31P NMR spectra of phosphate and phosphonate complexes of Escherichia coli alkaline phosphatase have been obtained by Fourier transform NMR methods. One equivalent of P1i, bound to Zn(II) alkaline phosphatase, pH 8, gives rise to a single 31P resonance 2 ppm downfield from that for Pi, and assignable to the noncovalent complex, E-P. Inorganic phosphate in excess of 1 eq per enzyme dimer gives r...

Acceptance control charts are effective tools tomonitor capable processes in which the fraction of the produced nonconforming items is very low. In these charts, some controlled changes in the process mean are allowed, and the production of a specified number of defectives is tolerated. Designing these acceptance control charts by considering the cost of sampling, detecting, and investigating o...

42nd Gurkhas, Manipur. S. A., a rifleman, came to hospital witn purulent "ophthalmia of one eye. The history was as follows : Whilst out shooting five days ago in going through the thick jungle he felt some thing suddenly hit his eye. Beyond the eye watering lie felt no more discomfort, and took no notice of it. However, two days after his eye inflamed, lie had pain, lachrymation and photophobi...

Problem statement: Although economic Xbar-R chart designs do guarantee the minimal operating cost, they typically have poor levels of statistical performance measures. The obvious limitation of the economic design is that the Type I error rate seems to be very high for many situations and will cause a large number of false alarms. This situation leads to an investigation of appropriate levels o...

In many manufacturing processes, some key process parameters have very strong relationship with the normal or various faulty products of finished products. The abnormal changes of these process parameters could result in various categories of faulty products. In this paper, a data mining model is developed for on-line intelligent monitoring and diagnosis of the manufacturing processes. In the p...

Control charts are standard statistical process control (SPC) tools for detecting assignable causes. These charts trigger a signal when a process gets out of control but they do not indicate when the process change has begun. Identifying the real time of the change in the process, called the change point, is very important for eliminating the source(s) of the change. Knowing when a process has ...

Reduction of Zr(IV) metallocenium cations with sodium amalgam (NaHg) produces EPR signals assignable to Zr(III) metallocene complexes. The chloro-bridged heterodinuclear ansa-zirconocenium cation [(SBI)Zr(μ-Cl)2AlMe2](+) (SBI = rac-dimethylsilylbis(1-indenyl)), present in toluene solution as its B(C6F5)4(-) salt, thus gives rise to an EPR signal assignable to the complex (SBI)Zr(III)(μ-Cl)2AlMe...

ber, 1866. She applied for relief on account of the pain and inconvenience caused by a large tumour of the right breast, of which she gave the following history : About two years ago, without any assignable cause, her breast suddenly began to pain her, and she noticed that it was somewhat enlarged and swollen. She applied to a Hakeem, who gave her some medicines which proved ineffectual; the pa...
