introduction: the survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. implant success also is affected by the maintenance of the crestal bone around implants. the aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...
Introduction: The concept quality cost for all clinical laboratories perform routine and specialized tests of any size and scope has many applications. Familiarity of managers and employees of clinical laboratories with quality cost concept prevent wasted resources and offers laboratory services with high quality to physicians, patients, and other internal and external customers with reasonable...
PURPOSE Copious studies exist regarding the use of stents in pediatric pyeloplasty. Most surgeons use either no stent, an internal (Double-J®) stent or an external transanastomotic pyeloureteral stent. We propose the first known study to compare all 3 methods using a decision tree model that incorporates success rates, complications, patient discomfort and costs. MATERIALS AND METHODS We crea...
هدف این مطالعه بررسی تاثیر دو جنبه کیفیت حسابرسی داخلی یعنی صلاحیت و همکاری حسابرس داخلی در حسابرسی صورتهای مالی است. مطابق تئوری جانشینی حسابرس مستقل با اتکا به نتایج کار حسابرس داخلی در تلاش های خود صرفه جویی می کند که این امر بر حق الزحمه حسابرس مستقل تاثیر خواهد گذاشت. دو ویژگی کیفی حسابرسی داخلی (صلاحیت و همکاری) منجر به حمایت از دیدگاه جانشینی برای توضیح رابطه بین کیفیت حسابرسی داخلی و حق...
Abstract: Military command and control (C2) systems are increasingly challenged by a host of modern problems, namely, internal vulnerabilities and external threats. Several approaches have been suggested in the literature to measure availability and integrity in C2 systems. Despite the importance of developing and maintaining self-protecting and self-healing processes, the simultaneous consider...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
sulfuric acid production plants are one of the main sources of sulfur oxides, emission to the atmosphere. in the present study to control sulfur oxides of sulfuric acid plant two methods have been selected. the first method is desulfurization by ammoniac (plant a) and the second one is a combination of the first method and dry scrubbing process with calcium hydroxide as the absorbent material) ...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
The utilization of unbounded external reinforcing bars is one of the strengthening methods used after loading stage and before failure. The method has been used in different forms to strengthen members of reinforced concrete structures. To investigate the effect of utilization of post-tensioned reinforcing bars in this method of strengthening, a number of reinforced concrete beams was tested. S...
