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 ...

Contact allergy in 330 dermatological patients
Contact Dermatitis, 1978A total of 330 patients with eczematous lesions were tested with 27 topical substances. Among the 88 patients with leg ulcers, 85 (2 %) were allergic to one or more substances present in one out of two cases of allergy to wool alcohol. Among the 242 patients suffering from eczematous dermatitis, ihe percentage of allergic reactions reached 54.6 %.

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
