In order to get the information on the force-distance curve for the interaction between a dislocation and a solute atom, amplitude-dependent interna1 friction was measured at 1.7 30 K on Al-100 at ppm Zn and Al-50 at ppm Zn single crystals. The temperature dependence of applied strain under a constant decrement is the same for two concentrations with high accuracy. The data were analyzed by the...

Several explanations for the 200 to 280 ppm glacial/interglacial change in atmospheric CO 2 concentrations deal with variations in southern ocean phytoplankton productivity and the related use or nonuse of major plant nutrients. An hypothesis is presented herein in which arguments are made that new productivity in today's southern ocean (7.4 X 1013 g yr -1) is limited by iron deficiency, and he...

This study aimed at assessing the ability of sunflower to remediate zinc (Zn) impacted soils and partitioning factors Zn in soil-plants interactions. The research method used ex situ experiments using teddy bear seeds with 8 different treatments for each. began preparation sample soil media on garden soil, seeding seeds. was carried out six months starting August - December 2020, Helianthus ann...

The field experiment was carried out during Rabi season of 2021-22 at “Students’ Instructional Farm” Chandra Shekhar Azad University Agriculture and Technology, Kanpur. included two factors, viz. timely shown wheat varieties, V1-DBW-187, V2-K-1006, V3-K-607 in main-plot plant growth promoters (PGPs), G0- Control, G1- Nitrobenzene @ 3ml l-1, G2-Gibberellic acid 2000 ppm, G3-Seaweed extract solid...

Soil pollution by some heavy metals including: Cr, Mn, Fe, Ni, Cu, Zn, As, Mo, Cd and Pb from northern industrial area of Erbil City was assessed. The contamination indices geoaccumulation (Igeo), factor (CF), enrichment (EF), degree (Cdeg), load index (PLI) element (ECI) were applied to assess soil in North Industrial at three sites (for both surface sub-surface soils). Maximum Fe value 34243....

Essential micronutrients are required for humans to sustain proper physiological body processes and a healthy health condition. Micronutrient deficiencies, such as iron, zinc, iodine, create global concerns people. Zinc iron deficiency frequent in chickpea growing regions across the world. Bio-fortification of pulse grains, especially with Fe Zn by agronomic bio-fortification, is simplest, most...

This study determined the nutritive value of Indigoferra gerardiana, Marisine affricana, Impashion bicolor and Adhatoda vesica shrubs for ruminants. Chemical analysis revealed that dry matter (DM) content varied from 22.2% (Dodonia viscosa) to 33.6% (Debregeasia salicifolia). Maximum crude protein (19.8%) was observed for Anisomoles indica, while, neutral detergent fiber was greater (67%) in Do...
