Numerical approximation to a solution of the modified regularized long wave equation using quintic B splines
In this work, a numerical solution of the modified regularized long wave (MRLW)
equation is obtained by the method based on collocation of quintic B-splines over
the finite elements. A linear stability analysis shows that the numerical scheme based
on Von Neumann approximation theory is unconditionally stable. Test problems
including the solitary wave motion, the interaction of two and three solitary waves
and the Maxwellian initial condition are solved to validate the proposed method by
calculating error norms L2 and L∞ that are found to be marginally accurate and
efficient. The three invariants of the motion have been calculated to determine the
conservation properties of the scheme. The obtained results are compared with other
earlier result
Numerical solutions of the MRLW equation by cubic B-spline Galerkin finite element method
In this paper, a numerical solution of the modified regularized long wave (MRLW) equation
has been obtained by a numerical technique based on a lumped Galerkin method using cubic B-spline finite elements. Solitary wave motion, interaction of two and three solitary waves have been studied to validate the proposed method. The three invariants ( 1 2 3 I ,I ,I ) of the motion have been calculated to determine the conservation properties of the scheme. Error norms L2 and L∞ have been used to measure the differences between the exact and numerical solutions. Also, a linear stability analysis of the scheme is proposed
The Acute Effects of Velocity Loss During Half Squat Exercise on Jump Performance
The velocity loss (VL) approach during squat exercise may increase the post-activation potentiation enhancement effect on squat jump performance. If this method succeeds, then different conditions of VL should be researched before its implementation to the field. This study hypothesized that squat jump performance would be increased after different volumed VL conditions during half-squat exercise. Eighteen resistance-trained men (mean [M] ± standard deviation [SD]; age: 24.00±3.53 years; body mass: 78.37±5.53 kg; height: 179.35±7.04 cm; one-repetition maximum (1RM) half squat: 110.85±11.92 kg) voluntarily performed squat jump under unloaded and four different VL conditions (R6: six repetitions, Ruf: repetitions until failure, VL10: velocity loss thresholds 10%, VL20: velocity loss thresholds 20%) after a set of half-squat exercises at 80% of one-repetition maximum separated by at least 72 hours. The results revealed that subjects demonstrated significantly better squat jump performance in VL10, VL20, and R6 conditions than the unloaded and Ruf conditions (
Prevalence of Helicobacter pylori in symptomatic patients and detection of clarithromycin resistance using melting curve analysis
AbstractBackground:Clarithromycin is often a component of combination therapies for Helicobacter pylori eradication; however, increases in resistance rates have decreased the success of the treatment.Objective:This study was designed to determine the prevalence of H pylori infection in symptomatic patients and to detect clarithromycin resistance rates using melting curve analysis.Methods:Patients scheduled for upper endoscopy at the Endoscopy Unit of the Department of Gastroenterology, Duzce University, Medical Faculty Hospital, Konuralp/Duzce, Turkey, were assessed for enrollment in the study. Two pairs of gastric biopsy specimens (antrum and corpus) were obtained from each study patient. Histopathologic examination, rapid urease test, culture, and polymerase chain reaction (PCR) of the specimens were used to identify H pylori infection. Clarithromycin resistance was detected using melting curve analysis.Results:Seventy-five patients (41 women, 34 men; mean [SD]age, 42.6 [14.5] years [range, 17–70 years]) were included in the study. Using histopathology and rapid urease test, H pylori was detected in 40 (53.3%) of the 75 specimens. H pylori was detected using PCR in 40 (53.3%) specimens and by culture in 10 (13.3%) specimens. The specificity and sensitivity of PCR and culture were interpreted by comparing them with the results of histopathologic examination and urease tests. The specificity and sensitivity of PCR were 68.6% and 72.5%, respectively, and the specificity and sensitivity of culture were 97.1% and 22.5%, respectively. Of the 40 isolates, 21 (52.5%) were susceptible to clarithromycin, 12 (30.0%) were resistant, and a mixed susceptibility pattern was detected in 7 (17.5%) specimens. H pylori isolates from 19 (79.2%) of the 24 patients who had formerly used clarithromycin showed clarithromycin resistance.Conclusions:The prevalence of H pylori infection was 53.3% for the symptomatic patients in this study, and 47.5% of the isolates showed clarithromycin resistance using melting curve analysis. The PCR-based system used in this study was accurate for the detection of H pylori infection as well as clarithromycin susceptibility testing directly in biopsy specimens
