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...

The simplest water diversion method in irrigation systems is using intakes. Measuring the mean velocity is one of the essential hydraulic parameters in increasing the efficiency of the intake. In this study, the mean velocity was predicted for different width ratios of an intake using ANN-MLP neural network model. In order to do that, the flow field within a 90-degree intake was first simulated...

Several effective methods have been developed recently to demonstrate simultaneous high energy and power density in Lithium - carbon fluoride (Li-CFx) batteries. These can achieve as a 1000 Wh/kg at 60–70 kW/kg (40–50 C rate) coin cells 750 12.5 (20 pouch cells. This performance is made possible by an ingenious nano-architecture design, controlled porosity, boron doping, electrolyte additives. ...

Lithium-fluorinated carbon (Li-CFx) batteries have become one of the most widely applied power sources for high energy density applications because advantages provided by CFx cathode. Moreover, large gap between practical and theoretical potentials alongside stoichiometric limit commercial graphite fluorides indicates potential further improvement. Herein, monolayer fluorinated graphene nanorib...
