Opis:
The preparation and use of remote experiments in the education system consists of the solutions of two, at first glance, single and independent issues. The first one, on the part of the provider – the admin-istrator of the remote real experiment, is a solution of technical design for the remote experiment and consequently its implementation. The second one, on the part of the remote experiment user, is a solu-tion of the tasks related to didactics of the application of remote experiment in the different stages of a lesson. To achieve a positive educational effect from the application of remote experiments in education, solution of didactic tasks is as important as solution of technical design of the experiment. The authors in this paper propose a procedure for making solutions, implementation and operation of remote experi-ments. They come to the conclusion according to which maintaining the long-term functionality and regular innovation of the remote experiment has the nature of the development spiral. They define the essential role of pedagogical research in relation to the application of remote experiments in education. In addition, they refer two examples of technical solution of remote experiments, in which for the con-trol and management, the programmable logic controller (PLC) is used.

Opis:
This paper presents research that has been carried out to analyze a relation between implementation of simple experiments in teaching sciences, and pupils’ positive attitude towards learning physics. Investigation was conducted on a random sample of 495 sixth – and seventh-grade pupils from primary schools in Novi Sad. The obtained results are statistically treated. Analysis of results shows that the use of simple experiments for a particular case is related to pupils’ attitude toward learning physics. Also, it is shown that approximately twice higher percentage of pupils that were taught with the use of hands-on experiments like to learn science than pupils who were taught with the use of demonstration experiments or without experiments. They do not learn by heart, they understand science and it helps them to develop a scientific world view that makes it easier for them to find their way in today’s world.

Opis:
Design of experiments methods are an important tool to improve production processes using statistical methods. Designing experiments allows to set factors of the production process as well as describe the influence of factors on the results. Furthermore, the design methods of experiments help to improve economic results of the analyzed process. The aim of this paper is the issue of choosing the optimal layout of experiments when the experimenter, because of the cost or conditions, has no possibility to implement the completion of the design of experiments. The method to determine successively points of a design will be suggested to carry out an experiment. Finally, implementation of the mentioned method will be presented for selected factorial designs.
Metody planowania eksperymentów są istotnym narzędziem doskonalenia procesów produkcyjnych wykorzystującym metody probabilisyczne i statystyczne. Planowanie eksperymentów pozwala na odpowiednie ustawienie parametrów procesu produkcyjnego oraz określenie wpływu czynników na jego wyniki. Ponadto metody planowania eksperymentów umożliwiają poprawę ekonomicznych rezultatów badanego procesu. Przedmiotem niniejszego artykułu jest zagadnienie wyboru optymalnego układu doświadczeń wówczas, gdy eksperymentator, ze względu na koszty bądź warunki, nie ma możliwości realizacji kompletnego planu doświadczeń. Zaproponowana zostanie metoda wyznaczania kolejnych punktów planu, w których należy przeprowadzić doświadczenie. Zastosowania prezentowanej metody przedstawione zostaną dla wybranych planów eksperymentów czynnikowych. Własności metody zostały sprawdzone w analizach symulacyjnych.

Opis:
The contemporary demands in different branches of engineering require application of new multi-component materials and structural systems. Appropriately chosen joining technology can offer significant enhancement of structural system performance in terms of effectiveness, reliability, safety and other design criteria. The modern applications of complex joints are of great technological interest as they permit to combine and to enhance the individual effects of each kind of joint. This is of great importance for modern applications in different branches of engineering: aerospace, mechanical and civil. Therefore in this paper we will focus on the analysis of mechanical response of adhesive joint of aluminium strips reinforced by rivets. The aim of the paper is to investigate experimentally the mechanical behaviour of adhesive joint of aluminium strips reinforced by rivets for industrial applications in aerospace. The considered joint was subjected to uniaxial loading. The tests in this paper were performed for: • classical adhesive joint in order to investigate material parameters for numerical modelling of the hybrid joint • hybrid joining of the structural elements in order to investigate the reinforcement effect. The experiments with application of digital image ARAMIS system allowed for on-line monitoring of the deformation process of the considered joining elements. The particular distributions of displacement fields at the joint surface were estimated for any stage of loading process. Numerical modelling was performed for experimentally investigated specimens. The materials parameters, necessary for calculation, were estimated from experiments. FEA modelling was done with the help of ABAQUS code.

Opis:
The paper concems laboratory experiments on shallow water waves. The waves in our flume were generated as programmed groups, with gentle fading-in and fading-out of amplitudes of the wavemaker's piston's motions. The higher harmonic components have been considered in the motion. Their influence on characteristics of generated waves has also been studied. The measurements were carried out at 6 cross sections along the propagation path; both wave profiles and velocities were recorded. As a description of phenomena, the wave profiles were approximated by harmonic com-ponents according to the Stokes solution. It was noted, that parameters of harmonic components change along the propagation path; there are energy transfers between them. The higher harmonic components are more significant for the description of wave profiles, than for the velocities. The results of the experiments were used in verifications in a research program on the theoretical description and numerical al-gorithm for shallow water waves generated and propagated in a flume.

Opis:
In case of the private procurement auctions the entrepreneurs are not forced to limit themselves to the standard auction rules, and in practice one can observe many hybrid or quasi-auction mechanisms spontaneously introduced. The paper analyzes two of them, which start as a first-price sealed-bid auction, followed by a run-off in a form of an English auction, and which differ by the transparency of rules concerning the initiation of the second stage. The focus of the paper is on the analysis of the price and allocative efficiency of these mechanisms, in order to determine whether they can serve as an alternative to the standard auction rules. Theoretical analyses are followed by the laboratory experiments, which demonstrate that the mechanisms under study are characterized by both high price and allocative efficiency, and therefore could be considered an interesting substitute of the standard auction rules.

Opis:
In this paper, the authors focus on the proposition of an innovative semi-active linear damper prototype working on the basis of granular materials. Vacuum Packed Particles (VPP) belong to the class of materials whose mechanical (rheological, dissipative) properties may be quickly changed by applying a partial vacuum inside the system. The concept of an innovative linear damper based on VPP is presented in the paper. Typical experimental results are presented to reveal changeable damping characteristics of the device. Additionally, the mathematical model is proposed to capture extraordinary features of the investigated damper.

Opis:
Reprocessing of spent nuclear fuel usually employs the solvent extraction technique to recover fissile material, isolate other valuable radionuclides, recover precious metals, and remove contaminants. Effi cient recovery of these species from highly radioactive solutions requires a detailed understanding of reaction conditions and metal speciation that leads to their isolation in pure forms. Due to the complex nature of these systems, identification of ideal reaction conditions for the efficient extraction of specific metals can be challenging. Thus, the development of experimental approaches that have the potential to reduce the number of experiments required to identify ideal conditions are desirable. In this study, a full-factorial experimental design was used to identify the main effects and variable interactions of three chemical parameters on the extraction of protactinium (Pa). Specifi cally we investigated the main effects of the anion concentration (NO3 –, Cl–) extractant concentration, and solution acidity on the overall extraction of protactinium by 2,6-dimethyl-4-heptanol (diisobutylcarbinol; DIBC) from both HCl and HNO3 solutions. Our results indicate that in HCl, the extraction of protactinium was dominated by the solution acidity, while in nitric acid the extraction was strongly effected by the [DIBC]. Based on our results, a mathematical model was derived, that describes the relationship between concentrations of anions, extractant, and solution acidity and the expected values of Pa distribution coefficients in both HCl and HNO3. This study demonstrates the potential to predict the distribution coefficient values, based upon a mathematical model generated by a full-factorial experimental design.

In terms of extending the application of remote experiments, an interesting method is the creation of community networks on the Internet with associations of educational institutions. In this article authors focused their attention on the formulation and application of remote experiments in education, in terms of their availability on the Internet and Intranet.

Opis:
Savitzkaya, hardly known to French public, delights contemporary readers with his style, displaying both peculiar and variegated characteristics. Although he dispenses with the matters of genre, his latest texts (Célébration d’un mariage improbable et illimité, 2002, Exquise Louise, 2003, Fou trop poli, 2005) are still thought to represent the novel. His peculiarity lies in that he contrasts a daily routine with brilliantly worked form, nevertheless well suited to depict it. His predilection for language is pervasive in his style, showing strong preference for details (still, it stands in a stark contrast to the practice of the Nouveaux Romanciers of the 20th century). Savitzkaya asserts himself with the aid of conciseness, draws to a large extent upon surprising stylistic devices, juggles with words, even if paying careful attention to their precision. Finally, he acts as a genuine poet, reviving fragrances and colors of childhood. All in all, the whole of his work is designed to bring his readers to take pleasure in living.
