Opis:
In the twentieth century, due to the development of mechanical reproduction and press, photomontage became a popular means of communication – popular and diverse in its nature and methods of exploitation (considering press in Germany or in the Soviet Union and individual works of art). It is one of the cultural phenomena related to the change of rhythm of life and a sense of its increased pace, and an impression of fragmentation of reality. This article questions the role of photomontage in such an experience. The said role is complex: sometimes photomontage allows for expression of that experience, and sometimes it is meant to evoke it, in the spirit of modernity; it is both a tool of agitation and critique. In order to answer this question I shall assume the approach of Walter Benjamin, who diagnoses the crisis of experience and the loss of storytelling skills – and describes the potential of photography. This potential is differently approached by artists and scholars who point out contradictory purposes and results of using photomontage. Referring to various works of art shall make it possible to define the tensions characteristic of photomontage. Due to its plasticity and the ambiguity of a photograph, and the potential for (de)contextualization and (de)construction, photomontage can function in a hard to understand, rapidly changing world and address the fragmentation of experience.

Opis:
Accurate measurement of blast fragmentation is important in mining and quarrying operations, to monitor blasting and optimize blast design. A new digital photoanalytical method to measure the size of fragments by using FragScan system is presented here. Photographs of the broken rock are digitized, and individual measurement, based on mathematical morphology techniques, achieves, within successive openings on a binary image, a numerical sieving. The method was tested during recent full scale blasting tests in the case of open pit gold mine of Amesmessa (Algeria). It shows great potential as a practical aid to predicting, monitoring, and controlling the quality of the fragmented rock.

Opis:
A new nonlocal discrete model of cluster coagulation and fragmentation is proposed. In the model the spatial structure of the processes is taken into account: the clusters may coalesce at a distance between their centers and may diffuse in the physical space Ω. The model is expressed in terms of an infinite system of integro-differential bilinear equations. We prove that some results known in the spatially homogeneous case can be extended to the nonlocal model. In contrast to the corresponding local models the analysis can be carried out in the $L_1(Ω)$ setting. Our purpose is to study global (in time) existence, mass conservation and well-posedness of the model.

Opis:
The accession to the European Union contributed to an increase in Poland’s foreign trade, and the growing export market is coupled with an increasing importance of intermediate imports, which is necessary to produce goods of appropriate quality and price. This phenomenon is a part of the process of fragmentation in global value chains. Fragmentation of the value chains should manifest themselves, in particular, in a multi-phase manufacturing process that requires many components of different types. In this paper, the recently available OECD database of the Trade in Value Added (TiVA) has been used to assess changes in the composition of gross exports of Poland and other Central Europe countries. In Poland, practically all sectors show a growing share of the imported value added. The cases analyzed confirm the thesis that the high technology sectors foster fragmentation. In the case of technologically lessadvanced sectors and short-value chains, benefits of fragmentation are limited. The progressing fragmentation and, as a consequence, a growing share of the imported value added made the gross export value (which is commonly used in statistics) of little use for the analysis of the economic role and competitive position of sectors. However, thanks to new projects based on I-O matrices of the global economy, it is possible to decompose gross exports into respective domestic and foreign value-added streams.

The Creeping Constitutionalization and Fragmentation of International Law: From “Constitutional” to “Consistent” Interpretation

Tematy:
fragmentation, constitutionalization, international law, legal interpretation
Opis:
This article considers the different interpretive methods used to deal with the phenomena of the constitutionalization and fragmentation of international law. While the technique of ‘constitutional’ interpretation has traditionally been developed and applied with reference to the UN Charter, the expansion of other constitutionally-oriented regimes at both universal and regional levels has multiplied the threat to the coherence of the international legal order, dramatically enhancing the problem of its fragmentation. To cope with this problem, the principle of systemic integration has been proposed as a legal panacea for the coordination of different normative layers of international law. Insofar as systemic integration aims at minimizing normative conflicts and is predicated on the presumption of compatibility between the different rules at stake, it can be posited that the principle of ‘consistent interpretation” represents one of its fundamental conceptual underpinnings. However, consistent interpretation as a legal technique has been traditionally conceived for a constitutional legal environment, and its application at the international level is likely to produce unintended ‘constitutionally-oriented’ legal effects. This article concludes that the various interpretive methods considered, through their dynamic of reciprocal interferences, operate in a creeping fashion to promote, rather paradoxically, both the constitutionalization and fragmentation of international law. As such, they are symptomatic of legal pluralism and of the complexities that characterize modern international law.

Opis:
The aim of the paper is to present the results of research on the influence of fragmentation warhead selected parameters on spreading capabilities. Fragmentation warhead is used to combat shaped charges and consists of metallic cover, explosive material and fragmentation liner. Fragmentation liner is built from metal balls or cylinders embedded in the resin. The explosives, initiated by a igniter, causes driving the liner in a few milliseconds up to about 900 m/s. The liner, as well as the case, fragments into many parts during this dynamic load. Geometric parameters of the fragmentation warhead affect the fragments velocity, their mass or geometric dimensions which are the most important parameters determining effectiveness of the warhead. In order properly to describe behaviour of fragmentation warhead arbitrary Lagrangian-Eulerian (ALE) and fluid-structure interaction (FSI) approach was used. In this method, the fragmentation liner is modelled using Lagrange description while the resin, the explosive charge and the surrounding air are modelled using Euler description. A three dimensional model of directed fragmen-tation warhead along with the fragmentation liner was prepared in MSC.Patran software and the dynamic phenomena analysis used a nonlinear finite element method implemented in the LS-DYNA program.

Opis:
The aim of the paper is to presents one of the possible approaches to the numerical analysis of the behaviour of directed fragmentation war heads. These kinds of warheads consists of: metallic or composite cover, explosive material and a driven and fragmentation liner. The explosives are initiated by a booster causes driving the liner in a few milliseconds up to about 900 m/s. The liner fragments into many parts during this intensive and dynamic load. The fragments move in a cone which dimensions depend on the warheads shape and mechanical parameters of others warheads parts. All of the warheads elements are selected to meet the assumed parameters. The fragments velocity, their mass or geometric dimensions and cone angle are the most important parameters of the warheads fragments. Such a warhead, in the initial phase of the liner driving can be numerically modelled in the field of the continuum damage mechanics. Such a description is presented in other papers. This approach in a further phase of driving cause the increases of inaccuracies. Therefore, this paper proposes the use of ALE and FSI approach to describe the behaviour of the fragmentation warheads. A three-dimensional numerical model of the directed fragmentation warheads was made in the MSC Patran, and the dynamic phenomena analysis used a nonlinear finite element method implemented in the LS-Dyna program.

Opis:
The paper explores and explains the fragmentation process in Croatian local government during the transition period from 1990 onwards. Special focus is given to the emergence of new municipalities (municipal splits/ secessions) that occurred after the new two-tier local government system was established in 1993. Excessive fragmentation of territorial structure at the beginning of the 1990s was a systematic and centrally driven reform that was meant to break with the inherited local government model and break up its territorial structure as radically as possible. While the initial overhaul in 1993 was mostly the result of conscious policy implemented in a top-down manner, subsequent municipal splits were mostly the outcome of local initiatives and lobbying, and were predominantly shaped by local, primarily economic factors, whereas political and cultural factors were of secondary importance. The national institutional context, including criteria and procedural rules for splits, were quite liberal during this whole period, with a moderate tightening-up trajectory. The number of municipalities finally stabilised in 2006, since when there have been no more splits.

Opis:
The calamity windstorm in November 2004 caused dramatic changes of land cover in the Tatra Mountains. The bora have destroyed then more than 12,000 ha of forest and principally affected the habitat structure in the Tatra National Park. The aim of this contribution is to quantify changes in forest fragmentation in 2000 and 2006. We present forest fragmentation maps related to the years 2000 and 2006. The CORINE Land Cover data layers CLC 2000 and CLC 2006 converted to raster format were used as the input data in the process of forest fragmentation assessment. Forest pixels were classified according to fragmentation indices measured within the surrounding landscape as the forest core, forest patch, forest edge, and perforated forest. Decrease of the compact forest areas (forest core) by about 9% was recorded. On the other side, increased percentage of disrupted forest areas was observed. Decrease of the area of the CLC forest classes (classes 311, 312 and 313) on land cover maps from 2000 and 2006 was connected with an increased number of transitional woodland/shrubs polygons (CLC class 324). These results suggest a temporary fragmentation with possible forest regeneration. On the other hand, forest destruction in the National Park facilitated the development of travel and tourism (new hotels, ski parks, etc.). An increased number of construction sites (CLC class 133) indicate that an urban sprawl associated with a permanent forest fragmentation can be also expected in the future.

Opis:
Unfavorable spatial structure of arable land located in Małopolska is a major obstacle in conducting agricultural activity. Arable lands located in the southern part of Małopolska are fragmented, have small area, and irregular shapes. Agricultural activity on land with an unfavorable spatial structure is associated with an increase in production costs, which directly results in lower income of farms. One of the methods of improving spatial conditions is to implement land consolidation works. They allow to organize the spatial structure, increase the area of agriculturally used parcels, while reducing their number. The article presents a new approach in determining the parameters of land fragmentation. GIS tools were used to identify areas with unfavorable spatial parameters. The methodology which allows for the processing, filtration of source data, determination and visualization of land fragmentation parameters is discussed. As part of the research, the Binning method was used, which allows to visualize the phenomenon and simultaneously reduce the data used. In the work, a detailed assessment of land fragmentation parameters was made, which can be used in agricultural land management works. Analyzes have shown that the southern areas of the Nowy Targ County are characterized by intensive fragmentation of arable land. There are also unfavorable parameters related to the elongation and shape of parcels in the discussed areas.
