Design and synthesizing appropriate carrier for release of dexamethasone as an anticancer drug

Introduction: One of the effective drugs in the treatment of cancer is dexamethasone. Dexamethasone is known as one of the safest glucocorticoid, but there is still side-effects, due to its hydrophobicity and low bioavailability. The purpose of the present study is to design a controlled release carrier for dexamethasone in order to overcome constraints and reduce side effects. Materials and Me...

Neural-Network-Aided On-line Diagnosis of Broken Bars inInduction Motors

This paper presents a method based on neural networks to detect broken rotor bars and end rings in squirrel cage induction motors. In the first part, detection methods are reviewed and traditional methods of fault detection as well as dynamic&#10model of induction motors are introduced using the winding function method. In this method, all stator and rotor bars are considered independently in o...

Designing Effective Strategies to Improve Performance Indicators of Bread Industry Using System Dynamics: A case study in Iran

Iranian bread production methods are often unsanitary, in the last decades, different attempts were made to mechanize production of Iranian breads, but a few of them, due to a variety of factors, could succeed. The aim of this study is to examine various factors affecting the system of bread production in Iran and to provide effective solutions for the development of mechanized bakeries as the ...

Intrapelvic Protrusion of a Broken Guide Wire Fragment during Fixation of a Femoral Neck Fracture

  During fixation of a femoral neck fracture in a 23-year-old male patient with cannulated screws, a broken guide wire fragment inadvertently advanced through the hip joint and protruded into the pelvis. A second surgical approach was needed to remove the broken fragment from the pelvis. Awareness of such a potentially devastating complication will make surgeons more cautious during implementa...
