Математическое моделирование одного эффективного способа селективного забора воды из промежуточного слоя трехслойного стратифицированного водоема
Authors: И.Д. Музаев , К.С. Харебов , Н.И. Музаев
Published: October 2024

Разработан новый эффективный способ селективного забора воды из промежу точного слоя трехслойного стратифицированного водоема. Математическим и ком пьютерным моделированием впервые в мире доказано утверждение о том, что ес ли из всех трех слоев водоема синхронно забирать воду, то поверхности раздела слоев не искривляются и в отличие от существующих способов не создаются кри тические ситуации забора воды. Доказательством эффективности разработанного способа стала возможность забирать воду из промежуточного слоя с высоким рас ходом. В промежуточном слое вода бывает холоднее и чище, чем в других слоях водоема.

The purpose of the article is to develop an effective water intake method for selective water intake from the intermediate layer of a three-layer reservoir with density stratification, where the water is colder by 8–10 ∘C compared to the temperature of the surface layer and at the same time cleaner than in the bottom layer of the reservoir. Methodology of hydrodynamics of vortex free motion of an ideal incompressible fluid is used. A spatial three-layer contact initial boundary value problem has been set and solved analytically, which mechanically and mathematically models the above-described new method of selective water intake from the intermediate layer. A set of calculation formulas for the laws of oscillation and curvature of the interface of layers is obtained. The novelty of the method relies on the fact that water from all three layers is synchronously taken through three windows arranged on the side of the reservoir so that they fit in one vertical strip symmetrically relative to the initially stationary horizontal planes of the water layers section. Computer experiments have proved that with synchronous water intake from all three windows, the interface surfaces of the layers practically retain their original horizontal positions. In this regard, it becomes possible to selectively take water from the intermediate layer through an intermediate window with a relatively high flow rate. This is the effectiveness of the proposed method of water intake from a stratified reservoir.

Предложены три приема сокращения времени, необходимого для расчета одно го значения или ряда значений дифракционной эффективности, полученных с по мощью алгоритмов строгого анализа связанных волн. Это прием, использующий свойства матрицы Теплица, прием уменьшения количества переменных в функ ции коэффициентов Фурье и прием использования параллельных вычислений. На примерах задач по построению зависимостей дифракционной эффективности двухслойных двухрельефных пилообразных микроструктур с просветляющими по крытиями от угла падения излучения и температуры показано, что использование свойств матриц Теплица позволяет существенно сократить время расчета. Парал лельные вычисления также сокращают время вычислений, но при этом использу ется больше оперативной памяти.

Rigorous coupled-wave analysis is a widely used method to determine the diffraction efficiency of periodic structures. The computational complexity that arises when implementing algorithms for rigorous coupled-wave analysis is characterized by the time required for the calculation and the amount of RAM used by the computer. The calculated time, in turn, depends on the selected parameters of the number of plane waves (modes), the sum of which determines the electromagnetic field, and the number of lattice plates into which the periodic structure is divided. This paper proposes three techniques for reducing the time required to calculate a single value or series of diffraction efficiency values obtained using rigorous algorithms for coupled wave analysis. The first technique uses the properties of Toeplitz matrices, which are the matrices of Fourier coefficients when expanding the dielectric constant of each lattice plate into a series. The second technique reduces computational complexity by reducing the number of variables in the Fourier coefficient function. The third technique uses parallel computing to calculate a set of Fourier coefficient matrices and a set of diffraction efficiency values. Using examples of problems of constructing the dependences of the diffraction efficiency of two-layer double-relief sawtooth microstructures with antireflection coatings on the angle of incidence of radiation and temperature, it is shown that the use of the properties of Toeplitz matrices can significantly reduce the calculation time. The second technique insignificantly reduces the calculation time. Parallel computing significantly reduces computation time, while using more RAM. By combining the proposed techniques, a working algorithm that meets the user’s requirements for the estimated time and available RAM of the computer is proposed.

The research is aimed to describe the numerical method for studying population models based on the reaction–diffusion–advection equations with variable coefficients. It is important to analyze the impact of directed migration towards a resource on temporal-spatial competition of species. We apply a method of lines with a staggered grid for discretizing the nonlinear problems with high order accuracy on three-point stencil in spatial coordinate. To integrate in time, a high order Runge–Kutta method is used (ode89 in MATLAB). The scheme was tested using special problems allowing exact solutions. We carried out calculations of stationary distributions for species in a heterogeneous environment under various boundary conditions. Numerical estimates of accuracy orders were obtained using the given scheme and compared with the second order approximation analogue. We performed a computational experiment to assess the order of approximation with non stationary regimes using the Aitken process. Our results demonstrate the effectiveness of a compact scheme for calculating the dynamics of three species competing in a heterogeneous habitat.

Published: October 2024

Работа представляет собой продолжение цикла исследований авторов, посвященных компактным схемам для численного решения задач нелинейной волоконной оптики. В качестве средства вычислений на неравномерных сетках предложена двухслойная схема типа предиктор-корректор, построенная по аналогии с хорошо зарекомендовавшей себя безытерационной схемой, ранее предложенной авторами для частного случая равномерной сетки. Изменен способ генерации адаптивной сетки — вместо конструирования управляющей функции по решению разработан явный способ задания сетки со сгущением в зонах больших градиентов, опирающийся на базовое преобразование Бахвалова. Приведены результаты численных экспериментов, выполненных на модельных задачах с известными точными решениями.

The paper is a further development of the authors’ research cycle on high-precision difference methods for numerical solution of nonlinear fiber optics problems (for the Schr¨odinger equation and the Ginzburg–Landau equation). A two-layer predictor-corrector type scheme is chosen as the О применении специальных адаптивных сеток ... 53 apparatus for computations on non-uniform meshes, which is constructed by analogy with the well proven noniterative scheme previously proposed by the authors for the special case of a uniform grid. In contrast to the frequently used three-layer scheme, which requires setting initial conditions on the first two layers on the evolutionary variable, the two-layer technique has no problems when a computation is started. Instead of the frequently used method of adaptive mesh generation relying on the construction of a control function based on a dynamically varying solution, an explicit method of setting the denser mesh in the zones of large gradients, based on the classical basic Bakhvalov transformation and on the knowledge of soliton locations, is applied. The global coordinate transformation is constructed by smooth conjugation of elementary basic transformations. It allows saving computational resources and avoiding undesirable larger grid step near extrema of the second derivative of the solution, for example, near the soliton peak or base. On two test problems the comparison of schemes of the fourth and second order of accuracy on constructed special grids and on uniform grids with the same number of steps is carried out. The order of accuracy of the schemes at moderate gradients of the solution is numerically confirmed. It is shown that at large gradients a reasonably constructed adaptive grid is a more important factor of computational efficiency than the order of accuracy of the schemes.

The Dissociation and Reduction of Molecular Oxygen on Platinum, Palladium, Iridium, Rhodium, and Gold
Authors: Brandes Benedikt Axel
Published: October 2024

Herein, a method is presented to determine the kinetics of the oxygen dissociation on different metals, allowing for the determination of the oxygen reduction reaction mechanism. This analysis reveals that molecular oxygen rapidly dissociates to underpotentially deposited oxygen species on platinum and rhodium surfaces. These species' experimentally determined surface charges lead to a simple kinetic model of the ORR, which agrees well with experimental ORR activities and predicts the Volcano relationship with the oxygen reduction reaction.
Assigning surface hole polaron configurations of titanium oxide materials to excited state optical absorptions
Authors: Boyd Cassius , McBride Shay , Paolino Michael , Lang Moritz , Hautier Geoffroy , Cuk Tanja
Published: October 2024

For water splitting, a comprehensive understanding of the underlying reaction intermediates and pathways is crucial for optimizing existing materials or discovering novel ones. Among the most well-known active photoanodes for the oxygen evolution half-reaction are various TiO2-based materials. A hole polaron, which consists of a metal-oxide distortion around trapped holes, has been suggested as a local reactive oxygen configuration for the oxidative reaction. While first principal calculations identify new electronic states in the middle of the band gap due to hole-polarons and the influence of hole-polaron dynamics on transport, an assignment of hole-polaron configurations to a measured spectrum has been challenging due to broad optical transitions in the visible regime. Here, we compare the excited state absorption (ESA) for two titanium oxide materials with a similar electronic structure, but different titanium-oxide crystal structure and find that the maximum in the broad spec-trum shifts from 3.1 eV in rutile TiO2 (100) to 2.2 eV in perovskite SrTiO3. A principal component analysis isolates the ESA generated at ultra-fast timescales (< 1 ps) in the pump-probe spectroscopy. Density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations predict the energies of the mid-gap states for stable hole-polarons and the corresponding spectra from the valence band, respectively. When compared to the experimental spectra, we can rationalize the shift in the ESA by the transition optical dipole, considering both the edge and deeper states in the valence band, being bright for certain configurations of hole polarons in rutile TiO2 (100) (terminal O•-) and STO (lateral Ti2O•-). The spectral assignment of the ESA in two transition metal oxides materials via their distinctive crystal structures paves the way for the assignment of hole-polaron configurations and their dynamics in other transition metal oxides for oxygen evolution catalysis and more-generally, photo-driven processes.

Published: October 2024

Silicon's versatility as a semiconductor renders it indispensable across various domains, including electronics, sensors, and photovoltaics. Modifying hydrogen-terminated silicon surfaces with moieties adsorption offers a method to tailor the material’s properties for specific applications. In this study, we employ ab initio density functional theory calculations to explore the energetics of single alkyl, 1-alkenyl and 1-alkynyl moieties adsorbed on H-terminated Silicon (111) surface. We analyse the interfacial dipole induced by Si–C bond formation that determines the Schottky barrier and examine the alignment of the frontier orbitals energy levels with silicon band structure related to the charge transfer tunnelling mechanism. Our findings provide valuable insights into how aliphatic moiety functionalization affects interfacial electronic properties, offering clues for optimizing silicon-based devices.
Solid electrolyte interphase (SEI) triggered electrochemical hydrogenation of nitrobenzene with an undivided cell
Authors: Pan Shenghao , Liu Jianguo
Published: October 2024

The hydrogenation of nitrobenzene is a vital route to obtain industrially valuable aniline. Strategies have been developed to accomplish this transformation sustainably and efficiently corresponding to the green requirement of modern chemistry. The study explores an electrochemical protocol to obtain the expected product in an undivided cell without loading heterogeneous catalysts on electrodes. An additive, tripyrolidinophosphine (TPPA), forming a solid electrolyte interphase (SEI), inspired by a lithium battery technology, triggers this reaction that would otherwise not occur in a LiBr/THF system. δ-valerolactam (2-piperidone), a unique hydrogen donor, provides the H species and elevates the aniline selectivity to 75.48%. Two reductive paths are discovered existing in this system where aniline is produced from both the direct hydrogenation of phenylhydroxylamine and the indirect hydrolysis of azobenzene. Gram scale reactions are performed under batch and flow conditions, respectively, to make this protocol applicable in practice.
Alkane Dehydrogenation and H/D Exchange by a Cationic Pincer-Ir(III) Hydride: A Novel Mechanism of C-H Addition and 𝛽-H Elimination Leads to Unprecedented Selectivity
Authors: Parihar Ashish , Emge Thomas J. , Hasanayn Faraj , Goldman Alan S.
Published: October 2024

We report that the cationic iridium complex (iPrPCP)IrH+ undergoes addition of alkane C-H bonds, which is manifested by catalytic alkane transfer-dehydrogenation to give alkenes and by hydrogen isotope (H/D) exchange (HIE). Contrary to established selectivity trends found for C-H activation by transition metal complexes, strained cycloalkanes, including cyclopentane, cycloheptane, and cyclooctane, undergo C-H addition much more readily than n-alkanes which in turn are much more reactive than cyclohexane. Aromatic C-H bonds also undergo H/D exchange much less rapidly than those of the strained cycloalkanes, but much more favorably than cyclohexane. The order of reactivity toward dehydrogenation correlates qualitatively with the reaction thermodynamics, but the magnitude is much greater than can be explained by thermodynamics. Accordingly, the cycloalkenes corresponding to the strained cycloalkanes undergo hydrogenation much more readily than cyclohexene, despite the less favorable thermodynamics of such hydrogenations. Computational (DFT) studies allow rationalization of the origin of reactivity and the unusual selectivity. Specifically, the initial C-H addition is strongly assisted by 𝛽-agostic interactions, which are particularly favorable for the strained cycloalkanes. Subsequent to 𝛼-C-H addition, the H atom of the 𝛽-agostic C-H bond is transferred to the hydride ligand of (iPrPCP)IrH+, to give a dihydrogen ligand. The overall processes, C-H addition and 𝛽-H-transfer to hydride, generally show intermediates on the IRC surface but they are extremely shallow, such that the 1,2-dehydrogenations are presumed to be effectively concerted although asynchronous.
New fluorogenic triacylglycerols as sensors for dynamic measurement of lipid oxidation
Authors: Handke Maria , Beierlein Frank , Imhof Petra , Schiedel Matthias , Hammann Simon
Published: October 2024

Lipids are major constituents of food but are also highly relevant substructures of drugs and are increasingly applied for the development of lipid-based drug delivery systems. Lipids are prone to oxidative degradation, thus affecting the quality of food or medicines. Therefore, analytical methods or tools that enable to assess the degree of lipid oxidation are of utmost importance to guarantee food and drug safety. Herein, we report the design, synthesis, and application of the first-in-class fluorogenic triacylglycerols that enable a dynamic monitoring of lipid oxidation via straightforward fluorescence readout. Our fluorogenic triacylglycerols can be used both in an aqueous and lipid-based environment. Further, we showed that the sensitivity of our fluorescent tracers towards oxidation can be tuned by incorporating either saturated or unsaturated acyl chains in their triacylglycerol core structure. With this, we provide a first proof-of-principle for the applicability of fluorescently labelled triacylglycerols as tracers to monitor the dynamics of lipid oxidation, thus paving the way for novel discoveries in the area of lipid analytics.
The Restoring Force Triangle: A Mnemonic Device for Polymer Mechanochemistry
Authors: Sun Yunyan , Xie Fangbai , Moore Jeff
Published: October 2024

In polymer mechanochemistry, mechanophores are specific molecular units within the macromolecular backbone that are particularly sensitive to tension. To facilitate understanding of this selective responsiveness, we introduce the Restoring Force Triangle (RFT). The RFT is a mnemonic device intended to provide intuitive insight into how external tensile forces (i.e., stretching) can selectively activate scissile bonds, thereby initiating mechanically driven chemical reactions. The RFT utilizes two easily computable parameters: the effective bond stiffness constant, which measures a bond’s resistance to elongation, and the bond dissociation energy, which is the energy required to break a bond. These parameters help categorize reactivity into thermal and mechanical domains, providing a useful framework for developing new mechanophores that are responsive to force but thermally stable. The RFT helps chemists intuitively understand how tensile force contributes to the activation of a putative mechanophore, facilitating the development of mechanochemical reactions and mechano-responsive materials.

Published: October 2024

The present cross-sectional, quantitative study investigates the classification capabilities of ML and DL in processing data from IoT-enabled medical devices: heart rate variability (HRV), blood pressure, blood glucose levels, and physical activity in patients with diabetes and cardiovascular diseases. Eight patients from AIIMS, New Delhi participated in this study. In the current investigation, two types of measurements are taken into consideration: cardiovascular measures and diabetes management metrics, which include BMI, blood pressure, blood glucose, physical activity, and HRV. The outcomes showed a positive association with blood glucose level and age (0.55), negative correlation between blood glucose and physical activity (-0.68), which had significant significance towards exercising importance in diabetes management. Blood glucose correlated moderately favorably with BMI with 0.45, while age and BMI correlated at 0.32. These results show how ML and DL techniques can improve the interpretation of complex health parameters from IoT-enabled devices to better manage patients and develop specific healthcare plans in chronic diseases.

Published: October 2024

This research aims at examining how the regulator can make regulation to optimize financing implementation with YouTube content as a collateral. This research is considered necessary, because besides Government Regulation Number 24 Year 2022 which becomes the basis to give financing under an intellectual property as a collateral, banking institutions might still be in doubt to implement such a financing scheme due to many weak supporting regulations. This research is conducted with a normative-juridical approach method. The research shows that there are still many regulations which have not accommodated the financing implementation of intellectual property-based financing scheme basis, especially those regulations related to valuation, recognition of intellectual property as a banking asset and execution of intellectual property when a debtor default. The weak regulation of these three aspects makes financial institutions doubtful to implement the intellectual property-based financing especially because bank activities are to collect and distribute funds to the society. The conclusions of this research show that basically there has been a method or way to anticipate the three problems, but it needs to be legalized in a form of regulation so that the bank has legal certainty and protection in its financing with intellectual property as the collateral. The regulators are supposed to be able to create regulation to optimize financing implementation with intellectual property as the collateral.

Doubt Method Between (Al-Ghazali and Descartes)
Authors: Abubakr Hamad Kaify , Ismael Jamal Jutyar , Qadir Sabir Aram
Published: October 2024

This research, The Method of Doubt between (Al-Ghazali and Descartes), interprets and explains the similarities and differences of the two philosophers on the issue of knowledge from doubt to certainty. In order to understand the truth and different dimensions of this issue, which belongs to two different worldviews and eras in the medieval Islamic and modern European world, the theses and arguments of both philosophers on doubt as the beginning and path to knowledge and certainty are discussed. This is done by highlighting their main views on their chain of reasoning, how arguments begin with the precedence of doubt until they reach the truth. Although most of their arguments are similar, but they differ in the way they get rid of doubt and reach certainty. This radical difference is that Descartes reaches certainty and truth through doubt, within rational thinking, and his Cogito (I think, Therefore I am), but Al-Ghazali in his Sufi Philosophical journey (Mysticism), he waits for the truth to be revealed to him by God (Allah) and put into his heart as a bright and illuminating light, which is a kind of enlightenment of the heart.
However, despite the methodological differences between both of them in the Rational and the heart knowledge, doubt and the method of doubt for both are steps towards achieving certain knowledge beyond all doubt, to access emphatic knowledge, but each gives different status to consciousness and emotion, as well as to mind and heart. As a result, we find that the experiences of both philosophers in sustaining preconceptions and methods of arriving at truth are important and unique, even though they belong to two different philosophical and religious worldviews.

Gender identity refers to the way humans view themselves and perceive themselves to be attractive both sexually and romantically. It is an individual's appreciation and satisfaction of being heterosexual, bisexual, homosexual, or cisgender. It refers to an individual's sexual understanding of himself and is part of one's identity, which is different from the sexual understanding of oneself. Gender identity disorder means a robust desire of pertinence towards the opposite sex and robustly insistence on this otherness.
 Avoidance is classified within the framework of cluster 3 of personality disorders, which is identified by The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Hence, one can argue those who have this kind of personality disorder may appear in them withdrawal behavior; and they view themselves as restless, and they feel that they are rejected and despised by others.
 The researcher argues that homosexuals in Kurdish society are not accepted, and a large majority of people see them as sick, and others as victim due to their vulnerability to social and psychological problems. This study aims at finding relations between gender identity disorder and symptoms of avoidance in homosexual persons. The descriptive and relational methodology is used to intentionally select 108 subjects, 84 males and 24 females.
Based on literatures and contemporary studies in the field, the researcher prepares the items of the gender identity disorder, yet for symptoms of avoidance, the researcher relies on and takes its terminologies from The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The terminologies in both variables are presented to groups of experts in education, psychology, and psychiatrics, and for extracting stability from both the measures, (split-half) and (alpha Cronbach’s) is used. After applying the last measures on individuals from the sample of the study, statistics of the data is analyzed using Statistical Package for the Social Sciences (SPSS). The study concludes that there is a robust, positive and significant correlation between gender identity disorder and avoidance symptoms among homosexuals. Based on the results recommendations are also given.

Islam's view of women and their rights is a multifaceted view. Islam’s view of women includes all their aspects and roles, therefore respecting their rights in society as human beings also as a mother, a sister and as a daughter.
For each of these women’s status (human being, mother, sister, girl), Islam assigned the rights and fair duties to them and saved them from the oppression of ignorance that has been done to them. Islam also has raised their status and given them the right to participate in building society and improving their levels and abilities. The ruling on women working outside the home is one of the issues that is debated in Islamic centres, Jurisprudence and religious centres have conducted detailed research in this area. If we look at human society today, we see that many women have proved their skills in their work and expertise. They have an active partnership in the development of societies in all areas, even some of those areas that cannot be done without women and without women's participation are close to disability and immobility.
At the same time, the work of women in societies has created some problems for society, and women themselves have increased their obligations because of their work and has caused some social problems, including increased crisis and delay in marriage as well as some crimes and other problems.
This research aims to discuss the ruling on women working outside the home and determine the conditions and guidelines of this issue and the appropriate places that exist for women to work and the impact of women's work in the economic development of countries and societies. It raises all these from the perspective of Islamic jurisprudence.

Authors: Kılıç Şafak Nazire , Erdem Hüseyin
Published: October 2024

Background/Aim: Anatomy plays a crucial role in medical and dental education, equipping students with vital knowledge for comprehending the human body and its clinical implications. The COVID-19 pandemic led to a significant transition to online learning, raising questions about the efficacy of virtual anatomy education. Additionally, recent natural disasters like earthquakes have disrupted traditional learning settings, highlighting the need for alternative methods such as online instruction. This study sought to investigate dentistry students' opinions on anatomy education, specifically comparing the perspectives of students affected by earthquakes with those who were not, to determine any disparities in their attitudes towards online anatomy courses.
Methods: A voluntary survey was conducted on 135 first-year students at Çukurova University Faculty of Dentistry during the 2023-2024 academic year. A 5-point Likert-type survey with 21 questions was used for data collection. Results were presented as percentages and analyzed. The Likert scale ranged from 1 = Strongly Disagree to 5 = Strongly Agree. Statistical analysis was performed using SPSS 20.0, including Kolmogorov-Smirnov and Shapiro-Wilk Tests for normal distribution assessment and the Mann-Whitney U-test for non-normally distributed scores comparison (P-value <0.05).
Results: Students directly affected by earthquakes showed a significant difference in their perception of online education compared to unaffected students, particularly in the question "Theoretical anatomy course can be followed online" (P=0.036).
Conclusion: This study provides insights for enhancing education planning and development based on student feedback.
