Geomorphological Landforms and processes are of the most significant parameters that affect the distribution and quality of construction materials especially aggregates. The purpose of this research is to evaluate the effect of geomorphological landforms and processes in the formation and quality of construction materials with emphasis on aggregates in Qalehshahin catchment. Qalehshahin catchme...
The article is devoted to the analysis of semantics and features functioning textual bond "bolee togo" [moreover]. aim work was identify specifics this bond, taking into account its semantic in texts various functional styles genres. Moreover, following research methods have been applied comprehend bond: traditional descriptive method, including observation, generalization systematization lingu...
In this paper, the linear complexity over GF(r) of generalized cyclotomic quaternary sequences with period 2pq is determined, where r is an odd prime such that r ≥ 5 and r / ∈ {p, q}. The minimal value of the linear complexity is equal to 5pq+p+q+1 4 which is greater than the half of the period 2pq. According to the Berlekamp-Massey algorithm, these sequences are viewed as enough good for the u...
Introduction The left lateral Doruneh Fault System (DFS), is one of the longest, and most prominent, strike-slip faults in Iran, extending from the eastern border of Iran to the central Dasht-e-Kavir with a curved geometry. DFS is the response of the convergence between the Arabian and Eurasian plates in the regional tectonic map. Regarding to scaling relationships this fault with length of ...

Geological and geophysical studies in complex valley troughs provide a key record for the reconstruction of paleoenvironmental conditions during Quaternary. Here we present study sedimentary infill El Cervunal kame or trough (Sierra de Gredos, Iberian Central System) by means combined interpretation near-surface techniques supported geomorphological borehole data. A set 1D 2D methods, including...
In the title mol-ecule, C(27)H(24)N(2)O(2), the pyrrolidin-2-one ring is almost planar (r.m.s. deviation = 0.003 Å), the pyrrolidine ring has an envelope conformation (the N atom is the flap atom) and the cyclo-penta-none ring is twisted about the C(q)-C(m) bond (q = quaternary and m = methylene). The ketone O atoms are directed to opposite sides of the mol-ecule. Supra-molecular chains along t...
A divergent enantioselective approach to hapalindole-type alkaloids is described. The route features a ruthenium-catalyzed asymmetric hydrogenation of a ketone via DKR to construct the chiral trans-1indolyl-2-isopropenylcyclohexane skeleton and a switchable sequence of methylation and acetylation/ aldol reaction to access a chiral quaternary stereocenter. (+)-Hapalindole Q (1, 13 steps, 5.9% ov...
Two independent mol-ecules comprise the asymmetric unit in the title thio-carbamide derivative, C(10)H(13)NOS. These differ in the relative orientations of terminal ethyl groups [C-C-C-O torsion angles = -66.95 (13) and 55.92 (13)°, respectively]. The phenyl ring is twisted out of the plane of the central residue [C(q)-N-C(ph)-C(ph) = -146.20 (12) and -144.15 (12)°, respectively; q = quaternary...
The lowermost Mississippi River, defined herein as the river segment downstream of the Old River Control Structure and hydrodynamically influenced by the Gulf of Mexico, extends for approximately 500 km. This segment includes a bedrock (or more precisely, mixed bedrock-alluvial) reach that is bounded by an upstream alluvial-bedrock transition and a downstream bedrock-alluvial transition. Here w...
