The wood biomass was liquefied by the pressurized hydrothermal method. The wood biomass powder in the different particle size, which was pulverized by a vibration mill, cutter mill and grinder, was used for the liquefaction. The liquefaction material was biomass slurry, which was prepared by mixing the wood biomass powder and water together (1:9). After filling the biomass slurry in a pressure ...

Strain wedge (SW) model formulation has been used, in previous work, to evaluate the response of a single pile or a group of piles (including its pile cap) in layered soils to lateral loading. The SW model approach provides appropriate prediction for the behavior of an isolated pile and pile group under lateral static loading in layered soil (sand and/or clay). The SW model analysis covers the ...

Purpose. Determination of partial posterior vitrectomy (PPV) in the proposed modification for treatment of malignant glaucoma. Methods. The prospective, consecutive, single-center case series study involved patients in whom symptoms of malignant glaucoma occurred after combined cataract and glaucoma surgery or after glaucoma surgery in pseudophakic eye. When medical and laser treatment were not...

purpose : to investigate the penetration of cefixime and ciprofloxacin to the rabbit eye on the basis of microbial inhibition of aqueous and vitreous humour after oral administration. methods : in this experimental study, 36 rabbits (72 eyes) were randomly divided into two groups group a consisted of 20 rabbits and group b 16 rabbits. each group was divided into four equal subgroups. the rabbit...

Third Graders’ Misconceptions about Evaporation and Liquefaction Phenomena A. Badriyaan, Ph.D. Concepts of evaporation and liquefaction are of significance in both daily life and the school curriculum, yet misconceptions about these two phenomena are frequent. To assess the extent of such misconceptions among third graders, a cluster sample of 132 of them from four schools i...

Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. As a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. In this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...

This paper presents prediction of liquefaction potential of soils by neuro-fuzzy models evaluated using Idriss and Boulanger method. In order to address the collective knowledge built up in conventional liquefaction method, an alternative Takagi-Sugeno-Kang reliant neuro-fuzzy model has been developed. Neuro-fuzzy is one of the artificial intelligence approaches that can be classified by machin...

Liquefaction is one of the most intriguing aspects of human tuberculosis. It is a major cause of the transition from the infection to active disease (tuberculosis, TB) as well as the transmission of M. tuberculosis to other persons. This paper reviews the natural history of liquefaction in humans from a pathological and radiological point of view and discusses how the experimental models availa...

To further clarify reasons for formation of condensed residues during the last stage of wood liquefaction in the medium of polyhydric alcohols and sulfuric acid catalyst, the weight loss behaviors and thermal reaction kinetics of condensed residues were studied by thermogravimetric analysis (TGA). Simultaneously, chemical methods were used to analyze the contents of lignin, cellulose, and holoc...

An empirical, energy-based methodology for liquefaction hazard assessment and microzonation mapping is presented. The approach is probabilistic, considers the uncertainty in the liquefaction criterion, and is applicable to most earthquake-induced liquefaction analyses. The examples illustrated are for water-saturated sands at level ground. The energy of ground shaking is estimated from the Four...
