Studies on the germicidal activity of chlorine, bromine, and iodine were made by use of the Association of Official Agricultural Chemists official first action method for determining effectiveness of swimming pool water disinfectants. In this procedure, 0.3 ppm of available chlorine as chlorine gas has activity equivalent to 0.6 ppm of available chlorine in the buffered sodium hypochlorite cont...

Recent theoretical research shows that in asset markets vague state probabilities lead to price volatility, trading inertia, and may worsen risk-sharing efficiency, whereas Subjective Expected Utility theory implies that prices, volumes, and final allocations for risky and uncertain assets should be equivalent. We investigate experimentally whether prices, trading, and final allocations are aff...

Given matrices A and B shift equivalent over a dense subring R of R, with A primitive, we show that B is strong shift equivalent over R to a primitive matrix. This result shows that the weak form of the Generalized Spectral Conjecture for primitive matrices implies the strong form. The foundation of this work is the recent result that for any ring R, the group NK1(R) of algebraic K-theory class...

some of the difficulties and misunderstandings that happen in accounting theory, practice, regulation and education are grounded in language and linguistics. as an illustration of this the persian equivalent of 'accounting' is linguistically analysed to reveal how a mistranslation may cause difficulties in understanding and improving iranian accounting. this paper shows how hesaabdaar...

We surveyed every state and the District of Columbia to see what patient specific information states release on hospital visits and how much potentially identifiable information is released in those records. Thirty-three states release hospital discharge data in some form, with varying levels of demographic information and hospital stay details such as hospital name, admission and discharge dat...

Resolution refinements called w-resolution trees with lemmas (WRTL) and with input lemmas (WRTI) are introduced. Dag-like resolution is equivalent to both WRTL and WRTI when there is no regularity condition. For regular proofs, an exponential separation between regular dag-like resolution and both regular WRTL and regular WRTI is given. It is proved that DLL proof search algorithms that use cla...

This paper presents a control methodology that enables nonlinear model based control of pulse width modulated (PWM) pneumatic servo actuators. An averaging approach is developed to describe the equivalent continuous-time dynamics of a PWM controlled nonlinear system, which renders the system, originally discontinuous and possibly non-affine in the input, into an equivalent system that is both c...
