To identify genes affected by single-walled carbon nanotubes (SWCNTs) in human normal lung cells, we compared the gene expression profiles of untreated human normal bronchial epithelial (HNBE) cells to profiles of HNBE cells treated with SWCNTs. A complementary DNA microarray analysis consisting of 54,675 human genes revealed marked changes in the(More)
In this paper a four-mirror tunable micro electro-mechanical systems (MEMS)Fabry Perot Interferometer (FPI) concept is proposed with the mathematical model. Thespectral range of the proposed FPI lies in the infrared spectrum ranging from 2400 to 4018(nm). FPI can be finely tuned by deflecting the two middle mirrors (or by changing the threecavity lengths).(More)
Partial/complete hydatidiform mole with coexisting fetus is a rare condition. Optimal management is a challenge that remains a dilemma since these pregnancies are associated with maternal as well as fetal complications including hemorrhage, preeclampsia, thromboembolic disease, intra uterine demise and increased risk of persistent trophoblastic disease.(More)
Iridian has just celebrated the tenth anniversary of its spin-off from the National Research Council of Canada. This article traces its evolution from a two-person start-up to a globally competitive manufacturing organization and illustrates some of the continuing technical achievements in optical thin film technology that underpinned this success. It(More)
