Introduction: Public and occupational exposure to extremely low frequency (ELF) electric and magnetic fields induced by electrical equipment is a significant issue in the environment and at the workplace due to their potential health effects on public health. The purpose of this study was assessment of the electric and magnetic fields intensities and determination of mental and psychological ef...

The case histories of two individuals exposed to thermal radiation emitted from an electric oven and range were presented. In one patient, earlier exposure to medical diathermy appears to have initiated delayed or late-appearing, capsular cataracts. Instead of the anticipated slow progression, the cataractogenesis was accelerated following recent, repeated exposure to the intense, infrared radi...

Spatially separated electron donors and acceptors in sediment can be exploited by the so-called “cable bacteria.” Electric potential microelectrodes (EPMs) were constructed to measure the electric fields that should appear when cable bacteria conduct electrons over centimeter distances. The EPMs were needle-shaped, shielded Ag/AgCl half-cells that were rendered insensitive to redox-active speci...

Energy efficiency potential studies are being used by policymakers to inform decisions from approval of utility rate cases to developing legislation requiring energy efficiency supply some percentage of future consumption (in most cases, the ‘‘energy’’ is limited to ‘‘electricity generating sources’’). T his article seeks to provide a preliminary discussion of commonalities and differences in e...

The paper deals with exploiting the potential of interaction histories for managing multiple project contexts in both traditional and smart environments. Mapping interaction histories to specific projects is proposed as a way to make interaction histories a useful resource for supporting continuous, coordinated work on a set of projects over time and distributing resources across contexts and d...

Gradients of many kinds have been described in a variety of living organisms, including invertebrates as well as vertebrates. The extensive studies of Child and his co-workers have shown rather wide differences in physiological activity between apical and basal poles in certain invertebrates and between head and tail in longitudinally organized animals. The rates of 02 consumption and CO2 forma...

The predictions of the Bohmian and the decoherent (or consistent) histories formulations of the quantum mechanics of a closed system are compared for histories — sequences of alternatives at a series of times. For certain kinds of histories, Bohmian mechanics and decoherent histories may both be formulated in the same mathematical framework within which they can be compared. In that framework, ...

The electric catfishes of African rivers and lakes, once depicted on Egyptian tomb art, have been largely overlooked in histories and reviews of electric fish biology and animal electricity. This article examines how Westerners, especially Dominican and Jesuit missionaries, discovered them in Ethiopia and other parts of Africa at the beginning of the seventeenth century. What transpired took pl...

Inverse problems and inverse analyses, which deal with estimation of inputs or source from outputs or results, have been receiving increasing attention in various fields of science and engineering. A reasonable classification of the inverse problems is described. The nature of inverse problems and difficulties encountered in the inverse analyses are discussed. Typical inversion analysis schemes...
