Model of Drawing Thin Glass Sheet From A Rectangular Preform and Its Applications
(Springer Science and Business Media LLC, 1999)
Glass sheets of uniform thickness, thinner than lmm, are commonly used, for example, in microelectronics, as small parts of electronic devices, and components in light microscopes, etc. Drawing glass from rectangular ...
Guaianolides from Centaurea nicolai: Antifungal activity
(Elsevier, 1999)
A new guaianolide, 3-deacetyl-9-O-acetylsalograviolide A, along with four known closely related lactones, salograviolide A, 9-O- acetylsalograviolide A, kandavanolide and salograviolide B were detected in the aerial parts ...
Essential oil of anthemis montana
(Taylor & Francis, 1998)
The essential oil of Anthemis montana L. (Asteraceae) has been analyzed using GC and GC/MS. Forty-two components were identified. The major fractions belonged to α-thujone (46.9%), β-thujone (16.0%), and trans-chrysanthemyl ...
Crystal Structure and Solid State Conformation of 5‐Hydroxy‐8,9‐Dioxo‐8,9‐Seco‐α‐Cholestan‐3β‐yl Acetate
(Comltb van Beheer van het Bulletin V.Z.W., 1993)
The molecular structure of the title compound, which might be a possible intermediate in the synthesis of 5,10:8,9‐diseco‐steroids (=steroklastanes), was determined by X‐ray analysis. Hydrogen bonding between the 5α‐hydroxyl ...
Optical properties of guanidinium aluminium sulphate hexahydrate (GASH)
(IOP Publishing, 1993)
Far-infrared reflection spectra were determined, for the first time, for single crystals of guanidinium aluminium sulphate hexahydrate (GASH) and its solid solution for 5 mol.% chromium isomorph (GCSH). The infrared active ...
