The aim of the study was to create a hybrid forecasting method that could produce higher accuracy forecasts than previously used 'pure' time series methods. Mentioned methods were already tested with total automotive waste, hazardous automotive waste, and total medical waste generation, but demonstrated at least a 6% error rate in different cases and efforts were made to decrease it even more. Newly developed hybrid models used a random start generation method to incorporate different time-series advantages and it helped to increase the accuracy of forecasts by 3%-4% in hazardous automotive waste and total medical waste generation cases; the new model did not increase the accuracy of total automotive waste generation forecasts. Developed models' abilities to forecast short- and mid-term forecasts were tested using prediction horizon.

This study investigates the repurposing of asphaltene, a petroleum waste product, as a catalyst for organic reactions. Sulfonated asphaltene was synthesized and evaluated for its efficacy in catalyzing the Mannich reaction, displaying notable diastereoselectivity and operating effectively under mild conditions. Characterization of the catalyst's chemical composition, structure, and thermal stability was conducted using FT-IR, TGA, XRD, CHN, BET-BJH, SEM, and EDS analyses.

Introduction: Five million US Veterans had possible exposure to open burn pits used for waste disposal through service in Iraq (2003-2011) and Afghanistan (2001-2014). Burn pits generate toxic exposures that may be associated with adverse health outcomes. We examined all-cause and cause-specific mortality in relation to deployment to bases with open burn pits.

Food wasted in primary and secondary education institutions creates nutritional losses, financial inefficiencies, and environmental degradation. While there is some evidence of how particular interventions within schools may influence the amount of waste created, there is little recent information about typical levels of food waste generated in U.S.

Nanomaterial properties such as size, structure, and composition can be controlled by manipulating radiation, such as gamma rays, X-rays, and electron beams. This control allows scientists to create materials with desired properties that can be used in a wide range of applications, from electronics to medicine. This use of radiation for nanotechnology is revolutionizing the way we design and manufacture materials.
