A dynamic and prospective model to predict and prevent errors in production processes

In the industrial production field, a highly competitive sector, companies are increasingly facing complex decisionmaking problems that require the use of effective decision support tools. In this research area, multi-criteria decisionmaking (MCDM) methods are particularly useful as an effective tool to support decision makers (DMs) in critical decisionmaking processes ([1]). Our approach aims to propose the integration of a dynamic and prospective technique, already proposed in the l...

Threat of Amphetamine type stimulants (ATS) for the society of Pakistan: analysis based on seizure data and seized illicit drug materials

Background: Amphetamine type stimulants (ATS) is a group of illicit drugs that produce a sense of excitement and pleasure, and due to these stimulant effects, these are called party drugs. ATS include amphetamine (AMP), methamphetamine (MET) and 3,4-methylenedioxymethamphetamine (MDMA). In Pakistan these drugs are less common if compared to hashish and heroin. However, in the last few years the abuse of these drugs has increased, most probably because they can be easily manufactured. Furtherm...

ISOMER SEPARATIONS BY INNOVATIVE GAS CHROMATOGRAPHY STATIONARY PHASES

The chromatographic separation of aromatic amines and xylenes isomers represents a big issue in chemical and petroleum industries, owing to their high similarity in terms of molecular sizes, polarity, and boiling points: as a result, commercial columns very often do not allow their complete peak separation. For this reason, several typologies of materials with different structures and properties have been developed and proposed as gas chromatography stationary phases in recent years. Macrocyc...

INNOVATIVE PILLAR[6]ARENE-BASED STATIONARY PHASES FOR HIGH-RESOLUTION GAS CHROMATOGRAPHIC ANALYSES

In this work, the synthesis, fabrication, and characterization of new stationary phases based on pillar[6]arene derivative modified by long alkyl chains (P6A-C10) for high-resolution gas chromatographic (GC) analyses are reported. Pillar[n]arenes are a new class of macrocyclic hosts that can accommodate specific guests due to their highly symmetrical and rigid pillar architectures with π-electron rich cavities. Quantum chemistry calculations have been performed, showing a difference in non-co...
