It is difficult to determine the coefficient of restitution accurately due small size, light weight, and complex influencing factors rice grain. In study, experimental principle was described by impact method, coefficients four typical varieties in Northeast China were measured. According orthogonal experiment, primary secondary affecting grain collision material, spring compression (initial ve...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

This contribution investigates the role of a hyperextended rift system in formation Basque–Cantabrian Pyrenees by discussing their present-day architecture as well inherited template. Moreover, this work attempts to decipher onset reactivation and discuss related processes during collision. To carry out study, two regional, crustal-scale cross-sections are presented that provide geological geop...

using global free air gravity and topography data, first we have calculated a bouguer anomaly (ba) map for iranian plateau and then computed the residual isostasy anomaly map under the airy-heiskannen assumption. the term residual is used as to reflect the assumption of local isostatic compensation in contrast to a regional isostatic compensation. the value with which the gravity effect of the ...

The occurrence of plate tectonic processes on Earth during the Paleoproterozoic is supported by ca. 2.2–1.8 Ga subduction-collision orogens associated with assembly Columbia-Nuna supercontinent. Subsequent supercontinent breakup evidence global 1.8–1.6 large igneous provinces. North China craton notable for containing along its margins, herein named Northern Margin orogen, yet nature and timing...

Collision between the Pontides and Anatolide-Tauride Block along İzmir-Ankara-Erzincan suture in Anatolia has been variously estimated from Late Cretaceous to Eocene. It remains unclear whether this age range results a protracted, multi-phase collision or differences proxies of and/or strike diachroneity. Here, we leverage Cretaceous-Eocene evolution forearc-to-foreland Central Sakarya Basin sy...

The Sanjiang Tethyan Metallogenic Domain refers to the Hengduan Mountain Range where Nujiang River, Lancang River and Jinsha run side by side, spanning western Yunnan, Sichuan, eastern Tibet southern Qinghai, including Qinghai-Tibet Plateau Yunnan-Guizhou Plateau, with an area of about 50 × 104 km2. range belongs part global Tethys-Himalayan Tectonic structurally, which is in region Gondwana Eu...

Abstract The closure of a subduction zone with continental terrane collision and accretion is generally thought to be followed by the initiation new in neighboring oceanic plate, which suggested happen repeatedly during evolution Tethyan system. Although Indian‐Asian has occurred for >50 Myrs, there still no clear sign (SI) northern Indian puzzling issue requires further investigations. This...

Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...
