this paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. among common magnetic nanoparticles, magnetite (fe3o4) and maghemite (g-fe203) are popular candidates because of their biocompatibility. natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

The copolymers of cycloolefin (COC), a type thermoplastic material, have been widely used for the large-scale industrial fabrication droplet microfluidic devices, which is often performed using hot-embossing or injection-molding techniques. generation droplets and uniformity sizes are significantly affected by surface wettability COC during pressure stability employed fluid pump operation. In o...

Biological Micro-Electro-Mechanical Systems (BioMEMS) is one of the forefronts of research for adapting MEMS to meet demands for biological applications. The immense popularity of BioMEMS lies in the promise of rapid, accurate diagnostic results while requiring an exponentially lower sample volume which are achieved by replicating laboratory functionalities onto packaged miniaturized devices. T...

background: venoarterial extracorporeal membrane oxygenation (ecmo) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (lv) pressure. the aim of the present study was to investigate the adjunctive application of the impella device for lv unloading in patients during ecmo. methods: this retrospective cohort study included patie...

this study aims to examine how iranian efl learners perceive and apply mitigation devices in request speech act in 4 asymmetrical situations. role-play interactions and questionnaires were used to elicit the required data from iranian informants (male vs. female). the results obtained from the analysis of data revealed that in identical situations, male requestors were comparably more certain t...

objectives the main objective of this study was to design and construct an optical device to determine the rbv in patients undergoing hemodialysis, during the process. materials and methods after initial studies in order to select a proper sensor, using the orcad software, an analog circuit was designed. the implementation and modification of the circuit was done by the clinical tests, using ex...

background: ovarian pregnancy is a rare form of the non-tubal ectopic pregnancy. it ends with rupture before the end of the first trimester. one of the important risk factors for ovarian pregnancy is in the use of intra uterine devices (iud). case:  we report here one such uncommon case of ovarian ectopic pregnancy. our patient is a 30 years old multiparous woman with two previous cesarean sect...

Ubiquitous systems provide users with various possibilities of interacting with applications and components using different modalities and devices. To offer the most appropriate mode of interaction in a given context, various types of sensors are combined to create interactive applications. Thus, the need for integrated development and evaluation of suitable interaction concepts for ubiquitous ...
