        Integration of remote sensing and geophysical data for structural lineaments analysis in the Rag-e-Sefid oil/gas field and surrounding areas, SW Iran

        Zahra Tajmir Riahi,Khalil Sarkarinejad,Ali Faghih,Bahman Soleimany,Gholam Reza Payrovian 한국지질과학협의회 2023 Geosciences Journal Vol.27 No.3

        The major faults in the Rag-e-Sefid oil/gas field and surrounding areas are detected by integrating digital satellite, aeromagnetic, and seismic data to improve resolution and reduce ambiguity. The main structural lineaments are extracted through the processing of satellite images. The continuity of the lineaments onto the magnetic basement is analyzed by processing the aeromagnetic data, which reveals the distribution of the basement faults, their relationship with each other, and their segmentation or continuation in the magnetic basement. The seismic profiles across the major faults support resolving the predominant geological structures of the region and identifying the sense of movement on the fault surfaces. In addition, fieldwork was performed to verify the detections and characterize the status and mechanism of the identified faults. The results indicate that the main detected faults in the area are classified into seven major categories: the Nourooz-Hendijan-Izeh, NW and SE Rag-e-Sefid, Zagros Frontal, Kharg-Mish, Izeh, and Mountain Front faults. The Rag-e-Sefid and the Nourooz-Hendijan-Izeh Faults have been considered critical structural lineaments in creating the final geometry of the Rag-e-Sefid anticline and have controlled the fracture characteristics in the Asmari reservoir.

        Diabesity Associates with Poor COVID-19 Outcomes among Hospitalized Patients

        Zeinab Nikniaz,Mohammad Hossein Somi,Masood Faghih Dinevari,Ali Taghizadieh,Leila Mokhtari 대한비만학회 2021 The Korean journal of obesity Vol.30 No.2

        Background: Although numerous studies have investigated obesity’s negative effect on coronavirus disease 2019 (COVID-19) outcomes, only a limited number focused on this association in diabetic patients. In this study, we analyzed the association between obesity and COVID-19 outcome (death, intensive care unit [ICU] admission, mechanical ventilation needs, quick Sequential Organ Failure Assessment [qSOFA] score, and confusion, urea, respiratory rate, blood pressure [CURB-65] scores) for hospitalized diabetic patients. Methods: In this prospective hospital-based registry of patients with COVID-19 in East Azerbaijan, Iran, 368 consecutive diabetic patients with COVID-19 were followed from admission until discharge or death. Self-reported weight and height were used to calculate body mass index (kg/m2) upon admission. Our primary endpoint was analyzing obesity and COVID-19 mortality association. Assessing the associations among obesity and disease severity, ICU admission, and mechanical ventilation was our secondary endpoint. Results: We analyzed data from 317 patients and found no significant difference between obese and non-obese patients regarding frequency of death, invasive mechanical ventilation, ICU admission, CURB-65, or qSOFA scores (P>0.05). After adjusting for confounding factors, obese diabetic COVID-19 patients were 2.72 times more likely to die than non-obese patients. Moreover, ventilator dependence (adjusted odds ratio [aOR], 1.87; 95% confidence interval [CI], 1.03–4.76) and ICU admission (aOR, 2.41; 95% CI, 1.11–5.68) odds were significantly higher for obese patients than non-obese patients. Conclusion: The results of the present study indicated that obesity worsens health outcomes for diabetic COVID-19 patients.
