High tall buildings are more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) were studied. TMD was proposed to study response of 20 storey height building to seismic excitations using time history analysis with and without the TMD. The study indicates that the response of structur...

INTRODUCTION The study aimed at determination of the usefulness of the subjective assessment of selected signs of fungi growth in flats and microclimate parameters to indicate the actual air contamination with culturable fungi, (1→3)-β-D-glucans and fungal spores. MATERIAL AND METHODS This analysis covered 22 flats, the inhabitants of which declared in a questionnaire interview the presence o...

The efficacy of a photostable formulation of methoprene and two photostable juvenoids, fenoxycarb and pyriproxyfen, and their residual activity in inhibiting the emergence of adult cat fleas, Ctenocephalides felis (Bouché), was studied in topsoil. Nursery pots composed of clay, peat, and plastic, and wooden flats were used to hold soil samples. Treated soil samples were exposed to sunlight duri...

15 16 Tidal Flats are important examples of extensive areas of natural environment that remain 17 relatively unaffected by man. Monitoring of tidal flats is required for a variety of 18 purposes. Remote sensing has become an established technique for the measurement of 19 topography over tidal flats. A further requirement is to measure topographic changes in 20 order to measure sediment budgets...

Five dose reconstruction projects focusing on historical public exposures from U.S. government nuclear facilities have been completed in the last 12 y (Fernald, Hanford, Nevada Test Site, Oak Ridge, Rocky Flats). Using information available in published reports, doses and excess health risks of the most serious contaminants in each study are compared for representative maximally and typically e...

What is the subject here? The aim is to gain control of this medium, mostly so as to be able to make those faces, my main proving ground. And the medium itself —is what? Clearly it involves folding curves (in, as it happens, rectangles of brown wrapping paper sprayglued to thick aluminum foil). Now curve-folding, as is known, creates surfaces that won’t lie flush to each other, or “open folds”;...

We examine the noise contributed by the WFPC2 flatfields during normal calibration, and provide new low-noise flats for 41 filters. Highly exposed science images (>20,000 electrons per pixel) will show significant noise reduction if these new flats are used; this is especially true for images on the PC1 chip. For some ultraviolet filters a significant improvement occurs even for much lower expo...

The objectives of our studies in FY09 are to collect observations of currents, waves, and bathymetry on tidal flats, and to develop, test, and improve models for tidal-flat processes and for mud-induced dissipation of waves in shallow water. Specific goals relating to tidal flats are to: Investigate the relative importance to the circulation of riverine and tidal flows, and Estimate the bottom ...

The public health movement has been concerned with the relation between housing and health for well over a century. Nevertheless the Black Report still identified housing as one of the major causes of ill-health and suggested, on one indicator at least, that council housing is the least healthy form of tenure. An exploratory study concerning housing and health in a north eastern local authority...
