We can find many different types of commercial regulators in the market, these devices basically can be divided into two categories according to their operation mode: The first ones modulate the input voltage with PWM (pulse width modulation) to hold the constant voltage in the output necessary to charge the battery. The other ones operate in the MPP(More)
We assessed the structure and latitudinal selection that might result in sensitivities to critical day-lengths that trigger diapause between Culex pipiens populations distributed along North-South and East-West axes in eastern North America. Strong population structure between Cx. p. pipiens and Cx. p. quinquefasciatus existed. Among Cx. p. pipiens, a(More)
OBJECTIVE To report the results from participating laboratories for four external quality control proficiency tests of dengue serological diagnosis that were carried out in the Region of the Americas in the period of 1996-2001. METHODS External quality control proficiency tests of dengue serological diagnosis were carried out in 1996-1997, 1998-1999,(More)
A recently discovered technology facilitates the chemical breakdown of water into its elemental components, hydrogen and oxygen, by using a manganese-containing compound. The compound, chemical formula: [H2O(terpy)Mn(O)2Mn(terpy)OH2](NO3)3 acts as a catalyst in a chemical reaction that produces hydrogen and oxygen gas from liquid water. The task assigned to(More)
DC microgrids are becoming an economical alternative for local power generation. The mix of different renewable energies makes it necessary to use electronic systems compatible between them to supply common loads. This paper presents a photovoltaic regulator that can operate in the MPP of PV arrays regardless of the input PV array configuration or the(More)
Psychopathy is the result of a complex interaction between biological and environmental factors; both participate in the final expression of the phenotype and can modulate the variation regarding beginning, deterioration, and severity. Nevertheless, up to now it has not been possible to determine the circumscribed molecular track and its interaction with(More)
