در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...
Chitosan Microspheres as Potential Vaccine Delivery Systems
The recent advances in controlled delivery systems for protein pharmaceuticals such as microspheres, liposomes, pumps and implants, have provided a new avenue for delivery of vaccine antigens. Adjuvants aimed at increasing the immunogenicity of recombinant antigens remain a focus in vaccine development worldwide, there is currently considerable care for the development of chitosan microspheres ...
متن کاملFormulation and Evaluation of Magnetic Microspheres Of Cytarabine
Cytarabine is the drug of choice for treatment of leukemia. However, many formulations have been prepared, due to certain limitations they could not prove to be effective ones, therefore magnetic microspheres are formulated as they minimize the Reticuloendothelial clearance and target site specificity can be increased. The current study aimed to utilize nanotechnology to develop magnetic micros...
متن کاملPreparation of Ethylcellulose Coated Gelatin Microspheres as a Multiparticulate Colonic Delivery System for 5-Aminosalicilic Acid
In the long-term management of ulcerative colitis patients, repeat dosing maybe required. Since 5-ASA is largely absorbed from the upper intestine, selective delivery of drugs into the colon may be regarded as a better method of drug delivery with fewer side effects and a higher efficacy. The aim of this study was to prepare and evaluate a double coated multiparticulate system for 5-ASA deliver...
متن کاملFormulation and Evaluation of Mucoadhesive Microspheres for Intra -nasal Delivery
Intranasal administration is an ideal alternative to the parenteral route for systemic drug delivery. Various conventional dosage forms have been employed for this purpose but they lack to provide the desired bioavailability of the drug due to poor residence time and faster clearance in the nasal cavity. Formulating multiparticulate system with mucoadhesive polymers may provide a significant in...
