Background: Consumer behaviors at the household level have an impact on the quantity of food waste and the economic resources of the family and the country. This study aimed to assess food waste in a random sample of the Libyan community. Methods: A questionnaire was designed for the study and distributed randomly through social media, short message, e-mails, and via face to face interviews ...
Introduction: We are conducting a survey of the emission spectra of 27 class M asteroids using the Spitzer Infrared Spec-trgraph (IRS; 5.2–38 µm). Although the visible and near-IR spectra of these asteroids are nearly featureless, ten of these asteroids are now known to have hydration features at 3 µm that are absent in the spectra of 15 others [1]. High S/N spectroscopy of these asteroids in t...
A superconducting permanent magnet system capable of generating strong magnetic fields has been constructed by using bulk high temperatures superconductors HTS. The magnetic field in the open space between the facetoface settled magnetic poles has exceeded 3 T when they were activated at 30 K. We have investigated the magnetic separation technique with respect to Fe ions in the waste water dr...
Ground green waste is used as mulch in ornamental landscapes and for tree crops such as avocados. Survival of Armillaria mellea, Phytophthora cinnamomi, Sclerotinia sclerotiorum, and Tylenchulus semipenetrans was assessed for 8 weeks within unturned piles of either recently ground or partially composted green waste. S. sclerotiorum survived at the pile surface and at 10, 30, and 100 cm within t...
Human exposure to pollutants from e-waste is an important scientific issue for their health effects. In this study, organohalogen pollutants in human serum sample from an e-waste dismantling site (n=35) and a control site (n=21), both located in Tianjin, Northern China, were analyzed using GC-ECNI-MS. Geometric mean concentrations of tetra- through hexa-BDEs, hepta- through nona-BDEs, PCBs, PBB...
