Axial Vibration Characteristics of a Metal Diaphragm Coupling
Applied Mechanics and Materials, 2012 In this article, a metal diaphragm coupling is introduced. It is assembled by interference fit with the shafts. Based on two axial vibration styles, self-exited vibration and external exited vibration, of the coupling, physical model of the coupling is established. Stiffness and damping of the coupling are also solved and analyzed.

Diaphragm Couplings Versus Gear Couplings for Marine Applications
Marine Technology and SNAME News, 1988 The gear coupling has been in existence for over 50 years. As advances in marine propulsion have occurred, so have advances in gear couplings. There are many variables in gear couplings that can affect their characteristics, including tooth design, materials, and lubrication methods. All couplings react on connected equipment.

Acetylcholine contracture and excitation-contraction coupling in denervated rat diaphragm muscle
Pfl�gers Archiv European Journal of Physiology, 1973 Acetylcholine (ACh) contracture of chronically denervated rat diaphragms were studied under different conditions which affect electromechanical coupling. 1. Acetylcholine induced a transient contracture while the membrane potential and the twitch amplitude remained depressed as long as the drug was present. 2.

Introduction of an Economical Diaphragm Coupling for Mid-Range Applications
Volume 6: 8th International Power Transmission and Gearing Conference, 2000 Abstract This paper discusses the design, development, and testing of the NC diaphragm coupling. It also outlines the advantages of this coupling and its use in various applications. Non-lubricated couplings have become commonplace in the Power Transmission Industry.

Coupling of waveguide with resonator through diaphragm with slot with dielectric slab
2017 XI International Conference on Antenna Theory and Techniques (ICATT), 2017 The problem of coupling of a semi-infinite rectangular waveguide with a resonator through the narrow slot in their common end wall is solved. The slot is completely or partially filled with a dissipative dielectric. The changes in the behavior of the reflection and absorption coefficients of the feeding power are studied as a function of the dielectric

Couples' acceptability of the SILCS diaphragm for microbicide delivery
Contraception, 2012Disposable plastic applicators used in microbicide gel studies are expensive and have a negative environmental impact. The SILCS diaphragm is a barrier contraceptive that could offer a reusable delivery system.Thirty-six couples in this randomized, cross-over study evaluated single- and double-sided gel delivery from a SILCS diaphragm compared with gel

Nitric Oxide Modulates Excitation-Contraction Coupling in the Diaphragm
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 1998We investigated the enzymatic source, cellular production, and functional importance of nitric oxide (NO) in rat diaphragm. Neuronal and endothelial isoforms of constituitive nitric oxide synthase (nc-NOS, ec-NOS) were identified by immunostaining. NOS activity measured in diaphragm homogenates averaged 5.1 pmol/min/mg.

Effect of Lung Volume Reduction Surgery on Neuromechanical Coupling of the Diaphragm
American Journal of Respiratory and Critical Care Medicine, 1998The mechanisms for symptomatic improvement following lung volume reduction surgery for emphysema are poorly understood. We hypothesized that enhanced neuromechanical coupling of the diaphragm is an important factor in this improvement. We studied seven patients with diffuse emphysema before and 3 mo after surgery.
