here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
bisphenol a, 2,2-bis(4,4-dihyroxyphenyl propane) is the raw material for the production of important synthetic polymers such as epoxyresins, polycarbonates and polysulphones. during the last twenty years the anual production of bisphenol-a has been continuously increasing. a,b,c cqrves shows the consumption pattern of bisphenol-a (19601972) • epoxy resins are used for the production of adhessiv...

I n this paper, the evaluation of the real exchange rate transfer and the asymmetric transmission of real exchange rate fluctuations to the export prices of food products for the country during the period (2001-2015) was studied using two approaches of PMG and GMM systems. The TGARCH method was used to calculate the real exchange rate fluctuation index and the Markov Switching method was u...
This paper studies the structure of cost and production of rice using cross section data from rice farming in Guilan in 1997. A translog cost function is specified for this purpose and estimated, using Iterative Seemingly Unrelated Regressions for both the short and the long run where all factors are taken to be variables. The results of the study are as follows: 1. Neither in the short-run nor...
