Three new bromotyrosine-derived alkaloids 14-debromo-11-deoxyfistularin-3 (1), aplysinin A (2), and aplysinin B (3), together with 15 known compounds (4-18) were isolated from the sponge Aplysina lacunosa collected from Stirrup Cay, Bahamas. The structures of the isolated compounds were identified on the basis of MS and NMR data analysis. The (13)C NMR assignment of spirocyclohexadienylisoxazol...

To research the deterioration of mechanical properties stirrup-corroded concrete columns under effect load and chloride, accelerated corrosion carrying capacity tests were carried out on subjected to long-term axial loading by means dry wet cycles with extra electric currents. The test results showed that corrosion-induced cracks mainly developed along direction longitudinal reinforcing steel b...

RONALD E. JOHNSON, DPM JAMES R. VEALE, PhD GREG J. McCARTHY, BS The purpose of this study was to compare the ability of four commonly used ankle support devices (Active Ankle, Aircast Sport Stirrup, DonJoy Ankle Ligament Protector and Malleoloc) to restrict active inversion range of motion before and after exercise. The subjects also compared the devices on subjective characteristics including ...

impact of sex pheromones, stirrup-m as additive for acaricides effects were evaluated on panonycjllls lllmi in 1995-1997. peroral (azocyclotin), amitraz (mitac), omite (propargite), neoron (bromopropylate) and citrazon (benzoximate) were tested with and without pheromones and compared with untreated plots with four replications through randomized complete block design. mortality percentage of e...

Stirrup and Underwood make their argument for SPECT imaging from the perspective of ‘‘If it ain’t broke, don’t fix it.’’ They acknowledge the historic value of myocardial perfusion SPECT, as well as the limitations of SPECT technology. Their comments only partially reflect the societal yearning for more precise answers about the presence, extent, and prognosis of patients with coronary artery d...

This numerical study was conducted to simulate and analyze the pushout test for new shear connector in a steel-concrete composite system. In this system, stirrups of reinforced concrete beam are used as connectors when passed through holes drilled web inverted steel T-section. The analysis performed by creating three-dimensional finite element model using program ANSYS 21 student version behavi...
