Le Pin à crochets Arverne, ou l’indigénat de Pinus uncinata Ram. dans les montagnes d’Auvergne
Authors: Cantegrel Renaud , Renaux Benoît , Lathuillière Laurent
Published: December 2023

Les tourbières boisées du Massif central participent à divers habitats prioritaires du réseau Natura 2000. Or quatre d’entre elles comportent du Pin à crochets, considéré comme anciennement introduit d’après certaines analyses polliniques. À l’issue d’une approche pluridisciplinaire les auteurs apportent la preuve de l’indigénat de Pinus uncinata sur les tourbières de la Barthe (monts Dore) et de la Pigne (monts du Forez). Ils prouvent à l’inverse que le Pin à crochets n’apparaît sur les stations tourbeuses de Margeride qu’au milieu du XXe siècle par ensemencement naturel à partir d’anciens boisements artificiels situés à la périphérie des sources du Pontajou (Haute-Loire) et de la Fouon de la Bique (Lozère).
Messages clés :• Les tourbières boisées à Pinus uncinata ne constituent pas toutes des habitats naturels dans le Massif central.• Différentes investigations et archives prouvent l’indigénat du Pin à crochets seulement sur les tourbières de la Barthe (monts Dore) et de la Pigne (monts du Forez).
THE ONTOLOGICAL CAPTURE OF REASON AND REVELATION
Authors: Alkadzim Musa
Published: December 2023

Reason and revelation are a topic that is debated by many parties to determine the position and superiority between reason and revelation. There are differences of opinion among thinkers regarding the position of reason and revelation. This debate has also attracted the attention of many Islamic thinkers, including Islamic philosophers. This paper explores the ontological capture of reason and revelation debate by two of the most prominent Sufi philosophers, Ibn ‘Arabī and Mullā Ṣadrā. This research employs a literature review as a research methodology, with an emphasis on synthesis and integration. Through this research, it can be concluded that Ibn ‘Arabī’s and Mullā Ṣadrā’s ontological perspectives have deconstructed theological and epistemological disagreements between rationalists who place reason above revelation and their traditionalist opponents. Ibn ‘Arabī’s theory of creative imagination unveils the ontological order of reason and revelation, whereas Mullā Ṣadrā’s theories of tashkīk (gradation of being) and the union of the knower and the known during the production of knowledge (or to be more precise, the union of intellect and intelligible during intellection) consistently place reason and revelation not in opposing sides but rather in a single gradational existence. Both Ibn ‘Arabī and Mullā Ṣadrā have broken the theological and epistemological vicious cycle by introducing ontological interventions into the debate. Ibn ‘Arabī and Mullā Ṣadrā may or may not have intended to participate in the polemic; as a result, these outcomes were rarely mentioned in the historical context of the ideas.

Authors: Bhardwaj Laxmi Kant , Rath Prangya , Tokas Rajat
Published: December 2023

Information and telecommunications technology (ITT) have expanded into many aspects of modern life and have positively affected human life even in the most remote areas of developing countries. The rapid growth in ITT has led to an improvement in the capacity of computers but simultaneously to a decrease in the product’s lifetime as a result of which increasingly large quantities of e-waste are generated annually. It contains hazardous components that if it is not properly managed, can have adverse environmental and health effects. The management of e-waste poses significant challenges in developing countries. Due to the lack of adequate infrastructure, e-waste is burned or dumped in open areas. Informal and inefficient recycling practices are generally employed which further exacerbate pollution and health risks. So, the implementation of e-waste management, adequate recycling, and waste disposal facilities have become crucial concerns. This article reviews the concept of e-waste generation, challenges, disposal, and its impact on human health & environment in detail.

Published: December 2023

The prevalence of allergic diseases, including food allergy, is increasing, especially in developed countries. Implementation of an elimination diet is not a sufficient therapeutic strategy in patients with food allergy, whose quality of life is significantly impaired. In recent years, new effective therapeutic strategies have been developed, such as the application of oral, sublingual, and epicutenous immunotherapy. Oral immunotherapy is the most often applied strategy because of its effectiveness and ease of application, with an acceptable safety profile. The effectiveness of oral immunotherapy in patients with egg, cow's milk and peanut allergy has been proven both in terms of raising of the threshold and the development of tolerance, and in some patients, the development of sustainable unresponsiveness. Although oral immunotherapy is an effective treatment for food allergy, several limitations, including long duration and a significant rate of reported adverse events, reduces its success. Therefore, new therapeutic options, such as treatment with biologicals, either as combinations with food allergen immunotherapy or as monotherapy with the aim of improving the efficacy and safety of treatment are being investigated..

Published: December 2023

Natural gas plays a significant role in Tunisia's energy mix. Tunisia imports 66% of natural gas (NG) from Algeria (ANG), and the rest is provided by local gas fields mainly Miskar gas (MNG). To counteract this deficit, the Power-to-Gas approach emerges as a promising solution, given Tunisia's abundant renewable energy resources. By blending green hydrogen into the NG network, it is possible to (i) address the current energy crisis, (ii) lower the carbon intensity of the gas grid, and (iii) encourage sector coupling through the use of various renewable energy sources. This study presents an overview of various interchangeability indicators and investigates accordingly the allowable ratios for hydrogen blending with two types of natural gas distributed in Tunisia (ANG and MNG). It also explores the impact of hydrogen injection on the energy content variation and various combustion parameters. The results confirm that both ANG and MNG can withstand a maximum hydrogen blend of up to 20%. The article concludes with recommendations for further experimental testing of the findings and emphasizes the need to look into infrastructure and safety requirements with regards to the Natural gas network in Tunisia. This research serves as a critical step towards harnessing the potential of green hydrogen in Tunisia.
Gender and Law, an Intercultural Approach on Laws When They Aim at Ruling Women’s Body
Authors: FRACCHIOLLA Béatrice
Published: December 2023

This work is the result of a two-year research leave (French CNRS delegation) with field research in France, India and England, based on a total of 36 interviews in the three countries. The aim of this publication is to discuss how the laws of different countries deal with gender and what representations the laws reveal about gender roles in the societies they regulate through discourses. For example, France, England and India have laws that are more or less specific about gender roles in society: the language used to express the laws also fulfils gender roles while affecting people’s everyday lives. The whole issue of gender and rights is about the presumed and desired equality of rights for women and men, and the way in which this corresponds to the reality of women’s and men’s lives. Indeed, laws are necessary to regulate human relations in society. For example, anti-discrimination laws exist to protect and regulate these relationships in a common space, to regulate and combat abuse. The emphasis on gender – including gender roles – and LGBTQ+ people shows that this phenomenon is understood and experienced differently in global practice. Our examples in this publication focus on France and India.

Background: In America, vaccine-related deaths constitute a significant contributor to child mortality. An essential means of reducing this is through broad vaccine coverage. The COVID-19 pandemic has posed a potential disruption to vaccine coverage due to its effects on the healthcare system. Objectives: This study aims to evaluate the impact of the COVID-19 pandemic on DTP3 vaccination coverage in the Americas, investigating trends from 2012 to 2022 to identify significant changes, regional disparities, and the overall effect of the pandemic on progress towards global immunization targets. Methods: This study used the coverage data for the third dose of the Diphtheria, Tetanus, and Pertussis Vaccine (DTP3) pulled from UNICEF databases spanning 2012 to 2022. We conducted a JoinPoint regression to identify points of significant trend changes. The annual percentage change (APC) and 95% confidence intervals (95% CI) were calculated for America and its regions. We also used segmented regression analysis. Using the Chi-square test, we compared DTP3 vaccination coverage for each country between 2019 and 2022. Results: Overall, America saw a decrease in vaccine coverage during this period, with an APC of -1.4 (95% CI -1.8.; -1.0). This trend varied across regions. In North America, the decrease was negligible (-0.1% APC). South America showed the steepest decrease, with an APC of -2.5%. Central America also signif-icantly declined, with an APC of -1.3%. Our findings suggest a concerning trend of declining DTP vaccination rates in the Americas, exacerbated in certain regions, in the wake of the COVID-19 pandemic. The absolute decrease in vaccine coverage in the Americas was -4 % between 2019 and 2022, with the most significant drop observed in Central America (-7 %). However, six countries reported increased vaccination rates post-COVID-19, led by Brazil, with a 7% increase. Conversely, twenty-two countries registered a decline in DTP3 vaccine coverage, with the average decrease being -7.37%. This decline poses a significant challenge to achieving the WHO's target of 90% coverage for the third dose of DTP by 2030, as evidenced by the reduction in the number of countries meeting this target from 2019 to 2022.
Conclusions: The COVID-19 pandemic has impacted vaccine coverage in America, leading to a decrease, especially across Central America.

Authors: Kwon Min Ji , Lee Hyesu , Jung Ji Yoon , Yu Jae-Woong
Published: December 2023

The influences of doped hole transporting layer (HTL) on the performances of perovskite solar cells were studied. The influences of electrostatic and surface roughness effect by solvent additive doping were compared. The electrostatic effect of solvent additive doping was compared by addition of 1,8-diiodooctane and 1,8-dichlorooctane to the HTL layer. The surface roughness effect of solvent additive doping was examined using atomic force microscopy. The perovskite crystallinity by doping HTL was studied by X-ray diffraction. The conductivity of HTL was measured using four probe methods and was higher for doped devices. Enhanced conductivity of PEDOT:PSS film was also proved using fluorescence emission quenching. Long-term stability of the device was enhanced by doping HTL. The device with solvent additive exhibited much enhanced stability, retained over 80% of the initial PCE for 400 hours, while PCE of the device without solvent additive decreased to less than 80% after 200 hours. A very weak power microwave treatment was used for post-annealing of the fully fabricated devices. Post-annealing enhanced the lifetime of the device. Comparing different size of cells, the device lifetime was decreased as the cell area increased and as the size of the cell increased, the extent of lifetime enhancement by doping was increased.

Published: December 2023

Nerve agents have recently been used in battlefield operations, espionage wars and terrorist attacks. These compounds, like some pesticides, cause organophosphate poisoning. The rapid, non-contact detection of a sarin simulant has been demonstrated at the Diagnostics and Metrology Laboratory of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development using laser photoacoustic spectroscopy, an infrared absorption technology. The first measurements, carried out with an experimental system based on a quantum cascade laser and developed for the assessment of food authenticity in the “fingerprint region”, show that a detection limit of 1 nanolitre is within the reach of the instrument when chemometric analysis is applied.
Japanese Encephalitis: Risk of Emergence in the United States and the Resulting Impact
Authors: Monath Thomas P
Published: December 2023

Japanese encephalitis virus is a mosquito-borne member of the Flaviviridae family. JEV is the leading cause of viral encephalitis in Asia and is characterized by encephalitis, high lethality and neurological sequelae in survivors. The virus also causes severe disease in swine, which are an amplifying host in the transmission cycle, and in horses. US agricultural authorities have recently recognized the threat to the swine industry and initiated preparedness activities. Other mosquito-borne viruses exotic to the Western Hemisphere have been introduced and established in in recent years, including West Nile, Zika, and chikungunya viruses, and JEV has recently invaded continental Australia for the first time. These events amply illustrate the potential threat of JEV to US health security. Susceptible indigenous mosquito vectors, birds, feral and domestic pigs, and possibly bats, constitute the receptive ecological ingredients for spread of JEV in the US. Fortunately, unlike the other virus invaders mentioned above, an inactivated whole virus JE vaccine (IXIARO®) has been approved by the US Food & Drug Administration for human use in advance of a public health emergency, but there is no veterinary vaccine. This paper describes the risks and potential consequences of introduction of JEV in the US, the need to integrate planning for such an event in public health policy and the requirement for additional countermeasures, including antiviral drugs and an improved single dose vaccine that elicits durable immunity in both humans and livestock.

Depression is one of the most severe sequelae of COVID-19, with major depressive disorder often characterized by disruption in white matter (WM) connectivity , stemming from changes in brain myelination. This study aimed to quantitatively assess brain myelination in clinically diagnosed post-COVID depression using recently proposed MRI method, macromolecular proton fraction (MPF) mapping. The study involved 63 recovered COVID-19 patients (52 mild, 11 moderate, 2 severe) at 13.5±10.0 months post-recovery, with matched controls without prior COVID-19 history (n=19). A post-COVID depression group (PCD, n=25) was identified based on psychiatric diagnosis, while a comparison group (noPCD, n=38) included participants with neurological COVID-19 complications, excluding clinical depression. Fast MPF mapping revealed extensive demyelination in PCD patients, particularly in juxtacortical WM (predominantly occipital lobe and medial surface), WM tracts (inferior fronto-occipital fasciculus (IFOF), posterior thalamic radiation, external capsule, sagittal stratum, tapetum), and grey matter (GM) structures (hippocampus, putamen, globus pallidus, and amygdala). The noPCD group also displayed notable demyelination but with less magnitude and propagation. Multiple regression analysis highlighted IFOF demyelination as the primary predictor of PCD presence and severity according to Hamilton scores. The number of post-COVID symptoms was a significant predictor of PCD presence while the number acute of symptoms was a significant predictor of PCD severity. This study, for the first time, reveals extensive demyelination in numerous WM and GM structures in PCD, outlining IFOF demyelination as a key biomarker.

Published: December 2023

Hollow and concrete-filled steel tubes (CFSTs) are widely used as columns in many structural systems and local buckling can occur when they are subjected to axial compression loading. The critical regions for the local buckling of the columns are near the ends of the column where the moments are the highest. To strengthen the critical regions of the CFSTs the CFRP provides a simple and effective method which used previously as an enhancement for both of strength and ductility. So, this study suggests investigating the axial load behaviour of CFST strengthened with CFRP using FE method after a verification study and then a various parametric studies were carried out to cover the effect of the CFRP layers, number, confinement length and position. The FE results proved that, one CFRP sheet with thickness equal to 1.2 mm was strengthened the composite column by 8.5%, two CFRP sheets with total thickness equal to 2.4 mm was strengthened the composite column by 23.5%, three CFRP sheets with total thickness equal to 3.6 mm was strengthened the composite column by 35.1% and four CFRP sheets with total thickness equal to 4.8 mm was strengthened the composite column by 44.5%. Moreover, this study proved that by strengthened the composite columns with CFRP sheets with different lengths, the axial load resistance was improved by 8.5%, 4.6%, 0.1% and 0.0% for length percentages 100%, 75%, 50% and 25% respectively.
Constructability and Rigor of Angles Multiples of 3 in Euclidean Geometry
Authors: Kimuya Alex
Published: December 2023

This paper investigates the constructability of angles multiples of 3 within the framework of Euclidean geometry. It makes a significant contribution by presenting the first geometric construction for all such angles, offering a rigorous solution to a longstanding geometric problem. The paper reaffirms the efficacy of Euclidean geometry in providing precise constructions and robust proofs for these angles, demonstrating the enduring strength of Euclidean principles from classical to modern times. The presented workflow goes beyond Euclidean geometry to examine non-Euclidean methods, particularly analytical approaches, revealing misconceptions that compromise the genetic and geometric rigor of Euclidean principles. The paper exposes incongruities when algebraic proofs related to angle constructability are applied to the Euclidean system, emphasizing the misalignment of fundamental geometric concepts. A notable result in the paper is the construction of a angle, introducing the “ angle chord” as a novel geometric property. This property challenges assumptions made by non-Euclidean methods and highlights the nuanced geometric properties crucial for rigorous constructions. The paper refutes the fallacy of relying solely on algebra for solutions to angles multiples of , emphasizing the necessity of embracing Euclidean geometry for geometric discoveries. The paper underscores the merits and resilience of Euclidean geometry, showcasing its independence and depth across historical and modern perspectives. The newly presented geometric construction not only resolves a longstanding question but also emphasizes the intrinsic strength and uniqueness of Euclidean principles in contrast to alternative methodologies.

Published: December 2023

The plate heat exchanger (PHE) is a component that provides heat to be transferred from hot water to domestic cold water without mixing them with high efficiency. Over the lifetime of the PHE, cyclic pressures act on the brazing points and the plates, and this may lead to fatigue failure. The fatigue behaviour of the PHE, designed by using copper-brazed 316L stainless steel, was investigated in this study. First, the fatigue tests under the load ratio R = 0.1 were performed on the Vibrophore 100 testing machine to obtain the S-N curve of the analysed brazed joint. Based on the obtained experimental results, an appropriate material model of the analysed brazed joint has been created, which was validated with numerical calculation in the framework of a program code Ansys. A validated material model was then used for the subsequent numerical analysis of PHE. In order to carry out a numerical calculation using the finite element method (FEM), a 3D model of the heat exchanger was created based on the previous scanning of PHE-geometry. Thereafter, the geometry was parameterised, which allowed us to perform parametric simulations (monitoring different responses depending on the input geometry). Numerical simulations were carried out in the framework of the Ansys software, whereby the obtained results were analysed, and the responses were appropriately characterised according to previously determined load cases.

Published: December 2023

A single Cancer immunotherapy has ushered in a transformative era in oncology, bringing forth unprecedented promise and opportunities. However, even with its significant breakthroughs, the domain faces the continual issue of treatment resistance. Such resistance not only restricts the broad effectiveness of these pioneering treatments but also highlights the imperative need for further research. Delving into the complex world of cancer immunotherapy resistance, we identify a range of mechanisms, from primary and secondary resistance to the notable effects of genetic and epigenetic variables, and the pivotal importance of the tumor microenvironment (TME). Additionally, we emphasize the need for innovative strategies to mitigate this resistance, including combination treatments, customized immune checkpoints, and instantaneous monitoring. By advocating for these cutting-edge methods, we foresee a direction that incorporates personalized healthcare, enhanced treatment options, and a steadfast dedication to the welfare of patients. Through a comprehensive and diverse approach, we aim to address the hurdles posed by resistance, elevating cancer immunotherapy as a symbol of hope for patients worldwide.

The article presents the results of evaluating the possibility of conducting radio astronomy studies in the windows of atmospheric transparency ~100, ~230 and ~350 GHz using the optical Big Telescope Alt-Azimuthal (BTA) of the SAO RAS. A list of some promising astronomical tasks is proposed. The astroclimat conditions at the BTA site and possible optical, cryogenic and mechanical interfaces for mounting a superconducting radio receiver at the focus of the optical telescope are considered. As a receiving system, arrays of detectors cooled to ~0.3 K based on the Superconductor – Insulator – Normal metal – Insulator – Superconductor (SINIS) structure are proposed. The implementation of the project will make it possible to use the BTA site of the SAO RAS not only to solve some astronomical problems (it is possible to consider the implementation of a single observatory, the VLBI mode in the Suffa, EHT and Millimetron projects), but will also be used to test various cryogenic detectors in a real observatory.
Efficient Electromagnetic Scattering Modeling from Composite Dielectric-Metal Targets
Authors: Hua Mengbo , He Siyuan
Published: December 2023

To address the challenges associated with the difficult electromagnetic (EM) scattering computations of anisotropic dielectric-coated metallic composite targets, we proposed an efficient hybrid algorithm for simulating the EM scattering of complex targets with anisotropic dielectric coatings. This method, based on Impedance Boundary Condition (IBC), utilizes surface impedance vectors to describe the EM properties of the dielectric. It fully leverages the respective advantages of the low-frequency Method of Moments (MoM) and the high-frequency Physical Optics (PO) to achieve high-precision and rapid EM simulation of anisotropic dielectric-coated metallic composite targets. Employing boundary conditions and equivalent principles, we equivalently transform the EM scattering problem of targets with thin dielectric coatings into the radiation problem of equivalent EM current on impedance surfaces. This enables the high-precision and rapid calculation of Radar Cross Sections (RCS) for complex targets with anisotropic dielectric coatings. Using examples such as a square plate structure, a simplified aircraft, and a complex satellite model, the simulation results exhibit a high degree of agreement with full-wave numerical solutions and demonstrate a significant advantage in computational resources. This research convincingly demonstrates the accuracy and effectiveness of the proposed method.

Published: December 2023

Two-phase flows consisting of liquids and gases are often found in everyday life and are used on an industrial scale. In an industrial environment, this flow has many weaknesses, including pressure drop and void fraction. One strategy to reduce losses that arise is to use passive methods. The passive method used is to utilize the shape of the grooves in the channel. In this study, the flow is used to determine its effect on the pressure drop and void fraction that appears in two-phase flow. The experimental method was used for this study. The test pipe is equipped with 16 grooves, while the smooth pipe (without grooves) is used as a comparison. The test pipe is made of acrylic material. The water fluid is circulated using a centrifugal water pump with a superficial speed of 0.33-0.42 m/s. Air fluid is supplied using a compressor with superficial speeds of 0.049, 0.066, and 0.082 m/s. Measurement of pressure drop was carried out using a pressure transmitter with an Arduino data logger. The void fraction is calculated by determining the ratio of the volume fraction of water and air in the test tube. The results of the study revealed that the use of 16 grooves in the pipe can reduce the pressure drop and cavity fraction that appears when compared to smooth pipes.

The current development model's accumulation logic has resulted in the emergence and consolidation of social processes like segregation, leading to differentiated access and availability of urban goods and services among social groups based on socioeconomic, ethnic, or societal standing. The current development model's accumulation logic has resulted in the emergence and consolidation of social processes like segregation, leading to differentiated access and availability of urban goods and services among social groups based on socioeconomic, ethnic, or societal standing. This disparity impacts employment levels, educational performance, urban decay, and environmental degradation. In this context, the article aims to examine the socio-spatial segregation in the access to socio-environmental amenities provided by public green spaces (EVP) in a medium-sized city, specifically Durango, Mexico. The analysis utilizes spatial analysis and statistical methods that involve five variables associated with EVPs: surface area, percentage, number, density, and the socioeconomic level of the population. A spatial pattern of segregation was identified through these variables, resulting in four clusters that impact how the city of Durango is inhabited, produced, reproduced, lived, and constructed.

Grande es la pasión que nace del decaimiento público: disputas de preeminencia y estratégias de ascenso de los embajadores de la monarquía hispánica en Francia. 1585-1593
Authors: Miranda Marcella
Published: December 2023

El objetivo de ese estudio es desarrollar un breve análisis sobre los casos concretos de disputas de preeminencia y estrategias de ascenso entre los ministros de Felipe II en Francia, entre 1585 y 1593. El intento es ilustrar el papel de la dinámica de las competencias entre actores de distintos estamentos en la consolidación de la diplomacia en la época moderna. La correspondencia de los agentes con el rey revela los bastidores de esas disputas, a la vez que pone de relieve las estrategias empleadas para imponer sus prerrogativas sobre los otros. Vamos a interpretar la práctica epistolar de los ministros, teniendo en cuenta sus trayectorias anteriores al año de 1593, cuando ocurre la reunión de los Estados Generales en París. El conflictivo e incierto contexto de la intervención de España en las guerras de religión en Francia creó un espacio propicio para la búsqueda de protagonismo político. Era la oportunidad perfecta para ofrecer la prestación de servicios al rey con el afán de conquistar, garantizar y aumentar el honor y prestigio de su familia.

Bu çalışmada, küresel ekonomide gelecekte önemli ekonomik güç olabilecek Çin, Rusya ve Brezilya ülkeleri arasında getiri ve volatilite yayılımı, Koutmos (1996) tarafından önerilmiş olan çok değişkenli VAR-EGARCH modeli ile incelenmiştir. Çalışma, 01/11/2012-18/11/2022 dönemine ait 2621 adet günlük veriden oluşmaktadır. Elde edilen bulgulara göre, Brezilya piyasasından Çin piyasasına yaklaşık %13,4 ve Brezilya piyasasından Rusya’ya piyasasına yaklaşık %15,0 düzeyinde getiri yayılımı mevcuttur. Elde edilen bu oranlar, Brezilya’dan diğer iki ülkeye getiri yayılımının yüksek olduğunu göstermektedir. Brezilya’dan Rusya’ya volatilite yayılımı yaklaşık %4,5 ve Brezilya’dan Çin’e yaklaşık %1,5 düzeyinde elde edilmiştir. Bu sonuçlar, Brezilya’dan diğer iki ülkeye getiri yayılımında olduğu gibi volatilite yayılımının simetrik değil asimetrik yayılım olduğunu göstermektedir. Ayrıca, Brezilya’nın Çin ve Rusya’ya volatiliteyi veren; Çin’in ise Rusya ve Brezilya’dan volatiliteyi alan piyasalar olduğunu sonucuna varılmıştır. Öte taraftan, olumsuz haberlerin olumlu haberlere göre etkisini gösteren asimetrinin göreceli önemi yüksek olan piyasalar sırasıyla Rusya (3,21); Brezilya (2,89) ve Çin (2,58) olduğu tespit edilmiştir.

This paper is titled "Linguistic Structuralism as a Contemporary Interpretative Approach." The research presented in this paper is conducted using a library research model and is presented in a descriptive-analytical framework. It seeks to describe the language analysis methods used by some Islamic scholars as approaches to reading the Quran. The method in question is Linguistic Structuralism, which was developed by Ferdinand de Saussure. Linguistic Structuralism, originally a study of pure language, has found its place as an analytical tool in the hands of Islamic scholars. This linguistic study attempts to uncover meanings and significances that give rise to a "new" meaning, a meaning represented by the text itself. Two scholars who explicitly apply several aspects of linguistic structuralism in their Quranic readings will be discussed: Muhammad Syahrur in "al-Kitāb wa al-Qur’ān Qirā’ah Muʻāṣirah" and Mohammed Arkoun in "Lectures du Coran."

The Advancement of Agricultural Technology in Conjunction with the Modernization Wave: Not Only Progress and Convenience, but Also Confrontation with Agricultural Problems The progression of agricultural technology alongside the currents of modernization has yielded not only advancement and increased ease in human existence but has also precipitated a series of agricultural quandaries. From a philosophical vantage, the essence of technology resides in its framework, which perceives nature as an instrument amenable to human engineering. The process of technological development, or technification, within modern agriculture, is fraught with predicaments. Consequently, this exposition seeks to delve into these predicaments concerning the human perspective on both nature and its subsequent contextualization within the Islamic framework. The predicaments associated with technification in agriculture can be delineated into four salient facets. First, there is the concomitant technological worldview that accompanies it. Second, its predominant focus gravitates towards the resolution of "how to" inquiries. Third, it exhibits an orientation geared explicitly towards efficiency and sophistication. Lastly, it contributes to the attenuation of the sensory experiences of humans with regard to the natural world.

Psikoseksual Sigmund Freud merupakan teori yang cukup berpengaruh dalam menggambarkan kepribadian manusia di era kontemporer. Freud memandang bahwa gangguan kesehatan mental manusia (neurotic) itu dipengaruhi besar oleh pengalaman seksualnya di masa kecil. Besarnya pengaruh teori ini, di sisi lain teori ini ternyata memiliki banyak kecacatan secara metode ilmiah. Belum lagi, para psikolog Muslim menilai terdapat problem worldview dalam teori tersebut sehingga psikoseksual dianggap bertentangan dengan pandangan hidup Islam. Oleh karena itu, makalah ini bertujuan untuk melakukan rekontruksi terhadap Psikoseksual Freud berdasarkan pandangan hidup Islam (Islamic Worldview). Selanjutnya dilakukan proses Islamisasi untuk memasukan konsep-konsep manusia dalam Islam terhadap teori tersebut. Penelitian ini merupakan penelitian kepustakaan (library research) dan sumber data yang digunakan terdiri dari sumber data primer karya-karya Sigmund Freud dan sumber data sekunder yaitu berupa buku-buku, yang relevan dengan penelitian ini untuk memperkuat argumentasi serta untuk melengkapi data dari hasil penelitian. Teknik analisis data yang digunakan penulis dalam penelitian ini ialah analisis isi (content analisys). Adapun hasil temuan yang penulis dapatkan dari tulisan ini, psikoseksual memiliki problem secara epistemologis dan worldview yang tidak berkesesuaian dengan pandangan hidup Islam. Dengan demikian, proses Islamisasi terhadap teori tersebut merupakan suatu keniscayaan untuk menghilangkan unsur-unsur yang bertentangan dengan pandangan hidup Islam

. Currently, there is a tendency to diversify the generation of heat and electricity and to improve solid fuel technologies. These trends actualize the search for mathematical tools for describing and predicting the operation of apparatuses with a fluidized bed of dispersed fuel materials. However, since the mechanics of heterogeneous media (and dispersed media in particular) is to a certain extent in its infancy in relation to the mathematical foundations of modeling, it is often difficult to predict the operation of equipment. In particular, the poor quality of mathematical basis does not allow predicting the fields of concentrations and velocities of the phases of the fluidized bed, although this knowledge serves as the fundamental basis for calculating heat and mass transfer and chemical processes. In the present work, a computational and experimental study of the local hydromechanical characteristics of a monodisperse fluidized bed has been carried out. The mathematical apparatus of the theory of Markov chains was used as a basis for modeling. The tasks were solved in a one-dimensional formulation, which implied the division of the bed in height into cells of small but finite sizes. Fluidized bed phase distributions were described by state vectors whose evolution was controlled by transition probability matrices. The elements of these matrices were matched to the physical parameters of the processes. The model was verified by comparing the calculated predictions with the data of a full-scale experiment conducted as part of the study, aimed at measuring the local velocities of the gas phase inside the fluidized bed. The experimental data with a good accuracy for engineering calculations were described by the proposed model, which makes it possible to consider it as a reliable scientific basis for the computer method for calculating installations using the fluidization technique.

. Currently, the transition to alternative fuel during the operation of thermal power plants (TPP) occurs due to the reduction and unreliability of coal supplies, deterioration of its quality, proposals for the use of cheaper fuel, tightening environmental requirements. Alternative fuel means such coal, for the use of which the boilers have not been designed during their design or reconstruction, as well as coal that has not previously undergone industrial or experimental combustion at this TPP. When converting boilers to alternative fuels, the main problems are: slag of the furnace shields and heating surfaces located above the furnace; fouling of convective heating surfaces; instability of non-designed fuel combustion; abrasion of the convective part of boilers; reduction of environmental performance; change in operating conditions of dust preparation, slag removal, ash collection and fuel supply systems. Before conducting experimental combustion of alternative fuels, it is advisable to carry out a preliminary assessment of its combustion possibility using numerical simulation, which makes it possible to identify emerging problems in advance. The most important factor in assessing the possibility of using alternative fuels is the influence of thermal performance, fuel and ash characteristics on the slagging of heating surfaces in the furnace. For a long time, the ability of ash to slagging was determined by the results of a fusibility test by changing the shape of a pyramid of ash particles during its gradual heating to various states according to the specific temperatures, viz. the initial deformation temperature, the softening temperature, the hemispherical temperature. The fusibility test cannot predict the real situation that occurs during the boiler operation. In addition, it does not allow ranking coals according to their tendency to slagging, which is necessary for the preliminary selection of alternative coal. Therefore, it is proposed to use the Watt - Fereday method with Bomkamp’s refinement for calculating the slagging index for ranking coals according to suitability as non-design fuels.

The topic of research stands on heavy liquid metal coolants is currently undergoing a rebirth. Experimental stands have been built, for example, LILLA SCK CEN (Center for Nuclear Research in Belgium, Mol). This is one of the most famous stands that uses heavy liquid metal heat carriers. But a sufficiently complete description of the equipment line-up and the application of specific solutions for monitoring and maintaining the operability of the stands at the heavy liquid metal coolants is not published in the open press. Most likely, this is due to the specifics of research where there is a sufficient amount of secrecy. The aim of the work was to conduct a comprehensive review of various equipment use in this field. This will make it possible to plan more efficient composition of new research stands at heavy liquid metal coolants and avoid unnecessary mistakes when operating them. Heavy liquid metal heat carriers of nuclear power plants such as lead, eutectic lead-bismuth alloy, lead-lithium, gallium alloys differ significantly in their physicochemical properties from traditional and well-studied, widely used water, sodium, as well as liquid salt heat carriers, potassium, gases (helium, etc.).

Monitoring of air pollutions is one of actual trends in the development of industrial and domestic instrumentation. There are sets of tasks for improving gas analytical instruments because of increasing demand for control of a concentration of explosive and toxic gases on a level with maximum allowable concentration. The aim of the paper was to investigate the methods of formation and elemental composition of indium oxide films modified with tin oxide on the surface of gas sensor elements as one of the promising compounds for improving the detection efficiency of explosive and toxic gases in the environment. The processes of formation of gas-sensitive films deposited on the surface of nichrome alloy information electrodes were studied in this article. Substrates of anodic aluminum oxide with area of 10 × 10 mm2 and a thickness of 45 ± 0,5 μm were chosen for research. Two layers on the surface of the samples were formed. The first layer was formed from NiCr alloy (Ni – 80 %, Cr – 20 %) with a thickness of ≈ 0.3 μm by ion-plasma sputtering. The second layer was based on indium oxide with addition of tin oxide with thicknesses from ≈ 0.3 μm to ≈ 1.0 µm and coated with sol-gel technology. Five samples of gas-sensitive films were formed with different methods of deposition and heat treatment. Scanning electron microscopy was used for study of films’ morphology and elemental compositions of samples. The most perfect continuous semiconductor films were obtained by multilayer applying of a sol-gel paste. When semiconductor films were processed at annealing temperatures of 700 °C and higher in vacuum so there was observed cracking of semiconductor films up to a layer of NiCr alloy. The developed surface of gas-sensitive films allows to reach high sensitivity and affectivity of semiconductor sensors for control of air gas composition.
