The corpus allatum (CA) of adult female Ceratitis capitata produces methyl palmitate (MP) in vitro, in addition to JHB(3) and JH III. Biosynthesized MP migrates on TLC and co-elutes from RP-18 HPLC with synthetic MP. Its identity is verified herein b

Drilling in the eastern continental margin of the Levant Basin (southeastern Mediterranean), offshore southwestern Israel encountered light oil shows, numerous vertically stacked gas pockets and, more recently, commercial gas discoveries. Chemical an

A combined palladium–rhodium catalyst, generated by silica sol–gel-co-entrapment of metallic palladium and [Rh(cod) (-Cl)]2, catalyzes under ambient conditions the hydrogenation of toluene and other simple benzene derivatives. The catalyst is per

The heteronuclear complexes [(CO)4Fe(μ-PPh2)Pd(μ-Cl)2]2, [Et4N][FeCo3(CO)12] and Rh2Co2(CO)12 were physically entrapped in SiO2–sol–gel matrices. The doped materials, so formed, were utilized as recyclable catalysts for (a) selective isomerizat

We present a study of 45 oil samples from the Tataria and Perm basins in the Volgo-Ural region, Russia. Crude samples were obtained from 30 oil fields across the two basins. Samples are from variable carbonate and sandstone reservoir rocks ranging in

Calcite crystals exposed to clay volatiles react with some components of these volatiles, giving rise to a variety of surface morphologies. F, Cl, and S in different proportions were detected by electron microprobe analysis of the calcite surfaces. U

The relative amounts of methyl palmitate (MP) during the first 10 days post-eclosion were determined in whole-body extracts of adult female Ceratitis capitata by SIM monitoring of the 74 m/z fragment. MP peaks in receptive 3-day-old virgin females co

Immature asphalts suggested to originate from early stages of catagenesis and related kerogens were submitted to various pyrolysis analyses. We have examined the idea that, under certain conditions, parts of kerogen cleave off to yield asphalt. Bulk

ESR measurements of stepwise-pyrolyzed melanoidins and humic substances (at various temperatures, mesh size, and pH values) furnished the following information: the melanoidin structure stabilizes the long-living free radicals in a manner similar to

Volatiles formed on heating clay minerals contain a variety of cations and anions and are highly reactive. Gas chromatograph-mass spectrometer analysis of long-chain n-alkanes exposed to such volatiles showed that some decomposition occurred even < 2
