Multiphase arterial spin labeling (ASL), which obtains the imaged slices with various postlabeling delays, allows for the noninvasive assessment of cerebral hemodynamics that cannot be adequately acquired by single-photon emission computed tomography (SPECT) imaging. We describe the clinical usefulness of multiphase ASL in a patient with symptomatic carotid stenosis by comparison with SPECT at ...

with respect to the high incidence of hot flash in postmenopausal women and the controversies regarding its treatment, this double-blind clinical trial was conducted to determine the effects of pimpinella anisum on hot flashes in these women referring to rural and urban health centers of qazvin province in 2009. seventy-two women with hot flashes were randomly selected according to the predeter...

A reconfigurable current mode programmable multiphase sinusoidal oscillator is realized using digitally controlled low voltage CMOS current conveyors. The realized current mode programmable multiphase sinusoidal oscillator can provide independent digital control to its oscillating frequency through n-bit control words with high resolution capability, as well as reconfigurability. The realized m...

PURPOSE To compare the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) with that of multiphase computed tomography (CT) in the evaluation of tumor response to transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC). MATERIAL AND METHODS Fifty patients (41 men, 9 women; mean age, 53 years±12.5 [SD]) with a total of 70 HCCs (mean size, 5cm±3 [SD]) were evaluated. Pos...

Three phase supply is available in the generating station or grid, were as nine phase supply is required for many industrial applications such as, aerospace, railway and automobile applications. There are different methods in which we can convert 3 to 9 phase using 18-Pulse Converter, Carrier Based PWM Technique, multilevel converter and Multiphase Transformer. The above said methods which are ...

hot flash is among the most common complaints of menopausal women, affecting their career, social activities and quality of life. this study aimed to investigate the effects of valerian on hot flashes in menopausal women. in this double blind clinical trial, 68 menopausal women with the chief complaint of hot flash were enrolled using sampling at hand and were randomly divided into drug and pla...

In this paper, the internal structure of novel multiphase gallium nitride nanowires in which multiple zinc-blende and wurtzite crystalline domains grow simultaneously along the entire length of the nanowire is investigated. Orientation relationships within the multiphase nanowires are identified using high-resolution transmission electron microscopy of nanowire cross-sections fabricated with a ...

Multiphase waterborne polymer particles provide advantages in more demanding applications, and their performance depends on particle morphology. Currently, no dynamic model for the prediction of the development of the morphology of multiphase latex particles is available. In this work, a model was developed for the prediction of the dynamic development of the morphology of multiphase waterborne...
