Efficiency of comercial enzymatic preparations in grain hydrolyses for preparation of substrates for alcoholic fermentation
(European association for chemical and molecular sciences (EuCheMS), 2006)
In this study, we investigated the optimal composition of substrates and tested optimal enzyme concentration for most efficient substrate degradation.

A novel analytical model of a SiC MOSFET
(IEEE Computer Society, 2002)
This paper presents a novel analytical model for simulation of characteristics of a n-channel MOSFET based on silicon-carbide (SiC). Using known experimental results, a semiempirical relation for carrier mobility (/spl ...
Influence of adsorption-desorption process on resonant frequency and noise of micro-and nanocantilevers
(IEEE Computer Society, 2002)
Scientists in the field of NEMS today are focused on the problem of achieving the lowest detectable mass of the atomic force microscope and molecular microscope probes. This paper deals with this problem starting from the ...
Characterization of enzymatically synthesized diferulate
(New York Acad Sciences, New York, 2005)
Horseradish peroxidase was used to synthesize diferulates by a procedure in which ethyl ferulate was used as substrate. Four different forms were obtained, of which two dominant were the 5-5' and 8-5' diferulate. Fluorescence ...
1-D microstrip PBG filters without etching in the ground plane and with sinusoidal variation of the characteristic impedance
(IEEE Computer Society, 2001)
In this paper new types of (1-D) microstrip photonic band-gap (PBG) filters are presented. They have sinusoidal variation of the characteristic impedance in function of the length along the microstrip line. They are, also, ...
Composites based on nonwoven textile materials and alumosilicates / Kompoziti na bazi netkanih tekstilnih materijala i alumosilikata
(Savez inženjera i tehničara tekstilaca Srbije, Beograd, 2004)
The part of results obtained during the investigation of synthesis of composites based on nonwoven textile materials (NTM) and alumosilicates are presented. The newly obtained material is composite agro textile that can ...
Thermomechanical noise of nanooscillators with time-dependent mass
(Elsevier, 2007)
We consider the influence of adsorption-desorption (AD) kinetics on the response of micro/nanocantilever oscillators. We utilize the calculated response to analyze an oscillator with variable mass and determine the ...
A new class of electromagnetically coupled printed antenna arrays
(IEEE Computer Society, 2003)
A new class of electromagnetically coupled microwave printed antenna arrays using three coplanar strip-TCS (CPW with finite narrow ground strips) is reported. Two versions of this antenna array are introduced. (1) Antenna ...
A new type of slow-wave PBG microstrip ring resonator
(IEEE Computer Society, 2003)
A new type of microstrip ring resonator is introduced. In order to minimized dimensions the ring resonator is constructed like a PBG structure. The central frequency is 50% lower than in the conventional case. Additional ...
