Drosophila sechellia is a species of fruit fly endemic to the Seychelles islands. Unlike its generalist sister species, D. sechellia has evolved to be a specialist on the host plant Morinda citrifolia. This specialization is interesting because the plant's fruit contains secondary defence compounds, primarily octanoic acid (OA), that are lethal to most other Drosophilids. Although ecological an...

It is generally recognized that the pathways of fatty acid breakdown and of glucose catabolism (Embden-Meyerhof scheme) are confluent at the level of the 2-carbon fragment (acetyl-S-CoA). Nevertheless, several observations suggest an interplay between the metabolism of carbohydrate and that of fatty acids at a higher level: (a) Rats forcibly fed carbohydrate, as opposed to those fasted, exhibit...

Mild steel is used as main raw material in fabrication of equipment, chief material of construction and as weapons. During the storage and transportation conditions, it comes in contact with aggressive environment which leads to decrease in mechanical strength. Four different vapor phase corrosion inhibitors (VPCIs) i.e. n-Caprylic acid (CA), nButyric acid (BA), N,N-dimethyl propylene urea (DMP...

With use of a conditioning paradigm, the ability of four squirrel monkeys to distinguish n-valeric acid from n-forms and isoforms of other carboxylic acids (acetic acid to octanoic acid) was investigated. All four animals were clearly able to discriminate between all odor pairs tested and showed a significant negative correlation between discrimination performance and structural similarity of o...

The synergistic influences of three unsaturated fatty acids (UFAs, namely linoleic acid, oleic acid and linolenic acid) on the fatty acid composition of Saccharomyces cerevisiae and major volatile compounds were investigated in synthetic grape juice. The addition of UFAs led to a corresponding increase in UFAs in the cellular lipid, which was accompanied by a reverse reduction in the content of...

Dyes are pollutants widely used in several industries that end up dumped as wastewater, contributing to water pollution. In the scope of improving quality, liquid-liquid extraction is a separation technique remove from water, due possibility recovering all involved agents. this work, deep eutectic solvents (DESs) based on mixtures thymol with menthol, coumarin, octanoic acid and decanoic were a...

The material described in this article deals with waste conversion into energy vectors by pyrolysis, steam cracking, or oxidation of liquid biomass, carried out at small to medium scale. design a bench-scale experimental setup devoted gas phase kinetic data generation tubular reactor under laminar regime close plug flow is detailed based on very simple approach. Validation the designed was succ...

The volatilomic fingerprint of nine different whiskeys was established using a rapid and sensitive analytical approach based on dispersive liquid–liquid microextraction (DLL?E) followed by gas chromatography mass spectrometry detection (GC-MS) with flame ionization (GC-FID). influence the extractor solvent extraction efficiency volatile compounds (VOCs) evaluated DLL?E/GC-MS. highest amounts VO...
