The creep-fatigue interaction has been recognized as the main failure mode of most structural components operating in high-temperature regime. cyclic life (Nf) usually decreases continuously with dwell time their interactions. However, Nf shows an abnormal change, i.e. keeps constant or slightly increases/decreases, present studied Nickel-based superalloy, DZ445. This means that generalized “Nf...

The current study emphasizes the synthesis of iron oxide nanoparticles (IONPs) and impact of hydrophilic polymer polyvinyl alcohol (PVA) coating concentration as well as anticancer drug doxorubicin (DOX) loading on saturation magnetization for target drug delivery applications. Iron oxide nanoparticles particles were synthesized by a reformed version of the co-precipitation method. The coating ...

Two series of magnesium-manganese ferrites, viz., Mgo.9Mn0.iInxFe2_x04 and Mgo.9Mn0.iCrJ,Fe2_J,04 have been prepared using conventional ceramic technique. Magnetic properties such as saturation magnetization (Ms), Curie temperature (Tc), initial permeability (mi), and magnetic loss factor (tan d), of the above series of samples are presented in this paper. Ms value increases slightly up to a ce...

The temperature variation of magnetic anisotropy and coercive field of magnetoelastic manganese-substituted cobalt ferrites CoMnxFe2−xO4 with 0 x 0.6 was investigated. Major magnetic hysteresis loops were measured for each sample at temperatures over the range 10–400 K, using a superconducting quantum interference device magnetometer. The high-field regimes of the hysteresis loops were modeled ...

OBJECTIVES Video-surgery in neonates is recent. Data on the respiratory, hemodynamic, and thermic effects during the first month of life are still sparse. This study aimed to evaluate the tolerance of video-surgery in neonates and to determine the risk factors of per-operative complications. METHODS From 1994 to 2004, 49 neonates (mean age: 11 days; weight: 3285 g) underwent 50 video-surgical...

This experimental work investigates the hydraulic behavior of a macro-cracked concrete, in order to improve the understanding of the coupled effects of temperature and water saturation. A concrete sample is macro-cracked using the Brazilian test technique. It is then submitted to dry or wet gas flow at different temperatures and confining pressures and its permeability is recorded. This first p...

The purpose of this paper is to show how an ear oximeter can be used to measure the oxygenation of the blood by the lungs with much greater discrimination than is generally appreciated. There are three stages: the first is to calibrate the oximeter by a practicable method; the second is to use the instrument to construct an oxygen dissociation curve; and the third is to minimize an important so...

Epitaxial ferrimagnetic thin films of (Co, Ru) Fe2O4 were grown on MgO (001) substrate using pulsed laser deposition technique. Ruthenium substitution in cobalt ferrite has increased the conductivity by orders magnitude, but it a minimal effect magnetic properties. The film high coercivity and perpendicular anisotropy (PMA), where easy axis points to surface. We report electrical transport prop...

background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...

In studies of fine magnetic particle systems, saturation remanence is often measured during warming from liquid helium temperature in order to determine the distribution of blocking temperatures. These data have usually been treated as if they are unaffected by magnetic interactions. However, this treatment is often inconsistent with the experimental data. Furthermore, the thermal decay of satu...
