In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

ten solanum tuberosum cultivars and accessions from 11 wild solanum species were evaluated for their tolerance to salt (200 mm nacl or 100 mm na2so4), drought (35% peg), cold (-4ºc) and heat (37ºc). evaluation was based on electrolyte leakage from de-tached leaves of in vitro plantlets. testing involved a rinsing treatment with three changes of distilled water to remove electrolytes from leaf a...

in the traditional hole drilling method the in-plane stresses are studied in detail and the interlaminar stresses are not taken seriously. the interlaminar stresses on the free edge of composite materials are important and can cause matrix cracking and delamination. inserting holes in composite laminates causes free edges and it can induce interlaminar shear and normal stresses. in this researc...

The increasing calls for decarbonization, and the consequent need energy system to integrate ever-increasing shares of renewable energy, place electric grid at core an integrated, decarbonized system. This Transmission System Operators (TSOs) Distribution (DSOs) fast-track integration clean solutions into [1]–[3]. In this framework, whatever new management/business models can be envisaged moder...

indoor radon and thoron have been measured in the houses ofmoradabad district, uttar pradesh india, by means of solid state nuclear trackdetectors. radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. radon exists in soil gas building materials and indooratmosphere to name but a f...

BTB (broad-complex, tram track and bric-a-brac) proteins have broad functions in different growth processes biotic abiotic stresses. However, the biological role of these has not yet been explored grapevine, which draws our attention towards gene family. Herein, we identified 69 genes (VvBTB) Vitis vinifera genome performed comprehensive silico analysis. Phylogenetic analysis classified VvBTB i...

Higher train speeds and heavier axle loads trigger elevated stresses vibrations in the track, potentially increasing track deterioration rates maintenance costs. Alternative forms made of combinations reinforced concrete asphalt layers have been developed. A thorough understanding slab tracks is needed to investigate performance. Thus, analytical numerical models developed validated by many res...
