Opis:
The purpose of the article is to present ways to measure inequality. The article describes the last three ways to measure inequality, i.e. based on the Lorenz curve, generalized entropy and the social welfare function. It omits, however, the share and division measures, i.e. the absolute and relative differences, variance, quartile and standard deviations, or positional inequality measures based on percentiles, deciles, quartiles, quantiles, the coefficient of variation and the McLoone index, which results from the fact that although they are often used in empirical research, they illustrate division rather than inequality sensu stricto (i.a. Park 1984, pp. 42-44; Heshmati 2004; Jóźwiak, Podgórski 2012; Jabkowski 2009, pp. 32-35). Thus, the article does not include a wider presentation of these measures.
Celem artykułu jest przedstawienie sposobów pomiaru nierówności. W artykule opisano trzy ostatnie sposoby pomiaru nierówności, tj. w oparciu o krzywą Lorenza, uogólnioną entropię i funkcję dobrobytu. Pomija jednak miary akcji i podziału, tj. różnice bezwzględne i względne, wariancje, odchylenia kwartylowe i standardowe czy też mierniki nierówności pozycji oparte na percentylach, decylach, kwartylach, kwartylach, kwantylach, współczynniku zmienności i indeksie McLoone, co wynika z faktu, że choć są one często wykorzystywane w badaniach empirycznych, to jednak ilustrują raczej podział, a nie zmysłową nierówność sensu stricto (i.a. Park 1984, s. 42-44; Heshmati 2004; Jóźwiak, Podgórski 2012; Jabkowski 2009, s. 32-35). W związku z tym artykuł nie zawiera szerszej prezentacji tych środków.

Opis:
The paper compares the requirements for vibration-based condition monitoring system for two seemingly similar rotary machines, namely horizontal and vertical-axis wind turbines. The paper shows that the differences in the design have a significant influence on both, operational parameters and wind energy conversion, and what are the consequences from condition monitoring point-of-view. In addition, the authors present a list of obstacles during worldwide development of vibration-based guidelines, which has led to major constraints within practical data acquisition and processing. Finally, the paper presents comparison of experimental data and complete schemes of mechanical components of drive trains of both types of turbines.
W artykule porównano wymagania dla systemu monitorowania dwóch pozornie podobnych maszyn wirnikowych, mianowicie turbin wiatrowych o poziomej i pionowej osi obrotu wału głównego. Autorzy pokazali analizę, z której wynika, że różnice w konstrukcji mają znaczący wpływ zarówno na parametry eksploatacyjne, jak i na konwersję energii wiatrowej oraz jakie są konsekwencje tych różnic z punktu widzenia oceny stanu technicznego. Ponadto, autorzy przedstawili listę powodów, które sprawiły, że do dnia dzisiejszego, światowym organizacjom udało się opracować się jedynie normy odnoszące się do analizy niektórych typów maszyn w wąskim przedziale warunków operacyjnych. Na koniec przedstawiono porównanie danych eksperymentalnych i schematów mechanicznych elementów układów napędowych obu typów turbin.

Opis:
Since 2008, it has been recognised by most health authorities worldwide that the abuse of newly-emerging psychoactive drugs, (‘designer drugs’/‘legal highs’; DD), in youth is a rapidly increasing problem, especially in the EU, threatening to offset gains made in tackling established and illegal drugs which they are intended to mimic; DD diversity is continually increasing to circumvent laws. The aim of the study was to determine the scale of DD abuse/availability amongst Polish youth. The surveyed test population was randomly selected from a representative group of adolescents attending high schools, secondary schools and universities throughout Poland. Questionnaires were completed by 14,511 subjects (10,083 school pupils and 4,428 students). Few persons from each group admitted using DDs; 453 schoolpupils (4.49%) vs. 81 students (1.83%). More males (4.74%) took DDs than females (2.77%). The tendency to take DDs in the company of friends was high in both DD-taking groups (>80%). DDs were consumed mostly in open spaces (34.15%), discos/pubs (21.13%) and boarding school/friend’s house (20.57). Most frequently, DDs came from shops (57.68%), friends (31.46%) or dealers (10.11%). Ensuing symptoms included; happy/euphoric mood (58.80%), talkativeness (42.51%) and hallucinations (22.85%). Over 74% of DDtakers in both groups experienced adverse reactions, and those requiring help sought it from: friends/colleagues (6.74%), doctors (5.06%), and hospitals (4.87%), but most rarely from parents/guardians (2.62%). Urgent action is being taken, especially in youth education, to prevent DDs becoming the serious menace seen with conventional drugs.

Opis:
The horse chestnut leaf miner, Cameraria ohridella Deschka & Dimic (Lepidoptera: Gracillariidae), is a new invasive pest that has spread all over the Europe over the last 25 years. This paper presents research aimed to: 1) compare the effectiveness of sticky pheromone traps of various types (sizes and colors), 2) determine the effect of a trap location on moth catches. Studies were conducted in Warsaw and Falenty near Warsaw. No trap color preference by male moths was found in tests of white, blue and green barrier traps. Barrier traps had the largest sticky area (32 dm2) in comparison to PL-2 (5.625 dm2) and delta PL-1 (3.4 dm2) traps, thus they caught the highest total number of males, however PL-2 traps were the most effective (268-381 moths/dm2). The results of the studies suggest that to make traps with the C. ohridella pheromone be more effective they should: a) be located on a stem below a tree crown or in its lower part for the first C. ohridella generation, and in crowns for the second and later insect generations, b) be placed in some distance from a tree stem, if located in crowns.

Opis:
The inelastic mean free path of electrons (IMFP) is an important material parameter for description of electron transport processes in solids. This parameter is particularly useful for quantifying the electron spectroscopies, in particular Auger electron spectroscopy, X-ray photoelectron spectroscopy, electron energy loss spectroscopy and elastic peak electron spectroscopy. In this work, a brief overview of the IMFP determination is presented. Generally, there are two groups of methods to determine the IMFP: (i) calculations using the theoretical model based on the experimental optical data, and (ii) calculations using theory relating the IMFP and the measured probability elastic electron backscattering from solids. Major advances in the development of the second group of methods were made in three laboratories; these advances are reviewed here. The elastic backscattering probability, in absolute or relative units, can be conveniently evaluated from the elastic peak intensity. However, much effort is needed to develop the theory for calculating the IMFP, which typically involves the Monte Carlo simulations of electron trajectories in solids. Presently, this theory and typical procedures of the spectra processing are implemented in the software package EPESWIN developed by Jablonski. In recent years, much attention is devoted to the phenomenon of the electron energy losses in the surface region of solids. Reliability of the theory of elastic backscattering is distinctly improved if this effect is taken into account.

The paper presents the results of hardness tests of aluminum alloy AW-7075 (for plastic processing) and Ni-P chemical coatings (nickel-phosphorus) which had been applied by the no-current method. Coatings of various thickness have been made and their influence on the increase of the top layer hardness has been determined, as well as the increase of the hardness of the coating and substrate system after puncturing the coating with an indenter. The purpose of the investigation was to determine the possibility of applying the Ni-P coating for selected technical applications, among others, by the selection of its optimum thickness on the hard aluminum alloy and by the determination of the deformation resistance of the top layer if the given coating.

Introduction and objective. As landowners occupied with agricultural production comprise a sizeable part of the populations in mid- and western European countries, it seemed reasonable to assess the organization of health care systems concerning farmers and their families in Poland and Germany. Both countries have similar geographical conditions and rural environments. It so happens that in Poland the principles of the system of agricultural insurance (KRUS) is based on the experiences of Germany and France. State of knowledge. Basically, both in Poland and Germany, the agricultural health insurance companies provide the same insurance cover as other health insurance companies. In both countries, under certain conditions, in the case of illness, the insured farmers receive instead of sickness benefit operational assistance and home help. In spite of the similarities that characterize both administrations, many particular differences are to be noted, e.g. the farmers’ social insurance in Poland is subject to only one ministry, in contrast to Germany where two ministries are responsible for farmers’ social insurance. In Poland, KRUS is a monopolistic organization, whereas in Germany, nine similar independent structures fulfil the task of a health insurance company. Needless to say, many more funds are available for prevention, treatment and rehabilitation in Germany than in Poland, due to obvious differences in the overall national income.

Opis:
In this contribution we have studied magnetisation of Mg/Ni multilayers (MLs) to characterise the alloing effect near interfaces. The layered structure was characterised by standard X-ray diffraction. The MLs were deposited by UHV magnetron sputtering onto naturally oxidised Si(100) substrates. Results showed, that due to Mg-Ni alloy formation near interfaces the magnetizations of the MLs were strongly reduced. Effective "dead" Ni layer thickness was estimated as 1.2 nm at room temperature (RT). Furthermore, hydrogen absorption kinetics at a pressure of about 1000 mbar was studied at RT in Pd covered Mg/Ni MLs using four-point resistivity measurements. Results showed that the fastest initial rise in resistance in the first 9 s was observed for d_{Ni}=3.5 nm.

Free Electron Laser in Hamburg (FLASH) and X-Ray Free Electron Laser (XFEL) are linear accelerators that require a complex and accurate Low Level Radio Frequency (LLRF) control system. Currently working systems are based on aged Versa Module Eurocard (VME) architecture. One of the alternatives for the VME bus is the Advanced Telecommunications and Computing Architecture (ATCA) standard. The ATCA based LLRF controller mainly consists of a few ATCA carrier boards and several Advanced Mezzanine Cards (AMC). AMC modules are available in variety of functions such as: ADC, DAC, data storage, data links and even CPU cards. This paper focuses on the software that allows user to collect and plot the data from commercially available TAMC900 board.

Opis:
Oxidation process of Fe films under atmospheric conditions is depth limited such that an oxide covering layer with a well-defined thickness is formed by which the underlying metal is prevented from further oxidation. Iron thin film with an initial thickness d_{i}=4 nm was deposited onto 1.6 nm - V(110) buffer layer using UHV magnetron sputtering. The planar growth of Fe oxides was revealed by atomic force microscopy. X-ray photoelectron spectroscopy studies performed after 250 days of oxidation revealed formation of a hematite (α-Fe₂O₃) ultrathin film on the metallic rest of iron. Furthermore, low temperature magnetic measurements of the oxidised Fe ultrathin film revealed an exchange anisotropy which is imposed to the metallic rest. As a result, we have observed at low temperatures a shift and broadening of the hysteresis loops due to the exchange interaction at the metal-oxide interface.

Opis:
Future RF Control systems will require simultaneous data acquisition of up to 100 fast ADC channels at sampling rates of around 100 MHz and real time signal processing within a few hundred nanoseconds. At the same time the standardization of Low-Level RF systems are common objectives for all laboratories for cost reduction, performance optimization and machine reliability. Also desirable are modularity and scalability of the design as well as compatibility with accelerator instrumentation needs including the control system. All these requirements can be fulfilled with the new telecommunication standard ATCA when adopted to the domain of instrumentation. We describe the architecture and design of an ATCA based LLRF system for the European XFEL. Initial results of the demonstration of such a system at the FLASH user facility will be presented. Presented are the results of operating essential components of a prototype during the machine studies in January and March 2009.
