We created a coke-repellent inner surface in stainless steel (SS-321) tube using an enhanced chemical etching tactic. A water-borne solution was formulated by combining ion sequestering ligand (L), hydrogen peroxide (H), hydrochloric acid (C), and stabilizing agent (E or N). Three etchants, LHC, LHC-E, LHC-N, were therefore formulated, respectively. The metal surfaces achieved these etchants al...

[Purpose] The purpose of this study was to investigate the difference in task performance, grip and pinch strength, and dexterity with and without cock-up splints, which are widely used in occupational therapy practice. [Methods] Twenty-three participants performed Jebsen-Taylor hand function test and grooved pegboard for task performance and dexterity. The power grip and pinch strength was mea...

OBJECTIVE Neuropsychological dysfunction is common in patients with idiopathic normal pressure hydrocephalus (iNPH). Shunt treatment is beneficial, some patients reaching complete or almost complete recovery, while others show only minor improvement. We aimed to assess the efficacy of a small selection of well characterized and sensitive neuropsychological tests in the context of the European m...

Circulating tumor cells (CTCs) in peripheral blood have been recognized as a general biomarker for diagnosing cancer and providing guidance for personalized treatments. Yet due to their rarity, the challenge for their clinical utility lies in the efficient isolation while avoiding the capture of other non-targeted white blood cells (WBCs). In this paper, a wavy-herringbone (HB) microfluidic chi...

Olfactory receptors in basiconic and grooved-peg sensilla on the antenna of fifth-instar Triatoma infestans nymphs respond to host odours. Gas chromatography analyses of host odour extracts coupled to electrophysiological recordings from basiconic sensillum receptors indicate that nonanal is a constituent of sheep wool and chicken feather odour that stimulates one of the receptors in this type ...

Abstract A heat pipe is a conduction program that utilizes both permeability and regime shift concepts to transport effectively between 2 different lines. made up of or tube base fluid. In practice, the poured into mould compatible with cooling media. These devices have found uses in variety fields, including space apparatus, solar energy systems, electronic equipment, air conditioning due thei...

Contact guidance refers to the reactions of cells with the topography of their substratum. Current hypotheses on the mechanism of contact guidance focus on the dynamic behaviour of the cytoskeletal components, but most observations have been made on cells that have already become oriented with topographic features of the substratum. The purpose of this study was to examine the sequence in which...

Results determined the upper limit for impact velocity of bouncing droplets on micro-grooved surfaces.

The purpose of the study was to evaluate the capacity of an expanded set of force steadiness tasks to explain the variance in the time it takes young men and women to complete the grooved pegboard test. In a single experimental session, 30 participants (mean ± SD) (24.2 ± 4.0 yr; 15 women) performed the grooved pegboard test, two tests of hand speed, measurements of muscle strength, and a set o...
