Advanced techniques for observing protein localization in live bacteria show that the distributions are dynamic. For technical reasons, most such techniques have not been applied to outer membrane proteins in Gram-negative bacteria. We have developed two novel live-cell imaging techniques to observe the surface distribution of LamB, an abundant integral outer membrane protein in Escherichia col...

Scrapie is one of several transmissible spongiform encephalopathies of livestock. Disease susceptibility is linked to polymorphisms in the normal prion protein gene that encodes the mammalian prion precursor. Codon 171 of this gene is a major determinant of scrapie susceptibility. Selection for arginine (R) at codon 171 is encouraged by the USDA to decrease the incidence of scrapie. Objectives ...

twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. treatments consisted of 8 (t1), 4 (t2) or 2 (t3) feeding buckets/pen (8 lambs/pen). during the experiment, concentrate was fed at 08:30 in individual feeders. daily dry matter intake (dmi...

We compared the efficacy of combination posaconazole-liposomal amphotericin B (LAmB) therapy to monotherapy with either drug in diabetic ketoacidotic or neutropenic mice with disseminated zygomycosis caused by Rhizopus oryzae. Combination therapy was no better than LAmB alone, and posaconazole monotherapy did not improve survival or reduce fungal burden versus placebo.

The model developed in this paper allows to predict the propagation of Lamb waves in an anisotropic wafer. More generally it can account for the linear dispersive propagation of scalar waves in an anisotropic and finite plate and for any local alteration in the displacement component of the Lamb Wave. The validation has been done using a solid-solid contact as an emitter-receiver.

The maximal acceleration corrections to the Lamb shift of one– electron atoms are calculated in a non–relativistic approximation. They are compatible with experimental results, are in particularly good agreement with the 2S − 2P Lamb shift in hydrogen and reduce by ∼ 50% the experiment-theory discrepancy for the 2S − 2P shift in He. PACS: 04.90.+e, 12.20.Ds.

Corrections to hyperfine splitting and Lamb shift of order α(Zα) induced by the diagrams with radiative photon insertions in the electron line are calculated in the Fried-Yennie gauge. These contributions are as large as −7.725(3)α(Zα)/(πn)(mr/m) m and −0.6711(7)α(Zα)/(πn)EF for the Lamb shift and hyperfine splitting, respectively. Phenomenological implications of these results are discussed wi...

The proton structure and proton polarizability corrections to the Lamb shift of electronic hydrogen and muonic hydrogen were evaluated on the basis of modern experimental data on deep inelastic structure functions. Numerical value of proton polarizability contribution to (2P-2S) Lamb shift is equal to 4.4 GHz.

Platelike structures, made of composites, are being increasingly used for fabricating aircraft wings and other aircraft substructures. Continuous monitoring of the health of these structures would aid the reliable operation of aircrafts. This paper considers the use of a Lamb wave based structural health monitoring SHM system to identify and locate defects in large multilayered composite plates...

Effect of various voltage of electrical stimulation (ES) on meat quality of lamb and goat was investigated by using a total of 36 animals at 3-5 years old. Constant 50 Hz frequency and 50, 100, and 250 V, 90 sec of ES were administered to 1/2 carcasses and were examined according their textural, physicochemical, and sensorial characteristics. ES decreased the pH values of lamb and goat meat, an...
