This study investigates the load sharing capabilities for half-caps of a 190m long timber bridge. The bridge has 31 spans over the Avon River in Toodyay, Western Australia. It was constructed from local hardwood timbers and had a series of repairs. However as the width between kerbs was only 5.5 m and it was no footpath it was decided to replace the bridge by a new wider concrete structure. The...

OBJECTIVE The aim of the study is to evaluate the stress distribution in tooth supported 5-unit fixed partial denture (FPD) having tooth as pier abutment using rigid and nonrigid connectors respectively, under simultaneous and progressive loading. MATERIAL AND METHODS The three-dimensional (3D) finite element program (ANSYS software) was used to construct the mathematical model. Two 5-unit FP...

Grafting is a method of asexual plant propagation that joins plant parts for them to live together. So they will grow as one plant. Normally the method has been largely applied to propagate trees that will not root well as cuttings or whose own root systems are not strong enough or resistant to several soil-borne pathogens. Now the method is used for other crops, as vegetables, such as solanace...

Viruses are the most common causes of diseases affecting cucurbits in New York. These diseases result in losses through reduction in growth and yield and are responsible for distortion and mottling of fruit , making the product unmarketable. A complex of viruses is able to infect cucurbits, a plant group that includes cucumber , melon , squash, pumpkins , and watermelon. The most important viru...

Abstract The appearance of an ice jam in a river crucially distorts local hydrodynamic conditions including water level, flow velocity, riverbed form and scour processes. Laboratory experiments are used for the first time here to study ice-induced processes near bridge pier. Results show that with sheet cover hole depth around is increased by about 10% compared under equivalent open conditions....

Because of the problem local scour caused by change flow structure water-resistance column bridge pier, theoretical analysis, and indoor water tank test were used to study effect installing a new anti-scouring device in front pier on reduction effect; influence main design parameters such as height protective device, angle distance from was selected, optimal parameter combination selected. The ...

In a laterally asymmetric intake pumping station, the flow direction in forebay is not consistent with channel. Thus, adverse patterns, such as bias flow, large-scale vortex and occur frequently sump. Based on Reynolds-averaged Navier-Stokes (RANS) equation RNG k-ε turbulence model, recent pattern station was numerically simulated analyzed, effective elimination measures were proposed. For orig...
