This study was conducted to determine long-term thermal regime of landfill liner systems using a field temperature monitoring program and numerical analysis of heat transfer. Temperatures in liner systems that contain geosynthetic clay liners (GCLs) were monitored prior and subsequent to waste placement. Data were collected in three cells at a landfill in Midwestern USA for more than five years...

Recently, biodigesters have attracted much attention as an efficient alternative for energy generation and organic waste treatment. The final performance of a biodigester depends heavily on the quality its building process selection raw material: geomembrane. geomembrane is coat that covers used to control migration fluids. Therefore, proper geomembrane, in terms thickness, resistance, flexibil...

Abstract Seawater is used to produce salt. For 10–15 years, geomembrane plastic has been in salt fields Indonesia prevent contamination and increase quality productivity. However, it unfortunate that currently, seawater polluted by waste, which degraded gradually into small pieces about <5 mm size called microplastics. In addition microplastics, also heavy metals. Previous research indicated...

Many women use panty liners between menstrual periods. The aim of this study was to investigate whether the use of such products might influence the vulva skin. Twelve healthy women were studied on four occasions with three different product constructions and on one occasion without products. Temperature, surface wetness and surface pH were measured on vulva skin. Mean skin temperature when the...

BACKGROUND AND AIM Thermal discomfort often affects prosthesis wearers and could be addressed by increasing liner thermal conductivity. This note explores a liner made from thermally conductive silicone and two additional alternative liner designs. TECHNIQUE Thermally conductive silicone was used to create a conductive liner and a hybrid liner. Additionally, one with open elements was made. T...
