Abstract

This study examined the effects of UV-B radiation and allelochemical stress induced by ferulic acid (FA) on the activity of phenylalanine ammonia lyase (PAL; EC 4.3.1.5) at metabolic and molecular levels in two cucumber genotypes differing in tolerance to cold and disease, in order to determine any interaction between stress effects and genotype response. Stresses were applied simultaneously, sequentially, and singly. In both genotypes, several days of UV radiation retarded growth up to 36%. The effect of FA was not significant. The response to a particular stress, including the effect on PAL activation, was enhanced by simultaneous application of the two stresses. PAL transcription was not correlated with the increase of PAL activity. Exposure to UV-B, FA, and combined UV-B and FA was detrimental to both genotypes but to different extents. The response was not correlated with the genotype of cold and disease sensitivity. PAL activity and its transcription seem to be involved in UV and allelochemical stress, but not related to the plants' tolerance of these stresses.

Abstract

This paper presents for the first time X-ray computed microtomography (μCT) analysis as a technique for Silurian graptolite detection in rocks. The samples come from the Jantar Bituminous Claystones Member of the Opalino core, Baltic Basin, northern Poland. Images were obtained with spatial resolution of 25 μm, which enabled the authors to create a 3-D visualization and to calculate the ratio of fissure and graptolite volume to the total sample volume. A set of μCT slices was used to create a 3-D reconstruction of graptolite geometry. These μCT slices were processed to obtain a clearly visible image and the volume ratio. A copper X-ray source filter was used during exposure to reduce radiograph artifacts. Visualization of graptolite tubaria (rhabdosomes) enabled Demirastrites simulans to be identified. Numerical models of graptolites reveal promising applications for paleontological research and thus for the recognition and characterization of reservoir rocks.

Abstract

For over twenty years psychologists have been using information and communication technology to design solutions aimed at improving mental health and quality of life of their clients or patients. One of those solutions are internet interventions. Although these interventions are commonly used in other countries, knowledge about them in Poland is limited. The aim of the article is to introduce to the topic of psychological internet interventions by describing the basic functionalities of internet interventions, the context of their use, their classification, areas where they can be applied and challenges related to their future development and wider implementation.

Abstract

Jeśli spojrzymy na strukturę urbanistyczną Warszawy poprzez ocenę wartości historycznych założeń przestrzennych, tych które wiążą miasto z najcenniejszymi osiągnięciami urbanistyki europejskiej, to niewątpliwie w środowiskach profesjonalnych barokowe założenie Osi Saskiej znajdzie się wśród najczęściej dostrzeganych i wymienianych. Jak wiadomo, w swojej koncepcji nawiązuje ono bezpośrednio do Wersalu, gdzie rezydencja królewska, kompozycja ogrodowa i nowo rozplanowane elementy struktury miasta tworzą współosiową, wielkoprzestrzenną kompozycję o nieskończonych, dalekich zasięgach. Badania historyczne potwierdzające związek obu tych założeń, właśnie na ich wspólne odniesienia ideowe i formalne zwracają szczególną uwagę. Podkreślają „nieskończony”, zachodni zasięg kompozycyjny Osi Saskiej przedłużony w układzie ról dalekiej Woli, oraz równie dalekie otwarcie w kierunku wschodnim, którego kontynuację przekraczającą wnętrze Krakowskiego Przedmieścia i skarpę dostrzega się w przedłużeniu koryta starorzecza Wisły i związkach z otwartym krajobrazem brzegu Pragi, wówczas jeszcze słabo na tym odcinku zurbanizowanym.

Abstract

International law reflects systemic conditions compatible with its essence, which means that a space must exist inside the borders of that order for the presence of the phenomenon of general principles. The assumption that international law is a legal system ipso facto means that general principles must exist within its borders. A general principle of law is a necessary element of every legal order. It is a form and a tool in which the efforts of the individual seeking to comprehend a given phenomenon are materialized through imposing order on it rather than by breaking it down into unconnected and independent elements. Since law is an expression of order, law therefore applies general principles. The systematicity of law, and therefore of international law as well, creates the primary source of the binding force of any norm. Considerations of natural law or positive law justifications for the presence of general principles in international law are of little consequence, as the source of general principles is the systemic nature of the law. Order and hierarchy are part of the rationalized system in which norms of law present themselves. This dependency applies also to norms of international law. The role of the judge is to fill in the appropriate normative content (general principles) in fields constituting at one and the same time both a necessary element and a consequence of the systemic character of the international legal order. Within this context the principle of good faith constitutes one of the bases for considerations concerning the extent of the international legal order. The extent of international law reaches as far as the extent to which evidence of good faith are present among the subjects of international law. The impossibility of describing relations between two states by the use of the determinants of good faith, translated in turn into a normative general principle, determinates the limits of international law.

Abstract

Historic title is just one of many legal instruments which may be raised by parties and used by judges to decide a territorial dispute. If a claim of historic title in given circumstances may be deemed to have been extinguished as a result of its relative weakness, the elements advanced in support of its construction, for example uti possidetis or eff ective occupation, may be used to support other types of legal claims. Taking into account its construction and its systemic conditional criteria, historic title gains maximum eff ectiveness when conditions exist which would support a fi nding of its incremental consolidation. This involves a multi-dimensional interpretation in reliance on particular elements which, taken together, create a complicated factual state in a particular territorial dispute. On the other hand, consolidation of historic title is not an argument which can be used by the indigenous native inhabitants of a territory, since their arguments are not based on claims of sovereignty.
