This study deals with a methodical identification and evaluation of physical-mechanical properties of one genetic type of geological structure. This is represented by an engineering-geological zone of eolian sediments, which is regionally rather abundant. The paper contributes to a need to identify typical soil properties for widespread geological environments in a particular region and thus ad...

The theological parameters of a clay suspension can be used to evaluate particle-particle interactions. Although there have been many studies of the rheological behavior of suspensions of reference clays, only few studies were performed with suspensions of mixed clays, and the rheological properties of these suspensions are not yet fully understood. The length-to-width ratio of some soil clays ...

S-, a male child, four clays' old, was brought from a village to the Colvin Hospital, Allahabad, at about 6 o'clock on the evening of the 31st March, 1884. The hospital dhai came to me and reported that a baby had arrived in whom the natural passage of defecation was absent. I immediately went over to the hospital and saw it. The face was pinched ; the baby could cry only faintly, the breathing...

MiR-134 can function as an oncogene or a tumor suppressor gene depending on cell type. However, the function of miR-134 in gastric cancer remains unclear to date. This study aims to evaluate the function of miR-134 in gastric cancer and investigate its effect on the sensitivity of gastric cancer cells to 5-FU. The expression of miR-134 assayed by real-time PCR was significantly lower in gastric...

In order to make virtual modeling as easy as real clay manipulation, we describe a realtime virtual clay model, specially designed for direct hand manipulation. We build on a previous layered model for clay, extending it to handle local properties such as colour or fluidity, to deal with an arbitrary number of tools, and to capture twist effects due to rotating tools. The resulting clay model i...

Polymer/clay nanocomposites have been under an extensive investigation for about 15 years. Traditional methods to modify the clay are usually limited to small organic cations, preferably containing long alkyl chain(s), which are exchanged with the inorganic cations in the clay gallery. This article provides a comprehensive review on the strategies for clay modification using polymeric surfactan...

When woody plant abundance increases in grasslands and savannas, a phenomenon widely observed worldwide, there is considerable uncertainty as to whether aboveground net primary productivity (ANPP) and ecosystem carbon (C) and nitrogen (N) pools increase, decrease, or remain the same. We estimated ANPP and C and N pools in aboveground vegetation and surface soils on shallow clay and clay loam so...

Boom clay has been selected as a potential host rock formation for the geological disposal of radioactive waste in Belgium. In the present work, the hydro-mechanical behaviour of Boom clay samples from the borehole Essen-1 at a depth of 220-260 m and from HADES that is the underground rock laboratory at Mol in Belgium, at 223-m depth was investigated in the laboratory by performing low pressure...

A High Cation Exchange Capacity (HCM) montmorillonite clay has been prepared by acetate treatment of Zenith clay. The HCM has been evaluated for metal-uptake from aqueous solutions. The present data show that the cation exchange sites can play a significant role in the adsorption of metals in smectite clays. A theoretical analysis scheme has been developed which shows that permanent-charge site...
