In this paper, we propose a new three-parameter distribution defined on the positive real line, called gamma power half-logistic distribution. It constitutes an extension of using generated mechanism. The capabilities parent are thus improved in several aspects. particular, hazard rate function now presents increasing failure, decreasing and bathtub shapes, which demanded characteristics contex...

In this paper we propose a new lifetime distribution which can handle bathtub-shaped, unimodal, increasing and decreasing hazard rate functions. The model has three parameters and generalizes the exponential power distribution proposed by Smith & Bain (1975) by inclusion of an additional shape parameter. Maximum likelihood estimation procedure is discussed. A small-scale simulation study examin...

The domestic bathtub is an important site for infant drownings. A total population study of drowning and near-drowning accidents involving Honolulu infants has enabled the risks to be specified with greater detail. A series of seven consecutive bathtub immersion accidents is presented. The "at risk" profile comprises highly mobile families of lower socioeconomic status; usually younger siblings...

the prevalence of chronic kidney disease (ckd), as defined by the nfk-kdoqi (the national kidney foundation kidney disease outcomes quality initiative) guidelines, is a glomerular filtration rate less than 60 ml/min/1.73 m2 or the presence of microalbuminuria. ckd is increasing worldwide, leading to an increased risk of cardiovascular disease. there is general agreement on the importance of an ...

The linear exponential distribution is a generalization of the and Rayleigh distributions. This one best models to fit data with increasing failure rate (IFR). But it does not provide reasonable for modeling decreasing (DFR) bathtub shaped (BTFR). To overcome this drawback, we propose new record-based transmuted generalized (RTGLE) by using technique Balakrishnan He. family RTGLE distributions ...

A new parametric (3-parameter) survival distribution, the lognormal-power function distribution, with flexible behaviour is introduced. Its hazard rate function can be either unimodal, monotonically decreasing or can exhibit a bathtub shape. Special cases include the lognormal distribution and the power function distribution, with finite support. Regions of parameter space where the various for...

BACKGROUND There has been little research on bathroom accidents. It is unknown whether the shower or bathtub are connected with special dangers in different age groups or whether there are specific risk factors for adverse outcomes. METHODS This cross-sectional analysis included all direct admissions to the Emergency Department at the Inselspital Bern, Switzerland from 1 January 2000 to 28 Fe...

Medical treatment of pulmonary Mycobacterium avium complex (MAC) disease does not always provide curative effects and is frequently hampered by recurrence. This suggests the presence of a reservoir for MAC in the environment surrounding patients. We previously reported the recovery of MAC isolates from the residential bathrooms of outpatients. In the present study, to ascertain the colonizing s...

BACKGROUND The diagnostic criteria for bathtub drownings are not standardized, and the risk factors associated with bath-related deaths are unclear. METHODS We analyzed a Korean nationwide database of bath-related deaths that occurred between January 2008 and December 2015. Eighty-four cases were enrolled after reviewing 31,123 autopsy records. RESULTS The subjects' ages ranged from 18 to 9...
