A preliminary test single stage Shrinkage (PTSSS) techniques is used for estimation the scale parameter q of an exponential distribution when a prior knowledge about q is a available in the form of initial estimate q0 of q. It is proposed to estimate q by a testimator  that is based upon the result of a test of the hypothesis H0 :q = q0 against the hypothesis HA :q ¹ q0 with level of significance a. If H0 is accepted we take , where the weighting factor  is a function of the test statistic for testing H0 or may be constant such that . However if H0 is rejected we take , where  and  is the classical estimator of q (MLE). Choosing the weighting factor , (i =1,2) appropriately, an expression for the mean squared error (MSE) and Bias of  are derived and comparisons are made with classical estimator () in the sense of efficiency and last earlier studies.

Batch and flow injection spectrophotometric methods for determination of Ceftazidime in pharmaceutical formulations
...Show More Authors

It is generally accepted that there are two spectrophotometric techniques for quantifying ceftazidime (CFT) in bulk medications and pharmaceutical formulations.  The methods  are described as simple, sensitive, selective, accurate and efficient techniques. The first method used an alkaline medium to convert ceftazidime to its diazonium salt, which is then combined with the 1-Naphthol (1-NPT) and 2-Naphthol (2-NPT) reagents. The azo dye that was produced brown  and red in color with absorption intensities of ƛmax 585 and 545nm respectively. Beer's law was followed in terms of concentration ranging from  (3-40) µg .ml-1 For (CFT-1-NPT) and (CFT-2-NPT), the detection limits were 1.0096 and 0.8017 µg.ml-1, respec
