Kontekstualisasi QS Al-Isrā (17): 31 tentang Larangan Pembunuhan Anak Pendekatan Tafsir Kontekstual Abdullah Saeed
Authors: Putri Zahfa Lisnaeni , Naqiyah Naqiyah
Published: December 2024

Idealnya anak merupakan anugrah yang diamanahkan Allah kepada hamba-Nya sehingga harus dilindungi dan dipenuhi hak-haknya. Akan tetapi, akhir-akhir ini tidak sedikit terjadi pembunuhan dan kekerasan terhadap anak dalam aneka ragam bentuknya. Pembunuhan terhadap anak sudah terjadi pada zaman Jahiliyah, sebagaimana  telah direspon Al-Qur’an dalam surah Al-Isrā (17): 31. Disebutkan bahwa masyarakat Jahiliyah membunuh anak-anak perempuan mereka karena takut akan terjadinya kemiskinan, namun tidak sedikit orang tua di zaman sekarang membunuh anaknya dengan berbagai macam sebab yakni bukan hanya takut miskin. Oleh karena itu, kami tertarik untuk mengkaji lebih dalam mengenai QS Al-Isrā (17): 31. Tujuan penelitian ini adalah untuk mengetahui relevansi QS Al-Isrā (17): 31  tentang larangan membunuh anak karena takut miskin, dengan menggunakan teori kontekstual Abdullah Saeed. Hasil penelitian ini adalah: QS Al-Isrā (17): 31  mengandung larangan membunuh (dalam bentuk instruktif dan universal). Jika dikontekstualisasikan, larangan tersebut dapat diperluas jenisnya pada aneka ragam kekerasan fisik, psikis, seksual, dan ekonomi. Demikian juga penyebabnya bukan hanya karena faktor ekonomi, tetapi dapat mencakup faktor lainnya seperti masalah keluarga, sosial, dan politik. Penelitian ini merupakan kajian kualitatif dengan jenis kepustakaan (library search) dengan sumber primer QS Al-Isrā (17): 31  dan sumber sekunder berupa kamus Al-Qur’an, kitab-kitab tafsir, artikel dalam jurnal, dan literatur lain yang relevan.
Kajian Al-Qur’an Di Tengah Disrupsi Digital: Pengemasan Ulang Materi Ulumul Qur’an Di Perguruan Tinggi Keagamaan Islam Indonesia
Authors: Mutaqin Enjen Zaenal
Published: December 2024

Artikel ini bertujuan untuk menggali apa yang harus dilakukan oleh para cendekiawan Muslim di Indonesia, mulai dari mana, kemasan kajian Al-Quran seperti apa yang harus disesuaikan dengan tantangan zaman saat ini. Artikel ini mengulas karya-karya ilmiah mengenai temuan-temuan terbaru terkait tantangan akibat disrupsi digital sebagai landasan argumentasinya. Kemudian dilanjutkan dengan menganalisis sumber‘ulūm al-qur’ān dengan menggunakan metode intertekstualitas dan beberapa saran lebih lanjut. Penelitian terkini terkait kajian Al-Qur'an harus melakukan transformasi diri. Ada tiga langkah simultan yang perlu dilakukan: digitalisasi teks sumber kajian Al-Qur'an, pengumpulan seluruh penelitian terkini terkait Ulumul Quran, dan pendalaman filsafat ilmu di bidang Ulumul Qur'an. Ketiga upaya tersebut memerlukan masukan dari tiga pihak: lembaga yang mempunyai kewenangan untuk menciptakan lingkungan akademik yang mendukung, tradisi penelitian dan kegiatan ilmiah yang koheren, dan jumlah ilmuwan Al-Quran yang terlibat aktif sebagai aktor dan agen perubahan yang lebih baik. Ketiga komponen tersebut tumbuh dan berkembang secara bersamaan dalam sejarah peradaban keilmuan Islam. Tanpa ketiga komponen tersebut berkembang secara bersamaan, peradaban ilmu pengetahuan Islam tidak akan mencapai potensi maksimalnya.

Reinterpretasi Makna Jihad Dalam Alquran Perspektif Jasser Auda
Authors: Afifah Malihatul , Wahab M. Royyan Nafis Fathul
Published: December 2024

Penelitian ini bertujuan untuk melakukan reinterpretasi terhadap makna jihad dalam Alquran yang telah dilakukan pada penelitian sebelumnya dengan menggunakan paradigma Jasser Auda. Jihad diinterpretasikan sebagai upaya bersungguh-sungguh berjuang dan berkorban di jalan Allah yang salah satunya ialah melakukan perang fisik. Padahal, jihad dengan perang fisik hanya ditemukan di dalam surat al-Taubah di mana surat tersebut memang berada pada konteks peristiwa peperangan antara umat Muslim melawan kaum musyrik. Artikel ini merupakan penelitian kualitatif-deskriptif dengan pendekatan kajian literatur. Artikel ini memakai teknik searching dan filtering pada aplikasi Publish or Perish dengan menggunakan opsi title words “Jihad dalam Alquran”, “Jihad dalam Al Qur’an”, dan “Jihad dalam Al-Quran” dari tahun 2017 – 2022 dalam mengumpulkan data pada database Google Scholar. Temuan dalam penelitian ini ialah memunculkan reinterpretasi makna jihad dalam Alquran yang didasarkan pada maqasid shari’ah Jasser Auda antara lain: Berjuang dan bersungguh-sungguh untuk menjaga perdamaian atas nama Agama (ḥifẓ al-din), Mendidik keluarga agar memiliki akhlak dan martabat yang islami serta melindungi keluarga dari ancaman luar yang berpotensi destruktif (ḥifẓ al-nasl), Berjuang dan bersungguh-sungguh dalam menuntut ilmu pengetahuan sehingga dapat memunculkan temuan-temuan baru yang memberikan kemashlahatan bagi umat manusia (ḥifẓ al-‘aql), Melindungi seluruh hak asasi manusia demi memberikan keadilan sebagaimana yang telah tertulis di dalam Alquran (ḥifẓ al-‘irdh/ḥifẓ al-nafs), dan Mengorbankan sebagian harta untuk pembangunan manusia dan pengembangan ekonomi sehingga dapat memberikan kesejahteraan secara merata (ḥifẓ al-mal).
Dilemmatics of Contemporary Maudhu’i Commentaries in The Middle East
Authors: Basri Ahmad Faizal , Hermansah
Published: December 2024

Dilematika al-Tafsir al-Mawdu’i dari berbagai pendapat menyebabkan diskursus tersebut menjadi enggan untuk diterima atau sebaliknya. Tentu tidak terlepas dari subjektif masing-masing tokoh yang notabenenya kontemporer. Pada kesempatan ini, peneliti berupaya flashback terhadap pemahaman al-Tafsir al-Mawdu’i, agar jelas batasan-batasan istilah dan aplikasinya dari masing-masing tokoh. Jadi tidak menyisahkan masalah pada skop istilah umumnya. Pendekatan library research dengan analisis induktif-komparatif adalah metode yang dipakai oleh peneliti pada paper ini. Adapun hasil penelitian ini mengungkapkan, ada empat macam yang ditawarkan mereka, yaitu al-Mawdu’i fi al-Qur’an, al-Mawdu’i fi al-Surah al-Qur’aniyyah, al-Mustalah al-Qur’ani dan tatabu’ al-‘Alaqat. Adapun macam pertama para tokoh kontemporer saling bersepakat menerimanya, sedangkan yang kedua dan ketiga ditolak dan ditentang oleh ‘Abd al-Sattar dan al-Farmawi, kecuali Baqir al-Sadar memilih setuju asalkan dengan istilah al-Wahdah al-Mawdu’iyyah li al-Surah al-Qur’aniyyah. Adapun tokoh yang mendukung penuh terhadap kedua macam tersebut adalah Mustafa Muslim. Kemudian macam ketiga adalah al-Mustalah al-Qur’ani yang dipelopori oleh al-Khalidi dan keempat adalah tatabu’ al-‘Alaqat, atau disebut al-Munasabat yang dipelopori oleh Abd al-Hamid Ghanim. Kedua macam yang terakhir ini sangatlah tidak pas apabila disandingkan dengan al-Mawdu’i al-Qur’ani.
Naskah Jalalain Museum Masjid Agung Demak dan Museum Masjid Agung Jawa Tengah: Analisis Komparatif Kodikologis
Authors: Anasom  , Fais Nor Lutfi
Published: December 2024

Artikel ini mengkaji dua naskah tafsir Jalalain yang tersimpan di Museum Masjid Agung Jawa Tengah dan Museum Masjid Agung Demak. Temuan terhadap dua naskah ini diperoleh ketika dilakukan upaya digitalisasi terhadap seluruh naskah kuno koleksi dua museum tersebut. Kajian dalam artikel ini dimaksudkan untuk melakukan perbandingan terhadap aspek kodikologis naskah. Sebagaimana tujuan kajian yang hendak dicapai, kajian dilakukan dengan menggunakan analisis kodikologis yang menjadi bagian dari disiplin ilmu filologi. Di samping itu, kajian juga dilakukan dengan menggunakan analisis parateks yang menyasar pada seluruh aspek naskah termasuk informasi yang didapat dari luar fisik naskah. Tahapan kajian dimulai dari melakukan deskripsi terhadap naskah untuk kemudian melakukan analisis sesuai dengan piranti analisis yang ada. Hasil dari kajian mendapati bahwa dua naskah tersebut berasal tradisi yang hampir sama. Hal ini didapatkan dari karakteristik penggunaan naskah dalam dunia pengkajian, yakni pada pola dan metode pemaknaan, pemberian catatan tambahan, dan fungsi naskah sebagai media menuliskan informasi penting di luar topik naskah. Namun demikian, kepastian masa disalinnya naskah membutuhkan kajian lain yang lebih mendalam dengan melakukan analisis bahasa yang digunakan dalam pemaknaan dalam naskah.

Authors: Dahlan Ahmad , Voak Adam , Chin James , Mariyani-Squire Edward , Aprianto Naerul Edwin Kiky
Published: December 2024

Studies on Indonesia's political conditions during the New Order until the 1990s reveal a significant shift in political dynamics, transitioning from a stance largely closed to Islamic interests to one that increasingly accommodated Islam through specific policies. This article aims to determine the influence of the ethnopolitical dynamics of Islam formed by the New Order on the development of Islamic banking law and its impact on the financial sector in Indonesia. Through a historical and contextual literature review, supplemented by interviews, it was observed that ethnopolitical dynamics significantly influenced the evolution of Indonesian banking law during and after that period. The influence of Islamic ethnopolitics, particularly in academic circles, has increasingly emerged as a dynamic force in facilitating the development of Islamic banking in Indonesia, underscoring the numerous challenges encountered in achieving market acceptance. Although its growth has not met market expectations, ethnopolitically, Islam continues to lobby for Islamic banking regulations. Furthermore, since 2019, the role of ethnopolitics has continued to realize policy and regulatory responses aimed at encouraging the growth of Islamic finance in Indonesia.

Lip balm lidah buaya formula II dengan rasio cocoa butter dan minyak jarak 11:43,2 merupakan formula terbaik yang stabil pada keseluruhan parameter.
 

Lip balm is an essential lip care product due to its function in maintaining moisture and providing protection against dryness. A combination of cocoa butter and castor oil is commonly used in lip balm formulations due to its moisturizing properties; however, an incorrect ratio can affect the product stability and texture. Aloe vera (Aloe vera Linn.) extract provides additional benefits in terms of hydration and soothing, thereby enhancing the efficacy. This study aims to evaluate the conformity of the lip balm with specified standards and to determine the optimal ratio of cocoa butter to castor oil based on its stability. The lip balm was formulated in three different formulations with varying cocoa butter and castor oil ratios: 10:44.2 (formula I), 11:43.2 (formula II), and 12:42.2 (formula III). Storage conditions were set at 40 °C and RH 75% ± 5% for 30 days. All formulations met the pecifications, including organoleptic properties, hardness, specific gravity, melting point, spreadability, and pH. The cocoa butter-to-castor oil ratio influenced the melting point and pH characteristics of the lip balm. Lip balm formula II, with a cocoa butter and castor oil ratio of 11:43.2, was the best formula, stable across all parameters.

Published: December 2024

ABSTRACT
This study aims to explore the role of teachers in instilling moral values in early childhood through the storytelling method, which is regarded as an engaging and effective approach. To achieve this goal, a qualitative descriptive method was employed, utilizing data collection techniques such as observation, interviews, and documentation, providing a comprehensive understanding of the phenomenon under investigation. The research was conducted at TKIT Al-Mumtaz, focusing on teachers in class B2.The findings revealed that during the planning stage, teachers selected teaching modules that incorporated interesting and relevant storytelling methods, with the intention of shaping children's characters in alignment with social norms and religious values. In the implementation phase, the study demonstrated that the effectiveness of these teaching modules significantly increased children's enthusiasm during lessons, enabling them to grasp the commendable morals taught by the last Prophet more easily. Furthermore, in evaluating the role of teachers, the research highlighted that the storytelling method—particularly in sharing captivating stories of the Prophet—was highly effective in enhancing children's morals. Children not only remembered the stories but also applied the lessons in their daily lives. These findings underscore the vital role of teachers in nurturing children to develop good and responsible character traits.

Authors: Sa’u Putra Adhitya Frensly , Jasron Jahirwan Ut , Sanusi Arifin
Published: December 2024

Fossil fuels such as coal still dominate as fuel for power plants worldwide. Using fossil fuels in most power plants can increase greenhouse gas (GHG) emissions, which affect climate change. Biomass is a renewable energy source expected to reduce greenhouse gas emissions. The use of biomass energy sources as a mixture of fossil fuels, known as co-firing in power plants, has been widely done to reduce dependence on fossil fuels. This research will review the influence of biomass mixture on the efficiency of coal power plant boilers. The mixture's composition and the type of biomass used will significantly affect the Boiler's efficiency. The percentage of biomass composition, as well as the proper combustion settings, will be able to produce optimal boiler efficiency. The study in this research is expected to provide an overview of the performance of a power plant that performs co-firing so that in addition to getting the benefits of reducing greenhouse gas emissions, good boiler efficiency is also obtained.
Kajian Numerik Pengaruh Geometri Intake Pompa dan Anti-Vortex Device Terhadap Aliran Pada Intake Pompa
Authors: Sianipar Junifer Hotma Parulian
Published: December 2024

Errors in pump intake design are often caused by incorrect geometry, inadequate immersion, and uneven velocity distribution, which cause vibration, noise, reduced discharge, head, and pump efficiency. This study aims to: 1) study the effect of variable pump bay widths of 3 meters, 4 meters, and 5 meters on fluid flow at the pump intake. 2) Study the effect of variable pump bay widths of 3 meters, 4 meters, and 5 meters with anti-vortex devices on fluid flow at the pump intake. This research method uses computational fluid dynamics (CFD) with a tetrahedral mesh because of the complex shape and geometry of the pump intake. The k-ε realizable turbulence model is used to analyze the flow that produces vortices. The results of the study show that based on the variable pump bay width, the average velocity distribution entering the pump bay is still in accordance with the recommended standard, which is below 0.5 m/s. The pump bay with a width of 3 meters has the highest average velocity compared to other pump bays. Based on the variable pump bay width and the use of anti-vortex devices, it is concluded that the pump intake design with anti-vortex devices has a more uniform flow distribution. However, in a pump bay with a width of 3 meters, even though an anti-vortex device is used, the flow distribution remains non-uniform because the geometric width of 3 meters is not sufficient

Interpretación geométrica de la integral doble en el espacio utilizando GeoGebra
Authors: Ayala Chauvin Marco Antonio , Luna Romero Richard Leonardo
Published: December 2024

Las dificultades cognitivas observadas en los estudiantes, a la hora de abordar los conceptos del Análisis Matemático Multivariado, provienen de la no articulación entre las diferentes representaciones de un mismo objeto matemático, particularmente entre el registro algebraico y su respectiva representación geométrica en las integrales dobles, imponiéndose, consecuentemente, la utilización de técnicas algebraicas sin comprender los conceptos. Con base en la Teoría de los Registros de Representación Semiótica, se propone el uso de una secuencia didáctica utilizando GeoGebra. Para su diseño se eligió una aplicación contextualizada a la ingeniería civil y luego se generó una secuencia de actividades donde se exploró el objeto matemático desde un registro gráfico hasta un registro algebraico, es decir, el estudiante parte de elementos geométricos tridimensionales del registro gráfico de un "sólido" para luego realizar la articulación de representación al registro algebraico de la integral doble para luego resolver la aplicación. Finalmente, la secuencia didáctica fue evaluada afirmativamente en aspectos como la comprensión geométrica del objeto matemático y la pertinencia de las características de la secuencia didáctica.

Metaphysics of Reasons and the Defense of Society
Authors: POGHOSYAN Will
Published: December 2024

The chilef problem of metaphysics of reasons is the theoretical substantiation of the steady existence of the best government and society. Reason (Erӧrterung) contains that which presupposes the formation of a concept given a priori. Montesquieu’s theory of separation of powers inspired the Constitution of the United States. But the American founding fathers decidedly rejected Montesquieu’s experience concerning the separation of powers in England. The article deals with the problem of defending Kant’s opinion that logic had made no important step either forward or backward since Aristotle. The work raises the problem of the excrescences of the scientific empiricism of the Vienna Circle. The research attempts to solve the problem connected with the debate concerning the insights of rationalists as mere tautologies. Concerning the problem of relation between the mathematical and dialectical logic, the present work shows that the first type of logic refers mainly to natural, the second mainly to social science. The article discusses the eternal problem of middle classes clearly raised by Aristotle. This problem is successfully solved in China with the help of the differentiated theory of convergence: capitalism within the framework of socialism for the East, socialism within the framework of capitalism for the West.
Adolescent childbearing by social determinants in sub-Saharan Africa
Authors: Boutayeb Abdesslam
Published: December 2024

Adolescent childbearing is a crucial problem challenging policymakers in sub-Saharan African countries. The objective of this study is to show how teenage pregnancy and motherhood is related to social determinants like place of residence, education level and wealth quintiles, and consequently to suggest pragmatic actions susceptible to control the burden of teenage pregnancy. Disaggregated data were analyzed using data covering the decade 2012–2022 and provided by Demographic Health Surveys. In each country considered, the index of dissimilarity (ID) was computed to illustrate the variation of teenage pregnancy and motherhood according to the level of education, the rural-urban residence and the income quintiles. Recent statistics were also used for a comparison between countries. This study showed that childbearing affected 22.7% of African adolescents (15–19 years). However, the rate of adolescent childbearing varied from 40.4% in Nigeria to 5.2% in Ruanda. Moreover, huge differences were found in each country. Teenage girls living in rural areas, illiterate or with low level of education and suffering from poverty are more likely to be early married and to be exposed to pregnancy. The rate of adolescent childbearing is higher in Sub-Saharan African countries compared with countries from Latin America and World Health Organization Eastern Mediterranean. Most of the 31 countries considered in this study suffer from high rate of adolescent childbearing and large iniquities by place of residence and/or education level and/or wealth quintiles. Consequently, policymakers should adopt urgent and efficient strategies to reduce (and ideally to end) early marriage and teenage pregnancy by developing a policy that targets disadvantaged girls living in remote areas, having low or no decent income and suffering from illiteracy or low level of education.
Automatic Hemangioma Detection Algorithm Using a Cascade of K-Means and Active Contour Model
Authors: Cătălina Neghină , Alina Sultana
Published: December 2024

Although mostly harmless, hemangiomas still need to be monitored and occasionally treated to avoid complications. The method presented for accurately segmenting the hemangioma pixels involves the automatic detection of the number of classes in an initial k-means clustering, followed by binarization, morphological operations and a further adjustment of region of interest using active contours. The method has been tested on a database containing a variety of situations, including multiple hemangioma areas, differently colored and textured skin and intrusive hair. Compared to the results before the addition of active contours, the mean global score shows an improvement of more than 1% (from 96.86% to 97.92%).

Published: December 2024

Anti-IH is a common cold agglutinin that is typically clinically insignificant. We present a case that resulted in hemolysis. A 32-year-old male patient with transfusion-independent beta-thalassemia intermedia presented with symptomatic anemia. His blood sample typed as group B, D+ and demonstrated multiple alloantibodies and cold autoantibodies. He was transfused uneventfully, but re-presented 10 days later with recurrent, worsening anemia. At this time, transfusion of group O, phenotype-matched red blood cells (RBCs) resulted in an acute hemolytic reaction. While anemia was initially attributed to drug-mediated bone marrow toxicit y and subsequently to a delayed hemolytic reaction, further evaluation revealed Mycoplasma pneumoniae infection and a cold agglutinin (anti-IH specificity), indicating a likely autoimmune-mediated anemia due to an infectious etiology. Subsequent transfusion of 2 group B, phenotype-matched RBC units using a blood warmer was uneventful. Anti-IH is only rarely associated with hemolytic transfusion reactions, which may be exacerbated when transfusing group O RBC units to group B patients. M. pneumoniae infection likely led to cold agglutinin–mediated hemolysis of endogenous and transfused RBCs. The patient was successfully managed with intravenous immunoglobulin, steroids, rituximab, erythropoietin, hydroxyurea, and amoxicillin clavulanate/azithromycin. This case illustrates the importance of infectious disease evaluation in patients with unexplained anemia, the potential clinical significance of autoanti-IH, and the value of providing type-specific RBC units in these circumstances.

Distinguishing anti-D, anti- C, and anti-G specificities is particularly essential in antenatal cases to ensure proper patient management. The clinical management as well as Rh immune globulin (RhIG) prophylaxis depend on the accurate identification of these distinct antibodies. D− pregnant women with anti-G, but without anti-D, in their serum need RhIG prophylaxis at 28 weeks of gestation, at delivery if the infant is D+, and when clinically indicated to prevent the formation of anti-D and potential hemolytic disease of the fetus and newborn (HDFN). We present two cases in which determining the antibody specificities determined the course of the patient’s treatment. In one case, a 30-year-old, gravida-1, para-0 woman with blood group A, D− and with no previous RhIG administration had the presence of anti-D, -C, and -G in her plasma. Because she had already been alloimmunized and developed anti-D, RhIG prophylaxis was not necessary. In another case, a 37-year-old, gravida-2, para-1 woman with blood group A, D− and no prior RhIG administration had anti-C and anti-G in her plasma. Because she was not sensitized to D, she needed RhIG prophylaxis. In conclusion, pregnant women can develop anti-C and/or anti-G in the absence of anti-D. Therefore, studies should be conducted to differentiate anti-D, -C, and -G in pregnant women who are presumptively identified as having anti-D and anti-C when their medical history (RhIG prophylactic therapy) suggests that anti-D may not actually be present. In the absence of anti-D, pregnant women should receive prophylaxis with RhIG to prevent alloimmunization to D. For pregnant women who are already sensitized to D, RhIG prophylaxis is not needed.

Variant D antigens can cause variable serologic results when typing with Anti-D reagents. There is limited information regarding the ability of Anti-D reagents to differentiate between D variants defined by RHD genotyping. This study was performed to determine if a panel of 20 U.S. Food and Drug Administration–licensed Anti-D reagents can identify molecularly defined D variants. Red blood cells from 119 donors carrying variant RHD alleles were tested at immediate spin (IS) and/or by the indirect antiglobuin test (IAT) using conventional test tube and/or column agglutination technology. Reaction strength at IS and IAT was reviewed to determine whether a pattern of reactivity could be correlated with a specific D variant. Agglutination results from each sample with each Anti-D reagent were combined to assess overall reactivity. The sample set consisted of 21 D variants, based on prior RHD genotyping. Of these variants, nine categories had three or more samples used for analysis (N = 102); 25 RHD*01W.1, 15 RHD*01W.2, 14 RHD*01W.3, 17 RHD*09.01, 14 RHD*09.03, 4 RHD*01W.4, 23 RHD*07, 4 RHD*10.05, and 6 reference allele RHD*01. As expected, IS showed more negative or weak reactions, and IAT produced more positive reactions with 3+/4+ agglutination strength. RHD*01W.3 samples showed strongest reactivity at IS and IAT. Greatest variation in reactivity was observed with RHD*01W.2, showing weakest overall reactivity at IS. All weak D types had at least one sample that yielded a negative result and one sample with 4+ agglutination at IS. Although there were general patterns of reactivity for each variant tested, no one pattern defined all samples carrying the same RHD allele. This study demonstrated that even with 20 different Anti-D reagents, serologic testing alone is insufficient to define weak or partial D types, characterize the risk for alloanti-D, or determine candidacy for Rh immune globulin. The results illustrate how multiple Anti-D reagents can be used to identify samples that should be reflexed to molecular testing.

Published: December 2024

This study analyzed the curvature and radius of curvature in order to characterize an area affected by anthropogenic coal mining activities. The study took place in an area located in Jiu Valley, Romania. 16 control points were considered (CP1 – CP16), for which the quota values were determined (X,Y,Z system) at the moment of analysis (T1) in relation to a reference moment (T0). The differences in quota were calculated (XYZ) between moments T1 and T0. Curvature (Curv) and radius of curvature (RadC) values were calculated. Strong correlation was recorded between Curv and Z(T1-T0), r = -0.847***, between Curv and Dg (diving the ground), r = 0.847***, and between Curv and Ls (land slope), r = 0.891*** (*** p < 0.001). Weak correlation was recorded between RadC and Y(T1-T0), r = 0.586***. Spline type mathematical models described the variation of curvature, and Radius of curvature in relation to the control points (XYZ values), under conditions for curvature, respectively for radius of curvature. According to the multivariate analysis, the PCA diagram resulted, in which PC1 explained 50.737% of variance, and PC2 explained 49.263% of variance. The cluster analysis generated the dendrogram in which the control point CP16 was positioned separately, and the other control points were grouped in a cluster based on similarity (Coph.corr = 0.998). The ranking of the control points, in relation to the values recorded for the Curv and RadC parameters, was done in the form of Scaling dendrogram.

Lidar data is difficult to access for regular users due to the very large memory volume required and the need to handle it with powerful computers and quite expensive specialized software. The presented web application is offered for free in the LidarTools version and at a low cost in the LidarMap version, which combines shape-type vector data with the Lidar point cloud. The application uses a POTREE structure adapted for rapid visualization functions but enhanced with functions for measuring in the point cloud (distances, areas), visualization functions, profile extraction, statistical functions, semi-automatic vectorization functions of linear objects (power lines), coordinate transformation functions, as well as other functions specific to users of such data. It is also presented here the project for stereo vectoring module in LidarMap application.
Optical shadowgraphy analysis of gas bubble equivalent diameters: Factors influencing measurement accuracy in bubble flows

Published: December 2024

The article explores the impact of various factors on the determination of gas bubble equivalent diameters using optical shadowgraphy. The experimental setup involves a liquid-gas system. The results indicate that the distance between the camera and the bubble rise-up plane has negligible influence on measurement precision as long as the area captured is constant. Increasing the number of analyzed frames significantly reduces uncertainties, while higher image magnification leads to increased uncertainties due to a reduced number of frames and smaller area captured. Image distortion correction minimally affects results and precision. The study concludes that factors such as resolution, frame rate, and elongated flow path captured contribute to more accurate determination of equivalent bubble diameters, essential for the determination of mass and heat transfer coefficients in liquid-gas flows. The results indicate that a sufficiently high number of video frames may be more important than indiscriminately increasing the resolution.

Global overpopulation necessitates increased crop yields, yet available arable land is limited. The study compares and evaluates the performance of three machine learning algorithms—Random Forest (RF), Extra Trees (ET), and Artificial Neural Network (ANN)—in crop yield prediction. Using 28,242 samples with seven features from 101 countries, we evaluated these models based on Mean Absolute Error (MAE), R-squared (R^2), and Mean Squared Error (MSE). The ET regression model demonstrated superior performance, achieving an MAE of 5249.03, the lowest among the models tested. Despite having the highest R^2 value of 0.9873, the ANN exhibited higher MAE and MSE values, indicating less reliability. The RF model showed intermediate results. With a prediction accuracy of 97.5%, the ET model proved to be the most effective for crop yield prediction, achieving the highest accuracy reported to date. Future research should explore more advanced algorithms and larger datasets to validate these findings further.

Published: December 2024

This research seeks to contribute to the literature by classifying the operational risks to which companies are exposed and that have an impact on the results of sustainability through taxonomy. This study begins with a systematic literature review that covers 103 documents to build the theoretical constructs and establish the taxonomy; from this, the relationship among the constructs is established through reasoning based on 100 business cases. The results show a relationship between operational risks and corporate sustainability in aspects that generate this link, such as causes and consequences. From this, it is concluded that operational risks could affect corporate sustainability given that, based on case-based reasoning, we found relationship patterns linked by the economic, social, and environmental consequences and temporary effects on companies. The major contribution of this work lies in the proposed classification of operational risks regarding corporate sustainability and the establishment of their relationship. The findings of this study allow the management to classify the operational risk related to sustainability to carry out comprehensive risk management in companies, looking at the effects that this generates in the long term. The main limitation of this research was that the results of the connections can change depending on the analyzed case. In addition, the CBR case base includes many sectors of the economy, which is why it provides heterogeneous results. It was identified that the relationship can change if a sectoral analysis is performed.
