Opis:
This article aims to discuss the objectives and instruments of the European regional policy with particular reference to the current period of its programming. Programming is a particular feature of the implementation of the Community policy, therefore this study is also intended to present a short overview of the programming of this policy in Poland. The main information about the existence and evolution of European regional policy is presented. Special attention is given to its political programming (tasks and spheres of financial intervention), especially budget programming. The main purposes of solidarity policy in Poland are presented. Its programming tools which are implemented according to the main document, which characterises directions of financial support from the EU, are given. This document entitled the National Strategic Frames presents a diagnosis of the social and economic situation of the country and the intentions of its regions towards development of solidarity. It contains a chapter about financial resources sharing according to operation programs as well as a description of the realization system.

Opis:
In this study, physical and functional properties of the cement composites containing ZnO, ZnO/lignin and lignin admixtures were investigated using Response Surface Methodology (RSM). The I-optimal design based on RSM was used to assess the influence of ZnO-based doping agent, of either commercial or synthetic origin, on cement composite production in the function of average compressive strength and cost. Polynomial mathematical models were developed by RSM confronting results from the experimental design. The accuracy and precision of the utilized models established by I-optimal design were tested using Analysis of Variance (ANOVA). The first stage of formulation optimization revealed that the use of commercially available ZnO-based admixture no. 4 (ZnO-SA, supplied by Sigma Aldrich) allowed to achieve the desired results, passing all the requirements, i.e., the best microbial purity combined with reasonable cost, followed by satisfactory physical properties. In the second stage of formulation optimization, the influence of implementing the hybrid materials, i.e., ZnO-SA mixed in different proportions with lignin was evaluated. RSM revealed that doping admixture no. 3, i.e., ZnO-SA/lignin (5:1), is the best candidate, which comprised augmented functional and physical properties of the fabricated cement composite. This component exhibited the best microbial purity as well as the lowest total pore volume, followed by satisfactory physical properties. Verification of the model findings indicated considerable agreement between the predicted and experimental values. From the findings, it was confirmed that a reasonable cost-performance balance for cement composites can be achieved using ZnO-SA and ZnO-SA/lignin (5:1).
