Recent advances in microwave ferrite device technology have seen the introduction of superconductivity that virtually eliminates insertion losses due to electrical conduction in microstrip circuits. The conventional ferrimagnetic spinel and garnet compositions, however, are not generally optimized for temperatures in the vicinity of 77 K and may require chemical redesign in order to realize the...

Abstract The large fall in global output and massive job losses during the current pandemic is creating a socio-economic upheaval that likely to persist over time. From previous crises, we know some of their effects are leave permanent scars through what known as hysteresis. This article discusses how concept scarring or hysteresis relevant for pandemic-induced economic crisis. We discuss chann...

BACKGROUND Few objective measures have been used to document change in myofascial tissues after OMT. HYPOTHESIS Paraspinal tissues associated with cervical somatic dysfunction (SD) will demonstrate quantifiable change in myofascial hysteresis characteristics after a given OMT technique but not after a Sham intervention. MATERIALS & METHODS 240 subjects were palpated for cervical articular S...

In electrical machines, iron losses are essential for electromagnetic and thermal designs and analyses. Although many models have been proposed to predict iron losses in magnetic materials, the calculation of iron losses under non-sinusoidal excitations is still an open field. Most works concern the influences of the value, the change rate or the frequency of flux density in the frequency domai...

Thin films of HfO2 produced by pulsed-laser deposition on sapphire, yttria-stabilized zirconia, or silicon substrates show ferromagnetic magnetization curves with little hysteresis and extrapolated Curie temperatures far in excess of 400 K. The moment does not scale with film thickness, but in terms of substrate area it is typically in the range 150–400 B nm −2. The magnetization exhibits a rem...

Rapid-solidification method was applied to make Fe-15at%Ga and Fe-17at%Ga ribbons of 100 μm thickness. These ribbons have large magnetostriction of 270 ppm, where the coercive force exhibits a maximum value. The phenomenon is related to special metallic texture, that is, the ribbon has strongly [001]-oriented textured fine columnar microstructure with grain size of 2~5 μm. The ribbon has little...

OBJECTIVES/HYPOTHESIS Bacterial biofilms (BBF) and osteitis are potential contributors to the local inflammatory load in chronic rhinosinusitis (CRS). This study investigated the relationship between BBF and osteitis status in CRS patients. STUDY DESIGN Prospective cohort study. METHODS Eighty-four CRS patients undergoing endoscopic sinus surgery and 22 control patients were enrolled in thi...

The effect of chitosan coating combined with green tea extract (GTE) on the quality of tigertooth croaker (Otolithes ruber) fillets including chemical, microbiological, texture, color and sensory properties during 16 days of refrigerated storage was investigated. The changes of color different were significantly retared, and the texture parameteres and sensory scores were significantly improved...
