The success of stem cell application in regenerative medicine, usually require a stable source of stem or progenitor cells. Fat tissue represents a good source of stem cells because it is rich in stem cells and there are fewer ethical issues related to the use of such stem cells, unlike embryonic stem cells. Therefore, there has been increased interest in adipose-derived stem cells (ADSCs) for tissue...
Insulation material for power systems subjected to long-tern operation may deteriorate because of various reasons. If equipment are poorly maintained, the power system may collapse and cause blackouts. To protect high-voltage power system equipment, identifying and analyzing the partial discharge phenomenon caused by insulation deterioration has become an important approach for preventive fault diagnosis...
A new ion chromatography coupled with tandem mass spectrometry (IC-ESI-MS/MS) method, with automated sampling and on-line preconcentration, has been developed for the determination of perchlorate in Antarctic snow and ice at low part-per-trillion (ng/L) levels. To the best of our knowledge, this is the first time that an analytical method is used for the determination of perchlorate in Antarctic snow...
