The impact of light intensity on the toxicity pyrene, a 4-ring polycyclic aromatic hydrocarbon (PAH), was studied in Chlorella vulgaris and Scenedesmus acutus. Both species were cultured under low light, LL [50-60 µmol(photon) m-2 s-1], high HL [100-110 s-1] conditions to study effects pyrene (PYR) growth parameters, content biomolecules, chlorophyll content, photosynthetic efficiency. In prese...

The new synthetic form of microporous crystalline silica, denoted as ITQ-12, shows a high potential for the separation of propane and propene from its mixtures.

The article presents the results of electromagnetic activation petroleum raw materials in vortex layer apparatus. It is shown that under influence, there a significant increase proportion straight-run gasoline fraction distillate, as well change physicochemical parameters light fractions obtained. established processes wave action on oil, which take place zone field, lead to group hydrocarbon c...

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...

Hybrid clones segregating human chromosomes were prepared by fusing mouse RAG cells to fresh human bone marrow cells and tested for the mixed-function oxygenase [flavoprotein-linked monooxygenase; RH, reduced-flavoprotein:oxygen oxidoreductase (RH-hydroxylating); EC 1.14.14.1] arylhydrocarbon hydrocarbon hydroxylase. Neither constitutive nor induced aryl hydrocarbon hydroxylase activity was det...

Hydrocarbon profiles on the cuticle of social insects act as multi-component recognition cues used to identify membership in a species, a colony or, within colonies, cues about its reproductive status or task group. To examine the role of structural complexity in ant hydrocarbon recognition cues, we studied the species recognition response of two ant species, Linepithema humile and Aphaenogaste...

The entrapment of residual hydrocarbon ganglia during water table fluctuations can produce a long-term contamination threat to groundwater supplies that is difficult to remove. The mobilization of entrapped hydrocarbon ganglia depends on the balance between capillary and gravitational forces represented by the Bond number. The present work focuses on the influence of the interfacial tension bet...
