We collect multi-wavelength measurements of the nuclear emission of 20 low luminosity FR I radio-galaxies to test the viability of the FR I-BL Lac unifying model. Although poorly sampled, the Spectral Energy Distributions (SED) of FR Is are consistent with the double peaked shape characteristic of BL Lacs. Furthermore while the distribution of the FR Is in the broad-band spectral index planes s...

In this study, short-time Fourier transform (STFT) and wavelet transform (WT) were used for spectral analysis of ophthalmic arterial Doppler signals. Using these spectral analysis methods, the variations in the shape of the Doppler spectra as a function of time were presented in the form of sonograms in order to obtain medical information. These sonograms were then used to compare the applied m...

AIMS Left ventricular diastolic dysfunction has been proposed as the basis of heart failure in patients with normal left ventricular systolic function. Doppler indices of mitral inflow have been widely used to diagnose this condition and have been shown to correlate well with increased left atrial pressure in patients with cardiovascular disease. We wanted to establish age-specific criteria for...

BACKGROUND Alterations in waveforms in the uterine artery are associated with the development of pre-eclampsia and intrauterine growth restriction. We investigated the predictive accuracy of all uterine artery Doppler indices for both conditions in the first and second trimesters. METHODS We identified relevant studies through searches of MEDLINE, EMBASE, the Cochrane Library and Medion datab...

INTRODUCTION AND OBJECTIVES To evaluate ventricular function using Doppler echocardiography in patients with an atrial septal defect (ASD). METHODS The study involved 158 children, who were divided into two groups: Group 1 comprised 111 children with an ASD, and Group 2, 47 healthy children. Left ventricular systolic function was evaluated by measuring the ejection fraction, the shortening fr...

BACKGROUND Pulsed wave (PW) Doppler echocardiography has become a routine non invasive cardiac diagnostic tool in most species. However, evaluation of intracardiac blood flow requires reference values, which are poorly documented in goats. The aim of this study was to test the repeatability, the variability, and to establish the reference values of PW measurements in healthy adult Saanen goats....

OBJECTIVE To evaluate the behavior of LV diastolic displacement velocities of basal posterior septum near mitral ring segment obtained by tissue Doppler in relation to mitral flow velocities of hypertensive subjects, submitted to preload increase by left inferior limbs elevation for 5 minutes, and during 1 minute of handgrip (conditions 1 and 2, respectively). METHODS Twenty five outpatients ...

Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...

background: carpal tunnel syndrome (ctu) is the most common neuropathy in the body and one of the most important causes of occupational disability. the aim of the present study was to compare the diagnostic power of doppler sonography and gray scale in diagnosing cts and their comparison with nerve conduction studies (ncv). methods: in this analytical study, diagnostic value of doppler and gray...
