Electrical Engineering, 1954
PREPARATORY WORK and preliminary design on an air switch to meet the 330-kv American Gas and Electric system requirements began several years ago while the general insulation problem of the system was being studied. After the 1,300-kv level, a stack of insulators seven high was selected for the switch; many preliminary tests were made on the stack ...

The FlexiGard®330 ICC, an ultrasound evaluation
Contraception, 1992The FlexiGard 330 intrauterine copper contraceptive (ICC) was studied by ultrasound in 405 patients immediately following insertion and at each follow-up visit, for up to 5 years. The present study confirms the validity of the anchoring concept for the suspension of bioactive substances in the uterine cavity. The major conclusion from the study is that

330 Surgery of lung metastases
European Journal of Cancer, 1995Background A retrospective analysis was performed of the results of surgical excision of lung metastases in children to identify prognostic factors. Methods From 1970 to 1992 139 thoracotomies were performed in 91 patients aged between 1 and 19 years with metastases of osteogenic sarcoma (40), nephroblastoma (24), Ewing sarcoma (12) and various ...

The Interstellar Reddening and Metallicity of NGC 330
Symposium - International Astronomical Union, 1991A reddening of E(B-V) = 0.12 ± 0.02 has been determined for NGC 330 in the Small Magellanic Cloud (SMC) from spectrophotometry of B stars in the cluster. This high reddening helps explain many of the anomalous low metallicity estimates for the cluster. Preliminary analysis of Coudé spectra of K giants in the cluster indicates a high value of 3.5 to 4.5
