for continues production if field crops in arid and semi arid regions of the world, such as iran, beside of using of drought resistant varieties, water management must also be considered. in this context, the use of tape drip irrigation system could reduce the amount of irrigation water consumption. this study, was conducted to determine the best sowing pattern of sugar beet under type drip irr...

The aim of this study was to evaluate the potential of microemulsions as a drug vehicle for transdermal delivery of citalopram. A computerized statistical technique of response surface methodology with mixture design was used to investigate and optimize the influence of the formulation compositions including a mixture of Brij 30/Brij 35 surfactants (at a ratio of 4:1, 20%-30%), isopropyl alcoho...

A moving-slab-geometry Nd:glass laser has been designed and demonstrated. An average power output of 43.8 W has been achieved at 2.76-kW input power and at 2.06% slope efficiency. The moving-slab laser has the potential for scaling to kilowatt average power levels.

This study explored the influence of moringa (Moringa oleifera; MO) foliage supplementation on in vitro ruminalgas production kinetics and substrate degradation cattle. In fermentation was carried out with twotypes substrates, viz. wheat straw (WS) WS plus concentrate mixture (CM; 60:40) cattle rumen inoculum.The MO incorporated to both substrates at 0, 5, 10, 20, 30, 40 50% levels total dry ma...

Accurate measurement of the softest sound levels of phonation presents technical and methodological challenges. This study aimed at (1) reliably obtaining normative data on sustained softest sound levels for the vowel [a:] at comfortable pitch; (2) comparing the results for different frequency and time weighting methods; and (3) refining the Union of European Phoniatricians' recommendation on a...

Upper airway pressure was measured during maximal exercise in 10 Thoroughbred racehorses with naturally occurring upper airway obstruction. Left laryngeal hemiplegia and arytenoid chondropathy resulted in substantial increases (30-40 cm H2O) in inspiratory upper airway pressure (Pl), whereas complicated aryepiglottic entrapment and subepiglottic cysts produced only modest increases (15 cm H2O) ...

Abstract We measured the parameter reproducibility and radial electron density profile of capillary discharge waveguides with diameters 650 $\mathrm{\mu} \mathrm{m}$ to 2 mm lengths 9 40 cm. To best authors’ knowledge, cm is longest plasma waveguide date. This length important for $\ge$ 10 GeV energy gain in a single laser-driven wakefield acceleration stage. Evaluation variations showed that t...

PURPOSE To create an accurate 6 MV Monte Carlo simulation phase space for the Varian TrueBeam treatment head geometry imported from CAD (computer aided design) without adjusting the input electron phase space parameters. METHODS GEANT4 v4.9.2.p01 was employed to simulate the 6 MV beam treatment head geometry of the Varian TrueBeam linac. The electron tracks in the linear accelerator were simu...
