The inadequate seismic performance of existing masonry buildings is often linked to the excessively low in-plane stiffness timber diaphragms and poor quality their connections walls. However, relevant past studies events have also shown that rigid could be detrimental for do not necessarily lead an increase in performance. Therefore, this work explores opportunity optimizing retrofitting floors...

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 Wide-Seal 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 wo...

The effect of epinephrine and glucagon on W02 production from C-l-labeled branched chain amino acids, [I-W]pyruvate, [1-Wlalanine, and [U-14Clglucose, was studied in isolated diaphragms and petiused hearts. The tissues were obtained from rats fed ad libitum or fasted for 48 hours. Epinephrine (10m4 M) stimulated *4CO~ production from Ieuciue, valine, and alanine by hemidiaphragms of fasted rats...

Micromachined microphones that use a diffraction-based optical method for integrated interferometric detection of diaphragm displacement are described. With optoelectronics integration, this approach yields highly sensitive microphones in mm-cube volumes. Furthermore, the electrical port of the device, which is freed by optical detection, is used for electrostatic actuation of the microphone di...

Expression of aquaporin (AQP) 4 in the surface membranes of skeletal myofibers is well established; however, its functional significance is still unknown. The alterations of AQP4 expressions in dystrophic muscles at RNA and protein levels have been reported in various dystrophic muscles such as dystrophinopathy, dysferlinopathy, and sarcoglycanopathy. We are interested in the relationship betwe...

Recent work indicates that free radicals mediate sepsis-induced diaphragmatic dysfunction. These previous experiments have not, however, established the source of the responsible free radical species. In theory, this phenomenon could be explained if one postulates that sepsis elicits an upregulation of contraction-related free radical formation in muscle. The purpose of the present study was to...

We have previously demonstrated that human diaphragm remodeling elicited by severe chronic obstructive pulmonary disease (COPD) is characterized by a fast-to-slow myosin heavy chain isoform transformation. To test the hypothesis that COPD-induced diaphragm remodeling also elicits a fast-to-slow isoform shift in the sarcoendoplasmic reticulum Ca(2+) ATPase (SERCA), the other major ATPase in skel...

In modern microwave systems, a wide variety of frequency-selective devices are used, which performed according to certain technologies. Waveguide filters currently rapidly developing class functional devices. The manufacturing technologies, calculation methods and designs such is great. this paper, we consider band-pass filter on rectangular waveguide with cross section 35×15 mm, in which, inst...

Specially designed ductile end diaphragms of steel bridge superstructures have previously proved, both theoretically and experimentally, to dissipate seismic input energy, protecting other substructure and superstructure members. Although ductile diaphragms have been introduced in the latest AASHTO guide specifications as a structural system that can be used to resist transverse earthquake effe...

This paper discusses the past design practices of flexible diaphragms, the current trend to very large diaphragms, and the new tools available to properly evaluate and engineer these large roof systems. Higher shear demands are accommodated by higher plywood/OSB and steel deck shear capacities accepted by the IBC. A new collective chord technique is presented to more accurately reflect large di...
