In order to determine the best form factor formula for Loblolly Pine (Pinus taeda L.) plantations in Talesh (Western Guilan province-Iran), a number of 110 trees were selected based on their distribution in diameter classes, from 12 to 34 cm (in a two- cm diameter interval). First, several quantitative factors including diameter at breast height, diameter at 0.65 m of height, and diameter at st...

Six generations of RPC systems can be distinguished including Federated Method Invocation presented in this paper. Some of them—CORBA, Java RMI, and Web/OGSA services—support distributed objects. However, creating object wrappers implementing remote interfaces doesn’t have a great deal to do with object-oriented distributed programming. Distributed objects developed that way are usually ill-str...

within the past few years, neat scheme has been overturned by the discovery that rna can act as an enzyme. what does the starting finding of rna enzymes imply? thre first implication is that one can no longer assume a protein lies behind every catalytic activity of the cell. it now appears that several of the operations that tailor an ran molecule into its final form are at least in part cataly...

emerging of the industrial revolution caused the dominance of machine in man`s life. at the beginning, man was fascinated by machine; by its order, automation, and its efficiency. then he tried to adapt this mechanistic order to his life and create a completely ordered, clean and predictable environment. thus modern urbanism appeared. in comparison with dark, airless and contaminated industrial...

A logarithmic scaling for structure functions, in the form Sp ∼ [ln(r/η)] ζp , where η is the Kolmogorov dissipation scale and ζp are the scaling exponents, is suggested for the statistical description of the near-dissipation range for which classical power-law scaling does not apply. From experimental data at moderate Reynolds numbers, it is shown that the logarithmic scaling, deduced from gen...
