A supercapacitor is an energy-storage device able to store and release energy at fast rates with extended cycle life; thus, it used in various electrical appliances. Carbon materials prepared above 800 °C of activation temperatures are generally employed as electrode material for supercapacitors. Herein, we report carbon from a low-cost petroleum waste precursor that was activated using KOH, Mg...

background: dental waste can be hazardous to humans and the environment. objective: to determine the current status of dental waste management in private and public dental clinics and private dental offices in shiraz, southern iran. methods: this cross-sectional study was conducted at the shiraz university of medical sciences from february through june 2013. a stratified random sampling method ...

The problem of utilization of high-activity waste by effect of nuclear transmutation in growing associations of microbiological cultures was studied. For the first time we have observed utilization of several kinds of highly active isotopes in the volume of distilled water extracted from the first contour of water-water atomic reactor convert to non-radioactive nuclei. 1. The model and the foun...

Recent studies have shown the potential of food waste materials as low cost adsorbents for the removal of heavy metals and toxic elements from wastewater. However, the adsorption experiments have been performed in heterogeneous conditions, consequently it is difficult to compare the efficiency of the individual adsorbents. In this study, the adsorption capacities of 12 food waste materials were...

In this study, waste water drains and produced phosphate fertilizers of conventional wet-process (hemihydrate) phosphoric acid and phosphate fertilizer plants were investigated to determine the average uranium contents in the active manufacturing period. The method chosen for the determination of uranium was an extension of an existing spectroanalytical method and was adopted for waste water an...

Dynacargo is an ongoing research project that introduces a breakthrough approach for cargo management systems, as it places the hauled cargos in the center of a haulage information management system, instead of the vehicle. Dynacargo attempts to manage both distribution and collection processes, providing an integrated approach. This paper presents the Dynacargo architectural modules and interr...
