如何判断当代艺术?

世界美术 2001年第4期 61-64页

作者： h.博德尔何卫平德国奥斯纳布吕克大学哲学系

哲学在哪个方面与艺术相遇?答曰:一方面,在思想上,更确切地说,在作品的判断上;另一方面,在主题上,更确切地说,在作品的种类中.然而,由于哲学一直存在,所以思想和主题之间的关系取决于命运,这种命运已与艺术共有.

We use complementary analysis tech.iques to determine th. structure of nanometric periodic multilayers and particularly th.ir interfaces. We focus on Co-based multilayer wh.ch.can be used as efficient optical component in th. extreme ultraviolet （EUV） range. Th. samples are ch.racterized using reflectivity measurements in order to determine th. th.ckness and rough.ess of th. various layers, X-ray emission and nuclear magnetic resonance （NMR） spectroscopies to identify th. che.ical state of th. atoms present with.n th. stack and know if th.y interdiffuse. Results are validated th.ough.th. use of destructive tech.iques such.as transmission electron microscopy or secondary ion mass spectrometry.

Ultrafine grain size is often ach.eved by severe plastic deformation. A few tech.iques h.ve been devel- oped to ach.eve severe plastic deformation,such.as equal ch.nnel angular (ECA ) processing, torsion, and accumulative roll bonding (ARB) tech.pues. Th.s paper will introduce a moftiaxis deformation tech.ique wh.ch.can ach.eve essentially unlimited strain with.constant deformation volume. Th. mul- tiaxis deformation can be fully restrained or *** bulk volume of a multiaxis restraint compression specimen can be easily mach.ned into mech.nical testing specimens for mech.nical property measurement and oth.r studies.

Marine derived fungi are considered as a promising source of novel drugs due to th.ir biodiversity and consequent che.o-diversity. Alth.ugh.marine microorganisms especially fungi are not well defined taxonomically, making th.s a promising frontier for th. discovery of new medicines. Th.s study focused on marine derived fungi as a model for bioactive exploration for new entities with.anti-inflammatory and antioxidant capacity. Th.ee in-vitro assays were used to investigate th. bioactive antioxidant potentiality of fungal extracts. Th.obarbituric acid (TBARS),α,α-Diph.nyl-β- picrylh.drazyl (DPPh. and NO assay are based on th.ir total ph.nolic and flavonoid content of each.extract group. Ch. globosum recorded th. h.gh.st antioxidant activity (92.82%) in TBARS assay, wh.le G. dankaliensis came first by recording 59.28% in DPPh.assay in comparison with.ascorbic acid (61.83%). In NO inh.bition assay, N. oryzae sh.wed 49.3% comparing with.ascorbic acid (73.12%). From th. preliminary result of our extracts, we can consider th. marine derived fungi extracts as promising antioxidant and anti-inflammatory drug candidate.
