The sustainable and competitive recovery of materials from spent batteries is becoming an urgent issue due to the increasing popularity hybrid fully electric vehicles. In this present study, flowsheet simulation was combined with life cycle assessment investigate environmental impacts a conceptual, experimentally proven hydrometallurgical battery recycling process, where nickel metal hydride (N...

The off-design performance of a combined cycle gas turbine (CCGT) plant for power generation is of great importance. In this work, a detailed mathematical model is developed for a triple-pressure reheat combined cycle power plant. Using the model, CCGT off-design operation and efficiency are studied under four gas turbine (GT) strategies. Controlling the turbine inlet temperature (TIT) gives be...

todays, improving the competitiveness of companies and rapidly responding to diverse customers’ demands requires efficient management of the supply chain. integration is one of the effective indices in a supply chain, and vendor managed inventory (vmi) is one of the innovative approaches in this field. in this paper, an integrated model based on a vmi system for deteriorating and ameliorating i...

The glaciation time of a mixed-phase cloud due to the Wegener–Bergeron–Findeisen mechanism is calculated using an adiabatic one-dimensional numerical model for the cases of zero, ascending, descending and oscillating vertical velocities. The characteristic values of the glaciation time are obtained for different concentrations of ice particles and liquid-water content. Steady state is not possi...

Previous studies have shown changes in women's behavior and physical appearance between the non-fertile and fertile phases of the menstrual cycle. It is assumed that these changes are regulated by fluctuations in sex hormone levels across the cycle. Receptors for sex hormones have been found on the vocal folds, suggesting a link between hormone levels and vocal fold function, which might cause ...

The Sodium-cooled fast reactor (SFR) features a closed fuel cycle for efficient conversion of fertile uranium and management of minor actinides. A full actinide-recycle fuel cycle is envisioned with two major options: One involves intermediatesized (150 to 500 MWe) sodium-cooled fast reactors with uranium-plutonium-minor-actinidezirconium metal alloy fuel, supported by a fuel cycle based on pyr...

The aim of this study was to correlate morphological changes in cells to known phases of the cell cycle. For this purpose, feline lymphoblastoid cells (FL74) chronically infected with feline leukemia virus were synchronized and examined by scanning and transmission electron microscopy. Scanning electron microscopy revealed that the cell surface underwent distinct changes which were found to be ...
