چکیده
as Fig. 1 in a slightly modified form. Green et at. note that the 1128 A transition is optically forbidden because it occurs between two even parity oxygen atom states, whereas the selection rules permit transitions between odd and even parity only (2). However, they do not say that the 79176 A (7.92 gum) transition is equally forbidden, as both relevant states are odd (3). It is also forbidden because of the restriction (for one

In vivo imaging of cellular proliferation in renal cell carcinoma using 18F-fluorothymidine PET
Objective(s): The ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. The aim of this study was to evaluate the uptake of 18Ffluorothymidine (FLT) PET in renal cell carcinoma (RCC), and to compare this to 18F-fluorodeoxyglucose (FDG), and to an immunohistochemical measure of cellular proliferatio...
متن کاملOptical Chirality Enhancement in Twisted Arrays of Plasmonic Nano-rods
An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...

متن کاملThe infrared spectrum of comet C / 1995 O 1 ( Hale - Bopp ) at 4 . 6 AU from the Sun ?
Comet C/1995 O1 (Hale-Bopp) was observed on 27 April 1996 with the ISOPHOT instrument of ISO when it was at 4.6 AU from the Sun. The 2.5–12 m spectrum was recorded at low resolution. We present here the preliminary results of this observation. The 2.5–5 m spectrum shows emission in the CO2 3 band. The CO2 production rate is about 1:3 1028 s 1. The 6–12 m spectrum shows thermal emission at a col...
