Incorporating numerical molecular characterization into pseudo-component representation of light to middle petroleum distillates

Short-term biomarkers of tumor promotion in mouse skin treated with petroleum middle distillates.

Topical application of certain petroleum middle distillates (PMD) to mice produces skin tumors after long latency, and initiation/promotion protocols indicate that this effect is associated with their tumor promoting activity. Since induction of sustained, potentiated epidermal hyperplasia is predictive of promoting activity, five compositionally distinct PMD [hydrodesulfurized kerosene (API 81...

Molecular Programming Pseudo-code Representation to Molecular Electronics

This research paper is proposing the idea of pseudo code representation to molecular programming used in designing molecular electronics devices. Already the schematic representation of logical gates like AND, OR, NOT etc.from molecular diodes or resonant tunneling diode are available. This paper is setting a generic pseudo code model so that various logic gates can be formulated. These molecul...

A comprehensive evaluation of the mechanism of skin tumorigenesis by straight-run and cracked petroleum middle distillates.

The role of skin irritation and other factors on the tumorigenic activity of petroleum middle distillates (PMDs) in mice was examined in a comprehensive research program. The program culminated in a 2-year dermal carcinogenicity study which compared the effects of equal weekly doses of irritating and nonirritating PMDs. Modified Ames mutagenicity studies and three- to seven-ring polycyclic arom...

Characterisation of middle-distillates by comprehensive two-dimensional gas chromatography (GC x GC): A powerful alternative for performing various standard analysis of middle-distillates.

The detailed characterisation of middle distillates is essential for a better understanding of reactions involved in refining process. Owing to higher resolution power and enhanced sensitivity, comprehensive two-dimensional gas chromatography (GC x GC) is a powerful tool for improving characterisation of petroleum samples. The aim of this paper is to compare GC x GC and various ASTM methods -- ...
