Wastewaters of several industries such as textile, leather or dye etc., contain dangerous and toxic compounds, even some which are potential carcinogenics. Considering the volume composition, wastewaters textile industry have much more polluting characteristics compared to other industries. Although treatment processes must definitely be implemented in point environment living organisms, many f...
Studies on recycled materials emerged during recent years. This paper investigates samples’ sound absorption properties for panels fabricated of a mixture sludge (PS) and clay mixture. PS was the core material. The measured. We also consider influence an air gap between rigid backing. Different gaps (50, 100, 150, 200 mm) simulate existing acoustic panel systems. Finally, composite coefficients...
Reflectance spectroscopy is a rapid and non-destructive method that can be used to detect organic compounds in geologic samples over a wide range of spatial scales that includes outcrops, hand samples, drill cores, and planetary surfaces. In order to assess the viability of this technique for quantification of organics and aliphatic compounds in particular, the present study examines how clay m...
Different types of sediments in salt marsh have different physical and chemical characters. Thus sediment type plays a role in plant competition and growth in salt marsh ecosystems. Spartina anglica populations have been increasingly confined to upper elevation gradients of clay, and the niche sediment has changed. Because the niches of S. anglica and the native species Scirpus triqueter overla...
Treatment of Clay with Oil Palm Fibre Ash and Rice Husk Ash Mixture for Burnt Clay Bricks Production
The current study examines the use of oil palm fibre ash (OPFA) and rice husk (RHA) mixture in treatment A-6 Makurdi clay for burnt brick production. results show that compressive strength 9.4 MN/m2 untreated increased to 10.86 2%OPFA+2%RHA treated brick. corresponding water absorption 14.9% 16.2% value is greater than 10.3 MN/m^2 which minimum negligible weather (NW) conditions. less 17%, 22% ...
This study was conducted to analyze the properties of deposit soil dredged from a reservoir which was processed for efficient treatment and management. Before starting this study, the physicochemical properties and the heavy metal content of the deposit soil were investigated to collect the fundamental data. In a treatment experiment proposed to use the deposit soil, the deposit soli was separa...
Most ice in nature forms because of impurities which boost the exceedingly low nucleation rate of pure supercooled water. However, the microscopic details of ice nucleation on these substances remain largely unknown. Here, we have unraveled the molecular mechanism and the kinetics of ice formation on kaolinite, a clay mineral playing a key role in climate science. We find that the formation of ...
