Distortion product otoacoustic emission (DPOAE) levels in response to primary pairs (f2 = 2 or 4 kHz, L2 ranging from 20 to 60 dB SPL, L1 = 0.4L2 + 39 dB) were measured with and without suppressor tones (f3), which varied from 1 octave below to 1/2 octave above f2, in normal-hearing subjects. Suppressor level (L3) varied from -5 to 85 dB SPL. DPOAE levels were converted into decrements by subtr...
This paper reports on two listening experiments which explore the relative contributions of F2 and F3 in the perception of rhoticity. Experiment 1 tests the hypothesis that a low-frequency F3 is a crucial spectral component for a signal to be perceived as rhotic. Its results suggest that the removal of F3 may in fact strengthen the rhoticity percept. Experiment 2 manipulates the relative amplit...
OBJECTIVE The aim of this study was to investigate liver fibrosis using non-invasive Real-time Tissue Elastography (RTE) and transient elastography (FibroScan) methods. METHODS RTE, FibroScan and percutaneous liver biopsy were all performed on patients with chronic liver disease, particularly hepatitis C, to investigate liver fibrosis. RESULTS FibroScan and RTE were compared for fibrous liv...
Heterosis effects for birth weight, ADG from birth to weaning, 200-d weight, ADG from weaning to 368 d, 368-d weight, 368-d height, 368-d condition score, and 368-d muscling score (males only) were evaluated separately for each sex in F1, F2, and combined F3 and F4 generations in three composite beef cattle populations. Breed effects were evaluated for the nine parental breeds (i.e., Red Poll [...
Let F be an n-uniform hypergraph on 2n vertices. Suppose that |F1∩F2∩F3∩F4| ≥ 2 and |F1∪F2∪F3∪ F4| ≤ n−2 holds for all F1,F2,F3,F4 ∈F . We prove that the size of F is at most (2n−4 n−2 ) for n sufficiently large.

breeding programs strategies depends on genetical mechanism of selection traits. in the present research, generation mean analysis with joint scaling test was performed to determine the gene action. f1, f2 and f3 generations, derived from roushan and kavir cross along with their parents were sown in a partial lattice design with two replications under stress condition at the research field of s...
