The paper by Syed et al, 1 provides observations on the use of face masks by members of the public for protection against the severe acute respiratory syndrome (SARS) corona-virus (CoV). The authors' raise an important question as to whether masks are effective in preventing disease. The type of masks used can generally be categorised as either surgical or paper and are suggested to offer simil...

A granular droplet that is composed of smaller and denser particles in a bed larger lighter found to sink split when subjected combination vibration fluidizing gas flow. Despite visual similarities with fluid-like instabilities, the observed phenomenon result particulate character matter. Combining experiments numerical simulations, we show high-density causes formation an immobilized zone obst...

Abstract Some true bug species use droplet-shaped, open-capillary structures for passive, unidirectional fluid transport on their body surface in order to spread a defensive protect themselves against enemies. In this paper we investigated if the shape of found bugs (bug-structure) could be optimised with regard better performance transportation. Furthermore, kind structure technical applicatio...

objective(s):investigation of phase diagram of various drug formulations is effective to predict different phase region of drugs to detect final formula. the purpose of this research was to develop the ternary phase diagrams for a drug microemulsion system consisting of cucurbita pepo (pumpkin) oil, surfactant (tween 80) and deionized water. materials and methods:an electrical conductivity was ...

Combinatorial droplet microfluidic devices with programmable microfluidic valves have recently emerged as a viable approach for performing multiplexed experiments in microfluidic droplets. However, the serial operation in these devices restricts their throughput. To address this limitation, we present a parallelized combinatorial droplet device that enhances device throughput via droplet bifurc...

The surface flows on a droplet in an oscillating pressure field are simulated numerically by solving the Navier-Stokes equations using the Arbitrary Lagrangian-Eulerian and level set coupled method. Detailed transient flow fields in and around the droplet are calculated by performing parallel computations, and the flow phenomena in a thin layer around the droplet surface are discussed. The reci...

The PAT family proteins, named after perilipin, adipophilin, and the tail-interacting protein of 47 kDa (TIP47), are implicated in intracellular lipid metabolism. They associate with lipid droplets, but how is completely unclear. From immunofluorescence studies, they are reported to be restricted to the outer membrane monolayer enveloping the lipid droplet and not to enter the core. Recently, w...

A quantitative description of the dynamics of droplet motion has been a long-standing concern in electrowetting research. Although many static and dynamic models focusing on droplet motion induced by electrowetting-on-dielectric (EWOD) already exist, some dynamic features do not fit these models well, especially the dynamic saturation phenomenon. In this paper, a dynamic saturation model of dro...

Air quality plays a significant role during the coronavirus pandemic. acts as spreading media well control measure for infection in polluted spaces. Insufficient ventilation around building may lead to rise of pollutants carrying virus. One way improve is by increasing air change rate. This study investigates rate effectiveness reducing droplets classroom. Cases with various layouts inlet and o...

Accurate and precise nucleic-acid quantification is crucial for clinical and diagnostic decisions, as overestimation or underestimation can lead to misguided treatment of a disease or incorrect labelling of the products. Digital PCR is one of the best tools for absolute nucleic-acid copy-number determination. However, digital PCR needs to be well characterised in terms of accuracy and sources o...
