Indeed, the group of scaling transformations acts on the solution of the system considered. But these are particular solutions. For example, in [2], such solutions are considered in a quite different context. In [1], the assertion that a vacuum domain exists is derived from the assumption that such invariant solutions are unique. Such an assertion (in form, it pretends to be a description of so...

In the present study we have evaluated the repellent activity of mixture of Curcuma longa, Zanthoxylum limonella and Pogostemon heyneanus essential oils in 1:1:2 ratio at 5%, 10% and 20% concentration against blackflies in northeastern India. Initially the essential oil mixture tested here has been found effective against Aedes albopictus mosquitoes. The average protection recorded in 20% conce...

A major technical hurdle in microfluidics is the difficulty in achieving high fidelity lithographic patterning on polydimethylsiloxane (PDMS). Here, we report a simple yet highly precise and repeatable PDMS surface micromachining method using direct photolithography followed by reactive ion etching (RIE). Our method to achieve surface patterning of PDMS applied an O2 plasma treatment to PDMS to...

Objectives: To see if dentures contaminated with Staphylococcus aureus, Pseudomas aeruginosa, Bacillus cereus, Candida albicans, and herpes simplex virus 1 could be effectively decontaminated by using Medical Tabs for Dentures. Method and materials: Ten methylmethacrylate dentures with processed soft liners (soft-liner dentures) and 10 methylmethacrylate dentures without processed soft liners (...
