reduction of U(VI) sorbed to
synthetic Fe(3) oxides and highly Fe(3) oxide-enriched
natural materials
U(VI) reduction was generally slower and less extensive in the presence of natural soil or sediment materials
☞ Compared to more Fe-rich materials.
Comparison with heat-killed systems indicated that continued reduction of U(VI) in the live systems
☞ Ongoing DMRB activity
1. SVE(soil vapor extraction-in situ)
1) principle
Soil vapor extraction, also known as soil
venting or vacuum extraction, is a cleanup
technology commonly used to remove
VOCs in vapor from contaminated property.
4) Application
Contaminant : VOCs
Place : gas station base, industrial base,
military base
Layer : contaminated

This project purpose is analyzing and comparing FS of slope between the numerical analysis program and values using expressions are suggested by another researchers, and understanding influenced factors of slope safety. Given problem is in a state of ground water level in ground divided upper and lower layers. Using numerical analysis program, we study how ground water level will be affecting t
Many factors, such as the way to experiment shear strength, the choice of shear strength, the way to analyze, the characteristic of shear strength, slope‘s geometrical condition and the degree of uncertainty of other conditions, the cost spent to lower slope’s slope or to decrease the height, the result and the amount of damage when slope is destructed, judging whether slope is the permanent

1)회사개요
가. 설립과 발전
S-Oil은 1970년대 두차례에 걸친 석유파동의 위기속에서 원유의 안정적 확보와 석유제품의 원활한 공급이 절실했던 당시의 시대적 요구에 부응하여 1976년 설립되었습니다. S-Oil은 울산광역시 공단 내에 40만평의 부지를 조성, 건설공사에 착수하여
제한효소나 PCR을 할 수 있게 해준 Taq polymerase가 그 예이다. 이에 따라 많은 생물학자들이 미생물의 연구로부터 미생물의 유용물질을 연구하고 있다. 따라서 우리는 이러한 미생물을 연구하기 위해서 특정 지역(우리는 대한민국 서울 연세대학교의 연세 역사의 뜰(Figure 1))에서 Soil을 채취해 왔다.
soil dust, road dust, gasoline vehicle emissions, diesel vehicle emissions, point, municipal incinerator, coal-fired power, biomass burning and marine emissions. As a result, vehicle emissions were the largest contributor during this period and averaged approximately 50% of the PM2.5 mass.
