Antibiotics in wastewater, sewage sludge, manures, and slurries constitute a risk for the environment when spread on soils. This work studies adsorption desorption of antibiotic cefuroxime (CFX) 23 agricultural forest soils, using batch-type experiments. Our results show that values were between 40.75 99.57% while range was lower (from 74.57 to 93.46%) Among Freundlich, Langmuir, Linear models,...

This paper demonstrates the application of a numerical methodology for a full-scale aircraft impact crashworthiness investigation. We studied the impact of an aircraft wing with a tree using LS-DYNA and ANSYS CFX. In particular, a detailed finite element model of the wing structure was represented as a box structure containing skin, spars and ribs, and fuel was represented as a distributed mass...

Butterfly valves are commonly used as control equipments in applications where the pressure drops required of the valves are relatively low. As shutoff valve (on/off service) or throttling valves (for flow or pressure control), the higher performance and the better precision of butterfly valves are required. Thus it’s more and more essential to know the flow characteristic around the valve. Due...

Lithium/carbon fluoride (Li/CFx) batteries have been widely researched due to their high theoretical specific energy. To create a high-performance electrode, the fluorinated hard carbon (FHC) is prepared by direct gas-phase fluorination. It has F/C ratio of 0.95 based on gravimetric method. Selecting (HC) with surface area as source allows for FHC achieve suitable interlayer spacing and area, w...
