Widespread Pesticide Distribution in the European Atmosphere Questions their Degradability in Air.

Risk assessment of pesticide impacts on remote ecosystems makes use of model-estimated degradation in air. Recent studies suggest these degradation rates to be overestimated, questioning current pesticide regulation. Here, we investigated the concentrations of 76 pesticides in Europe at 29 rural, coastal, mountain, and polar sites during the agricultural application season.

Long-term observations of the background aerosol at Cabauw, The Netherlands.

Long-term measurements of PM mass concentrations and aerosol particle size distributions from 2008 to 2015, as well as hygroscopicity measurements conducted over one year (2008-2009) at Cabauw, The Netherlands, are compiled here in order to provide a comprehensive dataset for understanding the trends and annual variabilities of the atmospheric aerosol in the region. PM concentrations have a mean value of 14.4μgm with standard deviation 2.

Predictable provisionalization: achieving psychological satisfaction, form, and function.

Unlabelled: The dentition is the foundation of the human face and is far more than just a masticatory apparatus. The smile, which is the definition of humankind, crosses all gender, age, cultural, and religious boundaries to express emotion. When enhancing or restoring a smile with aesthetic dentistry, the provisionalization phase is critical in conveying information regarding function, occlusion, phonetics, and the patient's expectations among the members of the restorative team.

Enhancement of the antitumor-activity of Corynebacterium parvum by appropriate adjustment of dosage schedules.

Single and multiple doses of Corynebacterium parvum ranging from 0.01 to 60 mg/kg as the total dose were tested at selected times against 10(6) P388 leukemia cells inoculated ip in BDF1 mice. The minimum dose needed for maximum protection was determined according to the ability of the treatment to produce an increase in the lifespan (ILS) of mice.

Optimal conditions for antitumor activity of C. parvum against the ascites form of sarcoma 180.

Single and multiple doses of Corynebacterium parvum (C. parvum) ranging from 0.1--60 mg/kg were tested for antitumor activity against 10(6) sarcoma 180 cells in male CD1 mice.
