detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. this distribution could be detected by different geophysical methods, especially gravity method. however, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. performance of the gravity technique co...

Mathematical model of the genetic sequential logic circuit Based on a previously defined model (Bintu et al. 2005), we employed a set of ordinary differential equations to describe the dynamic process of our genetic sequential logic circuit. The circuit’s variables, such as the concentrations of mRNAs and proteins, were plot as functions of time in response to external stimulus. In order to red...

Steady, Darcian, 1-D, 1-phase evaporation through a vertically inhomogeneous soil from a horizontal water table is simulated as an optimal control problem, i.e. the hydraulic properties of the porous medium (relative permeability of moisture and capillary water retention curve) are considered as control functions. The Richards nonlinear ordinary differential equation is integrated twice as a bo...

A 24-year-old man presented with a palpable mass in the deep superonasal quadrant of the left orbit which had been present for one year. He had no visual complaints, yet noted multiple hard masses at the right and left mandibular angles. The patient had history of a similar mass in his right orbit which had prompted surgical intervention 2 years earlier. Histopathological evaluation of the righ...

Multiple adenomatous colon polyps. An adenomatous polyp is an area where the normal cells that line the inside of the colon and begin to make mucous and form a mass on the inside of the intestinal tract. Benign (noncancerous) tumors, including: sebaceous cysts (closed sac filled with liquid found under the skin) epidermoid cysts (lumps in or under the skin often filled with liquid) fibromas (fi...

dans une conception traditionnelle, l’intelligence est fixée et peut être mesurée par un nombre dans un contexte déconnecté de toute réalité et s’attribuer une forme unique. dans une vision nouvelle, en se basant sur la théorie des intelligences multiples de gardner, l’intelligence a  en revanche de différentes composantes et peut être développée  durant toute la vie. le présent article s’intro...
