Background. The implications of hypotension occurring during dobutamine stress echocardiography have not been elucidated. We observed in some patients that hyperdynamic left ventricular function developed during dobutamine stress echocardiography and hypothesized that intracavitary obstruction was occurring and might account for hypotension in some patients. Methods and Results. Fifty-seven con...

A 2d numerical study has been conducted by using Ansys Fluent 2020R2 program to design 4 different cases(shapes) for buildings at a initial velocity value (2,4,6 m/sec) .in order find way benefit from the areas where winds is small and it not enough operate turbines. Where analysis carried out four cases, each of them separately, intensity turbulence pressure around calculated. The highest obta...

Selenocysteine (Sec)-decoding archaea and eukaryotes employ a unique route of Sec-tRNA(Sec) synthesis in which O-phosphoseryl-tRNA(Sec) kinase (PSTK) phosphorylates Ser-tRNA(Sec) to produce the O-phosphoseryl-tRNA(Sec) (Sep-tRNA(Sec)) substrate that Sep-tRNA:Sec-tRNA synthase (SepSecS) converts to Sec-tRNA(Sec). This study presents a biochemical characterization of Methanocaldococcus jannaschii...

Lechtman, M. D. (University of Southern California, Los Angeles), J. W. Bartholomew, A. Phillips, and M. Russo. Rapid methods of staining bacterial spores at room temperature. J. Bacteriol. 89:848-854. 1965.-Spores of Bacillus subtilis var. niger were stained in 2 min at room temperature, after suitable pretreatment, with a dye reagent composed of 2% crystal violet in 1% phenol and 26% ethanol....

Empirical green’s function (EGF) analysis has remained little used to image the rupture properties of the giant 26 December 2004 Sumatra earthquake. The 2 November 2002 foreshock (Mw 7.2), close to the mainshock epicenter, gives us the opportunity to use its waveforms to empirically simulate the Rayleigh-wave propagation of the Sumatra earthquake. We first show that the exceptional size of the ...

The whale shark (Rhincodon typus) is a wide-ranging, filter-feeding species typically observed at or near the surface. This shark's sub-surface habits and behaviors have only begun to be revealed in recent years through the use of archival and satellite tagging technology. We attached pop-up satellite archival transmitting tags to 35 whale sharks in the southeastern Gulf of Mexico off the Yucat...

A cervical carcinoma allograft model was designed to assess the correlation between early changes in the apparent diffusion coefficient (ADC) values on diffusion-weighted magnetic resonance imaging (DW-MRI) and the expression of matrix metalloproteinase-9 (MMP-9) in tumors. BALB/c mice with U14 tumor allografts on the right rear flank were irradiated with a single 20 Gy dose. All tumor-bearing ...

In this paper, stator resistance and speed estimation for a vector controlled induction motor drive taking saturation into account is presented. A mathematical dynamic model of an induction motor as influenced by magnetic circuit saturation is presented. Moreover, a modified structure of indirect vector controller scheme is proposed which involves the saturated value of the magnetizing inductan...

The potential of Near Infrared Reflectance Spectroscopy (NIRS) as a fast method to predict the Crude Protein (CP) and Moisture (M) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on Partial Least Squares (PLS) was evaluated. The coefficient of determination in calibration (R2C) and Standard Error of Calibra...

Abstract Porang is well known with its high glucomannan content. Determination of the chemical content porang flour commonly carried out by methods in laboratory, which are to take a long time and expensive. This study aims determine using near infrared spectroscopy (NIRS). The reflectance was measured an FT NIR spectrometer at wavelength 1000 2500 nm. (water content) determined oven spectropho...
