OBJECTIVE One or two burr-hole craniostomies with subgaleal or subdural drainage system and irrigation are the most common methods for surgical treatment of CSDH. The aim of this study is to compare the advantages or disadvantages of these techniques used for CSDH. METHODS Seventy patients were treated by burr-hole subdural drainage or subgaleal drainage system with irrigation. Our patients w...

In this paper, a three-parameter bounded unit distribution with flexible hazard rate called the generalized log Burr XII (UGLBXII) is derived. To show importance of proposed distribution, we establish some its mathematical properties such as random number generator, ordinary moments, TL conditional reliability and uncertainty measures. We characterize UGLBXII via innovative technique...

A new distribution called the Lindley-Burr XII (LBXII) is proposed and studied. Some structural properties of including moments, conditional order statistics R´enyi entropy are derived. Maximum likelihood estimation technique used to estimate model parameters. simulation study examine bias mean square error maximum estimators presented applications real data sets in illustrate usefuln...

We introduce a flexible lifetime distribution called Burr III-Inverse Weibull (BIII-IW). The new proposed has well-known sub-models. BIII-IW density function includes exponential, left-skewed, right-skewed and symmetrical shapes. model's failure rate can be monotone non-monotone depending on the parameter values. To show importance of distribution, we establish various mathematical properties s...

In this paper, Burr-type XII ̄X synthetic schemes are proposed as an alternative to the classical ̄X synthetic schemes when the assumption of normality fails to hold. First, the basic design of the Burr-type XII ̄X synthetic scheme is developed and its performance investigated using exact formulae. Secondly, the non-side-sensitive and side-sensitive Burr-type XII ̄X synthetic schemes are int...
