In this study, the effects of mesa dimensions on sensor response in diaphragm-based Fabry-Perot fiber optic sensors (FOSs) were investigated detail. Mesa diaphragms, also called center-embossed have been discussed sufficiently literature, but effect thickness performance has not Moreover, there is no precise analytical solution for such diaphragms. For reason, diaphragms with different thicknes...

in this paper, the axisymmetric corrugated diaphragm using finite element method will be discussed, so that half of these diaphragms’ cross sections and later the applied pressure will be considered. following this, using the consequent equations and visual basic software, a computer program will be provided which receives the diaphragms’ particulars such as diameter, thickness, pressure and th...

A series of active piezoelectric diaphragms were fabricated and patterned with several geometrically defined Inter-Circulating Electrodes "ICE" and Interdigitated Ring Electrodes “IRE”. When a voltage potential is applied to the electrodes, the result is a radially distributed electric field that mechanically strains the piezoceramic along the Z-axis (perpendicular to the applied electric field...

Diaphragms of mice were traumatized by division parallel or transversally to the muscle fibres. The extent of traumatization was varied by the degree of subdivision. Oxygen uptake was measured by the Warburg technique. Undivided diaphragms as control displayed constant oxygen uptake for the four hours of observation. With divided diaphragms oxygen uptake was unstable. Division parallel to the m...

In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...

We assessed how often bedside stethoscopes in our intensive care unit were cleaned and whether they became colonised with potentially pathogenic bacteria. On two separate days the 12 nurses attending the bedspaces were questioned about frequency of stethoscope cleaning on the unit and the bedside stethoscopes were swabbed before and after cleaning to identify colonising organisms. Twenty-two he...

To investigate the chemical nature of the cationic ferritin (CF)-binding sites of the differentiated microdomains of the capillary endothelium, the vasculature of the mouse pancreas and intestinal mucosa was perfused in situ with neuraminidase, hyaluronidase, chondroitinase ABC, heparinase, and three proteases: trypsin, papain, and pronase. Proteases of broad specificity removed all anionic sit...

Objectives: The diaphragm, a woman controlled, reusable contraceptive device, might prevent some sexually transmitted infections (STIs). We assessed the acceptability and feasibility of use of silicone WideSeal Arcing Diaphragms (Milex Products, Chicago, IL, USA) by sex workers in Madagascar. Methods: Over 8 weeks, we evaluated method acceptability by examining patterns of and problems with wom...

Nitric oxide (NO) acts as an endogenous mediator in mature skeletal muscle. In this study, we investigated the regulation of the endothelial (eNOS) and neuronal (nNOS) isoforms of nitric oxide synthase (NOS) in skeletal-muscle development (rat diaphragm). Muscle NOS activity, nNOS and eNOS protein, and mRNA expressions were markedly increased during the late gestational and early postnatal peri...
