The simplest (stationary) queueing models with catastrophes have been studied some years ago, see for instance [1–6, 9]. Namely, when the queue is not empty, catastrophes may occur with the respective rates. The effect of each catastrophe is to make the queue instantly empty. Simultaneously, the system becomes ready to accept new customers. Nonstationary Markovian queueing models (birthdeath pr...

Two experiments were conducted to investigate the effect of Mn source on Mn absorption by the intestine of broilers. In Experiment 1, the effect of Mn source, including MnSO(4), 2 Mn-amino acid chelates (Mn-Gly and Mn-Met) synthesized in our laboratory, 3 Mn-amino acid complexes with different complex strengths (Mn-Met E, Mn-AA A, and Mn-AA B), and 2 mixtures of MnSO(4) with Gly or Met, on Mn a...

In order to investigate mineral manganese forms and their relations with plant responses, 22 soil samples from Fars province (0-20 cm) were in a greenhouse experiment filled in 3 liter pots, and soybean (Glycine max (L.) merr.,CV.Williams) was grown for 7 weeks. Chemical forms of manganese were determined in soils by warden and Reisenauer sequential extraction method (readily soluble, weakly ad...

Although manganese (Mn) is an essential trace element for human development and growth, chronic exposure to excessive Mn levels can result in psychiatric and motor disturbances, referred to as manganism. However, there are no known mechanism(s) for efflux of excess Mn from mammalian cells. Here, we test the hypothesis that the cytoplasmic iron (Fe) exporter ferroportin (Fpn) may also function a...
