The number of lambs sold per ewe mated in the breeding flock has a considerable impact on sheep operation profitability. This depends primarily on fertility, prolificacy (# of lambs), and lamb survival, mothering ability, milk production of the ewe and lamb growth rate. Optimal reproduction does vary by environment and management system – some sheep operations don’t want a lambing rate over 200...

ptinidae or spider beetles, is a worldwide family of beetles especially distributed in the subtropical and temperate zones including iran. niptus holoeucus (golden spider beetle) from kangohar cave in fars province (iran) is described as new record for iran. we regarded this beetle as a troglophile and guanophile species.

Georgia is on the southeastern margin of the native range of the brown recluse spider, Loxosceles reclusa Gertsch and Mulaik. The brown recluse is not a common Georgia spider and has limited distribution in the state. Using recent submissions, previously published records, and examination of museum specimens, we document the spiderÕs presence in 31 (19.5%) of GeorgiaÕs 159 counties, with almost...

We present the calculation of Next-to-Leading-Order Quantum Chromo Dynamics corrections for the production of a W or Z weak boson associated with a bottom anti-bottom quark pair at hadron colliders (pp̄, pp → W/Z bb̄), including the effects of a non-zero bottomquark mass. We find a considerable reduction of the renormalization and factorization scale dependence of our results with respect to Lead...

a study was conducted to evaluate effects of age at weaning on various growth characteristics and stress measures of zandi lambs. the lambs were weaned at 45 and 90 days of age. the body weights and average daily gain (adg) were monitored during the experimental period and 5 months of age. cortisol, glucose, blood urea nitrogen (bun) and lamb behavior (agitation, vocalization) were recorded bef...

This paper examines the environmental and management factors affecting lamb survival on high-performing sheep farms in New Zealand. Improved lambing percentage is the biggest contributor to higher profits on New Zealand sheep farms. Many sheep breeders have selected and bred ewes for increased fecundity over the last 4 decades. The increased proportion of ewes having triplets is of concern to f...

Matching pursuit (MP) is an adaptive signal decomposition technique and can be applied to process Lamb waves, such as denoising, wave parameter estimation, and feature extraction, for health monitoring applications. This paper explored matching pursuit decomposition using Gaussian and chirplet dictionaries to decompose/approximate Lamb waves and extract wave parameters. While Gaussian dictionar...

The survival probability, SN(t), of a diffusing prey (‘lamb’) in the proximity of N diffusing predators (a ‘pride of lions’) in one dimension is investigated. When the lions are all to one side of the lamb, the survival probability decays as a non-universal power law, SN(t) ∝ t−βN , with the decay exponent βN proportional to ln N . The crossover behaviour as a function of the relative diffusivi...

Bacteriophage lambda adsorbs to its Escherichia coli K-12 host by interacting with LamB, its cell-surface receptor. We fused C-terminal portions of J, the tail fiber protein of lambda, to maltose-binding protein. Solid-phase binding assays demonstrated that a purified fusion protein comprising only the last 249 residues of J could bind to LamB trimers and inhibited recognition by anti-LamB anti...
