Magnetic abrasive machining is a surface finishing technique in which a magnetic field is used to force abrasive particles against the target surface. As such, finishing of conventionally inaccessible surfaces (e.g., the inside surface of a long curved pipe) is possible. The aim of this paper is to study maximum efficiency in terms of material removal rate with respect to magnetic flux density ...

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...

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...

Introduction Four generic types of construction robots have been suggested in [4]. They were an assembling robot, an interior finishing robot, an exterior wall finishing robot, and a horizontal floor finishing robot. The interior finishing robot, as explained there, was designated to execute various interior finishing operations, such as partition erection, painting, plastering, jointing, tapin...

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...

We compared the efficacies of liposomal amphotericin B (LAmB) and an amphotericin B lipid complex (ABLC) in diabetic ketoacidotic (DKA) or neutropenic mice with disseminated zygomycosis. ABLC was as effective as LAmB in neutropenic but not DKA mice. Low-dose ABLC was less effective than LAmB at reducing brain fungal burdens in both models.

Granulocyte-macrophage colony-stimulating factor enhanced the efficacy of liposomal amphotericin B (LAMB) in a murine model of disseminated infection by Rhizopus oryzae, significantly prolonging survival and reducing tissue burden. The use of gamma interferon (IFN-gamma) alone was ineffective, and IFN-gamma combined with LAMB did not improve the results obtained with LAMB alone.
