متن کاملAm I Right or Am I Right?
Though the value of a right should be not lower than zero, negative voting premiums often appear in recent empirical evidence. The present paper highlights some possible measurement errors and contemporary proposes a new measure, the vote segment, which incorporates all dividend privileges. Results from Italian non-voting shares listed in the 1999-2008 period show that the more accurate measure...

The repellency and insecticidal efficacy of Nopikex®, a soap formulation containing 20% diethyl toluamide and 0.5% permethrin, was evaluated against a laboratory colony of phlebotomine sand flies (Lutzomya longipalpis). The repellency of Nopikex soap was also compared with that of a placebo soap against another species (Lu. Youngi) in a forest near Tulua, Valle del Cauca, Colombia. In laborator...
متن کاملWideband Power Amplifier Modeling Incorporating Carrier Frequency Dependent AM/AM and AM/PM Characteristics
In this article, we present a complex baseband model for a wideband power amplifier that incorporates carrier frequency dependent amplitude modulation (AM) and phase modulation (PM) (i.e., AM/AM and AM/PM) characteristics in the design process. The structure used to implement the amplifier model is a Wiener system which accounts for memory effects caused by the frequency selective nature of the...
متن کاملDesigning an Am-Be miniature neutron source
Background: Miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. The most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. In this research, we have surveyed and designed an Am-Be miniature neutron source fabrication. Materials and Methods: This investigation resulted in creation...
