in this paper are present the results of measurements of magnetic induction at some locationsin city bor (the east serbia) dating from the household electric devices and transformer stations suited near the residental areas. stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. risk of the extremely low fr...

background : exposure to formaldehyde (fa) causes irritative effects and induces nasopharyngeal cancer; the interna­tional agency for research on cancer (iarc, lyon) classified fa as carcinogenic to humans, group 1. many studies have been published so far concerning the occupational exposure of industrial workers, embalmers, pathologists and anatomists to fa but very few data regarding medical ...

failure of the quay walls due to earthquakes results in severe economic loss. because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. this study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

The increasingly uncertain business environment requires the necessity to implement more flexibility in companies. Unfortunately, companies being specialized in engineer-to-order production cannot use safety stocks which are generally used in make-to-stock productions to secure flexibility. Therefore, an alternative approach has to be developed to facilitate procurement flexibility for these co...

• We study the impact on road safety of announced one-day speed limit monitoring operations (SLMO). SLMO are accompanied by media campaigns that provide information dangers speeding. find reduce traffic accidents and casualties about eight percent. Immediately after end, return to usual level. Drivers react an increased detection probability violations. Providing speeding does not alter speeder...

Answer set programs with external source access may introduce new constants that are not present in the program, which is known as value invention. As naive value invention leads to programs with infinite grounding and answer sets, syntactic safety criteria are imposed on programs. However, traditional criteria are in many cases unnecessarily strong and limit expressiveness. We present liberal ...
