For enveloping an object placed on a table, human often utilizes the wedge—effect where a simple pushing motion of the bottom part of object makes the object detach from the table. Through grasp experiments by human, we newly found an interesting behavior where human changes his (or her) finger posture from upright to crooked ones after all fingers make contact with the object. This motion is t...

Concerns about potential liquefaction and resulting flowslide type failures at Wickiup Dam in Central Oregon prompted geophysical studies of the left wing dike, studies which included a high resolution seismic reflection survey. High resolution seismic reflection data effectively delineated structures and correlated lithologies to shallow borehole data above the surface of the dipping, basalt b...

The method of preparing the distilled nutrient medium has been improved, thus rendering the cultivation of the bacillus leprae in this medium much more potent for the preparation of leprolin. Small pieces of pumice stone are washed and dried in the sun, and then made to absorb beef extract; they are then placed in bottles having a wide central tube leading to the bottom, aiuKin outlet tube at t...

The Bhumibol Dam on Ping River, Thailand, was constructed in 1964 to provide water for irrigation, hydroelectric power generation, flood mitigation, fisheries, and saltwater intrusion control the Great Chao Phraya River basin. Many studies, carried out near basin outlet, have suggested that dam impounds significant sediment, resulting shoreline retreat of Delta. In this study, impact damming se...

Several theoretical predictions of the mass flow rate of granular media discharged from a silo are based on the spontaneous development of a free-fall arch region, the existence of which is still controversial. In this Letter, we study experimentally and numerically the particle flow through an orifice placed at the bottom of 2D and 3D silos. The implementation of a coarse-grained technique all...

A new structure bulk tobacco curing barn was presented. To study the temperature and humidity field in the new structure tobacco curing barn, a 3D transient computational fluid dynamics (CFD) model was developed using porous medium, species transport, κ-ε turbulence and discrete phase models. The CFD results demonstrated that (1) the temperature and relative humidity predictions were validated ...

The value of biogas produced at small scale facilities, such as farm scale biogas plants, can increase by upgrading it to vehicle fuel quality. However, commercial upgrading technologies available today are very costly for small scale applications. Ash from combustion of wood fuels has a high content of Ca, which indicates favourable conditions for a high CO2 uptake capacity from biogas. The ob...

ABSTRACT Among several techniques for prevention and mitigation of reservoir sedimentation, bottom outlets arise as a means removing sediment deposited close to the dam. Given reduced removal provided by traditional under pressure flushing conditions, this article proposes new type structure that aims increase in direction parallel dam axis. An experimental installation was employed evaluate it...

Self-aerated flows in flat chutes are encountered downstream of the bottom outlet, spillways with a small slope and storm waterways. In present study, development self-aeration chute flow is described new experiments performed long pressure outlet for different discharge rates. The distribution air concentration, time mean velocity fluctuation direction self-aerated developing region—where bubb...
