The current theoretical status of the Lamb shift in He is discussed. Recent calculations of twoloop binding corrections to the Lamb shift significantly shift the theoretical value of the “classic” Lamb shift in He, i.e. of the 2S1/2–2P1/2-interval. In this brief research note, we present a new (theoretical) value for this interval which reads 14041.474(42) Mhz. The theoretical uncertainty is re...

We have compared the activities of liposomal amphotericin B (LAMB) at 3, 5, 10, and 20 mg/kg/day and amphotericin B deoxycholate (AMB) at 1.5 and 2.5 mg/kg/day in a murine systemic infection by Fusarium verticillioides. Survival was improved by all treatments except AMB at 1.5 mg/kg/day. The tissue burden in liver was reduced by LAMB at all dosages and by AMB at 2.5 mg/kg/day. The two highest d...

The efficacies of liposomal amphotericin B (LAmB) and amphotericin B deoxycholate (AmB) were compared in a diabetic murine model of hematogenously disseminated Rhizopus oryzae infection. At 7.5 mg/kg of body weight twice a day (b.i.d.), LAmB significantly improved overall survival compared to the rates of survival in both untreated control mice (P = 0.001) and mice treated with 0.5 mg of AmB pe...

Quick Facts... •Meeting protein, energy, vitamin and mineral requirements is essential for profitable lamb finishing. •Feedlot lambs are more efficient when self-fed than when hand-fed twice daily. •Lambs fed whole grains have as good or better performance than when they are fed rolled or ground grains. •If lamb finishing rations are more than 60 percent roughage, they should be pelleted for be...

In our Institute lumpy skin disease virus is grown on primary lamb testis cells for isolation, identification and vaccine production. However, the availability of lambs in Kenya has been seriously reduced over the past few years. This has led to an increase in the cost of using primary lamb testis cells. This study was undertaken to investigate other primary cell lines, which are easily availab...

Mucormycosis is a rare but invasive and potentially lethal infection caused by ubiquitous fungi of the order Mucorales. The primary mode of infection is inhalation of fungal spores. Rhinocerebral and pulmonary infections are most common, however, other organ systems including the central nervous system can be affected, presumably by occult fungemia. We describe the prolonged treatment course (>...

Based on the thermoelastic mechanism of laser ultrasonic, the problems of the thermal conduction and the coupling between the motion of solid and fluid are solved by using the finite element method. And then the transient waveforms of leaky Lamb waves induced by pulse laser action on the air-aluminum interface are obtained. Experimental signals of laser-induced leaky Lamb waves at the air-alumi...

We propose to adopt the precisely measured anomalous magnetic moment and Lamb shift as tests for the possible existence of the radiatively induced Lorentz and CPT violation effects in quantum electrodynamics. To this end we calculate the one-loop vacuum polarization tensor and vertex radiative correction in dimensional reduction and on-shell renormalization scheme. We then explicitly show how t...

We study quantum optical properties of a dipole emitter coupled to a rectangular nanoscale waveguide with dielectric core and silver cladding. We investigate enhanced spontaneous emission and the photonic Lamb shift for emitters whose resonant frequencies are near the waveguide frequency cutoff where the waveguide behaves as an ɛ-near-zero metamaterial. Via a dyadic Green's function-based field...

We obtain a general result for the Lamb shift of excited states of multilevel atoms in inhomogeneous electromagnetic structures and apply it to study atomic hydrogen in inverse-opal photonic crystals. We find that the photonic-crystal environment can lead to very large values of the Lamb shift, as compared to the case of vacuum. We also suggest that the position-dependent Lamb shift should exte...
