Understanding the effect of underground excavations and barrier capability near field are relevant to geologic disposal nuclear waste. For a repository in crystalline host rock characterization naturally fractured excavated disturbed zone importance study migration radionuclides. Excavations could weaken components that part engineered system. Permeable zones also develop around walls create co...

Most food waste is incinerated and reclaimed in Korea. Due to the development of industry, soil groundwater pollution are serious. The purpose this study was recycled materials eco-friendly remediation methods prevent secondary after remediation. In study, ash filled a permeable reactive barrier (PRB) used as heavy metal adsorption material. situ electrokinetic techniques (EK) acetic acid were ...

The method is cheap and quick. Due to lowering the temperature of solution's glass transition the permeable cryoprotectants prevents the actual freezing of solution and allows to maintain its some flexibility in a glassy phase. Vitrification without permeable cryoprotectants allows to avoid the cryoprotectants toxicity and osmotic stress; the damage of plasmatic and mitochondrial membrane durin...

In order to increase the reuse of wastes and residues, as required by Waste Framework Directive, potential use waste, residue natural minerals low-cost permeable reactive barrier (PRB) materials was investigated. The performance a kitchen waste compost, sepiolite steel slag compared with that volcanic slag, pumice activated carbon in removing specific contaminants from landfill leachate. experi...

Nitrate in drinking water is a hazard to both humans and animals. Contaminated water can cause methemoglobinemia and may pose a cancer risk. Permeable barriers containing innocuous oils, which stimulate denitrification, can remove nitrate from flowing groundwater. For this study, a sand tank (1.1 x 2.0 x 0.085 m in size) containing sand was used as a one-dimensional open-top scale model of an a...

The effect of super atmospheric O2 and modified atmosphere packaging (MAP) on plant metabolism, organoleptic quality and microbial growth of minimally processed baby spinach was studied. Packaging film O2 transmission rates and initial levels of super atmospheric O2 in the packages significantly affected the changes of in-package atmospheres during storage, and consequently quality of baby spin...
