Magnetic iron oxide nanoparticles have gained a lot of attention in drug delivery systems because they can control a drug pathway to deliver it to the specific site under a magnetic field which is related to their magnetic core and surface coating. Chitosan-coated FeNPs, have prominent antimicrobial and biological properties that make chitosan a promising biopolymer for drug delivery applicatio...

The more accurate the forecast is to lot delivery time, the more effective it is in fab scheduling. In fab operations, scheduling is the major impact factor of tools capacity allocation, tools utilization control and bottleneck management. However, there is no effective method to estimate delivery time in 300 mm automatic material handling systems (AMHS) operation. Computer simulations are auth...

Background older people may be less likely to receive interventions than younger people. Age bias in national guidance may influence entire public health and health care systems. We examined how English National Institute for Health & Care Excellence (NICE) guidance and guidelines consider age. Methods we undertook a documentary analysis of NICE public health (n = 33) and clinical (n = 114) g...

in this paper, the problem of lot sizing, scheduling and delivery of several items in a two-stage supply chain over a finite planning horizon is studied. single supplier via a flexible flow line production system (ffl) produces several items and delivers them directly to an assembly facility. based on basic period (bp) strategy, a new mixed zero-one nonlinear programming model has been develope...

abstract background: labor is a physiologic process, and consideration of labor pain and relieving that is among the major components of maternal care. application of some labor position can lay the fetus better in pelvic canal direction. the present study aimed to investigate the effect of laying the mother in three labor positions on the pain severity in the second, third, and fourth stages o...
