Weak verbs in Modern English are sometimes mistakenly identifi ed with regular verbs. Although most weak verbs are indeed regular, there remain some which belong to the irregular group, for example spend, put, make, burn. Apart from drawing a clearer distinction between strong and weak verbs in relation to the regular and irregular division, the aim of this paper is to explain where the irregularity of these irregular weak verbs comes from and to gather possible relicts still present in Modern English. The paper discusses 56 such irregular weak verbs without vowel alternations and 9 archaisms preserving traces of such infl ection. The 56 irregular weak verbs are divided into groups according to the patterns they display and they are additionally marked depend-ing on whether: (1) they have less common irregular preterite and past participle forms, which can be labelled as “literary”or“poetic,” (2) they are literary themselves, (3) they have irregular preterite and past participle forms chiefl y in North American English, (4) they have regular variants. The initial plan included all irregular verbs but the extent of the problem coupled with the editorial limitations as to the size of the paper led to the following decisions: first, to exclude the irregular strong verbs and save them for later analyses, and then, in the remaining irregular weak ones, to remove all those with vowel alternations (like keep, seek, lose, say) and to concentrate on the verbs without vowel alternations (investigated in the present paper). It is hoped that the aims of this paper as well as their realization can serve to make the content of the historical grammar course more meaningful to students by linking it to the problems present in Modern English and to the why-questions related to the subject of their studies.

The quantitative evaluation of environmental impact of emission sources is an important step of integrated modeling and the air quality decision support. The problem is especially difficult in the case of a complex, multi-source emission field. The approach discussed in the paper is based on the forecasts of the Eulerian type models of air pollution transport. The aim is to get a quantitative assessment of the contribution of the selected sources, according to the specified, environmental objective function. The approach utilizes the optimal control technique for distributed parameter systems. The adjoint equation, related to the main transport equation of the forecasting model, is applied to calculate the sensitivity of the cost function to the emission intensity of the specified sources. An example implementation of a regional scale, multi-layer dynamic model of SO, transport is discussed as the main forecasting tool. The test computations have been performed for a set of the -major power plants in a selected industrial region of Poland.

Liquid-gas flows in pipelines appear in many industrial processes, e.g. in the nuclear, mining, and oil industry. The gamma-absorption technique is one of the methods that can be successfully applied to study such flows. This paper presents the use of the gamma-absorption method to determine the water-air flow parameters in a horizontal pipeline. Three flow types were studied in this work: plug, transitional plug-bubble, and bubble one. In the research, a radiometric set consisting of two Am-241 sources and two NaI(TI) scintillation detectors have been applied. Based on the analysis of the signals from both scintillation detectors, the gas phase velocity was calculated using the cross-correlation method (CCM). The signal from one detector was used to determine the void fraction and to recognise the flow regime. In the latter case, a Multi-Layer Perceptron-type artificial neural network (ANN) was applied. To reduce the number of signal features, the principal component analysis (PCA) was used. The expanded uncertainties of gas velocity and void fraction obtained for the flow types studied in this paper did not exceed 4.3% and 7.4% respectively. All three types of analyzed flows were recognised with 100% accuracy. Results of the experiments confirm the usefulness of the gamma-ray absorption method in combination with radiometric signal analysis by CCM and ANN with PCA for comprehensive analysis of liquid-gas flow in the pipeline.

Within the INMOP 3 research project, an attempt was made to solve a number of problems associated with the methodology of modelling travel in urban areas and the application of intermodal models. One of these is the ability to describe the behaviour of transport system users, when it comes to making decisions regarding the selection of means of transport and searching for relationships between travel describing factors and the decisions made in regard of means of transport choice.

The paper describes a probabilistic approach to the determination of modal split, and the application of a logistic regression model to determine the impact of variables describing individual and mass transport travels on the probability of selecting specific means of transport. Travels in local model of Warsaw city divided into 9 motivation groups were tested, for which ultimately 8 models were developed, out of which 7 were deemed very well fitted (obtained pseudoR² was well above 0.2).

The Arctic takes in part of Russia, Canada, Norway, Sweden, Finland, Alaska (USA), Greenland (an autonomous Danish territory), Iceland and the Arctic Ocean, which is covered with ice and constitutes the center of the Arctic. There have been disputes between Denmark, Canada, Norway, Russia, and the USA concerning the borders o f the continental shelf of the Arctic Ocean. The author describes the achievements of the Russian expedition, “Arctic 2007, ” and the way in which Russia uses the 1982 Convention on the Law of the Sea. The essay also describes how the convention regulates the problem of the border of the continental shelf. He considers that in the future it may come to the partitioning of the Arctic Ocean’s continental shelf, along with the simultaneous fixing of “concessions” allowing the use of shipping lanes in the Arctic by the international community.

The main objective of this investigation is to assess the feasibility of strengthening of corroded (damaged) square hollow steel tubular sections subjected to compression and to develop or predict the suitable wrapping scheme of fibre reinforced polymer (FRP) to enhance the structural behaviour of it.For this study, compact mild steel tubes were used with the main variable being FRP characteristics. Carbon fibre reinforced polymer (CFRP) fabrics was used as horizontal strips (lateral ties) with other parameters such as the number of layers and spacing of strips. Among fourteen specimens, six were externally bonded by CFRP strips having a constant width of 50 mm with a spacing of 20 mm and the remaining six were externally bonded by CFRP strips having a constant width of 70 mm with a spacing of 20 mm, two columns were unbonded. Experiments were undertaken until the failure of columns to fully understand the influence of FRP characteristics on the compressive behaviour of the square sections including their failure modes, axial stress-strain behaviour, enhancement in the load carrying capapcity, and effect of distribution of CFRP layers. Finally, the behaviour of externally bonded hollow tubular sections was compared with one another and also with the control specimens. Evaluation of the results will lead to optimum CFRP jacketing/wrapping arrangements for the steel tubes considered here.

Sobór Watykański II, który był największym wydarzeniem we współczesnej historii chrześcijaństwa, zainicjował proces otwarcia i reformy Kościoła katolickiego na niespotykaną dotąd skalę. Przez trzy lata dyskutowano na temat najważniejszych tematów, zarówno natury czysto teologicznej i eklezjalnej, jak i pastoralnej i misyjnej. Jednym z tych soborowych tematów było także ożywienie braterskich relacji między katolikami i nie-katolikami. W artykułe dokonano analizy jednego z najważniejszych teologicznych tematów, który niestety pozostał w wyniku soborowej i postsoborowej dyskusji przeszkodą w rzeczywistym dialogu o przywróceniu jedności między katolikami a prawosławnymi. Jest nim prymat papieski, który prawosławni postrzegają jako wynik ludzkiej inwencji, pozbawionej solidnych biblijnych i patrystycznych podstaw. Ternin ten pojawił się po 1054 roku jako podstawowa cecha polityki religijnej związanej z prymatem Rzymu. Kościół prawosławny wierzy w możliwość przywrócenia jedności chrześcijan, jednak nie zgadza się na interkomunię bez uprzedniego osiągnięcia jedności w wierze. Stąd też oczekuje się od Kościoła katolickiego decyzji porzucenia roszczenia prymatu i papieskiej nieomylności bądź też ich przekształcenia zgodnie tradycją pierwszych wieków. Również oczekuje się redefinicji relacji między biskupem Rzymu a kolegium katolickich biskupów w sensie rzeczywistej i efektywnej synodlaności.

The article analyzes the content of the first (single) issue Phoenix, a magazine of esoteric philosophy published in 1937. Its selection of philosophic and literary works was (co)edited by Wacław Liwski, an esotericist and popularizer of the theosophical thought of Helena Roerich. Liwski is linked by some with the novelist Władysław Reymont.
