[en] The pollution of air by dust sulfur dioxide, nitrogen oxides and carbon dioxide emitted from Polish power plants fuelled by coal is discussed and some technical and economical aspects of environment protection are presented. The influence of nuclear power plants and renewable energy sources on the environment is also considered. Some conclusions important for energy policy are given. 39 refs, 21 figs, 17 tabs

[en] The implementation of the Quality Assurance programs in Spain followed the evolution of the applicable codes and standards. At the beginning they were considered as additional requirements to safeguard the safety of the plant. Later on its application revealed its importance as a management tool to obtain better results in the exploitation of the plant. Its implementation required a big effort of the Spanish industry. The start up of the plants together with the reduction of the nuclear program and the diversity of ownership has presented new difficulties to obtain suppliers willing to comply with the Quality Assurance programs requirements

[en] This article shows a wide perspective of the evolution of the Quality concept, paying attention to how Quality is displayed in the nuclear power generation field. It is underlaid that Quality is, nowadays, understood and applied as a management tool. The article also shows a reflection about how a quality management system, the definition of mechanisms that allow to perform such a management system, the methodologies oriented to excellence, and regulations and guides from Regulators and well reputed Organizations, are cornerstones that allow reaching quality in this managerial function.

[en] The sonic molecular arrangers, emitters are of nanofrecuency with some intensity and certain wave lengths that allow you to alter the links existing in the water molecules hydrogen Covalent; What gives these molecules properties more reactive, causing changes in the physical features of water such as viscosity, density, surface tension, capillary action, and thermal permeability.

[en] The most recent developments in Acoustic Emission (AE) for nuclear component monitoring are examined. Suitable AE equipment for logging high rates of AE data, real-time source location and parametric analysis are here discussed. In recent years many AE processes (deformation, slow crack growth, fatigue processes, intergranular stress corrosion cracking, leak monitoring) have been studied and considerable effort has been made in preparing guidelines, recommended practices and standard procedures based on AE. All these aspects are considered and the main results are reported. (author)

[en] This paper reports on use of noble condensed gases as calorimeter media that is attractive due to the possibility to get not only good energy resolution (like in NaI and CsI calorimeters) but better space resolution for photons. Longitudinal segmentation can provide information for particle identification by dE/dx and also e/π-separation based on longitudinal structure of the shower. The best material for this aim is of course liquid Zenon, but it is impossible to get the necessary amount of it in reasonable time. Therefore, the authors have stopped their choice on the next candidate-liquid Krypton (LKr). Its sufficient amount can be obtained before to the beginning of the experiment

[en] Stored resources in trees reflect physiological and environmental variables and affect life history traits, including growth, reproduction, resistance to abiotic stress, and defense. However, less attention has been paid to the fact that stored resources also determine tissue nutritional quality and may have direct consequences for the success of herbivores and pathogens. Here, we investigated whether stored resources differed between two hosts of the mountain pine beetle (Dendroctonus ponderosae Hopkins, 1902): lodgepole pine (Pinus contorta Douglas ex. Loudon), a common host, and whitebark pine (Pinus albicaulis Engelmann), a more naive host that grows at higher altitudes. Phloem and sapwood were sampled in small- and large-diameter trees at two elevations, and nitrogen, phosphorus, nonstructural carbohydrates, and lipids were measured. We found that concentrations of stored resources increased with elevation and tree diameter for both species and that whitebark pine had thicker phloem than lodgepole pine. Overall, stored resources were higher in whitebark pine such that small-diameter whitebark pine trees often had resource concentrations higher than large-diameter lodgepole pines. These results suggest that whitebark pine is of higher nutritional quality than lodgepole pine, which could have implications for the current expansion of mountain pine beetles into higher altitude and latitude forests in response to climate warming.

[en] Flaw evolution monitoring during mechanical fatigue test has been performed by acoustic emission (AE) technique. Testing on 1:5 reduced scale vessel containing fabrication defects was carried out in the frame of an European program for pressure component residual life evaluation. Characteristics of AE signals associated to flaw evolution are discussed

[en] Software for the event geometrical reconstruction and their kinematic analysis being a part of an on-line system for the magnetic spark spectrometer data processing is described. When reconstructing the space picture the distortions of spark chamber glasses are taken into account, as well as track fractures during paritcle rescattering in chambers. Simultaneously kinematic fit and vertex determination which essentially decreases the track angular errors at their extrapolating into vertex is made. Efficiency of automatic processing for three-track events amounts to 92% that for five-track events is 62%. The accuracy over transverse momentum is 17 MeV/c, over the mass of three-pion events - 26-34 MeV/c². A high accuracy of event reconstruction permits to obtain principally new results when studying the pion diffraction on nuclei
