As a communication link between suburban and urban roads, terminals prevent buses from entering the cities, thus, they play an important role in improving traffic flow, reducing urban environmental pollution. Clearly, proximity of te rminals to cities will bring about environmental pollution in different forms (soil, water, air and wastewater). The current study tries to investigate the environ...

The stack frame technique for dynamic local variable storage in Algol and descendant languages may be adopted in Forth to expand the number of elements easily handJed directly on the stack, reducing the need for variables. The required extensions to Forth can preserve the interactive quality of Forth by using the parameter stack exclusively and by using a built-in set of local variable names ra...

since the verbs of and have similar use and play an important role in arabic grammar, it was useful to study both and discuss about their functions. following the discussion we found that there is five different functions for :first, it is an imperfect verb, (that give the noun an nominative case and the comment an objective case) arabic grammar experts disagree if it has a verb function or a n...

A Proposed Federal Policy for the Protection of Human Subjects published November 10, 1988 (53 FR 45661) has been revised in response to public comments. The Poli...

This article outlines a curriculum for resident education in musculoskeletal radiology that addresses the current requirements for assessment of the general competencies as set forth by the Accreditation Council for Graduate Medical Education.

We report on various results, conjectures, and open problems related to KazhdanLusztig polynomials of matroids. We focus on conjectures about the roots of these polynomials, all of which appear here for the first time.

There is a typographical error in a sentence following (20) in [1, p.1681], in which an extra parenthesis appears. The corrected sentence is as follows. Therefore, p(v) is a Gibbs distribution p(v) = 1=Vintexp E . Also, the authors’ photographs and biographies did not appear in [1], and they now appear below. In addition, some of the information in references [9], [24], and [28] has changed. Th...

We derive twistorial tensionful bosonic string action by considering on the world sheet the canonical twistorial 2–form in two–twistor space. We demonstrate the equivalence of or model to two known momentum formulations of D = 4 bosonic string, with covariant worldsheet vectorial string momenta P m μ (τ, σ) and the one with tensorial string momenta P[μν](τ, σ). All considered here string action...
