During recent herbarium and field studies three names of Rubus sect. Corylifolii ser. Subcanescentes were re-assessed. Rubus macrostemonides was typified with a neotype specimen from Salzburg (Austria), and its identity with R. baruthicus was shown (the previous name has the priority). Its presence at the Austrian locus classicus was confirmed also recently, this locality represents the easternmost occurrence of the species. The name R. holosericeus was (mis)applied for a long time for a widespread taxon occurring southeast of the Alps that is not at all present in the original material. This name was lectotypified with a specimen from Styria (Austria) here as a hitherto overlooked regional species recently recorded in Austria, Hungary and Slovenia. The taxon that was formerly (mis)identified as R. holosericeus has proven to be identical to R. semitomentosus, which is lectotypified here with a specimen from Hungary. For both taxa clarified here is, beside a circumstantial assessment of the type material, an improved morphological characterization and circumscription of distribution and habitats presented.

Physoptychis is recognized as a genus of two species: P. caspica, a relatively widespread in SW Asia, and P. haussknechtii, an endemic of inner Anatolia. Nomenclature of both taxa is updated, and three new synonyms are established. Of them, the poorly known Fibigia thesigeri and Vesicaria physiphora are proven to be conspecific with P. caspica, while the recently described P. purpurascens is found to be indistinguishable from P. haussknechtii. The approximate locus classicus of V. physiphora, hitherto unclear, is revealed, and the name is typified. Notes on the original material and typification of Crambe caspica [≡ Physoptychis caspica] are provided. Morphological characteristics and distribution of P. haussknechtii are updated.

Campanula rotundifolia var. bulgarica Nejceff, a neglected taxon in the Bulgarian flora with currently uncertain status, was collected and studied at its locus classicus in the Sokolna (Koru Dere) Reserve of Central Stara Planina Mountain. A detailed morphological analysis of Nejceff’s original material and other related species clearly indicates that this is a distinct taxonomic entity worthy of species rank. Campanula nejceffii, stat. nov. is distinguished by a combination of its pubescent habit, ovoid to elliptic-lanceolate cauline leaves, clearly spreading to reflexed narrowly triangular-lanceolate calyx teeth, erect buds and flowers. Complete species description and comparison with selected species in the C. rotundifolia group are given. The lectotypes of two taxa—C. rotundifolia var. bulgarica Nejceff and C. rotundifolia subsp. neicevii f. pirinica Stoj. & Acht. are designated by the authors.

Verbascum auriculatum, a name for a species discovered during Sibthorp’s first expedition in the Eastern Mediterranean, had long been sunk into synonymy of V. mucronatum. Surprisingly, however, the original material of this name was found not to match V. mucronatum but V. propontideum, a very distinct species, remarkably dissimilar to V. mucronatum. V. auriculatum is lectotypified and resurrected since V. propontideum represents a younger synonym. The species is endemic to the S.E. Aegean region, whereas Sibthorp has left no indication of where and when he collected the plant. A hypothesis on the possible locus classicus and date of the original collection is presented.

This book draws on declassified documents from six countries and original material in Arabic, German, Hebrew, and Russian to present a new understanding of Egypt's disastrous five-year intervention in Yemen, which Egyptian president Gamal Abdel Nasser later referred to as “my Vietnam.” The book argues that Nasser's attempt to export the Egyptian revolution to Yemen played a decisive role in destabilizing Egypt's relations with the Cold War powers, tarnishing its image in the Arab world, ruining its economy, and driving its rulers to instigate the fatal series of missteps that led to war with Israel in 1967. Viewing the Six Day War as an unintended consequence of the Saudi–Egyptian struggle over Yemen, the book demonstrates that the most important Cold War conflict in the Middle East was not the clash between Israel and its neighbors. It was the inter-Arab struggle between monarchies and republics over power and legitimacy. Egypt's defeat in the “Arab Cold War” set the stage for the rise of Saudi Arabia and political Islam. Bold and provocative, this book brings to life a critical phase in the modern history of the Middle East. Its compelling analysis of Egypt's fall from power in the 1960s offers new insights into the decline of Arab nationalism, exposing the deep historical roots of the Arab Spring of 2011.

The paper summarizes information on chromosome numbers (CNs) of the Grass species (Poaceae) in the flora of Russian Federation, obtained on the original material, most part - from the Russian Far East (RFE). In some species the CNs are known in Russia or in the world only from RFE, in some – from one locality or few, or from one subregion of RFE. The grass species in RFE often occur in mountain regions and near seacoasts; some species are endemics, some were studied near the limits of their geographical distribution areas. The diversity of CNs, the special features of the CNs distribution in some grass groups are discussed. The alien species are abundant in RFE, and their CNs are also involved in the study. For karyologically polymorphous species further studies are needed.

How can scholars critically engage premodern Indic traditions without falling prey to Hindu conservatism or Brahmanical-Hindu apologism? This question is pressing for Indic political theory and contemporary Indian democracy because of ethnically exclusivist, Hindu nationalist movements that have emerged in the late twentieth and early twenty-first centuries. This chapter argues that a positive answer to the question must begin by taking seriously the tremendous pluralism in India’s political and philosophical history, which requires systematically engaging with premodern source material and uncovering the internal pluralism within a longer and larger Brahmanical-Hindu tradition of political thought. The author explains how it is both possible and politically necessary to internally subvert Brahmanical-Hindu political thought, which can help diffuse essentialist and exclusivist arguments coming from the Hindu right. Locating such plurality and engaging in internal subversion can help challenge historical justifications for Indian nationalism and contribute to decolonization, thus contesting the Hindu right on its own conceptual and genealogical turf. To advance this argument, the author provides a critical reinterpretation of the infamous “Puruṣa Sūkta,” which is often viewed as the locus classicus of the modern caste system, providing a novel interpretation that challenges caste hierarchy and supplies new resources for democratic thought and practice in India.

AbstractBrachauchenine pliosaurids were a cosmopolitan clade of macropredatory plesiosaurs that are considered to represent the only pliosaurid lineage that survived the faunal turnover of marine amniotes during the Jurassic- Cretaceous transition. However, the European record of the Early to early Late Cretaceous brachauchenines is largely limited to isolated tooth crowns, most of which have been attributed to the classic Cretaceous taxon Polyptychodon. Nevertheless, the original material of P. interruptus, the type species of Polyptychodon, was recently reappraised and found undiagnostic. Here, we describe a collection of twelve pliosaurid teeth from the upper Albian-middle Cenomanian interval of the condensed, phosphorite-bearing Cretaceous succession at Annopol, Poland. Eleven of the studied tooth crowns, from the Albian and Cenomanian strata, fall within the range of the morphological variability observed in the original material of P. interruptus from the Cretaceous of England. One tooth crown from the middle Cenomanian is characterized by a gently subtrihedral cross-section. Similar morphology has so far been described only for pliosaurid teeth from the Late Jurassic and Early Cretaceous. Even though it remains impossible to precisely settle the taxonomic distinctions, the studied material is considered to be taxonomically heterogeneous.

Blends of two long-chain branched polypropylenes (LCB-PP) and five linear polypropylenes (L-PP) were prepared in a single screw extruder at 240 °C. The two LCB-PPs were self-created via reactive extrusion at 180 °C by using dimyristyl peroxydicarbonate (PODIC C126) and dilauroyl peroxide (LP) as peroxides. For blending two virgin and three recycled PPs like coffee caps, yoghurt cups and buckets with different melt flow rate (MFR) values were used. The influence of using blends was assessed by investigating the rheological (dynamic and extensional rheology) and mechanical properties (tensile test and impact tensile test). The dynamic rheology indicated that the molecular weight as well as the molecular weight distribution could be increased or broadened. Also the melt strength behavior could be improved by using the two peroxide modified LCB-PP blends on the basis of PODIC C126 or PEROXAN LP (dilauroyl peroxide). In addition, the mechanical properties were consistently enhanced or at least kept constant compared to the original material. In particular, the impact tensile strength but also the elongation at break could be increased considerably. This study showed that the blending of LCB-PP can increase the investigated properties and represents a promising option, especially when using recycled PP, which demonstrates a real “up-cycling” process.
