Abstract Background Low temperature severely depresses the uptake, translocation from root to shoot, and metabolism of nitrate ammonium in thermophilic plants such as cucumber ( Cucumis sativus ). Plant growth is inhibited accordingly. However, availability information on effects low nitrogen transport remains limited. Results Using non-invasive micro-test technology, net (NO 3 ? ) (NH 4 + flux...

The article presents the results of long-term studies physiological processes and oxidative stress occurring in wheat plants under influence phytopathogens, mineral fertilizers fungicides. criteria for damaging effect are activity enzyme nitrate reductase concentration TBK-active products. Normally, a mobile balance is maintained between lipid peroxidation antioxidant system cell protection. Ho...

We propose to use a mask with a nonredundant array (NRA) of multiple apertures to measure spatial coherence in two dimensions. The spatial distribution of the apertures in the mask is made in such a way that we obtain a quasi-uniform sampling in the coherence domain. The spatial coherence is obtained by Fourier transform of the interferogram generated by the mask when it is illuminated by the l...

The 2nd International Workshop on News Recommendation and Analytics (NRA) brings together researchers on news analytics and stakeholders from the media industry. A particular focus is on news recommender systems, that tailor content from media houses and social sites to the preferences and context of individual readers. The workshop includes one invited speaker from the media industry and five ...

in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...

Depth resolution and probing depth for Li in lithium thin film batteries achievable using different ion beam analytical techniques were investigated. Experiments protons nuclear reaction analysis, He ions time-of-flight (TOF) energy elastic recoil detection analysis (ERDA) transmission geometry, as well coincidence ERDA geometry are performed. Experimental results compared terms of the obtained...

The aim of the present project is to investigate the effect of salinity on growth, biochemical parameters and fatty acid composition in six varieties of safflower as well as identification of stress tolerant variety under saline (8 d Sm) condition. It was observed that salinity significantly decreased the dry weight and fresh weight of safflower varieties. Nitrate reductase (NRA) and nitrite re...

Thermostable lipase from Geobacillus thermodenitrificans IBRL-nra was purified and characterized. The production of thermostable lipase from Geobacillus thermodenitrificans IBRL-nra was carried out in a shake-flask system at 65°C in cultivation medium containing; glucose 1.0% (w/v); yeast extract 1.25% (w/v); NaCl 0.45% (w/v) olive oil 0.1% (v/v) with agitation of 200 rpm for 24 hours. The extr...

We present measured scattering matrices as functions of the scattering angle in the range 5ø-173 ø and at wavelengths of 441.6 nra and 632.8 nra for seven distinct irregularly shaped mineral aerosol samples with properties representative of mineral aerosols present in the Earth's atmosphere. The aerosol samples, i.e., feldspar, red clay, quartz, loess, Pinatubo and Lokon volcanic ash, and Sahar...
