Processing of Single Crystal Aluminum Using Compacted Alumina Powder
Authors: Dong Jiaqi 
Published: March 2024

This experiment was designed to produce single crystal aluminum specimens through the understanding of solidification and processing parameter effects. In order to conduct the experiment, specimens were prepared by steel die casting and machining. After aluminum specimens were machined and ground, they were placed in the center of a crucible. Alumina powder was then filled and compacted in the crucible. The crucible was placed in a furnace for the remelting process. Finally, it was placed on a heat sink and was allowed to solidify. The powder compacting methods and remelting temperature were the two most important processing parameters. They were modified to improve the test and create single crystal microstructure. It was found that the compacting methods significantly affected the formation of leak within the crucible. Extremely dense powder results in crack openings; extremely loose powder results in formation of branch-like leakages. Uniformly and gently compacted powder will optimize the result. Remelting temperature affects the amount of thermal expansion. High temperature results in large amount of expansion,and causes cracks in the powder. Low temperature requires much more time and it cannot be guaranteed that the specimen is completely melted. The grain size and microstructure of each trial was compared and analyzed. Necessary modification of procedure was also made to improve future results. Finally in the report, the processing parameters and the resulting microstructure were correlated and discussed.

It is known that America is a superpower that has played an important role in global trade, especially after the second world war. While China is emerging as a new force in the increasingly dominant global economy. The purpose of study is to identify global economic competition that occurs between China and the United States. This research uses qualitative methods because it is felt to be more flexible and in-depth in exploring data and using scientific journals, books, etc. as the main reference source. From this study, it was found that the rapid development by China was influenced by the Belt and Road Initiative (BRI) Strategy to bring China, which was originally a donor recipient country, to become the largest donor country to rival the United States. With the implementation of an open economy, China has managed to beat America in GDP PPP growth, where China is at 5.01%, higher than America which is only 2.09%. In addition, the open-door policy makes China the largest manufacturing country in the world and an additional East Asian economic power besides Japan.

Published: March 2024

La production porcine est responsable d’environ 10 % des émissions de gaz à effet de serre (GES) de l’élevage mondial et doit réduire ses impacts. Ces émissions de GES, comptabilisées en sortie de ferme, sont liées à la production d’aliment et la gestion des effluents, pour 60 % et 30 % respectivement. La réduction du taux de protéines alimentaires peut agir sur ces deux sources. Cette revue synthétise les connaissances actuelles sur les bénéfices de cette stratégie pour réduire l’impact changement climatique (CC) en relation avec les matières premières utilisées et la réduction des émissions azotées. Une analyse de cycle de vie (ACV) à l’échelle de l’aliment montre que le CC est réduit de 8 % par point de réduction du taux protéique, grâce au remplacement des matières premières plus impactantes (produits du soja). Ces bénéfices sont dépendants des matières premières disponibles et utilisées, du choix des bases de données d’évaluation environnementale et du contexte technico-économique. La modélisation des émissions azotées en fonction des performances, mise à jour par méta-analyse, permet d’effectuer une ACV en sortie de ferme. Une réduction du CC par kg de porc de 10 % pour un point de baisse du taux protéique est atteignable. Cependant, des lacunes méthodologiques et de connaissances subsistent pour correctement évaluer cette stratégie : facteurs d’émission du N2O, prise en compte de l’utilisation des effluents pour la fertilisation, effet sur les performances zootechniques. Par ailleurs, des évolutions structurelles sont nécessaires pour faciliter la mise en pratique, comme la rémunération des externalités positives.

Authors: Hull Jonathan , Balsamo Luke 
Published: March 2024

Case:
A 50-year-old woman presented to our emergency department with severe intractable atraumatic right hip pain. She was admitted to the hospital, and an orthopaedic consult was requested. She does have a known history of right hip osteoarthritis, but does not actively follow with an orthopaedic surgeon. Advanced imaging was obtained followed by computed tomography–guided biopsy of the right hip to include cartilage and bone. The cultures were negative for growth. An incision and debridement were performed, and necrotic bone was found. Subsequently, an antibiotic spacer was placed secondary to osteomyelitis. Blood cultures and tissue polymerase chain reaction 16S ribosomal RNA were positive for Haemophilus haemolyticus.

Discussion:
Culture-negative osteomyelitis remains a treatment challenge. Several organisms have the potential to cause osteomyelitis. Unfortunately, a high percentage of patients have fallen into the category of culture-negative disease. This is a case report discussing an immunocompetent patient with a rarely reported cause of osteomyelitis and how to assist with definitive diagnosis of culture-negative cases.

Published: March 2024

Artikel ini membahas tentang implementasi PSAK 109 pada lembaga ZIS di Indonesia. Zakat merupakan salah satu ibadah penting dalam Islam, dan dapat menjadi pilar utama dalam menegakkan keadilan pada kehidupan bermasyarakat serta meningkatkan kesejahteraan umat. Jika dilihat secara demografis mayoritas penduduk Indonesia adalah beragama Islam, hal tersebut menjadikan potensi penghimpunan dana zakat juga akan besar. Secara realita menunjukkan bahwa potensi zakat yang besar dapat diterapkan sesuai harapan terlebih dengan adanya PSAK 109 yang membantu mempermudah dalam pencatatan dana zakat, infak, dan sedekah. Adanya PSAK 109 diharapkan pencatatan dan pelaporan zakat oleh Lembaga ZIS Indonesia akan menjadi seragam (uniformity) dan dapat dibandingkan (comparability). PSAK No. 109 ini diterbitkan oleh Ikatan Akuntan Indonesia (IAI) pada tahun 2010 dengan tujuan untuk mengatur tentang pengakuan, pengukuran, penyajian dan pengungkapan transaksi zakat dan infak/sedekah yang berlaku bagi lembaga Zakat, Infak, dan Sedekah yang bertugas untuk menghimpun serta menyalurkan zakat dan infak/sedekah. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana implementasi PSAK 109 pada lembaga ZIS di Indonesia dan hambatan apa yang timbul dalam implementasi PSAK 109 pada lembaga ZIS di Indonesia. Penelitian ini menggunakan pendeketan kualitatif dengan menggunakan jenis penelitian studi pustaka (library research). Hasilnya, ada lembaga ZIS yang sudah menerapkan PSAK 109, ada yang telah menerapkan PSAK 109 namun belum sepenuhnya, ada lembaga yang belum menerapkan PSAK 109. Hambatan yang terjadi karena kurangnya sumber daya manusia yang mumpuni di bidangnya dan sedikitnya pemasukan dari muzakki.

Abstract
Computerized cognitive training (cCT) is recommended as standard therapy for patients with mild cognitive impairment (MCI). While traditional cognitive training involves long waiting times, mobile cCT can efficiently improve the healthcare situation. This interim analysis of the ongoing NeuroNation MED Effectiveness Study (NeNaE) aims to assess first effects of a mobile, gamified cCT (NeuroNation MED) in participants with MCI. In the intention-to-treat analysis, the intervention group (IG) performed 12 weeks of training with the NeuroNation MED app, while the control group (CG) represented a waiting group. This interim analysis included 50 participants (IG: n = 36; CG: n = 14). As primary outcome, we examined the index score of the Neuropsychological Assessment Battery Screening Module (S-NAB). Alpha spending results in an alpha level of .00305 for the interim analysis. This analysis showed first positive evidence for the effectiveness of the intervention where the IG improved significantly in the S-NAB index score (t(35) = 3.17, p = 0.0028, Cohen's d = 0.53). However, ANCOVA revealed no significant group differences between IG and CG in the S-NAB index score (F(1, 47) = 5.39, p = 0.025, ηp2 = 0.125). Additionally, the IG showed a significant mean decrease in subjective memory measured with the CFQ-D (MD = - 10.56, SD = 18.82, t(35)= 3.21, p = 0.0029, Cohen's d = 0.53). Conducting the complete study is crucial to determine the effectiveness of NeuroNation MED.

A comprehensive analysis of aerosol-induced radiative forcing and regional warming patterns in West Africa
Authors: Akinyoola Julius A. , Oluleye A. , Gbode Imoleayo E. 
Published: March 2024

Abstract

Atmospheric aerosols can cause significant perturbations to the Earth's radiative budget and induce substantial regional climate change. West Africa has experienced substantial warming in recent decades, but the drivers behind this regional warming trend remain uncertain. This study conducts a comprehensive analysis to quantify the aerosol radiative forcings and explore the associated regional warming patterns across West Africa. It further unveils a novel method for assessing aerosol radiative forcing, which takes into account Aerosol Instantaneous Radiative Forcing (Aerosol IRF) and its effects on regional energy balance at the top of the atmosphere and at the earth’s surface. Ten-year Copernicus Atmosphere Monitoring Service (CAMS) reanalysis datasets spanning 2009–2018 were integrated to characterize the spatiotemporal distributions of Aerosol IRF and the impacts on regional climate change. Aerosol-Cloud Interaction at the Top of the Atmosphere shows varying radiative forcings across seasons and regions, ranging from 1.5W/m2 in the Sahel and Sahara Desert to 2.5W/m2 in the Guinea coast during DJF and MAM, suggesting a significant regional warming effect, particularly in the Sahel and Sahara. A reduction value of 1.0 W/m2 during the JJA seasonal period was also observed and this is predominant over Aerosol IRFari of Aerosol-Radiation Interaction. The Longwave spectrum of aerosol IRFari of Aerosol-Radiation Interaction at the surface reveals positive values mostly evident in the Sahel and Sahara Desert regions of West Africa with a minimum value of 0.2W/m2 and maximum value of 0.4W/m2 in some specific locations like Nigeria, Niger, and Chad Republic during DJF and MAM seasonal period indicating warming effects. During JJA, a reduction of -0.5W/m2 suggests cooling effects, predominantly observed over Aerosol-Cloud Interaction at the Surface. A positive correlation between Aerosol IRF and absorption of solar radiation by clouds and atmosphere influences radiative balance at the top of the atmosphere. The low RMSE (0.02) indicates a good fit between Aerosol-Cloud and Aerosol-Radiation Interaction. Conversely, a negative correlation (-0.04) between surface Aerosol IRF and longwave radiation suggests that absorbed shortwave radiation influences emitted longwave radiation. It was also discovered that IRFari of Aerosol-Radiation Interaction can boost regional forcing, which in turn causes warming and probably sets off extreme events in the area. That aerosol IRFaci seasonal variability can be reinforced by IRFari. In West Africa, regional aerosol effects must be taken into account when developing climate policies and initiatives. Reducing anthropogenic aerosol emissions can both ameliorate air pollution improve air quality and also mitigate regional climate impacts.
Heterologous Expressions of foxtail millet (Seteria italica) mitogen-activated protein kinase kinase (SiMKK) group A genes regulate root development under salt stress in Arabidopsis thaliana

Abstract

The MAPK cascade is evolutionarily conserved in eukaryotes and involved in the regulation of plant growth, development, resistance to biotic and abiotic stress. However, the gene function of MAPK cascade in foxtail millet (Seteria italica) is rarely studied. In this study, RNA sequencing was performed and MAPK cascade was the main enrichment pathway in foxtail millet after salt treatment. Meanwhile, fourteen genes encoded and mitogen-activated protein kinase kinases (SiMKKs) were identified which could be divided into 4 subfamilies. Under salt treatment, the expression levels of 11 SiMKKs were upregulated and the expression level of SiMKK6-2 in group A had the biggest increase. SiMKK1 and SiMKK6-1, which were the other two member of in the same subfamily, also significantly upregulated under salt stress. Overexpression of these three genes in Arabidopsis thaliana reduced the sensitivity of roots to salt stress. Transgenic plants had more lateral roots. The decrease of primary root length of transgenic plants under salt stress was significantly lower than that of wild type plants. These three genes are involved in regulating the development of primary and lateral roots of plants, which can maintain better root development to improve plant tolerance to salt stress.

Abstract

Background
Trials investigating the effect of mesenchymal stem cells (MSCs) on heart failure (HF) have been controversial. This study was conducted to investigate whether the transplantation of MSCs after HF could help improve clinical outcomes and myocardial performance indices.
Methods
Using a systematic approach, electronic databases were searched for randomized controlled trials (RCTs), which evaluated the transplantation of MSCs after HF. The outcomes of interest included clinical outcomes and myocardial function indices. We also assessed the role of age, cause of heart failure, cell origin, cell number, type of donor (autologous/allogeneic), and route of cell delivery on these outcomes. Using the random-effects method, a relative risk (RR) or mean difference (MD) and their corresponding 95% confidence intervals (CI) were pooled.
Results
Seventeen RCTs including 1684 patients (927 and 757 patients in the intervention and control arms, respectively) were enrolled. The RR (95% CI) of mortality was 0.78 (0.62; 0.99, p = 0.04) in the MSC group compared to the controls. HF rehospitalization decreased in MSC group (RR = 0.85 (0.71 to 1.01), p = 0.06), but this was only significant in those who received autologous MSCs (RR = 0.67 (0.49; 0.90), p = 0.008). LVEF was significantly increased among those who received MSC (MD = 3.38 (1.89; 4.87), p < 0.001). LVESV (MD= -9.14 (-13.25; -5.03), p < 0.001), LVEDV (MD= -8.34 (-13.41; -3.27), p < 0.001), and scar size (standardized MD= -0.32 (-0.60; -0.05), p = 0.02) were significantly decreased. NYHA class (MD= -0.19 (-0.34; -0.06), p = 0.006), BNP level (standardized MD= -0.28 (-0.50; -0.06), p = 0.01), and MLHFQ (MD= -11.55 (-16.77; -6.33), p = 0.005) significantly decreased and 6-minute walk test significantly improved (MD = 36.86 (11.22; 62.50), p = 0.001) in the MSC group. Trials were not affected by the participants’ etiology of heart failure, while trials with the autologous source of cells, MSC doses lower than 100 million cells, and intracoronary injection performed significantly better in some of the outcomes.
Conclusion
Transplantation of MSCs for ischemic or dilated heart failure patients may reduce all-cause mortality and improve clinical condition. Moreover, this treatment would improve left ventricular function indices and reduce scar size.

Abstract

Accurate prediction of the longevity of Ldam, as temporary or permanent hydraulic structures, is crucial for ensuring downstream safety of lives and properties. This study proposes an intelligent forecasting model to accurately predict the longevity of Ldam. Firstly, a database containing a large amount of Ldam data is collected and organized, with key factors selected as indicators for the prediction system. Statistical indicators of the database are calculated, and in-depth analysis is conducted using correlation heatmaps and violin plots. Secondly, an intelligent forecasting model is constructed based on an improved intelligent optimization algorithm and ensemble learning. The model consists of multiple base learners (MLP, SVR, CatBoost) and a meta-learner (LightGBM). To effectively improve model performance, an improved intelligent optimization algorithm called IGTO is proposed to optimize the hyperparameters of the meta-learner within the stacked ensemble learning framework. In the analysis of the model's prediction results, prediction plots and regression plots are provided, and a series of evaluation metrics (R2, Adj-R2, RMSE, MAE, MAPE, VAF) are calculated. The results demonstrate that the IGTO stacked model exhibits high accuracy and reliability in predicting the longevity of Ldam, with computed values of R2 = 0.98, Adj-R2 = 0.98, RMSE = 93.98, MAE = 48.59, MAPE = 0.46, VAF = 98.29, showing good agreement with actual observed values. Furthermore, the model outperforms other prediction models and previous empirical formulas, validating the effectiveness and practicality of the IGTO improved optimization algorithm and ensemble learning framework. Additionally, the SHAP method is employed to assess the importance and impact of each input parameter on the model's predictions, quantifying the significance of each influencing factor on Ldam longevity and providing reference for engineering professionals. Moreover, collaborations were conducted with technical personnel from a local enterprise in Yangquan City, Shanxi Province, where on-site investigations were carried out and first-hand data of 46 sets of Ldam were obtained using drone-based 3D laser scanning technology. These data further enhance the value of this study, enrich the currently scarce database of Ldam, and further validate the generalization ability of the model and its effectiveness in future practical engineering applications. In conclusion, this study enriches the currently scarce database of Ldam and provides an effective method for accurate longevity prediction, demonstrating significant practical significance.
