In recent years, the removal of dyes has emerged as a significant problem that attracted several researchers. The search for green and eco-friendly adsorbents been never-ending task in environmental protection to overcome this issue. Herein, almond shells (AS) were used an adsorbent remove methyl orange (MO) from aqueous solutions. AS was characterized using techniques such X-ray diffraction (X...
This study investigates the flotation performance of a representative hard coal slime sample (d80 particle size of minus 0.2 mm) obtained from the Prosper-Haniel coal preparation plant located in Bottrop, Germany. Flotation was carried out with a newly designed flotation cell refurbished from an old ultrasonic cleaning bath (2.5 L volume) equipped with a single frequency (35 kHz) and two differ...
Exploitation of fossil fuels such as lignite, brown coal, crude oil and natural gas comes from the oxidation of carbon stored over millions of years in the Earth’s crust; the combustible energy when released in the atmosphere emits carbon dioxide (CO2). Increased concentration of CO2 in the atmosphere causes global warming, because it is a greenhouse gas. Fossil fuels are limited and concentrat...
Dust explosions always claim lives and cause huge financial losses. Dust explosion risk can be prevented by inherently safer design or mitigated by engineering protective system. Design of explosion prevention and protection needs comprehensive knowledge and data on the process, workshop, equipment, and combustible materials. The knowledge includes standards, expertise of experts, and practical...
Clinical studies indicate that smoking combustible cigarettes promotes progression of renal and cardiac injury, leading to functional decline in the setting of chronic kidney disease (CKD). However, basic studies using in vivo small animal models that mimic clinical pathology of CKD are lacking. To address this issue, we evaluated renal and cardiac injury progression and functional changes indu...
We describe an algorithm for the analysis of color images of basins which gather dirty water, with the objective of detecting and estimate the presence of exceeding combustible oil. The algorithm first detects most of the pixel corresponding to the combustible oil applying a thresholding method based on the entropy of the image’s histogram. Then it treats the images differently according to the...
Abstract Biomass gasification is a thermochemical conversion process of solid biomass into gaseous fuel called producer gas that can be used to generate power and electricity. The consists around 47% Nitrogen (N 2 ), 24% Carbon Monoxide (CO), 16% Dioxide (CO 12% Hydrogen (H 1% Methane (CH 4 ). However, ) content in the reduces its heating values as N acts diluent because low calorific value (LC...
