In order to investigate the effect of micronutrients foliar application on seed yield and essential oil of black cumin, a field experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications at the farmlocated in Naqadeh city, West Azerbaijan province, Iran, during 2015-2016 growing season. Treatments were separate application of Nano-Iron, Nano-Zinc and Nano-...
Black hole formation is an inevitable consequence of relativistic core collapse following the gravothermal catastrophe in self-interacting dark matter (SIDM) halos. Very massive SIDM halos form supermassive black holes (SMBHs) > or about 10(6)M(middle dot in circle) directly. Smaller halos believed to form by redshift z = 5 produce seed black holes of (10(2)-10(3))M(middle dot in circle) which ...
black seed is one of important ancient medicinal plants with various properties in traditional medicine. in order to evaluate microelements (fe and zn) effects on seed yield and yield components of black seed in salinity stress, a complete block design with three replications was conducted in esfahan agricultural and natural resources center during 2013-2014. three water salinity treatments wer...
in order to study different arrangements and weed controls effects on mung bean (vigna radiate l. wilczek) – black cumin (nigella sativa l.) intercropping an experiment was conducted at the research station of faculty of agriculture, ferdowsi university of mashhad, iran, during growing season 2005 – 2006. sixteen treatments comprising combinations of eight sowing patterns [a1: sole black cumin,...

Effect of weed competition periods on weeds and yield of black seed was studied through field experiments conducted at Agronomic Research Area, University of Agriculture, Faisalabad during winter 2006-07 and 2007-08. Weeds were allowed to compete with the crop for 40, 50, 60, 70, 80 days after sowing and throughout the growth season along with a weed free treatment. The data on weed density and...
An investigation was initiated to examine the effects of carbon soot collected from exhaust tube of 15 years old petrol and diesel operated vehicles on gram seed germination and biochemical changes of seedling. In view of the widespread cultivation of gram seed in India and long-term impact of black carbon is the warming of the atmosphere as per the recommendation of IPCC (2007). Black soot wer...
in order to study the effects of intercropping on yield of black cumin in intercropping with chickpea and bean, an experiment was conducted in a complete randomized block design with four replications. crops were planted as pure stands and intercrops in three arrangements: a) alternating rows of a field crop and a medicinal plant, b) two rows of field crops and one row of medicinal plant, c) al...
The properties of the first generation of black-hole seeds trace and distinguish different models of formation of cosmic structures in the high-redshift universe. The observational challenge lies in identifying black holes in the mass range ∼ 100 − 1000M⊙ at redshift z ∼ 10. Here we show that future groundbased laser interferometers could observe gravitational waves produced by the coalescence ...
We present a new model for the formation of black holes in cosmological simulations, motivated by the first star formation. Black holes form from high density peaks of primordial gas, and grow via both gas accretion and mergers. Massive black holes heat the surrounding material, suppressing star formation at the centres of galaxies, and driving galactic winds. We perform an investigation into t...
