Lorentzian circle as a Lie group and a C ∞ action on Lorentz spaces of two dimension
(1999)
We define a product on Lorentz circle that is similar to Lorentzian inner product. This product is expanded to Lorents space of two dimension. So we have an C{\infty} action of Lorentz circle on Lorents space of two ...
Data extraction from CAD model for rotational parts to be machined at turning centres
(Scientific and Technical Research Council of Turkey, Ankara, Turkey, 1999)
Among the most important data produced and stored is product data. CAD data forms one of many contributors to product data. Although in most circumstances CAD data can be processed within the CIM environment by integrated ...

Tautomeric properties, conformations and structure of N-(2-hydroxy-5-chlorophenyl) salicylaldimine
(Elsevier Science Bv, 1999)
The crystal structure of N-(2-hydroxy-5-chlorophenyl) salicylaldimine (C13H10NO2Cl) was determined by X-ray analysis. It crystallizes orthorhombic space group P2(1)2(1)2(1) with a = 12.967(2) Angstrom, b = 14.438(3) Angstrom, ...
Functionalization of low molecular weight atactic polypropylene - Part I. Spectroscopic studies
(Springer Verlag, 1999)
Low molecular weight atactic polypropylene (APP) was functionalized with 4-allyl-2-methoxyphenol (eugenol), 4-allyl-1,2-dimethoxybenzene (DMAB), 4-propenylanisole(trans-anethole), cis-2,4,5-trimethoxypropenylbenzene ...
3,3-dichloro-1,4-diphenylazetidin-2-one
(Munksgaard Int Publ Ltd, 1999)
In the crystal structure of the title compound, C15H11C12NO, the Cl-C-Cl plane is nearly perpendicular to the four-membered beta-lactam ring [89.0 (2)degrees] and the C-C bond distances in this group are 1.571 (6) and 1.543 ...
Determination of trace metals in geological samples by atomic absorption spectrophotometry after preconcentration by Aspergillus niger immobilized on sepiolite
(Japan Soc Analytical Chem, 1999)
A method for the determination of Cu, Zn, Fe, Ni and Cd in geological samples by flame atomic absorption spectrophotometry (FAAS) after preconcentrating by Aspergillus niger immobilized on sepiolite has been developed. The ...
3,3-Dichloro-1-(p-chlorophenyl)4-(p-methoxyphenyl)-2-azetidinone
(Wiley-Blackwell, 1999)
The crystal structure of the title compound, C16H12Cl3NO2, has a nearly planar beta-lactam ring with the N atom out of the best plane by 0.032(2) Angstrom. The C-C bond distances in the beta-lactam ring are 1.544(4) and ...
