Opis:
The postmodern architecture of the last third of the XX century saw a steady tendency of appealing to classical heritage aimed at combining modern technologies and historical associations with classical architecture. The work considers postmodern urban planning concepts of the late XX-the beginning of ХХI centuries. Methods of interpreting the order system in the architecture of postmodernism are analyzed by comparing such theoretical concepts as R. Bofi ll›s industrial classicism, the new urbanism of L. and R. Krier, the theory of the city by Aldo Rossi. Architects postmodernists searching for sense and architectural language began to address to the historical past, using signs and images of classical architecture. Leaders of postmodern movement, trying to return to architecture the «eternal values» lost by modernism, opened a way for new creative searches and transformation of the order system elements. Its representatives were attracted by the «double code» of the order architecture, which allowed to solve complex town-planning problems. Postmodernism declared the idea of «architecture parlante». The notion of «postmodern classicism» disguised the compositional search for dialogue with any classical epoch – antiquity, renaissance, baroque, classicism itself. The order language of these epochs, possessing a tremendous potential of utterance, allowed the architect to create all the new meanings and texts. The article discusses the change of semantic meanings occurring in modern urbanism, the interpretation of order compositions, the notion of «order tradition» and the expansion of the semantics of the order system in historical and cultural context. The article shows that the theory of postmodernism actualized the notion of «order tradition» and expanded the semantics of the order system by its application in modern city planning concepts.

Luigi Rossi, Il Palazzo incantato d’Atlante, lament of Alceste, tonal experiment
Opis:
The subject of the article is Scene 6 from Act III of Luigi Rossi’s musical drama Il Palazzo incantato d’Atlante (1642) to a libretto by Giulio Rospigliosi. This particular scene is worthy of attention, because the composer has given it a thoroughly unique musical setting as compared to early Italian drammi per musica. It not only features more than one key signature sign — two sharps appear at the clefs — but also five sharps as accidentals in the music itself, thus using rare pitch material for late sixteenth and early seventeenth century output. The composer resorts to transposing the a-aeolian mode by a whole tone upwards, thus emphasizing b as finalis (not included in the canon of finales, even in the dodecachordal system), and likely purposefully choosing a rare key in late Renaissance and early Baroque music, one that carries a pointedly expressive sense. He simultaneously enriched — with such ‘sharpened key’ as background — the monologue’s pitch material, radically mining the tendency to the durus tonal sphere. In tandem, the phenomena appear here for the first time on the terrain of Italian dramma per musica. The reason for introducing this compositional solution was the content of Giulio Rospigliosi’s libretto, laden with nearly harsh words relating Lidia’s cruelty and Alceste’s suffering. This text also demanded an extraordinary musical setting.

Opis:
A three-dimensional electromagnetic crystal is employed as a directivity-enhancing superstrate for planar antennas. The crystal is a woodpile made of alumina rods. In a shielded anechoic chamber, the performance of a patch antenna covered with the woodpile is measured. The superstrate is positioned at different distances from the antenna and its orientation is varied in the 8–12 GHz frequency range. The return loss, gain and radiation pattern in the E- and H-planes are measured. The electromagnetic behavior of Fabry-Perot cavities with woodpile mirrors, equivalent to the compound radiator, is also studied. The main effect of the crystal on the antenna performance is an enhancement of about 10 dB in maximum gain. A rather complete series of experiments is presented, highlighting the role of the periodic structure in the directivity enhancement and allowing a deeper understanding of the electromagnetic phenomena involved in EBG resonator antennas. Benefits and disadvantages of this kind of antennas are discussed and ideas for future research are given.

Opis:
The article presents a coherent methodology of a multiple criteria evaluation of suppliers in furniture industry covering: the definition of a set of variants - laminated chipboards suppliers, the definition of a consistent family of criteria that allows for their comprehensive evaluation, modelling of decision maker’s (DM’s) preferences (including: the definition of the importance of criteria and the DM’s sensitivity towards changes of criteria values), and finally computational experiments resulting in the final ranking of suppliers. Six suppliers have been taken into consideration. In the family of criteria evaluating the suppliers, 9 measures have been taken into account. These have included, among others: product price, product quality, timeliness and reliability of delivery or cost of delivery. In the computational phase a selected MCDM/A ranking method which is Electre III/IV has been applied.

Opis:
The article presents the results of a test on the resistance of Neolithic waterlogged beech wood (Fagus sylvatica L.) to destruction by subterranean Reticulitermes lucifugus Rossi. Methodology consistent with the ASTM D 3345-08 Standard was applied in the experiment. In the coercion test, the modern beech wood was destroyed at an intermediate stage between light attack and moderate attack with penetration, whereas the pine sapwood was heavily damaged. Under the same conditions, the waterlogged beech wood was seriously damaged or completely destroyed by the termites. However, unlike the modern pine and beech wood, all the termites died after feeding on the waterlogged beech wood. In spite of the complete destruction of the waterlogged beech wood in the coercion test, it seems that under natural conditions where there is a possible choice between different wood species, the infestation by termites of waterlogged wood uncovered in archaeological work does not necessarily happen. Wood containing few nutritional substances and substantial lignin, as well as having a high moisture content facilitating the development of parasitic microorganisms, will deter termites.

Opis:
The paper describes the cases of 3 female health operators with implanted copper IUDs, developing menometrorrhagia some months after an increase of the working time in a Magnetic Resonance Imaging (MRI) Unit (1.5 T), that progressively disappeared when the previous organization, involving discontinuous work shifts at MRI, was re-established. No known factors possibly related to menometrorrhagia were evidenced in the 3 operators, supporting the hypothesis of a role of the exposure to the electromagnetic fields (EMF) induced by the MRI system in symptoms induction. The possible mechanism remains unsettled, but menometrorrhagia might be triggered by a phlogistic stimulus caused by EMF, possibly the lowfrequency currents induced in the wires of the IUD during the movements of the operator inside the static magnetic field generated by the MRI permanent magnet. Until now, the problem of possible interactions between copper IUDs and EMF induced by MRI has been considered in patients undergoing imaging, but the possible risk in MRI Units operators has been largely neglected. To our knowledge, the occurrence of menometrorrhagia is not routinely checked in health surveillance of MRI operators, so these symptoms can pass unnoticed, especially if they are transitory. Therefore, underreporting is rather possible. The cases described here support the need for further research on this topic, especially considering the progressive diffusion of more powerful MRI scanners (3 T and more), and of the interventional magnetic resonance imaging, both potentially involving higher EMF exposures, and a large number of MRI female operators, possibly using IUDs. The possibility that MRI operators with implanted metallic IUDs can be included in the group of “workers at particular risk” according to the EU Directive 2004/40/EC should be considered.

Opis:
This article presents the new Italian database of physical agents, which is available at http://www.portaleagentifisici.it. It supports in risk assessment employers who have to comply with Italy’s Legislative Decree 81/2008 (transposing into law European Union Directives 2003/10/EC, 2002/44/EC, 2004/40/EC and 2006/25/EC). The database currently contains measurements and declared European Community (EC) values from over 2540 machines; in particular, the database hosts data on mechanical vibration from over 1430 hand-held power tools (e.g., pneumatic and electric hammers, chainsaws, grinders, drills, sanders and saws) and from over 1020 whole-body machines (e.g., buses, fork lifts and wheel tractors). The database is continuously updated as soon as new experimental and declared data are acquired.

Opis:
European Directive 2004/40/EC on occupational exposure to electromagnetic fields (EMF), based on the guidelines of the International Commission on Non-Ionizing Radiation Protection, was to be implemented in the Member States of the European Union by 2008. Because of some unexpected problems the deadline was postponed until 2012. This paper reviews some of the problems identified and presents some suggestions for possible solutions based on the authors’ experience in assessing occupational exposure to EMF. Among the topics discussed are movement in static magnetic fields, ways to time average extreme low frequency signals, the difference between emission and exposure standards, and ways of dealing with those issues.
