Recently there has been another round of controversial news regarding genetically modified organisms (GMO). Perhaps the best known debate on these centers on corn. A recent French study showed severe kidney and liver abnormalities in rats that were fed this corn for up to 2 years. Immediately afterward, Russia banned the use of this seed and the corn it produces. Because other studies have not ...

This paper presents a study and design methodology for enhancing the efficiency of the SLED II rf pulse-compression system [1]. This system employs resonant delay lines as a means of storing rf energy. By making the external quality factor of these lines vary as a function of time, the intrinsic efficiency of the system can reach 100%. However, we demonstrate a considerable increase in efficien...

Purpose: The aim of this research is developing a moral model for Safe and   violence free family for based on Naraqi’s ideas in the book "Jameo' Alsa'adat" (1388). Methods: This qualitative study was conducted using themes analysis and synthesis. For intellectual foundations of the therapy, Naraghi's ideas were used. Themes of moral treatment were extracted from books about morality, especiall...

in this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (lims). dynamical equations of lim have been considered accurate. in other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. then equations of the reference model and adaptive mode...

In this Paper, complete models of three and six phase self commutated synchronous machine drives are presented, considering the effects of both time and space harmonics. First, the equations for calculation of machine inductances are developed. Next, "thyristor-inverter-electric machine" set is modeled in order to derive all the equations for conduction and commutation states. Finally, the resu...

A high-power low-loss mode transducer design has been proposed to adapt the output of the X-Band klystron, WR.90 rectangular waveguide, to the input of the pulse compression system, SLED II, which utilizes overmoded circular waveguides operating in the low-loss TEol mode. This device is much more compact than the conventional Marie’ type mode converters. The device splits the incoming klystron ...

Despite of the fact that large line segment datasets are becoming more and more popular, most of the analysis for estimating the selectivity of window queries posed on spatial data {the most important parameter for query optimization{ has focused on point or region data only. In this paper we move one signiicant step forward in line segment datasets theoretical analysis. We discovered that real...
