danehkhoshk anticline is a typical growing anticline in kermanshah province which is located in folded zagros belt. the purpose of this research is to evaluate the effect of tectonic on the triangular facet characteristics, the drainage density and on the drainage pattern formed on anticline. dimensions of triangular facets were determined by means of quickbird satellite images and field works....

The STL de facto data exchange standard for Solid Freeform Fabrication represents CAD models as a collection of unordered triangular planar facets. No topological connectivity information is provided; hence the term “bucket of facets.” Such topological information can, however, be quite useful for performing model validity checking and speeding subsequent processing operations such as model sli...

The photomediated synthesis of silver right triangular bipyramids and prisms has been studied, and we have determined that pH and [BSPP]/[Ag(+)] ratio (bis(p-sulfonatophenyl)phenylphosphine, BSPP) finely control the reaction rate and, consequently, the crystal growth pathway and morphology of final products. A fast reaction rate, realized at a high pH such as 10 or 11 and a [BSPP]/[Ag(+)] ratio...

the study area, paykola anticline, is located in the southwestern part of kermanshah province. the aim of this research is to evaluate the geomorphological indexes of active tectonics in paykola anticline as well as to study the effect of tectonic in the form and direction of geomorphological landforms. to achieve the aim of study, the lithological and tectonic characteristics of study area wer...

The Campos do Jordão Plateau, situated in the Serra da Mantiqueira – western flank of Continental Rift Southeastern Brazil, presents several morphological features that are indicative neotectonic activity. This paper a morphotectonic map southeastern front plateau (scale 1:25,000), based on detailed photointerpretation, with structural data obtained during field surveys and also supported by mo...

A total order of the facets of a polytope is a geometric shelling if there exists a combinatorially equivalent polytope in which the corresponding order of facets becomes a line shelling. The subject of this paper is (geometric) shellings of 3-polytopes. Recently, a graph theoretical characterization of geometric shellings of 3-polytopes were given by Holt & Klee and Mihalisin & Klee. We rst gi...

We use a concrete shelling order of chessboard complexes ∆n,m for m > 2n − 1 to describe the type of each facet of ∆n,m in this order. Further, we find some recursive relations for h-vector, describe the generating facets of shellable ∆n,m and show that the number of generating facets of ∆n,m is the value of a special Poisson-Charlier polynomial pn(m). Some of these results can be extended to c...

Bacteriol. 90:254-261. 1965.-The capsids of adenovirus type 2 were fragmented by treatment with low concentrations of sodium lauryl sulfate. The clusters of capsomeres resulting from this treatment displayed characteristic patterns. Some o...

The cut polytope of a graph arises in many fields. Although much is known about facets of the cut polytope of the complete graph, very little is known for general graphs. The study of Bell inequalities in quantum information science requires knowledge of the facets of the cut polytope of the complete bipartite graph or, more generally, the complete k-partite graph. Lifting is a central tool to ...

Mr. C. Stephanos posed the following question in the “Intermédiaire des Mathématiciens ” [3]: “Do there exist polyhedra with invariant facets that are susceptible to an infinite family of transformations that only alter solid angles and dihedrals?” I announced, in the same Journal [4], a special concave octahedron possessing the required property. Cauchy, on the other hand, has proved [5] that ...
