This paper introduces a new algorithm bio-inspired on organic chemistry for approximation problems, named artificial hydrocarbon networks (AHN). In fact, hydrocarbon compounds present characteristics as stability, well-forming structures, and easily-spanning; properties that are needed modeling problems. Actually, artificial organic networks are also presented as basis of AHNs. The description ...

Acute static bioassays were conducted with 13 pesticides to determine their comparative toxicity to fish. There was a wide range in the toxicity of these compounds with 96-hour TLm values ranging from 0.0033 to 4.0 mg/1. Of the compounds tested, Thiodan, a chlorinated hydrocarbon, and Thimet, an organic phosphorus pesticide, were the most toxic; and Bayer 29493, an organic phosphorus compound, ...

bioremoval and bioreduction activities of hydrocarbon (diesel) isolation from environmental samples were studied by the activity of biosurfactant production, and calculating emulsification index, gravimetric, and ftir analysis along with the estimation of bacterial biomass. sample from soil near petrol, diesel pumps and water sample from thesjaswini river near padannakad, kasaragod, kerala, ind...

Phenolic compounds derived from biomass are important feedstocks for the sustainable production of hydrocarbon biofuels. Hydrodeoxygenation is an effective process to remove oxygen-containing functionalities in phenolic compounds. This paper reported a simple method for producing hydrocarbons by liquefying biomass and upgrading liquefied products. Three phenolic compounds fractions (1#, 2#, and...

The quality of wide a variety of synthetic or naturally occurring materials which are used for outdoor applications are known to be adversely affected by environmental factors. These materials absorb solar ultraviolet radiation leading to changes in their structures and compositions. The consequences of these changes lead to degradation of the materials. Bitumen is one of the materials which is...

The present study aimed to analyze the concentration of aromatic hydrocarbon transfer cyclic through consumption of Binni fish (Mesopotamichthys sharpeyi) at Huralazim wetland and estimates the risk of consumption at 7 stations of Huralazim wetland in spring 2018 (one season). A statistic populations included sediment (n=21), water (n=21) and fish (n=21). The concentration of aromatic hydrocarb...

Rates of hydrocarbon biodegradation were estimated by following oxygen uptake during mineral oil oxidation or oxidation of [1-14C]hexadecane to 14CO2, when these substrates were added to natural water samples from Wisconsin lakes. A lag phase preceded hydrocarbon oxidation, the length of which depended on population density or on factors influencing growth rate and on the presence of nonhydroca...

One of the major environmental problems today is hydrocarbon contamination resulting from the activities related to the petrochemical industry. Accidental releases of petroleum products are of particular concern in the environment. Hydrocarbon components have been known to belong to the family of carcinogens and neurotoxic organic pollutants. Currently accepted disposal methods of incineration ...
