Hyperfine structure of neutral vanadium lines and livels

We have recorded hollow-cathode spectra of neutral vanadium by Fourier transform spectroscopy in the near infrared - visible region (9000-17 000 cm-1). 36 transitions showing hyperfine structure have been analyzed, allowing us to deduce magnetic dipole constants for 27 levels belonging to the 3d44p and 3d34s4p configurations. For 22 of these levels no data were previously available

SPATIODATA, une approche alternative pour la gestion des données spatialisées relatives aux bâtiments

peer reviewedThere are an increasing number of mobile applications supporting specific activities related to the indoor building environment. SpatioData is a research project aiming at the development of a collaborative platform for the effective sharing of building-related data and supporting a wide range of different activities. After presenting the initial requirements of the system, this paper provides a review of the standards for the building modeling and the commercial solutions currently available. Then, it describes the SpatioData building model, as well as the general system architecture.SpatioDat

Neurophysins as markers of vasopressin and oxytocin release. A study in carcinoma of the lung.

Vasopressin-neurophysin (hNpI), oxytocin-neurophysin (hNpII) and blood osmolality were assayed before any treatment in basal conditions in 35 patients suffering from lung carcinoma (20 oat cell, 6 undifferentiated and 9 well-differentiated epidermoid cell carcinomas). Plasma vasopressin (antidiuretic hormone, ADH) was also assayed in 7 of the 20 patients suffering from oat cell carcinoma. We found a close correlation (r = 0.98) between plasma ADH and hNpI levels in the 7 patients. Further, hNpI was elevated in 13 out of the 20 oat cell carcinoma patients and in none of the epidermoid-cell carcinoma group; however, searching for an abnormality of ADH secretion as reflected by a detectable plasma hNpI level together with subnormal plasma osmolality revealed 2 additional positive results in the oat cell carcinoma group, and 2 out of the 6 in the undifferentiated-cell carcinoma group. hNpII was increased together with an increase in hNpI in 6 oat cell carcinoma patients; it was specifically increased without hNpI increment in 2 additional oat cell carcinoma patients and in 2 patients of the undifferentiated-cell carcinoma group (different from the 2 positive for the hNpI-osmolality ratio). hNpI and hNpII were normal in the majority of undifferentiated and all of the differentiated epidermoid-cell carcinoma group. Hence, our results show that simultaneous measurements of hNpI, hNpII, and blood osmolality could detect abnormalities in 17 out of 20 oat cell carcinoma patients, in 4 of the 9 undifferentiated-cell carcinoma patients, but in none of the differentiated epidermoid-cell carcinoma patients, suggesting that the neurophysin assay can be used for the early detection of oat cell- and possibly other neuroendocrine-derived carcinomas
