Hopper Index [degrees], HI = the recommended conical half-angle (measured from the vertical) to ensure flow at the walls. Usually add 3° to account for variability. Values range 14-33° with 304 s/s. 

Chute index [degrees]. Cl, = recommended chute angle (with the horizontal) at points of solids impact. Values = angle of slide, values = 20-90°. High values suggest particles stick to sides of mixer or bins. 

Adhesion angle index [degrees], AAI = difiference between angle of shde (with horizontal) after an impact pressure of 7 MPa or (Cl -10°) and the angle of slide without impact pressure. 

However, the most interesting and incomprehensible in the nature of the stretched exponential law is the fact that for more experimental regularities the index degree is near to 0.6. 

The tendency for a solvent to form deposits by polymerization of impurities such as olefins is measured by the test for potential gums . Olefin content can also be represented by the bromine index , which is a measure of the degree of unsaturation (see paragraph 3.4.1). 

Extension to six dimensions is now straightforward. We obtain similar expressions just with the y and z components and the index n running over the basis functions included in the particular degree of freedom. For the functions... 

The Randic connectivity index, X, is also called the connectivity index or branching index, and is defined by Eq. (18) [7], where b runs over the bonds i-j of the molecule, and and dj are the vertex degrees of the atoms incident with the considered bond. 

Dow Fire and Explosion Index. The Dow Eire and Explosion Index (3) is a procedure usehil for determining the relative degree of hazard related to flammable and explosive materials. This Index form works essentially the same way as an income tax form. Penalties are provided for inventory, extended temperatures and pressures, reactivity, etc, and credits are appHed for fire protection systems, process control (qv), and material isolation. The complete procedure is capable of estimating a doUar amount for the maximum probable property damage and the business intermptionloss based on an empirical correlation provided with the Index. 

EinaHy, the penalties are factored into the original material factor to result in a fire and explosion index value. The higher this value, the higher the degree of hazard. 

Other methods are also available for the estimation of diesel fuel quaUty. For example, the diesel index (DI) is defined by the relation DI = (A° F X ° API)/100, where A °F is the aniline point in degrees Fahrenheit and °API is the American Petroleum Institute gravity. A high aniline point corresponds to a high proportion of paraffins in the diesel fuel such a fuel has a high diesel index and, therefore, a high cetane number. 

The perturbation of the PMD symmetry is accompanied by a decrease in the charge alternation and by the appearance of bond alternation from one end group to another. The bond alternation ampHtude has been revealed to be proportional to the asymmetry degree, which can be calculated as the difference of topological indexes = 4>gj — 4>gg. The effect is maximum if Tgj > 45° and Tgg < 45°. If A4>j2 = 90°, the ideal polyene state is...
