The application of microfluidics to biomedicine has been touted [1] as a means to deliver improved and inexpensive medical care. Though there are many methods for transporting fluids within these devices [2], from the passive capillary forces that draw a fluid along a hydrophilic channel to the actively driven forces like electrophoresis, none would appear to be as powerful as surface acoustic ...

Surrogate mixtures are routinely used for understanding gasoline fuel combustion in engine simulations. The general trend surrogate formulation has been to increase the number of components a mixture better emulate real properties. Recently, new design strategy based on functional group analysis gasolines was proposed using minimal species [minimalist (MFG)—approach]. MFG surrogates (having jus...

This study proposes a low-cost, portable paper-fluidic vertical flow assay bacterium counter with high accuracy. We designed sensors low fabrication costs based on e-beam evaporation and three-dimensional printing the impedance measurement principle. Interdigitated (IDT) electrodes were coated filter membrane by shadow mask. could print wafer-scale frames melting temperature three-dimensional-p...

Scientific achievement in molecular biology and genetic engineering have made it possible to create new methods of selection k that are based on genome modification. Todays, more genetically modified plants being intensively tested the field, but their influence has not yet been fully studied environment, biodiversity, human health, animal body.

Intensity diffraction tomography (IDT) refers to a class of optical microscopy techniques for imaging the three-dimensional refractive index (RI) distribution sample from set two-dimensional intensity-only measurements. The reconstruction artefact-free RI maps is fundamental challenge in IDT due loss phase information and missing-cone problem. Neural fields has recently emerged as new deep lear...

A bio-compatible disposable organic humidity sensor has been fabricated that can be transferred to any arbitrary target surface. Single cell thick onion membrane has been used as the substrate while it also doubles as the active layer of the sensor. Two different types of sensors were fabricated. In type-1, the membrane was fixed into a plastic frame with IDT patterns on one side while the othe...

Thermogravimetric analysis was carried out to investigate the thermal degradation of High Density Poly Ethylene (HDPE) short fibers reinforced epoxy composites. Three composites with 5, 10 and 15 % by weight of HDPE short fiber composition were prepared using epoxy as matrix material. The HDPE short fiber used as reinforcing material into the resin helps in retarding the thermal degradation of ...

Clinical observations have shown that some older patients are unable to learn to use a metered dose inhaler (MDI) despite having a normal abbreviated mental test (AMT) score, possibly because of dyspraxia or unrecognised cognitive impairment. Thirty inhaler-naive inpatients (age 76-94) with an AMT score of 8-10 (normal) were studied. Standard MDI training was given and the level of competence r...

In this paper, we present a novel microelectromechanical system-interdigital transducer (MEMS-IDT) surface acoustic wave (SAW) gyroscope with an 80MHz central frequency on a 128 YX LiNbO3 wafer. The developed MEMS-IDT gyroscope is composed of a two-port SAW resonator, a dual delay line oscillator, and metallic dots. The SAW resonator provides a stable standing wave, and the vibrating metallic d...

In the present study, large-eddy simulations (LES) are used to identify underlying mechanism that governs ignition phenomena of spray flames from different nozzle diameters when ambient temperature (Tam) varies. Two sizes 90µm and 186µm chosen. They correspond by Spray A D, respectively, in Engine Combustion Network. LES studies both nozzles performed at three Tam 800K, 900K, 1000K. The numeric...
