Given that a unit is of age ‘t’ the remaining life after time t is random. It is well known that the class of distribution with decreasing mean residual life (DMR), contains the class of distribution with increasing hazard rate. If exponential length-biased approximations, bounds and stability results on the distance between residual life reliability functions, with monotone weight functions an...

Three-dimensional counter-diffractometer data and a full-matrix least-squares method have been used to refine the crystal structure of a sub-silicic hastingsite in the space group C2/rn. The chemical composition of the amphibole is Na~.95K~.a~Cax.~4(Mg1.17Fe~+7Mn~.~4Ti~.39Fe~9A~.5~)Si5.2~A~2.~3~22.5~(~H)x.a4 with ceil parameters a = 9"8659(4), b = I8"OI39(8), c = 5'3545(2)-&, and fi = IO5O82(1)...

In this study, the growth parameters of big-scale sand smelt (Atherina boyeri Risso, 1810) in İznik Lake has been determined with traditional (length weight relationships (LWRs), von Bertalanffy (VB), condition factor (CF)) and modern approaches (Artificial Neural Networks - ANNs). A total 635 specimens (44.84% female 55.16% male) were collected from local fisherman during hunting season betwee...

OBJECTIVE The intensive care unit is synonymous of high severity, and its mortality rates are between 5.4 and 33%. With the development of new technologies, a patient can be maintained for long time in the unit, causing high costs, psychological and moral for all involved. This study aimed to evaluate the risk factors for mortality and prolonged length of stay in an adult intensive care unit. ...

forty sheep skins were allocated into two groups. group one was sheared using shearing machine and group two was chemically dewooled using 15 percent sodium sulfide. results indicated that fibre diameter of slipewool (39.3 ± 2.3 µm) was significantly (p< 0.05) higher than the sheared wool fibers (36.3 ± 0.7 µm), but staple length of slipewool (3.3 ± 0.7 cm) was significantly (p< 0.05) lower tha...

OBJECTIVE In clinical intensive care practice, weaning from mechanical ventilation is accompanied by concurrent early patient mobilization. The aim of this study was to compare the success of extubation performed with patients seated in an armchair compared to extubation with patients in a supine position. METHODS A retrospective study, observational and non-randomized was conducted in a mixe...

Let x(t) be a trajectory of the gradient of a real analytic function and suppose that x0 is a limit point of x(t). We prove the gradient conjecture of R. Thom which states that the secants of x(t) at x0 have a limit. Actually we show a stronger statement: the radial projection of x(t) from x0 onto the unit sphere has finite length.

A frequent and well-founded criticism of the maximum a posteriori (MAP) and minimum mean squared error (MMSE) estimates of a continuous parameter γ taking values in a differentiable manifold Γ is that they are not invariant to arbitrary ‘reparametrizations’ of Γ. This paper clarifies the issues surrounding this problem, by pointing out the difference between coordinate invariance, which is a si...
