A bimonthly coral-based record of the postbomb radiocarbon content of Solomon Sea surface waters is interpreted to reflect mixing of subtropical surface water and that advected in from the east by the equatorial branch of the South Equatorial Current (SEC). Annual mean D14C has a dynamic range of nearly 175‰, with a total range of nearly 200‰. Prebomb values average 256‰ and the annual mean pos...

Rejection thresholds of eight primary alcohols applied to the tarsal chemoreceptors of the blowfly Phormia regina Meigen and the ovipositor of Gryllus assimilis Fab. have been determined. Three different solvents for the alcohols have been used: water, ethylene glycol, and mineral oil. The comparative stimulating effectiveness of the alcohols assumes a different aspect with each different solve...

The US Public Health Service has finalized its recommendation relating to community water fluoridation (Federal Panel on Community Water Fluoridation, US Department of Health and Human Services, 2015). It recommends an optimal concentration of 0.7 mg/l F based on their argument that this concentration provides the best balance of protection from dental caries while limiting the risk of dental f...

(1) Efflux CUN~S of 3HH0 from intact isolated muscle fiber of the giant barnacle were studied by a continuous washout technique. (2) The accuracy of the washout technique was analyzed by studying the efflu of ‘HHO from two models: a) microsacs of collodion and, b) cylinders of agar gel. In both cases the experimental efflux kinetics follow the predictions of the respective models: surface-limit...

Positron range is one of the main physical effects limiting the spatial resolution of positron emission tomography (PET) images. If positrons travel inside a magnetic field, for instance inside a nuclear magnetic resonance (MR) tomograph, the mean range will be smaller but still significant. In this investigation we examined a method to correct for the positron range effect in iterative image r...

Under suitable assumptions we prove that there does not exist a perfect exact multiple test procedure would apply simultaneously to any positive correlation coefficient even with known distribution of statistics. This nonexistence theorem holds for all simple tests under normal distribution, and Ferguson’s distribution. Given the test, provide least conservative using three parametric models. T...

the usage of turbochargers in diesel engines has led to the downsizing of the motors as well as usage of the waste gates in turbochargers. any dimensional reduction in turbochargers and appurtenant leads to an enhancement on the performance of internal combustion engines and in environmental problems in terms of aerodynamic, thermodynamic and mechanical specifications for both engines and turbo...

Regulation of the flow and movement of water is essential to the health and well-being of our bodies. Involving a diverse array of structures that range from molecular gatekeepers to tissue barriers, water flow and concentration are maintained at precise levels. However, in many instances we do not have a complete picture of how this works. A case in point is the arterial wall, which separates ...
