Proizvodne varijable koje utječu na svojstva peleta u peletiranju taljenjem sa smjesom voskova u sferonizatoru za laboratorijsku proizvodnju

The purpose of the study was to evaluate the suitability of laboratory scale spheronizer for the production of spherical pellets loaded with diltiazem hydrochloride by wax combination. The 1:1 combination of cetyl alcohol and hydrogenated castor oil, as low and high melting point waxes, were used. The various production variables affecting the different characteristics of pellets and the process efficiency were evaluated. Drug loaded pellets were evaluated for drug release in distilled water. Bowl temperature primarily affects the sphericity and adhesion of pellets to the bowl. Mass temperature has a pronounced effect on size, size distribution and sphericity of pellets. Wax concentration affects all characteristics of pellets but adhesion was least affected. The effect of these three variables can be compensated by optimizing the friction plate speed. It has been found that the highest yield of pellets (8501400 m) with maximum sphericity can be produced by using 45 C bowl temperature, 52 C mass temperature and 1400 rpm friction plate speed.Cilj rada bio je pripraviti sferične pelete u laboratorijskom sferonizatoru koristeći smjesu voskova. Cetilni alkohol kao vosak niskog tališta i hidrogenirano ricinusovo ulje kao vosak visokog tališta, upotrebljeni su u omjeru 1:1. Proučavan je utjecaj proizvodnih varijabli na svojstva peleta i efikasnost proizvodnje te brzinu oslobađanja ljekovite tvari iz peleta u destiliranoj vodi. Na sferičnost i adhezivnost peleta najviše utječe temperatura peletiranja. Temperatura mase ima i značajan utjecaj na veličinu, raspodjelu veličine peleta i sferičnost. Koncentracija voska utječe na sva svojstva peleta, ali najmanje na adhezivnost. Učinak tih triju varijabli može se kompenzirati optimiziranjem brzine ploče za trenje. Pronađeno je da najveće iskorištenje peleta (8501400 microm) s najboljom sferičnošću ako je temperatura peletiranja 45 oC, temperatura mase 52 oC, a brzina ploče za trenje 1400 rpm

Doura-Eropos.

The present article is an analysis of the monumental work of the Belgian archæologist and savant, M. Franz Cumont, which embodies the results of excavations made by him on the site of the ancient Macedonian colony of Doura-Eropos. As it was impossible to give a mere resumé of this work without leaving out some of the important points and erudite suggestions which are scattered in the text and valuable foot-notes, I thought it best to give as clear and as complete an idea as possible of this once important and flourishing Macedonian colony situated in the heart of the Syrian desert. Further, speaking from the purely Iranian standpoint, the excavations atDoura-Eropos have furnished new documents pertaining to the Parthian civilization, which had penetrated into Parapotamia with its Parthian conquest, and which had left its traces not only in the costume of priest and soldiers, but also in fine arts—in sculptures and paintings, in ceramics and jewellery, as can be amply proved by the results of the excavations of 1928 and 1929.</jats:p
