micro gravity data was collected in a crowded street in tehran where a subway terrain tunnel is to be excavated. the data is corrected for the gravity effects of the surrounding densely built up area with diverse buildings and the bouguer gravity anomalies are computed. the residual gravity anomalies are prepared by removing a trend surface. upward continuation is used to remove the gravity eff...

OBJECTIVE The aim of this study in pregnant women with hypothyroidism treated by levothyroxine is to examine the interrelations between thyroid-stimulating hormone (TSH), free thyroxine (FT(4)) and free tri-iodothyronine (FT(3)), and examine whether in such patients the treatment is adequate. METHODS This was a retrospective cross-sectional study. Maternal serum concentrations of FT(3), FT(4)...

PURPOSE To compare reduced colonic cleansing based on dietary fecal tagging (FT) with standard (non-FT) colonic cleansing with regard to patient acceptance, sensitivity, and specificity. MATERIALS AND METHODS In 50 patients (FT group), FT was performed by means of diet, magnesium citrate, and a barium suspension. In another 50 patients (non-FT group), preparation was based on polyethylene gly...

BACKGROUND The growing interest in measuring blood free testosterone (FT) is constrained by the unsuitability of the laborious reference methods for wider adoption in routine diagnostic laboratories. Various alternative derived testosterone measures have been proposed to estimate FT from either additional assay steps or calculations using total testosterone (TT) and sex hormone-binding globulin...

In this note we prove the backwards uniqueness of the mean curvature flow in codimension one case. More precisely,let Ft, e Ft : M → M n+1 be two complete solutions of the mean curvature flow on M×[0, T ] with bounded second fundamental form in a complete ambient manifold with bounded geometry. Suppose FT = e FT , then Ft = e Ft on M n × [0, T ]. This is an analog of a recent result of Kotschwa...
