Modifications and Improvements on CEN/BII Profiles
2012This paper introduces a new approach to modeling of e-Ordering and e-Invoicing solutions. Today, electronic means to conduct purchases and sales are essential activities for companies operations, and they need to decide how to implement e-Ordering and e-Invoicing, what software solutions to use, and how to integrate them successfully with their current

A Problem of Hydrocarbon Profile Modification by Charcoal
Journal of Forensic Sciences, 1989Abstract A selective modification of mineral turpentine in the presence of charcoal was observed to the extent that the trace resembles evaporated or “weathered” petrol.

Analysis and Modification of Ergot Alkaloid Profiles in Fungi
2012The ergot alkaloids are a family of secondary metabolites produced by a phylogenetically discontinuous group of fungi. Various members of the family are important in agriculture, where they accumulate in grain crops or forage grasses and adversely affect humans or animals who consume them.

The Tooth Profile Modification in Gear Manufacture
Applied Mechanics and Materials, 2007The gear design always be focus on analyzing the static performance (strength, stress, friction) and dynamic performance (inertia, noise, vibration), and especially for dynamic, the noise and vibration of gear are big problems. Actually, the main reason of noise and vibration is transmission error between master and slave gears, but the error must ...

Modification of plasma-etched profiles by sputtering
IEEE Transactions on Plasma Science, 1999Two-dimensional etch profiles are modeled for plasma etching. The etch rate dependence on the angle of incidence of the bombarding ions on the etched surface has a sputtering-type yield. The etch profile is advanced in time by an evolution equation for an etch rate proportional to the modified ion energy flux. Approximate analytical expressions for the

A Amphoteric Copolymer Profile Modification Agent
Proceedings of SPE International Symposium on Oilfield Chemistry, 1995ABSTRACT This report provides a new gel profile modification agent prepared by a amphoteric copolymer (FT—213) and a nevol crosslinking agent (BY), and introduces the preparations of the amphoteric polymer, the crosslinking agent and the profile modification agent, the action mechanism, the conditions testing and the evaluations of the ...

Modeling of Profile Modification by Induced Precipitation
Proceedings of SPE International Symposium on Oilfield Chemistry, 1999AbstractThis paper presents a comprehensive two-phase, multi-species mathematical model for selective plugging of highly watered-out zones by induced precipitation. The approach considers the porous medium as having two regions (macropores and micropores) with different permeabilities. Two sets of coupled equations, one set for each region, are derived

Profile Modification of a Slowly Permeable Soil
Soil Science Society of America Journal, 1969Abstract Under limited water (preplant irrigation only), profile modification of Pullman silty clay loam to depths of 90 and 150 cm increased grain sorghum ( Sorghum vulgare , Pers.) yields by 66.2 and 80.1%, respectively, over a 3‐year period.

Model of resonance absorption with profile modification
The Physics of Fluids, 1982A capacitor model for resonance absorption in a weakly driven, convective regime is presented. The steepening of the plasma density profile and the amplitude of the resonantly generated wave are self-consistently determined.
