Magnetization mechanisms of nanoscale magnetic grains greatly differ from well-known magnetization mechanisms of micrometer- or millimeter-sized magnetic grains or particles. Magnetization switching mechanisms of nanoscale exchange-coupled composite (ECC) grain in a microwave field was studied using micromagnetic simulation. Magnetization switching involving a strongly damped or precessional os...

The field induced magnetic phase transitions of Cs2CuBr4 were investigated by means of magnetization process and neutron scattering experiments. This system undergoes magnetic phase transition at Neél temperature TN = 1.4K at zero field, and exhibits the magnetization plateau at approximately one third of the saturation magnetization for the field directions H ‖ b and H ‖ c. In the present stud...

I wish to comment on the limitations of an automated remnant lipoprotein cholesterol (RemL-C) assay reported in Clinical Chemistry (1 ). Remnants are lipoprotein particles produced after newly formed triglyceride-rich lipoproteins (TRLs) of either hepatic or intestinal origin enter the plasma space and undergo lipolysis via the action of lipoprotein lipase in the capillary bed. During this proc...

PURPOSE To determine whether magnetization transfer contrast can differentiate acute from chronic lesions in multiple sclerosis. METHODS Thirteen patients with multiple sclerosis and eight healthy patients were studied with MR using a 0.1-T system. Relatively T2-weighted spin-echo images were obtained without and with magnetization transfer contrast. The magnetization transfer effect of multi...

PURPOSE To establish a normal baseline of the percent magnetization transfer of gray (cortical and deep) and white matter structures in the brain in healthy adults and to determine whether there are adult age-related differences in these measurements. METHODS Axial T1-weighted scans (800/20 [repetition time/echo time]) with and without magnetization transfer were prospectively performed on a ...

iron oxide nanoparticles were synthesized by coprecipitation method using ammonia as precipitation agent. most researchers usually add ammonia into the iron salt solution but in this work the salt solution drop wise has been added to the ammonia and the new obtained results were compared with those of other researches. magnetic properties of nanoparticles were measured by vsm. the effect of rea...

Multiferroic materials with good magneto-electric coupling are of great interest due to their enormous applications in the field spintronic devices. Magnetoelectric (ME) gallium ferrite is an interesting material its room temperature (RT) piezoelectricity and near RT ferrimagnetism along significant ME (10 −11 s/m at 4.2 K). The work aims increase magnetic transition (T C ) above so that can ha...

A few cases of laparoscopic surgery for urachal remnant in children has been reported in English literature. With recent developments in minimal invasive surgery, laparoscopic approach for urachal remnant in adulthood is recommended by some laparoscopic surgeons because of its technical feasibility and safety as well as cosmesis. Recently we experienced a case of complicated urachal remnant in ...

The supernova remnant N157B (30 Dor B, SNR 0539-69.1, NGC 2060), located in the Tarantula Nebula of the Large Magellanic Cloud, has long been considered a possible Crab-like remnant. This hypothesis has been confirmed, quite spectacularly, with the discovery of PSR J0537−6910, the remarkable 16 ms X-ray pulsar in N157B. PSR J0537−6910 is the most rapidly spinning pulsar found to be associated w...
