku bullying, yakni memperkuat Lembaga BK (Bimbingan Konseling) di sekolah dan menghadirkan kurikulum yang membebaskan dari belenggu ideologis yang tidak adil selama ini.

Al-Quran merupakan pedoman hidup bagi umat Islam. Kewajiban bagi umat Islam untuk membacanya dan memahami maknanya. Namun, tidak semua orang memiliki akses dengan mudah untuk memiliki Al-Quran. Waqaf Quran adalah perbuatan sosial yang mulia dengan mewaqafkan mushaf Quran untuk dihibahkan kepada umat Islam, agar dapat dibaca, dipelajari, dan diamalkan isinya. Tujuan pengabdian masyarakat ini untuk meningkatkan kecintaan terhadap Al-Quran agar lebih semangat membaca AlQur’an, dan rajin menghafal Al-Quran, terutama  bagi anak anak yatim piatu melalui program waqaf Quran di Desa Pabuaran, Cilegon. Program ini mendonasikan mushaf Syaamil Al-Quran kepada keluarga kurang mampu dan anak yatim piatu. Kegiatan acara dimulai dengan pelaksanaan kegiatan pengajian rutin di isi dengan sosialisasi gaya hidup Halal (halal lifestyle), selanjutnya diserahkan donasi Quran kepada penerima waqaf Qur’an. Pengajian diadakan di masjid setempat dengan partisipasi lebih dari 50 orang. Dukungan yang kuat dari tokoh masyarakat dan ketua majelis turut berkontribusi signifikan terhadap keberhasilan program ini. Meskipun terdapat tantangan seperti keterbatasan sumber daya dan konsistensi partisipasi, program ini berhasil mencapai tujuannya dalam meningkatkan aksesibilitas serta meningkatkan kecintaan terhadap Al-Quran di komunitas Desa Pabuaran. Secara keseluruhan, hasil dari penelitian ini memberikan pandangan yang berharga bagi pengembangan program serupa di wilayah-wilayah lain, dengan adaptasi yang sesuai dengan karakteristik dan kebutuhan setempat.
