PANDANGAN THABATHABA’I TENTANG IMPLIKASI POTENSI MANUSIA TERHADAP MISI FUNGSIONALNYA
Authors: Zakiy Ahmad , Ali Rijal
Published: June 2024

Kecanggihan ilmu pengetahuan dan teknologi di zaman sekarang ternyata belum benar-benar mampu menjawab mengenai persoalan asal usul kejadian manusia. Salah satu cara untuk mengisi kekosongan tersebut adalah dengan menggali ayat-ayat Al-Qur’an yang berkaitan dengan penciptaan. Ayat-ayat tersebut memiliki muatan yang filosofis, sehingga perlu dikaji dengan pendekatan filosofis agar mendapatkan pemahaman yang komprehensif dan mendalam, sebagaimana yang telah dilakukan oleh Muhammad Husein Thabathaba’i. Oleh karena itu, penelitian ini bertujuan menjelaskan dua hal, yaitu (1) bagaimana penafsiran Thabathabai terhadap QS. al-Baqarah [2]: 30 dan QS. al-Ahzab [33]: 72 (2) bagaimana pandangan Thabathaba’i tentang konsep penciptaan manusia. Ada dua sumber data yang digunakan dalam penelitian ini. Sumber data primer diambil dari Tafsir al-Mizan karya Thabathaba’i, sedangkan literatur lainnya, seperti buku dan artikel jurnal dijadikan sebagai sumber sekunder. Dengan menggunakan metode deskriptif analitis, penulis terlebih dahulu memaparkan penafsiran Thabathaba’i terhadap QS. al-Baqarah [2]: 30 dan QS. al-Ahzab [33]: 72. Hasil penafsiran tersebut kemudian dianalisis untuk melihat bagaimana pandangan dan pemahaman Thabathaba’i mengenai potensi manusia dan implikasinya terhadap misi fungsional penciptaan manusia. Penelitian ini menyimpulkan bahwa pemilihan manusia sebagai khalifah dan pemegang mandat al-amanah dari Allah Swt. dikarenakan keberadaan potensi dalam dirinya. Potensi ini pula lah yang membedakan manusia dengan makhluk lainnya seperti malaikat, gunung, bumi, dan langit. Adapun mandat tersebut merupakan ibadah yang berupa kehadiran hamba di hadapan Allah, rabb al-‘alamin, dengan penuh kerendahan diri dan penghambaan kepada-Nya, serta kebutuhan sepenuhnya kepada Tuhan Pemilik kemuliaan mutlak.

Recommending Probabilistic Approaches for Hypothesis Evaluation: A Gainful Extension of the Certainty Uncertainty Principle for the Social Sciences
Authors: Mandavilli Sujay Rao
Published: June 2024

This paper begins by reviewing our earlier and older paper on the certainty uncertainty principle which was published by us early in the year 2023, and by also examining its basic and fundamental postulates. We also then proceed to summarize our paper on racism and the ‘Comprehensive sociocultural persecution complex’ which was postulated as a logical extension and a practical application of the aforesaid certainty uncertainty principle for the social sciences. We also propose and examine other possible extensions of the certainty uncertainty principle such as the examination of the Flynn effect, the idea of qualified historiography, and the out of Africa theory, the multiregional hypothesis for the origin of anatomically modern humans, besides several others. We also present and propose a formula for attempting probabilistic approaches for hypothesis evaluation, and evaluate and recommend techniques for evaluating strength or weaknesses of evidence. We also correlate this paper with our various previous papers as necessary, and propose the principle and canon of non self-canceling contradictory evidence. We also hope and expect that this approach would not only constitute a logical extension of the certainty uncertainty principle, but also would be of some use in promoting the cause of rigorous and exacting science.

In the developing country, individuals are encountering numerous accidents. It would be undesirable. For any country to lose their lives for no reason is unacceptable. Railways are a type of transportation. crucial transports in India The crack must be manually detected. On the railway track, railway personnel are responsible for addressing this issue, even though. The inspection is conducted on a regular basis. Occasionally, the crack may go unnoticed. Due to There is a possibility of a train accident or derailment. This situation can be prevented by doing this. Automating railway crack detection has been suggested. This device emits sound waves that are higher than human hearing and detects the echoes that bounce back from objects. The railway track was monitored for any cracks by measuring the distance from the track to the ground. The microcontroller detects a crack if the sensor measures a distance larger than the set value. We are utilizing Arduino microcontroller. Upon identifying cracks or objects, the testing robotic vehicle halts and transmits its current longitudinal and latitudinal positions via SMS to both GSM and GPS at the control station. A new type of robotic car that uses IoT technology to detect cracks in railway tracks is a promising solution to improve the inspection of transportation infrastructure, making it safer and more reliable.
Temperature Controller of Infant Incubator using Arduino
Authors: Abbas Awfi Hussein
Published: June 2024

The factors affect the child within incubator are mainly the temperature, humidity. The organization of temperatures one of the basic criteria for building a stable environment for the child. This digital temperature controller uses an Arduino board as its primary controller. It can regulate any heating device's temperature within predetermined ranges and shows the device's status, including on and off, as well as its current temperature. A temperature controller is an instrument that regulates temperature, as the name suggests. The temperature controller receives data from a temperature sensor and outputs data to a control element, like a fan or heater. In order to regulate process temperature precisely and with minimal operator intervention, a temperature control system uses a controller that receives input from a temperature sensor (such as a thermocouple, RTD, or DHT22). After comparing the actual temperature to the set-point—the desired control temperature—it outputs the result to a control element.

Published: June 2024

The Emergency Service Locator (ESL) project describes a reformed system of emergency response that uses advanced localization technology. This paper presents some essential features of ESL such as exact identification of incident location, user-friendly interface, tracking incidents in real-time and co-ordination between different agencies. In addition, ESL incorporates two additional algorithms: one for detecting false emergency calls and another for identifying hit-and-run accidents. While greatly improving time management during emergencies as well as cooperation among responding organizations, ESL also poses privacy concerns and exposes the system to cyber-attacks due to its reliance on reliable networks. The adaptability to wearable devices is another aspect that makes this system more responsive. Therefore, it can be stated without any doubt that public safety will be improved significantly through implementation of such like systems but still there are challenges which need continuous improvement so that all people can benefit from them regardless of their abilities or locations.

Effective modelling and integrated spectral analysis approaches can advance modelling precision. To develop an integrated spectral forecast modelling of soil organic carbon (SOC), this research investigated a mining coal in Dengcao Coal Mine Area, Zhengzhou. The study utilizes the Lasso and Ranger algorithms were utilized in spectral band analysis. Four primary models employed during this process include Artificial Neural Network (ANN), Support Vector Machine, Random Forest (RF), and Partial Least Squares Regression (PLSR). The ideal model was chosen. The results showed that, in contrast to when band collection was based on Lasso algorithm modelling, model precision was higher when it was based on the Ranger algorithm. ANN model had an ideal goodness acceptance, and the modelling developed by RF showed the steadiest modelling consequences. Based on the results, a distinct method is proposed in this study for band assortment at the earlier stage of integrated spectral modelling of SOC. The Ranger method can be used to check the spectral particles, and RF or ANN can be chosen to develop the prediction modelling based on different statistics sets, which is appropriate to create the prediction modelling of SOC content in Dengcao Coal Mine Area. This research avails a position for the integrated spectral of Analysis for Advanced Modelling of Soil Organic Carbon Content in Coal Sources alongside a theoretical foundation for innovating portable device for the integrated spectral assessment of SOC content in coal mining habitats. This study might be significant for the changing modelling and monitoring of SOC in mining and environmental areas.
Do Persons with Disabilities Really Participate in Community Development Services in Ghana? Evidence from the Adenta Municipality

Published: June 2024

This study examined the views of Persons With Disabilities (PWDs) with respect to their participation in community development services in Ghana from the perspective of the Adenta Municipality, Greater Accra Region. The study was a mixed method involving 50 PWDs. Researcher-administered survey and focus group discussion methods were used for data collection. Frequencies, percentages and content analysis were used for analysing the data obtained. The study found that though various community development projects had been undertaken in the Municipality most of these projects were not PWD-friendly. It was discovered that the participation of PWDs in planning, implementing, and evaluating development projects in the Municipality was low. Again, the study found that a one-way directional form of communication characterized community development services in the Municipality. Besides, communication challenges faced by PWDs in community development include inadequate information, poor consultation, and poor engagement. Moreover, existing communication strategies used by development actors particularly do not promote the active participation of PWDs in community development. This has resulted in a feeling of exclusion among PWDs in the design, planning and execution of community development initiatives. The study highlights the need for better communication strategies in community development practice that are inclusive of PWDs. The study offered a number of policy recommendations including the need for development actors in the Municipality to devise measures to identify PWDs groups, send them messages about development issues, involve them in community development decisions at all stages, and adopt more proactive and innovative measures to improve communication in community development practice.

To study the chemical evolution across cosmic epochs, we investigate Ne, S, Cl, and Ar abundance patterns in the Cosmic Origins Spectrograph Legacy Archive Spectroscopic SurveY (CLASSY). CLASSY comprises local star-forming galaxies (SFGs; 0.02 < z < 0.18) with enhanced star formation rates, making them strong analogues to high-z SFGs. With direct measurements of electron temperature, we derive accurate ionic abundances for all elements and assess ionization correction factors (ICFs) to account for unseen ions and derive total abundances. We find Ne/O, S/O, Cl/O, and Ar/O exhibit constant trends with gas-phase metallicity for 12+log(O/H) < 8.5 but significant correlation for Ne/O and Ar/O with metallicity for 12+log(O/H) > 8.5, likely due to ICFs. Thus, the applicability of the ICFs to integrated spectra of galaxies could bias results, underestimating true abundance ratios. Using CLASSY as a local reference, we assess the evolution of Ne/O, S/O, and Ar/O in galaxies at z > 3, finding no cosmic evolution of Ne/O, while the lack of direct abundance determinations for S/O and Ar/O can bias the interpretation of the evolution of these elements. We determine the fundamental metallicity relationship (FMR) for CLASSY and compare to the high-redshift FMR, finding no evolution. Finally, we perform the first mass–neon relationship analysis across cosmic epochs, finding a slight evolution to high Ne at later epochs. The robust abundance patterns of CLASSY galaxies and their broad range of physical properties provide essential benchmarks for interpreting the chemical enrichment of the early galaxies observed with the JWST.
Phase-dependent Spectral Shape Changes in the Ultraluminous X-Ray Pulsar NGC 5907 ULX1
Authors: Miura Daiki , Kobayashi Shogo B. , Yamaguchi Hiroya
Published: June 2024

The discovery of coherent pulsations from several ultraluminous X-ray pulsars (ULXPs) has provided direct evidence of a supercritical accretion flow. However, the geometrical structure of such an accretion flow onto the central neutron star remains poorly understood. NGC 5907 ULX1 is one of the most luminous ULXPs, with a luminosity exceeding 1041 erg s−1. Here we present a broadband X-ray study of this ULXP using the data from simultaneous observations with XMM-Newton and NuSTAR conducted in 2014 July. The phase-resolved spectra are well reproduced by a model consisting of a multicolor disk blackbody emission with a temperature gradient of p = 0.5 (T ∝ r
−p
) and a power law with an exponential cutoff. The disk component is phase-invariant and has an innermost temperature of ∼ 0.3 keV. Its normalization suggests a relatively low inclination angle of the disk, in contrast to the previous claims in other literature. The power-law component, attributed to the emission from the accretion flow inside the magnetosphere of the neutron star, indicates phase-dependent spectral shape changes; the spectrum is slightly harder in the pre-peak phase than in the post-peak phase. This implies that the magnetosphere has an asymmetric geometry around the magnetic axis and that hotter regions close to the magnetic pole become visible before the pulse peak.
The Distance to the S147 Supernova Remnant
Authors: Kochanek C. S. , Raymond John C. , Caldwell Nelson
Published: June 2024

In the absence of a parallax distance to a pulsar or a surviving binary in a supernova remnant (SNR), distances to Galactic SNRs are generally very uncertain. However, by combining Gaia data with wide-field, multifiber echelle spectroscopy, it is now possible to obtain accurate distances to many SNRs with limited extinction by searching for the appearance of high-velocity Ca ii or Na i absorption lines in hot stars as a function of distance. We demonstrate this for the SNR S147 using the spectra of 259 luminous blue stars. We obtain a median distance of 1.37 kpc (1.30–1.47 kpc at 90% confidence), which is consistent with the median parallax distance to the pulsar of 1.46 kpc (1.12–2.10 kpc at 90% confidence) but with significantly smaller uncertainties. Our distance is also consistent with the distance to the candidate unbound binary companion in this SNR, HD 37424 at a photogeometric distance of 1.45 kpc (1.40–1.50 kpc at 1σ). The presence of high-velocity absorption lines is correlated with the Hα/O [iii] emission-line flux of the SNR but not with the radio flux.
Changing Look of the Optical Spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
Authors: Paiano Simona , Falomo Renato , Treves Aldo , Scarpa Riccardo , Sbarufatti Boris
Published: June 2024

Following the high activity of the γ-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we obtained optical spectroscopy with the Gran Telescopio Canarias of the counterpart. We detect a clear emission line at 3830 Å identified as Lyα that confirms the redshift of source at z = 2.153. Comparing with previous spectroscopy, we find an increase of the continuum by a factor ∼10, and a significant decrease of the C iv 1550 emission line flux by a factor ∼5. This produces a dramatic drop of the equivalent width from ∼20 to 0.8 Å, which is suggestive of a very high jet activity. The full width half maximum of the emission lines are midway (1000–2000 km s −1) between those typical of the broad and narrow regions of quasars. Based on this, the source classification is intermediate between flat spectrum radio quasar and BL Lac object.

Published: June 2024

Over the last decade, access to global data has become increasingly critical for research, allowing insights into diverse biological, environmental, and societal questions at a macro scale. Digitization has greatly enhanced the use of herbarium data in the analysis of species distribution data and ecological niche modeling. Yet, sources on modeling and mapping methodology using open source software is greatly lacking for beginners. We have created a replicable and thorough tutorial to visualize species occurrence data and exploratory analysis that was developed by undergraduates with broad backgrounds and levels of expereince. This tutorial integrates the open-source programs QGIS, MaxEnt, and R to develop distribution maps, using bryophytes as a case study, to promote the accessibility of open source software and remote access learning. This tutorial has already set the foundation for further research into distribution modeling of rare Illinois bryophytes to better understand the potential impact of climate change.

Authors: Sukhorukov Alexander , Kushunina Maria , Stepanova Nina , Kalmykova Olga , Golovanov Yaroslav , Sennikov Alexander
Published: June 2024

Orenburg Region is located in the South Urals, mostly in the steppe zone and is characterised by various landscapes suitable for many Chenopodiaceae. The species of Chenopodiaceae are present in all major plant communities (saline vegetation, steppes, on limestone, chalk and sand, and as degraded or ruderal communities). In the steppe zone, many native subshrubby species (Atriplex cana, Caroxylon laricinum, Suaeda physophora) playing a crucial role in semi-deserts (known as southern steppes in the recent Russian literature) located southwards of Orenburg Region are locally found, and several annuals (Salicornia perennans, Suaeda spp.) are most common dominants in plant communities. Some typical semi-desert species (Kalidium foliatum, Bassia hyssopifolia, Soda foliosa, Spirobassia hirsuta) are found in the easternmost part of the region.

We compiled a checklist of Chenopodiaceae in Orenburg Region, with two new records (Chenopodium virgatum, Corispermum laxiflorum), based on our critical revision, comprehensive inventory of herbarium specimens and documented observations and field research. In total, we report 76 species in the Region, which is the third-highest number of the Chenopodiaceae species compared with other administrative territories of European Russia, North Caucasus and West Siberia. Alien and native taxa are distinguished. Zonal patterns of species distributions are confirmed. A preliminary conservation status is proposed for each native species. Three species are recommended for exclusion from the Red Data Book of Orenburg Region: Petrosimonia triandra (because of its extensive distribution), Kalidium foliatum and Anabasis salsa (because of the lack of actual threat to their populations). Arthrophytum lehmannianum and Salsola rosacea are considered threatened (Vulnerable) because of their restricted occurrence and population size and because their localities are under anthropogenic pressure. Atriplex hortensis, Atriplex rosea, Chenopodium acuminatum, C. karoi, C. praetericola, C. vulvaria, Climacoptera affinis, C. crassa, Halimocnemis karelinii, Salsola paulsenii and Xylosalsola arbuscula are excluded from the checklist, based on various reasons as discussed in the paper. Point distribution maps are provided for each species. Agriophyllum pungens (Vahl) Link is accepted as the correct authorship instead of "M.Bieb. ex C.A.Mey."

Published: June 2024

Based on a critical examination of type specimens, images of living plants, and the literature has shown Rhododendron oligocarpum to be conspecific with R. leishanicum. Although slight variations in corolla colour exist amongst different populations of R. oligocarpum, it does not serve as a key distinguishing trait. Therefore, we reduced R. oligocarpum to a synonym of R. leishanicum, and recommend placing it in Subsection Maculifera.

Étude pilote : « Exploration des liens entre stimulation sensorielle et développement des capacités de communication chez l’enfant avec tsa sévère »
Authors: Devilliers Hélène , Tabone Michael
Published: June 2024

Les enfants avec un tsa ont souvent des particularités dans le traitement des informations sensorielles. Nous faisons l’hypothèse que la mise en place d’une méthode de stimulation sensorielle basée sur les intérêts sensoriels de l’enfant favorise l’émergence de capacités de communication préverbales et verbales et permet de diminuer par ailleurs les besoins de stimulations chez les enfants présentant un tsa modéré à sévère. Nous avons donc élaboré un protocole de recherche-action pour quelques enfants dans le but d’observer si la communication s’améliorait avec des séances de psychothérapie à visée d’intégration sensorielle. Les bénéfices de cette recherche-action se situent sur le plan institutionnel, dans l’investissement de l’équipe et bien évidemment dans le soin apporté auprès des enfants tsa . Nous avons observé les bénéfices dans les prérequis relationnels permettant une communication avec un autre différencié.

L’autisme est une gageure pour le monde scientifique qui par ses efforts répétés cherche à le définir pour mieux le servir. Pour les parents qui supportent cet état au travers de leur enfant porteur du handicap, l’autisme est une blessure autant douloureuse que monstrueuse. L’idée de faire se rencontrer le monde de la recherche et le réel des familles en Côte d’Ivoire tend à conjuguer les effets et les efforts pour une meilleure compréhension du phénomène autisme. La mise en place d’une guidance psychoéducative parentale aspire à faire un micro-bilan de l’état actuel des actions parentales à l’endroit de leur enfant atteint d’autisme et de leur proposer un accompagnement pluridimensionnel pour améliorer leur compréhension du handicap, le fonctionnement individuel et singulier de leur enfant autiste et réviser pour un confort conjoint (parents, fratrie et enfant) leurs pratiques éducatives. L’objectif majeur est un mieux vivre l’autisme dans son énigme de vérité, mieux vivre et faire vivre l’enfant autiste dans sa particularité développementale et sa personnalité et déployer dans les familles des compétences psychoéducatives optimales pour la satisfaction de tous. Les auteurs proposent ici une réflexion sur cette thématique à partir de la mise en œuvre d’un dispositif d’accompagnement des familles à Abidjan et Yamoussoukro appelé projet « Répit ».

Published: June 2024

Au Vietnam, l’autisme n’est plus un concept nouveau. L’autisme a été reconnu comme un handicap nécessitant un accompagnement depuis 2019. Cette aide auprès des enfants est par nature une collaboration entre de nombreux professionnels issus de nombreux domaines différents. Cependant, il n’y a pas de coordination entre les spécialistes et le nombre de personnes ayant une formation approfondie dans chaque domaine est très faible.

The competence of digital entrepreneurship in education: Analysis of the perception of university students
Authors: Sánchez Vera María del Mar , López Vicent Patricia
Published: June 2024

Purpose: From an educational perspective, digital entrepreneurship comprises the convergence of the dimensions of entrepreneurship competence and digital competence. The EmDigital project has generated a model of digital entrepreneurship based on the proposals of Entrecomp and Digcom models that, from a transversal approach, addresses digital entrepreneurship from the perspective of challenges and the development of new opportunities that technology can offer.Design/methodology/approach: The project conducted a study using a non-experimental and exploratory design with the objective of analyzing the digital entrepreneurship competence of 135 final-year students from the Polytechnic University of Cartagena. A questionnaire validated by experts and exploratory factor analysis was used to assess the four dimensions of digital entrepreneurship competence: identification of opportunities, action planning, implementation and collaboration, and management and security.Findings:The results show that the students feel they are more competent in the dimension of management and security, while they perceive that the dimension related to the identification of opportunities in the framework of digital entrepreneurship is less developed. It is concluded that it is necessary to establish a series of common and interdisciplinary indicators around digital entrepreneurship that can be reinforced in all degrees, so students could develop good strategies related to digital entrepreneurship regardless of the degree they come from.Originality/value: The added value of this study lies in its comprehensive approach, the solid theoretical foundation on which it is based, its exploratory approach, the integration of key dimensions, the identification of specific areas of improvement and the practical recommendations to address these deficiencies in higher education. -------This research has been carried out within the framework of the project “EmDigital. kills for digital entrepreneurship of university students” (https://www.um.es/emdigital/), which is funded by the SénecavFoundation (Agency Science and Technology Agency of the Region of Murcia, Spain). It has also been funded by the project MAEDU (Framework for Analysing Digital Entrepreneurship in Universities), project funded by the Ministry of Science and Innovation of the Government of Spain. Proyecto PID2022-139332NB-I00 financiado por MICIU/AEI /10.13039/501100011033/ y por FEDER, UE. The data has been collected thanks to the participation of undergraduate students from Polytechnic University of Cartagena (Spain).
Riemannian gradient descent for spherical area-preserving mappings
Authors: Sutti Marco , Yueh Mei-Heng
Published: June 2024

We propose a new Riemannian gradient descent method for computing spherical area-preserving mappings of topological spheres using a Riemannian retraction-based framework with theoretically guaranteed convergence. The objective function is based on the stretch energy functional, and the minimization is constrained on a power manifold of unit spheres embedded in three-dimensional Euclidean space. Numerical experiments on several mesh models demonstrate the accuracy and stability of the proposed framework. Comparisons with three existing state-of-the-art methods for computing area-preserving mappings demonstrate that our algorithm is both competitive and more efficient. Finally, we present a concrete application to the problem of landmark-aligned surface registration of two brain models.

Published: June 2024

A conical disc arranged in different stacks parallel, or series works as a compression spring used in different machine applications. This work focusing on presenting a comparison between theoretical calculation with experimental performance of single spring and their stacked. This comparison with cold stamping manufactured based on spring force and spring rate constant related with deflection. The spring design is chosen according to Belleville spring standard depending on sheet thickness of the selected material Carbon steel C55S-1/1204. Results experimental force for a single spring started high to about (0.2 mm) deflection, then reduced less than theoretical results, with a deviation (32.5 %). The parallel stacked of springs show, the force increased with increasing numbers of discs in spring stack, without clearly affecting deflection of stack in theoretical, but the experimental have (13.5%) variation for two springs and (14.6%) for three discs. While, the series stacked, show the spring deflection increased with increasing numbers of springs in the stack, without clearly affecting the spring force, with a variation of (38.5%) for two spring and (10%) for three discs. Finally, the spring rate increased with increasing deflection till reaching flatness, where the theoretical calculations show higher than the measured experimentally in about (31.5%).
Numerical Analysis of Thermally Developing and Fully Developed Flow in Different Configurations of Microchannels
Authors: Kahdem Ghufran , AL-Saadi Ahmed
Published: June 2024

Microchannels based on Micro Electromechanical Systems (MEMS) have garnered a great lot of interest over the past 40 years from the fields of microfluidics and biomedicine. In order to address the problem of heat dissipation in incredibly small integrated circuits with up to 790 W/cm2 of huge heat dissipation capabilities, Tuckerman et al. [1] first proposed the microchannel heat rejection idea in 1981. These channels are typically at the microscale, with characteristic dimensions on the order of micrometers 10-6m or smaller as shown in Figure 1 [2]. These channels often exist at the microscale and have characteristic diameters of micrometres 10-6m or less. Microchannels display distinct fluidic behaviour as a result of their small size. Because the flow is normally laminar and the Reynolds number is low, the flow pattern is predictable. Capillary forces and other surface forces become comparatively more important. As a result, fluid behaviour in microchannels is greatly influenced by surface wetting characteristics and channel surface roughness.
