The probabilistic interpretation was developed by Bohr³ and others^12-15 by using operator formation. Von Neumann's¹⁶ logical structure of quantum mechanics is extended to statistical theory of quantum mechanics. In quantum mechanics, the elementary of the observed object is the property which does not allow to neglect the influence of the measuring devices. The fruitfulness of the deterministic point of view in the classical mechanics give rise to the illusion of its universally observed facts¹². However with the penetration of experimental physics into the atomic domain the inapplicability of the classical approach and the relevance of the statistical concepts in this domain became more evident. The behavior of the atomic and subatomic objects is essentially probabilistic. A quantum version of entropy has been developed by Von Neumann¹⁶. In the present study, we have examined the conjectures of Bohr³ and Von Neumann¹⁶ using the theory of harilially ordered vector spaces. Mackey¹² and Lolmogorov¹¹ developed axiomatic approach related to probability distri-butions and operator theory in Hilbert⁷ spaces. Von-Neumann¹⁶ derived some significant results on quantum logic approach to the foundations of quantum theory.

The design, fabrication and calibration of a d.c. electric field mill to measure electrostatic field of disturbed weather conditions of the atmosphere has been described. The electrical noise and complexity have been reduced by introducing the penchart recorder directly through a Teflon coated coaxial cable in place of pushpull d.c. amplifier, potentiometer and a galvanometer as used by Gunn³. Provision has been made for selecting the desired sensitivity of the electric field meter. The electric field mill provides a reliable output even in periods of severe conditions of the atmosphere.

In common practice thermopowers of metals or conductors are determined from thermo e.m.f. of the thermocouples. In the conventional method, reported in the literature [I.C.T.⁹, Barnard¹], thermopower of the thermocouple is obtained from the temperature derivative of thermo e.m.f. Thermopowers of individual metals are obtained by using thermopowers of the reference metals³. Previous method as well as thermopowers of reference metals have the vital role⁸ in the determination of thermopowers of the test metals. Some points in favour of the need of test of these factors are essential. Moveover, there is a poor agreement between theory and experiment of thermopowers of metals. Either values of thermopowers of a metal reported by two authors or valves obtained with respect to two reference metals or valves of thermopowers of two sample of a metal, hardly agree with each other [I.C.T.⁹, Seitz¹³, Wilson¹⁵, Barnard¹, MacDonal¹¹].

In the present communication we are going to discuss the complicated anomalies, we also test the conventional method for determination of thermo-powers of metals form thermo e.m.f. and accuracy of thermopowers of some reference metals reported in the literature³ and determine the thermopowers of lead. Thermopower of the most popular reference metal⁷ has also been suggested.

This paper focuses on the study of hypertension and status through the logistics regresson models. We are using the data from the Unit of Record, University Science Malaysia Hospital (HUSM). We also provide some numerical results of the statistical calculation. The finding of estimate risk will be used to educate the people consciousness about the dangerous of high blood pressure.
