While contributions to the digital commons of Free/Libre Open Source Software (FLOSS) communities, such as source code and documentation, have been widely explored, other types of contribution have remained less visible. This paper offers empirical evidence of the perception of “community-oriented” activities as contributions, their lack of visibility in digital collaboration platforms, and the...

the aim of the study is to determine the major source and extent of metal pollution in the vicinity of dashkasan gold mine. dashkasan mine has resulted in extensive contamination of soils by arsenic (as) and potentially toxic ore-related elements including mercury (hg), antimony (sb) and cadmium (cd). soils samples were collected and analyzed for as, cd, hg, pb and sb. the concentration of each...

objective(s): abdominal adhesions are one of the most important problems, occurring after intra-abdominal surgery in more than 90% of cases. this condition is the leading cause of bowel obstruction, infertility, and abdominal/pelvic pain. gold nanoparticles (gnps) have been shown to be non-toxic and exhibit anti-inflammatory, anti-angiogenic and antioxidant activities. the purpose of this study...
