The effect of high temperature annealing of the InAs/ InP quantum dots QDs containing a thin GaAs interlayer is investigated. The QDs are rapid thermally annealed at 750, 800, 850, and 900 °C for 30 s. The QDs with the GaAs interlayer show good thermal stability up to 850 °C as well as enhanced integrated photoluminescence PL intensity and reduced PL linewidth. The effect of high energy 450 keV...
BACKGROUND Epidural clonidine produces analgesia without motor impairment, and is associated with a local anesthetic-sparing effect during labor. The authors have recently demonstrated that epidural neostigmine initiates selective labor analgesia devoid of adverse effects. Both drugs possess common analgesic mechanisms mediated through spinal acetylcholine release. This study evaluates their ep...
Rural residents can be exposed to agricultural pesticides through the proximity of their homes to crop fields. Previously, we developed a method to create historical crop maps using a geographic information system. The aim of the present study was to determine whether crop maps are useful for predicting levels of crop herbicides in carpet dust samples from residences. From homes of participants...
