The sera of several animals were examined for suitability in coagulase testing. The assay for coagulase-reacting factor (CRF) activities of the whole sera indicated the following relative concentrations of CRF: human > pig > rabbit > horse > bovine, chicken, and lamb. Human, pig, and rabbit sera had adequate amounts of CRF for coagulase testing. The plasmin activities of the different sera, arr...

| Damage detection using guided Lamb waves is an important tool in Structural health Monitoring. In this paper, we outline a method of obtaining Lamb wave modes in composite structures using two dimensional Spectral Finite Elements. Using this approach, Lamb wave dispersion curves are obtained for laminated composite structures with different fibre orientation. These propagating Lamb wave modes...

We study the survival of a single diffusing lamb on the positive half line in the presence of N diffusing lions to the right of the lamb and a haven at x = 0. If the lamb reaches this haven before meeting any lion, the lamb survives. We investigate the survival probability of the lamb, SN (x,L), as a function of N and the respective initial positions of the lamb and the lions, x and L. We deter...

Signal sequences function in protein targeting to and translocation across the endoplasmic reticulum membrane. To investigate the structural requirements for signal sequence function, chimeras of the Escherichia coli LamB signal peptide and prolactin were prepared. The LamB signal peptide was chosen by virtue of the extensive biophysical and biological characterization of its activity. In vitro...

The present study evaluated the effect of controlled ryegrass-white clover herbage availability from day 128 until day 142 of pregnancy in comparison to unrestricted availability, on the performance of twin-bearing ewes of varying body condition score (BCS; 2.0, 2.5, or 3.0) and their lambs. It was hypothesised that under conditions of controlled herbage availability, the performance of lambs b...

The appearance of newly induced LamB protein at the cell surface of Escherichia coli was followed topographically by immuno-electron microscopy. LamB protein was induced in E. coli wild-type or lac-lamB cells for a short period of time (4 to 6 min), such that the overall level of LamB protein in induced cells was at least twofold higher than that in uninduced cells. Antibodies bound to LamB pro...

Effects of percentage of roughage on growth, serum urea N, NEFA, and IGF-1 concentrations and wool, carcass, and fatty acid (FA) characteristics were investigated in Rambouillet wether lambs (n = 33). Lambs were individually fed ad libitum pelleted diets for 98 d containing 40% dried distillers grains and other ingredients, with 10% (CSH10), 20% (CSH20), or 30% (CSH30) cottonseed hulls replacin...

a four- year-old moghanian breed ewe was admitted to the large animal veterinary clinic, university of tabriz due to dystocia. during obstetrical examination, it was revealed that the cervix has been closed firmly and vagina protruded about 5 cm through the vulva (vaginal prolaps). based on clinical findings and for saving the dam and lamb(s), the cesarean section was done. a normal alive femal...

Effects of using ground redberry juniper and dried distillers grains with solubles (DDGS) in Rambouillet lamb (n = 45) feedlot diets on growth, blood serum, fecal, and wool characteristics were evaluated. In a randomized design study with 2 feeding periods (Period 1 = 64% concentrate diet, 35 d; Period 2 = 85% concentrate diet, 56 d), lambs were individually fed 5 isonitrogenous diets: a contro...

Twin-bearing Targhee ewes (Exp. 1, 1 yr, n = 42) and 1,182 single- and twin-bearing whiteface range ewes (Exp. 2, n = 8 experimental units over 2 yr) were used in a 2 x 2 factorial arrangement of treatments to determine the effect of supplemental energy source and level of vitamin E supplement on lamb serum metabolites and thermogenesis (Exp. 1) and on lamb growth (Exp. 2). During late gestatio...
