In this work we present detection and susceptibility measurement experiments on a single superparamagnetic Dynal bead with a diameter of 1 lm and a magnetic moment of _ 4 _ 108lB. Accurate bead positioning was achieved via non-invasive AFM nanomanipulation. The detection and magnetic characterization of the bead were performed using ultra-sensitive InSb Hall devices. Single bead detection was d...

PURPOSE Evaluation of doxorubicin stability over time when stored into the DC Bead embolic agent, in various containers, which are used for the delivery of the doxorubicin-loaded beads to the patients for up to 14 days under refrigerated conditions. METHODS The doxorubicin was loaded through the ionic exchange mechanism into the calibrated polyvinyl alcohol-based hydrogel beads (DC Bead), wit...

To gain more confidence in our understanding of the apparatus and analysis, we compared our experimental calibration curve to one we generated from a mathematical model of the system, following [1, 2]. The root-mean-square excursion of the projected bead location away from its tether point is controlled by various competing effects: (i) In the absence of any bead or wall, the chain’s endpoint w...

PURPOSE Instillation of sterile 1.0 microM latex beads into the central corneal epithelium renders Chinese hamsters resistant to corneal infection with Acanthamoeba castellanii. By contrast, activation of the adaptive immune response by subcutaneous immunization with A. castellanii antigens fails to protect against Acanthamoeba keratitis. This study was undertaken to examine the mechanisms that...

GAS TUNGSTEN ARC WELDING (GTAW) is the quality weld process. It is preferred welding process for stainless steel, low alloy steel, nickel, cobalt, titanium, aluminum, copper, and magnesium. The present work aims to evaluate the effect of Gas Tungsten Arc Welding process parameters on the quality of the weld bead. The process parameters Welding Current, Wire Diameter, Wire Feed Speed, Ratio of w...

Microencapsulation has become a common technique in the production of controlled release dosage forms. Many results have been reported, concerning the use of alginate beads as controlled release drug formulations. Alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. Ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

The final mechanical and physical properties should be predicted in tandem with the bead geometry characteristics for effective additive manufacturing (AM) solutions processes such as directed energy deposition. Experimental approaches to investigate are costly, simulation time-consuming. Alternative artificial intelligent (AI) systems explored they a powerful approach predict properties. In pr...

The damage that occurs around the tire bead region is one of critical failure forms a tire. Generally, prediction durability carried out by experimental method. However, it takes lot money and time to conduct experiments. Therefore, determine fatigue life radial bead, reasonable method proposed in this paper. Fatigue testing rubber compounds ΔSED-number cycle (Nf) was applied. maximum strain en...

Digestive vacuole (DV) formation in Paramecium can be separated into four steps: sequestration and recycling of the spent DV membrane, sweeping and concentrating of particles into the nascent DV, vacuole growth, and the release of the nascent DV. How the size, load and surface charge of solid particles affected formation and subsequently the digestive processes in log-phase cells were investiga...

The tire bead, as the most important load-bearing component at bead area, is closely related to durability of tire, but its structure developing slowly. For this reason, topological whole design was proposed, although it performs well, many defects existed due based on traditional experience. Therefore, paper studies topology shape optimization algorithm, delves into main criterion von Mises an...
