Electron phase space holes (EHs) associated with electron trapping are commonly observed as bipolar electric field signatures in both and laboratory plasma. Until recently, it has not been possible to resolve EHs measurements. We report observations of the plasma sheet boundary layer, here identified separatrix region magnetic reconnection magnetotail. The intense together an beam moving toward...

  The effects of gentamicin, lithium and combination of these drugs on ultrastructural morphology of rat submandibular glands were studied. Daily intraperitoneal injection of 40 mg/kg of gentamicin which causes chronic salivary gland toxicity, led to a marked decrease in gland's dry weight and total protein concentration but did not affect DNA content. Electron micrograph (EM) of submandibular ...
