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.
Abstract The readability of scientific texts is critical for the successful distribution research findings. I replicate a recent study which found that abstracts articles in life sciences became less readable over time. Specifically, sample 28,345 from 17 leading journals field management and organization 3 decades, two established indicators time, namely Flesch Reading Ease New Dale–Chall Read...
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...
We present a detailed response to the critique of "State of the Science of Endocrine Disrupting Chemicals 2012" (UNEP/WHO, 2013) by financial stakeholders, authored by Lamb et al. (2014). Lamb et al.'s claim that UNEP/WHO (2013) does not provide a balanced perspective on endocrine disruption is based on incomplete and misleading quoting of the report through omission of qualifying statements an...
Measured Amplitude Ratio (MAR) is a form of modal analysis for the classification of Acoustic Emission (AE) signals. MAR uses a comparison of the amplitudes of the first two primary lamb wave modes, symmetric (S0) and asymmetric (A0), to determine the orientation of the damage mechanisms in relation to the sensor. Previous researchers have demonstrated that some damage mechanisms, such as delam...
