We study the monopolistic competition model with producer-retailer-consumers two-level interaction. The industry is organized according to Dixit–Stiglitz model. retailer only monopolist. A quadratic utility function represents consumer preferences. consider case of retailer's leadership; namely, we two types behavior: and without free entry condition. Earlier, obtained result: increase social w...

A method using europium-doped BaFBr imaging plates (IPs) has been developed to estimate and map values of entrance skin doses during interventional radiology (IR). IPs offer many advantages for measuring the entrance skin dose because they have a wide dynamic range (up to 100 Gy), provide high spatial resolution as a detector of two-dimensional images, and can be used repeatedly. The entrance s...

Membrane rejection models generally neglect the effect of the pore entrance on intrapore particle transport. However, entrance effects are expected to be particularly important with ultrathin membranes, where membrane thickness is typically comparable to pore size. In this work, a 2D model was developed to simulate particle motion for spherical particles moving at small Re and infinite Pe from ...

Purpose. This cross-sectional, observational study used Fourier-domain optical coherence tomography (OCT) to examine the position, patency, and the interior entrance site of anterior chamber (AC) aqueous tube shunts. Methods. The OCT, slitlamp biomicroscopy, and gonioscopy findings of 23 eyes of 18 patients with AC shunts were collected and compared. Results. OCT images demonstrated the shunt p...

This study attempts to reveal that the entrance design elements and physical features attributes of entrance of the institutes of technical education has the ability in inducing perceived image among the observers about the technical Institutes in Tiruchirappalli and Thanjavur region. Furthermore, to establish that perceived image of a setting is a function of legibility of design elements and ...
