Two unselected herds of purebred Hereford and Angus cattle were created and their progeny evaluated during a 4-yr period (1964 to 1967) for 168-d postweaning gain when they were fed either a high- or medium-energy diet. Birth weight and 200-d adjusted weaning weight also were measured and the importance of sire x diet interactions for postweaning gain examined. Year effects were significant (P ...

We evaluated the effects of air-drying distance and bond surface area on the shear bond strength of a 2-step etch-and-rinse adhesive. A total of 120 bovine anterior teeth were equally divided into 6 main groups based on bonding surface area. The main groups were divided into sub-groups (n = 5) according to air-drying distance. The shear strength was determined using a universal testing machine ...

Salt preference was assessed in 60 adults of 18-21 yrs of age (30 males and 30 females) and in 60 children of 7-12 yrs of age (30 boys and 30 girls). Subjects rated the preference on Likert scale for popcorns of five salt concentrations (OM, 1M, 2M, 3M and +3M). Statistical analysis using Two way ANOVA revealed statistically significant effect of age and sex on salt preference (F4,100 = 15.027,...

This paper examines the acoustic properties of Sylheti phonemes. Sylheti is generally regarded as one of the varieties of Bangla. The historical development of this language witnessed significant reduction and reconstruction of its phoneme inventory. The phoneme inventory is considerably reduced due to the phonological process of deaspiration [+spread glottis], spirantization and deaffrication ...

In June 2006, two populations of Dactylorhiza were examined at Moses Gate Country Park, in Greater Manchester, to determine whether variation exists between the two populations. Careful measurements of orchid characteristics were taken at both sites, in addition to soil pH recordings, and the results compared and tested for significance using one-way ANOVA and Chi-square significance tests. Des...

Concentrations of various proteins in uterine flushings have been described as a direct method for assessment of the secretory activity of the endometrium. We investigated levels of the endometrial protein known as placental protein 14 (PP14) in flushings obtained from 271 infertile women. Under transvaginal ultrasonographic control, 2 ml of 0.154 M sodium chloride solution were injected into t...
