The concentrations of Cs and potassium in the surface layers of arable soils were analyzed in the selected region of Eastern Poland approximately 20 years after the Chernobyl power plant accident. Additionally, the occurrence of the elements in soil in the forms available for plants was determined. In relation to the total concentrations of Cs and K in the soil, cesium is found in larger quanti...

Deep water samples collected in 1963 and 1964 in the adjacent seas of Japan were analyzed radiochemically. Sr-90 and Cs-137 were detected in the deep layers down to 6,000 meters deep and showed approximately uniform vertical distributions below 1,000 meters. Mean concentrations of Sr-90 in deep waters were 0.028 ƒÊƒÊc/l in the Pacific and 0.035ƒÊƒÊc /l in the northern Japan Sea, and those of Cs...

In the recently published paper, no direct claims were made since only relatively indirect global ambient radioactivity levels are available [1]. However, available data from reputable sources clearly shows a global annual average population radiation exposure that peaked in 1962 and 1963 shortly after a spike in atomic bomb testing that pre-empted the Partial Test Ban Treaty of 1963 [2]. Ambie...

We present a proof method for intuitionistic logic based on Wallen’s matrix characterization. Our approach combines the connection calculus and the sequent calculus. The search technique is ba...

The microclimate of plant communities varied with energy balance, turbulent exchange and thermal status of the soil surface. Available net radiation is the balance between incoming and outgoing radiation which is the main source of energy in the earth system. The balance of energy at the earth’s surface is closely associated with the overlying atmospheric boundary layer (Roxy et al., 2014). The...

License plate localization for vehicle has been widely studied before, giving favorable results. However, as far as this research has advanced, there is no indication of extensive benchmarks to test the algorithms. Thus, in this work is presented the first stage of a vehicle’s license plate Automatic Recognition System, which is focused to only find the license plate. Three similar algorithms w...

An automated analysis of all reachable states in a distributed system can be used to trace obscure logical errors that would be very hard to find manually. This type of validation is traditionally performed by the symbolic execution of a finite state machine (FSM) model of the system studied. The application of this method to systems of a practical size, though, is complicated by time and space...

We investigate the response of a laboratory aquifer submitted to artificial rainfall, with an emphasis on the early stage of a rain event. In this almost two-dimensional experiment, the infiltrating rainwater forms a groundwater reservoir which exits the aquifer through one side. The resulting outflow resembles a typical stream hydrograph: the water discharge increases rapidly during rainfall a...
