[en] In most laboratory studies with oral exposure of terrestrial invertebrates to metals an artificial food, which is easy to handle, is used. The bioavailability of metals from this artificial food may, however, be much higher than from more field relevant food sources. Such differences may affect toxicokinetic processes in different tissues. To test the effect of bioavailability of Cd in food on Cd toxicokinetics and internal distribution in terrestrial invertebrates, we performed the experiment using the ground beetle Pterostichus oblongopunctatus exposed to Cd via food differing in their soluble Cd pool. We showed that in carabids Cd accumulation and elimination pattern in different tissues is not governed by the metal availability in food.

[en] The BT-S4 unit consists of a support suspended from the ceiling on which the X-radiator is fixed, a Bucky table with floating plate, and an integrated device for tomographic movements in two dimensions. The blowing device is driven by two motors in the suspended support. Coupling between focus and detector path is assured by a rod, which can be decoupled, the fulcrum being stationary. The layer is selected by adjusting the distance from table to detector. Both for radiographic and tomographic purposes the device can be furnished with a system function, jointly with the generator, for automatic exposure. (orig./HP)

[en] This paper presents alternative solutions to ensure power supply of critical consumer, such hospitals. In a hospital it is extremely important to have a power supply without any interruption. This is the reason of the using various solutions that ensure continuity of power supply. In this paper it is presented a solution used in a hospital in Romania. Here is used a generator controlled by microprocessor capable of taking over power supply in case there are problems with power supply from the national power grid. (paper)

[en] Together with wave energy, ocean thermal energy, and the often overlooked energy from ocean curents tidal energy belongs to those renewable energy sources that can be subsumed under the generic term of ocean energy. All that these energy sources have in common, however, is that they are found in the ocean. The present article discusses tidal energy with respect to the four principal factors determining the scope of a renewable energy source, namely global, technical, and economic availability and ecological acceptability.

[en] Highlights: • In this article we propose a method of phase definitions of the various forms of ³H in the soil. • Detailed consideration of the alleged speciation of ³H in the soil. • We investigated the distribution of speciation of ³H and in the soils of radiation-dangerous objects. • Revealed that the distribution of speciation form of ³H associated with the mechanism of formation of ³H in the study object. - Abstract: Speciation of tritium (³H) in soils from the “Balapan” site in Semipalatinsk are presented in this study. Three interrelated objects were chosen for further study: “Atomic” lake, the Shagan River and an external reservoir. The main speciation forms of ³H in soil were: ³H in surface-adsorbed water, ³H in interlayer water, hydroxylic ³H, organically bound ³H and crystalline-bound ³H. Results will allow an estimation of contamination mechanism to be made, and will also allow the potential for migration and bioavailability of ³Hto be assessed.

[en] Highlights: • Responses of upstream stock returns to world non-US oil supply shock increase over time. • Responses of upstream stock returns to US oil supply shock are positive and persistent. • Effects of oil supply shocks are asymmetric for independents and integrated firms. • A structural change in the causal relationship between oil market and stock return - Abstract: A time-varying parameter VAR model is used to examine the impact of structural oil supply shocks on the US real stock market return of oil and gas exploration and production companies. The result shows that the impact response of the real return of the upstream stocks to a negative world non-US oil supply shock increases substantially over recent years, from an average value of 0.70% in 2006 to 6.16% during 2008–2010, with a spike of 6.81% in 2014Q3. The endogenous effects of US oil supply shocks on the return play an important role, in that the responses of the stock returns to a negative US oil supply shock are positive and persistent with an average value of 3.60% over time. The time-varying effects of oil supply shocks are heterogeneous. The magnitudes of return responses are different among independents, large proved-reserve independents and integrated companies over time.

[en] Allocation of inspection resources for international safeguards is considered as the problem of designing a complex system that is composed of individual inspection activities and that has the objective of detecting material loss. Optimization theory is applied in selecting those inspection activities that maximize a system performance measure within resource constraints. The method is applicable to a global allocation problem in which inspection resources are distributed throughout a hierarchy consisting of multiple countries, multiple facilities within each country, and multiple activities within each facility. 9 references
