INDEX expression

The Process Inherent Safety Index expresses the inherent safety of the process itself including the equipment and operating parameters. The Index has been divided into subindices for inventory, temperature, pressure, equipment safety and safe process structure. 

In this thesis an inherent safety index for evaluating inherent safety in preliminary process design was presented. The inherent safety of a process is affected by both chemical and process engineering aspects. These have been dealt separately, since the index was divided into the Chemical Inherent Safety Index and the Process Inherent Safety Index. These two indices consist of several subindices which further depict specific safety aspects. The Chemical Inherent Safety Index describes the inherent safety of chemicals in the process. The affecting factors are the heat of the main reaction and the maximum heat of possible side reactions, flammability, explosiveness, toxicity, corrosiveness and the interaction of substances present in the process. The Process Inherent Safety Index expresses safety of the process itself. The subindices describe maximum inventory, maximum process temperature and pressure, safety of equipment and the safety of process structure. 

This index, N2, is defined as the number of distinct ways in which an acyclic — —C fragment can be superimposed on the hydrogen-depleted molecular graph. The N2 index expresses the number of all paths of length two, P2, in the graph ... 

Concerning the properites of tannins, we have stressed the importance of their structure, even more than their state of condensation or molecular weight. As it is impossible to separate and identify the flavolans in a given plant sample, one must be content with finding the aggregate indexes expressing the median state of polymerization. 

NCRP believes that use of a risk index expressed in terms of dose is acceptable and desirable as long as (1) the units of the numerator and denominator are consistent at a conceptual level, (2) the assumptions embodied in the proportionality constants between dose and response for substances that cause stochastic responses are clearly stated, and (3) the allowable doses are adjusted when the proportionality constants between dose and response for substances that cause stochastic responses or the thresholds for substances that cause deterministic responses change significantly.

It is significant that with the uncertainty methodology both the major analytical properties, accuracy and representativeness [23], which quality of analytical data relies on, can be quantified and properly taken into account to give a single index of accuracy. This index expresses consistency between the measurement results and the true value that refers to a bulk sample of the material rather than the test portion analysed. 

Urine should be collected in 6 mol/L HCl, 20 to 30 ml for a 24-hour specimen, to avoid precipitation of phosphate complexes. Simultaneous measurement of phosphate and creatinine in serum and urine with fasting morning spot or 1- to 2-hour timed collections permits calculation of the renal phosphate threshold (TmPO /GFR). The clearance of phosphate divided by creatinine clearance can be plotted on a nomogram, and the TmP04/GFR determined. This index expresses phosphate reabsorption as a function of both serum phosphate concentration and GFR and is more useful than urinary phosphate excretion. 

The square root of the variance is the standard deviation, represented either, when the number n of measurements is small, by or by cr when a large statistical population of values is available (expression 22.8). The standard deviation is a dispersion index expressed in the same units as x. 

The volumetric fraction, X, is a practical index that encompasses the dispersion coefficient. It includes all the above-mentioned indices and holds for the various modes of segmented and unsegmented-flow systems, as well as for batch analysis. This general index expresses the relative contribution of a solution to any given fluid element located anywhere in the manifold at any time. In this book, the notation for the volumetric fraction [115] is...

In order to compare the cost-effectiveness of the two measures, the cost-effectiveness ratio for both measures is calculated. The cost-effectiveness ratio for safety measures 1 and 2 is equal to C /Z and C2/Z2, respectively. Safety measure 1 is more cost-effective than safety measure 2 if Ci/Z < C2IZ2. To see whether safety measure 1 is preferred to status quo or not, the cost-effectiveness ratio has to be compared with a reference value, R. The reference value clarifies how much money the decision-maker is willing to pay to obtain one unit of effectiveness. Implementation of the safety measure is preferred to status quo if the decision-maker is willing to pay more to obtain one unit of effectiveness than the cost-effectiveness index expresses, which means that safety measure 1 is preferred to status quo if / > (C,/Z,). 

The equations of Nienow et al. were modified later by Rice and Brainnovich (1986) and Peeler and Huang (1989). A more recent study on segregation by size difference was conducted by Wu and Baeyens (1998). They found that the excess gas flow rate required to prevent segregation in a fluidized bed with a wide size distribution of powder can be calculated from the mixing index expression shown in the equation...
