Sodium-hydrogen exchanger regulatory factor-1-deficient (NHERF-1(-/-)) mice demonstrate increases in the urinary excretion of phosphate, calcium, and uric acid associated with interstitial deposition of calcium in the papilla of the kidney. These studies examine the role of NHERF-1 in the tubular reabsorption of uric acid and regulation of mouse urate transporter 1 (mURAT1), a newly described t...

In this paper, we study various dissipative mechanics associated with the Boussinesq systems which model two-dimensional small amplitude long wavelength water waves. We will show that the decay rate for the damped one-directional model equations, such as the KdV and BBM equations, holds for some of the damped Boussinesq systems.

From a spectral method combined with a predictor-corrector scheme, we numerically study the behavior in time of solutions of the three-dimensional generalized Kadomtsev-Petviashvili equations regularized using the BBM trick. The solution no longer blows up and the solitonic behavior is observed.

The BBM or Regularized Long Wave Equation is shown to possess only three non-trivial independent conservation laws. In order to prove this result, a new theory of Euler-type operators in the formal calculus of variations will be developed in detail.

ammonia (nh3) and nitrite (no2) toxic chemicals which resulted from fish culture, especially in intensive fish culture systems. to evaluate the efficiency of green algae scenedesmus quadricauda in ammonia and nitrite removal from intensive fish farm effluent and also its application as suitable culture medium for s. quadricauda , effluent water samples were collected from rainbow trout farm. si...

Mechanical advantage of the muscles controlling flexion and extension of the elbow joint has been a focus of many primate locomotion studies. These studies have tended to concentrate on either the triceps brachii muscle (TBM), an elbow extensor, or the biceps brachii muscle (BBM), an elbow flexor. The anatomical mechanical advantage (AMA) of these muscles, an approximation of their effective me...

Yanling Ju Ph.D., Purdue University, May 2015. Black-Box Printer Models and their Applications. Major Professor: Jan P. Allebach. In the electrophotographic printing process, the deposition of toner within the area of a given printer addressable pixel is strongly influenced by the values of its neighboring pixels. The interaction between neighboring pixels, which is commonly referred to as dot-...

Background Bee venom (BV) has been widely investigated for potential medical uses. Recent inadvertent uses of BV based products have shown to mitigate signs of fungal infections. However, the component mediating the antifungal effect has not been identified. Objective This investigation compares bee venom in its whole and partial forms to evaluate the possible component responsible for the an...

We prove that the initial value problem (IVP) for the BBM equation is ill-posed for data in H(R), s < 0 in the sense that the flow-map u0 7→ u(t) that associates to initial data u0 the solution u cannot be continuous at the origin from H(R) to even D′(R) at any fixed t > 0 small enough. This result is sharp.
