we conducted this study to determine the level of immunity after vaccination of lambs with whole bodyechinococcus granulosus. to do so, 200 mature e. granulosus parasites, which were kept in 10% formalinefor 8 months, were obtained from the department of parasitology, school of veterinary medicine, ferdowsiuniversity of mashhad. the soluble protein of the parasite was prepared. the sample was h...

the objectives of this study were to determine the effects of feeding rapeseed (27%, dm basis) and sunflower biodiesel by-products as protein supplements on fatty acid composition (fa), profile (ratios and indices),enzyme activitiesfrom thecarcassin lambs fed cereal-based diets. simultaneously, itwas examined the relationship between ingested fa and carcass fa. samples were obtaine dfrommal efa...

Lamb and mutton are the most important sources of income for South African Merino farmers. The possibility of genetically improving survival of a Merino lambs was assessed with data from 5769 lambs that were born alive in the Cradock fine wool stud from 1998 to 2003. Three traits can possibly be linked to lamb survival and can therefore be included in selection programs, namely birth coat score...

Lamb waves are dispersive in a plate and elastic properties of anisotropic materials are dependent on the crystal orientation. It is expected that the wave propagation on a thin anisotropic plate is complex due to dispersion of Lamb waves which will be dependent on the propagation direction. Therefore it is essential to understand elastic waves in an anisotropic plate. In the present work, a si...

The folding mechanisms for β-barrel membrane proteins present unique challenges because acquisition of both secondary and tertiary structure is coupled with insertion into the bilayer. For the porins in Escherichia coli outer membrane, the assembly pathway also includes association into homotrimers. We study the folding pathway for purified LamB protein in detergent and observe extreme hysteres...

In this article, ultrasonic guided wave propagation and interaction with the rivet hole cracks has been formulated using closed-form analytical solution while the local damage interaction, scattering, and mode conversion have been obtained from finite element analysis. The rivet hole cracks (damage) in the plate structure gives rise to the non-axisymmetric scattering of Lamb wave, as well as sh...

Lamb waves have shown a great potential in structural health monitoring (SHM) of thin plates that are frequently used in engineering structures. Dense transducer networks or active ultrasonic arrays can be employed to generate and receive Lamb waves. Active arrays, however, enable beam steering and can work as spatial filters enabling assessment of large plate areas from a single fixed position...

the effect of daily oral administration of ephedrine (0, 1, 2, 4 or 8 mg kg-1 w0.75) on carcasscharacteristics of forty-four 2 yr old crossbred (mehraban x ghezel) fat-tailed ewes was studied. theewes were fed a fattening ration, and received ephedrine by using a drenching gun for either 50 or 70days. there was a significant interaction (p

Liposomal amphotericin B (AmBisome(®); LAmB) is a unique lipid formulation of amphotericin B. LAmB is a standard of care for a wide range of medically important opportunistic fungal pathogens. LAmB has a significantly improved toxicity profile compared with conventional amphotericin B deoxycholate (DAmB). Despite nearly 20 years of clinical use, the pharmacokinetics and pharmacodynamics of this...

The variation, with material parameters, of Lamb modes is investigated. Vibration spectra of traction-free elastic plates are generally presented, for a given isotropic material, as a set of dispersion curves corresponding to the various Lamb mode branches. Here, the spectrum variations, with the Poisson ratio nu, are plotted in a dimensionless co-ordinate system in the form of a bundle of curv...
