Amorphous powders have been synthesized by cryo-SPEX milling melt-spun ribbons at 77 K. Transmission electron microscopy reveals cryomilled magnetic nanoparticles (MNPs) with a mean diameter of 4.2 nm to form agglomerates similar to 30 nm in size. Vibrating sample magnetometer and superconducting quantum interference device magnetometry of amorphous powders reveal a specific magnetization, sigma(s), of 104 emu/g at 4 K in a 300 mT field and a T(c) of 335 K. Nanoparticles were suspended in ferrofluids by ultrasonication with a Pluronic F127 surfactant to stabilize them in aqueous solution. Ferrofluids of varying MNP concentration were rf heated in a 27.2

mT field at 267 kHz. For 1.24 vol % of MNPs in the ferrofluid, a solution reached temperatures >50 degrees click here C in similar to 70 s, and showed Curie-limiting temperature behavior at similar to 75 degrees C. These results demonstrate self-limited heating of FeCoCr MNPs at 75 degrees C which may have application in polymer curing. (C) 2010 American Institute of Physics. [doi:10.1063/1.3349043]“
“Intrauterine device (IUD) application has been used for over 30 years and is a widely accepted contraception method among women because of Birinapant mouse its low-complication rates. The use of intrauterine devices may cause complications but migration of the IUD into an adjacent organ

is rarely encountered.

In the present report, we present a 26-year-old patient to whom IUD

had been applied 2 years ago and whose examination performed due to pain and urinary complaints revealed migration of the uterine device into the bladder.

Patients with pelvic pain and chronic irritative urinary symptoms whose vaginal examination and ultrasonography reveal a dislocated IUD should be carefully examined for the migration of the IUD Sapanisertib datasheet into the bladder. In order to avoid this rare complication, patient should be evaluated physically and ultrasonographically for uterine position, thinness of the uterine wall and inflammatory disease before the insertion. The patient should be evaluated with sonography immediately after insertion and periodically.”
“In this study, wool fibers arc modified by low frequency plasma polymerization of acrylic acid regarding to its’ hydrophobic character due to cuticular cells at their surfaces. Variables of the plasma glow discharge processes were power (40-100 W) and exposure time (5-45 min). The effect of plasma modification in the performance properties of wool were investigated on the basis of hydrophilicity of wool, average wrinkle recovery angle, and breaking strength. The surface chemical structures of fabrics were examined with x-ray photoelectron spectroscopy. The hydrophobic wool fabric became hydrophilic after all plasma treatments except one (40W-5 min). Average wrinkle recovery angle of the treated fabrics were between 157 and 178, while that of untreated fabric was 180.
