Abstract Effects of enzymatic and microbial feed supplements on fecal pathogen shedding were tested in a 2×2 factorial, randomized complete block design, where the experimental unit (n = 20) was pen 3 lambs. Lambs blocked (i =10) by weight then randomly assigned within to phase 1 treatments control (C) or enzyme product (E). Upon acclimation diet, pens treated daily as E (1.1 g per animal Maxim...

The preparation of tellurite glasses with persistent luminescence by adding luminescent particles in the glass melt is reported. Compared to phosphate glasses, afterglow from low, indicating that more corrosive on than melt. However, as opposed no emission Eu3+ was detected photoluminescence spectra when crushed into powder. We show a confocal Raman microscope can be used evidence presence glas...

This work describes the comparison of the amplification characteristics (gain) and the Noise figure (NF) of the Thulium and Erbium in three different host materials which the Yttria Alumina-Silica glass, Fluoride and Tellurite fiber glass. The gain using these host materials covers the range 1.45-1.65 μm. Thulium doped fiber amplifier (TDFAs) operated in the region of wavelength (1480-1510 nm) ...
