It is necessary to take waterproof measures for the power supply coil and receiving used in undersea wireless transfer. We have clarified transmission characteristics of coils a waterproofed glass case. A spherical pressure-resistant suitable high-water pressure deep sea. However, there are restrictions on shape size coil, as well installation location, order install transfer system inside sphe...

Helical coil has better heat transfer rate as compared to shell and tube exchanger, Because of development secondary flow. There are so many applications where the helical is used such heating ventilation air conditioning applications, steam generators in power plants, condenser’s, reason behind using it provides large surface area per unit volume. In presented work coefficient (hi) for inside ...

Tau protein, a neuronal microtubule-associated protein, forms insoluble fibers ("paired helical filaments") in Alzheimer's disease and other tauopathies. Conflicting views on the structure of the fibers have been proposed recently, ranging from mainly alpha-helical structure to mainly beta-sheet, or a mixture of mostly random coil and beta-sheet. We have addressed this issue by studying tau fib...

This year marks the 50th anniversary of Crick's seminal paper on the packing of alpha-helices into coiled-coil structures. The central tenet of Crick's work is the interdigitation of side chains, which directs the helix-helix interactions; so called knobs-into-holes packing. Subsequent determinations of coiled-coil-protein sequences and structures confirmed the key features of Crick's model and...

The α-helical coiled-coil domain is a protein structure motif with a characteristic repeat pattern well suited for computer-based prediction. Long coiled-coil proteins play an important role in organizational and regulatory processes within cells and have been implicated in a number of human diseases. Knowledge about plant or prokaryotic long coiled-coil proteins however has been limited to a f...

Objective. To describe asymptomatic delayed migration of a coil loop in a patient following successful coil embolization of an anterior communicating artery saccular aneurysm. Methods. A 24-year-old man with a ruptured anterior communicating artery saccular aneurysm underwent coil embolization with one helical ultrasoft coil. Results. A followup CT scan head and a cerebral angiogram one month f...

BACKGROUND Transcatheter occlusion with Gianturco coils has been attempted in a small number of patients with tiny (< or = 1.5-mm diameter) patent ductus arteriosus, and preliminary results have been encouraging. The present study extends this method to larger ductus sizes and makes recommendations for proper coil size selection. METHODS AND RESULTS Coil occlusion was attempted in 24 consecut...

The dynamics of peptide α-helices have been studied extensively for many years, and the kinetic mechanism of the helix-coil dynamics has been discussed controversially. Recent experimental results have suggested that equilibrium helix-coil dynamics are governed by movement of the helix/coil boundary along the peptide chain, which leads to slower unfolding kinetics in the helix center compared w...

Stomatin is a major integral membrane protein of human erythrocytes, the absence of which is associated with a form of hemolytic anemia known as hereditary stomatocytosis. It is reported that stomatin regulates the gating of acid-sensing ion channels in mammalian neurons. However, the function of stomatin is not fully understood. In the genomic sequence of the hyperthermophilic archaeon Pyrococ...
