The effects of magnetic treatments on germination and the initial growth stages of triticale seeds have been studied. Germination and growth tests were carried out under laboratory conditions by exposing triticale seeds to 125 mT for different times (1, 10 and 20 min, 1 and 24 hour). The rate of germination was assessed by determining the mean germination time (MGT) and time required to germina...

Let V be any set of n points in k-dimensional Euclidean space. A subgraph of the complete Euclidean graph is a t-spanner if for any ~ and ~ in V, the length of the shortest path from u to v in the spanner is at most t times d(~, ~). We show that for any 5 > 1, there exists a polynomial-time constructihle tspanner (where ~ is a constant that depends only on 5 and k) with the following properties...

Fluidic oscillators have proven their capabilities and advantages in terms of the generation oscillating jets without moving parts for many years, mainly experimental studies. In this paper, design, development, integration fluidic atomizers into liquid-fuel system dual-fuel low NOX Advanced Can Combustion (ACC) MAN Gas Turbines (MGT) are presented. The two-stage comprises a pressure-swirl nozz...

Description: Support to smallholder irrigation agriculture by virtue of establishing smalland medium-scale irrigation perimeters along the Eastern and South-Eastern slopes of Mt Kenya. In the first two phases (phase III ongoing, phase IV under preparation) approx. 2,700 smallholder farmers benefited from the establishment of 1,785 hectares of newly irrigated land (6 perimeters with altogether 4...

soil and water salinity in arid and semi-arid regions, is one of the most important stresses, can severely limit crop production. black cumin (nigella sativa l.) is annual important herbal plant in rununculaceae family that sense to salinity. this study was conducted to evaluate the effects of the priming on seed germination of black cumin under saline stress. the experiment was carried out as ...

The rapidly advancing field of the nuclear spectroscopy into a large extend owes its success to the progress in the development of gamma-ray detectors. A new generation of germanium spectrometers employing principles of gamma-ray tracking like AGATA [1], GRETA [2] and DESPEC [3] are expected to make a significant improvement in the efficiency and the Peak/Total ratio over the presently existing...

Pistacia vera L. is a decidious tree. To investigate the influence of soaking seeds in polyamines (PAs) spermine (Spm), spermidine (Spd) and putrescine (Put) on seed germination and enhancing lateral root development of ‘Ghazvini’ pistachio seedling rootstock, the experiment were carried out in petri dishes and plastic bags. Seeds were soaked in PAs( Spd, Spm, and Put) at three concentrations( ...

<p>Turbin gas merupakan salah satu penggerak mula siklus terbuka dengan bahan bakar berupa minyak bumi, alam ataupun campuran antara bumi dan gas. Dalam perkembangannya turbin dapat dibuat dalam skala mikro membalik prinsip <em>turbocharger</em> menjadi mikro. Penelitian ini meliputi pengujian atau <em>micro turbine</em> (<em>MGT</em>)<em> </em...

In this paper, we consider a viscoelastic plate equation of Moore-Gibson-Thompson with heat conduction Cattaneo type. We investigate the system in bounded and unbounded domains, seeking exponential stability domains polynomial decay rates for Cauchy problem. It turns out that our is exponentially stable domain, while has regularity loss Our results are proved sub-critical case $ K>0.
