A catadioptric vision system using diverse mirrors has been a popular means to get panoramic images(K.Nayar, 1997) which contains a full horizontal field of view (FOV). This wide view is ideal for three-dimensional vision tasks such as motion estimation, localization, obstacle detection and mobile robots navigation. Omnidirectional stereo is a suitable sensing method for such tasks because it c...

The effect of varying Nao and Nai on Ca efflux while maintaining the ratio Nao/Nai constant was explored in squid giant axons dialyzed with and without ATP. In the absence of ATP, the Ca efflux increased 3.4 +/- 0.2-fold when the Nao/Nai concentrations were reduced from 440/80 to 110/20 mM. In the presence of ATP a similar change did not have an appreciable effect. The inhibition of Ca efflux p...

Research into the development of new data-storage strategies is fueled by the continuing demand for ultrahigh information capacity, increased data density, smaller form factor, and faster readout rates. Conventional data-storage devices such as magnetic hard-disk drives, optical disks, and semiconductor memories all rely on storing information bit by bit on the surface of a recording medium. Ho...

The effect of four different levels of irrigation periods, including normal irrigation, irrigation after 100, 150, and 200mm evaporation, with three different bio-fertilizer including control, Mycorrhiza, and Rhizobium were investigated on morphological and yield traits of guar. The experiment was conduct in form of split-plot design with irrigation periods as main plots and bio-fertilizers as ...

Background: This study aims to investigate radiation beam geometry of Cyberknife beam and change in dosimetric characteristics of six megavoltage (6MV) flattening filter free (FFF) beam after passing through high density cadmium free compensator alloy.Material and Methods: In this experimental study, changes in FFF beam dosimetric characteristics after passing through compensator alloy wa...

It is well-established that micro-scale wind turbines require high blade solidity in order to overtake friction torque of all mechanical parts and starts operating. Therefore, multi-bladed rotors with a low design tip-speed ratio ? are advocated. However, no consensual admitted by the scientific community at Reynolds number because reliability airfoil data, used element momentum theory, questio...

Interactive effects of solar radiation and inorganic nitrogen phosphate on biofiltration capacity, biomass production, photosynthetic activity the accumulation bio-active compounds were studied in red alga Gracilaria cornea grown tanks with a seawater open-flow system during 35 days. Two light conditions utilized: outdoor (O), full natural radiation, indoor, inside greenhouse (G) where UV-B was...

Using a combination of small-angle X-ray scattering (SAXS) and fluorescence resonance energy transfer (FRET) measurements we have determined the role of the H3 and H4 histone tails, independently, in stabilizing the nucleosome DNA terminal ends from unwrapping from the nucleosome core. We have performed solution scattering experiments on recombinant wild-type, H3 and H4 tail-removed mutants and...

The purpose of this experiment was to examine the stress response of wild type Arabidopsis thaliana to treatment with different sodium chloride concentrations. Previous research has shown that sodium chloride induces a stress response from plants in both a physical sense and molecular sense. The hypothesis was that the plants would exhibit a number of different stress responses including shorte...
