Analysis of expired air of fasting male monks at Mount Athos
(2006)Expired air chemical analysis is investigated as a search and locate method for the early detection of entrapped people under the ruins of collapsed buildings after an earthquake. Fasting individuals were examined as a ...

Analytical separations in open-tubular capillary electrochromatography
(2003)This review represents a summary of recent progress in open-tubular capillary electro-chromatography (OT-CEC) for chiral and achiral separations. The OT-CEC approach is an alternative to packed-CEC that could eliminate the ...

Authenticity of the traditional Cypriot spirit "zivania" on the basis of 1H NMR spectroscopy diagnostic parameters and statistical analysis
(2005)A previous publication (Kokkinofta et al. J. Agric. Food Chem. 2003, 51, 6233-6239) discussed the use of inductively coupled plasma spectroscopy to differentiate between the traditional Cypriot alcoholic beverage zivania ...

Chemometric characterization of the cypriot spirit "Zivania"
(2005)In 42 alcoholic beverages produced in Cyprus and other countries, 26 chemical and physical-chemical variables were determined by HPLC and GC chromatography, 1H NMR and ICP spectroscopy, and other techniques. Data were ...

Chiral ionic liquids in chromatographic and electrophoretic separations
(2014)This report provides an overview of the application of chiral ionic liquids (CILs) in separation technology, and particularly in capillary electrophoresis and both gas and liquid chromatography. There is a large number of ...

Combined chemical and optical methods for monitoring the early decay stages of surrogate human models
(2011)As the body decays shortly after death, a variety of gases and volatile organic compounds (VOCs) constantly emanate. Ethical and practical reasons limit the use of human corpses in controlled, time-dependent, intervening ...

Discriminant Analysis of Volatile Organic Compounds data related to a new location method of entrapped people in collapsed buildings of an earthquake
(2006)Discriminant Analysis is used as a part of a research, which aims at using expired air analysis for the early location of entrapped people under the ruins of collapsed buildings in an earthquake. This work focuses on the ...

Environmental aspects of VOCs evolved in the early stages of human decomposition
(2007)In the present study, the time profile, measured as "accumulation", of volatile organic compounds (VOCs) produced during the early stages of human decomposition was investigated. A human cadaver was placed in a sealed bag ...

NMR and theoretical investigations on the structures and dynamics of octahedral bis(chelate)dichloro VIII compounds isolated by an unusual reduction of non-oxo VIV species
(2003)Reaction of the non-oxo VIV species [VIVCl2(LOO)2] [LOO = acetylacetonate (acac-) or benzoylacetonate (bzac-)] with a chelate nitrogen-donor ligand LNN in acetonitrile leads to the reduction of VIV to VIII and the formation ...

Regioselective hydrodehalogenation of 3,5-dihaloisothiazole-4- carbonitriles: Synthesis of 3-haloisothiazole-4-carbonitriles
(2011)3,5-Dibromoisothiazole-4-carbonitrile 1 treated with Zn or In dust (5 equiv) and HCO2H undergoes regioselective hydrodebromination to give 3-bromoisothiazole-4-carbonitrile 3 in 70-74% yield. Similarly, 5-bromo and iodo ...

A study of volatile organic compounds evolved from the decaying human body
(2005)Two men were found dead near the island of Samos, Greece, in the Mediterranean sea. The estimated time of death for both victims was 3-4 weeks. Autopsy revealed no remarkable external injuries or acute poisoning. The exact ...
