Purpose. The surgical expertise to perform robotic partial nephrectomy is heavily dependent on technology. The Da Vinci Xi (XI) is the latest robotic surgical platform with significant advancements compared to its predecessor. We describe our operative technique and experience with the XI system for robotic partial nephrectomy (RPN). Materials and Methods. Patients with clinical T1 renal masses...

BACKGROUND Renal papillary necrosis (RPN) is associated with a number of comorbid conditions. However, it has been rarely reported in patients with fungal infections of the kidney. METHODS We analyzed medical records of our hospital for the last two decades and identified 29 patients with fungal infections and RPN. RESULTS Among the 29 patients, there were 24 men and 5 women. The median (ra...

El Fallah and Haddad 1] have described how distributed planning can be modeled using Recursive Petri Nets (RPN). This paper shows how an RPN model can be implemented using RTNet, an environment that supports distributed real-time interaction among computational agents with arbitrarily complex transition actions. The underlying RTNet implementation and interaction language are based on the schem...

OBJECTIVE Administering medication to hospitalised infants and children is a complex process at high risk of error. Failure mode and effect analysis (FMEA) is a proactive tool used to analyse risks, identify failures before they happen and prioritise remedial measures. To examine the hazards associated with the process of drug delivery to children, we performed a proactive risk-assessment analy...

Hydraulic systems are widely used in the aeronautic, machinery, and energy industries. The functions that these perform require high reliability, which can be achieved by examining causes of possible defects failures taking appropriate preventative measures. One most popular methods to achieve this goal is FMEA (Failure Modes Effects Analysis), foundations were developed implemented early 1950s...

This improves, in these cases, by 1 dimension upon the result of Milgram [8], who proved, by constructing bilinear maps, that if n ≡ 7 mod 8, then RPn can be immersed in R2n−α(n)−4 , where α(n) denotes the number of 1s in the binary expansion of n. In [2, Theorem 1.2], the first and fourth authors used obstruction theory to prove that if n ≡ 7 mod 8, then RPn can be immersed in R2n−D , where D ...

introduction gotvand-olia as one of the largest constructional projects in iran has been constructed on the karoun river, between masjed soleiman and gotvand regulatory dam in khuzestan province. it is situated in 382.8 km away from the river estuary at a distance of 25 km north of shoushtar city. this study was conducted to identify and assess the risk of gotvand-olia dam on the environment at...

A dam construction project is exposed to various risks due the amount of investment, duration implementation, complexity design and etc., these will lead human financial losses. Thus, based on three principles, including (i) time, (ii) quality, (iii) cost, identifying, assessing, ranking risks, Occupational Safety Health (OSH) can have a significant impact objectives. The machinery maintenance ...
