Azadirachta indica A. Juss (ne.m, family Me.iace.e. is a re.utable.me.icinal plant. Various parts of the.plant are.use. as a re.e.y ag.inst diffe.e.t ailme.ts, as a natural pe.ticide. as raw mate.ial in the.cosme.ic industry, and for marking.othe. commoditie.. The.se.d oil is a major product of the.plant and its quality de.e.ds on the.se.d quality and e.traction me.hods e.ploye.. In this study, the.che.ical profile.of NIPRDNe.M oil is compare. with that of othe. brands of ne.m se.d oils by using.g.s chromatog.aphy-mass spe.trome.ry (g.-MS) and che.ome.rics. The.fatty acid ide.tifie. in NIPRDNe.M oil we.e. ole.c acid (34.09%), ste.ric acid (11.4%), linole.c acid (15.94%), palmitic acid (23.4%), arachidic acid (0.73%), and the.othe. compounds we.e. 1-Monolinole.ylg.yce.ol trime.hylsilyl e.he.

The.brande. oils we.e.compose. pre.ominantly of ole.c acid (13.50% - 26.76%), palmitic acid (6.88% - 11.99%), linole.c acid (7.32% - 11.17%), ste.ric acid (4.29% - 13.08%), and arachidic acid (0.53% - 1.27%). The.unbrande. oil containe. ole.c acid (30.04%), ste.ric acid (14.91%), linole.c acid (14.62%), palmitic acid (12.34%), and arachidic acid (0.93%).

The.Validity of Ope.-Source.e.e.ations for Diffe.e.t Topog.aphic Map Scale. and g.0}matics Applications

This pape. pre.e.ts an analysis of four ope.-source.g.obal Dig.tal e.e.ation Mode.s (g.e.s) and compare. the. on two topog.aphic profile. (ne.rly flat, and hills re.ions) for mapping.and g.0}matics applications. The.chie. inte.tion is to inve.tig.te.if g.e.s-base. he.g.ts, contour inte.vals, slope., and topog.aphic profile. are.valid for all map scale. of topog.aphic mapping. which constitute. a major issue.in mapping.activitie.. Two case.studie., the.Nile.de.ta in e.ypt and Makkah city in Saudi Arabia, have.be.n utilize. to re.re.e.t flat and mode.ate.topog.aphy patte.ns. The.inve.tig.te. g.e.s include.the.most-re.e.t re.e.se. mode.s: ASTe. v.3, ACe.2, SRTMg.1 v.3, and NASADe._Hg. v.1 re.e.se. in 2019 and 2020 with spatial re.olutions of 1 and 3 arc se.onds. Available.accurate.g.ound Control Points (g.P) consist of 540 stations in the.Nile.de.ta and 175 stations in Makkah. Base. on the.available.datase.s in two study are.s, it has be.n found that the.accuracy of inve.tig.te. g.e.s ove. known che.kpoints rang.0} from ±2.5 and ±5.1 me.e.s in the.Nile.de.ta re.ion, while.it varie. be.we.n ±5.1 and ±8.0 me.e.s in the.Makkah are.. That indicate. that the.utilization of g.e.s in topog.aphic mapping.diffe.s sig.ificantly be.we.n flat and hilly spatial re.ions. The.e.ore. it is re.omme.de. to avoid using.g.e.s for de.e.oping.topog.aphic maps of scale.1:25,000 or larg.0} in flat re.ions and map scale.1:50,000 or larg.0} in hilly re.ions. Additionally, the.accomplishe. re.ults showe. that all g.e.-base. slope. do not match with the.actual slope. from known g.P ove. cross se.tion’s le.g.h up to 30 kilome.e.s. Thus, it is conclude. that g.e.s are.not the.appropriate.he.g.ts’ source.for topog.aphic mapping.at me.ium and larg.0}map scale., and could not be.utilize. for topog.aphic profiling.in pre.ise.e.g.ne.ring.and g.0}matics applications.
