Abstract We report here a comparative study of the effects La-substituted Ca on (Bi, Pb):2212 and Pb):2223 superconductors with various La content (0.00 ≤ x 0.30). Regardless La, it is evident that superconducting volume fraction, excess oxygen, critical concentration for quenching superconductivity, Vickers hardness, anisotropy, interlayer coupling, magnetic fields, current were higher 2212 se...
Two millimeter observations of the MACS J1149.6+2223 cluster have detected a source that was consistent with the location of the lensed MACS 1149-JD galaxy at z = 9.6. A positive identification would have rendered this galaxy as the youngest dust forming galaxy in the universe. Follow up observation with the AzTEC 1.1 mm camera and the IRAM NOrthern Extended Millimeter Array (NOEMA) at 1.3 mm h...
This research aimed to analyse the effect of biopesticide and organic liquid fertilizer on weight and quality of apple. The study was carried out in Bumiaji, Batu, East Java (805'S, 11280'E, 1400 m in altitude) on July December 2013. The liquid organic fertilizer (LOF) was produced from water mixed with nitrogen source such as manure, urin, legume leaves, phosphoric powder and an energy sourc...
A pot culture experiment was carried out to study the alterations in growth, biochemical activities and cadmium (Cd) uptake by wheat (Triticum aestivum) inoculated with or without arbuscular mycorrhizal (AM) fungi in sterilized soil with addition of different Cd levels (0, 100, 300, 600 mg.kg_1). In Mycorrhizal (M) plants, root colonization rates were significantly lower with the addition of hi...
در این پایان نامه به ساخت و تحلیل 4 نمونه از ابررساناهای حجمی bscco با نام¬های c, b, a و d پرداخته می¬شود که سه نمونه اول آن¬ها به روش واکنش حالت جامد و نمونه آخر به روش سل ژل ساخته شده است. سپس اثر ماکروفر بر روی دو نمونه b و c بررسی شده و در انتها از نمونه b سیم ابررسانا به روش pit ساخته شده است. نمونه a با استوکیومتریbi1/89pb0/41sr2/01ca2/23cu3/03ox طی دو مرحله در دماهای 700 و 800 تکلیس و ...
