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 ...
Objective- This survey was accomplished to describe the hepatic artery and portal vein indices in healthy domestic cats by color Doppler ultrasonography technique. Design- Retrospective experimental study. Animals- Twenty domestic short hair (DSH) cats (10 males and 10 females). Procedures- Doppler indices of ...
Pathologic changes of the recipient native portal venous system may cause thrombosis of the portal vein, especially in pediatric living donor liver transplantation (LDLT). This study assessed the utility of Doppler ultrasound (US) for the detection of intraoperative portal vein occlusion and identification of predisposing risk factors in the recipients. Seventy-three pediatric recipients who un...
