Influence of carrier diffusion on the response of a resonant-cavity enhanced detector
(IEEE Journal of Quantum Electronics, 2002)
We have investigated the effects of carrier diffusion on the impulse response of a resonant-cavity enhanced photodetector using our analytic expression for a short-circuit current. Our theoretical results indicate that ...
A new type of slow-wave PBG microstrip structures
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2002)
Mass transfer in vertical two-phase flow of liquid coarse particles / Prenos materije u vertikalnom dvofaznom toku tečnost-krupne čestice
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije, Beograd, 2002)
Wall-to bed mass transfer in single-phase and vertical two phase flow of inert spherical particles 1.20, 1.94 and 2.98mm in diameter in a 25.4mm I.D. tube was studied. Mass transfer coefficients were determined by following ...
Reflection and structural characteristics of semi-bright and mirror bright nickel coatings / Refleksione i strukturne karakteristike polusjajnih i ogledalski sjajnih prevlaka nikla
(Serbian Chemical Society, 2002)
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening addition agent are examined. It is shown ...
Interaction of different third intracellular loop fragments of human dopamine d2l receptor with a-subunit of gi1 protein - prospective therapeutic application / Interakcija različitih fragmenata treće citoplazmatične petlje dopaminskog d2l receptora čoveka sa a-podjedinicom gi1 proteina - moguća terapeutska primena
(Jugoslovenska medicinska biohemija, 2002)
In order to find the essential structural motif of the D2L dopamine receptor necessary for the interaction with a-subunit of Gi1 protein, four fragments of the third cytoplasmic loop (CPL3) of this receptor were cloned, ...
Partial hydrogenation of edible oils: Synthesis and verification of the nickel catalyst / Parcijalno hidrogenovanje jestivih ulja - sinteza i verifikacija katalizatora na bazi nikla
(Association of Chemical Engineers of Serbia, 2002)
Developed in the late 1800s as a butter substitute, margarine is made with vegetable oils. Margarine was created by a scientist from Provence (France) Hippolyte Mege-Mouries, in response to an offer by the Emperor Louis ...
Hydride reduction of B-norcholestane 5α,6α-epoxide / Hidridna redukcija B-norholestan 5α,6α-epoksida
(Serbian Chemical Society, 2002)
B-Norcholestane epoxide 2 is reduced with lithium aluminium hydride to give either the 3β,6α-diol 3 or the corresponding 3β,5α-diol 4, depending on the quality of the reducing reagent employed. Aplausible mechanistic ...
Leucine aminopeptidase from Streptomyces hygroscopicus is controlled by a low molecular weight inhibitor
(Society of Fermentation and Bioengineering, 2002)
In culture filtrate of Streptomyces hygroscopicus a producer of polyketide antibiotics, a leucine aminopeptidase and its autogenous inhibitor were detected. The leucine aminopeptidase was purified 4573-fold with yield of ...
