Abstract

The paper shows the hybrid method of stress and strain distributions analysis. In the method, the results of displacement measurement were used as boundary conditions in the numerical analysis of the tested objects. The numerical analysis was performed with the use of the finite element method (FEM), whereas measurements of displacement were made by laser grating interferometry technique (moire interferometry). Examples of tests presented in the paper show good efficiency of the method in the analysis of stress and strain distribution in the areas of their heterogeneous distribution. Mutual completion of laser grating interferometry and finite element method makes it possible to exclude their disadvantages creating broader' possibilities for research impossible to achieve in separate use.

Abstract

In the chaotic situation following the British invasion of southern Palestine at the end of 1917, military officials faced several countervailing pressures. In addition to ongoing military priorities (including international norms pertaining to military occupations, such as the law of the ‘status quo’), pressing humanitarian concerns, and even the personal religious sentiments of individual officers, the British occupation administration was forced to take into account international pressures and interventions resulting from the overlapping and conflicting promises made during the war (inter alia, Sykes‑Picot agreement, Husayn‑McMahon correspondence, Balfour Declaration, and President Wilson’s 14 Points). This paper focuses on the land policy‑making process as a case study with which to weigh the various factors pressing upon the military occupation as it evolved during its first three years. Land ownership was a huge concern: a properly functioning land registry was seen as key to the improvement of economic and social conditions in the largely agricultural economy, and British interventions were followed closely by all interested parties. The land has also been at the centre of the ensuing century‑long conflict between Arabs and Jews. Thus, a close examination of land policies (and especially the 1920 land ordinance) offers an extremely important window on both the rule of law in the aftermath of the war and our understanding of the current, unending conflict in the land.

Abstract

The author reviews the main elements of Richard Münch’s academic capitalism theory. By introducing categories like “audit university” or “entrepreneurial university,” the German sociologist critically sets the present academic management model against the earlier, modern-era conception of academic research as an “exchange of gifts.” In the sociological and psychological sense, the latter is a social communication structure rooted in traditional social lore, for instance the potlatch ceremonies celebrated by some North-American Indian tribes which Marcel Mauss described. Münch shows the similarities between that old “gift exchanging” model and the contemporary one with its focus on the psychosocial fundamentals of scientific praxis, and from this gradually derives the academic capitalism conception. His conclusion is the critical claim that science possesses its own, inalienable axiological autonomy and anthropological dimension, which degenerate in result of capitalism’s “colonisation” of science by means of state authority and money (here Münch refers to Jürgen Habermas’s philosophical argumentation). The author also offers many of his own reflections on the problem, which allows Münch’s analyses to be viewed in a somewhat broader context.

Abstract

The paper deals with the properties and microstructure of Reactive Powder Concrete (RPC), which was developed at Cracow University of Technology. The influence of three different curing conditions: water (W), steam (S) and autoclave (A) and also steel fibres content on selected properties of RPC was analyzed. The composite characterized by w/s ratio equal to 0.20 and silica fume to cement ratio 20%, depending on curing conditions and fibres content, obtained compressive strength was in the range from 200 to 315 MPa, while modulus of elasticity determined during compression was about 50 GPa. During three-point bending test load-deflection curves were registered. Base on aforementioned measurements following parameters were calculated: flexural strength, stress at limit of proportionality (LOP), stress at modulus of rapture (MOR), work of fracture (WF), and toughness indices I₅, I₁₀ and I₂₀. Both amount of steel fibres and curing conditions influence the deflection of RPC during bending.
