Examplesofhydrocarbonhydrocarbon The stoichiometry of the exact reaction will depend on the nature of the organic matter involved, here assumed to be saturated aliphatichydrocarbon. From theCambridge English Corpus There is a need to understand the fate and behaviour ofhydrocarboncontaminants in these extreme systems. From theCambridge English Corpus The total quantity of hydrocarbons (sum of singlehydrocarbonquantity) is expressed here as quantity of hydrocarbons in ng/mg of insect. From theCambridge English Corpus The proportions of these hydrocarbons increased in extracts of parasitized honey bees. From theCambridge English Corpus The highest increase among relative proportions of hydrocarbons was observed with unsaturated hydrocarbons (around 15 % versus 9 %). From theCambridge English Corpus Maturation of the organic matter in the vicinity of the intrusion can lead to the generation of liquid hydrocarbons. From theCambridge English Corpus Nevertheless, the effect of evaporation and other natural degradation processes through the years might have contributed to lowerhydrocarbonconcentrations. From theCambridge English Corpus There is a significant reduction inhydrocarbonconcentrations in sediments as the distance from the assumed hydrocarbon sources (contaminated sites located uphill) increases. From theCambridge English Corpus Table 1 shows thehydrocarbonquantities given as the mean nanograms per fly of each compound or mixture from the two peaks of interest. From theCambridge English Corpus Parasites, if they possess quantities of epicuticular hydrocarbons near the threshold level necessary to be perceived by hosts, could be more tolerated by hosts. From theCambridge English Corpus No qualitative differences in thehydrocarbonprofiles was observed with regard to gender though preliminary results showed that quantitative differences were clearly present. From theCambridge English Corpus Issues and problems relating to fishing,hydrocarbonexploration, tourism and communications clearly spill over national borders (regardless of whether those borders are actually contested). From theCambridge English Corpus It was postulated that the movement of water throughhydrocarbon-contaminated sediments would result in the dispersal of hydrocarbon-contaminated meltwater downhill towards the sea. From theCambridge English Corpus However,hydrocarbon(toluene) emissions were more than 250% higher than totalhydrocarbonemissions from other sources on station. From theCambridge English Corpus It will be less useful for those working on oceanic lithosphere,hydrocarbongeology or mineralization processes.
