fluoride is an essential element for human health. however, excess fluoride in drinking water may cause dental and/or skeletal fluorosis. drinking water is the main route of fluoride intake. the aim of the present study was to measure fluoride levels in human breast milk collected from two regions of golestan province, northern iran with different amount of fluoride concentration of drinking wa...

Jiang, S., Barber, E.M., Meiering, A.G. and Jofriet, J.C. 1991. Toxic gas production and silo ventilation. Can. Agric. Eng. 33:151-159. Equations were developed to predict the minimum safe duration of ventilationrequired in tower silos to reduce carbon dioxide and oxides of nitrogen to safe limits for human entry into the silo. Unlike previous analyses, the model developed in this paper account...

The desire to procreate in patients living with HIV (PLHIV) has been seldom investigated in Africa, particularly in Gabon. The aim of this transversal and descriptive study was to analyze the socio-demographic and behavioral factors associated with a desire to have children in a cohort of PLHIV. The study included 442 patients, predominantly females [79.9% (337/422)], and those with a secondary...

A unitary quantum gas is a gas of quantum particles with a binary interaction of infinite scattering length and negligible range. It has been produced in recent experiments with gases of fermionic atoms by means of a Feshbach resonance. Using the Fermi pseudo-potential model for the atomic interaction, we show that the time evolution of such a gas in an isotropic three-dimensional time dependen...

The aim of this study was to determine the potential application of N-chlorotaurine (NCT), N,N-dichloro-2,2-dimethyltaurine (NVC-422), and N-monochloro-2,2-dimethyltaurine (NVC-612) as catheter lock solutions for the prevention of catheter blockage and catheter-related bloodstream infections by testing their anticoagulant and broad-spectrum antimicrobial activities in human blood. NCT, NVC-422,...
