BACKGROUND The objective of this study was to assess the agreement and repeatability of 2 methods of measuring habitual coffee consumption, and to examine their homogeneity with respect to socioeconomic and lifestyle factors. METHODS Data on coffee consumption were collected from 4254 subjects by means of a health questionnaire (HQ) and a 1-year dietary history interview (DHI), the latter of ...

The call center managers at Hydro-Québec (HQ) need to deliver both low operating costs and high service quality. Their task is especially difficult because they need to handle a large workforce (more than 500 employees) while satisfying an incoming demand that is typically both time-varying and uncertain. The current techniques for determining the schedule of each employee according to the fore...

Measurements of DSC, NMR and high-frequency spectroscopy have been done on PEO-H2O and PEO-H2O-HQ mixed systems. DSC measurements show that water molecules contained in PEO are divided roughly into two species: freezable water and non-freezable water. By 1H-NMR measurements, PEO and H2O protons show an absorption peak around 3.6 ppm and 4.5 ppm, respectively. All the PEO-H2O samples containing ...

As it is known, Yang-Mills gauge theories have highly degenerated vacuum structure on the classical level [1]. Quantum tunnelling transitions between different vacuum states are associated with instantons [2]. Experimental search of the QCD-instantons goes already at HERA (DESY, Hamburg) in electron-proton deep inelastic scattering [3]. There are following theoretically predicted features of in...

A 2-chloro-4-nitrophenol (2C4NP) degrading bacterial strain designated as RKJ 800 was isolated from a pesticide contaminated site of India by enrichment method and utilized 2C4NP as sole source of carbon and energy. The stoichiometric amounts of nitrite and chloride ions were detected during the degradation of 2C4NP. On the basis of thin layer chromatography, high performance liquid chromatogra...

Catalysis of the hydrolysis organ phosphorus compound, quinalphos (Q) by (hydr) oxides was studied at pH 4.0, 7.0, and 10.0, 25oC. FeOOH Al(OH)3 were used solids for this research. followed determining disappearance Q appearance 2-hydroxyquinoxaline (HQ) product in absence presence using HPLC with UV detector. Under these conditions, both hydroxides (FeOOH Al(OH)3) have catalyzed quinalphos. In...
