PENGARUH TEMPERATUR DAN KOMPOSISI Nb TERHADAP INTERDIFUSI PADUAN U-Zr-Nb. Telah dilakukan simulasi percobaan intermik bahan bakar U-Zr-Nb dengan pelat aluminium. Mula-mula dibuat ingot paduan U-6Zr-2Nb, U-6Zr-5Nb, dan U-6Zr-8Nb menggunakan tungku peleburan busur listrik. Ingot yang diperoleh dipotong-potong menjadi berukuran ketebalan 2-3 mm dan diameter sekitar 5-6 mm selanjutnya ditutup menggunakan pelat Al pada salah satu sisinya serta dipress. Setelah dipress, ingot paduan U-6Zr-2Nb, U-6Zr-5Nb, dan U-6Zr-8Nb dipanaskan pada temperature 350 dan 450 °C selama 1 jam. Setelah dipanaskan ingot dikenai beberapa pengujian yaitu mikrostruktur menggunakan mikroskop optik dan Scanning Electron Microscope (SEM) yang dilengkapi dengan Energy Dispersive Spectrometer (EDS), kekerasan menggunakan uji kekerasan mikro, dan fasa dengan alat X-ray diffractometer (XRD). Hasil pemeriksaan mikrostruktur menunjukkan masih terlihat dengan jelas batas antara lapisan (interface) U-6Zr-2Nb, U-6Zr-5Nb, dan U-6Zr-8Nb dengan lapisan Al. Semakin tinggi kandungan Nb semakin rapat rapat interface antara kedua lapisan. Pada pengujian kekerasan mikro terlihat bahwa kekerasan pada interface sulit diukur sedangkan pada daerah U-Zr-Nb menunjukkan kenaikan kekerasan pada pemanasan dari 350 menjadi 450 °C, sedangkan pada bagian Al terjadi penurunan kekerasan pada kenaikan temperatur pemanasan dari 350 menjadi 450 °C. Terbentuk senyawa UO3 pada semua sampel uji sedangkan fasa γ-U terbentuk pada sampel U-6Zr-2Nb baik yang dipanaskan pada temperatur 350 maupun 450 °C.Kata kunci: Intermik, paduan U-Zr-Nb, aluminium, mikrostruktur, kekerasan, fasa.

Aim To study the relationship between the type of circulation, severity and localization of atherosclerotic damage of coronary arteries, results of laboratory and instrumental tests, and historical data in patients with multivascular coronary lesions and atrial fibrillation (AF) that developed after coronary bypass surgery.Material and methods This was a novel, retrospective study of data of patients after elective coronary bypass surgery at the Cardiac Surgery Department #1 of the N.V. Sklifosofsky Research Institute of Emergency Care from December, 2018 through December, 2020. The study included 100 patients. The main group consisted of 20 patients whose early postoperative period (first 7 days after surgery) was complicated with postoperative atrial fibrillation (POAF) (mean age, 65.15±9.7 years). The comparison group included 80 patients without the POAF complication during the early postoperative period (mean age, 62.0±9.16 years). Prior to the coronary bypass surgery, all patients underwent clinical, laboratory, and instrumental examination. Based on data of selective coronary angiography, localization, severity of coronary atherosclerotic damage (according to angiographic classification), number of affected arteries, and the type of circulation were taken into account.Results Intergroup differences in the incidence and localization of myocardial infarctions in history, severity of arterial hypertension in history, class of chronic heart failure (according to the New York Heart Association, NYHA, classification), and heart rate were absent. 100 % of patients had left atrial (LA) dilatation not correlated with the development of AF in the early postoperative period. According to data of coronary angiography, there was no statistically significant association between the type of circulation and the development of POAF. The right type of myocardial blood supply prevailed in patients of both groups. There was no correlation between the severity and localization of coronary atherosclerotic lesions and the development of AF in the early postoperative period.Conclusion The development of AF following coronary bypass surgery was not associated with features of coronary atherosclerotic lesions, which may indicate active development of inter- and intra-systemic anastomoses in patients with long-term history of chronic coronary atherosclerosis.

Sternum foramen may be misinterpreted as acquired lesions such as gunshot wound, fracture, lytic lesions, etc. Sternal foramen leaves the lung, heart and large vessels unprotected while performing invasive procedures such as bone marrow aspiration, acupuncture leading to life-threatening complications such as pneumothorax and cardiac tamponade. From a medicolegal perspective, identifying the morphological anomalies or variations of xiphoid process aid in the individualization process by serving as points of similarity when their occurrence has been recorded antemortem. In addition, their antemortem records in the form of previous x rays make important data for skeletonized remains to be identified.The present study was carried using sternal bones removed during autopsy on a total of 350 cases above the age of 30 years and has established aincidence of 6.57% for sternal foramen.Forensic pathologists should be meticulous enough to rule out errors in determining the nature and cause of death in worrying cases as sternal foramen is highly likely to be confused with gun-shot wounds or traumatic antemortem injury.

Abstract
Identifying the spatial characteristics of nitrogen (N) and phosphorus (P) emission from agriculture to water bodies and quantifying effect factors are critical to explore the mitigation options. A high-resolution NUFER (Nutrient Flow in food chains, Environment and Resources) model based on geology, meteorology, land use data, statistical data, and field investigation was used to quantify the spatial characteristics of N/P emissions in Hainan Island, China, driving forces was analyzed and effective measures to reduce emissions in 2035 was explored with scenario analysis. Overall, 98 Gg N from agriculture entered water bodies in 2018, of which the crop system contributed 70%; 15 Gg P entered water bodies, animal system contributed 78%. Nitrate (NO-3) leaching (65%) and direct discharge of animal manure (69%) accounted for the most to the N and P emissions, respectively. 89% of N and 92% of P emissions occurred in plain areas. Spatial overlay analysis showed that high N and P emissions mainly concentrated in the western and northeastern plain areas. At the sub-basin scale, Nandu River was the largest basin of agricultural N/P emissions, accounting for more than 20% of the total emissions. Our correlation analysis showed that N/P emissions were significantly correlated to natural (such as elevation, slope and soil texture) and anthropogenic (e.g., rural income, population density, planting structure and livestock density) factors. We further analyzed the emissions of N/P can be reduced by 71Gg and 14 Gg by 2035 respectively, via reducing food chain waste and consumption, importing more food and improving production efficiency, especially prohibiting the direct discharge of livestock manure. Our research quantified agricultural N and P emissions to the water bodies in a high-resolution context and explored the most effective options for reduction of agricultural non-point source pollution (ANPS) emissions at the island scale.

Abstract
Background
In a flipped classroom (FC) model, blended learning is used to increase student engagement and learning by having students finish their readings at home and work on problem-solving with tutors during class time. Evidence-based medicine (EBM) integrates clinical experience and patient values with the best evidence-based research to inform clinical decisions. To implement a FC and EBM, students require sufficient information acquisition and problem-solving skills. Therefore, a FC is regarded as an excellent teaching model for tutoring EBM skills. However, the effectiveness of a FC for teaching EBM competency has not been rigorously investigated in pre-clinical educational programs. In this study, we used an innovative FC model in a pre-clinical EBM teaching program.
Methods
FC’s teaching was compared with a traditional teaching model by using an assessment framework of prospective propensity score matching, which reduced the potential difference in basic characteristics between the two groups of students on 1:1 ratio. For the outcome assessments of EBM competency, we used an analysis of covariance and multivariate linear regression analysis to investigate comparative effectiveness between the two teaching models. A total of 90 students were prospectively enrolled and assigned to the experimental or control group using 1:1 propensity matching.
Results
Compared with traditional teaching methods, the FC model was associated with better learning outcomes for the EBM competency categories of Ask, Acquire, Appraise, and Apply for both written and oral tests at the end of the course (all p-values<0.001). In particular, the “appraise” skill for the written test (6.87±2.20) vs. (1.47±1.74), p <0.001), and the “apply” skill for the oral test (7.34±0.80 vs. 3.97±1.24, p<0.001) had the biggest difference between the two groups.
Conclusions
After adjusting for a number of potential confunding factors, our study findings support the effectiveness of applying an FC teaching model to cultivate medical students' EBM literacy.

Published: January 2022

Abstract
This paper presents a solution for the security of low detail images in real-time applications over open or unsecured networks. The diffusion and confusion operations are both performed based on Henon and Baker chaotic map. The XOR and permutation operations are used to obtain diffusion and confusion in the algorithm. In the proposed technique, the high detail image is used as a key. The computer simulation results and security analysis are given to ensure the validity and strength of the proposed technique. In the security analysis, we have analyzed key space analysis, cropping attack analysis, noise attack analysis, and differential attack analysis. Some statistical analyses like entropy, histogram, and correlation coefficients are also given to check the strength of the presented technique.
