We demonstrate self-aligned liquid crystals (LCs) using a wrinkled-wall polydimethylsiloxane (PDMS) wrinkle structure, which is a key factor to obtain a stable homogeneous alignment state with positive LCs. We constructed the wrinkled walls via localised surface exposure to IB radiation, which passed through a long length localised pattern mask. The creation of the wrinkled wall helped to align...

semi-rigid aluminum containers are being used widely in food industries. they have wrinkle shaped walls for strengthening their physical structure. the objective of this study was to assess the effect of wrinkled parts on the heat transfer and temperature distribution of the containers by computational fluid dynamics (cfd) analysis. therefore, a precise designed geometry of the wrinkled walls c...

Background: The accurate differentiation of perinatal torsioned ovarian cysts (PTOCs) in neonates is of utmost importance. This importance is due to the fact that if PTOCs are diagnosed properly, minimally invasive or conservative management approaches can be offered. The present study aimed to describe the ultrasound findings of PTOCs and compare the results with pathological findings.Me...

Nine strains of the Gram-negative bacterium, Acinetobacter, showed a wide variation in resistance to ionizing radiation; all gave sigmoid survival curves, with D10 values for the exponential portion ranging from 70 to 460 J kg"" (7-46 krd). The fine structure of these strains was studied by electron microscopy. Results for a resistant strain were described earlier and the present paper gives co...

BACKGROUND A leaf cuticle has different structures and functions as a barrier to water loss and as protection from various environmental stressors. METHODS Leaves of Panax ginseng were examined by scanning electron microscopy and transmission electron microscopy to investigate the characteristics and development of the epicuticular structure. RESULTS Along the epidermal wall surface, the un...

Prune Belly syndrome (PBS) is a rare congenital anomaly and is almost exclusive to males. We are reporting 2 cases of PBS. The first case of 8 days old baby born to a mother (29 years) who has history of such child previously but unfortunately that baby didn’t survive and died at 1.5 years of age. On physical examination child had wrinkled skin over abdomen showing signs of deficient abdominal ...

A method for simultaneously patterning and functionalizing thin poly(2-hydroxyethyl methacrylate) films through a reactive silane infusion based wrinkling is developed. Wrinkled patterns with tunable wavelengths on submicrometer size are easily produced over large area surfaces and can express a wide variety of chemical functional groups on the surface. The characteristic wavelength of wrinklin...
