introduction: the main objective of all organizations is to improve the efficiency and effectiveness of the personnel’s performance and this partly depends on effective management. managers are valuable assets and studying their behavior and personality dimensions may provide important guide for effectiveness and efficiency improvement. in this connection, the objective of this research is to d...

Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus limit learning about the profitability of alternative firm sizes. The model shows how lack of informatio...

Adaptive coded modulation (ACM) is a promising tool for bandwidth-efficient transmission in a fading environment. The main motivation behind employing ACM schemes is to improve the spectral efficiency of wireless communications. In this paper, we present a method This work was supported in part by the NTNU project IKT-webtek (http://www.ntnu.no/ satsingsomraader/ikt/focus1.htm), in part by the ...

Lycopene nanoemulsions were prepared to protect the antioxidant activity and improve the bioaccessibility of lycopene-enriched tomato extract (containing 6% of lycopene) by an emulsification-evaporation method. Lycopene nanoemulsions, with droplet sizes between 100 and 200 nm, exhibited higher anti-radical efficiency and antioxidant activity, than did those smaller than 100 nm. Strong protectab...

Manufacturing and Testing techniques were investigated for the development of efficient joining of composite tubes. The stepped lap joining arrangements were studied. Finite element models were developed using ANSYS finite element code for predicting the stress distribution of the joint under the applied loads. Tubes made of graphite/epoxy were considered. The tubes were tested under both tensi...
