The influences of the pin geometry and rotational speed on the microstructure evolution and mechanical properties of the AA 5052-H112 FSSW joint were investigated.Results showed that hook height and fully bonded region (FBR) width were significantly dependent by both pin geometry and rotational speeds.Both pin geometry and FIBER POMADE tool rotatio
Nitrate concentration in groundwater has frequently been linked to non-point pollution.At the same time the existence of intensive agriculture and extremely intensive livestock activity increases the potential for nitrate pollution in shallow groundwater.Nitrate used in agriculture could cause adverse effects on human and animal health.In order to
Positive developmental consequences for home-based enterprises (HBEs) are diminished in South African townships, due to insufficient alignment of business support interventions (BSI).There is limited urban planning knowledge on how HBEs in townships operate within residential zones and how spatial and regulatory challenges affect their development.
The aim was the evaluation of IL-6 concentration in peritoneal lavage fluid of children which underwent cholecystectomy to ascertain if there is a difference in early inflammatory response depending on the type of surgical approach (open vs.laparoscopy).The analysis of high-mobility group protein B1 (HMGB1) and heat shock protein 70 (HSP70) was per
