Fifth Force from Fifth Dimension
Using a novel coordinate system, we rederive the eld equations and equations of motion for 5-dimensional relativity in the general case where the metric can depend on all 5 coordinates (i.e., Kaluza-Klein theory without the cylinder restriction). We show that in general the fth dimension produces a new dynamical force in 4-dimensional spacetime. This timelike fth force is proportional to the 4-...

Removal of heavy metals will allow elimination of toxic substances from environmental samples or will prevent their introduction into the environment. Silica gel will be used to form a complex with other compounds such as nitrilitriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA) and 2mercaptoethanol by an acid catalyzed condensation. Compounds such as NTA were suspended with silica ge...

The Gaia satellite is a high-precision astrometry, photometry and spectroscopic ESA cornerstone mission, currently scheduled for launch in 2012. Its primary science drivers are the composition, formation and evolution of the Galaxy. Gaia will achieve its unprecedented accuracy requirements with detailed calibration and correction for CCD radiation damage and CCD geometric distortion. In this pa...

The observation and measurement of missing transverse energy in an event is a key signature in SUSY searches. This paper describes the reconstruction and calibration of missing transverse energy in ATLAS, and addresses the quality of the measurement in a variety of simulated processes which contain physical missing transverse energy such as Z → τ + τ − , A 0 /H 0 → τ + τ − , t ¯ t, and SUSY as ...

The goals of this paper are to assess feasibility of using total concentration (TPC) of phytoliths in modern soils and morphotypes in soil assemblages to infer paleovegetation cover and composition. We sampled from undisturbed grassland sites with different values of shrub and grass cover in the Columbia Basin, interior Pacific Northwest, USA. Phytolith concentration in soils were measured and ...
