Abstract
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

Abstract
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.

Abstract
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
Authors: Luty Przemysław A. , Prończuk Mateusz R. , Bizon Katarzyna D. 
Published: December 2024

Abstract
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.

Published: December 2024

Abstract
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

Abstract
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.

Published: December 2024

The Infinity Sculpture by Dunadi is a media representation of the idea of the eternal function of bicycles over time. The infinity statue is primarily made of ferrous metal, so it has the potential for damage in the form of patina and rust, especially when exposed to direct sunlight, rainwater, oxygen, and other substances that accelerate corrosion growth. The current condition of the infinity statue by Dunadi could be better because most of the paint has peeled off, and rust has grown on the entire surface of the metal that is not covered with paint. This article discusses the application of modern metal conservation methods to Dunadi’s Infinity Sculpture. This study’s contemporary metal conservation method compares several synthetic chemicals to clean rust on metal and then apply it to Dunadi’s Infinity Statue. The synthetic chemicals used are some of the rust-cleaning agents available. Synthetic chemicals are available because they are easy to obtain and relatively safe. We tested Several brands of rust cleaners available on the market on metal objects similar to the material for making infinity statues. As a result, the most effective rust- cleaning chemicals contain hydrochloric acid. Patung Infinity karya Dunadi merupakan representasi media dari gagasan tentang fungsi abadi sepeda dari waktu ke waktu. Patung infinity utamanya terbuat dari logam besi, sehingga berpotensi mengalami kerusakan berupa patina dan karat, terutama jika terkena sinar matahari langsung, air hujan, oksigen, dan zat lain yang mempercepat pertumbuhan korosi. Kondisi patung infinity karya Dunadi saat ini bisa lebih baik karena sebagian besar catnya sudah terkelupas, dan karat sudah tumbuh di seluruh permukaan logam yang tidak dilapisi cat. Artikel ini membahas penerapan metode konservasi logam modern pada Patung Infinity karya Dunadi. Metode konservasi logam kontemporer dalam penelitian ini membandingkan beberapa bahan kimia sintetis untuk membersihkan karat pada logam lalu mengaplikasikannya pada Patung Infinity karya Dunadi. Bahan kimia sintetis yang digunakan merupakan beberapa bahan pembersih karat yang tersedia. Bahan kimia sintetis tersedia karena mudah diperoleh dan relatif aman. Kami menguji beberapa merek pembersih karat yang tersedia di pasaran pada benda logam yang mirip dengan bahan untuk membuat patung infinity. Hasilnya, bahan kimia pembersih karat yang paling efektif mengandung asam klorida.

Authors: Sais Vira Cendana , Sari Meiriani , Halim Hendy , Alfara Lady Dhita 
Published: December 2024

ABSTRACT
Background: Dengue prevalence is still high worldwide, as well as in Indonesia. Jakarta is the second province with the most dengue cases in early 2024. Funding and cost constraints hinder dengue diagnosis. This study aims to determine the demographics of dengue cases and predictive factors of severe dengue without diagnostic laboratory examination.
Patients and Methods: This was a retrospective observational study of pediatric patients at Sumber Waras Hospital Jakarta from January-June 2024. Inclusion criteria were probable dengue respondents without dengue diagnostic examination. Data in the form of home address and various predictors of severe dengue were then analyzed univariate and multivariate (chi-square, Fisher exact test, and binary logistic regression), with p value <0.05 considered significant.
Results: There were 162 cases, with 115 dengue cases with warning signs and 47 severe dengue cases; there were 2 deaths in severe dengue. Grogol Petamburan district, especially Grogol urban village, is the area with the highest proportion. Predictors of severe dengue in univariate analysis were age, lethargy, persistent vomiting, abdominal pain, mucosal bleeding, hepatomegaly, clinical fluid accumulation, hematocrit >40%, platelets count <50,000/mm3 + hematocrit >40%, and platelets count <20,000/mm3. On the other hand, multivariate analysis found lethargy, abdominal pain, mucosal bleeding, hepatomegaly, and hematocrit >40% were predictors of severe dengue (p-value <0.05).
Conclusion: Although with limited laboratory examination,d monitoring of dengue warning signs, periodic platelet and hematocrit examination can be a predictor of severe dengue according to WHO 2009 criteria. Larger-scale studies are needed to confirm the predictive factors of severe dengue.
