Opis:
The light yield non-proportionality and energy resolution of doped CsI scintillators have been studied for gamma-ray energies ranging from 16.6-1274.5 keV. The light yield non-proportionality of about 20% and the energy resolution of 7.6 š 0.4% for 662 keV gamma-rays have been achieved for empty set 25 mm × 25 mm CsI(Na) crystal, coupled to an XP 5200 photomultiplier tube. The intrinsic resolution of the crystals vs. energy of gamma-rays has been determined after correcting the measured resolution for photomultiplier tube statistics. The different shapes of intrinsic resolution curves observed with various samples of doped CsI are discussed.

Opis:
LaBr3:Ce,CeBr3 and GAGG:Ce scintillators were investigated and the determined characteristics were compared with those obtained for the well-known and widely used CsI:Tl and NaI:Tl crystals. All the detectors were of the same size of 10 × 10 × 5 mm3. The aim of this test study was to single out scintillation detectors most suitable for γ-ray spectrometry and γ -ray emission radial profile measurements in high-temperature plasma experiments. Decay time, energy resolution, non-proportionality and full energy peak detection efficiency were measured for γ -ray energies up to 1770 keV. Due to their good energy resolution, short decay time and high detection efficiency for MeV gamma rays, LaBr3:Ce and CeBr3 scintillators are proposed as the best candidates for use especially under conditions of high count rates, which are expected in the forthcoming DT experiments.

Opis:
To use effectively any radiation detector in high-temperature plasma experiments, it must have a lot of benefits and fulfill a number of requirements. The most important are: a high energy resolution, linearity over a wide range of recorded particle energy, high detection efficiency for these particles, a long lifetime and resistance to harsh conditions existing in plasma experiments and so on. Solid-state nuclear track detectors have been used in our laboratory in plasma experiments for many years, but recently we have made an attempt to use these detectors in spectroscopic measurements performed on some plasma facilities. This paper presents a method that we used to elaborate etched track diameters to evaluate the incident projectile energy magnitude. The method is based on the data obtained from a semiautomatic track scanning system that selects tracks according to two parameters, track diameter and its mean gray level.

Resolution of Civil-Law Disputes by Means of the Administrative Decision of the President of the Energy Regulatory OfficeThe purpose of this article is to present the process of resohdng civil-law disputes by the President of the Energy Regulatory Office by means of an administrative decision under the Energy Law Act. In accordance with the provisions of Article 8(1) of the Energy Law Act, The President of the Energy Regulatory Office is authorised to re-solve disputes referred to in that provision which inherently belong to matters of civil law. Pursuant to Article 2(1) of the Code of Civil Procedurę, civil matters arę heard by common courts of law, except for those delegated to other bodies in special provisions referred to in Article 2(2). An example of such a special provision is Article 8 of the Energy Law Act, which excludes the admissibility of court proceedings in certain disputes to be resolved by the President of the Energy Regulatory Office. Thus, cases of disputes referred to in Article 8 of the Energy Law Act involve on the one hand a strictly civil law dispute and on the other a public authority (central government authority) which is to settle this dispute in a manner appropriate for it using its powers and non-equivalence of entities. Conseąuently, the civil-legal relationship characterised by voluntariness and equivalence of entities is shaped imperatively and unilaterally by a public authority by means of the administrative decision.

Opis:
This paper reports a new multi-item planning and scheduling problem in a job-shop production system with the consideration of energy consumption. A mixed integer linear programming is proposed to integrate planning and scheduling with the consideration of energy aspect. In this study a new operational constraint is considered in the tactical level because of the huge interest given to energy consumption and its strong link existing with production system. To evaluate the performance of this model, computational experiments are presented, and numerical results are given using the software CPLEX and then discussed.

Opis:
The paper discusses the problem of measuring velocity fluctuations of a turbulent boundary layer using single and X-wire probes. It seems that the difference between the streamwise fluctuating component of these two probes results not only from spatial resolution, but also from influence of the wall-normal fluctuating component, which is usually not considered. It was shown that the vector summing these two components obtained from X-wire probe gives the shape of fluctuation distribution obtained from a single-wire probe. It implies that the underestimation of the near-wall peak of streamwise fluctuating component in X-wire measurements results from disregarded wall-normal fluctuations, which is obviously taken in the case of a single-wire probe. Moreover, it was shown that the criteria for wire length i.e. l+ ≤ 20 could not be sufficient to properly estimate the streamwise and wall-normal fluctuations.

Opis:
The increase of maritime international trade, especially of dangerous liquid cargos led to a significant increase of the number of sea-going ships. Their operation poses a real threat to the maritime environment both as a result of terminal events with transported dangerous liquid cargos and emissions of harmful products from fuels burnt by ship power systems. Because of those there is a need to undertake actions to prevent such occurrences using formal, legal and utilitarian tools. Philosophy of research methodology and rationalization of actions in compliance with international directives have been shown. The article presents the guidelines of the IMO Resolution MEPC 231(65) on preventing air pollution with carbon dioxide from ships. Design Energy Efficiency Index (EEDI) for a new ship was given as well as Energy Efficiency Operational Indicator (EEOI) determined for conventional ships after a completed voyage was defined and interpreted. A model of a Ship Energy Efficiency Management Plan (SEEMP) of a chosen ship has been constructed taking into account possible actions aimed at obtaining the highest power efficiency of the ship at sea voyage. Conclusions have been drawn and possible directions of further actions have been established.
