introduction: serum anti endothelial cell antibodies (aecas) play a prominent role in idiopathic sensorineural hearing loss (snhl) in that they induce vascular damage (immune mediated).the of the current study is  to compare aecas in serum and perilymphatic .uid of idiopathic snhl children (<15y) undergoing cochlear implant surgery.methods: this was a cross sectional study performed in the coch...

The processing of seawater by the marine teleost fi sh intestine includes high rates of base (bicarbonate) secretion into the intestinal fl uids. The resulting high bicarbonate concentrations in the intestinal fl uids combine with the calcium in the ingested seawater to form calcium carbonate crystals. This process is important for the salt and water balance of the marine teleost fi sh and lead...

constraints: time evolution of the adiabatic piston Christian Gruber Institut de physique th eorique Ecole Polytechnique F ed erale de Lausanne CH-1015 Lausanne, Switzerland June 22, 1998 Abstract The equations for the time evolution of the controversial adiabatic piston problem are obtained using a very primitive model of the uids. It thus shows that the 1st and 2nd laws of thermodynamics lead...

Effective thermal conductivity of mixtures of  uids and nanometer-size particles is measured by a steady-state parallel-plate method. The tested  uids contain two types of nanoparticles, Al2O3 and CuO, dispersed in water, vacuum pump  uid, engine oil, and ethylene glycol. Experimental results show that the thermal conductivities of nanoparticle– uid mixtures are higher than those of the bas...

Background: Intraosseous injection is a way to administration of drugs. Objective: The clinical comparison of intraosseous and intravenous injection of Thiopental-Na. Methods: First all birds (Twenty six healthy pigeons) were split out into two groups randomly. Group A received 20 mg kg-1 Thiopental-Na by intraosseous rou...

background: ferula persica has been used in traditional medicine for treatment of high blood pressure. in this study acute and chronic effect of aqueous f. persica extract on bp of hypertensive rats and its possible mechanism of action have been investigated. methods: eighty two male wistar rats were divided into 12 experimental groups. hypertension was induced by goldblatt method in the anesth...

We study a general multiple layer Rayleigh-Taylor instability problem for both compressible and incompressible inviscid uids. Our main result is that many features of a multilayer system are universal, in the sense they do not depend on such details as the number of layers, their thicknesses, equations of state for the uids, and equilibrium density distributions. It is shown that a compressible...

SOMMARIO Si adatta la teoria generale dei girocontinui sviluppata in 1] per applicazioni nel caso dei uidi perfetti con spin e degli iperruidi 9]. Ovvi cambiamenti sono necessari a causa dell'interesse principalmente rivolto ai solidi in 1]; nel caso presente, in aggiunta a quanto ABSTRACT The general theory of gyrocontinua developed in 1] is adapted to apply to perfect spin uids and hyperruids...

We consider an energy-functional describing rotating superruids at a rotating velocity !, and prove similar results as for the Ginzburg-Landau functional of su-perconductivity : mainly the existence of branches of solutions with vortices, the existence of a critical ! above which energy-minimizers have vortices, evaluations of the minimal energy as a function of !, and the derivation of a limit...
