One of the main components of pavement management system (PMS) is pavement evaluation. Several indices have been defined for the evaluation of existing pavement. The Pavement Condition Index (PCI) is a common index used for pavement evaluation. In order to calculate PCI, a significant volume of condition data -based on distress surveying- is required. The objective of this research is to reduce...
در مقالۀ حاضر شاخص ترکیبی بهبودیافتۀ خشکسالی (OSDI)، برای پایش زمان واقعی این پدیده در مناطقی با پوشش اراضی ناهمگن پیشنهاد میشود. بارش بهعنوان یکی از عوامل مهم خشکسالی، توسط اندازهگیری ایستگاههای زمینی و بهکمک دادههای برآورد بارش TRMM در این مطالعه وارد شد. سپس، هریک از سه شاخص نرمالشدۀ رطوبت، شامل شاخصهای تفاضل نرمالشدۀ پوششگیاهی (NDVI)، مرئیـ طول موج کوتاه مادون قرمز خشکسالی (VS...
The importance of cardiac biomarkers in the prognosis of patients with acute coronary syndrome is clear. However, there are some controversies regarding measuring these cardiac biomarkers post angioplasty through percutaneous coronary intervention (PCI). In this study we will review the importance of increased cardiac biomarkers after elective PCI on the prognosis of patients. Also, the definit...
coronary artery disease is one of the most common causes of mortality and morbidity across the world. its treatment includes medical treatment, coronary artery bypass graft (cabg) and percutaneous coronary intervention (pci). the purpose of this study was to investigate the effect of pci on echocardiographic findings of left ventricular (lv) systolic and diastolic function. 115 patients with co...
Background and Objective: Acute myocardial infarction (MI) is caused due to coronary artery occlusion and divided into two forms of ST-elevation (STEMI) and non-ST-elevation (NSTEMI) myocardial infarction. This study aimed to determine the success rate of treatment with primary PCI (percutaneous coronary intervention) versus thrombolysis in the establishment of perfusion and to evaluate the sho...
The demand for more Peripheral Computer Interconnect (PCI) device configurations beyond the limit set in the PCI local bus specification has prompted the development of several PCI-PCI bridge solutions. This paper describes a new PCI Industrial Computer Manufacturers Group (PICMG) PCI-ISA bus architecture implementation using Digital Equipment Corporation PCI-PCI bridge technology. Layered PCI ...
Background: Frequent Percutaneous Coronary Intervention (PCI) procedures are being performed on a daily basis in Iran. However, no study has been reported on the current PCI practice in patients with acute coronary syndrome (ACS) in Iran. We aimed to describe the clinical characteristics and treatment patterns in Iranian ACS patients treated with PCI. Methods: Between February 2017 and July...
pneumatosis cystoides intestinalis (pci) is a rare condition charachterized by the presence of multiple gases filled cysts in the gastro intestinal tract. in this article we present three cases with different features, who at the end evaluation pci was diagnosed. the first patient present with rectorrhagia (submucosal pci). the second patient present with dyspepsia (subserosal intestinal pci) a...
در این مقاله تصادفات استان بوشهر مورد تجزیه و تحلیل قرار گرفته اند. برای این منظور، به سهم هر یک از عوامل موثر در وقوع تصادفات استان اعم از انسان، وسیله نقلیه و جاده اشاره گردیده است. سپس با استفاده از مطالعات میدانی، 21 قطعة یک کیلومتری از جاده های مختلف استان مورد ارزیابی قرار گرفته اند و بر روی آنها آزمایش تعیین ضریب اصطکاک (به روش آونگ انگلیسی) و محاسبه خرابی روسازه راه (به روش PCI) انجام ش...
Objectives: This study aimed to investigate the efficacy of calcitriol on Ischemia-reperfusion Injury (IRI) and inflammatory biomarkers in patients with non-ST-segment elevation acute coronary syndromes (NSTEACS) undergoing elective Percutaneous Coronary Intervention (PCI). Methods: A total of 72 patients with NSTEACS were randomly divided into two groups: (1) the calcitriol-treated grou...
