Reports of radiation from granite counter tops generated public interest in the potential exposures to external gamma radiation and internal exposure from radon decay products created by building materials. The gamma radiation, radionuclide content and surface dose rates were measured in 322 slabs of 254 named stone types (area ~50 ft per slab) and 14 smaller samples (area ~1 ft). Average surfa...

There has been recent speculation and controversy regarding whether electromagnetic zero-point radiation might be the next candidate in the progression of plentiful energy sources, ranging, for example, from hydrodynamic, chemical, and nuclear energy sources. Certainly, however, extracting energy from the vacuum seems counter intuitive to most people. Here, these ideas are clarified, drawing on...

Some of the developments related to quantum anomalies and path integrals during the past 10 years are briefly discussed. The covered subjects include the issues related to the local counter term in the context of 2-dimensional path integral bosonization and the treatment of chiral anomaly and index theorem on the lattice. We also briefly comment on a recent analysis of the connection between th...

A new instrument for direct measurements of heavy cosmic ray nuclei (oxygen to iron) in the energy range from about 10 to several 10 eV is described. The detector consists of a counter telescope with a proportional tube array and a transition radiation detector. Single wire proportional tubes are used which allow operation in the low pressure environment of stratospheric balloons without requir...

This paper describes a new measure for presence in immersive virtual environments (VEs) based on data that can be obtained unobtrusively during the course of a VE experience. At different times during an experience a participant will occasionally switch between interpreting the totality of sensory inputs as forming the VE or the real world. The number of transitions from virtual to real is coun...

We present results on dijet and W+dijet production at hadron colliders obtained by supplementing the leading log BFKL resummation with energy and momentum conservation. For pure dijet production, the inclusion of the BFKL radiation in the energy conservation leads to a decrease in the parton flux sufficient to counter-act the expected exponential increase in the cross section obtained for the p...

Background: The annual effective dose equivalent (AEDE) due to ionizing radiation in a coaster area in Nigerian has been determined using Geiger-Muller counter. Materials and Methods: isolevels in the study area were represented by using the kriging interpolation technique on ArcGIS 10.1 software. Duncan multiple range test was performed using Statistical Package for Social Sciences (SPSS). Res...

To selectively remove mercury(II), 2-hydroxyethyl methacrylate (HM) and methacrylate/acrylamide (HM/ACR) hydrogels were synthesized using radiation. These used in swelling, diffusion, binding studies. Swelling parameters for HM/ACR−Hg2+ system are higher than those of HM−Hg2+ systems. Binding Hg2+ has been observed to be C-type HM L-type HM/ACR hydrogels. calculated Freundlich, Langmuir Henry m...
