An ;in-vitro' technique is described for measuring quantitatively the absorption and secretion of water and electrolytes, the short circuiting current, and the simultaneous bidirectional flux rates of ions across the healthy and diseased colonic mucosa. The results show that the normal colon absorbs both sodium and water and secretes potassium. In both ulcerative colitis and Crohn's disease the...

We consider the simultaneous estimation of an optical flow field and an illumination source term in a movie sequence. The particular optical flow equation is obtained by assuming that the image intensity is a conserved quantity up to possible sources and sinks which represent varying illumination. We formulate this problem as an energy minimization problem and propose a space-time simultaneous ...

We present a simple, noninvasive method for simultaneous measurement of flow velocity and inference of liquid viscosity in a microfluidic channel. We track the dynamics of a sharp front of photobleached fluorescent dye using a confocal microscope and measure the intensity at a single point downstream of the initial front position. We fit an exact solution of the advection diffusion equation to ...

Two validated uv spectrophotometric methods for the simultaneous estimation of Febuxostat and Diclofenac in a multicomponent dosage form have been developed, utilising simultaneous equation and absorbance ratio method. The method is based on the measurement of absorbance of Febuxostat and Diclofenac at their respective wavelengths of 315 nm and 282nm and at the iso absorptive wavelength of 288 ...

This paper instigates the multivariate generalization of widely used Cauchy inequality 1 + x ≤ ex where can be any non-negative real number. The results this study solution for Cauchy’s problem particular Ordinary Differential Equation (ODE). is also related to complete monotone function and divided differences theory. proof based on empty product convention notion Beppo Levi theorem Monotone c...

There has been great interest in developing nonlinear structural equation models and associated statistical inference procedures, including estimation and model selection methods. In this paper a general semiparametric structural equation model (SSEM) is developed in which the structural equation is composed of nonparametric functions of exogenous latent variables and fixed covariates on a set ...

Simple, sensitive, and specific spectrophotometric methods were developed and validated for quantitation of diclofenac potassium and tizanidine in tablet dosage form. Three new analytical methods were developed based on the simultaneous estimation of drugs in a binary mixture without previous separation. In multiwavelength technique, the binary mixture was determined by mixed standards and thre...

Bayesian inference about small areas is of considerable current interest, and simultaneous intervals for the parameters for the areas are needed because these parameters are correlated. This is not usually pursued because with many areas the problem becomes difficult. We describe a method for finding simultaneous credible intervals for a relatively large number of parameters, each corresponding...
