The objective of this experiment was to provide a current evaluation of the seven most prominent beef breeds in the United States and to determine the relative changes that have occurred in these breeds since they were evaluated with samples of sires born 25 to 30 yr earlier. Carcass (n = 649), yield (n = 569), and longissimus thoracis palatability (n = 569) traits from F(1) steers obtained fro...

the objective of this study was to highlight the postnatal development of the uterine tubes of the west african dwarf goat from birth to 28 weeks of age by gross examination and light microscopy. there was a caudal migration of the paired uterine tubes from behind the paired kidneys at birth to the pelvic inlet at week 8 of age. each uterine tube exhibited three segments namely; infundibulum, a...

this study was carried out to investigate the important characteristics in some cultivars/genotypes of persianwalnut (juglans regia l.), black walnut (j. nigra l.), and walnut inter-specific hybrids: paradox (j. hindsii × j.regia) and royal (j. hindsii × j. nigra) in kamalshahr research station in karaj in 2011-2012. in the study,vegetative vigor was evaluated based on trunk cross-sectional are...

The purpose of this study is to describe the histological and histochemical features of digestive tract intwo aquarium fishes with different types of feeding habits which are omnivorous (Walking catfish) andcarnivorous (piranha), respectively. Five adult Walking catfish (L: 26.4 ± 3.4 cm, W: 265 ± 55 g) and fiveadult piranha (L: 23.6 ± 4.5 cm, W: 247 ± 50 g) were used for this study. The fishes...

Nanocrystalline silicon embedded carbide, nc-Si(SiC) thin films were deposited on p-type substrates by using a thermal chemical vapor deposition (CVD) with different process temperatures from 700 to 1000 °C. The SEM images reveal the Si particles are SiC films. estimated crystallite size of was varied 14 28 nm and 40.7 61 respectively Scherrer formula Williamson – Hall formula. Similarly, latti...

A high-resolution accelerometer with a bulk-micromachined silicon proof mass and an interferometric position sensor was developed for measuring vibratory accelerations. The interferometer consists of interdigitated fingers that are alternately attached to the proof mass and support substrate. Illuminating the fingers with coherent light generates a series of diffracted beams. The intensity of a...
