H+-ATPase activity in leaves and roots of coconut palms growing in 'root wilt disease-prevalent areas' was compared with that of coconut palms growing in 'disease-free areas'. The activity was found to be significantly less in the leaves and roots of palms in the disease-prevalent zone as compared to that in disease-free zone. Histochemical examination of the leaves showed results that corrobor...

protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. in this work, the time-lapse electrical resistivity tomography (ert) surveys were conducted along 7 longitudinal lines in the downstream of the latian dam in jajrood (iran), in order to detect the contamination resulting fro...

Results of radar monitoring of the sea surface in the Russian sector of the Black Sea coastal zone are presented. The attention was focused on the detection of oil pollution as well as biogenic and anthropogenic surfactant films. The basic data were high resolution radar images obtained by synthetic aperture radars (SAR) on board Envisat and ERS-2 satellites of the European Space Agency. Spatia...

Air Traac Management (ATM) of the future allows for the possibility of free ight, in which aircraft choose their own optimal routes, altitudes, and velocities. The safe resolution of trajectory connicts between aircraft is necessary to the success of such a distributed control system. In this paper, we present a method to synthesize provably safe connict resolution maneuvers. The method models ...

This paper presents a new magnetophoretic position detection method for multiplexed immunoassay using colored microspheres for encoding of target analytes and superparamagnetic nanoparticles (SMNPs) for quantitative analysis. Under the magnetic field gradient, reacted microspheres are deflected as much as analytes and SMNPs are conjugated with them. The positions of colored microspheres were co...

Active management of distribution networks and different controllable resources will play a key role in future Smart Grids. This paper proposes that centralized active network management functionalities at MV level could also include an algorithm which in real time confirms reliable islanding detection with local measurements based passive method. The proposed algorithm continuously ensures tha...

We perform helioseismic holography to assess the noise in p-mode travel-time shifts which would form the basis of inferences of large-scale flows throughout the solar convection zone. We also derive the expected travel times from a parameterized return (equatorward) flow component of the meridional circulation at the base of the convection zone from forward models under the assumption of the ra...

In this paper, we propose two new vision-based methods for irzdooimobile robot navigation. One is a selflocalization algorithm using projective invariant and the other is a method for obstacle detection by simple image difference and relative positioning. Foia geometric model of corridor erzvironnaent, we use natural features formed by floor, walls, and door frames. Using the cross-ratios of th...
