acacia nilotica (thorn mimosa) is used locally for various medicinal purposes by traditionalists and herbalists in northeastern nigeria. plants products have been used since ancient times in the management of various conditions. the bark of a. nilotica has been reported to be used traditionally to manage diabetes, dysentery, leprosy, ulcers, cancers, tumor of the eye, ear and testicles, indurat...

cobalt is one of the most important constituent present in ceramic industries. glazers are the relevant workers when they are producing blue colored ceramic, causing occupational exposure to such metal. through this study, urinary cobalt was determined in glazers in a ceramic industry when they were producing blue-colored ceramic glazes.in this case-control study, spot urine samples were collec...

the time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. it is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. the phase dependence of the atom-field entanglement is...

We demonstrate interference of spontaneous emission of light from two distant solid-state atomic ensembles, when both ensembles are coherently excited by a common laser source. Owing to a strong collective enhancement of the spontaneous emission, the atoms behave as ideal two-level quantum systems and no which-path information is left in the atomic ensembles after emission of a photon. This all...
