vibration control of multistory buildings by using tupe inversion diviceis
the application of energy absorbing systems in the structures are one of the main methods in attenuation of earthquake effects. in this paper, the vibration control of structures by using of tube inversion systems is considered. in this novel system, the energy is dissipated by the inversion of a metal tube. this energy dissipater has large energy absorbing capacity along with constant stiffnes...
متن کاملEvaluation of California's in-school tobacco use prevention education (TUPE) activities using a nested school-longitudinal design, 2003–2004 and 2005–2006
BACKGROUND Current legislative language requires the California Department of Public Health, California Tobacco Control Program, to evaluate the effectiveness of the school-based Tobacco Use Prevention Education (TUPE) programme in California every 2 years. The objective of the study was to measure change and to identify the impact of school-based tobacco use prevention education activities on ...
متن کاملWater slope and discharge in the Amazon River estimated using the shuttle radar topography mission digital elevation model
[1] We find that the standard deviation, hence error, of the water surface elevation data from the Shuttle Radar Topography Mission (SRTM) is 5.51 m for basin-wide, regional and local Amazon mainstem reaches. This error implies a minimum reach length of 733km in order to calculate a reliable water-surface slope. Resulting slopes are 1.92 ± 0.19 cm/km for Manacapuru, 2.86 ± 0.24 cm/km for Itapeu...
متن کاملeffect of ibbiog io bending and tortitnal resistance of box tupe structures.
in his paper the effect of ribbing in bending and tortional resisance of the box type structure is discussed . for satisfactory design of press structures . the stiffness characteristics of individual components are recognised to be of primary importance. heavy press stucures are normaly constructed in double-sided form . because of transportation and handing problems , these frames are usually...
متن کاملAssociation of the presence of state and district health education policies with school tobacco prevention program practices.
BACKGROUND Texas does not require health education or tobacco use prevention education (TUPE) in its middle schools. During planning for the Texas Tobacco Prevention Initiative, this baseline research was conducted to (1) describe tobacco prevention and control practices in middle schools prior to the pilot, (2) analyze implementation of a state law prohibiting tobacco use on campuses and at sc...
