Opis:
In the field of engineering protection, there is a structural disaster named heavy vehicles impacting column structures. When a heavy truck collides with a reinforced concrete (RC) column at a high velocity, a large impact force generated makes perhaps the column fail and even collapse. Therefore, it is necessary to study the dynamic characteristics during such a disaster, which can provide some reference for structural design, optimization and protection. The RC column impacted by a vehicle could be simplified as a beam fixed at the bottom loaded by a concentrated force, whose deformation is controlled by shearing and bending. In the present work, the ultimate static forces corresponding to shearing and bending collapse are proposed based on theoretical analyses. The model validation is performed using the finite element approach and the theoretical analytical results are in good agreement with the finite element simulation results, which validates the present analytical model. Three cases are simulated by utilizing finite element code ABAQUS, which reveals that the approximate plateau collapse force keeps a long stage beyond the peak failure one. In addition, three collapse modes are observed based on the static force and deformation analysis, validating the present framework which can be used for routine pier design. The work can be extended to estimate collapse modes of building columns under a vehicle collision.

Pier Giorgio Frassati (1901-25), the wife of the Polish diplomat Jan Gawroński (1892-1983), gave her abilities, courage and dedication to the Polish case during the Second World War. Although nobody commanded it, from September 1939 to December 1942, she visited the occupied Poland seven times. She contacted the representatives of the underground organisations and made many efforts to bring risky actions to a successful end. Among her actions we have to list: the release of a hundred people from the Gestapo, the transport of Gen. Władysław Sikorski's wife and daughter to the West, secret films, messages, notes, and the Warsaw telephone directory. She reported on those visits to Pope Pius XI as a spokeswoman of the Polish Church, and also during her six meetings with Benito Mussolini, as it was in the name of the Polish nation.

Opis:
Local scour around bridge piers impairs the stability of bridges’ structures. Therefore, a delicate estimation of the local scour depth is vital in designing the bridge piers foundations. In this research, MATLAB software was used to train artificial neural network (ANN) models with four hundred laboratory datasets from different laboratory studies, including five parameters: pier diameter, flow depth flow velocity, critical sediment velocity, sediment particle size, and equilibrium local scour depth. The outcomes present that the ANN model with the Levenberg-Marquardt algorithm and 11 nodes in the single hidden layer gives an accurate estimation better than other ANN models trained with different training algorithms based on the regression results and mean squared error values. Besides, the ANN model accurately provides predicted local scour depth and is better than linear and nonlinear regression models. Furthermore, sensitivity analysis shows that removing pier diameter from training parameters diminishes the reliability of prediction.

Recenzja książki Piotra Kletowskiego Pier Paolo Pasolini. Twórczość filmowa (2013). To pierwsza na polskim gruncie tak obszerna i wyczerpująca monografia reżysera uważanego za jednego z najwybitniejszych artystów kina światowego. Autorka koncentruje uwagę na metodzie badawczej Kletowskiego, który uwzględniając różne aspekty twórczej aktywności Pasoliniego (zwłaszcza dotyczące filmu i literatury), szuka równowagi między spójnością estetyczną i filozoficzną jego dzieł a immanentnymi paradoksami oraz sprzecznościami, które budują ich dynamikę. Toteż najważniejszym kluczem interpretacyjnym staje się tu dialektyka myśli chrześcijańskiej i marksizmu.
A book review of Piotr Kletowski’s Pier Paolo Pasolini. Twórczość filmowa [Pier Paolo Pasolini: His Work in Film] (2013). This is the first monograph of such width and richness to be published in Poland on a director considered to be one of the greatest artists of the world cinema. The author focuses on Kletowski’s research method, which takes into the consideration all kinds of aspects of Pasolini’s creative work (especially film and literature), and seeks to find a balance between the aesthetic and philosophical coherence of his work and their immanent paradoxes and contradictions, which drive its dynamics. In effect a dialectic between Christian thought and Marxism turn out to be the key to the interpretation of the work of the great master.

Purpose: Due to an increase in a number of bridges being constructed, scour depth around bridge piers is gradually being recognized as one of the possible reasons for bridge failure. According to [1] about 53% of bridge failures in the US were caused due to floods and corresponding scour in the rivers. Lots of work has been carried out around the single pier but in the case of group piers, the work is very less. Hence, it becomes necessary to calculate the actual scour depth around the bridge piers considering the close location of bridges as well. Design/methodology/approach: Recognizing the need for research in this direction, an experimental study was planned and conducted in the Hydraulics Laboratory of Civil Engineering Department of National Institute of Technology Kurukshetra, India. Experiments were conducted in a standard recirculating tilting bed water flume 15 m long, 0.4 m wide, and 0.60 m deep. The orientation of more than one pier, namely Tandem pattern was employed for the work. Two pier models, 62 mm and 42 mm diameter were used for the experimental study. The mobile bed used in the experiments had an average mean size, d50 = 0.23 mm, 0.30 mm and 0.50 mm. Findings: The outcomes of the ANN function and M5 model analysis have been used to compare with experimental results. From the earlier studies, it was concluded that, when the clear spacing between the pier models was greater than 0D the scour depth around the piers increase with a rapid rate. However, in the case of modelling techniques, M5 models show higher predictive accuracy than ANN models. Research limitations/implications: It is a significant area of research. However, the present study has been a time and facility- constrained study. Therefore, there is a large scope to conduct further studies on the subject, Different pattern i.e. Side by Side; Staggered and Group of piers can be adopted for further investigations. Originality/value: Sufficient work has been done by number of researchers around the single bridge pier. But due to rapid urbanization a number of bridges constructed in close proximity to each other which affects the scour depth of each other. Modelling techniques used in hydraulic engineering are not always effective in practice. The present study discusses the effect of spacing on scouring around piers in a tandem arrangement using experimental as well as modelling techniques. To predict the scour depth of the Tandem arrangement 89 laboratory data sets have been used.

Opis:
The hydrodynamic pattern, which surrounds the pier near a splitter that has T-shape, is investigated by adopting a numerical method and using ANSYS Fluent Software to achieve computation. The essential objective of this paper refers to revealing the behavior of the hydrodynamic field around the pier due to the existence of the upstream splitter plate. The T-splitter plate has not been used in previous works for controlling the flow field around the cylinder body. The main assumptions adopted in solving the hydrodynamic problem are incompressible, steady, and laminar flow. Reynolds number values are taken from 40 to 200 to guarantee laminar flow with laminar vortex street. The numerical investigation focuses on two main variables. These variables are the horizontal distance between the rear portion of a splitter and the pier center and bubble length. The numerical study comprises pressure contours, water velocity contours, and streamlines. Results reveal that bubbles are generated and developed due to the existence of the splitter. Four bubbles are generated, two of them are formed in the region between the splitter rear portion and pier leading portion and the other two bubbles are formed at the cylindrical pier wake region. The size and length of these four bubbles are dominated by the Reynolds number, these bubbles are non-symmetrical. It is revealed from the solution that with the rise in Reynolds number values then the disturbance will be increased simultaneously. The horizontal distance dominates the hydraulic response, which is described by the streamlines, pressure contours, and water flow contours. Furthermore, the Reynolds number has a significant influence on the pressure contours, water flow contours, and streamlines. Finally, a correlation equation is derived relying on bubble length, horizontal distance, and Reynolds number.

Opis:
The present analysis focuses on the investigation of the two-dimensional flow passing a bridge pier nearby a splitter plate in different regimes of a laminar flow. The splitter plate is T-shaped and two different cases have been studied based on the form of the splitter plate relative to the bridge pier. The analysis is implemented for steady and incompressible water flow in an open channel. The current study deals with velocity vectors, drag coefficients, lift coefficients, and skin friction. The analysis of the velocity vector gave a good indicator about the separation process and dissipation, which occurs at the splitter plate before the occurrence of these processes at the front face of the pier, especially the flow separation process. Moreover, the velocity vector gave a good image about the flow direction at two regions, the first region is located between the rear portion of the splitter plate and the frontal face of the pier, while the second region is the wake region, which is located at the downstream of the pier. Negative drag coefficient, lift coefficient, and skin friction coefficient values are obtained from the analysis. This happens due to the existence of the splitter plate that leads to the reduction of these values.

The aim of this paper is to reflect on Handke’s reception of Spanish and Friulian traditions. The first part of this paper will mention Miguel de Cervantes’, Teresa of Ávila’s and John of the Cross’ influence on Handke’s works, while also focusing on Handke’s fascination with the Spanish tradition and Pasolini’s works through the use of the comparative method. Pasolini’s vision of modern cultural customs is also taken into consideration in Handke’s Essay on the Jukebox, where clear references to Spanish authors also appear. The same occurs in Handke’s Glowworm Epopee, where Pasolini’s critical view of the “vanishing of the fireflies” indirectly shines throughout a tribute to the Poems in Casarsa. In the second section, an anthropological perspective will be employed, seeing as Handke’s ‘mysticism’ can be said to have drawn inspiration from the Romantic motif of “Mother Holle” (Höller 2013). In this regard, Ginzburg’s (1989) and Nardon’s (1999) studies will be used to assume Handke’s attachment to Friulian folk topics dating back to the 17th century. As opposed to Handke’s reception of Pasolini’s critical views and of Spanish mysticism, the influence of Friulian ethno-anthropological aspects on the Carinthian author’s works still needs to be demonstrated and its study improved.

Opis:
Although the complexities and irrevocable consequences associated with bridge scour have attracted researchers interest, their studies scarcely indicated the effect of a bridge pier proximity to an abutment. This research aims to measure maximum scour depth and exhibit the impact of pier-abutment scour interference based on laboratory experiments where vertical-wall abutment and two shapes of a pier (oblong and lenticular) were used at three different spacings (23.5, 16.0, 9.0 cm). The results showed an obvious increase in the scour depth ratio when increasing flow intensity, Froude number, and a decreasing flow depth. They also showed that reduced pier-abutment spacing was accompanied by increase in pier scour for both shapes while decrease in abutment scour. The maximum scour depth that caused by an oblong shape was more than a lenticular shape by about 10.8%. Furthermore, new empirical equations were derived using IBM SPSS Statistics 21 with determination coefficients of 0.969, 0.974, and 0.978 for oblong, lenticular and abutment, respectively. They showed the correlation between predicted and observed data.

Many port cities in Europe and America face the problem of finding new uses for old, unused wharves. Sometimes they are adapted for the purpose of storage, sometimes they are used as car parks. An interesting example of turning the old waterfront into on the park comes from Philadelphia. The project, which began in 2009 is considered as innovative and of great importance for the revitalization of Philadelphian waterfront.

Opis:
Twórczość Piera Paola Pasoliniego zawsze budziła kontrowersje i dzieliła publiczność na zagorzałych zwolenników oraz tych, którzy tę twórczość kategorycznie odrzucają. Lipowicz podejmuje próbę analizy oraz interpretacji ostatniego film Pasoliniego Salò, czyli 120 dni Sodomy (Salò o le 120 giornate di Sodoma, 1975) z filozoficznego oraz socjologicznego punktu widzenia. Stara się dowieść, że Salò jest niewygodnym i dlatego wyklętym arcydziełem kinematografii, które zarówno w sposób krytyczny, jak i pesymistyczny obrazuje przejście kultury zachodniej od nowoczesności do ponowoczesności. Ze współczesnej perspektywy dzieło to stanowi ważne upomnienie, aby pod płaszczykiem społecznej różnorodności nie zapominać o tym, że wciąż jako rzekomo wolni obywatele jesteśmy zmuszeni do życia i uczestniczenia w kulturze konsumpcyjnej, która nie tylko narzuca nam swoje idee, normy, wartości oraz obyczaje, ale także ingeruje w nawet najbardziej intymne rejony naszego życia.
Pier Paolo Pasolini’s work has always attracted controversy and divided the audience into die-hard supporters and those who categorically rejected his works. Lipowicz attempts to analyse and interpret Pasolini’s last film Salo, or the 120 Days of Sodom (Salo o le 120 giornate di Sodoma /1975/) from the philosophical and sociological point of view. He argues that Salo is an inconvenient and therefore proscribed masterpiece of cinema, and that it shows the transition of the Western culture from modernity to post-modernity in a critical and pessimistic manner. From the contemporary perspective this film is an important reminder that we should not forget that under the guise of social diversity, we, supposedly free citizens, are forced to live in and participate in consumer culture, which not only imposes on us its ideas, norms, values and customs, but also interferes with even the most intimate areas of our lives.

Opis:
Autor podejmuje zagadnienia produkcji, egzegezy i kontekstów ideologiczno-politycznych pierwszego włoskiego filmu montażowego La rabbia, autorstwa Piera Paola Pasoliniego i Giovanniego Guareschiego. Film stworzony w 1962 r., na podstawie materiałów filmowych gromadzonych przez dwie dekady przez kronikę filmową Mondo Libero, miał przedstawić problemy współczesności z dwóch przeciwstawnych pozycji ideologicznych: lewicowej, reprezentowanej przez Pasoliniego, oraz prawicowej, reprezentowanej przez Guareschiego. W swoim tekście Jóźwiak zakwestionował dotychczasowe interpretacje tego filmu. Wnikliwa analiza warstwy dialogowej oraz materiału wizualnego ukazuje wątpliwą z dzisiejszej perspektywy pozycję polityczną Pasoliniego wobec reżimu sowieckiego, na którą składa się m.in. usprawiedliwianie inwazji sowieckiej na Węgry w 1956 r. i etyczna relatywizacja polityki sowieckiej. Z drugiej strony, analiza prawicowej, „faszystowskiej” części Guareschiego prowadzi do zaskakujących wniosków, dotyczących zakamuflowanego wpływu jego myśli na późną postawę polityczną Pasoliniego. W tym świetle La rabbia jawi się jako przełomowy film w ewolucji myśli i twórczości Pasoliniego.
The author deals with the production, exegesis and ideological and political contexts of the first Italian compilation film La Rabbia (Anger) by Pier Paolo Pasolini and Giovanni Guareschi. The film created in 1962, based on film footage collected by the film chronicle Mondo Libero for two decades, was to present the problems of modernity from two opposing ideological positions: leftist, represented by Pasolini, and rightwing, represented by Guareschi. In his text Jóźwiak questions the previous interpretations of this film. An in-depth analysis of the dialogue layer and visual material reveals the political position of Pasolini, which from today’s perspective raises doubts, towards the Soviet regime, which consists of, among others, justification of the Soviet invasion of Hungary in 1956 and ethical relativization of Soviet policy. On the other hand, the analysis of the right-wing “fascist” part of Guareschi leads to surprising conclusions regarding the camouflaged influence of his thoughts on Pasolini’s later political attitude. In this light La Rabbia appears as a ground-breaking film in the evolution of Pasolini’s thought and creativity.

Opis:
Under eccentric load, a single column pier bridge often overturns. In order to study the anti overturning performance of a single column pier bridge, taking the accident bridge in Wuxi as an example, a finite element model is established based on ABAQUS. According to the model simulation results, the relationship between the ultimate rotational load and overturning load of the accident bridge is obtained, and the ratio of the latter to the former is 1.75. Based on the model, the stress state, displacement state, and support state of the accident bridge under dead load, highway class I vehicle load, and accident vehicle load are obtained. Whether the strength and stability of the accident bridge under each load meet the service requirements is analyzed. In order to explore the differences among China, United States, and Japan specifications, the lateral stability of accident bridges is checked. It is found that the safety of the United States and Japan specifications is conservative, but the utilization rate of bridge traffic capacity is low. The safety of China specifications is slightly lower, but it can maximize the bridge’s traffic capacity and judge the ultimate overturning state of the bridge more accurately. The research results can provide technical references for the design and application of a single-column pier bridge.
