Correspondence MEDIALJOUH How much easier it would be if platelet stickiness were expressed as the percentage of sticky platelets rather than as the percentage of non-sticky platelets, and how much more logical. That is: Platelet stickiness (%)= (Original Count minus Second Count) x 100 Original Count With this simple transformation a high value would indicate a high degree of sticki-ness, and ...

We present experimental evidences for the existence of a semi-hard scale in light hadrons. This includes the suppression of gluon radiation that is seen in high mass hadron diffraction; the weak energy dependence of hadronic total cross sections; the small value of the Pomeron trajectory slope measured in photoproduction of J/Ψ; the weakness of gluon shadowing in nuclei; shortage of gluons in t...

When two drops of radius R touch, surface tension drives an initially singular motion which joins them into a bigger drop with smaller surface area. This motion is always viscously dominated at early times. We focus on the early-time behavior of the radius rm of the small bridge between the two drops. The flow is driven by a highly curved meniscus of length 2πrm and width ∆ ≪ rm around the brid...

Most cloud radiation models and conventional data processing techniques assume that the mean number of drops of a given radius is proportional to volume. The analysis of microphysical data on liquid water drop sizes shows that, for sufficiently small volumes, this proportionality breaks down; the number of cloud drops of a given radius is instead proportional to the volume raised to a drop size...

The effect of density ratio on the hydrodynamic interaction between two drops in simple shear flow at finite Reynolds numbers is studied considering the gravity influence. In this study the full Navier-Stokes equations are solved by a finite difference/front tracking method. The interaction of two drops contains approach, collision, and separation. For a range of density ratios, the interaction...

We describe a single microfluidic device and two methods for the passive storage of aqueous drops in a continuous stream of oil without any external control but hydrodynamic flow. Advantages of this device are that it is simple to manufacture, robust under operation, and drops never come into contact with each other, making it unnecessary to stabilize drops against coalescence. In one method th...

The aim of the studies was to determine the stability of metronidazole using UV spectrophotometric method in 0.5% w/w eye drops which were prepared under aseptic conditions and thermally sterilized. 0.9% solution of NaCl, 5% glucose and phosphate buffers of pH 6.97 and 6.81 were used as the solvents of metronidazole in the drops. Thiomersal and phenylmercuric borate were used to preserve the dr...

The effective use of aqueous and oily pilocarpine was studied in 19 glaucomatous eyes. The aqueous drops were used 4 times a day while the oily drops were used only twice. It was found that the oily drops were better than the aqueous drops in lowering the mean intraocular pressure and the maximum pressure reached during the day. no statistically significant difference was found between the 2 pi...

Fluid drops coated with particles, so-called Pickering drops, play an important role in emulsion and capsule applications. In this context, knowledge of mechanical properties and stability of Pickering drops are essential. Here we prepare Pickering drops via electric field-driven self-assembly. We use direct current (DC) electric fields to induce mechanical stress on these drops, as a possible ...
