The construction of toll roads in South Sumatra faces two problems. First, most the road sections are built on soft soil deposits, so must be improved to speed up consolidation process and improve bearing capacity. Second, embankment required reach design elevation is quite high that reinforcement needed slope stability. This paper contains results a study effect improvement using PVD vacuum pr...

Using two biological characteristics of the land snail (subspecies Helix aspersa aspersa and Helix aspersa maxima), i.e., soil eating and crawling on wet surfaces, methods were developed to assess the bioavailability of heavy metals (Cd, Cr, Pb, and Zn) from soil and aqueous leachates of soil. Measurement of heavy-metal concentrations in soil, leachates, and soft tissues of snails showed that c...

At the peak of the Vietnam War, the network of tunnels in the Iron Triangle and Cu Chi linked Viet Cong (VC) support bases over a distance of some 250 km, from the Ho Chi Minh Trail and Cambodian border to the outskirts Saigon. In the early 1960s, the United States escalated its military presence in Vietnam in support of a non-Communist regime in South Vietnam. The North Vietnamese and VC troop...

The techniques of data mining are very popular in the area of agriculture. The advancement in Agricultural research has been improved by technical advances in computation, automation and data mining. Now a days ,data mining is being used in a vast areas .The products of data mining system and domain specific data mining application soft ware’s are available for tailor made use, but data mining ...

The construction process of pile foundations can significantly disrupt the soil. Therefore, it is necessary to limit degree soil disturbance caused by foundation an acceptable level. This paper examines effects driving on soft foundations, specifically analyzing squeezing effect squeezed piles and unloading non-squeezed piles. To investigate these effects, two typical piles, a hydrostatic pile,...

A series of 10 aircraft flights was conducted over agricultural fields to evaluate relationships between observed surface soil moisture and soft moisture predicted using passive microwave sensor observations. An a pr/or/ approach was used to predict values of surface soil moisture for three types of fields: tilled corn, no-till corn with soybean stubble, and idle fields with corn stubble. Accep...

The base level is among the effective parameters in determining the seismic force on a structure, if the equivalent-static method is used for analyzing a structure. It is obvious that the base level is located on foundation in buildings in which foundation is built in a single level and there is not any interaction between the structure's walls and the soil; however, in some buildings which hav...
