conclusion fm is more sensitive than zn for diagnosis of tb. however, since fm is more sensitive and rapid, using this method in clinical laboratories with large specimen numbers is recommended. results a total of 102 out of 920 study subjects had pulmonary tb, of them 68 (66.66%) patients were smear positive by either staining method while others were smear negative. the proportion of positive...

The high-throughput Zn reduction method was developed and optimized for various biological/biomedical accelerator mass spectrometry (AMS) applications of mg of C size samples. However, high levels of background carbon from the high-throughput Zn reduction method were not suitable for sub-mg of C size samples in environmental, geochronology, and biological/biomedical AMS applications. This study...

Integral bases, a minimal set of solutions to Ax ≤ b, x ∈ Zn that generate any other solution to Ax ≤ b, x ∈ Zn, as a nonnegative integer linear combination, are always finite and are at the core of the Integral Basis Method introduced by Haus, Köppe and Weismantel. In this paper we present one generalization of the notion of integral bases to the nonlinear situation with the intention of creat...

Let the random variable Zn,k denote the number of increasing subsequences of length k in a random permutation from Sn, the symmetric group of permutations of {1, ..., n}. In a recent paper [4] we showed that the weak law of large numbers holds for Zn,kn if kn = o(n 2 5 ); that is, lim n→∞ Zn,kn EZn,kn = 1, in probability. The method of proof employed there used the second moment method and demo...

Proportional Integral Derivative (PID) Controller is a primary component in industrial control systems nowadays. Its gain parameters have a powerful effect on its transient response criteria such as integral squared error (ISE), settling time, rise time and overshooting. Tuning gain parameters of PID to reach the optimal transient response of control systems is a hard problem. The standard meth...

A new method has been developed for the study of zinc metabolism in man using the stable isotope 67Zn. The technique involves intravenous infusion of the isotope followed by measurements of the plasma and faecal enrichments over a period of days. A procedure for the analysis of Zn isotopes in plasma and faeces is described which requires the separation of Zn from other elements using the chelat...

This paper proposes a direct-construction realization procedure which simultaneously treats all the involved variables and/or uncertain parameters and directly generates an overall Roesser model realization or LFR model for a given nD causal transfer matrix with rational function or polynomial entries. It is shown that the nD realization problem for an nD transfer matrixG(z1, . . . , zn), which...
