The microwave liquefaction kinetics of corn stover in the presence of ethylene glycol (EG) using sulfuric acid as a catalyst was studied. The liquefaction apparent rate constant (k) was examined using a first-order reaction model. The k values of corn stover increased from 0.080 min -1 to 0.165 min -1 , with the reaction temperature increasing from 120 o C to 180 o C. The k value of cellulose a...

PURPOSE To investigate the effect of lens density on liquefaction time by using liquefaction device (AquaLase, Alcon Laboratories, TX, U.S.A.). METHODS Cataract surgery using AquaLase was performed on 47 eyes. With a Scheimpflug camera, the density and thickness of lens were measured in eye of each patient preoperatively. During surgery, liquefaction time and total number of pulses were recor...

A process was explored for continuous enzymatic liquefaction of corn starch at high concentration and subsequently saccharification to glucose. The process appears to be quite efficient for conversion of starch to glucose and enzymatic liquefaction and should be readily adaptable to industrial fermentation processes. Preliminary work indicated that milled corn or other cereal grains also can be...

The potential for liquefaction triggering of a soil under a given seismic loading is measured herein by probability of liquefaction. The first order reliability method FORM is used to calculate reliability index, from which the probability of liquefaction is obtained. This approach requires the knowledge of parameter and model uncertainties; the latter is the focus of this paper. An empirical m...

Earthquake induced liquefaction in saturated granular soils is an important phenomenon causing severe damages. In order to minimize the ill-effects due to liquefaction, various lab tests, field tests are being used which assess the liquefaction potential. In the present study the shake table test has been used for assessing soil liquefaction of loose saturated cohesionless sand by simulating ea...

This study is an attempt to investigate the effect of the nano-kaolinite concentration on the liquefaction resistance of liquefiable sand from Gorgan city of Iran. To examine the influence of the nano-kaolinite concentration on the liquefaction resistance of nano-kaolinite-sand mixtures, three different nano-kaolinite concentrations: 3%, 6% and 9% were prepared. Cyclic triaxial tests were condu...

As one of the significant phenomena in earthquake geotechnical engineering, liquefaction can cause severe damages. A number of factors play a role in the occurrence of liquefaction such as magnitude of earthquake, void ratio, relative density, and fines content percentage. The impact of building construction overburdens on liquefaction is of paramount importance. The present study was aimed at ...

Abstract The Kretek 2 Bridge is one of the important infrastructures built on southern coast road Java. Referring to Map Indonesia Liquefaction Vulnerability Zone in 2019, was identified as a high liquefaction susceptibility zone. result potential analysis slab-on-pile section indicates that soil layer has liquefy if an earthquake occurs. Based Severity Index, severity index at BH-10, moderate ...

The parts of Yogyakarta-Bawen Toll Road Indonesia, based on the geological agency’s liquefaction susceptibility map are located moderately susceptible to soil. This can be a preliminary indication as it roughly indicate potential. However, cannot illustrate actual condition in detail its inputs macro parameters (geological and seismicity factors). existence silty sand sand, earthquake sources, ...
