Irrigated agriculture is facing a serious problem of water scarcity, which could be mitigated by optimizing the application regulated deficit irrigation (RDI) strategies. For this reason, aim our study was to determine thresholds based on direct status indicators apricot trees under RDI maximize productivity. Three treatments were tested: (i) Control (CTL), irrigated at 100% crop evapotranspira...

A simplified model for the prediction of carbon balance was developed to elucidate seasonal trend sink-source relationships in bearing and non-bearing pistachio (Pistacia vera L.) branches. Seasonal changes growth rate vegetative (leaf shoot) reproductive (infructescence) organs were monitored branches mature rainfed trees during entire growing season (April–September). Simulations from used ga...

this study was conducted under ahvaz, iran environmental condition during 2012 and 2013 growing seasons in order to investigate the influence of foliar application of potassium on some physiological and biochemical characteristics of three olive cultivars including ‘mission’, ‘koroneiki’ and ‘dezfuli’. potassium sulfate in different concentrations of 0, 1, and 2 g l-1 was sprayed twice on selec...

The highly diffuse nature of light propagation in biological tissue is a major challenge for obtaining high-fidelity fluorescence tomographic images. In this work we investigated the use of time-gated detection of early-arriving photons for reducing the effects of light scatter in mice relative to quasi-cw photons. When analyzing sinographic representations of the measured data, it was determin...

We present new near-infrared speckle interferometric observations of the young stellar object Elias 1. The emission is resolved into a narrow east-west elongated blue halo (FWHM about 0. ′′2x1. ′′0) and an unresolved core (FWHM < 0. ′′2). Previously, Kataza and Maihara (1991) had inferred an east-west elongated optically thin disk within which the NIR light is directly scattered. Adding new pie...

A prototype thermionic electron gun for a high-brightness X-ray generator has been developed. Its extraction voltage and design current are 60 kV and 100 mA (DC), respectively. The X-ray generator aims towards a maximum brilliance of 60 kW mm(-2). The beam sizes at the rotating anticathode must therefore be within 1.0 mm x 0.1 mm and a small beam emittance is required. The fabricated electron g...

A precise test of the theory of stellar evolution can be performed by measuring the difference in average energy between the neutrino line produced by Be electron capture in the solar interior and the corresponding neutrino line produced in a terrestrial laboratory. The high temperatures in the center of the sun broaden the line asymmetrically, FWHM = 1.6 keV, and cause an average energy shift ...

We designed, fabricated, and characterized a dielectric metamaterial lens created by varying the density of subwavelength low refractive index nanoholes in a high refractive index substrate, resulting in a locally variable effective refraction index. It is shown that a constructed graded index lens can overcome diffraction effects even when the aperture/wavelength (D/λ) ratio is smaller than 40...

A growing number of X-ray sources based on the free-electron laser (XFEL) principle are presently under construction or have recently started operation. The intense, ultrashort pulses of these sources will enable new insights in many different fields of science. A key problem is to provide x-ray optical elements capable of collecting the largest possible fraction of the radiation and to focus i...
