The purpose of the author was to indicate the deficiency of development management instruments currently used to the territorialization of policies in stimulating intra- and intersectoral partnership cooperation. Her reflections were based on the results of research commissioned by the Polish Ministry of Development and Investment by a team in which the author participated. These studies have revealed that the weakest impacts of the so-called territorial instruments include the ability to mobilize various stakeholder groups to take action and to create partnership cooperation. Against this background, the author has undertaken the analysis of the potential impact of territorial tools on the partnerships development and has attempted to present recommendations for practice and further research in this area.

A theoretical method has been presented to describe sound decay in building enclosures and to simulate the room impulse response (RIR) employed for prediction of the indoor reverberation characteristics. The method was based on a solution of wave equation having the form of a series whose time-decaying components represent responses of acoustic modes to an impulse sound source. For small sound absorption on room walls this solution was found by means of the method of variation of parameters. A decay function was computed via the time-reverse integration of the squared RIR. Computer simulations carried out for a rectangular enclosure have proved that the RIR function reproduces the structure of a sound field in the initial stage of sound decay suffciently well. They have also shown that band-limitedness of the RIR has evident influence on the shape of the decay function and predicted decay times.

Heat exchangers are widely employed in numerous industrial applications to serve the heat recovery and cooling purpose. This work reports a performance analysis of a tube in tube heat exchanger for different flow configuration under variable operating conditions. The experimental investigation was performed on a U-shaped double pipe heat exchanger set up whereas Commercial Computational Fluid Dynamics code FLUENT along with k-ε turbulence modeling scheme was implemented for the simulation study. The flow solution was achieved by implementing k-ε turbulence modeling scheme and the simulation findings were compared with the experimental results. The experimental findings were in good agreement with the simulation results. The counter-flow configuration was found to be 29.4% more effective than the co-current one at low fluid flow rate. Direct relationship between heat transfer rate and flow rate is observed while effectiveness and LMTD showed inverse relationship with it. The significance of inlet temperature of hot and cold stream has been evaluated, they play crucial role in heat exchange process.

This article deals with the rise in the Polish literature of 1970s of a new type of biographical novel, associated with the fi rst post-war generation of writers like Bohdan Zadura, Julian Kornhauser, Adam Zagajewski, Henryk Lothamer, Stanisław Piskor and Donat Kirsch. Their work is subsumed here under the label ‘new fi ction’ primarily because of its literary context, i.e. the late-modern fears and uncertainties culminating in the assumption that literature reached the state of exhaustion. The article argues that the ‘new fi ction’ acquired its distinctive character from a preoccupation with the biographical narrative and a sense of generational identity. The writers who defi ned themselves in these generational terms saw their prospect of following their aspirations and building up authentic lives weighed down by the constricting realities, and, as the article claims, resigned themselves – at best not entirely – to this sad conclusion.
