Hydroxyapatite (HA) was prepared from catfish bones, identified as catfish HA (CFHA), using mechanical and chemical treatment methods. CFHA was characterized by x-ray diffraction (XRD) and scanning electron microscope (SEM) techniques to confirm the presence of HA. The ability of CFHA to remove uranium (U(VI)) from aqueous phase was investigated using both batch and column experiments. Adsorpti...

BACKGROUND AND PURPOSE In clinical practice, durability of occlusion following coil embolization is superior in densely packed, compared with loosely packed, aneurysms. In a rabbit model, we probed, by using proteomics tools, the biologic mechanisms associated with densely packed and completely occluded aneurysms, compared with loosely packed and incompletely occluded aneurysms, to explore the ...

the aim of this study was to evaluate antitumour activity of the roots of hibiscus tiliaceus linn. against dalton’s ascitic lymphoma (dal) in swiss albino mice. a significant enhancement of mean survival time (mst) of h. tiliaceus treated tumour bearing mice was found with respect to control group. h. tiliaceus treatment was found to enhance peritoneal cell counts. when these h. tiliaceus treat...

A new single-carrier sensor-less pulsewidth modulation (PWM) method using suggested pseudo reference functions is proposed for packed U-cell (PUC) converter to improve performance and reliability of the PUC converter. It composed one PWM carrier signal two functions. By employing method, dc capacitor voltage ripple substantially decreased, faster balancing obtained. Moreover, power losses are e...

In tightly packed tissues, a cancer cell’s motility is linked to the shape of cell and its nucleus.

This paper investigates the performance of a seven-level Packed U Cell (PUC7) inverter-based transformerless Dynamic Voltage Restorer (DVR) topology under short-time voltage variations (voltage sags and swells). Unlike existing multilevel inverter (MLI)-based DVR solutions, proposed structure requires only one DC source (suitable for PV-based systems), capacitor, six switching devices to genera...

Main Outcome Measures: Number of packed red blood cell (PRBC) units transfused per patient. Results: A total of 332 U of PRBCs were transfused. Half of the PRBC units were administered as massive transfusions to 4.7% of the patients. The number of PRBC units transfused per patient index (PPI) was related to incident size (mean [SD], 0.70[1.60] to 1.50 [1.60]). The most frequent major blood grou...

This paper analyses a multilevel inverter configuration which provides single-phase seven-level output. topology partially adopts the packed u-cell structure and uses series connected DC sources to generate required number of output voltage levels. The DC-link capacitors are not in this topology. operating modes modulation scheme explained detail. For applications requiring high power, multilay...
