the effects of dietary inclusion of medicinal plants’ by-product mixture on performance, the relative internal organ weight, ileal microbial counts, and small intestinal and liver morphologic alterations in laying hens receiving different omega-6 to omega-3 ratios as a 2×3 factorial arrangements with three levels of plants’ by-product (zero, 2.5 and five percent) and two omega-6 to omega-3 rati...

conclusions the outside diameter/inside diameter ratio at the metaphyseal/diaphyseal junction of the distal radius on ap radiographs is suitable for use as a predictor of distal-radius bone density. further studies should be performed, and clinical utility evaluated. results the mean bmd was 0.559 (sd = 0.236) g / cm2. the mean outside diameter/inside diameter ratio was 1.24 (sd = 0.013); the r...

Models of the perceived distance between pairs of pitch collections are a core component of broader models of the perception of tonality as a whole. Numerous different distance measures have been proposed, including voice-leading, psychoacoustic, and pitch and interval class distances; but, so far, there has been no attempt to bind these different measures into a single mathematical framework, ...

background : a head and neck (h&n;) cancer severely affect the voice and compromises the patient’s vocal independence. the present study proposed to investigate the difference in the three vital components of voice the pitch, jitter and shimmer in h&n; cancer patients and compared it with age matched healthy volunteers. methods : the voice parameters were ascertained in the freshly diagnosed h&...

The pitches produced by toy pianos are sometimes perceived to be inaccurate by listeners, some of whom report perceiving the perfect fifth above the nominal note of the pressed key. To investigate these assertions, the overtone frequencies of a toy piano were measured in a frequency range of no more than the eighth harmonic and below 5 kHz, which are considered to be important to the pitch perc...

The simplest aerodynamic model of horizontal-axis wind turbines is the blade element momentum theory, which assumes that blades behave as airfoils, but a correct two-dimensional representation an infinite cascade lifting bodies. This study analyzes conventional and impulse forms forces on cascades airfoils at spacings pitch angles typical turbine applications. OpenFOAM software was used to simu...

OBJECTIVE The aim of this study was to investigate physiological changes in cardiac area and diameters between inspiratory and expiratory chest computed tomography (CT), and to assess their correlation with lung size change and influence on cardiothoracic ratio (CTR) measurements. MATERIALS AND METHODS The institutional review board of our institution approved this study, and informed consent...

two separate experiments were carried out with the aim of investigating the effect of vermicompost and its aqueous extracts on traits related to germination and growth of tomato varieties, (mobil and superorbina). in the first experiment, 0.5, 1, 1.5, 2, 2.5, 5, 7.5, 10 and 100% extracts of vermicompost (v - v) along with control (distilled water) were studied on germination of two varieties of...

1. The temporal discharge patterns of auditory nerve fibers in Dial-anesthetized cats were studied in response to periodic complex acoustic waveforms that evoke pitches at their fundamental frequencies. Single-formant vowels, amplitude-modulated (AM) and quasi-frequency-modulated tones. AM noise, click trains, and other complex tones were utilized. Distributions of intervals between successive ...

a large number of authors have studied to find out how to control scouring around a pier along direct stream. the objective of this research is then to study a scour pattern around such piers on curves rivers due to the fact that there may be a difference between a flow pattern on a direct line and the meander. thus, this study tries to check whether the use of cable and collar alone and in a c...
