A Comparative Study on MHD Forced Convective Flow of Different Nanofluids with Water (H2O) as Base Fluid in a Vertical Rectangular Duct
Authors: Das Bishnu Ram , Deka P.N. 
Published: April 2024

In this paper, a comparative study on MHD forced convective flow for heat transfer efficiency of different nanofluids with water (H2O) as base fluid has been carried out. Here, in this study flow through vertical rectangular has been considered in presence of strong magnetic field. In this laminar flow we consider duct walls as electrically non-conducting where the transverse magnetic field acting normally on the duct walls. Joule heat and the viscous dissipation effects are included in the energy equation and furthermore the walls of the duct are kept at constant temperature. An explicit finite difference method has been adopted with fine grid in the control volume for solving the governing equations of this MHD nanofluid flow. Computational processes are carried out using MATLAB code. In this present work we have plotted the flow fields velocity, induced magnetic field, and temperature for various values of MHD flow parameters graphically by varing thermal Grashof number (Gr), Hartmann number (Ha), Reynold number (Re), Eckert number (Ec), Prandtl number (Pr), magnetic Reynold number (Rm), and nanoparticle volume fraction (ϕ) respectively.

Published: April 2024

Sol gel auto-combustion was used to create gadolinium doped nickel ferrite nano-particles, which have chemical composition NiFe2‑xGdxO4 (x = 0.00, 0.010, 0.15, 0.20 & 0.25). The investigation focused on how the composition of Gd+3 affected the magnetic properties and structural parameters. Magnetic properties were investigated using VSM technique, structural properties were determined using XRD and SEM techniques. XRD graphs verified the establishment of the spinel ferrite phase. With an increase in Gd composition, the crystallite size and lattice parameter increased from 21.0288 to 27.04125 nm and 8.3325 to 8.3367Å, respectively. It was also evident how the composition of Gd+3 affected the estimation of bond-angles and lengths in tetrahedral and octahedral structures. SEM micrographs showed that all of the grains had a small amount of agglomeration and that all of the synthesized compositions were homogenous. The range of 140.5–176.2 nm was found to be the average grain size. Using VSM at 300K, magnetic parameters like coercivity, residual magnetization, and saturation magnetization were computed. Until the composition was 0.20, the saturation magnetization and residual magnetization dropped from 30.28 emu/g to 15.35 emu/g and 5.07 emu/g to 3.65 emu/g, respectively. After that, they increased to 34.40 emu/g and 6.52 emu/g, respectively. Until composition 0.20, coercivity was raised from 154 to 261 Oe; after that, it was lowered to 233 Oe.

It is shown that the dynamics of changes in the state of nickel clusters depends on the temperature of the diffusion maximum and the cooling rate. It was found that with increasing annealing temperature and cooling rate, an increase in density and a decrease in cluster size are observed. In this case, the main attention was paid to the determination of the laws governing the change in the density, size, and structure of clusters from temperature and cooling. The process and dynamics of the interaction of clusters depends on the diffusion coefficient of impurity atoms in the lattice and the level of supersaturation of the solid solution. It has been established that with a change in the annealing temperature from T = 1100℃ to 1250℃, the cluster density increases by almost 1-1.5 orders of magnitude, and their size decreases by a factor of 5–6. It seems to us that to obtain clusters with stable parameters, the optimal cooling rate is 200–300℃.

Published: April 2024

This research focuses on the synthesis of carbon nanotube (CNT) and Poly(3-hexylthiophene) (P3HT) (pristine polymer) with Ag doped (CNT/ P3HT@Ag) nanocomposite thin films to be utilised in various practical applications. First, four samples of CNT solution and different ratios of the polymer (P3HT) [0.1, 0.3, 0.5, and 0.7 wt.%] are prepared to form thin layer of P3HT@CNT nanocomposites by dip-coating method of Ag. To investigate the absorption and conductivity properties for use in various practical applications, structure, morphology, optical, and photoluminescence properties of CNT/P3HT @Ag nanocomposite are systematically evaluated in this study. In this regard, the UV/Vis/NIR spectrophotometer in the wavelength range of 350 to 700 nm is used to investigate the absorption, transmission spectrum, extinction coefficient (k) and refractive index of the samples prepared at room temperature. The XRD results indicate a slight increase in the crystallite size of the synthesized (CNT/ P3HT@Ag) nanocomposite compared to CNT/P3HT nanocomposite, which can be attributed to the better dispersion of the P3HT and its favorable wrapping around the carbon nanotube structures. FESEM results show that the Ag nanoparticles are acting as a bridge between the CNT and P3HT, creating a strong bond between the two materials that is strong enough to form thicker tubular structures. An appreciable increase in absorbance intensity (approximately 552 nm) is obtained by adding silver nanoparticles to the CNT/P3HT matrix at 0.5% of P3HT. Additionally, the prepared CNT/P3HT@Ag thin films show greater transmittance – more than 42%, 45%, 49%, and 48% for P3HT concentrations of 1%, 3%, 5%, and 7%, respectively. The preparation of the samples' extinction coefficient (k) and refractive index data show that the inclusion of silver nanoparticles to the CNT/P3HT nanocomposite matrix has a significant improvement over the previous samples (CNT/P3HT composite).

In this paper the content of heavy metals at the territory of Pyatihatki settlement, where the National Scientific Center Kharkiv Institute of Physics & Technology (NSC KIPT) is located. The nuclear-physical methods were used to determine the content of chemical elements in the soil samples taken in 30 points at the territory of Pyatihatki settlement in 2011-2021. The elemental analysis was carried out on the analytical nuclear-physical complex "Sokol". The methods, based on registration of characteristic X-ray radiation of atoms and g-radiation of nuclei excited by accelerated protons, were used. After the measurements completion, the data arrays on the content of 15 chemical elements (N, Na, S, Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Zr, Br, Sr, Pb) in the soil samples were obtained. The data arrays processing was carried out using the EPA (Environmental Protection Agency) PMF v3.0.2.2.2 software based on the application of the PMF (Positive matrix factorisation) algorithm. ArcView 3.2a was chosen as the basic software product for the analysis of spatial distribution of the major polluting chemical elements. As a result of the performed work, the pollution sources, which have an impact on the territory near the NSC KIPT, have been identified. The source of the soil pollution is the autostrades, among which the road around the city Kharkiv stands out, where an increase in the content of Pb, Sr, Zr, Cr and Cu was detected. A source of chromium contamination, located presumably to the north-east of Pyatihatki settlement, was identified. The analyses of the obtained data showed that the PMF method allows to identify the factors that affect the soil contamination, and to determine the presumptive sources of pollution with the help of wind rose.

Published: April 2024

: Computer technology with digital power will bring better tax payment procedures and expectations of compliance levels. The digital world will encourage increasingly widespread use of artificial intelligence components to make tax-related work easier. This research falls under comparative causal studies using a survey method. The population consists of MSME operators (individual taxpayers) in the city of Binjai who have filled out and returned the questionnaire to the researchers. The sample selection was carried out using purposive sampling technique, and data was gathered from the opinions or perceptions of MSME operators (individual taxpayers) in Binjai. The primary data obtained were descriptively analyzed, and the model and the influence of tax rates and tax penalties on taxpayer compliance through tax understanding were examined using path analysis. The findings indicate a significant influence of tax rates and tax penalties on taxpayer compliance both simultaneously and partially, with tax understanding as an intervening variable not fully proving to mediate the relationship between tax rates and penalties on taxpayer compliance. The low path analysis value in this study should be considered by subsequent researchers to include other variables that may affect corporate value

Published: April 2024

Mapanget District is one of the administrative parts of Manado City which has service functions, namely housing and new settlements, tourism, and trade and services. The Mapanget District is part of the new city planning in the 2015–2019 RPJMN to account for unequal development in the city core. Predicting the development of residential land use is crucial to avoid uncontrollably detrimental effects on suburban communities. To forecast land development over 20 years, from 2022 to 2042, this study will employ spatial analysis based on the Geography Information System-Cellular Automata and weighting analysis using the Analytic Hierarchy Process (AHP) technique to analyze potential deviations in the spatial pattern development of Manado City settlements, particularly Mapanget District. The software used for this research's simulation procedure is LanduseSim 2.3.1, QGIS, and Archmap 10.8. According to the projection results, residential land use will vary during the following 20 years, starting in 1956.75 Ha, or a 201% increase, resulting from the most important driving factor, which is closeness to existing towns. 1106.79 Ha is the possible deviation depending on the direction of the spatial pattern plan for residential structures. It is advised to plan tall buildings, particularly for settlements, as the current residential land in Mapanget District exceeds both the carrying capacity and the land capacity as of 2042, according to the prediction results.
Challenges to Building a Viable Alternative to Ethnonationalism in the Armenia-Azerbaijan Conflict Setting
Authors: Gamaghelyan Philip , Huseynova Sevil 
Published: April 2024

Abstract
The article looks into why, to date, discourses of peace in the Armenia-Azerbaijan conflict context failed to present a challenge to the hegemony of ethnonationalism. With the liberal world order in crisis and Armenian and Azerbaijani identities entering a period of redefinition following the latter’s overwhelming military victory and exodus of the Armenian population from Nagorno-Karabakh, the article argues for a sustained effort towards rethinking peace and ongoing dialogue among realist, liberal, and post-liberal thinkers a road towards a multifaceted and interdisciplinary process that could move the South Caucasus away from violence and towards peace.
Learnability Theory and Rural Roma Children’s Knowledge of Languages: An Empirical Psycholinguistic Comparative Study
Authors: Kyuchukov Hristo 
Published: April 2024

Purpose The purpose of the study is to examine Learnability Theory (Valiant, 1984) in the process of learning of L2 Bulgarian and Czech languages by preschool Roma children. Roma children grow up in a rich oral culture and learn their mother tongue from the members of extended families, but how they learn the L2 and which factors facilitate the process second language acquisition (SLA) is not clear.
Methods. 20 bilingual Roma children from Bulgaria and 20 bilingual Roma children from the Czech Republic (in two age groups 4–5 and 5–6-years-old) were tested with linguistic tests on their knowledge, centering on their ability to learn new grammatical categories. The children were tested with a specially developed test, bearing in mind the peculiarities of Romani grammatical categories. The same grammatical categories were tested in the official languages of the countries where the children live – in the Bulgarian and Czech languages.
Results. The findings show that the children from Bulgaria are much better in learning Bulgarian than the Roma children from Czech Republic learning Czech. There is a connection between the knowledge of the Roma children of their mother tongue and the official language. The data shows that the Bulgarian Roma children know their mother tongue much better and this helps them to better learn Bulgarian, while the Czech Roma children have a comparatively poor knowledge of Romani and they acquire the Czech ethnolect – the variety of Czech spoken by Roma, which differs from official standard Czech.
Conclusions. The study showed that learning grammatical categories form a new language in early age dependence form the language knowledge and experiences of the child in their mother tongue. The new knowledge in a new language is acquired based on the old knowledge in the mother tongue. This is shown also in other studies, for example with Turkish bilingual children, that the knowledge in mother tongue helps learning a new language.
The Acquisition of Negation in Modern Standard Arabic by Bilingual Moroccan Children
Authors: Lahbibi Khalid , Yeou Mohamed 
Published: April 2024

Introduction. The present study reports results from grammaticality judgment and picture description tasks with 24 bilingual child learners of Modern Standard Arabic (MSA) (and Moroccan Arabic), aged between 5;1 and 9;1. The study investigates the learners’ comprehension and production of the anaphoric la: ‘no’, verbal la, lan, lam, ma: ‘not’, and non-verbal lajsa ‘is not’. It also explores whether the complex MSA negation delays the age of acquisition of the anaphoric, verbal, and non-verbal structures.
Results. Results suggested that the learners’ comprehension of negation was more robust compared to production, indicating processing difficulties associated with production of the complex MSA negation. The analysis of error patterns showed that children overutilized the anaphoric la: ‘no’ to avoid more complex structures. Interestingly, the development of negation was non-linear, displaying a U-shaped learning curve.
Conclusion. The current study examined negation in the comprehension and production of Moroccan child learners of MSA. First, in line with prediction, the complex structure of MSA negation was found to delay the development of the targeted negation structures. Second, the participants’ comprehension of MSA negation was more robust compared to production. This could be explained by difficulties in the implementation of grammatical knowledge. Third, reporting individual results, the study suggested that the child learners of MSA showed a non-linear pattern of negation acquisition, displaying a U-shaped learning curve. Finally, further research is needed to investigate MSA properties because it would provide valuable test cases for various important questions in linguistic theory and language acquisition, including our understanding of the nature, development, representation, and processing of MSA.
Secular and religious in modern Europe

Общественная дискуссия о границах и формах секулярного и религиозного в современном обществе является постоянным способом установления этих границ. Рассмотрев новые (переводные и оригинальные) издания на эту тему, можно сделать вывод о стремлении современных специалистов, с одной стороны, избежать концепта «христианского государства», а с другой — найти место религии как социального института в современном мире.
Public discussion about boundaries and forms of secular and religious in modern society is a constant way of establishing these boundaries. Having considered new (translated and original) editions on this topic, we can conclude about the desire of modern specialists, on the one hand, to avoid the concept of the "Christian state," and on the other, to find the place of religion as a social institution in the modern world.
