This paper summarizes the test results of an extensive research program sponsored by the US Transportation Research Board of the National Research Council to examine the behavior of high-strength concrete rectangular columns subjected to concentric and eccentric loading conditions. The variables considered in this investigation were concrete strength ranging from 7.9 ksi (55 MPa) to 16.5 ksi (1...

Mid-substance fibrocartilage develops in bovine deep flexor tendon at the point where the tendon wraps under sesamoid bones of the foot and receives transverse compressive loading during locomotion. Fibrocartilage extends several millimeters into the tendon at this location and the proteoglycan-rich tissue stains intensely with Alcian blue. Using histochemical techniques we demonstrate the pres...

One of the parameters that has been identified as influencing the structural response of buildings is the dynamic Modulus of Elasticity of masonry units. The first aim of this paper is to experimentally investigate the use of high frequency sinusoidal loading to determine the dynamic Modulus of Elasticity of masonry units. The Longitudinal Vibration and the Ultrasonic Pulse methods were origina...

A new test method is developed for studying mixed-mode interfacial failure of thin films using laser generated stress waves. Guided by recent parametric studies of laser-induced tensile spallation, we successfully extend this technique to achieve mixed-mode loading conditions. By allowing an initial longitudinal wave to mode convert at an oblique surface, a high amplitude shear wave is generate...

Harmonic cavities have been used in storage rings to lengthen bunches and increase beam lifetimes dominated by Touschek scattering. Transient beam loading in the harmonic cavities generated by asymmetries in the fill pattern can cause significant variation of the beam phase and bunch length along the bunch train when the longitudinal restoring force has been reduced, resulting in a significant ...

The objective of this study was to assess the prevalence of mucositis and peri-implantitis associated with the use of two types of implants-conventional versus platform switching after one year of loading. A longitudinal study of 64 implants in 25 patients was performed. Clinical variables, such as clinical pocket depth and bleeding upon probing, plaque, mobility, gingival recession, clinical a...

conclusions according to the results of this study, it seems that shift work can be considered a risk factor for high blood pressure changes. it is recommended that workers who are working in shifts are more at risk and need more supervision. background several factors affect the emergence of high blood pressure, among which include environmental and occupational factors. shift work is currentl...

Little direct evidence in man indicates that acute right ventricular loading alters left ventricular configuration. We used the Mueller maneuver (forced inspiration against a closed airway) to increase right ventricular loading and evaluated septal shape and right and left ventricular size in nine normal, semisupine men with phased-array, two-dimensional echocardiography. End-systolic and end-d...

The present longitudinal study was intended to investigate whether the two bilingual experiences of written translation and consecutive interpreting (featured with similar language switching experience but different processing demands) would produce different cognitive control effects in young adults. Three groups of Chinese-English young adult bilinguals, who differed mainly in their half-year...

The existence of long-lived nuclear spin states in four-spin systems is explored by solution-state NMR experiments. Long-lived states are proved to exist in three different natural product molecules, each containing either a AA'BB' or a AA'XX' proton spin system. The measured state lifetimes are between four and eight times the spin-lattice relaxation time constants.
