Introduction: Worldwide specific diseases are jeopardizing people’s health in the world as well as in Iran. Chronic renal failure as a developed and irreversible failure is usually progressive. End Stage Renal Disease (ESRD) is a situation when renal function is not sufficient to preserve one’s life leading to acute uremia resulting in dialysis and/or kidney transplantation for the patients. Although dialysis methods bring about complications for the patients, peritoneal dialysis is relatively cost-effective and more convenient to survive. The present study aimed to investigate (the) Etiologic factor of renal failure and imposed complications of peritoneal dialysis in the patients of Isfahan Alzahra hospital. Materials and Methods: It was a cross-sectional descriptive study conducted on 67 patients in Isfahan Peritoneal Dialysis Center. The data from the patients were collected through a two-section questionnaire whose first section was allocated to demographic information and the second part was related to the disease and complications of peritoneal dialysis. The collected data were analyzed by SPSS version 18. Results: The findings showed that there were 39 (58%) males and 28 (42%) females. Mean age of the subjects was 48 (18.8) years old. Regarding marital status, 65% were married and 35% were single. Considering complications, 28 subjects (53.5%) had infectious complications while 24 subjects (46.2%) had non-infectious complications. The highest frequency in etiologic factor of renal failure was diabetes mellitus in 29 subjects (43.9%) and the lowest for polycystic kidney in 2 subjects (3%);in addition, hypertension was observed in 51 subjects (77.3%). Discussion: The most frequent and important complication of peritoneal dialysis catheters is infection, which may result in catheter loss and discontinuation of peritoneal dialysis (PD). Diabetes and hypertension were found as the most important etiologic factors for renal failure. They should also be considered a

在本文研究中,通过利用优势边缘缺口盘型(END)试样,确定了石灰石的断裂韧性,提出了一种新的石灰石归一化相应力、高相变的计算方法.采用柔性有限元法(FEM)对试样的I型(张开)-断裂韧性进行了精确计算,并得到了相应实用公式.在试验中,还使用含缺口巴西圆盘(NBD)试件,测试了END程序的准确性.为了在数值上重现这些测试并验证断裂韧性测量的正确性,还对END测试进行了离散元分析.数值模拟结果与实验结果吻合良好.然而,END研究所确定的韧性水平低于NBD测试规定的韧性水平,这是因为END石灰石样品中的缺口具有均匀的拉伸应力分布.
