The objective of the article is to examine the approximative and adjustive uses of the verb dire, which is mostly regarded as an assertive and eventful verb; hence nonapproximative. Meanwhile, in many expressions, in an impersonal use, in negation when the subjunctive mode is used, in the conditional forms, its evidence value is weakened and the verb dire can express approximation. The study is situated in light of the enunciation theory, notably it refers to a notion of modalisation. The corpus was established on the basis of dictionaries, which are representative for normative uses, but we will refer as well to press texts, particularly interviews, where the verb say is frequently used as a marker of the position of the speaker.
One of the challenges of modern crystallography of complex systems (complex metallic alloys, proteins, aperiodic crystals and quasicrystals) is to properly describe the disorder in these systems and discuss correctly the refinement results in terms of the structural disorder. In this paper we briefly discuss a new approach to phasons and phonons in quasicrystals and focus on the new theory of phonons in these materials. A newly derived correction factor for phonons in the form of the Bessel function is the approximated way of describing optic modes in the phonon spectra of quasicrystals. It is applied to a real decagonal quasicrystal in the Al-Cu-Rh system with 56/38 atoms per thick/thin structural unit, based on 2092 unique reflections selected from the collected diffraction data, significantly improving the refinement results. The final R-factor value is 7.24%, which is over 0.5% better result comparing to originally reported. We believe our work will open a broader discussion on the disorder in quasicrystals (and other aperiodic systems) and motivate to develop new approaches to treat the diffraction data influenced by different types of disorder in the new way.
On the basis of 35 one-hour series of the measurement of the wind velocity, read out every two minutes, the wind structure at the Arctowski Station, situated on Admiralty Bay, King George Island, was analysed. Very strong turbulence was found with air flow directions from over the area of the Island (S, SW. W and NW) and laminarity with directions from SE, E, NE and partly N, i.e. when the air flows from Admiralty Bay or from over the open waters of Bransfield Strait. The qustiness coefficient, the relationship between the maximum and mean velocities and the intensity of turbulence were determined for the two flow types. Two extremely different cases, in terms of flow character, were considered, by determining for them the distributions of instantaneous velocities and those of oscillations.
Power spectrum techniques were applied to two time series of wind speed values recorded at the Arctowski Station in order to investigate the influence of turbulent and laminar air flow on the quasi-periodicity of the micro-scale wind structure.
Seismic refraction studies on Central Spitsbergen have shown that there is the fault systems with north-south strike directions, which divide the crust into western, central and eastern blocks. Thickness of the crust in this area varies from 35 to 40 km. Interpretation and modelling of seismic refraction data indicate that the Moho boundary beneath the Central Spitsbergen Basin is a complicated transition zone between crust and upper mantle with the thickness of about 5 km.
The presence of Euphausia superba, E. crystallorophias and Thysanoessa macrura was observed in Admiralty Bay (King George Island, South Shetland Islands) and the size of individuals of particular species are diverse and varying during the summer season. E. superba population is older and specimens larger than in analogous season in 1979. The maximum number of females with eggs was noted in the first half of January 1980, i.e. earlier than in 1979. In E, crystallorophias population the presence of females with eggs was observed in the second half of December 1979.
The location, geological structure and characteristics of the Kamionki Anticline is presented in terms of possibility of underground CO2 storage. It is situated in the Płock Trough, in the SW part of the Płońsk Block, and represents a synsedimentary graben originated in the Early and Middle Jurassic. It has been explored by a semi-detailed reflection seismic survey and three deep boreholes (Kamionki 1, Kamionki 2 and Kamionki IG-3). Assuming that the anticline is conventionally outlined by a contour line of the top of the Lower Jurassic, its length is about 15 km, width is about 5 km and the area reaches approximately 75 km2. Geological, seismic and reservoir property data allow concluding that this structure is suitable for underground carbon dioxide storage. The primary reservoir level for underground CO2 storage is represented by Barremianmiddle Albian deposits of the Mogilno Formation with an average thickness of 170 metres, containing on the average 85% of sandstones, and showing porosity of about 20% and permeability above 100 mD up to 2000 mD. The sealing series is composed of Upper Cretaceous marls, limestones and chalk reaching the thickness of about 1000 metres. The secondary reservoir level is represented by upper Toarcian deposits of the Borucice Formation.
A theoretical approach was applied to investigate the impact of nonlinear standing waves underneath a horizontal deck. A solution was achieved by applying a boundary element method. The model was applied to predict impact pressure underneath a deck. The results show that the wave impact is a very complex momentary process. The influence of initial boundary conditions, wave parameters and deck clearance on impact pressure are analysed. The analysis shows that purely sinusoidal waves of very small amplitude may cause an impact pressure several orders of magnitude higher than a pressure arising from typical applications of a linear wave theory. The analysis shows that all these non-intuitive outcomes arise from the complexity of a wave impact process and its enormous sensitivity to initial conditions what indicates serious difficulties in a reliable prediction of a wave impact for complex wave fields or other structures. Laboratory experiments were conducted to validate theoretical results.
An effective method for the analysis of soil-structure interaction including the behaviour of cylindrical storage tank with varying wall thickness under the action of constant thermal loading is presented. Elastic half-space and the Winkler model have been used for the description of subsoil. The soil-structure interaction is described by using the power series. A computational example of reinforced concrete tank loaded with constant temperature is given. The analysis of a hydrostatically loaded cylindrical tank performed for the model incorporating elastic half-space shows decrease of radial displacements as well as substantial changes in the distribution of bending moments when compared to the Winkler foundation. Additionally, local increase of subsoil reaction around the slab circumference is observed for the case of elastic half-space, in contrast to the Winkler model. However, in the case of a tank loaded with constant temperature, the solutions for both subsoil models do not differ significantly.
The first post-war, comprehensive Gdynia Downtown Plan was at the same time one of the first spatial development plans in Poland defining the directions of transformation of multifunctional downtown structures in the new system and legal realities. It was the Plan of the Polish Breakthrough related to the realities of the downtown area of Gdynia. The study area included the Gdynia Valley limited by the hills of Kamienna Góra, Redłowo and Chylońskie Forests with the development of a complete pre-war city developing in accordance with the fi rst plan of Adam Kuncewicz from 1925 in the zone of 3 km, counted from the center of the inner port. The aim of the plan was to look for centralizing potential in the fi eld of research. This concept was treated as a power degree related to the then existing state, as well as the possibility of further development or transformation.
The selection of appropriate financial sources by enterprises is one of the key tasks faced by the management board. In the presented article, the Authors decided to verify the capital structure of companies from selected European economies and to compare this capital structure between developed and advanced developing markets. The research was conducted on 18 European economies, taking into consideration data for 2017 and five variables defining the structure of financing. The results of the analysis show that the economies in the basket of developed countries are characterised by a higher level of indebtedness, with the major difference in taking on interest-bearing liabilities.
Rocks of the Legoupil Formation in the Cape Legoupil area were folded about a N70E oriented axis. Later these rocks were affected only by brittle deformation which occurred in four stages: (1) jointing — set I, (2) dyking, (3) faulting and, (4) jointing — set II. Both, folding and subsequent brittle deformation, are hardly compatible with the Mesozoic-Cenozoic eastward subduction of the ancient Pacific ocean crust.
This work attempts to reconstruct the culture that contributed to the philosophical way of thinking. My goal is to extract two important factors: religion carrying individual experience and the importance of certain ideas which are present in that culture. Sources of philosophical thinking can be found in the structure of polis. Only on its basis could the idea of the wise man and citizen as well as religion-oriented individual experience be raised. Greek polis paves the way for a new style of thinking by creating the conditions for its citizens to follow the ideal, regardless of the position they occupy in society. Sustainability, which should be a feature of a good citizen, is also the essence of society. Highly positioned wisdom as moral reflection tinged with religiosity allows thinking according to the laws of logos. Finally, the experience offered by the mystery cults leads to the transformation of their own existence and the emergence of a way of recognition of reality different than before. Undeniably, all the elements related to structure policies with its ideals contribute to the emergence of a new way of thinking in the form of philosophy. One could say that the philosophical objectivity is preceded by the subjectivity and rationality of its roots dating back to irrationality.
