The paper deals with two film adaptations of the myth of Orpheus that were made in Brazil in 1959 and 1999. In view of the fact that in both films Orpheus appears as Afro-Brazilian, these two versions of the myth may be related to Sartre’s concept of Black Orpheus, and the movement of Negritude that appeared in Paris in the 1930s as an answer of the black francophone intellectuals to racial myths and colonial stereotypes. Regarding the fact that the European attitude towards ancient Greece is also characteristic of another kind of colonialism that is cultural, based on the claim of exclusive right to this past, the ancient myth that often appears only as a mirror of this relationship, functions in these films as a space for subversion and resistance to different types of colonial power. The films that are the focus of this paper are Black Orpheus (1959) directed by Marcel Camus, which is a French-Italian-Brazilian co-production, and Orpheus (1999) by Carlos Diegues, an entirely Brazilian production. Both films were inspired by the theatrical play written by Vinícius de Moraes, Orfeu da Conceição (1953). Although he himself participated in the production of Camus’s Black Orpheus, in the end he refused to be credited because in the film, the main idea of his drama was lost, which was to show Afro-Brazilians as the main protagonists of the Greek myth pointing out injustices and difficulties of Afro-Brazilian people in social reality, but also in the context of cultural and racial hegemony that clearly claimed the ancient Greek myth to be the heritage of European white men.  Similarly, disappointed, Carlos Diegues decided to make another film together with Vinícius de Moraes. However, the plan was interrupted by Moraes death in 1980, but Diegues succeeded in filming it in 1999. The paper compares the two films focusing on the question to which extent these films challenge or confirm European cultural elitism, racial stereotypes and class inequalities.

Abstract. Noise studies of planar thin-film Ni-P resistors made in/on Printed Circuit Boards, both covered with two different types of cladding or uncladded have been described. The resistors have been made of the resistive-conductive-material (Ohmega-Ply©) of 100 Ώ/sq. Noise of the selected pairs of samples has been measured in the DC resistance bridge with a transformer as the first stage in a signal path. 1/f noise caused by resistance fluctuations has been found to be the main noise component. Parameters describing noise properties of the resistors have been calculated and then compared with the parameters of other previously studied thin- and thick-film resistive materials.

Essentially non-oscillatory (ENO) and weighted ENO (WENO) schemes were designed for solving hyperbolic and convection–diffusion equations with possibly discontinuous solutions or solutions with sharp gradient regions. The main idea of ENO and WENO schemes is actually an approximation procedure, aimed at achieving arbitrarily high-order accuracy in smooth regions and resolving shocks or other discontinuities sharply and in an essentially non-oscillatory fashion. Both finite volume and finite difference schemes have been designed using the ENO or WENO procedure, and these schemes are very popular in applications, most noticeably in computational fluid dynamics but also in other areas of computational physics and engineering. Since the main idea of the ENO and WENO schemes is an approximation procedure not directly related to partial differential equations (PDEs), ENO and WENO schemes also have non-PDE applications. In this paper we will survey the basic ideas behind ENO and WENO schemes, discuss their properties, and present examples of their applications to different types of PDEs as well as to non-PDE problems.

Abstract Background Idiopathic Pulmonary Fibrosis (IPF) is a degenerative interstitial lung disease with both a poor prognosis and quality of life once the diagnosis is made. In the last decade many features of the disease have been investigated to better understand the pathological steps that lead to the onset of the disease and, moreover, different types of biomarkers have been tested to find valid diagnostic, prognostic and therapy response predictive ones. In the complexity of IPF, microRNA (miRNAs) biomarker investigation seems to be promising. Methods We analysed the expression of five exosomal miRNAs supposed to have a role in the pathogenesis of the disease from serum of a group of IPF patients (n = 61) and we compared it with the expression of the same miRNAs in a group of healthy controls (n = 15). Results In the current study what emerged is let-7d down-regulation and, unexpectedly, miR-16 significant down-regulation. Moreover, through a cross-sectional analysis, a clustering of the expression of miR-16, miR-21 and miR-26a was found. Conclusions These findings could help the individuation of previously unknown key players in the pathophysiology of IPF and, most interestingly, more specific targets for the development of effective medications.

Abstract Despite the well-established benefits of social participation for individuals and communities, little is known about how it varies throughout the life course. Drawing upon data collected between 1957 and 2011 by the Wisconsin Longitudinal Study (22,023 observations from a cohort of 6,627), this study provides four valuable results. One, I find evidence of five distinct social participation trajectories between the ages of 35 and 71; the majority of which demonstrate social disengagement over time. Two, these participation declines are primarily attributable to changes in meeting friends and group exercise activity. Three, the most pronounced activity differences separating those in more favorable and unfavorable participation trajectories are cultural event attendance and voluntary group membership. Lastly, I identify particular high school activities that are associated with social participation decades later. In total, these results highlight heterogeneity among different types of social activities, and underscore the possible consequences of membership decisions made in early adulthood.

The DNV-RP-C203 Fatigue Design of Offshore Steel Structures is being used by a number of different companies for fatigue assessment of different types of structures. This has resulted in questions to DNV about background for the different sections in the document. It is therefore important that the basis for this document is open to the industry. Quite a lot of the background material has also been published earlier at conferences and in journals. In some situations it has been found that the content can be improved to better suite the industry. The document is presented in an electronic version making revisions easy. Therefore it has been revised several times since the last official presentation of a revision in 2005. The present paper gives an overview of the most significant changes made in the document since the 2005 revision. Some of these changes are already included in the present version of DNV-RP-C203. The remaining changes will be included in a revision dated 2010.

Enormous progress has been made in the last few years towards the elucidation of the mechanism of protein synthesis, and great interest is centred on the steps leading to cellular differentiation and specific protein synthesis. We know that genetic information is passed on from one generation of cells to the next by deoxyribonucleic acid (DNA), and that this material directs all protein synthesis by the intermediary of the different types of ribonucleic acid (RNA). A simple in vitro system described by O'Brien (1959) seemed to offer an excellent tool for the study of the differentiation of the blood islands, and the initial formation of a well-known protein, haemoglobin (Hb), in chick embryonic tissues. After de-embryonation, chick blastoderms, from the stage of primitive streak onwards, can be cultured in vitro on a saline agar medium supplemented with glucose.

The paper deals to the finds from the barrow near the Shumeiko farm in the Sula river basin (now Sumy region of Ukraine) which was excavated by Sergei Mazaraki in 1899. Objects of Scythian culture were found in the mound: weapons, horse bridles, and vessels. Mikhail Rostovtsev mistakenly attributed to these finds the fragment of ancient Greek kylix of the end of the 6th century BC. Modern researchers date the barrow assemblage near the Shumeiko farm to the first half of the 6th century BC (Igor Bruyako, Denis Grechko, Denis Topal, Oleksandr Shelekhan). Sergey Polin attributes it to Early Scythian time. In the paper three precious items from the barrow are described in detail. This is a sword, the handle of which is plaqued with gold. The ancient craftsman used the granulation technique for decoration. Not only the ancient Greek jewelers used this technique. The masters of Urartu applied it as well. It was used in the decoration of the sword from the Kelermes barrow in the Kuban region, as well as on various adornments. The iron sword has an original shape and belongs to the Shumeiko type (according to Denis Topal, Oleksandr Shelekhan). Such swords were most common in the first half of the 6th century BC. The scabbard was decorated by the gold plate with images of animals and the gold tip. The analysis shows that the images of wild goats and predators are made in the early Scythian animal style. The sheath tip also corresponds to the early Scythian tradition and finds analogies in the Pre-Scythian time. On the contrary, at a later time (the end of the 6th — beginning of the 5th century BC), according to other principles (barrow No 6 near the Oleksandrivka village, Gostra Mogyla near the Tomakovka village) the tips of the scabbard were made. Near the sword the gold plate in the form of a running hare was found. It was made in the Scythian animal style. This plate was probably part of the sheath decor and adorned a side leather ledge that helped to attach the scabbard to the belt. A preliminary conclusion is made about the belonging of precious items from the Shumeiko barrow to the Kelermes horizon of antiquities of the Early Scythian culture.

AbstractThis paper examines how maize and blood were central elements in ancient Zapotec religious practices and how they were conceptually linked. I analyze the iconography of different types of Classic period Zapotec ceramic effigy vessels. Using a comparative approach, I identify elements that frequently appear on the urns, such as maize plants in different stages of growth, or representations of the milpa. Framing these observations with early colonial historical accounts and ethnographic studies, I suggest that the main theme involved in these ancient representations was fertility, maintained by a sacred pact forged between humans and their deities that required sacrifice through bloodletting. The drawing and offering of blood insured a cycle of sustained and abundant growth for their most important crop: maize. Though many advances have been made in recent years regarding Zapotec iconography, I will offer some new interpretations regarding specific forms represented on the urns.

The Way

Here we present a translation into Spanish of the medieval English poem titled “Sir Orfeo”, which was composed in the late 13th or early 14th centuries within the WestminsterMiddlesex area. Our main spur has been to disseminate it amongst the modern Spanish-speaking readers due to its literary beauty and its story, a story which is not certainly innovative; however, it is innovative as to the way its author has succeeded in adapting the classical or Ancient Greek myth to the medieval English mindset of the readers or listeners of the time so as to arouse their interest, entertain them and teach them with a didactic purpose. The poem comprises all the elements inherent to a prototypical lay (or lai): a knight-king, a love story, a physical and spiritual quest, the otherworld (or fairyland), and moral and spiritual values which should be taken into account by the audience. We have attempted to make the translation of “Sir Orfeo” into Spanish as faithful as possible regarding the original English poem in order to maintain its literary essence, freshness and character. “Sir Orfeo” was a very popular poem in its time, and there is no doubt that it will become popular again in the 21st century in the light of different perceptions and approaches.
