A rich network of bodies of water fed by supraglacial streams has developed in the Hörbyebreen marginal zone due to intensive deglaciation. Most of them are lakelets of 0.1 to 1.0 ha in area and a mean depth of 0.3 to 1.3 m. They developed mainly after 1961. Studies were made of suspended and dissolved sediment concentration, and the ionic composition of the waters of proglacial streams and lakes, followed by an estimate of the balance of the proglacial transport of material. The calculation showed that the total net deposition of mineral material in the marginal zone amounts to 58.45 t per day. which constitutes 56.07 per cent of the total volume transported by proglacial streams. Borings proved sediments deposited in lakes at present to be of little thickness, ranging from 3 to 19 cm. As to litholology, there in a dominance of light-grey silty-clay deposits with a mean grain-size of 5.70 to 6.21 phi, sometimes with thin intercalations of coarse-grained sands and gravels. Chemical analyses shovedthat these deposits contain mostly silicates with small admixtures of Ca and Mg, and that they reflect the geological structure of the area.

The dynamics of economic development determines the need to develop technologies for waste recycling especially the acquisition of condensed fuels for the needs of the local diversification of energy sources. In a short time, Poland will probably lack its own produced electricity. To apply the process of diversification of energy sources, by developing methods of generating energy from waste, it becomes crucial to protect the environment. The use of cogeneration technology based on fuels derived from waste, in particular concentrated oil and gas fuels, is becoming more common and provides the basis for securing the energy supply in the preferred diversification process. Plastic waste processing in the controlled depolymerization process, which is the reverse of the polymerization process for hydrocarbon recovery – uses petroleum derivatives its production. At present, the greatest interest arises in the material recovery of plastics and rubber in the process of anaerobic thermal decomposition (thermolysis/pyrolysis), which is used on an industrial scale and consists in the degradation of polymer bonds into low molecular weight. The imperative of a modern economy is to obtain energy from fuels from waste treatment, including hazardous waste, preferably in the cogeneration process. The fuel obtained from waste may be used to obtain thermal or electric energy in order to diversify energy sources. The article presents innovative Polish technologies of obtaining fuel in processes of anaerobic thermal decomposition mainly of elastomeric and polymeric waste (including hazardous ones) for direct application in power generators of various power.

An overview of the bibliography regarding the connection of knowledge about precious metal alloys and aspects of the use of computer aided technologies to the optimization of the jewelry casting processes is presented. An analysis of the usability of selected CAx systems was made: 1) for spatial design, called Rhinoceros 6 and 2) CAE system: NovaFlow & Solid (NF&S). The authors describe own research including data acquisition and evaluation of temperature variations during solidification of the selected Au-Ag-Cu alloy, with the identification of the phase transformations of this alloy. The intensity of heat exchange was changed (cooling of specimens under ambient temperature conditions – "normal" intensity and with the furnace – very slow cooling). The problem of completing the simulation database was pointed out and analyzed. Examples of simulations of casting selected jewelry (ring and signet) were given and compared with the result of the experiment realized in real conditions. It was confirmed that the optimization by combining experimental and simulation studies allows for the acquisition of new knowledge, and also facilitates the creation of new artistic designs of jewelry as well as performing the feasibility check, and then optimizing the chosen technology.

Although currently pole dancing is growing in popularity due to its sport dimension, it seems that such a form of expression is still commonly associated with strip clubs and connotes above all the erotic performance of a woman in front of a male audience. And yet, as one can find by frequenting dance studios that teach pole dancing, it is practiced not only by women, but also by men and children. Thus keeping in mind the ambiguity that arises at the intersection of competing optics in decoding the pole dance—with regard to “perpetuate interpretation logic” and the everyday experience of people undertaking the activity—the aim of this paper is to reflect on the issue of constructing and interpreting the meanings of actions and processes within the context of pole dancing. These processes can be seen as a reflection of the everyday life in which they occur.

The work presented here, concentrates on experimental surface roughness analysis in the milling of hardened steel using a monolithic torus mill. Machined surface roughness with respect to milling process dynamics has been investigated. The surface roughness model including cutter displacements has been developed. Cutting forces and cutter displacements (vibrations) were measured in order to estimate their quantitative influence on Ra and Rz parameters. The cutter displacements were measured online using a scanning 3D laser vibrometer. The influence of cutting speed vc on surface roughness parameters (Ra, Rz) was also studied. The research revealed that real surface roughness parameters are significantly higher than those calculated on the basis of a kinematic-geometric basic model, and their values are strongly dependent on dynamic cutter displacements.

Pluralism and multiculturalism are new terms in biblical studies . Pluralism used in social sciences means a conditio of society in which members of diverse ethnic, racial, religious or social groups maintain their unique cultural identities. Multicultu-ralism focuses on interactions between different groups and communities within the confines of a common society. This paper aims at analysing the practice and models of pluralism in the Bible and the evaluation of pluralism in the biblical context (from separatism in the Abraham days until the multicultural Christian community in the first century). Christianity existed as a pluralistic community from the beginning. Paul the Apostle presents the Church as the body of Christ and interactions within the Chri-stian community consisting of Jews and Gentiles are illustrated by relations between members of the body. The mission of the Church is based on various models of incul-turation (contextualisation). All of these models intersect with one another in different ways. Pluralism in the biblical studies manifests itself also in the use of different Bible translation strategies and various methods of biblical exegesis and interpretation.
