Sesquiterpene lactone from Achillea crithmifolia
(Elsevier, 1993)
Achillea crithmifolia Waldst. et Kit. (Asteraceae) is used in folk medicine against the same disorders as the well known Achillea millefolium L. (Asteraceae). Hitherto, four guaianolides (rupicolin-A and -B and their ...
Dependance of avalanche photodiode characteristics on active area geometry
(Institute of Electrical and Electronics Engineers (IEEE), 1995)
The work presents an analysis of avalanche photodiode (APD) with spherical p-n junction. The calculation results are given for the dependence of the avalanche multiplication and noise parameters on geometry and on the ...
The Influence of Sintering Conditions on the Microstructure and Magnetic Properties of Sintered SmCo5 Magnets
(Springer Science and Business Media LLC, 1999)
Since the magnetic features of the magnet of Sm-Co type are in direct connection with microstructure, it is indispensable to achieve, in the procedure of synthesis of these materials, the microstructure which ensures the ...
Investigation of the Microstructure and Distribution of Solute During Solidification of Al-Cu Alloy
(Springer Science and Business Media LLC, 1999)
Phenomenon of solidification process plays an important role in various areas like: crystal growth, casting processes, liquid phase sintering etc. Results presented in this paper contribute to investigation of the influence ...
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 ...
Integrated multicolor detector utilizing 1-D photonic bandgap filter with wedge-shaped defect
(Society of Photo-Optical Instrumentation Engineers (SPIE), 1999)
Abstract
We propose a single-chip multicolor photodetector for (3-5) μm range based on a linear IR semiconductor detector array with an integrated 1-D photonic bandgap (PBG) filter. A wedge-shaped defect slab (corresponding ...
Numerical calculation of photodetector response time using Ramo's theorem
(Institute of Electrical and Electronics Engineers (IEEE), 1995)
The work presents a methodology for numerical calculation of response time of p-i-n photodiodes using the corpuscular approach, i.e. the Ramo's theorem. The calculations were performed for the Si p-i-n photodiode homostructure ...
Ceruloplasmin, copper and zinc in pulmonary emphysemia
(Bulgaria : Balkan Federation of Clinical Laboratory, 1996)
We analyzed the blood samples from 20 patients with global respiratory failure (10 males, mean age 56±7 yrs. and 10 females, mean age 60±5 yrs.). All patients were heavy cigarette smokers, in average 33±8 pack-years.

Dismutacija azot oksida (NO) kompleksima gvožđa i aminokiselina
(Belgrade : Serbian Chemical Society, 1999)
Reakcije NO sa prelaznim metalima čine osnovu za dejsvo NO u biološkim sistemima.
Reakcije NO sa proteinima koji sadrže hem intenzivno su izučavane. Medjutim, reakcije NO sa drugim metalnim centrima koji se nalaze u ...
Spektrofotometrijsko određivanje acetaldehida u biološkom materijalu
(Belgrade : Serbian Chemical Society, 1994)
Za analizu korišćeni su uzorci venske krvi pripremljenih sa dodatkom ACĐ rastvora i hloralhidrata i do upotrebe čuvani na <4°C. Standardni rastvori acetaldehida su pripremljeni razblaživanjem standardnog rastvora acetaldehida ...
