Bioplastics constitute a great opportunity for agriculture, industry and environment. On the one hand, the basic raw material used to fabricate bioplastics is made from renewable agricultural materials, on the other hand, bioplastics have a wide application as packaging and protections in the food and non-food industry as catering products as protection films and foils and as compostable items in agriculture. Also very important is that after achieving the purpose for which they are produced, bioplastics become waste and their cycle is closed as they can be used as compost for agriculture.

<p>The city of Évora, a World Heritage Site recognized by UNESCO in 1986, also owes this recognition to the stones that built its monuments and preserve them until today.</p><p>This work brings together the contributions that we have gathered over the past three decades and allow us to have a very complete idea, not only about the materials used in the hundreds of monuments and historic buildings but also about their provenance. If some materials are so emblematic that they allow an immediate identification with the naked eye, others needed more sophisticated and precise techniques so that there was no doubt about their origin.</p><p>The igneous rocks and gneisses of granite composition are part of the “Massif of Évora” on which the city is built. Thus, and quite naturally they are by far the most represented group in monuments from all historical periods. Its function is essentially structural, but there are also functional, ornamental and decorative objects. For example, the oldest megalithic structures found in the vicinity of the city are made up of large granite blocks that often had to be transported to their locations.</p><p>On the other hand, many gargoyles and statues that decorate the churches are also made up of these granite rocks. On these, the natural erosion of centuries of exposure to the environment has led to a state of alteration, sometimes very accentuated, which would justify its replacement by replicas sculpted in similar rocks. Provenance studies have made it possible to identify old quarries in the vicinity of the city where, on the one hand, the ancient rock extraction techniques can be observed and on the other hand, they allow the obtaining of the raw material necessary for these restoration and conservation works. In any case, they are places that need to be inventoried and protected, with the municipality already aware of their existence.</p><p>As well as the monuments of the Roman Period, also the structures of the Medieval Period, such as the city walls, the Cathedral (started to be built in 1186 AD) and all the great churches, were also built with these granitoids.</p><p>In addition to these rocks, many others of multiple varieties and origins are present. The marbles, especially the Estremoz Marbles (Global Heritage Stone Resource), are ubiquitous in the city, but there are also emblematic marbles from other places, some easily identifiable (ie Viana do Alentejo, Escoural, Trigaches, Serpa and Vila Verde de Ficalho, for presenting mineralogy, textures, colors and patterns which, together with more recent analytical techniques, have confirmed its provenance.</p><p>Sedimentary rocks, with emphasis on Portuguese Mesozoic limestones, ie Lioz - GHSR and Brecha da Arrábida - GHSR candidate, among others more rare and with very specific use in ornamental details, are also present and contribute to enrich a heritage in stone that makes this city so special and very popular with tourists of all nationalities.</p><p>Acknowledgments: the authors thank to FCT for funding the ICT (UID/GEO/04683/2019), as well as COMPETE POCI-01-0145-FEDER-007690.</p>

Stiegler argued in Cinematic Time and the Question of Malaise (the third volume of Technics and Time) that we must refer to archi-cinema just as Derrida spoke of archi-writing. In this article he proposes that in principle the dream is the primordial form of this archi-cinema. The archi-cinema of consciousness, of which dreams would be the matrix as archi-cinema of the unconscious, is the projection resulting from the play between what Husserl called, on the one hand, primary and secondary retentions, and what Stiegler, on the other hand, calls tertiary retentions, which are the hypomnesic traces (that is, the mnemo-technical traces) of conscious and unconscious life. There is archi-cinema to the extent that for any noetic act – for example, in an act of perception – consciousness projects its object. This projection is a montage, of which tertiary (hypomnesic) retentions form the fabric, as well as constituting both the supports and the cutting room. This indicates that archi-cinema has a history, a history conditioned by the history of tertiary retentions. It also means that there is an organology of dreams.

Статья посвящена новым, дополнительным критериям выделения посуды одного мастера. Экспериментально было доказано, что тулово сосуда - наиболее устойчивая его часть. А из его параметров наиболее устойчивым оказался максимальный диаметр. Используя два параметра тулова: его общую пропорциональность и максимальный диаметр, автор выделил из всей посуды Волосово-Даниловского могильника посуду, сделанную по одной и той же форме-модели. Сопоставление сосудов, сделанных по одной форме-модели, с одинаковыми исходным сырьем, составом формовочной массы сосудов и составом шамота в ней позволило выделить посуду одного мастера. Таким образом, предложен еще один критерий для выделения посуды одного мастера: близкие формы-модели, с помощью которых лепились сосуды. Разработанная автором методика выделения посуды гончаров-левшей, с одной стороны, подтвердила правильность методики анализа форм сосудов, а с другой - позволила выявить большее число разных гончаров, посуда которых сопровождала погребенных в могильнике индивидов. The paper is dedicated to new, additional criteria for singling out vessels made by one craftsman. It has been proven experimentally that the vessel body is the most stable element. Regarding its characteristics, the maximum diameter turned out to be the most stable. Using two characteristics of the body, i.e. its proportions and its maximum diameter, the author selected vessels made with the use of the same model shape among all vessels coming from the Volosovo-Danilovo burial ground. Comparison of the vessels made with the use of the same model shape, the same raw material, the same composition of clay paste and proportion of grog in it provided an opportunity to single out vessels made by one craftsman. Therefore, one more criterion for singling out vessels made by the same craftsman is proposed, i.e. a similar model shape used in making vessels. The methodology for identifying left-handed potters developed by the author, on the one hand, confirmed that the methodology of analyzing vessels shape was correct and, on the other hand, made it possible to identify a greater number of various potters whose vessels were placed into the graves as funerary offerings.

AbstractThis study is guided by the idea that the totality of human self-relationships is dependent on a respective other, in order to be able to develop and in extreme cases sustain oneself. This is true even with regard to the phenomenal experience. On the one hand, it is determined how anthropological basic constellations are linked to relevant ethical questions of lifestyle and coping with existence, and, on the other hand, a lifestyle technique and ethical improvement are considered. Emotional and affective self-relationships in particular are examined to determine the phenomenal content of human self-relationships. In the first section, a model is presented on how inner life and thus a self is created in dialogical structures. In the second part, a traditional monologic technique is described as a dialogue with oneself, with whose help an inner life is further developed and unfolded. The third section shows how the effort towards self-preservation refers to dialogue scenarios.

This chapter focuses on part II, Chapter 24 of Maimonides’ Guide of the Perplexed, which discusses the incompatibility of the models used by professional astronomers with the basic tenets of the Aristotelian world-view. On the one hand, the epicycles and eccentrics employed by astronomers seem to violate the principle that the motion of the heavenly bodies be uniform, circular, and about a fixed centre. On the other hand, the results achieved through the use of these very devices are startlingly precise. This, Maimonides says, is the ‘true perplexity’. The chapter then looks at three aspects of this true perplexity. It also compares the views expressed in the Guide with the rules laid down in the third chapter of the ‘Laws Concerning the Basic Principles of the Torah’, which forms the first section of the Mishneh Torah. It is particularly concerned with two questions: did Maimonides consider the true configuration of the heavens to be inscrutable? And can a close reading of both texts offer any clues about this true configuration? Finally, the chapter considers the views of some of Maimonides’ followers on these questions.

This chapter examines The Human Centipede, Nymphomaniac, and Videodrome; films that push the boundaries of human objectification. The chapter draws on the works of Georg Wilhelm Friedrich Hegel and Jean-Paul Sartre, highlighting an ontological distinction between being “in-itself” and being “for-itself.” It is argued that though the objectification of key characters in these films, on the one hand, promotes a sort of nihilistic reduction of humans to meaningless bodies in motion, on the other hand, this same reduction potentially provokes a sense of sympathy in viewers who are also embodied, and thus can see their own condition reflected in the experiences of the characters who suffer on screen. Depictions of others as meaningless matter remind audiences of their own corporeal nature (being in-itself), disgusting, titillating, and amusing them, but also potentially moving them to empathize with the consciousnesses presumed by analogy with themselves to exist within the bodies depicted on screen (being for-itself).

Three major reshuffles delineate two families (α and β) within the manuscript tradition of the Commentary on Matthew by Hilary of Poitiers. In the first two cases (3, 2; 9, 7-9), J. Doignon in his critical edition (SCh 254 and 258) favored the text of the α family, judging that the β family generally attests to numerous revisions intended to suppress difficult lectiones. In the third case, on the other hand, he adopted the short text of the β family, thus demoting two short passages in 33, 5 specific to the α family. This article shows that on the one hand the language of these passages is attributable to Hilary and on the other their content fits perfectly with his exegesis. It thus argues for their authenticity.

Political Legitimacy in Middle Africa is an insightful, refreshing, and original book that refines and expands our understanding of the so-called “politics of the belly.” A phrase made famous by Jean Francois Bayart (The State in Africa: The Politics of the Belly, 1993), the politics of the belly is the phenomenon of “eating” the fruits of power. The extent to which officeholders monopolize or share these fruits with the larger community has, however, significant consequences for their legitimacy. As Michael Schatzberg suggests, a “moral matrix of legitimate governance” (p. 35) embedded in familial and paternal metaphors shapes these belly politics. In turn, he argues that the moral matrix is rooted in four major premises. The first and second are related to the image of the ruler as a “fatherchief,” who has the obligation, on the one hand, to nurture and nourish his “family,” and on the other hand, to punish his “children” when necessary and pardon them when they truly repent. The third premise concerns the status of women in society; while they are not considered equal to men, rulers should, nonetheless, respect their role as “counselors and advisers.” The fourth premise “holds that permanent power is illegitimate and that political fathers…have to let their children grow up, mature, take on ever-increasing responsibilities in the conduct of their own affairs, and eventually succeed them in power” (p. 192).

Although the idea of r2p had been enshrined in the Constitutive Act of the African Union (au) shortly before the term was coined by the iciss, the au has been slow to live up to the commitment. Balancing r2p, on the one hand, with non-interference within the domaine reservé of the state, on the other hand, has proven an uphill battle. r2p sceptic member states have persistently opted for non-interference, and at most, a “non-indifference” approach representing a non-committal stance with regards to r2p. This paper offers reflections about the particular African construction of the third r2p “collective global” pillar, and explains the African reticence about the original iciss and 2005 World Summit Outcome versions of r2p. It expounds on the key reasons for this tempered reception and sheds light on the global governance security challenge as it plays out in the un-au politics of regional collaboration.

In this concluding article we discuss the three approaches to biographical stress and coping research presented in this issue, under four main headings. The first topic comprises the comparison of the three approaches with regard to their biographical features. In a second part we turn to the issue of coping and examine differences as well as similarities between the coping concept of Hans Thomae, on the one hand and that of Lazarus and Folkman on the other hand. The third and fourth of our discussion points deal with two central topics, that are accentuated in present personality psychology: the person‐situation issue and the idiographic‐nomothetic debate. With regard to both topics, we discuss the ideas and research findings which Lazarus and Folkman, as well as Thomae are contributing to these issues. We conclude our discussion of biographical approaches to stress and coping by proposing a person‐centred approach, that can be regarded as a further development of theoretical conceptualizations contained in the approaches of Lazarus and Thomae.
