We evaluated the intrinsic quality of eight routine test systems for the measurement of serum total potassium (K+), as well as the routine quality of four of these systems, using a group of 60 single-donation serum samples that had been certified with an ion chromatography reference method. The intrinsic quality of the tests was evaluated by analysis of the sera in the manufacturers' applicatio...

Triazolam caused no significant increase in the total error at 0.05 and 0.1 mg/kg. However, at 0.2 mg/kg, it caused a significant increase in total error. Almost the same findings were observed with brotizolam and rilmazafone. That is, at 0.2 and 0.5 mg/kg of brotizolam, 0.5 and 1.0 mg/kg of rilmazafone caused no significant increase in the total error. However, brotizolam at 1.0 mg/kg and rilm...

Horizontal directional drilling (HDD) is widely used in soil and rock engineering. In a variety of conditions, it is necessary to estimate the torque required for performing the reaming operation. Nevertheless, there is not presently a convenient method to accomplish this task. In this paper, to overcome this difficulty based on the basic concepts of rock engineering systems (RES), a model for ...

We present an adaptive finite element method (AFEM) of any polynomial degree for the Laplace-Beltrami operator on C graphs Γ in R (d ≥ 2). We first derive residual-type a posteriori error estimates that account for the interaction of both the energy error in H(Γ) and the surface error in W 1 ∞(Γ) due to approximation of Γ. We devise a marking strategy to reduce the total error estimator, namely...

a total of 260709 monthly test day milk records of 30903 first lactation holstein cows was used to determine the best function to describe the lactation curve. the records were obtained from first lactation holstein of 216 herds from 1988 to 2006 in khorasan province. the functions used in current study were wood’s incomplete gamma function, ali and schaeffer function, and legendre function of ...

Background/Aim: Intraoperative changes in patient position or other that would disrupt the decisive during preoperative preparation directly have a negative impact on acetabular cup orientation patients undergoing total hip arthroplasty. This study aimed to compare standard support system and novel lateral (Maltepe), which ensures stable decubitus positioning perioperative period, arthroplasty ...
