Earlier misidentifications of ammonites from Busot (SE Spain) led to two incorrect hypotheses regarding calpionellids, which are today attributed to the Calpionellopsis Zone (D) of the upper Berriasian. The first hypothesis suggested that some calpionellid species survived into Hauterivian times, while the second hypothesis proposed that these calpionellids were reworked into Hauterivian strata. However, the revision of the ammonitic material collected in 1993-1994, along with the study of new material collected in 2024, suggests a late Berriasian age, as the ammonite assemblages likely correspond to the Fauriella boissieri and Tirnovella alpillensis Standard Ammonites zones. Nannofossil assemblages and the presence of Octahedronoides tethysianus further support this dating. This reassessment calls for a reexamination of claims regarding the occurrence of calpionellids in strata younger than the Valanginian in the literature.
Merging Minds: A Critical Analysis of Hybridizing Islamic Education and Neuroscience
Authors: Jailani Jailani
Published: December 2024

The dichotomy between neuroscience and Islamic Education has led to sluggish scientific progress and the emergence of unresolved issues. Islamic education, rooted in divine revelation, relies on reason as its foundation—a realm extensively studied in neuroscience. This research aims to investigate the potential of integrating neuroscience and Islamic Education, giving rise to the scientific field of Islamic Education Neuroscience. The study employs a qualitative literature-based approach, analyzing various theories and adopting a grounded theory methodology to shape the research objectives. The findings reveal that Islamic Education Neuroscience, encompassing the epistemology of Islam, including bayani, irfani, and burhani traditions, already exhibits scientific validity due to existing studies. However, further scientific development necessitates internalizing scientific theories, substantiating them within the epistemology of Islamic Education, and fostering integration with other Islamic education disciplines. This research holds significant implications for achieving the comprehensive goals of Islamic education, harmoniously bridging the gap between general science and Islam. The envisioned scientific development of Islamic education presents a framework for deeper understanding and practical application of knowledge, in alignment with Islamic principles, contributing to human progress.

Islamization of Natural Sciences
Authors: Eddine Dadach Zin
Published: December 2024

Islamic science, grounded in the Holy Quran and the Sunnah, thrived for over twelve centuries before facing cultural and civilizational crises in the early nineteenth century. By the early twentieth century, the decline peaked with the fall of the Ottoman sultanate and the division of Muslim lands by European powers. Modern Western civilization, shaped by the Renaissance and Enlightenment, prioritized scientific inquiry, empiricism, and freedom, but was also rooted in atheism, agnosticism, nihilism, and ethical relativism. This led to significant progress during the Industrial Revolutions. While the West celebrated scientific advancement, the Muslim world struggled to keep pace, resulting in an inferior position during interactions with the West. The 20th century introduced modern science to the Islamic world, facilitated by expanded education systems, such as the universities in Istanbul and Cairo established in 1900 and 1925. This led to challenges, including naturalism and social Darwinism, which conflicted with Islamic beliefs. Efforts to harmonize science with Islam resulted in diverse viewpoints among Muslim scholars. Nonetheless, the Muslim world’s scientific progress remains limited, as evidenced by low scientific output, research expenditures, and the number of researchers and engineers, highlighting concerns about contemporary scientific illiteracy.

Published: December 2024

Multiple-choice tests are commonly used in education, including at the higher education level, as an efficient method for evaluating students' understanding. In the context of Arabic language learning, multiple-choice tests are believed to be able to assess students' level of comprehension and mastery of the language. However, it is essential to evaluate the feasibility and reliability of these tests to ensure that the results accurately reflect students' abilities. This study aims to evaluate the feasibility and reliability of multiple-choice tests in Arabic in higher education. The evaluation was conducted by assessing content validity, construct validity, reliability, and correlation with students' academic performance. The results showed that 60% of the test questions were aligned with the existing curriculum, although only 14 out of 25 questions met the criteria for construct validity. Despite some shortcomings in construct validity, the test demonstrated a high level of reliability, with a Cronbach's Alpha value of 0.88, indicating consistent test results. Additionally, there was a significant positive correlation between test scores and students' academic performance (r = 0.44), indicating that the test can reflect students' overall academic achievement. Despite certain limitations in construct validity, the conclusion of this study is that the multiple-choice test is still considered reliable as an evaluation tool. This conclusion provides insight into the test's effectiveness in measuring students' understanding and mastery of Arabic at the tertiary level.

Causal associations between 26 musculoskeletal disorders and gut microbiota: A Mendelian randomization analysis with Bayesian validation
Authors: Wang Yunhao , Sun Yingze , Liao Hongxing
Published: December 2024

Emerging evidence suggests that gut microbiota imbalances may influence the onset of musculoskeletal disorders (MSDs), yet conclusive evidence establishing causation remains limited. This study investigates the causal relationship between gut microbiota and a range of MSDs, aiming to identify potential therapeutic targets. Using data on 211 gut microbiome taxa from a genome-wide association study (GWAS) and summary statistics for 26 MSDs from the Finnish Biobank, we employed Mendelian randomization (MR) with inverse-variance weighting (IVW) as the primary analytical approach, complemented by Bayesian model validation to ensure robust results. Our MR analyses revealed significant causal associations between gut microbiota and nine MSDs within four categories, including osteoporosis (IVW-Beta = 0.011, P = 0.025), rheumatoid arthritis (IVW-Beta = -0.016, P < 0.001), rotator cuff syndrome (IVW-Beta = -0.007, P = 0.022), and calcific tendonitis of the shoulder (IVW-Beta = -0.021, P = 0.034). Bayesian validation underscored the plausibility of these relationships, supporting the potential causal role of gut microbiota in the development of these disorders. Our findings present a library of causal associations that underscore the gut microbiome's role in MSD pathogenesis, providing genetic evidence that highlights specific gut microbiota taxa as prospective therapeutic targets. This research offers novel insights into the pathogenic mechanisms underlying MSDs and points toward new directions for future investigation into microbiome-based therapies.

El libro Phenomenology of the Icon: Mediating God through the Image de Stephanie Rumpza, con prefacio de Jean-Luc Marion, explora cómo el ícono bizantino actúa como medio para mediar la trascendencia divina, integrando fenomenología, teología y estética cristiana. Rumpza se basa en la hermenéutica de Hans-Georg Gadamer y la fenomenología de Marion para distinguir entre ídolo e ícono, argumentando que el ícono, lejos de ser un simple objeto visual, permite una experiencia de lo divino al desbordar las limitaciones de la percepción humana. La autora también destaca la importancia del contexto litúrgico para comprender el ícono como una ventana hacia lo invisible, y muestra cómo este enfoque fenomenológico enriquece la comprensión teológica de lo sensible como puerta hacia lo trascendente, evitando tanto la idolatría como el iconoclasmo.

Coupled differential-algebraic equations framework for modeling six-degree-of-freedom flight dynamics of asymmetric fixed-wing aircraft
Authors:   College of Engineering, University of Buraimi, Al Buraimi, Oman, Marzouk Osama A.
Published: December 2024

This study presents a comprehensive mathematical framework for modeling the flight dynamics of a six-degree-of-freedom fixed-wing aircraft as a rigid body with three control surfaces: rudder, elevators, and ailerons. The framework consists of 35 differential-algebraic equations (DAEs) and requires 30 constants to be specified. It supports both direct and inverse flight dynamics analyses. In direct dynamics, the historical profiles of control inputs (deflection angles and engine thrust) are specified, and the resulting flight trajectory is predicted. In inverse dynamics, the desired flight trajectory and an additional constraint are specified to determine the required control inputs. The framework employs wind axes for linear-momentum equations and body axes for angular-momentum equations, incorporates two flight path angles, and provides formulas for aerodynamic force and moment coefficients. Key advantages include improved computational efficiency, elimination of Euler angle singularities, and independence from symmetry assumptions with regard to the aircraft’s moments of inertia. The model also accounts for nonlinear air density variations with altitude, up to 20 km above mean sea level, making it suitable for accurate and efficient flight dynamics simulations.
Cyberspace – Threats to Young People and the Family
Authors: Podkowińska Monika
Published: December 2024

Cyberspace is an important communication area that can be considered both from the perspective of external and internal (family) communication. One can also look at this space of communication from the perspective of threats and opportunities for the family and young people. The article was based on non-reactive research techniques, mainly on the analysis of existing data. The author, based on the literature on the subject and the results of nationwide research on the use of the Internet by young people (“Teenagers 3.0,” 2021; “Teenagers 3.0,” 2023, “Teenagers towards digital pornography,” 2022 reports. NASK-PIB), raises the issue of threats related to cyberspace in the context of family and family communication. The author also pays attention to the features of virtual communities, presents communication threats related to young people’s entry into the world of the Internet and cyberspace, and points to the challenges that modern families come up against in the face of these threats. The presented research results indicate many discrepancies in how parents and children perceive the rules regarding the use of the Internet and the threats related to cyberspace. In a situation where there is no open communication in the sphere of family communication, problems resulting from young people using the Internet inappropriately are hidden in silence. This poses an important challenge for modern families.
Magnetoelastic properties in isotropic magnetic elastomers
Authors: Musikhin A. Yu. , Zubarev A. Yu.
Published: December 2024

Purpose. To investigate the influence of magnetic field on the elastic characteristics of isotropic magnetic elastomer.

Methods. The behavior of magnetic particles in the sample was studied based on the idea of a hierarchical model of chain formation combined with a lattice model of particle arrangement. When studying systems with chain aggregates, a statistical distribution function was introduced for the number of particles in a chain, which made it possible to calculate the number of chains in a composite with a given particle concentration. The nonlinear magnetization of particles in the sample was modeled in the form of the semi-empirical Frohlich-Kaenely law, which made it possible to calculate the magnetization of materials with good accuracy, both in weak and strong magnetic fields.

Results. The paper presents a model describing the elastic properties of an isotropic magnetic elastomer synthesized without the effect of a magnetic field. The elastomer consists of particles with a volume concentration of 28.6%, capable of magnetization, the size of which is 10 microns. These particles are embedded in a polymer matrix. Under the action of a magnetic field, chains of magnetic particles are formed in the polymer. It is assumed that the length of such chains is less than the size of the sample in the direction of the field. The dependences of the shear modulus of the composite on the external magnetic field are determined.

Conclusion. A physical model is proposed that successfully predicts the magnetorheological effect in the studied composite material with a soft matrix and randomly distributed particles synthesized without a magnetic field. The research is based on an improved lattice theory that takes into account the probabilistic distribution of particles due to the polymerization process of the composite. A hierarchical principle of forming particle chains is proposed, where their number doubles at each stage. It has been established that chains of such length make the main contribution to the macroscopic shear modulus of the composite. The agreement between theoretical results and experimental data confirms the adequacy of the proposed model for describing the behavior of a magnetic elastomer in an external magnetic field.

Published: December 2024

Purpose of the study. To characterize the size composition, atomic and electronic structure, and antioxidant activity of Cerium dioxide nanoparticles synthesized by the hydrothermal method in an autoclave.

Methods. Cerium dioxide nanoparticles were synthesized in an autoclave at 150°C. The size composition of the nanoparticles was characterized by small-angle X-ray scattering diffractometry. The structural and phase composition was studied using X-ray diffractometry. Scanning electron microscopy with an energy-dispersive X-ray analysis attachment was used to analyze the elemental composition of the samples. Antioxidant activity was studied in the photochemical degradation reaction of methylene blue dye under irradiation with a diode source with a wavelength of 660 nm. The residual concentration of methylene blue in the process of photodegradation was determined using spectrophotometry.

Results. Pure Cerium dioxide nanoparticles measuring 10-25 nm were synthesized using hydrothermal synthesis in an autoclave at 150°C. In the presence of the obtained cerium dioxide nanoparticles, the process of photodegradation of the methylene blue dye under the influence of red laser radiation slows down by 80%. The addition of ammonium citrate-stabilized Cerium dioxide nanoparticles leads to a slowdown in the process of photodegradation of methylene blue under irradiation with red light due to antioxidant activity, which increases with increasing concentration of nanoparticles. Maximum antioxidant activity is manifested at a molar ratio of ammonium citrate to CeO2 of no more than 2:1.

Conclusion. The hydrothermal synthesized CeO2 nanoparticles stabilized by ammonium citrate exhibit pronounced antioxidant activity. The results obtained can be used to develop selective antitumor photosensitizers based on Cerium dioxide nanoparticles.

Published: December 2024

The purpose of the study of this article is to identify the effect of laser treatment modes on the color of the steel 04X18H10.

The research methods were reduced to determining ranges for each of the parameters with an example of the desired color. The influence of laser radiation parameters: the power and frequency of laser radiation, the speed of the laser beam, the resolution of the fill of the marked object - contributes to obtaining a certain shade of the color palette according to the RAL standard.

The result of the study was the data obtained, according to which it is safe to say that the speed of movement of the laser beam has a direct effect on the resulting semitone color. At high values of this parameter, the colors become closer to dark halftones, whereas a decrease in speed leads to the opposite effect, it is possible that at low speeds of the laser beam, a slower heating of the object occurs, which leads to light halftones, and with a gradual increase in speed and, accordingly, a possible increase in surface heating temperature, colors begin to form a dark tone. The results obtained by changing the fill resolution parameter make it clear that an increase in this indicator directly affects the saturation of the resulting color with its increase, whereas a decrease in the number of fill lines causes a drop in the color saturation of the marked object.

Conclusion. In this paper, the influence of the factors responsible for obtaining various shades of colors during laser marking of metal is considered, a basic palette of colors is obtained for its subsequent expansion and use for artistic purposes.

Methods

In this cross-sectional pilot study, 12 study participants with upper extremity pain and/or weakness underwent strength evaluations for four upper extremity movements using in-person, telehealth, VIRTEPEX, and composite (telehealth plus VIRTEPEX) assessments. The evaluators were blinded to each other’s assessments. The primary outcome was feasibility, as determined by participant recruitment, study completion, and safety. The secondary outcome was preliminary evaluation of inter-rater agreement between in-person, telehealth, and VIRTEPEX strength assessments, including κ statistics.

Results

This pilot study had an 80% recruitment rate, a 100% completion rate, and reported no adverse events. In-person and telehealth evaluations achieved highest overall agreement (85.71%), followed by agreements between in-person and composite (75%), in-person and VIRTEPEX (62.5%), and telehealth and VIRTEPEX (62.5%) evaluations. However, for shoulder flexion, agreement between in-person and VIRTEPEX evaluations (78.57%; κ=0.571, 95% CI 0.183 to 0.960) and in-person and composite evaluations (78.57%; κ=0.571, 95% CI 0.183 to 0.960) was higher than that between in-person and telehealth evaluations (71.43%; κ=0.429, 95% CI −0.025 to 0.882).

Conclusions

This study demonstrates the feasibility of asynchronous VIRTEPEX examinations and supports the potential for VIRTEPEX to supplement and add value to standard telehealth platforms. Further studies with an additional development of VIRTEPEX and larger sample sizes for adequate power are warranted.

Background

Research supports the use of mobile phone apps to promote medication adherence, but the use of and satisfaction with these apps among medically underserved patients with chronic illnesses remain unclear.

Objective

This study reports on the overall use of and satisfaction with a medication adherence app (Medisafe) in a medically underserved population.

Methods

Medically underserved adults who received care for one or more chronic illnesses at a federally qualified health center (FQHC) were randomized to an intervention group in a larger randomized controlled trial and used the app for 1 month (n=30), after which they completed a web-based survey. Objective data on app usage were provided as secondary data by the app company.

Results

The participants were very satisfied with the app, with all participants (30/30, 100%) somewhat or strongly agreeing that they would recommend the app to family and friends. Participants strongly agreed (28/30, 93%) that the reminders helped them remember to take their medications at the correct time each day, and they (28/30, 93%) found the app easy to use. Additional features accessed by some included educational features and the adherence report. Participants noted the helpfulness of having a medication list on their phones, and some used it during medication reconciliation at doctor visits. Use of the Medfriend feature, which alerts a social support person if a medication is missed, was low (n=2), but those who used it were very positive about the feature.

Conclusions

A commercially available medication adherence app was found to be useful by participants, and they were satisfied with the app and the additional features provided. The use of medication adherence mobile phone apps has the potential to positively influence chronic disease management in a medically underserved population on a large scale.

Experimental Studies into the Super Finishing of Nitronic-60 by One - Way Extrusion Honing Process
Authors: B P Sreenivasa Murthy , P Prasad , B Thimmegowda M
Published: December 2024

Abstract: The surface requirements of engineering components used varies widely depending on where the components surface
is being applied for. Fabrication of surfaces with desired characterises on materials possessing high hardness is the need of the
hour to effectively overcome the contemporary application challenges. The required surface generation of these difficult to cut
material possessing intricate and unable to reach geometries could not be met by conventional finishing processes. So, several
non-conventional finishing processes have been developed over the years to meet the ever-growing requirements of the industry,
among them, Extrusion Honing or Abrasive Flow Machining where a flexible media loaded with abrasive particles acting as
cutting tool can be successfully used to fine finish the surface.
In the present study, the abrasive loaded flexible cutting media is extruded using one-way extrusion honing process and the
effect of this on the surface characterises of Nitronic-60 is studied. The surface roughness is examined using a stylus type
surface measuring instrument and the surface texture of the specimen before and after the process is analysed using SEM
images. The results shows a significant enhancement in surface finish using EH/AFM process and the process found quite
capable in removing the surface irregularities and producing surface with enhanced overall surface integrity.

Abstract: In recent-years, blockchain has received increasing attention and numerous applications have emerged from this
technology. A renowned Blockchain application is the cryptocurrency Bitcoin, that has not only been effectively solving the
double-spending problem but also it can confirm the legitimacy of transactional records without relying on a centralized system
to do so. Therefore, any application using Blockchain technology as the base architecture ensures that the contents of its data
are tamper-proof. This paper uses the decentralized Blockchain technology approach to ensure that consumers do not fully rely
on the merchants to determine if products are genuine. We describe a decentralized Blockchain system with products anticounterfeiting, in that way manufacturers can use this system to provide genuine products without having to manage directoperated stores, which can significantly reduce the cost of product quality assurance
An Investigation on the Laser Abrasive Jet Machining of glass using Taguchi L27 arrays

Published: December 2024

Abstract: Nowadays, it might be challenging to machine materials that are difficult to cut. The main issues with machinability
are high cutting powers, poor surface quality, and short tool lives. Traditional machining techniques have been shown to be less
efficient and time- consuming. Nowadays, it might be challenging to machine materials that are difficult to cut. Nowadays,
researchers are choosing hybrid machining techniques to solve these issues. The laser-assisted machining approach has drawn
attention recently among other techniques. The cutting of difficult-to-cut materials with the aid of lasers can improve the
machinability of those materials. Heat assistance is provided by a low power CO2 laser, and a HYBRID non- conventional
machining technique is created by combining CO2 laser machining with an abrasive jet approach. In the aforementioned study,
two unconventional machining techniques are used to evaluate the process variables, performance traits for a better material
removal rate, and surface roughness. This work summarises the machining process for the machining of challenging materials
using laser assistance.
