Emergence, survival and growth of selected plant species in petroleum-impacted flare pit soils

Canadian Journal of Soil Science, 2005
One of the prerequisites to phytoremediation of hydrocarbon-contaminated soils is that plants be able to germinate and become established in the presence of contaminants. This 5-wk growth chamber study examined the tolerance of five grasses and one legume to petroleum hydrocarbons (PHCs) and associated salts in three weathered, fine-textured, flare ...

Study on plants and their ecological characteristics in the sand pit regions of Moscow

Research on Crops, 2020
Industrial activity of human being, with each passing year, leaves an ever-growing danger on the environment worldwide. The extraction of mineral soil and non-metallic materials from sand pits has caused serious damage to the environment. Damage was embodied by soil cover destruction which occur at mining sites followed by processing of minerals and ...

Study on Structural Integrity Analysis of Tubular Reactor With Corrosion Pits in LDPE Plant

Volume 1B: Codes and Standards, 2013
Ultrahigh pressure polyethylene tubular reactors were widely used in Petrochemical Industry. Because of corrosion, fatigue crack and other defects easily caused by a high operating pressure and complicated operating conditions for tubular reactor, their safety was a concerned issue in the engineering field.

Improved method for visualizing coated pits, microfilaments, and microtubules in cryofixed and freeze-substituted plant cells

Journal of Electron Microscopy, 2002
We have optimized the conditions for visualizing microfilaments, microtubules, and coated pits in the cortical cytoplasm of high-pressure frozen and freeze-substituted plant cells, in both tobacco root tips and onion cotyledons, individual microfilaments and the supramolecular structure of coated pits can be seen clearly in freeze-substituted samples ...

Field Experiences for SRB-MIC Control in Water Injection Plants Having Continuous Pit Recovered Fluids

CORROSION 2003, 2003
Abstract This article describes the experiences for SRB-MIC Control in a water plant with fluid recovered from a disposal pit through the use of different biocide treatment strategies, and a comparison of the cost-effectiveness of the different products used to control MIC, such as glutaraldehydes, quaternary ammonium, acrolein and THPS.

Enhancing efficiency of fertilizer n use in sugarcane by ring-pit method of planting

Sugar Tech, 2004
Nitrogen use efficiency of sugarcane variety CoS767 was measured in terms of partial factor productivity (PFP) and agronomic efficiency (AE) of applied N through a field experiment conducted during spring season in a sandy loan alluvial entisol soil at the Indian Institute of Sugarcane Research, Lucknow (26.50 N, 80.50 E and 120 m amsl).

Pitting Corrosion of Stainless Steel by Potable Municipal Water in an Organic Chemical Plant

1992
Abstract Several tubes in a 35 m2 (115 ft2) type 316 stainless steel shell-and-tube condenser leaked unexpectedly in an organic chemical plant that produces vinyl acetate monomer. Leaks were discovered after 5 years of operation and relocation of the condenser to another unit in the same plant.

NATIVE AND NONNATIVE PLANT COLONIZATION IN PITS AND ADJACENT BLOWDOWN AREA AFTER A HURRICANE

2006
Soil disturbance from hurricane blowdowns may contribute to an increase in nonnative plant species invasion. Two years after a wind disturbance in a Mid-Atlantic hardwood forest, I compared fifty-two, 1.0 m x 0.5 m tree blowdown pit plots and paired nonpit plots for plant percent cover.
