The effect of soybean meal, feather meal and hair meal on dry matter (DM), energy and nitrogen (N) utilization by growing steers was evaluated in three metabolism studies. Feather meal (FM) and hair meal (HM) protein were substituted for 25, 50 and 75% (Exp. 1, 2 and 3, respectively) of the soybean meal (SBM) protein in pelleted protein supplements and fed in whole-shelled, corn-ground corncob ...

Partial stage and complete life-cycle growth curves of Brahman cattle were obtained for small, medium, and large frame sizes for a herd under grazing conditions in a subtropical environment. Data were grouped into three stages: birth to weaning (stage 1), weaning to 20 mo (males) or 32 mo (females) of age (stage 2), and 32 mo of age to maturity (females only; stage 3). Within each stage, multip...

We define the problem “identity check”: Given a classical description of a quantum circuit, determine whether it is almost equivalent to the identity. Explicitly, the task is to decide whether the corresponding unitary is close to a complex multiple of the identity matrix with respect to the operator norm. We show that this problem is QMA-complete. A generalization of this problem is “equivalen...

Uma das etapas do tratamento endodôntico é a instrumentação dos canais, utilizando as limas endodônticas. As Limas M (Easy) foram desenvolvidas recentemente visando preparos efetivos e seguros. Este estudo avaliou o poder de corte resistência à fratura após aplicação diferentes protocolos em canais radiculares artificiais. O primeiro protocolo (Grupo 1) instrumentos diâmetro ponta 15 40, com co...

If physics at the Planck scale requires new conceptions of spacetime, then generic renormalizable field theories predict observable violations of Lorentz invariance in the low energy sector. The little recognized “Lorentz Fine Tuning Problem” comes from logarithmic loop corrections which are not suppressed to the enormous extent commonly assumed. Fine-tuning of parameters at the Planck scale is...
