The ingestion of petroleum products by children is not infrequent. Some of the more common substances encountered are, benzene, kerosene, gasolene, and insect sprays. Kerosene is the most common poison taken by chi1dren.l The ensuing irritant and toxic manifestations have been thoroughly described by previous However, it is noteworthy that in the clinic, as well as in the literature, most of th...

in today’s turbulent world, the continuity of criticalactivities in the event of disruptions, and also fast recovery and return tobusiness as usual, are vital for sustainable success of companies. maintainingcontinuous delivery of critical business processes in the event of disruptions isa matter of business continuity. business continuity management system (bcms)is concerned with the developme...

The purpose of this study was to systematically examine the psychometric properties of the 14-item Resilience Scale (RS-14; Wagnild, 2009a). Exploratory and confirmatory factor-analytic methods were employed, including an analysis of measurement invariance models by sex and race/ethnicity. Descriptive statistics, reliability, and validity data were also calculated. Analyses were based on 2 samp...

An Agilent Simulated Distillation (SIMDIS) system is described for quality control and monitoring of refinery processes. The system uses an Agilent 6890N gas chromatograph (GC) equipped with a programmable temperature vaporizer (PTV) inlet designed specifically for high temperature analysis. A simulated distillation software program that couples with the Agilent GC ChemStation provides an easy-...

Characterization of petroleum-derived products is an area of continuing importance in environmental science, mainly related to fuel spills. In this study, a non-separative analytical method based on E-Nose (Electronic Nose) is presented as a rapid alternative for the characterization of several different petroleum-derived products including gasoline, diesel, aromatic solvents, and ethanol sampl...

In this paper, we continue addressing the multi-region distribution problem of petroleum products in large quantities involving the use of a fleet of tankers parked in depots. This heterogeneous fleet consists of vehicles owned by the company or of renting, non-compartmentalized and without volumeters, to serve customers from removal sites. The objective is to minimize transportation cost while...

In order to reduce the wastage and loss of petroleum products in transit, a monitoring and management system is proposed for tank truck transportation. In this system, a vehicle transport recorder is developed to record the operations of inputs and outputs of a tank truck via a kind of Hall Effect switch sensors. Wireless data transceivers are designed to start and stop monitoring in the starti...

Real-time viscosity measurement remains a necessity for highly automated industry. The off-line viscosity measuring destroys the real time performance and the precision, and the change of temperature causes a biggish impact to the output. Density is one of the most universal and easily measurable qualitative characteristics of petroleum products. Knowledge of this quantity enables one not only ...

the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...
