Characterization of Trypsin-Like Enzymes from the Midgut of Morimus Funereus (Coleoptera: Cerambycidae) Larvae / Karakterizacija tripsinima-sličnih enzima srednjeg creva larvi Morimus funereus (Coleoptera: Cerambycidae)
(Inst Bioloska Istrazivanja Sinisa Stankovic, Beograd, 2009)
The pH along the midgut of M. funereus larvae had different values, being acidic in the anterior section and basic in the middle and posterior sections. Elastase- and chymotrypsin-like activities were highest in the middle, ...
Acid-base equilibria of the Zn(II) and Fe(III) complexes with condensation products of 2-acetylpyridine and the dihydrazide of oxalic and malonic acid / Kiselinsko-bazne ravnoteže kompleksa Fe(III) i Zn(II) sa kondenzacionim derivatima 2-acetilpiridina i hidrazida oksalne, odnosno malonske kiseline

Nano-technologies from the aspect of human environment and safety and health at work
(Association of Metallurgical Engineers of Serbia AMES, 2009)
In the last couple of years the term ″nano-technology″ is very often used to
describe process technologies and analytical techniques used during synthesis of
materials in ultra fine range of magnitude of the millionth ...
Use of the sulfide minerals pyrite and chalcopyrite as electrochemical sensors in non-aqueous solutions. The potentiometric titration of weak acids in alcohols
(Versita, Warsaw 41, 2009)
Natural monocrystalline pyrite and chalcopyrite were examined as new indicator electrodes for the potentiometric titration of weak acids in tert-butanol and iso-propanol. The electrodes investigated demonstrated a linear ...
