high nitrogen and plant density cause increasing vegetative growth and reducing harvest index. the objective of this study was to evaluate the effect of cycocel at high nitrogen and plant density on safflower yield and yield components. for this purpose a field experiment was carried out as a factorial-split plot based on randomized complete block design with three replications with esfahan 14 ...

Accuracy of the electron's atomic mass has been improved tenfold by comparing cyclotron frequencies of electrons and single C + ions alternately confined to the same uniform magnetic field in a Penning trap. Cyclotron resonances are observed via frequency shifts in the particle's continuously monitored harmonic motion parallel to the field. Field instability and relativity cause, respectively, ...

I n t e r v e n t i o n Patients were allocated to once-daily losartanbased therapy (n = 660) or atenolol-based therapy (n = 666) with hydrochlorothiazide as the second agent in both groups to reach a target systolic BP < 140 mm Hg. M a i n o u t c o m e m e a s u r e s A composite endpoint of cardiovascular mortality, myocardial infarction (MI), and stroke. Secondary outcomes included all-caus...

Every time the heart beats, increases and decreases in cytosolic free Ca ([Ca]cyto) switch on and off the mechanochemical reaction that produces movement and force. These [Ca]cyto transients are generated by the interplay of several different mechanisms, including (1) Ca entry into the cell (largely via CaV1.2 channels), (2) Ca release from the SR (a specialized intracellular organelle), and (3...

in order to evaluate plant density and different nitrogen levels on protein percent, yield and nitrate accumulation in potato tuber cv. agria, a factorial experiment based on randomized complete block design with three replications was conducted in ardabil in 2006. factors included nitrogen levels: 0, 80, 160 and 200 kg ha-1 net nitrogen and plant densities: 5.5, 7.5 and 11 plant m-2. results s...

A variant of the multidrug-resistant human sarcoma cell line Dx5 was derived by co-selection with doxorubicin and the cyclosporin D analogue PSC 833, a potent inhibitor of the multidrug transporter P-glycoprotein. The variant DxP cells manifest an altered phenotype compared with Dx5, with decreased cross-resistance to Vinca alkaloids and no resistance to dactinomycin. Resistance to doxorubicin ...
