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...

A predictive framework for flow liquefaction instabilities in sands is presented. A general criterion for liquefaction, based purely on the laws of physics, is presented and adapted to the important case of radial loading (e.g. triaxial, simple shear) using the Cambridge p9–q plane. Three important contributions are made in the paper. First, the instability concept is unified, and it is shown t...

AIM The most recent and innovative AquaLase liquefaction technology has offered an alternative to lens extraction. Many studies have investigated its functions and advantages. This article focuses on evaluating the in vivo microscopic cornea changes after AquaLase liquefaction by using a laser confocal microscope. METHODS In this perspective, randomized case study, 37 eyes of 35 patients subm...

The use of the shear wave velocity data as a field index for evaluating the liquefaction potential of sands is receiving increased attention because both shear wave velocity and liquefaction resistance are similarly influenced by many of the same factors such as void ratio, state of stress, stress history and geologic age. In this paper, the potential of support vector machines (SVM) based clas...

Regional-scale analyses of susceptibility to liquefaction are seldom performed in data-scarce areas. However, spite data limitations, such efforts can still provide useful information case populated, seismically active regions. The present work focuses on zonation for soil that might occur due ground shaking the Foggia Province, a data-scarce, area about 7000 km2 located southern Italy. Analyti...

The results of research on some aspects of coastal dynamics during earthquakes, carried out in the Institute of Hydro-Engineering, are summarized. The attention is focused on the liquefaction-related phenomena, like modeling the earthquake-induced generation of pore-pressures and subsequent liquefaction of subsoil, the behavior of liquefied soil, underwater landslides, sinking of structures in ...

Earthquake and its catastrophic failures has been one of the disturbance worry of Civil Engineers. In geotechnical science, liquefaction is one of the most important phenomenons induced by earthquake. A change in pore water pressure follows a change in effective stress, and in a critical state in which pore water pressure equals the total stress in soil particles, soil strength is suddenly lost...

Bachmann et al. (2005) contend that a major fraction of flocculent sediments, a ‘‘fluid mud layer,’’ which has accumulated in Lake Apopka, Florida, since 1947, originated from sediment liquefaction of consolidated macrophyte-derived sediments. In addition, they contend that the underlying historic sediments are not only a major source of fluid mud, but also the source of organic matter for inte...
