Mineral requirements for weight gain in growing male Santa Inês and Morada Nova hair sheep.

This study estimated the net macro and micromineral requirement from the 48 male uncastrated lambs (24 growing male Santa Inês and 24 growing male Morada Nova hair sheep), with initial weights of 21.7 ± 1.2 kg and 20.

Translation Hypersurfaces with Constant Sr Curvature in the Euclidean Space.

The main goal of this paper is to present a complete description of all translation hypersurfaces with constant r -curvature S r , in the Euclidean space ℝ n + 1 , where 3 ≤ r ≤ n - 1 .

How mechanical stresses modulate enamel demineralization in non-carious cervical lesions?

Objective: To introduce an experimental non-carious cervical lesion (NCCL) model for studying the influence of presence and type of stress (tension or compression) on acid effects involved in NCCL formation on the enamel near the cement-enamel junction (CEJ).

Methods: 108 bovine incisors were cut into 18 × 3×3 mm beams, with a notch in the cervical region to generate a standardized area of stress concentration. Half of the specimens were immersed in distilled water and the other half in acetic acid solution (pH 4.
