This research reported a new method of removal of Pb+2from water by using a nano zero valent iron (nZVI) assisted ultrasonic wave. At first, nZVI was synthesized by an ultrasound assisted method. Particles morphology and surface composition were characterized by FESEM, XRD, and EDX. The XRD patterns showed that the crystallinity of the nZVI prepared using ultrasonic conditions was hi...

In the present study, ultrasound-assisted extraction of oil from rice bran was investigated through response surface methodology (RSM), where process variables were amplitude level (50–100%) and sonication time (5-30 min). It was found that all process variables had significant (p<0.05) effects on the response variable. A central composite design (CCD) was used to determine the optimum process ...

conclusion lumbar medial branch nerve block under ultrasound guidance was associated with high rates of treatment success and excellent treatment outcomes for facet joint pain. it is also feasible and administers no radiation. thus, ultrasound-guided procedures can be used instead of conventional methods. results the success rate was 98% (87/89 blocks), which was due to our use of ultrasound gu...

BACKGROUND Ultrasound-aided fixation is a recently developed alternative method of treatment of zygomatico-maxillary (ZM) fracture, and it can resolve the problems of excessive torsion force and subsequent fractures of screws. We conducted this study to evaluate the clinical usefulness of ultrasound-aided fixation as compared with the conventional fixation method using a drill and an expander i...

Most burns are thermal and can be treated on an outpatient basis with conventional care that includes daily dressing changes, debridement, and infection control. These treatments can exacerbate pain associated with burns. Noncontact, low-frequency, nonthermal ultrasound therapy is delivered via sterile saline mist and has been used to cleanse and debride a variety of acute and chronic wounds, i...

The vitreous body is nearly transparent both optically and ultrasonically. Conventional 10- to 12-MHz diagnostic ultrasound can detect vitreous inhomogeneities at high gain settings, but has limited resolution and sensitivity, especially outside the fixed focal zone near the retina. To improve visualization of faint intravitreal fluid/gel interfaces, the authors fabricated a spherically curved ...

Conventional Canny edge detector can detect edges in image with additive noise effectively but not ultrasound image that are corrupted by multiplicative speckle noise which alleviates image resolution resulting in inaccurate characterization of object features. In this paper, we proposed to incorporate the modified SRAD into the Canny edge detector to replace the Gaussian blurring in the conven...

This work examined the effect of mixing time on three different flour dough systems: bread-flour wheat dough, all-purpose flour wheat dough, and cake flour wheat dough. Both ultrasound and conventional rheology techniques were used to examine the effect of mixing on these dough systems. Fundamental ultrasound results were obtained at 3.5 MHz; velocity and attenuation showed peak values at the o...

The present is a retrospective study examining the use of automated breast volume scanner (ABVS) for guiding breast conservation surgery in ductal carcinoma in situ (DCIS). A total of 142 patients with pathologically confirmed DCIS were initially included in the study. The patients underwent preoperative examination by conventional ultrasound and by ABVS. The BI-RADS category system was used to...
