Opis:
Breakfast cereal is a regular component of daily diets in Poland and in other countries. Since these products are very popular components of diets, they should be a source of key nutrients, including minerals. The objective of the study was: 1) to determine how popular cereals were among young and preteen school children; 2) to verify whether cereals could be a source of sodium (Na), potassium (K), calcium (Ca) and magnesium (Mg). 232 ready-to-eat products were tested. The content of Na, K, Ca and Mg was determined using flame atomic absorption spectrometry in a Varian SpectrAA 280 FS. Daily intake of Na, K, Ca and Mg by children (aged 7 - 12 years) from 1 serving of breakfast cereals (1 serving size = 30g cereal + 125 ml milk) was compared with AI (for Na and K) or RDA (for Ca and Mg). The highest content of Na was recorded in cornflakes (approx. 500 mg/100 g), K in bran (more than 250 mg/100 g), Ca in bran and wholegrain cereals (approx. 57 mg/100 g), Mg in bran (nearly 180 mg/100 g). It was found that although cereals were not a rich source of Na, K, Ca and Mg for the studied group of consumers, when prepared with milk their nutritional value was significantly enhanced. One serving of breakfast cereals with milk per day would cover 5 – 17% of AI for Na, 5 - 7% of AI for K , 12 – 17% of RDA for Ca and 10 – 57% of RDA for Mg. Cornflakes, which turned out to be the richest source of Na, were the least valuable in terms of the content of the macroelements, in which they resembled rice flakes. All breakfast cereals, while not being particularly rich in Na, K, Ca and Mg, when prepared with milk have a considerably better value for school-age children and ensure a higher consumption of milk.

Opis:
The aim of this article is to present selected methodological threads of the discussion on the status of historical sources which took place in Polish post‑war historiography. In the article, I present the concepts of the historical source formulated in 1957–1989, mainly by Gerard Labuda and Jerzy Topolski. Further in the text, I will present the discussion about Topolski’s concepts and characterize the peculiarities of contemporary history as regards historical sources. In the light of the presented classification of sources, I will reflect on the status of the documents created by the apparatus of repression of the Polish People’s Republic.

Opis:
The future accelerators need ion beams with higher charge state and higher current. This demand will be met by the “third generation Electron Cyclotron Resonance Ion Sources” (ECRIS) which will make use of improved plasma confinement by means of higher magnetic field and of higher microwave frequency, thus boosting the performance of nowadays ECRIS operating at the frequency of 14 and 18 GHz. The possibility to obtain confining fields exceeding 4 tesla, by means of special design of NbTi superconducting magnets, open the way to a new operational domain, at the typical frequencies of gyrotrons, above 28 GHz, with plasma densities never achieved before in ECRIS (1013 cm–3 and higher). The test of SERSE at 28 GHz, confirming the theoretical frame on which the third generation ECR sources design is based, will be presented; a synthetic review of the new generation ECRIS is carried out, with a particular emphasis on the design of the GyroSERSE source. Finally, the scheme of an innovative hybrid source will be outlined and a short description of the ECLISSE (Electron Cyclotron Resonance ion source Coupled to a Laser Ion Source for charge State Enhancement) experiment is hereinafter presented.

Opis:
The Sukorejo Village is a mangrove ecotourism place on the coast of Gresik City and is also located in the Industrial Estate. The carbon dioxide (CO2) emissions from industrial and residential activities in the Sukorejo Village affect the air quality in Gresik City. This study calculated the CO2 emissions from industrial and residential sources in Sukorejo Village, Gresik. In addition, it also estimated the ability of green open spaces in the Sukorejo Village to absorb the CO2 emissions. Calculation of the CO2 emissions from industrial sources requires the data on fuel and electricity consumption, while from residential sources requires the data on population, LPG and electricity consumption. Calculation of the CO2 emission absorption was based on the area of green open space in the Sukorejo Village, Gresik. The results of the study show that the CO2 emissions from industrial sources are 20,224.15 tons/year, while from residential sources are 2,164.63 tons/year. Green open space in the Sukorejo Village which consists of mangrove trees and shrubs is able to absorb the CO2 emissions of 129.19 tons/year. These results indicate that the vegetation in the green space is still not able to absorb the total CO2 emissions from industrial and residential sources. Therefore, it is necessary to add vegetation or private green open space to absorb all the CO2 emissions from industrial and residential sources. There are several scenarios of adding vegetation. Scenarios 1 to 4 require the addition of 1 type of plant that has a high absorption capacity of the CO2 emissions. In turn, scenario 5 requires the addition of several types of plants.

We present a highly efficient filter structure to create power-complementary filter pairs for phantom source widening. It either introduces frequency-dependent phase or amplitude differences in a pair of loudspeaker signals. We evaluate how the perceptual effect is influenced by off-center listening positions in a standard ±30o loudspeaker setup. The evaluation of the phantom source widening effect is based on measurements of the inter-aural cross-correlation coefficient (IACC), which is justified by its pronounced correlation to the perceived phantom source width in prior listening test results.

Opis:
This paper aims to present and discuss the already existing studies and try to uncover possible potential for further research on the topic of financial resources in public–private partnership (PPP) projects. The article presents the main relevant papers regarding financial resources and examines how deep the topic of financial sources has been explored in both academic and practical literature. Moreover, the article reviews Poland’s PPP market and, particularly, types of used financial sources. The ‘Literature review’ results show that there is a gap in studying the private sector and financial resources, especially in Polish PPPs. We attempt to close this gap by summarising the main factors that influence the choice of the source of financing PPPs. The Polish case shows that the main source of financing of PPP projects in Poland is bank loans and many projects have partial funding from various European Union (EU) programmes. Policymakers should pay attention to other financial resources in PPPs. Moreover, it would be fruitful to extend the Polish database of PPP projects with new factors that can simplify ex-post and ex-ante analysis.

Opis:
Current source inverters (CSI) is one of the widely used converter topology in medium voltage drive applications due to its simplicity, motor friendly waveforms and reliable short circuit protection. The current source inverters are usually fed by controlled current source rectifiers (CSR) with a large inductor to provide a constant supply current. A generalized control applicable for both CSI and CSR and their extension namely current source multilevel inverters (CSMLI) are dealt in this paper. As space vector pulse width modulation (SVPWM) features the advantages of flexible control, faster dynamic response, better DC utilization and easy digital implementation it is considered for this work. This paper generalizes SVPWM that could be applied for CSI, CSR and CSMLI. The intense computation involved in framing a generalized space vector control are discussed in detail. The algorithm includes determination of band, region, subregions and vectors. The algorithm is validated by simulation using MATLAB /SIMULINK for CSR 5, 7, 13 level CSMLI and for CSR fed CSI.

Opis:
In this paper, a new formulation based on the method of fundamental solutions for two/three- -dimensional steady-state heat conduction problems involving internal curved line/surface heat sources is presented. Arbitrary shapes and non-uniform intensities of the curved heat sources can be modeled by an assemblage of several parts with quadratic variations. The presented mesh-free modeling does not require any internal points as in domain methods. Four numerical examples are studied to verify the validity and efficiency of the proposed method. Our analyses have shown that the presented mesh-free formulation is very efficient in comparison with conventional boundary or domain solution techniques.

Opis:
The geochemical characteristics of the Palaeozoic and Mesozoic strata of the basement of the Carpathian Foredeep depicted the Devonian and Carboniferous source rocks as the best source for hydrocarbon generation. Moreover, the Outer Carpathian sequence was geochemically characterized and proved capable of generating hydrocarbons. The oil-source rocks’ correlations indicated that the source of the condensate accumulated in the Łąkta field, while oil in the Grobla field. Maturity modelling identified Devonian source rocks as they reached a late phase of the “oil window” and, locally, even the “gas window”. The Carboniferous source rock was mature enough to start the generation processes. The generation started in the late Carboniferous, both in the Upper Silesian and Małopolska blocks. The main phase of the petroleum processes took place in late Neogene. The expulsion was observed only in the Devonian source rocks, and vertical migration by fault system in both blocks resulted in oil and gas accumulation in the Upper Jurassic carbonates and Upper Cretaceous sandstones. The petroleum modelling indicated the Devonian source for oil and gas fields in the study area. However oil-source rock correlation also suggests the presence of the Carpathian flysch source for hydrocarbons accumulated in the Łąkta field.

Opis:
The paper includes the issues related to sustainable development in the energy-using sectors in the European Union countries. The paper presents the analysis of participation of renewable energy in the total energy consumption in these sectors of the European economy. It was found that participation of renewable energy in the total energy balance continues to increase, differs in each country and is not dependent on the macroeconomic situation. Strong positive correlation between participation of renewable energy and afforestation rate was found, which is caused by largely involvement of biomass in renewable energy. The research indicates that the economic aspect for sustainable energy development is of low importance, the ethical field and the need to preserve resources for future generations are crucial.
Przedstawiono zagadnienia związane z rozwojem zrównoważonym w sektorach wykorzystujących energię na przykładzie krajów UE . Dokonano analizy udziału energii odnawialnej w zużyciu całkowitym energii. Stwierdzono, że udział energii odnawialnej w bilansie całkowitym energii ciągle wzrasta, jest zróżnicowany w poszczególnych krajach oraz nie zależy od sytuacji makroekonomicznej. Stwierdzono silną dodatnią korelację między udziałem energii odnawialnej a lesistością, co było spowodowane dużym wykorzystaniem biomasy w energetyce odnawialnej. Przeprowadzone badania wskazują, że aspekt ekonomiczny w przypadku zrównoważonego rozwoju w sektorach wykorzystujących energię miał małe znaczenie, a na pierwszy plan wysuwały się płaszczyzna etyczna i konieczność zachowania zasobów dla przyszłych pokoleń.
