Dislocation density and graphitization of diamond crystals [PDF]

open access: yes, 2002
Two sets of diamond specimens compressed at 2 GPa at temperatures varying between 1060 K and 1760 K were prepared; one in which graphitization was promoted by the presence of water and another in which graphitization of diamond was practically absent.

Exposure Registries as a Prevention Tool for Occupational Cancers: Establishing a New Hazardous Drug Registry for Oncology Personnel

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Public health registries collect and maintain demographic and health data on a cohort of people with a common disease or exposure. While disease registries have proliferated in recent decades, registries comprising persons with potentially hazardous exposures—known commonly as exposure registries—are rare.

Development of a Green Capillary Electrophoresis Method for Determining and Quality Control of Dapagliflozin: An Oral Hypoglycemic Agent

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT A green method by capillary electrophoresis (CE) is described for the first time for the determination of dapagliflozin (DAPA), an oral hypoglycemic drug approved for the treatment of Type 2 diabetes mellitus. The effects of different analytical conditions were evaluated, including the concentration and pH of the background electrolyte (BGE ...
