to determine the effect of hen age and storage condition on egg quality, fresh eggs were sampled from two commercial flocks of white leghorn hens at 28 and 68 weeks of age. half of sampled eggs from each flock were stored at 6°c and the other half was stored at room temperature. fifteen eggs were randomly sampled from each treatment following collection and at 5-day intervals to 30 days of stor...

In the tritone paradox, two tones are presented that are related by a half-octave. Each tone consists of a set of octave-related sinusoids whose amplitudes are scaled by a bell-shaped spectral envelope; thus the usual cues to height attribution are missing. When listeners judge whether such tone pairs form ascending or descending patterns, judgments are related in an orderly fashion to the posi...

To determine whether simulated microgravity in rats is associated with vascular dysfunction, we measured responses of isolated, pressurized mesenteric resistance artery segments (157- to 388-microm ID) to vasoconstrictors, pressure, and shear stress after 28-day hindlimb suspension (HS). Results indicated no differences between HS and control (C) groups in 1) sensitivity or maximal responses to...

The sphingolipid signaling pathway appears to play an important role in regulating vascular tone. We examined the effect of fumonisin B(1), a fungal toxin in corn that blocks ceramide synthase in the sphingolipid signaling pathway, on the ascending aortic impedance spectrum of pigs. Sixteen pigs were fed culture material containing fumonisin B(1) (20 mg/kg body wt) (n = 7) or a control diet (n ...

This paper presents the comparative study of different crest factor reduction techniques such as Clipping, Block coding, Partial Transmit Sequences (PTS), Tone Reservation (TR) and Tone Injection, Selective Mapping, Interleaving, Active Constellation Extension (ACE) and Peak Windowing, clipping has been identified as the best technique for Peak-to-Average Power Ratio reduction as it does not re...

We report on the generation and transmission of a millimeter-wave (MMW) signal with frequency 28 GHz by employing an InAs/InP quantum-dash dual-wavelength laser diode (QD-DWL) emitting in ~1610 nm extended L-band window. The self-injection locking (SIL) technique has been engaged to improve linewidth reduce noise optical tone. Besides, 2 Gbits/s quadrature phase-shift keying (QPSK)-modulated 28...

The purpose of this study was to describe the relationship between sequential stream segregation abilities of listeners with hearing loss and the ability to recognize pairs of sentences spoken simultaneously by a man and a woman. In the streaming task, the fusion threshold was measured as the frequency separation at which listeners could no longer perceptually separate a series of fixed and var...

Language experience is known to modulate the preattentive processing of linguistically relevant pitch contours when presented in the speech domain. To assess if experience-dependent effects are specific to speech, we evaluated the mismatch negativity response to nonspeech homologs (iterated rippled noise) of such curvilinear pitch contours (Mandarin: Tone 1, 'high level'; Tone 2, 'high rising')...
