The aim of this study was to verify the viability of lignocellulosic substrates to obtain renewable energy source, through characterization of the cellulolytic complex, which was obtained by solid state fermentation using Trichoderma viride. Enzymatic activity of the cellulosic complex was measured during saccharification of substrates filter paper, eucalyptus sawdust, and corncob, and compared...

During the past two decades, the involvement of non-academic sponsors of biomedical research, particularly clinical trial research, has increased exponentially. It is estimated that between 1980 and 2003 the overall research and development expenditure by US pharmaceutical companies increased from $2 billion to $33 billion [1]. The sources of funding for biomedical research have also shifted si...

The coordination compounds of Fe (II) and Fe(III) with phthalic acid were synthesized. The compounds were studied by X-Ray Diffraction (XRD), Differential Thermal Analysis (DTA), and IR spectroscopy. It has been established that, regardless of the oxidative number of iron, the synthesis products have the same chemical composition and chemical formula - [Fe2(o-C6H4...

Comparing spoken dialogue systems in commercial and research background reveals a great discrepancy in state-of-the-art systems. Whereas research systems tend to be very complex, allowing free and exible dialogues using unrestricted speech, commercial systems are restricted to far less complex solutions such as menu-driven systems based on simple keyword-spotting, mostly doing completely withou...

Background and Aims: Infectious bronchitis virus (IBV) causes an acute, highly contagious respiratory and kidney disease of chickens which results in significant economic losses in commercial broilers, layers and breeders. Rapid identification of IBV serotypes involved in respiratory complex is a problem in the differential diagnosis. Materials and Methods: In this study, a single and mul...

A multiplex PCR designed to differentiate Mycobacterium tuberculosis complex organisms from M. avium and M. intracellulare was used to test 105 isolates identified by DNA probe methods as M. avium, M. intracellulare, or M. avium complex type X. The multiple PCR correctly identified 33 of 34 isolates identified by commercial probe methods as M. avium and all 51 isolates identified as M. intracel...

This article provides an updated overview of the plethora of complex I inhibitors. The inhibitors are presented within the broad categories of natural and commercial compounds and their potency is related to that of rotenone, the classical inhibitor of complex I. Among commercial products, particular attention is dedicated to inhibitors of pharmacological or toxicological relevance. The compoun...

Purpose: Commercial aviation is feasible thanks to the complex socio-technical air transportation system, which involves interactions between human operators, technical systems, and procedures. In view of the expected growth in commercial aviation, significant changes in this socio-technical system are in development both in the USA and Europe. Such a complex socio-technical system may generate...

This paper reports on methods for the analysis of electrical machines by combined electromagnetic and thermal models using commercial software which can be an aid to the design of these machines. Examples using a brushless permanent-magnet motor and an induction motor illustrate the tools available and techniques possible.
