There are various approaches to computing dry rock bulk modulus as a function of porosity and, from this, inferring velocity and density changes due to reservoir fluid change as a function of porosity. One such approach is the pore space stiffness method. A second approach is the critical porosity model (Mavko and Mukerji, 1995). Using the clean sandstones at different pressures from a dataset ...

The primary catabolic fate of glycine in mammals involves the hepatic glycine-cleavage system in which glycine is sequentially converted to CO,, NH,, NADH + H + , and NS, N"-methylenetetrahydrofolate (Fig. 1) (for review, see Kikuchi, 1973). This multi-enzyme reaction is located exclusively in the mitochondrial compartment (Motokawa 81 Kikuchi, 1971) and can be compared in several respects with...

There are a variety of methods that can be used to extract rock-properties information from seismic data. Three of the methods that can be used, include; 1. AVO analysis, followed by post-stack inversion of the AVO attributes (Goodway, et al.) 2. Prestack inversion of the P-wave data directly to impedance (Hampson et al.) 3. Joint prestack inversion of the P-wave data and converted wave data di...

Lower level of health-related quality life has the potential to be experienced by adolescents with low socioeconomic status. This condition can hamper productivity who will enter their productive age. For this reason, it is important strive enhancement among status, especially involving family as adolescents’ microsystem. research an effort collect empirical information that used in improving h...

let g = (v, e) be a simple graph. hosoya polynomial of g isd(u,v)h(g, x) = {u,v}v(g)x , where, d(u ,v) denotes the distance between vertices uand v. as is the case with other graph polynomials, such as chromatic, independence anddomination polynomial, it is natural to study the roots of hosoya polynomial of a graph. inthis paper we study the roots of hosoya polynomials of some specific graphs.
