The seismic performance of four pile-supported models is studied for two conditions: (i) transient to full liquefaction condition, i.e. the phase when excess pore pressure gradually increases during the shaking; (ii) full liquefaction condition, i.e. defined as the state where the seismically induced excess pore pressure equalises to the overburden stress. The paper describes two complementary ...

Liquefaction is one of the most determinant factors in the collapse of transportation infrastructures. This is especially true for roads and railroads located on saturated, fine-sand substrates under seismic conditions. The damage and human casualties resulting from liquefaction highlight the importance of understanding and mapping this phenomenon. Soil liquefaction occurs as a natural hazard i...

Liquefaction has been responsible for several earthquake-related hazards in the past. An earthquake may cause liquefaction saturated granular soils, which might lead to massive consequences. The ability accurately anticipate soil potential is thus critical, particularly context of civil engineering project planning. Support vector machines (SVMs) and Bayesian optimization (BO), a well-known met...

Semen analysis of 66 unmarried medical students in the age group of 17-21 years was carried out. A higher liquefaction time pH, motility, lower sperm count and abnormal forms were observed compared to reported values. Liquefaction time, pH and sperm count was found significantly different in non-vegetarians and vegetarians, perhaps due to difference in their dietary proteins.

Herein, the data acquired regarding the preliminary experiments conducted with different catalyst, as well as with two polyhydric alcohols (glycerol and 2-ethylhexanol), for the preparation biooils from cork liquefaction at 160 °C, is disclosed. This data may be helpful for those who intent to outline a liquefaction procedure avoiding, thus, high number of experiments.

A process is described for converting aflatoxin-contaminated corn to ethanol via combining ammonia inactivation with the liquefaction step of the ethanol fermentation process. Better ethanol yields were obtained when ammonia was added during liquefaction than when no ammonia was added. Aflatoxin B1 levels were reduced 80 to 85% by the process.

Official Seismic Hazard Zone Maps of Dublin, Livermore, and Altamont 7.5-minute quadrangles (1:24,000 scale) show areas that may be susceptible to earthquake-induced liquefaction. The maps are the result of the three-dimensional integration of geotechnical and geological data. Approximately 450 geotechnical borehole logs were collected, analyzed, entered into a geotechnical Geographic Informati...

Black liquor alkaline lignin and magnesium lignosulfonate were liquefied at 320 C. The antioxidant abilities of the liquefaction products were compared with the raw materials. Results showed that the total phenol content and unit antioxidant power of both alkaline lignin liquefaction products (ALLP) and magnesium lignosulfonate liquefaction products (MLLP) were improved, and ALLP had a larger i...

Objective: Human semen is the jelly-like substance mainly containing semenogelin 1 (Sg1) and fibronectin (Fn) with the characteristics of coagulation and liquefaction in a short time. In our previous study, we have identified that Eppin could interact with Sg. Eppin C-terminal fragment bind the Sg fragment containing the only cysteine in human Sg I (Cys-239). Besides that, during semen liquefac...

Multiple occurrences of liquefaction in recent earthquake events revealed the importance studying reliquefaction characteristics sandy soils. However, there is a lack knowledge determining dynamic properties reliquefied Through series hollow cylinder torsional shear tests, this paper presents first-hand experimental study to investigate modulus reduction and damping Toyoura sand under integrate...
