This article describes the geomorphological and petrological characteristics of 19 submerged beachrocks located on north Catalan coast (western Mediterranean Sea). Their length ranges between 8 1039 m, their width 1.5 86.5 m thickness 0.4 3.25 m. They are siliciclastic consisting well-rounded gravels with a very coarse sand matrix, they have low proportion bioclasts (<1%). Cementation occurr...

The understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. This paper reports a dynamic simulation study of the possible distillation columns sequences of Dew pointing unit in the second phase of South Pars Gas Refinery. In this unit, three columns are u...

A non-abelian finite group is called sequenceable if for some positive integer , is -generated ( ) and there exist integers such that every element of is a term of the -step generalized Fibonacci sequence , , , . A remarkable application of this definition may be find on the study of random covers in the cryptography. The 2-step generalized sequences for the dihedral groups studi...

Several ranges encompassing more than 35,000 km 2 of Sonora, Mexico, contain distinctly lineated and foliated granitic and metamorphic rocks that constitute the lower plates of metamorphic core complexes. Penetrative deformation is characterized by gently dipping mylonitic foliation across which northeast trending stretching lineation is everywhere developed. Prominent northwest trending fractu...

In this article, a class of convergent series based on Fibonacci sequence is introduced for which there is a golden ratio (i.e. $frac{1+sqrt 5}{2}),$ with respect to convergence analysis. A class of sequences are at first built using two consecutive numbers of Fibonacci sequence and, therefore,  new sequences have been used in order  to introduce a  new class of series. All properties of the se...

Abstract The Svalbard Composite Tectono-Sedimentary Element (SCTSE) is located on the northwestern corner of Barents Shelf and comprises a Carboniferous–Pleistocene sedimentary succession. Due to Cenozoic uplift, succession subaerially exposed in archipelago. oldest parts consist Carboniferous–Permian mixed siliciclastic, carbonate evaporite, spiculitic sediments that developed during multiple ...

Abstract. To expand traditional cyclostratigraphic numerical methods beyond their common technical limitations and apply them to truly deep-time archives, we need reflect on the development of new approaches sedimentary archives that are not traditionally targeted for analysis but frequently occur in impoverished record. Siliciclastic storm-dominated shelf environments a good example such recor...
