Safflower (Carthamus tinctoius L.) is an Iranian native crop that is adapted to different environmental conditions of this country. Sixteen safflower varieties/lines were spring-planted in 6 research stations including Sararood (Kermanshah), Maragheh, Ghamlo (Kordestan), Khodabandeh (Zanjan), Shirvan (North Khorasan)and Khohdasht (Lorestan) with and without drought stress conditions each in a R...
OBJECTIVE To understand gender differences in sexual behaviours in response to genitourinary symptoms. METHODS 473 (239 female and 234 male) subjects were enrolled at an STD clinic regardless of symptoms or infection status. Subjects completed a 30 day calendar recall interview of genitourinary symptoms, coital activity, sexual partners, and condom use. RESULTS Of the total of 473 participa...
OBJECTIVES To evaluate parental attitudes about adolescent vaccination as a function of vaccine characteristics, including whether the vaccine prevented a sexually transmitted infection (STI), and to explore possible sociodemographic predictors of acceptability of STI vaccines. DESIGN Participants were 278 parents who accompanied their children (69.1% female, aged 12-17 years) to appointments...
Two are the goals of the work presented in this paper. The first one is the implementation of a new method of speech enhancement using microphone arrays. This method gets noise reduction of speech signal using the masking properties of the human auditory system. The second goal of the paper is to use RASTI index (RApid Speech Transmission Index) for objective evaluation of speech signal quality...
We propose a Non-Intrusive (or reference-free) Audio Clarity index (NIAC), inspired from previous works on image sharpness and defined as the sensitivity of spectrogram sparsity to convolution audio signal with white noise. A closed-form formula is provided, which only involves itself very little parameter setting. Tested in various noise reverberation conditions, NIAC exhibits high correlation...
Indirect systolic time intervals (STI) corrected for heart rate were compared at rest and immediately following 3 minutes of moderate supine exercise in 33 normal subjects and 32 ageand sex-matched patients with coronary artery disease (CAD). The intervals were correlated with measurements of cardiac index (Cl), stroke volume index (SVI), mean pulmonary artery aind wedge pressures obtained unde...
