Analysis of more than 20 projects for clustering small and medium enterprises and supporting organizations in different Latin American countries has uncovered a number of barriers, activities, structures, strategies, policies and procedures that impact competitiveness. These factors mean that there are different appropriate industrial cluster and industrial business models appropriate for the s...

The majority of skill-upgrading in the United States in the 1980s and early 1990s was due to within industry shifts in skill-intensity. Traditional trade theory, represented by the HeckscherOhlin model, predicts that trade affects relative employment primarily by shifting resources across industries. For this reason, many economists have concluded that international trade has played a minor rol...

After explaining the basic operation of a SiC JFET plus silicon MOSFET cascode circuit, the dynamics of cascode switching will be discussed and the use of a QRR tester to evaluate the reverse-recovery characteristics of a cascode circuit will be explained. A comparison of the cascode’s reverse recovery with that of a SiC MOSFET reveals that the JFET cascode actually performs better than the SiC...

One of the most important items of modern agriculture is the reduction of environmental impact thanks to the integration of new cultivation and protection techniques. Therefore it is important to optimise the use of chemicals and pesticides. We found that some coadjutants applied in tank mix with fungicides on sugar beet protection improve the effectiveness of active principles in cercospora le...
