This paper focuses on a hydraulic radius separation approach used to calculate the boundary shear stress in terms of bed and wall shear stress proposed in a trapezoidal channel. The average bed and sidewall shear stress in smooth trapezoidal open channels are derived after using Guo & Julien (2005) early equations taking a part of an investigation to cover both rectangular and trapezoidal chann...

We present a case of reactive amyloidosis that developed secondary to common variable immunodeficiency and rheumatoid arthritis. A 66-year-old woman, with prior history of common variable immunodeficiency and rheumatoid arthritis, was referred to our clinic for chronic diarrhea investigation. The patient was submitted to colonoscopy with ileoscopy, which did not show relevant endoscopic alterat...

This paper intends to offer a modeling of the magnitude of arsenic, by using 54 variables of chemical elements based on secondary data. The samples are collected from 113 wells from different areas of Bangladesh. The study shows that 9 variables are significantly related with the arsenic variable. Analysis also claims that arsenic variable can be modeled with three principal components (a linea...

An outcome variable is one which we hope to change, predict or estimate in a trial. Examples: • Systolic blood pressure in a hypertension trial • Caesarean section rate in an obstetric trial • Survival time in a cancer trial How many outcome variables should I have? If we have many outcome variables: • all possibilities would be covered, • we would be less likely to miss something, • the risk o...

In [P] R. Pellikaan introduced a two variable zeta-function Z(t, u) for a curve over a finite field Fq which, for u = q, specializes to the usual zeta-function and he proved, among other things, rationality: Z(t, u) = (1 − t)−1(1 − ut)−1P (t, u) with P (t, u) ∈ Z[t, u]. We prove that P (t, u) is absolutely irreducible. This is motivated by a question of J. Lagarias and E. Rains about an analogo...

Tetrad correlations were obtained historically for Gaussian distributions when tasks are designed to measure an ability or attitude so that a single unobserved variable may generate the observed, linearly increasing dependences among the tasks. We connect such generating processes to a particular type of directed graph, the star graph, and to the notion of traceable regressions. Tetrad correlat...

replacement (TAR) in patients with advanced ankle osteoarthritis (OA). AJD could a tenable option to ankle fusion orTAR.Methods: A review has been performed on the role of AJD in advanced OA of the ankle. The exploration machinewas MedLine. The keywords utilized were: joint distraction ankle. Three hundred and eleven articles were found. Ofthe above-mentioned, only 14 were chosen and analyzed b...

In this paper, we propose a new, two-stage, adaptive classified pattern-matching algorithm based on residual vector quantization and variable bit rate encoding techniques as they have proved to be very efficient in progressive image transmission and compression rate. Both the intra-block and inter-block correlation properties have been exploited to enhance the compression rate. The innovative a...
