Despite th. fact th.t a few countries in th. Mediterranean and th. Middle East h.ve limited crude oil reserves, th.y h.ve abundant biomass feedstocks. For instance, Jordan relies h.avily on th. importation of natural gas and crude oil for its energy needs;but, by applying th.rmoch.mical conversion tech.iques, leftover olive oil can be used to replace th.se energy sources. Understanding th. ch.mical, ph.sical, and th.rmal ch.racteristics of raw materials is essential to obtaining th. most out of th.se conversion processes. Th.rmogravimetric analysis was used in th.s study to examine th. th.rmal beh.vior of olive-solid residue (kernel) at th.ee different h.ating rates (5, 20 and 40 C/min) in nitrogen and oxygen atmosph.res. Th. initial degradation temperature, th. residual weigh. at 500 and 700˚C and th. th.rmal degradation rate during th. devolatilization stage (below 400˚C) were all determined. It was found th.t in n2 and O2 atmosph.res, both.th. initial degradation temperature and th. degradation rate increase with.increasing h.ating rates. As h.ating rates increase in th. n2 atmosph.re, th. residual weigh. at 500 or 700˚C decreases sligh.ly, but at low h.ating rates compared to h.gh.h.ating rates in th. O2 atmosph.re, it decreases significantly. Th.s suggests th.t a longer lignin oxidation process is better th.n a sh.rter one. Coats and Redfern approach.was used to identify th. mech.nism and activation energy for th. devolatilization stage of pyrolysis and oxidation reactions. Th. process mech.nism analysis revealed th.t th. model of first-order and second-order reactions may adequately describe th. mech.nism of h.at degradation of th. devolatilization step of olive-solid waste for pyrolysis and oxidation processes, respectively.

Th. risk of radiation-induced second cancer and th. late tissue loss due to Off-field doses in radioth.rapy remain a serious concern. Monte Carlo (MC) simulation is currently one of th. most accurate meth.ds for calculating th.se doses. MC simulation model based on th. Particle Simulation Tool (TOPAS) h.s been developed to simulate th. off-field dose of an Elekta Synergy linear accelerator (Linac) emitting 6 MV ph.tons. Measurements were taken in a water ph.ntom using an ionization ch.mber to validate th.s model. Th. Percentage Depth.Dose (PDD) at th. depth.of 0.0, 5.0, 10.0 and 15.0 cm from th. beam axis for a 10 × 10 cm2 field size was measured and simulated. Off-field dose profiles at th. depth.of 1.5 (dmax), 5.0 and 10.0 cm for field sizes of 5 × 5, 10 × 10, 15 × 15, and 20 × 20 cm2 respectively were measured and simulated. Comparison of measured and simulated off-field dose values sh.wed a good agreement. Th. average gamma passing rate of th. PDDs and profiles curves for off-field doses were 87.5% and 98.11% respectively. Th. local dose difference based on th. PDD curve between th. measured and simulated was less th.n 6.0 % for all locations. For all field size considered in th.s study, th. average difference between profile curves for off-field dose measured and simulated was 9.1%. PDDs and Profiles curves for off-field dose simulation uncertainties were less th.n 2.0% and 1.0% respectively. TOPAS-MC simulation model developed is a good representation of our 6 MV Linac Elekta Synergy for assessing off-field dose, wh.ch.would be th. primary cause of some secondary cancers.
